Description

Technical Field

[0001] The utility model relates to the technical field of rubber rollers, in particular to a textile rubber roller with adjustable length. Background Art

[0002] Rubber rollers are roll-shaped products made of metal or other materials as the core and rubber covered by vulcanization. According to the surface morphology, they can be divided into: flat rollers and patterned rubber rollers. Rubber rollers are also one of the important components of textile machinery. The quality and performance of rubber rollers directly affect the quality and output of yarn. However, the existing rubber rollers are all fixed in length and cannot meet people's needs for winding fabrics of different sizes. Therefore, a length-adjustable textile rubber roller is needed.

[0003] For example, the prior art: CN211648779U, a spliced ​​adjustable textile rubber roller, includes a roller core and a locking screw ring, a plurality of spliced ​​rubber rollers are arranged on the roller core, the spliced ​​rubber rollers are sleeved together in sequence, the locking screw ring is threadedly mounted on one end of the roller core, and the locking screw ring abuts against the end of the spliced ​​rubber roller.

[0004] There are other existing technologies:

[0005] CN211169170U, a length-adjustable rubber roller for textile use;

[0006] CN213387277U, a length-adjustable thread winding roller for textile use.

[0007] The length-adjustable textile rubber roller mentioned in the above-mentioned prior art increases or decreases the length of the rubber roller by splicing, and gaps are inevitably generated at each interface by splicing. Since the cross-sectional direction of the splicing is often consistent with the winding direction, this means that during winding, the textile and some thread ends will be easily affected by the winding tension and fall into the gaps, which will not only cause the surface of the collected fabric to be uneven, but in severe cases, it will even cause the fabric to be entangled in the rotating shaft, causing damage to the machine, which is very dangerous.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example: See Figure 1 The utility model provides a technical solution: a textile rubber roller with adjustable length.

[0028] Among them, the outer surface of the center roller 1 is fixedly connected with wave baffles 13 on both sides, a rotating rod through hole 14 is opened through the center of the center roller 1, a rotating rod 5 is arranged inside the rotating rod through hole 14, a nut 12 is rotatably installed on the fixed screw 11, splicing rollers 2 are arranged on the left and right sides of the center roller 1, a rotating rod through hole 14 is opened horizontally through the center of the splicing roller 2, screw through holes 21 are arranged above and below the rotating rod 5, a fixing screw 11 is arranged inside the upper screw through hole 21, and the left side of the fixing screw 11 is fixedly connected to the center roller 1, a circular countersunk head 22 is opened on the right side of the upper screw through hole 21, a fastener 6 is arranged inside the lower screw through hole 21, and a hexagonal countersunk head 23 is opened on the left side of the lower screw through hole 21.

[0029] In this embodiment, the entire textile rubber roller is a bilaterally symmetrical structure. The surfaces of the center roller 1, the splicing roller 2 and the bottom roller 3 are all provided with wave baffles 13. The wave baffles 13 are in an arc shape. The protrusions and depressions of each wave baffle 13 are semicircular arcs, and the size is consistent, so that the two wave baffles 13 can be completely fitted together, and the center roller 1 and the splicing roller 2 are fitted together through the wave baffles 13. The gap between the two is in a wavy arc shape. In this way, when the rubber roller is winding the fabric, the fine wires on the fabric are not easily stuck in the gap. The number of splicing rollers 2 on both sides of the center roller 1 is increased, so that the length of the entire textile rubber roller is lengthened, thereby adjusting the length of the textile rubber roller, and the nut 12 is screwed into the fixing screw 11 of the center roller 1 to fix the center roller 1 and the splicing roller 2. The screw of the fastener is inserted into the hexagonal countersunk head 23 through the splicing roller 2, and extends out at the circular countersunk head 22 of the other splicing roller 2, and is fixed with the nut of the fastener, thereby locking the two splicing rollers 2.

[0030] Among them, a bottom roller 3 is arranged on the right side of the rightmost splicing roller 2, a fixing groove 31 is opened on the right side of the bottom roller 3, a boss 41 is arranged inside the fixing groove 31, a circular pressure block 4 is fixedly connected to the right side of the boss 41, a rotating rod through hole 14 is opened in the center of the bottom roller 3 and the circular pressure block 4, an external thread is opened on the surface of the rotating rod 5, and an internal thread is opened on the inner side of the circular pressure block 4.

[0031] In this embodiment, after all the splicing rollers 2 are installed, the bottom roller 3 and the circular pressure block 4 are installed. The internal thread on the inner side of the circular pressure block 4 is engaged with the external thread on the surface of the rotating rod 5. The circular pressure block 4 is rotated and pushed on the rotating rod 5. The boss 41 on the circular pressure block 4 is rotated and embedded in the fixing groove 31 on the bottom roller 3. After the bottom roller 3 and the circular pressure block 4 are installed on both ends of the rotating rod 5, the center roller 1 and the splicing roller 2 can be fixed.

[0032] Among them, only the inner side of the bottom roller 3 is fixedly connected with the wave baffle 13.

[0033] In this embodiment, the inner glass baffle 13 and the wave baffle 13 on the splicing roller 2 are fixed by fitting together, and the outer side is fixed by the circular pressing block 4 without the wave baffle 13.

[0034] Among them, one end of the fastener 6 screw is a hexagonal head.

[0035] In this embodiment, the hexagonal head screw is first inserted into the screw through hole 21 with a hexagonal countersunk head 23 on the splicing roller 2 before the splicing roller 2 is installed. The inner wall of the hexagonal countersunk head 23 can fit with the hexagonal head screw, so that the screw cannot rotate. In this way, the two splicing rollers 2 can be locked by rotating the nut of the fastener 6 at the other end.

[0036] Wherein, key slots 51 are formed at both ends of the rotating rod 5 .

[0037] In this embodiment, the key slot 51 facilitates the machine to fix the rotating rod 5 and drives the rotating rod 5 to rotate and reel in the fabric.

[0038] The length of the fastener 6 must be such that it cannot extend from the end surface.

[0039] In this embodiment, the end faces between the two splicing rollers 2 are fitted together, and the fasteners 6 are arranged in a straight line. When the screws of the fasteners 6 extend from the end faces, they will inevitably collide with the fasteners 6 on the other splicing roller 2, making it impossible to install the fasteners 6.

[0040] Working principle: First, pass the rotating rod through hole 14 in the middle of the center roller 1 through the rotating rod 5, and first pass the screw of the fastener 6 through the screw through hole 21 at the hexagonal countersunk head 23 of the splicing roller 2, align the other screw through hole 21 with the fixing screw 21 of the center roller 1, pass through the screw through hole 21 and tighten it with the nut 12, and pass the rotating rod 5 through the rotating rod through hole 14 on the splicing roller 2, and then take a new splicing roller 2 with fasteners installed, and align the other screw through hole 21 with the fastener 6 of the previous splicing roller 2 and screw it with the fastener 5 nut, and so on, install several splicing rollers 2 according to the required length, with the center roller 1 as the center Symmetrically, the bottom roller 3 is installed on one side of the last splicing roller 2, the turning rod 5 passes through the turning rod through-hole 14 on the bottom roller 3, and is fixed with the fastener 6 nut, and then the circular pressing block 4 is rotated and installed. The internal thread inside the circular pressing block 4 is meshed with the external thread on the surface of the turning rod 5, and the turning rod 5 is rotated and pushed forward, and the boss 41 on the circular pressing block 4 is rotated and embedded in the fixing groove 31 on the bottom roller 3. The circular pressing blocks 4 are screwed into both ends of the turning rod 5 to fix the middle center roller 1 and the splicing roller 2. The entire rubber roller is installed. When the length of the rubber roller needs to be adjusted, the bottom roller 3 and the circular pressing block 4 are removed, and the number of splicing rollers 2 can be increased or decreased.
