Description

Technical Field

[0001] This invention relates to the field of fabric drying technology, specifically to a uniform drying device for fabric printing and dyeing. Background Technology

[0002] The main function of drying equipment for fabric printing and dyeing is to quickly and evenly remove moisture from the fabric after the printing and dyeing process, avoiding problems such as color difference, bubbling, or deformation, ensuring stable fabric quality, and facilitating subsequent processing or finished product production. However, existing fabric printing and dyeing drying equipment has the following problems in use:

[0003] Existing fabric printing and dyeing drying equipment typically features a fixed air duct design, allowing for adjustment of the drying environment solely through overall heating or cooling. When overheating occurs inside the equipment, these systems generally lack a direct cooling air duct switching mechanism, often relying solely on the overall temperature control system for gradual cooling. This results in a lag in response and hinders rapid relief of overheating issues. Prolonged high temperatures can lead to fading, scorching, and even fabric deformation, negatively impacting printing and dyeing quality. This makes them unsuitable for drying high-quality fabrics. Furthermore, the existing equipment's accompanying pressing and straightening systems... Most pressure structures employ a constant pressure design, which is inconvenient to adjust according to fabric thickness. For fabrics that have been dyed and are about to be dried, they need to be gently pressed to keep the fabric flat in order to ensure uniformity in subsequent drying. However, when adapting to fabrics of different thicknesses, the constant pressure structure may not be suitable for thicker fabrics. Insufficient pressure will not be able to smooth out wrinkles, and heat will not be able to penetrate the wrinkles, which may cause uneven drying in some areas. For thinner fabrics, excessive pressure will cause the fabric to stretch and deform, which will also affect the flatness and quality of the fabric after drying. It is difficult to meet the processing requirements of achieving uniform drying by gently pressing and smoothing fabrics of different thicknesses.

[0004] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

[0009] A heat dissipation assembly is disposed between the drying chamber and the fan shroud for internal heat dissipation of the fan shroud;

[0010] An air outlet mechanism is installed on the top outer side of the base;

[0011] The force-applying component includes a first magnet, which is fixed to the outside of the mounting column. A second magnet is correspondingly provided on the outside of the first magnet. The second magnet is fixed to the inside of the force-applying rod. The force-applying rod is laterally limited by a spring and is located in the cavity of the mounting plate. A force-applying block is correspondingly provided at the outer end of the force-applying rod. The force-applying block is installed on the inner wall of the drying oven.

[0012] The first magnet and the second magnet repel each other magnetically. The force-applying rod slides laterally against the cavity of the mounting plate. The inner end face of the force-applying block is designed as an inclined surface. The outer end of the force-applying rod slides against the inclined surface of the force-applying block.

[0013] Preferably, the upper and lower mounting plates move in opposite directions, the mounting columns slide vertically into the cavities of the mounting plates, the pressure rollers are evenly distributed in the drying chamber, and the distance between the pressure rollers and the fabric decreases sequentially from right to left.

[0014] Preferably, the interior of the hood is provided with a partition in the longitudinal direction, and heating wires are fixed between the two sides of the partition and the inner wall of the hood.

[0015] Preferably, the first baffle and the second baffle, together with the partition, divide the hood into two air outlet areas, and the first baffle and the second baffle inside the upper and lower hoods are staggered.

[0016] Preferably, the transmission assembly includes a first toothed roller and a second toothed roller. The first toothed roller and the second toothed roller are embedded in the interior of the partition via a dual-axis motor. A first rack and a second rack are respectively meshed on the outer sides of the first toothed roller and the second toothed roller. The first rack is fixed to the inner side of the first baffle, and the second rack is fixed to the inner side of the second baffle.

[0017] Preferably, the heat dissipation assembly includes a heat insulation pipe, which is disposed through the drying chamber and the fan hood. A heat dissipation fin is installed inside the heat insulation pipe. A second elastic telescopic rod is provided at the protrusions on both sides of the inner wall of the heat insulation pipe and the protrusions on both sides of the heat dissipation fin. An inclined groove is opened at the inner end of the heat dissipation fin. A transmission rod is abutted in the inclined groove of the heat dissipation fin.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention utilizes the linkage of an electric push rod and a repulsive structure between a first magnet and a second magnet to ensure that thicker fabrics receive relatively higher pressure from the pressure rollers, while thinner fabrics receive relatively lower pressure. Furthermore, the pressure rollers decrease sequentially from right to left, adapting to the gradual decrease in moisture content during the fabric drying process. This not only prevents wrinkles from remaining on thicker fabrics due to insufficient pressure but also prevents stretching and deformation of thinner fabrics due to excessive pressure, thereby improving the overall smoothness of the fabric and enhancing the uniformity of drying.

[0022] In this invention, when the temperature sensor inside the drying oven detects overheating, a dual-axis motor drives the first toothed roller to mesh with the first toothed rack and the second toothed roller to mesh with the second toothed rack, simultaneously moving the first and second baffles to switch the air outlets. Furthermore, the first and second baffles within the upper and lower air hoods are staggered, preventing the adverse effects of vertical airflow convection on the drying effect. Simultaneously, the movement of the first baffle triggers the staggered extension and retraction of the heat sink, opening the heat insulation plates to rapidly dissipate heat from the overheated area. This effectively reduces the probability of fabric fading, scorching, and deformation due to high temperatures, ensuring the stability of the printed and dyed product quality and meeting the high-quality drying needs of fabrics of different specifications.

[0032] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.

[0033] Please see Figures 1-8 The present invention provides a technical solution: a uniform drying device for fabric printing and dyeing, including a base 1, with take-up and release rollers arranged on the top left and right sides of the base 1, and a drying box 2 suspended and fixed on the top of the base 1, with the drying box 2 arranged in the middle of the take-up and release rollers.

[0034] Manually pull the printed fabric to be dried from the unwinding roller on the right side of the base 1, pass it through the tension roller and the pressure roller 7 in the drying box 2 in sequence to complete the path layout of the fabric, let this section of fabric dry, and then fix it to the winding roller on the left side of the base 1.

[0035] In one embodiment of the present invention, electric push rods 3 are installed on the upper and lower corresponding protrusions of the front and rear inner walls of the drying oven 2. The output end of the electric push rod 3 is connected to the mounting plate 4. The mounting plate 4 has a mounting column 6 connected to the cavity side wall through a first elastic telescopic rod 5. The inner end of the mounting column 6 is rotatably mounted with a pressure roller 7 through a bearing. A force application component is provided between the mounting plate 4 and the mounting column 6.

[0036] The upper and lower mounting plates 4 move in opposite directions, the mounting columns 6 slide vertically into the cavity of the mounting plates 4, and the pressure rollers 7 are evenly distributed in the drying box 2. The distance between the pressure rollers 7 and the fabric decreases from right to left.

[0037] The force-applying component includes a first magnet 81, which is fixed to the outside of the mounting column 6. A second magnet 82 is correspondingly provided on the outside of the first magnet 81. The second magnet 82 is fixed to the inside of the force-applying rod 83. The force-applying rod 83 is laterally limited by a spring and is set in the cavity of the mounting plate 4. A force-applying block 84 is correspondingly provided on the outer end of the force-applying rod 83. The force-applying block 84 is installed on the inner wall of the drying oven 2. The magnetism of the first magnet 81 and the second magnet 82 repels each other, and the force-applying rod 83 slides laterally in contact with the cavity of the mounting plate 4. The inner end face of the force-applying block 84 is designed as a slope, and the outer end of the force-applying rod 83 slides in contact with the slope of the force-applying block 84.

[0038] To address the pressing requirements of fabrics of varying thicknesses, pressure adjustment is achieved by regulating the linkage between the electric push rod 3 and the repulsive structure of the first magnet 81 and the second magnet 82. When processing thicker fabrics, the electric push rod 3 pushes the mounting plate 4 outwards, causing the outer end of the force rod 83 to adhere to the inclined surface of the force block 84, which in turn drives it inwards. This increases the overlap area between the second magnet 82 and the first magnet 81, increasing the repulsive force. The pressure roller 7 then moves to a height suitable for the thicker fabric. Under the repulsive force of the magnets, the pressure applied to the fabric by the pressure roller 7 increases accordingly, helping to press out internal moisture. When processing thinner fabrics, after adjusting the electric push rod 3, the mounting plate 4 moves inwards. Under the force of the spring, the outer end of the force rod 83 adheres to the inclined surface of the force block 84, causing the force rod 83 to move outwards. The overlap area between the second magnet 82 and the first magnet 81 is smaller, weakening the repulsive force. Under the repulsive force of the magnets, the pressure applied to the fabric by the pressure roller 7 decreases, preventing most of the moisture from being pressed out of the fabric at the beginning.

[0039] In one embodiment of the present invention, the upper and lower end faces of the drying oven 2 are respectively connected by an external air duct through an air supply pipe 9. An air hood 10 is installed at the inner end of the air supply pipe 9. A first baffle 11 is slidably arranged at the air inlet of the air hood 10, and a second baffle 12 is slidably arranged at the air outlet of the air hood 10. A partition 101 is longitudinally arranged inside the air hood 10, and heating wires 102 are fixed between the two sides of the partition 101 and the inner side wall of the air hood 10.

[0040] A transmission assembly is disposed between the hood 10 and the partition 101 to switch the positions of the first baffle 11 and the second baffle 12. The first baffle 11 and the second baffle 12, together with the partition 101, divide the hood 10 into two air outlet areas. The first baffle 11 and the second baffle 12 are staggered in the upper and lower hoods 10. The transmission assembly includes a first toothed roller 131 and a second toothed roller 132. The first toothed roller 131 and the second toothed roller 132 are embedded in the partition 101 by a dual-axis motor. The outer sides of the first toothed roller 131 and the second toothed roller 132 are respectively meshed with a first rack 133 and a second rack 134. The first rack 133 is fixed to the inner side of the first baffle 11, and the second rack 134 is fixed to the inner side of the second baffle 12. The air outlet mechanism 15 is installed on the top outer side of the base 1.

[0041] The air from the external air duct of the drying oven 2 is delivered from the air supply pipe 9 to the upper and lower air hoods 10. The air hoods 10 are divided into two independent areas by the partition 101. The air is heated by the electric heating wire 102 in the air hoods 10 to form hot air, which is then blown onto the surface of the fabric. At the same time, the first baffle 11 and the second baffle 12 in the upper and lower air hoods 10 are staggered and can be opened alternately, so that the hot air acts evenly on both sides of the fabric and avoids mutual interference between the upper and lower hot air. The hot air from the upper and lower air hoods 10 works together to dry the fabric evenly.

[0042] During the drying process, the built-in temperature sensor in the hood 10 monitors the temperature inside the hood 10 in real time. When an over-temperature condition is detected, the dual-axis motor is activated. The dual-axis motor drives the first toothed roller 131 and the second toothed roller 132 to rotate synchronously. Through the transmission action of the first toothed roller 131 meshing with the first rack 133 and the second toothed roller 132 meshing with the second rack 134, the first baffle 11 and the second baffle 12 are moved to achieve rapid switching of the air outlet. Since the first baffle 11 and the second baffle 12 inside the upper and lower hood 10 are staggered, the upper and lower air convection is always avoided during the switching process to ensure the drying stability. Finally, the hot air inside is extracted by the air outlet mechanism 15.

[0043] In one embodiment of the present invention, a heat dissipation assembly is disposed between the drying chamber 2 and the fan shroud 10 for internal heat dissipation of the fan shroud 10. The heat dissipation assembly includes a heat insulation pipe 141, which is disposed through the drying chamber 2 and the fan shroud 10. A heat dissipation fin 142 is installed inside the heat insulation pipe 141. A second elastic telescopic rod 143 is provided at the protrusions on both sides of the inner wall of the heat insulation pipe 141 and the protrusions on both sides of the heat dissipation fin 142. An inclined groove is opened at the inner end of the heat dissipation fin 142. A transmission rod 144 is abutted in the inclined groove of the heat dissipation fin 142. A push block 145 is correspondingly provided at the outer end of the transmission rod 144. The push block 145 is fixed at both ends of the first baffle 11. A heat insulation plate 146 is installed opposite to the inner end of the heat insulation pipe 141 through a torsion spring.

[0044] The heat insulation pipes 141 are symmetrically distributed about the fan cover 10. The heat insulation plates 146 are staggered inside the fan cover 10. The heat sink 142 moves obliquely inside the heat insulation pipes 141 along the installation position of the heat insulation pipes 141. The transmission rod 144 is embedded and slidably disposed inside the fan cover 10. The inner end of the transmission rod 144 is designed as a slope, and the slope of the transmission rod 144 corresponds to the inclined groove of the inner end of the heat sink 142.

[0045] When the first baffle 11 moves to the other side of the air vent, the push block 145 at its end abuts against the transmission rod 144, pushing the transmission rod 144 to move obliquely along the inside of the shroud 10, so that the inner end of the transmission rod 144 is in contact with the inclined groove of the heat sink 142, thereby pushing the heat sink 142 to extend outward along the heat insulation tube 141. During the extension of the heat sink 142, the heat insulation plate 146 is opened simultaneously to achieve heat dissipation in the overheated area. At the same time, inside the heat insulation tube 141 on the other side of the shroud 10, because the push block 145 is separated from the transmission rod 144, the transmission rod 144 loses the external force. Under the reset action of the second elastic telescopic rod 143, the heat sink 142 retracts into the heat insulation tube 141, and the heat insulation plate 146 closes under the action of the torsion spring, completing the overheating heat dissipation operation.

[0046] Working principle: First, manually pull the printed and dyed fabric to be dried from the unwinding roller on the right side of the base 1, pass it through the tension roller and the pressure roller 7 in the drying box 2 in sequence to complete the path layout of the fabric, dry this section of fabric at rest, and then fix it to the winding roller on the left side of the base 1.

[0047] To address the pressing requirements of fabrics of varying thicknesses, pressure adjustment is achieved by regulating the linkage between the electric push rod 3 and the repulsive structure of the first magnet 81 and the second magnet 82. When processing thicker fabrics, the electric push rod 3 pushes the mounting plate 4 outwards, causing the outer end of the force application rod 83 to contact the inclined surface of the force application block 84, thus influencing its inward movement. This increases the overlap area between the second magnet 82 and the first magnet 81, allowing the pressure roller 7 to move to a height suitable for the thicker fabric. Under the repulsive effect of the magnets, the pressure applied to the fabric by the pressure roller 7 increases accordingly, helping to squeeze out internal moisture. When processing thinner fabrics, the electric push rod 3 is adjusted... After rod 3, mounting plate 4 moves inward and opposite to each other. Under the action of spring, the outer end of force rod 83 is attached to the inclined surface of force block 84, so that force rod 83 moves outward. The overlapping area of ​​second magnet 82 and first magnet 81 is small, and the repulsive force is weakened. Under the magnetic repulsive action, the pressure applied to the fabric by pressure roller 7 is reduced, avoiding pressing out most of the moisture from the fabric at the beginning. In addition, the distance between pressure roller 7 and fabric in drying box 2 decreases from right to left, so that the pressure of pressure roller 7 on fabric is distributed from right to left, which is suitable for the characteristic of the gradual decrease of moisture content during the drying process of fabric.

[0048] The air from the external air duct of the drying oven 2 is delivered from the air supply pipe 9 to the upper and lower air hoods 10. The air hoods 10 are divided into two independent areas by the partition 101. The air is heated by the electric heating wire 102 in the air hoods 10 to form hot air, which is then blown onto the surface of the fabric. At the same time, the first baffle 11 and the second baffle 12 in the upper and lower air hoods 10 are staggered and can be opened alternately, so that the hot air acts evenly on both sides of the fabric and avoids mutual interference between the upper and lower hot air. The hot air from the upper and lower air hoods 10 works together to dry the fabric evenly.

[0049] During the drying process, the built-in temperature sensor in the hood 10 monitors the temperature inside the hood 10 in real time. When an over-temperature condition is detected, the dual-axis motor is activated. The dual-axis motor drives the first toothed roller 131 and the second toothed roller 132 to rotate synchronously. Through the transmission action of the first toothed roller 131 meshing with the first rack 133 and the second toothed roller 132 meshing with the second rack 134, the first baffle 11 and the second baffle 12 are moved, realizing the rapid switching of the air outlet. Since the first baffle 11 and the second baffle 12 inside the upper and lower hoods 10 are staggered, the upper and lower air convection is always avoided during the switching process, ensuring the drying stability. At the same time, when the first baffle 11 moves to the other side of the air outlet, the push block 145 at its end abuts against the transmission rod 144, pushing the transmission rod 144 to move inclined along the inside of the hood 10, so that the inner end of the transmission rod 144 is inclined. The inclined groove of the heat sink 142 is aligned with the heat sink 142, which in turn pushes the heat sink 142 to extend outward along the heat insulation tube 141. During the extension of the heat sink 142, the heat insulation plate 146 is opened simultaneously to achieve heat dissipation in the overheated area. At the same time, in the heat insulation tube 141 on the other side of the fan cover 10, the push block 145 is separated from the transmission rod 144, and the transmission rod 144 loses its external force. Under the reset action of the second elastic telescopic rod 143, the heat sink 142 retracts into the heat insulation tube 141, and the heat insulation plate 146 closes under the action of the torsion spring, completing the overheating heat dissipation operation. After the corresponding area of ​​the fabric is dried, the take-up roller is rotated to collect the dried fabric. The above process is repeated to complete the drying process of the remaining fabric. Finally, the internal hot air is extracted by the air outlet mechanism 15, which consists of a fan and a filter screen to draw in and filter the internal air.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
