[0002] Waste plastic recycling refers to the process of recycling and reusing waste plastics using specific recycling technologies. The general process for processing waste plastics involves first crushing the waste plastics into small pieces, and then using a compression device to compress the crushed waste plastics into blocks.
[0003] During the crushing of waste plastics, the small pieces of plastic that are crushed are lightweight and easily overflow from the crushing chamber. The overflowing plastic pollutes the environment and reduces the recycling rate of plastics. Utility Model Content
[0004] This invention provides a compression device for recycling waste plastics, which solves the technical problem of plastic fragments overflowing from the crushing box when the waste plastic compression device is crushing waste plastics.
[0005] To achieve this technical objective, the present invention adopts the following solution: a compression device for recycling waste plastics, comprising a housing, a crushing mechanism, a compression mechanism, and a negative pressure mechanism;
[0006] The container is located on the ground and is used to hold waste plastics to be compressed;

[0008] The compression mechanism is located at the top of the box and is used to compress the waste plastic to be compressed;
[0009] The negative pressure mechanism is located on the side wall of the chamber and is connected to the chamber to provide negative pressure inside the chamber.
[0010] Furthermore, the crushing mechanism includes a crushing box, pipes, crushing rollers, and transmission components;
[0011] The crushing box is located on the side of the box body. The crushing box is connected to the box body through a pipe. A crushing roller is rotatably connected inside the crushing box. Toothed plates corresponding to the crushing roller are fixed on two opposite sides inside the crushing box.
[0012] The transmission assembly is fixed outside the crushing box, and the transmission assembly is connected to the crushing roller.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] 1. The present invention discloses a compression device for recycling waste plastics, which adds a negative pressure mechanism. The negative pressure mechanism can provide negative pressure to the crushing mechanism. Under the drive of the negative pressure, all the crushed plastic fragments enter the compression mechanism from the discharge port of the crushing mechanism, preventing the plastic fragments from overflowing and splashing. This is more environmentally friendly and can also improve the recycling rate of plastics.

The single-toothed roller crushing structure can ensure that waste plastics are completely crushed. Compared with the double-toothed roller structure, the single-toothed roller structure can also reduce some energy consumption. Attached Figure Description

[0026] To fully understand the purpose, features and effects of this utility model, the following specific embodiments will be used to describe this utility model in detail, but this utility model is not limited thereto.
[0027] like Figure 1 , Figure 2 As shown, the present invention provides a compression device for recycling waste plastics, which includes a housing 1, a crushing mechanism 2, a compression mechanism 3 and a negative pressure mechanism 4.
[0028] The container 1 is set on the ground to hold the crushed waste plastic to be compressed and to provide a working space for the compression operation of the waste plastic. If necessary, the container 1 can be fixed to the ground; however, the specific method of fixing is not the subject of this application and will not be described further.
[0029] The crushing mechanism 2 is installed on the side wall of the box 1. The discharge port of the crushing mechanism 2 is connected to the side wall of the box 1. The crushing mechanism 2 is used to crush the waste plastic to be compressed.
[0030] In one embodiment, the crushing mechanism 2 includes a crushing box 21, a pipe 22, a crushing roller 23, and a transmission assembly 24. The crushing box 21 is welded to the side of the box body 1. The discharge port at the bottom of the crushing box 21 is connected to one end of the pipe 22, and the other end of the pipe 22 is connected to the side wall of the box body 1. The crushing roller 23 is rotatably connected to the middle of the crushing box 21 via a bearing, and at least one end of the crushing roller 23 extends out of the crushing box 21 for transmission connection with the transmission assembly 24. The crushing roller 23 extends along the length or width of the crushing box 21. Toothed plates 25 are fixed on both sides of the crushing roller 23, i.e., on the two opposite side walls inside the crushing box 21, and the positions of the toothed plates 25 correspond to the positions of the protruding teeth on the crushing roller 23. The transmission assembly 24 is fixedly disposed outside the crushing box 21 and is transmissionally connected to the crushing roller 23.
[0031] The transmission assembly 24 includes a motor 241 and a right-angle reducer 242. The motor 241 and the right-angle reducer 242 are connected in a transmission manner, and the motor 241 is fixed on the right-angle reducer 242. The right-angle reducer 242 is fixedly installed outside the crushing box 21. The right-angle reducer 242 is also connected in a transmission manner to the crushing roller 23.
[0032] In use, the motor 241 drives the crushing roller 23 to rotate through the right-angle reducer 242. Under the action of the crushing roller 23 and the toothed plate 25, the waste plastic in the crushing box 21 is crushed into plastic fragments.
[0033] A compression mechanism 3 is located at the top of the housing 1 and is used to compress the waste plastic to be compressed. The compression mechanism 3 includes a drive cylinder 31 and a pressure plate 32. The drive cylinder 31 is vertically fixed at the top of the housing 1. The drive cylinder 31 can be located inside or outside the housing 1, which is not limited in this application. The piston rod of the drive cylinder 31 is located inside the housing 1 and can extend and retract along the height of the housing 1. The pressure plate 32 is fixedly installed at the bottom of the piston rod of the drive cylinder 31.
[0034] A negative pressure mechanism 4 is disposed on the side wall of the housing 1 and is connected to the housing 1 to provide negative pressure inside the housing 1. The negative pressure mechanism 4 can be a fan. In this embodiment, the negative pressure mechanism 4 is fixedly disposed on the outer side wall of the housing 1 opposite to the crushing mechanism 2. The air inlet of the negative pressure mechanism 4 is sealed and connected to the side wall of the housing 1. A filter screen 5 is covered at the connection between the negative pressure mechanism 4 and the housing 1, and the filter screen 5 is fixedly connected to the housing 1. Preferably, the filter screen 5 is embedded in the side wall of the housing 1, that is, the filter screen 5 does not protrude from the side wall of the housing 1.
[0035] To facilitate the removal of compressed waste plastic, one side of the container 1 has an open structure, and a baffle 6 is provided at the opening for removable sealing during use. A transport vehicle 7 is installed at the bottom inside the container 1.
[0036] In operation, waste plastic is first poured into the crushing box 21. The negative pressure mechanism 4 and motor 241 are then activated. The motor 241 drives the crushing roller 23 to rotate, crushing the waste plastic into plastic scraps. Under the action of the negative pressure mechanism 4, the plastic scraps enter the box 1 through the pipe 22 and accumulate on the top of the transport vehicle 7. When the plastic scraps accumulate to a certain amount, the drive cylinder 31 is activated, driving the pressure plate 32 to press down and compress the plastic scraps into a cake. After the compression operation is completed, the baffle 6 is opened, the transport vehicle 7 is pulled out, and the compressed waste plastic can be removed from the box 1.
[0037] Obviously, the connection between the housing 1 and the negative pressure mechanism 4, the connection between the housing 1 and the pipe 22, and the connection between the housing 1 and the baffle 6 should all be sealed to prevent air leakage at these connections from affecting the normal operation of the negative pressure mechanism 4.
[0038] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art can make modifications and variations to the present invention. If such modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered as being within the protection scope of the present invention.
