Description

Technical Field

[0001] The present application relates to the technical field of textile machinery, and particularly relates to a fabric conveying device and a fabric winding method. Background Art

[0002] In the field of textile machinery, fabric transmission is an important process. The fabric transmission process affects the quality of the wound fabric. Generally, there are two main factors that affect the quality of fabric winding. One is that the fabric will shift during the transmission process, resulting in the winding roller being unable to wind the fabric neatly. The fabric shift will cause wrinkles at the edge of the fabric, unable to meet the requirements of the finished roll size. In severe cases, the shift will cause the interruption of the conveying process, and manual adjustment is time-consuming and laborious. The other is that during the fabric conveying process, the tension of the fabric will fluctuate. Excessive tension will cause the fabric to stretch and deform, and too small tension will cause the fabric to wrinkle or shift. In the prior art, for the tension adjustment structure, the tension adjustment has a lag, and it is also unable to compensate for the tension fluctuation caused by the deviation rectifying device during the deviation rectifying process, and it is unable to keep the fabric conveying at a constant tension, resulting in low product winding efficiency and high rejection rate. Summary of the Invention

[0003] The present invention aims to provide a technical solution to solve the above problems in order to overcome the above deficiencies.

[0004] A fabric conveying device includes a feeding unit, a deviation rectifying unit, a tension adjusting unit, a flattening unit, a winding unit and a controller; the feeding unit is used for installing a feeding roller and continuously feeding; the wrinkle deviation rectifying device, the wrinkle deviation rectifying device includes a wrinkle deviation rectifying bracket, on which three wrinkle deviation rectifying rollers are sequentially rotatably connected. The wrinkle deviation rectifying roller includes an outer roller and an inner roller shaft. The outer roller covers the inner roller shaft. A plurality of through holes are arranged on the outer roller. A plurality of spring grooves corresponding to the positions of the through holes are arranged on the outer peripheral side of the inner roller shaft. A telescopic spring is fixedly installed in the spring groove. The top end of the telescopic spring is fixedly installed with a top bead. The diameter of the top bead is larger than the diameter of the through hole. The top end of the top bead extends out of the through hole; the plurality of through holes are symmetrically and equidistantly arranged in a "V" shape on the development view of the outer peripheral side of the outer roller; a dye tank is arranged between the feeding unit and the wrinkle deviation rectifying device; the deviation rectifying unit includes a first deviation rectifying mechanism and a second deviation rectifying mechanism. The first deviation rectifying mechanism and the second deviation rectifying mechanism are sequentially arranged and can select to enable the first deviation rectifying mechanism or the second deviation rectifying mechanism according to the deviation direction of the fabric; the tension adjusting unit includes an active tension adjusting mechanism and a passive tension adjusting mechanism. Among them, the passive tension adjusting mechanism includes a tension detection element, and the active tension adjusting mechanism can actively adjust the fabric tension according to the fabric tension feedback by the tension detection element; the flattening unit includes a flattening mechanism and an electrostatic eliminating mechanism. The flattening mechanism is used for flattening the fabric; the electrostatic eliminating mechanism is used for eliminating the static electricity of the fabric; the winding unit is used for placing a winding roller and continuously winding; the controller is electrically connected to the feeding unit, the deviation rectifying unit, the tension adjusting unit, the flattening unit and the winding unit.

[0005] Among them, the feeding unit (1), the deviation rectifying unit (2), the tension adjusting unit (3), the flattening unit (4) and the winding unit (5) can all be realized by a variable frequency integrated machine. Thus, during the fabric conveying process, the slip rate of the motors on both sides of the fabric, the transmission speed on both sides of the fabric, the tension on both sides of the fabric, and the braking force on both sides of the fabric are synchronized on the ultra-micro mechanism.

[0006] The feeding unit, the deviation rectifying unit, the tension adjusting unit, the flattening unit and the winding unit are electrically connected.

[0007] Among them, the feeding unit, the deviation rectifying unit, the tension adjusting unit, the flattening unit and the winding unit are sequentially arranged. The fabric is released from the feeding unit and sequentially passes through the deviation rectifying unit, the tension adjusting unit and the flattening unit, and is wound by the winding unit to finally obtain a finished roll. Since the plurality of through holes and spring grooves are symmetrically and equidistantly arranged in a "V" shape on the development view of the outer peripheral sides of the outer roller and the inner roller shaft, during the contact process of the top bead with the fabric, the process of straightening the fabric by human hands is simulated. The top bead squeezes the fabric to both sides, realizing the automatic fabric straightening process, unfolding the wrinkles generated during the conveying process of the fabric, and preventing deviation.

[0008] Further, the deviation rectifying unit includes a deviation rectifying bracket, a first deviation rectifying mechanism and a second deviation rectifying mechanism fixedly arranged on the deviation rectifying bracket. The first deviation rectifying mechanism includes two first deviation rectifying cylinders fixedly arranged on the bottom side of the top cross beam of the deviation rectifying bracket. The first deviation rectifying cylinders are rotatably installed with first deviation rectifying pressure wheels through fixing blocks, and the controller is used to control the telescoping of the first deviation rectifying cylinders. The first deviation rectifying mechanism further includes a first deviation rectifying seat fixedly installed at the left bottom end of the deviation rectifying bracket. A roller groove is formed at the top end of the first deviation rectifying seat, and two first deviation rectifying rollers are rotatably installed in the roller groove. One end of a first deviation rectifying roller is fixedly installed with a first rotating shaft, a first sprocket is fixedly installed on the first rotating shaft, and one end of the first rotating shaft is fixedly installed with the output end of a first servo motor. The other end of the first deviation rectifying roller is installed with a second rotating shaft, and a second sprocket is fixedly installed on the second rotating shaft. The first sprocket and the second sprocket are connected by a chain drive. The first deviation rectifying cylinder has a transmission station for driving the bottom side of the first deviation rectifying pressure wheel to be higher than the top side of the first deviation rectifying roller and a deviation rectifying station for driving the bottom side of the first deviation rectifying pressure wheel to be lower than the top side of the first deviation rectifying roller. The axis direction of the first deviation rectifying roller forms an angle of 60° with the fabric conveying direction.

[0009] Among them, the first deviation rectifying mechanism and the second deviation rectifying mechanism are arranged in sequence and can respectively perform left / right deviation rectification on the fabric. The two first deviation rectifying cylinders in the first deviation rectifying mechanism have a transmission station for driving the bottom side of the first deviation rectifying pressure wheel to be higher than the top side of the first deviation rectifying roller and a deviation rectifying station for driving the bottom side of the first deviation rectifying pressure wheel to be lower than the top side of the first deviation rectifying roller. When the first deviation rectifying cylinder drives the first deviation rectifying pressure wheel to be in the transmission station, the fabric does not contact the first deviation rectifying roller. When the first deviation rectifying cylinder drives the first deviation rectifying pressure wheel to be in the deviation rectifying station, the first deviation rectifying pressure wheel presses down the fabric. Since the bottom side of the first deviation rectifying pressure wheel is lower than the first deviation rectifying roller at this time, the fabric is pressed on the top side of the first deviation rectifying roller. Since the axis direction of the first deviation rectifying roller forms an angle of 60° with the fabric conveying direction, the rotation of the first deviation rectifying roller performs left deviation rectification on the fabric.

[0010] Further, the second deviation rectifying mechanism includes two second deviation rectifying cylinders fixedly arranged on the bottom side of the top cross beam of the deviation rectifying bracket. The second deviation rectifying cylinders are rotatably installed with second deviation rectifying pressure wheels through fixing blocks, and the controller is used to control the telescoping of the second deviation rectifying cylinders. The second deviation rectifying mechanism further includes a second deviation rectifying seat fixedly installed at the right bottom end of the deviation rectifying bracket. A roller groove is formed at the top end of the second deviation rectifying seat, and two second deviation rectifying rollers are rotatably installed in the roller groove. The axis direction of the second deviation rectifying roller forms an angle of 60° with the fabric conveying direction, and the angle between the axis direction of the first deviation rectifying roller and the axis direction of the second deviation rectifying roller is 120°. The second deviation rectifying roller is driven by a second servo motor. The second deviation rectifying cylinder has a transmission station for driving the bottom side of the second deviation rectifying pressure wheel to be higher than the top side of the second deviation rectifying roller and a deviation rectifying station for driving the bottom side of the second deviation rectifying pressure wheel to be lower than the top side of the second deviation rectifying roller.

[0011] Among them, the two second rectifying cylinders in the second rectifying mechanism have a transmission station where the bottom side of the second rectifying pressure roller is higher than the top side of the second rectifying roller and a rectifying station where the bottom side of the second rectifying pressure roller is lower than the top side of the second rectifying roller. When the second rectifying cylinder drives the second rectifying pressure roller to be in the transmission station, the fabric does not contact the second rectifying roller. When the second rectifying cylinder drives the second rectifying pressure roller to be in the rectifying station, the second rectifying pressure roller presses down the fabric. Since the bottom side of the second rectifying pressure roller is lower than the second rectifying roller at this time, the fabric is pressed on the top side of the second rectifying roller. Since the included angle between the axis direction of the second rectifying roller and the fabric conveying direction is 60°, and the included angle between the axis direction of the first rectifying roller and the axis direction of the second rectifying roller is 120°, the rotation of the second rectifying roller corrects the fabric to the right.

[0012] Furthermore, a first guide roller and a fifth guide roller are respectively rotatably installed on the outer sides of the lower ends of the left and right side columns of the rectifying support through mounting frames, and a second guide roller and a fourth guide roller are respectively rotatably installed on the inner sides of the upper ends of the left and right side columns of the rectifying support through mounting frames. A third guide roller is arranged between the first rectifying pressure roller and the second rectifying pressure roller. The second guide roller, the third guide roller and the fourth guide roller are at the same height and higher than the first rectifying pressure roller and the second rectifying pressure roller.

[0013] Among them, the first guide roller, the second guide roller, the third guide roller, the fourth guide roller and the fifth guide roller are arranged in sequence from left to right. The arrangement of the five guide rollers facilitates the guiding of the fabric. At the same time, the second guide roller, the third guide roller and the fourth guide roller are at the same height. At the same time, the heights of the first rectifying pressure roller / second rectifying pressure roller and the first rectifying roller / second rectifying roller are both lower than the heights of the second guide roller, the third guide roller and the fourth guide roller, so that the first rectifying pressure roller / second rectifying pressure roller can press the fabric on the first rectifying roller / second rectifying roller.

[0014] Furthermore, fabric detection units are respectively fixedly installed on the two columns on the right side of the rectifying support. The fabric detection unit includes a U-shaped fixing frame and a photoelectric switch installed inside the U-shaped fixing frame.

[0015] Among them, the distance between the left photoelectric switch and the right photoelectric switch is greater than the width of the fabric, and the left photoelectric switch and the right photoelectric switch are facing the fabric. When the left photoelectric switch detects the fabric, it indicates that the fabric deviates to the left. The photoelectric switch is used to feedback the deviation signal to the controller, and the controller controls the second rectifying mechanism to straighten the fabric. Similarly, when the right photoelectric switch detects the fabric, it indicates that the fabric deviates to the right. The photoelectric switch is used to feedback the deviation signal to the controller, and the controller controls the first rectifying mechanism to straighten the fabric.

[0016] Further, the tension adjustment unit includes an active tension adjustment mechanism and a passive tension adjustment mechanism. The active tension adjustment mechanism includes an active tension adjustment bracket. A fixed plate is fixedly installed at the bottom end of the active tension adjustment bracket. Active tension adjustment rollers are rotatably installed at equal intervals at the top end of the fixed plate. Chutes are formed inside both sides of the active tension adjustment bracket. A movable plate is slidably installed in the chutes. Passive tension adjustment rollers are rotatably installed at equal intervals at the bottom end of the movable plate. The movable plate is fixedly installed at the output end of an electric push rod. The top end of the electric push rod is fixedly arranged on the active tension adjustment bracket. The passive tension adjustment mechanism includes a passive tension adjustment bracket. Telescopic sleeves are arranged at equal intervals and staggered up and down on the top end and the bottom end of the passive tension adjustment bracket. The telescopic sleeve includes a fixed sleeve and a telescopic rod. A spring is arranged between the fixed sleeve and the telescopic rod. A passive tension adjustment roller is rotatably installed at the top end of the telescopic rod. A sensor bracket is fixedly installed at the bottom left end of the passive tension adjustment bracket. A displacement sensor is fixedly installed at the top end of the sensor bracket. The displacement sensor faces the passive tension adjustment roller.

[0017] Among them, the passive tension adjustment mechanism includes telescopic sleeves arranged in a staggered manner up and down. A passive tension adjustment roller is rotatably installed at the top end of the telescopic sleeve. The spring arranged inside the telescopic sleeve can adapt to the tension change generated during the fabric conveying process, thereby adjusting the slight fluctuation of the fabric tension. A displacement sensor is arranged at the bottom left end of the passive tension adjustment bracket. When the displacement sensor detects that the displacement of the passive tension adjustment roller exceeds the preset distance, the active tension adjustment mechanism acts. The electric push rod of the active tension adjustment mechanism drives the movable plate to move up or down until the fabric tension is within the preset range. The active tension adjustment mechanism can adjust the large tension change of the fabric.

[0018] Further, the leveling unit includes a leveling bracket. The leveling bracket includes a leveling mechanism and an anti-static mechanism. The leveling mechanism includes a flattening roller and a driving motor for driving the flattening roller to rotate. The anti-static mechanism includes an electrostatic elimination roller and a metal wire connected to the electrostatic elimination roller. The metal wire is grounded. Symmetrically arranged helical lines are arranged on both the left and right sides of the roller body of the flattening roller. The helical lines on the left and right sides have opposite helix directions. The material of the electrostatic elimination roller is metal. A gap for the fabric to pass through is arranged between the electrostatic elimination roller and the flattening roller.

[0019] Among them, the electrostatic elimination roller and the flattening roller are arranged opposite to each other. A gap for the fabric to pass through is arranged between them. The gap is slightly smaller than the thickness of the fabric, so that when the fabric passes through the electrostatic elimination roller and the flattening roller, it can be fully flattened and the static electricity can be fully eliminated.

[0020] Furthermore, the material discharging unit comprises a material discharging bracket, a controller is fixedly installed on the top of the material discharging bracket, a material discharging roller is rotatably installed on the left side of the material discharging unit, and the material discharging roller is connected to the material discharging roller servo motor through a chain drive.

[0021] Furthermore, the material receiving unit includes a material receiving bracket, and a material receiving roller is rotatably installed on the right side of the material receiving roller bracket, and the material receiving roller is connected to the material receiving roller servo motor through a chain drive.

[0022] The present invention also includes a cloth winding method using a cloth conveying device, comprising the following steps:

[0023] S1: Place the fabric raw material roll on the unwinding roller, pass the fabric end through the first guide roller, the second guide roller, the third guide roller, the fourth guide roller, and the fifth guide roller in the deviation correction unit, and then pass through the tension adjustment unit and the leveling unit, and then wind it on the receiving roller of the receiving unit, wind it 2-3 times and fix it;

[0024] S2: Synchronously start the servo motor of the unloading roller and the servo motor of the receiving roller. When the cloth detection unit detects that the cloth is deflected to the left, the controller controls the two first deflection correcting cylinders to move downward, so that the first deflection correcting cylinders change from the transmission station to the deflection correcting station. When the cloth detection unit detects that the cloth is back to the original position, the controller controls the two first deflection correcting cylinders to move upward, so that the first deflection correcting cylinders change from the deflection correcting station to the transmission station. When the cloth detection unit detects that the cloth is deflected to the right, the controller controls the two second deflection correcting cylinders to move downward, so that the second deflection correcting cylinders change from the transmission station to the deflection correcting station. When the cloth detection unit detects that the cloth is back to the original position, the controller controls the two second deflection correcting cylinders to move upward, so that the second deflection correcting cylinders change from the deflection correcting station to the transmission station.

[0025] S3: In step S2, when the first correcting cylinder or the second correcting cylinder moves from downward to touching the fabric and then continues to move downward to the correcting station, the controller controls the electric push rod to synchronously drive the movable plate to move upward; when the first correcting cylinder or the second correcting cylinder moves upward from the correcting station to being separated from the fabric, the controller controls the electric push rod to synchronously drive the movable plate to move downward;

[0026] S4: When the displacement sensor detects that the position of the tension adjustment roller has changed, the displacement sensor feeds back the position change signal to the controller, and the controller converts the position change signal into a fabric tension change signal. The controller controls the action of the electric push rod through the fabric tension change signal, and the electric push rod drives the movable plate to move upward or downward until the fabric tension is in a preset range.

[0027] S5: When step S3 and step S4 are triggered at the same time, step S3 is executed first;

[0028] S6: After the winding of the receiving unit is completed, unload the finished roll and store it in the warehouse.

[0029] Among them, the operation of step S3 enables the tension adjustment unit and the deviation correction unit to act in coordination. Since the deviation correction unit will cause the fabric to be instantaneously tensioned or relaxed when it acts, resulting in a large change in the fabric tension. At this time, the tension adjustment unit acts synchronously, that is, it synchronously relaxes or tensions the fabric instantaneously to make up for the tensioning or relaxing amount of the deviation correction unit to the fabric, so as to maintain the stability of the fabric tension.

[0030] In step S4, the displacement sensor detects that the position change of the tension adjustment roller has a preset value. When the position change of the tension adjustment roller is less than the preset value, only slight fluctuations occur in the surface fabric tension. At this time, the controller does not issue an action command to the electric push rod. When the position change of the tension adjustment roller is greater than the preset value, the controller issues an action command to the electric push rod.

[0031] When steps S3 and S4 are triggered simultaneously, the sudden large change in the fabric tension is caused by step S3. Therefore, step S3 is preferentially performed.

[0032] After the present invention adopts the above technical solutions, compared with the prior art, it has the following advantages:

[0033] (1) The deviation correction unit provided in the present application includes a first deviation correction mechanism and a second deviation correction mechanism, which can flexibly select to enable the first deviation correction mechanism or the second deviation correction mechanism according to the deviation correction needs. When deviation correction is not required, the deviation correction mechanism does not contact the fabric, avoiding the influence of the deviation correction mechanism on the fabric conveying tension during the normal fabric conveying process; through the inclined first deviation correction roller / second deviation correction roller, the offset fabric can be quickly corrected, and the inclined deviation correction roller has a component in the same direction as the fabric conveying direction, and the deviation correction means is gentle, avoiding the generation of wrinkles on the fabric during the deviation correction process.

[0034] (2) The tension adjustment unit provided in the present application includes an active tension adjustment mechanism and a passive tension adjustment mechanism. Among them, the passive tension adjustment mechanism is staggered with telescopic sleeves, and a passive tension adjustment roller is rotatably installed at the top of the telescopic sleeve. Through the spring in the telescopic sleeve, it can adapt to the tension change generated during the fabric conveying process, thereby adjusting the slight fluctuation of the fabric tension; a displacement sensor is provided at the left bottom end of the passive tension adjustment bracket. When the displacement sensor detects that the displacement of the passive tension adjustment roller exceeds the preset distance, the active tension adjustment mechanism acts, and the electric push rod of the active tension adjustment mechanism drives the movable plate to move up or down until the fabric tension is within the preset range. The tension adjustment unit adopts a combination of a tension adjustment mechanism and a passive tension adjustment mechanism. The passive tension adjustment mechanism can self-adjust the slight fluctuation of the fabric tension, avoiding the frequent action of the active tension adjustment mechanism. At the same time, the active tension adjustment mechanism can adjust the large tension change of the fabric.

[0035] (3) The active tension adjustment mechanism of the present application can cooperate with the correction unit. When the first correction cylinder or the second correction cylinder in the correction unit moves from downward to touching the cloth and then continues to move downward to the correction station, the controller controls the electric push rod to synchronously drive the movable plate to move upward; when the first correction cylinder or the second correction cylinder moves upward from the correction station to detaching from the cloth, the controller controls the electric push rod to synchronously drive the movable plate to move downward; when the first correction cylinder or the second correction cylinder moves from downward to touching the cloth and then continues to move downward to the correction station, the cloth will be rapidly tensioned. At this time, the electric push rod is controlled to synchronously drive the movable plate to move upward, so that the cloth is synchronously relaxed. At the same time, the controller controls the cloth tension amount to be equal to the cloth relaxation amount, so as to keep the cloth tension stable at all times.

[0036] (4) The flattening unit provided in the present application includes a flattening mechanism and an anti-static mechanism. The flattening unit is adjacent to the material receiving unit, so that the fabric is kept flat before being rolled up, and static electricity is eliminated at the same time, thereby further ensuring the quality of the finished fabric test roll.

[0037] (5) The present invention automatically maintains symmetrical feeding of the fabric, automatically eliminates wrinkles, prevents fabric deviation, and automatically corrects the fabric by means of symmetrically and evenly distributed protruding top beads on the wrinkle correction roller.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0050] Please refer to Figure 1, the present invention provides a technical solution: a fabric conveying device, including a feeding unit 1, a deviation rectifying unit 2, a tension adjusting unit 3, a flattening unit 4, a winding unit 5 and a controller 6; the feeding unit 1 is used for installing a feeding roller and continuously feeding the fabric; the deviation rectifying unit 2 includes a first deviation rectifying mechanism and a second deviation rectifying mechanism, which are arranged in sequence and can select to enable the first deviation rectifying mechanism or the second deviation rectifying mechanism according to the deviation direction of the fabric; the tension adjusting unit 3 includes an active tension adjusting mechanism and a passive tension adjusting mechanism. Among them, the passive tension adjusting mechanism includes a tension detecting element, and the active tension adjusting mechanism can actively adjust the fabric tension according to the fabric tension fed back by the tension detecting element; the flattening unit 4 includes a flattening mechanism and an anti-static mechanism, the flattening mechanism is used for flattening the fabric; the anti-static mechanism is used for eliminating the static electricity of the fabric; the winding unit 5 is used for placing a winding roller and continuously winding the fabric; the controller 6 is electrically connected to the feeding unit 1, the deviation rectifying unit 2, the tension adjusting unit 3, the flattening unit 4 and the winding unit 5 respectively.

[0051] Among them, the feeding unit 1, the deviation rectifying unit 2, the tension adjusting unit 3, the flattening unit 4 and the winding unit 5 can all be realized by a variable frequency integrated machine. Thus, during the fabric conveying process, the slip rate of the motors on both sides of the fabric, the transmission speed on both sides of the fabric, the tension on both sides of the fabric, and the braking force on both sides of the fabric are synchronized on the ultra-micro mechanism. Specifically, the feeding unit 1, the deviation rectifying unit 2, the tension adjusting unit 3, the flattening unit 4, and the winding unit 5 are arranged in sequence. The fabric is released from the feeding unit 1 and passes through the deviation rectifying unit 2, the tension adjusting unit 3, and the flattening unit 4 in sequence, and is wound by the winding unit 5 to finally obtain a finished roll. Among them, the deviation rectifying unit 2 can select to enable the first deviation rectifying mechanism or the second deviation rectifying mechanism according to needs.

[0053] Specifically, since multiple through holes 54 and spring grooves 55 are arranged symmetrically and equidistantly in a "V" shape on the unfolded view of the outer layer roller 53 and the inner roller 54, during the contact between the top beads 57 and the fabric, the process of arranging the fabric by hand is simulated. The top beads 57 push the fabric to both sides, realizing the automatic fabric arranging process, unfolding the wrinkles generated during the transportation of the fabric, and preventing deviation. When the fabric deviates, there are overlaps and wrinkles on the side edge of the fabric after it comes out. While eliminating the wrinkles, the wrinkle correction device 50 automatically maintains the symmetrical feeding of the fabric, preventing the overall deviation of the fabric and realizing automatic deviation correction.

The controller 6 is used to control the telescoping of the first deviation correction cylinders 12; the first deviation correction mechanism further includes a first deviation correction seat 14 fixedly installed at the left bottom end of the deviation correction bracket 11. A roller groove is opened at the top end of the first deviation correction seat 14, and two first deviation correction rollers 15 are rotatably installed in the roller groove.

The other end of the first deviation correction roller 15 is installed with a second rotating shaft, and a second sprocket 17 is fixedly installed on the second rotating shaft. The first sprocket 16 and the second sprocket 17 are connected through a chain drive; the first deviation correction cylinder 12 has a transmission station for driving the bottom side of the first deviation correction pressure wheel 13 to be higher than the top side of the first deviation correction roller 15 and a deviation correction station for driving the bottom side of the first deviation correction pressure wheel 13 to be lower than the top side of the first deviation correction roller 15. The axial direction of the first deviation correction roller 15 forms an angle of 60° with the fabric conveying direction.

[0057] Among them, the first deviation rectifying mechanism and the second deviation rectifying mechanism are arranged in sequence, and can respectively perform left / right deviation rectification on the fabric. The two first deviation rectifying cylinders 12 in the first deviation rectifying mechanism have a transmission station for driving the bottom side of the first deviation rectifying pressure wheel 13 to be higher than the top side of the first deviation rectifying roller 15 and a deviation rectifying station for driving the bottom side of the first deviation rectifying pressure wheel 13 to be lower than the top side of the first deviation rectifying roller 15. When the first deviation rectifying cylinder 12 drives the first deviation rectifying pressure wheel 13 to be in the transmission station, the fabric does not contact the first deviation rectifying roller 15. When the first deviation rectifying cylinder 12 drives the first deviation rectifying pressure wheel 13 to be in the deviation rectifying station, the first deviation rectifying pressure wheel 13 presses down the fabric. Since the bottom side of the first deviation rectifying pressure wheel 13 is lower than the first deviation rectifying roller 15 at this time, the fabric is pressed on the top side of the first deviation rectifying roller 15. Since the included angle between the axial direction of the first deviation rectifying roller 15 and the fabric conveying direction is 60°, the first deviation rectifying roller 15 rotates to perform left deviation rectification on the fabric.

[0058] Please refer to Figures 5-7 , the second deviation rectifying mechanism includes two second deviation rectifying cylinders 19 fixedly arranged at the bottom side of the top cross beam of the deviation rectifying support 11. The second deviation rectifying cylinders 19 are rotatably installed with second deviation rectifying pressure wheels 20 through fixing blocks. The controller 6 is used to control the telescoping of the second deviation rectifying cylinders 19. The second deviation rectifying mechanism further includes a second deviation rectifying seat 21 fixedly installed at the right bottom end of the deviation rectifying support 11. The top end of the second deviation rectifying seat 21 is provided with a roller groove, and two second deviation rectifying rollers 22 are rotatably installed in the roller groove. Among them, the included angle between the axial direction of the second deviation rectifying roller 22 and the fabric conveying direction is 60°, and the included angle between the axial direction of the first deviation rectifying roller 15 and the axial direction of the second deviation rectifying roller 22 is 120°. The second deviation rectifying roller 22 is driven by a second servo motor 23. The second deviation rectifying cylinders 19 have a transmission station for driving the bottom side of the second deviation rectifying pressure wheel 20 to be higher than the top side of the second deviation rectifying roller 22 and a deviation rectifying station for driving the bottom side of the second deviation rectifying pressure wheel 20 to be lower than the top side of the second deviation rectifying roller 22.

[0059] Among them, the two second deviation rectifying cylinders 19 in the second deviation rectifying mechanism have a transmission station for driving the bottom side of the second deviation rectifying pressure wheel 20 to be higher than the top side of the second deviation rectifying roller 22 and a deviation rectifying station for driving the bottom side of the second deviation rectifying pressure wheel 20 to be lower than the top side of the second deviation rectifying roller 22. When the second deviation rectifying cylinder 19 drives the second deviation rectifying pressure wheel 20 to be in the transmission station, the fabric does not contact the second deviation rectifying roller 22. When the second deviation rectifying cylinder 19 drives the second deviation rectifying pressure wheel 20 to be in the deviation rectifying station, the second deviation rectifying pressure wheel 20 presses down the fabric. Since the bottom side of the second deviation rectifying pressure wheel 20 is lower than the second deviation rectifying roller 22 at this time, the fabric is pressed on the top side of the second deviation rectifying roller 22. Since the included angle between the axial direction of the second deviation rectifying roller 22 and the fabric conveying direction is 60°, and the included angle between the axial direction of the first deviation rectifying roller 15 and the axial direction of the second deviation rectifying roller 22 is 120°, the second deviation rectifying roller 22 rotates to perform right deviation rectification on the fabric.

[0060] The deviation-correcting roller arranged obliquely has a component in the same direction as the fabric conveying direction. The deviation-correcting means is gentle, avoiding the relative movement in the vertical direction between the deviation-correcting roller and the fabric directly, and avoiding the generation of wrinkles on the fabric during deviation correction.

[0061] Please refer to Figures 5-7 , at the outer sides of the lower ends of the left and right side columns of the deviation-correcting bracket 11, a first guide roller 24 and a fifth guide roller 28 are respectively rotatably installed through mounting brackets. At the inner sides of the upper ends of the left and right side columns of the deviation-correcting bracket 11, a second guide roller 25 and a fourth guide roller 27 are respectively rotatably installed through mounting brackets. A third guide roller 26 is arranged between the first deviation-correcting pressure wheel 13 and the second deviation-correcting pressure wheel 20. The second guide roller 25, the third guide roller 26, and the fourth guide roller 27 are at the same height and are higher than the first deviation-correcting pressure wheel 13 and the second deviation-correcting pressure wheel 20.

[0062] Among them, the first guide roller 24, the second guide roller 25, the third guide roller 26, the fourth guide roller 27, and the fifth guide roller 28 are arranged in sequence from left to right. The arrangement of the five guide rollers facilitates the guiding of the fabric. At the same time, the second guide roller 25, the third guide roller 26, and the fourth guide roller 27 are at the same height. At the same time, the heights of the first deviation-correcting pressure wheel 13 / the second deviation-correcting pressure wheel 20 and the first deviation-correcting roller 15 / the second deviation-correcting roller 22 are both lower than the heights of the second guide roller 25, the third guide roller 26, and the fourth guide roller 27, so that the first deviation-correcting pressure wheel 13 / the second deviation-correcting pressure wheel 20 can press the fabric onto the first deviation-correcting roller 15 / the second deviation-correcting roller 22.

[0063] Please refer to Figure 7 , on the two columns on the right side of the deviation-correcting bracket 11, fabric detection units are respectively fixedly installed. The fabric detection unit includes a U-shaped fixing bracket 29 and a photoelectric switch 30 installed inside the U-shaped fixing bracket 29.

[0064] Among them, the distance between the left photoelectric switch 30 and the right photoelectric switch 30 is greater than the width of the fabric, and the left photoelectric switch 30 and the right photoelectric switch 30 face the fabric directly. When the left photoelectric switch 30 detects the fabric, it indicates that the fabric deviates to the left. The photoelectric switch 30 is used to feedback the deviation signal to the controller 6, and the controller 6 controls the second deviation-correcting mechanism to straighten the fabric; similarly, when the right photoelectric switch 30 detects the fabric, it indicates that the fabric deviates to the right. The photoelectric switch 30 is used to feedback the deviation signal to the controller 6, and the controller 6 controls the first deviation-correcting mechanism to straighten the fabric.

[0065] Please refer to Figure 8, the tension adjustment unit 3 includes an active tension adjustment mechanism and a passive tension adjustment mechanism. The active tension adjustment mechanism includes an active tension adjustment bracket 31. At the bottom end of the active tension adjustment bracket 31, a fixed plate 33 is fixedly installed. At the top end of the fixed plate 33, active tension adjustment rollers 32 are rotatably installed at equal intervals. In the inner sides of both sides of the active tension adjustment bracket 31, chutes are opened. In the chutes, movable plates 34 are slidably installed. At the bottom end of the movable plates 34, active tension adjustment rollers 32 are rotatably installed at equal intervals. The movable plates 34 are fixedly installed at the output ends of electric push rods 35. The top ends of the electric push rods 35 are fixedly arranged on the active tension adjustment bracket 31; the passive tension adjustment mechanism includes a passive tension adjustment bracket 36. Telescopic sleeves 37 are arranged at the top end and the bottom end of the passive tension adjustment bracket 36 at equal intervals and staggered. The telescopic sleeve 37 includes a fixed sleeve 38 and a telescopic rod 39. A spring 40 is arranged between the fixed sleeve 38 and the telescopic rod 39. At the top end of the telescopic rod 39, a passive tension adjustment roller 41 is rotatably installed; at the left bottom end of the passive tension adjustment bracket 36, a sensor bracket 42 is fixedly installed. At the top end of the sensor bracket 42, a displacement sensor 43 is fixedly installed. The displacement sensor is directly opposite to the passive tension adjustment roller 41.

[0066] Among them, the passive tension adjustment mechanism includes telescopic sleeves 37 arranged in a staggered manner up and down. At the top end of the telescopic sleeve 37, a passive tension adjustment roller 41 is rotatably installed. Through the spring 40 arranged in the telescopic sleeve 37, it can adapt to the tension change generated during the cloth conveying process, thereby adjusting the slight fluctuation of the cloth tension; at the left bottom end of the passive tension adjustment bracket 36, a displacement sensor 43 is arranged. When the displacement sensor 43 detects that the displacement of the passive tension adjustment roller 41 exceeds the preset distance, the active tension adjustment mechanism acts. The electric push rod 35 of the active tension adjustment mechanism drives the movable plate 34 to move up or down until the cloth tension is within the preset range. The active tension adjustment mechanism can adjust the large tension change of the cloth.

[0067] Please refer to Figure 9 , the leveling unit 4 includes a leveling bracket 44. The leveling bracket includes a leveling mechanism and an electrostatic elimination mechanism. The leveling mechanism includes a flattening roller 45 and a driving motor 46 for driving the flattening roller 45 to rotate. The electrostatic elimination mechanism includes an electrostatic elimination roller 47 and a metal wire 48 connected to the electrostatic elimination roller 47. The metal wire 48 is grounded; on the left and right sides of the roller body of the flattening roller 45, symmetrically arranged spiral lines 49 are provided. The spiral lines 49 on the left and right sides have opposite rotation directions; the electrostatic elimination roller 47 is made of metal; a gap for the cloth to pass through is arranged between the electrostatic elimination roller 47 and the flattening roller 45.

[0068] Among them, the electrostatic elimination roller 47 and the flattening roller 45 are arranged opposite to each other. A gap for the cloth to pass through is arranged between them. The gap is slightly smaller than the thickness of the cloth, so that when the cloth passes through the electrostatic elimination roller 47 and the flattening roller 45, it can be fully flattened and the static electricity can be fully eliminated.

[0069] See also Figure 10 The receiving unit 5 includes a receiving bracket, and a receiving roller 9 is rotatably installed on the right side of the receiving roller bracket. The receiving roller 9 is connected to the receiving roller servo motor 10 through a sprocket drive.

[0070] The present invention also includes a cloth winding method using a cloth conveying device, comprising the following steps:

[0071] S1: Place the cloth raw material roll on the unwinding roller 7, pass the cloth end through the first guide roller 24, the second guide roller 25, the third guide roller 26, the fourth guide roller 27, and the fifth guide roller 28 in the deviation correction unit 2 in sequence, pass through the tension adjustment unit 3 and the leveling unit 4, and wind it on the receiving roller 9 of the receiving unit 5, wind it 2-3 times and then fix it;

[0072] S2: Synchronously start the unloading roller servo motor 8 and the receiving roller servo motor 10. When the cloth detection unit detects that the cloth is deflected to the left, the controller 6 controls the first servo motor 18 to rotate, and controls the two first correcting cylinders 12 to move downward, so that the first correcting cylinders 12 are changed from the transmission station to the correcting station. When the cloth detection unit detects that the cloth is back to the original position, the controller 6 controls the two first correcting cylinders 12 to move upward, so that the first correcting cylinders 12 are changed from the correcting station to the transmission station. When the cloth detection unit detects that the cloth is deflected to the right, the controller 6 controls the second servo motor 23 to rotate, and controls the two second correcting cylinders 19 to move downward, so that the second correcting cylinders 19 are changed from the transmission station to the correcting station. When the cloth detection unit detects that the cloth is back to the original position, the controller 6 controls the two second correcting cylinders 19 to move upward, so that the second correcting cylinders 19 are changed from the correcting station to the transmission station.

[0073] S3: In step S2, when the first correcting cylinder 12 or the second correcting cylinder 19 moves from downward to touching the fabric and then continues to move downward to the correcting station, the controller 6 controls the electric push rod 35 to synchronously drive the movable plate 34 to move upward; when the first correcting cylinder 12 or the second correcting cylinder 19 moves upward from the correcting station to being separated from the fabric, the controller 6 controls the electric push rod 35 to synchronously drive the movable plate 34 to move downward;

[0074] S4: When the displacement sensor 43 detects that the position of the tension adjustment roller has changed, the displacement sensor 43 feeds back the position change signal to the controller 6, and the controller 6 converts the position change signal into a fabric tension change signal. The controller 6 controls the action of the electric push rod 35 through the fabric tension change signal, and the electric push rod 35 drives the movable plate 34 to move upward or downward until the fabric tension is in a preset range.

[0075] S5: When step S3 and step S4 are triggered at the same time, step S3 is executed first;

[0076] S6: After the winding of the receiving unit 5 is completed, the finished roll is unloaded and stored in the warehouse.

[0077] Among them, the operation of step S3 enables the tension adjusting unit 3 and the deviation rectifying unit 2 to act in cooperation. Since when the deviation rectifying unit 2 acts, the fabric will be instantaneously tensioned or relaxed, resulting in a large change in the fabric tension. At this time, the tension adjusting unit 3 acts synchronously, that is, synchronously relaxes or tensions the fabric instantaneously, compensating for the tensioning or relaxing amount of the deviation rectifying unit 2 on the fabric, so as to keep the fabric tension stable.

[0078] In step S4, the displacement sensor 43 detects that the position change of the tension adjusting roller has a preset value. When the position change of the tension adjusting roller is less than the preset value, only slight fluctuations occur in the surface fabric tension. At this time, the controller 6 does not issue an action command to the electric push rod 35. When the position change of the tension adjusting roller is greater than the preset value, the controller 6 issues an action command to the electric push rod 35.

[0079] When steps S3 and S4 are triggered simultaneously, the sudden large change in the fabric tension is caused by the structure generated in step S3. Therefore, step S3 is preferentially performed.
