Description

Technical Field

[0001] The invention relates to the technical field of textiles, 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 types of fabrics: 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 needle structure, variable plain needle structure, rib plain needle structure, double rib plain needle structure, jacquard structure, terry structure, etc. Existing textile fabrics are usually processed by automated machinery and equipment, and a winding device is required to reel them up after the textile processing is completed.

[0003] A 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 grooves are symmetrically provided on the frame. The mounting grooves are arranged on the outer side wall of the frame, and a group of mounting grooves are respectively arranged corresponding to a group of placement guide holes, and multiple winding shafts are placed in the placement guide holes; the present application cuts the wound fabric roll and the textile fabric, and then releases a single winding shaft through a rotating rod on a rotating wheel. When the winding shaft enters between a mounting plate and a clamping claw, a group of clamping claws are respectively pulled by the output ends of a group of first hydraulic push rods 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: 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 invention provides a textile fabric winding device and a use method thereof, aiming to solve the problem in the related art that the fabric is prone to wrinkles after cutting, thereby affecting the winding quality.

[0007] The textile fabric winding device of the present invention comprises a supporting mechanism and a cutting mechanism, wherein the supporting mechanism is provided with a tensioning roller, and the tensioning roller is provided with a roller changing mechanism, wherein the roller changing mechanism comprises two roller changing assemblies respectively rotatably connected to two ends of the tensioning roller, and a pressing mechanism is provided between the two roller changing assemblies, and when the roller changing assemblies rotate, the pressing mechanism can be driven to rotate around the tensioning roller; The roll changing assembly includes a rotating ring, a roll changing frame and an arc-shaped guide rail. The guide rail is installed on the rotating ring. The roll changing frame is rotatably connected to the rotating ring. When the rotating ring rotates, the roll changing frame drives the winding roller to rotate to the top of the tensioning roller. The pressing mechanism includes a movable rod, two sliding rods, 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, and 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.

[0008] When it is necessary to replace the winding roller, 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 on the swivel to be horizontal, and then the roller changing frame rotates in the opposite direction and pushes the new winding roller to follow the rotation of 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 to approach the new winding roller, thereby pressing the fabric on the new winding roller to prevent the fabric from being wrinkled on the new winding roller after the cutting mechanism cuts off the fabric.

[0009] Preferably, a fixing rod is installed between the two rotating rings, and mounting grooves are provided at opposite ends of the two rotating rings. A fixing shaft is installed on the inner wall of the mounting groove, and the roller changing frame is rotatably connected to the fixing shaft. A torque spring is provided between the fixing shaft and the roller changing frame.

[0010] 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.

[0011] 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.

[0012] Preferably, the roller changing mechanism further comprises a transmission assembly for driving the rotating ring to rotate, and the transmission assembly is arranged on one of the rotating rings.

[0013] Preferably, the transmission assembly includes gear one, gear two, a rotating rod and an avoidance groove, gear one is installed at one end of the swivel, the avoidance groove is opened on gear one, the reset rod passes through the avoidance groove and extends to the outside of the avoidance groove, gear two is meshed with gear one, the rotating rod is installed at one end of gear two, and the rotating rod is rotatably connected to one side of the inner wall of the support mechanism.

[0014] The rotation of the rotating rod can drive the second gear to rotate, and the second gear can drive the rotating ring at the end of the tensioning roller to rotate through the first gear, so as to drive the movable rod to rotate.

[0015] Preferably, the support mechanism comprises a guide assembly, a material removal assembly and two support assemblies, the guide assembly is arranged on one side inside the two support assemblies, and the material removal assembly is arranged on the other side inside the two support assemblies.

[0016] Preferably, the support assembly includes a support box, a rotating rod and a support frame, the tensioning roller is rotatably connected between two support boxes, the rotating rod is rotatably connected to one side of the support box, and the support frame is mounted on the rotating rod.

[0017] Preferably, a limiting rod is installed on one side of the support box, and the limiting rod can contact the roller changing frame to receive the roller changing frame into the installation groove.

[0018] 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 groove. When the roller changing frame is retracted into the installation groove, the movable rod lifts the fabric. As the swivel continues to rotate, the roller changing frame passes over the limit rod. At this time, the roller changing frame is reset and pushes the new winding roller to move.

[0019] Preferably, a limiting plate is installed on one side of the support box close to the limiting rod, and the limiting plate can contact the reset rod to drive the sliding rod to reset.

[0020] During the rotation of the swivel, the limit plate can drive the reset rod to reset, thereby driving the slide rod to reset.

[0021] A method for using a textile fabric winding device, using the textile fabric winding device, comprises the following steps: 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 on the outside of the tensioning roller and lift the fabric from the tensioning roller, and 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 on the new winding roller; S2: Cut the fabric by cutting knife; 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.

[0022] The effect is that when replacing the winding roller, the rotating rod drives the swivel to rotate at the end of the tensioning roller through gear 1 on gear 2, and at the same time, the fixed rod, the roller changing frame and the movable rod follow the swivel to rotate synchronously. In the process of the fixed rod and the movable rod following the rotation of the swivel, the fixed rod and the movable rod successively lift 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 on the swivel to be horizontal, and then the roller changing frame rotates in the opposite direction and pushes the new winding roller to follow the rotation of 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 to approach the new winding roller, thereby pressing the fabric on the new winding roller to prevent the fabric from being wrinkled on the new winding roller after the cutting mechanism cuts off the fabric.

[0023] The above technical scheme is adopted, and the beneficial effects of the present invention are as follows: when it is necessary to replace the winding roller, the swivel is rotated at the end of the tensioning roller, and the roller changing frame and the movable rod follow the swivel to rotate synchronously. 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 on the swivel to be horizontal, and then the roller changing frame rotates in the opposite direction and pushes the new winding roller to follow the rotation of 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 to approach the new winding roller, thereby pressing the fabric on the new winding roller to prevent the fabric from being wrinkled on the new winding roller after the cutting mechanism cuts off the fabric, thereby avoiding affecting the winding of the fabric, thereby improving the winding quality of the fabric.

DETAILED DESCRIPTION

[0033] 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.

[0034] like Figures 1 to 8 As shown, the textile fabric winding device of the present invention comprises a supporting mechanism 10, a cutting mechanism 20, a roller changing mechanism 30 and a pressing mechanism 40. The cutting mechanism 20 is installed on the top of the supporting mechanism 10 to cut the fabric, the roller changing mechanism 30 is arranged inside the supporting mechanism 10, and the pressing mechanism 40 is arranged on the roller changing mechanism 30.

[0035] When replacing the winding roller, the roller changing mechanism 30 rotates in the supporting mechanism 10 to drive the pressing mechanism 40 to lift up 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 makes the fabric close to the new winding roller. Then the cutting mechanism 20 cuts off 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.

[0036] like Figure 1 to Figure 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 inside of the two support assemblies 11, and the blanking assembly 13 is rotatably connected to the other side of the inside of the two support assemblies 11.

[0037] 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 step 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 at the top of the boss to guide the winding roller to move to the unloading assembly 13 after the winding is completed. A motor for driving the rotating rod 112 to rotate is installed inside the support box 111.

[0038] 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 to allow the winding roller to continue 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.

[0039] 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 .

[0040] 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 up and down. Both guide rollers 121 are rotatably connected between the two support boxes 111, and the upper guide roller 121 is arranged near the edge top of the support box 111. The reversing roller 122 and the rotating roller 123 are spaced apart up and down, and the rotating roller 123 is rotatably connected to the bottom of one side of the support box 111. A motor for driving the rotating roller 123 to rotate is installed inside the support box 111, and the reversing roller 122 is rotatably connected to the support box 111 and is arranged near the guide roller 121 located below.

[0041] There are two pulleys 124, which are respectively mounted on the outer sides of the two ends of the rotating roller 123. The tensioning roller 125 is rotatably connected to one side of the supporting box 111 and is arranged close to the supporting frame 113. There are two pulleys 126, which are respectively mounted on the outer sides of the two ends of the tensioning roller 125. The pulley 124 is connected to the pulley 126 through a belt.

[0042] 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.

[0043] 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, and a motor for driving the connecting shaft 131 to rotate is installed inside the support box 111. There are two guide frames 132 and two grooves 133, and the two grooves 133 are respectively opened on the top of one side of the two guide frames 132, and the two guide frames 132 are respectively installed on the outer sides of both ends of the connecting shaft 131.

[0044] 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.

[0045] like Figure 1 and Figure 3 to Figure 4As shown, the cutting mechanism 20 includes an electric slide rail 21, an electric slider 22, a connecting frame 23, a driving member 24 and a cutting knife 25. The electric slide rail 21 is installed on one side of the top of the support box 111 through a gantry, the electric slider 22 is slidably connected to the electric slide rail 21, and the connecting frame 23 is installed at the bottom of one side of the electric slider 22, and the shape of the connecting frame 23 is U-shaped. The driving member 24 is installed on one side of the connecting frame 23. In this embodiment, the driving member 24 is a motor. The cutting knife 25 is located inside the connecting frame 23, and a slot for the cutting knife 25 to extend is opened on the connecting frame 23. The driving shaft of the driving member 24 is installed at one end of the cutting knife 25.

[0046] 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.

[0047] 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. There are two roller changing assemblies 31, and the two roller changing assemblies 31 are respectively sleeved on the outer sides of the two ends of the tensioning roller 125. The transmission assembly 32 is arranged on one side of one of the roller changing assemblies 31, and the fixing rod 33 is installed between the two roller changing assemblies 31. The 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 located on one side of the tensioning roller 125 and below the fabric.

[0048] 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 groove 316. The guide rail 312 is in an arc shape, and the end of the guide rail 312 is installed on the outside of the rotating ring 311. The rotating rings 311 on the two roller changing assemblies 31 are provided with a mounting groove 313 at the opposite ends, the fixed shaft 314 is installed on the inner wall of the mounting groove 313, the roller changing frame 315 is rotatably connected to the outside of the fixed shaft 314, and a torque spring (not shown in the figure) is provided between the fixed shaft 314 and the roller changing frame 315. The other end of the rotating ring 311 is provided with a guide groove 316, which is in an arc shape and is arranged cocentrically with the guide rail 312.

[0049] like Figure 3 and Figures 5 and 6As shown, the transmission assembly 32 includes a gear 1 321, a gear 2 322, a rotating rod 323 and an avoidance groove 324. The gear 1 321 is mounted on one end of the rotating ring 311 and sleeved on the tensioning roller 125, and the gear 2 322 is meshedly connected to one side of the gear 1 321. One end of the rotating rod 323 is mounted on one end of the 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 for driving the rotating rod 323 to rotate is installed inside the support box 111. The gear 1 321 is provided with an avoidance groove 324 corresponding to the guide groove 316.

[0050] When the rotating rod 323 rotates, the rotating rod 323 can drive 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 on the outer side of the tensioning roller 125, and the fixed rod 33 and the pressing mechanism 40 gradually lift the fabric from the tensioning roller 125 during the rotation process. When the roller changing frame 315 rotates, it contacts the limit rod 114, so that the roller changing frame 315 rotates in the installation groove 313, and the torque spring accumulates force. When the roller changing frame 315 completely enters the installation groove 313, driven by the swivel 311, the roller changing frame 315 can 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 the new winding roller is in contact with the fabric.

[0051] 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 two ends of the movable rod 41 are respectively slidably connected to the guide rails 312 of the two roller changing assemblies 31, and the number of the reset member and the elastic member are both two. The two reset members are respectively arranged at the outer sides of the two ends of the movable rod 41, and the two elastic members are both arranged on the movable rod 41. The movable rod 41 is provided with a slide groove 45 for accommodating the elastic member.

[0052] 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 in an arc shape, and the slide bar 42 is located inside the guide rail 312. One end of the slide bar 42 is mounted on the outside of one end of the movable rod 41, and the other end of the slide bar 42 extends into the rotating ring 311. The slide bar 42 is made of iron material, and an electromagnet (not shown in the figure) for adsorbing the slide bar 42 is installed inside the rotating ring 311. The spring 43 is sleeved on the outside of one end of the slide bar 42, one end of the spring 43 is mounted on the outer wall of the movable rod 41, and the other end of the spring 43 is mounted on the inner wall of the guide rail 312 to push the movable rod 41 to move. One end of the reset bar 44 is mounted on the outside of the other end of the slide bar 42, and 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, and the reset bar 44 can contact the limit plate 115.

[0053] Continue to refer Figures 5 to 8 As shown, the elastic member includes a slide frame 46, a spring 47, and a roller 48. The slide frame 46 is T-shaped, and is slidably connected in the slide slot 45. One end of the slide frame 46 passes through the movable rod 41 and extends to the outside of the movable rod 41. The roller 48 is rotatably connected to one end of the slide frame 46. There are two springs 47, which are respectively located on both sides of the slide frame 46. One end of the spring 47 is installed on the movable rod 41, and the other end of the spring 47 is installed on the slide frame 46.

[0054] When the roller changing frame 315 pushes the new winding roller to the top of the tensioning roller 125, under the action of the spring 2 47, the slide frame 46 drives the roller 48 to press the fabric onto the new winding roller. At this time, the fabric is cut off by the cutting knife 25, and the cut fabric is still pressed onto the new winding roller under the action of the roller 48 to prevent the fabric from wrinkling on the new winding roller. After the fabric is cut off, the electromagnet in the rotating ring 311 is powered off. At this time, under the action of the spring 1 43, the slide bar 42 is pushed 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, preventing the end of the fabric from wrinkling during the subsequent winding process, thereby further ensuring the winding quality.

[0055] Working principle: When the winding roller needs to be replaced, the rotating rod 323 drives the rotating ring 311 to rotate through the gear 1 321 on the gear 2 322. At this time, the rotating ring 311 drives the roller changing frame 315, the fixed rod 33 and the movable rod 41 to rotate synchronously on the outside of the tensioning roller 125. The fixed rod 33 and the movable rod 41 gradually lift the fabric from the tensioning roller 125 during the rotation process. The roller changing frame 315 contacts the limiting rod 114 when rotating, so that the roller changing frame 315 rotates in the installation groove 313, and the torque spring accumulates force. When the roller changing frame 315 completely enters the installation groove 313, driven by the rotating ring 311, the roller changing frame 315 can pass over the limiting 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. At this time, the new winding roller is located between the inner side of the guide rail 312 and the roller changing frame 315.

[0056] At the same time, under the action of spring 2 47, the slide frame 46 drives the roller 48 to press the fabric onto the new winding roller, and at this time, the fabric is cut off by the cutting knife 25. When the fabric is cut off, the electromagnet in the rotating ring 311 is powered off, and at this time, the slide bar 42 is pushed to slide in the guide rail 312 under the action of spring 1 43, and 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.

[0057] When the fabric is covered on the new winding roller, the rotating rod 112 drives the support frame 113 to rotate, releases the limit of the winding roller after winding is completed, and moves the winding roller after winding to the guide frame 132, and then the support frame 113 is reset.

[0058] The rotating ring 311 is driven to rotate by the gear 1 321. 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. As the rotating ring 311 continues to rotate, the roller changing frame 315 enters the installation groove 313 again under the action of the new winding roller, so that the roller changing frame 315 passes over the new winding roller, and the replacement of the winding roller is completed. Then the rotating ring 311 continues to rotate until it is reset. During the reset process of the rotating ring 311, 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 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 rotating ring 311 adsorbs the slide rod 42 again.

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 to drive the slide bar 42 to reset. After the slide bar 42 is reset, the reset rod 44 passes over the limit plate 115, and the electromagnet in the swivel 311 absorbs the slide bar 42 again.
