[0036] When a car is scrapped and recycled, due to the various shapes and large sizes of automotive injection molded parts, they often cannot be directly recycled. The waste automotive injection molded parts need to be pulverized before they can be recycled. Usually, a pulverizing device is used to pulverize the injection molded parts. However, the existing pulverizing devices will generate a large amount of plastic dust during the pulverizing process, which floats in the equipment and even overflows from the feed inlet, resulting in environmental pollution. Inhaling it by workers can seriously lead to respiratory diseases, and it is extremely inconvenient to use.

[0037] Therefore, the present utility model proposes a waste automotive injection molded part pulverizing and recycling device, which can effectively improve the above problems.

[0038] Refer to Figures 1 to 4 As shown, a waste automotive injection molded part pulverizing and recycling device according to an embodiment of the present utility model includes: a pulverizing box 100, a pulverizing mechanism 200, a receiving box 300, and a dust suction mechanism 400.

The peripheral wall of the crushing roller is provided with crushing teeth. The two crushing rollers are arranged in parallel at intervals, and the two crushing rollers are connected with a power device. The power device is used to drive the two crushing rollers to rotate in opposite directions. The power device can adopt various structural forms, which is a conventional technical means in the prior art. The present utility model does not make improvements thereto, so no specific description will be made herein.

[0042] The dust suction mechanism 400 includes a dust suction pipe 410 and a vacuum cleaner (not shown in the figure). The dust suction pipe 410 is detachably connected to the dust outlet pipe 120. The dust suction mechanism 400 is used to suck the dust in the crushing chamber 101. That is, the vacuum cleaner sucks the dust in the crushing chamber 101 through the dust suction pipe 410. A sieve plate 130 for screening dust is detachably provided between the dust suction pipe 410 and the dust outlet pipe 120. It can be understood that the sieve plate 130 can allow fine plastic dust to pass through while blocking large-sized plastics, avoiding a large amount of crushed plastics being sucked away by the dust suction mechanism 400, and at the same time avoiding large-sized plastics entering the dust suction mechanism 400 and causing damage to it. In addition, the sieve plate 130 is detachably arranged, which can facilitate its disassembly and cleaning. The dust suction pipe 410 is detachably connected to the dust outlet pipe 120, which can facilitate the disassembly of the dust suction pipe 410 to clean and dredge its interior.

[0043] During use, the waste of automotive injection molded parts is put into the crushing chamber 101 from the feed hopper 110. The crushing mechanism 200 and the dust suction mechanism 400 are started. The waste of automotive injection molded parts is crushed by the crushing mechanism 200. The crushed plastic falls into the material receiving box 300, and some fine plastic dust floating in the crushing chamber 101 during the crushing process is sucked away by the dust suction mechanism 400, so as to effectively collect and process the floating plastic dust, reduce environmental pollution and harm to the human body.

[0044] For the waste crushing and recycling device of automotive injection molded parts according to an embodiment of the present utility model, by providing the dust suction mechanism 400, it can effectively remove some fine plastic dust floating in the crushing chamber 101 during the crushing process, reduce environmental pollution and harm to the human body. By providing the detachable sieve plate 130, it can block large-sized plastics, avoid a large amount of crushed plastics being sucked away by the dust suction mechanism 400, and at the same time avoid large-sized plastics entering the dust suction mechanism 400 and causing damage to it.

The side away from the first connecting flange 122, thereby pressing the second connecting flange 412 to the first connecting flange 122, and the tightening and loosening operations can be achieved by screwing the locking screw 520, wherein the rotating part 510 can be rotated to avoid the axial moving path of the second connecting flange 412 along the dust suction pipe 410, that is, the lock of the second connecting flange 412 is released, so that the dust suction pipe 410 can move away from the dust outlet pipe 120 along its axial direction until it is separated from the dust outlet pipe 120. By setting the above structure, the disassembly and assembly of the dust suction pipe 410 can be facilitated.
