Description

Technical Field

[0001] This utility model belongs to the field of textile processing technology, and in particular relates to a multi-purpose flat plate for DTG (direct-to-garment printing) fabric processing. Background Technology

[0002] DTG direct-to-garment printing is an important method of digital printing. It uses high-precision printheads to directly spray water-based ink onto the fabric surface. Simply put, the fabric is first pretreated with a special pretreatment solution to improve ink adhesion and color fixation. Then, the printhead precisely drops ink into the designated areas of the fabric in the form of tiny droplets according to the pattern data. After printing, the fabric is dried and fixed to ensure that the pattern is washable and does not easily fade.

[0003] A heat press is a key auxiliary device for DTF direct-to-garment printing. It uses a heating plate to generate heat and apply pressure at a specific temperature and time to bond or penetrate the coating and heat-curing agent on the transfer paper onto the substrate. It is particularly suitable for making medals, commemorative certificates, tombstones, T-shirts, etc.

[0004] However, in the more advanced generation of DTG printing technology, the existing heat presses used for DTF direct-to-garment printing are not suitable. The working principle of DTF heat presses in DTG is "high temperature and high pressure + long time action". It evaporates the moisture in the fabric by high temperature (usually far exceeding 120°C). Without an active moisture absorption structure, water vapor easily accumulates and flows back under the fabric, resulting in incomplete dehumidification. This leads to ink bleeding and poor color saturation during DTG printing. Therefore, a multi-board fabric treatment for DTG (direct-to-garment printing) is needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a multi-purpose flatbed for DTG (direct-to-garment printing) fabric processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-purpose flatbed for DTG (Direct-to-Gallery) fabric processing includes:

[0008] The device body includes a workbench and multiple support plates. The multiple support plates are arranged parallel to each other on the upper surface of the workbench. The workbench is provided with an upper pressure plate that can be raised and lowered at a predetermined distance above the support plates.

[0009] A material support assembly is disposed on the upper surface of the workbench. The material support assembly includes a placement pad and a honeycomb plate adapted to the placement pad. The placement pad is installed on the upper surface of the honeycomb plate and is configured as a high-temperature resistant blanket.

[0010] A moisture-absorbing assembly includes multiple fans and multiple sets of air plates. Each set of air plates is arranged parallel to each other at intervals on the support plate, and the axial direction of the air plate is perpendicular to the axial direction of the support plate. A honeycomb panel is installed on the upper surface of the air plate. Each air plate has multiple air holes arranged at intervals. The fans are fixedly installed below the multiple air plates, and the air intake area of ​​the fans covers or is directly opposite the air holes. The fans are separated from the upper surface of the workbench by a predetermined distance.

[0011] In a further technical solution, the support plate is provided with a pair, and the main body of the device also includes a pair of slide rods and two sets of fixing blocks. Each set of fixing blocks is provided with at least one, and the fixing blocks are fixedly installed on the upper surface of the workbench. The fixing blocks have sliding grooves, and the slide rods are slidably inserted into the sliding grooves. Each slide rod is respectively installed on the lower surface of each support plate, and the axial direction of each slide rod is parallel to the axial direction of each support plate.

[0012] In a further technical solution, the material-bearing assembly also includes a metal frame, the honeycomb panel is disposed inside the metal frame, and the outer wall of the honeycomb panel is attached to the inner wall of the metal frame.

[0013] In a further technical solution, the main body of the device also includes a pair of connecting plates. The cross-section of the connecting plates is T-shaped. The end face of the connecting plate with a larger cross-sectional area is installed on the lower end face of the support plate, and the end face of the connecting plate with a smaller cross-sectional area is installed on the side wall of the slide rod. The upper end of the fixing block has a snap-fit ​​groove that communicates with the slide groove, and the lower end of the connecting plate is snapped into the snap-fit ​​groove.

[0014] In a further technical solution, the size of the honeycomb panel is set to 40*40cm or 40*60cm, and the size of the placement pad is equal to the size of the honeycomb panel.

[0015] In a further technical solution, each of the support plates has multiple spaced-apart pads on its upper surface, and the pads are fixedly connected to the honeycomb plate by bolts.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention utilizes a moisture-absorbing component, which includes a fan and multiple sets of air plates. Each set of air plates is parallel to each other and spaced apart on a support plate, with the air plate axis perpendicular to the support plate axis. A honeycomb panel is installed on the upper surface of the air plate, and each air plate has spaced air holes. The fan is fixedly installed below the air plate, with the fan's air intake area covering or directly facing the air holes. The worker lays the fabric to be treated flat on a placement mat. After the fan is started, it draws air downward to create negative pressure. At the same time, the honeycomb panel and the air holes on the air plate form an airflow channel, allowing the water vapor formed after the moisture inside the fabric on the placement mat evaporates to be discharged downward through the honeycomb panel and air holes, thus improving the dehumidification efficiency.

[0018] This invention features a placement pad mounted on the upper surface of a honeycomb panel. The placement pad is made of a high-temperature resistant material. When the upper pressure plate moves down to make close contact with the fabric, the placement pad, due to its good elasticity, deforms along the contour of the fabric. This ensures that heat is evenly distributed to the fabric and that the pressure from the upper pressure plate is evenly distributed to every loose lint area. Furthermore, the heat-insulating properties of the placement pad maintain a local temperature, ensuring that the loose lint adheres fully to the fabric fibers and preventing incomplete removal of loose lint due to insufficient local pressure.

[0019] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] like Figures 1 to 3 As shown, this utility model embodiment provides a multi-purpose fabric processing flatbed for DTG (direct-to-garment printing), comprising:

[0027] The main body of the device 1 includes a workbench 11 and multiple support plates 12. The multiple support plates 12 are arranged parallel to each other on the upper surface of the workbench 11. The workbench 11 is provided with an upper pressure plate that can be raised and lowered at a predetermined distance above the support plates 12.

[0028] Material support assembly 2 is set on the upper surface of workbench 11. Material support assembly 2 includes placement pad 21 and honeycomb plate 22 adapted to placement pad 21. Placement pad 21 is installed on the upper surface of honeycomb plate 22. Placement pad 21 is set as high temperature resistant blanket.

[0029] The moisture absorption component 3 includes multiple fans 31 and multiple sets of air plates 32. Each set of air plates 32 is arranged parallel to each other on the support plate 12, and the axial direction of the air plate 32 is perpendicular to the axial direction of the support plate 12. The honeycomb plate 22 is installed on the upper surface of the air plate 32. Each air plate 32 has multiple spaced air holes 321. The fans 31 are fixedly installed below the multiple air plates 32, and the air intake area of ​​the fans 31 covers or faces the air holes 321. The fans 31 are separated from the upper surface of the workbench 11 by a predetermined distance.

[0030] In this embodiment, when in use, the worker lays the fabric to be treated flat on the placement pad 21; the fan 31, after being started, draws air downward to form a negative pressure. At the same time, the honeycomb plate 22 and the air holes 321 on the fan plate 32 form an airflow channel, so that the water vapor formed after the moisture inside the fabric on the placement pad 21 evaporates is discharged downward through the honeycomb plate 22 and the air holes 321, thereby improving the dehumidification efficiency.

[0031] Specifically, the support plate 12 is provided with a pair, and the main body 1 of the device also includes a pair of slide rods 13 and two sets of fixing blocks 14. Each set of fixing blocks 14 is provided with at least one, and the fixing blocks 14 are fixedly installed on the upper end face of the workbench 11. The fixing blocks 14 have a sliding groove 141, and the slide rods 13 are slidably inserted into the sliding groove 141. Each slide rod 13 is installed on the lower end face of each support plate 12, and the axial direction of each slide rod 13 is parallel to the axial direction of each support plate 12.

[0032] In this embodiment, after the fabric cools down to room temperature, the worker pulls the support plate 12 so that the slide bar 13 slides in the slide groove 141, so that the placement pad 21 and the fabric move in a direction away from the direct under the upper pressure plate. Finally, the worker can remove the fabric from the placement pad 21.

[0033] Specifically, the material support assembly 2 also includes a metal frame 23, with the honeycomb panel 22 disposed inside the metal frame 23, and the outer wall of the honeycomb panel 22 fitting against the inner wall of the metal frame 23.

[0034] In this embodiment, the rigid support of the metal frame 23 restricts the deformation of the honeycomb panel 22, ensuring that the honeycomb panel 22 remains flat during the heat pressing process and avoiding uneven stress on the fabric due to deformation of the honeycomb panel 22.

[0035] Specifically, the main body 1 of the device also includes a pair of connecting plates 15. The cross-section of the connecting plate 15 is T-shaped. The end face of the connecting plate 15 with a larger cross-sectional area is installed on the lower end face of the support plate 12, and the end face of the connecting plate 15 with a smaller cross-sectional area is installed on the side wall of the slide rod 13. The upper end of the fixing block 14 has a snap-fit ​​groove 142 that communicates with the slide groove 141, and the lower end of the connecting plate 15 is snapped into the snap-fit ​​groove 142.

[0036] In this embodiment, by providing a connecting plate 15, the support plate 12 and the slide rod 13 are more firmly fixed.

[0037] Specifically, the size of the honeycomb panel 22 is set to 40*40cm or 40*60cm, and the size of the pad 21 is the same as that of the honeycomb panel 22;

[0038] In this embodiment, the honeycomb panel 22 and the placement pad 21 precisely cover the maximum printing area commonly found by DTG printers, avoiding any areas of the fabric that are not processed.

[0039] Specifically, each support plate 12 has multiple spaced gaskets 121 on its upper surface, and the gaskets 121 are fixedly connected to the honeycomb plate 22 by bolts.

[0040] The working principle of this utility model is as follows:

[0041] Before use, workers set the key pressing parameters of the upper pressure plate on workbench 11 according to the material of the fabric to be processed; usually, the temperature parameter is set between 120 and 200°C to avoid thermal shrinkage of the fabric, and the pressure parameter is set at 3 kgf / cm². 2 To ensure a flattening effect without damaging the fabric, the time parameter is set to around 20 seconds to ensure sufficient dehumidification without damaging the fabric fibers.

[0042] When using it, the worker lays the fabric to be treated flat on the placement pad 21 to ensure that the subsequent heat pressing area and DTG printing area are completely aligned to avoid the fabric shifting after pretreatment.

[0043] After the fan 31 is started, it draws air downward to form a negative pressure. At the same time, the honeycomb plate 22 and the air holes 321 on the fan plate 32 form an airflow channel, so that the water vapor formed after the moisture inside the fabric on the pad 21 evaporates is discharged downward through the honeycomb plate 22 and the air holes 321, thereby improving the dehumidification efficiency.

[0044] Subsequently, the upper pressure plate moves downward toward the placement pad 21 until it is in close contact with the fabric surface, eliminating the air gap between them, reducing heat loss, ensuring that the heat from the upper pressure plate is efficiently transferred to the inside of the fabric, and increasing the rate of moisture evaporation inside the fabric; at the same time, the medium and low pressure applied by the upper pressure plate is applied evenly to the fabric, which allows the loose fibers to adhere to the fibers without damaging the fabric texture, and prevents the loose fibers from detaching from the fabric surface due to their own fluffiness.

[0045] The placement pad 21, designed as a high-temperature resistant blanket, is typically woven from aramid or PBO fibers, offering high strength and low shrinkage. Furthermore, the surface of the placement pad 21 is coated with silicone or Teflon, achieving high-temperature resistance, non-stick properties, and high thermal conductivity. Its three-dimensional structure enhances abrasion resistance and uniform pressure distribution, reducing pattern color differences. Specifically, when the upper pressure plate moves down to close contact with the fabric, the placement pad 21 beneath the fabric exhibits good elasticity, causing it to deform along the fabric's contours. This ensures even heat distribution to the fabric and even pressure from the upper pressure plate to every loose lint point. Additionally, the insulation properties of the placement pad 21 maintain localized temperatures, ensuring thorough adhesion between the loose lint and fabric fibers, preventing incomplete lint removal due to insufficient localized pressure.

[0046] After the heat pressing is completed, the upper pressure plate moves away from the placement pad 21; at this time, the fan 31 continues to draw downwards to remove the heat from the heat pressing area, help the fabric cool down quickly, and avoid heat shrinkage affecting the subsequent printing size;

[0047] Once the fabric has cooled to room temperature, the worker pulls the support plate 12 to make the slide bar 13 slide in the slide groove 141, so that the placement pad 21 and the fabric move horizontally away from the direction directly below the upper pressure plate. Finally, the worker can remove the fabric from the placement pad 21.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
