A waste plastic recycling crusher

Abstract

This utility model relates to the field of waste plastic recycling technology, and in particular to a waste plastic recycling crusher. The crusher includes a frame, a crushing chamber mounted on the frame, a feeding hopper mounted above the crushing chamber, a feeding port at the end of the feeding hopper, and multiple baffle components inside the feeding hopper. Waste plastic is added to the crushing chamber through the feeding hopper. The baffles are rotatably connected to the inner wall of the feeding hopper. When the waste plastic enters the feeding hopper from the feeding port, the weight of the plastic pushes the baffles to rotate around a rotating shaft, compressing the springs and allowing the plastic to pass through smoothly. After the plastic passes through, the springs return to their original position, effectively blocking any flying debris during the crushing process. The baffles automatically rotate under pressure to make way, and the springs return the material to their original position after it passes through, ensuring continuous feeding and preventing clogging. This solves the problem of continuous feeding caused by traditional cover plates blocking the material.

[0001] This utility model relates to the field of waste plastic recycling technology, and in particular to a waste plastic recycling crusher. Background Technology

[0002] With the development of industry, the application of plastic products has spread to all areas of industry, agriculture and daily life. The amount of waste plastic products generated worldwide every day is incalculable. In order to save resources and improve the utilization rate of waste plastics, waste plastic buckets are usually crushed and processed into plastic pellets after recycling.

[0003] A waste plastic recycling and crushing device, disclosed in CN217916285U, includes a main body with a protective cover fixedly connected to the top of its outer wall. Sliding plates are slidably connected to the top and bottom front ends of the protective cover, sealing the feed inlet to prevent dust carried by the waste plastic and dust generated after crushing from being discharged. The protective cover effectively prevents the splashing of waste plastic residue during the crushing process. Three crushing rollers crush the waste plastic, and a screen intercepts larger pieces of crushed waste plastic. Currently, existing crushing devices mainly rely on sliding baffles to block splashed debris. When the sliding baffles are in the blocking state, the feed inlet of the crusher is blocked, preventing continuous feeding and affecting overall processing efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology where the feed inlet of the crusher is blocked, resulting in the inability to achieve continuous feeding and affecting the overall processing efficiency. The invention provides a waste plastic recycling crusher that uses a baffle plate to automatically rotate and make way when pressed, and the material returns to its original position with the help of a spring after passing through, thus ensuring continuous feeding and preventing material blockage.

[0005] To achieve the above objectives, this utility model provides a waste plastic recycling crusher, including a frame, a crushing box installed on the frame, a feeding hopper installed above the crushing box, a feeding port provided at the end of the feeding hopper, and multiple baffle components provided inside the feeding hopper; the baffle components include baffle plates, one end of the baffle plates is rotatably connected to the inner wall of the feeding hopper via a rotating shaft, and one side of the baffle plates is connected to the inner wall of the feeding hopper via multiple springs.

[0006] As a further description of the above technical solution: the feeding hopper includes a first hopper body and a second hopper body, the feeding end of the second hopper body is connected to the first hopper body, the discharging end of the second hopper body is connected to the crushing box, and a baffle assembly is installed inside both the first hopper body and the second hopper body.

[0007] As a further description of the above technical solution: the first bucket is horizontal, and the second bucket is vertical.

[0008] As a further description of the above technical solution: one side of the feeding hopper is rotatably connected to the crushing box via a tilting shaft, and the other side of the feeding hopper is connected to the crushing box via a first locking member.

[0009] As a further description of the above technical solution: a cover plate is provided on one side of the crushing box, the lower end of the cover plate is rotatably connected to the crushing box via a hinge, and the upper end of the cover plate is connected to the crushing box via a second locking member.

[0010] As a further description of the above technical solution: the first fastening member includes a first fastening plate, a fixing screw is provided on the first fastening plate, the fixing screw is connected to a second fastening plate through a fixing nut, and the second fastening plate is connected to the feeding hopper.

[0011] As a further description of the above technical solution: the second locking member has the same structure as the first locking member.

[0012] As a further description of the above technical solution: an electromagnet is provided on the crushing box, and a fixing plate adapted to the electromagnet is provided on the feeding hopper.

[0013] As a further description of the above technical solution: a drive unit and a control box are provided on the outside of the crushing box.

[0014] The above technical solution has the following advantages or beneficial effects:

[0015] This invention involves adding waste plastic into the crushing chamber via a feeding hopper. A baffle plate is rotatably connected to the inner wall of the feeding hopper. When the waste plastic enters the feeding hopper from the feeding port, the weight of the plastic pushes the baffle plate to rotate around the rotating shaft, compressing the spring and allowing the plastic to pass through smoothly. After the plastic passes through, the spring returns to its original position, effectively blocking any flying debris during the crushing process. Simultaneously, multiple baffle components work together, and the baffle plate automatically rotates under pressure to make way. After the material passes through, it returns to its original position with the help of the spring, unlike traditional sliding baffles that completely block the feeding port. This ensures continuous feeding, prevents clogging, and solves the problem of continuous feeding caused by the obstruction of traditional cover plates. Attached Figure Description

[0022] 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.

[0023] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] like Figure 1-4 As shown, the present invention discloses a waste plastic recycling crusher, including a frame 1, a crushing box 2 installed on the frame 1, a feeding hopper 3 installed above the crushing box 2, a feeding port 4 provided at the end of the feeding hopper 3, and multiple baffle components 5 provided inside the feeding hopper 3; the baffle components 5 include baffle plates 51, one end of the baffle plates 51 is rotatably connected to the inner wall of the feeding hopper 3 through a rotating shaft 52, and one side of the baffle plates 51 is connected to the inner wall of the feeding hopper 3 through multiple springs 53.

[0025] In the technical solution of this utility model, waste plastic is added into the crushing box 2 through the feeding hopper 3, and crushed by the crushing blades inside the crushing box 2. The baffle plate 51 is rotatably connected to the inner wall of the feeding hopper 3. When the waste plastic enters the feeding hopper 3 from the feeding port 4, the weight of the plastic will push the baffle plate 51 to rotate around the rotating shaft 52, and the spring 53 will be compressed, allowing the plastic to pass through smoothly. After the plastic passes through, the spring 53 returns to its original position, driving the baffle plate 51 back to its initial position. This can effectively block the fragments that may be splashed during the crushing process. At the same time, multiple baffle components 5 work together, and the baffle plate 51 will be automatically rotated to make way under pressure. After the material passes through, it will return to its original position with the help of the spring. Unlike traditional sliding baffles, it will not completely block the feeding port, ensuring continuous feeding and achieving protection against material blockage. This solves the problem of continuous feeding caused by the blocking of traditional cover plates.

[0026] like Figure 1 and Figure 2 As shown, the feeding hopper 3 includes a first hopper body 31 and a second hopper body 32. The feeding end of the second hopper body 32 is connected to the first hopper body 31, and the discharging end of the second hopper body 32 is connected to the crushing box 2. Both the first hopper body 31 and the second hopper body 32 are equipped with a baffle assembly 5. The combination of the first hopper body 31 and the second hopper body 32 allows waste material to be smoothly introduced into the crushing box 2 from above, effectively guiding the material into the crushing box 2 from above, reducing waste or deviation of the material during the conveying process. Furthermore, the baffle assembly 5 installed inside both the first hopper body 31 and the second hopper body 32 further enhances the anti-splashing effect.

[0027] Specifically, the first bucket 31 is horizontal, and the second bucket 32 ​​is vertical.

[0028] like Figure 1 and Figure 2 As shown, one side of the feeding hopper 3 is rotatably connected to the crushing box 2 via a tilting shaft 6, and the other side of the feeding hopper 3 is connected to the crushing box 2 via a first locking member 7. The tilting shaft 6 of the feeding hopper 3 enables rotatable connection with the crushing box 2. When it is necessary to open the feeding hopper 3 for internal cleaning or maintenance, the first locking member 7 can be loosened, and the feeding hopper 3 can be opened by rotating around the tilting shaft 6. The operation is simple and convenient.

[0029] Specifically, the first fastening component 7 includes a first fastening plate 71, on which a fixing screw 72 is provided. The fixing screw 72 is connected to a second fastening plate 74 via a fixing nut 73. The second fastening plate 74 is connected to the feeding hopper 3. The fixing screw 72, which is installed between the first fastening plate 71 and the second fastening plate 74 via the fixing nut 73, facilitates the flipping of the feeding hopper 3 and makes it easy to inspect and maintain the feeding hopper 3.

[0030] like Figure 1 and Figure 4As shown, a cover plate 8 is provided on one side of the crushing box 2. The lower end of the cover plate 8 is rotatably connected to the crushing box 2 via a hinge 9, and the upper end of the cover plate 8 is connected to the crushing box 2 via a second locking member 10. The rotatable connection between the cover plate 8 and the crushing box 2 allows the cover plate 8 to close the side opening of the crushing box 2, facilitating maintenance, cleaning, and other operations inside the crushing box 2. When it needs to be opened, the second locking member 10 can be loosened to rotate around the hinge 9 to open the box.

[0031] The second locking member 10 has the same structure as the first locking member 7.

[0032] like Figure 1 and Figure 4 As shown, an electromagnet 11 is provided on the crushing box 2, and a fixing plate 12 adapted to the electromagnet 11 is provided on the feeding hopper 3; the feeding hopper 3 is doubly fixed by the electromagnet 11 and the fixing plate 12 adsorbing and cooperating, and combined with the first locking part 7, which enhances the stability of the connection between the feeding hopper 3 and the crushing box 2.

[0033] The crushing box 2 is equipped with a drive unit 13 and a control box 14 on its outside. The drive unit 13 drives the crushing blades inside the crushing box 2 to work, and the control box 14 controls the machine to work.

[0034] Working principle: Waste plastic is added into the crushing chamber 2 through the feeding hopper 3. The crushing is carried out by the crushing blades inside the crushing chamber 2. The baffle plate 51 is rotatably connected to the inner wall of the feeding hopper 3. When the waste plastic enters the feeding hopper 3 from the feeding port 4, the weight of the plastic will push the baffle plate 51 to rotate around the rotating shaft 52. The spring 53 is compressed, allowing the plastic to pass through smoothly. After the plastic passes through, the spring 53 returns to its original position, driving the baffle plate 51 back to its initial position. This can effectively block the fragments that may be splashed during the crushing process. At the same time, multiple baffle components 5 work together. The baffle plate 51 will be compressed and automatically rotate to make way. After the material passes through, it will return to its original position with the help of the spring. Unlike traditional sliding baffles, it will not completely block the feeding port, ensuring continuous feeding and achieving protection against material blockage. This solves the problem of continuous feeding caused by the blockage of traditional cover plates.
