Description

Technical Field

[0001] The present application relates to the technical field of textile equipment, and in particular to a warp let-off frame of 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 steps: warp feeding, weaving and winding. Figure 1 The warp knitting machine includes a frame 6 and a warp feeding device, a weaving device and a winding device installed on the frame 6; wherein the warp feeding device includes a flower shaft, a driving mechanism for driving the flower shaft to rotate, a disc head 7 fixedly mounted on the flower shaft and a comb bar for dividing the yarn. When letting off the warp, the warp yarn is led out from the disc head 7, and arranged and combed according to a predetermined order and density through a tension device, a comb bar and other components. The combed warp yarn is interwoven with the warp yarn and the weft yarn through a weaving device to form the basic structure of the fabric, and finally wound on a drum through a winding device for subsequent processing and treatment.

[0004] However, when the length of the warp knitted fabric knitted by the warp knitting machine is longer, more disc heads 7 are required. When the required disc heads 7 exceed the maximum number, only a large warp knitting machine with more disc heads 7 can be replaced for knitting, which is troublesome. Utility Model Content

[0005] In order to improve the defect that it is troublesome to adjust the warp head, the present application provides a warp delivery frame of a warp knitting machine.

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

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

[0008] A fixing plate, fixed on the frame;

[0009] The yarn winding mechanism comprises a guide connected to the fixed plate and a braiding shaft connected to the guide along a vertical sliding direction, wherein the braiding shaft is detachably connected to the guide, and a plurality of warp yarns are wound around the braiding shaft at intervals;

[0010] The driving mechanism includes a roller rotatably connected to the fixed plate and a driving member driving the roller to rotate, the braiding shaft slides down on the guide member under its own weight and the warp yarn abuts against the roller, and the roller can drive the braiding shaft to rotate when rotating; and

[0011] The line dividing mechanism is installed on the fixed plate and is used for combing the warp yarns drawn out from the braiding shaft.

[0012] By adopting the above technical scheme, the fixed plate is fixed on the frame of the warp knitting machine to provide stable support for the entire warp feeding frame. The braiding shaft and the guide member are detachably connected to facilitate the supplementary winding of the warp yarn. The number of warp yarns and the length and color of each warp yarn segment can be adjusted according to production needs. The warp yarn is directly wound on the braiding shaft without replacing or adjusting the larger disc head, and the operation is convenient and quick. During the warp feeding process, the braiding shaft is acted upon by its own weight on the guide member so that the warp yarn can be tightly abutted against the rotating roller. When the driving member drives the rotating roller to rotate, the shaft can be rotated, thereby leading the warp yarn from the braiding shaft and being sent into the warp knitting machine through the wire dividing mechanism for weaving. The wire dividing mechanism arranges and separates multiple warp yarn segments in a predetermined order and spacing to ensure that each warp yarn segment will not interfere with each other or become knotted when being sent into the warp knitting machine.

[0013] Optionally, the guide member is provided with a movable groove for the flower braiding shaft to move vertically, a limiting member is arranged on the flower braiding shaft, and an inner wall of the movable groove is provided with a limiting groove for the limiting member to slide vertically.

[0014] By adopting the above technical solution, the axial movement of the braiding shaft can be limited by the cooperation between the limiting member and the limiting groove between the braiding shaft and the guide member, thereby avoiding the movement of the braiding shaft during the warp feeding process that causes changes in the warp tension, density, etc., thereby ensuring the quality of yarn weaving.

[0015] Optionally, the movable groove has a notch for the braiding axis to enter vertically downward, and the notch is expanded.

[0016] By adopting the above technical solution, the braiding shaft enters or leaves the movable groove through the notch vertically, thereby realizing the detachable connection between the braiding shaft and the guide piece, and the notch of the movable groove is expanded, which further improves the convenience of disassembly and assembly of the braiding shaft, thereby better adjusting the number and length of the warp yarns.

[0017] Optionally, the limiting member is a bearing sleeved on the braiding shaft, and the bearing is vertically slidably connected in the limiting groove.

[0018] By adopting the above technical solution, the limiter is set as a bearing with an outer diameter larger than the braiding shaft. While limiting the axial movement of the braiding shaft, it can also reduce the rotational friction of the braiding shaft, avoid the jamming of the braiding shaft, and ensure that the braiding shaft can be driven to rotate when the roller rotates, so as to improve the stability of warp feeding and ensure the quality of textile products.

[0019] Optionally, the guide member is connected to a clamping component at the notch of the movable groove, and the clamping component includes a mounting block detachably connected to the guide member, a first elastic member connected to the mounting block, and an abutment block connected to the first elastic member, and the first elastic member drives the abutment block to move toward the direction of the limiting member.

[0020] By adopting the above technical solution, the mounting block is detachably connected to the guide member, so that the pressing component can be removed to facilitate the disassembly of the braided flower shaft through the notch; the abutment block is driven by the first elastic member to abut against the limiter and has a tendency to push the limiter downward, so that the warp yarn can be tightly abutted against the roller, and the possibility of vibration of the braided flower shaft can be reduced, further improving the stability of the roller drive; the abutment block is also pressed against the outer ring of the bearing, which can further limit the rotation of the outer ring of the bearing, thereby making the braided flower shaft connected to the inner ring of the bearing rotate more smoothly. In addition, the pressing component can also limit the braided flower shaft from detaching from the guide member upward during the warp feeding process, further improving the stability of the warp feeding.

[0021] Optionally, the abutment block is slidably connected in the limiting groove.

[0022] By adopting the above technical solution, the abutment block is set to be slidably connected in the limiting groove, which can guide the driving of the first elastic member, so that the abutment block pushes the bearing more stably, thereby making the warp feeding process more stable.

[0023] Optionally, the guide member is connected to a locking rod movable in a horizontal direction and a second elastic member driving the locking rod to move toward the mounting block, and the mounting block is provided with a locking hole for the locking rod to be inserted.

[0024] By adopting the above technical solution, the locking rod is automatically inserted into the locking hole driven by the second elastic member, so that the mounting block can be fixedly installed on the guide member; when the warp yarn on the braiding shaft is to be adjusted, it is only necessary to pull the locking rod away from the mounting block until it is disengaged from the mounting block, and the entire clamping component can be removed, which is convenient and quick to operate.

[0025] Optionally, the line dividing mechanism includes a line dividing spring connected to the fixed plate, the line dividing spring is parallel to the braiding axis, and the spiral coil of the line dividing spring can allow the warp yarn to pass through.

[0026] By adopting the above technical solution, the line dividing mechanism is directly set as a line dividing spring with a certain length. Each section of warp yarn led out from the braiding axis can pass through the spiral coil of the line dividing spring at intervals, so as to be combed and arranged in sequence. The line dividing spring is wound by a round steel wire. Not only can the density of the spiral coil be adjusted by lengthening and shortening the line dividing spring to adjust the guidance of the warp yarn, but the surface of the line dividing spring is smooth, which can reduce the possibility of wear on the warp yarn. In addition, compared with components such as combs, the line dividing spring has a simpler structure and lower cost.

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

[0028] By adopting the above technical solution, the warp yarn needs to adjust a certain tension through the splitter spring, so the warp yarn will exert a force on the splitter spring, and the splitter spring itself has a deformation force. The splitter spring is inserted through the support bar to support the splitter spring, reducing the possibility of the warp yarn passing through the splitter spring and causing the splitter spring to deform, so as to ensure the tension of the warp yarn and the stability of warp feeding.

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

[0030] 1. The number of warp yarns and the length and color of each warp yarn can be adjusted according to production needs and wound on the braiding shaft at intervals. The braiding shaft and the guide piece are detachably connected, which is convenient for supplementing the winding warp yarn. There is no need to replace or adjust the larger disc head, which is easy and quick to operate.

[0031] 2. The warp yarns are separated and combed by the dividing spring, which has a simple structure and is more convenient for disassembly and assembly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] The following is combined with Figure 2-6 This application is described in further detail.

[0040] Reference Figure 2 The embodiment of the present application discloses a warp-spindle warp-feeding frame of a warp knitting machine, comprising a fixed plate 1, a yarn-winding mechanism 2, a driving mechanism 3 and a line-dividing mechanism 4. The yarn-winding mechanism 2 is fixed on a frame 6 of the warp knitting machine, and comprises a guide member 21 connected to the fixed plate 1 and a braiding shaft 22 connected to the guide member 21 along a vertical sliding manner, the braiding shaft 22 is detachably connected to the guide member 21, and a plurality of warp yarns 5 are wound around the braiding shaft 22 at intervals; the driving mechanism 3 comprises a roller 31 rotatably connected to the fixed plate 1 and a driving member 32 driving the roller 31 to rotate, the braiding shaft 22 slides down on the guide member 21 under its own weight and the warp yarns 5 abut against the roller 31, and the roller 31 can drive the braiding shaft 22 to rotate when it rotates; the line-dividing mechanism 4 is installed on the fixed plate 1 for combing the warp yarns 5 drawn from the braiding shaft 22. The warp yarn 5 is wound with a braiding shaft 22, and the braiding shaft 22 and the guide member 21 are also detachably connected. The number of warp yarns 5 and the length and color of each warp yarn 5 can be adjusted according to production needs. There is no need to replace or adjust the larger disc head 7, and the operation is convenient and quick.

[0041] Reference Figure 2 There are two fixing plates 1, which are fixed on both sides of the frame 6 along the length direction by bolts or welding. A reinforcing plate is also obliquely connected between the fixing plate 1 and the frame 6 to improve the supporting strength. The fixing plate 1 and the reinforcing plate are made of an alloy material with relatively high hardness.

[0042] Reference Figure 3 and Figure 4The yarn winding mechanism 2 and the driving mechanism 3 are configured as a warp feeding unit. The fixed plate 1 may be provided with one warp feeding unit or multiple warp feeding units may be installed at intervals. The warp yarn 5 is directly wound on the braiding shaft 22 by using a warping machine or other equipment. A braiding shaft 22 may be provided with multiple sections of warp yarn 5 at intervals as required. The guide member 21 is provided with a movable groove 211 for the braiding shaft 22 to move vertically. The width of the movable groove 211 is consistent with the diameter of the braiding shaft 22. The movable groove 211 has a notch 213 for the braiding shaft 22 to enter vertically downward. In order to facilitate the disassembly and assembly of the braiding shaft 22 and the adjustment of the warp yarn 5, the notch 213 is expanded upward, so as to play a role in guiding the installation and make the braiding shaft 22 enter better.

[0043] Reference Figure 5 In order to improve the stability of the warp feeding process, both ends of the braiding shaft 22 along the length direction are provided with limit members 23, and the inner wall of the movable groove 211 is also connected to open a limit groove 212 for the limit member 23 to slide vertically. The cooperation between the braiding shaft 22 and the guide member 21 through the limit member 23 and the limit groove 212 can limit the movement and shaking of the braiding shaft 22 along the axial direction, thereby avoiding the movement of the braiding shaft 22 during the warp feeding process to cause changes in the tension and density of the warp yarn 5, thereby ensuring the quality of yarn weaving.

[0044] In other embodiments, the limiting member 23 may be a limiting block fixed on the braiding shaft 22 .

[0045] In this embodiment, the limiting member 23 is preferably a bearing 231 sleeved on the braiding shaft 22, and the bearing 231 is vertically slidably connected in the limiting groove 212. The inner ring of the bearing 231 is tightly sleeved on the braiding shaft 22, and the outer ring of the bearing 231 abuts against the inner wall of the limiting groove 212. The bearing 231 not only plays the effect of limiting the axial movement of the braiding shaft 22, but also reduces the rotational friction of the braiding shaft 22, avoids the jamming of the braiding shaft 22, and ensures that the rotating roller 31 can drive the braiding shaft 22 to rotate when it rotates, so as to improve the stability of warp feeding and ensure the quality of textile products.

[0046] In order to further reduce the possibility of the braiding shaft 22 shaking and improve the stability of the warp letting process, refer to Figure 4 and Figure 5The yarn winding mechanism 2 also includes a clamping component 24 connected to the guide member 21 at the notch 213 of the movable groove 211 and a locking component 25 for connecting the guide member 21 and the clamping component 24. The clamping component 24 includes a mounting block 241 detachably connected to the guide member 21, a first elastic member 242 connected to the mounting block 241, and an abutment block 243 connected to one end of the first elastic member 242 away from the mounting block 241. The first elastic member 242 drives the abutment block 243 to move toward the limit member 23. The first elastic member 242 can be a spring or a rubber pad. A guide column is provided on the mounting block 241. The first elastic member 242 is preferably a spring sleeved on the guide column. The clamping block is preferably slidably abutted against the limit member 23 in the limit groove 212. On the one hand, the clamping component 24 can limit the braiding shaft 22 from moving upward out of the guide member 21 during the warp feeding process, so the mounting block 241 is detachably connected to the guide member 21, thereby facilitating the removal of the clamping component 24 so that the braiding shaft 22 can be disassembled and assembled through the slot 213; on the other hand, the abutment block 243 is driven by the first elastic member 242 to have a tendency to push the bearing 231 downward, thereby enabling the warp yarn 5 to be tightly abutted against the roller 31, and also reducing the possibility of vibration of the braiding shaft 22, further improving the driving stability of the roller 31.

[0047] Moreover, the side of the abutment block 243 that abuts against the outer ring of the bearing 231 can be set to an arc-shaped surface consistent with the curvature of the outer ring of the bearing 231, thereby increasing the contact area and further limiting the rotation of the outer ring of the bearing 231, thereby making the braided shaft 22 connected to the inner ring of the bearing 231 rotate more smoothly.

[0048] In other embodiments, the locking component 25 may be configured as a bolt, and the connecting block and the guide member 21 are connected by the bolt to achieve detachable installation of the pressing component 24 .

[0049] In this embodiment, in order to make the operation more convenient, refer to Figure 4 and Figure 6The locking component 25 includes a locking rod 251 and a second elastic member 252. A plug-in portion 2411 protrudes from the bottom of the mounting block 241. A mounting portion 214 extends horizontally outward from the notch 213 of the movable groove 211 on the guide member 21. A slot 215 for the plug-in portion 2411 is provided on the top surface of the mounting portion 214. A sliding slot connected to the slot 215 is provided on the side of the mounting portion 214 in the horizontal direction. The locking rod 251 is movably connected to the sliding slot. A handle 253 is provided at one end of the locking rod 251 away from the movable groove 211 for easy manual pulling. The second elastic member 252 is a spring sleeved on the locking rod 251. The second elastic member 252 drives the locking rod 251 to move toward the slot 215. A locking hole 2412 is provided on the plug-in portion 2411 for the locking rod 251 to be plugged in. The locking rod 251 is driven by the second elastic member 252 to automatically insert into the locking hole 2412, so that the mounting block 241 can be fixedly mounted on the guide member 21; when the warp yarn 5 on the braiding shaft 22 is to be adjusted, it is only necessary to pull the locking rod 251 away from the mounting block 241 until it is disengaged from the mounting block 241, and the entire pressing component 24 can be removed, which is convenient and quick to operate.

[0050] Reference Figure 3 The driving mechanism 3 includes a roller 31 rotatably connected between the two fixed plates 1 and a driving member 32 driving the roller 31 to rotate. The driving member 32 can be a motor fixed on the fixed plate 1, and the output shaft of the motor is fixedly connected to one end of the roller 31. When the braiding shaft 22 slides down until the warp yarn 5 contacts the roller 31, the driving member 32 starts to drive the roller 31 to rotate, thereby leading the warp yarn 5 from the braiding shaft 22 and feeding it into the warp knitting machine for weaving.

[0051] In other embodiments, the wire dividing mechanism 4 may be a comb-tooth-like structure such as a comb bar that can be used to comb the warp yarn 5 .

[0052] In this embodiment, in order to better adapt to different numbers of warp yarns 5, refer to Figure 3The wire-dividing mechanism 4 includes a vertical rod 43 mounted on the fixed plate 1, and a hook 44 is provided on the vertical rods 43 on the two fixed plates 1 facing the opposite side, and a wire-dividing spring 41 is hung between the two hooks 44, and the wire-dividing spring 41 is parallel to the braiding axis 22, and each section of warp yarn 5 drawn out from the braiding axis 22 can pass through the spiral coil of the wire-dividing spring 41 at intervals, so as to be combed and arranged in sequence and enter the warp knitting machine; a hard support bar 42 is also connected between the two hooks 44, and the support bar 42 passes through the wire-dividing spring 41 along the length direction of the wire-dividing spring 41, and the support bar 42 is used to support the wire-dividing spring 41 to reduce the possibility of deformation of the wire-dividing spring 41, and the support bar 42 can be made of steel bars to ensure the tension of the warp yarn 5 and the stability of warp feeding. The dividing spring 41 is wound by a round steel wire. Not only can the density of the spiral coil be adjusted by lengthening and shortening the dividing spring 41 to adjust the guidance of the warp yarn 5, but the surface of the dividing spring 41 is smooth, which can reduce the possibility of wear on the warp yarn 5. In addition, compared with components such as a comb, the dividing spring 41 has a simpler structure and lower cost.

[0053] The implementation principle of a warp let-off frame of a warp knitting machine in the embodiment of the present application is as follows:

[0054] The fixing plate 1 is fixed on the frame 6 of the warp knitting machine. A braiding shaft 22 can be provided with multiple sections of warp yarn 5 at intervals as needed. The braiding shaft 22 and the guide member 21 can be detachably connected to facilitate the additional winding of the warp yarn 5, and the operation is convenient and quick. During the warp feeding process, the braiding shaft 22 is driven by the guide member 21 under the action of its own weight and the pressing member 24 so that the warp yarn 5 can be closely abutted against the roller 31. When the driving member 32 drives the roller 31 to rotate, the shaft can be rotated, so that the warp yarn 5 is drawn out from the braiding shaft 22 and is sent into the warp knitting machine for weaving after being combed and tensioned by the dividing spring 41. The warp yarn 5 is separated and combed by the dividing spring 41. The structure is simple and the disassembly and assembly are more convenient.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
