Structural Principles

The plastic crusher mainly drives the high-speed rotation of the moving blade disc through an electric motor in the operation principle of the equipment. During the high-speed rotation of the moving blade, it forms a relative motion trend with the fixed blade. The gap formed between the moving blade and the fixed blade causes the plastic to be crushed and cut, thereby crushing large pieces of plastic. The crushed plastic is filtered and outputted through a sieve to filter the size of plastic particles, making the entire processing process convenient and labor-saving. For the processing of lightweight plastic films or woven bags, an integrated fan can be used to drive the directional flow of air inside the machine cavity to reduce discharge resistance and increase equipment output.

Main components

1. Plastic crusher chamber

Made of manganese steel casting (casting or welding according to the model), it has the characteristics of wear resistance and strong impact resistance. The shaft boxes on both sides are processed by the boring machine through integrated assembly, which can effectively ensure the smooth operation of the equipment

Sex.

2. Plastic crusher spindle

The spindle is made of alloy material and processed by precision lathe, which can effectively ensure the accuracy of shaft position and reduce the degree of bearing wear.

3. Plastic crusher chuck

The commonly used types of chuck are welding type and casting type (depending on the specific production needs of the equipment processing industry)

4. Plastic crusher blades

The commonly used materials for blades include: 9crsi, inlaid edge, SK5, T10, 6CrW2Si, Cr12MOV, etc

5. Plastic crusher hopper

Adopting the principle of circular arc design, the feeding port is closed in relative space to prevent materials from returning from the main chamber.

6. Circuit control mechanism (selectively installed according to the configuration of the motor)

The main circuit system of the host is mainly composed of components such as three-phase AC contactors, limit switches, thermal circuit breakers, etc

7. Plastic crusher screen

The plastic crusher screen is mainly made of manganese plates stamped to ensure the wear resistance of the screen

8. Plastic crusher lower body

The lower body of the plastic crusher is mainly used to install the motor and set the discharge direction device, and provide support for the upper body
