Description

Technical Field

[0001] The utility model belongs to the technical field of rubber production and processing, and specifically relates to a rubber dry-mixing crusher. Background Art

[0002] Rubber products refer to the activities of producing various rubber products using natural and synthetic rubber as raw materials, and also include rubber products produced from waste rubber. Rubber products are difficult to degrade under natural conditions. Used rubber products will cause great pollution to the environment if they are not collected and processed in a centralized manner. Recycling and reusing rubber products is an economical and environmentally friendly practice. When recycling and reusing, crushing the rubber is the first step.

[0003] When rubber is recycled and crushed, it is often cut and crushed. However, the volume of rubber produced by cutting and crushing is generally large. The reason is that during the rotational cutting, it cannot be guaranteed that all rubber can be cut evenly. If large volumes or large pieces of rubber are not cut in time, there may be problems with incomplete crushing and cutting. Therefore, before the rubber is cut and crushed, it needs to be crushed and cut once. After the crushing and cutting is completed, it is cut and crushed again. This not only improves the crushing and cutting efficiency of the rubber, but also obtains more uniform rubber recycling products.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0025] A rubber dry mixing crusher, such as Figure 1 , Figure 2 As shown, it includes a crushing box 1, which is a hollow rectangular body. A feed hopper 12 is fixedly installed on the top of the crushing box 1. Two groups of left and right guide plates 13 are fixedly installed on the upper side of the cavity of the crushing box 1. The guide plates 13 are in a “>” shape. A crushing component for rotating extrusion and crushing of rubber is arranged between the two guide plates 13; a secondary crushing box 17 is arranged at the lower part of the cavity of the crushing box 1, and a cutting component 2 for further cutting and crushing the rubber is arranged in the secondary crushing box 17.

[0026] like Figure 2 As shown, the crushing assembly includes three groups of rotating columns 14 that are evenly spaced up and down and arranged between two guide plates 13. A feed pipe 18 with a gradually narrowing opening is fixedly installed at the bottom of the two groups of guide plates 13. A secondary crushing box 17 is fixedly installed on the wall of the crushing box 1 in an inclined state with the left side higher and the right side lower. The secondary crushing box 17 penetrates the right side wall of the crushing box 1. The secondary crushing box 17 is a hollow cylinder, and the output end of the feed pipe 18 is fixedly connected to the left side wall of the secondary crushing box 17.

[0027] like Figure 2 , Figure 5 , Figure 6As shown, a servo motor 15 is fixedly installed on the left outer wall of the crushing box 1, and the output end of the servo motor 15 passes through the left wall of the crushing box 1 through a bearing. The cutting assembly 2 includes a secondary crushing column 19 fixedly connected to the output end of the servo motor 15, and the secondary crushing column 19 is parallel to the secondary crushing box 17. The right end of the secondary crushing column 19 is rotatably connected to the right wall of the secondary crushing box 17 through a bearing. A plurality of groups of crushing disks 40 distributed at equal intervals are fixedly inserted on the outer wall of the secondary crushing column 19, and the circumferential edge of the crushing disk 40 is conical. Uniformly distributed cutting protrusions 41 are fixedly installed on the outer wall of each crushing disk 40; the cutting protrusions 41 on two adjacent crushing disks 40 are staggered.

[0028] like Figure 2 , Figure 3 , Figure 4 As shown, a discharge cover 21 is fixedly installed at the right bottom of the secondary crushing box 17. The distribution state of the three groups of rotating columns 14 is in the shape of ">". The number of rotating columns 14 in each group is two. The six rotating columns 14 are all provided with uniformly distributed extrusion structures 3. The conical cone block B38 is fixedly installed on the side wall surface where the two guide plates 13 are close to each other. The six rotating columns 14 are all connected to the front and rear side walls of the cavity of the crushing box 1 through the shaft rod. The six rotating columns 14 are all driven by the rotating motor, and the rotating motor is installed on the wall surface of the crushing box 1 through the bracket. The extrusion structure 3 includes an extrusion block 31, the cross section of the extrusion block 31 is pentagonal, and one side wall surface of the extrusion block 31 is fixedly installed on the outer wall of the rotating column 14; the extrusion block 31 is provided with an elastic extrusion and telescopic extrusion protrusion 32 on the side inclined surface away from the rotating column 14. The extrusion protrusion 32 is a cylinder and one end of the extrusion protrusion 32 is in an arc-shaped protrusion state. The arc-shaped protrusion end of the extrusion protrusion 32 is located outside the inclined surface of the extrusion block 31. The cylindrical end of the extrusion protrusion 32 is fixedly installed with a limit plate 35, and a limit groove 36 that is movably engaged with the limit plate 35 is provided on the outer wall of the inclined surface of one side of the extrusion block 31. The limit plate 35 is movably engaged in the limit groove 36. The arc-shaped protrusion end of the extrusion protrusion 32 movably penetrates the inner wall of the inclined surface of the extrusion block 31, and a spring 37 is fixedly installed in the inner wall of the limit groove 36. A permanent magnet 33 is fixedly installed in the wall surface of the arc-shaped protrusion end of the extrusion protrusion 32, and evenly distributed cone blocks A34 are fixedly installed on the arc-shaped outer wall of the extrusion protrusion 32. The extrusion protrusions 32 on the two rotating columns 14 of each group are installed in opposite states.

[0029] The rubber is then squeezed and crushed by the extrusion block 31. After the rubber is squeezed and crushed by the two rotating columns 14 corresponding to each group, the rubber flows downward and is squeezed and crushed for the second time between the two rotating columns 14 in the middle, and finally falls between the two rotating columns 14 in the last group for squeezing and crushing. The utility model provides three groups of rotating columns 14 in a “>” trend, and the number of rotating columns 14 in each group is two in the horizontal direction, so as to realize the three-way squeezing and crushing of the rubber entering between the two guide plates 13 from top to bottom, thereby improving the extrusion and crushing efficiency of the rubber of the utility model. In addition, a conical cone block B38 is fixedly installed on the side wall where the two guide plates 13 are close to each other. The cone block B38 cooperates with the extrusion block 31 to extrude the rubber, thereby ensuring that the rubber can be completely crushed. The utility model sets an extrusion structure 3. When the six groups of rotating columns 14 drive the corresponding extrusion blocks 31 to rotate and extrude the rubber, the extrusion protrusions 32 also rotate with the extrusion blocks 31. The cone block A34 on the outer wall of the extrusion protrusion 32 further extrudes and crushes the rubber. At the same time, the extrusion protrusions 32 on each group of rotating columns 14 are distributed in opposite states, which further improves the rubber crushing efficiency of the utility model.

[0030] The extrusion protrusion 32 of the utility model can squeeze and contract the spring 37 through the limit plate 35, so that the extrusion protrusion 32 can play a certain extrusion buffering role, and play a role in protecting the extrusion block 31 and the extrusion protrusion 32. When the two rotating columns 14 rotate so that the permanent magnets 33 on the extrusion protrusion 32 are close to each other, under the magnetic repulsion of the permanent magnets 33, the extrusion protrusion 32 can be contracted to a certain extent, which avoids the problem of rubber crushing and getting stuck, and ensures that the rubber can fall smoothly after being squeezed and crushed. The squeezed and crushed rubber is poured into the secondary crushing box 17 through the feeding pipe 18, and the working switch of the servo motor 15 is turned on.

[0031] Furthermore, when the rubber crushed above falls into the secondary crushing box 17, the secondary crushing column 19 is driven to rotate by the servo motor 15, and the secondary crushing column 19 can drive multiple groups of crushing discs 40 to rotate synchronously. When the crushing discs 40 rotate, the tapered edge of the crushing discs 40 can cut the rubber, and the rubber falling between the two adjacent crushing discs 40 can be further cut and crushed by the cutting protrusions 41, and the rubber is completely cut into a small state; finally, the rubber body after cutting and crushing can be automatically discharged through the discharge cover 21.

In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
