Description

Technical Field

[0001] This utility model relates to the field of textile processing technology, specifically to a dyeing and printing device for textile fabric production. Background Technology

[0002] Dyeing and printing is a crucial step in textile processing, a complex and meticulous process involving adding color, patterns, or designs to textiles, as well as improving their appearance and performance. Through continuous technological innovation and management improvements, the dyeing and printing industry can provide consumers with more diverse and high-quality textiles.

[0003] In the dyeing process, it is difficult to fully dye the fabric by directly immersing the fabric that is wrapped together in the dye. Therefore, the fabric is unfolded before being sent into the dyeing bath. However, during this process, the fabric tension may change, causing the fabric to shrink and the surface to become layered and wrinkled, which affects the dyeing quality and the smoothness of the fabric. In addition, if the fabric is not fully pre-wetted before dyeing, the dye may penetrate unevenly, affecting the dyeing quality.

[0004] For example, when printing and dyeing fabric, if the fabric is stretched out and absorbs a lot of water, it will become very heavy. At this time, it will shrink towards the center, and in severe cases, it may even shrink into a rope-like shape, which will seriously affect the absorption of dye in the central part, resulting in poor printing and dyeing effect. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a printing and dyeing device for textile production, so as to solve the technical problems that the fabric tension may change during the current printing and dyeing process, resulting in fabric shrinkage, surface layering and wrinkles, and the lack of a pre-wetting step, which affects the printing and dyeing quality.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: A printing and dyeing device for textile fabric production is designed, including a synchronizing rod and a transmission rod. Tension discs are fixedly connected to both ends of the synchronizing rod. The synchronizing rod laterally penetrates the side wall of the pumping chamber and is rotatably connected to the pumping chamber through a bearing seat. An impact disc is fixedly sleeved on the surface of the synchronizing rod inside the pumping chamber. The lower end of the side wall of the pumping chamber is fixedly connected to one end of a pumping cylinder, and the pumping cylinder communicates with the pumping chamber. One end of the transmission rod penetrates the side wall of the pumping chamber and is rotatably connected to the pumping chamber through a bearing seat. The end of the transmission rod penetrating the pumping chamber is located inside the pumping cylinder and is fixedly connected to a transmission fan blade. The other end of the transmission rod is rotatably connected to the inner side wall of the processing tank. A driving bevel gear is fixedly sleeved on the surface of the transmission rod, and the driving bevel gear meshes with a driven bevel gear. The driven bevel gear is fixedly connected to the bottom end of a vertical rod. Agitator blades are fixedly connected to the surfaces of both the vertical rod and the transmission rod.

[0007] In this design, when the No. 1 liquid pump drives clean water to circulate through the pumping cylinder to the spray pipe, the kinetic energy of the water synchronously drives the impact disc of the synchronizing rod to rotate, causing the tension discs on both sides to push the fabric to both sides. This design achieves simultaneous operation of fabric pre-wetting and tension adjustment, and also continuously unfolds the fabric surface through mechanical pushing, effectively suppressing the layering and wrinkling phenomenon caused by moisture absorption and shrinkage, and significantly improving the fabric flatness and dye penetration uniformity. At the same time, when the water flow impacts the drive fan blades and drives the drive rod to rotate, the active bevel gear drives the driven bevel gear and the vertical rod to rotate in an orthogonal direction, so that the horizontal and vertical sets of stirring blades form a composite vortex field, breaking the dye sedimentation and stratification, reducing color difference defects caused by precipitation, and greatly improving the consistency of the printed and dyed products.

[0008] Preferably, a partition is fixedly connected to the bottom inner side of the processing pool, a No. 1 bottom support roller is rotatably connected between the front and rear inner walls of the processing pool on the left side of the partition, two No. 2 bottom support rollers are rotatably connected between the front and rear inner walls of the processing pool on the right side of the partition, and top support rollers are rotatably connected to the left and right edges of the top of the processing pool.

[0009] In practical applications, the No. 1 bottom support roller immerses the fabric in water to accelerate wetting and improve the subsequent printing and dyeing effect, while the No. 2 bottom support roller makes the fabric pass parallel to the printing and dyeing area, making uniform contact with the dye and improving the efficiency of printing and dyeing.

[0010] Preferably, a spray pipe is fixedly connected between the front and rear inner walls of the processing pool above the No. 1 bottom support roller. The two ends of the spray pipe are respectively connected to one end of the water inlet pipe on the front and rear outer walls of the processing pool, and the other ends of the two water inlet pipes are respectively connected to the front and rear ends of the pumping chamber.

[0011] In practical applications, the surface of the spray pipe is equipped with several nozzles to spray the passing fabric evenly, pre-wetting the fabric and facilitating the entry of dye into the gaps between the fabric fibers.

[0012] Preferably, the other end of the pumping cylinder is connected to the outlet of the No. 1 liquid pump, the inlet of the No. 1 liquid pump is connected to one end of the connecting pipe, the other end of the connecting pipe passes through the surface of the partition and is located on the left side of the partition, and an isolation chamber is fixedly connected to the bottom of the processing pool outside the No. 1 liquid pump, and the pumping cylinder passes through the side wall of the isolation chamber.

[0013] In practical applications, the No. 1 liquid pump draws away the clean water on the left side of the partition, and returns to the left side of the partition after one cycle, thus circulating the clean water and reducing the waste of water resources; the isolation chamber can isolate the dye water from the No. 1 liquid pump.

[0014] Preferably, four spray pipes are fixedly connected to the top of the processing pool above the pumping tank. The four spray pipes are connected to the outlet end of the pumping pipe, and the other end of the pumping pipe is connected to the outlet of the second pump. The inlet of the second pump is connected to the interior of the processing pool through a section of pipe.

[0015] In practical applications, the No. 2 liquid pump extracts the dye from the processing tank and flows it out through the spray pipe, thus performing a circulation operation. After a period of time, the amount of dye decreases, at which point the dye can be replenished in the processing tank, thereby ensuring the continuous operation of printing and dyeing.

[0016] Preferably, the vertical rod passes through the surface of the support frame and is rotatably connected to the support frame through a bearing seat, and the support frame is fixedly connected to the inner bottom surface of the processing pool.

[0017] In practical applications, the vertical rod rotates, driving the stirring blades to rotate, which in turn works with the stirring blades on the transmission rod to stir the dye, making the dye mixture more uniform and improving the consistency of the printed and dyed products.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This utility model constructs a linked pre-wetting system, mechanically coupling the spray pipe, water pumping chamber, and tension disc. When the No. 1 liquid pump drives clean water to circulate through the pumping cylinder to the spray pipe, the kinetic energy of the water synchronously drives the impact disc of the synchronizing rod to rotate, causing the tension discs on both sides to push the fabric to both sides. This design achieves simultaneous operation of fabric pre-wetting and tension adjustment, and also continuously unfolds the fabric surface through mechanical pushing, effectively suppressing the layering and wrinkling phenomenon caused by moisture absorption and shrinkage. Compared with the traditional step-by-step pre-wetting and tension control process, this solution achieves functional integration through fluid kinetic energy transfer, significantly improving the fabric flatness and dye penetration uniformity.

[0020] 2. This utility model employs a transmission structure of a transmission rod and a vertical rod, converting the fluid kinetic energy of the pumping system into bidirectional stirring power. When the water flow impacts the transmission fan blades, driving the transmission rod to rotate, the active bevel gear drives the driven bevel gear and the vertical rod to rotate in an orthogonal direction, causing the horizontal and vertical sets of stirring blades to form a composite vortex field. This structure overcomes the limitations of the traditional single stirring mode, breaking up dye sedimentation and stratification through three-dimensional turbulence, ensuring highly homogeneous dye liquor concentration and temperature distribution, reducing color difference defects caused by sedimentation, and significantly improving the consistency of printed and dyed products.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] Example 1: A dyeing and printing apparatus for textile fabric production, see [link to example]. Figures 1 to 3A textile fabric printing and dyeing device includes a synchronizing rod 5 and a transmission rod 7. Tension discs 6 are fixedly connected to both ends of the synchronizing rod 5. The synchronizing rod 5 transversely penetrates the side wall of a water pumping chamber 4 and is rotatably connected to the water pumping chamber 4 via a bearing seat. The outer surface of the synchronizing rod 5 is fixedly connected to the inner ring of the bearing seat, and the outer ring of the bearing seat is fixedly connected to the inner wall of the water pumping chamber 4. To prevent water from leaking out of the water pumping chamber 4 from the bearing seat, a water-proof bearing seat is selected. The surface of the synchronizing rod 5 inside the water pumping chamber 4 is fixed... An impact disc 501 is fitted onto the surface of the processing tank 1. The surface of the impact disc 501 has several grooves arranged in a circular array. When impacted by water flow, the grooves rotate due to the inertia of the water flow, thereby causing the external tension disc 6 to rotate. A spray pipe 402 is fixedly connected between the front and rear inner walls of the processing tank 1 above the first bottom support roller 201. Both ends of the spray pipe 402 are connected to one end of the water inlet pipe 401 on the front and rear outer walls of the processing tank 1, respectively. The other ends of the two water inlet pipes 401 are connected to the front and rear of the pumping chamber 4, respectively. Both ends are connected; in order to pre-wet the fabric before printing and dyeing, the fabric will first pass under the first bottom support roller 201, and clean water will be added in advance inside the processing pool 1 on the left side of the partition 101, together with the spray pipe 402 above, to pre-wet the fabric; during this process, the first liquid pump 3 is started, pumping clean water to move in the order of water pumping cylinder 302, water pumping chamber 4, and water inlet pipe 401, and finally reach the spray pipe 402. The surface of the spray pipe 402 is equipped with several nozzles, which are directed at the fabric below. Pre-wetting treatment is performed by spraying. During the spraying process, as water flows through the pumping chamber 4 and passes through the impact plate 501 of the synchronizing rod 5, the impact of the water flow drives the impact plate 501 to rotate, which in turn drives the tension plates 6 at both ends of the synchronizing rod 5 to rotate. As the tension plates 6 rotate, they agitate the fabric above, causing the fabric to spread out to both sides. This avoids the problem of the fabric shrinking too much due to tension during the printing and dyeing process, which would lead to poor printing and dyeing results. Thus, pre-wetting and agitation of the fabric are achieved simultaneously, improving the quality of printing and dyeing.

[0027] For details, see Figure 1 and Figure 2The lower end of the side wall of the pumping tank 4 is fixedly connected to one end of the pumping cylinder 302, and the pumping cylinder 302 is connected to the pumping tank 4. The other end of the pumping cylinder 302 is connected to the outlet of the first liquid pump 3. The inlet of the first liquid pump 3 is connected to one end of the connecting pipe 303. The other end of the connecting pipe 303 penetrates the surface of the partition 101 and is located on the left side of the partition 101. An isolation chamber 301 is fixedly connected to the bottom of the processing pool 1 outside the first liquid pump 3. The pumping cylinder 302 penetrates the side wall of the isolation chamber 301. The first liquid pump 3 is set in the isolation chamber 301, thereby avoiding The dye water in processing pool 1 affects the No. 1 liquid pump 3. The No. 1 liquid pump 3 draws water from the processing pool 1 on the left side of partition 101 and pumps the water through the pump cylinder 302 into the pumping chamber 4. After circulating once, the water returns to the processing pool 1 on the left side of partition 101, thereby reducing the waste of water resources. After a period of use, the circulating water can be drained through the drain outlet opened on the side wall of processing pool 1, and then new water can be added. When adding water, ensure that the water level is higher than the No. 1 bottom support roller 201, so as to immerse and pre-wet the fabric.

[0028] Furthermore, such as Figure 1 and Figure 2 As shown, a partition 101 is fixedly connected to the bottom inner side of the processing pool 1. A first bottom support roller 201 is rotatably connected between the front and rear inner walls of the processing pool 1 on the left side of the partition 101. Two second bottom support rollers 202 are rotatably connected between the front and rear inner walls of the processing pool 1 on the right side of the partition 101. Top support rollers 2 are rotatably connected to the left and right edges of the top of the processing pool 1. The fabric passes through the top support roller 2 on the left side first, then enters the processing pool 1 downwards, passes over the first bottom support roller 201 and the top surface of the partition 101, then goes downwards again, passes under the two second bottom support rollers 202, and finally leaves the top support roller 2 on the right side. In this state, the fabric is pre-wetted, stretched, and dyed. It should be noted that the two second bottom support rollers... Since the heights of rollers 202 and 202 are consistent, the fabric passing between the two bottom support rollers 202 will pass parallel to each other, thus receiving the dye water sprayed from the upper spray pipe 14 evenly. It should be noted that the bottom of the bottom support roller 202 and the top of the tension plate 6 are at the same level, thus ensuring that the tension plate 6 will neither push up the passing fabric nor lose its ability to move the fabric because it is lower than the bottom support roller 202. The tension plate 6 will contact the bottom of the fabric, thus maintaining continuous movement to both sides. In addition, the dye liquid level in the processing pool 1 will be lower than the tension plate 6 to avoid affecting the rotation of the tension plate 6. At the same time, the surface of the tension plate 6 is very smooth, with little friction after contact with the fabric, which facilitates continuous rotation and prevents it from sticking to the fabric.

[0029] It should be noted that this device is mainly designed for the pre-wetting and tension issues of the fabric. The top support roller 2, bottom support roller 1 201 and bottom support roller 202 through which the fabric passes do not have a drive structure. Therefore, the end of the fabric that leaves the processing pool 1 through bottom support roller 202 will be connected to the receiving roller with motor drive. The external receiving roller pulls the fabric forward, so there is no need to worry about the fabric passing through.

[0030] It is worth noting that, see Figure 1 and Figure 3 Four liquid-spraying pipes 14 are fixedly connected to the top of the processing pool 1 above the pumping tank 4. The four liquid-spraying pipes 14 are connected to the outlet end of the pumping pipe 13. The other end of the pumping pipe 13 is connected to the outlet of the second liquid pump 12. The inlet of the second liquid pump 12 is connected to the inside of the processing pool 1 through a section of pipe. After the second liquid pump 12 is started, it draws the dye water inside the processing pool 1 on the right side of the partition 101, rises along the pumping pipe 13, carries it to the liquid-spraying pipe 14, and flows out along the liquid-spraying outlets evenly opened at the bottom of the liquid-spraying pipe 14, thereby performing printing and dyeing operations on the surface of the fabric below.

[0031] Specifically, such as Figure 2 and Figure 3 As shown, one end of the transmission rod 7 penetrates the side wall of the pumping chamber 4 and is rotatably connected to the pumping chamber 4 through a bearing seat. The outer surface of the transmission rod 7 is fixedly connected to the inner ring of the bearing seat, and the outer ring of the bearing seat is fixedly connected to the inner wall of the pumping chamber 4. One end of the transmission rod 7 penetrating the pumping chamber 4 is located inside the pumping cylinder 302 and is fixedly connected to a transmission fan blade 701. The other end of the transmission rod 7 is rotatably connected to the inner side wall of the processing pool 1. A driving bevel gear 8 is fixedly sleeved on the surface of the transmission rod 7. The driving bevel gear 8 meshes with a driven bevel gear 9. The driven bevel gear 9 is fixedly connected to the bottom end of the vertical rod 11. Agitator blades 111 are fixedly connected to the surfaces of both the vertical rod 11 and the transmission rod 7. When the first... When the liquid pump 3 pumps water, the water flows through the pumping cylinder 302 into the pumping chamber 4. During this process, the water flow impacts the agitator blades 111 on the transmission rod 7, causing the transmission rod 7 to rotate. As the transmission rod 7 rotates, it drives the agitator blades 111 on its surface to rotate, which in turn drives the active bevel gear 8 to rotate. The active bevel gear 8 then drives the driven bevel gear 9 and the vertical rod 11 to rotate. The vertical rod 11 is also equipped with agitator blades 111 on its surface. The agitator blades 111 in both the horizontal and vertical directions rotate together, thereby agitating the dye water in the processing tank 1, reducing dye sedimentation, making the dye and water mix more thoroughly, and improving the dyeing effect.

[0032] It is worth mentioning that the vertical rod 11 passes through the surface of the support frame 10 and is rotatably connected to the support frame 10 through the bearing seat. The outer surface of the vertical rod 11 is fixedly connected to the inner ring of the bearing seat, and the outer ring of the bearing seat is fixedly connected to the inner wall of the support frame 10. The support frame 10 is fixedly connected to the inner bottom surface of the processing pool 1. The vertical rod 11 is located below the liquid surface of the processing pool 1. Its bearing seat meets the requirements for use under the liquid surface, such as an oil-free underwater bearing seat. Its interior uses self-lubricating materials, such as polytetrafluoroethylene (PTFE), etc., which do not require external lubrication. The material has good corrosion resistance and is suitable for underwater environments. Due to its self-lubricating and corrosion-resistant properties, maintenance requirements are reduced.

[0033] It should be noted that since the transmission rod 7 is also located below the liquid surface of the processing tank 1 and passes through the pumping chamber 4, which contains clean water while the processing tank 1 contains dye water, it is necessary to ensure waterproofing and sealing at the penetration point. Therefore, a waterproof bearing housing, such as a stainless steel waterproof bearing housing, must be selected. This type of bearing has a sealing ring between the inner and outer rings. The inner side of the sealing ring is a groove shape, and a spring clamp is fitted on the groove wall near the inner ring of the bearing. This design provides a strong seal, reliable waterproofing, dustproofing, and oil retention, thus preventing the dye water from the processing tank 1 from entering the pumping chamber 4 while ensuring the normal rotation of the transmission rod 7.

[0034] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
