Problems solved by technology

The advantages and disadvantages of the slip shaft are obvious, such as the advantages of simple device, less space occupation, and the ability to provide a certain degree of tension control; but it also has certain disadvantages, such as the tension of each roll cannot be independently controlled, and the whole batch must be up and down It is not conducive to convenient refueling, and all strip coils are placed on a through shaft. When a certain coil in the middle is exhausted or has quality problems, all coils must be unloaded to complete the middle. Coil refueling is time-consuming and labor-intensive
[0006] In addition, it is difficult to adjust the strip position when the strip position shifts laterally during transport
When the strips are offset in the transverse direction, the gap between adjacent strips will be too large, or the strips will overlap. Excessive gaps or overlaps between strips will be detrimental to the unidirectional fabric. influences
The method of dealing with strip offset mainly depends on correcting the lateral position of the coil on the unwinding equipment. However, the existing unwinding equipment mainly relies on manually finding and adjusting the position of the coil, which is difficult to achieve effective deviation correction and is time-consuming and laborious.

Abstract

The invention relates to one-way cloth strip unwinding equipment which comprises a rack, a plurality of independent coiled material unwinding devices are arranged on the rack, each coiled material unwinding device is correspondingly provided with a transverse displacement mechanism, the unwinding equipment releases coiled materials to obtain strips, each strip is correspondingly provided with an edge detection device, and the edge detection devices are arranged on the rack. The transverse displacement mechanisms and the edge detection devices are connected with the controller, the edge detection devices send corresponding strip edge position data to the controller, when the controller judges that the strip edge position exceeds a set range, a moving instruction is sent to the corresponding transverse displacement mechanisms, the strip is driven to return to the initial position, and the strip is driven to move. Therefore, the position of the strip is corrected; meanwhile, the independent unwinding equipment can be conveniently replaced when the coiled material is used up or has defects; and the tension control module can prevent the position of the strip from deviating. According to the unidirectional cloth strip unwinding equipment, the quality problem caused by strip deviation in the unidirectional cloth production process can be effectively reduced.

Description

technical field [0001] The invention relates to a unidirectional strip unwinding device, in particular to a strip unwinding device equipped with a cooperative deviation correction system. Background technique [0002] In order to quickly disperse ballistic impact stress waves, high-performance composite materials for bulletproof mostly adopt the structure of non-woven fabrics, which are composed of two or more layers of unidirectional fabrics cross-composited. [0003] Among them, unidirectional fabric refers to a large number of woven yarns or rovings in one direction (usually warp direction, but also weft direction unidirectional fabric), and no or only a small amount of and usually fine yarn in the other direction. A textile whose strength is all in one direction. [0004] There are two main forms of ultra-high molecular weight polyethylene materials used in the bulletproof field, one is in the form of fibers, and the other is in the form of strips. The production proce...
