Description

Technical Field

[0001] This invention relates to the field of textile machinery rubber rollers, specifically to a telescopic textile machinery rubber roller that is easy to adjust. Background Technology

[0002] Textile machinery rubber rollers are roller-shaped products made by vulcanizing rubber with a metal or other material core. A typical rubber roller consists of an outer rubber layer, a hard rubber layer, a metal core, a roller neck, and ventilation holes. Its processing includes roller core sandblasting, bonding treatment, rubber forming, fabric wrapping, wire winding, vulcanization in a vulcanizing tank, and surface finishing. During processing, damage to the outer wall surface necessitates replacement of the entire structure, which is wasteful. Furthermore, in practical applications, different types of guidance or transmission require different roller lengths, and existing rollers cannot achieve self-adjustment of length, limiting their applicability. This necessitates disassembly and replacement of the roller, which is time-consuming. Therefore, we propose an easily adjustable telescopic textile machinery rubber roller. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an easily adjustable telescopic textile machine rubber roller, thus solving the aforementioned problems.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solution: an easily adjustable telescopic textile machine rubber roller, comprising a connecting shaft and a telescopic roller body, wherein the connecting shaft is respectively disposed on both sides of the telescopic roller body, and the outer side of the telescopic roller body is wrapped with a deformable and stretchable rubber layer, wherein the telescopic roller body is composed of a central connecting circular block, two sets of moving tubes and two rotating structures, wherein the two sets of moving tubes are respectively disposed on both sides of the central connecting circular block, one side of the rotating structure is connected to the central connecting circular block, and the other side of the rotating structure is connected to a side block.

[0006] Preferably, the rotating structure includes a lead screw and a guide assembly. A circular block is fixedly installed inside the movable sleeve. The circular block has a threaded hole. The lead screw is threadedly connected to the threaded hole on the circular block. A bearing seat is fixedly installed on the intermediate connecting circular block at the position corresponding to the lead screw. The bearing seat is rotatably connected to one end of the lead screw. The external threads of the lead screw at the two ends corresponding to the two circular blocks are in opposite directions.

[0007] Preferably, the guide assembly includes a side connecting tube with a through opening. One end of the lead screw extends into the side connecting tube. A U-shaped groove is provided on the side connecting tube. A U-shaped opening is provided on the side of the movable sleeve near the central connecting block. Side groove one and side groove two are respectively provided on the inner walls of the U-shaped groove and the U-shaped opening. Multiple sets of U-shaped inserts are fixedly installed on the central connecting block and the movable sleeve at the positions corresponding to the U-shaped opening and the U-shaped groove, respectively. Strip-shaped protrusions are fixedly installed on both sides of the U-shaped inserts, and the strip-shaped protrusions are slidably engaged with the U-shaped inserts.

[0008] Preferably, the end of the lead screw extending into the side connecting tube has a hexagonal hole, a rod is inserted into the hexagonal hole, a tension spring is fixedly installed inside the hexagonal hole, one end of the tension spring is fixedly connected to the rod, a rotating block is fixedly installed at the end of the rod, and multiple sets of grooves are equally spaced on the inner wall of the side connecting tube, arranged in a ring array around the lead screw, and a locking rod is fixedly installed on the rotating block at the position corresponding to the groove.

[0009] Preferably, the cross-section of the rotating block is hexagonal.

[0010] Preferably, the connecting shaft includes a threaded rod, a nut, and a hinge assembly. The threaded rod is fixedly installed on the side of the side block, and a nut is threaded onto the threaded rod. The hinge assembly is connected to the threaded rod.

[0011] Preferably, the hinge assembly includes two hinge rods and a connecting shaft. The connecting shaft has a rectangular groove, and the inner wall of the rectangular groove has a transverse groove. The hinge rod is slidably engaged with the transverse groove on the inner wall of the rectangular groove. The threaded rod has a rectangular groove, and the hinge rod is hinged with the inner wall of the rectangular groove.

[0012] Preferably, an inner wall groove is formed on the inner wall of the adhesive layer, and multiple sets of triangular annular grooves are formed at equal intervals on the top inner wall of the inner wall groove, and a corrugated pipe is fixedly installed inside the inner wall groove.

[0013] Compared with the prior art, the present invention provides an easily adjustable telescopic textile machine rubber roller, which has the following beneficial effects:

[0014] 1. This easily adjustable telescopic textile machine rubber roller has a rotating structure that drives two movable sleeves on one side to slide towards each other or towards each other, thereby changing the length of one side. Then, the other side is adjusted to complete the adjustment of the length on both sides, thus adapting to different types of work requirements.

[0015] 2. The easily adjustable telescopic textile machine rubber roller, with its U-shaped insert, provides guidance for the movable sleeve during movement. It also provides support in the gaps between the two movable sleeves and between the movable sleeves and the intermediate connecting block and the side connecting pipe, thus supporting the frame and preventing the roller from failing to achieve its normal support effect in the gaps.

[0016] 3. This easily adjustable telescopic textile machine roller allows for easy adjustment of the lead screw position. When the lead screw needs to be rotated, the rotating block is pulled outward, which stretches the tension spring. Then, the lead screw can be rotated. When the lead screw needs to be fixed, the rotating block is released, and the locking rod is inserted into the corresponding groove to lock the lead screw position, preventing it from rotating arbitrarily and causing the movable sleeve to change position when the telescopic roller rotates.

[0017] 4. This easily adjustable telescopic textile machine rubber roller allows for easy adjustment of the lateral position of the movable sleeve. When the lead screw needs to be rotated, the shim is inserted between the lead screw and the rotating block. At this time, the locking rod is no longer engaged with the groove. Then, a wrench is inserted into the side connecting tube through the opening, and the rotating block is rotated. This design facilitates the rotation of the rotating block to drive the lead screw to rotate, thereby achieving the effect of easily adjusting the lateral position of the movable sleeve.

[0018] 5. This easily adjustable telescopic textile machine roller, when installed, involves rotating the nut to move it closer to the side block. The nut then no longer engages with the hinge rod. The two hinge rods are then slid apart, causing the other end of the hinge rod to tilt outwards. This reduces the distance between the connecting shaft and the rectangular groove, allowing the length of the connecting shaft to be changed. The connecting shaft is then aligned with the mounting hole on the equipment. The nut is then rotated to move it closer to the connecting shaft. Once the nut engages with the side of the hinge rod, the hinge rod returns to its original position, and the distance between the connecting shaft and the rectangular groove returns to normal. This design allows for changing the length of the connecting shaft during installation, effectively solving the problem of existing equipment requiring tilting and hoisting, which is time-consuming and labor-intensive.

[0019] 6. This easily adjustable telescopic textile machine rubber roller, when the rubber layer stretches or shrinks, the corrugated pipe will stretch accordingly, filling the interior of the inner wall groove, and can be supported by U-shaped blocks in the gaps between the two movable sleeves and between the movable sleeves and the middle connecting round block and the side connecting pipe.

[0020] 7. This easily adjustable telescopic textile machine rubber roller can be reused after the outer wall of the rubber layer is damaged. It can be heated to remove the rubber layer from the telescopic roller body, and then a new rubber layer can be taken out. Glue is applied to the inner walls on both sides of the rubber layer, and the inner walls of the rubber layer are re-adhere to the telescopic roller body. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: An easily adjustable telescopic textile machine rubber roller includes a connecting shaft and a telescopic roller body 2. The connecting shaft is respectively disposed on both sides of the telescopic roller body 2. The outer side of the telescopic roller body 2 is wrapped with a deformable and stretchable rubber layer 1. The telescopic roller body 2 consists of a central connecting block 9, two sets of moving tubes, and two rotating structures. The two sets of moving tubes are respectively disposed on both sides of the central connecting block 9. One side of the rotating structure is connected to the central connecting block 9, and the other side of the rotating structure is connected to the side block 13. During processing, the length of the telescopic roller body 2 needs to be adjusted to adapt to the current type of work. Rotating the rotating structure causes the two movable sleeves 11 on one side to slide towards the opposite side or towards the side, thereby changing the length of one side. Then, the other side is adjusted to complete the adjustment of the length of both sides, thus adapting to different types of work requirements.

[0033] The movable tube consists of two movable sleeves 11 that can move away from or close to each other on one side. The two movable sleeves 11 are located between the central connecting round block 9 and the side block 13.

[0034] The rotating structure includes a lead screw 12 and a guide assembly. A circular block 20 is fixedly installed inside the movable sleeve 11. A threaded hole is opened on the circular block 20. The lead screw 12 is threadedly connected to the threaded hole on the circular block 20. A bearing seat 10 is fixedly installed on the intermediate connecting circular block 9 at the position corresponding to the lead screw 12. The bearing seat 10 is rotatably connected to one end of the lead screw 12. The external threads of the lead screw 12 at the two ends of the two circular blocks 20 are opposite in direction.

[0035] The guide assembly includes a side connecting tube 17 with a through opening 18. One end of the lead screw 12 extends into the side connecting tube 17. A U-shaped groove 15 is provided on the side connecting tube 17. A U-shaped opening 21 is provided on the side of the movable sleeve 11 near the central connecting block 9. Side groove 16 and side groove 22 are respectively provided on the inner walls of the U-shaped groove 15 and the U-shaped opening 21. Multiple sets of U-shaped inserts 23 are fixedly installed on the central connecting block 9 and the movable sleeve 11 at the positions corresponding to the U-shaped opening 21 and the U-shaped groove 15. Strip-shaped protrusions 24 are fixedly installed on both sides of the U-shaped inserts 23. The strip-shaped protrusions 24 are slidably engaged with the U-shaped inserts 23. The device provides guidance for the movable sleeve 11 during movement and provides support for the gaps between the two movable sleeves 11 and between the movable sleeves 11 and the intermediate connecting block 9 and the side connecting pipe 17, thus achieving the effect of supporting the skeleton and preventing the roller from failing to achieve normal support at the gaps. When the length needs to be adjusted, the screw 12 is rotated. Under the action of the opposite external threads on both sides of the screw 12, the movable sleeves 11 on both sides will slide, thereby changing the distance between the two movable sleeves 11 and achieving the effect of changing the length of the telescopic roller body 2. When the movable sleeves 11 slide, the telescopic roller body 2 will be stretched and deformed, thereby achieving the change of length without changing the surface.

[0036] In Example 2, based on Example 1, since the telescopic roller body 2 as a whole needs to rotate, the lead screw 12 will inevitably rotate under the influence of rotation. Therefore, when the telescopic roller body 2 rotates, it is not possible to effectively keep the positions of the two movable sleeves 11 constant. Therefore, it is necessary to fix the lead screw 12.

[0037] In summary, the lead screw 12 extends into the side connecting tube 17 and has a hexagonal hole at one end. A rod 25 is inserted into the hexagonal hole, and a tension spring 26 is fixedly installed inside the hexagonal hole. One end of the tension spring 26 is fixedly connected to the rod 25. A rotating block 14 is fixedly installed at the end of the rod 25. Multiple sets of grooves 19 are equally spaced on the inner wall of the side connecting tube 17. These grooves are arranged in a ring array around the lead screw 12, and the rotating block 14 corresponds to the grooves. A locking rod 27 is fixedly installed at position 19. When it is necessary to rotate the lead screw 12, the rotating block 14 is pulled outward, at which time the tension spring 26 is stretched, and then the lead screw 12 can be rotated. When it is necessary to keep the lead screw 12 fixed, the rotating block 14 is released, and then the locking rod 27 is inserted into the corresponding groove 19 to lock the position of the lead screw 12, preventing the lead screw 12 from rotating arbitrarily and preventing the lead screw 12 from rotating when the telescopic roller 2 rotates, causing the position of the movable sleeve 11 to change.

[0038] The cross-section of the rotating block 14 is hexagonal. When it is necessary to rotate the lead screw 12, the shim is inserted between the lead screw 12 and the rotating block 14. At this time, the locking rod 27 is no longer engaged with the groove 19. Then, a wrench is inserted into the side connecting tube 17 through the opening 18, and then the rotating block 14 is rotated. This setting makes it easy to rotate the rotating block 14 to drive the lead screw 12 to rotate, thereby achieving the effect of easily adjusting the lateral position of the movable sleeve 11.

[0039] Example 3: When installing the rubber roller, the connecting shafts on both sides need to be snapped into the mounting holes on both sides of the equipment. The existing rubber roller disassembly operation is quite cumbersome. Due to the weight of the rubber roller of the textile machine, it is generally necessary to use a crane for hoisting. Moreover, the space is small during installation, and the rubber roller needs to be hoisted at an angle during installation. As a result, replacing the rubber roller often consumes a lot of time, which is extremely inconvenient and inefficient.

[0040] In summary, the connecting shaft includes a threaded rod 3, a nut 8, and a hinge assembly. The threaded rod 3 is fixedly installed on the side of the side block 13, and the nut 8 is threadedly connected to the threaded rod 3. The hinge assembly is connected to the threaded rod 3.

[0041] The hinge assembly includes two hinge rods 5 and a connecting shaft 6. The connecting shaft 6 has a rectangular groove 7, and the inner wall of the rectangular groove 7 has a transverse groove. The hinge rod 5 is slidably engaged with the transverse groove on the inner wall of the rectangular groove 7. The threaded rod 3 has a rectangular groove 4, and the hinge rod 5 is hinged to the inner wall of the rectangular groove 4. When installation is required, the nut 8 is rotated, causing the nut 8 to move closer to the side block 13. The nut 8 is then no longer engaged with the hinge rod 5. The two hinge rods 5 on both sides are then slid away from each other. The other hinge rod 5... The end is tilted outward, and the distance between the connecting shaft 6 and the rectangular groove 4 becomes smaller. This setting can change the length of the connecting shaft. Then, the position of the connecting shaft 6 is aligned with the mounting hole on the equipment. Then, the nut 8 is rotated so that the nut 8 moves closer to the connecting shaft 6. After the nut 8 is in contact with the side of the hinge rod 5, the hinge rod 5 returns to its original position, and then the distance between the connecting shaft 6 and the rectangular groove 4 returns to its original position. This setting can change the length of the connecting shaft during installation, effectively solving the problem that the existing equipment needs to be tilted and hoisted during installation, which is time-consuming and labor-intensive.

[0042] Example 4, based on Example 1: An inner wall groove 28 is provided on the inner wall of the adhesive layer 1. Multiple sets of triangular annular grooves are equally spaced on the top inner wall of the inner wall groove 28. A corrugated pipe 29 is fixedly installed inside the inner wall groove 28. When the adhesive layer 1 is stretched or contracted, the corrugated pipe 29 will stretch accordingly and fill the inside of the inner wall groove 28. It can be supported by a U-shaped insert 23 in the gap between the two movable sleeves 11 and the gap between the movable sleeves 11 and the middle connecting round block 9 and the side connecting pipe 17.
