Description

Technical Field

[0001] This invention relates to the field of printing steaming, and more particularly to a high-temperature steaming device for dispersion direct-to-garment digital printing. Background Technology

[0002] In the textile printing and dyeing industry, dispersive direct-to-garment digital printing technology has gradually become one of the mainstream printing processes due to its advantages such as high precision and personalized customization. High-temperature steaming equipment, as a key piece of equipment in the dispersive direct-to-garment digital printing production process, directly affects the quality of the printed fabric and production efficiency. Traditional high-temperature steaming equipment presents numerous problems during operation. Firstly, the steaming process generates a large amount of excess steam, which, if not properly managed, will directly diffuse into the surrounding environment. This not only causes a significant increase in humidity within the workshop, affecting the comfort and health of operators, but may also damage other equipment, reducing its lifespan and stability. Simultaneously, the indiscriminate release of chemicals contained in the steam pollutes the surrounding environment, failing to meet current green and environmentally friendly production requirements. Secondly, the steamed fabric usually contains a large amount of moisture, and traditional equipment lacks an effective dewatering process. Excessive moisture will lead to longer subsequent drying times, increased energy consumption, and reduced overall production efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-temperature steaming device for direct-to-garment digital printing. When in use, this device can easily absorb, condense, and recycle excess steam to prevent it from spreading to the surrounding environment and affecting it. In addition, it can also perform a water-squeezing operation on the steamed fabric to facilitate subsequent drying.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A high-temperature steaming device for direct-to-garment digital printing includes a steaming chamber with a liquid collection tank at its bottom and strip-shaped openings on both sides, with a fabric body mounted on each opening; a steaming mechanism including a flow-diverting hollow plate mounted on the top of the steaming chamber, with multiple nozzles mounted on the lower end of the plate and a steam inlet pipe connected to the upper end; a water-pressing mechanism including two pressing rollers rotatably connected between the front and rear inner walls of the steaming chamber, with the fabric body located between the two rollers, and the rear ends of the rotating shafts of the two rollers extending to the outside and equipped with transmission gears that mesh; a drive mechanism for driving the water-pressing mechanism; and a steam recovery mechanism for recovering excess steam.

[0005] Preferably, the drive mechanism includes a mounting bracket installed on the front side of the steaming chamber, on which a drive motor is mounted. The output shaft of the drive motor extends into the steaming chamber and is fixedly connected to the front rotating shaft of one of the rolling rollers.

[0006] Preferably, the steam recovery mechanism includes a cooling box fixedly connected to the lower end of the vaporization box, a collection box fixedly connected to the lower end of the cooling box, a spiral condenser tube inside the cooling box, a first hose and a second hose respectively connected to the upper and lower ends of the spiral condenser tube, the other end of the first hose extending into the liquid collection tank, and the other end of the second hose extending into the collection box.

[0007] Preferably, a negative pressure pump is installed on the rear side of the evaporation box, and a filter box is fixedly connected to the right side of the evaporation box. The air inlet of the negative pressure pump extends to the inner top of the filter box, and the inner bottom of the filter box is connected to the top space of the collection box through a connecting pipe.

[0008] Preferably, a U-shaped plate is provided inside the cooling box, and the upper and lower ends of the spiral condenser tube pass through the U-shaped plate and are fixedly connected. Multiple guide rods are fixedly connected between the inner walls of the left and right sides of the cooling box, and the multiple guide rods all pass through the U-shaped plate and are slidably connected. The right side of the U-shaped plate is elastically connected to the right side wall of the cooling box through multiple springs. A rotating shaft is rotatably connected between the front and rear inner walls of the cooling box, and a cam is fixedly connected on the rotating shaft. The cam abuts against the U-shaped plate.

[0009] Preferably, the front end of the rotating shaft extends to the outside, and both the output shaft of the drive motor and the rotating shaft are equipped with first synchronous pulleys, which are connected by a first synchronous belt drive.

[0010] Preferably, it also includes an air-cooling mechanism, which includes multiple air holes opened on the front side wall of the cooling box. A connecting ring is fixedly connected to the rear side of the cooling box. The connecting ring is connected to the interior of the cooling box. An installation strip is fixedly connected to the rear side of the connecting ring. A gearbox is fixedly connected to the rear side of the installation strip. The output end of the gearbox passes through the installation strip and is fixedly connected to multiple cooling fan blades.

[0011] Preferably, the output shaft of the lower roller's rear end passes through a corresponding transmission gear, and a second synchronous pulley is installed on both the output shaft of the lower roller's rear end and the input shaft of the gearbox. The two second synchronous pulleys are connected by a second synchronous belt.

[0012] Compared with the prior art, the beneficial effects of this invention are as follows: 1. The drive mechanism drives two pressing rollers to rotate relative to each other, squeezing the main body of the fabric. This squeezes out excess water and some unfixed dye solution from the fabric, reducing the burden on subsequent drying processes and making the fabric smoother, thus further improving the steaming quality.

[0013] 2. The negative pressure pump generates a unidirectional airflow, which causes the vaporized waste gas to flow into the filter box. After being filtered by the filter element, clean gas is discharged, effectively treating the vaporized waste gas, reducing environmental pollution, and creating a good working environment.

[0014] 3. The vaporized steam is condensed into liquid through a collection tank and spiral condenser tubes, then enters a collection box, achieving steam recovery and utilization, thus saving resources. Furthermore, the vibrating design of the spiral condenser tubes reduces the possibility of water adhesion, improves heat exchange and condensation effects, and enhances steam recovery efficiency.

[0015] 4. The lower roller drives the cooling fan blades to rotate at high speed through transmission, generating strong airflow to cool the spiral condenser tubes inside the cooling box, further enhancing the cooling effect, improving steam recovery efficiency, and ensuring stable and efficient operation of the equipment.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0020] Reference Figures 1-6 A high-temperature steaming device for direct-to-garment digital printing includes a steaming chamber 1, a liquid collection tank 24 at the bottom of the steaming chamber 1, and strip-shaped openings 3 on both the left and right sides of the steaming chamber 1. A fabric body 4 is mounted on both strip-shaped openings 3. The device also includes an external winding and unwinding device (not shown). When the two devices are in operation, the fabric body 4 can enter and exit the steaming chamber 1 through the strip-shaped openings 3 to achieve continuous steaming operation.

[0021] The system also includes a steaming mechanism, which comprises a hollow distribution plate 21 installed at the top of the steaming chamber 1. Multiple nozzles 22 are mounted on the lower end of the hollow distribution plate 21, and a steam inlet pipe 2 connects to the upper end of the hollow distribution plate 21. An external steam source delivers steam to the hollow distribution plate 21 through the steam inlet pipe 2, and then the steam is sprayed out through the nozzles 22. During operation, steam continuously enters the hollow distribution plate 21 from the steam inlet pipe 2, and is then evenly sprayed onto the fabric body 4 through the multiple nozzles 22. This allows the fabric to complete the steaming process under the action of high-temperature steam, improving the dye fixation rate and making the printed pattern more vibrant and clear.

[0022] The system also includes a water-pressing mechanism, which comprises two pressing rollers 23 rotatably connected between the front and rear inner walls of the steaming chamber 1. The fabric body 4 is located between the two pressing rollers 23. The rear ends of the rotating shafts of both pressing rollers 23 extend to the outside and are equipped with transmission gears 20. The two transmission gears 20 mesh, and during operation, the two pressing rollers 23 rotate relative to each other, squeezing the fabric body 4. This squeezes out excess water and some unfixed dye solution from the fabric, reducing the burden on subsequent drying processes and making the fabric smoother, thus improving the steaming quality. Furthermore, the meshing transmission gears 20 ensure the synchronicity and stability of the rotation of the two pressing rollers 23.

[0023] It also includes a drive mechanism for driving the water pressing mechanism. The drive mechanism includes a mounting bracket 8 installed on the front side of the steaming box 1. A drive motor 9 is mounted on the mounting bracket 8. The output shaft of the drive motor 9 extends into the steaming box 1 and is fixedly connected to the front end rotating shaft of one of the rolling rollers 23.

[0024] It also includes a steam recovery mechanism for recovering excess steam. The steam recovery mechanism includes a cooling box 6 fixedly connected to the lower end of the vaporization box 1. A collection box 7 is fixedly connected to the lower end of the cooling box 6. A spiral condenser 25 is installed inside the cooling box 6. The upper and lower ends of the spiral condenser 25 are respectively connected to a first hose 29 and a second hose 33. The other end of the first hose 29 extends into the liquid collection tank 24, and the other end of the second hose 33 extends into the collection box 7. A negative pressure pump 13 is installed at the rear of the vaporization box 1. A filter box 5 is fixedly connected to the right side of the vaporization box 1. A filter element is installed inside the filter box 5 to absorb the polluting waste gas generated during vaporization. The air inlet of the negative pressure pump 13 extends to the top of the filter box 5. The bottom of the filter box 5 is connected to the top space of the collection box 7 through a connecting pipe 26. When the negative pressure pump 13 is working, it can generate a unidirectional airflow between the vaporization box 1, the cooling box 6, the collection box 7 and the filter box 5, which causes the waste gas generated during vaporization to flow to the filter box 5. After being filtered by the filter element, the clean gas is discharged, while the steam is condensed at the spiral condenser tube 25, and the condensate enters the collection box 7. The cooling box 6 is equipped with a U-shaped plate 27. The upper and lower ends of the spiral condenser tube 25 pass through the U-shaped plate 27 and are fixedly connected. Multiple guide rods 28 are fixedly connected between the inner walls of the left and right sides of the cooling box 6. The multiple guide rods 28 all pass through the U-shaped plate 27 and are slidably connected. The right side of the U-shaped plate 27 is elastically connected to the right side wall of the cooling box 6 through multiple springs 30. A rotating shaft 32 is rotatably connected between the front and rear inner walls of the cooling box 6. A cam 31 is fixedly connected to the rotating shaft 32. The cam 31 abuts against the U-shaped plate 27. The front end of the rotating shaft 32 extends to the outside. The output shaft of the drive motor 9 and the rotating shaft 32 are both equipped with first synchronous pulleys 11. The two first synchronous pulleys 11 are synchronously connected to the first synchronous belt 10. After the cam 31 rotates, the spiral condenser tube 25 can vibrate, reducing the possibility of water adhering inside, improving the heat exchange effect, and increasing the condensation effect.

[0025] The system also includes an air-cooling mechanism, which includes multiple air holes 12 on the front side wall of the cooling box 6. A connecting ring 14 is fixedly connected to the rear side of the cooling box 6 and is connected to the interior of the cooling box 6. An mounting strip 15 is fixedly connected to the rear side of the connecting ring 14 and a gearbox 16 is fixedly connected to the rear side of the mounting strip 15. The gearbox 16 is an accelerator that can amplify the output speed of the input shaft. The output end of the gearbox 16 passes through the mounting strip 15 and is fixedly connected to multiple cooling fan blades 17. The rear output shaft of the lower roller 23 passes through the corresponding transmission gear 20. The rear output shaft of the lower roller 23 and the input shaft of the gearbox 16 are both equipped with second synchronous pulleys 18. The two second synchronous pulleys 18 are connected by a second synchronous belt 19. The lower roller 23 rotates, which drives the input shaft of the gearbox 16 to rotate through the second synchronous pulley 18 and the synchronous belt 19. After being accelerated by the gearbox 16, the output shaft drives the cooling fan blades 17 to rotate at high speed, generating strong wind to cool the spiral condenser tubes 25 in the cooling box 6, further enhancing the cooling effect and improving the steam recovery efficiency.

[0026] In this invention, the external winding and unwinding device operates, driving the main body of the fabric 4 to enter and exit the steaming box 1 through the strip-shaped openings 3 on the left and right sides of the steaming box 1, thereby realizing continuous steaming operation.

[0027] An external steam source delivers steam through a steam inlet pipe 2 to a distribution hollow plate 21 installed at the top of the steaming chamber 1. The steam is then evenly sprayed onto the fabric body 4 by multiple nozzles 22 installed at the lower end of the distribution hollow plate 21, so that the fabric completes the steaming process under the action of high-temperature steam, thereby improving the fixation rate of the dye and making the printed pattern more vivid and clear.

[0028] The drive mechanism starts working, and the drive motor 9, mounted on the mounting bracket 8 on the front side of the steaming chamber 1, starts. Its output shaft extends into the steaming chamber 1 and is fixedly connected to the front rotating shaft of one of the pressing rollers 23, driving the pressing roller 23 to rotate. Since the rear ends of the rotating shafts of both pressing rollers 23 extend to the outside and are equipped with meshing transmission gears 20, the two pressing rollers 23 rotate relative to each other, squeezing the fabric body 4, squeezing out excess water and some unfixed dye solution from the fabric, reducing the burden on subsequent drying processes, and making the fabric smoother and improving the steaming quality. When the negative pressure pump 13 is working, it generates a unidirectional airflow through the vaporization box 1, cooling box 6, collection box 7 and filter box 5, causing the waste gas generated during the vaporization process to flow into the filter box 5. After being filtered by the filter element inside the filter box 5, the clean gas is discharged.

[0029] The steam generated during the vaporization process enters the collection tank 24, and the steam in the collection tank 24 enters the spiral condenser tube 25 inside the cooling box 6 through the first hose 29. The steam condenses at the spiral condenser tube 25, and the condensate enters the collection box 7 through the second hose 33.

[0030] When the drive motor 9 is working, its output shaft is connected to the first synchronous pulley 11 on the rotating shaft 32 through the first synchronous belt 10, which drives the rotating shaft 32 to rotate. The cam 31 on the rotating shaft 32 rotates accordingly. The cam 31 abuts against the U-shaped plate 27. During the rotation of the cam 31, the U-shaped plate 27 slides on the guide rod 28 and reciprocates under the action of the spring 30, thereby causing the spiral condenser tube 25 to vibrate, reducing the possibility of water adhering inside, improving the heat exchange effect, and increasing the condensation effect.

[0031] When the lower roller 23 rotates, its rear output shaft is connected to the second synchronous pulley 18 on the input shaft of the gearbox 16 via the second synchronous belt 19, driving the input shaft of the gearbox 16 to rotate. After acceleration by the gearbox 16, the output shaft drives the cooling fan blades 17 to rotate at high speed, generating strong airflow. This airflow enters the cooling box 6 through multiple air holes 12 on the front side wall of the cooling box 6, providing air cooling for the spiral condenser tubes 25 inside the cooling box 6, further enhancing the cooling effect and improving the steam recovery efficiency.
