Description

Technical Field

[0001] The invention belongs to the technical field of cashmere fabric processing, and in particular relates to a highly efficient and water-saving cashmere fabric dyeing device and a dyeing method. Background Art

[0002] When cashmere fabrics are processed, they need to be dyed according to color requirements. The most common dyeing method is immersion dyeing, where the fabrics are sent into a dyeing tank through a guide roller for dyeing, and then a press roller is used to squeeze out the remaining dye solution and then dry it.

[0003] Cashmere fabric itself is relatively thick, cashmere fibers have more pores and better water absorption, and cashmere is relatively fragile. It is easy to damage the cashmere by squeezing. Therefore, excessive pressure cannot be applied, resulting in excessive dye residue, which not only wastes the dye, but also increases the drying energy consumption in the subsequent drying process. Summary of the invention

[0004] The purpose of the present invention is to provide a cashmere fabric dyeing device and a dyeing method with high efficiency and water saving in order to solve the above problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A highly efficient and water-saving cashmere fabric dyeing device comprises a dyeing tank and a plurality of fabric guide rollers, wherein the dyeing tank has two sides AB, the A side is provided with a water-spinning assembly, the water-spinning assembly comprises a flywheel located on the inner wall of the A side, a third guide roller parallel to the flywheel axis is provided on the edge of the flywheel, a pair of second guide rollers extend from the inner wall of the B side of the dyeing tank, the two second guide rollers are close to the flywheel center and parallel to the flywheel axis, and are used to guide the fabric from the flywheel center to the third guide roller, and the flywheel is driven by the driving assembly to reciprocate to drive the fabric between the third guide roller and the second guide roller to spin off water.

[0007] As a further optimization scheme of the present invention, a pair of water baffles are also provided on the inner wall of the B side of the dyeing tank to block the water stains swung out. Since the reciprocating rotation of the flywheel creates centrifugal force to dry the fabric, the swung out dye has a tendency to fly upwards. In order to prevent the dye from splashing or even re-staining the fabric, a water baffle is provided in this scheme.

[0008] As a further optimization scheme of the present invention, a pair of first guide rollers are also arranged between the inner walls of the dyeing tank, the first guide roller is used to introduce the fabric into the second guide roller, and a sliding block is arranged at the axial end of the first guide roller, the sliding block is slidably connected to the side wall of the dyeing tank, and a spring is arranged in the sliding direction of the sliding block. Since the third guide roller moves with the edge of the flywheel during the water-throwing process, although the second guide roller is arranged near the center of the flywheel, the fabric will still be subjected to a small amount of pulling force during the water-throwing process. Therefore, the first guide roller is arranged to slide appropriately after the fabric is subjected to force, so as to reduce the pulling force on the fabric.

[0009] As a further optimization scheme of the present invention, a pair of accumulators are provided on the inner wall of the A side of the dyeing tank, and a boss is provided near the edge of the side of the flywheel away from the second guide roller. When the flywheel rotates, the boss compresses the accumulator to store energy so that the flywheel has the potential energy for reverse rotation after deceleration. Since the fabric is on the guide roller transmission line, it can only be dried by rotating the flywheel half a circle. The limited rotation angle results in a short rotation stroke, which requires the flywheel to have a greater acceleration capability. Direct acceleration through the drive assembly requires a larger power for acceleration and deceleration. While acceleration through the accumulator recovers the potential energy after the flywheel rotates to help the flywheel accelerate in the reverse direction.

[0010] As a further optimization scheme of the present invention, the driving assembly is used to provide power to the flywheel to further compress the accumulator when the boss compression accumulator reaches the maximum value, and it includes two clutches. The flywheel is coaxially provided with a gear plate, and the A side wall of the dyeing tank is provided with two output gears respectively meshed with the gear plate and used to connect the clutch. The two clutches are driven by a motor, and the input rotation directions of the two clutches are opposite. The clutch has a clutch paddle, which is driven by a control component and is used to connect the clutch to further compress the accumulator when the boss compression accumulator reaches the maximum value, and release the clutch after compression. In this scheme, , by setting a clutch to connect and disconnect the power, although the potential energy can be accumulated through the accumulator, there is still energy loss. In order to compensate for the loss, the two clutches are used to drive the gear plate to rotate in different directions. When the flywheel compresses the accumulator to the maximum value, the flywheel speed is zero. At this time, the clutch is connected to drive the flywheel to continue to compress the accumulator to compensate for the lost energy. After compression, it is released and the flywheel is pushed by the accumulator to reverse, which compresses another accumulator, and so on. Since the amplitude of the continued compression process is small, the motor only needs to increase the torque through the reducer, and the power demand is small.

[0011] As a further optimization solution of the present invention, the control component is a pair of bevel blocks arranged on the surface of the gear disk. The clutch paddle is hinged on the surface of the clutch, and a one-way rotating rod is arranged at the end of the clutch paddle. The axis of the one-way rotating rod is perpendicular to the axis of the clutch paddle. When the inclined surface of the bevel block contacts the one-way rotating rod, it drives the clutch paddle to rotate and engage the clutch, and when the bevel block returns, it pushes the one-way rotating rod directly through. This solution provides a mechanical control component. By setting two bevel blocks and cooperating with the one-way rotating rod at the end of the clutch paddle, the clutch is engaged after the gear disk rotates in place.

[0012] As a further optimization solution of the present invention, the clutch includes a friction sleeve connected to the motor and a sliding shaft slidably connected to the output gear. A friction plate corresponding to the friction sleeve is arranged on the sliding shaft. The specific structure of the clutch is the prior art. However, different from the prior art, the clutch in this solution is normally open and only closes when the clutch paddle is pressed. And in order to adapt to the pressing direction, the friction sleeve and the friction plate are provided.

[0013] In order to apply the above dyeing device, the present invention also proposes a high-efficiency water-saving dyeing method for cashmere fabrics. Dyeing is carried out using the above dyeing device, including the following steps:

[0014] S1: Inject the dyeing solution into the dyeing tank, and the liquid level of the dyeing solution is lower than the bottom end of the flywheel. The fabric is distributed in the dyeing tank via the fabric guide roller.

[0015] S2: Heat the dyeing solution to 60 - 80 °C, and slowly pull the fabric to move through the traction device, so that the fabric evenly passes through the dyeing solution, and the fabric stays in the dyeing solution for 20 - 30 minutes.

[0016] S3: Drive the flywheel to rotate reciprocally by the driving component, and the rotation angle is 150° - 180°, driving the fabric between the second guide roller and the third guide roller to drain water.

[0017] The beneficial effects of the present invention are as follows:

[0018] The present invention uses the flywheel and the third guide roller to drain water from the fabric during the transmission of the guide roller. The second guide roller is arranged at the center of the flywheel. During the process of the third guide roller draining water, it will not have a great impact on the tension of the fabric, and does not affect the overall transmission of the fabric. Draining water by centrifugal force will not cause great damage to the fabric. Compared with the water squeezing by the pressing roller, the centrifugal water draining method can effectively remove the water stains in the pores, has a better cleaning effect, is more water-saving, and the subsequent drying process is more energy-efficient.

[0028] The following further describes the present application in conjunction with the attached drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0029] Embodiment 1

[0030] As Figures 1-8As shown, a highly efficient and water-saving cashmere fabric dyeing device comprises a dyeing tank 1 and a plurality of fabric guide rollers 11. The dyeing tank 1 has two sides AB. A water-spinning assembly 2 is arranged on the A side. The water-spinning assembly 2 comprises a flywheel 21 located on the inner wall of the A side. A third guide roller 22 axially parallel to the flywheel 21 is arranged on the edge of the flywheel 21. A pair of second guide rollers 14 extend from the inner wall of the B side of the dyeing tank 1. The two second guide rollers 14 are close to the center of the flywheel 21 and axially parallel to the flywheel 21, and are used to guide the fabric from the center of the flywheel 21 to the third guide roller 22. The flywheel 21 is driven to rotate reciprocatingly by the driving assembly 3 to drive the fabric between the third guide roller 22 and the second guide roller 14 to spin off water.

[0031] This solution uses a flywheel 21 and a third guide roller 22 to spin water on the fabric being transmitted by the guide rollers, and the second guide roller 14 is set at the center of the flywheel 21. During the spinning process of the third guide roller 22, the tension of the fabric will not be greatly affected, and the overall transmission of the fabric will not be affected. Spinning water by centrifugal force will not cause great damage to the fabric. Compared with squeezing water by a pressure roller, centrifugal spinning can effectively remove water stains in the pores, has a better cleaning effect, is more water-saving, and the subsequent drying process is more energy-efficient.

[0032] A pair of water baffles 12 are also provided on the inner wall of the B side of the dyeing tank 1 to block the water stains swung out. Since the reciprocating rotation of the flywheel 21 creates centrifugal force to dry the fabric, the swung out dye has a tendency to fly upward. In order to prevent the dye from splashing or even re-staining the fabric, the present solution provides a water baffle 12.

[0033] A pair of first guide rollers 13 are also arranged between the inner side walls of the dyeing tank 1. The first guide roller 13 is used to guide the fabric into the second guide roller 14. A sliding block 1301 is arranged at the axial end of the first guide roller 13. The sliding block 1301 is slidably connected to the side wall of the dyeing tank 1. A spring 1302 is arranged in the sliding direction of the sliding block 1301. Since the third guide roller 22 moves with the edge of the flywheel 21 during the water-throwing process, although the second guide roller 14 is arranged near the center of the flywheel 21, the fabric will still be subjected to a small amount of pulling force during the water-throwing process. Therefore, the first guide roller 13 is arranged to slide appropriately after the fabric is subjected to force to reduce the pulling force on the fabric. Figure 2 and Figure 4 As shown, the first guide roller 13 collapses in the direction of the spring 1302 after being affected by the change in fabric tension.

[0034] On the inner wall of the A side of the dyeing tank 1, a pair of accumulators 24 are provided. On the side surface of the flywheel 21 away from the second guide roller 14 and near the edge, a boss 23 is provided. When the flywheel 21 rotates, the boss 23 compresses the accumulator 24 for energy storage, so that the flywheel 21 has the potential energy for reverse rotation after deceleration. Since the fabric is on the guide roller transmission line, it can only be dried by the flywheel 21 rotating half a circle. The limited rotation angle results in a short rotation stroke, so the flywheel 21 needs to have a large acceleration ability. Directly accelerating through the drive assembly 3 requires a large power for acceleration and deceleration, while accelerating through the accumulator 24 recovers the potential energy after the flywheel 21 rotates to help the flywheel 21 reverse-rotate and accelerate, as Figure 5 shown, a form of the accumulator 24 is given, which includes a sliding seat, a sliding rod, an energy storage spring, and an elastic contact part provided on the dyeing tank 1. When the boss 23 contacts the elastic contact part, the energy storage spring is compressed.

[0035] The drive assembly 3 is used to provide power for the flywheel 21 to further compress the accumulator 24 when the boss 23 compresses the accumulator 24 to the maximum value. It includes two clutches 32. A gear disk 25 is coaxially arranged on the flywheel 21. On the A side wall of the dyeing tank 1, two output gears 33 are provided which are respectively meshed with the gear disk 25 and used to connect the clutches 32. The two clutches 32 are driven by a motor 31, and the input rotation directions of the two clutches 32 are opposite. The clutch 32 has a clutch release lever 35. The clutch release lever 35 is driven by a control component and is used to connect the clutch 32 to further compress the accumulator 24 when the boss 23 compresses the accumulator 24 to the maximum value, and release the clutch 32 after compression.

[0036] In this solution, by setting the clutch 32 for on-off connection of power, although potential energy can be accumulated through the accumulator 24, there is still energy loss. To supplement this loss, the two clutches 32 are respectively used to drive and rotate the gear disk 25 in different directions. When the flywheel 21 compresses the accumulator 24 to the maximum value, the speed of the flywheel 21 is zero. At this time, the clutch 32 is connected to drive the flywheel 21 to continue compressing the accumulator 24 to supplement the lost energy. After compression, it is released. The flywheel 21 is pushed by the accumulator 24 to reverse and instead compress the other accumulator 24, and so on. Since the amplitude of this continuous compression process is small, for the motor 31, only the torque needs to be increased through a speed reducer, and the power requirement is small.

[0037] The control component is a pair of bevel blocks 2501 provided on the surface of the gear disk 25. The clutch release lever 35 is hinged on the surface of the clutch 32. One end of the clutch release lever 35 is provided with a one-way rotating rod 36. The axis of the one-way rotating rod 36 is perpendicular to the axis of the clutch release lever 35. When the inclined surface of the bevel block 2501 contacts the one-way rotating rod 36, it drives the clutch release lever 35 to rotate and connect the clutch 32, while when the bevel block 2501 returns, it pushes away the one-way rotating rod 36 and passes directly through.

[0038] This solution provides a mechanical control component. By setting two bevel blocks 2501 and cooperating with the one-way rotating rod 36 at the end of the clutch lever 35, the clutch 32 is engaged after the gear disc 25 rotates in place. Specifically, as Figures 7-8 shown, the one-way rotating rod 36 can only rotate downward and is held at Figure 8 the highest angle shown by a torsion spring. Also, the shaft of the clutch lever 35 is held in the state where the clutch 32 is disengaged by a torsion spring. As Figure 4 shown, the gear disc 2 rotates clockwise. At this time, the flywheel 21 has already contacted the accumulator 24 for deceleration. When the gear disc 2 continues to rotate, the inclined surface of the bevel block 2501 contacts the one-way rotating rod 36. Since the one-way rotating rod 36 cannot continue to rotate upward, the inclined surface pushes the one-way rotating rod 36 and the clutch lever 35 to rotate along the shaft of the clutch lever 35, that is, the clutch lever 35 connects the clutch 32. The output gear 33 corresponding to this clutch 32 drives the gear disc 25 to continue rotating clockwise until the bevel block 2501 leaves the one-way rotating rod 36, then the clutch lever 35 disengages. The gear disc 25 that loses power access follows the flywheel 21 and is pushed by the accumulator 24 to accelerate in the reverse direction. When the gear disc 25 rotates counterclockwise, the bevel block 2501 passes by the one-way rotating rod 36 again and directly pushes the one-way rotating rod 36 through. And so on. There are two bevel blocks 2501, and their inclined surfaces are respectively used to face different one-way rotating rods 36. At the start, the gear disc 25 is in a static state and both clutches 32 are in the disengaged state. One of the clutch levers 35 can be pulled open manually, and when the bevel block 2501 rotates in place, it can be released to let the device run automatically.

[0039] The clutch 32 includes a friction sleeve 3201 connected to the motor 31 and a sliding shaft 3203 slidably connected to the output gear 33. The sliding shaft 3203 is provided with a friction plate 3202 corresponding to the friction sleeve 3201. The specific structure of the clutch 32 is prior art, but different from the prior art, the clutch 32 in this solution is normally open and only closes when the clutch lever 35 is pressed. And in order to adapt to the pressing direction, the friction sleeve 3201 and the friction plate 3202 are provided.

[0040] In addition, the input directions of the two clutches 32 are opposite, so the two clutches 32 can be redirected through bevel gears and the transmission member 34 and driven by the same motor 31. The motor 31, the clutch 32, and the transmission member 34 are all fixed by the bracket platform 4.

[0041] To apply the above dyeing device, the present invention also proposes an efficient water-saving method for dyeing cashmere fabrics. Dyeing is carried out using the above dyeing device, including the following steps:

[0042] S1: Inject the dye liquor into the dyeing bath 1, and the liquid level of the dye liquor is lower than the bottom end of the flywheel 21. Distribute the fabric in the dyeing bath 1 via the fabric guide roller 11.

[0043] S2: Heat the dye liquor to 60 °C, and slowly pull the fabric to move through the traction device, so that the fabric evenly passes through the dye liquor, and the residence time of the fabric in the dye liquor is 30 min.

[0044] S3: Drive the flywheel 21 to rotate reciprocally by the driving component 3, the rotation angle is 150 °, and drive the fabric between the second guide roller 14 and the third guide roller 22 to drain water.

[0045] Embodiment 2

[0046] Different from Embodiment 1, in this embodiment, the dye liquor is heated to 80 °C, the residence time of the fabric in the dye liquor is 20 min, and the rotation angle is 180 °.

[0047] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
