Description

Technical Field

[0001] The present application relates to the technical field of plastic product recycling, and specifically discloses a plastic product recycling device. Background Art

[0002] Plastic is a material that is formed by processing plasticity or curing cross-linking with high molecular weight synthetic resin as the main component. Plastic is mainly composed of synthetic resin and various additives, including plasticizers, stabilizers, antioxidants, etc., which together determine the performance and application range of plastic. According to its properties and uses, plastics can be divided into general plastics, engineering plastics and special plastics.

[0003] There are many kinds of common plastic products, which are widely used in all aspects of daily life;

[0004] For example, plastic bottles, plastic basins, plastic bags, etc.

[0005] The recycling of waste plastic products, in terms of stages, includes the crushing, removal and classification of plastic products;

[0006] Our company believes that the crushing of plastic products is the top priority in the recycling of waste plastic products. Therefore, our company has made significant improvements in the crushing of plastic products;

[0007] Among them, China Publication No. CN117484741B discloses a plastic product crushing device, including a motor installed on one side of the top of the base to provide power for crushing; a crushing bin located on one side of the top of the base for crushing plastic; a rotating shaft that runs through the inside of the crushing bin for transmitting power; a second transmission wheel fixed at one end of the rotating shaft for power transmission; an arc-shaped rack plate is fixed to the outside of the second transmission wheel, a screening plate is provided at the bottom end of the inside of the crushing bin, and a slider is provided at one end of the screening plate. The arc-shaped rack plate and the transmission gear provided in the present invention cooperate with each other to squeeze the sliding block to slide inside the sliding groove, and at the same time, the transmission gear rotates, and the sliding block drives the screening plate to rotate. When the arc-shaped rack plate leaves the transmission gear, the screening plate is reset under the action of the reset spring, and the reciprocating motion of the screening plate causes the crushed plastic to shake quickly, making it convenient for the plastic to be unloaded after the crushing is completed;

[0008] The core of the above patent is: to quickly shake the crushed plastic to facilitate the unloading of the crushed plastic, solve the technical problem that the unloading effect is poor, resulting in slow work efficiency and some crushed plastics cannot be unloaded quickly.

[0009] However, there are still many problems in actual use; many plastics in our lives can be recycled and reused, such as polyethylene and polystyrene, but the crushing of such plastics requires the material to be crushed into small particles. The above patent can only achieve rapid plastic feeding, and there is a lack of improvement in the degree of crushing. In view of this, the inventors have invented a plastic product recycling device. Summary of the invention

[0010] The purpose of the present invention is to solve the problem that the degree of crushing of traditional plastic product recycling equipment is insufficient, thereby causing some plastics to be unable to be reused.

[0011] In order to achieve the above object, the present invention provides the following basic scheme
