Description

Technical Field

[0001] This application relates to the field of automotive injection molded parts recycling technology, and in particular to a recycling and processing device for automotive injection molded parts. Background Technology

[0002] The current recycling process for automotive injection molded parts generally adopts a segmented, independent operation mode: first, large injection molded parts are crushed by external crushing equipment, then the crushed fragments are transferred to special cleaning equipment to remove surface contaminants, then transferred to centrifugal or drying equipment to dehydrate and dry, and finally enter the subsequent sorting stage.

[0003] Traditional segmented processing solutions have gradually revealed several intractable pain points in practical operation: First, the independent deployment of multiple devices results in a large overall footprint, high equipment procurement and maintenance costs, and the transfer of materials between different devices not only significantly extends the processing cycle but also easily leads to material spillage and secondary pollution, making it difficult to further improve overall processing efficiency. Second, the surface of automotive injection molded parts is often covered with complex contaminants such as paint, adhesive, and oil stains. Traditional static immersion cleaning makes it difficult for debris to fully contact the cleaning agent, resulting in unstable cleaning effects and the purity of the subsequently produced recycled materials failing to meet the standards for the reuse of automotive parts.

Then, the automotive injection molded parts are placed on the top of the processing cylinder, and the drive motor is started. The rotation of the drive motor drives a rotating shaft and a crushing roller to rotate. The rotation of the rotating shaft drives another crushing roller to rotate under the action of two transmission gears, so that the two crushing rollers rotate towards the center at the same time, realizing the automatic crushing of the automotive injection molded parts. At the same time, the crushed fragments fall into the... Inside the rotating screen drum, a rotating motor is started.

[0026] 2. The automotive injection molded parts recycling and processing device described in this application, by setting up a dust removal mechanism, during the process of the drive motor driving two crushing rollers to rotate in opposite directions, the rotation of the rotating shaft can drive the reciprocating threaded column to rotate under the action of two bevel gears. The rotation of the reciprocating threaded column drives the rectangular plate to move up and down reciprocally, thereby driving the sealing plate to move up and down reciprocally through the connecting rod. When the sealing plate moves upward, it can suck away the air in the dust collection box through the suction pipe, so that the dust collection box can suck air into the interior of the two rotating shafts through the Y-shaped dust suction pipe. Thus, it can absorb the dust generated during the crushing of the injection molded parts through several dust suction channels and collect it through the dust collection box. When the sealing plate moves downward, it can force the air in the rectangular box into the dust collection box through the suction pipe, increasing the air pressure in the dust collection box.

A drain valve is provided on the surface of the drain pipe 307.

[0034] Specifically, professional industrial cleaning agent can be injected into the bottom of the treatment cylinder 100 through the inlet pipe 306, and at the same time, the professional industrial cleaning agent can be discharged through the outlet pipe 307.

At the same time, the crushed fragments fall into the rotating screen cylinder 302. Inside, the rotary motor 304 is started, and the rotation of the rotary motor 304 drives the active gear disc 308 to rotate. The rotation of the active gear disc 308 drives the driven gear disc 309 and the discharge pipe 303 to rotate, thereby driving the rotating screen cylinder 302 to rotate.

[0042] Please refer to this carefully. Figure 6 , Figure 8 A rectangular plate 507 and a sealing plate 508 are slidably disposed on the inner wall of the rectangular box 504. The upper surface of the rectangular plate 507 is provided with a threaded hole that is threaded to the outer surface of the reciprocating threaded column 505. Two symmetrical connecting rods 509 are fixedly disposed on the lower surface of the rectangular plate 507, and the bottom ends of the two connecting rods 509 are fixedly connected to the upper surface of the sealing plate 508.

[0043] Specifically, the reciprocating threaded column 505 can drive the rectangular plate 507 to move up and down automatically, thereby driving the sealing plate 508 to move up and down automatically via the connecting rod 509.

[0044] Please refer to this carefully. Figure 6 , Figure 8 The bottom of the rectangular box 504 is provided with a suction pipe 5010. One end of the suction pipe 5010 extends to the inner bottom of the rectangular box 504, and the other end of the suction pipe 5010 away from the rectangular box 504 extends to the inner bottom of the dust collection box 503.

[0045] Specifically, the suction pipe 5010 can be used to extract and inject air into the dust collection box 503.

[0046] Please refer to this carefully. Figure 6 , Figure 8 The front of the dust collection box 503 is provided with a Y-shaped suction tube 5011. One end of the Y-shaped suction tube 5011 extends into the interior of the dust collection box 503, and the other two ends of the Y-shaped suction tube 5011 extend into the interior of two rotating shafts 201 respectively.

[0049] Specifically, the dust can be discharged through the dust discharge pipe 5013 into the professional industrial cleaning agent at the bottom of the treatment cylinder 100.

[0050] In this embodiment, by setting up a dust removal mechanism 500, during the process of the drive motor 203 driving the two crushing rollers 202 to rotate in opposite directions, the rotation of the rotating shaft 201 can drive the reciprocating threaded column 505 to rotate under the action of the two bevel gears 506. The rotation of the reciprocating threaded column 505 drives the rectangular plate 507 to move up and down reciprocally, thereby driving the sealing plate 508 to move up and down reciprocally through the connecting rod 509. When the sealing plate 508 moves upward, it can suck away the air in the dust collection box 503 through the suction pipe 5010, so that the dust collection box 503 can suck away the air in the two rotating rollers through the Y-shaped suction pipe 5011. The moving shaft 201 draws air in, allowing it to absorb dust generated during the crushing of injection molded parts through several dust collection channels 501. The dust is then collected in the dust collection box 503. When the sealing plate 508 moves downward, it forces the air in the rectangular box 504 into the dust collection box 503 through the suction and discharge pipe 5010, increasing the air pressure in the dust collection box 503. This allows the dust in the dust collection box 503 to be discharged through the dust discharge pipe 5013 into the professional industrial cleaning agent at the bottom of the processing cylinder 100, achieving the purpose of automatic dust removal during crushing and preventing dust from polluting the environment.

[0051] Working principle: When recycling automotive injection molded parts, the professional industrial cleaning agent from the external tank is first delivered to the bottom of the processing cylinder 100 via the pump on the inlet pipe 306, ensuring that the cleaning agent submerges three-quarters of the rotating screen cylinder 302. Then, the automotive injection molded parts are placed on top of the processing cylinder 100, and the drive motor 203 is started. The rotation of the drive motor 203 drives a rotating shaft 201 and a crushing roller 202. The rotation of the rotating shaft 201, under the action of two transmission gear discs 204, drives the other crushing roller 202 to rotate, thus causing both crushing rollers 202 to rotate simultaneously towards the center, achieving automatic crushing of the automotive injection molded parts. Simultaneously, the pulverized fragments fall into the rotating screen cylinder 302, and the rotating motor 304 is started. The rotation of the rotating motor 304 drives the active gear disc 308 to rotate, which in turn drives the driven gear disc 309 and the discharge pipe 303 to rotate, thereby causing the rotating screen cylinder 302 to rotate. Under the action of the stirring blades 305, the fragments inside the rotating screen cylinder 302 are automatically stirred, achieving the purpose of automatically removing contaminants from the pulverized fragments. Moreover, after the contaminant removal is completed, the drain valve can be opened to discharge the waste liquid. After the waste liquid is discharged, when the rotating motor 304 drives the rotating screen cylinder 302 to rotate, the fragments inside the rotating screen cylinder 302 can be centrifugally dried. This device integrates crushing, decontamination, and drying in the recycling of automotive injection molded parts, effectively improving processing efficiency and reducing equipment footprint and cost. Furthermore, during the process of the drive motor 203 driving the two crushing rollers 202 to rotate in opposite directions, the rotation of the rotating shaft 201, under the action of the two bevel gears 506, drives the reciprocating threaded column 505 to rotate. The rotation of the reciprocating threaded column 505 causes the rectangular plate 507 to move up and down reciprocally, which in turn drives the sealing plate 508 to move up and down reciprocally via the connecting rod 509. When the sealing plate 508 moves upward, it can suck away the air from the dust collection box 503 through the suction pipe 5010. The dust collection box 503 draws air from the inside of the two rotating shafts 201 through the Y-shaped suction pipe 5011, thereby absorbing the dust generated during the crushing of injection molded parts through several suction channels 501 and collecting it through the dust collection box 503. When the sealing plate 508 moves downward, it can force the air in the rectangular box 504 into the dust collection box 503 through the suction and discharge pipe 5010, increasing the air pressure in the dust collection box 503. This allows the dust in the dust collection box 503 to be discharged into the professional industrial cleaning agent at the bottom of the processing cylinder 100 through the dust discharge pipe 5013, achieving the purpose of automatic dust removal of the dust generated during crushing and avoiding dust pollution to the environment.
