Description

Technical Field

[0001] The present invention relates to the technical field of textile machinery, and in particular to a segmented wide-width warp beam feeding device and method for a high-speed warp knitting machine. Background Art

[0002] Currently, the warp let-off mechanism of high-speed warp knitting machines on the market generally uses traditional narrow warp beams after the warp yarns have been straightened. These beams are arranged in series by passing warp tubes through the inner holes of each beam, and then hoisted and fixed to the warp beam frame of the high-speed warp knitting machine for warp knitting production. When this type of warp beam series arrangement requires high requirements, it is necessary to align the warp beam transmission keys with the keyways within the narrow warp beams one by one. For high-speed warp knitting machines of 340 inches and above, 15 or more sets of narrow warp beam discs are required to be connected in series. At the same time, due to the narrow width of the traditional warp beam discs, there are large gaps between the warp beam discs after multiple sets of warp beam discs are stacked in series, and the feeding angles of the side yarns on both sides of each warp beam are large. The narrow warp beam discs have always had problems such as uneven warping tension and static electricity generated by friction between the yarn and the disc edge during warping, which directly affect dyeing, cause color difference in the grey fabric, and reduce the quality of the warp knitted products. In addition, due to defects such as fixing methods, self-wear, and tension errors, the traditional 15 sets of narrow warp beams often cause different raw materials of each set of narrow warp beam discs to be used up at the same time, resulting in serious waste, horizontal and vertical stripes in the grey fabric, and reduced quality. The patent of the present invention adopts an independent wide-width warp beam structure to make up for the above-mentioned defects, which not only improves the quality of the grey fabric, but also reduces labor and costs. In addition, the traditional narrow-width warp beams need to be produced one by one during warping, and the production efficiency is relatively low; for wide-width warp knitting machines, when multiple groups of combined warping are required, the number of supporting warping equipment required is relatively high, which greatly improves the production efficiency. Summary of the Invention

At the same time, it solves the problem that static electricity generated by the friction between the yarn and the disc in the traditional several groups of warp beam heads in series causes color difference in the subsequent dyeing process of the grey cloth, thereby improving the quality of the grey cloth. In addition, the three groups of wide-width warp beam components are connected with the same core, and the warp feeding amount is more accurate. While meeting the traditional grey cloth weaving of the same specifications, the machine shape becomes smaller, saving space, and the warp beam head does not need to be inserted into the warp beam tube, reducing the worker's operating procedures and labor, further solving the gap generated by the series connection of several groups of warp beam discs, solving the horizontal and vertical stripes of the grey cloth, and reducing the weight of the wide-width warp beam itself and the machine load.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside” are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] A high-speed warp knitting machine with a segmented wide-width warp beam feeding device, such as Figure 1 、 2 4, including a high-speed warp knitting machine warp shaft frame, a segmented wide-width warp shaft assembly 8, an intermediate support assembly, a warp feed transmission device, and a segmented pulling assembly 9; the high-speed machine warp shaft frame includes a left warp feed support seat 1, a right warp feed support seat 2 and two groups of intermediate support seats 3, the bottom of the intermediate support seat 3 is fixed to the upper end of the supporting ground beam 4; the left column 5 and the right column 6 are respectively fixedly connected to the left warp feed support seat 1 and the right warp feed support seat 2; the segmented wide-width warp shaft assembly 8 is three groups arranged in series with each other , respectively fixed on the left warp feeding support seat 1, the right warp feeding support seat 2 and the two groups of intermediate support seats 3; the warp feeding transmission device is fixedly installed on the outer side of the right warp feeding support seat 2, and is fixedly connected to the right flange shaft head 8-3 of the segmented wide-width warp beam assembly 8 through the warp feeding active shaft head 19 arranged on the right support seat 2; the segmented pulling assembly 9 is divided into three widths, which are composed of groups of transmission pulling rollers, and are parallel to and one-to-one corresponding to the axis center lines of the segmented wide-width warp beam assembly 8.

[0032] Specifically, by adopting independent wide-width warp beams, namely segmented wide-width warp beam assemblies 8, compared with traditional narrow-width warp beams, wide-width warp beams can significantly reduce the gaps between warp beams, thereby reducing the edge yarn feeding angle, improving the yarn tension distribution, and making the tension in the warping process more uniform, which directly improves the quality of the grey cloth, reduces the color difference and quality degradation caused by uneven tension and static electricity problems, and the segmented wide-width warp beam assembly 8 enables each group of warp beams to use raw materials more evenly, avoiding the problem of raw materials not being used up at the same time due to factors such as traditional narrow-width warp beam fixing methods, self-wear and tension errors, significantly reducing raw material waste, and at the same time reducing the horizontal and vertical stripes on the grey cloth, thereby improving the overall quality of the product. The segmented wide-width warp beam assembly 8 allows the warping process to be carried out in parallel, rather than the traditional narrow-width warp beams produced one after another, which greatly improves the warping efficiency. When a wide-width warp knitting machine requires multiple groups of combined warping, the number of required supporting warping equipment is reduced, further improving the overall production efficiency. The invention relates to a warp knitting machine which is a warp knitting machine which is a warp knitting machine which is a warp knitting machine which is a warp knitting machine which is a warp knitting machine. The invention also relates to a warp knitting machine which is a warp knitting machine which is a warp knitting machine which is a warp knitting machine which is a warp knitting machine which is a warp knitting machine. The invention also relates to a warp knitting machine which is a warp knitting machine which is a warp knitting machine which is a warp knitting machine which is a warp knitting machine which is a warp knitting machine which is a warp knitting machine

[0033] As a preferred embodiment of the above, Figure 1 、 3 As shown, the segmented wide-width warp beam assembly 8 is composed of three warp beam bodies of the same specifications connected in series, each warp beam body includes a warp beam core tube 8-1 and is welded and fixed to the left flange shaft head 8-2 and the right flange shaft head 8-3 respectively.

[0034] Specifically, the segmented wide-width warp beam assembly 8 is composed of three warp beam bodies of the same specification connected in series, which not only simplifies the manufacturing process, but also ensures the compatibility and consistency between the warp beam bodies. The structure of each warp beam body includes a warp beam core tube 8-1, which plays the role of supporting and transmitting torque. The two ends of the warp beam core tube 8-1 are respectively fixedly connected to the left flange shaft head 8-2 and the right flange shaft head 8-3 by welding, which not only ensures the strength and stability of the connection, but also avoids production problems caused by loosening or wear. The left flange shaft head 8-2 and the right flange shaft head 8- 3, the design enables the segmented wide-width warp beam assembly 8 to be conveniently connected and fixed with other components such as the warp let-off transmission device, and also provides convenience for the introduction and derivation of the warp yarn, ensuring the smooth flow of the warp yarn during the warping and let-off processes. The design of three warp beams of the same specifications connected in series makes the entire segmented wide-width warp beam assembly 8 more balanced and stable during operation, and the gaps between the warp beams are minimized, reducing the yarn tension fluctuations and yarn friction problems caused by excessive gaps, improving the quality of the grey cloth, and extending the service life of the warp beams.

[0035] As a preferred embodiment of the above, Figure 1 、 3 As shown, the warp beam discs 8-4 located on both sides of the warp beam core tube 8-1 are fixed to the left flange shaft head 8-2 and the right flange shaft head 8-3 by a plurality of fixing bolts 8-5.

[0036] Specifically, the use of fixing bolts 8-5 ensures a secure connection between the warp beam disc 8-4 and the flange shaft head, thereby enhancing the structural strength of the entire warp beam assembly. During high-speed operation, this secure connection can effectively resist vibration and impact, maintaining the stability and precision of the warp beam. When the warp beam disc 8-4 needs to be replaced due to wear or other reasons, this can be easily achieved by loosening the fixing bolts 8-5. This design simplifies the maintenance process, reduces maintenance costs, and reduces production losses caused by downtime for maintenance. As an important part of yarn management, the secure fixation of the warp beam disc 8-4 makes the introduction and export of yarn smoother. At the same time, due to the tight connection between the warp beam disc 8-4 and the flange shaft head, the slippage and jump of the yarn on the warp beam are reduced, improving the efficiency and precision of yarn management. By adjusting the number and position of the warp beam discs 8-4, it is possible to flexibly adapt to the production needs of warp knitting products of different specifications and types.

[0037] As a preferred embodiment of the above, Figure 4 As shown, the head half end of the left flange shaft head 8-2 is provided with a rolling bearing 8-7, and the half connecting sleeve 8-6 is fixed to the left flange shaft head 8-2 by a screw bolt 8-8, and the inner gear of the rolling bearing 8-7 is firmly fixed; the area surrounded by the two warp beam discs 8-4 and the outer side of the warp beam core tube 8-1 forms a yarn gathering area.

[0038] Specifically, a disc slot 8-9 is provided for hoisting, and a rolling bearing 8-7 is provided through the head half end of the left flange shaft head 8-2. The main purpose of this design is to bear and support the huge load generated by the warp beam assembly during high-speed operation, reduce friction and wear, and extend service life. The rolling contact mode of the rolling bearing 8-7 has higher operating accuracy and stability than the sliding contact mode, which can ensure the smoothness and accuracy of the warp beam during rotation. The half connecting sleeve 8-6 is used as a connecting component and is firmly fixed to the left flange shaft head 8-2 by the fixing bolt 8-8. The design of the half connecting sleeve allows the entire shaft assembly to be installed and removed without completely disassembling, thereby improving the convenience of maintenance. Through the tightening action of the screw bolt 8-8, the half connecting sleeve 8-6 not only firmly fixes the inner gear of the rolling bearing 8-7, but also ensures a tight connection between the entire shaft head and the warp beam core tube, preventing loosening and deviation. The area surrounded by the two warp beam discs 8-4 and the outer side of the warp beam core tube 8-1 forms a yarn collection area. This area is designed to effectively manage and collect yarns, ensuring an orderly and smooth yarn introduction and withdrawal process. The presence of the yarn collection area not only improves yarn management efficiency, but also reduces yarn chaos and entanglement on the warp beam, thereby improving production efficiency and product quality. At the same time, it also provides convenient conditions for subsequent yarn processing and finishing.

[0039] As a preferred embodiment of the above, Figure 3 As shown, the warp let-off transmission device includes a disc head driving member 10 and a reducer 11. The reducer 11 is installed on a reducer fixing plate 12 and fixed to the outer side of the warp let-off right support seat 2.

[0040] Specifically, the warp drive 10 serves as the power source for the warp let-off mechanism, enabling precise speed and position control based on commands from the control system. This precise control is crucial for maintaining stable warp tension during the let-off process, reducing yarn breakage, and improving product quality. The reducer 11, installed between the warp drive 10 and the let-off mechanism, converts the high-speed, low-torque output of the warp drive into a low-speed, high-torque output to meet the actual speed and torque requirements of the warp let-off mechanism of the warp knitting machine.

[0041] As a preferred embodiment of the above, Figure 1 、 3 As shown, a warp let-off active shaft head 19 is provided on the warp let-off right support seat 2, and the warp let-off synchronous wheel 13 is fixed to the head end of the warp let-off active shaft head 19 through a tensioning sleeve 16, and is connected to the transmission synchronous wheel 14 on the reducer drive shaft 18 by a synchronous belt 15 for driving the wide-width warp beam assembly to rotate and feed yarn.

[0042] Specifically, a second tensioning sleeve 17 is provided to adjust the left and right directions of the synchronous belt 15, and the rolling bearing 20 cooperates with the rotation of the warp feeding active shaft head 19. The warp feeding right support seat 2 is used as an important supporting component of the warp feeding transmission device. Its design needs to ensure sufficient strength and stability to withstand various forces and torques generated during the transmission process. The warp feeding synchronous wheel 13 is fixed to the head end of the warp feeding active shaft head 19 through the tensioning sleeve 16, ensuring a close connection between the synchronous wheel and the shaft head, and facilitating subsequent adjustment and replacement. When the reducer receives the power from the disk head drive component, the power is transmitted to the reducer drive shaft 18 through its internal gear transmission mechanism. The reducer drive shaft 18 drives the transmission synchronous wheel 14 to rotate, and then transmits the power to the warp feeding synchronous wheel 13 through the synchronous belt 15. The rotation of the warp feeding synchronous wheel 13 drives the warp feeding active shaft head 19 to rotate, and finally drives the wide-width warp beam assembly to rotate for yarn feeding operation.

[0043] As a preferred embodiment of the above, Figure 1 、 3 As shown, the three groups of segmented pulling assemblies 9 correspond one to one with the segmented wide-width warp beam assemblies 8, and the axis lines are parallel to each other. The yarn wound on each group of wide-width warp beams is fed in a vertical direction and is pulled out vertically by the segmented pulling assembly 9 after weaving.

[0044] Specifically, the three groups of segmented pulling components 9 and the segmented wide-width warp beam components 8 have parallel and one-to-one correspondence in their axis lines, ensuring that the yarn on each warp beam component can be pulled independently and accurately, avoiding mutual interference and uneven tension between the yarns. The axis lines of all components are parallel to each other, which is conducive to maintaining the stability and consistency of the entire system and reducing vibration and wear that may be caused by non-parallel axes. The yarn wound on each group of wide warp beams is fed in a vertical direction. This feeding method simplifies the yarn path, reduces friction and loss of the yarn during transmission, and is also conducive to maintaining the tension and directionality of the yarn. The woven yarn is pulled out vertically by the segmented pulling component 9. Vertical pulling helps maintain the shape and tension of the yarn and reduces yarn twisting and breakage that may be caused by improper pulling direction.

[0045] A method for sending off warps with a segmented wide warp beam for a high-speed warp knitting machine comprises fixing a half connecting sleeve 8-6 and a right flange shaft head 8-3 to the left and right shaft heads of a warping machine and locking them. The warping head is driven by a warping head driving member 10 to rotate clockwise to wind the yarn. The warping machine automatically stops after warping the yarn to a specified number of meters or turns.

[0046] Warping 3 segmented wide warp beam assemblies 8 according to user needs;

[0047] The three segmented wide-width warp beam assemblies 8 are directly hoisted into the warp knitting machine on the warp beam frame of the high-speed warp knitting machine, and the positions are adjusted and firmly fixed, and the yarn feeding work is started;

[0048] The warped whole group of segmented wide-width warp beam assemblies 8 are hoisted one by one onto the warp beam frame of the high-speed warp knitting machine starting from the right end;

[0049] The right flange shaft head 8-3 of the segmented wide-width warp beam assembly 8 is hoisted into the warp-letting active shaft head 19, and the warp-letting active shaft head 19 is provided with a half cover, which is firmly fixed with bolts;

[0050] The left end of the segmented wide-width warp beam assembly 8 is provided with a rolling bearing 8-7 which is hoisted onto the middle support seat 3;

[0051] The left end of the segmented wide-width warp beam assembly 8 is provided with the half connecting sleeve 8-6 which is fixedly connected to the right flange shaft head 8-3 of another group of segmented wide-width warp beam assemblies 8;

[0052] The three groups of segmented wide-width warp beam assemblies 8 are connected and fixed one by one to form a complete group of warp beam assemblies;

[0053] The warp letting transmission device provided on the right warp letting support seat 2 drives the entire warp beam assembly to rotate clockwise to perform the yarn letting-off action.

[0054] Specifically, this solution adopts a segmented wide-width warp beam assembly. Compared with the traditional one-piece cast aluminum disk head, the segmented design makes the system more flexible. The number and length of the warp beam assemblies can be adjusted according to actual needs to adapt to the production of yarns of different specifications and types. In the traditional method, due to the different sizes of the raw yarn bobbins, the yarn tension will change during the warping process, resulting in errors in the outer circumference after the entire winding. In this solution, the yarn tension of each segment of the assembly can be independently controlled through the segmented assembly, which reduces the overall tension change and error and improves the accuracy and uniformity of the warp feeding. In the traditional method, due to tension changes and errors, the yarns on multiple groups of disk heads often cannot be used up at the same time, resulting in waste of raw materials. This solution optimizes the warp feeding method and controls the tension so that the yarns on each group of segmented warp beam assemblies can be consumed more evenly, thereby improving the utilization rate of raw materials. The segmented warp beam assembly in this solution The wide-width warp beam assembly is firmly connected by the half connecting sleeve and the right flange shaft head and other components, and is supported by the warp feeding active shaft head and the intermediate support seat, ensuring the stability and durability of the assembly during rotation. Compared with the clearance fit and wear problems between the warp head and the warp shaft tube in the traditional method, the up and down jumping and inaccurate warp feeding caused by wear are reduced. The segmented warp beam assembly can be directly hoisted onto the warp shaft frame of the warp knitting machine, and the position adjustment and firm fixation are completed. Compared with the complex process of the traditional method that requires multiple warp heads to be put on the warp shaft tube and locked with a clamp, the installation and debugging process of this solution is simpler and faster. Through the combined effect of the above advantages, the method of this solution can significantly improve the production efficiency and product quality of the warp knitting machine. The stable warp feeding process and uniform yarn tension help reduce quality problems such as yarn breakage and yarn skipping, and improve the overall quality of the product.
