Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of textile machines, and relates to a textile rubber roller, in particular to a textile rubber roller capable of transverse adjustment. BACKGROUND

[0002] The rubber roller is a roller-shaped product made of metal or other materials as a core and coated with rubber after vulcanization. The textile rubber roller made of polyurethane has lower wear and tear, better resilience, and does not need to be ground and processed. No coating layer is needed before use, and no winding phenomenon occurs. The rubber roller does not need to be ground and repaired during use. The production cost and production efficiency of the producer and user can be reduced.

[0003] The textile rubber roller is generally used for guiding. The surface of the guiding rubber roller for yarn is generally provided with a plurality of wire grooves. In actual production, the distance between yarns is large, and there are generally several idle wire grooves between adjacent two yarns. With long-time use of the rubber roller, the wire groove part in contact with the yarn is severely worn, but the idle wire groove is not worn. Therefore, the rubber roller is generally moved transversely by a distance to match the yarn with the adjacent idle wire groove. However, the existing rubber roller cannot be transversely adjusted, and the bearing seat needs to be adjusted. The adjustment process is complicated and is not conducive to improving production efficiency.

[0004] Based on this, a textile rubber roller capable of transverse adjustment is designed. SUMMARY

The two ends of the shaft body are rotatably connected to the two bearing seats. The shaft body is tubular, and the adjusting rod is located inside the shaft body. A plurality of long grooves are formed in the wall of the shaft body. A plurality of connecting blocks are fixed to the outer side of the adjusting rod. The rubber surface is in the form of a cylinder and is sleeved outside the shaft body. A connecting mechanism is arranged between the connecting blocks and the rubber surface. The adjusting mechanism is arranged at one end of the shaft body and comprises a threaded rod, a rotating block and an adjusting disc. An installation groove is formed at one end of the shaft body. The adjusting disc is rotatably arranged in the installation groove. A row of teeth is arranged on the outer side of the adjusting disc.

[0008] The working principle of the application is as follows: in actual use, when the thread groove on the rubber surface that cooperates with the yarn is worn out, the adjusting disc can be rotated, the rotating block and the threaded rod are driven to rotate through the meshing of the teeth and the transmission teeth, the adjusting rod is driven to move horizontally in the shaft body, the adjusting rod drives the rubber surface to move horizontally through the connecting block, the thread groove on the rubber surface is dislocated, the yarn cooperates with the thread groove that is not worn out, the utilization rate of the rubber roller is improved, the operator no longer needs to move the bearing seat at both ends, the horizontal adjustment of the rubber roller is not needed after the movement, the operation steps are simplified, the production efficiency is improved, and when all the thread grooves on the rubber surface are fully used and worn out, the fixing of the rubber surface can be released through the connecting mechanism, and then the rubber surface is replaced, the whole textile rubber roller does not need to be replaced, and the production cost is reduced.

[0009] The outer side of the rotating block is provided with an annular groove, a fixed ring is rotationally arranged in the annular groove, a plurality of fixed blocks are fixedly arranged on the outer side of the fixed ring at equal intervals, the side, away from the fixed ring, of the fixed block is fixedly connected with the inner wall of the shaft body, a sliding rod is fixed to the end, away from the threaded hole, of the threaded rod, a limiting strip is arranged at the side end of the sliding rod, the rotating block is slidingly sleeved on the outer side of the sliding rod, a limiting groove matched with the limiting strip is formed in the inner side of the rotating block, and the end, away from the threaded rod, of the sliding rod is provided with an expansion assembly.

[0010] By adopting the above structure, the transverse movement of the threaded rod is limited by the expansion assembly, and when the threaded rod is driven to move transversely by the expansion assembly, the rotating block can only rotate under the limiting action of the fixed ring and cannot move, so the meshing relationship with the adjusting disc can always be maintained, and when the sliding rod moves transversely, the rotating block can drive the sliding rod and the threaded rod to rotate under the action of the limiting strip.

[0011] The expansion assembly comprises an expansion disc and a moving ring, the expansion disc is rotationally arranged in the mounting groove, a vortex groove is formed in the side end of the expansion disc, the moving ring is rotationally connected to the end, away from the threaded rod, of the sliding rod, a sliding block is fixed to the side end of the moving ring, the sliding block is slidingly arranged in the vortex groove, and a tab is arranged at the side end of the sliding block.

[0012] By adopting the above structure, after the adjustment of the adjusting disc is completed, if the position of the rubber surface needs to be continuously adjusted, the expansion disc can be rotated, the sliding block is driven to move under the action of the vortex groove, and then the sliding rod and the threaded rod are driven to move, so the position of the adjusting rod can be further adjusted, the range of transverse adjustment of the rubber surface is expanded, and when the adjusting disc is rotated, the threaded rod itself will not move transversely under the action of the sliding block when the rotating block drives the threaded rod to rotate, so the movement stability of the adjusting rod is ensured and the equipment is prevented from being stuck.

[0017] The extrusion assembly comprises a mounting ring, an extrusion block and an extrusion rod; the shaft body is provided with a square groove corresponding to the position of the extrusion groove; the mounting ring is provided in two numbers and is fixed on the outer side of the shaft body and located on the two sides of the square groove; the extrusion block is hingedly arranged in the square groove; the extrusion rod is hingedly arranged in the extrusion groove, and the end of the extrusion rod abuts against the chamfer of the moving rod; one side of the extrusion block abuts against the inner side of the bearing seat, and the other side is rotatably provided with a rotating wheel abutting against the extrusion rod.

[0018] With the above structure, after the shaft body is installed, the bearing seat is located outside the installation ring, the extrusion block is extruded inward, and the extrusion rod is extruded inward through the rotating wheel, then the moving rod is pushed to move by the extrusion rod, without the need for the operator to perform other operations, and the locking can be automatically performed after installation, and after installation is completed, the situation of falling off does not occur, and in the process of adjusting the adjusting rod, when the adjusting rod and the extrusion rod move synchronously, the rotating wheel on the extrusion block is always extruded on the extrusion rod, and the rolling friction between the two does not generate large resistance to the movement of the adjusting rod, facilitating the operator to adjust.

[0021] Compared with the prior art, the textile rubber roller capable of being adjusted transversely has the following advantages:

[0022] 1.
