The pressure plate of the paper cutter does not return, and the paper cutter cannot be reset to faul

First of all, it is necessary to see whether the knife holder returns to the original position, and the general paper cutter is to add the knife back to the original position to resist the upper limit switch, and then, the jack (pressure plate) is returned to the position upward, and then stopped. If the tool holder returns to its original position, the jack is not returned, the possible reasons are, the relay that controls the jack may have a problem, and second, the solenoid valve that controls the jack may have a problem, and these two possibilities are relatively large.

There are several kinds of problems, and there can be problems with the paper press and the hydraulic system, so check it out.

Summary. The cutter cannot be reset to fault.

Hello dear,, what is the reason why the cutter does not reset:

Electrical failure, behind the transmission mechanism of the paper cutter (turbine box, gear transmission, etc.) is usually equipped with 2 3 travel switches, 1 is mainly used for the cutter after the lowest point, when both hands leave the button, the cutter will automatically return to the highest point (both for the cutter counting function); The other 1 is for the highest stop model, when the position of the travel switch and the contact is incorrect, the cutter will not stop at the highest point (in this case, only the position of the contact or travel switch needs to be adjusted to relieve the fault).

When the brake pads are worn or the clearance is too large, the cutter can not stop at the highest point (adjusting the gap or replacing the brake pads can be solved), or the clutch disc is stuck, resulting in inflexible return (disassemble the brake parts and clean and refuel).

The cutter cannot be reset to fault.

The paper cutter can not reset the fault of your good relatives, what is the reason why the paper cutter does not reset: 1Electrical failure, behind the transmission mechanism of the paper cutter (turbine box, gear transmission, etc.) is usually equipped with 2 3 travel switches, 1 is mainly used for the cutter after the lowest point, when both hands leave the button, the cutter will automatically return to the highest point (both for the cutter counting function); The other is used for the highest point stop difference elimination model, when the position of the travel switch and the contact is incorrect, the cutter will not stop at the highest point (in this case, only the position of the meeting or travel switch needs to be adjusted to relieve the fault).

2.When the brake pads are worn or the gap is too large, the cutter can not stop at the highest point (adjusting the gap or replacing the brake pads can be solved), or the clutch disc is stuck, resulting in inflexible return (disassemble the brake parts, clean and refuel). Hope it helps.

If my answer is helpful to you, please give a thumbs up (comment in the lower left corner), look forward to your like, your work is very important to me, and your support is also the dynamic and vertical momentum of my progress. Finally, I wish you good health and a good mood!

If the knife and the paper press are not returned, it is estimated that the lower limit of the cutter is not sensed, if the knife is returned and the paper press is not returned, then check the knife limit sensor (1) There is a problem with the electrical control part, that is, the proximity switch on the running track of the paper press is not working properly; (2) The pressure spring in hydraulic A may be damaged, or the oil return of the hydraulic cylinder is not smooth; (3) The lift of the paper press is not enough; (4) The mechanical part stores hail and land fibers in the place where the movement is blocked. Solution: In order to troubleshoot the machine as soon as possible and get the cutter back to normal operation, I decided to use the elimination method to introduce all the above possibilitiesThe faulty part is inspected step by step from top to bottom.

First, check the proximity switch on the running track of the sheeting source simulator and find no problems. Then remove the baffle of the oil pool and observe carefully, see that there is no lack of oil in the oil tank, but when the wide paper is pressed, there is a serious oil leakage on the oil circuit plate, and the hand touches it, and it is found that there is a lack of oil return pipe, which causes the oil pump to supply oil and there is air in it to enter the oil cylinder, resulting in an abnormal sound when the paper press is pressed. The solution is:

Install the return pipe first, and then let the paper press down repeatedly to allow the air in the oil circuit to be discharged smoothly until the abnormal sound disappears.

The reason why the paper cutter does not go down The paper press does not go down, and the knife does not go down.

Note: If one of the multiple springs is broken, the multiple springs need to be replaced at the same time, otherwise there will also be uneven pressure and insufficient pressure, resulting in the phenomenon of upper and lower knives. 2. Insufficient hydraulics.

That is, the hydraulic oil in the oil circuit or oil pump is not enough, resulting in insufficient pressure, at this time, it is necessary to find out the cause and prescribe the right medicine. The gap between the toolholder and the slider is too large, and when the wear or adjustment is improper, the gap between the toolholder and the slider is too large (generally, when the toolholder is unstable, it will cause the phenomenon of upper and lower knives.) In this case, the gap between the toolholder and the slider needs to be readjusted.

Extended information: In the actual use process, the cutting object to be faced by the paper cutter is diverse, in addition to paper, cardboard, leather, plastic, cork floor and PS version. Due to the wide variety of materials to be cut, different press pressures should be used accordingly for different materials, and the angle of the cutting knife edge should also be changed to ensure high-quality cutting products.

Phenomenon: When the foot switch is pressed during semi-automatic work, the slide moves down to the left and then rises but does not move to the right. This phenomenon occurs when the proximity switch on the upper left side of the vertical slide is not sensed or there is a problem with the proximity switch.

Solution: Adjust the upper proximity switch sensing or better proximity switch.

2: Phenomenon: The work surface does not suction, and the reason for this failure is that the suction motor is burned.

Solution: The contactor that controls the operation of the motor is damaged, the suction motor rotates, but the control suction solenoid valve is faulty, and the suction selector switch is faulty, and the solution is to repair or replace it.

3: Phenomenon: The rising speed of the vertical slide seat is slow, because the vertical slide seat bearing is oil-free or the cylinder piston is worn, and the magnetic collision bends the shaft;

Solution: Replenish the oil, change the piston password, and adjust the shaft.

4: Phenomenon: When semi-automatic work, step on the foot switch slide and fall, and then rise after release.

Solution: This phenomenon is generally that the proximity switch on the left side of the transverse slide seat is damaged or disconnected, and the solution is to replace the proximity switch or turn on the switch wire.

5: Phenomenon: automatic, semi-automatic start does not fall. This type of failure occurs when the proximity switch on the right side of the transverse slide seat is faulty or not sensitive, the selector switch is faulty, and the interlocking point of the single-action switch is damaged.

Solution: Adjust the proximity switch sensing or replace the right proximity switch, replace or repair the selector switch and single-action switch.

6: Phenomenon: Semi-automatic without stepping on the foot switch and acting immediately.

Solution: Most of the reasons for this kind of failure are the short circuit caused by the damage of the foot switch or the water ingress of the foot switch socket, and the other is the problem of manually starting the button switch. The repair can be done by replacing the switch, socket, or button switch with a new one, or by disassembling the repair-related damaged parts.

7: Phenomenon: Manual, semi-automatic are all inactive, and the power light is on.

Solution: The causes of such failures are that the fuse on the low voltage side is blown out, no air source enters, and all the solenoid valves are faulty. The solution is to change the fuse on the low voltage side, check whether the pressure reaches 4-7kg cm, all the faults of the solenoid valve are very small, most of them are disconnected.

8: Phenomenon: When semi-automatic work, step on the foot switch and the vertical slide seat falls, and the printing seat does not move after moving left.

Solution: The cause of this failure is that the proximity switch on the left side of the horizontal slide seat is not sensed or there is a problem. The solution is to adjust the sensing point of the left proximity switch or replace the proximity switch; There is also a small switch in the foot switch that is stuck and does not operate, which will also cause this failure.

The solution is to adjust, repair or replace the micro switch inside the foot switch.

9: Phenomenon: The work table does not suction, the reason is that the solenoid valve controlled by the suction is bad or the internal block is damaged.

Solution: Replace and repair.

10: Phenomenon: automatic failure to start, this kind of fault is that the micro branch switch of the upper and lower cylinders is normally closed, the contact can not be turned on or the timer is damaged.

Solution: Fix the micro switch, or replace the timer.

Summary. Hello, the reason why the pressure plate of the manual paper cutter does not come: (1) There is a problem with the electrical control part, that is, the proximity switch on the running track of the paper press is not working properly; (2) The pressure spring in hydraulic A may be damaged, or the oil return of the hydraulic cylinder is not smooth; (3) The rebounding force of the paper press is not enough; (4) There is a place where the movement of the mechanical part is blocked.

Solution: In order to eliminate the fault as soon as possible and restore the normal operation of the paper cutter, I decided to use the elimination method to check all the above parts that may cause the fault step by step, from top to bottom. The proximity switch on the running track of the paper press was first checked and no problems were found.

Then remove the baffle of the oil pool and observe carefully, and see that there is no lack of oil in the oil tank, but when the paper press is pressed, there is a serious oil leakage on the oil circuit plate. The solution is to install the return pipe first, and then let the paper press down repeatedly to allow the air in the oil circuit to be discharged smoothly until the abnormal sound disappears.

Hello, the reason why the pressure plate of the manual paper cutter does not come: (1) There is a problem with the electrical control part, that is, the proximity switch on the running track of the paper press is not working properly; (2) The Mengzheng Tan pressure spring in hydraulic A may have been damaged, or the oil return of the hydraulic cylinder is not smooth; (3) The rebounding force of the paper press is not enough; (4) There is a place where the movement of the mechanical part is blocked. Workaround:

In order to eliminate the fault as soon as possible and restore the normal operation of the paper cutter, I decided to use the branch division method to check all the above-mentioned parts that may cause the fault step by step, from top to bottom. The proximity switch on the running track of the paper press was first checked and no problems were found. Then remove the baffle of the oil pool and observe carefully, and see that there is no lack of oil in the oil tank, but when the paper press is pressed, there is a serious oil leakage on the oil circuit plate.

The solution is to install the oil return pipe first, and then let the paper press down repeatedly so that the air in the oil circuit can be discharged smoothly until the abnormal sound disappears.

I'm doing it manually.

Pro, check if the hydraulic oil is enough, try to manually step on the pressure plate, whether it is normal to press down, check whether the two sides of the machine are slippery, whether there is something to resist or stuck, and then see if there is a problem with the program hardware, which causes the pressure plate to be pressed down Check whether there is butter Check whether the screws on the paper cutter are stuck on the pressure plate Remember that Anxin is the first to open and collapse, turn off the power first, and then check Some must be powered on to check.
