Description

Technical Field

[0001] This invention belongs to the field of warp knitting machine technology, and in particular to a warp knitting machine pattern transverse movement device. Background Technology

[0002] During the warp knitting process, a lateral movement device is required. Existing lateral movement devices achieve lateral movement by swinging the swing arm. When the swing arm is short, it is easy to cause a large lateral movement of the single needle bed warp knitting machine, which reduces the stability and speed of the machine operation.

[0003] Among related technologies, a search revealed a Chinese patent document (authorization announcement number CN206814963U) for a warp knitting machine's convex disc type transverse transmission device, comprising a knitting base, a transverse mechanism, a transverse control mechanism, a transmission mechanism, and an oil display mechanism; the transverse mechanism includes a sliding base block, multiple sets of copper sliders, and multiple top balls corresponding to the multiple sets of copper sliders that control the transverse movement of the warp knitting machine's combs; the transmission mechanism includes a knitting wheel housing, a pair of meshing knitting worm gears, a worm, a transmission synchronous pulley, a synchronous pulley locking ring, and a worm front cover plate; the transverse control mechanism includes a convex-shaped knitting wheel core, a convex-shaped base plate, a knitting wheel shaft, a cam disc composed of multiple cam plates, a lead screw, and a locking ring; the oil display mechanism is located on the surface of the outer wall of the knitting wheel housing. This invention solves the problem of oil leakage in the current convex disc type warp knitting transverse movement mechanism on the market, saves costs and is durable. However, the device does not take into account the short length of the swing arm, which causes a large transverse movement of the single needle bed warp knitting machine, reducing the stability and speed of the machine operation. Summary of the Invention

[0004] The purpose of this invention is to provide a warp knitting machine pattern transverse movement device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a warp knitting machine pattern transverse movement device, comprising: The transverse movement mechanism for warp knitting machines includes a connecting rod and a U-shaped support frame. Fixed bearings are embedded and fixedly connected to the two inner side walls of the support frame. The inner rings of the two fixed bearings are interference-fitted with the connecting rod. Several connecting rings are connected to the side of the connecting rod. A plug rod is connected to the top surface of the connecting ring. An L-shaped hollow bottom slider arm is sleeved on the side of the plug rod. A fixing bolt is threaded to the side of the slider arm. The threaded end face of the fixing bolt abuts against the plug rod. An L-shaped mounting seat is connected to the top surface of the slider arm. A top ball is connected to the inner side wall of the mounting seat. A groove is opened on the end face of the slider arm. Two rotating blocks are rotatably connected to the inner wall of the groove of the slider arm. A fixed wheel with strong magnetism is connected to the adjacent side of the two rotating blocks. The transmission mechanism used in warp knitting machines for weaving patterns, and for driving the traverse mechanism.

[0006] Preferably, the transmission mechanism includes a support base and a U-shaped fixing frame, with the top surface of the support base connected to the fixing frame.

[0007] Preferably, the two inner side walls of the fixing frame are embedded with fixed connection limit bearings, and the inner rings of the two limit bearings are interference-fitted with connecting shafts.

[0008] Preferably, a cam disk is connected to the side of the connecting shaft. The cam disk is composed of several cam plates, and the number of cam plates is equal to the number of fixed wheels.

[0012] Preferably, the outer wall of the connecting box is rotatably connected to the connecting shaft, and a transmission wheel is connected to the end face of one of the connecting blocks.

[0013] Compared with the prior art, the technical effects and advantages of the present invention are as follows: The modified warp knitting pattern transverse movement device significantly improves the stability of the warp knitting machine, meeting the maintenance requirements of single-needle bed warp knitting machines with large transverse movement and increasing the stability of machine use. Under the condition of a certain required transverse movement distance, the longer the swing arm, the smaller the swing range angle of the swing arm. This results in a smaller difference between the maximum and minimum outer diameters of the corresponding cam profile. Therefore, by taking a longer swing arm length, the swing range angle of the swing arm is made smaller, solving the problem of poor dynamic characteristics of the direct-acting follower caused by the motion of the direct-acting cam mechanism, while meeting the requirements of knitting with a large transverse movement and increased knitting speed.

[0014] This warp knitting machine weaving transverse movement device reduces manufacturing costs, simplifies the structure, and controls production costs. Attached Figure Description

However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0019] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this invention, and are explained here together.

[0020] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0021] To address the issue of excessive lateral movement in single-needle-bed warp knitting machines, which reduces machine stability and speed when the swing arm of the lateral movement device is too short, please refer to [link to relevant documentation]. Figures 1 to 5 The structure of the device body includes: The transverse movement mechanism 1 used for warp knitting machine weaving includes a connecting rod 3 and a U-shaped support frame 2. Fixed bearings 4 are embedded and fixedly connected to the two inner side walls of the support frame 2. The inner rings of the two fixed bearings 4 are interference-fitted with the connecting rod 3. Several connecting rings 5 ​​are connected to the side of the connecting rod 3. A plug rod 6 is connected to the top surface of the connecting ring 5. An L-shaped hollow bottom slider arm 7 is sleeved on the side of the plug rod 6. A fixing bolt 8 is threaded to the side of the slider arm 7. The threaded end face of the fixing bolt 8 abuts against the plug rod 6. An L-shaped mounting seat 11 is connected to the top surface of the slider arm 7. A top ball 12 is connected to the inner side wall of the mounting seat 11. A groove is opened on the end face of the slider arm 7. Two rotating blocks 9 are rotatably connected to the inner wall of the groove of the slider arm 7. A fixed wheel 10 with strong magnetism is connected to the adjacent side of the two rotating blocks 9. The transmission mechanism 13 is used for warp knitting machine weaving patterns and is used to drive the transverse movement mechanism 1.

[0022] In this embodiment, the transmission mechanism 13 drives the lateral movement mechanism 1 to move, providing conditions for the warp knitting machine to weave patterns. With several connecting rings 5 ​​and insert rods 6 connected, the slider arm 7 can rotate around the connecting rod 3 as its axis. During transmission, the mounting base 11 and the top ball 12 move laterally. The support frame 2 and two fixed bearings 4 fix the rotational position of the connecting rod 3, improving the structural stability of the device components. Furthermore, the insert rod 6 extends into the inner cavity of the slider arm 7, causing the slider arm 7 to move upwards and downwards along the path of the insert rod 6, increasing the height of the slider arm 7. With the swing distance of the fixed slider arm 7 reduced, the swing angle of the slider arm 7 is reduced. This reduces the required drop between the maximum and minimum outer diameters of the corresponding cam disk 18, thus solving the problem of poor dynamic characteristics of the direct-acting follower caused by the motion of the direct-acting cam mechanism. The fixed bolt 8 moves along the thread path of the slider arm 7, so that the threaded end face of the fixed bolt 8 is tightly abutted against the side of the plug rod 6. Under the action of friction, the relative position of the plug rod 6 and the slider arm 7 is fixed, preventing the slider arm 7 from falling off and improving the structural stability of the device components.

[0023] Specifically, the transmission mechanism 13 includes a support base 14 and a U-shaped fixed frame 15. The top surface of the support base 14 is connected to the fixed frame 15. The two inner side walls of the fixed frame 15 are embedded with fixed limit bearings 16. The inner rings of the two limit bearings 16 are interference-fitted with connecting shafts 17.

[0024] In this embodiment, the support base 14 is trapezoidal in shape, and a semi-circular groove is provided on the bottom surface of the support base 14, so that the support base 14 provides support and fixation for the fixing frame 15. The two limiting bearings 16 are respectively distributed on the two inner side walls of the fixing frame 15, so that the two limiting bearings 16 fix the rotation position of the connecting shaft 17, providing conditions for the relative rotation of the connecting shaft 17 and the fixing frame 15, and improving the structural stability of the device components.

[0025] Specifically, a cam disk 18 is connected to the side of the connecting shaft 17. The cam disk 18 is composed of several cam plates, and the number of cam plates is equal to the number of fixed wheels 10. The outer curved surface of the fixed wheel 10 is magnetically connected to the cam plates.

[0026] In this embodiment, there is a height difference between the maximum and minimum outer diameters of the cam profiles of several cam plates, which causes the fixed wheel 10 to move during the rotation of the cam plates. During the transmission process, the slider arm 7 swings. Several cam plates are combined to form a cam disk 18. The number of cam plates corresponds one-to-one with the number of fixed wheels 10. The cam plates are made of iron, which facilitates the magnetic attraction between the cam plates and the fixed wheels 10. The fixed wheels 10 have strong magnetism, and the magnetic attraction between the fixed wheels 10 and the cam plates is strong.

[0027] Specifically, a connecting box 19 is welded to the side of the fixing frame 15, and cylindrical connecting blocks 22 are rotatably connected to the two inner walls of the connecting box 19. A worm gear 21 is connected to the adjacent side of the two connecting blocks 22.

[0028] In this embodiment, two connecting blocks 22 are distributed on two parallel side walls of the connecting box 19, fixing the rotational position of the two connecting blocks 22. With the connection of the two connecting blocks 22, the rotational position of the worm 21 is fixed, and the two end faces of the worm 21 are in rotational frictional contact with the side walls of the connecting box 19, further enhancing the rotational stability of the worm 21 and preventing the worm 21 from shaking or deviating.

[0029] Specifically, the worm 21 meshes with the worm wheel 20, the side of the worm wheel 20 is fixedly connected to the connecting shaft 17, the outer wall of the connecting box 19 is rotatably connected to the connecting shaft 17, and a transmission wheel 23 is connected to the end face of one of the connecting blocks 22.

[0030] In this embodiment, the transmission wheel 23 is connected to an external belt. Under the drive of an external power device, the transmission wheel 23 rotates, which drives the worm gear 21 to rotate, causing the worm wheel 20 to rotate, and causing several cam plates to rotate around the connecting shaft 17 as the axis. During the transmission process, the transverse movement of the drive transverse mechanism 1 is realized.

[0031] Working principle When using this warp knitting machine's lateral movement device, the user drives the transmission wheel 23 to rotate via a belt connection. Under the connection of the connecting block 22, the worm gear 21 rotates, causing the worm wheel 20 to drive the connecting shaft 17 to rotate. This causes several cam plates to rotate around the connecting shaft 17 as the axis, while the fixed wheel 10 rolls on the surface of the cam plates. During the transmission process, the slider arm 7 rotates around the connecting rod 3 as the axis, realizing the lateral movement of the device and providing lateral movement conditions for the knitting process. Move the slider arm 7 along the path of the connector rod 6, adjust the extension length of the slider arm 7 and the connector rod 6, and move the fixing bolt 8 along the thread path of the slider arm 7. During the movement of the fixing bolt 8, the end face of its threaded part abuts against the connector rod 6, fixing the relative position of the connector rod 6 and the slider arm 7.
