Description

Technical Field

[0001] This application relates to the field of fabric coating and cooling technology, specifically a cooling device for fabric after coating. Background Technology

[0002] In the textile industry, after the fabric undergoes coating treatment, it usually experiences a relatively high temperature. At this time, a cooling system is needed to reduce the temperature of the fabric to ensure the smooth progress of subsequent processing steps. Common cooling devices include water cooling systems, which use circulating cooling water to reduce the temperature of the fabric and are often used in large-scale production lines, and air cooling systems, which use fans or air circulation equipment to blow cold air to remove the heat from the fabric.

[0003] A search revealed that publication number CN109263076A discloses a coating equipment, including a winding assembly. The winding assembly comprises a cooling roller for cooling the coated material and a winding machine for winding the cooled coated material. A heat pump is installed between the cooling roller and the raw material drying drum to extract heat from the cooling roller into the raw material drying drum. By using a heat pump to transport heat from the cooling roller to the raw material drying drum, a single heat pump can both cool the coated material and improve the toughness and transparency of the composite material.

[0004] However, if a cooling roller is used to cool the fabric after coating, the fabric may become too loose and wrinkle before passing through the cooling roller. At the same time, during the long process of cooling the coated fabric, the surface temperature of the cooling roller may not be able to drop in time, resulting in an increase in temperature and thus reducing the cooling effect.

[0005] Therefore, it is necessary to provide a cooling device for fabrics after coating to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0040] Please see Figure 1-6 The embodiments provided by this utility model are as follows:

[0041] A cooling device for fabric after coating includes a workbench 1. A first support frame 2 is mounted on one side of the top surface of the workbench 1. A drive mechanism 3 is mounted on the side wall of the first support frame 2. Two transmission rollers 4 for guiding the coated fabric are mounted on the top surface of the first support frame 2. The drive mechanism 3 drives the transmission rollers to rotate on the top of the first support frame 2. The drive mechanism 3 includes a fixed plate 31, a servo motor 32, a drive wheel 33, a belt 34, and driven wheels 35. The fixed plate 31 is fixedly mounted on the side wall of the first support frame 2 by screws. The servo motor 32 is fixedly mounted on the side wall of the fixed plate 31. The inside of the drive wheel 33 is keyed to the output shaft of the servo motor 32. Two driven wheels 35 are provided. Both driven wheels 35 are driven to the drive wheel 33 by the belt 34. The inside of the two driven wheels 35 are keyed to the end shafts of the transmission rollers 4. The end shafts of the two transmission rollers 4 are rotatably connected on the top of the first support frame 2 by bearings.

[0042] The servo motor 32 drives the drive wheel 33 to rotate, and the belt 34 drives the two driven wheels 35 to rotate, thereby enabling the two transmission rollers 4 on the first support frame 2 to rotate, so as to transport the coated fabric from one side to the other side for cooling.

[0043] During transportation, the tension of the coated fabric needs to be adjusted to prevent wrinkles during cooling. An adjustment mechanism 5 for adjusting the coated fabric is installed on one side of the first support frame 2. The adjustment mechanism 5 includes a support plate 51, a rotating shaft 52, an adjustment frame 53, an adjustment roller 54, a first support 55, an electric push rod 56, and a second support 57. The support plate 51 is fixedly installed on the side wall of the first support frame 2. The rotating shaft 52 is fixedly connected to both side walls of the adjustment frame 53. The rotating shaft 52 is rotatably connected to the side wall of the support plate 51 through bearings. An adjustment roller 54 is rotatably installed on one side of the adjustment frame 53 through bearings. The other side of the adjustment frame 53 is fixedly installed to the first support 55 at the center. The inside of the first support 55 is rotatably connected to the end of the telescopic shaft of the electric push rod 56. The second support 57 is installed on the side wall of the inner crossbeam of the first support frame 2. The tail of the electric push rod 56 is rotatably connected to the inside of the second support 57.

[0044] The principle is as follows:

[0045] When the surface tension of the coated fabric is too loose, the telescopic shaft of the electric push rod 56 is shortened inward, which drives the first support 55 to move toward the electric push rod 56. This causes the bottom of the adjusting frame 53 to rotate inward, and the adjusting roller 54 installed on the top of the adjusting frame 53 to rotate outward. This changes the distance between the adjusting roller 54 and the transport roller, thereby tightening the loose coated fabric to ensure that the coated fabric can maintain a smooth surface.

[0046] A second support frame 6 is fixedly installed on the workbench 1 on the other side of the first support frame 2. A cooling mechanism 7 for cooling the coated fabric is rotatably installed on the top of the second support frame 6. The cooling mechanism 7 includes two cooling rollers 71, a liquid inlet assembly, and a liquid outlet assembly. The two ends of the two cooling rollers 71 are respectively connected to the liquid inlet assembly and the liquid outlet assembly. The liquid inlet assembly and the liquid outlet assembly provide the cooling rollers 71 with low-temperature coolant and discharge the coolant with increased temperature to ensure that the surface of the cooling rollers 71 is at a low temperature, thereby enabling the cooling treatment of the coated fabric.

[0047] The cooling roller 71 includes an outer cylinder 711 and an inner cylinder 715. Multiple heat-conducting fins 716 are integrally formed at equal angles along the inner wall of the outer cylinder 711. All heat-conducting fins 716 abut against the outer wall of the inner cylinder 715. Liquid-guiding grooves 717 are correspondingly formed at both ends of the inner cylinder 715 according to the angle of the heat-conducting fins 716 on the outer cylinder 711. When the outer cylinder 711 comes into contact with the coated fabric, its surface temperature rises, thereby transferring heat to each heat-conducting fin 716. On the 6th, multiple heat-conducting fins 716 reduce their temperature by flowing coolant through the gaps between them. Meanwhile, since they are in contact with the inner cylinder 715, the inner cylinder 715 can be made of copper tubes with higher thermal conductivity to absorb heat from the multiple heat-conducting fins 716. In turn, the coolant flowing in the cavity inside the inner cylinder 715 can cool the inner cylinder 715. The inner cylinder 715 and the multiple heat-conducting fins 716 indirectly provide a better cooling effect for the outer cylinder 711, thereby ensuring the cooling treatment of the coated fabric.

[0048] The liquid inlet assembly and the liquid outlet assembly have the same structure. The liquid inlet assembly includes a rotary joint 72 and a coolant pipe 73. One end of the rotary joint 72 is connected to the liquid guide pipe 714, and the other end of the rotary joint 72 is connected to the coolant pipe 73.

[0049] Coolant is supplied to the cooling roller 71 through the coolant pipe 73, so that the coolant can enter the cooling roller 71 through the rotary joint 72, providing the cooling roller 71 with a long-term low temperature effect.

[0050] The outer cylinder 711 has a connecting plate 712 installed at both ends. The outer side wall of the connecting plate 712 is fixedly connected to a liquid guide pipe 714, which is connected to the inside of the outer cylinder 711 and the inside of the inner cylinder 715.

[0051] It is worth noting that the inner side of the connecting plate 712 is integrally formed with a plug ring. The side wall of the plug ring has an annular groove, and a sealing ring 713 is fitted on the annular groove. The plug ring is inserted into the inner ends of the outer cylinder 711. The liquid guide pipes 714 are rotatably connected to the top of the second support frame 6 through bearings. The sealing ring 713 and the plug ring are inserted into the two ends of the outer cylinder 711 to ensure the sealing between the outer cylinder 711, the inner cylinder 715 and the connecting plate 712, thereby preventing leakage during use.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
