[0004] Warp knitting machines generate vibrations when they are working, and traditional warp knitting machines usually have springs around the base to reduce vibrations. However, the vibrations generated by warp knitting machines when they are working are not just longitudinal vibrations, so the springs have a general effect on reducing vibrations of warp knitting machines. Summary of the invention

[0005] In order to improve the vibration reduction effect on a warp knitting machine, the present application provides a vibration reduction device.

[0007] By adopting the above technical solution, the vibration reduction device realizes effective vibration reduction of the warp knitting machine through the combined design of the support feet, upper support plate, lower support plate, fixing parts, upper pillars, lower pillars, vibration reduction springs, support blocks, buffer balls, buffer water bags and buffer columns. The upper support plate and the lower support plate are fixed to the warp knitting machine and the ground through fixing parts to form a stable support structure. The coaxial sliding design of the upper pillar and the lower pillar, in conjunction with the vibration reduction spring, can absorb and disperse the longitudinal vibration energy from the warp knitting machine. The buffer balls and buffer water bags in the support block further enhance the vibration reduction effect. Through the movable connection of the buffer balls and the diaphragm and connecting hole design in the buffer water bag, it can more effectively absorb and disperse other types of vibrations such as lateral and oblique vibrations, further enhance the buffering effect of the vibration of the warp knitting machine, and improve the working stability and service life.

[0008] Optionally, the outer diameter of the lower support is smaller than the inner diameter of the mounting groove.

[0009] By adopting the above technical solution, the outer diameter of the lower support is smaller than the inner diameter of the mounting groove, so that the lower support can slide freely in the mounting groove while maintaining a certain gap, reducing the possibility of excessive friction resistance affecting the vibration reduction effect, and allowing the upper support to better transmit vibration to the buffer column. This design also allows the lower support to be fine-tuned in the mounting groove to meet different vibration reduction requirements. In addition, the existence of the gap can effectively reduce the jamming phenomenon caused by vibration and ensure the normal operation of the vibration reduction device.

[0010] Optionally, a receiving groove for installing the buffer water bag is formed in the support block, and a movable opening connected to the receiving groove is formed at the bottom of the support block, and the buffer column passes through and moves in the movable opening; A baffle is disposed on the outer peripheral side of the buffer column, and the baffle is in sliding contact with the top wall of the accommodating groove.

[0011] By adopting the above technical solution, the receiving groove formed in the support block provides installation space for the buffer water bag, and the setting of the movable opening allows the buffer column to pass through and move therein, reducing the possibility of the support block contacting the buffer column, and the design of the baffle can reduce the possibility of the buffer water bag overflowing from the movable opening. When vibration occurs, the buffer column drives the buffer ball to squeeze the buffer water bag, so that the buffer water bag absorbs and disperses the vibration energy. This design improves the stability and reliability of the vibration reduction device.

This design allows the buffer column to perform multi-directional buffering movement when subjected to vibration, improves the flexibility and adaptability of the vibration reduction device, and reduces the possibility of the buffer column driving the baffle plate to collide with the support block.

[0014] Optionally, the upper support plate is provided with a control plate that slides up and down in the mounting groove, the peripheral side wall of the control plate is in sliding contact with the peripheral side groove wall of the mounting groove, and the top of the damping spring abuts against the bottom of the control plate; A transmission plate is slidably arranged in the upper support plate, an elastic support member for supporting the transmission plate is arranged in the upper support plate, and a counterweight ball is movably connected to the top of the transmission plate; The upper support plate is provided with a friction strip, and the side wall of the transmission plate is slidably connected to the friction strip; The upper support plate is provided with a control component, and when the counterweight ball vibrates and drives the transmission plate to slide downward, the control component controls the control plate to squeeze the damping spring; When the transmission plate slides upward, the control assembly controls the control plate to move away from the damping spring.

[0015] By adopting the above technical solution, the combined design of the control plate, transmission plate, elastic support, counterweight ball and control assembly arranged in the upper support plate realizes the dynamic adjustment of the vibration damping spring. When the warp knitting machine is vibrated, the vibration of the counterweight ball drives the transmission plate to slide downward, and through the action of the control assembly, the control plate squeezes the vibration damping spring to increase the vibration damping effect. When the vibration weakens or stops, the transmission plate slides upward under the action of the elastic support, and the control assembly controls the control plate to move away from the vibration damping spring and restore the initial state. This design can automatically adjust the vibration damping effect according to the vibration conditions, thereby improving the intelligence and adaptability of the vibration damping device.

When the transmission plate slides downward due to vibration, the support spring is compressed; when the vibration weakens or stops, the support spring releases energy and pushes the transmission plate to slide upward to the initial position. This design ensures stable movement and rapid reset of the transmission plate, and improves the reliability and durability of the vibration reduction device.

[0020] Optionally, the fixing member is a fixing bolt, and there are multiple fixing bolts that are respectively penetrated through the lower support plate, and the fixing bolts are threadedly connected to the ground.

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-6 This application is described in further detail.

[0026] The embodiment of the present application discloses a vibration reduction device, which is applied to a warp knitting machine.

[0027] The inventor of the present application discovered that warp knitting machines generate vibrations when they are working, and traditional warp knitting machines usually have springs set around the base for vibration reduction. However, the vibrations generated by warp knitting machines when they are working are not only longitudinal vibrations, so the springs have a general vibration reduction effect on warp knitting machines. For this reason, the present application mainly adopts the following vibration reduction device to achieve an improved vibration reduction effect on the warp knitting machine. The present application is further described in detail below.

[0028] See also Figure 1 The vibration reduction device includes a support leg 1. The support leg 1 is fixedly connected to the bottom of the warp knitting machine. There are multiple support legs 1 and they are respectively located at the four corners of the bottom of the warp knitting machine. The bottom of the warp knitting machine is formed with a clamping groove. There are multiple clamping grooves and they are evenly spaced along the circumference with the support leg 1 as the center. In the embodiment of the present application, there are four clamping grooves.

[0029] See also Figure 2The vibration reduction device further includes an upper support plate 2, a lower support plate 3 and a fixing member. The upper support plate 2 is clamped in the clamping groove, and the upper support plate 2 corresponds to the clamping groove one by one. The lower support plate 3 is arranged opposite to the upper support plate 2, and the lower support plate 3 abuts against the ground, and the lower support plate 3 corresponds to the upper support plate 2 one by one. The fixing member is a fixing bolt 31, and there are a plurality of fixing bolts 31, which are respectively penetrated through the lower support plate 3, and the fixing bolts 31 are threadedly connected to the ground to achieve fixed connection of the lower support plate 3.

[0030] See also Figure 3 The vibration reduction device further includes an upper support 21, a lower support 32 and a vibration reduction spring 33. The upper support 21 is fixedly connected to the middle position of the bottom of the upper support plate 2, and the lower support 32 is fixed to the middle position of the top of the lower support plate 3. The diameter of the lower support 32 is smaller than the diameter of the upper support 21, and the lower support 32 is coaxially arranged with the upper support 21. The upper support 21 is formed with a mounting groove 211, and the mounting groove 211 penetrates downward to the outside of the upper support 21, and the lower support 32 extends into the mounting groove 211. The central axis of the lower support 32 coincides with the central axis of the mounting groove 211, and the outer diameter of the lower support 32 is smaller than the inner diameter of the mounting groove 211.

[0031] The outer diameter of the lower support 32 is smaller than the diameter of the mounting groove 211, and the damping spring 33 is fixedly connected to the top of the lower support 32. The damping spring 33 is located in the mounting groove 211, and one end of the damping spring 33 away from the lower support 32 abuts against the top groove wall of the mounting groove 211. When the warp knitting machine generates vibration during operation, the upper support 21 transmits the vibration to the lower support 32 through the damping spring 33, and during the transmission process, the damping spring 33 buffers the longitudinal vibration.

[0032] A control plate 22 is disposed at the bottom of the upper support plate 2, and a sliding hole connected to the mounting groove 211 is formed at the top of the upper support 21, and the diameter of the sliding hole is the same as the diameter of the mounting groove 211. The control plate 22 can slide up and down in the sliding hole and the mounting groove 211, respectively, and the side walls of the control plate 22 are in sliding contact with the side walls of the mounting groove 211 and the side walls of the sliding hole, respectively, and the top of the damping spring 33 abuts against the bottom of the control plate 22.

[0033] A transmission groove 27 is formed in the upper support plate 2, and a transmission plate 23 is provided on the upper support plate 2. The transmission plate 23 slides up and down in the transmission groove 27. An elastic support member is provided in the upper support plate 2, and the elastic support member is a support spring 24. There are multiple support springs 24 and they are respectively provided in the transmission groove 27. The top of the support spring 24 abuts against the bottom of the transmission plate 23, and the bottom of the support spring 24 abuts against the bottom groove wall of the transmission groove 27. When the support spring 24 is elastically released, the transmission plate 23 is driven upward away from the lower support plate 3 to support the transmission plate 23.

[0034] The transmission plate 23 is provided with a counterweight ball 25, which is movably connected to the top of the transmission plate 23. When the warp knitting machine generates vibration during operation, the counterweight ball 25 bounces on the transmission plate 23, so that the gravitational potential energy generated by the bounce of the counterweight ball 25 pushes the transmission plate 23 to slide downward in the transmission groove 27. A friction strip 26 is embedded and fixed on the vertical side wall of the transmission groove 27, and the vertical side wall of the transmission plate 23 is in sliding contact with the friction strip 26. When the counterweight ball 25 bounces off the transmission plate 23 due to vibration, the friction strip 26 slides with the transmission plate 23 to generate friction, which slows down the speed of the transmission plate 23 moving upward, so that the vibration generated by the warp knitting machine maintains a fixed frequency, and when the counterweight ball 25 falls on the transmission plate 23 or is separated from the transmission plate 23, the transmission plate 23 can be maintained at a certain vertical height. When the vibration frequency generated by the warp knitting machine changes, the jumping frequency of the counterweight ball 25 adapts to the vibration frequency of the warp knitting machine, and at this time, the vertical height of the transmission plate 23 adapts to the jumping frequency of the counterweight ball 25.

[0035] The upper support plate 2 is provided with a control component. When the counterweight ball 25 vibrates and drives the transmission plate 23 to slide downward, the control component controls the control plate 22 to squeeze the vibration-damping spring 33, increases the elastic coefficient of the vibration-damping spring 33, and improves the buffering effect of the vibration-damping spring 33 on the warp knitting machine vibration; when the transmission plate 23 slides upward, the control component controls the control plate 22 to move away from the vibration-damping spring 33, reduces the elastic coefficient of the vibration-damping spring 33, and is beneficial to improving the service life of the vibration-damping spring 33.

[0036] See also Figure 4 and Figure 5 The control assembly includes a control shaft 61, a control worm wheel 62, a control worm 63, a control gear 64 and a control rack 6.

[0037] See also Figure 3 and Figure 5 The control rack 6 is fixedly connected to the bottom of the transmission plate 23, and the control rack 6 passes through the transmission groove 27 and slides up and down on the upper support plate 2. The control gear 64 is rotatably connected to the upper support plate 2, and the control rack 6 is meshed with the control gear 64. When the transmission plate 23 moves up and down, the control rack 6 drives the control gear 64 to rotate.

[0038] See also Figure 3 and Figure 4 The control shaft 61 is rotatably connected to the upper support plate 2. The control shaft 61 extends in the vertical direction and is inserted into the mounting groove 211. The bottom of the control shaft 61 is fixedly connected to the top of the control plate 22. The upper support plate 2 is fixedly connected with a limiting block. The outer peripheral side wall of the control shaft 61 is formed with a limiting groove extending in the vertical direction. The limiting block slides in the limiting groove to limit the rotation of the control shaft 61.

[0039] See also Figure 4 and Figure 5, the control worm wheel 62 is threadedly connected to the outer peripheral side of the control shaft 61, and the control worm wheel 62 is rotationally connected to the upper support plate 2. The control worm 63 is rotationally connected to the upper support plate 2, the control worm 63 extends in the horizontal direction and is perpendicular to the control shaft 61, the control worm 63 is meshed with the control worm wheel 62, and the control gear 64 is fixedly connected to the outer peripheral side of the control worm 63. When the transmission plate 23 moves downward, the control rack 6 drives the control worm 63 to rotate through the control gear 64, so that the control worm wheel 62 drives the control shaft 61 to rotate forward, thereby achieving the purpose of the transmission plate 23 moving downward and squeezing the shock-absorbing spring 33. When the transmission plate 23 moves upward, the control rack 6 drives the control worm 63 to rotate through the control gear 64, so that the control worm wheel 62 drives the control shaft 61 to rotate in the opposite direction, thereby achieving the purpose of the transmission plate 23 moving upward and away from the shock-absorbing spring 33 (the shock-absorbing spring 33 is in Figure 3 The purpose of marking in the middle).

[0040] See also Figure 5 and Figure 6 The vibration reduction device also includes a support block 4, which is fixed to the ground by screws. There are multiple support blocks 4 and they are evenly spaced along the circumferential direction with the lower pillar 32 as the center. A receiving groove 43 is formed in the support block 4, and a buffer ball 41 is provided in the support block 4. The buffer ball 41 corresponds to the receiving groove 43 one by one, and the buffer ball 41 is movably connected in the receiving groove 43. The support block 4 is provided with a buffer water bag 42, and the buffer water bag 42 is located in the receiving groove 43. The buffer water bag 42 is filled with water, and the buffer water bag 42 wraps the buffer ball 41. A diaphragm 421 is provided in the buffer water bag 42, and the diaphragm 421 is in a vertical state. The diaphragm 421 is fixedly connected to the inner peripheral side wall of the buffer water bag 42, so that the buffer water bag 42 forms a first buffer zone 422 and a second buffer zone 423, wherein the second buffer zone 423 is located on the side of the first buffer zone 422 away from the lower pillar 32. A plurality of communicating holes 4211 are formed on the diaphragm 421 , and the communicating holes 4211 are evenly spaced. The communicating holes 4211 communicate with the first buffer region 422 and the second buffer region 423 .

[0041] A movable opening 44 is formed at the top of the support block 4, and a buffer column 5 is fixedly connected to the buffer ball 41. The buffer column 5 passes through the movable opening 44 and protrudes out of the support block 4. The end of the buffer column 5 away from the support block 4 is hinged to the outer peripheral side wall of the upper support column 21 through a ball. A baffle 51 is provided on the outer peripheral side of the buffer column 5, and the baffle 51 is in sliding contact with the top groove wall of the accommodating groove 43. At the same time, a connecting ball 52 is fixedly connected to the outer peripheral side of the buffer column 5, and a rotating hole 511 is formed in the middle of the baffle 51. The connecting ball 52 is rotatably connected in the rotating hole 511, so that the buffer column 5 and the baffle 51 are connected by a ball hinge.

[0042] When the warp knitting machine generates lateral vibration, oblique vibration and other types of vibration, the upper support 21 transmits the vibration to the buffer ball 41 through the buffer column 5. When the buffer ball 41 receives the vibration, the buffer ball 41 squeezes the buffer water bag 42. According to different types of vibration, the water flow in the first buffer zone 422 is squeezed into the second buffer zone 423 through the connecting hole 4211, or the water flow in the second buffer zone 423 is squeezed into the first buffer zone 422 through the connecting hole 4211, so that the buffer water bag 42 absorbs the vibration from the buffer ball 41, thereby achieving the buffer column 5 to buffer the lateral vibration, oblique vibration and other types of vibration generated by the operation of the warp knitting machine.

[0043] The implementation principle of a vibration reduction device in the embodiment of the present application is: The warp knitting machine generates vibration when working, and then the vibration is transmitted to the upper support plate 21, and then the shock-absorbing spring 33 buffers the longitudinal vibration on the upper support 21. At the same time, the buffering water bag 42 buffers other types of vibrations such as lateral vibration and oblique vibration transmitted from the upper support 21 to the buffer column 5, thereby greatly improving the buffering effect of the vibration of the warp knitting machine.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
