Description

Technical Field

[0001] This invention provides a TPU fiber cooling and molding device for preventing adhesion, belonging to the field of polymer material processing technology. Background Technology

[0002] TPU (thermoplastic polyurethane) is a polymer material that can be shaped by heat. The raw materials are mainly in granular and powder form, and it is widely used in extrusion, injection molding, inks, films, and cable sheathing. After melt spinning, thermoplastic polyurethane (TPU) fibers typically require cooling and shaping.

[0003] Existing TPU fiber cooling molding methods typically involve cooling rollers. However, this often results in the TPU fibers sticking to the rollers due to incomplete curing of the fiber surface. Relying solely on the cooling rollers limits the cooling contact area and can lead to uneven cooling on both sides of the fibers, resulting in relatively low cooling efficiency. Therefore, this invention provides an anti-sticking TPU fiber cooling molding device. Utility Model Content

[0004] The technical problem solved by this invention is that the TPU fiber surface is not completely cured and sticks to the cooling roller. Relying solely on the cooling roller to cool the TPU fiber is relatively inefficient and the cooling is not uniform.

[0005] To solve the technical problem, the technical solution provided by this utility model is as follows: a TPU fiber cooling and molding device for preventing adhesion, comprising a base plate, a cooling roller assembly and an air supply cooling assembly on the top of the base plate, the cooling roller assembly comprising two sets of upright plates symmetrically fixed on both sides of the top of the base plate, a pair of cooling rollers rotatably connected between the upright plates in the same set, the surface of the cooling rollers being provided with spiral microgrooves, and a top plate being provided between the tops of the upright plates; the air supply cooling assembly comprising an air spray pipe assembly fixedly disposed on the top of the base plate and the bottom of the top plate, wherein a fan for supplying air to the air spray pipe assembly is provided on the side wall of one of the upright plates.

[0006] Furthermore, the air spray pipe assembly includes several vertical air pipes placed outside the cooling roller, and horizontal air pipes are connected between the ends of the vertical air pipes on the same side. Several air spray heads with the air spray direction facing between the bottom plate and the vertical plate are provided on the vertical air pipes.

[0007] Furthermore, the air outlet of the fan is provided with an air supply pipe that is connected to the cross air duct.

[0008] Furthermore, the cooling roller is made of titanium alloy.

[0009] Furthermore, the surface of the cooling roller is coated with a polytetrafluoroethylene coating with a thickness of 20-50 μm.

[0010] Furthermore, the spiral microgroove has an opening depth of 0.1-0.3 mm and a pitch of 2-5 mm.

[0011] The beneficial effects of this utility model are:

[0012] Through the combined action of the cooling roller assembly and the air supply cooling assembly, the TPU fibers are cooled and molded by contact with the cooling roller made of titanium alloy material. The air supply cooling assembly enables air cooling of the cooling roller and TPU fibers, effectively improving the cooling and molding efficiency of TPU fibers and making the cooling of both sides of the TPU fibers more uniform. The polytetrafluoroethylene coating sprayed on the surface of the cooling roller and the spiral microgrooves opened on the surface have excellent anti-stick properties, which can reduce the fiber contact area and effectively prevent TPU fibers from sticking to the roller surface of the cooling roller.

[0018] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly mentioned in this specification are defined relative to their structure and are relative concepts. Therefore, they may vary depending on their location and usage; thus, these or other directional terms should not be interpreted as restrictive terms.

[0019] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0020] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] According to the appendix Figure 1 , 2 As shown in Figure 4: This utility model provides a TPU fiber cooling and molding device for preventing adhesion: it includes a base plate 1, a cooling roller assembly 2 and an air supply cooling assembly 3 on the top of the base plate 1. The cooling roller assembly 2 includes two sets of upright plates 4 symmetrically fixed on both sides of the top of the base plate 1. A pair of cooling rollers 5 are rotatably connected between the same set of upright plates 4. A top plate 7 is provided between the tops of the upright plates 4. Specifically, the mating gap of the pair of cooling rollers 5 is slightly larger than the thickness of the TPU fiber, about 0.2-0.8 mm, depending on the situation. Thus, when the TPU fiber passes through and moves between the cooling rollers 5, the two can make good contact to achieve cooling and molding of the TPU fiber.

[0022] As per the instruction manual Figure 1 As shown: Cooling roller 5 is made of titanium alloy. Titanium alloy has high corrosion resistance and can operate stably for a long time in humid or corrosive environments, avoiding quality problems caused by condensation or oxidation. At the same time, the good thermal conductivity of titanium alloy can ensure uniform roller surface temperature and prevent local overheating or undercooling. The surface of cooling roller 5 is coated with polytetrafluoroethylene with a thickness of 20-50μm, which has excellent anti-sticking properties. Spiral microgrooves 6 are opened on the surface of cooling roller 5. The depth of spiral microgrooves 6 is 0.1-0.3mm and the pitch is 2-5mm, which reduces the fiber contact area and effectively prevents TPU fibers from sticking to the roller surface of cooling roller 5.

[0023] As per the instruction manual Figure 1-4 As shown: The air supply cooling assembly 3 includes an air duct assembly 8 fixedly installed on the top of the base plate 1 and the bottom of the top plate 7. A fan 9 for supplying air to the air duct assembly 8 is provided on the side wall of one of the vertical plates 4. The air duct assembly 8 includes several vertical air ducts 10 placed outside the cooling rollers 5. A horizontal air duct 11 is provided between the ends of the vertical air ducts 10 on the same side. Several air nozzles 12 with the air spray direction facing between the base plate 1 and the vertical plate 4 are provided on the vertical air ducts 10. The air outlet of the fan 9 is provided with an air supply pipe 13 connected to the horizontal air duct 11. The air duct assembly 8 is fixedly installed on the top of the base plate 1 and the bottom of the top plate 7 by clamps equipped with screws. Specifically, when the fan 9 is started, the air generated by the fan 9 is transported through the air supply pipe 13 to the horizontal air duct 11 and the vertical air duct 10, and sprayed onto the cooling rollers 5 and the TPU fibers between the cooling rollers 5 through several air nozzles 12.

[0024] The principle of this utility model

[0025] During use, the TPU fibers move through the cooling rollers 5 made of titanium alloy, allowing for good contact between the two materials. This enables the TPU fibers to be cooled and molded. Combined with the air supply cooling component 3, the air generated by the fan 9 is sprayed onto the cooling rollers 5 and TPU fibers through several air nozzles 12, achieving air cooling of the cooling rollers 5 and TPU fibers. This effectively improves the cooling and molding efficiency of the TPU fibers and makes the cooling of both sides of the TPU fibers more uniform. The polytetrafluoroethylene coating sprayed on the surface of the cooling rollers 5 and the spiral microgrooves 6 on the surface provide excellent anti-sticking properties, reducing the fiber contact area and effectively preventing the TPU fibers from sticking to the roller surface of the cooling rollers 5.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
