Description

Technical Field

[0001] The present invention belongs to the technical field of textile equipment, and particularly relates to a textile rubber roller with stable movement and reliable connection. Background Art

[0002] Textile originally refers to the general term for spinning and weaving. Modern textile and printing and dyeing usually cannot do without rubber rollers. A rubber roller is a roller-shaped product with a metal or other material as the core and a rubber outer covering vulcanized. Although the existing textile rubber rollers can be disassembled and assembled conveniently, the movement is not stable under impact such as sudden stop, and the connection between each component is unreliable, resulting in unreliable movement.

[0003] After retrieval, for example, a Chinese patent document discloses a rubber roller convenient for installation

Application No.: CN201821144391.4; Publication No.: CN208898225U

[0004] The purpose of the present invention is to address the above problems existing in the prior art and propose a textile rubber roller with stable movement and reliable connection. The technical problem to be solved by this device is: how to ensure that the textile rubber roller is convenient for disassembly and assembly, while having high reliability in movement transmission and connection strength, and can maintain stable movement when impacted.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A textile rubber roller with stable movement and reliable connection includes a fixed bearing seat and a moving seat. Both the fixed bearing seat and the moving seat are fixed on the frame. A stepped shaft is arranged in the fixed bearing seat. A sliding bearing seat is slidably arranged on the moving seat. A spline sleeve is arranged in the sliding bearing seat. An outer cover is fixed at the end of the spline sleeve. An end cover is connected to the spline sleeve. A shaft core is arranged between the stepped shaft and the end cover. A locking support sleeve is arranged between the stepped shaft and the shaft core. A sealing cover, a counterweight shaft, an outer waterproof cover plate, an inner waterproof cover plate, and damping liquid are arranged in the shaft core. A rubber shell is sleeved and fixed on the shaft core, and a rubber layer is sleeved and fixed on the rubber shell.

[0007] The working principle of the present invention is as follows: The sliding bearing seat is fixed on the moving seat by bolts. By moving the sliding bearing seat, it is convenient to replace the parts on the rubber roller. The rubber roller can be driven to rotate integrally through the stepped shaft connected to the motor. Through spline connection, the rotation is reliable. The outer cover can fix the spline sleeve and the end cover. By setting the locking support sleeve, the connection between the stepped shaft and the shaft core can be strengthened and it plays a role in strengthening the support. By setting the counterweight shaft and the damping liquid, the rubber roller can rotate stably and absorb the vibration impact during rotation or sudden stop. By setting a rubber layer outside the rubber shell, when the rubber surface is damaged, it is convenient to replace the rubber layer without replacing the whole rubber roller, which is convenient to operate and saves time and cost.

[0008] One end of the shaft core is the shaft core connection end, and the other end of the shaft core is provided with a cavity. Symmetrical shaft core flat grooves are arranged outside the cavity. A shaft core spline groove is opened in the shaft core connection end, and a rubber shell flat section is opened in the rubber shell.

[0009] The sealing cover is fixed at the end of the cavity. One end of the counterweight shaft is rotatably arranged at the bottom of the cavity, and the other end of the counterweight shaft is rotatably arranged on the sealing cover. The inner waterproof cover plate and the outer waterproof cover plate are respectively installed at both ends of the cavity. A liquid injection pipe is arranged on the outer waterproof cover plate, and the liquid injection pipe penetrates through the sealing cover. The damping liquid is filled in the cavity.

[0010] With the above structure, the counterweight shaft can rotate relative to the shaft core to maintain balance. Through the viscous resistance between the counterweight shaft and the shaft core and the damping liquid respectively, when the shaft core is impacted, the kinetic energy can be attenuated to maintain stable rotation. The inner waterproof cover plate and the outer waterproof cover plate can prevent the damping liquid from overflowing, and the damping liquid can be added or discharged through the liquid injection pipe.

[0011] The stepped shaft is successively provided with an outer connection section, a rotating section, a fixed section and a spline section from outside to inside. The outer connection section is connected to the output shaft of the motor, the rotating section is rotatably arranged in the fixed bearing seat, and the spline section is in spline fit with the shaft core spline groove.

[0012] With the above structure, power is provided for the whole rubber roller through the connection between the outer connection section and the output shaft of the motor. The rotating section is matched with the bearing in the fixed bearing seat, and the spline section is in spline fit with the shaft core spline groove to ensure the rotation reliability of the connection part and facilitate the disassembly and assembly of the shaft core.

[0013] The outer diameters of the fixed section and the shaft core connection end are the same, and the outer diameters of the fixed section and the shaft core connection end are equal to the inner diameter of the locking support sleeve. The locking support sleeve is sleeved on the fixed section and the shaft core connection end. Two rows of a number of circumferentially evenly distributed locking threaded holes are opened on the locking support sleeve, and the two rows of locking threaded holes are respectively located above the fixed section and the shaft core connection end.

[0014] With the above structure, the locking support sleeve is sleeved on the fixed section and the connecting end of the shaft core. By setting a setscrew in the locking threaded hole, the stepped shaft and the shaft core can be locked, strengthening the connection reliability. When disassembling and assembling the shaft core, only the setscrew needs to be rotated, which is convenient for operation.

[0015] A flat cut surface of the end cover is provided inside the end cover. The flat cut surface of the end cover and the flat cut surface of the rubber shell are respectively in sliding fit with the flat groove on the shaft core. A spline shaft of the end cover is provided at the end of the end cover. The spline shaft of the end cover is fixed on the outer cover. The outer diameters of the end cover and the locking support sleeve are both larger than the outer diameter of the shaft core, and the outer diameters of the end cover and the locking support sleeve are both smaller than the outer diameter of the rubber shell.

[0016] With the above structure, by the flat cut surface of the end cover and the flat cut surface of the rubber shell respectively cooperating with the flat groove on the shaft core, the rotation and connection reliability are ensured, avoiding relative sliding and thus affecting the textile quality. The outer diameters of the end cover and the locking support sleeve are both larger than the outer diameter of the shaft core, which can conveniently fix the rubber shell.

[0017] A plurality of uniformly distributed fixing holes are provided on the sliding bearing seat. A spline groove inside the spline sleeve is provided. The spline groove inside the spline sleeve cooperates with the spline shaft of the end cover. A plurality of circumferentially uniformly distributed outer peripheral holes are provided on the outer cover. A central hole is provided at the center of the outer cover. The outer peripheral holes and the central hole are respectively located outside the spline sleeve and the spline shaft of the end cover.

[0018] With the above structure, the sliding bearing seat is fixed by setting bolts in the fixing holes. The spline groove inside the spline sleeve cooperates with the spline shaft of the end cover, ensuring the reliability of the rotation of the rubber roller. The outer cover is respectively connected to the spline sleeve and the spline shaft of the end cover by bolts, which can fix the relative position between the spline sleeve and the end cover.

[0019] Compared with the prior art, the textile rubber roller of the present invention with stable movement, reliable connection and convenient disassembly and assembly has the following advantages:

[0020] 1. Through the viscous resistance generated between the counterweight shaft and the shaft core and the damping liquid respectively, when the shaft core is impacted, the kinetic energy can be attenuated, and the shaft core can maintain stable rotation. And through the cooperation of each part by splines or flat grooves and setting the locking support sleeve, the reliability of rotation transmission and connection strength can be ensured, and the movement is reliable;

[0021] 2. The outer diameters of the end cover and the locking support sleeve are both larger than the outer diameter of the shaft core, which is convenient for limiting the rubber shell, fixing the rubber shell and facilitating the replacement of the rubber surface;

[0022] 3. The structural design of each part is reasonable, meeting the interchangeability. Only by removing the sliding bearing seat, the parts on the rubber roller can be conveniently replaced without replacing the whole rubber roller, which is convenient for operation, saving time and cost.

Inject the damping liquid 16 through the liquid injection pipe 11a. The counterweight shaft 10 and the bearing in the sealing cover 9 are in clearance fit to complete the installation of the entire shaft core 7. Then, fit and fix the rotating section 3b with the bearing in the fixed bearing seat 1, sleeved the locking support sleeve 8 on the fixed section 3c and lock it with a set screw. Sleeve the shaft core connection end 7a in the locking support sleeve 8 and lock it. The spline section 3d and the shaft core spline groove 7b are connected by splines to ensure the reliability of rotation and facilitate the disassembly and assembly of the shaft core 7. Sleeve the rubber shell 12 provided with the adhesive layer 13 on the shaft core 7, and then fix the end cover spline shaft 6a on the outer cover 14. The inner spline groove 5a of the sleeve is matched with the end cover spline shaft 6a to ensure the reliability of the rotation of the rubber roller. Move the sliding bearing seat 4 to make the end cover flat section 6b match with the shaft core flat groove 7d. The end face of the end cover 6 abuts against the rubber shell 12 to position the rubber shell 12, and fix the sliding bearing seat 4 on the moving seat 2 with bolts to complete the installation of the entire rubber roller.

[0040] The present invention can drive the whole rubber roller to rotate by connecting the stepped shaft 3 with the motor. The counterweight shaft 10 can rotate relative to the shaft core 7 to maintain balance. Through the viscous resistance between the counterweight shaft 10 and the shaft core 7 and the damping liquid 16 respectively, when the shaft core 7 is impacted, the kinetic energy can be attenuated to maintain stable rotation. When the rubber roller rotates, the locking support sleeve 8 can strengthen the connection between the stepped shaft 3 and the shaft core 7 and play a role in strengthening the support. By matching the end cover flat section 6b and the rubber shell flat section 12a with the shaft core flat groove 7d respectively, the reliability of rotation and connection can be ensured, and relative sliding can be avoided, thus affecting the textile quality.

[0041] The structures of the various parts of the present invention are reasonably designed to meet the interchangeability. The outer diameters of the end cover 6 and the locking support sleeve 8 are both larger than the outer diameter of the shaft core 7, which can conveniently fix the rubber shell 12. When the rubber surface or other parts are damaged, only by removing the sliding bearing seat 4, the parts on the rubber roller can be conveniently replaced without replacing the whole rubber roller, which is convenient to operate, saving time and cost. Each rotating part is connected by splines, and the rotation is reliable.

[0042] In summary, through the viscous resistance generated between the counterweight shaft 10 and the shaft core 7 and the damping liquid 16 respectively, when the shaft core 7 is impacted, the kinetic energy can be attenuated to maintain stable rotation. And through the cooperation of the splines or flat grooves between the various parts, and the setting of the locking support sleeve 8, the reliability of rotation transmission and connection strength can be ensured, and the movement is reliable. The outer diameters of the end cover 6 and the locking support sleeve 8 are both larger than the outer diameter of the shaft core 7, which is convenient for limiting the rubber shell 12, fixing the rubber shell 12 and replacing the rubber surface. The structures of the various parts are reasonably designed to meet the interchangeability. Only by removing the sliding bearing seat 4, the parts on the rubber roller can be conveniently replaced without replacing the whole rubber roller, which is convenient to operate, saving time and cost.
