Technical Field

[0001] This utility model relates to the field of rubber production equipment technology, and in particular to a machine-side crusher for rubber production that is easy to collect waste materials. Background Technology

[0002] The production of rubber products generates a large amount of scrap and waste. Recycling these wastes is of great significance for reducing production costs and achieving green manufacturing. With the rapid development of the rubber industry, the world generates more than 10 million tons of rubber waste annually, of which about 30% comes from scraps generated during the production process.

[0003] Chinese Patent CN213412619U discloses a machine-side crusher for rubber production, comprising a support plate and a crushing box. The crushing box is installed through the top of the support plate, and a first motor is fixed to the top of the support plate. The first motor drives a first gear to rotate via a first rotating shaft. The first gear meshes with a second gear and drives a second rotating shaft to rotate. The second rotating shaft is connected to both sides of the crushing box via bearings. However, this prior art has the following technical defects: its crushing mechanism lacks an effective screening device, resulting in the inability to automatically classify and collect the crushed rubber particles. This not only reduces the waste recycling efficiency but also increases the workload of subsequent manual sorting. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a machine-side crusher for rubber production that facilitates the collection of waste materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A machine-side shredder for easy waste collection in rubber production includes a base, a feeding frame embedded in the top of the base, a shredding frame mounted on the top of the base above the feeding frame, two meshing shredding rollers rotatably connected inside the shredding frame, a motor housing for driving the two shredding rollers to rotate fixedly connected to one side of the shredding frame, a feeding frame fixedly connected to the top of the shredding frame, and a feeding mechanism connected to the feeding frame on one side of the base. The bottom of the base is supported by two first support frames, and an inclined vibrating frame is provided between the two first support frames. The high end of the vibrating frame is connected to the two first support frames through a vibrating mechanism. A vibrating motor is fixedly connected below the high end of the vibrating frame. Both sides of the low end of the vibrating frame are rotatably connected to the two first support frames through rotating shafts, so that the vibrating frame constitutes an inclined vibrating screen bed with the rotating shaft as the swing fulcrum, driven by the vibrating motor and elastically suspended by the vibrating mechanism. A screening screen is installed at the bottom inner part of the vibrating frame, and a first collection frame is provided below the screening screen in the vibrating frame.

[0006] As a further improvement of this utility model, the feeding mechanism includes a belt conveyor fixedly connected to one side of the feeding frame, the other end of the belt conveyor being supported by a second support frame, and a servo motor for driving the belt conveyor is installed on one side of the belt conveyor.

[0007] As a further improvement of this utility model, the vibration mechanism includes a fixed plate disposed between two first support frames, and vibration springs are fixedly connected to both sides of the top of the fixed plate, and the other ends of the two vibration springs are fixedly connected to the bottom of the vibration frame.

[0008] As a further improvement of this utility model, a second collection frame for collecting the material on the screen is placed below the lower end of the vibrating frame.

[0009] As a further improvement of this utility model, a limiting groove is provided on the side of each of the two first support frames that are close to each other, and a limiting strip is fixedly connected to both sides of the first collection frame, and the two limiting strips slide in the two limiting grooves respectively.

[0010] As a further improvement of this utility model, a damping shaft is rotatably connected to one side of each of the two first support frames, and a rotating block is fixedly sleeved on each of the two damping shafts. After the two rotating blocks rotate, they can prevent the two limiting strips from disengaging from the two limiting grooves.

[0011] As a further improvement of this utility model, a through groove is provided at the bottom of the vibrating frame, and mounting grooves are provided on both sides of the through groove on the vibrating frame. The two ends of the screening screen are respectively engaged in the two mounting grooves and fixed by multiple fixing bolts.

[0012] The beneficial effects of this utility model are: The crushed rubber particles are graded by a screening screen set at the bottom of the vibrating frame, and qualified fine materials are collected by a first collection frame located below the screening screen. At the same time, a second collection frame is set at the bottom of the vibrating frame to receive large particles that do not pass through the screening screen, thereby realizing automatic screening and classification collection of crushed materials.

[0013] By creating a limiting groove on the first support frame that slides into the limiting strip on the first collection frame, and by using a rotating block that can rotate around the damping axis to support the limiting strip in the horizontal position, the first collection frame is effectively prevented from accidentally leaving the collection area due to vibration during equipment operation.

[0014] By inserting both ends of the screening mesh into the mounting grooves on the vibrating frame and securing them with fixing bolts, the installation of the screening mesh is stable and reliable. At the same time, this connection method also makes it easy to loosen the fixing bolts to quickly replace the screening mesh when needed, thus adapting to different particle grading requirements.

[0015] This invention achieves material grading through a screening screen, and uses the cooperation of the mounting groove and fixing bolts to make the screening screen stable and easy to replace. At the same time, the cooperation of the limiting groove, the limiting strip and the rotating block ensures that the first collection frame is stably positioned in a vibration environment.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-5A machine-side crusher for easy waste collection in rubber production includes a base 1. A feeding frame 12 is embedded in the top of the base 1. A crushing frame 3 is installed on the top of the base 1 above the feeding frame 12. The feeding frame 12 is used to receive the crushed material falling from the crushing frame 3 and guide it to the subsequent processing unit. Two meshing crushing rollers 21 are rotatably connected inside the crushing frame 3. The two crushing rollers 21 achieve shearing and crushing of rubber waste through toothed meshing. A motor housing 22 for driving the two crushing rollers 21 is fixedly connected to one side of the crushing frame 3. The motor housing 22 mainly consists of a drive motor and two transmission gears, which can synchronously transmit power to the two crushing rollers 21. To ensure their opposite rotation, a feed frame 4 is fixedly connected to the top of the crushing frame 3. The feed frame 4 serves as a channel for materials to enter the crushing area. A feeding mechanism connected to the feed frame 4 is provided on one side of the base 1. The feeding mechanism includes a belt conveyor 5 fixedly connected to one side of the feed frame 4. The belt conveyor 5 smoothly lifts the rubber waste to be crushed to the inlet of the feed frame 4 through a continuous conveyor belt. The other end of the belt conveyor 5 is supported by a second support frame 7. The second support frame 7 provides stable height support for the far end of the belt conveyor 5. A servo motor 6 is installed on one side of the belt conveyor 5 to drive its operation. The servo motor 6 drives the active roller of the conveyor belt to rotate through a reduction mechanism.

[0021] The base 1 is supported by two first support frames 2, which together bear the weight of the main body of the equipment. An inclined vibrating frame 8 is located between the two first support frames 2. The vibrating frame 8 is used for screening and conveying the crushed material. The upper end of the vibrating frame 8 is connected to the two first support frames 2 via a vibrating mechanism. The vibrating mechanism includes a fixed plate 9 located between the two first support frames 2, which serves as the mounting base for the vibrating mechanism. Vibrating springs 10 are fixedly connected to both sides of the top of the fixed plate 9. The other ends of the two vibrating springs 10 are fixedly connected to the bottom of the vibrating frame 8. 10 provides elastic support for the vibrating frame 8 and allows it to generate reciprocating vibration. A vibrating motor 16 is fixedly connected below the high end of the vibrating frame 8. The unbalanced centrifugal force generated when the vibrating motor 16 rotates serves as the excitation source to drive the vibrating frame 8 to vibrate. Both sides of the low end of the vibrating frame 8 are rotatably connected to the two first support frames 2 through the rotating shaft 13. The rotating shaft 13 constitutes the hinge fulcrum for the swing of the vibrating frame 8, so that the vibrating frame 8 constitutes an inclined vibrating screen bed with the rotating shaft 13 as the swing fulcrum, driven by the vibrating motor 16 and elastically suspended by the vibration mechanism, so that the vibrating frame 8 generates directional vibration to promote the material to move along the screen surface to the low end and be screened.

[0022] A screening screen 11 is installed at the bottom inner side of the vibrating frame 8. The screening screen 11 classifies the crushed rubber particles according to the mesh size. Material of the qualified particle size passes through the screen mesh, while oversized particles are intercepted. A through groove is provided at the bottom inner side of the vibrating frame 8. The through groove provides an installation position for the screening screen 11 and allows fine materials to pass through. Mounting grooves 23 are opened on both sides of the through groove on the vibrating frame 8. The mounting grooves 23 are used to position and support the screening screen 11. The two ends of the screening screen 11 are respectively engaged in the two mounting grooves 23 and are respectively fixed by multiple bolts 24. The screen 11 is fixed to the vibrating frame 8 by fixing bolts 24 to prevent it from shifting due to vibration. The screen 11 can be replaced by removing the fixing bolts 24 to adapt to different rubber particle grading. The vibrating frame 8 is provided with a first collection frame 14 below the screen 11. The first collection frame 14 is used to collect qualified fine material that has passed through the screen 11. A second collection frame 15 is placed below the lower end of the vibrating frame 8 to collect the material on the screen. The second collection frame 15 receives large particles that have not passed through the screen 11.

[0023] Each of the two first support frames 2 has a limiting groove 17 on one side that is close to each other. The limiting groove 17 provides a vertical sliding track for the first collection frame 14. Both sides of the first collection frame 14 are fixedly connected to limiting strips 18. The two limiting strips 18 slide in the two limiting grooves 17 respectively. The cooperation between the limiting strips 18 and the limiting grooves 17 restricts the first collection frame 14 to move only in the vertical direction, ensuring that it is accurately located below the screening screen 11. One side of each of the two first support frames 2 is rotatably connected to a damping shaft 19. The damping shaft 19 provides a certain rotational resistance. Two rotating blocks 20 are fixedly sleeved on each of the two damping shafts 19. When the rotating blocks 20 are rotated to the horizontal position, they can support the limiting strips 18 to prevent the first collection frame 14 from accidentally slipping due to vibration during equipment operation.

[0024] When using this utility model, firstly, the rubber waste to be processed is placed on the conveyor belt of the belt conveyor 5. Then, the servo motor 6 is started to drive the belt conveyor 5 to start running, conveying the rubber waste into the feeding frame 4. The material is guided into the crushing frame 3 through the feeding frame 4. Inside the crushing frame 3, the two crushing rollers 21 driven by the motor box 22 keep rotating in opposite directions, so that the rubber waste is crushed by the meshing teeth of the two crushing rollers 21.

[0025] The crushed material falls from the bottom of the crushing frame 3, is received by the feeding frame 12, and guided onto the vibrating frame 8. Then, the vibrating motor 16 is started. The excitation force generated by the vibrating motor 16 is transmitted through the vibrating spring 10, causing the vibrating frame 8 to vibrate directionally around the rotating shaft 13. The material falling on the high-end screening screen 11 of the vibrating frame 8 moves towards the low end under the action of vibration.

[0026] Material smaller than the mesh size of the screening screen 11 passes through the screening screen 11 and falls into the first collection frame 14. Material that does not pass through the screening screen 11 is conveyed to the lower end of the vibrating frame 8 and slides into the second collection frame 15.

[0027] When the screening screen 11 needs to be replaced, the fixing bolt 24 can be loosened and the screening screen 11 can be removed from the mounting slot 23 for replacement.

[0028] When picking up or placing the first collection frame 14, the rotating block 20 on the damping shaft 19 can be rotated to support or disengage from the limiting strip 18 so that the first collection frame 14 can slide along the limiting groove 17 for picking up or placing.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
