[0002] Plastic crusher is mainly used to crush various plastics and rubbers such as plastic profiles, tubes, rods, wires, films, and waste rubber products. The pellets can be directly used for extruders or injection molding, or they can be recycled through basic granulation. Another type of plastic crusher is a peripheral device for injection molding machines, which can crush and recycle defective products and sprue materials produced by injection molding machines; the main structure of the plastic crusher includes two relatively set crushing rollers and a discharge pipe structure. The discharge pipe structure is generally located below the crushing rollers. The plastic products are placed between the two crushing rollers, crushed by the crushing rollers, and then fall into the discharge pipe and then flow out of the discharge pipe.

[0003] However, most of the existing discharge pipes are stainless steel sheet metal structures. When block or granular plastics fall and hit the inner wall of the discharge pipe, they will make a loud noise and have a certain impact on the inner wall, causing the discharge pipe to loosen. The noise will also pollute the on-site working environment.

[0004] In view of the above problems, the present utility model is proposed. Utility Model Content

[0013] Preferably, the downward projection of the edge of the first buffer plate away from the upper cylinder falls on the second buffer plate.

[0014] Preferably, a downward projection of the edge of the second buffer plate away from the upper cylinder falls on the buffer bottom plate.

[0015] Preferably, the guide plate group includes a first guide plate, a second guide plate and a third guide plate, the first guide plate is vertically arranged in the middle position of the upper surface of the buffer bottom plate, and the second guide plate and the third guide plate are inclinedly arranged on both sides of the upper surface of the buffer bottom plate.

Multiple buffer columns can prevent the small pieces of products from moving too fast and bouncing. The small pieces of plastic products slide from the first buffer plate to the second buffer plate. The buffer pad can reduce the impact of the small pieces of plastic products on the second buffer plate. Then the small pieces of plastic products enter the lower cylinder.

[0019] Small pieces of plastic products fall on the buffer bottom plate and slide down along the buffer bottom plate. The first guide plate, the second guide plate and the third guide plate can reduce the sliding speed of the small pieces of plastic products. When the small pieces of plastic products jump up and touch the buffer side plates, the buffer side plates can reduce the impact noise of the small pieces of plastic products.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0026] like Figure 1-3 As shown, a shock-absorbing and noise-reducing structure of a plastic crusher comprises an upper cylinder 1 and a lower cylinder 2, wherein the upper surface and the lower surface of the upper cylinder 1 are both open, the lower cylinder 2 is inclined, the upper surface and the inclined lower surface of the lower cylinder 2 are both open, the lower surface of the upper cylinder 1 is connected to the upper surface of the lower cylinder 2, and the interiors of the upper cylinder 1 and the lower cylinder 2 are connected, that is, small pieces of plastic can pass through the upper cylinder 1 and the lower cylinder 2;

[0027] A first buffer plate 11 and a second buffer plate 12 are obliquely arranged in the upper cylinder 1. The first buffer plate 11 is located above the second buffer plate 12. A plurality of buffer columns 111 are arranged on the surface of the first buffer plate 11. A buffer pad 121 is arranged on the surface of the second buffer plate 12. When a small piece of plastic product falls, it is first buffered by the first buffer plate 11 and then by the second buffer plate 12.

[0028] A buffer bottom plate 21 is provided on the inner bottom surface of the lower cylinder 2, and buffer side plates 22 are provided on the two opposite inner side walls of the lower cylinder 2. A plurality of guide plate groups are also provided on the buffer bottom plate 21. Both the buffer bottom plate 21 and the buffer side plates 22 are made of rubber material; the angle between the back plate of the upper cylinder 1 and the back plate of the lower cylinder 2 is 135°.

[0029] The buffer columns 111 are all perpendicular to the first buffer plate 11 . The plurality of buffer columns 111 are evenly distributed at equal intervals along the length direction and the width direction of the first buffer plate 11 . The buffer columns 111 are made of hard rubber.

[0030] The included angle between the first buffer plate 11 and the second buffer plate 12 and the inner wall of the upper cylinder 1 is 45-60 degrees. Both sides of the first buffer plate 11 and the second buffer plate 12 are fixedly mounted on the two inner side walls of the upper cylinder 1 .

[0031] The downward projection of the edge of the first buffer plate 11 away from the upper cylinder 1 falls on the second buffer plate 12 ; the downward projection of the edge of the second buffer plate 12 away from the upper cylinder 1 falls on the buffer bottom plate 21 .

[0032] The guide plate group includes a first guide plate 23, a second guide plate 24 and a third guide plate 25. The first guide plate 23 is vertically arranged in the middle position of the upper surface of the buffer bottom plate 21, and the second guide plate 24 and the third guide plate 25 are inclinedly arranged on both sides of the upper surface of the buffer bottom plate 21.

[0033] The second guide plate 24 and the third guide plate 25 are inclined in opposite directions. The distance between the second guide plate 24 and the first guide plate 23 gradually decreases along the falling direction of the material, and the distance between the third guide plate 25 and the first guide plate 23 gradually increases along the falling direction of the material, which can reduce the vibration and noise generated when small pieces of plastic products slide down.

[0034] In summary: the entire device is installed below the crushing roller of the crusher. When the plastic products are crushed into small pieces, the small pieces of products fall into the upper cylinder 1 and first fall on the first buffer plate 11. The multiple buffer columns 11 can prevent the small pieces of products from moving too fast and also prevent the small pieces from bouncing.

[0035] The small piece of plastic product slides down from the first buffer plate 11 and enters the second buffer plate 12. The buffer pad 121 can reduce the impact of the small piece of plastic product on the second buffer plate 12. Then the small piece of plastic product enters the lower cylinder 2.

[0036] The small piece of plastic product first falls on the buffer bottom plate 21 and slides down along the buffer bottom plate 21. The first guide plate 23, the second guide plate 24 and the third guide plate 25 can cooperate to reduce the sliding speed of the small piece of plastic product. When the small piece of plastic product jumps up and touches the buffer side plate 22, the buffer side plate 22 can reduce the impact noise of the small piece of plastic product.

[0037] The buffer plate and buffer pad can reduce the noise generated by the impact of small pieces of plastic products, and can also buffer the impact force, so that the overall structure of the upper cylinder 1 and the lower cylinder 2 is more stable, and the noise is also smaller when small pieces of plastic products flow through.

[0038] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical solution and the utility model concept of the present invention, which are all covered by the protection scope of the present invention.
