Description

Technical Field

[0001] This utility model relates to the technical field of fabric cooling equipment, specifically to a cooling device for weaving. Background Technology

[0002] Before leaving the factory, fabrics undergo a series of high-temperature treatments, such as fabric setting, dyeing, and drying after printing. After these high-temperature treatments, the fabric remains at a very high temperature. Without a cooling step, the fabric's properties will be significantly affected. For example, in the setting process, without cooling, the fabric will remain soft and easily deformed. Similarly, in the dyeing and printing processes, without cooling, the heat on the fabric will cause dye molecules to become active again, migrating from the fibers and causing color bleeding. Therefore, a cooling zone is installed at the end of the fabric production line to quickly cool the high-temperature fabric to room temperature, thereby fixing the color, preventing auxiliary agent migration, avoiding wrinkles, and ensuring a smooth fabric surface.

[0003] In existing technologies, fabric cooling devices generally use cooling rollers to rotate the fabric. While moving the fabric forward, the cooling water in the cooling rollers exchanges heat with the fabric to cool it down. However, in order to ensure strength, the cooling rollers are mostly made of stainless steel. As the cooling water flows along the inside of the cooling roller, it enters from one end and flows out from the opposite end. At the same time, due to the long axial length of the cooling roller, there is a high temperature difference between the two ends of the cooling roller, resulting in uneven cooling of the fabric. Summary of the Invention

[0004] In view of the defects existing in the prior art, the purpose of this utility model is to provide a cooling device for weaving, so as to improve the phenomenon of temperature difference at both ends of the cooling roller in the existing fabric cooling device.

The end cap is fixedly installed above the frame. The multiple cooling rollers are evenly spaced and rotated at the upper end of the frame along the fabric conveying direction, and are arranged in a wave-like pattern. An inlet and an outlet for fabric input and output are formed between the frame and the end cap, and the inlet and outlet are arranged opposite to each other. Each cooling roller includes a cooling roller body, a hollow threaded tube disposed in the inner cavity of the cooling roller body, and an outer support layer disposed on the outer surface of the cooling roller body. The hollow threaded tube is arranged along the... The cooling roller body is axially arranged in the inner cavity of the cooling roller body.

[0011] Furthermore, the outer surface of the outer support layer is provided with a copper layer and a nickel layer, which are arranged sequentially from the inside to the outside.

[0012] The beneficial effects of this utility model are as follows: the cooling roller combined with the fabric adopts a hollow threaded tube, a cooling roller body and an outer support layer arranged from the inside to the outside. The hollow threaded tube and the cooling roller body are made of materials with a higher thermal conductivity than the outer support layer.

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] See Figures 1 to 3 As shown, this embodiment provides a cooling device 100 for weaving, including a frame 10, an end cap 20, and a plurality of cooling rollers 40. The end cap 20 is fixedly installed above the frame 10. The plurality of cooling rollers 40 are evenly spaced and rotated at the upper end of the frame 10 along the fabric conveying direction. The plurality of cooling rollers 40 are arranged in a wave shape. An inlet 50 and an outlet 60 for inputting and outputting the fabric 200 are formed between the frame 10 and the end cap 20. The inlet 50 and the outlet 60 are arranged opposite to each other, that is, the fabric enters from the inlet 50 and moves forward under the drive of the cooling rollers 40 and is output from the outlet 60.

[0023] In this embodiment, while the fabric moves forward under the drive of the cooling roller 40, the cooling roller 40 cools and lowers the temperature of the fabric. (Refer to...) Figures 5 to 7 As shown, specifically, the cooling roller 40 includes a cooling roller body 42, a hollow threaded tube 41 disposed in the inner cavity of the cooling roller body 42, and an outer support layer 44 disposed on the outer surface of the cooling roller body 42. The hollow threaded tube 41 is arranged axially in the inner cavity of the cooling roller body 42. The outer circumferential surface of the hollow threaded tube 41 is provided with a spiral channel arranged spirally along the axial direction. Cooling water inlet 47 and cooling water outlet 48 are respectively provided at both ends of the cooling roller body 42. The cooling water inlet 47 and cooling water outlet 48 are respectively connected to the two ends of the spiral channel. The inner wall of the cooling roller body 42 is in contact with the outer surface of the spiral channel. The thermal conductivity of the cooling roller body 42 and the hollow threaded tube 41 is higher than that of the outer support layer 44. The hardness of the outer support layer 44 is greater than that of the cooling roller body 42 and the hollow threaded tube 41.

[0024] External cooling water enters one end of the spiral channel of the hollow threaded tube 41 through the cooling water inlet 47. The cooling water flows forward spirally along the spiral channel. During the flow, the cooling water exchanges heat with the fabric 200 wrapped around the outer surface of the cooling roller, cooling the fabric 200. The cooled water after heat exchange flows out from the cooling water outlet 48, that is, new cooling water continuously enters the cooling roller, and the cooled water after heat exchange flows out from the cooling roller.

[0025] To reduce the temperature difference between the two ends of the cooling roller, in this embodiment, the cooling roller body 42 and the hollow threaded tube 41, which are in contact with the cooling water, are made of a material with a high thermal conductivity. This improves the cooling water transfer efficiency and reduces the thermal deviation generated at both ends along the length of the cooling roller. For example, the cooling roller body 42 and the hollow threaded tube 41 are made of aluminum. Simultaneously, the hollow threaded tube 41 has a hollow pipe structure, which reduces the overall weight of the cooling roller. Furthermore, to ensure the strength of the cooling roller, the outer support layer 44 is made of a material with a high hardness coefficient, such as stainless steel.

[0026] Reference Figure 7 As shown, in order to further improve the cooling efficiency of the cooling roller, a graphene coating 43 is also provided between the cooling roller body 42 and the outer support layer 44. That is, the graphene coating 43 is formed as a part that contacts the refrigerant, and its thickness is 0.1 to 2 mm.

[0027] Reference Figure 3 As shown, in this embodiment, a cooling air device 30 is provided at the bottom of the inner cavity of the frame 10. The cooling air device 30 is used to provide upward-flowing cold air to the cooling roller. During the cooling process of the fabric 200 passing through the cooling roller, the fabric 200 is also cooled by the upward-flowing cold air to compensate for the uneven cooling that may occur when the fabric 200 passes through the cooling roller.

[0028] Reference Figure 3 and Figure 4 As shown, specifically, the air cooling device 30 includes a main air inlet pipe 31, a first fan 32, an air collecting pipe 33, and multiple air outlet pipes 34. One end of the main air inlet pipe 31 is connected to an external air cooling source, and the other end of the main air inlet pipe 31 is connected to the inner cavity of the air collecting pipe 33. The air collecting pipe 33 is a closed cavity structure, that is, the air collecting pipe 33 is a cavity structure with both ends sealed and the inside is hollow. Multiple air outlet pipes 34 are arranged directly below multiple cooling rollers. Multiple air outlet pipes 34 are connected to the inner cavity of the air collecting pipe 33 through branch pipes. Multiple air outlet holes 341 are spaced apart on the upper end face of the air outlet pipes 34.

[0029] External cooling air is drawn into the inner cavity of the main air inlet duct 31 by the first fan 32, and moves forward along the main air inlet duct 31 into the collecting air duct 33. Under the suction of the first fan 32, the external cold air entering the inner cavity of the collecting air duct 33 enters multiple air outlet ducts 34 above the collecting air duct 33, and is ejected upwards from multiple air outlet holes 341 on the upper end face of the air outlet ducts 34. The ejected cold air comes into contact with the woven fabric 200 wound on the cooling rollers, exchanging heat with the woven fabric 200 and cooling it. In this embodiment, since there are multiple air outlet ducts 34, and these multiple air outlet ducts 34 are arranged directly below multiple cooling rollers, the cooling method combining the air outlet ducts 34 and the cooling rollers can improve the cooling efficiency of the woven fabric and ensure the uniformity of cooling.

[0030] Reference Figure 2 and Figure 3 As shown, in this embodiment, in order to further improve the smooth and stable upward flow of external cooling air, the air cooling device 30 also includes a second fan 36, an air collecting hood 35, and an exhaust pipe 37. The air collecting hood 35 is disposed at the top of the end cover 20, and the inner cavity of the air collecting hood 35 is connected to the inner cavity of the end cover 20. The second fan 36 is fixedly installed at the top of the air collecting hood 35, the air inlet of the second fan 36 is connected to the inner cavity of the air collecting hood 35, and the air outlet of the second fan 36 is connected to one end of the exhaust pipe 37.

[0031] As the cold air ejected from the bottom air outlet 34 flows upward, the second fan 36 generates suction above the fabric, so that the cold air ejected from the bottom air outlet 34 can flow upward more concentratedly, allowing the cold air to exchange heat with the fabric better. The cold air after heat exchange enters the upper air collection hood 35 and is discharged outward from the exhaust pipe 37.

[0032] Reference Figure 5 and Figure 7 As shown, in some embodiments, in order to improve the corrosion resistance of the cooling roller, a copper layer 45 and a nickel layer 46 are provided on the outer surface of the outer support layer 44. The copper layer 45 and the nickel layer 46 are arranged sequentially from the inside to the outside. The copper layer 45 provides a stable adhesion substrate for the nickel layer 46, preventing the subsequent nickel layer 46 from peeling off due to poor adhesion.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
