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, it is easy to cause uneven stress distribution in the crushing cavity, causing 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

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, purposes and effects realized by the application easy to understand, the application is further described below in combination with specific embodiments.

[0036] Embodiment one: as Figures 1 to 9As shown, the rubber recycling particle preparation device provided by the embodiment of the application comprises a body 1, one side of the body 1 is fixedly connected with a fixed motor 21, an upper portion of the body 1 is provided with a fixed frame 2, two groups of crushing assemblies are rotatably arranged in the fixed frame 2, the crushing assembly comprises a crushing roller 25, the crushing roller 25 is driven by the fixed motor 21 to perform crushing work, one side of the fixed frame 2 is provided with an inlet, one side of the fixed frame 2 is rotatably connected with a plurality of auxiliary plates 22, the auxiliary plates 22 correspond to the inlet, a top wall of the fixed frame 2 is fixedly connected with a partition plate 23, one side of the partition plate 23 is provided as a first cavity 24, the other side of the partition plate 23 corresponds to the inlet, one side of the fixed frame 2 is fixedly connected with a positioning frame 3, the positioning frame 3 is provided with a pretreatment assembly, the pretreatment assembly comprises a discharging frame 32 fixedly connected to an upper surface of the positioning frame 3, a discharging groove 34 is formed in the discharging frame 32, two connecting motors 33 are fixedly connected to one side of the discharging frame 32, an auxiliary paddle 35 is fixedly connected to an output end of the connecting motor 33, and the auxiliary paddle 35 is made of hard plastic material;

[0037] The auxiliary assembly further comprises a cavity in the positioning frame 3, the cavity in the positioning frame 3 stores salt water, and after the waste rubber material is discharged into the positioning frame 3, the salt water is used to separate the stones from the rubber;

[0038] A first hydraulic cylinder 31 is fixedly connected to a bottom surface of the positioning frame 3, an 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 a surface of the push plate 313.

[0039] Specifically, in the rubber recycling particle preparation process, when the existing equipment processes 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 easy to cause 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 recycled particles and product quality. More seriously, 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 recycled rubber.

[0040] Therefore, the application solves the above problems by the above structure. First, the waste rubber is poured into the feeding groove 34 in the feeding frame 32, and then the waste rubber and the stones are hit by the auxiliary paddle 35 in the feeding frame 32 into 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 wall of the feeding 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 hole 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. In the moving process, the feeding assembly pushes the separated waste rubber into the fixed frame 2. After entering the fixed frame 2, the fixed motor 21 is started to drive a plurality of crushing rollers 25 to perform crushing work. In 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.

[0041] 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.

[0042] As shown in Figure 8 The feeding assembly of the present embodiment includes a reciprocating screw 315 rotatably arranged in the push plate 313. One end of the reciprocating screw 315 is fixedly connected with a fixed gear 316. A rack plate 317 is fixedly connected with the position corresponding to the fixed gear 316 on the inner wall of the positioning frame 3. The rack plate 317 is engaged with the fixed gear 316. The circumferential surface of the reciprocating screw 315 is slidably connected with a convex plate 324. The upper surface of the convex plate 324 is fixedly connected with a vertical plate 326. One side of the vertical plate 326 is fixedly connected with an inclined plate 318. A plurality of inclined holes 319 are formed in the surface of the inclined plate 318.

[0043] Specifically, when the separation is completed, the first hydraulic cylinder 31 drives the push plate 313 to move upward, which drives the fixed gear 316 at the end of the reciprocating screw 315 to rotate along the rack plate 317, thereby driving the reciprocating screw 315 to rotate. The rotation of the reciprocating screw 315 drives the convex plate 324 on the circumferential surface of the reciprocating screw 315 to slide along the reciprocating screw 315, thereby driving the vertical plate 326 on the upper surface of the convex plate 324 and the inclined plate 318 on one side of the vertical plate 326 to move obliquely towards the fixed frame 2, and the separated waste rubber is sent into the positioning frame 3 for crushing and granulating work;

[0044] The push plate 313 is driven to move up by the first hydraulic cylinder 31, the meshing of the fixed gear 316 and the rack plate 317 drives the reciprocating screw 315 to rotate, and then drives the convex plate 324 to slide, so that the vertical plate 326 and the inclined plate 318 move obliquely to feed, without additional power source, energy is saved and cost is reduced, the inclined hole 319 on the inclined plate 318 can further filter small impurities during the feeding process, and the purity of the rubber is improved, meanwhile, the assembly realizes the coherent operation of separation and feeding, the degree of automation is high, manual intervention is reduced, the production efficiency is improved, and the smoothness and stability of the preparation process of the waste rubber recycling and regeneration particles are ensured.

[0045] As shown in Figure 7 The positioning frame 3 is provided with a guide groove 311 close to one side of the fixed frame 2, the bottom wall of the guide groove 311 is fixedly connected with a guide plate 312, one side of the positioning frame 3 close to the guide plate 312 is provided with a sealing element, and the sealing element prevents the waste rubber from falling into the guide groove 311 during feeding.

[0046] The sealing element comprises two telescopic rods 37 fixedly connected to the upper surface of the positioning frame 3, the circumferential surfaces of the two telescopic rods 37 are sleeved with springs 36, the top ends of the two springs 36 and the telescopic rods 37 are fixedly connected with a same top plate 38, the lower surface of the top plate 38 is fixedly connected with a limiting plate 39, the limiting plate 39 is used for separating the positioning frame 3 and the guide plate 312, and the lower surface of the top plate 38 is further fixedly connected with two vertical rods 310, and the lengths of the vertical rods 310 are greater than that of the limiting plate 39.

[0047] Specifically, during the upward lifting of the push plate 313, the two vertical rods 310 on the lower surface of the top plate 38 are also lifted upward, the two vertical rods 310 lift the top plate 38, thereby driving the limiting plate 39 to move upward, the limiting plate 39 opens the feeding opening between the positioning frame 3 and the fixed frame 2 when moving upward, and the upward movement of the push plate 313 also indirectly drives the inclined plate 318 and the vertical plate 326 to move towards the fixed frame 2, thereby pushing the separated waste rubber to fall into the fixed frame 2 along the guide plate 312 from the opened feeding opening.

[0048] Through the setting of the guide groove 311 and the guide plate 312, a precise path is provided for the waste rubber to enter the fixed frame 2, ensuring smooth feeding, and the design of the sealing element, through the cooperation of the telescopic rod 37, the spring 36 and the top plate 38, the limiting plate 39 can effectively close the feeding opening in the normal state, preventing the rubber from falling into the guide groove 311, and the lengths of the vertical rods 310 are greater than that of the limiting plate 39, ensuring that the feeding opening is opened first when being lifted, the push plate 313 is lifted, the vertical rod 310, the top plate 38 and the limiting plate 39 are simultaneously driven to move, the feeding opening is automatically opened, then the spring 36 can make the limiting plate 39 automatically reset, at the same time, the inclined plate 318 and the vertical plate 326 push the rubber to fall along the guide plate 312, the whole process is coherent and efficient, reduces material loss, and improves the degree of production automation and stability.

[0049] Embodiment two: as shown in Figures 1 to 9 Another embodiment of the application is shown in Comparative Embodiment One, wherein a mixing assembly is further arranged between the inclined plate 318 and the vertical plate 326. The mixing assembly comprises an inclined groove 327 formed on one side of the inner wall of the positioning frame 3, and a gear 328 fixed to the inner wall of the inclined groove 327. A support frame 320 is fixed to one side of the vertical plate 326, and an auxiliary shaft 325 is rotatably connected to the middle part of the support frame 320. A plurality of rotating plates 321 are fixed to the circumferential surface of the auxiliary shaft 325, and a rotating hole 322 is formed on the circumferential surface of each rotating plate 321. A rotating gear 323 is fixed to one end of the auxiliary shaft 325, and the rotating gear 323 is engaged with the gear 328 in the inclined groove 327.

[0050] Specifically, during the process of lifting the inclined plate 318 and the vertical plate 326 by the push plate 313, the inclined plate 318 and the vertical plate 326 are driven by the reciprocating screw 315 and the first hydraulic cylinder 31 to move obliquely along the inclined groove 327. At this time, the inclined plate 318 and the vertical plate 326 not only push the waste rubber floating in the brine into the fixed frame 2, but also make the rotating gear 323 rotate along the gear 328 in the inclined groove 327 during the feeding process, thereby driving the auxiliary shaft 325 to rotate and driving the rotating plates 321 on the circumferential surface of the auxiliary shaft 325 to mix the newly added salt.

[0051] By cleverly utilizing the structure linkage when the inclined plate 318 and the vertical plate 326 move obliquely to push the material, the rotating gear 323 is made to rotate along the gear 328 in the inclined groove 327, driving the auxiliary shaft 325 and the rotating plates 321 to work without the need for additional power, saving energy and cost. The rotating plates 321 mix the newly added salt, which can make the salt quickly and uniformly dispersed in the brine, improve the effect of separating the waste rubber and stone impurities from the brine, and ensure the quality of subsequent rubber recycling. Moreover, the whole process is synchronized with the feeding, and the mixing of salt is realized at the same time as the pushing of the material, improving the coherence and efficiency of the production process, making the whole rubber recycling and regenerating particle preparation device run more efficiently and stably.

[0052] The working principle is that first, the waste rubber is poured into the feeding groove 34 in the feeding frame 32, and then the waste rubber and the stones are hit into the brine in the positioning frame 3 through the auxiliary paddle 35 in the feeding frame 32. 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 wall of the feeding frame 32, and then the density of the brine is used to separate the stones and the waste rubber. The separated stones sink to the bottom and fall into the bottom wall of the positioning frame 3 through the fixed hole 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. In the moving process, the feeding assembly pushes the separated waste rubber into the fixed frame 2. After entering the fixed frame 2, the fixed motor 21 is started to drive a plurality of crushing rollers 25 to perform crushing work. In 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.

[0053] The specific process is that when the separation is completed, the first hydraulic cylinder 31 drives the push plate 313 to move upward, which drives the fixed gear 316 at the end of the reciprocating screw 315 to rotate along the rack plate 317, thereby driving the reciprocating screw 315 to rotate. The rotation of the reciprocating screw 315 drives the convex plate 324 on the circumference to slide along the reciprocating screw 315, thereby driving the vertical plate 326 on the upper surface of the convex plate 324 and the inclined plate 318 on one side of the vertical plate 326 to move obliquely towards the fixed frame 2, and the separated waste rubber is fed into the positioning frame 3 for crushing and granulating work.

[0054] The first hydraulic cylinder 31 drives the push plate 313 to move upward, and the fixed gear 316 and the rack plate 317 are engaged to make the reciprocating screw 315 rotate, thereby driving the convex plate 324 to slide and making the vertical plate 326 and the inclined plate 318 move obliquely to feed. No additional power source is needed, energy is saved and cost is reduced. The inclined hole 319 on the inclined plate 318 can further filter small impurities during the feeding process, improving the purity of the rubber. At the same time, this assembly realizes the consecutive operation of separation and feeding, has high automation degree, reduces manual intervention, improves production efficiency, and guarantees the smoothness and stability of the waste rubber recycling and regeneration particle preparation process.

[0055] In addition, in the process of lifting the push plate 313 upward, the two vertical rods 310 on the lower surface of the top plate 38 are also lifted upward, which lifts the top plate 38, thereby driving the limiting plate 39 to move upward, which opens the feeding opening 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 towards the fixed frame 2, thereby pushing the separated waste rubber to fall into the fixed frame 2 along the guide plate 312 through the opened feeding opening.

[0056] The precise path for the waste rubber into the fixed frame 2 is provided by the arrangement of the guide groove 311 and the guide plate 312, so as to ensure smooth feeding, and the sealing member is designed, and the limiting plate 39 can effectively close the feeding port in the normal state through the cooperation of the telescopic rod 37, the spring 36 and the top plate 38, so as to prevent the rubber from falling into the guide groove 311, and the length of the vertical rod 310 is greater than that of the limiting plate 39, so as to ensure that the feeding port is opened first when the vertical rod 310 is lifted, and the push plate 313 is lifted, and the vertical rod 310, the top plate 38 and the limiting plate 39 are driven synchronously, so as to realize automatic opening of the feeding port, and then the spring 36 can make the limiting plate 39 automatically reset, and the inclined plate 318 and the vertical plate 326 push the rubber to fall along the guide plate 312, so that the whole process is coherent and efficient, the material loss is reduced, and the production automation degree and stability are improved.

[0057] Finally, during the lifting process of the inclined plate 318 and the vertical plate 326 by the push plate 313, the inclined plate 318 and the vertical plate 326 are driven by the reciprocating screw 315 and the first hydraulic cylinder 31 to move obliquely along the inclined groove 327, so that the waste rubber floating in the brine is not only pushed into the fixed frame 2, but also makes the rotating gear 323 rotate along the tooth 328 in the inclined groove 327, so as to drive the auxiliary shaft 325 to rotate, and drive the rotating plate 321 on the circumference of the auxiliary shaft 325 to mix the newly added salt;

[0058] When the inclined plate 318 and the vertical plate 326 are obliquely moved to push the material, the rotating gear 323 is driven to rotate along the tooth 328 in the inclined groove 327 by the ingenious use of structure linkage, so as to drive the auxiliary shaft 325 and the rotating plate 321 to work without additional power, thereby saving energy and cost, the rotating plate 321 mixes the newly added salt, so that the salt is quickly and uniformly dispersed in the brine, the effect of separating the waste rubber and the hard substances such as stones in the brine is improved, the rubber recycling quality is guaranteed, and the whole process is synchronized with the feeding, so that the feeding and the mixing of the salt are realized at the same time, the coherence and efficiency of the production process are improved, and the whole rubber recycling and regenerating particle preparation device runs more efficiently and stably.

[0059] The present application can effectively improve the purity of waste rubber by separating waste rubber and hard substances such as stones in the brine, so as to improve the quality of waste rubber granulation, and the reduction of hard substances such as stones greatly improves the service life of the recycling equipment.
