[0002] A dyeing tank is a piece of equipment used in the textile dyeing process, mainly used to store and process dyeing liquid (dyes and auxiliaries) so that textiles (such as cloth, yarn, etc.) can be immersed in it for dyeing. Dyeing tanks are usually made of stainless steel or other corrosion-resistant materials to ensure that they can withstand the various chemicals and high temperatures that may be used in the dyeing process.

[0003] The patent document with application number 201921142269.8 discloses a new type of fabric printing and dyeing tank mechanism in a fabric printing and dyeing production line, including a tank body, a heating tube is provided at the inner bottom end of the tank body, a stirring shaft is opened in the middle of the tank body, a stirring rod is fixedly connected to the circumference of the stirring shaft, a stirring motor is provided on the outer side of the tank body, a support seat is fixedly connected to the bottom end of the stirring motor, the support seat is fixedly connected to the tank body, and one end of the stirring shaft passes through the tank body and is fixedly connected to the shaft on the stirring motor.

[0004] However, in traditional printing and dyeing tanks used for fabric processing, the temperature distribution in the printing and dyeing tanks may be uneven in winter or when the temperature is low, resulting in different degrees of dye dissolution and aggregation in different areas. Some dyes may be deposited at the bottom or side walls of the tank to form a thicker dye layer. When the fabric enters the tank through the feed port, if it comes into contact with these deposits, it may cause obvious dye marks or spots on the fabric, and even local over-dyeing or under-dyeing may occur, which will directly affect the printing and dyeing quality of the product. Utility Model Content

[0005] The utility model discloses a printing and dyeing tank structure for cloth processing, aiming to solve the technical problem that in a traditional printing and dyeing tank for cloth processing, the temperature distribution in the printing and dyeing tank may be uneven in winter or when the temperature is low, resulting in different degrees of dissolution and aggregation of dyes in different areas, and part of the dyes may be deposited at the bottom or side wall of the tank to form a thicker dye layer. When the cloth enters the tank through a feed inlet, if it contacts these deposits, it may leave obvious dye marks or spots on the cloth, and even may cause local over-dyeing or under-dyeing, which will directly affect the printing and dyeing quality of the product.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

The water pump draws the dye inside the printing and dyeing tank body through the installation pipe, and then transports it to the connection box through the connecting pipe. By arranging eight symmetrically distributed nozzles on the bottom outer wall of the connection box, the dye can be evenly sprayed on the upper surface of the fabric body. When used in conjunction with the moving mechanism, the dye can cover the surface of the fabric body. Before the fabric body enters the printing and dyeing tank body or after the fabric body is dyed, the fabric body can be pre-colored and supplemented.

The valve design on the mounting tube allows the operator to easily control the flow of the dye. When it is necessary to stop dyeing or adjust the dye flow, it is only necessary to close or adjust the valve. The operation is simple and quick. The device can achieve simultaneous stirring and heating of the dye, thereby improving the solubility and uniformity of the dye, helping to improve the printing and dyeing efficiency and quality, and avoiding adverse effects of excessively high or low temperatures on the dye.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0027] The utility model discloses a printing and dyeing tank structure for cloth processing, which is mainly applied to traditional printing and dyeing tanks for cloth processing in winter or when the temperature is low. The temperature distribution in the printing and dyeing tank may be uneven, resulting in different degrees of dissolution and aggregation of dyes in different areas. Part of the dye may be deposited at the bottom or side wall of the tank to form a thicker dye layer. When the cloth enters the tank through the feed port, if it comes into contact with these deposits, it may cause obvious dye marks or spots on the cloth, and even local over-dyeing or under-dyeing may occur, which will directly affect the printing and dyeing quality of the product.

[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A printing and dyeing tank structure for cloth processing includes a printing and dyeing tank body 2 and a cloth body 13, a support frame 1 is provided on the bottom outer wall of the printing and dyeing tank body 2, and also includes:

[0029] Stirring mechanism: located inside the printing and dyeing tank body 2;

[0030] Auxiliary dyeing mechanism: located at the top of the printing and dyeing tank body 2, the auxiliary dyeing mechanism includes a fixed box 11 and a mounting rod 18, the top outer wall of the fixed box 11 is provided with a limited position opening, one end of the mounting rod 18 is provided with a connecting box 8, the bottom outer wall of the connecting box 8 is provided with eight symmetrically distributed nozzles 12, the outer walls of both sides of the printing and dyeing tank body 2 are provided with a water pump, the top of the water pump is provided with a connecting pipe 9, one end of the connecting pipe 9 is communicated with the interior of the connecting box 8, the bottom of the water pump is provided with a mounting pipe 10, one end of the mounting pipe 10 is communicated with the interior of the printing and dyeing tank body 2, and a valve is provided on the circumferential inner wall of the mounting pipe 10;

[0031] Moving mechanism: located directly below the auxiliary dyeing mechanism.

[0032] The nozzle 12 is a trumpet-shaped structure, which makes it easier for the dye to cover the target area more evenly, achieve a better spraying effect, and better assist in coloring the fabric body 13.

[0033] During the specific implementation process, the top outer wall of the printing and dyeing tank body 2 is provided with a first mounting frame 4 and a second mounting frame 5, the outer wall on the opposite side of the second mounting frame 5 is provided with a feed roller, and the outer wall on the opposite side of the first mounting frame 4 is provided with a pressure roller. The feed roller on the second mounting frame 5 can efficiently and stably transport the fabric body 13 into the printing and dyeing tank body 2, ensuring that the fabric body 13 can continuously and smoothly enter the interior of the printing and dyeing tank body 2. The pressure roller on the first mounting frame 4 applies a certain pressure to the fabric body 13 after it is dyed, which helps the fabric body 13 to better contact with the dye during the printing and dyeing process, thereby improving the uniformity and quality of printing and dyeing.

[0034] Specifically, when in use, the dye inside the printing and dyeing tank body 2 is first heated and fully stirred by the stirring mechanism, and then the valve in the installation pipe 10 is opened, and the water pump is turned on at the same time. The water pump draws out the dye inside the printing and dyeing tank body 2 through the installation pipe 10, and then transports it to the connection box 8 through the connecting pipe 9. By arranging eight symmetrically distributed nozzles 12 on the bottom outer wall of the connection box 8, the dye can be evenly sprayed on the upper surface of the fabric body 13. When used in conjunction with the moving mechanism, the dye can cover the surface of the fabric body 13. Before the fabric body 13 enters the printing and dyeing tank body 2 or after the fabric body 13 is dyed, the fabric body 13 can be sprayed evenly. The body 13 is pre-colored and supplemented with color, and then the excess dye is squeezed out by the pressure roller. The excess dye will drip back into the interior of the printing and dyeing tank body 2, so that the cloth body 13 is better in contact with the dye during the printing and dyeing process, thereby improving the uniformity and quality of printing and dyeing. The valve design on the mounting tube 10 allows the operator to easily control the flow of the dye. When it is necessary to stop dyeing or adjust the dye flow, it is only necessary to close or adjust the valve. The operation is simple and quick. The device can achieve simultaneous stirring and heating of the dye, thereby improving the solubility and uniformity of the dye, helping to improve the printing and dyeing efficiency and quality, and avoiding adverse effects of excessively high or low temperatures on the dye.

[0035] Reference Figure 2 and Figure 5 In a preferred embodiment, the stirring mechanism includes a mounting plate, which is mounted on one side of the printing and dyeing tank body 2. A first motor 3 is provided on one side of the mounting plate. The output shaft of the first motor 3 is fixedly connected to a stirring rod 14. One end of the stirring rod 14 passes through an outer wall of one side of the printing and dyeing tank body 2, and one end of the stirring rod 14 is connected to an inner wall of one side of the printing and dyeing tank body 2 through a bearing. The circumferential outer wall of the stirring rod 14 is provided with five stirring components distributed at equal distances, and the stirring component includes four stirring blades 15 distributed at equal distances.

[0036] Among them, the stirring blade 15 is a "U"-shaped structure, and a screen 16 is provided near the middle position of the outer wall of one side of the stirring blade 15, and a heating wire is provided inside the stirring blade 15 (a thermometer can be added inside the printing and dyeing tank body 2 if necessary to control the temperature of the heating wire). This arrangement is convenient for the stirring rod 14 and the stirring blade 15 to drive the dye from the bottom of the printing and dyeing tank body 2 upward, and the dye flows from the screen 16 inside the stirring blade 15, thereby improving the uniformity of the dye and avoiding different degrees of dissolution and aggregation of the dye in different areas. At the same time, a heating wire is provided in the stirring blade 15, which can heat the stirring blade 15 when it contacts the dye, improve the dissolution speed and dissolution degree of the dye, make the dye easier to mix with the fabric body 13, and improve the uniformity and efficiency of dyeing. The design of the stirring blade 15 with a "U"-shaped structure can increase the coverage area of ​​stirring and improve the uniformity of stirring. This structure can better mix with the dye and the fabric body 13, ensuring that the fabric body 13 can evenly contact the dye, thereby obtaining a uniform dyeing effect.

[0037] Specifically, when in use, the first motor 3 is started, and the output shaft of the first motor 3 drives the stirring rod 14 to rotate, thereby driving the five stirring components to rotate. The continuous stirring of the stirring blades 15 can effectively prevent the dye from forming precipitation at the bottom or side wall of the printing and dyeing tank body 2.

[0038] Reference Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the moving mechanism includes a second motor 17 and a limit plate 20, an outer wall of one side of the limit plate 20 is provided with an extrusion groove, an outer wall of one side of the fixed box 11 is provided with two concave plates, the second motor 17 is installed on the inner wall of one side of the fixed box 11, and the output shaft of the second motor 17 is fixedly connected with a turntable 19, and a fixing rod is provided on the outer wall of the turntable 19 close to the second motor 17, one end of the fixing rod is slidably connected to the inner wall of the extrusion groove, the top outer wall and the bottom outer wall of the limit plate 20 are respectively slidably connected to the two concave plates, and a moving plate 21 is provided near the middle position of the outer wall of one side of the limit plate 20, and the outer wall of one side of the moving plate 21 is slidably connected to the inner wall of one side of the fixed box 11, and the mounting rod 18 is fixedly installed on the top outer wall of the moving plate 21.

[0039] Specifically, when in use, the output shaft of the second motor 17 will drive the turntable 19 to rotate, and the turntable 19 will drive the fixed rod to rotate. When the fixed rod rotates, the fixed rod squeezes the extrusion groove, and the extrusion groove can drive the limit plate 20 to move back and forth left and right. The limit plate 20 will drive the movable plate 21 to move back and forth left and right, thereby driving the auxiliary dyeing mechanism to move left and right. This arrangement is convenient for dynamically spraying dye on the fabric body 13. The faster the second motor 17 rotates, the larger the spraying range.

[0040] Reference Figure 2 In a preferred embodiment, two printing rollers 6 are provided on the inner wall of the opposite side of the printing tank body 2, and the height of the printing rollers 6 is higher than the height of the stirring blades 15, so as to avoid the stirring blades 15 being obstructed by the printing rollers 6 when rotating.

[0041] Reference Figure 1 and Figure 2 In a preferred embodiment, a heating layer 7 is provided inside the printing and dyeing tank body 2. The cross-section of the printing and dyeing tank body 2 is a semicircular structure. The printing and dyeing tank body 2 with a semicircular structure has smoother curves and fewer edges and corners, which means that during the stirring and dye flowing process, the dye can flow more smoothly and is not easy to form dead corners in the tank. The built-in heating layer 7 can ensure that the dye in the printing and dyeing tank body 2 is evenly heated. When the temperature is low, the dye tends to become viscous and the fluidity is reduced, thereby increasing the risk of accumulation. The heating layer 7 can maintain the dye within a suitable temperature range, improve its fluidity and uniformity, and reduce the possibility of accumulation.

[0042] Working principle: When in use, the dye inside the printing and dyeing tank body 2 is first heated and fully stirred by the stirring mechanism, and then the valve in the installation pipe 10 is opened, and the water pump is turned on at the same time. The water pump extracts the dye inside the printing and dyeing tank body 2 through the installation pipe 10, and then uses the connecting pipe 9 to transport it to the connecting box 8. By arranging eight symmetrically distributed nozzles 12 on the bottom outer wall of the connecting box 8, the dye can be evenly sprayed on the upper surface of the cloth body 13. When used in conjunction with the moving mechanism, the dye can cover the surface of the cloth body 13. Before the cloth body 13 enters the printing and dyeing tank body 2 or after the cloth body 13 is dyed, the cloth body 13 can be pre-colored and supplemented. Then, the excess dye is squeezed out by the pressure roller, and the excess dye will drip back into the interior of the printing and dyeing tank body 2, so that the cloth body 13 is better in contact with the dye during the printing and dyeing process, thereby improving the uniformity and quality of printing and dyeing. The valve design on the installation pipe 10 allows the operator to easily control the flow of the dye. When it is necessary to stop dyeing or adjust the dye flow, it is only necessary to close or adjust the valve, and the operation is simple and quick.

The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
