It can be understood that the above scheme can be used to avoid wrinkles in the cloth during the winding process, which affects the uniformity of dyeing, and can also be used to adjust the tension force for different cloths.

[0026] According to this specific embodiment, the winding roller 103 is rotatably installed inside the dyeing kettle body 101, and the unwinding roller 102 is rotatably installed inside the dyeing kettle body 101. A sealing cover 104 is rotatably installed on one side of the dyeing kettle body 101, and the dyeing kettle body 101 is sealed by the sealing cover 104. A feed inlet 105 and a discharge outlet 106 are also provided on the top of the dyeing kettle body 101. The unwinding roller 102 and the winding roller 103 are rotatably installed inside the dyeing kettle body 101 through a bracket, and a motor is also installed on the bracket on which the winding roller 103 is installed. The output end of the motor is connected to the winding roller 103, and the winding roller 103 and the unwinding roller 102 can be disassembled, so as to facilitate the installation. The cloth is taken out of or put into the dyeing kettle body 101; when dyeing the cloth, the cloth to be dyed is wound on the unwinding roller 102, and the unwinding roller 102 and the winding roller 103 are installed inside the dyeing kettle body 101, the free end of the cloth is connected to the winding roller 103, and then the sealing cover 104 is closed, and the treated carbon dioxide and dye enter the dyeing kettle body 101 through the feed port 105 to dye the cloth, and the excess carbon dioxide and part of the dye are discharged from the discharge port 106, and the winding roller 103 is driven to rotate by the motor, so that the cloth on the unwinding roller 102 is continuously transported and wound around the winding roller 103, so that the cloth can fully contact with the dye and improve the uniformity of dyeing.

[0027] The detection member 114 is arranged inside the dyeing kettle body 101, the fixed sleeve 108 is connected to the dyeing kettle body 101 through the detection member 114, the damping disc 113 is fixedly connected to the unwinding roller 102 and is located on one side of the unwinding roller 102, the moving rod 109 is slidably connected to the fixed sleeve 108 and is arranged on the fixed sleeve 108, the connecting rod 110 is slidably connected to the fixed sleeve 108 and is arranged on the fixed sleeve 108, and the two ends of the first spring 111 are respectively connected to the moving rod 109 and the connecting rod 110 is connected, the first spring 111 is located inside the fixing sleeve 108, the side pressure block 112 is fixedly connected to the connecting rod 110, contacts the damping disc 113, and is located on the side of the connecting rod 110 close to the damping disc 113; the tensioning assembly 107 is provided with two, the detection member 114 can detect the tension of the fabric, and drive the moving rod 109 to move according to the tension of the fabric; when the fabric is wound by the winding roller 103, the tension of the fabric is detected by the detection member 114, and when the fabric is not wound, the detection member 114 can detect the tension of the fabric. When being tensioned, the detection member 114 drives the moving rod 109 to move, so that the moving rod 109 squeezes the first spring 111. After being squeezed, the first spring 111 applies force to the connecting rod 110, thereby causing the side pressure block 112 to apply force to the damping disk 113, so that the friction between the side pressure block 112 and the damping disk 113 is increased, thereby increasing the damping when the damping disk 113 and the unwinding roller 102 rotate, and improving the tension of the cloth when the winding roller 103 winds the cloth, so as to maintain the appropriate tension of the cloth and avoid the winding roller 103 from rolling. 3. When the fabric is rolled up, wrinkles and overlaps may occur. Similarly, when the fabric is too tight, the detection member 114 drives the moving rod 109 to move in the opposite direction, thereby reducing the pressure on the first spring 111, thereby reducing the friction between the side pressure block 112 and the damping disk 113, reducing the damping when the unwinding roller 102 rotates, avoiding deformation, stretching, and tearing caused by excessive tension of the fabric, thereby achieving appropriate tensioning of the fabric during the dyeing and winding process, avoiding wrinkles and folds in the fabric rolled up by the winding roller 103, and causing uneven dyeing.

[0028] Secondly, the first limiting groove 115 is arranged on one side of the connecting rod 110; the second limiting groove 116 is arranged on one side of the moving rod 109; the limiting protrusion 117 is arranged on the inner side of the fixing sleeve 108, and is located on the side of the fixing sleeve 108 close to the first limiting groove 115 and the second limiting groove 116; the movement of the moving rod 109 and the connecting rod 110 is limited by the limiting protrusion 117, so that the moving rod 109 and the connecting rod 110 can only move in a straight line and cannot rotate.

[0029] At the same time, the shell 118 is fixedly connected to the dyeing kettle body 101, and is fixedly connected to the fixed sleeve 108, and is located inside the dyeing kettle body 101; the second spring 119 is connected to the shell 118 and is located inside the shell 118; the driving seat 120 is slidably connected to the shell 118, and is connected to the second spring 119, and is located at one end of the second spring 119, the moving seat 121 is connected to the moving rod 109, and is located on the side of the moving rod 109 close to the driving seat 120; the lifting component 122 is arranged on the top of the driving seat 120.

[0030] In addition, the seat body 123 is fixedly connected to the moving rod 109 and is located at one end of the moving rod 109 ; the roller 124 is rotatably connected to the seat body 123 , contacts the driving seat 120 , and is disposed on the seat body 123 .

[0031] Then, the lifting rod 125 is fixedly connected to the driving seat 120 and is located at a side of the driving seat 120 away from the second spring 119 ; the abutting rod 126 is disposed on the lifting rod 125 .

[0032] Then, the support 127 is fixedly connected to the lifting rod 125 and is located at a side of the lifting rod 125 away from the driving seat 120 ; the rotating shaft 128 is rotatably connected to the support 127 and is disposed on the support 127 .

[0033] The driving seat 120 is provided with an inclined surface on one side close to the roller 124, and the inclined surface is used to push the roller 124 to move when the driving seat 120 rises. The elasticity of the second spring 119 drives the driving seat 120 to move, so that the driving seat 120 drives the lifting rod 125, the support 127 and the rotating shaft 128 to rise, so that the rotating shaft 128 abuts against the bottom of the cloth, and the friction between the roller 124 and the driving seat 120 is reduced by the rotation of the roller 124, and the friction between the rotating shaft 128 and the cloth is reduced by the rotation of the rotating shaft 128.

[0034] Finally, the guide rod 129 is fixedly connected to the housing 118 and slidably connected to the drive seat 120 and penetrates the drive seat 120 ; the guide rod 129 guides the lifting and lowering of the drive seat 120 to improve the stability of the drive seat 120 during lifting and lowering.

[0035] When the waterless printing and dyeing device for fabric processing of the present invention is used, when the fabric is relaxed during the winding process of the winding roller 103, the fabric cannot apply force to the rotating shaft 128. At this time, the second spring 119 can drive the driving seat 120 to rise. During the rising process of the driving seat 120, the roller 124 is driven to move under the action of its upper inclined surface, thereby driving the seat body 123 and the moving rod 109 to move, so that the moving rod 109 squeezes the first spring 111, and then the first spring 111 applies force to the connecting rod 110 and the side pressure block 112, so that the friction between the side pressure block 112 and the damping disk 113 increases. At this time, the damping increases when the unwinding roller 102 rotates, thereby tensioning the fabric wound by the winding roller 103; when the fabric is too tensioned, the fabric The material applies a downward force to the rotating shaft 128, so that the rotating shaft 128 drives the support 127, the lifting rod 125 and the driving seat 120 to descend. During the descending process of the driving seat 120, the roller 124, the seat body 123 and the moving rod 109 lose their limit. At this time, the compression amount of the first spring 111 is reduced, and then the force applied to the connecting rod 110 and the side pressure block 112 is reduced, so that the friction between the side pressure block 112 and the damping disk 113 is reduced, thereby reducing the damping when the unwinding roller 102 rotates, thereby allowing the unwinding roller 102 to release the cloth more smoothly, alleviating the excessive tension of the cloth, and realizing automatic tensioning of the wound cloth, avoiding wrinkles and overlaps of the cloth on the winding roller 103, and affecting the uniformity of dyeing.

[0036] Second embodiment:

[0037] Based on the first embodiment, please refer to Figure 5 and Figure 6 , Figure 5 is a schematic structural diagram of the adjustment component of the second embodiment, Figure 6 2 is a schematic diagram of the installation structure of the lifting plate of the second embodiment. The detection member 114 of this embodiment further includes an adjustment component 201; the adjustment component 201 includes a lifting plate 202, a slider 203, a threaded rod 204 and a knob 205.

[0038] According to this specific embodiment, the adjusting component 201 includes a lifting plate 202 and a slider 203. The lifting plate 202 is slidably connected to the guide rod 129, and is connected to the second spring 119, and is sleeved on the guide rod 129; the slider 203 is fixedly connected to the lifting plate 202 and is located on one side of the lifting plate 202.

[0039] The threaded rod 204 is rotatably connected to the housing 118 , and is threadedly connected to the slider 203 and penetrates the slider 203 ; the knob 205 is fixedly connected to the threaded rod 204 and is located at one end of the threaded rod 204 .

[0040] According to this specific embodiment, since the tension required for fabrics of different materials is different, the threaded rod 204 is driven to rotate by rotating the knob 205, so that the threaded rod 204 drives the slider 203 to rise and fall, and the slider 203 drives the lifting plate 202 to rise and fall, thereby compressing or releasing the second spring 119. When the second spring 119 is compressed, the fabric needs a greater tension to compress the rotating shaft 128. This state is suitable for fabrics with a harder texture and not easy to deform, such as cotton, linen or synthetic fibers. These fabrics require a stronger tension during the dyeing process to ensure that the dye can penetrate evenly and avoid On the contrary, when the second spring 119 is released and is in a relatively relaxed state, a smaller tension of the cloth can cause the operation of the rotating shaft 128 and the entire device. This state is suitable for soft and easily deformed cloth, such as silk, gauze or some fine fabrics. If these cloths are subjected to excessive tension during dyeing, the cloth fibers may be damaged, deformed or stretched unnecessarily, affecting the final dyeing effect and product quality. The present invention can also enable the user to accurately adjust the tension degree and adjustment accuracy of the tensioning component 107 according to the material, thickness, desired dyeing effect and tension requirements of the cloth.
