Abstract

This invention relates to the field of damping and vibration reduction technology, specifically to an adjustable damping composite vibration reduction system for textile printing and dyeing equipment. The system includes a base plate and a top plate. A vibration reduction unit one and a movable plate are installed between the base plate and the top plate. A buffer spring one is fixedly connected between the top plate and the movable plate, and a vibration reduction unit two is installed between the movable plate and the base plate. During vibration reduction, the invention buffers vibration through the expansion and contraction of buffer spring one and buffer spring two. The up-and-down movement of piston rod one drives oil to flow in the return oil pipe. The friction between the oil and the return oil pipe dissipates vibration energy, suppressing machine vibration. By setting several return oil pipes of different lengths and using a switching mechanism to connect different return oil pipes to the oil storage chamber, the longer the return oil pipe, the greater the frictional resistance and the stronger the damping force as the oil passes through it.

Description

Technical Field

[0001] This invention relates to the field of damping and vibration reduction technology, specifically to an adjustable damping composite vibration reduction system for textile printing and dyeing equipment. Background Technology

[0002] Textile equipment (such as looms and spinning machines) are mostly high-speed machines with a large number of reciprocating moving parts (such as the reed of a loom and the roller of a spinning machine). During operation, they generate strong periodic vibrations. Vibrations can cause unstable yarn tension and fabric texture deviation, directly resulting in defects such as yarn breakage, skipped patterns, and uneven fabric surfaces, which seriously affect the product qualification rate. Therefore, textile printing and dyeing equipment needs to be vibration damping treated, which is a key link to ensure stable equipment operation, product quality, and production environment.

[0003] Existing textile printing and dyeing equipment generally uses spring-loaded vibration damping bases for vibration reduction. When the equipment vibrates, the springs absorb and dissipate vibration energy through elastic deformation. However, spring-loaded vibration damping bases can generally only dampen vibrations of textile printing and dyeing equipment with a single vibration intensity. Since textile equipment often needs to switch between different types (such as different yarn counts and fabric densities), the load and vibration frequency will change, resulting in a decrease in the damping effect of the spring-loaded vibration damping bases. In addition, when damping different types of textile printing and dyeing equipment, the vibration intensity will vary due to the different equipment types, further reducing the damping effect of existing spring-loaded vibration damping bases. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an adjustable damping composite vibration reduction system for textile printing and dyeing equipment, comprising a base plate and a top plate, wherein a vibration reduction unit I and a movable plate are installed between the base plate and the top plate, a buffer spring I is fixedly connected between the top plate and the movable plate, and a vibration reduction unit II is installed between the movable plate and the base plate.

[0005] The damping unit includes a damping cylinder fixedly installed on the top of the base plate and a piston rod slidably installed on the top of the damping cylinder. The top of the piston rod is fixedly connected to the bottom of the base plate. Several return oil pipes are evenly installed circumferentially on the inner wall of the outer wall of the damping cylinder. The length of the return oil pipes increases equally from small to large. An oil storage chamber is opened inside the damping cylinder and is located at the bottom of the return oil pipes and connected to them. A switching mechanism for switching between different return oil pipes and the oil storage chamber is also installed on the damping cylinder. An adjustment mechanism is installed between the oil storage chamber and the inner cavity of the damping cylinder.

[0006] In one possible implementation, the return oil pipes are distributed in an S-shape in the inner wall of the damping cylinder, and the length of several of the return oil pipes gradually increases in a clockwise direction, with the oil storage chamber located at the bottom of the inner cavity of the damping cylinder.

[0007] In one possible implementation, the switching mechanism includes a plurality of plugs slidably connected to a damping cylinder one along its radial direction and corresponding one-to-one with the return oil pipe one. The plugs are located between the return oil pipe and the oil storage chamber. Each plug has a through hole extending vertically through it. A return spring is fixedly connected between the side of the plug near the center of the damping cylinder one and the inner wall of the damping cylinder one. A toothed ring is rotatably mounted on the outer ring wall of the damping cylinder one. A push ring of the same height as the plugs is fixedly connected to the inner ring wall of the toothed ring. A trapezoidal groove is formed on the inner ring wall of the push ring. The end of the plug away from the center of the damping cylinder one slides against the inner ring wall of the push ring.

[0008] In one possible implementation, the adjusting mechanism includes a plurality of overflow holes circumferentially and evenly distributed inside the damping cylinder and located between the oil storage chamber and the inner cavity of the damping cylinder. The bottom and top of the overflow holes are respectively connected to the oil storage chamber and the inner cavity of the damping cylinder. A plurality of toothed blocks are rotatably mounted on the inner wall of the overflow hole near the center of the damping cylinder. The damping cylinder is also equipped with a swing assembly for driving the toothed blocks to rotate up and down.

[0009] In one possible implementation, the swing assembly includes a movable sleeve that is slidably mounted inside a damping cylinder. A plurality of racks are evenly mounted circumferentially on the outer ring wall of the movable sleeve. A transmission gear is fixedly connected to one side of each rack, and the transmission gear meshes with the corresponding rack. A servo cylinder for driving the movable sleeve to move up and down is fixedly mounted inside the damping cylinder. The bottom end of the telescopic shaft of the servo cylinder is fixedly connected to the bottom of the movable sleeve. The swing assembly also includes an accelerometer and a vibration analyzer fixedly mounted on the body of the textile printing and dyeing equipment. Both the accelerometer and the servo cylinder are electrically connected to the vibration analyzer.

[0010] In one possible implementation, the damping unit 2 includes a plurality of damping cylinders 2 fixedly installed on the top of the base plate and evenly distributed around the damping cylinder circumference. A piston rod 2 is slidably installed on the top of the damping cylinder 2. The top end of the piston rod 2 is fixedly connected to the bottom of the movable plate. A cover 1 located above the damping cylinder 2 is fixedly installed on the piston rod 2. A cover 2 and a lifting mechanism for driving the cover 2 to move up and down are movably installed on the outer ring wall of the damping cylinder 2. A buffer spring 2 sleeved on the outside of the damping cylinder 2 and the piston rod 2 is fixedly connected between the cover 1 and the cover 2.

[0011] In one possible implementation, the lifting mechanism includes a threaded sleeve threaded onto the outer annular wall of the second damping cylinder, the top of which is fixedly connected to the bottom of the second cover, and a rotating sleeve that is slidably mounted on the outer annular wall of the threaded sleeve via a spline, the bottom end of which extends below the threaded sleeve and is rotatably connected to the outer annular wall of the second damping cylinder.

[0012] In one possible implementation, a drive unit for driving the gear ring and the rotating sleeve to rotate is also installed on the base plate. The drive unit includes a drive gear ring rotatably mounted on the top of the base plate and coaxial with the damping cylinder. A driven gear one is fixedly installed on the outer ring wall of the rotating sleeve and meshes with the drive gear ring. A driven gear two is fixedly installed on the outer ring wall of the gear ring. A drive motor is fixedly installed on the outer ring wall of the damping cylinder. A driving gear located between the drive gear ring and the driven gear two is fixedly installed at the bottom of the output shaft of the drive motor. The front and rear sides of the driving gear mesh with the drive gear ring and the driven gear two, respectively.

[0013] In one possible implementation, the base plate is further equipped with a limiting mechanism for limiting the drive gear ring. The limiting mechanism includes limiting holes evenly spaced circumferentially on the outer ring wall of the drive gear ring. A fixing block is fixedly installed on the top of the base plate, and a screw is threadedly connected to the top of the fixing block. One end of the screw near the central axis of the damping cylinder is inserted into the corresponding limiting hole.

[0014] The beneficial effects of this invention are as follows: 1. During vibration damping, the piston rod 1 moves up and down due to vibration. The vibration is buffered by the expansion and contraction deformation of the buffer spring 1 and buffer spring 2. The up and down movement of the piston rod 1 pushes the oil to flow in the return oil pipe. The friction between the oil and the return oil pipe consumes the vibration energy and suppresses the vibration of the machine body. By setting several return oil pipes of different lengths, and using a switching mechanism to switch different return oil pipes to connect with the oil storage chamber, the longer the length of the return oil pipe, the greater the frictional resistance and the stronger the damping force when the oil passes through the return oil pipe. This makes it easier to install on textile printing and dyeing equipment with different vibration intensities for vibration damping and improves the applicability.

[0015] 2. During use, when the machine body vibrates, an accelerometer detects the acceleration generated by the vibration. The accelerometer outputs an electrical signal corresponding to the acceleration to a vibration analyzer. The vibration analyzer analyzes the intensity and frequency of the vibration based on the change in acceleration. Based on the intensity and frequency of the vibration, the vibration analyzer sends an electrical signal to the swing assembly in real time. The swing assembly controls the toothed block to rotate up and down. When the vibration intensity increases, the swing assembly controls the toothed block to rotate horizontally, thereby increasing the resistance of the oil flowing upward in the overflow hole and increasing the damping force. Conversely, when the vibration intensity decreases, the swing assembly controls the toothed block to rotate vertically, thereby reducing the resistance of the oil flowing in the overflow hole and reducing the damping force. By adjusting the magnitude of the damping force in real time, vibrations of different degrees can be accurately suppressed, improving the shock absorption effect.

[0016] 3. When the machine body vibrates, the piston rod one moves up and down with the vibration of the machine body. The buffer spring one provides primary shock absorption for the machine body. The vibration is transmitted through the buffer spring one, causing the movable plate to move up and down, which in turn causes the piston rod two to move up and down. The buffer spring two provides secondary shock absorption for the machine body, improving the shock absorption effect. The lifting mechanism pushes the cover two to move up and down, thereby changing the pre-compression of the buffer spring two and indirectly adjusting the trigger threshold of the damping force. This makes it easy to install on textile printing and dyeing equipment with different vibration intensities for shock absorption. Attached Figure Description

[0026] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Please see Figure 1 - Figure 8 A composite shock absorption system with adjustable damping for textile printing and dyeing equipment includes a base plate 1 and a top plate 3. A shock absorption unit 2 and a movable plate 5 are installed between the base plate 1 and the top plate 3. A buffer spring 4 is fixedly connected between the top plate 3 and the movable plate 5. A shock absorption unit 6 is installed between the movable plate 5 and the base plate 1.

[0028] The damping unit 2 includes a damping cylinder 21 fixedly installed on the top of the base plate 1 and a piston rod 22 slidably installed on the top of the damping cylinder 21. The top of the piston rod 22 is fixedly connected to the bottom of the top plate 3. Several return oil pipes 23 are evenly installed in the circumferential direction on the inner wall of the outer wall of the damping cylinder 21. The length of the return oil pipes 23 increases equally from small to large. An oil storage chamber 24 is opened inside the damping cylinder 21, located at the bottom of the return oil pipes 23 and connected to them. A switching mechanism 25 is also installed on the damping cylinder 21 for switching between different return oil pipes 23 and the oil storage chamber 24. An adjustment mechanism 26 is installed between the oil storage chamber 24 and the inner cavity of the damping cylinder 21.

[0029] In practical use, the top plate 3 is installed at the bottom of the textile printing and dyeing equipment body, and the bottom plate 1 is supported on the ground. When the machine body vibrates, the top plate 3 vibrates up and down with the machine body. At this time, the vibration is buffered by the expansion and contraction deformation of the buffer spring 4. The top plate 3 drives the piston rod 22 to move up and down together. The piston rod 22 drives the piston in the damping cylinder 21 to move up and down. The piston will push the oil to flow in the return oil pipe 23. The frictional resistance of the oil in the return oil pipe 23 consumes the vibration and suppresses the vibration of the machine body. When installed on textile printing and dyeing equipment with different vibration intensities, the switching mechanism 25 switches the return oil pipe 23 of different lengths to connect with the oil storage chamber 24, so that the oil flows from the return oil pipe 23 of different lengths. The longer the length of the return oil pipe 23, the greater the frictional resistance and the stronger the damping force when the oil passes through the return oil pipe 23, which makes it easier to install on textile printing and dyeing equipment with different vibration intensities for vibration reduction.

[0030] Please see Figure 1 - Figure 4The return oil pipes 23 are distributed in an S-shape in the inner wall of the damping cylinder 21. The length of several return oil pipes 23 gradually increases in the clockwise direction. The oil storage chamber 24 is located at the bottom of the inner cavity of the damping cylinder 21.

[0031] In practical use, by setting the return oil pipe 23 in an S-shape, the length of the return oil pipe 23 can be adjusted according to the spacing of the bending sections of the return oil pipe 23. The smaller the spacing of the bending sections of the return oil pipe 23, the more bending sections there are at the same height, and the longer the corresponding return oil pipe 23 is. The S-shape can increase the resistance to oil flow, improve the damping effect, and also reduce the space volume occupied by the return oil pipe 23.

[0032] Please see Figure 3 - Figure 6 The switching mechanism 25 includes several plugs 251 that are slidably connected to the damping cylinder 21 along its radial direction and correspond one-to-one with the return oil pipe 23. The plugs 251 are located between the return oil pipe 23 and the oil storage chamber 24. A through hole is provided on the plug 251. A return spring 252 is fixedly connected between the side of the plug 251 near the center of the damping cylinder 21 and the inner wall of the damping cylinder 21. A toothed ring 253 is rotatably installed on the outer ring wall of the damping cylinder 21. A push ring 254 of the same height as the plug 251 is fixedly connected to the inner ring wall of the toothed ring 253. A trapezoidal groove 255 is provided on the inner ring wall of the push ring 254. The end of the plug 251 away from the center of the damping cylinder 21 slides against the inner ring wall of the push ring 254.

[0033] In actual use, in the initial state, the trapezoidal groove 255 is aligned with one of the plugs 251. At this time, the rebound force of the return spring 252 pushes the corresponding plug 251 to move away from the center of the damping cylinder 21, so that the end of the plug 251 away from the central axis of the damping cylinder 21 slides into the trapezoidal groove 255. At this time, the through hole on the plug 251 is aligned vertically with the bottom end of the corresponding return oil pipe 23, so that the corresponding return oil pipe 23 is connected to the oil storage chamber 24. Meanwhile, the other plugs 251 are in contact with the push ring 254. The push ring 254 pushes the plug 251 back into the interior of the damping cylinder 21, so that the through hole on the plug 251 is misaligned with the return oil pipe 23, so that the other return oil pipes 23 are in a blocked state.

[0034] When switching the connection between other return oil pipes 23 and the oil storage chamber 24, the rotating toothed ring 253 drives the pushing ring 254 and the trapezoidal groove 255 to rotate. When the pushing ring 254 rotates, the inclined side of the trapezoidal groove 255 pushes the block 251 to move towards the central axis of the damping cylinder 21, so that the through hole on the block 251 is misaligned with the corresponding return oil pipe 23. When the trapezoidal groove 255 moves to the adjacent block 251, the end of the adjacent block 251 away from the central axis of the damping cylinder 21 slides into the trapezoidal groove 255, so that the adjacent return oil pipe 23 is connected to the oil storage chamber 24.

[0035] Please see Figure 2 - Figure 5 The adjusting mechanism 26 includes a plurality of overflow holes 261 that are circumferentially and evenly opened inside the damping cylinder 21 and located between the oil storage chamber 24 and the inner cavity of the damping cylinder 21. The bottom and top of the overflow holes 261 are respectively connected to the inner cavity of the oil storage chamber 24 and the inner cavity of the damping cylinder 21. A plurality of toothed blocks 262 that are equidistantly distributed vertically are rotatably installed on the inner wall of the overflow hole 261 near the center of the damping cylinder 21. The damping cylinder 21 is also equipped with a swing assembly 263 for driving the toothed blocks 262 to rotate vertically.

[0036] Please see Figure 2 - Figure 5 The swing assembly 263 includes a movable sleeve 2631 that is slidably installed inside the damping cylinder 21. Several racks 2632 are evenly installed circumferentially on the outer ring wall of the movable sleeve 2631. A transmission gear 2633 is fixedly connected to one side of the rack 262. The transmission gear 2633 meshes with the corresponding rack 2632. A servo electric cylinder 2634 for driving the movable sleeve 2631 to move up and down is fixedly installed inside the damping cylinder 21. The bottom end of the telescopic shaft of the servo electric cylinder 2634 is fixedly connected to the bottom of the movable sleeve 2631. The swing assembly 263 also includes an acceleration sensor 2635 and a vibration analyzer 2636 fixedly installed on the body of the textile printing and dyeing equipment. The acceleration sensor 2635 and the servo electric cylinder 2634 are both electrically connected to the vibration analyzer 2636.

[0037] In practical use, when piston rod 22 moves upward, the oil in oil storage chamber 24 flows upward through overflow hole 261 into the inner cavity of damping cylinder 21; conversely, the oil in the inner cavity of damping cylinder 21 flows into oil storage chamber 24 through overflow hole 261. When the machine body vibrates, acceleration sensor 2635 detects the acceleration generated by the vibration. Acceleration sensor 2635 outputs an electrical signal corresponding to the acceleration to vibration analyzer 2636. Vibration analyzer 2636 analyzes the intensity and frequency of vibration based on the change in acceleration. The intensity and frequency of vibration are transmitted to the oscillating component 263 in real time. The oscillating component 263 controls the toothed block 262 to rotate up and down. When the vibration intensity increases, the oscillating component 263 controls the toothed block 262 to rotate horizontally, thereby increasing the resistance of the oil flowing upward in the overflow hole 261 and increasing the damping force. Conversely, the oscillating component 263 controls the toothed block 262 to rotate vertically, thereby reducing the resistance of the oil flowing in the overflow hole 261 and reducing the damping force. By adjusting the magnitude of the damping force in real time, vibrations of different degrees can be accurately suppressed, thereby improving the vibration reduction effect.

[0038] Please see Figure 1 , Figure 3 , Figure 7 and Figure 8 The second damping unit 6 includes several damping cylinders 61 that are fixedly installed on the top of the base plate 1 and are evenly distributed around the first damping cylinder 21. A piston rod 62 is slidably installed on the top of the second damping cylinder 61. The top end of the piston rod 62 is fixedly connected to the bottom of the movable plate 5. A cover 63 located above the second damping cylinder 61 is fixedly installed on the piston rod 62. A cover 64 and a lifting mechanism 65 that drives the cover 64 to move up and down are movably installed on the outer ring wall of the second damping cylinder 61. A buffer spring 66 sleeved on the outside of the second damping cylinder 61 and the piston rod 62 is fixedly connected between the cover 63 and the cover 64.

[0039] Please see Figure 7 and Figure 8 The lifting mechanism 65 includes a threaded sleeve 651 threadedly mounted on the outer ring wall of the second damping cylinder 61. The top of the threaded sleeve 651 is fixedly connected to the bottom of the second cover 64. A rotating sleeve 652 is slidably mounted on the outer ring wall of the threaded sleeve 651 via a spline. The bottom end of the rotating sleeve 652 extends to the bottom of the threaded sleeve 651 and is rotatably connected to the outer ring wall of the second damping cylinder 61.

[0040] In practical use, rotating the rotating sleeve 652 causes the rotating sleeve 652 to rotate. When the threaded sleeve 651 rotates, it can move up or down along the damping cylinder 61. The threaded sleeve 651 drives the cover 64 to move up or down, thereby changing the pre-compression of the buffer spring 66 and indirectly adjusting the trigger threshold of the damping force. This makes it easy to install on textile printing and dyeing equipment with different vibration intensities for shock absorption.

[0041] When the machine vibrates, the top plate 3 moves up and down with the machine. At this time, the buffer spring 4 will expand and contract with the vibration. The expansion and contraction of the buffer spring 4 provides primary buffering for the vibration. The vibration is transmitted through the buffer spring 4, which drives the movable plate 5 and the piston rod 62 to move up and down together. At this time, the buffer spring 66 will expand and contract with the vibration. The expansion and contraction of the buffer spring 66 provides secondary buffering for the vibration. The damping force between the damping cylinder 61 and the piston rod 62 consumes the energy of the vibration and suppresses the vibration of the machine.

[0042] Please see Figure 7 and Figure 8 The base plate 1 is also equipped with a drive unit 7 for driving the gear ring 253 and the rotating sleeve 652 to rotate. The drive unit 7 includes a drive gear ring 71 rotatably mounted on the top of the base plate 1 and coaxial with the damping cylinder 21. A driven gear 72 is fixedly mounted on the outer ring wall of the rotating sleeve 652. The driven gear 72 meshes with the drive gear ring 71. A driven gear 73 is fixedly mounted on the outer ring wall of the gear ring 253. A drive motor 74 is fixedly mounted on the outer ring wall of the damping cylinder 21. A drive gear 75 is fixedly mounted at the bottom of the output shaft of the drive motor 74, located between the drive gear ring 71 and the driven gear 73. The front and rear sides of the drive gear 75 mesh with the drive gear ring 71 and the driven gear 73, respectively.

[0043] In practical use, the drive motor 74 drives the drive gear 75 to rotate, and the drive gear 75 drives the drive gear ring 71 and the driven gear 73 to rotate. The driven gear 73 drives the rotating sleeve 652 to rotate through the transmission of the driven gear 72, thereby realizing the up and down adjustment of the cover 64. At the same time, the driven gear 73 drives the gear ring 253 to rotate, thereby realizing the switching and adjustment of different return oil pipes 23.

[0044] Please see Figure 7 and Figure 8 The base plate 1 is also equipped with a limiting mechanism 76 for limiting the drive gear ring 71. The limiting mechanism 76 includes limiting holes 761 that are evenly opened in the circumferential direction on the outer ring wall of the drive gear ring 71. A fixing block 762 is fixedly installed on the top of the base plate 1. A screw 763 is threadedly connected to the top of the fixing block 762. One end of the screw 763 near the central axis of the damping cylinder 21 is inserted into the corresponding limiting hole 761.

[0045] In practical use, when the rotating sleeve 652 and the gear ring 253 are to be driven to rotate, the rotating screw 763 moves away from the central axis of the damping cylinder 21, so that the end of the screw 763 separates from the limiting hole 761, releasing the screw 763 from locking the drive gear ring 71. Then, the drive motor 74 is controlled to drive the drive gear 75 to rotate, so that the drive gear ring 71 rotates. The drive gear ring 71 rotates by a fixed angle each time. The limiting hole 761 can indicate the rotation angle of the drive gear ring 71, improving the adjustment accuracy. After the adjustment is completed, the screw 763 is rotated in the opposite direction to move closer to the central axis of the damping cylinder 21, so that the end of the screw 763 is reinserted into the limiting hole 761 to limit the drive gear ring 71 in real time, preventing the drive gear ring 71 from rotating during use.
