Matters needing attention in starting conveyor
First, check before starting the machine.
1. Check the conveyor belt for abnormal wear or damage.
2. The hanging part at the bottom of the conveyor is in a normal position. (Is it abnormal?)
3. Use the conveyor belt tension regulator to check whether the tension of the tension regulator is too large, which shall not exceed the force borne by the conveyor belt (except the pusher conveyor).
4. All backup rollers can rotate smoothly.
5. Whether the wheels are excessively worn.
6. Whether there is any foreign matter between the gear and the embedding part of the conveyor belt must be removed.
7. Whether all supporting slide rails and side guide rails are in excessive or abnormal wear state.
8. Whether the driven shaft and the conveyor belt are completely combined.
9. Whether all lubricating parts are normal.
10, all parts of the conveying system that need to be cleaned.
Second, the importance of cleaning the conveyor
In the process of decontamination and cleaning, corrosive cleaning agents should be avoided to clean the conveyor belt. Although cleaning agent can effectively clean the conveyor belt, it may change the plastic material and affect the service life.
During cleaning, if you want to remove debris and impurities under the conveyor belt or inside the fuselage, please make sure to turn off the machine motor first to avoid injury. Because in many production and transportation processes, dough, syrup product fragments and appearance packaging fragments scattered in the system will cause pollution problems. External pollution, such as dust, sand and broken glass, can pollute the conveying system and cause problems, so daily or regular cleaning is very important. We should always pay attention to the surrounding environment of the conveyor and clean the conveyor system regularly.
Third, maintenance and replacement.
Daily maintenance and replacement are mainly to find the precursor of conveyor failure in advance. Generally, whether to replace it can be determined by visual inspection of its wear degree. Please help you decide or replace it according to the key points (conveyor belt problems and solutions).
Fourth, maintenance
The conveyor belt has a certain life under general use. If it is used for a long time, it will stretch due to normal wear or overload, which will increase the pitch of the conveyor belt; Any of the above reasons will cause the conveyor belt to lose enough function of embedding gears, so it is necessary to repair or replace the conveyor belt.
When the conveyor is running, there will be natural wear between it and the conveyor belt, supporting slide rail and gear. If there is long-term or abnormal friction and wear, it must be replaced to keep the conveyor running smoothly.
Usually, when we replace a new conveyor belt, we should replace the new supporting slide rail and gear together. Ignoring one or more of them will increase the wear and tear of conveyor parts, thus shortening the service life of parts.
Conveyor belts usually only need to replace one or two damaged parts, or parts in a single area. So you just need to remove the damaged part and replace it with a new one.
Common problems of conveying equipment-with teeth
Cause adjustment method
No intermediate gear is fixed between the driving/driven wheels. Re-adjust and fix the intermediate wheel between the driving/driven wheel.
The deviation between the rotating shaft and the running direction of the conveyor belt is too large to form a 90-degree right angle. Adjust the transmission fixing seat so that the driving/driven wheel forms a 90-degree right angle with the center line of the conveyor belt.
The conveyor was hit hard, resulting in tooth jumping. Remove and readjust the conveyor belt.
Excessive gear wear. Replace the gear.
There is a foreign body blocking the connection part of the conveyor belt. Clean the conveyor belt.
The angle of the driving/driven wheel is wrong, or the contact between the lining and the chain plate is not smooth enough. Tilt the contact part between the driving/driven wheel or liner and the chain plate.
Common problems of conveying equipment-tooth jumping
Cause adjustment method
The driving/driven wheel is too close to the chain plate, so that Shuo Shuo can carry out the connection movement. The diameter of a pitch circle is too tight with the fuselage, resulting in jamming. Adjust the most suitable distance between the driving/driven wheel and the chain plate.
The gears other than the middle gear are stuck, so it is impossible to do the deviation movement with adjustable sides. Clean and use blocked gears so that you can move smoothly on both sides.
When the conveyor is extremely full due to power failure or power failure during operation, the motor will start instantly, resulting in overload and destructive tension. Restart the motor after the surface load of the conveyor belt is removed and the conveyor belt is repaired and installed.
There are foreign objects (such as dropped bolts and washers) between the conveyor body and the conveyor belt, resulting in excessive load and destructive tension. Remove foreign objects and readjust the gap between the conveyor belt body and the conveyor belt.
The conveyor belt deviates, causing destructive obstacles during transportation.
Check in detail whether the fuselage structure is abnormally loose, especially the fixing bolts.
The fixing pin falls off, causing the connecting mandrel to protrude from the edge of the conveyor belt and get stuck in the side structure of the fuselage. Replace the damaged parts, reinstall the connecting shaft and fixing pin, and carefully check whether the fuselage structure is abnormally loose.
Common problems of conveying equipment-wear and tear
Cause adjustment method
The conveying fuselage structure has an angular deviation. Adjust the fuselage structure.
The supporting slide rail is not installed at an absolutely parallel angle with the side of the fuselage. Adjust the fuselage structure.
The intermediate gear of the driving/driven wheel is not accurately fixed in the middle of the fuselage. Remove and readjust the fixing device.
The center of the conveyor belt (straight lines at the front and rear ends) is not aligned and coincides with the intermediate gear. Align the adjustment conveyor belt again.
Common problems of conveying equipment-scratches and cuts
Cause adjustment method
A knife edge or groove caused by the surface cutting action of a double-grooved belt. Smooth the surface with fine sandpaper. If the chain plate structure is damaged, please replace it on the spot.
Common problems of conveying equipment-grinding sound
Cause adjustment method
Due to the structural deformation of the conveyor, the gear on the driving/driven wheel shaft cannot be correctly stuck in the conical gap at the bottom of the conveyor belt. Adjust the driving/driven wheel to keep it at a 90-degree right angle with the fuselage.
There are burrs rubbing the fuselage when the new conveyor is injected. Does not affect the running function of the conveyor, and naturally runs smoothly after a period of time. Or adjust that gap between the conveyor belt and the machine body.
The gears and the conveyor belt or the conveyor belt itself are excessively worn. Remove and replace gears and conveyor belts.
No lining was used (wear strip). Add lining.
The fuselage structure is loose. Check the fuselage structure and tighten the screws of all parts.
There is a foreign body blocking the gap in the conveyor belt. Clean it up
Common problems of conveying equipment-friction phenomenon during movement
Cause adjustment method
The distance between the bottom return rollers is too large. Adjust the distance between the return rollers.
If the return suspension is too large, the contact angle between the suspension part and the return roller may be too steep, resulting in obvious pitching motion of the chain plate, and the passive wheel cannot absorb the return tension smoothly, resulting in sudden rubbing. Adjust between return rollers.
The transition angle difference between the driving/driven shaft and the support is too large. Adjust the driving/driven shaft and adjust the belt tensioner.
The return tension of the conveyor belt cannot completely match the internal tension of the load. Adjust the tension properly or increase or decrease the length of the conveyor belt.
