Description

Technical Field

[0001] The present invention relates to the technical field of material crushing, in particular to a waste plastic processing and recycling device. Background Art

[0002] Plastic refers to a plastic material with high molecular weight synthetic resin as the main component, with appropriate additives such as plasticizers, stabilizers, antioxidants, flame retardants, colorants, etc., which is processed and formed, or a rigid material formed by curing and cross-linking. For most plastic products, especially those that are used in large quantities at a single use, 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.

[0003] An existing waste plastics processing and recycling device (publication number: CN213919157U) has at least the following drawbacks: The aforementioned patent utilizes two rotating crushing rollers to crush plastic. However, since some waste plastics have smooth surfaces, the crushing rollers have difficulty exerting force on these smooth plastics, making them difficult to crush, thus affecting crushing efficiency. During pulverization, waste plastics are typically crushed into powder or granules. The long-term cutting heat generated by the crushing blades causes the granular plastic powder to adhere to the crushing blades, which over time affects their proper operation. Furthermore, after pulverizing the material in existing pulverizers, some unpulverized material often exits the pulverizer outlet along with the pulverized material, preventing effective separation and resulting in incomplete pulverization.

[0004] Therefore, we have made improvements to this and proposed a waste plastic processing, recycling and regeneration device. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that during crushing, waste plastic powder or granules adhere to the crushing knife, affecting the normal operation of the crushing knife and failing to form effective separation, resulting in incomplete crushing.

[0006] In order to achieve the above-mentioned purpose of the invention, the present invention provides a waste plastic processing, recycling and regeneration device, including a crusher body, a rotating frame is rotatably installed inside the crusher body, a filter assembly is installed on the rotating frame, a crushing assembly is installed in the middle of the crusher body, a cutting assembly is provided on one side of the crushing assembly, and a cleaning assembly is provided on the other side of the crushing assembly. The outer end of the crushing assembly is connected to a first gear, and the first gear and the rotating frame are meshed with a second gear.

[0007] As a further solution of the present invention, the crusher body includes a shell, side panels are connected to both sides of the shell, and a groove is opened in the middle of the shell and the side panels, the rotating frame is rotatably sleeved in the groove, a feed pipe is connected to the top of the side panel, and a baffle is vertically arranged above the interior of the shell, and a discharge pipe is provided at the bottom end of the shell.

[0008] As a further solution of the present invention, the rotating frame includes four connecting rods, and both ends of the four connecting rods are connected to circular rings at the same time. A mounting groove is provided in the middle of the circular ring, and a gear ring is provided on the surface of the circular ring protruding from the crusher body, and the gear ring is engaged with the second gear.

[0009] As a further solution of the present invention, the filter assembly includes six groups of first sieve plates and second sieve plates, and the six groups of the first sieve plates and the second sieve plates are installed in the middle of the rotating frame one positive and one negative at the same time, and the six groups of the first sieve plates and the second sieve plates form a cylindrical shape.

[0010] As a further solution of the present invention, holes are provided on both the first sieve plate and the second sieve plate, and a plurality of blades are installed in the middle of both the first sieve plate and the second sieve plate.

[0011] As a further solution of the present invention, the crushing assembly includes two symmetrical crushing rollers, an air pipe is opened in the middle of the crushing rollers, a fan is connected to the air pipe, and one end of the two crushing rollers is installed with a driven gear, and the two driven gears are meshed and installed.

[0012] As a further solution of the present invention, the crushing roller includes a hollow drum, a circumferential surface of the drum is provided with a plurality of crushing blades, and the crushing blades are provided with ventilation holes, and the ventilation holes are connected to the cavity in the middle of the drum.

[0013] As a further solution of the present invention, the cutting assembly includes a first arc-shaped plate, which is arched and installed on the right side of the crushing assembly, and a groove is provided on the outer side of the first arc-shaped plate, and a first synchronous belt is connected to the inside of the groove. Several synchronous shafts are connected to the inside of the first synchronous belt, and a first synchronous gear is installed at one end of the synchronous shaft, and the first synchronous gear is engaged with the driven gear.

[0014] As a further solution of the present invention, the cleaning assembly includes a second curved plate, a roller is installed inside the second curved plate, a second synchronous belt is sleeved on the roller, bristles are provided on the surface of the second synchronous belt, and a second synchronous gear is installed at one end of the roller, and the second synchronous gear is engaged with the driven gear.

[0015] As a further solution of the present invention, the number of the mounting slots is six, and the mounting slots are adapted to the filter assembly.

[0016] The waste plastic processing and recycling device provided by the present invention has the following beneficial effects: 1. By arranging a cutting component and a cleaning component on both sides of the crushing component respectively, the relative rotation of the cleaning component and the filtering component is used to clean the filtering component, and the powder and debris on the filtering component are swept out, so as to maintain the filtering effect of the filtering component on the crushed fragments. The middle part of the crushing roller is hollowed out and connected to the crushing blade. The plastic is squeezed and crushed by the tip of the crushing blade between the two crushing rollers to complete the cutting of the plastic. The vents on the crushing blade are set to leave a gap between the plastic and the crushing blade after cutting, so as to avoid the plastic and the crushing blade from sticking tightly. The air pipe is connected to the fan to back-blow the plastic powder generated when the crushing roller is cut to prevent the plastic powder from adhering to the surface of the crushing roller, thereby ensuring the crushing effect of the crushing roller and avoiding the loss of plastic powder.

[0017] 2. The fragmented materials are screened through the filtering component, and the small fragments and powder materials in the plastic are screened out through the filtering component. The rotation of the rotating frame and the filtering component drives the large-diameter fragments to roll upward again. When passing through the cutting component, the fragments are further broken under the extrusion and cutting of the first synchronous belt and the blade. As the filtering component rotates, the fragments are brought to the highest point of the crusher body, and the fragments on the filtering component are re-put into the middle of the crushing component at the baffle to continue the crushing of the fragments. This can not only crush the plastic quickly and evenly, but also make the collected plastic particles more uniform in size, solving the problem of uneven volume of crushed plastic powder in existing plastic recycling devices.

[0018] 3. By setting the filter assembly and the rotating frame in one circle of the crushing assembly, the rotating frame is engaged with the second gear, and several filter assemblies are respectively connected to the two ends of the rotating frame. The filter assembly screens and conveys the crushed fragments inside the crusher body. As the filter assembly wears, if any filter assembly is damaged, the filter assembly can be pulled out from the installation slot and replaced without disassembling the machine, saving manpower and material resources.

The outer end of the crushing component 4 is connected to a first gear 7, and the first gear 7 and the rotating frame 2 are meshed and connected to a second gear 8.

[0024] The crusher body 1 includes a shell 11, and side panels 12 are connected to both sides of the shell 11. A groove is opened in the middle of the shell 11 and the side panels 12.

A discharge pipe 15 is provided at the bottom end of the shell 11. Waste plastics are fed into the interior of the shell 11 through the feed pipe 13 to prevent the plastics from splashing and injuring people during crushing. The setting of the baffle 14 facilitates the interception of the rotating filter component 3, intercepts the crushed fragments rolled up on the filter component 3, and re-enters the middle of the two crushing rollers 41 to facilitate the uniform crushing of the crushed fragments.

[0025] The rotating frame 2 includes four connecting rods 21, and both ends of the four connecting rods 21 are connected to circular rings 22 at the same time. A mounting groove 23 is provided in the middle of the circular ring 22, and the circular ring 22 protrudes from the surface of the crusher body 1 and is provided with a gear ring 24. The gear ring 24 is engaged with the second gear 8.

The cutting assembly 5 is installed on one side of the crushing assembly 4, and one side is squeezed by the filtering assembly 3 so that the crushed fragments passing through here are further cut and crushed, and the other side is adjacent to the crushing assembly 4, so that the fragments entering the middle of the crushing assembly 4 and the cutting assembly 5 continue to be crushed, thereby improving the processing efficiency of the device.

[0031] The cleaning component 6 includes a second curved plate 61, a roller 64 is installed inside the second curved plate 61, a second synchronous belt 62 is sleeved on the roller 64, a brush 63 is provided on the surface of the second synchronous belt 62, and a second synchronous gear 65 is installed at one end of the roller 64, the second synchronous gear 65 is engaged with the driven gear 43, the second synchronous belt 62 and the brush 63 rotate with the second synchronous gear 65, and cleans the filter component 3 passing through here to prevent plastic powder and debris from adhering to the filter component 3, thereby ensuring the filtering effect of the filter component 3.

At this time, the crushing component 4 rotates in opposite directions inside the crusher body 1, and the rotating frame 2 and the filtering component 3 rotate counterclockwise inside the crusher body 1; the waste plastic is thrown in from the feed pipe 13, and the plastic enters the shell 11 along the curvature of the feed pipe 13 and is in the middle of the crushing component 4. It is squeezed and crushed by the crushing roller 41 between the two crushing rollers 41, and the plastic is cut by the crushing blade 412 on the crushing roller 41, and as the crushing component 4 rotates, the cut fragments are discharged to the filtering component 3, and the fragmented material is screened by the filtering component 3, and the plastic powder is sieved out through the filtering component 3. The rotation of the rotating frame 2 and the filter assembly 3 drives the large-diameter fragments to roll upward again. When passing through the cutting assembly 5, the fragments are further crushed under the extrusion and cutting of the first synchronous belt 52 and the blade 33, and as the filter assembly 3 rotates, the fragments are brought to the highest point of the crusher body 1, and the fragments on the filter assembly 3 are re-put into the middle of the crushing assembly 4 at the baffle 14 to continue the crushing of the fragments, guiding the diameter of the fragments to pass through the through hole of the filter assembly 3, and the crushing assembly 4 and the inner side surfaces of the cleaning assembly 6 and the cutting assembly 5 continue to squeeze and cut the fragments; at the same time, the movable installation of the rotating frame 2 and the filter assembly 3 makes it possible to remove the filter assembly 3 from the installation slot 23 and replace it if one of the filter assemblies 3 is damaged, without disassembling the machine, saving manpower and material resources.
