[0025] The utility model will be further illustrated below in combination with the drawings and specific embodiments, and it should be understood that the following specific embodiments are only used to illustrate the utility model and not used to limit the scope of the utility model.
[0026] Please refer to Figures 1-6 A high-density polyethylene recycling device, comprising a top seat 1. Two clamping plates 2 are rotatably installed at the top opening of the top seat 1, and the two clamping plates 2 are mirror image arranged. Each clamping plate 2 extends three chamfered edges 201 at the edge of the extrusion surface, and the bottom edge of the extrusion surface is not provided with chamfered edges 201. When the two clamping plates 2 are closed together, the chamfered edges 201 of the clamping plate 2 cut off part of the broken pieces from the large high-density polyethylene products, and the two clamping plates 2 crush the broken pieces. Each clamping plate 2 is slidably installed with a push frame 3, and the sliding direction of the push frame 3 is perpendicular to the extrusion surface of the clamping plate 2. Each clamping plate 2 is fixedly connected with a telescopic rod 4, and the free end of the telescopic rod 4 is fixedly connected to the middle of the push frame 3. The telescopic rod 4 can be electric or hydraulic. The push foot of each push frame 3 is slidably embedded on one side of the extrusion surface of the clamping plate 2, and the extrusion surface of the push foot of the push frame 3 is flush with the extrusion surface of the clamping plate 2. After the high-density polyethylene product broken pieces are crushed, the two clamping plates 2 are opened, and at the same time the telescopic rod 4 is retracted to push the push frame 3 to push the polyethylene broken pieces away from the clamping plate 2 through the push foot.
[0027] The first gear 5 is coaxially fixedly connected to the rotating shaft of each clamping plate 2, and the two first gears 5 are meshed with each other. One of the first gears 5 is separately meshed with a second gear 6, and the second gear 6 is coaxially connected with a first drive motor 8. The diameter of the first gear 5 is larger than that of the second gear 6, which is used to increase the torque of the first gear 5, so as to increase the force of the two clamping plates 2 extruding the high-density polyethylene products. The outer side wall of the connecting cylinder 9 is fixedly connected with a first mounting frame 7, and the first drive motor 8 is fixedly connected with the first mounting frame 7. The first drive motor 8 drives the second gear 6 to rotate, so that the second gear 6 drives the first gear 5 meshed therewith to rotate, and the two first gears 5 meshed with each other rotate in opposite directions.
[0028] The bottom of the top base 1 is communicated with a crushing mechanism. The crushing mechanism comprises a connecting cylinder 9 communicated with the top base 1. The top base 1 and the connecting cylinder 9 are connected by welding. Two crushing rollers 10 are rotationally connected in the inner cavity of the connecting cylinder 9, and the crushing teeth of the two crushing rollers 10 are engaged with each other. One third gear 12 is coaxially fixedly connected to each crushing roller 10, and one second driving motor 13 is coaxially fixedly connected to one crushing roller 10. A second mounting frame 14 is fixedly connected to the outer side wall of the connecting cylinder 9, and the second driving motor 13 is fixedly connected with the second mounting frame 14. Bearings 11 are sleeved on the both ends of the rotating shaft of each crushing roller 10, and each bearing 11 is embedded in the side wall of the connecting cylinder 9. A connecting ring 15 with multiple through holes is extended outside the opening at the bottom of the connecting cylinder 9, and is used for fixedly connecting the connecting cylinder 9 to the high-density polyethylene collecting device.
[0029] Working principle:
[0030] When the two clamping plates 2 are opened, the part of the high-density polyethylene product to be recycled is placed between the two clamping plates 2, and the lowest part of the high-density polyethylene product extends into the part, which is higher than all the chamfered edges 201. Then the first driving motor 8 drives the second gear 6 to rotate, so that the second gear 6 drives the first gear 5 engaged with it to rotate, and the two first gears 5 engaged with each other drive the two clamping plates 2 to close in opposite directions, so as to flatten the part of the high-density polyethylene product, and at the same time, the three chamfered edges 201 cut off the flattened part of the high-density polyethylene product from the whole. Then the first driving motor 8 is reversed, the two clamping plates 2 are opened, and the flattened high-density polyethylene product falls into the crushing mechanism for crushing;
[0031] When the two clamping plates 2 are opened, the telescopic rod 4 is retracted, so that the push frame 3 pushes the polyethylene sheet clamped between the three chamfered edges 201 away from the clamping plate 2 through the push foot, facilitating the falling of the flattened high-density polyethylene product;
[0032] When the flattened high-density polyethylene product falls between the two crushing rollers 10 with the crushing teeth engaged with each other, the two crushing rollers 10 extrude and crush the flattened high-density polyethylene product downward under the drive of the first driving motor 8, because the two third gears 12 are engaged with each other.
[0033] It should be noted that the above content only illustrates the technical idea of the present application, and cannot limit the protection scope of the present application. For ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements fall within the protection scope of the claims of the present application.
