Description

Technical Field

[0001] The invention relates to the field of equipment shock absorption, and in particular to a shock absorption device for textile equipment. Background Art

[0002] In the field of textile industry, the stable operation of textile equipment is crucial to product quality and production efficiency. However, during the high-speed operation of textile equipment, the equipment legs will produce obvious up and down vibrations. This vibration will not only affect the processing accuracy of textile equipment, but also cause defects in textiles and reduce product quality.

[0003] Traditional shock absorption solutions for textile equipment mostly adopt a relatively basic configuration, which is to simply combine rubber pads with spring shock absorbers to suppress the vibration generated during the operation of the equipment.

[0004] However, during long-term uninterrupted operation, textile equipment will continue to produce strong and frequent vibrations. The load formed by these vibrations acts on the spring of the spring shock absorber for a long time. As time goes by, the spring will inevitably experience fatigue deformation. Once the spring is fatigued and deformed, its originally good elasticity will gradually decline, which will lead to a gradual decrease in the shock absorption performance of the entire spring shock absorber. Summary of the invention

[0005] In order to overcome the disadvantage that the spring of a spring shock absorber is prone to fatigue deformation when subjected to vibration load for a long time, resulting in a gradual decrease in shock absorption performance, the present invention provides a shock absorbing device for textile equipment that can increase the force applied to the spring of the spring shock absorber according to the vibration amplitude of the textile equipment, thereby suppressing the textile equipment according to the vibration amplitude in real time, thereby reducing the vibration amplitude of the textile equipment and improving the processing quality of the textile equipment.

[0006] The technical solution is: a shock absorbing device for textile equipment, including a base plate, which is divided into two. Buffer pads are fixedly installed on the two base plates, and textile equipment feet are placed between the two buffer pads. Mounting plates are fixedly connected on both sides of each base plate, and a friction shock absorbing mechanism is fixedly connected to the upper part of each mounting plate. A torque limiting mechanism is provided on the friction shock absorbing mechanism, and a friction wheel is provided on the friction shock absorbing mechanism.

[0007] As a further preferred embodiment, the friction shock absorbing mechanism includes a fixed seat, each mounting plate is fixedly connected to a fixed seat on the upper part, each fixed seat is fixedly connected to a protective shell, each mounting plate is slidably connected to an extrusion seat, each extrusion seat is also slidably connected to a movable seat, a telescopic spring is fixedly connected between the extrusion seat and the movable seat on the same side, each movable seat is fixedly connected to an octagonal block on both sides, and a friction wheel is rotatably connected between the two octagonal blocks of each movable seat.

[0008] As a further preferred solution, the torque limiting mechanism includes a pressure seat, each movable seat is slidably connected to a pressure seat on both sides, each pressure seat is fixedly connected to a fixed column on the upper and lower sides, and a torsion spring is fixedly connected between the two pressure seats on both sides of the friction wheel.

[0009] As a further preferred scheme, it also includes a swing mechanism, which is arranged on a mounting plate, and is used to detect the vibration frequency of the textile equipment support foot. The swing mechanism includes a fixed bracket, and each mounting plate is fixedly connected to a fixed bracket on both sides, and each fixed bracket is fixedly connected to a fixing bolt, and four fixing bolts are rotatably connected to a swing slot rod, and a sliding groove is provided on the swing slot rod, and both sides of the two ends of the textile equipment support foot are fixedly connected to a fixed round seat, and each fixed round seat is respectively located in the sliding groove of the swing slot rod on the same side, and each fixed bracket is rotatably connected to a rotating rod, and a large gear is fixedly connected to the rotating rod above each fixed bracket, and a small gear is fixedly connected to the rotating rod below each fixed bracket, and an outer arc-shaped rack is fixedly connected to the upper side of each swing slot rod, and an inner arc-shaped rack is fixedly connected to the lower side of each swing slot rod.

[0010] As a further preferred scheme, it also includes a pressure-damping mechanism, which is arranged on a fixed bracket and is used to apply pressure to the movable seat. The pressure-damping mechanism includes a transmission rod, and a transmission rod is rotatably connected between two fixed brackets on both sides of the fixed seat. Overrunning clutches are fixedly connected on both sides of the transmission rod, and pulleys are fixedly connected on the two overrunning clutches and four rotating rods. A belt is wound around the three pulleys on the same side, a cam is fixedly connected to the middle part of the transmission rod, and a fixed push rod is fixedly connected between two extrusion seats on the same fixed seat, and the inner side of the fixed push rod is in contact with the cam.

[0011] As a further preferred solution, the fixed push rod has a trapezoidal structure.

[0012] As a further preferred scheme, it also includes a relative clamping mechanism, which is arranged on a movable seat and is used to clamp the friction wheel.

[0013] Compared with the prior art, the present invention has the following advantages: 1. The eight friction wheels respectively drive the two octagonal blocks and the movable seat to squeeze the telescopic springs. The eight telescopic springs are all in a compressed state, so that the eight friction wheels are tightly fitted with the textile equipment feet. Under the joint action of sixteen torsion springs, the rotation resistance of the eight friction wheels is greatly increased. This resistance is transmitted to the textile equipment feet through the eight friction wheels, increasing the friction between the two, thereby effectively suppressing the up and down vibration of the textile equipment feet.

[0014] 2. The elastic force generated by the compression of the telescopic spring pushes the moving seat, the octagonal block and the friction wheel, so that each friction wheel fits more closely with the support foot of the textile equipment. In this way, the friction between the friction wheel and the support foot of the textile equipment is further increased, and the squeezing effect of the friction wheel on the vibration of the support foot of the textile equipment is further enhanced.

[0015] 3. The upper and lower sides of the extrusion plate squeeze the two fixed columns on each pressure seat respectively. The movement of the fixed push rod will synchronously drive the curved round rod and the extrusion plate to apply pressure to the pressure seat, further compressing the torsion spring. In this way, the force between the pressure seat and the friction wheel is increased. The textile equipment support foot needs to overcome greater friction to drive the friction wheel to rotate.

[0024] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Embodiment 1: A shock absorbing device for textile equipment, such as Figure 1-Figure 3 As shown, it includes a base plate 1, which is divided into two. Buffer pads 2 are fixedly installed on the two base plates 1, and textile equipment legs 3 are placed between the two buffer pads 2. Mounting plates 4 are welded on both sides of each base plate 1, and a friction shock absorbing mechanism is provided on the upper part of each mounting plate 4. A torque limiting mechanism is provided on the friction shock absorbing mechanism. The friction shock absorbing mechanism is used to squeeze the textile equipment legs 3 to suppress vibration. A friction wheel 57 is provided on the friction shock absorbing mechanism, and the torque limiting mechanism is used to limit the friction wheel 57.

[0026] The friction damping mechanism includes a fixed seat 51, a fixed seat 51 is welded on the upper part of each mounting plate 4, a protective shell 52 is welded on each fixed seat 51, an extrusion seat 54 is slidably connected to each mounting plate 4, a moving seat 53 is also slidably connected to each extrusion seat 54, a telescopic spring 55 is fixedly connected between the extrusion seat 54 and the moving seat 53 on the same side, an octagonal block 56 is welded on both sides of each moving seat 53, a friction wheel 57 is rotatably connected between the two octagonal blocks 56 of each moving seat 53, and the friction wheel 57 is used to squeeze the textile equipment support foot 3.

[0027] The torque limiting mechanism includes a pressure seat 61. Both sides of each movable seat 53 are slidably connected to a pressure seat 61. Fixed columns 62 are welded on the upper and lower sides of each pressure seat 61. Torsion springs 63 are fixedly connected between the two pressure seats 61 on both sides of the friction wheel 57.

[0028] At first, the eight squeezing seats 54 are limited by the mounting plate 4, and the textile equipment support foot 3 squeezes the eight friction wheels 57 respectively. The eight friction wheels 57 respectively drive the two octagonal blocks 56 and the moving seat 53 to squeeze the telescopic spring 55. The eight telescopic springs 55 are all in a compressed state, so that the eight friction wheels 57 are tightly fitted with the textile equipment support foot 3. At the same time, under the action of the eight pressure seats 61, the sixteen torsion springs 63 respectively press on the two sides of the four friction wheels 57. When the equipment on the textile equipment support foot 3 is working, the textile equipment support foot 3 will vibrate. When the textile equipment support foot 3 vibrates up and down, the buffer pad 2 effectively reduces the vibration of the textile equipment support foot 3 by virtue of its own elasticity. When the foot 3 vibrates up and down, under the limiting action of the octagonal block 56, every two pressure seats 61 apply resistance to one of the friction wheels 57 through the torsion spring 63. The textile equipment foot 3 and the eight friction wheels 57 generate friction to drive the eight friction wheels 57 to rotate, but each friction wheel 57 is respectively limited by two torsion springs 63. Under the joint action of sixteen torsion springs 63, the rotation resistance of the eight friction wheels 57 is greatly increased. This resistance is transmitted to the textile equipment foot 3 through the eight friction wheels 57, increasing the friction between the two, thereby effectively suppressing the up and down vibration of the textile equipment foot 3. After stopping the textile equipment, the textile equipment no longer drives the textile equipment foot 3 to vibrate.

[0029] Embodiment 2: Based on embodiment 1, Figure 4-Figure 6 As shown, it also includes a swing mechanism, which is arranged on the mounting plate 4. The swing mechanism is used to detect the vibration frequency of the textile equipment support foot 3. The swing mechanism includes a fixed bracket 71, and fixed brackets 71 are welded on both sides of each mounting plate 4. A fixing bolt 701 is welded on each fixed bracket 71. The four fixing bolts 701 are rotatably connected with a swing slot rod 72, and a sliding groove is opened on the swing slot rod 72. Fixed round seats 73 are fixedly connected on both sides of both ends of the textile equipment support foot 3. Each fixed round seat 73 is respectively located in the sliding groove of the swing slot rod 72 on the same side. Each fixed bracket 71 is rotatably connected with a rotating rod 74, and a large gear 75 is fixedly connected to the rotating rod 74 above each fixed bracket 71, and a small gear 76 is fixedly connected to the rotating rod 74 below each fixed bracket 71. The upper side of each swing slot rod 72 is fixedly connected with an outer arc rack 77, and the lower side of each swing slot rod 72 is fixedly connected with an inner arc rack 78.

[0030] It also includes a pressure-damping mechanism, which is arranged on the fixed bracket 71 and is used to apply pressure to the movable seat 53. The pressure-damping mechanism includes a transmission rod 81. The transmission rod 81 is rotatably connected between the two fixed brackets 71 on both sides of the fixed seat 51. Overrunning clutches 82 are fixedly connected on both sides of the transmission rod 81. Pulleys 83 are fixedly connected on the two overrunning clutches 82 and the four rotating rods 74. A belt 84 is wound around the three pulleys 83 on the same side. A cam 85 is fixedly connected to the middle of the transmission rod 81. A fixed push rod 86 is welded between the two extrusion seats 54 on the same fixed seat 51. The fixed push rod 86 has a trapezoidal structure, and the inner side of the fixed push rod 86 contacts the cam 85.

[0031] At first, the sliding groove of each swinging slot rod 72 is respectively stuck in the fixed round seat 73, and the textile equipment support foot 3 vibrates up and down to drive the four fixed round seats 73 to vibrate together, and the four fixed round seats 73 respectively drive the four swinging slot rods 72 to swing, and each swinging slot rod 72 drives the outer arc rack 77 and the inner arc rack 78 to swing respectively. When the textile equipment support foot 3 drives the fixed slot rod to swing upward, the outer arc rack 77 on the fixed slot rod also swings, and the outer arc rack 77 drives one of the rotating rods 74, one of the pulleys 83 and the large gear 75 to reverse, and one of the pulleys 83 drives another pulley 83, the transmission rod 81, the overrunning clutch 82 on the transmission rod 81 and the belt on the overrunning clutch 82 through the belt 84. The wheels 83 are reversed together, and the reverse rotation of each transmission rod 81 drives the cam 85 to reverse together. The reverse rotation of each cam 85 squeezes the fixed push rod 86 to move in the direction of the friction wheel 57. Each fixed push rod 86 drives the two extrusion seats 54 to move in the direction of the friction wheel 57. Each extrusion seat 54 applies force to the telescopic spring 55 to compress it. The elastic force generated by the compression of the telescopic spring 55 pushes the moving seat 53, the octagonal block 56 and the friction wheel 57, so that each friction wheel 57 is more closely fitted with the textile equipment support foot 3. In this way, the friction between the friction wheel 57 and the textile equipment support foot 3 is further increased, and the extrusion effect of the friction wheel 57 on the vibration of the textile equipment support foot 3 is further enhanced. When the swing slot rod 72 is When resetting upward and downward, the outer arc-shaped rack 77 drives the large gear 75, one of the rotating rods 74 and one of the pulleys 83 to reset. The reset of one of the pulleys 83 drives the other rotating rod 74, the pulley 83 on the other rotating rod 74 and the pulley 83 on the overrunning clutch 82 to reset through the belt 84. Under the action of the overrunning clutch 82, the positive rotation of the pulley 83 on the overrunning clutch 82 will not drive the transmission rod 81 and the cam 85 on the transmission rod 81 to rotate forward. When the textile equipment support foot 3 drives the fixed groove rod to swing downward, the fixed groove rod drives the inner arc-shaped rack 78 to swing together, and the inner arc-shaped rack 78 drives the small gear 76 to reverse. The reversal of the small gear 76 drives the other rotating rod 74 and the other pulley 83 to reverse together , the other pulley 83 reverses and drives one of the pulleys 83, the transmission rod 81 and the pulley 83 on the overrunning clutch 82 to reverse together through the belt 84, and the transmission rod 81 drives the cam 85 to reverse together. When the swing groove rod 72 is reset from bottom to top, the inner arc rack 78 drives the pinion 76 to reset, and the reset of the pinion 76 drives the other rotating rod 74 and the other pulley 83 to reset together. The reset of the other pulley 83 drives one of the pulleys 83 and the pulley 83 on the overrunning clutch 82 to reset together through the belt 84. Under the action of the overrunning clutch 82, the transmission rod 81 and the cam 85 will not reset, and the swing groove rod 72, the outer arc rack 77 and the inner arc rack 78 are driven to swing through the vibration of the textile equipment support foot 3.Then, the swing amplitude of the outer arc-shaped rack 77 drives the swing amplitude of the large gear 75 or the inner arc-shaped rack 78 to drive the small gear 76 to mesh, and then the vibration amplitude of the textile equipment support foot 3 can be converted into the rotation amplitude of the large gear 75 or the small gear 76. The rotation amplitude of the large gear 75 or the small gear 76 can increase the force applied to the friction wheel 57 in real time, and then further suppress the vibration of the textile equipment support foot 3. When the textile equipment stops running, the textile equipment support foot 3 stops vibrating, and the textile equipment support foot 3 no longer drives the swing slot rod 72 to swing through the fixed round seat 73.

[0032] Embodiment 3: Based on embodiment 2, Figure 7 As shown, it also includes a clamping mechanism facing each other, which is arranged on the movable seat 53 and is used to clamp the friction wheel 57. The clamping mechanism facing each other includes a support 91. Supports 91 are welded on both sides of each movable seat 53. A curved round rod 92 is slidably connected between the two supports 91 on one side. Extrusion plates 93 are welded on both ends of each curved round rod 92. Both sides of each extrusion plate 93 are respectively in contact with two fixed columns 62 on the pressure seat 61.

[0033] When each fixed push rod 86 moves toward the friction wheel 57, the upper and lower ends of the fixed push rod 86 push the curved round rod 92, making it move synchronously along the support 91, and the two ends of the curved round rod 92 drive the extrusion plate 93 to move together, and the upper and lower sides of the extrusion plate 93 respectively squeeze the two fixed columns 62 on each pressure seat 61. The movement of the fixed push rod 86 will synchronously drive the curved round rod 92 and the extrusion plate 93 to apply pressure to the pressure seat 61, further compressing the torsion spring 63. In this way, the acting force between the pressure seat 61 and the friction wheel 57 increases. The textile equipment support foot 3 needs to overcome a greater friction force to drive the friction wheel 57 to rotate. When the fixed push rod 86 no longer pushes the curved round rod 92, under the elastic action of the torsion spring 63, the pressure seat 61 is always in contact with the octagonal block 56, and the two fixed columns 62 on the pressure seat 61 push the extrusion plate 93.

[0034] The technical principles of the embodiments of the present invention are described above in conjunction with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present invention and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present invention. Based on the explanations herein, those skilled in the art can think of other specific implementation methods of the embodiments of the present invention without creative work, and these methods will fall within the protection scope of the embodiments of the present invention.
