DETAILED DESCRIPTION

[0020] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0021] Please refer to Figures 1-4 The present application provides a technical scheme:

[0022] Please refer to Figures 1-4 As shown in the figure, an environment-friendly low-energy high-color-fastness cold rolling dyeing device, comprising a dip dyeing device 1, an extrusion roller 2, the number of which is two, which is arranged above the dip dyeing device 1, and the cloth is uniformly dyed and the excess dye is removed after passing through the two extrusion rollers 2; an arc plate 3 is arranged on both sides of the extrusion roller 2, the two ends of the arc plate 3 are fixedly installed at one end of the same direction of the two extrusion rollers 2, and the cross section is arranged in an arc shape; a guide telescopic rod 4 is arranged at the midpoint position of the two extrusion rollers 2, and the telescopic end of the mounting block 7 is fixedly installed on the inner wall of the arc plate 3.

[0023] After the cloth passes through the dip dyeing tank, it moves under the pull of the winding roller, the elastic force of the arc plate 3 causes the two extrusion rollers 2 to extrude the cloth, if it encounters relatively thick cloth, the two ends of the arc plate 3 will be slightly opened, the telescopic end of the guide telescopic rod 4 will perform a contraction movement, wherein the guide telescopic rod 4 acts as a fixed point, so that the opening amplitude of the two ends of the arc plate 3 is the same, thereby uniformly extruding the upper and lower surfaces of the cloth, so that the dye is uniformly distributed, and at the same time, the dye can be fully contacted with the fiber by extrusion, and the elastic force of the arc plate 3 and the synergistic effect of the guide telescopic rod 4 can automatically adjust according to the thickness of the cloth. When encountering thick cloth, the device can automatically adapt without frequent manual intervention, making the printing and dyeing process more smooth and efficient.

[0024] At the same time, it can promote the better combination of dye molecules and fiber molecules, which can help to improve the firmness of dyeing and enhance the color fastness, so that the color of the cloth is not easy to fall off in the subsequent use process, such as washing and rubbing.

[0025] Please refer to Figures 1-4 The top of the dip dyeing device 1 is fixedly installed with a mounting bracket 5, the inner wall of the mounting bracket 5 is fixedly installed with a mounting block 7 at the center position, and the fixed end of the mounting block 7 is fixedly installed on one side of the mounting block 7.

[0026] The mounting frame 5 is fixed on the top of the dip dyeing device 1, and provides a stable mounting base for the mounting block 7 and the guide rod 6, which can bear the weight of the mounting block 7 and the guide rod 6, and ensure that the device will not be unstable due to the weight of the components or vibration during operation.

[0027] Referring to Figures 1-3 , two guide rods 6 are fixedly installed on the inner wall of the mounting frame 5, and the extrusion rollers 2 are slidingly connected to the outer wall of the guide rods 6.

[0028] The two guide rods 6 are fixedly installed on the inner wall of the mounting frame 5, and the extrusion rollers 2 are slidingly connected to the outer wall of the guide rods 6, which makes the extrusion rollers 2 have a clear movement trajectory during operation. When the cloth passes between the two extrusion rollers 2 under the pulling of the winding roller, the extrusion rollers 2 will be subjected to various forces such as friction force of the cloth and its own gravity. The guide rods 6 can ensure that the extrusion rollers 2 can only move in the vertical direction or the preset direction, avoiding the instability of the extrusion rollers 2 during operation, such as deviation and shaking.

[0029] Referring to Figures 1-3 , the material of the arc-shaped plate 3 is spring steel.

[0030] The spring steel has excellent elasticity. When the extrusion rollers 2 extrude the cloth, it may produce certain irregular pressure changes. Its material is spring steel, which can elastically deform when subjected to these external forces, and quickly recover to its original state after the force disappears.

[0031] Referring to Figure 2 , the impurity groove 8 is provided on the dip dyeing device 1, the dip dyeing groove is provided on the dip dyeing device 1, the filter screen 9 is fixedly installed between the impurity groove 8 and the dip dyeing groove, the water pipe 10 is fixedly installed between the dip dyeing groove and the impurity groove 8, and the suction pump 11 is fixedly installed on the water pipe 10.

[0032] The existence of the water pipe 10 and the suction pump 11 enables the dyeing liquid to circulate between the dip dyeing groove and the impurity groove 8. The dyeing liquid filtered by the filter screen 9 can return to the dip dyeing groove for cloth dyeing, improving the utilization rate of the dyeing liquid. For high-priced dyes, this recycling method can significantly reduce production costs, and at the same time meet the requirements of environmentally friendly printing and dyeing devices, reducing dyeing liquid waste.

[0033] Referring to Figure 2 , the inner bottom wall of the impurity groove 8 is inclined, one side of the impurity groove 8 is hingedly connected with a sealing door 12, and a handle 14 is fixedly installed on the sealing door 12.

[0034] The inner bottom wall of the impurity tank 8 is inclined, which enables impurities to naturally gather on the lower side of the impurity tank 8 under the action of gravity. When it is necessary to clean the impurities, the inclined design facilitates the smooth flow of the impurities out of the impurity tank 8, without the need for manual collection of the impurities from various corners by using tools, greatly improving the cleaning efficiency.

[0035] The impurity tank 8 is hinged on one side with a sealing door 12, and is provided with a handle 14, so that an operator can easily open the sealing door 12 by the handle 14. In combination with the inclined design of the inner bottom wall, after the sealing door 12 is opened, the impurities can be more conveniently cleaned out, whether by using a flushing method or directly shoveling out the impurities with a tool, and the operation is more convenient.

[0036] Referring to Figures 1-2 The inner wall of the dip dyeing tank is fixedly provided with a pressing roller 13.

[0037] In the printing and dyeing process, the pressing roller 13 can press the cloth into the dyeing liquid of the dip dyeing tank, so that the cloth is in full contact with the dyeing liquid. Especially for some cloth with thick texture or tight structure, through the extrusion of the pressing roller 13, the dyeing liquid can better penetrate into the inside of the fibers of the cloth. This helps to improve the uniformity of the distribution of the dyeing liquid in the cloth, avoids uneven dyeing, and thus improves the printing and dyeing quality.
