Anonymous users2024-02-05There are many reasons for mistracking, the main ones being low installation accuracy and poor daily maintenance.
During the installation process, the head and tail rollers and the intermediate rollers should be on the same center line as far as possible, and parallel to each other to ensure that the conveyor belt is not biased or less biased.
In addition, the strap joints should be correct and the circumference on both sides should be the same.
In the process of use, if there is deviation, the following checks should be made to determine the cause and make adjustments. The parts and treatment methods that are often checked when the conveyor belt deviates are:
1) Check the non-coincidence between the transverse centerline of the idler and the longitudinal centerline of the belt conveyor.
If the coincidence value does not exceed 3mm, it should be adjusted by using the long mounting holes on both sides of the idler set.
The specific method is which side of the conveyor belt is deflected, which side of the idler set moves forward in the direction of the conveyor belt, or the other side moves back.
2. Check the deviation value of the two planes of the head and tail frame mounting bearing seats. If the deviation of the two planes is greater than 1mm, the two planes should be adjusted in the same plane. The adjustment method of the head roller is:
If the conveyor belt deviates to the right side of the drum, the bearing seat on the right side of the drum should move forward or the left bearing seat move backward; If the belt deviates to the left side of the pulley, the housing on the left side of the pulley should be moved forward or the right housing should be moved backward. The tail drum is adjusted in the opposite way to the head roller.
3) Check the position of the material on the conveyor belt. Material that is not centered on the conveyor belt cross-section will cause the conveyor belt to deviate.
If the material is biased to the right, the belt is deviated to the left and vice versa. When using, the material should be centered as much as possible.
In order to reduce or avoid such belt mistracking, a baffle plate can be added to change the direction and position of the material.

Anonymous users2024-02-04Reasons: 1. The installation quality of the belt conveyor has the greatest impact on the belt deviation, and the belt deviation caused by the installation error is the most difficult to deal with.
2. The frame is skewed. Rack skew includes skew of the center line of the rack and skew of the sides of the rack.
3. The pressure of the rubber plate on both sides of the guide groove is uneven. Due to the uneven pressure of the rubber plate, the running resistance on both sides of the belt is inconsistent, causing the belt to deviate.
Treatment: 1. For the deviation caused by the installation error, the installation error must be eliminated first, and the reconnection of the belt joint must be reinstalled, and the serious skew of the rack must be reinstalled.
2. Adjust the idler group. When the belt of the belt conveyor deviates in the middle of the whole belt conveyor, the position of the roller group can be adjusted to adjust the deviation, and the installation holes on both sides of the roller bracket are processed into long holes, which is convenient for adjustment. The specific method is which side the belt deviates towards, which side of the idler group moves forward in the direction of the belt running, or the other side moves back.
3. Install the differential self-aligning roller set. The differential self-aligning roller group is generally installed every 6-10 groups, and its working principle is to use blocking or roller rotation in the horizontal plane to block or generate transverse thrust to make the belt automatically centripetal, so as to achieve the purpose of adjusting the belt deviation.
Screw conveyor is a machine that uses a motor to drive the screw to rotate and move materials to achieve the purpose of conveying. When the spiral shaft rotates, due to the gravity of the material and the friction generated by it and the tank wall, the material can only move forward along the bottom of the groove of the conveyor under the push of the blades.
1) Check whether the tape and joints are damaged before driving, and if there is damage, repair it in time; Check whether the fixed part is loose, if there is looseness, it should be tightened in time; At the same time, it is also necessary to check whether the upper and lower rollers are damaged and fall off, and if so, they should be replaced in time. On the basis of the above inspection, add lubricating oil to the transmission drum and the reversing roller, the upper and lower rollers, and ensure that the oil volume of these components is sufficient and the lubrication is good, you can send a contact bell signal to the other party (especially the contact bell signal must be sent when the longer belt conveyor is running), and wait for the other party to drive after the force, and then no load test, the time of no load test should generally be 1-2h, but the small should be less than the entire belt length to run a cycle; During the test, the belt should not deviate, the driving device should run smoothly, and there should be no undue friction between the moving parts, the fixed cover and the blanking port. After the test run is normal, it can be loaded. >>>More
Is this still a question, it must have been reworked. Don't care about it, how to install the blades!
The principle of buried scraper conveyor is to rely on the internal friction force and side pressure of the material, in the process of conveying the material, the pressure in the direction of movement of the scraper chain and the pushing force of the lower material to the upper material when the material is continuously fed, the synthesis of these forces is enough to overcome the external friction resistance between the material and the shell when the material is conveyed in the machine tank and the weight of the material itself. The material can form a continuous material flow to move forward regardless of horizontal conveying, inclined conveying and vertical conveying.
The screw conveyor is to use the rotating screw to move the conveyed material along the fixed casing and carry out the conveying work, the head and tail bearings are moved to the outside of the shell, the lifting bearing adopts the sliding bearing and is equipped with a dustproof sealing device, the bearing generally adopts powder metallurgy, the cement is conveyed with felt bearing, and the hanging shaft and the screw shaft are connected by slider. The screw conveyor is generally composed of three parts: the conveyor body, the inlet and outlet and the driving device; The spiral blades of the screw conveyor have three forms: solid spiral surface belt spiral surface and blade spiral surface, wherein, the application of vane spiral surface is relatively rare, mainly used for conveying viscosity and compressibility materials, this spiral suspension type, in the process of completing the conveying operation, has and completes the functions of stirring and mixing of materials at the same time. Compared with other conveying equipment, the screw conveyor has the advantages of small cross-sectional size, good sealing performance, stable and reliable operation, multi-point loading and unloading in the middle, safe operation and easy maintenance. >>>More
