Figure 3 It can be seen that there are two crushing rollers 13 connected to the crushing box 12 for symmetrical rotation. The crushing rollers 13 are provided with a plurality of protrusions in an annular array. When the two crushing rollers 13 rotate relative to each other, the rubber is sheared and shredded by the protrusions. A crushing gear 14 is fixed to the rotating shafts of the two crushing rollers 13. The crushing gears 14 on the two crushing rollers 13 are meshed with each other. Figure 1 and Figure 2 It can be seen that two crushing frames 15 are fixedly connected to the base 10 symmetrically, and a baffle plate 16 is fixedly connected to the opposite ends of the two crushing frames 15. The baffle plate 16 is located at the lower side of the crushing box 12. Figure 3 and Figure 4 It can be seen that a plurality of crushing knives 17 are fixedly connected to the two baffle plates 16, and the plurality of crushing knives 17 are distributed in a circular array. The crushing knives 17 are provided with blades at both ends perpendicular to the baffle plates 16. A crushing chamber is formed between the baffle plates 16 and the crushing knives 17. The crushing box 12 is connected to the upper side of the crushing chamber so that the crushed rubber can flow into the crushing chamber. A crushing disk 18 is rotatably connected to the two baffle plates 16, and the crushing disk 18 is located in the crushing chamber. A plurality of crushing heads 19 are fixedly connected to the crushing disk 18 in a circular array. The crushing head 19 is used to squeeze the rubber onto the blade of the crushing knife 17 to cut and crush the rubber.

[0027] like Figure 2-Figure 4As shown, it also includes a screening mechanism for improving the crushing effect. The screening mechanism is located on the outside of the baffle plate 16. The screening mechanism includes a screening frame 20, a pushing plate 21 and a reversing assembly. The screening frame 20 is rotatably connected to the outside of the baffle plate 16. The screening frame 20 and the crushing disk 18 are coaxial. The screening frame 20 is annular, and the side wall of the screening frame 20 is provided with through holes for screening rubber in a ring array. A plurality of pushing plates 21 are installed on the inner wall of the screening frame 20 in a ring array. The two ends of the pushing plate 21 are in close contact with the baffle plates 16 on both sides. The pushing plate 21 is used to drive the rubber remaining in the screening frame 20 to the upper side of the crushing disk 18, and can cooperate with the crushing knife 17 to cut the rubber during the rotation process. The crushing disk 18 is connected with a reversing assembly, and the reversing assembly can drive the screening frame 20 to reverse during the forward rotation of the crushing disk 18.

[0028] like Figure 1-Figure 3 As shown, the reversing assembly includes a feed box 22, a main gear 23, a sub gear 24 and a gear ring 25. The feed box 22 is fixedly connected to the base 10, and the feed box 22 is located at the lower side of the screening frame 20. The materials with qualified particle sizes in the screening frame 20 will fall into the feed box 22 under the action of gravity, and fall downward through the feed box 22. The main gear 23 is fixedly connected to the rotating shaft of the crushing disk 18, and the sub gear 24 is rotatably connected to the outer side of one of the baffle plates 16. The upper side of the sub gear 24 is meshed with the main gear 23, and a gear ring 25 is installed on the screening frame 20, and the gear ring 25 is meshed with the lower side of the sub gear 24.

[0029] For the convenience of description, the rubber waste is referred to as rubber. When processing the rubber, the rubber is put into the crushing box 12. The two crushing rollers 13 rotate relative to each other to roughly crush the rubber. The crushed rubber flows downward through the crushing box 12 to the crushing disk 18 in the rotating process, and flows between the two adjacent crushing heads 19 to Figure 4From the perspective of FIG, the crushing disk 18 rotates clockwise. During the rotation of the crushing disk 18, the rubber will continuously move toward the crushing knife 17 under the action of centrifugal force, so that the rubber will contact the end of the crushing head 19 close to the crushing knife 17. During the rotation, the 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 knives 17. In the process of the crushing head 19 dragging and squeezing the rubber, the rubber may be cut into long strips by the crushing knife 17, resulting in an unsatisfactory crushing effect, so the rubber needs to be cut. When the crushing disk 18 rotates clockwise, it will drive the screening frame 20 to rotate counterclockwise through the main gear 23, the sub-gear 24 and the gear ring 25, and the push plate 21 The rubber leaking out from between the two crushing knives 17 can be dragged in the opposite direction, and because both ends of the crushing knife 17 are provided with blades, the rubber can be cut when dragged in the opposite direction, so that the rubber can be further crushed by the crushing head 19, the crushing knife 17 and the push plate 21, so that the rubber can be crushed into particles, and 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 discharge box 22, and the rubber with unqualified particle size will be driven upward by the push plate 21, and when the rubber moves to the position where there is no crushing knife 17 on the upper side of the crushing disk 18, it will fall downward under the action of gravity, and then fall onto the crushing disk 18 to be crushed again, thereby ensuring the crushing effect.

[0030] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 2 As shown, it also includes a shaking mechanism for driving the screening frame 20 to shake, the shaking mechanism is connected to the screening frame 20, the shaking mechanism includes a shaking seat 30, a shaking rod 31, a No. 1 spring 32, a shaking plate 33 and a shaking block 34, the two crushing frames 11 are both connected to the shaking seat 30 in a sliding manner in the horizontal direction on the opposite sides, the screening frame 20 and the two shaking seats 30 are slidably connected, the shaking seat 30 can provide a guide for the rotation of the screening frame 20, and two No. 1 springs 32 are sleeved on the guide rod of the shaking seat 30. 32 is used to ensure that the material shaking seat 30 is located in the center position, and a material shaking rod 31 is fixedly connected to the two material shaking seats 30. A material shaking plate 33 is fixedly connected to the rotating shaft of the sub-gear 24. When the sub-gear 24 rotates, it will drive the material shaking plate 33 to rotate synchronously. Four material shaking blocks 34 are fixedly connected in a circular array on the end surface of the material shaking plate 33 away from the sub-gear 24. A material shaking block 34 is fixedly connected to one end of the material shaking rod 31 close to the material shaking plate 33. When the material shaking plate 33 rotates, the shaking rod 31 and the material shaking seat 30 are driven to shake through the extrusion between the shaking blocks 34.

[0031] like Figure 3 and Figure 4As shown, it also includes a drag reduction guide shaft 35 for guiding the gear ring 25. A plurality of drag reduction guide shafts 35 are fixedly connected in a ring array on the side wall of the screening frame 20. The gear ring 25 is slidably connected to the plurality of drag reduction guide shafts 35. The push plate 21 is slidably connected to the screening frame 20, and the sliding directions of the gear ring 25 and the push plate 21 are parallel to the axial direction of the screening frame 20.

[0032] The rotation of the secondary gear 24 will drive the shaking plate 33 to move synchronously, and the shaking plate 33 will push the shaking rod 31 in the direction away from the baffle plate 16 through the extrusion cooperation between the shaking blocks 34. The shaking rod 31 drives the shaking seat 30 to move synchronously and compresses the No. 1 spring 32. When the shaking seat 30 moves, it will drive the screening frame 20 to move synchronously. When the shaking plate 33 and the shaking block 34 on the shaking rod 31 are out of contact, the No. 1 spring 32 will push the shaking seat 30 to reset, thereby driving the screening frame 20 to shake back and forth during the crushing process, improving Screening efficiency; since the gear ring 25 is slidably connected to the screening frame 20 through the drag-reducing guide shaft 35, and the friction between the gear ring 25 and the sub-gear 24 is relatively large, the gear ring 25 will not follow the screening frame 20 to reciprocate and shake, so as to reduce the wear between the gear ring 25 and the sub-gear 24 and extend the service life; since the push plate 21 and the screening frame 20 are slidably connected, and the two ends of the push plate 21 are in contact with the baffle plates 16 on both sides, the push plate 21 will not follow the screening frame 20 to reciprocate and shake, so as to normally drive the rubber to the upper side of the crushing disk 18.

[0033] Embodiment 3: Based on embodiment 2, Figure 2 and Figure 3 As shown, it also includes a pressing mechanism for pressing the rubber onto the crushing roller 13, which is installed on the crushing box 12. The pressing mechanism includes a slide bar 40, a pressing bar 41, a second spring 42, an axle seat 43, a baffle plate 44, a small gear 45 and a small rack 46. Four slide bars 40 are symmetrically fixed to the crushing box 12. A pressing bar 41 is slidably connected to the two slide bars 40 on the same side. The slide bar 40 is sleeved with a second spring 42. When the pressing bar 41 slides downward along the slide bar 40, it presses the second spring 42 The two shaft seats 43 on the same pressure rod 41 are connected to a shielding plate 44 which rotates together. A pinion 45 is fixed to the rotating shaft of the shielding plate 44. A small rack 46 is fixed to the inner wall of the upper side of the crushing box 12. The small rack 46 and the small gear 45 cooperate with each other to drive the shielding plate 44 to rotate when the pressure rod 41 slides downward, so as to press the rubber onto the crushing roller 13 through the shielding plate 44.

[0034] like Figure 2 and Figure 5As shown, it also includes a transmission mechanism for driving the pressure rod 41 to slide, 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 screw 53, an active frame 54 and a pressure plate 55, the crushing box 12 is fixedly connected with the transmission frame 50, the driven frame 51 is slidably connected to the transmission frame 50 in the vertical direction, the guide rod of the driven frame 51 is sleeved with a third spring 52, the driven frame 51 is fixedly connected with the pressure plate 55, and the driven frame 51 moves downward. When sliding, the No. 3 spring 52 will be compressed, and the pressure rod 41 will be pushed downward through the pressure plate 55. The middle part of the reciprocating screw 53 is rotatably connected to the transmission frame 50. One end of the reciprocating screw 53 is fixedly connected to the adjacent crushing roller 13, and the other end is rotatably connected to the crushing frame 15. The active frame 54 is threadedly connected to the reciprocating screw 53. When the active frame 54 slides toward the direction close to the crushing box 12, the driven frame 51 will be pressed downward. The crushing box 12 is fixedly connected with a guide rail for guiding the active frame 54.

[0035] The reciprocating screw 53 will be driven to rotate synchronously during the rotation of the crushing roller 13, and the reciprocating screw 53 will drive the active frame 54 to move back and forth. When the active frame 54 moves toward the direction of the crushing box 12, it will press the driven frame 51 downward, and the No. 3 spring 52 will be compressed. When the driven frame 51 moves downward, it will push the pressure rod 41 downward through the pressure plate 55, so that the pressure rod 41 drives the shaft seat 43 and the baffle plate 44 to slide downward, and the No. 2 spring 42 will also be compressed. When the shaft seat 43 slides downward, the small rack 46 will drive the baffle plate 44 to rotate through the small gear 45, and the baffle plate 44 will be blocked. The plate 44 can press the rubber on the crushing roller 13 downward, increase the friction between the rubber and the crushing roller 13, prevent the rubber from being stuck on the upper side of the crushing roller 13, enable the rubber to be quickly crushed by the crushing roller 13, and effectively prevent the rubber in the crushing box 12 from popping out; when the active frame 54 moves away from the crushing box 12, the No. 3 spring 52 will gradually push the driven frame 51 to reset upward, the No. 2 spring 42 will push the shaft seat 43 to slide upward and reset, and the baffle plate 44 will reverse and reset under the action of the pinion 45 and the small rack 46.

[0036] Embodiment 4: Based on the embodiment 3, 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.

[0037] 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.

[0038] 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.

[0039] 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.
