Description

Technical Field

[0001] The invention belongs to the technical field of textile equipment and relates to a textile rubber roller for spun yarn with a shiftable contact position. 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] After searching, it is found that a split textile rubber roller that can be adjusted laterally is disclosed in Chinese patent literature [Application No.: CN202322428756.3; Publication No.: CN220827511U]. This split textile rubber roller that can be adjusted laterally includes a shaft body, a roller body and a positioning nut. The roller body is sleeved on the shaft body and is detachably connected thereto. The roller body is locked on the shaft body by a positioning nut. The positioning nut is located on the left side of the roller body and is threadedly connected to the shaft body. The shaft body is provided with a shaft body spiral groove track, and the inner side of the roller body is provided with a lining bayonet that matches the shaft body spiral groove track. Although the textile rubber roller is set as a split structure, the roller body can be adjusted laterally on the shaft body, and the worn position can be avoided by lateral adjustment, thereby extending the service life of the rubber roller. However, when adjusting, the rubber roller needs to be removed as a whole to adjust the position of the roller body, which requires the equipment to be shut down, reducing production efficiency.

[0004] Based on this, we designed a textile rubber roller for spun yarn with a shiftable contact position. Summary of the invention

[0005] The purpose of the present invention is to address the above-mentioned problems in the prior art and to propose a textile rubber roller for spun yarn with a shiftable contact position. The technical problem to be solved by the device is: how to adjust the lateral position of the textile rubber roller without stopping the machine so that the yarn avoids the worn parts and improves production efficiency.

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

[0007] A textile rubber roller for spun yarn with a shiftable contact position, comprising a fixed tube with both ends fixed on a mounting seat and a hollow roller body arranged outside the fixed tube, two symmetrically distributed adjusting mechanisms are arranged inside the fixed tube, and a rotating sleeve is rotatably arranged outside the adjusting mechanism, the inner side of the hollow roller body is fixedly connected to the two rotating sleeves, two symmetrically distributed supporting rollers are arranged on both sides of the hollow roller body, and supporting mechanisms for changing the positions of the supporting rollers are arranged at both ends of the supporting rollers, and a plurality of annular grooves for limiting the lateral deviation of the spun yarn are opened on the supporting rollers.

[0008] The working principle of the present invention is as follows: when in use, the yarn passes around the hollow roller body, the supporting roller is located at the edge of the yarn and the yarn passes through the annular groove at the corresponding position on the supporting roller, at which time the annular groove can prevent the yarn from being laterally offset, and when the position where the hollow roller body contacts the yarn is aged and worn, the two supporting rollers can first be moved closer to the middle through the supporting mechanism to support the yarn and separate it from the hollow roller body, and at this time the two rotating sleeves can be moved to one side through the two adjusting mechanisms at the same time, and the rotating sleeves will drive the hollow roller body to move to one end, separating the aging position from the yarn position, and then the two supporting rollers are reset to make the yarn contact with the hollow roller body, so that all parts of the hollow roller body can be fully utilized to reduce costs, and the hollow roller body can be moved without stopping the machine, thereby ensuring continuous production of yarn and improving production efficiency.

[0009] The rotating sleeve comprises an annular sleeve, a fixed convex edge is fixed on the outer side of the annular sleeve, and a plurality of notched grooves and a plurality of threaded mounting holes distributed at equal intervals are provided on the fixed convex edge, and a plurality of first connecting ears and a plurality of second connecting ears are fixed on the inner side of the hollow roller body, and the first connecting ears and the second connecting ears are both provided with connecting holes.

[0010] With the above structure, the first connecting ear and the second connecting ear are respectively located on the outside of the two fixed flanges, and are fixed to the fixed flanges by bolts and threaded mounting holes at corresponding positions. The operator can remove the bolts from both ends, and the first connecting ear and the second connecting ear can both pass through the notch groove, so that the hollow roller body can be moved out from the end of the fixed tube, which is convenient for replacing the hollow roller body.

[0011] The adjusting mechanism comprises two bearing seats fixed inside the fixed tube, an adjusting threaded rod is rotatably arranged between the two bearing seats, and the outer side of the adjusting threaded rod is threadably connected with a movable sleeve, a plurality of circumferentially evenly distributed sliding blocks are fixed to the outer side of the movable sleeve, a plurality of circumferentially evenly distributed sliding grooves are opened on the side wall of the fixed tube, and the sliding blocks are slidably arranged in the sliding grooves at corresponding positions, and a rotating bearing is sleeved on the outer side of the sliding block, and an annular sleeve is sleeved on the outer side of the rotating bearing, a vertical plate is fixed to the end of the adjusting threaded rod located on the outer side of the fixed tube, a rocker is rotatably arranged on the end of the vertical plate away from the adjusting threaded rod, and a clamp for clamping the rocker is fixed on the vertical plate.

[0012] When the operator turns the adjusting threaded rod in one of the adjusting mechanisms, the adjusting threaded rod in the other adjusting mechanism will lock the movable sleeve, the annular sleeve and the hollow roller body, so as to prevent the operator from accidentally touching the rocker and the vertical plate to drive the hollow roller body to move laterally and cause the yarn to break, thereby playing a safety role.

[0013] A long groove is provided on the outer side of the slider, and a moving block is slidably arranged in the long groove, and a rotating bearing sleeve is arranged on the outer side of the moving block. Circular holes are provided at both ends of the moving block, and a return spring is arranged in the circular hole, and one end of the return spring located on the outer side of the circular hole abuts against the inner wall of one end of the long groove.

[0014] With the above structure, since the two adjustment mechanisms need to be adjusted synchronously to produce an effect on the lateral movement of the hollow roller body, it is difficult for the two operators to rotate the adjustment threaded rods synchronously at all times. In actual use, when the two operators respectively rotate the adjustment threaded rods in the two adjustment mechanisms and a synchronization error occurs, the movable sleeve can still move slightly without affecting the hollow roller body. At this time, the position of the movable block in the long groove changes, so that the two adjustment threaded rods can be slightly out of sync, thereby improving the operator's operation fluency and facilitating the operator's operation.

[0015] The bottom of the moving block is provided with a first bayonet, and the middle position of the bottom of the long slot is provided with a second bayonet, and a limiting magnetic block is arranged in one of the first bayonet and the second bayonet at the corresponding position of the first bayonet, one end of the adjusting threaded rod is provided with a first long hole, and the other end is provided with a second long hole, and the first long hole is connected to the second long hole, a long rod is slidably arranged in the first long hole, an annular magnetic sleeve is sleeved on the outer side of the long rod, an inner hole is provided at one end of the long rod close to the second long hole, and a spiral groove is arranged on the outer side of the inner hole, a fixing rod is slidably arranged in the second long hole, and a fixing seat is fixed at one end of the fixing rod located at the outer side of the second long hole, the fixing seat is fixed on the inner wall of the fixing tube, a fixing pin is fixed on the other end of the fixing rod, and the fixing pin is slidably arranged in the spiral groove, a thrust spring is sleeved on the fixing rod, and two ends of the thrust spring are respectively abutted against the end of the long rod and the bottom wall of the first long hole, a push rod is fixed on the rocker, and the push rod abuts against one end of the long rod away from the thrust spring.

[0016] With the above structure, the push rod squeezes the long rod inward and compresses the thrust spring, and at this time the annular magnetic sleeve and the limiting magnetic block have the same magnetic poles approach each other, and under the action of repulsion, the limiting magnetic block abuts against the first bayonet, so that there will be no relative sliding between the moving block and the moving sleeve, and then the moving sleeve will not move when the operator accidentally touches one of the vertical plates and the rocker, and the position of the hollow roller body on the outside is further restricted. When the rocker pulls out the clamp, the push rod no longer abuts against the long rod, and at this time, under the action of the thrust spring, the long rod moves outward, and under the action of the fixing pin and the spiral groove, the long rod rotates, and the magnetic pole of the annular magnetic sleeve reverses, generating suction on the limiting magnetic block, so that the limiting magnetic block disengages from the first bayonet, and when the operator rotates the two adjusting threaded rods, a small degree of asynchronism can be allowed, thereby improving the smoothness of operation.

[0017] The supporting mechanism includes a fixed ring fixedly arranged at the end of the fixed tube and two rotating rings rotatably arranged at the end of the fixed tube, and an extension rod is fixed on the rotating ring, and the end of the extension rod is rotatably connected to the end of the supporting roller at the corresponding position, a connecting rod is hinged at the middle position of the extension rod, an adjusting rod is fixed on the outer side of the fixed ring, an adjusting ring is slidably arranged on the adjusting rod, and the connecting rod is hinged at the side end of the adjusting ring, and a linkage assembly is arranged between the adjusting ring and the rocker.

[0018] With the above structure, under the action of the linkage assembly, when the rocker is disengaged from the clamp, the adjusting ring moves to the outside of the adjusting rod. At this time, under the pulling of the two connecting rods, the two extension rods approach each other, driving the two support rollers to move, and separating the spun yarn from the hollow roller body. At this time, the two support rollers guide the spun yarn, and the operator can adjust the lateral position of the hollow roller body. When the rocker is stuck in the clamp, the lateral adjustment of the hollow roller body is completed, and the adjusting ring moves in the opposite direction. Similarly, it drives the two support rollers to move to both sides, and the spun yarn contacts the hollow roller body again.

[0019] The fixing ring is rotatably connected to the fixing pipe, and a fastening bolt is arranged on one side of the fixing ring, and the end of the fastening bolt abuts against the side wall of the fixing pipe.

[0020] With the above structure, when installing the equipment, the operator can loosen the fastening bolts, and then rotate the fixing ring to adjust the positions of the two support rollers. According to the contact position between the spun yarn and the hollow roller body, the two support rollers are adjusted to appropriate positions, thereby expanding the application range of the device.

[0021] The linkage assembly includes a baffle fixed to the end of the adjusting rod, a pressure spring is sleeved on the adjusting rod, and the two ends of the pressure spring are respectively against the fixed ring and the adjusting ring, a triangular block is fixed on the adjusting ring, an extrusion ring is slidably provided on the end of the fixed tube, and the outer edge of the extrusion ring is inclined toward the magnified image close to the triangular block, a threaded extrusion rod is threadedly connected to the extrusion ring, a through hole is opened on the vertical plate, the threaded extrusion rod slides through the through hole, and the end of the threaded extrusion rod is against the rocker.

[0022] When the rocker arm is disengaged from the clamp, the adjusting ring is moved toward the baffle plate by the elastic force of the pressure spring and abuts against the baffle plate, and at this time, the inclined surface of the triangular block pushes the extrusion ring outward, so that the extrusion ring abuts against the vertical plate. At this time, the two support rollers move under the action of the pressure spring to separate the spun yarn from the hollow roller body. On the contrary, when the rocker arm is clamped in the clamp, the extrusion ring is pushed by the threaded extrusion rod, and the extrusion ring moves the triangular block and the adjusting ring toward the fixed tube. At this time, the two support rollers move to both sides, and the spun yarn contacts the hollow roller body again. In addition, the operator can adjust the length of the threaded extrusion rod to change the distance the extrusion ring moves when it is squeezed, thereby changing the distance between the two support rollers to adapt to spun yarns with different guide angles, further expanding the scope of application of the device.

[0023] The adjusting rod is a threaded rod, and a limiting nut is threadedly connected to the adjusting rod, and the limiting nut is abutted against one side of the baffle of the adjusting ring.

[0024] With the above structure, when in use, the position of the limit nut on the adjusting rod can be adjusted to limit the maximum distance between the adjusting ring and the baffle, thereby limiting the maximum distance between the two support rollers, preventing the support rollers from being too far apart and causing the annular grooves thereon to fail to limit the lateral deviation of the yarn.

[0025] Compared with the prior art, the textile rubber roller for spun yarn with a shiftable contact position has the following advantages:

[0026] 1. Through the fixed tube, hollow roller body, adjustment mechanism, support roller and support mechanism, the hollow roller body is moved horizontally to one end without stopping the conveying of the spun yarn, so that the spun yarn avoids the worn or aged rubber roller surface, thereby improving the spinning quality, preventing the spun yarn from breaking, and improving the production efficiency.

[0027] 2. By rotating the sleeve, the hollow roller body can be moved to one end of the fixed tube or installed from one end of the fixed tube and fixed by bolts, which makes it convenient to replace the hollow roller body.

[0028] 3. Through the adjustment mechanism, two operators are required to rotate two rockers at the same time and drive two adjusting threaded rods to rotate synchronously to realize the lateral movement of the hollow roller body. This can prevent the operator from accidentally touching the rocker and the vertical plate to drive the hollow roller body to move horizontally and cause the yarn to break, thus playing a safety role.

[0029] 4. Through the support mechanism, the two support rollers can be automatically moved closer when the rocker is toggled to prepare to move the hollow roller body. The support rollers will support the yarn so that the yarn is separated from the surface of the hollow roller body without affecting the movement of the yarn, making the operation more convenient.

[0047] See also Figure 1-12 The present embodiment provides a textile rubber roller for spun yarn with a shiftable contact position, comprising a fixed tube 2 with both ends fixed on a mounting seat 1 and a hollow roller body 3 arranged on the outside of the fixed tube 2, two symmetrically distributed adjustment mechanisms 4 are arranged inside the fixed tube 2, and a rotating sleeve 5 is rotatably arranged on the outside of the adjustment mechanism 4, the inner side of the hollow roller body 3 is fixedly connected to the two rotating sleeves 5, two symmetrically distributed support rollers 6 are arranged on both sides of the hollow roller body 3, and support mechanisms 7 for changing the positions of the support rollers 6 are arranged at both ends of the support rollers 6, and a plurality of annular grooves 8 for limiting the lateral deviation of the spun yarn are opened on the support rollers 6; when in use, the spun yarn bypasses the hollow roller body 3, the support roller 6 is located at the edge of the spun yarn and the spun yarn passes through the support roller 6 The annular groove 8 at the corresponding position on the upper surface can prevent the spun yarn from being laterally offset. When the position where the hollow roller body 3 contacts the spun yarn is aged and worn, the two supporting rollers 6 can be first moved closer to the middle through the supporting mechanism 7 to support the spun yarn and separate it from the hollow roller body 3. At this time, the two rotating sleeves 5 can be moved to one side through the two adjusting mechanisms 4 at the same time, and the rotating sleeves 5 will drive the hollow roller body 3 to move to one end, separating the aging position from the spun yarn position, and then the two supporting rollers 6 are reset to make the spun yarn contact with the hollow roller body 3. This can fully utilize various parts of the hollow roller body 3 to reduce costs, and the hollow roller body 3 can be moved without stopping the machine, thereby ensuring continuous production of spun yarn and improving production efficiency.

[0048] The rotating sleeve 5 includes an annular sleeve 501, a fixed flange 502 is fixed on the outer side of the annular sleeve 501, and a plurality of equally spaced notch grooves 503 and a plurality of equally spaced threaded mounting holes 504 are provided on the fixed flange 502, a plurality of first connecting ears 505 and a plurality of second connecting ears 506 are fixed on the inner side of the hollow roller body 3, and a connecting hole 507 is provided on the first connecting ear 505 and the second connecting ear 506; the first connecting ear 505 and the second connecting ear 506 are respectively located on the outer sides of the two fixed flanges 502, and are fixed to the fixed flange 502 by bolts and threaded mounting holes 504 at corresponding positions, and the operator can remove the bolts from both ends, and the first connecting ear 505 and the second connecting ear 506 can both pass through the notch groove 503, so that the hollow roller body 3 can be removed from the end of the fixed tube 2, so that the hollow roller body 3 can be replaced conveniently.

[0049] The adjusting mechanism 4 includes two bearing seats 402 fixed inside the fixed tube 2, an adjusting threaded rod 401 is rotatably arranged between the two bearing seats 402, and the outer side of the adjusting threaded rod 401 is threadedly connected with a movable sleeve 403, and a plurality of sliders 404 uniformly distributed in a circle are fixed to the outer side of the movable sleeve 403, a plurality of sliding grooves 405 uniformly distributed in a circle are opened on the side wall of the fixed tube 2, and the sliders 404 are slidably arranged in the sliding grooves 405 at corresponding positions, and a rotating bearing 406 is sleeved on the outer side of the slider 404, and the annular sleeve 501 is sleeved on the outer side of the rotating bearing 406, a vertical plate 424 is fixed to the end of the adjusting threaded rod 401 located on the outer side of the fixed tube 2, and a rocker 425 is rotatably arranged on the end of the vertical plate 424 away from the adjusting threaded rod 401, and a clamp 426 for clamping the rocker 425 is fixed on the vertical plate 424; when in use, the operator moves the rocker When 425 is pulled out from the clamp 426, the adjusting threaded rod 401 can be driven to rotate through the rocker 425. The movable sleeve 403 cannot rotate synchronously with the adjusting threaded rod 401 under the limiting action of each slider 404, so it will move along the direction of the slide groove 405 and drive the outer annular sleeve 501 to move. The annular sleeve 501 can drive the hollow roller body 3 to move horizontally to achieve a horizontal movement effect, and the two adjusting mechanisms 4 must be operated by an operator at the same time to drive the hollow roller body 3 to move. When the operator rotates the adjusting threaded rod 401 in one of the adjusting mechanisms 4, the adjusting threaded rod 401 in the other adjusting mechanism 4 will lock the movable sleeve 403, the annular sleeve 501 and the hollow roller body 3, which can prevent the operator from accidentally touching the rocker 425 and the vertical plate 424 to drive the hollow roller body 3 to move horizontally, causing the yarn to break, etc., thereby playing a safety effect.

[0050] A long groove 407 is provided on the outer side of the slider 404, and a moving block 408 is slidably arranged in the long groove 407, and the rotating bearing 406 is sleeved on the outer side of the moving block 408, and circular holes 409 are provided at both ends of the moving block 408, and a return spring 410 is arranged in the circular hole 409, and one end of the return spring 410 located on the outer side of the circular hole 409 is against the inner wall of one end of the long groove 407; since the two adjustment mechanisms 4 need to be adjusted synchronously to produce an effect on the lateral movement of the hollow roller body 3, it is difficult for two operators to achieve synchronous rotation of the adjusting threaded rod 401 at all times. In actual use, when the two operators respectively rotate the adjusting threaded rods 401 in the two adjustment mechanisms 4 and a synchronization error occurs, the moving sleeve 403 can still move slightly without affecting the hollow roller body 3. At this time, the position of the moving block 408 in the long groove 407 changes, so that the two adjusting threaded rods 401 can be slightly out of sync, thereby improving the smoothness of the operation of the operator and facilitating the operation of the operator.

[0051] A first bayonet 411 is provided at the bottom of the moving block 408, a second bayonet 412 is provided at the middle position of the bottom of the long slot 407, and a limiting magnetic block 413 is provided between one of the first bayonet 411 and the second bayonet 412 at the corresponding position, a first long hole 414 is provided at one end of the adjusting threaded rod 401, and a second long hole 415 is provided at the other end, and the first long hole 414 is connected to the second long hole 415, a long rod 416 is slidably provided in the first long hole 414, an annular magnetic sleeve 417 is provided on the outer side of the long rod 416, and a portion of the long rod 416 close to the second long hole 415 is provided. An inner hole 418 is opened at the end, and a spiral groove 419 is arranged on the outer side of the inner hole 418. A fixing rod 420 is slidably arranged in the second long hole 415, and a fixing seat 421 is fixed to one end of the fixing rod 420 located on the outer side of the second long hole 415, and the fixing seat 421 is fixed to the inner wall of the fixing tube 2, and a fixing pin 422 is fixed to the other end of the fixing rod 420, and the fixing pin 422 is slidably arranged in the spiral groove 419. A thrust spring 423 is sleeved on the fixing rod 420, and the two ends of the thrust spring 423 are respectively against the end of the long rod 416 and the bottom wall of the first long hole 414, A push rod 427 is fixed on the rocker 425, and the push rod 427 abuts against one end of the long rod 416 away from the thrust spring 423; the push rod 427 squeezes the long rod 416 inward and compresses the thrust spring 423, and at this time, the annular magnetic sleeve 417 and the same magnetic poles of the limiting magnetic block 413 are close to each other, and under the action of the repulsive force, the limiting magnetic block 413 abuts against the first bayonet 411, so that there will be no relative sliding between the moving block 408 and the moving sleeve 403, and then when the operator accidentally touches one of the vertical plates 424 and the rocker 425, the moving sleeve 403 will not move, further The position of the outer hollow roller body 3 is restricted. When the rocker arm 425 pulls out the clamp 426, the push rod 427 no longer resists the long rod 416. At this time, under the action of the thrust spring 423, the long rod 416 moves outward. At this time, under the action of the fixing pin 422 and the spiral groove 419, the long rod 416 will rotate. At this time, the magnetic pole of the annular magnetic sleeve 417 is reversed, and suction is generated on the limiting magnetic block 413, so that the limiting magnetic block 413 is disengaged from the first clamp 411. At this time, when the operator rotates the two adjusting threaded rods 401, a small degree of asynchronism can be allowed to improve the smoothness of operation.

[0052] The supporting mechanism 7 includes a fixed ring 701 fixedly arranged at the end of the fixed tube 2 and two rotating rings 702 rotatably arranged at the end of the fixed tube 2, and an extension rod 703 is fixed on the rotating ring 702, and the end of the extension rod 703 is rotatably connected to the end of the supporting roller 6 at the corresponding position, and a connecting rod 704 is hinged at the middle position of the extension rod 703, and an adjusting rod 705 is fixed on the outer side of the fixed ring 701, and an adjusting ring 706 is slidably arranged on the adjusting rod 705, and the connecting rod 704 is hinged at the side end of the adjusting ring 706, and a linkage assembly is arranged between the adjusting ring 706 and the rocker 425; Under the action, when the rocker 425 is disengaged from the clamp 426, the adjusting ring 706 moves to the outside of the adjusting rod 705. At this time, under the pulling of the two connecting rods 704, the two extension rods 703 approach each other, driving the two supporting rollers 6 to move, and the spun yarn is separated from the hollow roller body 3. At this time, the two supporting rollers 6 guide the spun yarn, and the operator can adjust the lateral position of the hollow roller body 3. When the rocker 425 is stuck in the clamp 426, the lateral adjustment of the hollow roller body 3 is completed, and the adjusting ring 706 moves in the opposite direction.

[0056] The above fixing methods are the most commonly used fixing connection methods in this field, such as welding, bolt connection, etc.

[0057] Working principle of the present invention:

[0058] The spun yarn passes around the hollow roller body 3, the supporting roller 6 is located at the edge of the spun yarn and the spun yarn passes through the annular groove 8 at the corresponding position on the supporting roller 6. At this time, the annular groove 8 can prevent the spun yarn from being laterally offset. In addition, when installing the equipment, the operator can loosen the fastening bolts 707, and then rotate the fixing ring 701 to adjust the positions of the two supporting rollers 6. According to the contact positions of the spun yarn and the hollow roller body 3, the two supporting rollers 6 are adjusted to appropriate positions, thereby expanding the scope of application of the device. When the contact position between the hollow roller body 3 and the spun yarn is aged and worn, when the rocker 425 is disengaged from the clamp 426, the adjusting ring 706 is moved toward the baffle 708 by the elastic force of the pressure spring 709 and abuts against the baffle 708. At this time, the inclined surface of the triangular block 710 pushes the extrusion ring 711 outward, so that the extrusion ring 711 abuts against the vertical plate 424. At this time, under the action of the pressure spring 709, the adjusting ring 706 The two supporting rollers 6 are reset again, so that the yarn contacts the hollow roller 3, and the various parts of the hollow roller 3 are fully utilized, and the cost is reduced. Moreover, the hollow roller 3 can be moved without stopping the machine, so as to ensure the continuous production of the yarn and improve the production efficiency.

[0059] Moreover, when the operator accidentally touches one of the vertical plates 424 and the rocker 425, the movable sleeve 403 will not move, further restricting the position of the outer hollow roller body 3. When the rocker 425 pulls out the clamp 426, the push rod 427 no longer resists the long rod 416. At this time, under the action of the thrust spring 423, the long rod 416 moves outward. At this time, under the action of the fixing pin 422 and the spiral groove 419, the long rod 416 will rotate. At this time, the magnetic pole of the annular magnetic sleeve 417 is reversed, generating suction on the limiting magnetic block 413, so that the limiting magnetic block 413 is disengaged from the first bayonet 411. At this time, when the operator rotates the two adjusting threaded rods 401, a small degree of asynchronism can be allowed to improve the smoothness of operation.

[0060] In addition, the first connecting ear 505 and the second connecting ear 506 are respectively located on the outer sides of the two fixed flanges 502, and are fixed to the fixed flanges 502 by bolts and threaded mounting holes 504 at corresponding positions. The operator can remove the bolts from both ends, and the first connecting ear 505 and the second connecting ear 506 can both pass through the notch groove 503, so that the hollow roller body 3 can be removed from the end of the fixed tube 2, which is convenient for replacing the hollow roller body 3.

[0061] 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.
