Description

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under very small external forces, and can return to its original state after removing the external forces. Rubber belongs to a completely amorphous polymer. In the process of rubber production, a grinding device is needed to grind waste rubber into powder for recycling.

[0003] For example, the utility model with the application number CN202020966442.2 discloses a raw material grinding and mixing device for rubber production. Through the setting of the hopper, the raw materials can be conveniently placed, and then with the cooperation of the guide cylinder, the raw materials are sent to the feed hopper on the grinding disc, which is convenient for the subsequent grinding work. Through the setting of the fixed rod, the bearing turntable can be fixed, and the bearing turntable can support the grinding disc with the cooperation of the guide cylinder, which is convenient for its rotation, and the degree of mechanization is high. However, in the actual use of this type of device, when there are too large rubber particles in the raw material particles, the too large rubber particles are not easy to flow out from the outer end of the auxiliary disc, and they will also block other rubber particles, resulting in the problem of affecting the overall grinding efficiency.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a grinding device with a pre-impurity removal mechanism is provided. Content of the Utility Model

[0005] The purpose of the utility model is to provide a grinding device with a pre-impurity removal mechanism to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A grinding device with a pre-impurity removal mechanism includes a cylinder body and a sieve plate. A cylinder cover is arranged at the top of the cylinder body, and a crushing component is arranged in the center of the top of the cylinder cover. Two ends of the bottom of the cylinder cover are fixed with mounting plates, and a magnetic attraction rod is arranged between the mounting plates, and the magnetic attraction rod is spiral. The upper end inside the cylinder body is slidably connected with a supporting frame, the sieve plate is arranged inside the supporting frame. A fixed seat is arranged inside the lower end of the cylinder body, and a grinding plate is arranged on the top of the fixed seat. A driving motor is arranged on one side of the cylinder body, and one end of the driving motor is connected with a driving gear. A gear ring is meshed with one side of the driving gear, and a grinding ring is fixed at the bottom of the gear ring.

[0007] Further, the crushing component includes a crushing frame and a crushing motor. The crushing frame is fixed at the top of the cylinder body, and a crushing motor is arranged on one side of the crushing frame.

[0008] Furthermore, the crushing assembly further includes a crushing roller and a synchronous gear. One end of the crushing motor is connected to the crushing roller, and a synchronous gear is arranged at the end of the crushing roller.

[0009] Furthermore, the number of the crushing rollers and the synchronous gears is both set to two, and the two crushing rollers are connected by synchronous gears for transmission.

[0010] Furthermore, a vibration assembly is arranged at the top of the grinding ring. The vibration assembly includes a top rod and a ball. The top of the grinding ring is connected to the top rod, and a ball is fitted at the top of the top rod.

[0011] Furthermore, the vibration assembly further includes a convex block and a limiting rod. A convex block is arranged at the top of the ball, and the convex block is triangular. The outer end of the top of the supporting frame is slidably connected to the limiting rod.

[0012] Furthermore, the convex block is fixedly connected to the supporting frame, and the convex blocks are evenly distributed in a circumferential manner about the bottom of the supporting frame.

[0013] Furthermore, the limiting rod is fixedly connected to the cylinder body, and the cylinder body is rotatably connected to the grinding ring.

[0014] The utility model provides a grinding device with a pre-removing impurity mechanism, having the following beneficial effects:

[0015] 1. Through the arrangement of the sieve plate in the utility model, after adding the material particles into the cylinder body, the sieve plate will block some over-sized rubber particles, avoiding the influence on the grinding efficiency due to over-sized material particles. At the same time, the crushing motor will drive the two crushing rollers through the synchronous gears to crush the material particles, further reducing the size of the material particles, thereby improving the subsequent grinding effect. Moreover, the magnetic attraction rods on the mounting plate can be used to absorb some metal particles mixed in the material particles, and the spiral magnetic attraction rods can increase the adsorption area, so as to pre-remove impurities from the material, which is beneficial to improving the quality of the ground rubber particles;

[0016] 2. Through the arrangement of the vibration assembly in the utility model, when the driving motor drives the grinding ring to rotate through the driving gear and the gear ring, it will also drive the top rod to move synchronously. At the same time, the limiting rod is used to prevent the supporting frame from rotating. At this time, the supporting frame will move downward under the action of gravity. Therefore, during the movement of the top rod, it will also squeeze the supporting frame through the convex block to make it move up and down. Moreover, the ball can be used to reduce the frictional loss at the top of the top rod, so that the sieve plate can vibrate up and down without adding an additional power source, preventing the influence on the material passing efficiency due to the blockage of the sieve plate.

The number of both the crushing rollers 303 and the synchronous gears 304 is two, and the two crushing rollers 303 are drivingly connected through the synchronous gears 304. The crushing motor 302 will use the synchronous gears 304 to make the two crushing rollers 303 crush the material particles, further reducing the size of the material particles, so as to improve the effect during subsequent grinding. Both ends of the bottom of the cylinder cover 2 are fixed with mounting plates 4, and a magnetic attraction rod 5 is arranged between the mounting plates 4, and the magnetic attraction rod 5 is spiral. The magnetic attraction rod 5 on the mounting plate 4 is used to absorb some metal particles mixed in the material particles, and the spiral magnetic attraction rod 5 is used to increase the adsorption area, so as to pre-remove impurities from the material, which is beneficial to improving the quality of the rubber particles after grinding. The upper end inside the cylinder body 1 is slidably connected with a supporting frame 6, and the sieve plate 7 is arranged inside the supporting frame 6. The sieve plate 7 will block some rubber particles that are too large to avoid affecting the grinding efficiency due to the oversize of the material particles.

A driving motor 10 is arranged on one side of the cylinder body 1, and one end of the driving motor 10 is connected to a driving gear 11. A gear ring 12 is meshed with one side of the driving gear 11, and a grinding ring 13 is fixed to the bottom of the gear ring 12.

The push rod 1401 is connected to the top of the grinding ring 13, and the ball 1402 is fitted into the top of the push rod 1401. When the drive motor 10 drives the grinding ring 13 to rotate through the driving gear 11 and the gear ring 12, it will also drive the push rod 1401 to move synchronously, and the ball 1402 can be used to reduce the frictional loss at the top of the push rod 1401.
