Description

Technical Field

[0001] The invention relates to the technical field of plastic regeneration and recovery processing, and in particular to an automatic feeding device for plastic regeneration and recovery processing. Background Art

[0002] Plastic recycling is the process of converting waste plastics into reusable materials. Plastic recycling usually includes steps such as collection and classification, cleaning and crushing, melting and regeneration, and reprocessing and molding.

[0003] When crushing plastic, a crusher is used to crush the plastic. Among them, the double-shaft crusher is a common plastic crusher. The double-shaft crusher uses the blades on two relatively rotating shafts to shear, tear and squeeze the material to achieve the purpose of crushing the material. The material is continuously squeezed between the blades and the shaft to further crush and shape.

[0004] In addition, guide plates cooperating with the blades are equidistantly fixedly connected to both sides of the inner wall of the double-shaft crusher casing, so as to prevent the plastic inside the crushing box from being discharged through the opposite side of the cutters on the two shafts, and the guide plates are staggered with the cutters outside the cutter shaft, and the guide plates are usually welded to the inside of the crushing box. When the double-shaft crusher is disassembled and maintained, since multiple guide plates are staggered with multiple cutters, when the cutters are disassembled and maintained, only the cutter shaft inside the crushing box can be disassembled, and then the cutter shaft can be lifted to separate the cutter from the guide plates. However, when the double-shaft crusher is driven, the two shafts are connected by gears so that the two shafts rotate relative to each other, and one of the shafts is connected to the motor, so when disassembling, multiple parts of the shaft need to be disassembled, which reduces the convenience of cutter disassembly and maintenance, and is not convenient for directly sliding and disassembling the cutter outside the shaft.
