Description

Technical Field

[0001] The present invention relates to the field of textile technology, and in particular to a textile fabric winding device and a use method thereof. Background Art

[0002] Textile fabrics are fabrics woven using different weaving methods. According to the weaving method, there are two categories: weft knitted fabrics and warp knitted fabrics. Weft knitted fabrics are often made of low-elastic polyester yarn or special-shaped polyester yarn, nylon yarn, cotton yarn, wool yarn, etc., and are woven on various weft knitting machines using plain stitch, variable plain stitch, rib plain stitch, double rib plain stitch, jacquard stitch, terry stitch, etc. Existing textile fabrics are usually processed by automated machinery and equipment, and a winding device is required for winding after the textile processing is completed.

[0003] The Chinese patent document with authorization announcement number CN118850839B discloses a winding device for textile fabric processing, which includes a frame, a group of automatic shaft loading mechanisms, a winding mechanism and a roll changing mechanism. A group of placement guide holes are symmetrically opened on the frame, and a group of mounting slots are symmetrically provided on the frame. The mounting slots are arranged on the outer wall of the frame, and a group of mounting slots are respectively arranged corresponding to a group of placement guide holes, and multiple winding shafts are placed in the placement guide holes; this application cuts the wound fabric roll and the textile fabric, and then releases a single winding shaft through the rotating rod on the rotating wheel. When the winding shaft enters between the mounting plate and the clamping claw, the output end of a group of first hydraulic push rods pulls a group of clamping claws to clamp the two ends of the winding shaft. At this time, the side walls of the winding shaft clamped at both ends are tightly attached to the rotating drum, and the winding shaft is automatically docked into the groove of the first mounting frame by driving the output end of the third motor.

[0004] However, the structural design of the above-mentioned related technology is as follows: during the winding process of the textile fabric, although it can be wound uninterruptedly, the fabric needs to be cut during the roller changing process. The textile fabric is relatively soft. When the tensioned fabric is cut, the fabric will lose its tension and become loose instantly, causing wrinkles on the new winding roller, which in turn leads to poor quality of subsequent fabric winding.

[0005] Therefore, a textile fabric winding device and a method of using the same are proposed to solve the above-mentioned problems. Summary of the Invention

[0006] The present invention provides a textile fabric winding device and a method for using the same, aiming to solve the problem in the related art that the fabric is prone to wrinkles after being cut, thereby affecting the winding quality.

[0007] The textile fabric winding device of the present invention includes a support mechanism and a cutting mechanism. The support mechanism is provided with a tensioning roller, and the tensioning roller is provided with a roller changing mechanism. The roller changing mechanism includes two roller changing assemblies that are respectively rotatably connected to the two ends of the tensioning roller. A pressing mechanism is provided between the two roller changing assemblies. When the roller changing assembly rotates, it can drive the pressing mechanism to rotate around the tensioning roller.

[0008] The roller changing assembly includes a swivel, a roller changing frame and an arc-shaped guide rail. The guide rail is installed on the swivel, and the roller changing frame is rotatably connected to the swivel. When the swivel rotates, the roller changing frame drives the winding roller to rotate to the top of the tensioning roller.

[0009] The pressing mechanism includes a movable rod, two sliding rods and two sliding frames and a roller rotatably connected to the sliding frame. The sliding rod is elastically slidably connected to the guide rail along the trajectory of the guide rail. The movable rod is installed on the two sliding rods. The sliding frame is elastically slidably connected to the movable rod along the radial direction of the movable rod. When the winding roller rotates to the top of the tensioning roller, the roller presses the fabric onto the winding roller.

[0010] When the winding roller needs to be replaced, the swivel is rotated at the end of the tensioning roller, and the roller changing frame and the movable rod rotate synchronously with the swivel. In the process of the movable rod following the rotation of the swivel, the movable rod lifts the fabric from the bottom of the fabric, and in the process of the roller changing frame following the rotation of the swivel, the roller changing frame first rotates to a horizontal position on the swivel, and then the roller changing frame rotates in the opposite direction and pushes the new winding roller to rotate with the swivel, so that the new winding roller can be pushed to the top of the tensioning roller and located on the top of the fabric. At this time, the new winding roller is located between the guide rail and the roller changing frame. When the new winding roller moves to the top of the tensioning roller and is located above the fabric, the sliding frame drives the roller close to the new winding roller, thereby pressing the fabric on the new winding roller to prevent the fabric from wrinkling on the new winding roller after the cutting mechanism cuts off the fabric.

[0011] Preferably, a fixing rod is installed between the two rotating rings, and a mounting groove is opened at the opposite end of the two rotating rings. A fixed shaft is installed on the inner wall of the mounting groove, and the roller changing frame is rotatably connected to the fixed shaft. A torque spring is provided between the fixed shaft and the roller changing frame.

[0012] When the rotating ring rotates, it can drive the fixed rod to rotate. At this time, the fixed rod and the movable rod successively lift the fabric.

[0013] Preferably, the end of the slide rod extends to the inside of the rotating ring, a reset rod is installed on the end of the slide rod, and a guide groove for the reset rod to slide is provided on the rotating ring.

[0014] Preferably, the roller changing mechanism further includes a transmission assembly for driving the rotating ring to rotate, and the transmission assembly is arranged on one of the rotating rings.

[0015] Preferably, the transmission assembly includes gear 1, gear 2, a rotating rod and an avoidance groove, gear 1 is installed at one end of the rotating ring, the avoidance groove is opened on gear 1, the reset rod passes through the avoidance groove and extends to the outside of the avoidance groove, gear 2 is engaged with gear 1, the rotating rod is installed at one end of gear 2, and the rotating rod is rotatably connected to one side of the inner wall of the support mechanism.

[0016] The rotation of the rotating rod can drive the second gear to rotate, and the second gear can drive the rotating ring to rotate at the end of the tensioning roller through the first gear, so as to drive the movable rod to rotate.

[0017] Preferably, the support mechanism includes a guide assembly, a blanking assembly and two support assemblies, the guide assembly is arranged on one side inside the two support assemblies, and the blanking assembly is arranged on the other side inside the two support assemblies.

[0018] Preferably, the support assembly includes a support box, a rotating rod and a support frame, the tensioning roller is rotatably connected between the two support boxes, the rotating rod is rotatably connected to one side of the support box, and the support frame is installed on the rotating rod.

[0019] Preferably, a limiting rod is installed on one side of the support box, and the limiting rod can contact the roller changing frame to store the roller changing frame into the installation groove.

[0020] The limit rod can be used to block the roller changing frame when replacing a new winding roller, so that the roller changing frame can rotate in the installation slot. When the roller changing frame is retracted into the installation slot, the movable rod lifts the fabric. As the swivel continues to rotate, the roller changing frame passes the limit rod. At this time, the roller changing frame is reset and pushes the new winding roller to move.

[0021] Preferably, a limiting plate is installed on one side of the support box close to the side of the limiting rod, and the limiting plate can contact the reset rod to drive the sliding rod to reset.

[0022] During the rotation of the swivel, the limit plate can drive the reset rod to reset, thereby driving the sliding rod to reset.

[0023] A method for using a textile fabric winding device, using the textile fabric winding device, comprises the following steps:

[0024] S1: The rotating rod drives the rotating ring to rotate through the gear 1 on the gear 2, and the rotating ring drives the roller changing frame, the fixed rod and the movable rod to rotate outside the tensioning roller and lift the fabric from the tensioning roller. The roller changing frame pushes the new winding roller to the top of the tensioning roller, so that the new winding roller is located between the inner side of the guide rail and the roller changing frame, and at the same time, the roller presses the fabric onto the new winding roller.

[0025] S2: Cut the fabric with a cutting knife;

[0026] S3: The slide bar slides in the guide rail, and at the same time, the slide bar drives the roller on the slide frame to rotate around the new winding roller through the movable rod, so that the end of the fabric is covered on the new winding roller.

[0027] When the new winding roller moves to the top of the tensioning roller and is located above the fabric, the sliding frame drives the roller to approach the new winding roller, thereby pressing the fabric on the new winding roller to prevent the fabric from wrinkling on the new winding roller after the cutting mechanism cuts the fabric.

[0028] When the new winding roller moves to the top of the tensioning roller and is located above the fabric, the sliding frame drives the roller to approach the new winding roller, thereby pressing the fabric on the new winding roller to prevent the fabric from wrinkling on the new winding roller after the cutting mechanism cuts the fabric, thereby avoiding affecting the winding of the fabric, thereby improving the winding quality of the fabric.

[0042] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0043] like Figures 1 to 8 As shown, the textile fabric winding device of the present invention includes a support mechanism 10, a cutting mechanism 20, a roller changing mechanism 30, and a pressing mechanism 40. The cutting mechanism 20 is mounted on top of the support mechanism 10 to cut the fabric, the roller changing mechanism 30 is disposed inside the support mechanism 10, and the pressing mechanism 40 is disposed on the roller changing mechanism 30.

[0044] When replacing the winding roller, the roller changing mechanism 30 rotates in the supporting mechanism 10 to drive the pressing mechanism 40 to lift the fabric that is not wound on the new winding roller. At the same time, the roller changing mechanism 30 also drives the new winding roller to rotate around the roller changing mechanism 30 and make the fabric close to the new winding roller. Then the cutting mechanism 20 cuts the fabric. At this time, the fabric is pressed against the new winding roller by the pressing pressure of the pressing mechanism 40 to prevent the fabric from loosening due to loss of tension.

[0045] like Figures 1 to 2 As shown, the support mechanism 10 includes a support assembly 11, a guide assembly 12 and a blanking assembly 13. There are two support assemblies 11, the guide assembly 12 is rotatably connected to one side of the interior of the two support assemblies 11, and the blanking assembly 13 is rotatably connected to the other side of the interior of the two support assemblies 11.

[0046] like Figures 2 to 3 As shown, the support assembly 11 includes a support box 111, a rotating rod 112 and a support frame 113. The support box 111 is stepped, and the top of the support box 111 has three stepped surfaces. In the initial state, the new winding roller is located on the second step surface of the support box 111, and the winding roller being wound is located on the third step surface of the support box 111. The rotating rod 112 is rotatably connected to one side of the support box 111, and the support frame 113 is installed on the rotating rod 112. A boss with an inclined surface is provided on the third step surface of the support box 111, and the end of the winding roller being wound is located on the top of the boss to guide the winding roller to move to the unloading assembly 13 after winding is completed. A motor for driving the rotating rod 112 to rotate is installed inside the support box 111.

[0047] The support frame 113 can prevent the replaced winding roller from continuing to move, and then the winding roller is driven to rotate by an external driver so that the winding roller continues to reel in the fabric. When the winding roller has finished reeling, the motor drives the support frame 113 to rotate through the rotating rod 112 to release the limit of the winding roller. At this time, the winding roller moves along the inclined surface of the boss of the support box 111 to the unloading assembly 13.

[0048] like Figure 3 As shown, a limiting rod 114 is installed on a side of the support box 111 away from the rotating rod 112 , and a limiting plate 115 is installed on a side of the support box 111 close to the limiting rod 114 .

[0049] like Figures 2 to 3As shown, the guide assembly 12 includes a guide roller 121, a reversing roller 122, a rotating roller 123, a pulley 124, a tensioning roller 125, and a pulley 2 126. There are two guide rollers 121, which are staggered vertically. Both guide rollers 121 are rotatably connected between the two support boxes 111, with the upper guide roller 121 positioned near the top edge of the support box 111. The reversing roller 122 and the rotating roller 123 are spaced apart vertically. The rotating roller 123 is rotatably connected to the bottom side of the support box 111. A motor for driving the rotating roller 123 is installed within the support box 111. The reversing roller 122 is rotatably connected to the support box 111 and positioned near the lower guide roller 121.

[0050] There are two pulleys 124, each mounted on the outer sides of the rotating roller 123. A tensioning roller 125 is rotatably connected to one side of the support box 111 and is disposed near the support frame 113. There are two pulleys 126, each mounted on the outer sides of the tensioning roller 125. The pulleys 124 are connected to the pulleys 126 via a belt.

[0051] When the rotating roller 123 rotates, the rotating roller 123 drives the second pulley 126 to rotate through the first pulley 124, and the second pulley 126 drives the tensioning roller 125 to rotate.

[0052] Continue to refer Figures 2 to 3 As shown, the blanking assembly 13 includes a connecting shaft 131, a guide frame 132, and a groove 133. The connecting shaft 131 is rotatably connected to the bottom of one side of the two support boxes 111. A motor is installed inside the support boxes 111 to drive the connecting shaft 131. There are two guide frames 132 and two grooves 133, each with two grooves 133 located on the top of one side of each guide frame 132. The two guide frames 132 are mounted on the outer sides of the connecting shaft 131.

[0053] When the winding roller moves along the inclined surface of the boss of the support box 111 after winding is completed, the end of the winding roller enters the groove 133 of the guide frame 132. At this time, the connecting shaft 131 drives the winding roller on the guide frame 132 to rotate around the connecting shaft 131 to move the winding roller out of the support box 111 after winding is completed.

[0054] like Figure 1 and Figures 3 and 4As shown, the cutting mechanism 20 includes an electric rail 21, an electric slider 22, a connecting frame 23, a driver 24, and a cutting blade 25. The electric rail 21 is mounted on one side of the top of the support box 111 via a gantry. The electric slider 22 is slidably connected to the electric rail 21. The connecting frame 23 is mounted on the bottom of one side of the electric slider 22 and has a U-shaped shape. The driver 24 is mounted on one side of the connecting frame 23. In this embodiment, the driver 24 is a motor. The cutting blade 25 is located within the connecting frame 23. The connecting frame 23 has a slot for the cutting blade 25 to extend. The drive shaft of the driver 24 is mounted on one end of the cutting blade 25.

[0055] When the fabric needs to be cut, the electric slide rail 21 drives the electric slider 22 to move along its length direction. At the same time, the electric slider 22 drives the cutting knife 25 to move through the connecting frame 23. The cutting knife 25 can cut the fabric during the movement so that the fabric can be covered on the new winding roller.

[0056] like Figures 1 to 3 As shown, the roller-changing mechanism 30 includes a roller-changing assembly 31, a transmission assembly 32, and a fixing rod 33. Two roller-changing assemblies 31 are provided, each positioned outside the tensioning roller 125. The transmission assembly 32 is positioned on one side of one roller-changing assembly 31, and the fixing rod 33 is mounted between the two roller-changing assemblies 31. A pressing mechanism 40 is slidably connected between the two roller-changing assemblies 31. In the initial position, the pressing mechanism 40 and the fixing rod 33 are both positioned on one side of the tensioning roller 125 and below the fabric.

[0057] like Figure 3 and Figures 5 to 7 As shown, the roller changing assembly 31 includes a rotating ring 311, a guide rail 312, a fixed shaft 314, a roller changing frame 315, and a guide slot 316. The guide rail 312 is arcuate, with its end mounted on the outside of the rotating ring 311. Mounting slots 313 are defined on opposite ends of the rotating rings 311 of both roller changing assemblies 31. The fixed shaft 314 is mounted on the inner wall of the mounting slot 313. The roller changing frame 315 is rotatably connected to the outside of the fixed shaft 314. A torque spring (not shown) is provided between the fixed shaft 314 and the roller changing frame 315. A guide slot 316 is defined on the other end of the rotating ring 311. This arcuate guide slot 316 is coaxial with the guide rail 312.

[0058] like Figure 3 and Figures 5 and 6As shown, the transmission assembly 32 includes gear 1 321, gear 2 322, a rotating rod 323, and an escape groove 324. Gear 1 321 is mounted on one end of the rotating ring 311 and is positioned over the tensioning roller 125. Gear 2 322 is meshed with one side of gear 1 321. One end of the rotating rod 323 is mounted on one end of gear 2 322, and the other end of the rotating rod 323 is rotatably connected to one side of the support box 111. A motor is installed within the support box 111 to drive the rotating rod 323. An escape groove 324 is defined on gear 1 321, corresponding to the guide groove 316.

[0059] When the rotating rod 323 rotates, the rotating rod 323 drives the rotating ring 311 to rotate on the tensioning roller 125 through the gear 1 321 on the gear 2 322. When the rotating ring 311 rotates, the rotating ring 311 drives the roller changing frame 315, the fixed rod 33 and the pressing mechanism 40 to rotate synchronously outside the tensioning roller 125. During the rotation process, the fixed rod 33 and the pressing mechanism 40 gradually lift the fabric from the tensioning roller 125. When the roller changing frame 315 rotates, it contacts the limit rod 114, causing the roller changing frame 315 to rotate in the installation groove 313. At the same time, the torque spring accumulates force. When the roller changing frame 315 completely enters the installation groove 313, the roller changing frame 315 is driven by the rotating ring 311 to pass over the limit rod 114. At this time, the roller changing frame 315 is reset and pushes the new winding roller to the top of the tensioning roller 125, so that the new winding roller is located between the inner side of the guide rail 312 and the roller changing frame 315, and at the same time, the new winding roller is in contact with the fabric.

[0060] like Figure 2 、 Figure 3 、 Figure 5 and Figure 7 As shown, the pressing mechanism 40 includes a movable rod 41, a reset member, and an elastic member. The ends of the movable rod 41 are slidably connected to the guide rails 312 of the two roller changing assemblies 31. There are two reset members and two elastic members, each of which is disposed on the outer sides of the movable rod 41. The two elastic members are both disposed on the movable rod 41, and the movable rod 41 is provided with a slide groove 45 for accommodating the elastic member.

[0061] like Figures 5 to 8As shown, the reset member includes a slide bar 42, a spring 43, and a reset bar 44. The slide bar 42 is arc-shaped and is located inside the guide rail 312. One end of the slide bar 42 is mounted outside one end of the movable bar 41, and the other end of the slide bar 42 extends into the rotating ring 311. The slide bar 42 is made of iron, and an electromagnet (not shown) is installed inside the rotating ring 311 to attract the slide bar 42. The spring 43 is sleeved outside one end of the slide bar 42. One end of the spring 43 is mounted on the outer wall of the movable bar 41, and the other end of the spring 43 is mounted on the inner wall of the guide rail 312 to push the movable bar 41 to move. One end of the reset bar 44 is mounted outside the other end of the slide bar 42. The other end of the reset bar 44 passes through the guide groove 316 and the avoidance groove 324 in sequence and extends to the outside of the avoidance groove 324. The reset bar 44 can contact the limit plate 115.

[0062] Continue to refer Figures 5 to 8 As shown, the elastic member includes a slide 46, a second spring 47, and a roller 48. The slide 46 is T-shaped and slidably connected to the slide slot 45. One end of the slide 46 extends through the movable rod 41 and outwardly of the movable rod 41. The roller 48 is rotatably connected to one end of the slide 46. There are two second springs 47, one located on either side of the slide 46. One end of the second spring 47 is mounted on the movable rod 41, and the other end of the second spring 47 is mounted on the slide 46.

[0063] When the roller-changing frame 315 pushes the new winding roller to the top of the tensioning roller 125, the slide frame 46, under the action of spring 2 47, drives the roller 48 to press the fabric onto the new winding roller. At this point, the fabric is cut by the cutting blade 25, and the cut fabric is still pressed against the new winding roller by the action of roller 48, preventing the fabric from wrinkling on the new winding roller. After the fabric is cut, the electromagnet in the rotating ring 311 is de-energized. At this time, the spring 1 43 drives the slide bar 42 to slide within the guide rail 312. Simultaneously, the slide bar 42 drives the roller 48 on the slide frame 46 to rotate around the new winding roller via the movable rod 41, so that the end of the fabric covers the new winding roller, preventing wrinkles during the subsequent winding process, thereby further ensuring winding quality.

[0064] Working Principle: When the winding roller needs to be replaced, the rotating rod 323 drives the rotating ring 311 via gear 1 321 on gear 2 322. The rotating ring 311 then drives the roller-changing frame 315, the fixed rod 33, and the movable rod 41 to rotate synchronously outside the tensioning roller 125. As the fixed rod 33 and the movable rod 41 rotate, they gradually lift the fabric from the tensioning roller 125. As the roller-changing frame 315 rotates, it contacts the limiting rod 114, causing it to rotate within the mounting slot 313. Simultaneously, the torque spring accumulates force. When the roller-changing frame 315 fully enters the mounting slot 313, driven by the rotating ring 311, it passes over the limiting rod 114. The roller-changing frame 315 then resets and pushes the new winding roller to the top of the tensioning roller 125. The new winding roller is now positioned between the inner side of the guide rail 312 and the roller-changing frame 315.

[0065] At the same time, under the action of spring 2 47, the slide 46 drives the roller 48 to press the fabric onto the new take-up roller, at which point the fabric is cut by the cutter 25. After the fabric is cut, the electromagnet in the rotating ring 311 is de-energized, and the spring 1 43 drives the slide 42 to slide within the guide rail 312. Simultaneously, the slide 42 drives the roller 48 on the slide 46 via the movable rod 41 to rotate around the new take-up roller, thereby wrapping the end of the fabric over the new take-up roller.

[0066] When the fabric is covered on the new winding roller, the rotating rod 112 drives the support frame 113 to rotate, releasing the limit of the winding roller after winding is completed, so that the winding roller after winding is completed moves to the guide frame 132, and then the support frame 113 is reset.

[0067] Gear 1 321 continues to drive the swivel 311 to rotate. At this time, the swivel 311 drives the new winding roller to the boss of the support box 111 via the guide rail 312 and the roller changing frame 315 to continue winding the fabric. As the swivel 311 continues to rotate, the roller changing frame 315, under the action of the new winding roller, re-enters the installation slot 313, allowing the roller changing frame 315 to pass over the new winding roller, completing the replacement of the winding roller. The swivel 311 then continues to rotate until it resets. During the reset process, the reset rod 44 contacts the limit plate 115. At this time, under the action of the limit plate 115, the limit plate 115 pushes the reset rod 44 to slide in the guide slot 316, thereby driving the slide rod 42 to reset. After the slide rod 42 resets, the reset rod 44 passes the limit plate 115, and the electromagnet in the swivel 311 once again attracts the slide rod 42.

[0068] A method for using a textile fabric winding device, using the textile fabric winding device, comprises the following steps:

[0069] S1: The rotating rod 323 drives the rotating ring 311 to rotate through the gear 1 321 on the gear 2 322. The rotating ring 311 drives the roller changing frame 315, the fixed rod 33 and the movable rod 41 to rotate outside the tensioning roller 125 and lift the fabric from the tensioning roller 125. The roller changing frame 315 pushes the new winding roller to the top of the tensioning roller 125, so that the new winding roller is located between the inner side of the guide rail 312 and the roller changing frame 315. At the same time, the roller 48 presses the fabric onto the new winding roller.

[0070] S2: Cut the fabric by cutting knife 25;

[0071] S3: At the same time, the electromagnet in the rotating ring 311 is de-energized, causing the slide bar 42 to slide in the guide rail 312. At the same time, the slide bar 42 drives the roller 48 on the slide frame 46 to rotate around the new winding roller through the movable rod 41, so that the end of the fabric is covered on the new winding roller;

[0072] S4: The rotating rod 112 drives the support frame 113 to rotate, releasing the limit of the winding roller after winding is completed, so that the winding roller moves to the guide frame 132 after winding is completed;

[0073] S5: The rotating ring 311 continues to rotate. At this time, the rotating ring 311 drives the new winding roller to move to the boss of the support box 111 through the guide rail 312 and the roller changing frame 315 to continue to wind the fabric;

[0074] S6: The swivel 311 continues to rotate and reset. During the resetting process of the swivel 311, the reset rod 44 contacts the limit plate 115. Under the action of the limit plate 115, the limit plate 115 pushes the reset rod 44 to slide in the guide groove 316, thereby driving the slide rod 42 to reset. After the slide rod 42 is reset, the reset rod 44 passes over the limit plate 115, and the electromagnet in the swivel 311 attracts the slide rod 42 again.
