[0024] The following is in conjunction with the appendix Figures 1-4 The present invention provides a more detailed description of an embodiment of an anti-winding guide tube for a dyeing machine.

[0025] A fabric dyeing machine anti-tangling guide tube, such as Figures 1 to 3 As shown, it includes a circular interface 1 and a square tube 2. The circular interface 1 is located at both ends of the square tube 2, and multiple connecting holes 11 are distributed around the circumference of the circular interface 1. The square tube 2 has several longitudinal grooves 21 inside, which are equidistantly distributed on the four sides of the square tube 2. A transition connecting pipe 3 connects the circular interface 1 and the square tube 2. The transition connecting pipe 3 gradually widens from the circular cross-section at both ends to the polygonal cross-section in the middle.

[0026] Specifically, the circular interface 1, the transition connecting pipe 3 and the square pipe body 2 are integrally formed, the transition connecting pipe 3 is gradually widened from the circular cross section at the two ends to the polygonal cross section at the middle part, so that the pipe body changes from the same diameter of the “circular” cross section in the traditional technology to the side widening structure of the regular polygon of the “square”, so that the fabric can be expanded in the weft direction after entering the guide pipe, and the edge rolling phenomenon is reduced. In addition, the cross-sectional shapes of the circular interface 1, the transition connecting pipe 3 and the square pipe body 2 are different, and as the cross-sectional shape of the guide pipe changes, the fabric state changes, the fabric state changes continuously, and the problem that the fabric with high elasticity and high tightness is prone to creases is effectively solved.

[0027] In the embodiment, as shown in Figure 4 The square pipe body 2 is further provided with a vortex breaking portion 22 on the inner wall of the four walls, the vortex breaking portion 22 is a conical structure, and the vortex breaking portion 22 protrudes from the inner wall of the square pipe body 2. The tip of the conical structure of the vortex breaking portion 22 is directed to the center of the square pipe body 2, and the tip of the conical structure is provided with a circular arc transition surface.

[0028] Specifically, the vortex breaking portion 22 is provided with a plurality of groups, wherein the tips of the vortex breaking portions 22 between every two groups are oppositely arranged, so that the connecting line of the vortex breaking portions 22 with opposite tips forms a cross, which is convenient for preventing the formation of vortex. The conventional anti-vortex technology is mostly a cross plate, but the guide pipe of the present application needs to guide the cloth, and the structure of the cross plate will hinder the guiding of the cloth. Therefore, the tips of the vortex breaking portions 22 are oppositely arranged, so that the center of the square pipe body 2 is left empty and the cloth can be guided. At the same time, since the vortex breaking portion 22 is nested in the square pipe body 2, under the influence of the shape of the square pipe body 2, the water flow can only flow in the square pipe body 2 and cannot cause vortex. In addition, the longitudinal grooves 21 are arranged on the inner walls of the four walls of the square pipe body 2, and the conical structure of the vortex breaking portion 22 protrudes from the inner wall of the square pipe body 2. When the water flow passes through the conical structure, it is blocked by the resistance and flows into the longitudinal grooves 21, so as to disperse the water flow, which is also conducive to reducing the impact of the water flow and avoiding the formation of vortex.

[0029] In the embodiment, the included angle between the conical structure of the vortex breaking portion 22 and the square pipe body 2 is 60°.

[0030] Specifically, the included angle between the conical structures of the vortex breaking portions 22 is also 60°. The purpose of setting the angle to 60° is to block the water flow when the water flow flows through, which can further improve the limitation of the water flow and avoid the formation of vortex.

[0031] In the embodiment, the two ends of the circular interface 1 are matched with the cloth inlet and cloth outlet of the cloth dyeing machine respectively, and the circular interface 1 is fixedly connected with the cloth inlet and cloth outlet of the cloth dyeing machine through flanges.

[0032] Specifically, the purpose of setting the circular interface 1 is to facilitate the adaptive connection with the cloth inlet and cloth outlet of the dyeing machine, and the connecting hole 11 on the circular interface 1 can be fixed with the flange through locking screws, so that the circular interface 1 can be quickly installed.

[0033] In order to further improve the cleaning ability of the square tube body 2, a hydrophobic layer is also coated on the inner wall of the square tube body 2. The purpose of setting the hydrophobic layer is to avoid the square tube body 2 from being contaminated by the dyeing liquid, and also to facilitate subsequent cleaning.

[0034] The working principle of the utility model:

[0035] Before the cloth enters the guide cloth pipe, the cloth to be dyed is sent into the inlet end of the guide cloth pipe and fully contacts with the dyeing liquid, so that the cloth is quickly soaked; then the nozzle on the cloth dyeing machine pushes the cloth into the square tube body 2 part of the guide cloth pipe, and realizes good contact between the cloth and the dyeing liquid by means of the flow of the dyeing liquid; at the same time, the cloth in the square tube body 2 is prevented from excessive bending or twisting under the action of the longitudinal groove 21 and the vortex breaking part 22, so as to avoid knotting and winding; finally, the cloth is discharged, so that the cloth after completing dyeing and cleaning leaves the guide cloth pipe from the outlet end and enters the dyeing machine again to complete the subsequent work. The anti-winding guide cloth pipe of the utility model is set as a round-to-square structure, and the two ends are set as circular interfaces 1, which facilitates the connection with the cloth inlet and cloth outlet of the dyeing machine, and ensures that the cloth can enter and exit smoothly. The middle square tube body 2 design increases the contact area between the cloth and the pipe wall, reduces the knotting of the cloth caused by the flow dynamics of the dyeing liquid; at the same time, the longitudinal groove 21 is arranged on the inner wall of the square tube body 2, which helps the dyeing liquid to penetrate and distribute on one hand, and provides more anti-winding points on the other hand, reduces the problem of fiber entanglement in the guide cloth pipe.

[0036] The embodiments of the specific embodiment are the preferred embodiments of the application, and are not limited to the protection scope of the application, wherein the same parts are indicated by the same reference numerals. Therefore: any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
