Description

Technical Field

[0001] This application relates to the technical field of dyeing devices for textile printing and dyeing, and particularly relates to a dyeing device for textile printing and dyeing and its dyeing process. Background Art

[0002] According to market demand, some fabrics need to be dyed before being made into products, and the quality of dyeing directly determines the value of the products. There are many reasons for uneven dyeing of fabrics. Among them, the hydrophobicity of some fabric materials and the weaving process of the fabric itself will cause a large surface tension of water on the fabric, resulting in the dyeing solution being unable to quickly and completely penetrate into the fabric interior, causing uneven dyeing.

[0003] When the weaving process of the fabric consists of multiple fiber bundles, many fine fibers will adhere to the fabric surface, and these fine fibers will form a fiber mesh that is difficult to distinguish with the naked eye. This fiber mesh has a certain blocking effect on water, and thus it is easy to cause uneven dyeing of the fabric during dyeing.

[0004] Existing fabric dyeing equipment lacks an external force assisting mechanism to destroy the water-blocking structure of the fiber mesh layer on the fabric surface, accelerating the entry of the dyeing solution into the fabric interior, resulting in the problem that the dyeing solution cannot quickly enter the fabric interior due to the excessive surface tension of water on the fabric surface, and thus it is easy to appear uneven dyeing. Summary of the Invention

[0005] This application proposes a dyeing device for textile printing and dyeing and its dyeing process, which has the advantages of destroying the fiber mesh layer formed by a large number of fibers on the fabric surface by means of external force, reducing the surface tension of the dyeing solution on the fabric surface, accelerating the speed of the dyeing solution entering the fabric interior, and at the same time, under the continuous up-and-down push of the impact plate, the dyeing components in the dyeing solution at the impact plate will accelerate the combination with the fabric under the thrust and enter the deeper layer of the fabric faster, thereby achieving the effect of uniform dyeing of the fabric inside and outside and increasing the dyeing rate, so as to solve the problem that existing fabric dyeing equipment lacks an external force assisting mechanism to destroy the water-blocking structure of the fiber mesh layer on the fabric surface, accelerating the entry of the dyeing solution into the fabric interior, resulting in the problem that the dyeing solution cannot quickly enter the fabric interior due to the excessive surface tension of water on the fabric surface, and thus it is easy to appear uneven dyeing.

[0006] To achieve the above object, the present application adopts the following technical solution: A dyeing device for textile printing and dyeing, comprising a dyeing tank, a rotating roller, and an auxiliary component. Strip-shaped through grooves for the entry and exit of fabrics are provided at both ends of the dyeing tank. Two positioning rollers are symmetrically installed inside the dyeing tank, and an adjusting roller is arranged between the two positioning rollers. The rotating roller is sleeved and connected to the positioning roller and is rotatably connected to the positioning roller. A plurality of annularly distributed first magnetic strips are embedded on the rotating roller. Below the rotating roller, an impact plate and a support frame adapted to the bottom contour of the rotating roller are sequentially arranged, and the support frame is fixedly connected to the inner wall of the dyeing tank. On the side of the impact plate facing the rotating roller, a second magnetic strip with the opposite magnetism to the first magnetic strip is embedded. At the bottom of both ends of the impact plate, positioning shafts are fixedly connected. The bottom ends of the two positioning shafts jointly penetrate the support frame and are slidably connected to the support frame. The auxiliary component is installed on the side of the impact plate facing the rotating roller and is used to assist the impact plate in destroying the water-blocking structure of the fabric surface fibers.

[0007] Further, there are four auxiliary components, which are respectively arranged on the upper surfaces of both ends of the two impact plates. The auxiliary component includes two positioning grooves respectively opened at the top of both ends of the impact plate and a scraper for pre-scraping the fluff and impurities on the fabric surface. The scraper is rotatably connected in the positioning groove. A plurality of first springs for enhancing elastic auxiliary reset are fixedly installed on the opposite side of the scraper and the positioning groove. A plurality of hemispherical blocks for destroying the water-blocking layer structure of the fabric surface are arranged in an array on the first spring.

[0008] Further, two second springs are fixedly connected between the upper surfaces of both ends of the support frame and the bottom of the second spring.

[0009] Further, a threaded shaft is fixedly connected to the bottom of the support frame. The bottom end of the threaded shaft penetrates the support frame and is threadedly connected to a threaded sleeve. The bottom end of the threaded sleeve is rotatably connected to a fixing ring, and the fixing ring is fixedly connected to the bottom of the dyeing tank. A plurality of stirring shafts for stirring the dyeing agent precipitate at the bottom of the dyeing tank are annularly distributed on the arc-shaped outer wall of the threaded shaft.

[0010] Further, a plurality of diversion holes are provided on the support frame, and the plurality of diversion holes are symmetrically arranged on both sides of the second magnetic strip respectively. A limiting frame is fixedly connected in each diversion hole. Two adapted rotating pieces are attached to the upper surface of the limiting frame, and both rotating pieces are rotatably connected to the inner wall of the diversion hole. Two symmetrically arranged diversion grooves are respectively opened on the support frame corresponding to the plurality of diversion holes.

[0011] Further, the shapes of both sides of the stirring shaft are set to be triangular, and the adjacent sides of the two rotating pieces are both set to be matching inclined surfaces.

[0012] Further, the adjusting roller includes a first connecting rod and a second connecting rod, and the first connecting rod is threadedly connected to the second connecting rod. A plurality of clamping grooves adapted to the ends of the first connecting rod and the second connecting rod are formed on both sides of the inner wall of the dyeing tank, and the plurality of clamping grooves are vertically distributed. An anti-slip nut and a gasket adapted thereto are respectively installed between the first connecting rod and the second connecting rod.

[0013] Further, the bottom of the dyeing tank corresponding to the two support frames is provided with an inclined groove recessed downward, and two symmetrically arranged guide shafts are arranged in the strip-shaped through groove.

[0014] Further, limiting rings are fixedly connected to both ends of the rotating roller, and the circumference of the limiting ring is greater than the circumference of the end of the rotating roller.

[0015] Further, a dyeing process for a dyeing device for textile printing and dyeing includes the following steps:

[0016] S1. Pass one of the strip-shaped through grooves of the fabric through, then pass through the bottoms of the two rotating rollers and the top of the adjusting roller as required, and finally pass out from the other strip-shaped through groove;

[0017] S2. Check whether both ends of the fabric are stably connected to the external feeding device and the coiling device;

[0018] S3. Pour the evenly stirred dyeing solution into the dyeing tank;

[0019] S4. Use an external temperature control device to heat and control the temperature of the dyeing solution in the dyeing tank;

[0020] S5. Start the external feeding device and the coiling device to uniformly dye the fabric.

[0021] The beneficial effects of the present invention are as follows:

[0022] A dyeing device for textile printing and dyeing provided by the present application drives a rotating roller to rotate through the frictional force between the fabric and the rotating roller. At this time, a plurality of first magnetic strips embedded on its outer surface, when annularly distributed, will sequentially and orderly attract the second magnetic strips embedded correspondingly on the impact plate directly below. Since the magnetic properties of the first magnetic strip and the second magnetic strip are opposite, when in the relative position, the attraction between the two is the greatest. At this time, under the action of the magnetic attraction, the second magnetic strip will drive the impact plate to move upward and stretch the second spring fixedly connected between the support frame and the impact plate. During this period, under the action of the magnetic attraction between the first magnetic strip and the second magnetic strip, the gravity of the impact plate itself, and the tensile force of the second spring, the impact plate will perform reciprocating up and down movements and stably impact the fabric wound around the bottom of the rotating roller. On the one hand, it can use external force to destroy the fiber mesh layer formed by a large number of fibers on the fabric surface, reduce the surface tension of the dyeing solution on the fabric surface, and accelerate the speed of the dyeing solution entering the fabric interior. On the other hand, under the continuous up and down pushing of the impact plate, the dyeing components in the dyeing solution at the impact plate will accelerate the combination with the fabric under the thrust and enter the deeper layer of the fabric faster, thereby achieving the effect of uniformly dyeing the fabric inside and outside. Compared with the traditional dyeing equipment where the fabric simply moves between multiple fixed rollers, lacking the destruction intervention of external force on the water-blocking structure formed by the fibers on the fabric surface, the fabric needs to be soaked in the dyeing equipment for a longer time, not only the uniform dyeing effect cannot be guaranteed, but also the dyeing efficiency is relatively slow. This setting can utilize the power during the transmission of the fabric itself and related structures to destroy the water-blocking layer structure formed by a large number of fibers on the fabric surface, solve the problem that the dyeing solution cannot quickly enter the fabric interior, and cause uneven dyeing of the fabric.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1

[0035] As Figures 1-8As shown in the figure, when the fabric is wound by an external coiling device, the fabric located in the dyeing tank 1 will move in and out between the two strip-shaped through grooves and the corresponding guide shafts 20. During this period, the fabric will pass through the bottom of the two rotating rollers 4 immersed in the dyeing solution and the top of the adjusting roller 3 between the two rotating rollers 4, forming a relatively stable three-point limit. This enables the fabric to maintain a stable movement when passing through the dyeing solution. During the movement of the fabric, the rotating roller 4 rotatably connected to the positioning roller 2 will be driven by the fabric due to the frictional force generated by the close fit between the rotating roller 4 and the fabric, and thus rotate on the positioning roller 2. Compared with the traditional fixed roller shaft, this setting can reduce the frictional resistance and wear of the fabric during movement and improve the dyeing efficiency. During the rotation of the rotating roller 4, a plurality of first magnetic strips 5 embedded on its outer surface will sequentially and orderly attract the second magnetic strips 8 embedded on the corresponding impact plates 7 directly below in a circular distribution. Since the magnetic properties of the first magnetic strips 5 and the second magnetic strips 8 are opposite, when they are in a relative position, the attraction force between the two is the largest. At this time, under the action of the magnetic attraction force, the second magnetic strip 8 will drive the impact plate 7 to move upward and stretch the second spring 11 fixedly connected between the support frame 6 and the impact plate 7. During this period, the two positioning shafts 9 fixedly connected to the bottom of the support frame 6 will provide stable limit and guidance for the impact plate 7 when passing through the support frame 6 and being slidably connected, enabling the impact plate 7 to maintain a stable up-and-down movement. Under the action of the magnetic attraction force of the first magnetic strips 5 and the second magnetic strips 8, the gravity of the impact plate 7 itself, and the pulling force of the second spring 11, the impact plate 7 will perform a reciprocating up-and-down movement and impact the fabric wound around the bottom of the rotating roller 4 stably. On the one hand, it can use external force to break the fiber mesh layer formed by a large number of fibers on the fabric surface, reduce the surface tension of the dyeing solution on the fabric surface, and accelerate the speed of the dyeing solution entering the fabric interior. On the other hand, under the continuous up-and-down pushing of the impact plate 7, the dyeing components in the dyeing solution at the impact plate 7 will accelerate the combination with the fabric under the thrust and enter the deeper layer of the fabric faster, thereby achieving the effect of uniform dyeing of the fabric inside and outside. Compared with the traditional dyeing equipment where the fabric simply moves between multiple fixed rollers, there is a lack of external force to interfere with the destruction of the water-blocking structure formed by the fabric surface fibers, resulting in a longer soaking time required for the fabric in the dyeing equipment. Not only can the uniform dyeing effect not be guaranteed, but the dyeing efficiency is also relatively slow.

[0036] Regarding the power setting method for driving the impact plate 7 to move up and down by the first magnetic strip 5 and the second magnetic strip 8, the following method can also be adopted:

[0037] Fix a single first magnetic strip 5 fixedly embedded at the bottom end of the positioning roller 2. The first magnetic strip 5 is arranged corresponding to the second magnetic strip 8. An anti-magnetic strip is arranged in an annular array on the outer periphery of the rotating roller 4. The anti-magnetic strip can be made of anti-magnetic materials (such as silicon steel, permalloy, etc.). When the anti-magnetic strip rotates between the first magnetic strip 5 and the second magnetic strip 8, it produces an anti-magnetic effect on the magnetic attraction force between the first magnetic strip 5 and the second magnetic strip 8, so that the magnetic attraction force is briefly shielded, and thus the impact plate 7 is reset under the pulling force of the second spring 11, and then moves up and down.

[0038] Embodiment 2

[0039] On the basis of Embodiment 1, further improvements are made, such as Figure 7 As shown, by using the scraper 101 and the first spring 102 in the auxiliary mechanism 10, when the impact plate 7 continuously impacts the bottom of the rotating roller 4 indirectly upward to cloth, the scraper 101 rotatably connected in the top positioning grooves 104 at both ends will contact the cloth surface in advance due to the support of the first spring 102 and its own inclination angle, and keep abutting against the cloth surface during the continuous upward movement of the impact plate 7, and continuously squeeze and slide. During this process, impurities such as fluff and dust attached to the cloth surface will be scraped off during the squeezing and sliding between the scraper 101 and the cloth surface, effectively avoiding the problem that impurities such as fluff and dust adhere to the cloth surface and affect the penetration of the dyeing solution, resulting in uneven dyeing. During this period, the first spring 102 is adaptively deformed during extrusion, providing a stable abutting effect for the scraper 101 with cloth at different conveying angles. In addition, the multiple hemispherical blocks 103 on the surface of the scraper 101 will also damage the water-blocking layer structure composed of a large number of fibers on the cloth surface, guiding and accelerating the water flow into the cloth interior. It can achieve scraping off impurities on the cloth in advance and damaging the fiber water-blocking layer on the cloth surface before the impact plate 7 completely impacts the cloth, thereby assisting the impact of the impact plate 7 and accelerating the rapid entry of the dyeing solution into the cloth to complete uniform dyeing.

[0040] Embodiment 3

[0041] On the basis of Embodiment 2, further improvements are made, such as Figures 4-5 As shown, when the impact plate 7 moves up and down reciprocally, the threaded shaft 12 fixedly connected to its bottom will penetrate through the support frame 6 and rotate with the threaded sleeve 13 and the fixed ring 14, and on the basis that the fixed ring 14 is fixedly connected to the bottom inner wall of the dyeing tank 1, drive the threaded shaft 12 to rotate. At this time, the multiple stirring shafts 15 fixedly connected to the outer surface of the threaded shaft 12 will stir the dyeing components precipitated at the bottom inner wall of the dyeing tank 1 and roll them up and redistribute them throughout the dyeing tank 1, and the cloth near the bottom of the dyeing tank 1 will obtain a more sufficient dyeing effect, as well as improve the uniformity effect of the dyeing solution in the dyeing tank 1.

[0042] Meanwhile, during the up-and-down reciprocating motion of the impact plate 7, the water pressure difference generated by its up-and-down motion can guide the dyeing solution to pass through a plurality of diversion holes 16 formed in the impact plate 7, directly surging and impacting the surface of the fabric wound around the bottom of the rotating roller 4. Among them, the two diversion grooves 19 formed in the support frame 6 can reduce the interception and shielding effect on the dyeing solution, enabling the dyeing components in the solution to directly and quickly enter between the impact plate 7 and the rotating roller 4 through the plurality of diversion holes 16 to dye the fabric, improving the dyeing effect. When the impact plate 7 descends, when the dyeing solution enters the diversion holes 16 under the action of pressure, the impact force of the water flow will cause the two rotating pieces 18 rotatably connected in the diversion holes 16 to open upward, thus ensuring the flow of water. On the contrary, during the ascending process of the impact plate 7, due to the fitting connection between the upper surface of the limit frame 17 and the rotating piece 18, the two rotating pieces 18 remain in a stable closed state. At this time, the dyeing components of the dyeing solution flowing between the rotating roller 4 and the impact plate 7 will be pushed by the impact plate 7 and the closed rotating pieces 18 to impact the surface of the fabric between the rotating roller 4 and the impact plate 7, thereby accelerating the entry of the dyeing components into the fabric interior and greatly improving the dyeing effect of the fabric.

[0043] In addition, the shapes on both sides of the stirring shaft 15 are set to be triangular, which can reduce the resistance between it and the solution during the stirring of the stirring shaft 15, ensuring that the threaded sleeve 13 can rotate stably. And the adjacent sides of the two rotating pieces 18 are set to be matching inclined surfaces, which can reduce the downward overflow of the water flow when the rotating pieces 18 push the water flow of the solution to rise, providing a better sealing effect and ensuring that the water flow can more powerfully surge and impact the surface of the fabric, promoting the dyeing effect of the fabric. Also, the bottom of the dyeing tank 1 corresponding to the two support frames 6 is set to be an inclined surface groove that is concave downward, which is also to accelerate the precipitation of the dyeing components to gather together, facilitating the stirring shaft 15 to re-roll them during stirring and accelerating their better distribution in the solution.

[0044] Example Four

[0045] On the basis of Example One, further supplements are made, such as Figures 1-8As shown, before fabric dyeing, according to the fabric material and actual requirements, the position of the adjusting roller 3 in the vertical direction can be freely adjusted through a plurality of slots vertically opened on both sides of the inner wall of the dyeing tank 1, so as to change the tension of the fabric on the two rotating rollers 4 and provide a better dyeing effect. When removing and installing the adjusting roller 3, only need to first twist the anti-loosening nut to loosen it, and then rotate the first connecting rod 301 and the second connecting rod 302 to control the distance between them to become larger or smaller, completing the removal and installation of the adjusting roller 3 in the slot. After both ends of the adjusting roller 3 are completely inserted into the corresponding two slots, twist the anti-loosening nut again. With the cooperation of the anti-loosening nut and the gasket, the stability of the first connecting rod 301 and the second connecting rod 302 in the slot can be further improved, thereby enhancing the stability effect when the fabric moves on the adjusting roller 3 and ensuring a stable dyeing process for the fabric.

[0046] In addition, the limiting rings 21 fixedly connected to both ends of the rotating roller 4 can prevent the fabric from shifting out of the range of the rotating roller 4, ensuring that the fabric can be stably conveyed on the two rotating rollers 4.

[0047] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
