Description

Technical Field

[0001] This invention relates to the field of pulverization technology, specifically to a pulverization device for special rubber materials. Background Technology

[0002] Reclaimed rubber material crushing refers to the process of physically crushing waste rubber products or rubber scraps into rubber powder of different particle sizes. The core purpose is to provide qualified raw materials for subsequent reclaimed rubber production, while simultaneously realizing the resource utilization of waste rubber. It involves "breaking down" and grinding large, difficult-to-process waste rubber into "rubber powder" that can be further processed. This is a crucial upstream link in the reclaimed rubber industry chain. Common equipment includes rubber shredders, which use staggered blades on a cutter shaft to "shear, compress, and tear" the rubber, breaking it into small pieces or coarse rubber particles. When processing waste rubber, crushing is necessary; therefore, crushing equipment is required.

[0003] Currently, in traditional waste rubber material crushing equipment, materials are easily embedded between the cutter shafts during the crushing process, causing material jamming, which affects the crushing of waste rubber, and in severe cases, structural jamming may occur, reducing the service life of the equipment. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention is implemented through the following technical solution: A special rubber material crushing device, comprising: The machine body, and the outer shell fixedly installed on the top of the machine body, wherein a spiral discharge device is installed at the bottom of the machine body and a feeding mechanism is installed at the top of the outer shell; A crushing mechanism is used to crush waste rubber, and the crushing mechanism is installed in the middle of the internal cavity of the machine. The crushing mechanism includes a power source and a rotating connector. The power source is fixedly installed on the side of the machine body surface, and the rotating connector is fixedly installed on the side of the inner wall of the machine body. A circular roller is rolled between the center of the rotating connector and the inner wall of the machine body. Crushing teeth are fixedly connected to the outer circular surface of the circular roller. A screening component is installed in the middle of the inner cavity of the machine body. By rotating the output end of the power source, the circular roller can be rotated symmetrically, so that the crushing teeth can rotate together with the circular roller. Combined with the fact that the crushing teeth are evenly distributed on the surface of the circular roller, the rubber material can be crushed by the circumferential rotation of the crushing teeth. Furthermore, the crushing teeth are driven to rotate in opposite directions by the symmetrical circular rollers on both sides, which makes the crushing efficiency high and further promotes the crushing of rubber materials. The screening assembly includes a butterfly-shaped substrate, which is fixedly installed in the middle of the inner cavity of the machine. A tip diverter is fixedly connected to the middle of the top of the butterfly-shaped substrate. A strip-shaped perforation is opened at the bottom of the butterfly-shaped substrate. A positive hook-shaped cutting tooth is fixedly connected to the inner side of the butterfly-shaped substrate near the tip diverter. A negative hook-shaped cutting tooth is fixedly connected to the inner side of the butterfly-shaped substrate away from the positive hook-shaped cutting tooth. The grinding teeth are rotated by the roller, so that the grinding teeth pass between two adjacent positive hook-shaped cutting teeth, which can form a scissor-like crushing. As the roller drives the grinding teeth to continue to rotate, the rubber material falling into the bottom of the inner cavity of the butterfly-shaped substrate is lifted by the grinding teeth, and the grinding teeth pass between two adjacent negative hook-shaped cutting teeth again, which can crush the rubber material a second time, so that the rubber material is crushed evenly and large pieces of material are not easily produced.

[0005] Preferably, the outer end of the roller away from the rotating connector is rotatably mounted between the inner wall of the machine body and the outer end of the roller away from the rotating connector. The outer end of the roller extends through the inner wall of the machine body and extends to its outside. The outer end of the roller is fixedly mounted between the output end of the power source and the output end of the power source via a coupling. As the roller drives the crushing teeth to rotate and crush the rubber material, the rubber material is subjected to a downward pulling force. The contact area between the tip of the tip divider and the rubber material decreases, and the pressure increases instantaneously, which can cause the rubber material to be torn by the tip of the tip divider.

[0006] Preferably, there are two rollers, and the two rollers are symmetrically installed along the central axis in the middle of the machine body. The crushing teeth are evenly distributed on the outer surface of the rollers. The positive hook-shaped cutting teeth and the negative hook-shaped cutting teeth are arranged alternately with the crushing teeth. When the roller drives the crushing teeth to rotate and crush the rubber material, the positive hook-shaped cutting teeth and the negative hook-shaped cutting teeth will remove the rubber material stuck between two adjacent crushing teeth, so that there will be no material jamming.

[0007] By using the upward-pointing tip of the diverter to divide the falling rubber material, the material can be split to both sides, preventing the material from being too much or too little on one side.

[0008] Preferably, the tip of the tip diverter faces upward, the strip-shaped drain holes are evenly distributed on the bottom of the butterfly-shaped substrate, and the axis of the roller coincides with the central axis of the inner cavity of the butterfly-shaped substrate.

[0009] Preferably, the positive hook-shaped cutting teeth are evenly distributed on the inner side of the butterfly-shaped substrate, and the negative hook-shaped cutting teeth are evenly distributed on the inner side of the butterfly-shaped substrate and away from the positive hook-shaped cutting teeth. The positive hook-shaped cutting teeth, the negative hook-shaped cutting teeth and the crushing teeth are arranged alternately.

[0010] Preferably, the feeding mechanism includes a feeding hopper and a cylindrical sliding sleeve. The bottom of the feeding hopper is fixedly installed at the middle of the top of the outer shell. The cylindrical sliding sleeve is fixedly installed on the side of the top of the outer shell. A bent connecting rod is slidably installed at the center of the cylindrical sliding sleeve. A guillotine plate is slidably installed at the middle of the top of the feeding hopper. The top of the bent connecting rod is fixedly installed between the top side of the guillotine plate and the top of the feeding hopper. A reset spring is fixedly connected between the side of the guillotine plate surface and the top of the feeding hopper.

[0011] Preferably, the bending connecting rod is installed vertically, the bottom end of the bending connecting rod extends into the interior of the feeding hopper, the bottom end of the guillotine plate extends into the interior of the feeding hopper, and the reset spring is arc-shaped.

[0012] Preferably, a cutting mechanism is installed inside the housing. The cutting mechanism includes an electric telescopic rod and a baffle. The electric telescopic rod is hinged to the side of the inner surface of the housing. The top of the baffle is fixedly installed to the top of the inner cavity of the housing. A swing plate is hinged to the telescopic rod of the electric telescopic rod. The top of the swing plate is hinged to the top of the inner cavity of the housing. A herringbone-shaped cutting blade is fixedly installed on the surface of the swing plate, away from the electric telescopic rod. A pressing tooth is fixedly connected to the top of the surface of the swing plate. A herringbone-shaped notch is formed on the surface of the baffle. Support legs are fixedly connected between the surface of the baffle and the inner wall of the outer shell. By extending the telescopic end of the electric telescopic rod, a pushing force can be applied to the swing plate, causing the swing plate to rotate counterclockwise. The swing plate drives the pressing teeth to rotate counterclockwise as well. The pressing teeth contact the bent end at the bottom of the bending connecting rod, so that the bending connecting rod is subjected to a downward pulling force, which causes the bending connecting rod to move downward and drives the guillotine plate to move downward as well. The reset spring is compressed and undergoes elastic deformation. As the guillotine plate moves downward, it can cut the long strip of ribbon-like rubber material in the hopper to prevent entanglement. Furthermore, as the telescopic end of the electric telescopic rod retracts, it applies a pulling force to the swing plate, causing the swing plate to rotate clockwise to reset. This also drives the pressing teeth to rotate clockwise, thus eliminating the pulling force of the pressing teeth on the bottom of the bending connecting rod. Under the elastic force of the reset spring, the guillotine plate moves upward, facilitating continuous feeding of rubber materials.

[0013] Preferably, the electric telescopic rod is installed at an angle, and the herringbone-shaped cutting blades are evenly distributed on the surface of the swing plate and on the side away from the electric telescopic rod. The extension of the telescopic end of the electric telescopic rod pushes the swing plate, causing the swing plate to drive the herringbone-shaped cutting blades to rotate counterclockwise. With the obstruction of the baffle, the falling rubber material is positioned between the herringbone-shaped cutting blades and the baffle. Under the thrust of the telescopic end of the electric telescopic rod, the herringbone-shaped cutting blades move towards the position close to the herringbone notch, thus cutting the rubber material into small segments for pretreatment.

[0014] Preferably, the herringbone notches are evenly distributed on the surface of the baffle, and there are two support legs, which are symmetrically installed along the central axis of the baffle. As the extension end of the electric telescopic rod pulls the swing plate, the swing plate drives the herringbone cutting blade to rotate clockwise to reset, so that the herringbone cutting blade moves away from the herringbone notch, making it easier for the cut small pieces of rubber material to fall.

[0015] This invention provides a special rubber material pulverizing device. It has the following beneficial effects: I. This special rubber material crushing equipment utilizes the rotation of the power source output end to rotate the circular roller symmetrically, causing the crushing teeth to rotate along with the roller. Combined with the fact that the crushing teeth are evenly distributed on the surface of the roller, the rubber material can be crushed through the circumferential rotation of the crushing teeth. Furthermore, the use of two symmetrically positioned circular rollers to drive the crushing teeth to rotate in opposite directions results in high crushing efficiency and further promotes the crushing of rubber materials.

[0016] II. This special rubber material crushing equipment utilizes crushing teeth that pass between two adjacent positive hook-shaped cutting teeth to form a scissor-like crushing action. As the circular roller drives the crushing teeth to rotate continuously, the rubber material falling into the bottom of the butterfly-shaped substrate is lifted up by the crushing teeth, and the crushing teeth pass between two adjacent negative hook-shaped cutting teeth again, thus crushing the rubber material a second time. This results in uniform crushing of the rubber material and prevents the formation of large pieces of material.

[0017] Third, this special rubber material crushing equipment can divide the falling rubber material by using the upward-pointing tip of the diverter, so that the rubber material is distributed to both sides, making it less likely that there will be too much or too little material on one side.

[0018] IV. This special rubber material crushing equipment, as the circular roller drives the crushing teeth to rotate and crush the rubber material, causes the rubber material to be subjected to a downward pulling force. The contact area between the tip of the tip divider and the rubber material decreases, and the pressure increases instantaneously, which can cause the rubber material to be torn by the tip of the tip divider.

[0019] 5. This special rubber material crushing equipment utilizes the staggered arrangement of positive hook-shaped cutting teeth, negative hook-shaped cutting teeth, and crushing teeth. When the circular roller drives the crushing teeth to rotate and crush the rubber material, the positive hook-shaped cutting teeth and negative hook-shaped cutting teeth will remove the rubber material stuck between two adjacent crushing teeth, preventing material jamming.

[0020] VI. This special rubber material crushing equipment utilizes a swing plate that is pushed to rotate counterclockwise. The swing plate drives the pressing teeth to rotate counterclockwise as well. The pressing teeth contact the bent end at the bottom of the bending connecting rod, causing the bending connecting rod to be pulled downward. This causes the bending connecting rod to move downward, which in turn moves the guillotine plate downward. The reset spring is compressed and undergoes elastic deformation. As the guillotine plate moves downward, it can cut the long strips of ribbon-like rubber material in the hopper, preventing entanglement.

[0021] VII. This special rubber material crushing equipment uses the extension of the electric telescopic rod to push the swing plate, causing the swing plate to drive the herringbone cutting blade to rotate counterclockwise. With the baffle blocking the flow, the falling rubber material is positioned between the herringbone cutting blade and the baffle. Under the thrust of the extension of the electric telescopic rod, the herringbone cutting blade moves closer to the herringbone notch, thus cutting the rubber material into small segments for pretreatment.

[0022] 8. In this special rubber material crushing equipment, as the electric telescopic rod extends and retracts, it pulls the swing plate, which drives the herringbone cutting blade to rotate clockwise to reset. This causes the herringbone cutting blade to move away from the herringbone notch, making it easier for the cut pieces of rubber material to fall. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] For the first embodiment, please refer to... Figure 1-5 The present invention provides a technical solution: A special rubber material crushing device, comprising: The machine body 1 and the outer shell 2 fixedly installed on the top of the machine body 1. A spiral feeder 3 is installed at the bottom of the machine body 1 and a feeding mechanism 4 is installed at the top of the outer shell 2. Crushing mechanism 5 is used to crush waste rubber. Crushing mechanism 5 is installed in the middle of the inner cavity of machine body 1. The crushing mechanism 5 includes a power source 51 and a rotating connector 52. The power source 51 is fixedly installed on the side of the surface of the machine body 1, and the rotating connector 52 is fixedly installed on the side of the inner wall of the machine body 1. A circular roller 53 is rolled between the center of the rotating connector 52 and the inner wall of the machine body 1. Crushing teeth 54 are fixedly connected to the outer circular surface of the circular roller 53. A screening component 55 is installed in the middle of the inner cavity of the machine body 1. When the operator turns on the power source 51, the circular roller 53 can be rotated symmetrically by the rotation of the output end of the power source 51. This allows the crushing teeth 54 to rotate together with the circular roller 53. Since the crushing teeth 54 are evenly distributed on the surface of the circular roller 53, the rubber material can be crushed by the circumferential rotation of the crushing teeth 54. Furthermore, the crushing teeth 54 are rotated in opposite directions by the symmetrical circular rollers 53 on both sides, resulting in high crushing efficiency. The outer end of the roller 53, away from the rotating connector 52, is rotatably mounted between the inner wall of the machine body 1 and the outer end of the roller 53, away from the rotating connector 52, penetrates the inner wall of the machine body 1 and extends to its outer side. The outer end of the roller 53, extending to the outer side of the machine body 1, is fixedly mounted between the output end of the power source 51 and the outer end of the power source 51 via a coupling.

[0027] There are two circular rollers 53, and the two circular rollers 53 are symmetrically installed along the central axis in the middle of the machine body 1. The crushing teeth 54 are evenly distributed on the outer surface of the circular rollers 53.

[0028] The screening assembly 55 includes a butterfly-shaped substrate 551, which is fixedly installed in the middle of the inner cavity of the machine body 1. A tip diverter 552 is fixedly connected to the middle of the top of the butterfly-shaped substrate 551. A strip-shaped perforation 553 is opened at the bottom of the butterfly-shaped substrate 551. A positive hook-shaped cutting tooth 554 is fixedly connected to the inner side of the butterfly-shaped substrate 551 near the tip diverter 552. A reverse hook-shaped cutting tooth is fixedly connected to the inner side of the butterfly-shaped substrate 551 away from the positive hook-shaped cutting tooth 554. The tooth 555, driven by the circular roller 53, rotates the crushing tooth 54, causing the crushing tooth 54 to pass between two adjacent positive hook-shaped cutting teeth 554, thus forming a scissor-like crushing. As the circular roller 53 drives the crushing tooth 54 to continue rotating, the rubber material that has fallen into the bottom of the inner cavity of the butterfly substrate 551 is lifted up by the crushing tooth 54, and the crushing tooth 54 passes between two adjacent negative hook-shaped cutting teeth 555 again, thus crushing the rubber material a second time, making the rubber material crushed evenly.

[0029] The tip of the tip divider 552 faces upward, and the strip-shaped drain holes 553 are evenly distributed at the bottom of the butterfly substrate 551. The axis of the roller 53 coincides with the central axis of the inner cavity of the butterfly substrate 551. As the rubber material falls, the tip of the tip divider 552 faces upward, so that the falling rubber material can be divided to both sides, making it less likely that there will be too much or too little material on one side.

[0030] Positive hook-shaped cutting teeth 554 are evenly distributed on the inner side of the butterfly substrate 551, and negative hook-shaped cutting teeth 555 are evenly distributed on the inner side of the butterfly substrate 551 away from the positive hook-shaped cutting teeth 554. The positive hook-shaped cutting teeth 554, negative hook-shaped cutting teeth 555 and crushing teeth 54 are arranged alternately. As the roller 53 drives the crushing teeth 54 to rotate, the rubber material is crushed, so that the rubber material is subjected to a downward pulling force. The contact area between the tip of the tip diverter 552 and the rubber material decreases, and the pressure increases instantaneously, which can cause the rubber material to be torn by the tip of the tip diverter 552.

[0031] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 1 to 7 As shown: The feeding mechanism 4 includes a feeding hopper 41 and a cylindrical sliding sleeve 42. The bottom of the feeding hopper 41 is fixedly installed at the middle of the top of the outer shell 2. The cylindrical sliding sleeve 42 is fixedly installed on the side of the top of the outer shell 2. A bending connecting rod 43 is slidably installed at the center of the cylindrical sliding sleeve 42. A guillotine plate 44 is slidably installed at the middle of the top of the feeding hopper 41. The top of the bending connecting rod 43 is fixedly installed between the top side of the guillotine plate 44 and the top of the feeding hopper 41. A reset spring strip 45 is fixedly connected between the side of the surface of the guillotine plate 44 and the top of the feeding hopper 41. When the bending connecting rod 43 is subjected to a downward pulling force, the bending connecting rod 43 can move downward, and drive the guillotine plate 44 to move downward together. The reset spring strip 45 is compressed and elastically deformed. As the guillotine plate 44 moves downward, it can cut off the long strip of ribbon-like rubber material in the feeding hopper 41 to avoid entanglement.

[0032] The bending connecting rod 43 is installed vertically, and the bottom end of the bending connecting rod 43 extends into the interior of the feeding hopper 41. The bottom end of the guillotine plate 44 extends into the interior of the feeding hopper 41, and the reset spring bar 45 is arc-shaped.

[0033] The third embodiment is based on the first and second embodiments; please refer to [link / reference]. Figures 1 to 9 As shown: A cutting mechanism 6 is installed inside the outer casing 2. The cutting mechanism 6 includes an electric telescopic rod 61 and a baffle 62. The electric telescopic rod 61 is hinged to the side of the inner side of the outer casing 2. The top of the baffle 62 is fixedly installed to the top of the inner cavity of the outer casing 2. A swing plate 63 is hinged to the telescopic rod of the electric telescopic rod 61. The top of the swing plate 63 is hinged to the top of the inner cavity of the outer casing 2. A herringbone-shaped cutting blade 64 is fixedly installed on the surface of the swing plate 63 away from the electric telescopic rod 61. A pressing tooth 65 is fixedly connected to the top of the surface of the swing plate 63. A herringbone-shaped notch 6 is formed on the surface of the baffle 62. 6. A support leg 67 is fixedly connected between the surface of the baffle 62 and the inner wall of the outer shell 2. The extension of the telescopic end of the electric telescopic rod 61 pushes the swing plate 63, causing the swing plate 63 to drive the herringbone cutting blade 64 to rotate counterclockwise. Under the obstruction of the baffle 62, the falling rubber material is positioned between the herringbone cutting blade 64 and the baffle 62. Under the thrust of the telescopic end of the electric telescopic rod 61, the herringbone cutting blade 64 moves towards the position close to the herringbone notch 66, thus cutting the rubber material into small segments for pretreatment.

[0034] The electric telescopic pole 61 is installed at an angle, and the herringbone-shaped cutting blades 64 are evenly distributed on the surface of the swing plate 63 and on the side away from the electric telescopic pole 61.

[0035] As the telescopic end of the electric telescopic rod 61 pulls the swing plate 63, the swing plate 63 drives the herringbone cutting blade 64 to rotate clockwise to reset, so that the herringbone cutting blade 64 moves away from the herringbone notch 66, making it easier for the cut small pieces of rubber material to fall.

[0036] The herringbone-shaped notches 66 are evenly distributed on the surface of the baffle 62. There are two support legs 67, and the two support legs 67 are symmetrically installed along the central axis in the middle of the baffle 62.

[0037] In use, the operator first puts the rubber material to be crushed into the hopper 41 and starts the electric telescopic rod 61. The extension of the telescopic end of the electric telescopic rod 61 can apply a pushing force to the swing plate 63, causing the swing plate 63 to rotate counterclockwise. The swing plate 63 drives the pressing teeth 65 to rotate counterclockwise as well. The pressing teeth 65 contact the bent end at the bottom of the bending connecting rod 43, so that the bending connecting rod 43 is pulled downward, which can make the bending connecting rod 43 move downward and drive the guillotine plate 44 to move downward as well. The reset spring 45 is compressed and deformed elastically. As the guillotine plate 44 moves downward, the long strip of ribbon-like rubber material in the hopper 41 can be cut off to avoid entanglement. As the telescopic end of the electric telescopic rod 61 retracts, it can apply a pulling force to the swing plate 63, causing the swing plate 63 to rotate clockwise to reset, and drive the pressing tooth 65 to rotate clockwise as well. This will cause the pulling force of the pressing tooth 65 on the bottom of the bending connecting rod 43 to disappear, and under the elastic force of the reset spring 45, the guillotine plate 44 will move upward, thus facilitating the continuous feeding of rubber material. Simultaneously, the extension of the telescopic end of the electric telescopic rod 61 pushes the swing plate 63, causing the swing plate 63 to drive the herringbone cutting blade 64 to rotate counterclockwise. Under the obstruction of the baffle 62, the falling rubber material is positioned between the herringbone cutting blade 64 and the baffle 62. Under the thrust of the telescopic end of the electric telescopic rod 61, the herringbone cutting blade 64 moves closer to the herringbone notch 66, thus cutting the rubber material into small segments for pretreatment. As the telescopic end of the electric telescopic rod 61 pulls the swing plate 63, the swing plate 63 drives the herringbone cutting blade 64 to rotate clockwise to reset, so that the herringbone cutting blade 64 moves away from the herringbone notch 66, making it easier for the cut small pieces of rubber material to fall. Furthermore, by using the upward-pointing tip of the tip diverter 552 to divert the falling rubber material, the rubber material can be distributed to both sides, making it less likely that there will be too much or too little material on one side. When the operator turns on the power source 51, the rotation of the output end of the power source 51 can rotate the circular roller 53 symmetrically, which causes the crushing teeth 54 to rotate together with the circular roller 53. Since the crushing teeth 54 are evenly distributed on the surface of the circular roller 53, the rubber material can be crushed by the circumferential rotation of the crushing teeth 54. Furthermore, the crushing teeth 54 are driven to rotate in opposite directions by the symmetrical circular rollers 53 on both sides, resulting in high crushing efficiency. Moreover, as the circular roller 53 drives the crushing tooth 54 to rotate and crush the rubber material, the rubber material is subjected to a downward pulling force. The contact area between the tip of the tip diverter 552 and the rubber material decreases, and the pressure increases instantaneously, which can cause the rubber material to be torn by the tip of the tip diverter 552. The circular roller 53 drives the crushing teeth 54 to rotate, so that the crushing teeth 54 pass between two adjacent positive hook-shaped cutting teeth 554, which can form a scissor-like crushing. As the circular roller 53 drives the crushing teeth 54 to continue to rotate, the rubber material that has fallen into the bottom of the inner cavity of the butterfly substrate 551 is lifted up by the crushing teeth 54, and the crushing teeth 54 pass between two adjacent negative hook-shaped cutting teeth 555 again, which can crush the rubber material a second time, so that the rubber material is crushed evenly. The crushed granular rubber material flows down through the strip-shaped drain hole 553, while the large pieces of rubber material remain inside the butterfly-shaped substrate 551 and are further crushed. The granular rubber material flowing down through the strip-shaped drain hole 553 falls to the bottom of the inner cavity of the machine body 1 and accumulates, and is discharged by the spiral discharger 3.
