Description

Technical Field

[0001] This invention relates to the field of fabric printing and dyeing, and more specifically, to a textile fabric printing and dyeing process and a device for maintaining the flatness of printed and dyed fabrics. Background Technology

[0002] After dyeing and printing, textile fabrics typically require a fabric smoothing and holding device to flatten the fabric surface, making it smoother. The flattened fabric is then rolled up for later processing. This fabric smoothing device is used for finishing dyed and printed fabrics. It effectively processes the fabric, usually using a motor-driven pressing block to flatten and shape it, increasing efficiency during the shaping process. Additionally, a dust collection box can be installed at the rear of the device to effectively remove dust from the fabric, ensuring that fine dust particles do not affect the fabric's quality.

[0003] After the textile fabric is printed and dyed, it usually needs to be manually installed on the conveyor rollers in the printed and dyed fabric flattening and holding device. However, manual operation leads to low installation efficiency. Summary of the Invention

Mix the dyeing solution thoroughly and adjust the pH value of the dyeing solution to the range of 4-6. Keep the dye temperature stable and control the dyeing temperature in the dyeing machine at 85-96℃. The dyeing time is 52-62 minutes. Then, transport the rinsed textile fabric to the dyeing machine for dyeing. During the dyeing process, position the textile fabric in its flat state.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. Place the end of the printed and dyed textile fabric between two clamping arms. The fifth motor drives the third threaded rod to rotate. At this time, the connecting block slides along the inner wall of the mounting groove. The connecting block drives the connecting plate to move. The connecting plate pushes the two sliding shafts to slide along the inner wall of the second sliding groove on the clamping arm. When the sliding shafts slide to the end of the second sliding groove, the upper clamping arm drives the second fixed shaft to rotate under the torsion of the torsion spring. The second fixed shaft drives the first fixed shaft to rotate through the gear, thereby causing the two clamping arms to close and clamp and fix the end of the printed and dyed textile fabric. The third motor drives the second threaded rod to rotate, causing the slider to drive the fourth motor to move. At the same time, it can drive the mounting frame to move, so that the end of the textile fabric can move horizontally, allowing the fabric to pass between the two rubber sleeves and between the second roller sleeve and the first roller sleeve. This design makes it easy for operators to quickly install the fabric on the conveyor roller in the printed and dyed fabric flattening and holding device, improving the installation speed.

[0023] 2. The first threaded rod is driven to rotate by two second motors, and the upper bushing slides down along the guide rod. At this time, the two rubber sleeves can clamp and fix the fabric. The sliding seat is pushed down along the slide rod by the hydraulic rod. The sliding seat drives the second rotating shaft to slide down along the sliding hole. At this time, the second roller sleeve presses the fabric onto the two first roller sleeves. This design can quickly fix the installed fabric and transport the fabric.

[0024] 3. Under the stretching of the fabric, the two rubber sleeves at both ends of the fabric are driven by electric rollers to move the slide plates, so that the slide plates can slide along the connecting rod. At this time, the spring provides a reaction force, so that the textile fabric is in a taut state. Steam is sprayed upward through the steam nozzle, and the fabric is humidified and heated by the hot steam. Since the fabric between the two first roller sleeves is in a taut state, the fabric can be flattened. At the same time, the second roller sleeve presses the fabric on the two first roller sleeves, squeezing the fabric flat.

[0025] 4. Two electric rollers drive the upper and lower rubber sleeves to rotate, so that the upper and lower rubber sleeves rotate synchronously in opposite directions, which can clamp and transport the fabric, making the fabric move smoothly. Attached Figure Description

[0038] A textile fabric printing and dyeing process includes the following steps:

[0039] S1. Singeing treatment: The textile fabric to be dyed is fed into the singeing machine for singeing. The singeing temperature of the singeing machine is controlled at 390-420℃.

[0040] S2. Soaking and washing: The singed fabric is immersed in a bleaching tank containing hydrogen peroxide bleaching solution for soaking and rinsing. The pH value of the hydrogen peroxide bleaching solution is adjusted between 8 and 10, and the concentration of the hydrogen peroxide bleaching solution is adjusted between 4.5 and 5.5 g / L. Then it is cleaned with deionized water.

[0041] S3. Dyeing: Add water, water-soluble dye, and surfactant to the dyeing machine in advance, and then add an appropriate amount of retarder to form a dyeing solution. Mix the dyeing solution thoroughly and adjust the pH value of the dyeing solution to the range of 4-6.

A hydraulic rod 109 is fixed on the top of the upper fixed block 108. The output end of the hydraulic rod 109 passes through the fixed block 108 and extends to its lower part. The ends of the two sliding rods 110 pass through the sliding seat 111 and are slidably connected to it. The output end of the hydraulic rod 109 is connected and fixed to the top of the sliding seat 111. A first motor 112 is fixed on the top of the sliding seat 111. The output end of the first motor 112 passes through the sliding seat 111 and is connected and fixed to the second rotating shaft 106.

[0047] like Figure 4 and Figure 5 As shown, the conveying assembly 2 includes a second bracket 201, which is connected and fixed to the first bracket 101. A first groove 202 is formed on the outer wall of the second bracket 201. A connecting rod 203 is fixed to the inner wall of the first groove 202. A spring 204 is sleeved on the outer circumference of the connecting rod 203. A sliding plate 205 is slidably connected to the inner wall of the first groove 202.

The output end of 212 is connected and fixed to the first threaded rod 211. Two bushings 209 are sleeved through the inner wall of the slide plate 205. The upper bushing 209 passes through the adjustment hole 206 and is slidably connected to its inner wall.

[0048] In this embodiment, two second motors 212 drive the corresponding first threaded rods 211 to rotate, and the upper bushing 209 slides down along the guide rod 207. At this time, the two rubber sleeves 213 can clamp and fix the fabric. The hydraulic rod 109 pushes the sliding seat 111 to slide down along the slide rod 110. The sliding seat 111 drives the second rotating shaft 106 to slide down along the sliding hole 103. At this time, the second roller sleeve 107 presses the fabric onto the two first roller sleeves 105. This design can quickly fix the installed fabric and transport the fabric.

[0049] Under the tension of the fabric, the two rubber sleeves 213 at both ends of the fabric drive the slide plate 205 to move via the electric roller 208, so that the slide plate 205 can slide along the connecting rod 203. At this time, the spring 204 provides a reaction force, so that the textile fabric is in a taut state. Steam is sprayed upward through the steam nozzle 102, and the fabric is humidified and heated by the hot steam. Since the fabric between the two first roller sleeves 105 is in a taut state, the fabric can be flattened. At the same time, the second roller sleeve 107 presses the fabric on the two first roller sleeves 105, squeezing the fabric flat.

[0050] like Figure 6 As shown, the drive assembly 3 includes a guide seat 301. The bottom of the guide seat 301 is connected and fixed to the first bracket 101 and the second bracket 201 respectively. A moving groove 302 is provided on the top of the guide seat 301.

[0051] like Figure 7 , Figure 8 and Figure 9As shown, the clamping assembly 4 includes a mounting frame 401. A mounting groove 402 is formed on the outer wall of the mounting frame 401. A third threaded rod 406 is rotatably connected to the inner wall of the mounting groove 402.

A first fixed shaft 407 and a second fixed shaft 409 are rotatably connected to the inner wall of the mounting frame 401. Each of the nine ends is fixed with a clamping arm 412. The outer circumferential walls of the first fixed shaft 407 and the second fixed shaft 409 are both fixed with gears 408, which mesh with each other. The outer circumferential wall of the second fixed shaft 409 is fitted with a torsion spring 411. The end of the second fixed shaft 409 is fixed with a limiting sleeve 410. The outer walls of the two clamping arms 412 are each provided with a second sliding groove 414, which can be inclined on the clamping arms 412. The outer wall of the connecting plate 413 is symmetrically structured with two sliding shafts 415.

One end of the torsion spring 411 is connected and fixed to the limiting sleeve 410, and the other end of the torsion spring 411 is connected and fixed to the mounting frame 401.

[0052] The dyed textile fabric is placed between two clamping arms 412. The fifth motor 404 drives the third threaded rod 406 to rotate. At this time, the connecting block 405 slides along the inner wall of the mounting groove 402. The connecting block 405 drives the connecting plate 413 to move. The connecting plate 413 pushes the two sliding shafts 415 to slide along the inner wall of the second sliding groove 414 on the clamping arm 412. When the sliding shafts 415 slide towards the end of the second sliding groove 414, the upper clamping arm 412, under the torque of the torsion spring 411, drives the second fixed shaft 409 to rotate. The second fixed shaft 409 is driven by the gear 408. The first fixed shaft 407 rotates, causing the two clamping arms 412 to close and clamp and fix the end of the printed and dyed textile fabric. The third motor 304 drives the second threaded rod 303 to rotate, causing the slider 305 to drive the fourth motor 306 to move. At the same time, it can drive the mounting frame 401 to move, so that the end of the textile fabric can move horizontally and pass between the two rubber sleeves 213 and between the second roller sleeve 107 and the first roller sleeve 105. This design makes it easy for operators to quickly install the fabric on the conveyor roller in the printed and dyed fabric flattening and holding device, improving the installation speed.

[0053] Working principle: The end of the printed and dyed textile fabric is placed between two clamping arms 412. The fifth motor 404 drives the third threaded rod 406 to rotate. At this time, the connecting block 405 slides along the inner wall of the mounting groove 402. The connecting block 405 drives the connecting plate 413 to move. The connecting plate 413 pushes the two sliding shafts 415 to slide along the inner wall of the second sliding groove 414 on the clamping arm 412. When the sliding shaft 415 slides towards the end of the second sliding groove 414, the upper clamping arm 412 drives the second fixed shaft 409 to rotate under the torque of the torsion spring 411. The second fixed shaft 409 drives the first fixed shaft 407 to rotate through the gear 408, thereby causing the two clamping arms 412 to close and clamp and fix the end of the printed and dyed textile fabric.

[0054] The third motor 304 drives the second threaded rod 303 to rotate, which causes the slider 305 to drive the fourth motor 306 to move, and at the same time can drive the mounting frame 401 to move, so that the end of the textile fabric can move horizontally, and the fabric passes between the two rubber sleeves 213 and between the second roller sleeve 107 and the first roller sleeve 105.

[0055] By removing the fabric end from the two clamping arms 412, the fourth motor 306 drives the mounting frame 401 to rotate to the outer side, and the third motor 304 drives the slider 305 to move in the opposite direction to the fabric feeding end.

[0056] Two second motors 212 drive the corresponding first threaded rods 211 to rotate, and the upper bushing 209 slides down along the guide rod 207. At this time, the two rubber sleeves 213 can clamp and fix the fabric.

[0057] The hydraulic rod 109 pushes the sliding seat 111 to slide down along the sliding rod 110, and the sliding seat 111 drives the second rotating shaft 106 to slide down along the sliding hole 103. At this time, the second roller sleeve 107 presses the fabric onto the two first roller sleeves 105.

[0058] Under the stretching of the fabric, the two rubber sleeves 213 at both ends of the fabric drive the slide plate 205 to move through the electric roller 208, so that the slide plate 205 can slide along the connecting rod 203. At this time, the spring 204 provides a reaction force, so that the textile fabric is in a taut state. Steam is sprayed upward through the steam nozzle 102, and the fabric is humidified and heated by the hot steam. Since the fabric between the two first roller sleeves 105 is in a taut state, the fabric can be flattened. At the same time, the second roller sleeve 107 presses the fabric on the two first roller sleeves 105, squeezing the fabric flat.

[0059] The first motor 112 drives the second rotating shaft 106 to rotate, the second rotating shaft 106 drives the second roller sleeve 107 to rotate, and the second roller sleeve 107 drives the two first roller sleeves 105 to rotate, which can transport the fabric.

[0060] At the same time, the two electric rollers 208 drive the upper and lower rubber sleeves 213 to rotate, so that the upper and lower rubber sleeves 213 rotate synchronously in opposite directions, which can clamp and transport the fabric, making the fabric move smoothly.
