Description

Technical Field

[0001] The present invention relates to the technical field of recycled rubber processing, and in particular, to a solid waste processing device for recycled rubber. Background Art

[0002] Recycled rubber refers to the materials obtained by recycling and reprocessing waste rubber products and processing them into reusable raw materials or new products, usually including the recycling and treatment processes of waste rubber products such as waste tires, waste rubber hoses, and waste rubber sheets.

[0003] Currently, when dealing with waste rubber, usually a shredder is first used to perform rough crushing on the waste rubber, and then the roughly crushed waste rubber is transferred to a pulverizer, and the pulverizer is used to crush the waste rubber into particles. The processes are relatively scattered. And if a conveyor or other conveying equipment is used to automatically convey the roughly crushed waste rubber into the pulverizer, it will increase the equipment purchase and maintenance costs.

[0004] For example, a Chinese patent with the patent publication number CN118832765B discloses a recycling and processing integrated machine for waste rubber seals, including a screening cylinder and a crusher. A driving mechanism is jointly arranged behind the screening cylinder and the crusher. The screening cylinder is located below the crusher. A plurality of crushing rollers are rotatably connected inside the crusher. A rotating shaft is fixedly penetrated inside the crushing roller. The front and rear ends of the rotating shaft respectively penetrate to the front and rear of the crusher. Through-type inlets are symmetrically opened above the outer surface of the screening cylinder.

[0005] The above technical solution can only cut and crush rubber waste, similar to the rough crushing treatment using a shredder in the prior art. Subsequently, the roughly crushed rubber waste still needs to be transferred to a pulverizer for further crushing into particles, increasing the complexity of the process and reducing the processing efficiency of rubber waste.

Detailed Embodiment

[0028] The present invention will be further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as "set", "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Embodiment 1: A solid waste processing device for recycled rubber, as Figures 1 - 4 shown, includes a base 10, a crushing frame 11, a crushing box 12, crushing rollers 13, crushing gears 14, a pulverizing frame 15, a baffle plate 16, pulverizing knives 17, a pulverizing disc 18, and pulverizing heads 19. Two crushing frames 11 are symmetrically and fixedly connected to the front and rear of the base 10. A crushing box 12 is fixedly connected to the two crushing frames 11. It can be seen from Figure 3 that two crushing rollers 13 are rotatably connected to the front and rear of the crushing box 12 symmetrically. A number of protruding structures are arranged in an annular array on the crushing rollers 13. When the two crushing rollers 13 rotate relatively, the rubber is sheared and torn by the protruding structures. A crushing gear 14 is fixedly connected to the rotating shaft of each of the two crushing rollers 13. The crushing gears 14 on the two crushing rollers 13 are meshed with each other. Combining Figure 1 and Figure 2 it can be seen that two pulverizing frames 15 are symmetrically and fixedly connected to the left and right of the base 10. Baffle plates 16 are fixedly connected to the opposite ends of the two pulverizing frames 15. The baffle plates 16 are located below the crushing box 12. Combining Figure 3 and Figure 4 it can be seen that a plurality of pulverizing knives 17 are fixedly connected to the two baffle plates 16 together. The plurality of pulverizing knives 17 are distributed in an annular array, and cutting edges are provided at both ends of the pulverizing knives 17 perpendicular to the baffle plates 16. A pulverizing cavity is formed between the baffle plates 16 and the pulverizing knives 17. The crushing box 12 communicates with the upper side of the pulverizing cavity, so that the crushed rubber can flow into the pulverizing cavity. A pulverizing disc 18 is rotatably connected to the two baffle plates 16 together. The pulverizing disc 18 is located in the pulverizing cavity. A plurality of pulverizing heads 19 are fixedly connected to the pulverizing disc 18 in an annular array. The pulverizing heads 19 are used to squeeze the rubber onto the cutting edges of the pulverizing knives 17 to cut and pulverize the rubber.

[0030] As Figures 2 - 4As shown in the figure, it further includes a screening mechanism for enhancing the crushing effect. The screening mechanism is located outside the baffle plate 16. The screening mechanism includes a screening frame 20, a pushing plate 21, and a commutation component. The screening frame 20 is rotatably connected to the outside of the baffle plate 16. The screening frame 20 and the crushing disc 18 are coaxial. The screening frame 20 is annular, and through holes for screening rubber are arranged in an annular array on the side wall of the screening frame 20. A plurality of pushing plates 21 are installed on the inner wall of the screening frame 20 in an annular array. Both ends and both sides of the pushing plate 21 are in close contact with the baffle plate 16. The pushing plate 21 is used to drive the rubber remaining in the screening frame 20 to the upper side of the crushing disc 18, and can cooperate with the crushing knife 17 to cut the rubber during the rotation process. A commutation component is connected to the crushing disc 18. During the forward rotation of the crushing disc 18, the screening frame 20 can be driven to rotate in reverse through the commutation component.

[0031] As Figures 1 - 3 shown, the commutation component includes a blanking box 22, a main gear 23, a sub-gear 24, and a toothed ring 25. The blanking box 22 is fixedly connected to the base 10. The blanking box 22 is located below the screening frame 20. The materials with qualified particle size in the screening frame 20 will fall into the blanking box 22 under the action of gravity and fall out downward through the blanking box 22. The main gear 23 is fixedly connected to the rotating shaft of the crushing disc 18. The sub-gear 24 is rotatably connected to the outside of one of the baffle plates 16. The upper side of the sub-gear 24 is meshed with the main gear 23. The toothed ring 25 is installed on the screening frame 20, and the lower side of the toothed ring 25 is meshed with the sub-gear 24.

[0032] For the convenience of description, the rubber waste is simply referred to as rubber. When processing rubber, the rubber is put into the crushing box 12. The two crushing rollers 13 rotate relatively to perform rough crushing on the rubber. The crushed rubber flows downward through the crushing box 12 onto the rotating crushing disc 18 and will flow between two adjacent crushing heads 19 to Figure 4From this perspective, the crushing disc 18 rotates clockwise. During the rotation of the crushing disc 18, the rubber will continuously move towards the direction of the crushing knife 17 under the action of centrifugal force. Thus, the rubber will contact one end of the crushing head 19 close to the crushing knife 17. The rotating crushing head 19 will drag the rubber and squeeze it between the two crushing knives 17, so that the rubber will be further crushed by the blades of the crushing knife 17. During the process of the crushing head 19 dragging and squeezing the rubber, the rubber may be cut into strips by the crushing knife 17, resulting in an unsatisfactory crushing effect. Therefore, it is necessary to cut the rubber. When the crushing disc 18 rotates clockwise, it will drive the screening frame 20 to rotate counterclockwise through the main gear 23, the auxiliary gear 24 and the toothed ring 25. The pushing plate 21 can drag the rubber leaking from between the two crushing knives 17 in the opposite direction. And since blades are provided at both ends of the crushing knife 17, the rubber can be cut when dragged in the opposite direction. Thus, through the crushing head 19, the crushing knife 17 and the pushing plate 21, the rubber is further crushed, and the rubber can be crushed into granular form. The crushed rubber will fall into the screening frame 20. The rubber with qualified particle size will pass through the screening frame 20 and be discharged through the blanking box 22. The rubber with unqualified particle size will be driven upward by the pushing plate 21. When the rubber moves to the position on the upper side of the crushing disc 18 where there is no crushing knife 17, it will fall downward under the action of gravity, and thus fall onto the crushing disc 18 for re-crushing to ensure the crushing effect.

[0033] Embodiment 2: On the basis of Embodiment 1, as Figure 1 and Figure 2 shown, it further includes a material shaking mechanism for driving the screening frame 20 to shake. The material shaking mechanism is connected to the screening frame 20. The material shaking mechanism includes a shaking seat 30, a shaking rod 31, a first spring 32, a shaking disc 33 and a shaking block 34. Shaking seats 30 are slidably connected to opposite sides of the two crushing frames 11 in the horizontal direction. The screening frame 20 is slidably connected to the two shaking seats 30. The shaking seats 30 can provide a guiding function for the rotation of the screening frame 20. Two first springs 32 are sleeved on the guiding rods of the shaking seats 30. The first springs 32 are used to ensure that the shaking seats 30 are in the centered position. A shaking rod 31 is fixedly connected to the two shaking seats 30 together. A shaking disc 33 is fixedly connected to the rotating shaft of the auxiliary gear 24. When the auxiliary gear 24 rotates, it will drive the shaking disc 33 to rotate synchronously. Four shaking blocks 34 are fixedly connected in an annular array on the end face of the shaking disc 33 far from the auxiliary gear 24. A shaking block 34 is fixedly connected to one end of the shaking rod 31 close to the shaking disc 33. When the shaking disc 33 rotates, it drives the shaking rod 31 and the shaking seats 30 to shake through the extrusion between the shaking blocks 34.

[0034] As Figure 3 and Figure 4As shown in the figure, it further includes a drag reduction guide shaft 35 for guiding the toothed ring 25. A plurality of drag reduction guide shafts 35 are fixedly connected in an annular array on the side wall of the screening box 20. The toothed ring 25 is slidably connected to the plurality of drag reduction guide shafts 35. The pushing plate 21 is slidably connected to the screening box 20, and the sliding directions of the toothed ring 25 and the pushing plate 21 are both parallel to the axial direction of the screening box 20.

[0035] During the rotation of the secondary gear 24, the vibrating tray 33 will be driven to move synchronously. The vibrating tray 33 will push the vibrating rod 31 in a direction away from the baffle 16 through the extrusion cooperation between the vibrating blocks 34. The vibrating rod 31 drives the vibrating seat 30 to move synchronously and compresses the first spring 32. When the vibrating seat 30 moves, it will drive the screening box 20 to move synchronously. When the vibrating blocks 34 on the vibrating tray 33 and the vibrating rod 31 are disengaged, the first spring 32 will push the vibrating seat 30 to reset, thereby driving the screening box 20 to reciprocate during the crushing process and improving the screening efficiency; Since the toothed ring 25 is slidably connected to the screening box 20 through the drag reduction guide shaft 35, and the frictional force between the toothed ring 25 and the secondary gear 24 is relatively large, the toothed ring 25 will not reciprocate with the screening box 20, so as to reduce the wear between the toothed ring 25 and the secondary gear 24 and extend the service life; Since the pushing plate 21 is slidably connected to the screening box 20 and the two ends and both sides of the pushing plate 21 are in contact with the baffle 16, the pushing plate 21 will not reciprocate with the screening box 20 either, so as to normally drive the rubber to the upper side of the crushing disc 18.

[0036] Embodiment 3: On the basis of Embodiment 2, as Figure 2 and Figure 3 shown in the figure, it further includes a pressing mechanism for pressing the rubber onto the crushing roller 13. The pressing mechanism is installed on the crushing box 12. The pressing mechanism includes a sliding rod 40, a pressing rod 41, a second spring 42, a shaft seat 43, a shielding plate 44, a small gear 45 and a small rack 46. Four sliding rods 40 are symmetrically fixedly connected to the crushing box 12. A pressing rod 41 is slidably connected to the two sliding rods 40 on the same side. The second spring 42 is sleeved on the sliding rod 40. When the pressing rod 41 slides downward along the sliding rod 40, the second spring 42 will be compressed. Two shaft seats 43 are symmetrically fixedly connected to each pressing rod 41. The shaft seats 43 pass through and are slidably connected to the upper side wall of the crushing box 12. A shielding plate 44 is rotatably connected to the two shaft seats 43 on the same pressing rod 41. A small gear 45 is fixedly connected to the rotating shaft of the shielding plate 44. A small rack 46 is fixedly connected to the inner side wall of the upper side of the crushing box 12. The small rack 46 and the small gear 45 cooperate to drive the shielding plate 44 to rotate when the pressing rod 41 slides downward, so as to press the rubber onto the crushing roller 13 through the shielding plate 44.

[0037] As Figure 2 and Figure 5As shown in the figure, it further includes a transmission mechanism for driving the sliding of the pressing rod 41. The transmission mechanism is connected to the crushing roller 13. The transmission mechanism includes a transmission frame 50, a driven frame 51, a third spring 52, a reciprocating lead screw 53, a driving frame 54 and a pressing plate 55. The transmission frame 50 is fixedly connected to the crushing box 12. The driven frame 51 is slidably connected to the transmission frame 50 in the vertical direction. The third spring 52 is sleeved on the guide rod of the driven frame 51. The pressing plate 55 is fixedly connected to the driven frame 51. When the driven frame 51 slides downward, the third spring 52 will be compressed, and the pressing rod 41 will be pushed downward through the pressing plate 55. The middle part of the reciprocating lead screw 53 is rotatably connected to the transmission frame 50. One end of the reciprocating lead screw 53 is fixedly connected to the adjacent crushing roller 13, and the other end is rotatably connected to the crushing frame 15. The driving frame 54 is threadedly connected to the reciprocating lead screw 53. When the driving frame 54 slides toward the crushing box 12, the driven frame 51 will be pressed downward. The guide rail for guiding the driving frame 54 is fixedly connected to the crushing box 12.

[0038] During the rotation of the crushing roller 13, the reciprocating lead screw 53 will be driven to rotate synchronously. The reciprocating lead screw 53 will drive the driving frame 54 to move reciprocally. When the driving frame 54 moves toward the crushing box 12, it will squeeze the driven frame 51 downward. The third spring 52 will be compressed. When the driven frame 51 moves downward, it will push the pressing rod 41 downward through the pressing plate 55, so that the pressing rod 41 drives the shaft seat 43 and the shielding plate 44 to slide downward, and the second spring 42 will also be compressed. During the downward sliding of the shaft seat 43, the small rack 46 will drive the shielding plate 44 to rotate through the small gear 45. The shielding plate 44 can press the rubber on the crushing roller 13 downward, increasing the friction between the rubber and the crushing roller 13, preventing the rubber from getting stuck on the upper side of the crushing roller 13, enabling the rubber to be quickly crushed by the crushing roller 13, and effectively preventing the rubber in the crushing box 12 from popping out; when the driving frame 54 moves away from the crushing box 12, the third spring 52 will gradually push the driven frame 51 to reset upward, and the second spring 42 will push the shaft seat 43 to slide upward and reset. The shielding plate 44 reversely resets under the action of the small gear 45 and the small rack 46.

[0039] Embodiment 4: On the basis of Embodiment 3, as Figure 1 、 Figure 2 and Figure 5As shown, it also includes a material control mechanism for automatically feeding rubber, the material control mechanism is connected to the driven frame 51, the material control mechanism includes a material control box 60, a shear plate 61, a material control gear 62 and a material control rack 63, the material control box 60 is fixedly connected to the upper side of the crushing frame 11, and two shear plates 61 are symmetrically rotatably connected in the material control box 60, the shear plates 61 are in the shape of a cross, and a blade is provided at the outer end of the shear plate 61, and a material control gear 62 is rotatably connected to the rotating shaft of the shear plate 61 through a one-way bearing, and two material control racks 63 are symmetrically fixed to the driven frame 51, the material control rack 63 and the material control gear 62 cooperate to drive the two shear plates 61 to rotate relative to each other, and the material control rack 63 can drive the shear plate 61 to rotate only when it moves downward.

[0040] The rubber to be processed is stored in the material control box 60 in advance. When the driven frame 51 moves downward, the two shear plates 61 will be driven to rotate relative to each other through the material control rack 63 and the material control gear 62 before the pressure plate 55 and the pressure rod 41 come into contact. The shear plates 61 will push the rubber in the material control box 60 downward, causing the rubber to fall downward onto the crushing roller 13. Moreover, since a blade is provided at the outer end of the shear plate 61, when a longer rubber is stuck at the outer end of the two shear plates 61, the two shear plates 61 can shear the rubber. The sheared rubber can more easily enter between the two crushing rollers 13 for crushing. Moreover, the amount of rubber added can be more accurately controlled by rotating the shear plate 61 to feed the material. Since the material control gear 62 is installed on the rotating shaft of the shear plate 61 through a one-way bearing, the material control rack 63 will not drive the shear plate 61 to rotate through the material control gear 62 when the driven frame 51 moves upward.

[0041] like Figure 3 and Figure 6 As shown, it also includes a drive base 70, a motor 71 and a pulley group 72 for driving the reciprocating screw 53 and the pulverizing disk 18 to rotate. The drive base 70 is fixedly connected to the material baffle plate 16 without the main gear 23 installed. The drive base 70 is fixedly connected to the motor 71. The motor 71 and the rotating shaft of the pulverizing disk 18 are fixedly connected, and the rotating shaft of the pulverizing disk 18 and one of the reciprocating screws 53 are connected through the pulley group 72. The pulley group 72 consists of two single-groove pulleys and a transmission belt.

[0042] After the motor 71 is started, it drives the crushing disc 18 to rotate, and drives the two crushing rollers 13 and the reciprocating screw 53 to rotate through the pulley set 72.

[0043] The above has introduced the present application in detail. Specific examples are used herein to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
