Description

Technical Field

[0001] This utility model belongs to the field of automotive plastic parts recycling technology, and specifically relates to a crushing device for recycling automotive plastic parts. Background Technology

[0002] Automotive plastic parts recycling refers to the process of collecting, sorting, processing, and reusing waste automotive plastic parts. The purpose of automotive plastic parts recycling is to reduce waste generation, reduce environmental impact, save resources and energy, and achieve sustainable development. The steps of automotive plastic parts recycling include collection, sorting, crushing, and reuse.

[0003] Existing patent: CN202420037764.7 A crushing device for recycling automotive plastic parts. Through the dust suction device on the top, plastic dust is sucked into the dust collection box through the dust suction port, which can effectively collect and treat plastic dust and avoid environmental pollution. The crushed plastic falls into the filter screen in the filter drawer. The filter screen leaves large plastic particles on the screen for secondary crushing. The remaining fine particles fall into the discharge slope and are sent out from the discharge port. After crushing, the filter drawer can be pulled out by the drawer handle to remove the dust accumulated on the filter screen. Finally, the dust removal door can be opened by the door handle to clean the dust inside the dust collection box.

[0004] However, in this comparative example, after the automotive plastic parts are crushed, the filter drawer needs to be pulled out using the drawer handle to remove the dust accumulated on the filter screen. In this comparative example, the filter drawer is located on top of the crushing chamber. Since crushing chambers are generally quite tall, if you want to pull out the filter drawer, you need to climb to the top of the crushing chamber. This makes cleaning the filter drawer very inconvenient and laborious, thus reducing the practicality of the crushing device. Utility Model Content

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model prevents dust from falling through the vertical pipe and connecting pipe to the discharge point below the crushing box during dust discharge, thus enabling the discharge of dust collected in the vertical pipe. This makes the dust discharge operation convenient and eliminates the need to climb to the top of the crushing box for disassembly, saving more effort and increasing the practicality of the crushing equipment for recycling automotive plastic parts.

[0016] 2. This utility model uses a striking block to strike the vertical pipe, which causes the vertical pipe and connecting pipe to vibrate, thus shaking off the dust on the inner wall of the vertical pipe and connecting pipe.

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] Please see Figures 1-6 As shown, this utility model is a crushing device for recycling automotive plastic parts, including a crushing box 1. A feed hopper 3, communicating with the interior of the crushing box 1, is fixedly connected to the upper surface of the crushing box 1. A discharge cylinder 4, communicating with the interior of the crushing box 1, is fixedly connected to the lower surface of the crushing box 1. Support bases 2 are fixedly connected to the outer surfaces of both the left and right sides of the crushing box 1. A crushing mechanism is installed inside the crushing box 1 for crushing automotive plastic parts to facilitate their recycling. A vertical pipe 8 is fixedly connected to the front surface of the crushing box 1. A dust collection mechanism is installed on the vertical pipe 8, communicating with the interior of the feed hopper 3. The dust collection mechanism prevents plastic dust generated during the crushing process from being thrown into the air through the feed hopper 3. A striking mechanism is installed on the front side of the vertical pipe 8. The crushing mechanism can drive the striking mechanism to strike the vertical pipe 8 and the dust collection mechanism, allowing the collected plastic dust to fall smoothly out of the dust collection mechanism.

[0032] During operation, automotive plastic parts enter the crushing chamber 1 through the feed hopper 3. The crushing mechanism is then activated to crush the plastic parts. Next, the dust collection mechanism is activated, drawing the plastic dust generated during crushing into the vertical pipe 8 through the feed hopper 3. This prevents the plastic dust from rising into the air through the feed hopper 3. After crushing stops, the dust collection mechanism stops drawing dust from the feed hopper 3. The dust in the vertical pipe 8 then falls to the discharge point of the crushing chamber 1 under gravity due to the pull-out dust collection mechanism. The activation of the crushing mechanism also activates the striking mechanism, causing it to strike the vertical pipe 8 and vibrate. This prevents dust accumulation inside the vertical pipe 8, allowing the collected plastic dust to fall smoothly out of the dust collection mechanism.

[0033] In one embodiment, the crushing mechanism includes two support shafts 11 rotatably connected between the front and rear inner walls of the crushing box 1. The rear ends of the support shafts 11 rotatably extend through the rear surface of the crushing box 1. Two motors 10 are fixedly connected to the rear surface of the crushing box 1. The rear ends of the support shafts 11 are fixedly connected to the rotation output shaft of the motors 10. The front end of the support shaft 11 on the right rotatably extends through the front surface of the crushing box 1. Crushing rollers 12 are fixedly sleeved on the outer surfaces of the two support shafts 11. The two crushing rollers 12 are located inside the crushing box 1 and are adapted to the interior of the crushing box 1. The two crushing rollers 12 are mutually adapted to each other.

[0034] When the motor 10 is started, it will drive the corresponding support shaft 11 to rotate, which in turn drives the crushing roller 12 to rotate synchronously. The two crushing rollers 12 can crush automotive plastic parts by rotating relative to each other at the same time.

[0035] In one embodiment, the dust collection mechanism includes a connecting pipe 5, which is fixedly connected to the lower surface of the vertical pipe 8. The connecting pipe 5 is inclined and communicates with the interior of the vertical pipe 8. Two through holes communicating with the interior of the feed hopper 3 are opened on the front surface of the feed hopper 3. Two dust collection pipes 6 are fixedly connected to the front surface of the feed hopper 3. The dust collection pipes 6 communicate with the interior of the through holes. A first filter screen 7 is fixedly sleeved in each through hole. A baffle 26 is fixedly connected to the front inner wall of the feed hopper 3. The baffle 26 is inclined.

[0036] The lower end of the dust collection pipe 6 is fixedly connected to the upper surface of the vertical pipe 8. The dust collection pipe 6 communicates with the interior of the vertical pipe 8. The front surface of the vertical pipe 8 is fixedly connected to the corrugated pipe 9, which communicates with the interior of the vertical pipe 8. The rear end of the corrugated pipe 9 is fixedly fitted with a second filter screen 27. The left side surface of the vertical pipe 8 is fixedly connected to a sliding frame 20. The left side surface of the vertical pipe 8 is provided with a sealing groove 22 that communicates with the interior of the vertical pipe 8. A sealing plate 21 is slidably connected in the sealing groove 22.

[0037] The sliding frame 20 is slidably sleeved on the outer surface of the sealing plate 21. The left side surface of the sealing plate 21 extends slidably out of the left side surface of the sliding frame 20. The upper surface of the sealing plate 21 has a handle groove 24 extending out of its lower surface. The upper surface of the sliding frame 20 is threadedly connected to a bolt 25. The lower end of the bolt 25 is threaded through the sliding frame 20. The upper surface of the sealing plate 21 has a fixing hole 23. The lower end of the bolt 25 is slidably connected to the fixing hole 23. A sealing element is provided in the sealing groove 22.

[0038] In this scheme, a vacuum pump is installed at the end of the corrugated pipe 9 away from the vertical pipe 8. The suction end of the vacuum pump is fixedly connected to the corrugated pipe 9, and the vacuum pump is fixedly installed on the outer surface of the crushing box 1.

[0039] In addition, in specific applications, the sealing plate 21 is slid into the sealing groove 22, and then the bolt 25 is rotated so that the lower end of the bolt 25 slides into the fixing hole 23. The lower end of the bolt 25 slides into the fixing hole 23 to fix the sealing plate 21, so that the sealing plate 21 cannot be pulled out from the sealing groove 22. The sealing plate 21 sliding into the sealing groove 22 can seal the lower side of the vertical pipe 8. At this time, the vacuum pump is started, and its suction end sucks into the vertical pipe 8. Because the lower side of the vertical pipe 8 is sealed by the sealing plate 21, the vacuum pump sucks into the upper side of the vertical pipe 8, thereby sucking into the feed hopper 3 through the dust collection pipe 6. When the plastic dust generated during the crushing of automotive plastic parts enters the feed hopper 3 from the crushing box 1, it will be sucked into the dust collection pipe 6 and then into the vertical pipe 8, thereby preventing the plastic dust generated during the crushing of automotive plastic parts from rising into the air through the feed hopper 3, thus achieving the dust reduction effect of the crushing equipment for recycling automotive plastic parts.

[0040] After the dust is sucked into the vertical pipe 8, the vacuum pump is stopped, and then the bolt 25 is rotated so that it slides out of the fixing hole 23. The sealing plate 21 is then pulled to the left out of the vertical pipe 8. At this time, the dust will fall through the vertical pipe 8 and the connecting pipe 5 to the discharge point below the crushing box 1, thus realizing the discharge of the dust collected in the vertical pipe 8. This makes the dust discharge operation convenient and eliminates the need to climb to the top of the crushing box 1 for disassembly, saving more effort and increasing the practicality of the crushing equipment for recycling automotive plastic parts.

[0041] In one embodiment, the striking mechanism includes a second slide bar 19, which is fixedly connected to the front end of the support shaft 11 located on the right side. Two connecting blocks 13 are fixedly connected to the front surface of the vertical tube 8. A fixed rod 14 is rotatably connected between the two connecting blocks 13. The left end of the fixed rod 14 rotatably passes through the left side surface of the connecting block 13 located on the left side. A first slide bar 15 is fixedly sleeved on the outer surface of the fixed rod 14. The first slide bar 15 is inclined. A striking block 18 is fixedly connected to the lower end of the first slide bar 15. The outer surface of the striking block 18 contacts the front surface of the vertical tube 8.

[0042] The outer surface of the second slide bar 19 is slidably connected to the outer surface of the first slide bar 15. A limiting post 16 is fixedly connected to the left surface of the connecting block 13 on the left side. A reset spring 17 is provided on the limiting post 16. The outer end of the reset spring 17 is fixedly connected to the limiting post 16, and the inner end of the reset spring 17 is fixedly connected to the fixing rod 14.

[0043] During the rotation of the support shaft 11, the second slide rod 19 will also rotate. During this rotation, the second slide rod 19 will contact the first slide rod 15 and, during its rotation, will move the first slide rod 15 from top to bottom, causing the first slide rod 15 and the striking block 18 to rotate around the fixed rod 14. This process gradually increases the torque of the return spring 17. As the striking block 18 rotates around the fixed rod 14, it moves away from the front surface of the vertical tube 8. When the second slide rod 19 rotates to the point of disengagement from the first slide rod 15, the release force of the return spring 17... Under the action of the first sliding rod 15 and the striking block 18, the striking block 18 is reset. During the reset process, the striking block 18 contacts and strikes the front surface of the vertical tube 8. Thus, every time the support shaft 11 rotates, it drives the striking block 18 to strike the front surface of the vertical tube 8 once. During the striking of the vertical tube 8 by the striking block 18, the vertical tube 8 and the connecting pipe 5 will vibrate, thereby shaking off the dust on the inner wall of the vertical tube 8 and the connecting pipe 5. This ensures smooth discharge of material from the vertical tube 8 and the connecting pipe 5 and avoids dust adhering to the inner wall of the vertical tube 8 and the connecting pipe 5, thereby increasing the practicality of the crushing equipment for recycling automotive plastic parts.

[0044] In this design, the baffle 26 can protect the first filter screen 7 and prevent the automotive plastic parts from scratching the first filter screen 7 during feeding.

[0045] In this design, the mesh size of the first filter 7 is slightly larger, which is to prevent automotive plastic parts from entering the dust collection pipe 6 during feeding.

[0046] In this design, the second filter screen 27 has smaller mesh size to prevent dust from entering the vacuum pump.

[0047] In summary, by utilizing the above-mentioned technical solution of this utility model, by sliding the sealing plate 21 into the sealing groove 22 and then rotating the bolt 25 so that the lower end of the bolt 25 slides into the fixing hole 23, the sealing plate 21 is fixed, preventing it from being pulled out of the sealing groove 22. The sliding of the sealing plate 21 into the sealing groove 22 seals the lower side of the vertical pipe 8. At this time, the vacuum pump is started, and its suction end suctions the vertical pipe 8. Because the lower side of the vertical pipe 8 is sealed by the sealing plate 21, the vacuum pump will draw from the upper side of the vertical pipe 8, thereby drawing from the feed hopper 3 through the dust collection pipe 6. When the plastic dust generated during the crushing of automotive plastic parts enters the feed hopper 3 from the crushing box 1, it will be drawn into the dust collection pipe 6 and then into the vertical pipe 8. This prevents the plastic dust generated during the crushing of automotive plastic parts from rising into the air through the feed hopper 3, thus achieving the dust reduction effect of the crushing equipment for recycling automotive plastic parts.

[0048] After the dust is sucked into the vertical pipe 8, the vacuum pump is stopped, and then the bolt 25 is rotated so that it slides out of the fixing hole 23. The sealing plate 21 is then pulled to the left out of the vertical pipe 8. At this time, the dust will fall through the vertical pipe 8 and the connecting pipe 5 to the discharge point below the crushing box 1, thus realizing the discharge of the dust collected in the vertical pipe 8. This makes the dust discharge operation convenient and eliminates the need to climb to the top of the crushing box 1 for disassembly, saving effort and increasing the practicality of the crushing equipment for recycling automotive plastic parts. When the motor 10 is started, it will drive the corresponding support shaft 11 to rotate, which in turn drives the crushing roller 12 to rotate. The two crushing rollers 12 rotate relative to each other at the same time to crush automotive plastic parts. During the rotation of the support shaft 11, the second slide rod 1 will also be driven. As the second slide rod 19 rotates, it contacts the first slide rod 15 during rotation. The second slide rod 19 also moves the first slide rod 15 from top to bottom, causing the first slide rod 15 and the striking block 18 to rotate around the fixed rod 14. During this process, the torque of the reset spring 17 gradually increases. As the striking block 18 rotates around the fixed rod 14, it moves away from the front surface of the vertical tube 8. When the second slide rod 19 rotates to contact the first slide rod 15... When the slide bar 15 disengages, the release force of the reset spring 17 drives the first slide bar 15 and the striking block 18 to reset. During the reset process, the striking block 18 contacts and strikes the front surface of the vertical tube 8. Thus, every time the support shaft 11 rotates, it drives the striking block 18 to strike the front surface of the vertical tube 8 once. During the striking process of the striking block 18, the vertical tube 8 and the connecting pipe 5 will vibrate, thereby shaking off the dust from the inner wall of the vertical tube 8 and the connecting pipe 5.

[0049] Through the above technical solution, 1. When the dust is discharged, it will not fall through the vertical pipe 8 and the connecting pipe 5 to the discharge point below the crushing box 1, thereby realizing the discharge of the dust collected in the vertical pipe 8. This makes the dust discharge operation convenient and eliminates the need to climb to the top of the crushing box 1 for disassembly, saving more effort and increasing the practicality of the crushing equipment for recycling automotive plastic parts.

[0050] 2. During the process of striking the vertical pipe 8 by the striking block 18, the vertical pipe 8 and the connecting pipe 5 will vibrate, which will shake off the dust on the inner wall of the vertical pipe 8 and the connecting pipe 5, thereby ensuring smooth material discharge from the vertical pipe 8 and the connecting pipe 5 and preventing dust from adhering to the inner wall of the vertical pipe 8 and the connecting pipe 5, thus increasing the practicality of the crushing equipment for recycling automotive plastic parts.

[0051] 3. When the plastic dust generated during the crushing of automotive plastic parts enters the feed hopper 3 from the crushing box 1, it will be sucked into the dust collection pipe 6 and then into the vertical pipe 8. This prevents the plastic dust generated during the crushing of automotive plastic parts from rising into the air through the feed hopper 3, thereby achieving the dust reduction effect of the crushing equipment for recycling automotive plastic parts.

[0052] 4. The baffle 26 can protect the first filter screen 7 and prevent the automotive plastic parts from scratching the first filter screen 7 during feeding.
