Description

Technical Field

[0001] This utility model belongs to the field of TPU recycling technology, specifically relating to a TPU film recycling and crushing device. Background Technology

[0002] TPU possesses excellent high tensile strength, high tear strength, toughness, and aging resistance, making it a mature and environmentally friendly material. Currently, TPU is widely used in medical and health, electronics, industry, and sports. It has unparalleled strength, toughness, wear resistance, cold resistance, oil resistance, water resistance, aging resistance, and weather resistance compared to other plastic materials. At the same time, it has many excellent functions such as high waterproofness and breathability, windproofness, cold protection, antibacterial properties, mildew resistance, warmth retention, UV resistance, and energy release. TPU material processing generates waste, which can be recycled and reused. However, existing recycling devices have simple structures and cannot crush TPU, thus failing to meet production needs. Summary of the Invention

[0003] The present invention aims to solve the technical problems existing in the prior art and provide a TPU film recycling and crushing device.

[0004] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: A TPU film recycling and crushing device includes two connecting plates. Two power rollers are provided between the rear ends of the two connecting plates. The two power rollers are aligned vertically and both ends are rotatably connected to the two connecting plates. A shear plate is mounted in the middle of the two connecting plates. A cutting roller is provided on the front side of the shear plate. The left and right ends of the cutting roller are rotatably connected to the connecting plates on both sides. The surface of the cutting roller includes multiple slicing blades and multiple cutting blades. The cutting blades are arranged laterally along the axis of the cutting roller and arranged in a circular array along the axis of the cutting roller. Multiple slicing blades are arranged side by side at intervals on the surface of the cutting roller and arranged in a group in a circular array along the axis of the cutting roller. The front end of the shear plate is provided with a cutting groove for cooperating with the slicing blades. A pulley is provided on the right side of the cutting roller and the right side of one of the power rollers, and a transmission belt is connected between the two pulleys.

[0005] Preferably, the connecting plate on the left side is provided with a motor for driving the cutting roller to rotate.

[0006] Preferably, each of the two power rollers has a gear at its left end, and the two gears mesh with each other.

[0007] The beneficial effects of this utility model are as follows: The cutting assembly uses the cutting blade and strip cutting blade on the cutting roller to cut and crush the TUP film, which facilitates its rapid remelting and reuse after recycling; By setting the strip cutting blade and the cutting blade on the surface of the cutting roller, the strip cutting blade can cut the recycled protective film and TUP film into thin strips, and then the thin strips are crushed by the cooperation of the cutting blade and the shear plate. The crushed film particles can be directly recycled, which is convenient for production needs. Attached Figure Description

[0010] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0011] Example: A TPU film recycling and shredding device, such as Figure 1 As shown, the device includes two connecting plates 3. Two power rollers 4 are positioned between the rear ends of the two connecting plates 3, aligned vertically and rotatably connected at both ends to the two connecting plates 3. A shear plate 5 is mounted in the middle of the two connecting plates 3. A cutting roller 6 is located on the front side of the shear plate 5, with its left and right ends rotatably connected to the connecting plates 3 on both sides. The surface of the cutting roller 6 includes multiple slicing blades 7 and multiple cutting blades 8. The cutting blades 8 are arranged laterally along the axis of the cutting roller 6 and arranged in a circular array along the axis of the cutting roller 6. Multiple slicing blades 7 are arranged side-by-side at intervals on the surface of the cutting roller 6 and arranged in a circular array along the axis of the cutting roller 6. The front end of the shear plate 5 has a cutting groove 9 for engaging the slicing blades 7. A pulley 10 is located on the right side of the cutting roller 6 and on the right side of one of the power rollers 4, and a transmission belt 11 connects the two pulleys 10.

[0012] The connecting plate 3 on the left is provided with a motor 12 for driving the cutting roller 6 to rotate; the left end of each of the two power rollers 4 is provided with a gear 13, and the two gears 13 mesh with each other.

[0013] The principle of this invention is as follows: First, the mold body is separated manually in advance, and the TPU film of the middle layer is sandwiched in the cutting assembly in the middle position. The rotation of the motor 12 drives the cutting roller 6 in the cutting assembly to rotate. At the same time, the cutting roller 6 drives the power roller 4 to rotate through the transmission belt 11, so as to feed the film forward. The cutting blade 7 on the cutting roller 6 is first set with a cutting blade 8 on the surface of the cutting roller 6. The cutting blade 7 can cut the recycled protective film and TUP film into thin strips. Then, the cutting blade 8 and the shear plate 5 cooperate to crush the thin strips. The crushed film particles can be directly recycled.

[0014] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
