Description

Technical Field

[0001] The utility model relates to the technical field of cloth dyeing machines, in particular to a pressing roller mechanism of a cloth dyeing machine. Background Art

[0002] During the printing and dyeing process, the fabric needs to be immersed in the dyeing tank. After the printing and dyeing is completed, the fabric is output from the dyeing tank, and then the excess dye on the fabric is squeezed out of the fabric to speed up the drying of the fabric.

[0003] Under normal circumstances, in order to squeeze the dye out of the cloth, two parallel pressure rollers are usually used. The cloth is allowed to pass through the gap between the two pressure rollers. The two pressure rollers rotate synchronously in opposite directions. The pressure rollers squeeze the cloth to squeeze the dye on the cloth. At this time, the pressure rollers also provide power for the cloth to move forward, so that the cloth continues to move forward.

[0004] In the above scheme, the two pressing rollers can only squeeze a single layer of cloth. Since the thickness of the cloth is relatively small, in order to achieve the effect of squeezing the cloth, the gap between the two pressing rollers needs to be designed to be very small. Under normal circumstances, the two pressing rollers are in rigid contact when squeezing the cloth. The single layer of cloth carries less dye, and the pressing roller mechanism is less effective in scraping off the dye from the cloth.

[0005] Therefore, how to design a pressure roller mechanism to improve the extrusion effect of the cloth dye has become a technical problem that needs to be solved urgently by people in this field. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The present embodiment provides a roller pressing mechanism for a cloth dyeing machine, which is mainly used to roll cloth to improve the effect of removing dye from the cloth.

[0025] like Figure 1 As shown, it includes a mounting base 1, a conveying roller 2 is rotatably connected to the mounting base 1, and a driving mechanism for driving the conveying roller 2 to rotate, a squeezing roller group 6 is slidably connected to the mounting base 1, the axis of the squeezing roller group 6 is parallel to the axis of the conveying roller 2, and also includes an adjusting mechanism for driving the squeezing roller group 6 to move to change the gap between the conveying roller 2 and the peripheral wall of the squeezing roller group 6, the squeezing roller group 6 is provided with an air jet channel 611 sprayed toward the cloth, when the cloth dye is squeezed, the cloth passes through the gap between the squeezing roller group 6 and the conveying roller 2, and the peripheral wall of the conveying roller 2 abuts against the peripheral wall of the squeezing roller group 6.

[0026] Through the above arrangement, the gap between the conveying roller 2 and the squeezing roller group 6 can be adjusted by using the adjustment mechanism. While facilitating the passage of the cloth, the position of the squeezing roller group 6 can be changed to be suitable for squeezing dyes for cloths of different thicknesses, thereby broadening the scope of application of the cloth.

[0027] Generally, the cloth is thinner, and the gap between the squeezing roller group 6 and the conveying roller 2 is smaller. The cloth carries less dye per unit cross-sectional area, and it is difficult for the squeezing roller group 6 to squeeze the dye out of the cloth. In this case, the jet channel 611 on the squeezing roller group 6 is used to spray high-pressure gas onto the cloth, so that the dye on the cloth can be sprayed out, thereby improving the effect of separating the dye from the cloth.

[0028] In order to realize the driving of the conveying roller 2, in this embodiment, as shown in FIG. Figure 1 As shown, the driving mechanism includes a motor 3 , and the output shaft of the motor 3 is fixedly connected to the rotating shaft of the conveying roller 2 .

[0029] In order to improve the separation effect of the cloth and the dye, in this embodiment, as Figure 3 and Figure 5 As shown, the extrusion roller group 6 includes an air storage drum 61, an extrusion cylinder 62 and an elastic pad 63, wherein the extrusion cylinder 62 is sleeved on the outside of the air storage drum 61 and is rotatably connected to the peripheral wall of the air storage drum 61, the elastic pad 63 is sleeved on the peripheral wall of the extrusion cylinder 62 in a cylindrical shape, the jet channel 611 is arranged on the side wall of the air storage drum 61, and the elastic pad 63 and the peripheral wall of the extrusion cylinder 62 are provided with a plurality of air holes 64 for gas to be ejected outward. When the cloth is extruded, the peripheral wall of the elastic pad 63 pushes the cloth to be squeezed on the peripheral wall of the conveying roller 2, and the elastic pad 63 is deformed.

[0030] Through the above arrangement, since the peripheral wall of the conveying roller 2 abuts against the peripheral wall of the elastic pad 63 and elastic deformation occurs at the contact position between the conveying roller 2 and the elastic pad 63, as the conveying roller 2 rotates, the cloth can be attached to the surface of the elastic pad 63, driving the cloth to move forward. At this time, the flexible cooperation of the elastic pad 63 and the conveying roller 2 can strengthen the squeezing of the cloth and improve the effect of separating the dye from the cloth.

[0031] While the conveying roller 2 rotates, the extrusion cylinder 62 can be driven to rotate around the axis of the air storage drum 61 through the elastic pad 63. At this time, the air holes 64 on the peripheral wall of the elastic pad 63 and the extrusion cylinder 62 are aligned with the jet channel 611 one by one, which facilitates the high-pressure gas to be sprayed out of the extrusion roller group 6, thereby improving the separation effect of the cloth and the dye.

[0032] In order to further improve the separation effect of the cloth and the dye, in this embodiment, Figure 3 As shown, the squeezing roller group 6 is located at the upper left of the conveying roller 2, and the horizontal plane where the highest point of the conveying roller 2 is located is between the horizontal planes formed by the lowest point and the highest point of the squeezing roller group 6, respectively. A first guide roller 51 is provided at the upper left of the squeezing roller group 6, and a second guide roller 52 is provided at the upper right of the conveying roller 2. The cloth passes around the first guide roller 51, the squeezing roller group 6, the conveying roller 2 and the second guide roller 52 in sequence and is conveyed from left to right. Specifically, the opening of the jet channel 611 is vertically downward.

[0033] With the above settings, Figure 3 As shown, when the cloth passes through the gap between the squeezing roller group 6 and the conveying roller 2, the cloth is at its lowest point at the bottom of the squeezing roller group 6. When the cloth extends toward the contact point between the squeezing roller group 6 and the conveying roller 2, the cloth tilts to the upper right. When the squeezing roller group 6 and the conveying roller 2 squeeze the cloth, the dye on the cloth flows downward along the tilt direction of the cloth, and then flows in the opposite direction to just below the squeezing roller group 6. Since the cloth extends to the lower right after passing through the first guide roller 51, at this time, the dye on the cloth also gathers to just below the squeezing roller group 6 under the action of gravity. Since the jet channel 611 opens downward, the dye accumulated on the cloth can be blown down vertically, thereby improving the separation effect of the cloth and the dye.

[0034] In order to realize the installation of the squeezing roller set 6, in this embodiment, as shown in FIG. Figure 2 and Figure 4 As shown, the mounting seats 1 located on both sides of the extrusion roller group 6 are provided with slide grooves 11 arranged in the horizontal direction, and the first slider 41 and the second slider 42 are respectively installed in the slide grooves 11 of the two mounting seats 1, wherein the first slider 41 and the second slider 42 are both slidably connected to the slide grooves 11, and the two ends of the air storage drum 61 are respectively fixed on the first slider 41 and the second slider 42.

[0035] It is worth mentioning here that the advantage of the fixed connection between the air storage drum 61 and the first slider 41 and the second slider 42 is that the rotation of the air storage drum 61 can be limited so that the opening of the jet channel 611 is always vertically downward, pointing to the lowest point of the squeezing roller group 6, thereby facilitating the blowing of the dye on the cloth downward and improving the separation effect of the cloth and the dye.

[0036] In order to ensure that the first slider 41 and the second slider 42 slide stably in the slide groove 11, in this embodiment, Figure 4 As shown, the bottom wall and the top wall of the slide groove 11 are both provided with a limiting groove 111, and the first slider 41 and the second slider 42 are both provided with a limiting rib 43 inserted into the limiting groove 111, wherein the side wall of the limiting rib 43 abuts against the side wall of the limiting groove 111.

[0037] In order to deliver high-pressure gas to the inside of the gas storage drum 61, in this embodiment, Figure 4 and Figure 5 As shown, the end wall of the air storage drum 61 is provided with an air inlet pipe 612 connected to the inner cavity of the air storage drum 61, and the second slider 42 is provided with a plug hole 421 arranged along the axial direction of the air storage drum 61. The air inlet pipe 612 extends to the outside of the second slider 42 through the plug hole 421. The air inlet pipe 612 is connected to an external air source to provide high-pressure gas to the air storage drum 61.

[0038] In order to adjust the position of the squeezing roller set 6, thereby adjusting the gap between the squeezing roller set 6 and the conveying roller 2, in this embodiment, as shown in FIG. Figure 2 and Figure 4 As shown, a positioning seat 12 is fixedly provided on the side wall of the mounting seat 1 , a threaded rod 13 is rotatably connected to the positioning seat 12 , a threaded hole 411 for the threaded rod 13 to pass through is provided on the first sliding block 41 , and the threaded rod 13 is threadedly connected to the threaded hole 411 .

[0039] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
