Description

Technical Field

[0001] The present invention belongs to the technical field of recycling of thermoplastic waste materials, and more specifically, particularly relates to a recycling device for cracked waste materials of thermoplastic plastic products for automotive interior and exterior trims. Background Art

[0002] With the rapid development of the automotive industry, the production scale and output of automobiles are constantly expanding. A large number of thermoplastic plastic products are used for automotive interior and exterior trims. This is because thermoplastic plastics have advantages such as good formability, mechanical properties, and appearance quality, and can meet various requirements such as the aesthetics and comfort of automotive interiors and the strength and weather resistance of exterior trims. However, due to non-compliance with the mold temperature conditions and lack of material supply, some molded plastic products are unqualified, resulting in waste of injection molding materials. Therefore, it is necessary to recycle and reuse the waste materials.

[0003] The recycling of cracked waste materials of current thermoplastic plastic products for automotive interior and exterior trims still has the following deficiencies: Currently, when dealing with unqualified thermoplastic plastic products for automotive interior and exterior trims, the molded plastic products need to be placed and stored, and then the recycling process is carried out later. This makes the waste materials occupy a large space, and because the properties of the plastic are stable after cooling, it takes a long time to recycle and crush them.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a recycling device for cracked waste materials of thermoplastic plastic products for automotive interior and exterior trims is provided, with the expectation of achieving a more practical value.

[0007] Optionally, an auxiliary die is fixedly connected to the rear end position of the airtight detection member. The auxiliary die is located directly in front of the feeding die. A cylinder B is linearly connected to the lower end position of the airtight detection member. The cylinder B is fixedly connected to the middle position at the front end of the preparation seat. A push plate is fixedly connected to the rear end position of the cylinder B. The push plate is located at the front end position inside the groove of the preparation seat, and the push plate is located at the middle position at the front end of the top of the conveyor belt A.

[0008] Optionally, a rectangular collection box is placed at the lower position inside the extension frame. The swaying seat is located directly in front of the collection box.

[0009] Optionally, a rack is arranged at the lower position of the reciprocating frame. A support rod is fixedly connected to the middle position at the front end of the T-shaped frame. The support rod of the T-shaped frame is rotatably connected to the upper middle position of the transmission member. The top position of the transmission member is a sector gear, and a strip-shaped groove is formed at the lower end position of the transmission member. The sector gear at the top of the transmission member meshes with the rack at the lower part of the reciprocating frame.

[0010] Optionally, a servo motor is fixedly connected to the middle position at the rear end of the T-shaped frame. A turntable is rotatably connected to the front end position of the servo motor. A plug rod is arranged at the front end position of the turntable, and the plug rod of the turntable is located in the strip-shaped groove of the transmission member. The turntable is located at the lower position in front of the T-shaped frame.

[0011] Optionally, the upper front position of the collection rack is a sloping slideway. The collection rack is located directly above the collection box. An arc-shaped screening mesh is fixedly connected to the lower position inside the collection rack, and the splitting roller is located in the middle position inside the screening mesh.

[0012] Optionally, a driven roller is rotatably connected to the upper position inside the collection rack. The driven roller is provided with four gap grooves. Four cross-shaped crushing rods of the splitting roller are located in the four gap grooves of the driven roller. A gear A is fixedly connected to the right side position of the driven roller. The gear A meshes with the gear B, and the diameter of the gear A is twice the diameter of the gear B.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The collection bin collects and temporarily stores the waste of automotive interior and exterior plastic products of appropriate size crushed by the splitting roller and the driven roller. Within a short period after the production of the waste of automotive interior and exterior plastic products, the recycling process of the waste of automotive interior and exterior plastic products can be completed, avoiding the situation where the properties of the waste of automotive interior and exterior plastic products become stable after cooling and are difficult to crush subsequently, and at the same time avoiding the accumulation of the waste of automotive interior and exterior plastic products after production.

[0014] In addition, by starting the airtight detection component to detect the airtightness of the plastic products produced, if the plastic products prepared between the feeding die and the auxiliary die are unqualified when detected by the airtight detection component, when the plastic products fall off the middle position between the feeding die and the auxiliary die and land on the upper end of conveyor belt A, the airtight detection component transmits the information to cylinder B, causing cylinder B to extend and drive the push plate to move backward, thereby pushing the waste of automotive interior and exterior plastic products on the upper end of conveyor belt A to the front end position at the top of conveyor belt B. Through the transportation of conveyor belt B, the waste of automotive interior and exterior plastic products on the upper end of conveyor belt B is conveyed to the rear end position at the top of conveyor belt B, causing the material to fall into the chute above the front end of the collection rack, completing the waste recycling step.

[0015] In addition, start the servo motor and the drive motor respectively. When the servo motor operates, it drives the turntable to rotate. Through the cooperation of the turntable plug and the strip-shaped groove of the transmission part, and the rotational connection between the transmission part and the support rod of the T-shaped frame, the transmission part swings reciprocally in the left-right direction at the front end of the T-shaped frame. Through the meshing transmission between the sector gear at the top of the transmission part and the rack below the reciprocating frame, the reciprocating frame slides reciprocally at the front end of the T-shaped frame, and then drives the collection rack to move reciprocally in the left-right horizontal direction through the reciprocating frame.

[0016] In addition, when the drive motor operates, it will drive the splitting roller to rotate. When the splitting roller rotates, it drives the driven roller to rotate through the meshing of gear A and gear B. At this time, the driven roller and the splitting roller rotate in the opposite direction, crushing the waste of automotive interior and exterior plastic products entering the interior of the collection rack. Combining that the diameter of gear A is twice the diameter of gear B, the rotational speed of the driven roller is less than that of the splitting roller, thereby increasing the friction between the splitting roller and the driven roller on the waste of automotive interior and exterior plastic products and improving the crushing efficiency.

[0017] In addition, after the driven roller and the splitting roller crush the waste of automotive interior and exterior plastic products, the waste between the driven roller and the splitting roller will be transferred to the upper end position inside the screening mesh through the cross-shaped crushing rods of the driven roller. The fragmented waste that meets the spacing of the screening mesh will fall into the collection box through the gaps of the screening mesh, and the fragmented waste that does not meet the spacing of the screening mesh will be secondarily pulled to the position between the driven roller and the splitting roller by the continuous rotation of the driven roller for secondary crushing treatment. At the same time, the reciprocating movement of the collection rack driven by the reciprocating frame in the left and right directions has a lateral oscillation effect on the collection rack, improving the efficiency of the fragmented waste that meets the crushing requirements of the screening mesh passing through the gaps of the screening mesh.

Through the cooperation of the plug rod of the turntable 404 and the strip-shaped groove of the transmission member 405, and the rotational connection between the transmission member 405 and the support rod of the T-shaped frame 401, the transmission member 405 swings back and forth in the left and right directions at the front end of the T-shaped frame 401. Through the meshing transmission between the sector gear at the top of the transmission member 405 and the rack below the reciprocating frame 402, the reciprocating frame 402 reciprocally slides at the front end of the T-shaped frame 401, and then drives the collection frame 5 to move back and forth in the left and right horizontal directions through the reciprocating frame 402.

[0026] Among them, the upper front position of the collection frame 5 is a sloping slideway. The collection frame 5 is located directly above the collection box 301.

[0028] During use: First, assemble the device relatively according to the assembly steps mentioned in the embodiments. After the device is assembled, place the preparation base 1 in a suitable area for use. When using the device, first put the granular raw materials into the feed inlet of the feed mold 104 to provide an appropriate amount of raw materials for plastic product molding for the feed mold 104. Start the cylinder A102, and the cylinder A102 drives the conveying plate 103 to slide forward in the sliding member 101, so that the front end of the feed mold 104 fits with the rear end of the auxiliary mold 201 to produce plastic products. After the plastic products are prepared at the middle position between the feed mold 104 and the auxiliary mold 201, start the airtightness detection member 2 to detect the airtightness of the produced plastic products. If the plastic products prepared between the feed mold 104 and the auxiliary mold 201 are unqualified detected by the airtightness detection member 2, when the plastic products fall off the middle position between the feed mold 104 and the auxiliary mold 201 and land on the upper end of the conveyor belt A105, the airtightness detection member 2 transmits the command information to the cylinder B202, causing the cylinder B202 to extend and drive the push plate 203 to move backward, so as to push the waste of the automotive interior and exterior plastic products on the upper end of the conveyor belt A105 to the front end position at the top of the conveyor belt B106. Through the transportation of the conveyor belt B106, the waste of the automotive interior and exterior plastic products on the upper end of the conveyor belt B106 is transported to the rear end position at the top of the conveyor belt B106, so that the material falls into the chute above the front end of the collection rack 5 to complete the waste recycling step; At the same time, start the servo motor 403 and the drive motor 501 respectively. When the servo motor 403 operates, it drives the turntable 404 to rotate. Through the cooperation of the insertion rod of the turntable 404 and the strip groove of the transmission member 405, and the rotational connection between the transmission member 405 and the support rod of the T-shaped frame 401, the transmission member 405 swings back and forth in the left and right directions at the front end of the T-shaped frame 401. Through the meshing transmission between the sector gear at the top of the transmission member 405 and the rack below the reciprocating frame 402, the reciprocating frame 402 slides back and forth at the front end of the T-shaped frame 401, and then drives the collection rack 5 to move back and forth horizontally left and right; When the drive motor 501 operates, it will drive the splitting roller 503 to rotate. When the splitting roller 503 rotates, it drives the driven roller 504 to rotate through the meshing cooperation of the gear A505 and the gear B506. At this time, the driven roller 504 and the splitting roller 503 rotate in the reverse direction, and the waste of the automotive interior and exterior plastic products entering the collection rack 5 is crushed. Considering that the diameter of the gear A505 is twice the diameter of the gear B506, the rotation speed of the driven roller 504 is less than the rotation speed of the splitting roller 503, thereby increasing the friction between the splitting roller 503 and the driven roller 504 on the waste of the automotive interior and exterior plastic products and improving the crushing efficiency.

[0029] After the driven roller 504 and the splitting roller 503 crush the waste of automotive interior and exterior plastic products, the waste between the driven roller 504 and the splitting roller 503 will be transferred to the upper end position inside the screening mesh 502 through the cross-shaped crushing rods of the driven roller 504. The fragmented waste that meets the spacing of the screening mesh 502 will fall into the collection box 301 through the gaps of the screening mesh 502, and the fragmented waste that does not meet the spacing of the screening mesh 502 will be secondarily pulled by the continuous rotation of the driven roller 504 to the position between the driven roller 504 and the splitting roller 503 for secondary crushing treatment. At the same time, the reciprocating frame 402 drives the reciprocating movement of the collection frame 5 in the left and right directions to produce a lateral oscillation effect on the collection frame 5, improving the efficiency of the fragmented waste that meets the crushing requirements of the screening mesh 502 passing through the gaps of the screening mesh 502.
