[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] A crusher for recycling plastic products includes: a positioning base plate 1, on the top of which a cylinder 2 is fixedly connected by a support frame. The inside of the cylinder 2 is a crushing component 3 for crushing plastic film. By setting the positioning base plate 1, a stable support foundation is provided for the entire crusher, ensuring that the equipment will not be displaced due to vibration during operation, thereby enhancing the stability and safety of the equipment.

[0027] The discharge pipe 4 is fixedly connected to the bottom of the cylinder 2. The bottom of the discharge pipe 4 is connected to a screw feeding assembly 5 for conveying the crushed plastic film. The discharge pipe 4 allows the crushed plastic film to be smoothly discharged from the cylinder 2. By connecting the discharge pipe 4 to the screw feeding assembly 5, the automatic conveying of the crushed material is realized, thereby improving the material conveying efficiency.

[0028] The feed inlet of the box 6 is connected to one end of the screw feeding assembly 5. The inside of the box 6 is equipped with a power assembly 7 for compacting the plastic film. The bottom of the box 6 is equipped with a support plate 8. The cylinder 2 and the box 6 are integrated on the positioning base plate. The crushing assembly 3 is installed in the cylinder 2 to crush the plastic film. The crushed plastic film enters the screw feeding assembly 5 through the discharge pipe 4 and is then conveyed to the box 6, where it is compacted by the power assembly 7. This integrated design eliminates the need to transfer the plastic film between different devices during the recycling process, greatly shortening the recycling process, improving the overall recycling efficiency, and reducing time and labor costs. In addition, the compacted plastic film can make full use of the space of transport vehicles and warehouses during transportation and storage, reducing the number of transportation trips and the storage area requirements, thereby reducing transportation and storage costs and improving the economic benefits of enterprises.

[0029] The crushing assembly 3 includes a rotating shaft 301, the top of which is rotatably mounted on the inner top of the cylinder 2. The top of the rotating shaft 301 penetrates the cylinder 2 and is connected to a first drive motor 302. Several sets of blades 303 are fixedly connected to the outer wall of the rotating shaft 301. The first drive motor 302 provides power for the rotation of the rotating shaft 301, driving the blades 303 to rotate at high speed, thus rapidly and efficiently crushing the plastic film. By setting multiple sets of blades 303, the crushing area and crushing force are increased, achieving the effect of improving crushing efficiency and crushing quality, and enabling the plastic film to be fully crushed into small particles that meet the requirements of subsequent processing.

[0030] The spiral feeding assembly 5 includes a connecting pipe 501, the top of which is fixedly connected to the bottom of the discharge pipe 4. A rotating rod 502 is rotatably mounted on the inner wall of the connecting pipe 501. One end of the rotating rod 502 passes through the connecting pipe 501 and is connected to a second drive motor 503. A spiral blade 504 is fixedly connected to the outer wall of the rotating rod 502. The second drive motor 503 drives the rotating rod 502 to rotate, thereby driving the spiral blade 504 to rotate. During rotation, the spiral blade 504 conveys the crushed plastic film from one end of the connecting pipe 501 to the other. By setting the spiral structure of the spiral blade 504, continuous and uniform material conveying is achieved, preventing material blockage, ensuring smooth conveying, and improving the reliability and stability of feeding.

[0031] The power assembly 7 includes an electric push rod 701, which is fixedly installed on the top of the housing 6. One telescopic end of the electric push rod 701 passes through the housing 6 and is fixedly connected to a pressure plate 702. Several sets of guide rods 703 are fixedly connected to the top of the pressure plate 702, and the guide rods 703 are slidably connected to the top of the housing 6. The electric push rod 701 pushes the pressure plate 702 downward to compact the broken plastic film entering the housing 6. The guide rods 703 ensure the stability and verticality of the pressure plate 702 during movement, preventing the pressure plate 702 from shifting. By setting up the combined structure of the electric push rod 701 and the pressure plate 702, the plastic film is effectively compacted, increasing the bulk density of the plastic film and facilitating subsequent transportation and storage.

[0032] A through groove 9 is provided on one side wall of the housing 6. A cover plate 10 is hinged to one side of the housing 6 via the through groove 9. A support plate 8 is inserted into the inner bottom of the housing 6 through the through groove 9. The support plate 8 is used to support the compacted plastic film. When it is necessary to remove the compacted material, the support plate 8 can be pulled out through the through groove 9. The cover plate 10 is designed to prevent material splashing during equipment operation and facilitates the removal of the compacted plastic.

[0033] Positioning blocks 13 are fixedly connected to one side wall of the cover plate 10 and the housing 6, respectively. Positioning pins 14 are inserted into the two sets of positioning blocks 13, securing the cover plate 10 to the housing 6. This ensures that the cover plate 10 will not open arbitrarily during equipment operation. When it is necessary to open the cover plate 10, simply pull out the positioning pins 14. By setting the structure of the positioning blocks 13 and positioning pins 14, the cover plate 10 is reliably positioned and fixed, ensuring the safety and stability of the equipment operation.

[0034] A groove 11 is provided on one side wall of the support plate 8. A pull rod 12 is fixedly connected inside the groove 11. The pull rod 12 provides a point of leverage for the operator, making it convenient for the operator to pull out the support plate 8 through the pull rod 12.

[0035] Working Principle: First, the plastic film to be recycled is put into the cylinder 2. The first drive motor 302 is started, which drives the rotating shaft 301 to rotate. The blades 303 on the rotating shaft 301 crush the plastic film. The crushed plastic film enters the connecting pipe 501 of the screw feeding assembly 5 through the discharge pipe 4. The second drive motor 503 is started, which drives the rotating rod 502 and the screw blades 504 to rotate, conveying the crushed plastic film into the box 6. When a certain amount of crushed plastic film accumulates in the box 6, the electric push rod 701 is started. The electric push rod 701 pushes the pressure plate 702 downward to compact the plastic film. After compaction, the positioning pin 14 is pulled out, the cover plate 10 is opened, and the support plate 8 is pulled out through the pull rod 12 to remove the compacted plastic film. The entire working process, through the coordinated cooperation of various components, realizes the integrated processing of crushing, conveying and compacting of plastic film, improving the efficiency and quality of plastic product recycling and reducing recycling costs.
