Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of non-metallic waste and scrap processing, in particular to a rubber recycling and regenerating particle preparation device. BACKGROUND

[0002] Rubber has high elasticity and high toughness, and can quickly recover to its original state after a large deformation, and is widely used in the fields of automobile tires, conveyor belts, shock absorption and sealing. However, due to such widespread application, rubber products become black garbage more harmful than white garbage after being discarded. At the same time, the production of rubber is limited, and under this background, the use of recycling and regenerating particle preparation equipment of recycled rubber is widely applied.

[0003] A patent with publication number CN118024454B discloses a rubber recycling and regenerating particle preparation equipment, which includes a crushing device for crushing rubber, a forming device arranged beside the crushing device for further crushing the rubber powder, and a devulcanization device arranged on the forming device for devulcanizing the rubber particles. The crushing device and the forming device provided in the application crush the rubber multiple times, soften the crushed rubber, facilitate the molding of the rubber particles, and finally devulcanize the rubber, with high automation degree. The forming device repeatedly grinds the rubber through the upper grinder and the lower grinder, finally extrudes the rubber into the outlet hole, and cuts the rubber into particles through the cutting rotary knife.

[0004] In the process of preparing rubber recycling and regenerating particles, the existing equipment will have hard impurities such as stones and metal scraps mixed in the material when processing waste rubber. In the crushing link, the high-hardness stones will directly impact the crushing cutter, causing the blade to break, crack or severe wear, greatly shortening the service life of the cutter, increasing the frequency of equipment downtime and the cost of spare parts. Secondly, when hard impurities and rubber are mixed and crushed, due to the large difference in hardness between the two, uneven stress distribution in the crushing cavity is easy to cause, which causes the equipment to vibrate intensively, the bearing to wear out quickly, and even the transmission components to break down, threatening production safety. In addition, stones that have not been effectively separated will block the filter screen during the melting and extrusion stage, causing abnormal fluctuations in equipment pressure, forcing the production line to frequently stop for cleaning, reducing production efficiency, and possibly causing rubber degradation due to local overheating, affecting the physical properties of the regenerated particles and product quality. More seriously, fine stone powder mixed into the finished product particles will reduce the elasticity, wear resistance and other key indicators of rubber, limiting its application in high-end products, and ultimately affecting the market competitiveness and economic benefits of recycled rubber.

[0005] Therefore, the application provides a rubber recycling and regenerating particle preparation device. SUMMARY

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

The auxiliary assembly further comprises a cavity inside the positioning frame 3, and brine is stored in the cavity inside the positioning frame 3; after the waste rubber material is discharged into the positioning frame 3, the salt water is used to separate the stones from the rubber; The bottom surface of the positioning frame 3 is fixedly connected with a first hydraulic cylinder 31, and the output end of the first hydraulic cylinder 31 is fixedly connected with a push plate 313, and a plurality of fixing holes 314 are formed in the surface of the push plate 313.

[0024] Specifically, in the process of preparing the rubber recycling and regenerating particles, when the existing equipment processes the waste rubber, hard impurities such as stones and metal scraps are mixed in the material. In the crushing link, the high-hardness stones will directly impact the crushing cutter, causing the blade to break, crack or severe wear, greatly shortening the service life of the cutter, increasing the frequency of equipment downtime and the cost of spare parts. Secondly, when the hard impurities and the rubber are mixed and crushed, due to the large difference in hardness between the two, uneven stress distribution in the crushing cavity is easily caused, which leads to the intensification of equipment vibration, the acceleration of bearing wear, and even mechanical failures such as transmission component fracture, threatening production safety. In addition, the stones that are not effectively separated will block the filter screen during the melting and extrusion stage, causing abnormal fluctuations in the equipment pressure, forcing the production line to frequently stop for cleaning, reducing production efficiency, and possibly causing rubber degradation due to local overheating, affecting the physical properties of the regenerated particles and product quality. More seriously, the fine stone powder mixed into the finished particles will reduce the elasticity and wear resistance of the rubber, limiting its application in high-end products, and ultimately affecting the market competitiveness and economic benefits of the regenerated rubber. Therefore, the present application solves the above problems by setting the above structure. First, the waste rubber is poured into the discharge chute 34 in the discharge frame 32, and then the waste rubber and stones are hit by the auxiliary paddle 35 in the discharge frame 32 and enter the brine in the positioning frame 3. The hitting of the auxiliary paddle 35 is used to separate the stones mixed in the waste rubber. The auxiliary paddle 35 is driven by the two connecting motors 33 outside the discharge frame 32, and then the density of the brine is used to separate the stones and the waste rubber. The stones sink to the bottom and fall into the bottom wall of the positioning frame 3 through the fixed holes 314 on the surface of the push plate 313. Then the push plate 313 moves upward under the drive of the first hydraulic cylinder 31. During the movement, the waste rubber after separation is pushed into the fixed frame 2 by the feeding assembly. After entering the fixed frame 2, the fixed motor 21 is started to drive a plurality of crushing rollers 25 to perform the crushing work. During the crushing process, the dust particles generated will flow into the first cavity 24, reducing the dust particles flowing out of the fixed frame 2 and polluting the working environment. By using brine to separate waste rubber and hard substances such as stones, the purity of waste rubber can be effectively improved, the quality of waste rubber granulation is improved, and the service life of the recycling equipment is greatly improved due to the reduction of hard substances such as stones.

The two vertical rods (310) push up the top plate (38), thereby driving the limit plate (39) to move upward. The limit plate (39) moves upward to open the discharge port between the positioning frame (3) and the fixed frame (2). In addition, the upward movement of the push plate (313) also indirectly drives the inclined plate (318) and the vertical plate (326) to move toward the fixed frame (2), thereby pushing the separated waste rubber to fall from the opened discharge port along the guide plate (312) into the fixed frame (2).

9. The device for preparing rubber recycled particles according to claim 8, characterized in that: A mixing assembly is further provided between the inclined plate (318) and the vertical plate (326), and the mixing assembly includes an inclined groove (327) provided on one side of the inner wall of the positioning frame (3), and teeth (328) are fixedly connected to the inner wall of the inclined groove (327).
