Description

Technical Field

[0001] The invention relates to the technical field of plastic crushing, in particular to a self-tumbling processing type plastic product crushing device. Background Art

[0002] Plastics are polymer compounds made from monomers through polyaddition or polycondensation reactions. Their deformation resistance is moderate, somewhere between that of fiber and rubber. They are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. The main component of plastic is resin. Resin refers to polymer compounds that have not yet been mixed with various additives. The term originally derived from lipids secreted by plants and animals, such as rosin and shellac. Resin accounts for approximately 40% to 100% of the total weight of plastics. The basic properties of plastics are primarily determined by the nature of the resin, but additives also play an important role. Some plastics, such as plexiglass and polystyrene, are primarily composed of synthetic resins with no or minimal additives. As market demand for plastics grows, plastic waste is also increasing.

[0003] Currently, when plastic products are crushed, multiple plastic products are put into the crushing device at the same time, which easily leads to the accumulation of plastic products at the material guide port, causing the material guide port to be blocked. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A self-tumbling processing type plastic product crushing device includes a material guide component, the material guide component is used for dispersing and feeding plastic products, and the outer surface of the material guide component is fixedly installed with a guide groove;

[0005] A crushing component, which is used for crushing plastic products;

[0006] A discharging assembly is used to discharge the crushed plastic products. A base is fixedly mounted on the bottom of the discharging assembly, and a guide roller is rotatably mounted on the top of the discharging assembly.

[0007] The material guide assembly is fixedly mounted on the top of the discharge assembly through a guide groove, and the guide roller is adapted to the guide groove through the discharge assembly, and the crushing assembly is fixedly mounted inside the discharge assembly;

[0008] The crushing assembly includes side support plates, each of which has two side connecting plates fixedly mounted on its surface. A connecting plate is fixedly mounted between the opposing surfaces of the two side connecting plates, and a rotating roller is rotatably mounted between the opposing surfaces of the side connecting plates. A worker pours plastic products into the guide trough, causing them to contact the guide assembly within the guide trough. The plastic products then fall through the guide assembly onto the crushing assembly, causing the motor to drive the guide rollers and the crushing assembly to rotate and crush the plastic products. The crushed plastic products fall to the bottom of the discharging assembly and are discharged from the discharging assembly along the inclined angle of the bottom of the discharging assembly.

[0009] Preferably, the side connecting plates are fixedly mounted on both sides of the outer surface of the discharge assembly, and each side connecting plate has a triangular plate fixedly mounted on its surface. A crushing roller is rotatably mounted between the opposing surfaces of the triangular plates. The motor output drives the rotating rollers to rotate, which then conveys the plastic products to the surfaces of the crushing rollers, causing the plastic products to be squeezed and crushed by the two sets of crushing rollers. The crushing rollers are configured as a segmented, multi-group structure. When the plastic products come into contact with the crushing rollers, the segmented crushing rollers increase the contact points between the blades and the plastic products, thereby improving the crushing efficiency of the plastic products and preventing excessive wear of the blades caused by long-term operation of the crushing rollers.

[0010] Preferably, the discharging assembly includes a frame, a positioning plate is fixedly mounted on the outer surface of the frame, a mounting block is fixedly mounted on the bottom of the outer surface of the positioning plate, and a rotating rod is fixedly mounted between opposite surfaces of the mounting block.

[0011] Preferably, a fixed plate is fixedly mounted on the outer surface of the rotating rod, a flap is fixedly mounted on the surface of the fixed plate, and an inclined plate is fixedly mounted on the bottom of the frame, the inclined plate is adapted to the flap, and the frame is fixedly mounted on the bottom of the guide groove. After the plastic products are crushed, they fall onto the upper portion of the inclined plate. Since the inclined plate is arranged in an inclined structure, the crushed plastic slides along the inclined plate toward the flap. Since the crushed plastic products contain a large amount of dust, the powder falls onto the inclined plate and slides out along the inclined plate, thereby reducing the range of dust dispersion. After the crushing is completed, the staff pulls the flap, causing the flap to drive the fixed plate to rotate on the rotating rod, thereby collecting the processed plastic products.

[0012] Preferably, the guide groove includes a top frame, a horizontal plate is fixedly installed on the outer surface of the top frame, a curved groove is fixedly installed on the surface of the top frame away from the horizontal plate, a short plate is fixedly installed on the side of the top frame close to the curved groove, and a limiting plate is fixedly installed on the top of the short plate.

[0013] Preferably, the top frame is fixedly mounted on the top of the frame, the guide roller is rotatably mounted inside the curved groove, and the material guide assembly is fixedly mounted above the top frame. A motor drives the guide roller to rotate within the curved groove, while the guide roller rotates below the material guide assembly to guide and convey the plastic products.

[0014] Preferably, the material guide assembly includes two extrusion blocks, a round rod fixedly mounted between opposing surfaces of the two extrusion blocks, and swing frames fixedly mounted on both sides of the outer surfaces of the extrusion blocks. When plastic products are poured into the guide trough, they fall onto the top of the extrusion blocks. The extrusion blocks are made of a deformable material, and after being squeezed, they sag toward the round rods, causing some plastic products to fall from the center of the extrusion blocks onto the top of the crushing assembly.

[0015] Preferably, friction blocks are fixedly mounted on the outer surfaces of the extrusion blocks, and the friction blocks are adapted to the interior of the top frame. A rotating frame is fixedly mounted on the bottom of the extrusion blocks, and the rotating frame is fixedly mounted between opposite surfaces of the top frame.

[0016] Preferably, the swing frame includes two damping rods, each of which is fixedly mounted on the outer surface of the extrusion block. A connecting block is fixedly mounted on the outer surface of the damping rod, a rotating block is rotatably mounted on the surface of the connecting block, a paddle is fixedly mounted between opposite surfaces of the rotating block, and a bending piece is fixedly mounted on the outer surface of the paddle. When multiple plastic products are simultaneously fed in, the plastic raw material slides from both sides of the extrusion block toward one side of the swing frame, squeezing the swing frame. The bending piece and the paddle are pushed and drive the rotating block to rotate on the surface of the connecting block. At this time, the distance between the bending piece and the extrusion block increases, allowing the plastic products to fall from the gap, thereby dispersing the plastic raw material.

[0017] Preferably, a slider is provided inside the bent piece on the side away from the paddle, and the slider is slidably adapted inside the bent piece. A striking block is fixedly mounted on the surface of the slider, and a limit block is fixedly mounted on the surface of the slider away from the striking block. When the paddle drives the bent piece to move, the striking block collides with the inner wall of the top frame. The striking block is made of rubber and generates elasticity when colliding with the top frame, causing the slider to slide inside the bent piece, thereby preventing blockage when multiple plastic products are poured in.

[0018] The present invention provides a self-tumbling plastic product crushing device, which has the following beneficial effects:

[0019] 1. This self-tumbling plastic product crushing device is designed so that the worker pours the plastic products into the guide groove, so that the plastic products come into contact with the guide assembly in the guide groove. At this time, the plastic products fall through the guide assembly to the top of the crushing assembly, so that the motor drives the guide roller and the crushing assembly to rotate to crush the plastic products. The crushed plastic products fall to the bottom of the discharging assembly and are discharged from the discharging assembly along the inclination angle of the bottom of the discharging assembly.

[0020] 2. The self-tumbling processing type plastic product crushing device drives the roller to rotate through the output end of the motor. At this time, the roller transports the plastic products to the surface of the crushing knife roller, so that the plastic products are squeezed and crushed by two groups of crushing knife rollers. The crushing knife rollers are set to a segmented multi-group structure. When the plastic products come into contact with the crushing knife rollers, the segmented crushing knife rollers increase the contact points between the knife surface and the plastic products, thereby improving the crushing efficiency of the plastic products and avoiding excessive wear of the knife surface caused by long-term operation of the crushing knife rollers.

[0021] 3. The self-tumbling processing type plastic product crushing device, after the plastic products are crushed, falls to the top of the inclined plate. Since the inclined plate is set to an inclined structure, the crushed plastic slides along the inclined plate to the side of the flip plate. Since the crushed plastic products contain a lot of dust, the powder falls onto the inclined plate and slides out along the inclined plate, which can reduce the range of dust dispersion. After the crushing is completed, the staff pulls the flip plate, so that the flip plate drives the fixed plate to rotate on the rotating rod, thereby collecting the processed plastic products.

[0022] 4. This self-tumbling processing type plastic product crushing device, when multiple plastic products are put in at the same time, the plastic raw materials slide from both sides of the extrusion block to one side of the swing frame and squeeze the swing frame. The bending piece and the paddle are pushed and drive the rotating block to rotate on the surface of the connecting block. At this time, the distance between the bending piece and the extrusion block becomes larger, so that the plastic products can fall from the gap, so that the plastic raw materials can be dispersed and put in.

[0023] 5. The self-tumbling processing type plastic product crushing device drives the bending piece to move by the dial plate, causing the knocking block to collide with the inner wall of the top frame. The knocking block is made of rubber and generates elasticity when colliding with the top frame, causing the slider to slide inside the bending piece, avoiding blockage when multiple plastic products are poured in.

DETAILED DESCRIPTION

[0034] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0035] The first embodiment, as Figures 1 to 6 As shown, the present invention provides a technical solution: a self-tumbling processing type plastic product crushing device, comprising a material guide component 6, the material guide component 6 is used for dispersing and feeding plastic products, and a guide groove 2 is fixedly installed on the outer surface of the material guide component 6;

[0036] Crushing component 3, the crushing component 3 is used for crushing plastic products;

[0037] A discharging assembly 5 is used to discharge the crushed plastic products. A base 4 is fixedly mounted on the bottom of the discharging assembly 5, and a guide roller 1 is rotatably mounted on the top of the discharging assembly 5;

[0038] The material guide assembly 6 is fixedly mounted on the top of the discharge assembly 5 through the guide groove 2, and the guide roller 1 is adapted to the guide groove 2 through the discharge assembly 5, and the crushing assembly 3 is fixedly mounted inside the discharge assembly 5;

[0039] The crushing assembly 3 includes a side support plate 33, on the surface of which a side connecting plate 32 is fixedly mounted. Two side connecting plates 32 are provided, and a connecting plate 35 is fixedly mounted between the opposing surfaces of the two side connecting plates 32. A rotating roller 34 is rotatably mounted between the opposing surfaces of the side connecting plates 32. A worker pours plastic products into the guide trough 2, causing the plastic products to contact the guide assembly 6 in the guide trough 2. At this time, the plastic products fall through the guide assembly 6 to the top of the crushing assembly 3, causing the motor to drive the guide roller 1 and the crushing assembly 3 to rotate and crush the plastic products. The crushed plastic products fall to the bottom of the discharging assembly 5 and are discharged from the discharging assembly 5 along the inclined angle of the bottom of the discharging assembly 5.

[0040] The side connecting plates 32 are fixedly mounted on both sides of the outer surface of the discharge assembly 5. Triangular plates 31 are fixedly mounted on the surfaces of each side connecting plate 32. Crushing rollers 36 are rotatably mounted between the opposing surfaces of the triangular plates 31. The motor output drives the rotating rollers 34 to rotate. At this time, the rotating rollers 34 convey the plastic products to the surfaces of the crushing rollers 36, causing the plastic products to be squeezed and crushed by the two sets of crushing rollers 36. The crushing rollers 36 are configured as a segmented, multi-group structure. When the plastic products come into contact with the crushing rollers 36, the segmented crushing rollers 36 increase the contact points between the blades and the plastic products, thereby improving the crushing efficiency of the plastic products and preventing excessive wear of the blades of the crushing rollers 36 due to long-term operation.

[0041] The second embodiment, based on the first embodiment, see Figure 5 As shown, the discharging assembly 5 includes a frame 54 , a positioning plate 56 is fixedly mounted on the outer surface of the frame 54 , a mounting block 57 is fixedly mounted on the bottom of the outer surface of the positioning plate 56 , and a rotating rod 51 is fixedly mounted between the opposite surfaces of the mounting block 57 .

[0042] A fixed plate 53 is fixedly mounted on the outer surface of the rotating rod 51, and a flap 52 is fixedly mounted on the surface of the fixed plate 53. An inclined plate 55 is fixedly mounted on the bottom of the frame 54, and the inclined plate 55 is adapted to the flap 52. The frame 54 is fixedly mounted on the bottom of the guide groove 2. After the plastic products are crushed, they fall onto the top of the inclined plate 55. Since the inclined plate 55 is configured as an inclined structure, the crushed plastic slides along the inclined plate 55 toward the flap 52. Since the crushed plastic products contain a large amount of dust, the powder falls onto the inclined plate 55 and slides down the inclined plate 55, which reduces the range of dust dispersion. After the crushing is completed, the staff pulls the flap 52, causing it to drive the fixed plate 53 to rotate on the rotating rod 51, thereby collecting the processed plastic products.

[0043] The third embodiment, based on the first and second embodiments, see Figures 7 to 9 As shown, the guide groove 2 includes a top frame 22, a horizontal plate 21 is fixedly installed on the outer surface of the top frame 22, a curved groove 25 is fixedly installed on the surface of the top frame 22 away from the horizontal plate 21, a short plate 24 is fixedly installed on the side of the top frame 22 close to the curved groove 25, and a limiting plate 23 is fixedly installed on the top of the short plate 24.

[0044] The top frame 22 is fixedly mounted on the top of the frame 54, the guide roller 1 is rotatably mounted inside the curved groove 25, and the material guide assembly 6 is fixedly mounted above the top frame 22. The motor drives the guide roller 1 to rotate in the curved groove 25. At this time, the guide roller 1 rotates below the material guide assembly 6 to guide and convey the plastic products.

[0045] The material guide assembly 6 includes two extrusion blocks 61. A round rod 65 is fixedly mounted between the opposing surfaces of the two extrusion blocks 61. Swinging brackets 62 are fixedly mounted on both sides of the outer surfaces of the extrusion blocks 61. When plastic products are poured into the guide trough 2, they fall onto the top of the extrusion blocks 61. Since the extrusion blocks 61 are made of a deformable material, they are squeezed and dented toward the round rods 65, causing some plastic products to fall from the center of the extrusion blocks 61 onto the top of the crushing assembly 3.

[0046] The outer surface of the extrusion block 61 is fixedly mounted with a friction block 64 , and the friction block 64 is adapted to the interior of the top frame 22 . The bottom of the extrusion block 61 is fixedly mounted with a rotating frame 63 , and the rotating frame 63 is fixedly mounted between opposite surfaces of the top frame 22 .

[0047] The swing frame 62 includes two damping rods 621, each of which is fixedly mounted on the outer surface of the extrusion block 61. A connecting block 622 is fixedly mounted on the outer surface of the damping rod 621. A rotating block 623 is rotatably mounted on the surface of the connecting block 622. A paddle 624 is fixedly mounted between opposing surfaces of the rotating block 623. A bending piece 625 is fixedly mounted on the outer surface of the paddle 624. When multiple plastic products are simultaneously fed in, the plastic raw materials slide from both sides of the extrusion block 61 toward one side of the swing frame 62, squeezing the swing frame 62. The bending piece 625 and the paddle 624 are pushed and drive the rotating block 623 to rotate on the surface of the connecting block 622. At this time, the distance between the bending piece 625 and the extrusion block 61 increases, allowing the plastic products to fall from the gap and the plastic raw materials to be fed in dispersedly.

[0048] A slider 626 extends through the interior of the bent piece 625 on the side away from the paddle 624. The slider 626 slidably fits within the bent piece 625. A striking block 627 is fixedly mounted on the surface of the slider 626. A limit block 628 is fixedly mounted on the surface of the slider 626 on the side away from the striking block 627. When the paddle 624 drives the bent piece 625 to move, the striking block 627 collides with the inner wall of the top frame 22. The striking block 627 is made of rubber and generates elasticity when colliding with the top frame 22, causing the slider 626 to slide within the bent piece 625, thus preventing jamming when multiple plastic products are poured in.

[0049] During use, the staff pours the plastic products into the guide groove 2 so that the plastic products come into contact with the material guide component 6 in the guide groove 2. At this time, the plastic products fall through the material guide component 6 to the top of the crushing component 3, so that the motor drives the guide roller 1 and the crushing component 3 to rotate to crush the plastic products. The crushed plastic products fall to the bottom of the discharging component 5 and are discharged from the discharging component 5 along the inclined angle of the bottom of the discharging component 5.

[0050] The output end of the motor drives the roller 34 to rotate. At this time, the roller 34 conveys the plastic products to the surface of the crushing knife roller 36, so that the plastic products are squeezed and crushed by the two groups of crushing knife rollers 36. The crushing knife rollers 36 are set to a segmented multi-group structure. When the plastic products come into contact with the crushing knife rollers 36, the segmented crushing knife rollers 36 increase the contact points between the knife surface and the plastic products, thereby improving the crushing efficiency of the plastic products and avoiding excessive wear of the knife surface caused by long-term operation of the crushing knife rollers 36.

[0051] After the plastic products are crushed, they fall onto the top of the inclined plate 55. Since the inclined plate 55 is set to an inclined structure, the crushed plastic slides along the inclined plate 55 to the side of the flip plate 52. Since the crushed plastic products contain a large amount of dust, the powder falls onto the inclined plate 55 and slides out along the inclined plate 55, which can reduce the range of dust dispersion. After the crushing is completed, the staff pulls the flip plate 52, so that the flip plate 52 drives the fixed plate 53 to rotate on the rotating rod 51, thereby collecting the processed plastic products.

[0052] The motor drives the guide roller 1 to rotate in the curved groove 25. At this time, the guide roller 1 rotates below the material guide component 6 to guide and transport the plastic products.

[0053] When the plastic product is poured into the guide groove 2, it falls above the extrusion block 61. The extrusion block 61 is made of an easily deformable material and after being squeezed, the extrusion block 61 is concave toward the round rod 65, causing part of the plastic product to fall from the middle of the extrusion block 61 to above the crushing component 3.

[0054] When multiple plastic products are put in at the same time, the plastic raw materials slide from both sides of the extrusion block 61 to one side of the swing frame 62 and squeeze the swing frame 62. The bending piece 625 and the dial plate 624 are pushed and drive the rotating block 623 to rotate on the surface of the connecting block 622. At this time, the distance between the bending piece 625 and the extrusion block 61 becomes larger, so that the plastic products can fall from the gap and the plastic raw materials can be dispersed and put in.

[0055] When the dial plate 624 drives the bending piece 625 to move, the knocking block 627 collides with the inner wall of the top frame 22. The knocking block 627 is made of rubber and generates elasticity when colliding with the top frame 22, causing the slider 626 to slide in the bending piece 625 to avoid blockage when multiple plastic products are poured in.

[0056] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention.
