[0002] When dyeing fabrics, they typically need to be immersed in the dye for a long time, and the dye must be kept at a high temperature to achieve optimal dyeing results. Fabrics can be immersed in the dye vat in rolls or dyed online. The latter method achieves better dyeing uniformity, but the dyeing equipment is large and expensive to purchase. The former dyeing equipment is relatively small and simple in structure. However, since the fabric is dyed in rolls, the degree of dye immersion varies from part to part, making uneven dyeing a common problem. Therefore, the soaking time must be increased, which consumes a lot of energy to maintain the high temperature of the dye. Summary of the Invention

[0005] The dyeing process of the utility model is as follows: take out the winding drum, and wind the fabric to be dyed on the drum body, and two baffles are used to constrain the two sides of the fabric. After winding is completed, the winding drum is placed in the dyeing vat through the lifting equipment, and the left segment is placed on the left supporting part, and the right segment is placed on the right supporting part.

At this time, the rubber gasket can play a sealing effect, and the dye in the dyeing vat does not cover the winding drum; then turn on the driver, and push the piston back and forth in the piston cylinder at a uniform speed and slowly. When When the piston moves toward the output end, the input end is under negative pressure. At this point, the one-way valve is closed, causing the dye channel and the inner cavity of the winding cylinder to be under negative pressure. This creates a pressure difference between the inside and outside of the fabric wrapped around the cylinder. Driven by this pressure difference, the dye in the dye vat is accelerated to penetrate deeper into the fabric until it enters the inner cavity through the opening. This process accelerates the dye's penetration and diffusion within the fabric, helping to speed up the dyeing process. When the piston moves toward the input end, the input end is under high pressure. At this point, the one-way valve is open, allowing the dye on the input side to flow through the one-way valve to the output end. Therefore, as the piston continuously pushes back and forth, the dye in the dye vat is continuously drawn into the inner cavity, significantly accelerating the dyeing efficiency of deep-layer fabrics, shortening the entire dyeing process, and effectively improving dyeing uniformity and quality.

[0006] Therefore, compared with the existing technology, the present invention has the following characteristics: 1. The present invention can increase the rate of dye penetration into deep-layer fabrics through pressure difference, which can significantly accelerate the dyeing efficiency of deep-layer fabrics, shorten the entire dyeing time, and thus achieve low energy consumption and energy-saving effects, and effectively improve the uniformity of dyeing and improve the dyeing quality of fabrics.

The outer sides of the two baffles are further extended with a left segment 230 and a right segment 240. The end of the left segment is provided with an inner cavity 250 extending into the interior of the cylinder body. The outer wall of the cylinder body is provided with a plurality of openings 260 communicating with the inner cavity.

After the push rod abuts against the right segment, the dye channel can be connected with the inner cavity. The outer side of the dye vat is also provided with a piston cylinder 500 and a piston 510 located inside it (see Figure 4 ), a piston rod 520 is fixed on the piston and passes through the piston cylinder. The other end of the piston rod is connected to a driver 530, which is specifically a servo electric cylinder. The output thrust is required to be at least 3000N. An output end 540 is provided at one end of the piston cylinder, and an input end 550 is provided at the other end. The output end is extended and connected to an output tube 560 connected to the dye in the dye vat, and the input end is extended and connected to an input tube 570 connected to the dye channel. A one-way valve is provided on the piston, so that the fluid on the input end side of the piston cylinder can enter the output end side through the one-way valve in one direction.

[0014] The dyeing process of this embodiment is as follows: take out the winding drum and wind the fabric to be dyed on the drum body. The two baffles are used to constrain the two sides of the fabric. After winding is completed, the winding drum is placed in the dye vat through the hoisting equipment, and the left segment is placed on the left supporting part, and the right segment is placed on the right supporting part. The upper sides of the two supporting parts are arc-shaped, which can play a supporting and positioning effect; then rotate the push rod to make it abut against the right segment, and push the left segment to abut against the left positioning column. At this time, the rubber gasket can play a sealing effect, and the dye in the dye vat does not cover the winding drum; then turn on the driver, and push the piston back and forth in the piston cylinder at a uniform speed and slowly. When the active When the piston moves toward the output end, the input end is under negative pressure. At this point, the one-way valve is closed, causing the dye channel and the inner cavity of the winding cylinder to be under negative pressure. This creates a pressure difference between the inside and outside of the fabric wrapped around the cylinder. Driven by this pressure difference, the dye in the dye vat is accelerated to penetrate deeper into the fabric until it enters the inner cavity through the opening. This process accelerates the dye's penetration and diffusion within the fabric, helping to speed up the dyeing process. When the piston moves toward the input end, the input end is under high pressure. At this point, the one-way valve is open, allowing the dye on the input side to flow through the one-way valve to the output end. Therefore, as the piston continuously pushes back and forth, the dye in the dye vat is continuously drawn into the inner cavity, significantly accelerating the dyeing efficiency of deep-layer fabrics, shortening the entire dyeing process, and effectively improving dyeing uniformity and quality.

[0018] It is obvious to those skilled in the art that the present invention can be modified in many ways, and such modifications are not considered to depart from the scope of the present invention. All such modifications obvious to those skilled in the art are intended to be included within the scope of the present claims.
