Description

Technical Field

[0001] This utility model relates to the field of warp knitting machines, and in particular to a needle bed transmission mechanism for a double needle bed warp knitting machine. Background Technology

[0002] The needle bed of a double needle bed warp knitting machine is the core component of the double needle bed warp knitting machine. The needle bed of the warp knitting machine is equipped with knitting needles. The needle bed needs to be connected through a transmission mechanism to realize the up and down reciprocating motion of the needle bed so that the knitting needles can knit the yarn into fabric.

[0003] However, in the existing technology, the transmission mechanism of the common warp knitting machine needle bed is composed of a linkage frame, a main shaft and a linkage mechanism, and it is installed in the bed part, not connected to the wall panel where the needle bed is installed. Moreover, the structure composed of the linkage frame, the main shaft and the linkage mechanism is complex and difficult to assemble. The linkage mechanism requires oil bath lubrication in the bed and has high sealing requirements. Furthermore, once the linkage mechanism is designed, the movement stroke of the needle bed is fixed and cannot be adjusted. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a needle bed transmission mechanism for a double needle bed warp knitting machine.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a needle bed transmission mechanism for a double needle bed warp knitting machine, comprising a wall panel, wherein a transmission mechanism is installed inside the wall panel, the transmission mechanism comprising a servo motor, a first swing shaft, an eccentric steel sleeve, a bearing, a connecting plate, a swing arm, and a connecting rod, the main body end of the servo motor being installed on one side of the outer wall of the wall panel, the output end of the servo motor being fixedly connected to one end of the first swing shaft, the first swing shaft being rotatably connected inside the wall panel, the eccentric steel sleeve being fitted onto the outer wall of the first swing shaft, the eccentric steel sleeve having an eccentric hole inside, and the first swing shaft passing through the eccentric hole. The connecting plate is sleeved on the outer wall of the eccentric steel sleeve. A circular hole is opened inside the connecting plate. The outer ring of the eccentric steel sleeve is connected to the circular hole through a bearing. The swing arm is rotatably connected to the outer wall of the connecting plate. A second swing shaft is fixedly connected to one side of the inner side of the swing arm. The second swing shaft is rotatably connected to the inner side of the wall panel. The connecting rod is rotatably connected to the outer wall of the swing arm. A needle bed bracket is rotatably connected to the outer wall of the connecting rod. A needle bed plate and a knitting needle plate are installed on the upper surface of the needle bed bracket. A support is fixedly connected inside the wall panel. A guide shaft is fixedly connected to the lower surface of the needle bed bracket. The guide shaft is slidably connected inside the support.

[0006] Furthermore, clamping rings are provided at both ends of the outer wall of the eccentric steel sleeve, and the two clamping rings clamp the eccentric steel sleeve to the outer wall of the first swing shaft.

[0007] Furthermore, a first connecting shaft is fixedly connected to the outer wall of the connecting plate, and the first connecting shaft is rotatably connected inside the swing arm.

[0008] Furthermore, a second connecting shaft is fixedly connected to the outer wall of the swing arm, and the second connecting shaft is rotatably connected inside the connecting rod.

[0009] Furthermore, a third connecting shaft is fixedly connected to the outer wall of the connecting rod, and the third connecting shaft is rotatably connected inside the needle bed bracket.

[0010] Furthermore, the needle bed bracket and the needle bed plate are connected by bolts and threads, and the needle plate is fixedly connected to the outer wall of the needle bed plate.

[0011] This utility model has the following beneficial effects:

[0012] 1. Compared with existing technologies, this patented technology, by setting up a servo motor, a first swing shaft, an eccentric steel sleeve, a connecting plate, a swing arm, a connecting rod, a needle bed bracket, a support, and a guide shaft, allows the servo motor to drive the first swing shaft to rotate when the servo motor is started. This rotation causes the eccentric steel sleeve to rotate and drive the connecting plate to swing. The swing of the connecting plate then drives the swing arm to swing back and forth. The swing of the swing arm further drives the connecting rod to swing back and forth. The support limits the guide shaft, ultimately driving the needle bed bracket and the guide shaft to move up and down reciprocally. By controlling the servo motor through a remote control device, the first swing shaft can rotate 360° or rotate forward and backward within a certain angle range, thereby adjusting the motion stroke of the needle bed bracket. This solution is not only simple in structure but also allows for adjustment of the motion stroke of the needle bed bracket, improving the practicality of the transmission mechanism.

[0013] 2. Compared with the prior art, this patented technology, by setting up a first swing shaft, an eccentric steel sleeve, an eccentric hole, bearings, clamping rings, a connecting plate, and a round hole, allows the eccentric steel sleeve to pass through the connecting plate and multiple bearing arrays to be placed between the eccentric steel sleeve and the round hole. The eccentric steel sleeve passes through the eccentric hole through the first swing shaft and is then clamped at both ends of the eccentric steel sleeve by two clamping rings, thus clamping the eccentric steel sleeve to the outer wall of the first swing shaft. During the rotation of the first swing shaft, which drives the eccentric steel sleeve to rotate, contact between the eccentric steel sleeve and the round hole is avoided. Through the rolling friction of multiple bearings, the friction between the eccentric steel sleeve and the connecting plate is reduced, which plays a role in auxiliary lubrication. There is no need to add oil bath lubrication, which reduces the sealing requirements between the eccentric steel sleeve and the connecting plate.

[0014] 3. Compared with the prior art, this patented technology uses bolts to install the needle bed plate and the knitting needle plate on top of the needle bed bracket. When it is necessary to replace the knitting needle plate with a different model, the bolts can be removed and the needle bed plate with the other model of knitting needle plate can be replaced. In addition, during the reciprocating motion of the needle bed bracket, the support limits the guide shaft, so that the needle bed bracket can move up and down, thereby driving the needle bed plate and the knitting needle plate to move up and down, so as to realize the weaving work.

[0023] Reference Figure 1-6This utility model provides a needle bed transmission mechanism for a double needle bed warp knitting machine: It includes a wall panel 1, inside which a transmission mechanism is installed. The transmission mechanism includes a servo motor 2, a first swing shaft 3, an eccentric steel sleeve 4, a bearing 402, a connecting plate 5, a swing arm 6, and a connecting rod 7. The main body of the servo motor 2 is installed on one side of the outer wall of the wall panel 1. The output end of the servo motor 2 is fixedly connected to one end of the first swing shaft 3. The first swing shaft 3 is rotatably connected inside the wall panel 1 and its rotation is limited inside the wall panel 1. The eccentric steel sleeve 4 is sleeved on the first... The outer wall of the swing shaft 3 has an eccentric hole 401 inside the eccentric steel sleeve 4. The first swing shaft 3 passes through the eccentric hole 401. The eccentric steel sleeve 4 is fitted through the eccentric hole 401 and passes through the outer wall of the first swing shaft 3. The connecting plate 5 is fitted on the outer wall of the eccentric steel sleeve 4. The connecting plate 5 has a circular hole 501 inside. The outer ring of the eccentric steel sleeve 4 is connected to the circular hole 501 by a bearing 402. The eccentric steel sleeve 4 passes through the circular hole 501 inside the connecting plate 5, and multiple bearings 402 are arranged in an array between the circular hole 501 and the outer ring of the eccentric steel sleeve 4. The eccentric steel sleeve 4 and the connecting plate 5 are connected by a bearing 402, avoiding the problem of high friction coefficient caused by direct contact between the eccentric steel sleeve 4 and the connecting plate 5. The rolling friction of the bearing 402 reduces the friction coefficient between the eccentric steel sleeve 4 and the connecting plate 5, thereby indirectly achieving a lubrication effect. There is no need to add oil bath lubrication, which reduces the sealing requirements between the eccentric steel sleeve 4 and the connecting plate 5. The swing arm 6 is rotatably connected to the outer wall of the connecting plate 5, and a second swing shaft 601 is fixedly connected to one side of the inner side of the swing arm 6. The second swing shaft 601 is rotatably connected to the inside of the wall plate 1. The swing arm 6 rotates along the central axis of the second swing shaft 601. The connecting rod 7 is rotatably connected to the outer wall of the swing arm 6. The outer wall of the connecting rod 7 is rotatably connected to the needle bed bracket 8. The upper surface of the needle bed bracket 8 is equipped with a needle bed plate 801 and a knitting needle plate 802. The wall plate 1 is fixedly connected to the inside of the support 9. The lower surface of the needle bed bracket 8 is fixedly connected to the guide shaft 10. The guide shaft 10 is slidably connected to the inside of the support 9. During the reciprocating motion, the needle bed bracket 8 is limited and slid inside the support 9 by the guide shaft 10, thereby realizing the up-and-down reciprocating motion of the needle bed bracket 8.

[0024] The outer walls of the eccentric steel sleeve 4 are provided with clamping rings 403 at both ends. The two clamping rings 403 clamp the eccentric steel sleeve 4 to the outer wall of the first swing shaft 3. The two clamping rings 403 clamp the two ends of the eccentric steel sleeve 4 and clamp the eccentric steel sleeve 4 to the outer wall of the first swing shaft 3. The outer wall of the connecting plate 5 is fixedly connected to the first connecting shaft 502. The first connecting shaft 502 is rotatably connected to the inside of the swing arm 6. The connecting plate 5 and the swing arm 6 are hinged and driven through the first connecting shaft 502. The outer wall of the swing arm 6 is fixedly connected to the second connecting shaft 502. The second connecting shaft 602 is rotatably connected inside the connecting rod 7. The swing arm 6 and the connecting rod 7 are hinged and driven by the second connecting shaft 602. The outer wall of the connecting rod 7 is fixedly connected to the third connecting shaft 701, which is rotatably connected inside the needle bed bracket 8. The connecting rod 7 and the needle bed bracket 8 are hinged and driven by the third connecting shaft 701. The needle bed bracket 8 and the needle bed plate 801 are threadedly connected by bolts 803. The needle plate 802 is fixedly connected to the outer wall of the needle bed plate 801.

[0025] Working principle: In use, the servo motor 2 is started by remote control, which drives the first swing shaft 3 to rotate. During this rotation, the first swing shaft 3 drives the eccentric steel sleeve 4 to reciprocate, further driving the connecting plate 5 to reciprocate and swing at an angle. This, in turn, drives the swing arm 6 to reciprocate and swing around the second swing shaft 601, ultimately causing the connecting rod 7 and the needle bed support 8 to reciprocate. The needle bed support 8 is limited and slides inside the support 9 by the guide shaft 10, thus achieving a vertical reciprocating motion of the needle bed support 8. This, in turn, drives the needle bed plate 801 and the knitting needle plate 802 to reciprocate, achieving the weaving operation. When it is necessary to control the motion of the needle bed support 8, the servo motor 2 is adjusted by the remote control device, allowing the servo motor 2 to rotate 360° or reciprocate in both directions within a certain angle range. The first swing shaft 3 can rotate 360° or reciprocate within a certain angle range, thereby changing the motion stroke of the needle bed support 8. While the first swing shaft 3 rotates, driving the eccentric steel sleeve 4 to rotate, multiple bearings 402 arranged in an array are connected between the outer ring of the eccentric steel sleeve 4 and the circular hole 501 inside the connecting plate 5. This avoids direct contact between the eccentric steel sleeve 4 and the connecting plate 5, preventing an increase in the coefficient of friction. The bearings 402 roll and rub during the rotation of the eccentric steel sleeve 4, thus reducing the coefficient of friction and assisting in indirect lubrication between the eccentric steel sleeve 4 and the connecting plate 5. This solution is not only simple in structure but also achieves the desired change in the motion stroke of the needle bed support 8. Furthermore, it eliminates the need for oil bath lubrication, reducing the sealing requirements between the eccentric steel sleeve 4 and the connecting plate 5 and improving the practicality of the transmission mechanism.
