Description

Technical Field

[0001] This utility model relates to the technical field of plastic recycling devices, and in particular to a plastic recycling device for the production of plastic products. Background Technology

[0002] Plastic products are common in our daily lives and have a wide range of applications. During the production of plastic products, waste gas or excess waste and residue are usually generated. In order to save production costs, the above-mentioned plastics are usually recycled and reused.

[0003] A search revealed a public disclosure (announcement) number: CN216658576U, which discloses a plastic recycling device for plastic product manufacturing. The device includes a base plate, on which are arranged a crushing box with openings at the top and bottom, and a vibrating box with an opening at the top. Two cooperating crushing rollers are rotatably mounted inside the crushing box. Fixed blades that cooperate with the crushing rollers are mounted on the inner wall of the crushing box. An inclined transition plate is located at the lower end of the crushing box, with one end extending above the vibrating box. A vibrating motor and a through hole are located on the bottom surface of the vibrating box. Sleeves are provided at the four corners of the bottom surface of the filter box. Supports corresponding to the sleeves are provided on the base plate, and springs are installed between the support columns and the sleeves. A recycling box is located on the base plate below the filter box. The advantages of this invention compared to existing technologies are: it incorporates crushing and filtering functions, which facilitates the later recycling and reuse of plastics.

[0004] Although the above solution has crushing and filtering functions, which helps with the later recycling and reuse of plastics, the impact force when the plastic is thrown into the recycling device is too great, which can easily damage the internal parts of the device. In addition, the cutting efficiency is not high and the cutting effect on plastics is not good enough. Utility Model Content

[0005] The main purpose of this utility model is to provide a plastic recycling device for the production of plastic products. By setting up a feeding unit, it solves the problem that the impact force of plastic when it is thrown into the recycling device is too large, which can easily damage the internal parts of the device. By setting up a cutting unit, it solves the problem that the cutting efficiency is not high and the cutting effect of plastic is not good enough.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A plastic recycling device for the production of plastic products includes a main body, a feeding unit disposed at the top of the main body, and a cutting unit disposed inside the main body.

[0008] The feeding unit includes a limiting frame fixedly connected to one side of the top of the main body, a buffer component disposed inside the limiting frame, and a feeding component disposed at the top of the limiting frame.

[0009] The cutting unit includes a cutting component disposed inside the main body and an auxiliary component disposed at the bottom of the cutting component.

[0010] Preferably, the buffer assembly in the feeding unit includes a limiting block fixedly connected to both sides of the limiting frame, a placement groove opened inside the limiting block, a groove connected to the bottom end of the placement groove, an elastic column disposed inside the placement groove, a spring disposed on the surface of the elastic column, an extension block fixedly connected to the bottom end of the elastic column, and a baffle fixedly connected to one end of the extension block.

[0011] Preferably, the feeding assembly in the feeding unit includes two fixed plates fixedly connected to the top of the limiting frame, a connecting frame fixedly connected between the two fixed plates, multiple fixed shafts fixedly connected inside the connecting frame, and a buffer shaft rotatably disposed on the side of the fixed shaft.

[0012] Preferably, the feeding unit further includes a feeding port opened on one side of the top of the main body, and the feeding port is connected to the limiting frame.

[0013] Preferably, the cutting component in the cutting unit includes a rotating motor fixedly connected to one side of the top of the main body, a rotating shaft fixedly connected to the bottom of the rotating motor, two linkage shafts rotatably disposed inside the top of the main body, a sleeve ring fixedly connected to the top of the side of the linkage shaft, a transmission belt disposed between the two sleeve rings, multiple horizontal plates fixedly connected to the side of the linkage shaft, and cutting blades fixedly connected to both ends of the horizontal plates.

[0014] Preferably, the rotating shaft in the cutting unit cutting assembly is fixedly connected to the top end of one of the sleeve rings, and the length of the horizontal plate increases sequentially from top to bottom.

[0015] Preferably, the cutting component in the cutting unit further includes two vertical plates fixedly connected to the top of the main body, and an inclined plate fixedly connected to the bottom of the vertical plates.

[0016] Preferably, the auxiliary components in the cutting unit include two electric rods rotatably disposed in the middle of the main body, a turntable fixedly connected to the side of the electric rods, a rotating blade fixedly connected to the side of the turntable, two triangular seats fixedly connected to the inner side of the main body, and a collection frame disposed at the bottom of the triangular seats.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] I. In this utility model, by setting up a feeding unit, plastic is dropped between two fixed plates. The plastic will first hit the buffer shaft to reduce some of the impact force, and then move downward under the action of gravity and fall onto the two baffles. Under the action of elastic columns and springs, the bottom end of the baffles continues to move downward. During this process, the impact force of the plastic is completely converted until the plastic falls into the body. The baffles return to their original position under the action of elastic columns and springs. This effectively reduces the impact force of the plastic and effectively protects the internal parts of the device.

[0019] II. In this utility model, by setting up a cutting unit, after the plastic is put in, the rotating motor is started to drive the rotating shaft to rotate. Under the action of the transmission belt, the two linkage shafts rotate together, thereby driving multiple horizontal plates and cutting blades to rotate and cut the plastic. Since the length of the multiple horizontal plates increases sequentially from top to bottom, the cutting efficiency is effectively improved. In addition, the electric rod is started to drive the turntable and rotating blades to rotate, assisting in cutting the plastic fragments again. Finally, the plastic fragments fall into the collection box, thus optimizing the cutting effect of the plastic. Attached Figure Description

[0031] The feeding unit 2 includes a limiting frame 201 fixedly connected to one side of the top of the main body 1, a buffer component disposed inside the limiting frame 201, and a feeding component disposed at the top of the limiting frame 201.
