Characters of Belt Conveyor Buffer Bed

Characters of Belt Conveyor Buffer Bed

Belt conveyor buffer bed is mainly used in the blanking mouth below the belt guide chute. When the material is discharged, impact force caused by the falling materials can be reduced through elasticity of buffer bed to ensure that belt conveyor can operate normally. Here PK Machinery will introduce the main characteristics of belt conveyor buffer bed to you. 

I. Main features 

1. Smooth UHMW polyethylene surface can make the friction between belt and buffer strips minimize. 

2. The front and rear ends of polyethylene surface becomes into a curved, thus ensuring conveyor belt goes through smoothly. 

3. Each section of the buffer strip is connected by heat vulcanization. 

 

II. Characteristics 

1. No moving spare parts, reducing the daily maintenance cost. 

2. It has large supporting area to make average force, reducing belt slack or damage. 

3. It is suitable for various belt and angle and can withstand strong impact. 

4. It can be installed quickly, easy to check and replace. 5. Usually installed on the conveyor belt blanking point, can extend belt lifespan.

Several Ways to Solve Vibration Motor Frequent Trips

Several Ways to Solve Vibration Motor Frequent Trips

Most users know basic operation of the vibration motor. But during operation, there are many notices that we need pay attention, especially the frequent trips of vibration motor. Here PK Machinery will analyze the reasons of frequent trips and how to solve them for your reference: 

1. With regards to vibration motor air switch, if over-current protective device is unconformity, please replace it timely.

2. If motor cable is worn, this is mostly caused by wear and tear over time. Users can wrap it around by adhesive tape. 

3. Bearing is damaged or lack of oil so it will trip due to overload. Then users need to replace bearings timely. 

4. There is something wrong with vibration motor power or breaker aging. 

5. The magnetic circuit performance of the vibration motor declines, resulting in excessive current. 

Above mentioned points are the common reasons, and it is easy to deal with. As long as users find corresponding reasons, then adopt the corresponding methods, the problems can be resolved. If the vibration motor frequent trips are not caused by the above circumstances, please contact us promptly, our technical engineers will offer the help.

Ways to Judge Whether Roller Bearing is Failure

Ways to Judge Whether Roller Bearing is Failure

As we all know, roller is the main spare parts of belt conveyor, while bearing is precision parts of roller. But in the process of using, bearing is very easy to be damaged. How to avoid its failure? If users can identify whether the bearing is failure or not by not removing inspection, it will improve productivity greatly. 

Firstly, we can judge whether the bearing is faulty or not by sound bearing which requires the operators have a lot of experience. It must go through rigorous training to judge if the sound is produced by bearing. 


Secondly, we can judge it by the temperature of working device, but this method has some limitations. We need to constantly record the temperature changes to judge whether the bearing is failure in the operating conditions. 

Finally, we can judge whether the bearing is fault by dirty situation of lubricant when adding lubricant to bearing. If there are other different things mixed with lubricant, then the bearing must be damaged.

What Factors Lead to Inflexible Rotation of Conveyor Roller

What Factors Lead to Inflexible Rotation of Conveyor Roller

In our daily use of conveyor roller, inflexible rotation phenomenon may occur during the operation, what factors lead to inflexible rotation of conveyor roller? Let’s see the following two parts:

The manufacturing quality of belt conveyor idlers

The manufacturing problems of belt conveyor mainly are bearing lacks of rigidity, difficult to ensure the roller assembly accuracy , which restricts the operation flexibility.

Sealing, lubrication and maintenance

Because of belt conveyor working environment is relatively poor, generally, operation site is full of dust, and the bearing sealing form has big influence on roller operation flexibility. If sealing poor, dirt can easily enter into the bearing inner which causes inflexible rotation; in addition, if bearing grease adopts common calcium base grease ,it is easy to change color and become dry, can't reach a very good lubrication effect.

How to solve inflexible rotation problem of conveyor roller

How to solve inflexible rotation problem of conveyor roller

To ensure accuracy during conveyor roller manufacturing process 
Such as the inner hole precision of punch bearing housing should reach grade 3, dimensional tolerance,coaxial degree and ovality of the pipe body two ends must conform to the national standard,can not exceed the tolerance. 
Sealing and lubrication
in addition to ensure the quality of manufacture, also require better lubrication materials, such as lithium base grease which can improve the bearing lubrication performance, this is very necessary to prolong the service life of roller.
Bearing seat adopts labyrinth seal structure of centripetal ball bearing supporting and plastic sealing ring, which can guarantee reasonable bearing stress of roller during operation,but also ensure good dust prevention effect, small resistance, and convenient installation and easy maintenance, it can effectively reduce the conveyor operation cost at the same time.
