Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of fabric production and processing, in particular to a novel double-layer untwisting roller device. BACKGROUND
[0002] In the field of textile industry, the twist of fabric is significantly increased after a series of processes such as spinning, weaving and subsequent chemical treatment. At this time, in order to meet the requirements of the subsequent processing flow on the flatness and fiber structure of the fabric, the fabric must be untwisted. This process is directly related to product quality and production efficiency. With the continuous innovation of textile technology, the processing demand for light and thin fabric is growing rapidly. Extremely thin fabric encounters many challenges in the untwisting process due to its own light and thin material and unique structure.
[0003] The common untwisting approach is to rely on the swing of the untwisting roller to complete the untwisting operation of the fabric. When processing conventional thickness fabric, this method is effective. However, for extremely thin fabric, it is extremely difficult to stay stable in the middle of the two rollers due to its light weight and poor rigidity. During the swing of the untwisting roller, the extremely thin fabric is prone to deviation and sliding, which not only seriously interferes with the continuity and stability of the untwisting process, but also causes uneven twist, fabric damage and other problems, thereby reducing product quality and increasing production cost. In order to limit the position of the fabric during untwisting, ensure the continuity and stability of the untwisting process, and avoid problems such as uneven twist and fabric damage, we propose a novel double-layer untwisting roller device.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0022] Please refer to Figures 1-4 The utility model provides a technical scheme: a novel double-layer untwisting roller device, including bottom plate 1, bottom plate 1 is fixedly connected with connecting frame 2 outside, connecting frame 2 top is fixedly connected with top plate 4, top plate 4 is set with discharge port 5, bottom plate 1 is rotatably provided with feeding cylinder 3, feeding cylinder 3 is fixedly covered with swing wheel 11 outside, swing wheel 11 top is fixedly installed with second mounting bracket 12, second mounting bracket 12 is rotatably installed with two groups of straight rollers 17, and the two groups of straight rollers 17 are arranged in 90 degrees staggered between the two groups of straight rollers 17, and two groups of inner recess rollers 16 corresponding to the straight rollers 17 are arranged on the second mounting bracket 12.
[0023] Corresponding inner recess roller 16 and straight roller 17 are combined to form untwisting roller, the fabric needing to be untwisted enters from feeding cylinder 3, passes through between inner recess roller 16 and straight roller 17, and inner recess roller 16 and straight roller 17 clamp the fabric, swing wheel 11 swings and drives second mounting bracket 12 to swing, so that inner recess roller 16 and straight roller 17 swing, thereby the fabric clamped between inner recess roller 16 and straight roller 17 is untwisted, since the two groups of untwisting rollers are arranged in 90 degrees staggered, the position of the fabric is limited by the two groups of untwisting rollers in the swinging process, so that the fabric always stays in the middle position of inner recess roller 16 and straight roller 17 and cannot deviate or fall off, thereby the position of the fabric is limited during untwisting, the coherence and stability of the untwisting process are ensured, and problems such as uneven twist and fabric damage are avoided.
[0024] Both ends of the straight roller 17 are rotatably connected to the first connecting block 18, and both ends of the concave roller 16 are rotatably connected to the second connecting block 20. A spring 19 is fixedly installed between the first connecting block 18 and the second connecting block 20. Several sets of movable openings 21 matching the concave roller 16 are opened on the second mounting frame 12, and the concave roller 16 is movably connected to the movable openings 21.
[0025] The spring 19 can ensure the clamping force between the concave roller 16 and the straight roller 17 while making the position of the concave roller 16 adjustable, so as to adapt to fabrics of different thicknesses.
[0026] The first connecting block 18 is fixedly connected to the second mounting bracket 12 on the side closest to the second mounting bracket 12.
[0027] The second connecting block 20 is slidably connected to the second mounting bracket 12 on the side near the second mounting bracket 12.
[0028] This ensures that neither the first connecting block 18 nor the second connecting block 20 will rotate, thus ensuring the stability of the spring 19 connection.
[0029] A first mounting bracket 6 is fixedly connected to the top of the base plate 1. A motor 7 is fixedly mounted on the top of the first mounting bracket 6. A drive wheel 15 is fixedly connected to the output end of the motor 7. A belt is tensioned between the drive wheel 15 and the swing wheel 11.
[0030] The start motor 7 drives the drive wheel 15 to rotate back and forth, and the swing wheel 11 swings through the belt.
[0031] A first connecting frame 8 is fixedly connected to the inner wall of the connecting frame 2. Two sets of mounting plates 9 are fixedly installed on the first connecting frame 8. A fabric clamping roller 10 is rotatably installed on the mounting plate 9.
[0032] A second connecting frame 13 is fixedly connected to the inner wall of the connecting frame 2, and a guide roller 14 is rotatably mounted on the second connecting frame 13.
[0033] The untwisted fabric is spread out and passed between two sets of clamping rollers 10, then reversed by guide roller 14, and finally exited from the discharge port 5 for collection, completing the entire untwisting process.
[0034] Working principle: The concave roller 16 and the straight roller 17 are combined to form a detwisting roller. The fabric to be detwisted enters from the feed cylinder 3 and passes between the concave roller 16 and the straight roller 17. The concave roller 16 and the straight roller 17 clamp the fabric. The spring 19 can ensure the clamping force between the concave roller 16 and the straight roller 17 while making the position of the concave roller 16 adjustable, so as to adapt to fabrics of different thicknesses. The starter motor 7 drives the drive wheel 15 to rotate reciprocally, causing the swing wheel 11 to swing via a belt. This swings the second mounting frame 12, causing the concave roller 16 and the straight roller 17 to swing, thereby untwisting the fabric sandwiched between them. Because the two sets of untwisting rollers are staggered at 90 degrees, they mutually restrict the position of the fabric during the swing, ensuring that the fabric remains in the middle position between the concave roller 16 and the straight roller 17, preventing it from shifting or falling off. This restricts the position of the fabric during untwisting, ensuring the continuity and stability of the untwisting process and avoiding problems such as uneven twist and fabric damage. The untwisted fabric is then spread out and passed between the two sets of clamping rollers 10, then reversed by the guide roller 14, and finally exited from the discharge port 5 for collection, completing the entire untwisting process.
