Description

Technical Field

[0001] The present application relates to the technical field of textile equipment, and in particular to a mobile warp let-off frame for a warp knitting machine. Background Art

[0002] A warp knitting machine is a textile machine that forms a fabric with a certain structure and flat pattern by longitudinally weaving one or more sets of warp yarns and transversely interweaving weft yarns.

[0003] The warp knitting process mainly includes three processes: warp feeding, weaving and winding. The warp knitting machine includes a frame and a warp feeding device and a weaving device installed on the frame; the warp feeding device includes a disc head, a driving mechanism for driving the disc head to rotate, and a combing bar for dividing the yarn. When letting off the warp, the warp yarn is led out from the disc head, passed through the tension device, combing bar and other components, and arranged and combed in parallel according to the predetermined order and density. The combed warp yarn is interwoven with the warp yarn and the weft yarn through the weaving device to form a fabric of a certain width.

[0004] When it is necessary to weave fabrics of different lengths, more warps are needed to meet production needs. However, a fixed number of warps are installed on the warp knitting machine. When the required number of warps exceeds the maximum capacity of the warp knitting machine, it must be replaced with a large warp knitting machine with more warps, which is troublesome to operate. Utility Model Content

[0005] In order to improve the defect that it is troublesome to adjust the warp head, the present application provides a mobile warp let-off frame for a warp knitting machine.

[0006] The present application provides a mobile let-off frame for a warp knitting machine, which adopts the following technical solution:

[0007] A mobile let-off frame for a warp knitting machine, comprising:

[0008] A mobile frame, comprising a frame body and rollers installed at the bottom of the frame body;

[0009] The yarn winding mechanism comprises a support shaft detachably connected to the frame and a plurality of winding drums sleeved on the support shaft, wherein the inner diameter of the winding drum is larger than the outer diameter of the support shaft, and the winding drum is used for winding the warp yarn;

[0010] The driving mechanism includes a driving roller rotatably connected to the frame and a driving member driving the driving roller to rotate. The winding drum slides downward under its own weight until the warp yarn abuts against the driving roller. When the driving roller rotates, it can drive the winding drum to rotate; and

[0011] The wire dividing mechanism comprises a wire dividing spring connected to the frame, the wire dividing spring is parallel to the supporting shaft, and the spiral coil of the wire dividing spring can allow the warp yarn to pass through.

[0012] By adopting the above technical solution, each section of warp yarn is wound on the reel separately, and the support shaft and the frame body are detachably connected, so that the corresponding number of reels can be sleeved on the support shaft according to production needs, and the operation is convenient and fast; because the inner diameter of the reel is larger than the diameter of the support shaft, the reel will automatically overlap the driving roller, and the support shaft can play a limiting role to prevent the reel from falling off the driving roller during the warp knitting process; the warp yarn on the reel abuts the driving roller, and the driving roller can drive the reel to rotate when the driving member rotates, so that the warp yarn is drawn out from the reel and sent into the warp knitting machine through the spiral coil of the dividing spring for weaving, and each reel can abut on the driving roller separately, so even if the thickness of the warp yarn on the reel is inconsistent, it can be driven to rotate, and the adaptability is wide; the dividing spring arranges and separates multiple sections of warp yarn according to a predetermined order and spacing, ensuring that each section of warp yarn will not interfere with each other or knot when it is sent to the warp knitting machine. The entire warp feeding frame can be moved to different warp knitting machines to meet different production needs.

[0013] Optionally, the frame body has a fixing plate, the fixing plate is provided with a mounting groove, and the mounting groove has a notch for the support shaft to enter from top to bottom.

[0014] By adopting the above technical solution, the support shaft can directly enter or leave the installation groove through the notch, so as to overlap on the fixed plate, so as to realize the detachable connection between the support shaft and the frame, making the operation of replacing the reel more convenient and quick, and improving the efficiency of the entire warp knitting process. Because the inner diameter of the reel is larger than the support shaft, the reel may not contact the support shaft during the warp feeding process, and the external force on the support shaft is small, so it can be directly overlapped on the fixed plate.

[0015] Optionally, both ends of the support shaft along the length direction are provided with external threads, and a first fastening nut which is screwed onto the support shaft and pressed against the fixing plate is provided.

[0016] By adopting the above technical solution, the two ends of the support shaft are locked and abutted against the fixed plate by the first fastening nut, thereby limiting the movement of the support shaft, and further avoiding the situation where the support shaft may move when some reels may contact the support shaft, thereby ensuring the normal rotation of other reels and further improving the stability of the warp feeding process.

[0017] Optionally, the number of the driving rollers is two and they are horizontally spaced apart and arranged on the frame, and the reel abuts between the two driving rollers.

[0018] By adopting the above technical solution, the number of driving rollers is set to two and they are located on both sides of the winding drum respectively, and the direction of the two driving rollers needs to be set to be consistent, so as to better support and drive the winding drum to rotate and improve the stability of the warp feeding process.

[0019] Optionally, a gear is coaxially arranged at one end of the driving roller along the length direction, a transmission chain is sleeved between the two gears of the two driving rollers, and the driving member is connected to one of the driving rollers.

[0020] By adopting the above technical solution, the two driving rollers only need one driving part to drive through the cooperation of the transmission chain and the gears, which not only saves energy and reduces consumption, but also ensures the synchronous rotation of the two driving rollers, thereby improving the stability of the reel rotation and ensuring the quality of the finished textile product.

[0021] Optionally, the yarn winding mechanism further includes an adjusting component, wherein the adjusting component includes a limit plate slidably connected to the support shaft and a locking component for locking the limit plate to slide.

[0022] By adopting the above technical solution, because the inner diameter of the reel is large, the reel may move along the axial direction of the support shaft when it is sleeved on the support shaft. The sliding limit plate can push all the reels together, and then the locking component is used to lock the limit plate to slide, thereby limiting the horizontal movement of the reel during the warp feeding process, thereby reducing the possibility of the reel jumping and improving the stability of the warp feeding.

[0023] Optionally, the limit plate is sleeved on the support shaft, and the locking component also includes a pin movably connected to the limit plate along the radial direction of the support shaft and an elastic member driving the pin to move toward the support shaft, and locking holes for the pin to be inserted are opened along the axial array on the support shaft.

[0024] By adopting the above technical solution, the limit plate is sleeved and can slide on the support shaft, and the limit plate can also slide away from the support shaft to facilitate the replacement of the reel. When unlocking the limit plate, you only need to pull the latch. When the latch is released, the latch can be driven by the elastic part to automatically insert into the corresponding locking hole, thereby fixing the limit plate on the support shaft. No tools are required for operation, which is more convenient and quick.

[0025] Optionally, the line branching mechanism also includes a vertical plate connected to the frame and a hook connected to the vertical plate, the hook includes a hooking portion for connecting the line branching spring and an adjusting portion connected to the vertical plate and movable along the horizontal direction, and the adjusting portion is threadedly connected with a second fastening nut that is respectively tightened on both sides of the vertical plate.

[0026] By adopting the above technical solution, the length of the branch line spring can be adjusted through the horizontally adjustable hook, and then the pitch of the branch line spring can be adjusted to adapt to different warp yarns, and the adjustment operation is simple.

[0027] Optionally, the line dividing mechanism further comprises a support bar connected to the vertical plate and passing through the line dividing spring along the length direction of the line dividing spring.

[0028] By adopting the above technical solution, the support strip through which the branching spring is arranged can support the branching spring, reducing the possibility of deformation of the branching spring caused by the warp yarn passing through the branching spring, thereby ensuring the tension of the warp yarn and the stability of the warp feeding.

[0029] In summary, the present application includes at least one of the following beneficial effects:

[0030] 1. Each section of warp yarn is wound on the reel separately, and the corresponding number of reels are sleeved on the support shaft according to production requirements. The reel will automatically overlap the driving roller, and the warp yarn on the reel will abut against the driving roller. When the driving member rotates, the driving roller can drive the reel to rotate, so that the warp yarn is drawn out from the reel and sent into the warp knitting machine through the spiral coil of the wire dividing spring for weaving. The disassembly of the support shaft and the adjustment of the wire dividing spring are convenient and quick, which improves the production efficiency;

[0031] 2. The entire warp let-off frame can be moved to different warp knitting machines to meet different production needs;

[0032] 3. Each reel can be respectively abutted against the driving roller, so even if the thickness of the warp yarn on the reel is inconsistent, it can be driven to rotate, with wide adaptability;

DETAILED DESCRIPTION

[0039] The following is combined with Figure 1-4 This application is described in further detail.

[0040] Reference Figure 1 The embodiment of the present application discloses a mobile warp feeding frame for a warp knitting machine, comprising a mobile frame 1 and a winding mechanism 2, a driving mechanism 3 and a line dividing mechanism 4 installed on the mobile frame 1; the winding mechanism 2 comprises a support shaft 21 detachably connected to the frame body 11 and a plurality of reels 22 sleeved on the support shaft 21, the inner diameter of the reels 22 is larger than the outer diameter of the support shaft 21, and the reels 22 are used to wind the warp yarn 5; the driving mechanism 3 comprises a driving roller 31 rotatably connected to the frame body 11 and a driving member 32 driving the driving roller 31 to rotate, the reels 22 slide downward under their own weight until the warp yarn 5 abuts on the driving roller 31, and the driving roller 31 can drive the reels 22 to rotate when rotating; the line dividing mechanism 4 is used to comb the warp yarn 5 drawn from the reels 22. The warp yarn 5 is wound on the reels 22 respectively, and the corresponding number of reels 22 are sleeved on the support shaft 21 according to production requirements. Compared with adjusting a larger volume of the disk head, the operation is convenient and quick.

[0041] Reference Figure 1 and Figure 2 The mobile frame 1 includes a frame body 11, which includes a horizontal frame, a vertical pole for supporting the horizontal frame, and a roller 12 installed at the bottom of the vertical pole. The roller 12 is preferably a universal wheel with a self-locking structure. The entire warp let-off frame can be moved to the front of different warp knitting machine bodies 6 and fixed by the universal wheel, and then the warp yarn 5 is arranged and fed into the warp knitting machine, which can meet different production needs.

[0042] Reference Figure 2 A fixed plate 14 is provided on both sides of the horizontal frame along the length direction. The number of the fixed plates 14 can be multiple. The winding mechanism 2 and the driving mechanism 3 are configured as a warp feeding unit. The required number of warp feeding units can be installed on the fixed plate 14 according to needs.

[0043] Specifically, refer to Figure 2 and Figure 3 , the fixing plate 14 is provided with a mounting groove 141, and the inner diameter of the mounting groove 141 is consistent with the outer diameter of the support shaft 21. In one embodiment, the mounting groove 141 is set as a circular groove, and the support shaft 21 can be installed between the two fixing plates 14 in the horizontal direction; in this embodiment, in order to improve the convenience of operation, the mounting groove 141 is set as a U-shaped groove, and the U-shaped opening of the mounting groove 141 forms a notch 142 for the support shaft 21 to enter from top to bottom. The support shaft 21 can directly enter or leave the mounting groove 141 through the notch 142, so as to overlap on the fixing plate 14, so as to realize the detachable connection between the support shaft 21 and the frame 11, so that the operation of replacing the reel 22 is more convenient and quick, and the efficiency of the entire warp knitting process is improved. Because the inner diameter of the reel 22 is larger than the support shaft 21, the reel 22 may not contact the support shaft 21 during the warp feeding process, and the external force on the support shaft 21 is small, so it can be directly overlapped on the fixing plate 14.

[0044] Furthermore, the support shaft 21 is arranged to be fixed to the fixed plate 14 so as to avoid the movement of the support shaft 21 caused by the possibility that some of the winding drums 22 may contact the support shaft 21, thereby ensuring the normal rotation of other winding drums 22 and improving the stability of the warp feeding process. Figure 3 The support shaft 21 is provided with external threads 211 at both ends along the length direction, and a first fastening nut 23 that is tightened against the fixing plate 14 is screwed on the support shaft 21. One end of the support shaft 21 is preferably provided with two first fastening nuts 23 that are respectively tightened against the two sides of the fixing plate 14, so as to limit the movement of the support shaft 21; a gasket can be provided between the first fastening nut 23 and the fixing plate 14 to improve the stability of the connection structure.

[0045] Because the reel 22 is abutted against the driving roller 31 through the warp yarn 5, the warp yarn 5 will gradually decrease during the warp feeding process. In order to ensure that the warp yarn 5 can continuously contact the driving roller 31, the reel 22 is preferably a straight cylindrical shape. The warp yarn 5 can be evenly wound on the reel 22 through textile equipment such as a warping machine, and then the required number of reels 22 are sleeved on the support shaft 21, and each reel 22 can be respectively abutted against the driving roller 31, so even if the thickness of the warp yarn 5 on the reel 22 is inconsistent, it can be driven to rotate, and it has wide adaptability.

[0046] Reference Figure 3 and Figure 4The support shaft 21 can play a limiting role to prevent the reel 22 from falling off the driving roller 31 during warp knitting. In order to reduce the possibility of lateral movement or jumping of the reel 22 with a larger inner diameter, the yarn winding mechanism 2 also includes an adjusting component 24. The number of adjusting components 24 can be two and they are respectively located on both sides of the outermost reel 22 on the support shaft 21. The adjusting component 24 includes a limiting plate 241 slidably connected to the support shaft 21 and a locking component 242 for locking the sliding of the limiting plate 241. The sliding limiting plate 241 can push all the reels 22 together, and then the locking component 242 is used to lock the sliding of the limiting plate 241, so that the rotation of the reel 22 can be more stable, thereby improving the stability of warp feeding.

[0047] Specifically, refer to Figure 4 The limit plate 241 is sleeved on the support shaft 21, and the locking component 242 also includes a pin 2421 on the limit plate 241 that is movably connected to the radial direction of the support shaft 21 and an elastic member 2422 that drives the pin 2421 to move toward the support shaft 21. The limit plate 241 is provided with a movable groove for the pin 2421 to move, and the elastic member 2422 is preferably a spring. The elastic member 2422 is located in the movable groove and sleeved on the pin 2421. The support shaft 21 is provided with locking holes 212 for the pin 2421 to be inserted in the axial array, and the end of the pin 2421 is provided with a chamfer to facilitate insertion into the locking hole 212; in addition, the top of the support shaft 21 can be set to a plane, and the locking hole 212 is opened on the plane. The shape of the through hole on the limit plate 241 for the support shaft 21 to pass through is consistent with the cross-sectional shape of the support shaft 21, so as to facilitate the positioning of the pin 2421 and insert it into the locking hole 212. The limit plate 241 can slide away from the support shaft 21 to facilitate the replacement of the reel 22. When unlocking the limit plate 241, it is only necessary to pull the latch 2421. When the latch 2421 is released, the latch 2421 can be driven by the elastic member 2422 to automatically insert into the corresponding locking hole 212, thereby fixing the limit plate 241 on the support shaft 21. No tools are required for operation, which is more convenient and quick.

[0048] In other embodiments, the number of the driving roller 31 may be one and the driving roller 31 may be located directly below the supporting shaft 21 .

[0049] In this embodiment, in order to ensure the stability of the driving roller 31 driving the yarn roller to rotate, refer to Figure 2 and Figure 3, there are two driving rollers 31 and they are arranged horizontally and spaced apart on the frame 11, the reel 22 abuts between the two driving rollers 31, and the two driving rollers 31 need to be set to have the same direction of rotation, so as to better support and drive the reel 22 to rotate, and improve the stability of the warp feeding process. Further, a gear 33 is coaxially arranged at one end of the driving roller 31 passing through the fixed plate 14 in the length direction, and a transmission chain 34 is sleeved between the two gears 33 of the two driving rollers 31. The driving member 32 is preferably a motor, and the output end of the driving member 32 is fixedly connected to one end of one of the driving rollers 31 connected to the gear 33 through a coupling. The portion of the driving roller 31 passing through the fixed plate 14 can be provided with a bearing to reduce the rotation resistance of the driving roller 31. Only one driving member 32 is needed for driving, which is not only more energy-saving and consumption-reducing, but also can ensure the synchronous rotation of the two driving rollers 31, thereby improving the stability of the rotation of the reel 22, and thereby ensuring the quality of the textile product.

[0050] Reference Figure 2 and Figure 4 The line dividing mechanism 4 includes a vertical plate 42 fixedly connected to both ends of the horizontal frame along the length direction, a hook 43 connected to the vertical plate 42, a line dividing spring 41 connected between the two hooks 43, and a support bar 45 passing through the line dividing spring 41 along the length direction of the line dividing spring 41. The support bar 45 can be installed on the vertical plate 42. The line dividing spring 41 is parallel to the support shaft 21. The support bar 45 is made of a steel bar. The spiral coil of the line dividing spring 41 can allow the warp yarn 5 to pass through. The support bar 45 can reduce the possibility of deformation of the line dividing spring 41 when the warp yarn 5 passes through the line dividing spring 41. The line dividing spring 41 arranges and separates multiple sections of warp yarn 5 in a predetermined order and spacing to ensure that each section of warp yarn 5 will not interfere with each other or get knotted when being fed into the warp knitting machine.

[0051] In order to adapt to different numbers of warp yarns 5, the hook 43 includes a hook portion 431 for connecting the dividing line spring 41 and an adjusting portion 432 connected to the vertical plate 42 for horizontal movement. The adjusting portion 432 is threadedly connected with a second fastening nut 44 that is respectively tightened against both sides of the vertical plate 42. The length of the dividing line spring 41 can be adjusted through the horizontally adjustable hook 43, and then the pitch of the dividing line spring 41 can be adjusted, and the adjustment operation is simple.

[0052] The implementation principle of a mobile let-off frame for a warp knitting machine in the embodiment of the present application is as follows:

[0053] According to production requirements, the movable frame 1 is moved to the front of the warp knitting machine body 6 where the number of warp yarns 5 needs to be increased, and the warp yarns 5 are respectively wound on the reels 22, and the support shaft 21 and the frame body 11 are detachably connected, so that the corresponding number of reels 22 can be sleeved on the support shaft 21, and then the sliding limit plate 241 abuts all the reels 22 on one support shaft 21 together; the reel 22 will automatically overlap on the driving roller 31, and the warp yarn 5 on the reel 22 abuts against the driving roller 31. When the driving roller 31 is rotated by the driving member 32, it can drive the reel 22 to rotate, thereby leading the warp yarn 5 from the reel 22 and sending them into the warp knitting machine through the spiral coils of the dividing spring 41 for weaving. The entire adjustment process is convenient and fast, which effectively improves the production efficiency.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
