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 that are polymerized from monomers through addition or condensation reactions. They have a medium resistance to deformation, between fiber and rubber. They are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. The main component of plastics is resin. Resin refers to polymer compounds that have not been mixed with various additives. The term resin was originally named after lipids secreted by animals and plants, such as rosin and shellac. Resin accounts for about 40% to 100% of the total weight of plastics. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. Some plastics are basically composed of synthetic resins and contain no or little additives, such as plexiglass and polystyrene. As the market demand for plastics increases, plastic waste is also increasing.

[0003] At present, 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 and causes 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, comprising 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; A crushing component, which is used for crushing plastic products; A discharging assembly, which is used to discharge the crushed plastic products, wherein 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; The material guide assembly is fixedly mounted on the top of the material discharging assembly through the guide groove, and the guide roller is adapted to the guide groove through the material discharging assembly, and the crushing assembly is fixedly mounted inside the material discharging assembly; The crushing assembly includes a side support plate, a side connecting plate is fixedly installed on the surface of the side support plate, two side connecting plates are provided, a connecting plate is fixedly installed between the opposite surfaces of the two side connecting plates, and a rotating roller is rotatably installed between the opposite surfaces of the side connecting plates. The staff pours the plastic products into the guide groove so that the plastic products contact the guide assembly in the guide groove. At this time, the plastic products fall to the top of the crushing assembly through the guide 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.

[0005] Preferably, the side connecting plates are fixedly mounted on both sides of the outer surface of the discharging assembly, and the surfaces of the side connecting plates are fixedly mounted with triangular plates, and crushing knife rollers are rotatably mounted between the opposite surfaces of the triangular plates. The motor output end drives the rotating roller to rotate, and the rotating roller conveys the plastic products to the surface of the crushing knife roller, so that the plastic products are squeezed and crushed by the two groups of crushing knife rollers. The crushing knife rollers are set as a segmented multi-group structure. When the plastic products contact 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, so as to avoid excessive wear of the knife surface caused by the long-term operation of the crushing knife rollers.

[0006] Preferably, the discharging assembly comprises 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.

[0007] 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, 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 to the top of the inclined plate. Since the inclined plate is set as an inclined structure, the crushed plastic slides along the inclined plate to one side of the flap. 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 dust dispersion range. After the crushing is completed, the staff pulls the flap, so that the flap drives the fixed plate to rotate on the rotating rod, thereby collecting the processed plastic products.

[0008] Preferably, the guide groove includes a top frame, a cross 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 cross 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.

[0009] 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. The motor drives the guide roller to rotate in the curved groove, and the guide roller rotates below the material guide assembly to guide and transport the plastic products.

[0010] Preferably, the material guide assembly includes an extrusion block, two of which are provided, a round rod is fixedly installed between the opposite surfaces of the two extrusion blocks, and swing frames are fixedly installed on both sides of the outer surface of the extrusion block. When the plastic product is poured into the guide groove, it falls above the extrusion block. The extrusion block is made of a deformable material and after being squeezed, the extrusion block is concave toward the round rod, so that part of the plastic product falls from the middle of the extrusion block to the top of the crushing assembly.

[0011] Preferably, a friction block is fixedly mounted on the outer surface of the extrusion block, and the friction block is adapted to the interior of the top frame. A rotating frame is fixedly mounted on the bottom of the extrusion block, and the rotating frame is fixedly mounted between opposite surfaces of the top frame.

[0012] Preferably, the swing frame includes a damping rod, two of which are provided, and both of the damping rods are 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 put in, the plastic raw material slides from both sides of the extrusion block to one side of the swing frame, and the swing frame is extruded, and the bending piece and the paddle are pushed to drive the rotating block to rotate on the surface of the connecting block, and at this time, the distance between the bending piece and the extrusion block becomes larger, so that the plastic products can fall from the spacing, so that the plastic raw materials can be put in dispersedly.

[0013] Preferably, a slider penetrates the inside of the bending piece away from the dial plate, and the slider is slidably adapted inside the bending piece. A knocking block is fixedly installed on the surface of the slider, and a limit block is fixedly installed on the surface of the slider away from the knocking block. When the dial plate drives the bending piece to move, the knocking block collides with the inner wall of the top frame. The knocking block is made of rubber and generates elasticity when colliding with the top frame, so that the slider slides in the bending piece to avoid blockage when multiple plastic products are poured in.

[0014] The present invention provides a self-tumbling processing type plastic product crushing device, which has the following beneficial effects: 1. The self-tumbling processing type plastic product crushing device is configured such that the staff pours the plastic products into the guide groove so that the plastic products come into contact with the material guide assembly in the guide groove. At this time, the plastic products fall through the material 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.

[0015] 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 arranged as a segmented multi-group structure. When the plastic products contact 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, so as to avoid excessive wear of the knife surface caused by long-term operation of the crushing knife rollers.

[0016] 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 arranged as an inclined structure, the crushed plastic slides along the inclined plate to the side of 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, which can reduce the range of dust dispersion. After the crushing is completed, the staff pulls the flap, so that the flap drives the fixed plate to rotate on the rotating rod, thereby collecting the processed plastic products.

[0017] 4. When multiple plastic products are put into the self-tumbling processing type plastic product crushing device 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 to 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.

[0018] 5. The self-tumbling processing type plastic product crushing device drives the bending piece to move by the shifting plate, so that the knocking block collides with the inner wall of the top frame. The knocking block is made of rubber material and generates elasticity when colliding with the top frame, so that the slider slides in the bending piece to avoid blockage when multiple plastic products are poured in.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0022] 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; A crushing component 3, the crushing component 3 is used for crushing plastic products; A discharging assembly 5, which 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; The material guide assembly 6 is fixedly mounted on the top of the material discharging assembly 5 through the guide groove 2, and the guide roller 1 is adapted to the guide groove 2 through the material discharging assembly 5, and the crushing assembly 3 is fixedly mounted inside the material discharging assembly 5; The crushing assembly 3 includes a side support plate 33, a side connecting plate 32 is fixedly installed on the surface of the side support plate 33, two side connecting plates 32 are provided, a connecting plate 35 is fixedly installed between the opposite surfaces of the two side connecting plates 32, and a roller 34 is rotatably installed between the opposite surfaces of the side connecting plates 32. The staff pours the plastic products into the guide groove 2, so that the plastic products contact the guide assembly 6 in the guide groove 2. At this time, the plastic products fall above the crushing assembly 3 through the guide assembly 6, so that the motor drives the guide roller 1 and the crushing assembly 3 to rotate to 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 inclination angle of the bottom of the discharging assembly 5.

[0023] The side connecting plates 32 are fixedly mounted on both sides of the outer surface of the discharging assembly 5, and the surfaces of the side connecting plates 32 are fixedly mounted with triangular plates 31, and crushing knife rollers 36 are rotatably mounted between the opposite surfaces of the triangular plates 31. The output end of the motor drives the rotating rollers 34 to rotate, and at this time, the rotating rollers 34 convey the plastic products to the surface of the crushing knife rollers 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 contact 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, so as to avoid excessive wear of the knife surface caused by the long-term operation of the crushing knife rollers 36.

[0024] The second embodiment is based on the first embodiment. 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 .

[0025] A fixed plate 53 is fixedly mounted on the outer surface of the rotating rod 51, 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, the inclined plate 55 is adapted to the flap 52, and the frame 54 is fixedly mounted on the bottom of the guide groove 2. After the plastic products are crushed, they fall to the top of the inclined plate 55. Since the inclined plate 55 is set as an inclined structure, the crushed plastic slides along the inclined plate 55 to the side of the flap 52. Since the crushed plastic products contain a lot of dust, the powder falls on the inclined plate 55 and slides out along the inclined plate 55 to reduce the dust dispersion range. After the crushing is completed, the staff pulls the flap 52, so that the flap 52 drives the fixed plate 53 to rotate on the rotating rod 51, thereby collecting the processed plastic products.

[0026] The third embodiment is based on the first and second embodiments. Figures 7 to 9As shown, the guide groove 2 includes a top frame 22, a cross 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 cross 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.

[0027] 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, and at this time, the guide roller 1 rotates under the material guide assembly 6 to guide and transport the plastic products.

[0028] The material guide assembly 6 includes an extrusion block 61, two of which are provided, a round rod 65 is fixedly installed between the opposite surfaces of the two extrusion blocks 61, and swing frames 62 are fixedly installed on both sides of the outer surface of the extrusion block 61. 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 a deformable material, and after being squeezed, the extrusion block 61 is concave toward the round rod 65, so that part of the plastic product falls from the middle of the extrusion block 61 to the top of the crushing assembly 3.

[0029] 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 inside 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 the opposite surfaces of the top frame 22 .

[0030] The swing frame 62 includes a damping rod 621, two of which are fixedly mounted on the outer surface of the extrusion block 61, a connection 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 connection block 622, a dial plate 624 is fixedly mounted between the opposite surfaces of the rotating block 623, and a bending piece 625 is fixedly mounted on the outer surface of the dial plate 624. When multiple plastic products are simultaneously put in, the plastic raw material slides from both sides of the extrusion block 61 to one side of the swing frame 62, and the swing frame 62 is squeezed, and the bending piece 625 and the dial plate 624 are pushed to drive the rotating block 623 to rotate on the surface of the connection block 622, and 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 spacing, so that the plastic raw materials can be put in in a dispersed manner.

[0031] A slider 626 is inserted into the inner part of the bending piece 625 away from the dial plate 624. The slider 626 is slidably fitted into the inner part of the bending piece 625. A knocking block 627 is fixedly installed on the surface of the slider 626. A limit block 628 is fixedly installed on the surface of the slider 626 away from the knocking block 627. 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, so that the slider 626 slides in the bending piece 625 to avoid blockage when multiple plastic products are poured in.

[0032] When in use, the staff pours the plastic products into the guide groove 2 so that the plastic products come into contact with the material guiding assembly 6 in the guide groove 2. At this time, the plastic products fall through the material guiding assembly 6 to the top of the crushing assembly 3, so that the motor drives the guide roller 1 and the crushing assembly 3 to rotate to 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 inclination angle of the bottom of the discharging assembly 5.

[0033] The motor output end drives the roller 34 to rotate. At this time, the roller 34 conveys the plastic products to the surface of the crushing roller 36, so that the plastic products are squeezed and crushed by the two groups of crushing rollers 36. The crushing rollers 36 are arranged as a segmented multi-group structure. When the plastic products contact the crushing rollers 36, the segmented crushing rollers 36 increase the contact points between the blade surface and the plastic products, thereby improving the crushing efficiency of the plastic products, so as to avoid excessive wear of the blade surface caused by the long-term operation of the crushing rollers 36.

[0034] After the plastic products are crushed, they fall onto the top of the inclined plate 55. Since the inclined plate 55 is set as an inclined structure, the crushed plastic slides along the inclined plate 55 to the side of the flap 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 flap 52, so that the flap 52 drives the fixed plate 53 to rotate on the rotating rod 51, thereby collecting the processed plastic products.

[0035] 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 transport the plastic products.

[0036] 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 a deformable material and after being squeezed, the extrusion block 61 is recessed toward the round rod 65 , so that part of the plastic product falls from the middle of the extrusion block 61 to above the crushing component 3 .

[0037] 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 to 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.

[0038] 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, so that the slider 626 slides in the bending piece 625 to avoid blockage when multiple plastic products are poured in.

[0039] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
