[0002] Plastic hollow boards are generally made of environmentally friendly, pollution-free, and recyclable thermoplastic polypropylene (PP) and polyethylene (HDPE) resins and various auxiliary materials. Compared with cardboard structures, hollow boards have advantages such as moisture resistance, corrosion resistance, and lighter weight. Plastic hollow boards are widely used in the packaging industry, advertising decoration, and construction fields.

[0003] In the production of plastic hollow boards, a board pulling machine is used. During the use of the board pulling machine, scrap materials are generated. Therefore, recycling the scrap materials can not only save resources and reduce consumption, but also make greater rational use of the scrap materials. The scrap boards need to be crushed into granules before they can be put into new production and reused. However, the existing equipment usually leaves many large pieces of incompletely crushed scrap materials after crushing the scrap boards, resulting in poor crushing quality and low crushing completion.

[0027] This utility model proposes a waste recycling device 100 for a plate pulling machine.

[0028] Please see Figures 1-4 In one embodiment of this utility model, the waste recycling device 100 for a plate pulling machine includes a housing 10, on which an inlet 11 and an outlet 12 are provided. The housing 10 contains a first crushing structure 20 and a second crushing structure 30. The first crushing structure 20 is located directly below the inlet 11 and is used for the initial crushing of the waste plate. The housing 10 contains a first filter plate 14, which is located below the first crushing structure 20. The second crushing structure 30 is located on one side of the first filter plate 14 and is offset from the inlet 11. The particles formed after being crushed by the first crushing structure 20 pass through the first filter plate 14 and fall from the outlet 12. The particles that are not completely crushed slide down the first filter plate 14 to the second crushing structure 30 for secondary crushing.

[0029] In this embodiment, the waste plate falling from the outlet of the plate pulling machine is placed into the housing 10 through the feed port 11. The first crushing structure 20 crushes the waste plate for the first time. The crushed material falls onto the first filter plate 14, which has several filter holes. The granular material falls directly through the filter holes and then falls out from the discharge port 12. Some large pieces of material that have not been crushed slide down the first filter plate 14 into the second crushing structure 30 for secondary crushing, thereby improving the degree of crushing of the waste plate. After the secondary crushing is completed, the material also falls out from the discharge port 12.

[0030] In one embodiment of the present invention, a partition plate 13 is provided at the bottom of the housing 10, the first crushing structure 20 is located on the left side of the partition plate 13, the second crushing structure 30 is located on the right side of the partition plate 13, and one end of the first filter plate 14 is connected to the inner wall of the housing 10, and the other end is connected to the top of the partition plate 13.

[0031] In this embodiment, the first filter plate 14 is inclined, with the end connected to the housing 10 tilting downwards. It is understood that the inclined arrangement of the first filter plate 14 facilitates the sliding off of large, uncrushed pieces of material; if it were arranged parallel, material would accumulate on the first filter plate 14.

[0032] In one embodiment of the present invention, the first crushing structure 20 includes a first active roller 21 and a first driven roller 22. The first active roller 21 and the first driven roller 22 are arranged side by side in the housing 10, and both the first active roller 21 and the first driven roller 22 are provided with gears 50, which mesh with each other.

[0033] The second crushing structure 30 includes a second active roller 31 and a second driven roller 32. The second active roller 31 and the second driven roller 32 are arranged side by side in the housing 10, and both the second active roller 31 and the second driven roller 32 are provided with gears 50, which mesh with each other.

[0034] In this embodiment, the arc-shaped surfaces of the first driving roller 21 and the first driven roller 22 are provided with a plurality of protrusions 23, and the protrusions 23 on the first driving roller 21 and the first driven roller 22 are staggered to facilitate the crushing of the waste plate. Similarly, the arc-shaped surfaces of the second driving roller 31 and the second driven roller 32 are also provided with a plurality of protrusions 23, and the protrusions 23 on both are staggered to better crush the material.

[0035] The housing 10 is equipped with a drive unit 40, the output end of which is connected to the rotating shaft of the first drive roller 21. The drive unit 40 can be a common stepper motor, which can directly drive the first drive roller 21 to rotate. Since the first drive roller 21 and the first driven roller 22 are connected by gear transmission, the first driven roller 22 also rotates while the drive unit 40 drives the first drive roller 21 to rotate, and the first drive roller 21 and the first driven roller 22 rotate in opposite directions.

[0036] Both the first driving roller 21 and the second driving roller 31 have pulleys 60 on their shafts, and a belt 61 connects the two pulleys 60. By using the pulleys 60 and the belt 61, when the drive member 40 drives the first driving roller 21 to rotate, the belt drive can also drive the second driving roller 31 to rotate. Since the second driving roller 31 and the second driven roller 32 are also connected by gears, their rotation directions are opposite. Combined with the boss 23, this improves material crushing. By using a single drive member 40, both the first crushing structure 20 and the second crushing structure 30 can operate simultaneously, reducing production costs.

[0037] In one embodiment of the present invention, the housing 10 is provided with two conical platforms 16, which are located at the feed inlet 11 and above the first crushing structure 20.

[0038] In this embodiment, by setting two conical platforms 16, when the waste plate is put into the feed inlet 11, the waste plate can fall more accurately into the gap between the first active roller 21 and the first driven roller 22. If the waste plate falls onto the first active roller 21 and the first driven roller 22 and cannot be crushed in time, the first active roller 21 and the first driven roller 22 may collide with the protrusions 23 on them when they rotate, causing the material to be squeezed and fly out. The two conical platforms 16 can make the waste plate fall more accurately into the gap between the first active roller 21 and the first driven roller 22, improving processing efficiency and preventing the material from flying out.

[0039] In one embodiment of the present invention, a second filter plate 15 is provided on the housing 10, and the second filter plate 15 is located below the second crushing structure 30.

[0040] In this embodiment, the second filter plate 15, like the first filter plate 14, is also provided with a number of filter holes, and the second filter plate 15 can be disassembled. When the second crushing structure 30 performs secondary crushing on the material that was not completely crushed in the first crushing, the material formed into particles falls from the filter holes on the second filter plate 15 and then falls out from the discharge port 12. If there are still some larger particles, the second filter plate 15 can be pulled out after the current crushing work is completed, and the remaining large particles can be poured back into the feed port 11 for further crushing.

[0041] Working principle: The waste plate falling from the outlet of the plate pulling machine is put into the housing 10 through the feed port 11. The drive unit 40 is started, which simultaneously drives the first crushing structure 20 and the second crushing structure 30 to operate. The first crushing structure 20 crushes the waste plate for the first time. The crushed material falls onto the first filter plate 14. The material formed into particles directly passes through the first filter plate 14 and falls from the discharge port 12. Some large pieces of material that are not completely crushed slide down the first filter plate 14 into the second crushing structure 30 for secondary crushing, thereby improving the crushing degree of the waste plate and ensuring the crushing quality of the material.

[0042] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
