Description

Technical Field

[0001] The present invention relates to the technical field of textiles, and in particular to a single-bed warp knitting machine. Background Art

[0002] The basic principle of knitting is to use knitting needles to form loops of yarn, and then interlock the loops to form a knitted fabric. Therefore, the basic structural unit of a knitted fabric is a loop; according to different ways of forming loops in the weft direction and the radial direction, knitting production can be divided into two major categories: weft knitting and warp knitting; warp knitting is a process of using one or several groups of parallel yarns to be fed radially onto all the working needles of a knitting machine and forming loops simultaneously to form a knitted fabric; the knitted fabric woven by this method is called a warp knitted fabric, and the knitting machine that completes this process is called a warp knitting machine.

[0003] In the prior art, sinkers in multiple rows are provided at the bottom of the warp knitting machine, which cooperate with latch needles to ensure loop formation. However, during long-term use, the sinkers continuously drive slight swings through the bottom, and the up and down movements of the latch needles. If impurities or other items fall into the machine during operation, it will cause the sinkers to be uneven, affect loop formation, and even cause the sinkers to break. As a result, replacement or adjustment is required. Adjustment can be directly aligned and measured with tools such as a measuring scale and then squeezed, but replacement requires the damaged sinkers to be disassembled. There are various methods in the prior art. For example, the sinkers and the base are passed through by long elastic threaded members, or the sinker modules are installed. Such methods are relatively convenient for fixing, but still use individual bolts and nuts for fixing. Therefore, the initial installation is more troublesome, but the replacement can be disassembled one by one. In the first method, whether it is the initial installation or the mid-course disassembly, the whole needs to be disassembled. However, in either case, it is relatively slow in the face of different situations. The present application proposes a warp knitting machine with convenient sinker adjustment, which can be quickly fixed during initial installation and can be switched to single disassembly during replacement to ensure adaptation to various situations.

[0007] Preferably, the releasing component includes a through hole on the connecting member for accommodating the first limiting member to be embedded. Protrusions are provided at both the upper and lower ends of the first limiting member. Grooves for accommodating the protrusions to be embedded are provided on the inner walls of the through hole and the jack. Arc-shaped grooves that communicate with the grooves and accommodate the protrusions to be rotatably embedded are provided in the through hole and the jack. A second spring that abuts against the first limiting member is provided on the base at the jack, and the first limiting member is rotatably connected to the base and the connecting member. A first sliding slot that communicates with the arc-shaped groove and the through hole and accommodates the movement of the first limiting member is provided at the bottom of the through hole on the connecting member.

[0008] Preferably, two blocking blocks for closing the second sliding slot and blocking the first limiting member are provided in the second sliding slot on the base. A fourth spring is provided between the blocking block and the base. The surface of the blocking block that fits with the first limiting member is an arc surface. The elastic force of the fourth spring is less than that of the first spring. The blocking block is higher than the second spring.

[0009] Preferably, a second card slot for accommodating the connecting member to be embedded is provided on the base. A second limiting member that is slidably connected to the connecting member and is embedded in the connecting member is provided in the second card slot. The surface of the second limiting member that abuts against the connecting member is an arc surface. A third spring is provided between the second limiting member and the base. A connecting rope is connected to the end of the second limiting member.

[0010] Preferably, the connecting rope extends along the surface of the base toward the bottom of the base, the base is rotatably connected to the body via a rotating rod, an end of the body away from the rotating rod is provided with a driving rod embedded in the base, and the driving rod is clamped with the base via a slidingly connected abutment block.

[0011] Preferably, the driving rod is slidably connected to a transmission wheel, the machine body is provided with a motor 1 which is offset from the transmission wheel and is used to control the rotation of the driving rod, the motor 1 is provided with a driving wheel which meshes with the transmission wheel, and the end of the connecting rope away from the limiting member 2 is connected to the driving wheel.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] Firstly, when using this device for installation, the sinker is installed on the fixing piece in the same way as a normal device, and then the fixing piece is embedded in the card slot 1 of the base to achieve connection, and then the clamping piece is used to limit and fix the fixing piece. At the same time, after using this device, when embedding the card slot 1, the connecting piece is connected to the limiting piece 1 and embedded in the limiting slot of the moving block, the moving block corresponding to the limiting piece 1 is connected, and the connecting piece is pulled backward, so that the connecting piece can move backward through the limiting piece 1 to drive the clamping pieces in all the card slots 1 to clamp the corresponding fixing piece, so as to achieve the effect of fast fixing to the connection, which is compared with the cumbersome installation in the prior art that is fixed one by one by bolts and nuts, and reduces work efficiency;

[0015] Secondly, during operation, if the sinker collapses due to impurities or other items causing high-speed movement, and the collapsed position needs to be replaced separately, the limit piece 1 can be pressed downward to compress the spring 2, and the protrusion on the limit piece 1 moves down and out of the groove, and enters the slide groove 2, and the limit piece 1 is out of the groove restriction. At this time, the spring 1 will push the limit piece 1 forward and slide along the slide groove 2, and the bottom of the limit piece 1 will also move along the spring 2 and be out of the connection piece, thereby releasing the single limit piece 1, thereby releasing the restriction of the fixing part of the damaged part of the sinker. When the whole is installed, the whole restriction can be fixed, and the connecting part can be released when released, and the restriction of all fixing parts can be released with one click. After installation, the limit piece 1 can be released separately by pressing the limit piece 1, which is convenient for overall installation and easy to replace separately if damaged.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention

[0024] A single-bed warp knitting machine, such as Figures 1 - 6As shown, it includes a machine body 1, a comb, a rocker and a central shaft. The rocker is connected to the comb. The machine body 1 is provided with a sinker 2 at the lower end of the comb. The front end of the sinker 2 is provided with latch needles that are slidably connected to the machine body 1 up and down. The sinker 2 is connected to the machine body 1 through a base 3, and the base 3 is rotatably connected to the machine body 1. When installing the sinker 2 after normal use of this type of equipment, after embedding the sinker 2 into the fixing member 4, it is fixed to the base 3 through bolts and nuts. Thus, the shaft arranged at the bottom of the machine body 1 drives rotation, driving the base 3 to rotate. The base 3 drives the fixing member 4 and the sinker 2 to move to achieve angle adjustment. And when disassembly is required, the bolts and nuts need to be disassembled one by one. Another method is to connect the sinker 2 to the base 3 one by one, and by inserting and fixing steel wires on the side of the base 3, and at the same time fixing with screws. There are several fixing members 4 between the base 3 and the sinker 2. The base 3 is provided with a first clamping groove 5 for accommodating the embedding of several fixing members 4. The first clamping groove 5 is provided with two clamping members 6 for clamping the fixing member 4. The ends of the two clamping members 6 away from the fixing member 4 are staggered with each other. A push rod 7 is passed through the staggered part of the two clamping members 6. The two clamping members 6 are provided with a first guiding groove 8 for accommodating the movement of the push rod 7 at the staggered part. A moving block 9 for pulling the push rod 7 to move is slidably connected to the base 3. And the two clamping members 6 are rotatably connected to the base 3. The fixing member 4 is provided with a limiting groove 10 for accommodating the embedding of the clamping member 6. The base 3 is provided with a limiting component for quickly restricting the fixing member 4. After using this device, during installation, the sinker 2 is fixed to the fixing member 4 one by one. At the same time, the fixing member 4 is embedded into the first clamping groove 5 of the base 3. At the same time, the moving block 9 is pushed so that the moving block 9 drives the push rod 7 to move. The push rod 7 moves backward along the first guiding groove 8 of the two clamping members 6, pulling the clamping members 6 to rotate. The clamping members 6 rotate along the rotation point. Thus, the two clamping members 6 at one end of the push rod 7 approach, and the clamping members 6 at the fixing member 4 also approach and are embedded into the limiting groove 10. In this way, the fixing member 4 is clamped by the two clamping members 6 and embedded into the limiting groove 10 to achieve the effect of clamping and restricting the fixing member 4.

[0025] A first limiting member 12 for fixing the moving block 9 is provided at the rear end of the base 3, and the first limiting member 12 penetrates through the moving block 9. A jack 13 for accommodating the insertion of the first limiting member 12 is provided on the base 3. A plurality of first limiting members 12 are connected by a connecting member 14. After fixing, the connecting member 14 is connected to the first limiting member 12, so that all the first limiting members 12 are connected through the connecting member 14, and the number of the first limiting members 12 corresponds to that of the moving blocks 9. At this time, the first limiting member 12 is inserted through the hole in the moving block 9, and at the same time, the moving block 9 is restricted by fixing through the connecting member 14, ensuring that the position of the moving block 9 will not shift or become loose when the device operates at high speed, thereby also ensuring the stability of the sinker 2. The limiting assembly includes a first spring 11 between the moving block 9 and the base 3 for pushing the moving block 9. A second chute 15 for accommodating the movement of the first limiting member 12 is provided at the front end of the jack 13. A releasing assembly for releasing the connection between the first limiting member 12 and the connecting member 14 and separately disassembling the fixing member 4 is provided on the base 3. The releasing assembly includes a through hole 16 on the connecting member 14 for accommodating the insertion of the first limiting member 12. Protrusions 17 are provided at both the upper and lower ends of the first limiting member 12. Grooves 18 for accommodating the insertion of the protrusions 17 are provided on the inner walls of the through hole 16 and the jack 13. An arc-shaped groove 34 that is communicated with the groove 18 and accommodates the rotational insertion of the protrusion 17 is provided in the through hole 16 and the jack 13. A second spring 19 that abuts against the first limiting member 12 is provided on the base 3 at the position of the jack 13, and the first limiting member 12 is rotatably connected to the base 3 and the connecting member 14. A first chute 20 that is communicated with the arc-shaped groove 34 and the through hole 16 and accommodates the movement of the first limiting member 12 is provided at the bottom of the through hole 16 on the connecting member 14.At the same time, when the connecting member 14 is connected to the limiting member 12, the limiting member 12 is embedded in the through hole 16, and the protrusion 17 at the upper end of the limiting member 12 is embedded in the groove 18 of the connecting member 14, abutting against the bottom of the groove 18, ensuring that the limiting member 12 cannot directly detach from the connecting member 14 forward, because the inner wall at the bottom of the groove 18 blocks the limiting member 12 from moving downward. Therefore, the limiting member 12 is opposite to each moving block 9, and after passing through the end of the moving block 9, the connecting member 14 is pulled backward, so that the moving block 9 is driven to move and the push rod 7 is pulled at the same time, driving the clamping member 6 to clamp and fix the fixing member 4, thereby the limiting member 12 is opposite to the socket 13 of the base 3, and the protrusion 17 at the bottom of the limiting member 12 is also opposite to the groove 18 of the socket 13 of the base 3. At this time, the connecting member 14 and several limiting members are connected. 12 moves downward at the same time, achieving the effect of fixing the limit piece 12, and then the connecting piece 14 moves down to fit the base 3 and embed into the slot 21. At the same time, when embedding into the slot 21, it will abut against the arc surface of the limit piece 22, and push the limit piece 22 outward along the arc surface. After being completely embedded in the slot 21, the groove on the connecting piece 14 is opposite to the limit piece 22. At this time, it is separated from the obstruction of the connecting piece 14, and the limit piece 22 will be embedded in the connecting piece 14 to limit and fix the connecting piece 14. After this arrangement, the connecting piece 14 is fixed and cannot move, and at the same time, it supports and limits the limit piece 12 with the groove 18 in the through hole 16 of the base 3. At the same time, after the limit piece 12 cannot move, it can limit the moving block 9, ensuring that the moving block 9 always keeps the effect of pulling the push rod 7 so that the clamping member 6 clamps the fixing member 4.

[0026] The base 3 is located in the second chute 15 and is provided with two blocking blocks 32 for closing the second chute 15 and blocking the first limiting member 12. A fourth spring 33 is provided between the blocking block 32 and the base 3. The surface of the blocking block 32 in contact with the first limiting member 12 is an arc surface. The elastic force of the fourth spring 33 is less than that of the first spring 11. The blocking block 32 is higher than the second spring 19. Conversely, during operation, if the sinker 2 is damaged due to some impurities, a local single first limiting member 12 can be rotated so that the convex block 17 on the first limiting member 12 rotates along the groove 18 into the arc-shaped groove 34. At the same time, when it moves to the bottom of the arc-shaped groove 34, the arc-shaped groove 34 is communicated with the first chute 20 at the bottom. The jack 13 on the base 3 is then disengaged from the blocking of the groove 18 and can move forward directly, thus getting out of the blocking of the groove 18. At the same time, the first limiting member 12 moves downward to compress the second spring 19 and is opposite to the blocking block 32 and fits with the arc surface of the blocking block 32. At this time, after being released from the restriction of the through hole 16 of the disconnecting member 14, the elastic force of the first spring 11 between the moving block 9 and the base 3 will directly push the moving block 9 forward and drive the first limiting member 12 to move, push open the blocking block 32 and compress the fourth spring 33, and the second chute 15 is opened to accommodate the movement of the first limiting member 12. After canceling the restriction on the moving block 9, the push rod 7 is reset, canceling the push on the clamping member 6, and the clamping member 6 is driven to reset, canceling the clamping on the fixing member 4, so that the fixing member 4 and the sinker 2 can be directly pulled out for replacement. After disassembly, replace with a new one. After inserting the new fixing member 4 and sinker 2 into the first card slot 5, manually pull out the first limiting member 12 outward, then push the moving block 9 to the lower end of the disconnecting member 14, and re-embed the first limiting member 12 along the through hole 16 of the disconnecting member 14. After the convex block 17 at the bottom of the first limiting member 12 moves downward along the groove 18, after rotating the first limiting member 12, the convex block 17 rotates along the arc-shaped groove 34 and is communicated with the through hole 16 to move downward, and then rotate again so that the convex block 17 at the upper end of the first limiting member 12 is opposite to the groove 18 of the disconnecting member 14 again. At this time, re-embed the first limiting member 12 into the moving block 9 and continue to move downward to the jack 13 of the base 3 to be fixed again. Compared with the prior art, when the first limiting member 12 can be disassembled individually, it is necessary to disassemble the bolts and nuts one by one, which is more inconvenient. And for a device that can be disassembled with one key, after local damage, it is still necessary to release the limit of all the fixing members 4, so it is all more inconvenient. However, the present application can be disassembled with one key and can also be disassembled one by one, so as to adapt to various situations and increase practicality.

[0027] A second card slot 21 for accommodating the embedding of the connecting member 14 is provided on the base 3. A second limiting member 22 embedded in the connecting member 14 is slidably connected in the second card slot 21. The surface of the second limiting member 22 in contact with the connecting member 14 is an arc surface. A third spring 23 is provided between the second limiting member 22 and the base 3. A connecting rope 24 is connected to the end of the second limiting member 22. After such a setting, when disassembly is required, by pulling the connecting rope 24 outwards and driving the second limiting member 22 to move backwards to disengage from the connecting member 14, the restriction on the connecting member 14 is cancelled. Thus, the connecting member 14 can be directly pulled out upwards, directly driving the first limiting member 12 to disengage from the moving block 9. At the same time, all the first limiting members 12 are driven to cancel the restriction on the moving block 9, so that the limit of all the moving blocks 9 can be released with one key, and the moving block 9 will be automatically pushed back to its original position by the first spring 11. The push rod 7 is reset, and the corresponding clamping member 6 is also brought back to its original position, canceling the restriction on the fixing member 4. Thus, the fixing member 4 and the sinker 2 can be taken out.

[0028] The connecting rope 24 extends along the surface of the base 3 towards the bottom of the base 3. The base 3 is rotatably connected to the machine body 1 through a rotating rod 25. One end of the machine body 1 away from the rotating rod 25 is provided with a driving rod 26 embedded in the base 3. The driving rod 26 is clamped with the base 3 through an abutting block 27 connected by a sliding connection. A transmission wheel 28 is slidably connected to the driving rod 26. On the machine body 1, there is a first motor 29 which is arranged in a staggered manner with the transmission wheel 28 and is used to control the rotation of the driving rod 26. A driving wheel 30 meshing with the transmission wheel 28 is arranged on the first motor 29. After the normal installation, the sinker 2 drives the first motor connected to the rotating rod 25 on the machine body 1 to start, thereby driving the base 3 to rotate and driving the driving rod 26 to rotate together through the abutting block 27. When the machine body 1 is running, the base 3 can be continuously driven to swing by the motor. The motor can be a servo motor or other motors that can accurately control the forward and reverse rotation, so as to ensure that the rotation angle of the base 3 and the repeated swing can be accurately controlled. The motor can be connected to the transmission rod through a connector such as a gear set. This is the prior art and will not be elaborated here. Secondly, if the machine is stopped and the angle of the sinker 2 of the base 3 needs to be adjusted separately, the motor driving the rotating rod 25 can be turned off, and manual fine-tuning can be carried out through a wrench or tool. First, the angle is raised to reach the required position. After the machine body 1 is continued to be opened, the base 3 is driven to swing by the motor. Through the above settings, when the number of forward and reverse rotations of the motor is the same as the angle, but the initial angle of the base 3 is adjusted differently, the swing amplitude can be ensured to be different. In this way, the base 3 driving the sinker 2 to rise can reach the required degree. A kit rotatably connected to the driving rod 26 is arranged at the end of the driving rod 26. The transmission wheel 28 can rotate freely after moving to the kit. Secondly, when disassembly is required, the machine body 1 can be used to control the transmission wheel 28 to mesh with the driving wheel 30. In the normal state, the transmission wheel 28 is located on the kit. At the same time, a cylinder for pushing the transmission wheel 28 to move is arranged between the transmission wheel 28 and the machine body 1. Therefore, the machine body 1 opens the cylinder to push the transmission wheel 28 to move forward from the kit to mesh with the driving wheel 30. An elastic member and an abutting block are arranged in the transmission wheel 28. In this way, when moving, the abutting block is pushed by the elastic member to clamp the driving rod 26, so as to ensure the connection between the transmission wheel 28 and the driving rod 26. When the first motor 29 is started, the driving rod 26 and the base 3 can be driven to rotate and rise through the driving wheel 30 driving the meshing transmission wheel 28, thereby moving away from the cloth weaving and needle shedding position of the machine body 1, which is convenient for disassembly. One end of the connecting rope 24 away from the second limiting member 22 is connected to the driving wheel 30. A second guiding groove 31 for accommodating the connecting rope 24 to be embedded and guiding the movement of the connecting rope 24 is arranged on the base 3. And the driving wheel 30 is smaller than the transmission wheel 28.During disassembly, the driving wheel 30 rotates to wind up the connecting rope 24, so that the second limiting member 22 releases the restriction on the connecting member 14. The above setting achieves the effect of automatic release. When the adjusting base 3 moves away from the machine body 1, the restriction on the connecting member 14 is released synchronously. Then, the connecting member 14 can be directly disassembled from the first limiting member 12, and the fixing member 4 and the sinker 2 can be disassembled. The connecting rope 24 is elastic by itself. When the base 3 swings, the swinging amplitude is not enough to pull the connecting rope 24, but when the driving wheel 30 rotates, the connecting rope 24 is wound up. After the above setting, it is ensured that during installation, multiple modules are formed by connecting the sinker 2 and the fixing member 4 in advance. This state is basically ready-made in the prior art. The modular sinker 2 and fixing member 4 are inserted into the first clamping groove 5. At the same time, the first limiting member 12 is connected to the connecting member 14, and the first limiting member 12 is inserted into the moving block 9, so as to pull the moving block 9 to quickly drive the clamping member 6 to clamp, achieving the effect of one-key fixing of the sinker 2. Secondly, during disassembly, a single fixing member 4 can be disassembled separately. And during overall disassembly, after the driving wheel 30 rotates to drive the base 3 to rotate, the winding of the driving wheel 30 causes the second limiting member 22 to cancel the restriction on the connecting member 14, achieving the effect of one-key release of the fixing.
