Description

Technical Field

[0001] The present invention relates to the technical field of fabric winding, and particularly relates to a winding device for textile with an anti-loosening function. Background Art

[0002] In the production of home textile products, for the convenience of storage and subsequent sales, in the last step of the production and processing of textile fabrics, the fabrics are wound and stored through a winding device. The existing winding device includes a frame. On the frame, a telescopic drum is connected through a main shaft. A material roller for winding the fabric is sleeved on the telescopic drum. Then, the telescopic drum expands to fix the material roller. Generally, a swing arm is installed on the side of the frame to tension the fabric. The swing arm generally includes two rotating rods rotatably connected to the side of the frame, and a pressure roller is installed between the two rotating rods. During use, the fabric passes under the pressure roller and is wound around the material roller. The pressure roller deflects downward under its own gravity, so that the fabric is pressed downward to make the fabric taut. Then, when the material roller rotates, the fabric can be wound.

[0003] The magnitude of the pressure of this structure cannot be adjusted, and large fluctuations will occur during the winding process. Different fabrics, such as cotton, chemical fiber, silk, etc., have different thicknesses, elasticities, and frictions. Fabrics with large elasticity may require greater pressure to compensate for elastic deformation, while thinner fabrics may require smaller pressure to avoid excessive compression. For brittle fabrics such as carbon fiber prepreg, too large an initial pressure angle will cause fiber breakage. Therefore, the initial pressure needs to be adjusted when dealing with fabrics of different materials. And as the fabric is continuously wound, the diameter will gradually increase. At this time, how to maintain an appropriate pressing force is the key. Excessive fluctuations in the pressing force may cause the fabric to be too tight or too loose, affecting the winding quality. Summary of the Invention

[0004] A winding device for textile with an anti-loosening function proposed by the present invention solves the above problems.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A winding device for textile with an anti-loosening function includes a frame. Above the rear half of the frame, a main shaft is rotatably installed through a bearing seat. The main shaft is connected to the output end of an external driving device to make the main shaft rotate. An electromagnetic brake is also installed on the output end of the driving device, so that the main shaft will not deflect when the driving device stops. A telescopic drum is fixed on the main shaft. A material roller is installed on the telescopic drum. A speed reducer is installed on the frame. The input end of the speed reducer is connected to the main shaft through a belt pulley and a toothed belt; On the right side of the front half of the frame, a side frame is fixedly installed. A pressure compensation mechanism is installed on the left side of the side frame. The output end of the speed reducer is connected to the pressure compensation mechanism. Two sets of adjusting members symmetrically distributed front and back are installed on the pressure compensation mechanism. Two sets of swing arms are symmetrically installed front and back on the right side of the side frame. The adjusting members are slidably connected to the swing arms. A pressing structure is rotatably installed between the two sets of swing arms.

[0006] Preferably, the pressure compensation mechanism includes two thickened plates symmetrically fixed at the front and rear ends on the left side of the side frame. A compensation member is slidably installed up and down on the thickened plate. Two reset members are installed on the compensation member away from the speed reducer. A driving member is installed on the frame. The driving member is connected to the compensation member.

[0007] Preferably, the driving member includes an output shaft rotatably installed on the frame through a bearing seat. The rear end of the output shaft is connected to the output end of the speed reducer through a coupling. Two sets of gears are installed on the output shaft; The compensation member includes two sets of lifting plates symmetrically distributed. A lifting tooth is arranged on the side of the lifting plate close to the gear. The lifting teeth on the two sets of lifting plates are respectively engaged with the two gears; The speed reducer selects a suitable meshing three-stage reduction gear set according to actual needs. The reduction ratio of this speed reducer is set to 1 / n. Among them, the transmission ratio between the main shaft and the input end of the speed reducer is 1. In this way, the transmission ratio between the speed reducer and the main shaft is n. Thus, for every n rotations of the material roller, that is, after the fabric is wound n times, the output shaft rotates one circle, and the lifting plate rises a certain height accordingly.

[0008] Preferably, two sets of symmetrically distributed rectangular grooves are opened at the upper and lower ends on the left side of the thickened plate. The cross section of the rectangular groove is in a convex shape structure. Specifically, a groove with a convex shape structure is formed by penetrating the thickened plate left and right. Then, the thickened plate is fixed to the left side of the side frame by screws, and a long strip is embedded in the groove. The long strip is fixed to the side frame by screws to form a rectangular groove; Two sets of guide wheels are symmetrically installed up and down and rotatably on the side of the lifting plate close to the side frame. The two guide wheels are respectively placed in the corresponding rectangular grooves in a rolling manner. A pin is arranged on the guide wheel. The pin is fixed to the lifting plate by screws. The cross sections of the pin and the guide wheel are in a convex shape structure.

[0009] Preferably, a pressing plate is welded to the left side of the thickened plate on the front side. A lifting strip hole is formed through the pressing plate from front to back. The reset member includes a fixed straight plate screwed to the front lifting plate. A straight rod is screwed to the fixed straight plate. The front end of the straight rod passes through the lifting strip hole and is located on the front side of the pressing plate. A dial is fixed to the front end of the straight rod. A circular ring is slidably sleeved on the straight rod. The circular ring is located on the rear side of the pressing plate. A compression spring is sleeved on the straight rod. The two ends of the compression spring are respectively abutted against the fixed straight plate and the circular ring. The compression spring makes the fixed straight plate always tend to move backward, and thus makes the lifting plate tend to move backward; When the lifting plate is at the lowest position, the guide wheel is placed at the rearmost side below the loop groove. At this time, the gear meshes with the lifting teeth; When the lifting plate is at the highest position, the material roller needs to be replaced when the fabric is wound to the maximum extent. At this time, the bottom end of the outer ring of the guide wheel is tangent to the top surface of the long strip.

[0010] Preferably, the adjusting member includes an adjusting plate and a fixing plate. The fixing plate is fixed to the lifting plate. The adjusting plate is slidably connected to the fixing plate; A linear sliding groove is formed through the fixing plate from front to back. A linear sliding block is arranged on the side of the adjusting plate facing the fixing plate. The linear sliding block is slidably inserted into the linear sliding groove. A locking bolt is fixed to the linear sliding block. The locking bolt passes through the linear sliding groove and is located outside the fixing plate. A locking nut is connected to the locking bolt. Loosening the locking nut can make the adjusting plate linearly move left and right along the linear sliding groove on the fixing plate. After moving to the required position, tightening the locking nut can fix the adjusting plate.

[0011] Preferably, the swing arm includes two mounting shaft seats symmetrically fixed to the right surface of the side frame from front to back. A lever is rotatably mounted between the two mounting shaft seats through a rotating shaft. An adjusting sliding groove is formed through the lever from front to back. An adjusting sliding rod is arranged at the end of the adjusting plate away from the linear sliding block. The adjusting sliding rod is slidably inserted into the adjusting sliding groove; When the adjusting sliding rod moves to the right under the action of the adjusting plate, the adjusting sliding rod can push the lever to deflect upward with the rotating shaft as the axis, thereby increasing the initial pressure angle. On the contrary, it deflects downward, and can finely calibrate the initial angle of the swing arm to adapt to different fabric characteristics.

[0012] Preferably, the pressing structure includes two side arms. Two pressure rollers are rotatably mounted between the two side arms. An installation pin is fixed above the inner side of the side arm facing inward. The two side arms are respectively rotatably connected to the two levers through the installation pins. A torsion spring is sleeved on the installation pin. One end of the torsion spring is fixed to the side arm, and the other end of the torsion spring is fixed to the lever. The torsion spring makes the two side arms always tend to move downward, so that the fabric between the two pressure rollers tends to move downward, making the fabric taut.

[0013] Preferably, a pressure sensor is installed on the front side of the boom. The front side mounting pin is designed with an extended length and is located in front of the front side arm. A detection member is installed at the front end of the mounting pin. The part of the detection member close to the pressure sensor is designed with an arc-shaped structure to form a detection arc surface. The radian of the detection arc surface gradually increases from bottom to top; That is to say, the detection arc surface is regarded as being composed of countless points. The distance between the lowest point and the axis of the mounting pin is the smallest, and the distance between the highest point and the axis of the mounting pin is the largest. In this way, as more and more fabric is wound on the material roller, without changing the deflection angle of the swing arm, the pressure value between the fabric and the pressure roller becomes larger and larger. The side arm will be lifted, the detection member will deflect accordingly, and the contact position between the detection arc surface and the pressure sensor changes, thereby being able to detect the pressure value.

[0014] Advantages of the present invention: 1. By providing a pressure compensation mechanism on the winding device, this mechanism is connected to the main shaft of the winding device through a speed reducer, and the transmission ratio among the three is distributed as required. After the winding device winds a certain thickness of fabric, the pressure compensation mechanism can make the pressing structure deflect upward by a certain angle for pressure compensation, so that the fabric tension is maintained within the optimal range. In this way, during the subsequent winding process, the tension can always be ensured to be constant, the pressure fluctuation of the pressure roller is reduced, the winding tightness and uniformity of the fabric are improved, and the fabric fibers will not be strained due to excessive tension; 2. An adjusting member is provided on the pressure compensation mechanism. The adjusting member is movably connected to the swing arm. The adjusting member can push the boom to deflect upward or downward with the axis of the rotating shaft, and can finely calibrate the initial angle of the swing arm to a certain extent, thereby increasing or decreasing the initial pressure angle to adapt to different fabric characteristics; 3. By rotatably installing the pressing structure on the swing arm, the pressing structure always has a tendency to move downward, so as to be able to press the fabric to make it unfold flatly. During the winding process of the fabric, the pressure roller can move upward and deflect, so as to carry out a certain degree of buffering. With the provided detection member and pressure sensor, the tension of the fabric can be observed in real time to avoid damage during the pressure process. Description of the drawings

Specific embodiments

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0018] Refer to Figures 1-8 , a textile winding device with a loosening prevention function, including a frame 1. The upper part of the rear half of the frame 1 is rotatably installed with a main shaft 11 through a bearing seat. The main shaft 11 is connected to the output end of an external driving device for rotating the main shaft 11. An electromagnetic brake is also installed on the output end of the driving device, so that the main shaft 11 will not deflect when the driving device stops. A expanding and contracting reel 2 is fixed on the main shaft 11, a material roller 21 is installed on the expanding and contracting reel 2, a reducer 5 is installed on the frame 1, and the input end of the reducer 5 is connected to the main shaft 11 through a belt pulley 12 and a toothed belt; On the right side of the front half of the frame 1, a side frame 3 is fixedly installed. On the left side of the side frame 3, a pressure compensation mechanism 4 is installed. The output end of the speed reducer 5 is connected to the pressure compensation mechanism 4. Two sets of adjusting members 6 are symmetrically distributed front and back on the pressure compensation mechanism 4. Two sets of swing arms 7 are symmetrically installed front and back on the right side of the side frame 3. The adjusting member 6 is slidably connected to the swing arm 7. A pressing structure 8 is rotatably installed between the two sets of swing arms 7.

[0019] Referring to Figures 2-5 , the pressure compensation mechanism 4 includes two thickening plates 43 symmetrically fixed at the front and rear ends on the left side of the side frame 3. A compensating member is slidably installed up and down on the thickening plate 43. Two reset members are installed on the compensating member away from the speed reducer 5. A driving member 41 is installed on the frame 1. The driving member 41 is connected to the compensating member.

[0020] The driving member 41 includes an output shaft 411 rotatably installed on the frame 1 through a bearing seat. The rear end of the output shaft 411 is connected to the output end of the speed reducer 5 through a coupling. Two sets of gears 412 are installed on the output shaft 411; The compensating member includes two sets of lifting plates 413 symmetrically distributed. On the side of the lifting plate 413 close to the gear 412, a lifting tooth 414 is provided. The lifting teeth 414 on the two sets of lifting plates 413 are respectively engaged with the two gears 412. One reinforcing column is respectively fixed on the upper and lower sides between the two lifting plates 413; The speed reducer 5 selects a suitable meshing three-stage reduction gear set according to actual needs. The reduction ratio of this speed reducer 5 is set to 1 / n. Among them, the transmission ratio between the main shaft 11 and the input end of the speed reducer 5 is 1. In this way, the transmission ratio between the speed reducer 5 and the main shaft 11 is n. Thus, for every n rotations of the material roller 21, that is, after the fabric is wound n times, the output shaft 411 rotates one circle, and the lifting plate 413 rises a certain height accordingly.

[0021] Referring to Figures 4-6 , two sets of symmetrically distributed rectangular grooves 431 are opened at the upper and lower ends on the left side of the thickening plate 43. The cross-section of the rectangular groove 431 is of a convex structure. Specifically, a groove opening of a convex structure is formed by penetrating the thickening plate 43 left and right. Then, the thickening plate 43 is fixed to the left side of the side frame 3 by screws, and a long strip is embedded in the groove opening. The long strip is fixed to the side frame 3 by screws, and the rectangular groove 431 can be formed; On the side of the lifting plate 413 close to the side frame 3, two sets of guide wheels 415 are symmetrically installed up and down and rotatably. The two guide wheels 415 are respectively placed in the corresponding rectangular grooves 431 in a rolling manner. A shaft pin is provided on the guide wheel 415. The shaft pin is fixed to the lifting plate 413 by screws. The cross-sections of the shaft pin and the guide wheel 415 are of a convex structure. The outer surface of the outer ring of the guide wheel 415 is in rolling contact with the surface of the long strip and the inner wall of the groove opening. When the lifting plate 413 moves up and down, it can move along the rectangular groove 431, so as to guide the lifting plate 413, and the lifting plate 413 will not be separated from the connection with the thickening plate 43.

[0022] A pressure-receiving plate 42 is welded to the left side of the front thickened plate 43. A lifting strip hole 421 is formed through the pressure-receiving plate 42 from front to back. The reset member includes a fixed straight plate 44 that is screw-fixed to the front lifting plate 413. A straight rod 443 is screw-fixed to the fixed straight plate 44. The front end of the straight rod 443 passes through the lifting strip hole 421 and is placed on the front side of the pressure-receiving plate 42. A dial 442 is fixed to the front end of the straight rod 443. A circular ring 444 is slidably sleeved on the straight rod 443. The circular ring 444 is located on the rear side of the pressure-receiving plate 42. A compression spring 441 is sleeved on the straight rod 443. The two ends of the compression spring 441 are respectively abutted against the fixed straight plate 44 and the circular ring 444. The compression spring 441 makes the fixed straight plate 44 always tend to move backward, and thus makes the lifting plate 413 tend to move backward; When the lifting plate 413 is at the lowest position, the compression spring 441 will push the lifting plate 413 and the guide wheel 415 to move backward along the bottom end of the return groove 431. The guide wheel 415 is placed at the rearmost side below the return groove 431. At this time, the gear 412 is engaged with the lifting tooth 414. After that, when the output shaft 411 drives the gear 412 to rotate, the rotating gear 412 will make the lifting plate 413 move upward by a corresponding distance under the action of the lifting tooth 414. During the upward movement of the lifting plate 413, the guide wheel 415 is in the rear part of the return groove 431, which can ensure the straight lifting of the lifting plate 413 without deviation; When the lifting plate 413 is at the highest position, the fabric wound on the material roller 21 needs to be replaced to the greatest extent. At this time, the bottom end of the outer ring of the guide wheel 415 is tangent to the top surface of the long strip. Pull the straight rod 443 backward through the dial 442 to make the guide wheel 415 be on the front side of the return groove 431. The lifting tooth 414 on the lifting plate 413 is disengaged from the engagement with the gear 412. At this time, the compression spring 441 is in a compressed state. Then, move the lifting plate 413 downward to the greatest extent through the dial 442, and then push the dial 442 inward, and the lifting tooth 414 on the lifting plate 413 can be engaged with the gear 412 again.

[0023] Refer to Figure 7 、 Figure 8 As shown in FIGS. A straight chute 621 is formed through the fixing plate 62 from front to back. On the side of the adjusting plate 61 facing the fixing plate 62, a straight slider 612 is provided. The straight slider 612 is slidably inserted into the straight chute 621. A locking bolt 613 is fixed on the straight slider 612. The locking bolt 613 passes through the straight chute 621 and is placed outside the fixing plate 62. And a locking nut is connected to the locking bolt 613. Loosening the locking nut can make the adjusting plate 61 move linearly left and right along the straight chute 621 on the fixing plate 62. After moving to the required position, tightening the locking nut can fix the adjusting plate 61.

[0024] Refer to Figure 7 、 Figure 8 The swing arm 7 includes two mounting shaft seats 71 symmetrically fixed on the right surface of the side frame 3 from front to back. A lever 72 is rotatably mounted between the two mounting shaft seats 71 through a rotating shaft. An adjusting chute 721 is formed through the lever 72 from front to back. At one end of the adjusting plate 61 away from the straight slider 612, an adjusting slide bar 611 is provided. The adjusting slide bar 611 is slidably inserted into the adjusting chute 721. For different fabrics, such as cotton, chemical fiber, silk, etc., their thickness, elasticity, and friction are all different. Fabrics with large elasticity may require a larger initial angle to compensate for elastic deformation, while thinner fabrics may require a smaller angle to avoid excessive compression. For brittle fabrics such as carbon fiber prepreg, too large an initial pressure angle will cause fiber breakage. Therefore, the initial pressure needs to be adjusted when dealing with fabrics of different materials. When the adjusting slide bar 611 moves to the right under the action of the adjusting plate 61, the adjusting slide bar 611 can push the lever 72 to deflect upward with the rotating shaft as the axis, thereby increasing the initial pressure angle. On the contrary, it deflects downward, and can finely calibrate the initial angle of the swing arm 7 to a certain extent to adapt to the characteristics of different fabrics.

[0025] The pressing structure 8 includes two side arms 81. Two pressing rollers 82 are rotatably mounted between the two side arms 81. On the upper side of the inner side of the side arm 81, a mounting pin 85 is fixed. The two side arms 81 are respectively rotatably connected to the two levers 72 through the mounting pins 85. A torsion spring 86 is sleeved on the mounting pin 85. One end of the torsion spring 86 is fixed to the side arm 81, and the other end of the torsion spring 86 is fixed to the lever 72. The torsion spring 86 makes the two side arms 81 always have a tendency to move downward, so that the fabric between the two pressing rollers 82 has a tendency to move downward, making the fabric taut.

[0026] A pressure sensor 84 is installed on the front arm 72. The front mounting pin 85 is designed with an extended length and is located in front of the front side arm 81. A detection member 83 is installed at the front end of the mounting pin 85. A part of the arc-shaped structure of the detection member 83 close to the pressure sensor 84 forms a detection arc surface 831. The detection arc surface 831 contacts the detection head of the pressure sensor 84. The pressure sensor 84 is a digital display pressure sensor that can directly display the pressure value. The radian of the detection arc surface 831 gradually increases from bottom to top. That is, the detection arc surface 831 is regarded as composed of countless points. The distance between the lowest point and the axis of the mounting pin 85 is the smallest, and the distance between the highest point and the axis of the mounting pin 85 is the largest. In this way, as more and more fabric is wound on the material roller 21, without changing the deflection angle of the swing arm 7, the pressure value between the fabric and the pressure roller 82 becomes larger and larger. The side arm 81 will be lifted, the detection member 83 will deflect accordingly, and the contact position between the detection arc surface 831 and the pressure sensor 84 changes, so that the pressure value can be detected.

[0027] Working principle: In the initial stage, the lifting plate 413 is at the lowest position. The lifting teeth 414 on the lifting plate 413 are engaged with the gear 412. The guide wheel 415 on the right side of the lifting plate 413 is at the lowest position and at the rear side of the loop groove 431. Unroll the fabric on the uncoiler and pass it through between the two pressure rollers 82 and wind it on the material roller 21, and then adjust the pressure of the pressure roller 82 on the fabric through the adjusting member 6 to make the pressure roller 82 at the most suitable pressure angle. Specifically, loosen the lock nut on the lock bolt 613, and the adjusting plate 61 can move linearly left and right along the linear sliding groove 621 on the fixing plate 62. During the movement, as the adjusting plate 61 and the adjusting slide bar 611 move left and right, the side arm 81 will also deflect accordingly. When the adjusting slide bar 611 moves to the right, the side arm 81 will be lifted. When the adjusting slide bar 611 moves to the left, the side arm 81 will deflect downward. The detection member 83 fixed to the side arm 81 will deflect accordingly, and the contact position between the detection arc surface 831 and the pressure sensor 84 changes, so that the pressure value can be detected. Observe the numerical change on the pressure sensor 84 to make it within a suitable pressure value. After the pressure value increases to a certain extent, that is, the pressure borne by the fabric after winding n circles, and it is still within the maximum pressure value that the fabric can bear, then tighten the lock nut to fix the adjusting plate 61, and the initial pressure angle adjustment can be completed. At this time, the fabric is also in a tensioned state and will not become loose or wrinkled during subsequent winding.

[0028] After that, the power supply of the driving device can be turned on. The driving device drives the main shaft 11 to rotate. The rotating main shaft 11 will cause the expanding and contracting drum 2 and the material roller 21 to rotate, so that the fabric is wound on the material roller 21. As the fabric is wound on the material roller 21, the winding thickness will gradually increase, and the tension of the pressure roller 82 on the fabric will gradually increase. The tension between the pressure roller 82 and the fabric is maintained within the maximum range that the fabric can bear, and the fabric will not be damaged; After the fabric is wound n circles, the tension between the pressure roller 82 and the fabric is relatively large. Since the main shaft 11 is connected to the reduction gear 5, and the reduction gear 5 is connected to the output shaft 411, and the transmission ratios between the output shaft 411, the reduction gear 5 and the main shaft 11 are n:1:1. Therefore, after the fabric is wound n circles, the output shaft 411 and the gear 412 will rotate one circle, and the gear 412 will cause the lifting plate 413 to rise by a unit distance. The adjusting member 6 connected to the lifting plate 413 will also rise accordingly. During the rising process of the adjusting member 6, the adjusting slide rod 611 on the adjusting plate 61 can push the arm rod 72 to deflect upward with the axis of the rotating shaft, thereby increasing the pressure angle and reducing the tension between the pressure roller 82 and the fabric; In this way, the cycle repeats. After the fabric is wound n circles each time, the adjusting member 6 rises by a height unit, and then the swing arm 7 drives the pressure roller 82 to deflect upward by a certain angle for pressure compensation, so that the fabric tension is maintained within the optimal range. In the subsequent winding process, the tension can always be guaranteed to be constant, the pressure fluctuation of the pressure roller 82 is reduced, the winding tightness and uniformity of the fabric are improved, and the fabric fibers will not be strained due to excessive tension.

[0029] When the adjusting member 6 rises to the maximum height under the action of the lifting plate 413, the winding of the fabric on the material roller 21 is also completed, and the material roller 21 needs to be replaced. At this time, the bottom end of the outer ring of the guide wheel 415 is tangent to the top surface of the long strip. Pull the straight rod 443 backward through the dial 442, so that the guide wheel 415 is located in front of the loop groove 431. The lifting teeth 414 on the lifting plate 413 are disengaged from the gear 412. At this time, the compression spring 441 is in a compressed state. Then, move the lifting plate 413 downward to the maximum extent through the dial 442, and then push the dial 442 inward, so that the lifting teeth 414 on the lifting plate 413 can be engaged with the gear 412 again, enabling the entire pressure compensation mechanism 4 to quickly reset and improving the winding replacement efficiency.

[0030] By providing a pressure compensation mechanism 4 on the rewinding device, which is connected to the main shaft 11 of the rewinding device through a speed reducer 5, and the transmission ratios among the three are allocated as required. After the rewinding device winds a certain thickness of fabric, the pressure compensation mechanism 4 can make the pressing structure 8 deflect upward by a certain angle for pressure compensation, so that the fabric tension is maintained within the optimal range. In this way, during the subsequent rewinding process, the constancy of the tension can be always ensured, improving the winding tightness and uniformity of the fabric, and preventing the fabric fibers from being strained due to excessive tension. An adjusting member 6 is provided on the pressure compensation mechanism 4. The adjusting member 6 is movably connected to the swing arm 7. The adjusting member 6 can push the arm rod 72 to deflect upward or downward with the axis of the rotating shaft, and can finely calibrate the initial angle of the swing arm 7 to a certain extent, thereby increasing or decreasing the initial pressure angle to adapt to different fabric characteristics. By rotatably mounting the pressing structure 8 on the swing arm 7, the pressing structure 8 always has a tendency to move downward, and thus can press the fabric to make it flat and unfolded. During the rewinding process of the fabric, the pressure roller 82 can move upward and deflect, so as to perform a certain degree of buffering, reduce the pressure fluctuation of the pressure roller 82, and cooperate with the provided detection member 83 and pressure sensor 74 to be able to observe the tension of the fabric in real time and avoid damage caused by the pressure process.
