[0002] Waste plastic is a popular term that does not refer to waste, old and useless plastic products. For most plastic products, especially those that are disposable in large quantities, the properties of the plastic material itself do not change significantly after use. Therefore, it is entirely possible to recycle them and reprocess them into plastic products using appropriate methods and then use them again.

[0033] like Figure 1-Figure 5As shown together, this embodiment provides a waste plastic processing and recycling device, which includes a base 1 and a screening assembly 2 arranged on one side of the upper end of the base 1. The upper end of the screening assembly 2 is provided with a crushing assembly 4, and one side of the crushing assembly 4 is provided with a linkage assembly 5.

[0034] The screening assembly 2 includes two sets of fixed plates 21 fixedly arranged symmetrically on the upper end surface of the base 1, a screening plate 22 is inserted into the middle end of the fixed plate 21, and two sets of symmetrical sliding rods 24 are arranged between the two sets of fixed plates 21 and on the upper end of the screening plate 22. The upper ends of the sliding rods 24 are sleeved with two symmetrical sliding sleeves 25, one side of the sliding sleeve 25 is provided with a first spring 26, and the adjacent end of the sliding sleeve 25 is fixedly connected to the crushing box 27;

[0035] The crushing assembly 4 includes a motor 41 fixedly arranged at the upper end of the base 1, a rotating rod 42 is connected to the lower end of the motor 41, a crushing knife 43 is provided at the lower end of the rotating rod 42, a first bevel gear 44 is fixedly sleeved on the outer wall of the rotating rod 42 located at the upper end of the crushing knife 43, a second bevel gear 45 is provided on one side of the first bevel gear 44, and a worm 46 is fixedly connected to the end of the second bevel gear 45 away from the first bevel gear 44;

[0036] The linkage assembly 5 includes a first receiving plate 51 and a second receiving plate 53 fixedly arranged on both sides of the upper end of the base 1. The lower end of the first receiving plate 51 is connected to a worm gear 52, and the lower end of the second receiving plate 53 is connected to a toothless gear 54. The front ends of the worm gear 52 and the toothless gear 54 are both connected to a driving wheel 55. A transmission belt 56 is wrapped around the outer wall of the driving wheel 55, and a tooth plate 57 is provided at the lower end of the toothless gear 54.

[0037] The first bevel gear 44 and the second bevel gear 45 are perpendicular to each other and mesh with each other. The crushing knife 43 is located inside the crushing box 27. The outer wall of the worm 46 is provided with a receiving sleeve 47, and the upper end of the receiving sleeve 47 is fixed to the upper end of the base 1.

[0038] The worm wheel 52 and the toothless gear 54 are rotatably connected to the first receiving plate 51 and the second receiving plate 53 at one end away from the driving wheel 55, respectively. The worm wheel 52 is meshed with the worm 46, and the transmission belt 56 is wound around the outer wall of the driving wheel 55. The gear part of the toothless gear 54 is meshed with the upper end of the tooth plate 57.

[0039] The pushing assembly 6 includes a sleeve rod 61 movably inserted in the middle end of the fixed plate 21, a connecting sleeve 62 is fixedly connected to one side of the sleeve rod 61, a fixing rod 63 is movably inserted in the middle end of the sleeve rod 61 and the connecting sleeve 62, and the end of the fixing rod 63 away from the sleeve rod 61 is fixedly connected to the base 1, and a second spring 64 is movably sleeved on the outer wall of the fixing rod 63, and the two ends of the second spring 64 are respectively fixedly connected to the connecting sleeve 62 and the base 1.

[0040] One end of the sleeve rod 61 away from the connecting sleeve 62 is in contact with the outer wall of the crushing box 27 , and the lower end of the tooth plate 57 is fixedly connected to the upper end of the connecting sleeve 62 .

[0041] The waste plastics that need to be crushed are placed in the crushing box 27, and then the motor 41 is started to drive the rotating rod 42 to rotate. The rotating rod 42 drives the crushing knife 43 to crush the waste plastics in the crushing box 27, and the rotating rod 42 drives the first bevel gear 44 to rotate, and the first bevel gear 44 drives the second bevel gear 45 to rotate, so that the worm 46 rotates along the receiving sleeve 47, and the worm 46 drives the worm wheel 52 to rotate along the first receiving plate 51, so that the driving wheel 55 drives the toothless gear 54 to rotate through the transmission belt 56. Since only a part of the toothless gear 54 has a gear, when the geared part of the toothless gear 54 rotates to engage with the tooth plate 57, the tooth plate 57 moves forward, so that the connecting sleeve 62 slides along the outer wall of the fixed rod 63, and at the same time the connecting sleeve 62 stretches the second spring 64, and the sleeve rod 61 pushes the crushing box 27 to move forward, so that the crushing box 27 drives the four groups of four corners. The sleeve 25 slides along the slide rod 24, the front sleeve 25 compresses the first spring 26, and the rear sleeve 25 stretches the first spring 26. When the gear part of the toothless gear 54 leaves the tooth plate 57, the second spring 64 is retracted under the action of the reverse tension of the second spring 64, so that the sleeve rod 61 gradually moves away from the crushing box 27. Without the pushing force of the sleeve rod 61, the crushing box 27 moves in the opposite direction to the previous one through the reverse force of the first spring 26 until the force of the first springs 26 at both ends is balanced. Therefore, during the startup of the motor 41, the crushing box 27 moves back and forth periodically. Part of the power consumption of the motor 41 is used in the process of the crushing box 27 moving back and forth. The crushing knife 43 can evenly crush the waste plastic in the crushing box 27, reducing unnecessary power consumption, so that a smaller power drive can bring a higher crushing effect.

[0042] like Figure 1-Figure 5 As shown in common, the screening assembly 2 also includes mounting blocks 23 fixedly arranged on both sides of the screening plate 22. A slot matching the mounting block 23 is provided on the inner wall of the fixed plate 21. The sliding sleeve 25 is movably sleeved on the upper end of the outer wall of the slide rod 24. The two ends of the first spring 26 are respectively fixedly connected to the fixed plate 21 and the sliding sleeve 25. The upper end surface of the screening plate 22 is in contact with the lower end surface of the crushing box 27, and the lower end surface of the crushing box 27 can slide along the upper end surface of the screening plate 22.

[0043] A collecting box 3 is movably inserted between the fixed plates 21 and at the lower end of the screening plate 22 . The collecting box 3 is located directly below the screening plate 22 .

[0044] When the crushing box 27 moves back and forth periodically, the lower end of the crushing box 27 can slide along the upper end surface of the screening plate 22, and the screening plate 22 can screen the plastic particles. Plastic particles that meet the size pass through the screening plate 22 and fall to the upper end of the collecting box 3. Larger particles of plastic cannot pass through the screening plate 22 and remain in the crushing box 27 for crushing. After the crushing is completed, the screening plate 22 can be pulled out from the lower end of the fixed plate 21 through the mounting block 23, and the screening plate 22 can be maintained and cleaned to prevent plastic particles from being stuck in the sieve holes and affecting subsequent crushing.

[0045] It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention. In addition, it should be understood that after reading the technical content of the present invention, those skilled in the art may make various changes, modifications and / or variations to the present invention, and all such equivalent forms also fall within the scope of protection defined by the appended claims of this application.
