Description

Technical Field

[0001] This utility model relates to the technical field of plastic crushing and recycling equipment, specifically a waste plastic crushing, screening and recycling equipment. Background Technology

[0002] Waste plastic recycling is of great significance to environmental protection and resource recycling. With the widespread use of plastic products, large amounts of waste plastic enter the natural environment, causing serious "white pollution" and threatening ecosystems and human health. In the waste plastic recycling process, crushing and recycling equipment plays a crucial role. This equipment breaks large pieces of plastic into smaller particles, facilitating subsequent washing, sorting, and recycling. The crushed plastic particles are easier to transport and store, while improving the quality and utilization rate of recycled plastics. Highly efficient crushing equipment can also process various types of plastics, adapting to different recycling needs and improving overall recycling efficiency.

[0003] In the prior art, such as the waste plastic crusher disclosed in patent number CN118927463B, there is a box, crushing rollers, and a drive structure. Two or more crushing rollers are symmetrically rotated and installed in the box. The crushing rollers are mainly driven to crush the waste plastic introduced into the feed inlet. Although this crushing method is simple, when waste plastics of different sizes are mixed together for crushing, the larger waste plastics will interfere with the crushing of the smaller waste plastics, thereby reducing the efficiency and effect of crushing waste plastics.

[0004] Therefore, there is a need for improved crushing and recycling equipment that can improve the efficiency of crushing and recycling waste plastics. Utility Model Content

[0030] 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.

[0031] Example: This utility model provides a technical solution for a waste plastic crushing, screening, and recycling equipment, such as... Figures 1-6 As shown, it includes a base plate 100, a crushing component 600 disposed on the top surface of the base plate 100, a feeding trough 200 fixed to one side of the crushing component 600, a receiving trough 700 fixed to the other side of the crushing component 600, a conveyor belt 300 disposed inside the feeding trough 200, a first motor 400 fixed to the side wall of the feeding trough 200, and a screening component 500 fixed to the top surface of the feeding trough 200. One end of the first motor 400 is connected to one side of the conveyor belt 300.

[0032] The screening assembly 500 includes a support frame 606 fixed to the top surface of the base plate 100, a crushing box 601 fixed to the top surface of the support frame 606, a box cover 602 hinged to the top surface of the crushing box 601, a first partition 603 fixed inside the crushing box 601, and a first crushing component 607 and a second crushing component 608 disposed inside the crushing box 601.

[0033] The crushing box 601 has openings on both its front and rear walls. The opening on the front wall of the crushing box 601 is located at the top of the feeding trough 200, and the opening on the rear wall of the crushing box 601 is located at the top of the receiving trough 700. The crushing box 601 is divided into a first crushing chamber 604 and a second crushing chamber 605 by a first partition 603. The first crushing component 607 is located inside the first crushing chamber 604, and the second crushing component 608 is located inside the second crushing chamber 605.

[0034] The screening components 500 are spaced apart on the top surface of the conveyor belt 300. The screening components 500 are translational structures. The screening components 500 are pushed by translation so that materials of different sizes can enter the first crushing chamber 604 and the second crushing chamber 605 respectively.

[0035] By providing two crushing chambers inside the crushing box 601, and using the screening assembly 500 to push larger-sized waste plastics to the same side when conveying waste plastics on the conveyor belt 300, larger-sized waste plastics are screened out and conveyed to the first crushing chamber 604 for crushing. Then, the first crushing component 607 and the second crushing component 608 are used to crush the conveyed waste plastics respectively, avoiding the mixing of larger and smaller-sized waste plastics into the first crushing chamber 604 and the second crushing chamber 605 for crushing, thereby ensuring the crushing efficiency and effect of waste plastics.

[0036] like Figures 2-6 As shown, the first crushing component 607 includes a fixing frame 610 fixed to the side wall of the crushing box 601, a second motor 609 fixed to the side wall of the fixing frame 610, a first rotating shaft 612 connected to the rotating end of the second motor 609, a first gear 611 and a first crushing cutter 613 sleeved and fixed to the outer wall of the first rotating shaft 612, a second gear 614 meshing with the first gear 611, a second rotating shaft 615 inserted into the second gear 614, and a second crushing cutter 616 sleeved and fixed to the outer wall of the second rotating shaft 615. One end of the first rotating shaft 612 and one end of the second rotating shaft 615 are rotatably connected to the side wall of the first partition plate. Multiple first crushing cutters 613 and second crushing cutters 616 are provided, and the first crushing cutters 613 and second crushing cutters 616 are arranged alternately.

[0037] Driven by the second motor 609, the first gear 611 and the second gear 614 mesh and drive each other. The first rotating shaft 612 and the second rotating shaft 615 simultaneously drive multiple first crushing blades 613 and second crushing blades 616 to rotate, thus crushing waste plastics.

[0038] Furthermore, the screening assembly 500 includes a fixing plate 501 fixed to the top surface of the feeding trough 200, a pneumatic rod 502 fixed to the top surface of the fixing plate 501, a push plate 505 connected to the telescopic end of the pneumatic rod 502, a distribution plate 507 fixed to the bottom surface of the push plate 505, a first support plate 503 and a second support plate 506 fixed to the top surface of the fixing plate 501, a guide rod 504 connected between the first support plate 503 and the second support plate 506, the guide rod 504 penetrating through the inside of the push plate 505, and the distribution plates 507 spaced apart on the top surface of the conveyor belt 300.

[0039] By using the pneumatic rod 502 to push and pull the push plate 505, the material distribution plate 507 moves horizontally on top of the conveyor belt 300, pushing larger waste plastics to the same side, while smaller waste plastics continue to be conveyed and enter the two crushing chambers respectively. The screening operation is simple and efficient.

[0040] Furthermore, a baffle plate 301 is fixed on the top surface of the conveyor belt 300, and multiple baffle plates 301 are fixed in parallel. By setting baffle plates 301 on the conveyor belt 300, the waste plastic can be driven to tilt upward, ensuring the stability of material conveying. When the pusher plate 505 pushes larger waste plastics to move, the waste plastics are kept in a guiding translation, which improves the stability of pushing and screening.

[0041] like Figures 2-6 As shown, a discharge trough 701 is fixed to one side of the receiving trough 700. The discharge trough 701 has an inclined structure, and the bottom surface inside the crushing box 601 has an inclined structure. A second partition 702 is fixed inside the discharge trough 701, and one side of the second partition 702 is fixedly connected to the side wall of the first partition 603. By setting the inclined discharge trough 701 to be connected to the outlet of the crushing box 601, the crushed waste plastic is introduced into the receiving trough 700, which facilitates the collection and transfer of the crushed waste plastic.

[0042] Furthermore, a limiting plate 704 is fixed to both the inner wall of the receiving trough 700 and the side wall of the second partition plate. A filter plate 703 is inserted between the inner wall of one side of the receiving trough 700 and the side wall of the second partition plate, and the limiting plate 704 is inserted into the side wall of the filter plate 703. By setting the filter plate 703 inside the receiving trough 700, the crushed waste plastic can be further screened, and the fine waste plastic after crushing can be filtered and separated, so that it can be collected and treated in a targeted manner.

[0043] Furthermore, an inclined guide plate 617 is fixed inside the crushing box 601, and the inclined guide plate 617 is disposed on the top of the second crushing component 608; by setting the inclined guide plate 617 on the second crushing component 608, it is convenient to guide smaller waste plastics to the second crushing component 608, and ensure the stability of crushing waste plastics.

[0044] Specifically, waste plastic is guided onto the conveyor belt 300 and placed on the side of the conveyor belt 300 near the second crushing chamber 605. The first motor 400 is started to drive the conveyor belt 300 to rotate and convey. The baffle plate 301 pushes the waste plastic to rise. When it is conveyed to the distribution plate 507, the pneumatic rod 502 is started to pull the push plate 505. The push plate 505 pushes the large-sized waste plastic to the side of the conveyor belt 300 near the first crushing chamber 604.

[0045] As waste plastics are fed into the crushing chamber 601, larger waste plastics enter the first crushing chamber 604, and smaller waste plastics enter the second crushing chamber 605. The first crushing component 607 and the second crushing component 608 crush the incoming waste plastics respectively. The structure of the second crushing component 608 is the same as that of the first crushing component 607, but the diameter of the crushing blades of the second crushing component 608 is smaller than that of the first crushing component 607, which facilitates efficient crushing of smaller waste plastics. The crushed waste plastics slide down the inclined surface at the bottom of the crushing chamber 601 onto the filter plate 703, which further screens the waste plastics, allowing smaller waste plastics to be screened out for separate collection and processing.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
