[0002] A tension-free continuous conveying roller is used in the textile dyeing and finishing industry. It can move in a circle to roll and process fabrics. It is used for descaling, bleaching, dyeing and finishing before dyeing and finishing.

[0003] When processing fabrics, the equipment in the prior art needs to process the fabrics in pieces, and the continuous long fabrics are cut into short fabrics of about 50 meters. The fabrics need to be processed piece by piece, which is inefficient and has high costs such as labor, water and steam. At present, a washing machine that can continuously process fabrics has also been developed on the market. Through the movement of the guide roller, the fabric can be continuously passed through the washing machine. After the fabric passes through the guide roller, the fabric will be subjected to warp tension. The more guide rollers the fabric passes through, the greater the increase in warp tension. However, when the fabric has a wrinkling effect, the tension generated by the guide roller will cause the wrinkle to be radially stretched and deformed, causing the wrinkle to lose its original shape.

[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

When in use, the nozzle 4 is connected to a water pump, which pumps water from the nozzle 4 into the fabric inlet pipe 3. The water flows toward the inside of the cylinder 1 through the guide member 5. When the fabric to be processed is conveyed into the fabric inlet pipe 3, the fabric will contact with the water flow, and the water flow will drive the fabric to move, so that the fabric is continuously conveyed to the cylinder 1 for processing, and the use of fabric guide rollers to transport the fabric is avoided, thereby avoiding deformation of the crepe fabric due to excessive tension.

[0023] When the cylinder 1 is turned over, the turning strip 2 can stir the water flow and can also squeeze and beat the fabric to treat the fabric.

[0024] like Figure 3As shown, the width of the cloth-turning strip 2 gradually decreases from one end to the other end, the narrower end of the cloth-turning strip 2 faces the cloth-outlet end of the cylinder 1, and the wider end of the cloth-turning strip 2 faces the cloth-inlet end of the cylinder 1. The cloth-turning strip 2 will make a circular motion with the cylinder 1. When the cloth-turning strip 2 located at the bottom of the cylinder 1 rotates with the cylinder 1 and moves to the middle of the cylinder 1, the side of the cloth-turning strip 2 will become the top surface of the cloth-turning strip 2. Since the width of the cloth-turning strip 2 gradually decreases from one end to the other end, the top surface of the cloth-turning strip 2 that moves to the middle of the cylinder 1 will present a water-guiding slope, the side of the cloth-turning strip 2 facing the cloth-inlet end of the cylinder 1 is higher, and the side of the cloth-turning strip 2 facing the cloth-outlet end of the cylinder 1 is lower, which can further guide the flow of water in the cylinder 1, and the water flow can drive the fabric, thereby making the cloth transport effect of the conveying roller better.

[0025] like Figure 1 , Figure 2 As shown, the driving assembly includes a sprocket 12 fixedly connected to the cylinder 1 and a plurality of supporting roller assemblies 6, the supporting roller assembly 6 includes a roller and a wheel seat, and a first supporting ring 7 is provided at one end of the sprocket 12, and a second supporting ring 8 is provided on the outer wall of the cloth outlet end of the cylinder 1, the lower part of the first supporting ring 7 is supported by two supporting roller assemblies 6 and the end of the first supporting ring 7 away from the cylinder 1 is also in contact with the supporting roller assembly 6, which can support the rotation of the cylinder 1 and prevent the roller from moving toward the side of the cloth inlet pipe 3, and the lower part of the second supporting ring 8 is supported by two supporting roller assemblies 6, the sprocket 12 is connected to the motor through a chain, the motor drives the sprocket 12, the sprocket 12 drives the cylinder 1, and the cylinder 1 rotates on the supporting roller assembly 6, thereby realizing the rotation of the cylinder 1, and the rotation direction and rotation speed of the cylinder 1 can be controlled by controlling the motor.

[0026] like Figure 3 As shown, the interior of the flap strip 2 is hollow, and a plurality of holes are provided on the surface of the flap strip 2. The hollow interior of the flap strip 2 can contain liquid, and the liquid enters the interior of the flap strip 2 through the holes. During the lifting process of the flap strip 2, the flap strip 2 will move above the liquid level, and the water inside the flap strip 2 will flow out from the holes to flush the fabric, thereby improving the treatment effect of the fabric.

[0027] like Figure 4 As shown, the cloth inlet pipe 3 includes an inlet portion 13, which is located at one end of the cloth inlet pipe 3 away from the cylinder 1, and the inner diameter of the inlet portion 13 gradually decreases from one end to the other end. The end of the inlet portion 13 with a smaller inner diameter faces the cylinder 1, and the end of the inlet portion 13 with a larger inner diameter is away from the cylinder 1. That is, the larger opening of the inlet portion 13 can better guide the fabric material into the cloth inlet pipe 3, making the transmission more stable.

[0028] like Figure 4As shown, the nozzle 4 is located on the inlet portion 13 and communicates with the interior of the inlet portion 13, the guide member 5 includes an integrally formed fixed flange 9 and a guide ring 10, the fixed flange 9 is fixedly connected to the end of the inlet portion 13 away from the cylinder 1, the guide ring 10 extends into the interior of the inlet portion 13 and forms a gap with the inner wall of the inlet portion 13, the water flow generated by the water pump enters from the nozzle 4 into the gap between the inner wall of the inlet portion 13 and the guide ring 10, the gap at the opening of the inlet portion 13 is closed by the fixed flange 9, and the water flow can only move toward the cylinder 1, thereby driving the fabric.

[0029] like Figure 1 As shown, a plurality of reinforcing ribs 11 are provided on the outer wall of the cylinder 1 along the length direction of the cylinder 1. The reinforcing ribs 11 are sleeved on the outer wall of the cylinder 1.
