Technical Field

[0001] The invention relates to the technical field of patchwork cloth winding, in particular to an anti-wrinkle device for a patchwork cloth processing winding device. Background Art

[0002] In the patchwork manufacturing process of the textile industry, the winding process is a key step in accurately combining and winding multi-layer or multi-color fabrics into a cylinder or disc shape. This process is directly related to the smoothness of subsequent cutting and sewing work, as well as the quality of the final product.

[0003] Since the patchwork cloth is prone to deviation during the winding process, the cloth is not evenly wound, and the patchwork area is prone to excessive stretching or bending, resulting in folding together with other parts. This uneven force and arrangement will form wrinkles on the cloth. In existing correction equipment, the deviation of the patchwork cloth is mainly prevented by a tension control mechanism, and it is unable to automatically adjust and protect according to the deviation state of the patchwork cloth, which makes it easy for the patchwork cloth to be excessively deformed or torn at the patchwork joints during the tension calibration process.

[0004] Therefore, according to the above-mentioned requirements, a wrinkle-proof device for a patchwork processing winding device is designed. Summary of the invention

[0009] As a further preferred solution, the fixing bracket is located at the front side of the fixing frame.

[0010] As a further preferred solution, two sides of the fixing frame are inclined outwards to guide the third roller to straighten the wrinkles of the patchwork cloth.

[0011] As a further preferred solution, a knob is fixedly connected to one side of the third screw rod for manually turning the third screw rod.

[0012] As a further preferred solution, the adjustment mechanism also includes a rack frame, which is fixedly connected to the side wall of the first sliding frame, and a second gear is fixedly connected to the side of the second screw rod adjacent to the rack frame, and the second gear is meshed with the rack frame.

[0016] The present invention has the following advantages: the present invention realizes automatic real-time correction of the moving distance of the first sliding frame by moving it in the opposite direction to the offset direction of the patchwork, thereby preventing the patchwork from deviating and causing wrinkles in subsequent winding.

[0017] Through the cooperation of the fixing frame and the third roller, the patchwork cloth can be assisted in being straightened before entering the equipment, so as to prevent the patchwork cloth from being wrinkled when being wound and affecting the winding quality.

[0018] Through the cooperation of the second gear and the rack frame, when the patchwork deviates, the second gear and the second screw are driven to rotate clockwise, thereby increasing the clamping force on the patchwork and preventing the patchwork from being separated from the first roller and the second roller, thereby affecting the subsequent patchwork winding work and causing patchwork wrinkles. At the same time, when the patchwork deviates too much, the clamping of the patchwork will be automatically released to prevent the patchwork from being damaged, thereby affecting the product quality.

[0033] Embodiment 1: A wrinkle-proof device for a patchwork winding device, such as Figure 1-Figure 4As shown, it includes a fixed frame 101, and a symmetrically arranged first motor 102 is fixedly installed on the left and right sides of the fixed frame 101, a connecting frame 1021 is fixedly connected to the top of the fixed frame 101, and a first screw 103 is fixedly sleeved on the output shaft end of the symmetrically arranged first motor 102, and a symmetrically arranged first sliding frame 104 is slidably connected to the left and right sides of the fixed frame 101, and the symmetrically arranged first sliding frame 104 is threadedly connected to the first screw 103, and the symmetrically arranged first sliding frame 104 is slidably connected to the side away from the first motor 102 with a second sliding frame 105, and a trapezoidal protrusion is provided on the front side of the lower part of the second sliding frame 105 for applying pressure to the pressure sensor 106, so as to control the first motor 102 to drive the first sliding frame 104 to move and compensate for its offset position. The pressure sensor 106 is fixedly connected to the front of the side wall of the outer side of the symmetrically arranged first sliding frame 104 close to the second sliding frame 105, and the pressure sensor 106 is electrically connected to the first motor 102 through the control module. A telescopic spring 107 is fixedly connected between the inner wall of the symmetrically arranged first sliding frame 104 and the side wall of the second sliding frame 105. The side of the second sliding frame 105 away from the first screw 103 is rotatably connected to the first roller 108. The bottom of the second sliding frame 105 is slidably connected to the first sliding block 109, and the inner side of the first sliding block 109 is rotatably connected to the second roller 110. The second sliding frame 105 is rotatably connected to the second screw 111, and the second screw 111 is threadedly connected to the first sliding block 109. An adjustment mechanism is provided on one side of the first sliding frame 104.

[0034] Working principle: First, the entire anti-wrinkle device is fixed to the front side of the winding shaft near the winder through the connecting frame 1021, and then the cloth is passed through the first roller 108 and the second roller 110, and the second screw 111 is turned clockwise to drive the first sliding block 109 and the second roller 110 to rise, and the patchwork is clamped. After passing through the first roller 108 and the second roller 110, the patchwork is wound onto the winding shaft of the winder to complete the patchwork clamping work.

[0035] After that, the winding machine is started to wind the patchwork cloth. The first roller 108 and the second roller 110 on both sides of the fixed frame 101 are clamped to limit the deviation of the patchwork cloth. In order to avoid the aging of the equipment winding shaft or improper setting of equipment parameters during the patchwork cloth winding process, which leads to unstable tension control and causes the cloth to deviate to one side during winding, the deviation to the right side is illustrated below:

[0036] When the patchwork is affected by the winding shaft and deviates to the right side during the winding process, the patchwork will pull the first roller 108, the second roller 110, the second sliding frame 105, the first sliding block 109 and the second screw 111 on the left side of the fixed frame 101 to move inward to the right, resulting in position deviation. The telescopic spring 107 is deformed and compressed under the force, and the second sliding frame 105 and other components on the right side of the fixed frame 101 are pushed to the right by the patchwork. In the process of the second sliding frame 105 on the left side moving to the right, the trapezoidal protrusion squeezes the pressure sensor 106, and the pressure sensor 106 sends an electrical signal. The control module receives the electrical signal to drive the first motor 102 to operate. The first motor 102 drives the first screw 103 to rotate counterclockwise, thereby pushing the first sliding frame 104 on the left side of the fixed frame 101 to move to the left, and then pushing the second sliding frame 105 and the corresponding components connected to the second sliding frame 105 to move to the left, which is caused by the second sliding frame 105 being affected by the patchwork and deviating to the right. The distance is compensated, and finally the offset position of the patchwork is corrected, and the patchwork drives the second sliding frame 105 and other components on the right side to reset to the left side. When the pressure sensor 106 is squeezed by the trapezoidal protrusion, the greater the pressure, the greater the number of turns of the first motor 102 until the offset position of the second sliding frame 105 is compensated back to the initial position. As the patchwork gradually returns to its normal position, the pulling force of the patchwork on the first roller 108 is gradually reduced, and the telescopic spring 107 is gradually deformed and reset, thereby pulling the second sliding frame 105, the first roller 108, the first sliding block 109, the second roller 110 and the second screw 111 to move to the left, so that the trapezoidal protrusion of the second sliding frame 105 moves to the left, reducing the pressure on the pressure sensor 106, and the first motor 102 drives the first screw 103 to rotate clockwise, thereby driving the first sliding frame 104 to move to the right and reset, thereby compensating for the distance that the telescopic spring 107 pushes the second sliding frame 105 to the left excessively deviated during the resetting process.

[0037] When the patchwork deviates to the left, the patchwork is corrected by repeating the above working principle and moving in the opposite direction. In summary, when the patchwork deviates, the first sliding frame 104 moves in the opposite direction of the patchwork deviation, thereby automatically correcting the moving distance in real time to prevent the patchwork from deviating and causing wrinkles in the subsequent winding.

[0038] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, it also includes a fixing frame 201, which is fixedly connected to the side wall of one side of the fixing frame 101, and the fixing frame 201 is located on the front side of the fixing frame 101. Both sides of the fixing frame 201 are inclined outward, which is used to guide the roller to straighten the folds of the patchwork. The fixing frame 201 is fixedly installed with a symmetrically arranged second motor 202 on the left and right sides, and the fixing frame 201 is slidably connected to a second sliding block 203 symmetrically arranged along the fixing frame 201. The fixing frame 201 is rotatably connected to a third roller 204 symmetrically arranged along the left and right sides of the fixing frame 201, and the second sliding block 203 is also rotatably connected to the third roller 204. The third roller 204 on the fixed frame 201 is fixedly connected to the output shaft of the adjacent second motor 202. The third roller 204 on the fixed frame 201 is located above the third roller 204 on the adjacent second sliding block 203. The fixed frame 201 is rotatably connected to a third screw 205 symmetrically arranged along the fixed frame 201. A knob is fixedly connected to the top of the third screw 205 for manually turning the third screw 205 to adjust it. The symmetrically arranged third screw 205 is threadedly connected to the second sliding block 203. The third roller 204 is fixedly connected to a first gear 206, and adjacent first gears 206 are meshed with each other.

[0039] In order to assist in straightening the patchwork before it enters the winding device to prevent it from wrinkling, the specific operation is as follows: first, before the patchwork passes through the first roller 108 and the second roller 110, it first passes through the third roller 204, and then the third screw 205 is screwed, and the third screw 205 drives the second sliding block 203, the third roller 204 and the first gear 206 to move upward to clamp the patchwork, so that the first gear 206 between the third roller 204 is meshed with each other, and then the second motor 202 is started to rotate, thereby driving The first gears 206 rotate relative to each other, thereby driving the third roller 204 to rotate relative to each other, and transporting the patchwork to the rear side. During the transportation process, a certain angle is formed toward the outside by the two sides of the fixed frame 201, so that the third roller 204 provides a lateral pulling force while providing forward power to straighten the wrinkled patchwork. In summary, through the cooperation of the fixed frame 201 and the third roller 204, the patchwork is assisted in straightening before entering the equipment, so as to prevent the patchwork from wrinkling when winding and affecting the winding quality.

[0040] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the adjustment mechanism also includes a rack frame 301, which is fixedly connected to the side wall of the upper portion of the first sliding frame 104, and racks are staggeredly arranged on the front and rear sides of the rack frame 301 for adjusting the tightness of the first roller 108 and the second roller 110, and a second gear 302 is fixedly connected to the side of the second screw 111 adjacent to the rack frame 301, and the second gear 302 is meshed with the rack frame 301.

[0041] When the patchwork is deviated, the patchwork is prevented from being separated from the first roller 108 and the second roller 110, which affects the subsequent winding quality and causes wrinkles in the patchwork. At the same time, the patchwork is prevented from being excessively deviated due to the large force of the winding shaft. Since the second sliding frame 105 pulls in the opposite direction, the mutual pulling force between the winding shaft and the first sliding frame 104 causes the patchwork to be torn, deformed or torn. The specific operation is as follows:

[0042] When the patchwork drives the second sliding frame 105 to deviate to the right, the second sliding frame 105, the first roller 108, the first sliding block 109, the second roller 110, the second screw 111 and the second gear 302 on the left side are driven to move to the right. The second gear 302 contacts the first section of the rack on the rear side of the rack frame 301 during the movement. Through the meshing of the second gear 302 and the rack, the second screw 111 is driven to rotate clockwise, thereby driving the first sliding block 109 and the second roller 110 to move upward, thereby increasing the clamping force on the patchwork to prevent it from being separated from between the first roller 108 and the second roller 110.

[0043] When the patchwork is subjected to excessive pulling force and deviates too far to the right, the second sliding frame 105 will move excessively to the right, and the first sliding frame 104 will move excessively to the left to compensate. At this time, in order to prevent the patchwork from being deformed or torn, when the patchwork drives the first sliding frame 104 to move to the right, it passes through the second rack on the front side of the rack frame 301, thereby driving the second gear 302 to drive the second screw 111 to rotate counterclockwise, thereby causing the first sliding block 109 and the second roller 110 to move downward, loosening the patchwork and protecting it. In summary, through the cooperation between the second gear 302 and the rack frame 301, when the patchwork deviates, the second gear 302 and the second screw 111 are driven to rotate clockwise, thereby increasing the clamping force on the patchwork, preventing the patchwork from being separated from the first roller 108 and the second roller 110, affecting the subsequent patchwork winding work and causing patchwork wrinkles. At the same time, when the patchwork deviates too much, it will automatically release the clamping of the patchwork to prevent the patchwork from being damaged, thereby affecting the product quality.

[0044] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 2 and Fig. 9 As shown, it also includes a first fixed block 401, which is fixedly connected to the lower rear part of the first sliding block 109, and a second fixed block 402 is fixedly connected to the lower rear part of the second sliding frame 105, and a fourth roller 403 is rotatably connected between the second fixed block 402 and the first fixed block 401.

[0045] In order to ensure that the patchwork can maintain a flat state better after passing through the first roller 108 and the second roller 110, the specific operation is as follows:

[0046] When the first sliding block 109 drives the second roller 110 to move upward to clamp the patchwork, the first sliding block 109 drives the first fixed block 401 and the fourth roller 403 to move upward, so that the fourth rollers 403 on the upper and lower sides clamp the patchwork, thereby increasing the time and distance for flattening the patchwork. In summary, the cooperation between the first fixed block 401 and the fourth roller 403 improves the stability of the patchwork when it is wound.

[0047] Embodiment 3: Based on embodiment 2, Figure 1 , Figure 2 and Fig.10 As shown, a contact switch 501 is also included. The contact switch 501 is fixedly connected to the upper part of the side wall of the first sliding frame 104. An alarm 502 is fixedly connected to the middle of the top of the connecting frame 1021. The alarm 502 is electrically connected to the contact switch 501 through the control module.

[0048] In order to avoid the situation where the operator cannot be notified in time when the patchwork deviates excessively, the specific operation is as follows: when the patchwork deviates excessively, the second sliding frame 105 on one side of the fixed frame 101 is pulled inward, and since the first sliding frame 104 moves outward, the deviated position of the second sliding frame 105 is compensated, and the first sliding frame 104 continuously moves closer to the second sliding frame 105 during the process of moving outward, so that the second sliding frame 105 contacts and squeezes the contact switch 501 on the side wall of the first sliding frame 104, and the contact switch 501 is compressed by force. When it shrinks to a certain extent, the contact switch 501 sends an electrical signal, and the control module receives the signal and triggers the alarm 502 to sound an alarm, reminding the operator to correct its winding equipment. In summary, through the cooperation between the contact switch 501 and the alarm 502, the operator is reminded in time, ensuring that the problem can be solved in time when it occurs.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
