Description

Technical Field

[0001] This utility model relates to the field of rubber production technology, and in particular to a rubber raw material crushing device for rubber production. Background Technology

[0002] Rubber is an elastic material, usually composed of high molecular polymers, the most common of which are natural rubber and synthetic rubber. In the production process of rubber, the raw materials used for production are usually subjected to preliminary treatment. At this time, a crushing device is needed to break them down into small particles or powders so that they can be mixed, processed and manufactured in the future.

[0003] A search revealed Chinese Patent Publication No. N211105006U, which discloses a rubber raw material crushing device for rubber production. The device includes a crushing chamber with a discharge port at the bottom right side of the chamber's inner cavity. A conveying inclined plate is horizontally fixed to the bottom of the inner cavity, and a defective product discharge port is located at the bottom left side of the inner cavity, above the conveying inclined plate. This invention, through the coordinated use of a material collection frame, a hanging plate, a defective product discharge port, a support rail, a feeding hose, a filter frame, a moving block, a moving trough, an electric telescopic rod, a connecting plate, a filter inclined screen, and a discharge port, can screen the crushed rubber raw materials.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a rubber raw material crushing device for rubber production, comprising a housing 1, a material feeding mechanism 2 on the top wall of the housing 1, a material feeding groove 19 on one side of the top wall of the housing 1, a bracket 6 fixedly connected to the side wall of the housing 1, a servo motor 7 fixedly connected to the side wall of the bracket 6, the output end of the servo motor 7 passing through the bracket 6 and fixedly connected to an incomplete gear 8, a rack 5 meshing on the upper side of the incomplete gear 8, a through groove 11 passing through the side wall of the housing 1, the rack 5 passing through the through groove 11 and fixedly connected to a screening plate 12, one end of a spring 9 fixedly connected to the front and rear sides of the rack 5, the other ends of the two springs 9 being fixedly connected to the inner wall of the through groove 11, a fixing frame 14 fixedly connected to the lower middle part of one side of the inner wall of the housing 1, and two springs 9 on the rear wall of the fixing frame 14. Both sides are rotatably connected to crushing rollers 15. The front ends of both crushing rollers 15 penetrate the front wall of the box 1 and are fixedly connected to gears 4. The two gears 4 mesh with each other. The rear end of one crushing roller 15 penetrates the rear wall of the box 1 and is fixedly connected to a servo motor 18. Both sides of the rear wall of the material discharge trough 19 are rotatably connected to crushing rollers 20. The front ends of both crushing rollers 20 penetrate the front wall of the box 1 and are fixedly connected to gears 3. The two gears 3 mesh with each other. The rear end of one crushing roller 20 penetrates the rear wall of the box 1 and is fixedly connected to a servo motor 21. The rear wall of the through groove 21 is fixedly connected to a positioning rod 10. The front end of the positioning rod 10 penetrates the rack 5 and is fixedly connected to the front wall of the through groove 21. Two springs 9 are set on the outer periphery of the front and rear ends of the positioning rod 10.

[0031] Specifically, the rubber raw material to be crushed is fed into the housing 1 through the feed chute 19. The servo motor 21 and gear 3 work together to rotate the two crushing rollers 20, initially crushing the raw material. The crushed material falls onto the screening plate 12. Then, the servo motor 7 drives the incomplete gear 8 to rotate. When the incomplete gear 8 meshes with the rack 5, it moves the rack 5. As the rack 5 moves, it compresses the spring 9. Therefore, when the incomplete gear 8 disengages from the rack 5, the spring 9 pushes the rack 5 back and forth, allowing it to reciprocate within the through groove 11. The positioning rod 10 can limit the spring 9 to prevent it from bending under pressure. When the rack 5 moves, it can drive the connected screening plate 12 to move back and forth quickly and screen the raw materials on the screening plate 12. The raw materials that meet the standards will fall through the screening plate 12, while the raw materials that do not meet the standards will slide down the screening plate 12 into the fixed frame 14. The servo motor 18 and the gear 4 drive the two crushing rollers 15 to rotate, so that the unqualified raw materials can be crushed again by the crushing rollers 15. This eliminates the need for workers to take out the unqualified raw materials and put them back in for crushing, thus improving the processing efficiency.

[0032] Reference Figure 1 , Figure 3 and Figure 4 The material feeding mechanism 2 includes a feeding shell 201, which is fixedly connected to the top wall of the box 1 and communicates with the feeding chute 19. A feeding plate 202 is fixedly connected to the upper side of the middle part of the inner wall of the feeding shell 201. A feeding plate 204 is attached to the bottom wall of the feeding plate 202. A through groove 205 is opened on the side wall of the feeding shell 201. A moving block 207 is fixedly connected to one side of the feeding plate 204. One end of the moving block 207 passes through the through groove 205. An electric push rod 203 is fixedly connected to the lower part of one side of the feeding shell 201. The output end of the electric push rod 203 is fixedly connected to the rear wall of the moving block 207. The front and rear ends of the feeding plate 204 pass through the front and rear walls of the feeding shell 201, respectively. A limit rod 206 passes through the middle of the moving block 207. The front and rear ends of the limit rod 206 are fixedly connected to the front and rear walls of the through groove 205.

[0033] Specifically, by activating the electric push rod 203, the movable block 207 connected to the output end can be driven to move back and forth reciprocally. When the movable block 207 moves, it can drive the fixed discharge plate 204 to move back and forth reciprocally. Since the movable block 207 has a limit rod 206 passing through it, the limit rod 206 can limit the movable block 207, thereby ensuring the stability of the movement of the movable block 207 and the discharge plate 204. When the slots on the discharge plate 204 and the discharge plate 202 overlap, the raw material in the discharge shell 201 is discharged. The material will fall into the feeding trough 19 through the slots on the feeding plate 1 (202) and the feeding plate 2 (204), where it will be initially crushed by the crushing roller 2 (20). When the slots on the feeding plate 1 (202) and the feeding plate 2 (204) are staggered, the feeding plate 1 (202) and the feeding plate 2 (204) can seal each other, thus preventing the material from falling further. This achieves the effect of intermittent feeding, preventing the material from accumulating, ensuring the crushing effect, and allowing the operator to pour all the material into the feeding shell 201 without the need for manual intermittent feeding, making it more convenient to use.

[0034] Reference Figure 2 Limiting rods 13 are fixedly connected to both sides of the rear wall inside the box 1. The front ends of the two limiting rods 13 penetrate the screening plate 12 and are fixedly connected to the front wall inside the box 1.

[0035] Specifically, by setting a limiting rod 13 inside the screening plate 12 and fixing the limiting rod 13 inside the box 1, the screening plate 12 can be limited by the limiting rod 13, thus ensuring the stability of the screening plate 12 during screening.

[0036] Reference Figure 2 A screening plate 16 is fixedly connected to the bottom wall of the fixed frame 14, and the front end of the screening plate 16 penetrates the front wall of the box 1; a collection box 17 is slidably connected to the lower part of the box 1, and the front end of the collection box 17 penetrates the front wall of the box 1.

[0037] Specifically, the screening plate 16 can filter the raw materials after they have been crushed by the crushing roller 15, and collect the raw materials that do not meet the standards for further processing. The collection box 17 in the lower part of the box 1 can collect the filtered raw materials that meet the standards, so that the staff can take the raw materials out later.

[0038] Working principle: In actual use, starting the servo motor 7 drives the incomplete gear 8 to rotate and move the meshing rack 5. When the rack 5 moves, it compresses the spring 9, causing the rack 5 to reciprocate. This drives the connected screening plate 12 to reciprocate rapidly, screening the raw materials on the screening plate 12. Materials that do not meet the standards will fall into the fixed frame 14 along the screening plate 12 and be crushed again by the crushing roller 15. This eliminates the need for workers to remove the unqualified materials and refill them for crushing, improving processing efficiency. In addition, starting the electric push rod 203 drives the moving block 207 connected to the output end to reciprocate back and forth, which in turn drives the discharge plate 204 to reciprocate back and forth. When the grooves on the discharge plate 204 and the discharge plate 202 overlap, the raw materials will fall into the discharge trough 19 through the grooves and be crushed, thus achieving the effect of intermittent material discharge, preventing material accumulation and ensuring crushing effect.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
