Description

Bobbin fixing device based on silk fabric textile twisting machine

Technical field

The invention relates to the technical field of textile production, in particular to a bobbin fixing device based on a silk fabric textile twisting machine.

Background technique

In recent years, with the advancement of science and technology and the development of society, China's textile industry has developed rapidly, followed by the rapid development of textile equipment and accessories. In the process of silk production and processing, the silk needs to be twisted and wound on a bobbin. At present, the problem in this process is that due to the relatively small diameter of the silk, this characteristic makes it difficult to control the stability during the winding process, and it is easy to cause relative displacement between the outer silk and the inner silk at the ends of the bobbin. The problem of staggered winding has a serious impact on the later exit and is not conducive to the smooth progress of the textile process.

Patent No. 201720942496.3 discloses a bobbin connecting device for a silk twisting machine for producing anti-wrinkle silk fabric. The bobbin connecting device includes two connecting end covers, and the two connecting end covers are oppositely arranged. The connecting end cover includes End cover body and connection block, the connection block is a flat cylindrical structure, the end cover body is a flat cylindrical structure, the connection block is arranged in the center of the end cover body, and is spaced on the side of the connection block A plurality of elastic strips are provided, and the elastic strips are arranged along the axial direction of the connection block.

The connecting device with the above structure can achieve more firm assembly of the bobbin, and the movable spindle seat drives the bobbin to rotate more stably during the quick start of the twisting machine. In addition, the design of the end cover body can better match the silk at both ends of the bobbin. The position is limited to avoid displacement between the silk in the inner and outer layers of the end, which affects the normal silk output in subsequent processes. However, its disadvantages are: 1. Because the bobbin has various sizes and models, and the above device is designed with only one structure, the fixed model is relatively single, which is not conducive to expanding the scope of use; 2. Although the above device is provided with an end cap body, In order to limit the fixing of silk, there is no structure to protect the silk on the inner surface of the end cap body. Because the end cap is relatively hard, the silk is likely to rub against the end cap body when the silk is wound around the edge of the bobbin. Causes friction damage and seriously affects the quality of later textiles.

Summary of the invention

The technical task of the present invention is to provide a bobbin fixing device based on the silk fabric textile twisting machine in response to the shortcomings in the prior art. The device is provided with rubber bosses of different sizes and can be fixed for bobbins of different models. Moreover, the end cap body is provided with a structure for protecting the thread, which effectively solves the problems that the above-mentioned device has a single fixed tube and cannot protect the thread.

The technical solution adopted by the present invention to solve its technical problem is: the bobbin fixing device based on the silk fabric textile twisting machine has a structure including two connection end caps, and the two connection end caps are oppositely disposed, and the connection end The cover includes an end cover body and a connection component, wherein the connection component includes a first fixing block fixed at the center of the inner surface of the end cover body. The first fixing block is a flat cylinder as a whole. A second fixing block is fixedly located at the center of the surface, and the second fixing block has a flat cylindrical shape as a whole. The first fixing block and the second fixing block are respectively provided with elastic strips on the outer peripheral surface of the second fixing block. The inner surface of the block and the second fixing block are respectively embedded with an annular groove, and a plurality of rubber rods are fixed on the outer wall of the annular groove at intervals. A third fixing block is also fixed at the center of the inner surface of the second fixing block. The fixing block is cylindrical as a whole, and the outer peripheral surface of the third fixing block is fixedly provided with elastic strips at intervals;

A ring-shaped protective cloth piece is bonded to the inner surface of the end cap body by a hook and loop tape, and the protective cloth piece is provided with a notch;

The protective cloth sheet has a composite structure, and includes an internal plastic layer. A polyester fiber layer is provided on the outer side of the plastic layer. A polyester fiber layer is provided on the inner side of the polyester fiber layer. Inside the layer is a denim layer.

Preferably, the diameters of the first fixing block, the second fixing block, and the third fixing block are sequentially reduced from the outside to the inside.

Preferably, the rubber rod is arc-shaped as a whole, and is arranged obliquely toward the inner bottom of the annular groove.

Preferably, the rubber rod is provided with two turns along the circumferential direction of the annular groove.

Preferably, an inner surface of the end cap body is adhered with an adhesive tape base through an adhesive, and a side of the protective cloth piece is adhered with an adhesive tape hook attached with the adhesive tape base through an adhesive.

The invention has the following outstanding beneficial effects:

1. Since the second fixing block is fixed at the center position of the inner surface of the first fixing block, the second fixing block has a flat cylindrical shape as a whole, and the outer peripheral surfaces of the first fixing block and the second fixing block are provided with elasticity at intervals. Strips, the inner surfaces of the first and second fixing blocks are respectively embedded with annular grooves, and the outer wall of the annular groove is fixed with a plurality of rubber rods at intervals. Therefore, when used, the two ends of the bobbin can be sleeved separately. On the outer surface of the first fixing block and the second piece, the elastic strip can play a role of tightening and fixing; the tube can also be clamped in the annular groove, and the rubber rod cooperates with the side wall of the groove to clamp and fix it. To prevent the bobbin from slipping out of the annular groove, it is suitable for the fixing of bobbins of various models and sizes, and it cooperates with the end cap body to avoid the problem of easy displacement of the two ends of the silk, which has a good value for promotion and utilization.

2. Since the third fixing block is also fixed with a third fixing block at the center of the inner surface of the second fixing block, the third fixing block has a cylindrical shape as a whole, and the outer peripheral surface of the third fixing block is fixedly provided with elastic strips at intervals. The third fixing block can be used to fix and fix a relatively small diameter tube, and the elastic strip can play the role of expansion and tightening.

3. Since the inner surface of the end cap body is bonded with a ring-shaped protective cloth sheet through a hook and loop fastener, the protective cloth sheet is provided with a notch. Therefore, during use, the protective cloth sheet can play a role in the silk thread. Good protection prevents direct friction between the silk thread and the end cap body, guarantees the quality of the later textiles, and the stripe notches facilitate the removal, cleaning and replacement of the protective cloth pieces in the later period.

4. Because the protective cloth sheet is a composite structure, including an internal plastic layer, a polyester fiber layer is provided on the outer side of the plastic layer, and a alpha fiber layer is provided on the inner side of the polyester fiber layer. There is a denim fabric layer inside the keratin fiber layer. Therefore, during use, the plastic layer can increase the flatness and strength of the fabric, the polyester fiber layer can increase the flexibility of the fabric, and the alpha fiber layer makes the protective cloth sheet antibacterial and antibacterial. Effect, the denim fabric layer is in contact with silk on the inner surface, which can play the role of abrasion resistance and protection of silk threads.
