There are many kinds of conveyor belt, and there are many kinds of colors. The conveyor belt has a wide range of applications, and because the color will be liked by more users, but the conveyor belt will easily become dirty, and it needs to be cleaned frequently. Then how should the conveyor belt be cleaned more routinely?
The production workshop of the conveyor belt needs to go through a series of cleaning work before production. Some plastic paper and other things will be spread on the ground of the workshop to prevent the conveyor belt from being stained with dust or other dirty things.
But in the process of production, there is still some dust or any other waste debris. If you get it, how do you clean it up?
In general, it can be wiped clean with a wet rag. If you encounter some places that can't be wiped off, you need to use some chemicals to wipe. No melted rubber can be dissolved in benzene, can use cotton or towel dipped in benzene to wipe, must pay attention to: benzene is flammable, is also easy to volatilize, when using must pay attention to safety, do not close to the open flame.
After the conveyor belt is wiped with benzene, the conveyor belt will be clean again, very beautiful.

1) Speed protection of mine belt conveyor.
If the conveyor fails, such as motor burning, mechanical transmission part damage, belt or chain pulled off, belt slip, etc., the magnetic switch in the accident sensor SG installed on the passive parts of the conveyor cannot be closed or cannot be closed at the normal speed, then the control system will be in accordance with the reverse time characteristic after a certain delay, the speed protection circuit will take effect, so as to execute part of the action. Cut off the power supply to the motor to avoid a wider accident
(2) Mine belt conveyor temperature protection.
When the temperature of the belt conveyor is over the limit due to friction between the drum and the belt, the detection device (transmitter) installed closely to the drum will send out an over temperature signal. After receiving the signal, the receiver will delay by 3s to make part of the operation, cut off the power supply of the motor, and the conveyor will stop automatically to protect the temperature.
(3) Coal level protection under the head of mine belt conveyor.
If the coal is piled under the head of a conveyor due to an accident that cannot be operated or the coal gangue is blocked or the coal bunker is stopped due to the full coal bunker, then the coal level sensor DL at the corresponding position contacts the coal and the coal level protection circuit acts immediately to make the next conveyor stop immediately. At this time, the working face continues to produce coal, and the tail of the conveyor will pile coal one by one, and make the corresponding one stop until the transfer machine automatically stops running.
(4) Mine belt conveyor coal bunker coal level protection.
When the coal bunker cannot discharge coal because there is no empty car, the coal level will gradually rise. When the coal level rises to the high electrode, the coal level protection action will be taken. Starting from the first belt conveyor, each conveyor will stop in turn due to the coal pile at the tail
(5) Mine belt conveyor emergency stop and lock.
There is an emergency stop latching switch in the lower right corner of the front side of the control box. By rotating the switch left and right, the emergency stop latching can be implemented in this station or the front conveyor
(6) Mine belt conveyor deviation protection.
If the belt conveyor runs off during operation, the belt edge that deviates from the normal running track will pull down the sensor rod installed next to the conveyor and immediately send out an alarm signal. The maintenance time of the alarm signal can be adjusted in the range of 3-30s according to the need. If timely measures can be taken to remove the deviation during the alarm period, the conveyor can continue to operate normally.
(7) stopover protection of mine belt conveyor at any point midway.
If you need to stop at any point along the conveyor, you should switch the corresponding position to the middle stop position, belt conveyor will stop immediately. If you need to turn it on again, reset the switch first, and then press the signal switch to signal.
(8) Smoke protection for mine belt conveyor.
When smoke occurs due to belt friction and other reasons in the roadway, the smoke sensor suspended in the roadway will play a role in sending out alarm sound, and after 3s delay, it will protect the circuit, cut off the power supply of the motor and play a role in smoke protection.

1. When the wire rope conveyor belt is running, the running speed shall not exceed 0.5 meters per second. For some large and high wear material, the transportation speed of the wire rope conveyor belt should be reduced, the belt should be protected and the service life should be extended.
2. Check the wire rope conveyor belt regularly to ensure that the roller is not covered by materials, that there is no material stuck between the roller and the belt, and that regular lubrication is added to the active part to keep the surface of the wire rope conveyor belt clean.
3. Pay close attention to the location and damage of the steel wire rope conveyor belt, timely adjust the deviated steel wire rope conveyor belt, and timely repair the damaged steel wire rope conveyor belt.
4. Pay attention to the feeding direction of the conveyor belt. Feeding in accordance with the direction of the belt can reduce the impact, reduce the friction on the wire rope conveyor belt and improve the service life.
Five, as far as possible to protect the wire rope conveyor belt from being torn, to avoid the tape by the frame, pillar and block material obstruction stagnation.
Precautions for using side conveyor belt Precautions for using side conveyor belt

Wavy guard conveyor belt is also called skirt conveyor belt, which has two guards on both sides. The two guards are wavy, so it is named wavy guard conveyor belt. When transporting products, it is mainly to prevent material accumulation and slide. So what do we need to pay attention to when using the undulating side conveyor belt? What's the trick?
The use of undulating conveyor belt:
1, after purchase, do not use, do not put directly outside, put in a dry and ventilated place, pay attention to fire, moisture, especially in the finished product warehouse, can not appear Mars.
2. If the undulating guard conveyor belt is installed, the conveyor belt must be installed in the correct order, and the conveyor belt must not be installed in reverse. If the conveyor belt is installed in reverse, it will cause double wear and tear of the conveyor belt, greatly reduce the service life, and the material can not be completed.
3. It is usually necessary to check the retaining edge and partition of the conveyor belt of the wavy retaining edge. Especially after a long time of use, the retaining edge and partition will become loose.
4. The direction and blanking speed of conveying materials are consistent with the direction and speed of conveyor belt.
5, empty machine start, avoid motor overload, undulating guard conveyor belt slip. Remove all materials before shutdown.
6, the use of guard conveyor belt to prevent folding and hard material pressure, should be crimped for use and storage.
7. The tension of the undulating side conveyor belt should not be too large, and the tension should be small.
8. If the undulating conveyor belt slips or cannot be pulled, troubleshooting should be done in time and the tensioning system should be adjusted to keep the elastic device flexible.
9. In the conveying process, do not make the conveyor belt run off or snake. It should be adjusted in time.
Causes and solutions of abnormal noise of belt conveyor Causes and solutions of abnormal noise of belt conveyor
Dec .06.2022
When belt conveyor is running, its transmission device, transmission drum, reversing drum and idler gear set will make abnormal noise when abnormal. According to the abnormal noise, you can determine the fault of the equipment.
(1) Noise when belt conveyor idlers are seriously eccentric
During the operation of belt conveyor, the roller often has abnormal noise and periodic vibration. The main causes of noise are uneven wall thickness of seamless steel pipe and large centrifugal force. On the other hand, in the idler wheel machining process, The center of the bearing holes at both ends deviates greatly from the center of the outer circle,  which will also generate large centrifugal force and abnormal noise.
(2) There is noise when two shafts of belt conveyor coupling have different centers
The abnormal noise produced by the motor at the high-speed end of the belt conveyor driving device and the coupling with the reducer or brake wheel is the same as the rotation frequency of the motor.
When this noise occurs, the position of the belt conveyor motor and reducer should be adjusted in time to avoid the fracture of the reducer input shaft.
(3) belt conveyor reversing drum, driving drum abnormal sound
During normal operation, the noise of the reversing drum and the driving drum is very small. When there is abnormal noise, the bearing is usually damaged. The main reason for the belt conveyor is that the clearance is too large or too small, shaft channeling, oil leakage or poor oil quality, The seal of the bearing end cover is not in place, resulting in bearing wear and temperature rise. At this time, the dew point of the belt conveyor should be eliminated, the lubricating oil should be replaced, and a large number of bearings should be replaced.
(4) Noise of belt conveyor reducer
Belt conveyor reducer abnormal vibration or sound causes include: foot screw loosening, wheel center or wheel screw loosening, gear serious lack of teeth or wear, reducer oil shortage, etc., should be repaired or replaced in time.
(5) Motor noise of belt conveyor
There are several reasons for the abnormal vibration and sound of the belt conveyor motor: the load is too large; Low pressure or two-phase operation; Anchor bolts or wheels are loose; Bearing failure; Motor turns short circuit. The belt conveyor should stop the inspection, reduce the load, check whether the screw is loose, check whether the bearing is damaged.
(6) Noise caused by bearing damage in belt conveyor
The inner bearings of belt conveyors usually need to have stable supporting capacity. Once they receive high pressure, they are easily damaged.
