Pull Cord Switch on Belt Conveyor

Do you Know Installation and Adjustment of Pull Cord Switch on Belt Conveyor

Pull Cord Switch is commonly known as "emergency stop switch". When the belt conveyor need downtime, Pull cord switch action will stop the conveyor. Pull cord switch can be divided into manual reset and automatic reset. Automatic reset: after action, it can automatically return to the initial position, may lead to error start. Manual reset: after action, the self-locking device can maintain the operating position, it need to manually reset handle to make its return to the initial position.

Pull Cord Switch should be installed on both sides of the conveyor where has a maintenance channel, installation position should ensure that the maintenance person operates conveniently in the event of an emergency.

1.Pull Cord Switch is fixed on the rack.

2.The distance of the two switches on one side is about 50 m, the two switches are connected by the diameter 4mm of wirerope, elastic should be moderate.

3.To reduce the influence of the weight of wire rope on switches, we install supporting ring on the frame every 3 m to support the steel wire rope.

4.The other end of the rope is in tension spring (with rope buckle), In a way not affecting the normal use, using tightener to pull the rope tension on both sides, and to ensure that tension is balanced on both sides.

(Note: The climbing section of the conveyor, should try to shorten the Switch spacing distance and the pull rope length.)

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.

Why will Belt Conveyor Motorized Pulley Get Rusty

Why will Belt Conveyor Motorized Pulley Get Rusty

Motorized Pulley plays an important role during operating belt coveyor. It is source of power and the belt conveyor cannot operate without it. Today, PK Machinery will list some reasons why motorized pulley of belt conveyor will rust.

During the operation process of belt conveyor, it will occur some problems due to incorrect method of using or wear and tear, therefore, we need to know some knowledge in order to ensure the normal operation. Here PK Machinery will list some reasons why motorized pulley of belt conveyor will rust:

1. Electroplating time is not enough, it dues to the problem of process flow;

2. Air liquidity of the location where motorized pulley stores is not good, or the location is wet, it is may due to the large difference in temperature;

3. If the package sealing breaks, the motorized pulley may oxidate and get rusty;

4. The most important point is that before electroplating, the dirt on motorized pulley surface is not being cleaned well, it is also one of the reasons why the motorized pulley will get rusty.
