Description

Technical Field

[0001] This application relates to the technical field of printing and dyeing equipment, and in particular to an energy-saving printing and dyeing device. Background Technology

[0002] In the textile printing and dyeing industry, fabric printing and dyeing is a core link to enhance the diversity of textile appearance and market competitiveness. When printing on fabrics, traditional printing and dyeing equipment needs to dye the fabric first to give it a base color. During the dyeing process, the fabric is continuously driven into the dyeing tank by the conveyor roller group, so that the fabric is completely immersed in the dye solution. By taking advantage of the adsorption characteristics of the fabric fibers, the dye molecules are evenly attached to the surface and inside of the fibers, thereby changing the color of the fabric.

[0003] During fabric dyeing, after the fabric passes through the dye bath and leaves the dye bath under the action of conveyor rollers, a large amount of dye adheres to the fabric surface and between the fibers. Because traditional equipment lacks an effective dye bath interception and recovery structure, this adhered dye is carried out of the dye bath with the movement of the fabric. Some dye drips onto the outside of the equipment or the ground due to gravity during fabric transport. This dripping dye not only cannot re-enter the dye bath for recycling, resulting in waste, but also forms stagnant water on the ground. If not cleaned promptly, it can easily seep into the soil or enter the environment through wastewater discharge systems, polluting surrounding water bodies and soil. Utility Model Content

[0004] In order to overcome the problem that a large amount of dye liquor adheres to the surface of existing fabrics and between fibers, and that traditional devices lack effective dye liquor interception and recovery structures, these adhered dye liquors are carried out of the dyeing tank as the fabric moves, and some dye liquors drip onto the outside of the equipment or the ground due to gravity during the fabric transport process, this application provides an energy-saving printing and dyeing device.

[0005] The energy-saving dyeing and printing device provided in this application adopts the following technical solution: An energy-saving dyeing and printing device includes a dyeing box, a scraping assembly, and a drying lamp box. The dyeing box has an opening on its top surface, and guide rollers are horizontally rotatably connected to both the top and interior of the dyeing box. Fabric is guided and transported inside the dyeing box via the guide rollers. Two scraping assemblies are symmetrically arranged inside the dyeing box on the fabric outlet side, and the two scraping assemblies are used to scrape off the dye from the side end face of the fabric. The scraping assembly includes a fixing plate, mounting bases, and mounting strips. The fixing plate is vertically fixed to the inner wall of the dyeing box, and two mounting bases are horizontally slidably inserted into the vertical end face of the fixing plate near the fabric. A rigid scraper and multiple elastic scrapers are assembled sequentially from top to bottom on the two mounting bases, and the rigid scraper and multiple elastic scrapers are used to press against the fabric surface. A drying lamp box is vertically fixed to the dyeing box on the fabric outlet side, and the fabric is threaded through the drying lamp box.

[0006] By adopting the above technical solution, the dyeing box is used to carry and transport fabric for dyeing. Its top opening facilitates the entry and exit of the fabric, and the internal guide rollers ensure that the fabric passes through smoothly and at a uniform speed during the dyeing process. The scraper assembly is fixed to the inner wall of the dyeing box by a fixing plate, and features two different materials: a hard scraper and a flexible scraper, which effectively removes excess dye from the fabric surface, improving dyeing accuracy and uniformity. The drying lamp box is located on the fabric exit side, using ultraviolet light to cure the fabric surface, accelerating dye fixing and reducing energy consumption. During operation, the fabric is conveyed at a uniform speed by the guide rollers inside the dyeing box. After being scraped twice by the scraper assembly, it enters the drying lamp box where ultraviolet light cures the surface dye, thus achieving efficient printing and dyeing production while ensuring dyeing quality.

[0007] Optionally, a stirring rod is horizontally rotatably connected to the lower inner side of the dyeing box, and multiple stirring blades are fixed on the outer wall of the stirring rod. A stirring motor is horizontally fixed at one end of the dyeing box, and the output end of the stirring motor is fixed at the end of the stirring rod.

[0008] By adopting the above technical solution, a rotatable stirring rod is horizontally installed on the lower inner side of the dyeing box. Multiple stirring blades are fixed to the outer wall of the stirring rod. During the dyeing process, the stirring rod and blades are rotated to effectively mix the dye and fabric, ensuring uniform dyeing. A stirring motor is fixed to one end of the dyeing box and drives the stirring rod by rotating it to the end of the stirring rod, thereby achieving thorough mixing during the dyeing process.

[0009] Optionally, an air jet box plate is horizontally fixed to the lower inside of the dyeing box, and multiple nozzles are uniformly and vertically connected and fixed on the air jet box plate.

[0010] By adopting the above technical solution, the jet box plate is horizontally fixed on the lower side of the dyeing box, and multiple nozzles are evenly distributed on it to evenly disperse and discharge air into the dyeing box.

[0011] Optionally, the bottom air inlet of the jet box plate is connected to an air pipe that penetrates the bottom surface of the dyeing box, and an air pump is fixedly connected to the air pipe of the jet box plate.

[0012] By adopting the above technical solution, the jet box plate is connected to an external air pump through an air pipe. The air pump is used to deliver gas to each nozzle. The jet airflow can help the gas and dye mix better, and at the same time help to improve the dispersion effect of the dye in the solution, thereby improving the dyeing uniformity and dyeing efficiency.

[0013] Optionally, a sliding rod is horizontally fixed on the vertical end face of the mounting base near the fixed plate, and the sliding rod on the mounting base is slidably connected in the fixed plate.

[0014] By adopting the above technical solution, the fixing plate serves as a fixed base, providing support and guidance for the mounting base. A sliding rod is horizontally fixed on the vertical end face of the mounting base near the fixing plate. The sliding rod slides inside the fixing plate, ensuring that the movement of the mounting base is controlled and stable.

[0015] Optionally, a compression spring is horizontally fitted on the outside of the slide rod, and the two ends of the compression spring are fixed to the end of the slide rod and the fixed plate, respectively.

[0016] By adopting the above technical solution, the two ends of the compression spring sleeved on the slide rod are fixed to the end of the slide rod and the fixed plate, respectively. When the mounting seat moves, the compression spring can apply a certain resistance to it and provide a rebound force after the movement is completed, so that the mounting seat can be stably kept in the required position.

[0017] Optionally, a pull rod is horizontally slidably inserted into the top surface of the mounting strip, and a spring is horizontally sleeved on the pull rod, with the two ends of the spring fixed to the mounting strip and the pull rod respectively.

[0018] By adopting the above technical solution, the mounting strip, as the main support structure, provides a sliding track for the tie rod, ensuring its stability during horizontal sliding. The tie rod connects the mounting strip and the spring, and its sliding motion can cause other components on the tie rod to move. The spring provides elastic force, and by fixing its two ends to the mounting strip and the tie rod respectively, it can provide restoring force when the tie rod slides, maintaining the balance and elasticity of the device.

[0019] Optionally, the mounting base has a horizontally oriented positioning hole, and the positioning hole is slidably inserted into the pull rod.

[0020] By adopting the above technical solution, the mounting base fixes the device and provides positioning holes to achieve sliding positioning of the pull rod, so that the entire device can accurately perform relative movement at a specific position.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. A scraping assembly combining a rigid scraper and multiple elastic scrapers enables precise dye liquor recovery: When the fabric emerges from both sides of the dyeing tank after dyeing, the mounting base, under the elastic force of the compression spring, pushes the rigid scraper and elastic scraper to press tightly against the fabric surface. The rigid scraper can first scrape off a large amount of free dye liquor adhering to the fabric surface, while the multiple elastic scrapers, through their own elastic deformation, conform to the fabric texture and further scrape off the residual dye liquor in the fiber gaps, preventing the dye liquor from being carried out of the dyeing tank with the movement of the fabric. The scraped dye liquor can be directly returned to the inside of the dyeing tank and re-participated in the fabric dyeing cycle, completely changing the situation of dye liquor being carried out and wasted by dripping in traditional devices. 2. The dual anti-stratification structure of stirring and air jet ensures that the dye liquor remains uniform at all times: On the one hand, the stirring motor on the lower side of the dyeing box drives the stirring rod to rotate continuously, which can stir the dye liquor to form a circulating flow and prevent dye particles from settling; on the other hand, the air pump sends external air into the air jet box plate, and the air is sprayed into the dyeing box through the air jet nozzle. The sprayed air forms dense micro bubbles in the dye liquor and rises. During the rise of the bubbles, the water flow is driven to generate convection, which promotes uniform mixing of the water and ensures that the dye does not stratify. Attached Figure Description

[0025] This application discloses an energy-saving printing and dyeing apparatus. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 5An energy-saving dyeing and printing device includes a dyeing box 1, a scraping assembly 2, and a drying lamp box 3. The top surface of the dyeing box 1 is open, and the top and interior of the dyeing box 1 are horizontally rotatably connected to guide rollers 11. The dyeing box 1 is guided and transported with fabric through the guide rollers 11. Two scraping assemblies 2 are symmetrically arranged inside the dyeing box 1 on the fabric discharge side. The two scraping assemblies 2 are used to scrape off the dye on the side end face of the fabric. The scraping assembly 2 includes a fixing plate 21, a mounting seat 22, and a mounting strip 25. The fixing plate 21 is vertically fixed to the inner wall of the dyeing box 1. Two mounting seats 22 are horizontally slidably inserted on the vertical end face of the fixing plate 21 near the fabric. Hard scraper 26 and multiple elastic scraper 27 are assembled sequentially from top to bottom on the two mounting seats 22. The hard scraper 26 and multiple elastic scraper 27 are used to press against the surface of the fabric. The drying lamp box 3 is vertically fixed on the side of the dyeing box 1 where the fabric discharges, and the fabric is threaded through the drying lamp box 3.

[0026] By adopting the above technical solution, the dyeing box 1 is used to carry and transport fabric for dyeing. Its top opening facilitates the entry and exit of the fabric, and the internal guide rollers 11 ensure that the fabric passes through smoothly and at a uniform speed during the dyeing process. The scraper assembly 2 is fixed to the inner wall of the dyeing box 1 by a fixing plate 21. It has two different materials, a hard scraper 26 and an elastic scraper 27, which can effectively remove excess dye from the fabric surface, improving dyeing accuracy and uniformity. The drying lamp box 3 is set on the fabric exit side, and uses ultraviolet light to cure the fabric surface, accelerating the dye fixing speed and reducing energy consumption. During operation, the fabric is uniformly transported by the guide rollers 11 inside the dyeing box 1. After being scraped twice by the scraper assembly 2, it enters the drying lamp box 3 where the surface dye is cured by ultraviolet light, thereby achieving efficient printing and dyeing production while ensuring dyeing quality.

[0027] Reference Figure 4 A stirring rod 12 is horizontally rotatably connected to the lower interior of the dyeing chamber 1, and multiple stirring blades are fixed to the outer wall of the stirring rod 12. A stirring motor 13 is horizontally fixed to one end of the dyeing chamber 1, and the output end of the stirring motor 13 is fixed to the end of the stirring rod 12. The stirring rod 12, which can rotate horizontally, is used to effectively mix the dye and fabric during the dyeing process by rotating the stirring rod 12 and the stirring blades, ensuring uniform dyeing. The stirring motor 13 is fixed to one end of the dyeing chamber 1 and drives the stirring rod to perform stirring operations by rotating it to the end of the stirring rod, thereby achieving thorough mixing during the dyeing process.

[0028] An air jet plate 14 is horizontally fixed to the lower interior of the dyeing chamber 1, and multiple nozzles are evenly and vertically connected and fixed on the air jet plate 14. The air jet plate 14 is horizontally fixed to the lower side of the dyeing chamber 1, and the multiple nozzles are evenly distributed on it, dispersing and expelling air into the dyeing chamber 1. An air pipe is connected to the bottom air inlet of the air jet plate 14, penetrating the bottom surface of the dyeing chamber 1, and an air pump 15 is fixedly connected to the air pipe. The air jet plate 14 is connected to the external air pump 15 through the air pipe. The air pump 15 is used to deliver gas to each nozzle. The ejected airflow helps the gas and dye mix better, and also helps to improve the dispersion of the dye in the solution, thereby improving dyeing uniformity and dyeing efficiency.

[0029] Reference Figure 5 A sliding rod 23 is horizontally fixed to the vertical end face of the mounting base 22 near the fixing plate 21, and the sliding rod 23 on the mounting base 22 is slidably connected to the fixing plate 21. The fixing plate 21 serves as a fixed base, providing support and guidance for the mounting base 22. The sliding rod 23 slides inside the fixing plate 21, ensuring controlled and stable movement of the mounting base 22. A compression spring 24 is horizontally sleeved on the outside of the sliding rod 23, and both ends of the compression spring 24 are fixed to the ends of the sliding rod 23 and the fixing plate 21, respectively. When the mounting base 22 moves, the compression spring 24 applies a certain resistance and provides a rebound force after the movement is completed, allowing the mounting base 22 to be stably held in the desired position.

[0030] Reference Figure 5 A pull rod 251 is horizontally slidably inserted into the top surface of the mounting strip 25, and a spring 252 is horizontally sleeved on the pull rod 251, with both ends of the spring 252 fixed to the mounting strip 25 and the pull rod 251 respectively. The mounting strip 25, as the main support structure, provides a sliding track for the pull rod 251, ensuring stability during horizontal sliding. The pull rod 251 connects the mounting strip 25 and the spring 252, and can drive other components on the pull rod to move through its own sliding motion. The spring 252 provides elastic force, and by being fixed at both ends to the mounting strip 25 and the pull rod 251 respectively, it provides restoring force when the pull rod 251 slides, maintaining the balance and elasticity of the device. A positioning hole 221 is horizontally opened on the mounting base 22, and the positioning hole 221 is slidably inserted into the pull rod 251. The mounting base 22 fixes the device and provides the positioning hole 221 to achieve sliding positioning of the pull rod 251, enabling the entire device to accurately move relative to each other at a specific position.

[0031] The implementation principle of an energy-saving dyeing and printing device according to an embodiment of this application is as follows: First, the fabric to be dyed with the base color is guided and conveyed into the dyeing box 1 by the guide roller 11 at the top of the dyeing box 1. The fabric is dyed in the dyeing box 1. After dyeing, the fabric is conveyed upward and discharged from the dyeing box 1. At this time, the fabric is heavily dyed. The fabric passes through the scraping assembly 2 on both sides inside the dyeing box 1. Then, the pull rod 251 on the mounting strip 25 at the end of the rigid scraper 26 and multiple elastic scrapers 27 is pulled to slide, pulling the locking spring 252 to deform, thus moving the rigid scraper 26 and... The mounting strips 25 at the ends of the multiple elastic scrapers 27 are snapped onto the mounting base 22. When the pull rod 251 is released, under the deformation force of the locking spring 252, the pull rod 251 is pushed to lock into the positioning hole 221 of the mounting base 22, thus completing the assembly of the hard scraper 26 and the multiple elastic scrapers 27 with the mounting base 22. Under the deformation force of the compression spring 24, the mounting base 22 pushes the hard scraper 26 and the multiple elastic scrapers 27 to press against the fabric surface, scraping off excess dye from the fabric surface. Then, in order to ensure that the dye inside the dyeing box 1 does not separate and precipitate, the stirring motor 13 on the lower side of the dyeing box 1 is started to drive the stirring rod 12 to rotate. The rotating stirring rod 12 agitates the dye flow inside the dyeing box 1 to prevent the dye from separating. At the same time, the air pump 15 on the air inlet pipe of the air jet box plate 14 is started to drive the external air into the air jet box plate 14. Then the air is sprayed out from the air jet nozzle on the top surface of the air jet box plate 14. The sprayed air forms dense tiny bubbles in the dye liquor and rises. During the rise of the bubbles, the water flow is driven to generate convection, which promotes the uniform mixing of the water and ensures that the dye does not separate. Finally, after the fabric is dyed, it is guided by the guide roller 11 and passes through the drying lamp box 3. The halogen heating lamps installed inside the drying lamp box 3 emit light, and the fabric is dried by the high brightness of the halogen lamps and infrared heat radiation.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
