Description

Technical Field

[0001] The invention belongs to the technical field of textile equipment and relates to a textile rubber roller with shock-absorbing effect. Background Art

[0002] The rubber roller is a roll-shaped product made of metal or other materials as the core and rubber covered by vulcanization. The textile rubber roller made of polyurethane has lower wear than that made of nitrile rubber, has better rebound performance, and does not require grinding. It does not need to be coated before use, will not be entangled, and does not need grinding and repairing during use. It can reduce production costs and improve production efficiency for both manufacturers and users;

[0003] Textile rubber rollers can be used as traction rollers and guide rollers. They need to be installed on some textile equipment when in use. When the textile equipment is working, the vibration generated by the equipment operation will be transmitted to the textile rubber rollers. The vibration of the textile rubber rollers will intensify the friction between the textile products and the surface of the textile rubber rollers, accelerate the aging of the textile rubber rollers, and may cause the quality of the textile products to deteriorate. The existing textile rubber rollers can only achieve shock absorption through the elasticity of the rubber surface itself, and the shock absorption effect is poor.

[0004] Based on this, we designed a textile rubber roller with shock-absorbing effect. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems in the existing technology and propose a textile rubber roller with shock-absorbing effect. The technical problem to be solved by the device is: how to achieve the shock-absorbing effect of the textile rubber roller and reduce the influence of equipment vibration on the textile rubber roller.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A textile rubber roller with a shock-absorbing effect comprises a hollow roller body and two center shafts at both ends of the hollow roller body, two symmetrically distributed mounting plates are fixed inside the hollow roller body, a center rod is fixed at the middle position of the mounting plate, a universal joint coupling is connected between the center rod and the center shaft at the corresponding position, a limiting mechanism is provided between the center shaft and the mounting plate, two bearings are sleeved on the center shaft, a rotating ring is sleeved on the outer side of the two bearings, three circumferentially evenly distributed shock absorbers are provided on the outer side of the rotating ring, a rotating roller is provided at one end of the shock absorber away from the center shaft, the rotating roller is abutted against the inner wall of the hollow roller body, and a mounting mechanism for installing the rotating ring is provided on the rotating ring.

[0008] The working principle of the present invention is: when in use, the two center shafts are installed on the bearing seat of the equipment, and the limiting mechanism can keep the hollow roller body and the two center shafts in a horizontal state. When used as a guide roller, the shock absorber can provide displacement space for the hollow roller body to prevent the vibration transmission between the center shaft and the hollow roller body, and when the textile product generates lateral pressure on the hollow roller body, the length of the shock absorber will change. When the hollow roller body and the center shaft rotate, the rotating ring will stop rotating because the length of the shock absorber is different and the shock absorber has a damping effect and cannot change its length in time. When the roller is used as a traction roller, one of the central shafts can be connected to the motor shaft. Under the action of the universal joint coupling, the hollow roller body and the central shaft can still rotate along their respective axes even if they are eccentric, thus further reducing the vibration generated by the textile roller itself, thereby achieving the shock absorbing effect in many aspects.

[0009] The limiting mechanism includes a mounting seat fixed on the central axis, a plurality of straight rods evenly distributed around the circumference are fixed on the mounting seat, magnetic blocks are fixed at the ends of the straight rods, and shock-absorbing pads are provided at the ends of the magnetic blocks. A magnetic ring is embedded on one side of the mounting plate close to the central axis, and the magnetic ring and the magnetic block have the same magnetic poles relatively distributed.

[0010] With the above structure, when in use, the magnetic ring and the magnetic block are close to each other but not in contact, and a relatively stable repulsive force can be generated. When in use, the center axis is installed on the textile equipment, which can generate a large thrust on the mounting plate. The thrust of the center axis on the mounting plate at the corresponding position is all toward the center position of the hollow roller body, thereby balancing the thrust on both sides of the hollow roller body and preventing the hollow roller body from shifting to one end. In addition, the thrust generated by multiple magnetic blocks can further prevent the hollow roller body from tilting, so that it remains parallel to the center axis.

[0011] The shock absorbers are arranged on the outside of the rotating ring, one of which is fixed on the outside of the rotating ring and is the first shock absorber. Two symmetrically distributed sliding grooves are provided on the rotating ring, and the other two shock absorbers are slidably arranged in the sliding grooves at corresponding positions and are the second shock absorbers. An adjustment mechanism for adjusting the distance between the two second shock absorbers is provided between the two second shock absorbers.

[0012] With the above structure, when in use, the two second shock absorbers are oriented toward the force direction of the hollow roller body, and the two second shock absorbers provide supporting force for the hollow roller body. When the hollow roller body is subjected to greater pressure from the textile product, the two second shock absorbers can be moved closer to each other through the adjustment mechanism. At this time, the two second shock absorbers can provide greater supporting force, thereby reducing the offset distance of the hollow roller body, so that the device can be suitable for the production of more types of textile products with different tensioning force requirements, thereby expanding the scope of application of the device.

[0013] The adjusting mechanism comprises an arc-shaped rack fixed at the bottom of the second shock absorber, a rotating gear meshing with the arc-shaped rack is rotatably arranged on the rotating ring, and the rotating gear is located in the middle position of the two second shock absorbers, a cross bar is connected to the rotating ring, and a sliding hole is provided at one end of the cross bar, and an adjusting rod is slidably arranged in the sliding hole, a hand bolt is threadedly connected to the side end of the cross bar, and the end of the hand bolt is abutted against the side end of the adjusting rod, a protrusion is fixed to the side end of the adjusting rod, a socket is provided in the middle of the rotating gear, a spiral groove is provided on the inner wall of the socket, and the protrusion is slidably arranged in the spiral groove.

[0014] With the above structure, the lifting and lowering of the adjusting rod can drive the rotating gear to rotate through the protrusion and the spiral groove. When using the textile rubber roller and debugging, the operator can rotate the rotating gear according to the tensioning force of the textile product, and adjust the spacing of the two second shock absorbers to a suitable position through two arc-shaped racks, and then fix the adjusting rod by hand-tightening the bolts, thereby adjusting and fixing the positions of the two second shock absorbers.

[0015] A push rod is fixed to the end of the cross rod away from the adjusting rod, and a positioning hole is opened at the end of the push rod close to the rotating ring, a positioning rod is fixed to the outside of the rotating ring, and the positioning rod is slidably inserted in the positioning hole, a return spring is sleeved on the outside of the positioning rod, and the two ends of the return spring are respectively against the push rod and the rotating ring, an extrusion ring is fixed to the inner side of the hollow roller body, a bending rod is fixed on the rotating ring, and the two ends of the bending rod are fixed on the rotating ring, and the middle position of the bending rod passes over the outside of the cross rod.

[0016] With the above structure, when in use, the two second shock absorbers will be pushed apart to both sides and have a tendency to drive the rotating gear to rotate through the arc-shaped rack. The rotation of the rotating gear will push the outside of the adjusting rod. The bent rod can prevent the cross bar and the adjusting rod from moving outward, thereby preventing the two second shock absorbers from being squeezed and separated to both sides. Moreover, when the pressure of the textile product on the hollow roller body is relatively large, the hollow roller body will deviate greatly. At this time, the extrusion ring will squeeze the top rod. At this time, the cross bar and the adjusting rod will move toward the rotating ring and compress the reset spring. The movement of the adjusting rod will drive the rotating gear to rotate through the protrusion and the spiral groove. The rotating gear will further bring the two second shock absorbers closer to each other through the two arc-shaped racks, providing greater supporting force. The supporting force is automatically adjusted according to the real-time pressure on the hollow roller body, and the offset distance of the hollow roller body is reduced. It is more convenient to use and can further facilitate the operator to debug the equipment.

[0017] Two open clamps are fixed on the outer end of the shock absorber, and two annular grooves are arranged on the rotating roller, and the open clamps are clamped in the annular grooves.

[0018] With the above structure, when in use, the open clamp will press the rotating roller against the inner wall of the hollow roller body, the rotating roller will not fall off, and after removing the rotating ring, it is more convenient to replace the severely worn rotating roller.

[0019] The mounting mechanism includes an inner edge fixed to one side of a rotating ring, the rotating ring is provided with two symmetrically distributed square grooves, and a square block is arranged in the square groove, an elastic folding plate is fixed to the outer side of the rotating ring, and one end of the elastic folding plate is fixed to the outer side of the square block, hinged ears are arranged on both sides of the rotating ring, and a right-angle plate is rotatably connected to the hinged ear, and a handle is fixed to one end of the right-angle plate.

[0020] With the above structure, when installing the rotating ring, the inner side of the block is flush with the inner wall of the rotating ring, the rotating ring is put on the outside of the two bearings, and the inner edge is against the side end of the bearing, the two handles are pushed outward, and the right-angled plate is rotated. At this time, the right-angled side of one side of the right-angled plate will squeeze the block inward. At this time, the two sides of the block just against the outer rings of the two bearings, and the installation of the rotating ring can be achieved. Similarly, when disassembling, the right-angled plate can be pushed toward the middle, and the elastic folding plate will reset the block. At this time, the outer side of the rotating ring can be taken out, and disassembly is more convenient, and the rotating roller can be replaced more quickly.

[0021] A pull rod is fixed to the outer end of the shock absorber, and a pull pin is fixed to the end of the pull rod, two symmetrically distributed support rods are fixed to the outer side of the rotating ring, and a moving rod is slidably arranged on the support rod, a first inclined rod is fixed to one end of the moving rod, and the two first inclined rods are respectively located on the outer sides of the pull pins corresponding to the two second shock absorbers, the moving rod is located on the inner side of the right-angle plate at the corresponding position, and a second inclined rod is fixed to the other end of the moving rod, and the second inclined rod is located on the outer side of the pull pin corresponding to the first shock absorber.

[0022] With the above structure, when installing and disassembling the rotating ring, the operator can squeeze the right-angle plate toward the middle through the handle, so that the right-angle plate squeezes the moving rod, driving the first tilting rod and the second tilting rod to move, and the first tilting rod will compress the second shock absorber through the corresponding pull pin and pull rod, and the second tilting rod will compress the first shock absorber through the corresponding pull pin and pull rod, so that the rotating roller shrinks toward the middle. In this way, when moving the rotating ring, the rotating roller will not rub against the inner wall of the hollow roller body, and disassembly and installation are more convenient, and one person can perform disassembly and assembly.

[0023] Compared with the prior art, the textile rubber roller with shock absorption effect has the following advantages:

[0024] 1. Through the hollow roller body, center shaft, universal joint coupling and shock absorber, the shock absorber provides moving space for the displacement of the hollow roller body and maintains the supporting force of the hollow roller body. The universal joint coupling realizes the eccentric transmission of the hollow roller body and the center shaft, reduces the influence of equipment vibration on the hollow roller body, and reduces the vibration generated by the hollow roller body when it rotates, so as to achieve shock absorption effect in many aspects.

[0025] 2. The limiting mechanism balances the thrust on both sides of the hollow roller to prevent the hollow roller from deviating to one end. The thrust generated by multiple magnetic blocks can further prevent the hollow roller from tilting, keeping it parallel to the center axis, thereby ensuring the guiding and traction effect of the hollow roller.

[0026] 3. The distance between the two second shock absorbers is adjusted through the adjustment mechanism, which provides greater support force when the lateral pressure on the hollow roller is large, reduces the offset distance, and thus expands the application range of the device. In addition, it can be automatically adjusted in real time during use, making it more convenient to use.

[0027] 4. The rotating ring can be installed and disassembled through the installation mechanism, which is convenient for replacing a new rotating roller. During installation and disassembly, the rotating roller can be retracted to the middle to separate it from the inner wall of the hollow roller body. There will be no friction resistance during disassembly and installation, and one person can perform disassembly and assembly. BRIEF DESCRIPTION OF THE DRAWINGS

When the hollow roller body 1 and the center axis 2 rotate, the rotating ring 7 will stop rotating because the length of the shock absorber 8 is different and the shock absorber 8 has a damping effect and cannot change its length in time. At this time, the inner wall of the hollow roller body 1 and the rotating roller 9 roll relative to each other. The hollow roller body 1 can still rotate along its own axis when the force is offset, and the shock absorber 8 does not rotate, and its length remains unchanged, so that the vibration generated by the textile rubber roller itself is reduced when it rotates, achieving a shock absorbing effect. When used as a traction roller, one of the center axes 2 can be connected to the motor shaft. Under the action of the universal joint coupling 5, the hollow roller body 1 and the center axis 2 can still rotate along their respective axes even if they are eccentric, further reducing the vibration generated by the textile rubber roller itself, thereby achieving a shock absorbing effect in many aspects.

When in use, the central axis 2 is installed on the textile equipment, which can generate a large thrust on the mounting plate 3. The thrust of the central axis 2 on the mounting plate 3 at the corresponding position is all toward the center position of the hollow roller body 1, thereby balancing the thrust on both sides of the hollow roller body 1, preventing the hollow roller body 1 from deviating to one end, and the thrust generated by multiple magnetic blocks 603 together can further prevent the hollow roller body 1 from tilting, so that it remains parallel to the central axis 2.

At this time, the squeezing ring 1015 will squeeze the top rod 1010, and the cross bar 1003 and the adjusting rod 1005 will move toward the direction close to the rotating ring 7 and compress the reset spring 1013. The movement of the adjusting rod 1005 will drive the rotating gear 1002 to rotate through the protrusion 1007 and the spiral groove 1009, and the rotating gear 1002 will further move the two second shock absorbers 802 closer to each other through the two arc-shaped racks 1001, providing greater supporting force, and automatically adjusting the supporting force according to the real-time pressure on the hollow roller body 1, reducing the offset distance of the hollow roller body 1, making it more convenient to use and further facilitating the operator to debug the equipment.

[0050] The above fixing methods are the most commonly used fixing connection methods in this field, such as welding, bolt connection, etc.

[0051] Working principle of the present invention:

[0052] When in use, the two center shafts 2 are installed on the bearing seat of the equipment, and the magnetic ring 605 and the magnetic block 603 are close to each other but not in contact, which can generate a relatively stable repulsive force. When in use, the center shaft 2 is installed on the textile equipment, which can generate a large thrust on the mounting plate 3. The thrust of the center shaft 2 on the mounting plate 3 at the corresponding position is all toward the center position of the hollow roller body 1, thereby balancing the thrust on both sides of the hollow roller body 1 and preventing the hollow roller body 1 from deviating to one end. In addition, the thrust generated by multiple magnetic blocks 603 together can further prevent the hollow roller body 1 from tilting, so that it remains parallel to the center shaft 2. When in use, the two The second shock absorbers 802 face the force direction of the hollow roller body 1, and the two second shock absorbers 802 provide support force for the hollow roller body 1. When the hollow roller body 1 is subjected to a large pressure from the textile product, the hollow roller body 1 will deviate greatly. At this time, the extrusion ring 1015 will squeeze the top rod 1010. At this time, the cross bar 1003 and the adjustment rod 1005 will move in the direction close to the rotating ring 7 and compress the reset spring 1013. The movement of the adjustment rod 1005 will drive the rotating gear 1002 to rotate through the protrusion 1007 and the spiral groove 1009, and the rotating gear 1002 will further rotate through the two arc-shaped racks 1001 brings the two second shock absorbers 802 closer to each other to provide greater supporting force, automatically adjusts the supporting force according to the real-time pressure on the hollow roller body 1, reduces the offset distance of the hollow roller body 1, is more convenient to use, and can further facilitate the operator to debug the equipment. The shock absorber 8 can prevent the vibration transmission between the central axis 2 and the hollow roller body 1, and when the textile product generates lateral pressure on the hollow roller body 1, the length of the shock absorber 8 will change. When the hollow roller body 1 and the central axis 2 rotate, the rotating ring 7 will change in time because of the different lengths of the shock absorber 8 and the damping effect of the shock absorber 8. The length of the hollow roller body 1 stops rotating, at this time the inner wall of the hollow roller body 1 and the rotating roller 9 roll relative to each other, the hollow roller body 1 can still rotate along its own axis when subjected to force displacement, and the shock absorber 8 does not rotate, and its length remains unchanged, so that the vibration generated by the textile rubber roller itself during rotation is reduced, thereby achieving a shock absorbing effect. When used as a traction roller, one of the central shafts 2 can be connected to the motor shaft. Under the action of the universal joint coupling 5, the hollow roller body 1 and the central shaft 2 can still rotate along their respective axes even if they are eccentric, thereby further reducing the vibration generated by the textile rubber roller itself, thereby achieving a shock absorbing effect in many aspects.

[0053] In addition, when installing the rotating ring 7, the inner side of the block 1301 is flush with the inner wall of the rotating ring 7, the rotating ring 7 is put on the outside of the two bearings, and the inner edge 702 is against the side end of the bearing, the two handles 1304 are pushed outward, and the right-angled plate 1303 is rotated. At this time, the right-angled side of the right-angled plate 1303 will squeeze the block 1301 inward. At this time, the two sides of the block 1301 just against the outer rings of the two bearings, and the installation of the rotating ring 7 can be achieved. Similarly, when disassembling, the right-angled plate 1303 can be pushed toward the middle, and the elastic folding plate 1302 will reset the block 1301. At this time, the outer side of the rotating ring 7 can be taken out, and the disassembly is more convenient, and the replacement of the rotating roller 9 can be carried out more quickly.

[0054] Moreover, when installing and disassembling the rotating ring 7, the operator can use the handle 1304 to squeeze the right-angle plate 1303 toward the middle, so that the right-angle plate 1303 squeezes the moving rod 1307, driving the first tilting rod 1308 and the second tilting rod 1309 to move, and the first tilting rod 1308 will compress the second shock absorber 802 through the corresponding pull pin 1306 and the pull rod 1305, and the second tilting rod 1309 will compress the first shock absorber 801 through the corresponding pull pin 1306 and the pull rod 1305, so that the rotating roller 9 shrinks toward the middle, so that when moving the rotating ring 7, the rotating roller 9 will not rub against the inner wall of the hollow roller body 1, and the disassembly and installation are more convenient, and one person can perform the disassembly and installation.

[0055] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
