Belt connection mode of coal mine conveyor belt

1. Mechanical joint connection method

Mechanical joint connection is one of the common connection methods on coal mine conveyor belt. The specific operation method is as follows:

(1) Determine the joint position. First of all, it is necessary to determine the connection position according to the length of the conveyor belt to be connected. Taking the mechanical joint as an example, a rectangular notch is generally dug at the joint position for placing the mechanical joint.

(2) Clean the belt. Clean up the joint, including cleaning the belt, scraping off the old rubber layer and repairing the damaged belt, so as to ensure the connection quality.

(3) Paste the film. Stick the film on the belt at the joint position to ensure that the film and the belt are flat and have good adhesion.

(4) Install the joint. Connect the mechanical joint with the film, and adjust the mechanical dimensions in turn according to the instructions to ensure a firm connection.

2. Hot-pressed joint connection method

Hot-pressing joint connection method refers to sticking hot melt adhesive on the belt and connecting the belt by hot pressing at high temperature. The specific operation method is as follows:

(1) Clean the belt. Cleaning work is needed from the joint position to both ends of the belt, including removing dirt and chips, repairing damaged parts and so on.

(2) gluing. Apply hot melt adhesive evenly to the belt at the joint to ensure firm fitting.

(3) hot pressing connection. Put the joint into a special hot press to hot-press the adhesive layer to make it closely combine with the belt.

Second, the coal mine conveyor belt connection operation matters needing attention

1. Preparation before operation. Before the belt connection operation, it is necessary to carry out careful cleaning work to ensure the belt is clean and tidy, and the abnormal situation should be eliminated in time.

2. Operators must have relevant skills. The belt connection of coal mine conveyor belt can only be carried out after professional training and skill examination. Try to avoid personnel who have not received training or passed the examination to carry out this operation.

3. Operate in strict accordance with the operating procedures. The operation procedures for belt connection of coal mine conveyor belt are very strict, so it is necessary to operate according to the requirements of the procedures, otherwise the quality and safety of the joint may be affected.

4. Pay attention to safety during connection operation. During the connection operation, it is necessary to avoid the rotating parts on the belt and keep a sufficient distance to prevent unnecessary safety accidents.
