Description

Technical Field

[0001] This application relates to the field of printing and dyeing color fixing technology, specifically a fabric printing color fixing device applied to waterless printing and dyeing processes. Background Technology

[0002] In recent years, waterless dyeing and printing technology has gradually attracted attention in the industry as a new type of environmentally friendly technology. This process significantly reduces wastewater discharge and energy consumption by reducing or eliminating the washing process. After the fabric is printed, the print needs to be fixed, which requires a color-fixing device.

[0003] Existing fabric printing color-fixing devices, after fixing the fabric print at high temperatures, will cause the fabric temperature to rise, which will make the fabric soft and stretchy. As a result, the fabric cannot be rolled up smoothly, and wrinkles will appear on the roll-up roller, affecting the use of the fabric. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a fabric printing and color-fixing device for waterless dyeing processes. This device can cool and reduce the temperature of the fabric after high-temperature color-fixing, preventing the fabric from softening and becoming excessively stretchy during winding. This allows the winding roller to wind the fabric smoothly, avoiding wrinkles on the roller. This solves the problem in existing fabric printing and color-fixing devices where the fabric temperature rises after high-temperature color-fixing, causing the fabric to soften and become stretchy, making it difficult to wind smoothly and resulting in wrinkles on the winding roller, thus affecting the fabric's usability.

[0005] To achieve the aforementioned goal of cooling down the fabric after the temperature rises due to high-temperature color fixing, preventing the fabric from softening and becoming excessively stretchy during winding, and ensuring that the winding roller can smoothly wind up the fabric without wrinkles, this application provides the following technical solution: A fabric printing color fixing device for waterless dyeing processes, comprising a frame, wherein a high-temperature color fixing mechanism is provided at the bottom of the inner wall of the frame via a support frame, and a traction roller group is provided on one side of the high-temperature color fixing mechanism, the traction roller group being provided at the bottom of the inner wall of the frame via a support frame. The cooling roller assembly has two cooling rollers on one side, arranged vertically. Each cooling roller includes a cooling ring, which is rotatably mounted on the outer surface of the middle part of the cooling shaft. The cooling shaft has cooling pipes inside, and both ends of the cooling shaft are supported by fixed plates. The two ends of the cooling pipes are connected to an inlet pipe and an outlet pipe, respectively. One end of the inlet pipe and the outlet pipe are connected to the refrigeration circulation mechanism, which is located at the bottom of the inner wall of the frame. A take-up roller is located on one side of the cooling rollers, and the take-up roller is rotatably mounted at the bottom of the inner wall of the frame via a support frame.

[0006] The above solution uses cooling pipes to cool the cooling shaft, which then transfers the low temperature to the cooling rings. This allows the cooling rings of the upper and lower cooling rollers to contact the upper and lower surfaces of the fabric, thus cooling the fabric. This achieves the effect of cooling the fabric after the temperature rises due to high-temperature color fixing, preventing the fabric from softening and becoming too stretchy during winding. It also allows the winding roller to wind the fabric smoothly, avoiding wrinkles on the winding roller.

[0007] Furthermore, the cooling pipe is spirally arranged inside the cooling shaft along the axial direction of the cooling shaft, and the cooling pipe is made of copper.

[0008] The above solution uses a spirally arranged copper cooling pipe to increase the contact area with the cooling shaft, thereby improving heat transfer efficiency. The high thermal conductivity of copper allows it to quickly absorb heat from the cooling shaft, achieving a uniform cooling effect.

[0009] Furthermore, the two support shafts corresponding to the lower cooling roller are mounted on the bottom of the inner wall of the frame via a support frame, and the two support shafts corresponding to the upper cooling roller are mounted on one end of the inner telescopic rod of the first telescopic rod via a support frame. One end of the outer telescopic tube of the first telescopic rod is mounted on one end of the hydraulic rod, and the hydraulic rod is mounted on the top of the inner wall of the frame.

[0010] The above solution allows for the adjustment of the distance between the upper and lower cooling rollers by driving the first telescopic rod with a hydraulic rod, enabling the two cooling rollers to adapt to the cooling needs of fabrics of different thicknesses.

[0011] Furthermore, both the inlet pipe and the outlet pipe are made of deformable flexible hoses.

[0012] The above solution uses flexible hoses for the inlet and outlet pipes, which avoids damage to the inlet and outlet pipes due to rigid tension when adjusting the position of the cooling roller, thus ensuring the stability of the refrigerant circulation.

[0013] Furthermore, a plurality of heat exchange rings are provided on the outer surface of the middle part of the cooling shaft. The heat exchange rings are rotatably disposed within the inner wall of the heat exchange groove, which is opened on the inner wall of the middle part of the cooling ring. The size and specifications of the heat exchange rings and the heat exchange groove are adapted to each other. The axial direction of the heat exchange rings is the same as that of the cooling shaft. The heat exchange rings are made of copper.

[0014] The above scheme increases the contact area between the cooling ring and the cooling shaft by using a copper heat exchange ring and heat exchange groove, thereby improving the heat exchange efficiency between the cooling ring and the cooling shaft. The rotational engagement of the heat exchange ring and the heat exchange groove also improves the stability of the cooling ring rotating on the outer surface of the middle part of the cooling shaft.

[0015] Furthermore, a first spring is provided inside the first telescopic rod, with one end of the first spring located at one end of the inner wall of the outer telescopic tube of the first telescopic rod, and the other end of the first spring located at one end of the inner telescopic rod of the first telescopic rod.

[0016] Through the above scheme, the first spring provides elastic preload, so that the upper cooling roller always applies appropriate downward pressure, which ensures that the cooling roller and the fabric are in full contact for cooling while preventing excessive compression that could deform the fabric.

[0017] Furthermore, a tension roller is provided between the cooling roller and the traction roller group. The tension roller is rotatably mounted on one end of the inner telescopic rod of the second telescopic rod via a support frame. One end of the outer tube of the second telescopic rod is fixedly connected to the side wall of the frame via a support plate. A second spring is provided inside the second telescopic rod. One end of the second spring is located on one end of the inner wall of the outer telescopic tube of the second telescopic rod, and the other end of the second spring is located on one end of the inner telescopic rod of the second telescopic rod.

[0018] Through the above scheme, the tension roller can automatically adjust its position according to the change of fabric tension by means of the synergistic action of the second telescopic rod and the second spring. This allows the fabric to remain flat between the traction roller group and the cooling roller, preventing the fabric from entering between the two cooling rollers in a wrinkled state, which would prevent the fabric from contacting the cooling rollers evenly for cooling.

[0019] Furthermore, the cooling shaft is hollow in the middle.

[0020] The above solution, by hollowing out the middle of the cooling shaft, allows for stable heat exchange between the cooling shaft and the cooling ring, preventing the low temperature of the cooling shaft from being transferred to the middle of the cooling shaft, which would result in excessive energy consumption. This allows the cooling shaft to efficiently cool the cooling ring.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This fabric printing and color-fixing device, applied to waterless dyeing and printing processes, cools the cooling shaft through a cooling pipe. The cooling shaft then transfers the low temperature to the cooling ring, allowing the cooling rings of the upper and lower cooling rollers to contact the upper and lower surfaces of the fabric, thus cooling the fabric. This achieves the effect of cooling the fabric after the temperature rises due to high-temperature color fixing, preventing the fabric from softening and becoming too stretchy during winding, and allowing the winding roller to wind the fabric smoothly without wrinkles appearing on the winding roller.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1 , Figure 3 and Figure 4 This embodiment describes a fabric printing and color-fixing device for a waterless dyeing process, comprising a frame 1. A high-temperature color-fixing mechanism 2 is provided at the bottom of the inner wall of the frame 1 via a support frame. A traction roller group 3 is provided on one side of the high-temperature color-fixing mechanism 2. The traction roller group 3 is provided at the bottom of the inner wall of the frame 1 via a support frame. Two cooling rollers 4 are provided on one side of the traction roller group 3. The two cooling rollers 4 are distributed vertically. Each cooling roller 4 includes a cooling ring 401. The cooling ring 401 is rotatably mounted on the outer surface of the middle part of a cooling shaft 402. A cooling pipe 403 is provided inside the cooling shaft 402. Both ends of the cooling shaft 402 are provided with a support shaft 404 via a fixing plate.

[0034] Please see Figure 2 , Figure 4 and Figure 7The two ends of the cooling pipe 403 are connected to the inlet pipe 6 and the outlet pipe 7 respectively. One end of the inlet pipe 6 and the outlet pipe 7 are connected to the refrigeration circulation mechanism 8. The refrigeration circulation mechanism 8 is located at the bottom of the inner wall of the frame 1. A take-up roller 5 is provided on one side of the cooling roller 4. The take-up roller 5 is rotatably located at the bottom of the inner wall of the frame 1 through the support frame.

[0035] Please see Figure 3 , Figure 6 and Figure 7 The cooling pipe 403 is spirally arranged inside the cooling shaft 402 along the axial direction of the cooling shaft 402. The cooling pipe 403 is made of copper. The spiral arrangement of the copper cooling pipe 403 can increase the contact area with the cooling shaft 402 and improve the heat conduction efficiency. The high thermal conductivity of copper can quickly absorb the heat of the cooling shaft 402 and achieve a uniform cooling effect.

[0036] Please see Figure 3 and Figure 4 The two support shafts 404 corresponding to the lower cooling roller 4 are set at the bottom of the inner wall of the frame 1 through a support frame. The two support shafts 404 corresponding to the upper cooling roller 4 are set at one end of the inner telescopic rod of the first telescopic rod 10 through a support frame. One end of the outer telescopic tube of the first telescopic rod 10 is set at one end of the hydraulic rod 9. The hydraulic rod 9 is set at the top of the inner wall of the frame 1. By driving the first telescopic rod 10 through the hydraulic rod 9, the distance between the upper cooling roller 4 and the lower cooling roller 4 can be adjusted, so that the upper and lower cooling rollers 4 can adapt to the cooling needs of fabrics of different thicknesses.

[0037] Please see Figure 2 , Figure 3 and Figure 7 Both the inlet pipe 6 and the outlet pipe 7 are made of deformable flexible hoses. The use of deformable flexible hoses for the inlet pipe 6 and the outlet pipe 7 avoids damage to the inlet pipe 6 and the outlet pipe 7 due to rigid pulling of the pipes when adjusting the position of the cooling roller 4, thus ensuring the stability of the refrigerant circulation.

[0038] Please see Figure 6 and Figure 7 Multiple heat exchange rings 405 are provided on the outer surface of the middle part of the cooling shaft 402. The heat exchange rings 405 are rotatably disposed in the inner wall of the heat exchange groove 406, which is opened on the inner wall of the middle part of the cooling ring 401. The size and specifications of the heat exchange rings 405 and the heat exchange groove 406 are adapted to each other. The axial direction of the heat exchange rings 405 is the same as that of the cooling shaft 402. The heat exchange rings 405 are made of copper. By setting the copper heat exchange rings 405 in conjunction with the heat exchange groove 406, the contact area between the cooling ring 401 and the cooling shaft 402 can be increased, thereby improving the heat exchange efficiency between the cooling ring 401 and the cooling shaft 402. The rotational cooperation between the heat exchange rings 405 and the heat exchange groove 406 can improve the stability of the cooling ring 401 rotating on the outer surface of the middle part of the cooling shaft 402.

[0039] Please see Figure 5 The first telescopic rod 10 is equipped with a first spring 11 inside. One end of the first spring 11 is located at one end of the inner wall of the telescopic outer tube of the first telescopic rod 10, and the other end of the first spring 11 is located at one end of the telescopic inner rod of the first telescopic rod 10. The first spring 11 provides elastic preload force so that the upper cooling roller 4 always applies appropriate downward pressure, which ensures that the cooling roller 4 is in full contact with the fabric for cooling while preventing excessive compression that could cause the fabric to deform.

[0040] Please see Figure 3 , Figure 4 and Figure 5 A tension roller 14 is provided between the cooling roller 4 and the traction roller group 3. The tension roller 14 is rotatably mounted on one end of the inner telescopic rod of the second telescopic rod 12 via a support frame. One end of the outer tube of the second telescopic rod 12 is fixedly connected to the side wall of the frame 1 via a support plate. A second spring 13 is provided inside the second telescopic rod 12. One end of the second spring 13 is located on one end of the inner wall of the outer telescopic tube of the second telescopic rod 12, and the other end of the second spring 13 is located on one end of the inner telescopic rod of the second telescopic rod 12. Through the synergistic action of the second telescopic rod 12 and the second spring 13, the tension roller 14 can automatically adjust its position according to the change of fabric tension, thereby keeping the fabric flat between the traction roller group 3 and the cooling roller 4. This prevents the fabric from entering between the two cooling rollers 4 in a wrinkled state, which would cause the fabric to not be able to contact the cooling rollers 4 evenly for cooling.

[0041] Please see Figure 4 , Figure 6 and Figure 7 The cooling shaft 402 is hollow in the middle, which allows the cooling shaft 402 to stably exchange heat with the cooling ring 401. This prevents the low temperature of the cooling shaft 402 from being transferred to the middle of the cooling shaft 402, which would result in excessive energy consumption. This allows the cooling shaft 402 to efficiently cool the cooling ring 401.

[0042] In this embodiment, a fabric printing and color-fixing device applied to a waterless dyeing process uses a cooling pipe 403 to cool the cooling shaft 402, which then transfers the low temperature to the cooling ring 401. This allows the cooling rings 401 of the upper and lower cooling rollers 4 to contact the upper and lower surfaces of the fabric, thereby cooling the fabric. This achieves the effect of cooling the fabric after the temperature rises due to high-temperature color fixing, preventing the fabric from softening and becoming too stretchy during winding, and allowing the winding roller 5 to wind the fabric smoothly without wrinkles appearing on the winding roller 5.

[0043] The working principle of the above embodiment is as follows: the high-temperature color-fixing mechanism 2 performs high-temperature color-fixing treatment on the fabric. The traction roller group 3 pulls the fabric and places the high-temperature color-fixed fabric between the upper and lower cooling rollers 4. The hydraulic rod 9 works, and the first telescopic rod 10, in conjunction with the first spring 11, pushes the upper cooling roller 4 downward, so that the upper cooling roller 4, in conjunction with the lower cooling roller 4, clamps the upper and lower sides of the fabric. The first telescopic rod 10, in conjunction with the first spring 11, clamps the fabric with appropriate pressure between the upper and lower cooling rollers 4, so that the cooling rollers 4 are in stable contact with the fabric. The take-up roller 5 takes up the fabric and pulls the fabric between the two cooling rollers 4. The refrigeration circulation mechanism 8 works, and the refrigeration medium is transported to the cooling pipe 403 through the water inlet pipe 6. The refrigeration medium flows in the cooling pipe 403 and cools the cooling shaft 402 through the cooling pipe 403. Shaft 402, in conjunction with heat exchange ring 405 and heat exchange groove 406, cools cooling ring 401. When take-up roller 5 takes up the fabric, the movement of the fabric causes the two cooling rings 401, which are in close contact with the fabric, to rotate on the corresponding cooling shaft 402. This allows the cooling rings 401 to stably cool the fabric passing between the two cooling rings 401, restoring the fabric's extensibility. Through the rotation of cooling rings 401, the cooler side of the cooling rings 401 is always in contact with the fabric. The refrigeration medium that has undergone heat exchange in cooling pipe 403 returns to the refrigeration circulation mechanism 8 through water outlet pipe 7 for circulating cooling. At the same time, tension roller 14, through second telescopic rod 12 and second spring 13, can stably contact the upper surface of the fabric located between cooling roller 4 and traction roller group 3, adjusting the tension of the fabric between cooling roller 4 and traction roller group 3, so that the fabric can enter the space between the two cooling rollers 4 smoothly.
