Description

Technical Field

[0001] This invention belongs to the field of fabric washing, and particularly relates to a fabric washing anti-wrinkle process and anti-wrinkle expansion device. Background Technology

[0002] Modern fabric printing and dyeing is a continuous process with machine speeds reaching hundreds of meters per minute. The post-printing and dyeing process includes a fabric washing step, in which the fabric is washed with high-temperature water. Due to the fast movement of the fabric, in order to allow the fabric to have a longer washing time and a more thorough washing, the fabric is repeatedly bent and passed through the washing equipment by multiple steering rollers.

[0003] In actual production, it was found that many fabrics are sensitive to temperature due to their material properties. For example, silk, wool, and Tencel fabrics are prone to localized shrinkage after washing, resulting in wrinkles after drying. Wrinkles do not appear along the length of the fabric due to traction; they mainly appear along the width. Since the fabric is packaged in rolls after drying, wrinkles are difficult to detect and can easily end up in downstream factories. Although downstream factories can remove wrinkles through ironing, this negatively impacts the dyeing and printing factories and increases labor costs. Summary of the Invention

[0004] The purpose of this invention is to provide a fabric washing and wrinkle-resistant process and a wrinkle-resistant widening device. This invention has the advantage of eliminating wrinkles during fabric washing.

[0005] The technical solution of the present invention is a fabric washing and anti-wrinkle process. In a continuous fabric printing and dyeing production line, when the fabric is washed, a tensile force is applied to both sides of the fabric in the width direction to make the wrinkles on the fabric disappear.

[0006] In the aforementioned fabric washing and wrinkle-resistant process, by applying tension to both sides of the fabric in the width direction by the turning roller, the fabric expands when turning, thus eliminating wrinkles.

[0007] The anti-wrinkle and widening device for realizing the aforementioned fabric washing and anti-wrinkle process includes a frame and multiple steering rollers. Each end of the steering roller is provided with a push block fixed to the frame. The two push blocks are distributed in a mirror image and are coaxial with the steering roller. The frame is provided with a motor whose output end is connected to the steering roller. The outer circumferential surface of the steering roller is provided with multiple sets of circumferentially evenly distributed sliding plates. The outer side wall of the sliding plate is an arc surface. The outer side walls of multiple sets of sliding plates are located on the same cylindrical surface. Each set of sliding plates includes two sliding plates. A spring is provided between the inner ends of the two sliding plates. The outer ends of the two sliding plates are respectively connected to the inclined surface of the corresponding push block. The sliding plates slide on the inner end surface of the push block.

[0008] In the aforementioned anti-wrinkle and expansion device, the outer circumferential surface of the steering roller is provided with a plurality of circumferentially evenly distributed sliding grooves, the inner sidewall of the slide plate is provided with a sliding strip that cooperates with the sliding grooves, and the spring is located in the sliding groove, the diameter of the spring being smaller than the groove opening width.

[0009] In the aforementioned anti-wrinkle expansion device, both the outer end face of the slide plate and the outer end face of the slide bar are provided with ball cavities, and ball bearings are provided inside the ball cavities.

[0010] In the aforementioned anti-wrinkle expansion device, two ball cavities are provided on the outer end face of the slide plate, and the two ball cavities are respectively located on both sides of the slide plate in the width direction.

[0011] In the aforementioned anti-wrinkle expansion device, the inner end face of the push block is provided with an outer raceway and an inner raceway with a semi-circular cross section. The balls located on both sides of the slide plate in the width direction are located in the outer raceway, and the balls located on the slide bar are located in the inner raceway.

[0012] In the aforementioned anti-wrinkle and expansion device, the steering roller is a tubular structure, with a first plug shaft and a second plug shaft respectively provided on the inner sides of both ends of the steering roller. The first plug shaft is rotatably connected to the steering roller and fixed to a push block at one end. The second plug shaft is key-connected to the steering roller and passes through the push block at the other end before connecting to the output end of the motor. The second plug shaft is rotatably connected to the frame.

[0013] In the aforementioned anti-wrinkle expansion device, under the action of the spring, the outer ends of each set of sliding plates are in contact with the corresponding push block, and different distances are formed between the inner ends of each set of sliding plates. The set of sliding plates with the smallest distance is located at the starting point of the fabric's turn.

[0014] In the aforementioned anti-wrinkle spreading device, the outer side wall of the slide plate is provided with multiple inclined grooves, the depth of which is 0.1-0.2mm. The rotation direction of the rotating roller is the same as the bending and moving direction of the fabric. The circumferential moving linear velocity of the outer side wall of the slide plate is higher than the moving speed of the fabric. In the rotation direction of the slide plate, the front end of the inclined groove is close to the inner end of the slide plate.

[0015] Compared with existing technologies, this invention improves the structure of the guide roller on the original production line by installing multiple sets of sliding plates on the guide roller, with springs between each set of sliding plates. Push blocks are installed at both ends of the guide roller, and the push blocks connect with the inclined surfaces of the sliding plates. When the guide roller rotates, the sliding plates move on the push blocks, using the push blocks to cause the sliding plates to reciprocate axially. The area where the sliding plates move outwards is positioned within the bending and wrapping corner area of ​​the fabric. Utilizing the friction between the sliding plates and the fabric, a pulling force is applied to both sides of the fabric's width, causing the fabric to expand during turning and eliminating wrinkles. Therefore, this invention has the advantage of eliminating fabric washing wrinkles.

[0016] By setting a groove on the guide roller and placing the spring in the groove, the diameter of the spring is smaller than the width of the groove opening, which prevents the spring from bending and extending out of the guide roller during the extension and contraction process, and prevents the spring from contacting the fabric and causing the fabric to wrinkle.

[0017] By setting ball cavities on both sides of the slide plate end face and on the end face of the slide bar, and setting ball bearings in the ball cavities, and setting a raceway on the push block, a rolling friction connection is established between the slide plate and the push block, reducing wear between the slide plate and the push block, improving the service life of the device, and avoiding fabric contamination caused by wear debris falling onto the fabric.

[0018] By setting a groove with a depth of less than 0.2mm on the skateboard, the fabric will be embedded into the groove due to the tension on the fabric. The low depth of the groove ensures that the fabric embeds into the groove with a low amplitude, so that it will not deform or wrinkle, but it can greatly increase the friction between the fabric and the skateboard, so that the fabric can obtain more tension and the wrinkle elimination effect is better.

[0019] Because the front end of the sloping groove is close to the inner end of the skateboard in the direction of the skateboard's rotation, each sloping groove can provide outward pulling force to the fabric. The combined effect of multiple pulling forces makes the wrinkle elimination effect even better. Attached Figure Description

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0029] Example: A wrinkle-resistant and width-expanding device is installed on a continuous fabric dyeing production line, corresponding to the high-temperature washing station, such as... Figure 1 As shown, the machine includes a frame 1 and multiple tubular guide rollers 2. The fabric passes over the multiple guide rollers 2 to increase the length of the fabric 5 through the washing station and increase the washing time of the fabric 15.

[0030] like Figure 4 As shown, push blocks 3 fixed to the frame 1 are provided on the outer sides of both ends of the steering roller 2. The two push blocks 3 are mirror images of each other and are coaxial with the steering roller 2. A motor 4 is provided on the frame 1. A first plug shaft 13 and a second plug shaft 14 are provided on the inner sides of both ends of the steering roller 2, respectively. The first plug shaft 13 is rotatably connected to the steering roller 2 and is fixed to the push block 3 on the left end. The second plug shaft 14 is keyed to the steering roller 2 and passes through the push block 3 on the right end before connecting to the output end of the motor 4. The frame 1 and the push block 3 on the right end are both rotatably connected to the second plug shaft 14.

[0031] Multiple sets of circumferentially evenly distributed sliding plates 5 are provided on the outer circumferential surface of the steering roller 2. The outer side wall of the sliding plate 5 is an arc surface. The outer side walls of the multiple sets of sliding plates 5 are located on the same cylindrical surface. Each set of sliding plates 5 includes two sliding plates 5. A spring 6 is provided between the inner ends of the two sliding plates 5. The outer ends of the two sliding plates 5 are respectively connected to the inclined surface of the corresponding push block 3. The inclined surface maintains an angle of about 10° with the axis of the steering roller 2. The sliding plate 5 slides on the inner end surface of the push block 3.

[0032] The outer circumferential surface of the steering roller 2 is provided with a plurality of circumferentially evenly distributed sliding grooves 7, the sliding grooves 7 being dovetail grooves. The inner side wall of the slide plate 5 is provided with a sliding strip 8 that cooperates with the sliding grooves 7. The outer end of the sliding strip 8 extends to be flush with the outer end face of the slide plate 5. The spring 6 is located in the sliding groove 7. The diameter of the spring 6 should be greater than the width of the groove opening of the sliding groove 7. The sliding groove 7 is used to guide the spring 6, preventing the spring 6 from bending and protruding from the surface of the steering roller 2, preventing it from touching the fabric 15, and preventing the fabric 15 from wrinkling.

[0033] Both the outer end face of the slide plate 5 and the outer end face of the slide bar 8 are provided with ball cavities 10, and ball balls 9 are provided inside the ball cavities 10. Two ball cavities 10 are provided on the outer end face of the slide plate 5, and the two ball cavities 10 are respectively located on both sides of the width direction of the slide plate 5.

[0034] The inner end face of the push block 3 is provided with an outer raceway 11 and an inner raceway 12 with a semi-circular cross section. The balls 9 located on both sides of the slide plate 5 in the width direction are located in the outer raceway 11, and the balls 9 located on the slide bar 8 are located in the inner raceway 12.

[0035] Under the force of spring 6, the outer ends of each set of slides 5 are in contact with the corresponding push block 3, and the inner ends of each set of slides 5 are separated by different distances. The slide group with the smallest distance is located at the turning point of the fabric 15, and the distance between the two slides 5 of the smallest group is about 0.5mm.

[0036] The outer side wall of the slide plate 5 is provided with multiple inclined grooves 16. The two ends of the inclined grooves 16 are respectively located on the two wide side walls of the slide plate 5. The depth of the inclined grooves 16 is 0.1-0.2mm and the width is 2-4mm. The edges and corners of the inclined grooves 16 are sanded to avoid leaving burrs. The rotation direction of the rotating roller is the same as the bending and moving direction of the fabric 15. The circumferential moving linear velocity of the outer side wall of the slide plate 5 is higher than the moving speed of the fabric 15. In the rotation direction of the slide plate 5, the front end of the inclined groove 16 is close to the inner end of the slide plate 5.

[0037] Working principle: such as Figure 4 As shown, the motor 4 drives the steering roller 2 to rotate through the second piston shaft 14, while the push block 3 and the frame 1 are fixed and remain stationary.

[0038] For the two slide plates 5 in the same group, under the action of the spring 6, there is always an outward force, but they are limited by the push blocks 3 on both sides, keeping their outer end faces in contact with the push blocks 3. The steering roller 2 drives the slide plate 5 to rotate. Since the inner end face of the push block 3 is inclined, the slide plate 5 will move axially during one rotation, and the distance between the two slide plates 5 changes periodically.

[0039] When installing push block 3 onto frame 1, it should be noted that when the fabric is bent, the starting point of the bend corresponds to the minimum distance between the two push blocks 3, that is, the starting point of the fabric 15 bending and turning is on the slide plate group with the minimum distance.

[0040] When the fabric is bent by the turning roller 2, there is a corner. When any set of slide plates 5 passes through the corner area, both slide plates 5 move outward. Using the friction between the slide plates 5 and the fabric, a pulling force is applied to both sides of the width of the fabric 15, so that the fabric 15 expands when turning and eliminates wrinkles.

They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations.
