Description

Technical Field

[0001] This invention relates to the field of fabric winding technology, specifically to a fabric winding device and method for knitting machines used in the production of knitted fabrics. Background Technology

[0002] In the textile operation process, after the knitting machine finishes weaving the fabric, one end of the fabric needs to be pulled to the fabric winding machine. The fabric winding machine is used to roll the fabric onto a roll of fabric for easy transportation and storage. The fabric is stored by winding the fabric.

[0003] During the winding process of a fabric roll, the fabric path needs to be arranged. Then, one end of the fabric is connected to the roll, and the fabric is wound up by rotating the roll. After winding, the fabric needs to be cut, and then the roll can be replaced. Generally, the fabric is cut by sliding a cutter on the surface of the fabric. After cutting, the wound fabric is removed, and a new roll is installed in the winding equipment. Then, one end of the fabric is wrapped around the outside of the new roll, and the fabric is wound up again by rotating the roll. During the cutting process, the cutter will generate shearing force on the fabric. At this time, the two sides of the cut will pull the wound fabric. At the same time, because the fabric is not taut, it will bend or wrinkle under the force during the cutting process. This will cause the cut surface of the fabric to be tilted, thus affecting the subsequent winding of the fabric. Summary of the Invention

[0008] As a further embodiment of the present invention: the first rotating shaft, the third rotating shaft, and the second rotating shaft are at the same horizontal height, and the second rotating shaft is also provided with a driven gear. The third rotating shaft is connected to the first rotating shaft and the second rotating shaft through a driving gear and a driven gear.

[0010] As a further embodiment of the present invention, the driven gear and the driving gear have the same diameter.

[0011] As a further embodiment of the present invention: the straightening connector includes a telescopic cylinder installed at the bottom of the second connecting frame, the output end of the telescopic cylinder is connected to a limiting plate, a connecting cylinder is sleeved on the outer side of the limiting plate, a telescopic spring connected to the inner wall of the connecting cylinder is provided on the top of the limiting plate, a movable frame is installed on the top of the connecting cylinder, and a U-shaped push frame located between the first guide roller and the second guide roller is provided at the top of the movable frame.

[0013] As a further embodiment of the present invention: the first contact piece is electrically connected to the telescopic cylinder via a wire, and the second contact piece is electrically connected to an external power supply via a wire.

[0014] This invention also discloses a method for winding fabric on a knitting machine for producing knitted fabrics, which uses the aforementioned fabric winding device for a knitting machine and includes the following steps:

[0015] S1: First, pass one end of the fabric through the tension adjusting roller group and pull it to the bottom of the guide roller group. Then, wrap the fabric below the guide roller group around the outside of the roll shaft.

[0016] S2: The fabric winding shaft is driven by the drive unit on the main body of the winding device. The fabric is wound up by the rotation of the fabric winding shaft. After the fabric is wound up, the fastening and locking device is activated. The operation of the fastening and locking device is used to fix the fabric located below the guide roller group.

[0017] S3: The fabric below the guide roller group is stretched by the operation of the stretching connector. Then, the cutter is moved horizontally by the operation of the cutter drive to cut the fabric below the guide roller group.

[0018] S4: After the cutting is completed, the fastening and locking device is activated to make one end of the fabric on the roll shaft lose its fixation. At this time, the one end of the fabric connected to the knitting machine is limited by the fastening and locking device.

[0019] S5: Remove the finished fabric roll and replace it. After replacement, activate the fastener to release the limit on one end of the fabric connected to the knitting machine. Then connect one end of the fabric to the roll.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. By setting up a snap-locking device, the servo motor is started. The servo motor drives the third rotating shaft to rotate 90 degrees counterclockwise, so that the first clamping block clamps the fabric between the first guide roller and the first clamping block. The servo motor drives the third rotating shaft to continue rotating 90 degrees counterclockwise, so that the fabric between the second guide roller and the second clamping block is limited. In this way, the fabric between the first guide roller and the second guide roller can be limited. At this time, when the fabric between the first guide roller and the second guide roller is cut, the shearing force on the fabric cannot be applied to the roll shaft. This prevents the fabric rolled up by the roll shaft from being released when the fabric is sheared. At the same time, the end of the fabric connected to the knitting machine is limited, which facilitates the connection of subsequent fabrics to a new roll shaft.

[0022] 2. By setting up a straightening connector, when the servo motor drives the third rotating shaft to rotate 180 degrees, the first contact piece will contact the second contact piece as the third rotating shaft rotates. At this time, the telescopic cylinder is energized and extends. When the U-shaped push frame contacts the fabric between the first and second guide rollers, the telescopic cylinder continues to extend. At this time, the U-shaped push frame will push the fabric between the first and second guide rollers to straighten, so that the fabric cutting area between the first and second guide rollers is in a flat state. This ensures that the cut is flat when the cutter cuts the fabric between the first and second guide rollers, thus improving the flatness of the fabric winding end. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0035] Please see Figures 1-9In this embodiment of the invention, a knitting machine winding device for knitted fabric production includes a support frame 1. A winding device body 2 is mounted on the top of the support frame 1. A winding shaft 3 is provided on the inner side of the winding device body 2. A tension adjusting roller group 5 located on one side of the winding shaft 3 is provided on the inner side of the winding device body 2. A cutter drive 6 is mounted on the top of the winding device body 2. A cutter 7 is provided on the cutter drive 6. A guide roller group 8 located between the tension adjusting roller group 5 and the winding shaft 3 is mounted on the inner side of the winding device body 2. A first connecting frame 9 is mounted on the bottom of the winding device body 2. A fastening locking device connected to the guide roller group 8 is provided on the first connecting frame 9. Second connecting frames 11 are mounted on both sides of the first connecting frame 9. A straightening connector is provided on the second connecting frame 11. An operating table 4 is mounted on one side of the winding device body 2.

[0036] The guide roller group 8 consists of a first guide roller 801 and a second guide roller 802. The first guide roller 801 and the second guide roller 802 are at the same horizontal height, and the cutter 7 is located between the first guide roller 801 and the second guide roller 802.

[0037] In this embodiment: First, one end of the fabric is passed through the tension adjusting roller group 5 and pulled below the guide roller group 8. Then, the fabric below the guide roller group 8 is wound around the outside of the roll shaft 3. The drive unit on the main body 2 of the winding device drives the roll shaft 3 to operate. The rotation of the roll shaft 3 winds up the fabric. After the fabric is wound up, the fastening locking device is activated. The operation of the fastening locking device fixes the fabric located below the guide roller group 8. At this time, the operation of the straightening connector straightens the part of the fabric below the guide roller group 8. After processing, the cutting blade 7 moves horizontally through the operation of the cutting blade drive 6. The movement of the cutting blade 7 cuts the fabric below the guide roller group 8. After cutting, the fastening lock is activated, causing one end of the fabric on the roll shaft 3 to lose its fixation. At this time, the end of the fabric connected to the knitting machine is limited by the fastening lock. Then, the rolled-up roll shaft 3 is removed and replaced. After replacement, the fastening lock is activated, causing one end of the fabric connected to the knitting machine to lose its limit. Then, one end of the fabric is connected to the roll shaft 3.

[0038] Please refer to this carefully. Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6The latching device includes a servo motor 14 mounted on one side of the first connecting frame 9. The output end of the servo motor 14 is connected to a third rotating shaft 28. A drive gear 30 is mounted on one end of the third rotating shaft 28. A first rotating shaft 24 located on one side of the third rotating shaft 28 is rotatably connected to the side of the first connecting frame 9 away from the servo motor 14 via a bearing. A second rotating shaft 25 located on the other side of the third rotating shaft 28 is provided on the first connecting frame 9. A driven gear 22 that meshes with the drive gear 30 is provided on the outer side of the first rotating shaft 24. A sector-shaped guide wheel 18 is mounted on the first rotating shaft 24. The fan-shaped guide wheel 18 has a first guide groove 26 on both sides of its edge. A cam 23 is installed on the second rotating shaft 25. A second guide groove 27 is provided on both sides of the cam 23. The inner sides of the first guide groove 26 and the second guide groove 27 are slidably connected to L-shaped locking pins 21. The top of the L-shaped locking pin 21 is provided with a limiting rod 17 that is slidably connected to the main body 2 of the winding device. The top of the limiting rod 17 above the fan-shaped guide wheel 18 is connected to a first locking block 15 located below the first guide roller 801. The top of the limiting rod 17 above the cam 23 is provided with a second locking block 20 located below the second guide roller 802.

[0039] The first rotating shaft 24, the third rotating shaft 28, and the second rotating shaft 25 are at the same horizontal height. The second rotating shaft 25 is also equipped with a driven gear 22. The third rotating shaft 28 is connected to the first rotating shaft 24 and the second rotating shaft 25 through a drive gear 30 and a driven gear 22. The top of the first locking block 15 and the second locking block 20 are respectively provided with arc-shaped grooves that fit with the first guide roller 801 and the second guide roller 802, and the inner side of the arc-shaped groove is provided with an anti-slip pad. The driven gear 22 and the drive gear 30 have the same diameter.

[0040] In this embodiment: when cutting the fabric, the servo motor 14 is started first. The servo motor 14 drives the third rotating shaft 28 to rotate counterclockwise by 90 degrees, so that the driven gear 22 drives the first rotating shaft 24 and the second rotating shaft 25 to rotate synchronously. When the first rotating shaft 24 rotates 90 degrees, the L-shaped locking pin 21 will slide along the first guide groove 26. At this time, the L-shaped locking pin 21 will move upward under the pressure of the fan-shaped guide wheel 18, so that the limiting rod 17 pushes the first locking block 15 upward, thereby making the first locking block 15... The fabric is clamped between the first guide roller 801 and the first clamping block 15, so that the fabric is in contact with the first guide roller 801 and the first clamping block 15. During this process, the L-shaped locking pin 21 on the inner side of the second guide groove 27 cannot move vertically upward. Then, the servo motor 14 drives the third rotating shaft 28 to continue rotating counterclockwise by 90 degrees. At this time, the L-shaped locking pin 21 on the inner side of the first guide groove 26 is located at the position farthest from the center of the first rotating shaft 24. At this time, the L-shaped locking pin 21 on the inner side of the first guide groove 26 cannot move vertically, while the inner side of the second guide groove 27... The L-shaped locking pin 21 moves upward under the pressure of the protrusion of the cam 23, thereby limiting the fabric between the second guide roller 802 and the second locking block 20. This limits the fabric between the first guide roller 801 and the second guide roller 802, preventing the shearing force on the fabric from acting on the winding shaft 3 when it is cut. This prevents the fabric wound on the winding shaft 3 from releasing when the fabric is sheared, and also ensures that the end of the fabric connected to the knitting machine is subjected to... The limit is used to facilitate the connection of the subsequent fabric to the new roll shaft 3. After the fabric cutting operation is completed, the servo motor 14 drives the third rotating shaft 28 to rotate 90 degrees in the opposite direction so that the fabric between the second guide roller 802 and the second clamping block 20 loses the limit. Then the rolled-up roll shaft 3 can be removed and replaced. After the new roll shaft 3 is installed inside the main body 2 of the winding device, the servo motor 14 drives the third rotating shaft 28 to rotate 90 degrees in the opposite direction again so that the fabric between the first clamping block 15 and the first guide roller 801 loses the limit.

[0041] Please refer to this carefully. Figures 1-9 The straightening connector includes a telescopic cylinder 12 installed at the bottom of the second connecting frame 11. The output end of the telescopic cylinder 12 is connected to a limit plate 33. A connecting cylinder 13 is sleeved on the outside of the limit plate 33. A telescopic spring 19 connected to the inner wall of the connecting cylinder 13 is provided on the top of the limit plate 33. A movable frame 10 is installed on the top of the connecting cylinder 13. A U-shaped push frame 16 located between the first guide roller 801 and the second guide roller 802 is provided at the top of the movable frame 10.

[0042] The straightening connector also includes an annular plate 29 installed on one side of the first connecting frame 9 and located outside the third rotating shaft 28. The inner wall of the annular plate 29 is equipped with a second contact piece 32, and the outer wall of the third rotating shaft 28 is equipped with a first contact piece 31 located inside the annular plate 29.

[0043] The first contact piece 31 is electrically connected to the telescopic cylinder 12 via a wire, and the second contact piece 32 is electrically connected to an external power supply via a wire.

[0044] In this embodiment: when the servo motor 14 drives the third rotating shaft 28 to rotate 180 degrees, the first contact piece 31 will contact the second contact piece 32 as the third rotating shaft 28 rotates. At this time, the telescopic cylinder 12 is energized and extends. When the U-shaped push frame 16 contacts the fabric between the first guide roller 801 and the second guide roller 802, the telescopic cylinder 12 continues to extend. At this time, the U-shaped push frame 16 will push the fabric between the first guide roller 801 and the second guide roller 802 to straighten it, so that the fabric cutting area between the first guide roller 801 and the second guide roller 802 is in a flat state. This ensures that the cut is flat when the cutter 7 cuts the fabric between the first guide roller 801 and the second guide roller 802, thus improving the flatness of the fabric winding end.

[0045] The following describes a method for winding fabric in a knitting machine for producing knitted fabric, based on the aforementioned fabric winding device for knitted fabric production. The method includes the following steps:

[0046] S1: First, pass one end of the fabric through the tension adjusting roller group 5 and pull it below the guide roller group 8. Then, wrap the fabric below the guide roller group 8 around the outside of the roll shaft 3.

[0047] S2: The winding shaft 3 is driven by the drive unit on the main body 2 of the winding device. The rotation of the winding shaft 3 winds up the fabric. When the fabric is broken, the servo motor 14 is started first. The servo motor 14 drives the third rotating shaft 28 to rotate 90 degrees counterclockwise, so that the driven gear 22 drives the first rotating shaft 24 and the second rotating shaft 25 to rotate synchronously. When the first rotating shaft 24 rotates 90 degrees, the L-shaped locking pin 21 slides along the first guide groove 26. At this time, the L-shaped locking pin 21 moves upward under the pressure of the fan-shaped guide wheel 18, so that the limiting rod 17 pushes the first locking block 15 upward, so that the first locking block 15 moves the fabric between the first guide roller 801 and the first locking block 15. The fabric is clamped so that it fits against the first guide roller 801 and the first clamping block 15. During this process, the L-shaped locking pin 21 inside the second guide groove 27 cannot move vertically upward. Then, the servo motor 14 drives the third rotating shaft 28 to continue rotating counterclockwise by 90 degrees. At this time, the L-shaped locking pin 21 inside the first guide groove 26 is located at the position farthest from the center of the first rotating shaft 24. At this time, the L-shaped locking pin 21 inside the first guide groove 26 cannot move vertically. However, the L-shaped locking pin 21 inside the second guide groove 27 moves upward under the pressure of the protrusion of the cam 23, thereby limiting the fabric between the second guide roller 802 and the second clamping block 20. In this way, the fabric between the first guide roller 801 and the second guide roller 802 can be limited.

[0048] S3: When the servo motor 14 drives the third rotating shaft 28 to rotate 180 degrees, the first contact piece 31 will contact the second contact piece 32 as the third rotating shaft 28 rotates. At this time, the telescopic cylinder 12 is energized and extends. When the U-shaped push frame 16 contacts the fabric between the first guide roller 801 and the second guide roller 802, the telescopic cylinder 12 continues to extend. At this time, the U-shaped push frame 16 will push the fabric between the first guide roller 801 and the second guide roller 802 to straighten it, so that the fabric cutting point between the first guide roller 801 and the second guide roller 802 is in a flat state. This ensures that the cutter 7 is in a flat state when cutting the fabric between the first guide roller 801 and the second guide roller 802, thus improving the flatness of the fabric winding end.

[0049] S4: After the fabric cutting operation is completed, the servo motor 14 drives the third rotating shaft 28 to rotate 90 degrees in the opposite direction so that the fabric between the second guide roller 802 and the second clamping block 20 loses its limit.

[0050] S5: Remove the finished fabric roll 3 and replace it. After installing the new fabric roll 3 inside the main body 2 of the winding device, drive the third rotating shaft 28 to rotate 90 degrees in the opposite direction again through the servo motor 14 so that the fabric between the first clamping block 15 and the first guide roller 801 loses its limit.

[0051] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
