Background and main structural implementation elements of the new design of rubber crepe machine. This rubber crepe machine plan touches on the skill range of rubber production equipment, and details efficient crepe machines.

Implementation background:

 

The rubber crepe machine is an extremely important basic machinery in the natural rubber processing process. Its operating characteristics are that the two rollers rotate relative to each other at different speeds. Therefore, when the rubber clumps pass through the crepe machine, they are subjected to strong rolling and shearing effects, not only causing a large amount of dehydration and wrinkling on the surface, but also removing impurities inside the clumps.

 

Key elements for achieving skills in crepe machine:

 

The purpose of this rubber crepe machine plan is to provide an efficient crepe machine that can improve the wrinkling effect of the rubber surface and better supply materials for subsequent dry processes.

To address the aforementioned skill issues, this crepe machine plan adopts the following skill plan:

Efficient rubber crepe machine, including crepe tissue and transport tissue,

The crepe tissue includes a bracket, a * * crepe roll, and a second crepe roll. The * * crepe roll and the second crepe roll pass through the bracket horizontally and are driven by an external motor. The * * crepe roll and the second crepe roll are tangent to each other, and the diameter of the * * crepe roll is greater than that of the second crepe roll. Circular protrusions are uniformly arranged on the * * crepe roll and the second crepe roll,

The transportation organization includes a transportation frame and a transportation belt, which is set on the transportation frame and is vertically set below the * * crepe roll and the second crepe roll.

Furthermore, the diameter of the crepe roll is three times that of the second crepe roll.

Furthermore, the top of the bracket is equipped with a feeding hopper, which is vertically arranged above the * * crepe roll and the second crepe roll.

Furthermore, the feeding hopper is equipped with a * * mixing plate and a second mixing plate. The * * mixing plate and the second mixing plate are separately arranged on the opposite side wall of the feeding hopper, and a feeding port is opened between the * * mixing plate and the second mixing plate.

Furthermore, a waterproof cover is provided on the part where both ends of the crepe roller and the second crepe roller pass through the bracket, which is detachable and set on the bracket.

Furthermore, the upper end of the transport frame is equipped with a support rod, which is equipped with a water spray pipe. The water spray pipe is connected to the external water supply pipe, and a water spray hole is uniformly opened on the water spray pipe. The water spray pipe is vertically arranged above the transport belt, and there are two sets of support rods and water spray pipes.

Compared to existing skills, the planning of this crepe machine has at least one beneficial effect:

1. When in use, open the * * crepe roll, the second crepe roll, and the conveyor belt, and participate in the rubber material from the intersection of the * * crepe roll and the second crepe roll. Then, after passing through the * * crepe roll and the second crepe roll, the crepe material falls off the conveyor belt and is transported to the next process. The * * crepe roll and the second crepe roll are uniformly set with circular protrusions, which can make the rubber surface have a good wrinkling effect and better supply the material for the subsequent dry process.

2. There is a feeding hopper, which is equipped with a * * mixing plate and a second mixing plate, which can slow down the feeding speed, ensure uniform feeding, and thus improve the wrinkling effect.

3. It is equipped with support rods and spray pipes, which are washed with water after the wrinkling to make the rubber surface cleaner.
