Description

Technical Field

[0001] This application relates to the field of fabric drying equipment technology, and more specifically, to a digitally printed fabric drying equipment. Background Technology

[0002] After printing, printed fabrics require drying. Current technology uses heating devices to heat air and fans to circulate it, spraying the air onto the fabric for drying. However, during drying, the fabric shrinks as the temperature rises. While tensioning components are typically added during fabric transport to apply tension and stretch the fabric during drying to reduce wrinkles, the fabric width also decreases with increasing temperature. This width variation affects the overall size and quality of the fabric. Traditional drying equipment often overlooks this, failing to specifically address the width variation. Furthermore, different fabric materials shrink at different rates during drying, requiring adjustments to the stretching force based on the material. However, existing drying equipment struggles to control this stretching force effectively.

[0003] Therefore, a digitally printed fabric drying device is needed to solve the above problems. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide a digital printing fabric drying device, comprising: a frame, on which a take-up roller and an unwind roller are rotatably mounted, the take-up roller for taking up the fabric and the unwind roller for unwinding the fabric, the fabric being wound between the take-up roller and the unwind roller; a drying chamber, fixedly mounted on the frame, located between the take-up roller and the unwind roller, the drying chamber having slots for the fabric to pass through; a drying fan, fixedly mounted on the drying chamber, which introduces hot air into the drying chamber through pipes to dry the fabric; two sets of mounting plates, slidably mounted inside the drying chamber, located on both sides in the fabric width direction; a mounting frame, mounted on the underside of the mounting plates, with mounting columns fixedly connected to the mounting frame passing through the mounting plate, the mounting columns slidingly engaging with the mounting plate, a compression spring connected between the mounting frame and the mounting plate, the two ends of the compression spring being fixedly connected to the mounting frame and the mounting plate respectively; and a clamping roller, rotatably mounted on the mounting frame, which contacts the fabric to apply tension to the fabric in the width direction.

[0006] With the installation plate and clamping rollers in place, when the installation plate moves downward, it will drive the installation frame to move downward until the clamping rollers contact the fabric surface. At this time, when the clamping rollers rotate, they will apply tension to the fabric in the width direction to prevent the fabric from shrinking in the width direction when drying in the drying oven.

[0007] Furthermore, a cylinder is fixedly connected to the drying box, one end of the cylinder piston rod is fixedly connected to the mounting plate, and an adjustment groove is provided on the drying box for the mounting plate to pass through.

[0008] When the cylinder is extended, it drives the mounting plate to move downward, which in turn allows the two clamping rollers to clamp the fabric on both sides in the width direction.

[0009] Furthermore, a first rotating shaft is rotatably mounted on the mounting frame, and a meshing wheel is fixedly connected to the first rotating shaft. A rack rod is provided on the mounting frame, passing through the mounting frame and slidingly engaging with the mounting frame. The rack rod meshes with the meshing wheel. A second rotating shaft is also rotatably mounted on the mounting frame, and a clamping roller is mounted on the second rotating shaft. A synchronous pulley is fixedly connected to the first rotating shaft, and a transmission wheel is fixedly connected to the second rotating shaft. The synchronous pulley meshes with the transmission wheel. A first torsion spring is connected between the second rotating shaft and the mounting frame, and the two ends of the first torsion spring are respectively fixed to the second rotating shaft and the mounting frame.

[0010] With the first and second rotating shafts in place, when the clamping roller contacts the fabric, the cylinder continues to extend, allowing the mounting plate to contact and push the sliding block, causing the rack to move and drive the meshing wheel to rotate, which in turn causes the transmission wheel and the second rotating shaft to rotate, thereby driving the clamping roller to rotate and tension the fabric.

[0011] Furthermore, the second rotating shaft is rotatably engaged with the clamping roller, the clamping roller is sleeved on the second rotating shaft, and a second torsion spring is connected between the clamping roller and the second rotating shaft. The two ends of the second torsion spring are fixedly connected to the second rotating shaft and the clamping roller, respectively.

[0012] With the second torsion spring, when the clamping roller contacts the fabric surface and the second rotating shaft rotates, the clamping roller will have a rotational tendency under the action of the second torsion spring, thereby tensioning the fabric.

[0013] Furthermore, the upper end of the rack passes through the mounting plate, and a sliding block located on the lower side of the mounting plate is slidably connected to the rack. A positioning screw is threaded onto the sliding block, and one end of the positioning screw abuts against the rack to limit the sliding block.

[0014] By using the sliding block and positioning screw, the position of the sliding block on the rack can be adjusted, thereby controlling the distance the mounting plate pushes the sliding block to move. This allows for adjustment of the rotation angle of the second rotating shaft. When the rotation angle of the second rotating shaft is small, the tension force applied to the fabric by the clamping roller is also small. When the rotation angle of the second rotating shaft is large, the tension force applied to the fabric by the clamping roller is also large. This allows for adjustment of the tension force according to different types of fabrics.

[0015] Furthermore, a side plate located below the clamping roller is fixedly connected inside the drying chamber, and the edges of the fabric on both sides are located above the side plate. A lower side roller located below the clamping roller is rotatably connected inside the drying chamber. A through groove is provided on the side plate for the lower side roller to pass through, so that the lower side roller can cooperate with the clamping roller to clamp the fabric on both sides.

[0016] With the side plates and lower rollers in place, the fabric is positioned on the upper side of the side plates when it is in the drying chamber. The side plates support the fabric on both sides to prevent curling. At the same time, the lower rollers work in conjunction with the clamping rollers to hold the fabric in place.

[0017] Furthermore, a heater is installed at the top of the drying box to heat the gas introduced into the drying box by the drying fan, and multiple sets of through holes are opened at the bottom of the drying box.

[0018] The heater can heat the airflow to ensure the drying effect, while the through holes allow moisture to be quickly discharged.

[0019] Furthermore, the sides of the clamping rollers have anti-slip textures.

[0020] To prevent slippage between the clamping rollers and the fabric.

[0021] The beneficial effects of this application are as follows:

[0022] 1. With the installation plate and clamping rollers in place, when the installation plate moves downward, it will drive the installation frame to move downward until the clamping rollers contact the fabric surface. At this time, when the clamping rollers rotate, they will apply tension to the fabric in the width direction to prevent the fabric from shrinking in the width direction when drying in the drying oven.

[0023] 2. By using the sliding block and positioning screw, the position of the sliding block on the rack can be adjusted, thereby controlling the distance the mounting plate pushes the sliding block to move. This allows for adjustment of the rotation angle of the second rotating shaft. When the rotation angle of the second rotating shaft is small, the tension force applied to the fabric by the clamping roller is also small. When the rotation angle of the second rotating shaft is large, the tension force applied to the fabric by the clamping roller is also large. This allows for adjustment of the tension force according to different types of fabrics.

[0024] 3. With the side plates and lower rollers in place, the fabric is positioned on the upper side of the side plates when it is in the drying chamber. The side plates support the fabric on both sides to prevent curling. At the same time, the lower rollers work in conjunction with the clamping rollers to hold the fabric in place.

[0040] Reference Figure 1-5 A digital printing fabric drying device includes: a frame 10, a take-up roller 11, an unwind roller 12, a drying chamber 13, a drying fan 14, a mounting plate 18, a mounting frame 19, a mounting column 21, and a compression spring 22. The take-up roller 11 and the unwind roller 12 are distributed front-to-back and rotatably mounted on the frame 10. The take-up roller 11 is used for taking up the fabric, and the unwind roller 12 is used for unwinding it. The fabric is wound between the take-up roller 11 and the unwind roller 12. The take-up roller 11 and the unwind roller 12 can be driven by a servo motor, so that the fabric between the take-up roller 11 and the unwind roller 12 can generate tension in the length direction, similar to fabric take-up rollers and fabric unwind rollers in the prior art. The drying chamber 13 is fixedly mounted on the frame 10, located between the take-up roller 11 and the unwind roller 12. The fabric passes through the drying chamber 13, which has slots 15 for the fabric to pass through. Through the take-up and unwinding of the take-up roller 11 and the unwind roller 12, the fabric gradually passes through the drying chamber 13. A drying fan 14 is fixed on the drying chamber 13. The drying fan 14 introduces hot air into the drying chamber 13 through a pipe to dry the fabric. A heater is installed at the upper inner side to heat the air introduced into the drying chamber 13 by the drying fan 14. Multiple sets of through holes are opened at the lower end of the drying chamber 13. After being heated by the heater, the airflow is blown onto the surface of the fabric for drying, and the moisture is discharged through the through holes.

[0041] Two mounting plates 18 are located above the fabric width on both sides of the drying chamber 13. A cylinder 17 is fixedly connected to the drying chamber 13, with one end of the piston rod of the cylinder 17 fixedly connected to the mounting plate 18. An adjustment groove 16 is provided on the drying chamber 13 for the mounting plate 18 to pass through. When the cylinder 17 extends, it will drive the mounting plate 18 to move downward. A mounting frame 19 is provided on the lower side of the mounting plate 18. A mounting post 21 passing through the mounting plate 18 is fixedly connected to the mounting frame 19. The mounting post 21 is slidably engaged with the mounting plate 18, and two sets of mounting posts 21 are provided. A compression spring 22 is provided between the mounting frame 19 and the mounting plate 18, with both ends of the compression spring 22 fixedly connected to the mounting frame 19 and the mounting plate 18, respectively. When the mounting plate 18 moves downward, it drives the mounting frame 19 to move downward. A first rotating shaft 24 and a second rotating shaft 27 are rotatably mounted on the mounting frame 19. The second rotating shaft 27 is located below the first rotating shaft 24, and a clamping roller 20 that rotatably engages with the second rotating shaft 27 is sleeved on the second rotating shaft 27. When the mounting frame 19 moves downward, it drives the clamping roller 20 downward, which then contacts the upper side of the fabric. A side plate 33 located below the clamping roller 20 is fixedly connected inside the drying chamber 13. The two edges of the fabric are located above the side plate 33. A lower side roller 34 located below the clamping roller 20 is rotatably connected inside the drying chamber 13. A through groove 35 is provided on the side plate 33 for the lower side roller 34 to pass through, so that the lower side roller 34 can cooperate with the clamping roller 20 to clamp the two sides of the fabric. When the fabric is inside the drying chamber 13, the two sides of the fabric are located above the side plate 33. The side plate 33 supports the two sides of the fabric to prevent curling. At the same time, the lower side roller 34 can cooperate with the clamping roller 20 to clamp the fabric.

[0042] A meshing wheel 25 is fixedly connected to the first rotating shaft 24. A rack 23 is provided on the mounting frame 19, which passes through the mounting frame 19 and slides in cooperation with the mounting frame 19. The rack 23 meshes with the meshing wheel 25.

[0043] A synchronous pulley 26 is fixedly connected to the first rotating shaft 24, and a transmission pulley 28 is fixedly connected to the second rotating shaft 27. The synchronous pulley 26 and the transmission pulley 28 mesh. A first torsion spring 31 is connected between the second rotating shaft 27 and the mounting frame 19, with both ends of the first torsion spring 31 fixed to the second rotating shaft 27 and the mounting frame 19, respectively. A second torsion spring 32 is connected between the clamping roller 20 and the second rotating shaft 27, with both ends of the second torsion spring 32 fixedly connected to the second rotating shaft 27 and the clamping roller 20, respectively.

[0044] The upper end of the rack 23 passes through the mounting plate 18. A sliding block 29 located below the mounting plate 18 is slidably connected to the rack 23. A positioning screw 30 is threaded onto the sliding block 29, with one end of the positioning screw 30 abutting against the rack 23 to limit the sliding block 29. The position of the sliding block 29 on the rack 23 can be adjusted, thereby controlling the distance the mounting plate 18 pushes the sliding block 29 to move. This allows adjustment of the rotation angle of the second rotating shaft 27. When the rotation angle of the second rotating shaft 27 is small, the tension force applied to the fabric by the clamping roller 20 is also small; when the rotation angle of the second rotating shaft 27 is large, the tension force applied to the fabric by the clamping roller 20 is also large. This allows for adjustment of the tension force according to different types of fabrics.

[0045] Working process or usage method:

[0046] 1. During drying, the fabric is inside the drying chamber 13. The drying fan 14, in conjunction with the heater, dries the fabric. To prevent shrinkage in the width direction, tension is applied. This is achieved by extending the control cylinder 17, causing the mounting plate 18 to move downwards, which in turn moves the mounting frame 19 downwards until the clamping roller 20 contacts the fabric surface. The mounting plate 18 continues to move downwards, contacting and pushing the sliding block 29, causing the rack 23 to move and rotating the meshing wheel 25. This causes the transmission wheel 28 and the second rotating shaft 27 to rotate. Under the action of the second torsion spring 32, the clamping roller 20 has a rotational tendency, cooperating with the lower roller 34 to tension the fabric until the mounting plate 18 reaches its lowest point.

[0047] 2. After drying is completed, the cylinder 17 is controlled to return to the initial state. At this time, the take-up roller 11 and the unwind roller 12 are controlled to transport the next part of the fabric into the drying box 13 for continued drying.

[0048] 3. When it is necessary to adjust the tension according to the fabric material, the position of the sliding block 29 on the rack 23 is adjusted, thereby controlling the distance that the mounting plate 18 pushes the sliding block 29 to move. This allows for adjustment of the rotation angle of the second rotating shaft 27. When the rotation angle of the second rotating shaft 27 is small, the tension applied to the fabric by the clamping roller 20 is also small. When the rotation angle of the second rotating shaft 27 is large, the tension applied to the fabric by the clamping roller 20 is also large. This allows for adjustment of the tension according to different types of fabrics.
