On the carding machine, as the weaving process progresses, the woven fabric must be taken out from the opening at any time and wound onto the brocade. At the same time, the appropriate length of warp yarns must be superimposed on the weaving shaft to ensure that the warp and weft yarns can be continuously at the loom. intertwined. Special equipment for the textile industry on the winder. As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field.
Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery. According to the spinning process, carding is an important process. The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process).
During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine. The movement of pulling the fabric out of the opening at a certain speed and winding to the drum t is called the winding movement, and the movement of stacking the warp yarns of the corresponding length from the weaving uranium is called the moving movement. The take-up and let-off operations are carried out on the loom by the take-up and let-off mechanism.
There are many types of take-up and let-off mechanisms in carding machinery. Here, we mainly introduce the take-up and let-off mechanisms used in new looms manufactured by imported technology in recent years, and introduce the process calculation of take-up and let-off. The function of the control movement of the carding machine winding is to lead the formed fabric away from the weaving fell, and wind it into a certain winding system form. At the same time, the weft density of the research fabric can be adjusted by adjusting and the size of the fabric pull-out speed.
The main types of rewinding mechanisms of carding machines are as follows: The research on the winding effect of fabrics by intermittent reeling mechanism occurs periodically in a certain development period during the rotation of the main shaft of the loom. The management of this kind of coiling mechanism is relatively simple, and it is convenient to adjust itself, but there is a huge impact during coiling, the parts wear quickly, and it is prone to loosening, which leads to market failure. The technology is widely used on shuttle looms. Overturn the ground.
The advantages of this type of coiling mechanism are that the coiling movement is stable, without impact, and the machine parts are lightly worn, but the structure is relatively complex, which is more common in various new looms. In addition, the electronic winding mechanism has been used on the new loom.
