[0001] The invention specifically relates to the technical field of printing and dyeing, and in particular to a high-efficiency printing and dyeing device for denim fabrics. Background Art
[0002] In the textile industry, denim fabrics have always occupied an important position, and their printing and dyeing technology is directly related to product quality, production efficiency and corporate benefits. With the development of the times, the market demand for denim fabrics has increased significantly in both quantity and quality, which has prompted continuous innovation in printing and dyeing technology, while the limitations of traditional denim fabric printing and dyeing equipment have become increasingly prominent.
[0003] In order to overcome the shortcomings of traditional printing and dyeing methods, roll dyeing technology came into being. Roll dyeing technology draws on the concept of fabric winding and continuous processing. It was originally intended to achieve a more efficient continuous dyeing process. However, during the roll dyeing process, the cloth roll may shake due to the action of centrifugal force, resulting in uneven force on the cloth inside the cloth roll, which will cause local stretching or squeezing of the cloth during the roll dyeing process, resulting in different depths of dyeing.
[0004] There are still many shortcomings in the roll dyeing equipment and process. For example, the tension control of the cloth roll during the roll dyeing process is unstable, which easily leads to deformation of the fabric; the recycling efficiency of the dye solution is low, resulting in dye waste and environmental pollution.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0025] See also Figure 1-6 In the embodiment of the present invention, a fixed seat 1 is included, a support frame 2 is provided above the fixed seat 1 and is fixedly connected to the fixed seat 1, a printing and dyeing box 3 is provided on the inner side of the support frame 2, and the printing and dyeing box 3 is fixedly connected to the support frame 2.
[0026] By adopting the above technical solution, the fixed seat 1 serves as the basic support of the entire device, providing a stable bearing platform for the printing and dyeing box 3 and other components, and the support frame 2 above the fixed seat 1 is firmly fixedly connected to the fixed seat 1, ensuring the stability of the entire device; Furthermore, it can withstand various forces generated during the printing and dyeing process, such as the rotational inertia force of the rotating parts in the printing and dyeing box 3, the gravity and impact force of the liquid, etc. When the printing and dyeing box 3 is performing printing and dyeing operations, a large force may be generated due to the movement of the liquid and the cloth, and the stable connection between the fixed seat 1 and the support frame 2 can prevent the entire device from shaking or tipping over, thereby ensuring the safety and stability of the production process.
[0027] In this embodiment, a rotating shaft 5 is provided at the bottom of the printing and dyeing box 3 and is rotatably connected to the printing and dyeing box 3. One end of the rotating shaft 5 extends into the interior of the printing and dyeing box 3, and a roller 31 is fixedly connected to the end face of the rotating shaft 5, and a second convex shaft 33 is fixedly connected to the inner bottom of the roller 31; the other end of the rotating shaft 5 is equipped with and installed with a pulley.
[0028] By adopting the above technical solution, the rotating shaft 5 at the bottom of the printing and dyeing box 3 is rotatably connected to the printing and dyeing box 3, and the end surface of one end of the rotating shaft 5 is fixedly connected with the roller 31, so that the rotational movement of the rotating shaft 5 can be directly transmitted to the roller 31. When the private service electric 4 drives the rotating shaft 5 to rotate through the pulley, the roller 31 rotates accordingly, so that the cloth roll 34 continues to rotate in the roller 31, so that the cloth roll 34 is evenly treated with the dye liquid, ensuring the effective transmission of power and ensuring that the roller 31 can stably drive the cloth roll 34 to perform efficient printing and dyeing operations; Furthermore, the second convex shaft 33 fixedly connected to the inner bottom of the drum 31 cooperates with the structure of the cloth roll 34, which helps to stably install the cloth roll 34 in the drum 31. When the drum 31 rotates, the center position of the cloth roll 34 is fixed under the support of the second convex shaft 33, preventing the cloth roll 34 from shifting or shaking during rotation, thereby ensuring the stability of the cloth roll 34 during the printing and dyeing process.
[0029] In this embodiment, a printing and dyeing box cover 8 is provided on the top of the printing and dyeing box 3, and the printing and dyeing box cover 8 is movably connected to the printing and dyeing box 3. A fixed block is fixedly connected to the inner side of the printing and dyeing box cover 8, and a bearing 10 is installed in the fixed block. A first convex shaft 11 is installed in the bearing 10, and the first convex shaft 11 is rotatably connected to the bearing 10.
[0030] By adopting the above technical solution, the first convex shaft 11 is rotatably connected with the bearing 10, and the second convex shaft 33 and other components at the bottom of the printing and dyeing box are combined to provide accurate installation and positioning for the cloth roll. The cloth roll 34 can be accurately installed by cooperating with the first convex shaft 11 and the second convex shaft 33. During the printing and dyeing process, the center position of the cloth roll 34 is fixed without deviation or shaking. Furthermore, the printing and dyeing box cover 8 is movably connected to the printing and dyeing box 3, which facilitates the operator to operate the inside of the printing and dyeing box 3, such as putting the cloth roll 34 into or taking it out of the printing and dyeing box 3, checking and adjusting the internal components of the printing and dyeing equipment, and cleaning and maintaining the printing and dyeing box 3.
[0031] In this embodiment, a spray pipe 9 is provided on the outer side of the bearing 10 , and the spray pipe 9 is in a ring shape and is fixedly connected to the printing and dyeing box cover 8 . A plurality of spray heads 12 are provided at the bottom of the spray pipe 9 .
[0032] By adopting the above technical solution, the spray pipe 9 is annular and fixedly connected to the printing and dyeing box cover 8, ensuring that the dye liquid can evenly cover the cloth roll 34 below from multiple directions. Due to its annular shape, the dye liquid can be evenly distributed above the cloth roll, ensuring that the amount of dye liquid received by each part of the denim fabric during the printing and dyeing process is basically the same, laying a foundation for improving the printing and dyeing quality; Furthermore, the multiple spray heads 12 opened at the bottom of the spray pipe 9 further enhance the uniform distribution effect of the dye liquid. The multiple spray heads 12 work simultaneously, and can spray the dye liquid onto the cloth roll 34 in a shorter time, thereby accelerating the contact speed between the dye liquid and the cloth roll 34, and allowing the dye liquid to penetrate into the fabric fiber faster, thereby shortening the time required for printing and dyeing and improving production efficiency.
[0033] In this embodiment, a hole is opened on the spray pipe 9 on the printing and dyeing box cover 8, and a circulation hose 7 is arranged in the hole. One end of the circulation hose 7 is connected to the spray pipe 9 nut.
[0034] By adopting the above technical solution, the circulation hose 7 realizes the circulation of dye liquid, ensures the stable supply of dye liquid, and reduces the printing and dyeing quality problems caused by the interruption or instability of dye liquid supply. During the printing and dyeing process, the stable supply of dye liquid helps to maintain the consistency of printing and dyeing, avoids the color unevenness, color spots and the like caused by the fluctuation of the dye liquid amount, and ensures the printing and dyeing quality of the denim fabric.
[0035] In this embodiment, a cloth roll 34 is arranged inside the drum 31, and an adaptive channel is reserved at the center position of the cloth roll 34, which is precisely docked and tightly connected with the first convex shaft 11 and the second convex shaft 33; a liquid guide plate 32 is provided at the bottom of the drum 31, and the liquid guide plate 32 is rotatably connected to the rotating shaft 5, and the bottom of the liquid guide plate 32 is fixedly connected to the bottom plate of the printing and dyeing box 3.
[0036] By adopting the above technical solution, the cloth roll 34 is precisely docked and tightly connected with the first convex shaft 11 and the second convex shaft 33, ensuring the stable installation of the cloth roll 34 in the drum 31. During the rotation of the drum 31, good concentricity and position stability can be maintained. During the printing and dyeing process, the cloth roll 34 is prevented from deviating or shaking during rotation, thereby preventing problems such as uneven dyeing and pattern deformation caused by unstable position.
[0037] In this embodiment, a hole is opened at the bottom of the printing and dyeing box 3, and a drain pipe 13 is fixedly connected in the hole. A water pump 6 is provided at the other end of the drain pipe 13, and is fixedly connected to the water inlet of the water pump 6. The water pump 6 is fixedly connected to the fixed seat 1, and the drain outlet of the water pump 6 is fixedly connected to the other end of the circulation hose 7.
[0038] By adopting the above technical solution, the hole opened at the bottom of the printing and dyeing box 3 and the drainage pipe 13 fixedly connected thereto, together with the water pump 6 and the circulation hose 7, form a complete dye liquid circulation system, so that the dye liquid can be recycled, thereby improving the utilization efficiency of the dye liquid. During the printing and dyeing process, part of the dye liquid that is not fully absorbed by the cloth roll 34 will settle at the bottom of the printing and dyeing box 3. Through the circulation system, the dye liquid can be sent back to the printing and dyeing process, thereby avoiding the waste of dye liquid and reducing production costs.
[0039] In this embodiment, there are three support frames 2, which are arranged in a triangular shape. A rectangular groove is opened in the support frame 2, and a fixing column 21 is provided in the groove. A buffer spring 22 is installed on the fixing column 21, and a connecting plate 23 is installed on the fixing column 21. The other end of the connecting plate 23 is fixedly connected to the outer wall of the printing and dyeing box 3.
[0040] By adopting the above technical solution, the triangular support frame 2 structure can provide a stable support. When the drum 31 in the printing and dyeing box 3 rotates or the dye liquid flows, vibration and lateral force may be generated. The triangular support frame 2 can effectively resist these forces to prevent the equipment from tilting or displacement. Furthermore, the buffer spring 22 installed on the fixed column 21 plays a buffering and shock-absorbing role during the operation of the printing and dyeing equipment. During the printing and dyeing operation, the rotation of the drum 31, the rotation of the cloth roll 34, the flow of the dye liquid, etc., will generate certain impact forces and vibrations. These forces will have adverse effects on the structure and components of the equipment. The buffer spring 22 can absorb and alleviate these impacts and vibrations, reduce the vibration amplitude of the equipment, and make the printing and dyeing equipment run more smoothly.
[0041] In this embodiment, a private service motor 4 is provided on one side of the printing and dyeing box 3, and a pulley is installed at one end of the output shaft of the private service motor 4, and is connected to the pulley installed at the other end of the rotating shaft 5 through a belt.
[0042] By adopting the above technical scheme, the transmission connection between the private service motor 4 and the pulley and belt provides accurate and stable power transmission for the denim fabric printing and dyeing device, realizes continuous printing and dyeing operation, improves the degree of automation of the equipment, and also brings many conveniences to the scalability, flexibility and maintenance of the equipment, which helps to improve the overall performance and production efficiency of the printing and dyeing equipment.
[0043] The working principle of the present invention is as follows: first, the denim fabric to be printed and dyed is made into a cloth roll 34, and the cloth roll 34 is precisely docked and tightly connected with the first convex shaft 11 and the second convex shaft 33 through the hole reserved at the center position of the cloth roll 34, so that it is installed inside the drum 31, ensuring that the cloth roll 34 can run stably in the subsequent printing and dyeing process, and avoiding the displacement or shaking of the cloth roll 34 to affect the printing and dyeing quality; The private service motor 4 is started. A pulley is installed at one end of the output shaft of the private service motor 4. The pulley is connected to the pulley installed at the other end of the rotating shaft 5 through a belt. When the private service motor 4 rotates, the power is transmitted to the rotating shaft 5 through the transmission system of the pulley and the belt, driving the rotating shaft 5 to rotate. Since the rotating shaft 5 is rotatably connected to the printing and dyeing box 3, and the roller 31 is fixedly connected to the end surface of the rotating shaft 5, the rotation of the rotating shaft 5 will cause the roller 31 to rotate accordingly. While the roller 31 rotates, the annular spray pipe 9 on the outer side of the bearing 10 on the inner side of the printing and dyeing box cover 8 starts to work. The dye enters the spray pipe 9 through the circulating hose 7, and is evenly sprayed on the cloth roll 34 from the multiple spray heads 12 opened at the bottom of the spray pipe 9. The spray head 12 ensures that the dye can be evenly dispersed on the surface of the cloth roll 34, avoiding local concentration or uneven distribution of the dye, thereby achieving uniform dye spraying; As the drum 31 rotates, the cloth roll 34 rotates with it. During this process, since the cloth roll 34 is tightly connected to the first convex shaft 11 and the second convex shaft 33, the cloth roll 34 can stably rotate in the drum 31, so that the dye can better penetrate into various parts of the cloth roll 34 under the action of centrifugal force. The existence of centrifugal force makes the dye more evenly distributed inside the cloth roll 34, which promotes full contact between the dye and the fabric fibers, and also improves the penetration speed and efficiency of the dye, which helps to shorten the printing and dyeing time.
