Abstract

The application discloses a special rubber material crushing equipment and relates to the rubber crushing technical field. The non-opposite surface of the side slide plate is an inclined surface which is inclined outward from top to bottom; and the two sides of the scraping cylinder tooth are fixedly provided with side cutting strips. The special rubber material crushing equipment is characterized in that, when the material is crushed, the side slide plate and the side cutting strips are cooperated. For the elastic material which is mixed between the cutters and cannot be cleaned by the pressing cutter strips, the inclined surface of the side slide plate provides a rebound space for the elastic material in the process of the cutter rotation, so that the material in the shearing and extruding state enters the space between the inclined surface of the side slide plate and the cutter, and in the process of the cutter rotation, the material is driven to contact the side cutting strips. The material mixed in the cutter is further crushed and cut by the staggered shearing between the side cutting strips and the cutter, so that the material is prevented from being accumulated in the cutter to cause the material to be blocked in the cutter.

Description

Technical Field

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

[0002] Specialty rubbers are rubber materials that, in contrast to natural rubbers and general synthetic rubbers, are prepared through special chemical structure design or modification processes. They possess properties such as resistance to extreme environments, anti-aging, oil resistance, solvent resistance, high elasticity, and special physical and mechanical properties. For resource recycling, waste rubber products or rubber scraps are usually processed into rubber powder of different particle sizes. The core purpose is to provide qualified raw materials for subsequent reclaimed rubber production, while realizing the resource utilization of waste rubber. Common equipment uses staggered blades on a cutter shaft to shear rubber, breaking it into small pieces or coarse rubber particles. However, during the crushing process, material is prone to jamming between the cutter shafts, affecting the feeding process and reducing the crushing effect. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a special rubber material crushing device, comprising: The crushing chamber provides a place for rubber recycling and crushing, and a base is fixedly installed at the bottom of the crushing chamber, and a motor is installed on the outside of the crushing chamber. A side guide mechanism is installed inside the crushing chamber, and the side guide mechanism is symmetrically installed along the center position of the axis of the crushing chamber; A roller cutter mechanism is installed inside the crushing chamber and located between the side guide mechanisms; The side guide mechanism includes a rotating groove plate. The rotating groove plate has uniformly spaced grooves on one side near the roller cutter mechanism. A fixing strip is fixedly installed at the bottom of the rotating groove plate, and scraper teeth are fixedly installed at the bottom of the fixing strip. The scraper teeth are located below the grooves and correspond one-to-one with each groove. Side sliding plates are slidably installed on both sides of the scraper teeth. A rubber strip is fixedly installed between the side sliding plates, and the non-opposing surfaces of the side sliding plates are inclined surfaces sloping outwards from top to bottom. Side cutting strips are fixedly installed on both sides of the scraper teeth. The side sliding plates and side cutting strips cooperate to crush the material... When processing materials, for elastic materials that are trapped between the blades and cannot be cleared by the pressure strip, the inclined surface of the side slide plate provides a rebound space for the elastic material during the rotation of the blade. This allows the material under shearing and compression to enter the space between the inclined surface of the side slide plate and the blade. During the rotation of the blade, the material is driven to contact the side cutting strip. The material trapped between the side cutting strip and the blade is crushed and cut by the staggered shearing between the side cutting strip and the blade, which avoids large material accumulating between the blades and causing material blockage. Pressure strips are fixedly installed at the bottom of the side slide plate.

[0004] Preferably, the top of the rotating trough plate is provided with a groove, and a guide plate is rotatably installed at the groove of the rotating trough plate. Side baffles are fixedly installed on both sides of the groove of the rotating trough plate. The opposite surfaces of the side baffles are in close contact with the sides of the guide plate. Through the cooperation of the guide plate and the elastic washer ring, when the amount of uncrushed material is large, the weight of the material is transmitted to the elastic washer ring through the guide plate, causing the elastic washer ring to change shape and the guide plate to rotate in the groove of the rotating trough plate, increasing the tilt angle, so that the material moves to the position of the roller cutter mechanism faster. At the same time, the material accumulation space is increased, avoiding the situation where the storage space remains unchanged after a large amount of material accumulates, causing the material to affect the rotation of the cutter of the roller cutter mechanism. An elastic washer ring is fixedly installed between the guide plate and the rotating trough plate.

[0005] Preferably, the roller cutter mechanism includes a drive shaft, which is symmetrically installed along the center of the crushing chamber axis. Both ends of the drive shaft are rotatably connected to the inner wall of the crushing chamber via bearings. One end of one drive shaft is fixedly connected to the output end of a motor. Roller cylinders are fixedly installed on the outer sides of each drive shaft. Through the cooperation of the roller cutter discs and the roller cylinders, the material is sheared and crushed during relative rotation by the staggered arrangement of the roller cutter discs and the continuous contact and compression between them. Simultaneously, during the shearing process, the arc-shaped grooves of the roller cutter discs cooperate with the roller cylinders, creating a gap during the crushing rotation. This allows the sheared material to remain in the gap and be guided downwards, preventing the sheared material from getting stuck between the roller cylinders and causing jamming. Roller discs are fixedly installed on the outer sides of the roller cylinders, and arc-shaped grooves are evenly distributed on the outer sides of the roller discs.

[0006] Preferably, the roller cutter discs are uniformly installed axially on the outer side of the roller cutter cylinder, and the roller cutter discs on the outer sides of different roller cutter cylinders are staggered. The non-arc-shaped grooves on the outer side of the roller cutter discs are tightly fitted to the outer side of the roller cutter cylinder on the other side. The end of the drive shaft away from the motor passes through the crushing chamber and extends to its outer side. Gears are fixedly installed on the end of the drive shaft away from the motor, and the gears mesh with each other. End clamps are installed at both ends of the outer side of the roller cutter cylinder. Through the cooperation of the end clamps with the roller cutter cylinder, the end clamps block the material at both ends of the roller cutter cylinder during the shearing and crushing process, preventing the material from entering the shearing dead angle position at both ends of the roller cutter cylinder, avoiding affecting the crushing, and preventing material accumulation at both ends, which would cause the roller cutter cylinder to be obstructed from rotating. The non-opposing surfaces of the end clamps are fixedly connected to the inner wall of the crushing chamber, and the inner wall of the roller cutter cylinder is rotatably adapted to the inner wall of the end clamps.

[0007] Preferably, the crushing chamber includes a roller cutter chamber, and a bottom guide plate is fixedly installed on the bottom of the inner wall of the roller cutter chamber. The bottom guide plates are symmetrically installed along the center of the axis of the roller cutter chamber and are located directly below the side guide mechanism. A guide groove is formed at the center of the bottom of the roller cutter chamber, and the bottom guide plates are located on both sides of the guide groove. The opposite surfaces of the bottom guide plates are inclined. A guide hopper is fixedly installed at the guide groove at the bottom of the roller cutter chamber. A feed hopper is fixedly installed on the top of the roller cutter chamber, and a top baffle is fixedly installed on the top of the inner wall of the feed hopper. An inclined guide plate is fixedly installed at the bottom of the inner wall of the feeding hopper. The inclined guide plate cooperates with the top baffle. During feeding, the inclined guide plate tilts and allows the material to slide down under its own weight. At the same time, the top baffle and the inclined guide plate block the material splashed by shearing and crushing at the discharge position. The material blocked by the top baffle can fall directly back into the roller cutter chamber or fall on the top of the inclined guide plate and slide down again, preventing the material from splashing out of the equipment and causing danger. The end of the inclined guide plate away from the feeding hopper tilts downward, and the bottom end of the top baffle tilts towards the inclined guide plate.

[0008] This invention provides a special rubber material pulverizing device. It has the following beneficial effects: (I) This special rubber material crushing equipment, through the cooperation of the side slide plate and the side cutting strip, when crushing materials, for elastic materials that are trapped between the blades and cannot be cleared by the pressure strip, during the rotation of the blades, the inclined surface of the side slide plate provides a rebound space for the elastic materials, so that the materials under shear and compression enter the space between the inclined surface of the side slide plate and the blades. During the rotation of the blades, the materials are driven to contact the side cutting strips. The material trapped between the side cutting strips and the blades is crushed and cut by the staggered shearing between the side cutting strips and the blades, avoiding the accumulation of large materials between the blades and the blockage of the blades.

[0009] (II) This special rubber material crushing equipment, through the cooperation of the guide plate and the elastic pad ring, when the amount of uncrushed material is large, the weight of the material is transmitted to the elastic pad ring through the guide plate, causing the elastic pad ring to change shape and the guide plate to rotate in the groove of the rotating plate, increasing the tilt angle, so that the material moves to the position of the roller cutter mechanism faster, and at the same time increasing the material accumulation space, avoiding the situation where the storage space remains unchanged after a large amount of material accumulates, causing the material to affect the rotation of the cutter of the roller cutter mechanism.

[0010] (III) This special rubber material crushing equipment, through the cooperation of the top baffle and the inclined guide plate, allows the material to slide down under its own weight during feeding by utilizing the inclination of the inclined guide plate. At the same time, the top baffle and the inclined guide plate block the material splashed by shearing and crushing at the discharge position. The material blocked by the top baffle can fall directly back into the roller cutter chamber, or fall on the top of the inclined guide plate and slide down again, preventing the material from splashing out of the equipment and causing danger.

[0011] (iv) This special rubber material crushing equipment, through the cooperation of the roller cutter disc and the roller cutter cylinder, utilizes the interlacing of the roller cutter discs and the continuous contact and squeezing between the roller cutter discs and the roller cutter cylinder during the relative rotation process to shear and crush the material. At the same time, during the shearing process, the arc-shaped groove of the roller cutter disc cooperates with the roller cutter cylinder to create a gap during the crushing rotation process, so that the material that has been sheared can be retained in the gap and driven downward to avoid the material being stuck between the roller cutter cylinders and causing material jamming.

[0012] (v) The special rubber material crushing equipment uses end clamps to cooperate with the roller cutter drum. During the shearing and crushing process, the end clamps block the material at both ends of the roller cutter drum, preventing the material from entering the shearing dead corners at both ends of the roller cutter drum. This avoids affecting the crushing process and prevents material from piling up at both ends, which would obstruct the rotation of the roller cutter drum. Attached Figure Description

Detailed Implementation

[0015] 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.

[0016] For the first embodiment, please refer to... Figures 1 to 2 and Figures 5 to 8 The present invention provides a technical solution: A special rubber material crushing device, comprising: Crushing chamber 1 provides a place for rubber recycling and crushing, and a base 5 is fixedly installed at the bottom of crushing chamber 1, and a motor 4 is installed on the outside of crushing chamber 1. Side guide mechanism 3 is installed inside crushing chamber 1 and is symmetrically installed along the center position of the axis of crushing chamber 1; Roller mechanism 2 is installed inside the crushing chamber 1 and located between the side guide mechanisms 3; The side guide mechanism 3 includes a rotating groove plate 304. Grooves are evenly distributed on one side of the rotating groove plate 304 near the roller cutter mechanism 2. A fixing strip 302 is fixedly installed at the bottom of the rotating groove plate 304, and scraper teeth 303 are fixedly installed at the bottom of the fixing strip 302. The scraper teeth 303 are located below the grooves and correspond one-to-one with the grooves. Side slide plates 308 are slidably installed on both sides of the scraper teeth 303. Rubber strips 310 are fixedly installed between the side slide plates 308, and the non-opposing surfaces of the side slide plates 308 are inclined surfaces sloping outwards from top to bottom. When the roller cutter mechanism 2 is working, the cutter rotates and crushes the material. When the material trapped inside the cutter enters between the scraper teeth 303, it is crushed during rotation. First, the rubber strip 310 restricts the side slide plate 308, causing it to drive the pressure strip 309 to press tightly against the blade. The pressure strip 309 cleans the material trapped in the blade. When the pressure strip 309 cannot clean the material smoothly, the material enters between the inclined surface of the side slide plate 308 and the blade under the drive of the blade. The inclined surface of the side slide plate 308 provides space for the trapped elastic material. In conjunction with the side cutting strip 307, when it rotates and intersects with the blade, it cuts the trapped material again, avoiding large pieces of material from getting trapped between the blades. The side cutting strip 307 is fixedly installed on both sides of the scraper tooth 303, and the pressure strip 309 is fixedly installed on the bottom of the side slide plate 308.

[0017] The top of the rotating plate 304 is provided with a groove, and a guide plate 301 is rotatably installed at the groove of the rotating plate 304. Side baffles 306 are fixedly installed on both sides of the groove of the rotating plate 304. The opposite surfaces of the side baffles 306 are tightly fitted with the sides of the guide plate 301. The guide plate 301 guides the uncrushed material inside the crushing chamber 1, causing it to slide along the top of the guide plate 301 towards the position of the roller cutter mechanism 2. At the same time, when the amount of uncrushed material is large, the weight of the material is transmitted to the elastic washer 305 through the guide plate 301, causing the elastic washer 305 to deform and the guide plate 301 to rotate in the groove of the rotating plate 304, increasing the tilt angle, so that the material moves towards the position of the roller cutter mechanism 2 faster, and at the same time increasing the material accumulation space. The elastic washer 305 is fixedly installed between the guide plate 301 and the rotating plate 304.

[0018] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 9 to 10 As shown, the crushing chamber 1 includes a roller cutter chamber 11. A bottom guide plate 16 is fixedly installed on the bottom of the inner wall of the roller cutter chamber 11. The bottom guide plate 16 is symmetrically installed at the center of the axis of the roller cutter chamber 11 and is located directly below the side guide mechanism 3. The roller cutter mechanism 2 and the side guide mechanism 3 are located inside the roller cutter chamber 11. The worker introduces the material to be crushed from the top of the feed chamber 12, so that the material slides down through the gap between the top baffle 15 and the bottom guide plate 16 and enters the interior of the roller cutter chamber 11 for shearing and crushing. At the same time, during the crushing process, the top baffle 15 and the bottom guide plate 16 cooperate to block the material flying up during the shearing and crushing process. A guide groove is opened at the center of the bottom of the roller cutter chamber 11, and the bottom guide plate 16... Located on both sides of the guide groove, the opposite surfaces of the bottom guide plate 16 are inclined surfaces, and a guide hopper 13 is fixedly installed at the bottom of the guide groove of the roller cutter chamber 11. A feed hopper 12 is fixedly installed at the top of the roller cutter chamber 11. A top baffle 15 is fixedly installed at the top of the inner wall of the feed hopper 12, and an inclined guide plate 14 is fixedly installed at the bottom of the inner wall of the feed hopper 12. The material that has been sheared and crushed passes through the roller cutter mechanism 2 and is guided by the inclined surface of the bottom guide plate 16 to guide the material to the guide groove position. The material passes through the guide groove and enters the guide hopper 13, and the crushed material is discharged through the guide hopper 13. The end of the inclined guide plate 14 away from the feed hopper 12 is inclined downward, and the bottom end of the top baffle 15 is inclined to one side of the inclined guide plate 14.

[0019] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 3 to 4As shown, the roller cutter mechanism 2 includes a drive shaft 21, which is symmetrically installed along the center of the axis of the crushing chamber 1. The two ends of the outer side of the drive shaft 21 are rotatably connected to the inner wall of the crushing chamber 1 through bearings. One end of one drive shaft 21 is fixedly connected to the output end of the motor 4. Roller cylinders 24 are fixedly installed on the outer side of the drive shaft 21. During the process of the roller cutter discs 22 interlacing and rotating relative to each other, the arc-shaped grooves of the roller cutter discs 22 are used to shear the material during the interlacing rotation of the roller cutter discs 22. When the arc-shaped grooves rotate and interlac, there is a gap between them and the roller cylinders 24 on the other side, so that the material that has been sheared and crushed can enter the gap position and be driven by the roller cutter discs 22 during the rotation. It is then guided downward with the cooperation of the side guide mechanism 3. The roller cutter discs 22 are fixedly installed on the outer side of the roller cylinders 24. Arc-shaped grooves are evenly arranged on the outer side of the roller cutter discs 22.

[0020] The hobbing discs 22 are evenly installed axially on the outer side of the hobbing cylinders 24, and the hobbing discs 22 on the outer sides of different hobbing cylinders 24 are staggered. The non-arc-shaped grooves on the outer side of the hobbing discs 22 are in close contact with the outer side of the hobbing cylinders 24 on the other side. Through a fixed connection between one of the drive shafts 21 and the output end of the motor 4, the drive shaft 21 is driven to rotate by the motor 4. At the same time, through the meshing of the gears 25 fixedly connected to the end of the drive shaft 21 away from the motor 4, the rotating drive shaft 21 drives the other drive shaft 21 to rotate, thereby driving the hobbing cylinders 24 to rotate. The movement causes the roller cutter cylinders 24 on both sides to drive the roller cutter discs 22 to rotate relative to each other. By utilizing the staggered installation between the roller cutter discs 22 on both sides, and the relative rotation during operation, the material is sheared and crushed. The end of the drive shaft 21 away from the motor 4 passes through the crushing chamber 1 and extends to its outer side. Gears 25 are fixedly installed on the end of the drive shaft 21 away from the motor 4. The gears 25 mesh with each other. End clamping plates 23 are installed on both ends of the outer side of the roller cutter cylinder 24. The non-opposing surfaces of the end clamping plates 23 are fixedly connected to the inner wall of the crushing chamber 1. The inner wall of the roller cutter cylinder 24 and the inner wall of the end clamping plates 23 are rotatably adapted to each other.

[0021] In use, the worker starts the motor 4, which drives the roller cutter mechanism 2 to rotate at high speed inside the crushing chamber 1. Then, the recycled material to be crushed from the special rubber raw material is introduced from the top of the crushing chamber 1. The material then falls under its own gravity and, through the cooperation of the side guide mechanism 3 and the roller cutter mechanism 2, the material is sheared by the staggered cutting of the blades in the roller cutter mechanism 2 as they rotate. The material is then guided to the position of the roller cutter mechanism 2 through the side guide mechanism 3. The material that has been sheared and crushed passes through the roller cutter mechanism 2 and is discharged from the bottom of the crushing chamber 1.

[0022] In the crushing chamber 1, the roller cutter mechanism 2 and the side guide mechanism 3 are located inside the roller cutter chamber 11. The worker introduces the material to be crushed from the top of the feed chamber 12, so that the material slides down through the gap between the top baffle 15 and the bottom guide plate 16 and enters the inside of the roller cutter chamber 11 for shearing and crushing. At the same time, during the crushing process, the top baffle 15 and the bottom guide plate 16 cooperate to block the material flying up during the shearing and crushing process. Meanwhile, the material that has been sheared and crushed passes through the roller cutter mechanism 2 and is guided by the inclined surface of the bottom guide plate 16 to guide the material to the guide groove position. The material passes through the guide groove and enters the guide hopper 13, and the crushed material is discharged through the guide hopper 13.

[0023] In the roller cutter mechanism 2, one of the drive shafts 21 is fixedly connected to the output end of the motor 4, causing the drive shaft 21 to rotate. At the same time, a gear 25 is fixedly connected to the end of the drive shaft 21 away from the motor 4. Through the meshing of the gears 25, the rotating drive shaft 21 drives the other drive shaft 21 to rotate, which in turn drives the roller cutter cylinder 24 to rotate. This causes the roller cutter cylinders 24 on both sides to drive the roller cutter discs 22 to rotate relative to each other. By using the staggered installation of the roller cutter discs 22 on both sides, and their relative rotation during operation, the material is sheared and crushed. During the process of the roller cutter discs 22 staggering and rotating relative to each other, the arc-shaped grooves of the roller cutter discs 22 create gaps with the roller cutter cylinders 24 on the other side. This allows the sheared and crushed material to enter the gap position and be driven by the roller cutter discs 22 during rotation, and then guided downwards in cooperation with the side guide mechanism 3.

[0024] In the side guide mechanism 3, the uncrushed material inside the crushing chamber 1 is guided by the guide plate 301, causing it to slide along the top of the guide plate 301 towards the position of the roller cutter mechanism 2. Simultaneously, when a large amount of uncrushed material accumulates, the weight of the material is transmitted through the guide plate 301 to the elastic washer ring 305, causing the elastic washer ring 305 to deform and the guide plate 301 to rotate within the groove of the rotating chute plate 304, increasing the tilt angle and allowing the material to move towards the position of the roller cutter mechanism 2 more quickly. This also increases the material accumulation space. When the roller cutter mechanism 2 is working, the cutter rotates and crushes the material. When material is trapped inside the cutter... When the material enters between the scraper teeth 303, during rotation, the rubber strip 310 first restricts the side slide plate 308, causing it to drive the pressure strip 309 to adhere tightly to the blade. The pressure strip 309 cleans the material trapped in the blade. When the pressure strip 309 cannot clean the material smoothly, the material enters between the inclined surface of the side slide plate 308 and the blade under the drive of the blade. The inclined surface of the side slide plate 308 provides space for the trapped elastic material, and in conjunction with the side cutting strip 307, when it rotates and intersects with the blade, it cuts the trapped material again, avoiding large pieces of material trapped between the blades.
