Description

Technical Field

[0001] The utility model relates to the technical field of yarn dyeing equipment, in particular to a paper feeding and flattening mechanism and a yarn dyeing machine. Background Art

[0002] Printing and transfer is a mature process for transferring patterns onto fabrics. Fabrics can be directly placed into a printing and transfer machine for color transfer. However, the warp yarns in a rapier loom are continuous and cannot be fed into the transfer machine in the same way as fabrics by being disconnected. Moreover, the warp yarns in a rapier loom have tension requirements, and the production speed is very slow. The yarns cannot be in contact with a high-temperature roller for a long time. Therefore, traditional printing machines cannot be used. As a result, a warp yarn transfer device is needed to dye the yarns. That is, the yarns are threaded between two transfer papers to form a whole, and then the whole is transported to a high-temperature roller so that the two transfer papers are heated to transfer the dye onto the yarns, thus completing the printing and dyeing between the yarns. However, before the transfer paper enters into contact with the high-temperature roller, the yarns and the transfer paper are not fully flattened, which leads to poor dyeing effect of the yarns. Summary of the Utility Model

[0003] In order to solve the above technical problems or at least partially solve the above technical problems, the present application provides a paper feeding and flattening mechanism and a yarn dyeing machine.

[0004] In a first aspect, the present application provides a paper feeding and flattening mechanism, including a paper feeding and flattening roller and a brush assembly. A plurality of mounting grooves are distributed along the circumference of the roller body of the paper feeding and flattening roller, and the mounting grooves extend along the length direction of the paper feeding and flattening roller;

[0005] The brush assembly includes a fixing strip and a plurality of brushes. Each fixing strip is fixed in each mounting groove, and the plurality of brushes are sequentially fixed on the surface of the fixing strip facing away from the mounting groove.

[0025] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, in order to thoroughly understand the embodiments of the present utility model.

[0026] Please refer to Figures 1 to 3 Figures 1 to 3 , the present application provides a paper feeding and flattening mechanism, including a paper feeding and flattening roller 10 and a brush hair assembly 20. A plurality of mounting grooves 10a are distributed along the circumference of the roller body of the paper feeding and flattening roller 10, and the mounting grooves 10a extend along the length direction of the paper feeding and flattening roller 10; the brush hair assembly 20 includes a fixing strip 21 and a plurality of brush hairs 22. A fixing strip 21 is fixed in each mounting groove 10a, and a plurality of brush hairs 22 are sequentially fixed on the surface of the fixing strip 21 facing away from the mounting groove 10a.

[0027] Exemplarily, the fixing strip 21 can be fixed in the mounting groove 10a by a detachable connection method. For example: a sticky layer is provided in the mounting groove 10a, and then the fixing strip 21 is placed into the mounting groove 10a to contact the sticky layer. After the sticky layer solidifies, the fixing strip 21 can be fixed in the mounting groove 10a.

[0028] Exemplarily, the paper feeding and flattening roller 10 is mounted on the frame in a non-powered driving manner, and only rotates by the pulling of the transfer paper to achieve the flattening of the surface of the transfer paper.

[0029] Based on the above technical features, in the paper feeding and flattening mechanism, by providing the mounting grooves 10a on the roller body of the paper feeding and flattening roller 10 and installing the fixing strip 21 with the brush hairs 22 installed therein in the mounting grooves 10a, when the transfer paper needs to be placed into the high-temperature roller for heat transfer printing, the transfer paper pulls the paper feeding and flattening roller 10 to rotate, so that the brush hairs 22 provided on the paper feeding and flattening roller 10 are driven to rotate, thereby realizing the flattening of the transfer paper. The structure is simple and the operation is convenient, and it can fully flatten the yarn and the transfer paper, making the dyeing effect of the yarn better.

[0030] In a possible implementation manner, the fixing strip 21 has opposite first and second ends. A first region is formed from the first end of the fixing strip 21 to the center of the fixing strip 21, and a second region is formed from the second end of the fixing strip 21 to the center of the fixing strip 21. The brush hairs 22 located in the first region and the brush hairs 22 located in the second region are inclined to both sides with the central axis of the fixing strip as the distribution.

[0031] It should be noted that based on dividing the fixing strip 21 into a first region and a second region with the center of the fixing strip 21, and setting the brush hairs 22 in the first region and the second region to be inclined to both sides with the central axis of the fixing strip as the distribution, when the paper feeding and flattening roller 10 rotates to drive the brush hairs 22 to flatten the surface of the transfer paper, the forces exerted by the brush hairs 22 in the first region and the second region on the transfer paper will be from the middle to both sides, so that the flattening effect on the transfer paper is better.

[0032] In a possible implementation, the bristles 22 form an angle with the center line of the fixing strip 21, and the range of the angle is between 5° and 8°.

[0033] In a possible implementation, fixing holes for fixing the bristles 22 are provided on the fixing strip 21. In this way, the bristles are inserted into the fixing holes of the fixing strip, so that the bristles are detachably connected to the fixing strip, with a simple structure, convenient disassembly and assembly, and facilitating subsequent replacement of the bristles.

[0034] In a possible implementation, it further includes a rotating rod and a sleeve fixed to the frame. One end of the rotating rod is connected to the end of the paper feeding and flattening roller. The sleeve has an inner cavity, and the end of the rotating rod away from the paper feeding and flattening roller extends into the inner cavity and can rotate relative to the inner wall of the inner cavity.

[0035] Exemplarily, by connecting the rotating rods 60 to both ends of the paper feeding and flattening roller 10, fixing sleeves on the frame, and then extending the ends of the rotating rods away from the paper feeding and flattening roller into the inner cavities of the sleeves, since the rotating rods can rotate relative to the inner walls of the inner cavities, the paper feeding and flattening roller is rotatably mounted on the frame. When the transfer paper is pulled, the paper feeding and flattening roller is pulled to rotate, thereby driving the bristles fixed on the paper feeding and flattening roller to flatten the surface of the transfer paper.

[0036] In a possible implementation, it further includes rollers. The rollers are sleeved on the part of the rotating rod located in the inner cavity, and the rollers are in contact with the inner wall of the inner cavity, so that the paper feeding and flattening roller is rotatably connected to the frame. In this way, when the transfer paper pulls the paper feeding and flattening roller to rotate, the rotating rod 60 is driven to rotate. Since the rotating rod 60 is connected to the paper feeding and flattening roller 10, the paper feeding and flattening roller 10 follows to rotate, thereby using the multiple bristles 22 provided on the paper feeding and flattening roller 10 to flatten the surface of the transfer paper. In addition, the rollers 70 sleeved on the connecting part will rotate in the inner cavity of the sleeve 30 following the rotation of the connecting rod 50, ensuring better synchronism between the rotating rod 60 and the paper feeding and flattening roller 10.

[0037] In a possible implementation, an outer edge 30a is provided on the outer periphery of the sleeve 30, and a connection hole for fixedly connecting with the frame is provided on the outer edge 30a. In this way, after the outer edge 30a of the sleeve 30 is in contact with the surface of the frame, the connection hole on the outer edge 30a and the mounting hole on the frame, and then fasteners are sequentially passed through the mounting hole and the connection hole, thereby fixedly connecting the sleeve 30 to the frame, with a simple structure and convenient disassembly and assembly.

[0038] The embodiment of the present disclosure also provides a yarn dyeing machine, including the paper feeding and flattening mechanism in the above embodiment.

[0039] According to the yarn dyeing machine of the embodiments of the present disclosure, adopting the above paper feeding and flattening mechanism, the technical effects are the same as those of the above paper feeding and flattening mechanism, which will not be elaborated here.

[0040] It can be understood that the above embodiments only represent the preferred embodiments of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, the above technical features can be freely combined, and several deformations and improvements can also be made, which all belong to the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made to the scope of the claims of the present utility model shall fall within the scope covered by the claims of the present utility model.
