Description
Technical Field
[0001] This utility model relates to the field of textile dyeing technology, specifically to a double-heated roller yarn transfer machine. Background Technology
[0002] Traditional yarn dyeing involves immersing the yarn in a large amount of water containing dissolved dye and using a large amount of inorganic salts for dyeing. Afterwards, it must undergo heating and washing processes to complete the dyeing. This dyeing process not only has low dye utilization but also generates large amounts of water vapor and waste from fuel combustion, which is resource-intensive and causes air pollution, thus harming the environment.
[0003] To address this, the textile industry has developed yarn transfer printing equipment, drawing inspiration from fabric printing transfer technology. This equipment allows for dyeing without water, improving production efficiency. Current yarn transfer printing equipment, however, involves sandwiching transfer paper and yarn between a heated roller and felt for coloring. This method has the following problems:
[0004] 1. Coloring is achieved using felt in conjunction with heated rollers. The additional pressure exerted by the felt on the yarn increases the load on the loom. When there is a large amount of yarn and a high warp density, the tension of the yarn on the heated rollers is very high. As a result, the yarn path is sometimes tight and sometimes loose due to the resistance of the felt, leading to problems such as false weft during the weaving process.
[0005] Second, the yarn is arranged in a unidirectional direction, while the felt uses a twill weave. The felt contacts the transfer paper, and the uneven surface of the felt slightly moves the yarn on the inside of the transfer paper, interfering with the yarn's direction and causing uneven yarn distribution, which severely affects the dyeing effect. Furthermore, the yarn is heated on one side by a roller, while the other side is covered by felt, resulting in inconsistent temperatures on both sides during the yarn transfer process, leading to uneven dyeing of the yarn.
[0006] Third, the continuous operation of the felt will carry away a lot of heat, exacerbate energy consumption, and worsen the high-temperature environment in the workshop. Utility Model Content
[0007] In view of the problems existing in the prior art, the purpose of this invention is to provide a dual-heating roller yarn transfer machine to improve the yarn coloring effect.
[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0012] The colored paper unit includes a first paper feeding roller, a second paper feeding roller, a first paper taking roller, and a second paper taking roller disposed within an installation space. Transfer paper fed from the first paper feeding roller passes sequentially through the first heating roller and the second heating roller, and is then wound onto the first paper taking roller. Transfer paper fed from the second paper feeding roller passes sequentially through the first heating roller and the second heating roller, and is then wound onto the second paper taking roller. Transfer paper fed from the first paper feeding roller adheres tightly to the first heating roller as it passes through it, and transfer paper fed from the second paper feeding roller adheres tightly to the second heating roller as it passes through it.
[0013] The yarn roller is used to feed the yarn to be transferred into the heating unit for coloring. The yarn to be transferred passes through the yarn roller and then sequentially through the first heating roller and the second heating roller. The yarn to be transferred is sandwiched between two transfer papers.
[0014] The first heating roller and the second heating roller rotate synchronously and are driven by the first drive assembly.

[0016] The first transmission chain is arranged in a closed loop. The inner side of the first transmission chain meshes with the first drive sprocket, the auxiliary gear, and the first gear or the second gear, while the outer side of the first transmission chain meshes with the second gear or the first gear.
[0017] The first paper feeding roller and the first paper receiving roller are driven by the second drive assembly to achieve synchronous rotation, and the second paper feeding roller and the second paper receiving roller are driven by the third drive assembly to achieve synchronous rotation.

The third gear is sleeved on one end of the first paper feeding roller, and the fourth gear is sleeved on one end of the first paper receiving roller. The second transmission chain is arranged in a closed loop, and the inner side of the second transmission chain meshes with the second drive sprocket, the third gear, and the fourth gear.
[0019] The third drive assembly includes a third power component, a third transmission chain, a third drive sprocket, a fifth gear, and a sixth gear. The third power component is fixed on the frame. The third drive sprocket is connected to the output shaft of the third power component. The fifth gear is sleeved on one end of the second paper feeding roller, and the sixth gear is sleeved on one end of the second paper receiving roller. The third transmission chain is arranged in a closed loop, and the inner side of the third transmission chain meshes with the third drive sprocket, the fifth gear, and the sixth gear.
[0020] The dual-heating roller yarn transfer machine also includes a tension adjustment assembly, which includes a first tension rod and a second tension rod. The first tension rod and the second tension rod are connected as a whole by a connecting block at both ends. The connecting block is rotatably mounted on the frame.
[0021] The transfer paper and the yarn to be transferred pass through the first tension bar and the second tension bar before entering the heating unit.
[0022] The tension adjustment assembly is driven by a tension drive assembly, which includes a tension power component, a reducer, a synchronous gear, and a spur gear. The tension power component is connected to the reducer, the reducer is connected to the synchronous gear, the synchronous gear meshes with the spur gear, and the spur gear is connected to the connecting block.
[0023] The dual-heating roller yarn transfer machine also includes two brush rollers disposed in the installation space. The brush rollers are provided with multiple rows of brushes arranged along the axial direction of the brush rollers. The two brush rollers are a first brush roller and a second brush roller. The transfer paper released from the first paper feeding roller enters the heating unit after passing through the first brush roller, and the transfer paper released from the second paper feeding roller enters the heating unit after passing through the second brush roller.
[0024] The frame is also equipped with a heat shield, a hot gas absorption pipe and a suction motor. A housing is provided on one side of the frame, and an exhaust port is provided on the top of the housing. The heat shield is located on the outer periphery of the heating unit. The hot gas absorption pipe is close to the heating unit and has several through holes. The suction motor is located inside the housing and is connected to the end of the hot gas absorption pipe.
[0025] By adopting the above solution, this utility model provides a new yarn transfer printing machine that eliminates the use of felt, avoiding the adverse effects caused by felt. Simultaneously, this utility model adds a heating roller, giving the yarn transfer printing machine two heating rollers. During heat transfer, the transfer paper on one side of the yarn is in close contact with the first heating roller, and the transfer paper on the other side of the yarn is in close contact with the second heating roller. This ensures that both sides of the transfer paper receive direct heating from the heating rollers, allowing the color on the transfer paper to be evenly transferred to both sides of the yarn, thus improving the dyeing effect of the yarn.

[0043] This embodiment discloses a dual-heating roller yarn transfer machine, which includes a frame 10, a heating unit 20, a color paper unit 30, and a yarn roller 40.
[0044] The frame 10 defines an installation space to facilitate the installation of the heating unit 20, the colored paper unit 30, and the yarn roller 40.
[0045] The heating unit 20 is used to heat the transfer paper and yarn 63 so as to transfer the color on the transfer paper onto the yarn 63. The heating unit 20 includes a first heating roller 21 and a second heating roller 22 disposed in the installation space. A passage gap is provided between the first heating roller 21 and the second heating roller 22, and the first heating roller 21 and the second heating roller 22 rotate in opposite directions.
[0046] The colored paper unit 30 includes a first paper feeding roller 31, a second paper feeding roller 33, a first paper taking roller 32, and a second paper taking roller 34 disposed in the installation space. The transfer paper fed from the first paper feeding roller 31 passes sequentially through the first heating roller 21 and the second heating roller 22 and is then wound onto the first paper taking roller 32. The transfer paper fed from the second paper feeding roller 33 passes sequentially through the first heating roller 21 and the second heating roller 22 and is then wound onto the second paper taking roller 34. When the transfer paper fed from the first paper feeding roller 31 passes through the first heating roller 21, it adheres tightly to the first heating roller 21. When the transfer paper fed from the second paper feeding roller 33 passes through the second heating roller 22, it adheres tightly to the second heating roller 22.
[0047] The yarn roller 40 is used to feed the yarn 63 to be transferred into the heating unit 20 for coloring. After passing through the yarn roller 40, the yarn 63 to be transferred passes through the first heating roller 21 and the second heating roller 22 in sequence. The yarn 63 to be transferred is sandwiched between the two transfer papers.
[0048] In this embodiment, the first heating roller 21 is positioned above the second heating roller 22. When the heating unit 20 is activated, the first heating roller 21 rotates clockwise, and the second heating roller 22 rotates counterclockwise. The first paper feeding roller 31 and the first paper taking roller 32 of the colored paper unit 30 are located on the left side of the heating unit 20, with the first paper feeding roller 31 positioned above the first paper taking roller 32. The second paper feeding roller 33 and the second paper taking roller 34 are located on the right side of the heating unit 20, with the second paper feeding roller 33 positioned above the second paper taking roller 34. The yarn roller 40 is located on the left side of the heating unit 20 and above the first paper feeding roller 31. After the transfer paper (hereinafter referred to as first transfer paper 61) fed from the first paper feed roller 31, the transfer paper (hereinafter referred to as second transfer paper 62) fed from the second paper feed roller 33, and the yarn 63 introduced via the yarn roller 40 enter the heating unit 20, the first transfer paper 61 and the second transfer paper 62 sandwich the yarn 63 between them, with the first transfer paper 61 located on the left and the second transfer paper 62 located on the right. When passing through the first heating roller 21, the first transfer paper 61 is in close contact with the first heating roller 21, and the high temperature of the first heating roller 21 transfers the color on the first transfer paper 61 to the left side of the yarn 63. Although the first heating roller 21 also heats the second transfer paper 62, the temperature of the second transfer paper 62 is not high after passing through the first transfer paper 61 and the yarn 63. Therefore, after passing through the first heating roller 21, the color on the second transfer paper 62 may not be completely transferred to the right side of the yarn 63. To address this, this invention adds a second heating roller 22. The first transfer paper 61, yarn 63, and second transfer paper 62, after passing through the first heating roller 21, pass through the second heating roller 22. At this time, the second transfer paper 62 is in close contact with the second heating roller 22, and the high temperature of the second heating roller 22 transfers the color from the second transfer paper 62 to the right side of the yarn 63. After exiting the second heating roller 22, the first transfer paper 61 is wound into the first take-up roller 32, and the second transfer paper 62 is wound into the second take-up roller 34. The dyed yarn 63 can be wound into a take-up device or directly fed into the loom. In this invention, because the first heating roller 21 and the second heating roller 22 heat and transfer both sides of the yarn 63 respectively, the coloring on both sides of the yarn 63 is more uniform, resulting in a better coloring effect.
[0049] In addition to being arranged vertically as shown in the figure of this embodiment, the first heating roller 21 and the second heating roller 22 can also be arranged horizontally or in other ways. When the first heating roller 21 and the second heating roller 22 are arranged in other ways in the installation space, the arrangement positions of the first paper feeding roller 31, the first paper receiving roller 32, the second paper feeding roller 33, the second paper receiving roller 34 and the yarn roller 40 in the installation space also change accordingly.
[0050] In this embodiment, the first heating roller 21 and the second heating roller 22 rotate synchronously and are driven by the first driving component 23. The first driving component 23 can drive the first heating roller 21 and the second heating roller 22 to rotate synchronously, ensuring that the yarn is heated evenly during the transfer process, avoiding tension fluctuations or color differences in the transfer caused by differences in roller speed, and significantly improving the consistency of the finished product.
[0051] Specifically, the first drive assembly 23 includes a first power component 231, a first drive sprocket 232, an auxiliary gear 233, a first gear 234, a second gear 235, and a first transmission chain 236. The first power component 231 is fixed to the frame 10. The first drive sprocket 232 is connected to the output shaft of the first power component 231. The first gear 234 is sleeved on one end of the first heating roller 21, and the second gear 235 is sleeved on one end of the second heating roller 22. The auxiliary gear 233 is rotatably connected to the frame 10. The first transmission chain 236 is arranged in a closed loop. The inner side of the first transmission chain 236 meshes with the first drive sprocket 232, the auxiliary gear 233, and the first gear 234 (or the second gear 235), and the outer side of the first transmission chain 236 meshes with the second gear 235 (or the first gear 234).
[0052] The auxiliary gear 233 is configured to alter the path of the first transmission chain 236, enabling it to drive the first heating roller 21 and the second heating roller 22 to rotate in opposite directions while the first transmission chain 236 is in operation. This, in turn, helps to pull the yarn and transfer paper forward. When the outer side of the first transmission chain 236 meshes with the first gear 234, the auxiliary gear 233 is positioned above the first gear 234. When the outer side of the first transmission chain 236 meshes with the second gear 235, the auxiliary gear 233 is positioned below the second gear 235.
[0053] After the heating unit 20 is started, the first power component 231 drives the first drive sprocket 232 to rotate. The first drive sprocket 232 drives the first gear 234 and the second gear 235 to rotate. The first heating roller 21 rotates with the first gear 234, and the second heating roller 22 rotates with the second gear 235, thereby realizing the heating and conveying of the transfer paper and yarn 63.
[0054] In this embodiment, the first paper feeding roller 31 and the first paper taking roller 32 are driven by the second driving component 35 to achieve synchronous rotation, and the second paper feeding roller 33 and the second paper taking roller 34 are driven by the third driving component 36 to achieve synchronous rotation.
[0055] The second drive assembly 35 includes a second power component 351, a second transmission chain 352, a second drive sprocket 353, a third gear 354, and a fourth gear 355. The second power component 351 is fixed to the frame 10. The second drive sprocket 353 is connected to the output shaft of the second power component 351. The third gear 354 is sleeved on one end of the first paper feeding roller 31, and the fourth gear 355 is sleeved on one end of the first paper taking roller 32. The second transmission chain 352 is arranged in a closed loop, and its inner side meshes with the second drive sprocket 353, the third gear 354, and the fourth gear 355. After the second power component 351 is started, it drives the second drive sprocket 353 to rotate. The second drive sprocket 353 drives the third gear 354 and the fourth gear 355 to rotate via the second transmission chain 352. The first paper feeding roller 31 feeds paper as the third gear 354 rotates, and the first paper taking roller 32 takes paper as the fourth gear 355 rotates.
[0056] The third drive assembly 36 includes a third power component 361, a third transmission chain 362, a third drive sprocket 363, a fifth gear 364, and a sixth gear 365. The third power component 361 is fixed to the frame 10. The third drive sprocket 363 is connected to the output shaft of the third power component 361. The fifth gear 364 is sleeved on one end of the second paper feed roller 33, and the sixth gear 365 is sleeved on one end of the second paper take-up roller 34. The third transmission chain 362 is arranged in a closed loop, and its inner side meshes with the third drive sprocket 363, the fifth gear 364, and the sixth gear 365. After the third power component 361 is started, it drives the third drive sprocket 363. The third drive sprocket 363 drives the fifth gear 364 and the sixth gear 365 to rotate via the third transmission chain 362. The second paper feed roller 33 feeds paper as the fifth gear 364 rotates, and the second paper take-up roller 34 takes paper as the sixth gear 365 rotates.
[0057] In this embodiment, the first power component 231, the second power component 351, and the third power component 361 all use servo motors as power sources. Of course, other power components capable of driving the transmission chain in the prior art can also be used, and there is no limitation on this.
[0058] Building upon the above, the dual-heated roller yarn transfer machine also includes a tension adjustment component 50. By operating the tension adjustment component 50, a force can be applied to the passing yarn, thereby adjusting the yarn tension to meet different tension requirements during the transfer process.
[0059] Specifically, the tension adjustment assembly 50 includes a first tensioning rod 51 and a second tensioning rod 52. The two ends of the first tensioning rod 51 and the second tensioning rod 52 are connected as a whole by a connecting block 53. There is a gap between the first tensioning rod 51 and the second tensioning rod 52. The connecting block 53 is rotatably mounted on the frame 10. After the transfer paper and the yarn 63 to be transferred pass through the gap between the first tensioning rod 51 and the second tensioning rod 52, they enter the heating unit 20.
[0060] The tension adjustment component 50 is driven by the tension drive component 54, which includes a tension power element 541, a reducer 542, a synchronous gear 543, and a spur gear 544. The tension power element 541 is connected to the reducer 542, the reducer 542 is connected to the synchronous gear 543, the synchronous gear 543 meshes with the spur gear 544, and the spur gear 544 is connected to the connecting block 53. In this embodiment, the tension power element 541 is a handwheel. When the user turns the handwheel, the handwheel drives the synchronous gear 543 to rotate via the reducer 542. The synchronous gear 543 drives the spur gear 544 to rotate, and the rotation of the spur gear 544 drives the first tension rod 51 and the second tension rod 52 to rotate together. This causes the first tension rod 51 and the second tension rod 52 to apply force to the yarn, thereby achieving adaptive adjustment of the yarn tension, which is beneficial to improving the yarn transfer effect. Of course, the tension power element 541 can also be implemented by a motor, thereby realizing the automatic adjustment of the tension adjustment component 50.
[0061] like Figure 2 and Figure 7 As shown, the double-heated roller yarn transfer machine also includes two brush rollers located within the installation space. Each brush roller has multiple rows of brushes 39 arranged along its axial direction. When the transfer paper pressure is high, the brushes 39 collapse; when the pressure is low, the brushes 39 lift the transfer paper, thus regulating the paper tension. The two brush rollers are a first brush roller and a second brush roller. The transfer paper discharged from the first paper feed roller 31 passes through the first brush roller 37 and enters the heating unit 20. The transfer paper discharged from the second paper feed roller 33 passes through the second brush roller 38 and enters the heating unit 20.
[0062] like Figure 8 and Figure 9As shown, a heat dissipation assembly is also installed on the frame. This assembly includes a heat shield 71, a hot air absorption pipe 72, and a suction motor 73. A housing 11 is located on one side of the frame, with an exhaust port 12 on the top of the housing 11. The heat shield 71 is positioned around the heating unit 20, and the hot air absorption pipe 72 is close to the heating unit 20. The hot air absorption pipe 72 has several through holes. The suction motor 73 is located inside the housing 11 and is connected to the end of the hot air absorption pipe 72. After the suction motor 73 starts, it absorbs the hot air around the heating unit 20 into the housing 11 through the hot air absorption pipe 72 and discharges it through the exhaust port 12 at the top of the housing 11. The heat shield 71 relatively isolates the heating unit, significantly reducing heat loss and effectively reducing energy consumption. Then, the suction motor 73 and the hot air absorption pipe 72 discharge the hot air around the heating unit, preventing a high-temperature environment in the workshop.
[0063] In summary, the key feature of this invention is that it provides a novel yarn transfer machine that eliminates the use of felt, avoiding the adverse effects caused by felt. Furthermore, this invention adds a heating roller, giving the yarn transfer machine two heating rollers. During heat transfer, the transfer paper on one side of the yarn 63 is in close contact with the first heating roller 21, and the transfer paper on the other side of the yarn 63 is in close contact with the second heating roller 22. This ensures that both sides of the transfer paper receive direct heating from the heating rollers, allowing the color on the transfer paper on both sides of the yarn 63 to be evenly transferred to both sides of the yarn 63, thus improving the coloring effect of the yarn 63.
[0064] The above description is merely an embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
