What should I do if a silo of cement brick machine is not fed?

What should I do if a silo of cement brick machine is not fed? There are several situations in which the cement brick machine equipment cannot be moved.

1. Check the phenomenon: The touch screen fault prompt screen of the cement brick machine shows the following: "The mold frame is not damaged at the lower limit or the proximity switch, the hopper cannot move forward or the indenter is not in place at the upper limit, or the proximity switch is damaged, and the jump cannot move forward.

When the touch screen indicates that the mold holder is not at the lower limit or the proximity switch is damaged and jumps and cannot move forward, the possible reasons are as follows:

No reduction of the mold holder or induction iron. The proximity switch at the lower limit of the mold frame is damaged, the circuit of the proximity switch is disconnected or transmitted, and the input terminal of the PLC is damaged.

Exclusion method: If you do not lower the mold holder, you can lower the mold holder to the lower limit position. If the mold holder is already in the lower limit position, check the lower limit of the mold holder to close the indicator of the switch, and then check the port monitor on the touchscreen to see if the lower limit is displayed.

The frame is close to the switch under operating conditions and then checked one by one. Eliminate possible situations of failure.

2 When the touch screen shows that the indenter has not reached the upper limit or the proximity switch is damaged and the jump cannot be performed, it may be due to the following reasons.

Cause of failure: the proximity switch of the indenter is in place or the induction iron is not inducted, the proximity switch of the indenter limit is damaged, the circuit of the proximity switch is damaged or loose, and the input PLC has been damaged.

Exclusion method: If the indenter is not raised to this position, the indenter is raised to the upper limit. If the indenter of the cement brick formwork is at or above the upper limit, please check the upper limit of the indenter.

Check the port monitoring on the touchscreen to see if the upper limit of the indenter is displayed in working condition, and then check every possible situation to eliminate the fault.

The reason for the position deviation of the feeder of the cement brick processing equipment is greater or smaller. If it is too big, it will directly affect the cement brick machine that cannot be fed normally. Therefore, once the position deviation of the silo feeder occurs in the cement brick making machine, the cause can be found and solved in time.

When the feeder truck is feeding, there are two reasons that cause the cement brick silo and the cement is not placed in the middle of the hopper:

1.The limit switch of the limit position after the material is improperly adjusted.

2.The location of the cement brick warehouse is too far or too far.

Ways to rule out this:

1.Adjust the position of the limit switch after the jump so that it jumps back to the correct position.

2.Adjust the cement brick silo to a suitable position.

History. Cement brick making machine is a new type of brick-making equipment designed and manufactured in combination with the current domestic and foreign similar characteristics and market needs. In the seventies of the twentieth century, China introduced foreign eight-hole turntable lime sand brick machine, using river sand and a small amount of fly ash plus cement or aged white ash to press lime sand bricks; However, its disc rotates, can only press one brick at a time, the output is low, the pressure head is rigid and pressed, and the exhaust of the product is insufficient when the large amount of industrial waste fly ash is used, which can not meet the requirements of the national wall reform and conform to the national industrial policy at that time.

In order to increase the output and make up for the disadvantages of its insufficient exhaust products that are easy to stratify, domestic mechanical engineering technicians have developed a crankshaft double-crank mechanical brick press machine that presses two, three bricks or even four bricks each time.

Due to its special design of the preload buffer upper indenter and the adjustable cutting depth. So that it can be qualified for the country's industrial structure policy of using fly ash as a raw material to make bricks as a new wall material at that time. This kind of equipment inherits the advantages of direct stacking without supporting plates of the eight-hole turntable brick press, and also forms 15 17 times per minute with the stability and reliability of its mechanical movement, which ensures the output and product quality of a single equipment.

Because the national standards at that time only had the old standard of lime sand brick and the standard of sintered brick, and the bricks made by this equipment could only be tested by these two standards. In the actual test, it does not meet or exceed the standard of lime sand bricks and sintered bricks at that time from the shape to the quality, according to the natural curing method of similar cement components after the brick is formed, there is no need to build a kiln and do not need to burn, so the name of this "unburned brick" has spread.

Because the traditional sintered bricks need to take a large amount of clay, and even more directly destroy the source of cultivated land, which not only destroys the integrity of China's land resources, but also causes serious pollution to the atmospheric environment after coal combustion in the production of sintered bricks. The Ministry of Construction, the State Economic and Trade Commission, the State Bureau of Quality and Technical Supervision, and the State Building Materials Bureau in 1999 No. 295 document stipulate that 160 cities in China have banned clay solid bricks for a limited time.

In the 21st century, with the development of building materials machinery, new wall materials and equipment has been a hundred flowers, in 2005, with the deepening of the national wall reform policy, the rapid development momentum of the new wall materials equipment "cement brick machine" is like a galloping horse, and manufacturers from all walks of life across the country have been involved in this new industry. With the continuous improvement and in-depth transformation of technology. "Cement brick machine" equipment appears in a hundred schools of thought, the domestic "cement brick machine" is roughly divided into:

Mechanical pressing molding (representing the crankshaft double crank mechanical pressing class and the improved version of the eight-hole turntable pressing class), vibration molding (representing the equipment for producing cement bricks after improving the mold of the block machine), hydraulic + vibration molding (representing the large-scale block molding machine equipment introduced from abroad or improved in China), etc.

No matter what kind of raw materials and what kind of molding method is used, the bricks made by these equipment are naturally cured or autoclaved cured, so the folk still commonly call this kind of brick "unburned bricks", and the equipment that naturally produces this kind of bricks is also called "cement brick making machine".

Ah, why the abominable military training in the summer, summer is the season I like and dislike, because in the summer I can swim and eat ice cream, but the summer is too hot, and although it is hot, our campus is still beautiful.

The little fish in the Xiange Lake are playing happily. The surrounding fruit trees are growing fresh leaves and producing beautiful flowers. The apple tree is like an old grandfather who shades us from the sun.

And the other trees are not idle, they exude an alluring floral fragrance. And the golden weeping willow next to Xiange Lake swayed her graceful figure in the breeze.

On the playground, we athletes are standing upright at a high standard, and the green trees on the playground bring us the breeze and shade, so that we no longer sweat, sitting in the shade and feeling the moisture of the breeze, it is really a fun thing!

I love my campus, and I love the flowers and trees in Xiange Lake. I prefer that tall row of aspen on the playground because it gives us the coolness of summer.

First of all, you should contact the manufacturer, you describe the situation to others, and they will tell you exactly what is wrong.

The relay coil is not electrified

Check the wiring first, or find an electrician to ask, or I can chat privately.

Cement silo is a storage and output of cement set up cylinder, because the cement silo is usually located in the open air, so the cement silo does not cut the situation, the Great Wall Construction Machinery through research found that the cement silo does not cut three situations are more common, namely: cement in the silo discharge port out of the condensation, cement silo under the vertebral mouth plugging and cement silo water into the cement silo caused by cement clot.

Clause. 1. The cement is condensed at the outlet of the silo: the compressor is used to inflate the cement outlet of the cement tank, and the solidified cement will be affected by the impact and will return to a fluid state, so the outlet will not be blocked.

Clause. 2. Plugging of the mouth of the vertebral body under the cement silo: the angle of the outer annular pipe of the contour of the cement silo can be adjusted, and the angle can be adjusted correctly, and it can be replaced if damaged.

Clause. 3. Water enters the cement silo and causes cement curd: if you find the leakage, 80% of it may be that the feed port is not tightly sealed, and you can find it and seal it.

Cause analysis: Under normal circumstances, after the mixing time becomes zero, the mixer will automatically discharge, but in the production process, if the pause button on the operating table is pressed or the prohibitive discharge control on the computer monitoring interface is clicked with the mouse, the mixer will not discharge after the mixing time is up. In addition, the solenoid valve of the discharge door is damaged, the discharge door cannot be opened, and the mixer will not discharge.

Processing process: 1. Check whether the pause button on the console is pressed, and reset if pressed. 2. Check whether the prohibitive discharge control on the computer monitoring interface is activated, and cancel it if it is activated.

3. Check whether the discharge solenoid valve is working properly. Fault phenomenon 2: 1. The discharge door of the mixer has been fully closed, but the door closing signal has not been fed back to the controller; 2. The limit switch is damaged or displaced; 3. A silo has not started batching.

The solutions are as follows: 1. Check the limit control feedback circuit, adjust or replace the limit switch, start the "batching tool" in time to replenish the material, and complete the current batch production in a semi-automatic way; 2. If the discharge indicator light of the upper silo on the operation panel is on, the reason may be insufficient air pressure or serious leakage in the discharge cylinder, and the gas path should be checked in time and the worn parts should be replaced; 3. If the solenoid valve is not powered by 220V AC power, it may be that the intermediate relay coil is burned and the power supply line of the solenoid valve is poorly wired, and the wiring should be checked in time and the relay should be replaced; If the solenoid valve is powered by 220V AC power, it may be that the solenoid valve coil is burned, the valve core is stuck, and the valve body seal is damaged, and the solenoid valve should be replaced in time. Symptom 3:

In the automatic production process, one or more aggregates are weighed in the metering hopper, and the system stops running if the material is not discharged. Cause analysis: 1. The door of the hopper is not in place; 2. There is no discharge output signal of the weighing instrument; 3. The belt conveyor is not started; 4. The fine weighing door of the aggregate scale is not closed in place; 5. The aggregate must be discharged in a defined sequence.

Processing process: 1. Check whether the hopper valve is stuck or the door is not in place, and there is a signal after the door is closed; 2. Check whether the aggregate weighing instrument discharges the output signal; 3. Check whether the belt conveyor is started; 4. Check whether the fine weighing door of the aggregate is closed in place; 5. Check the computer interface, whether the aggregate unloading sequence is defined. Hope it helps!
