A device for preventing unraveling of multiple paper rolls

Abstract

The invention discloses a multi-strip paper roll roll-loosening-preventing device which comprises a base, a front guide rail and a back guide rail. The front guide rail and the back guide rail are arranged on the base in parallel, a plurality of movable pressing plate mechanisms are movably installed on the front guide rail, and air cylinder supporting mechanisms are movably installed at the positions, corresponding to the movable pressing plate mechanisms, of the back guide rail; and the air cylinder supporting mechanisms are hinged to the back portions of the movable pressing plate mechanisms, the movable pressing plate mechanisms are controlled by air cylinders to rotate, and therefore the upper surfaces of the movable pressing plate mechanisms press paper rolls all the like, and the paper rolls are prevented from loosening. By means of the provided multi-strip paper roll roll-loosening-preventing device, uniform pressing on multiple paper rolls is achieved, the degree of tightness of interleaving paper is guaranteed, and the roll loosening condition is prevented.

Description

technical field [0001] The patent of the present invention relates to an auxiliary device for a slitting machine, in particular to a device for preventing unraveling of multiple rolls of paper that is applied on a slitting machine to press the backing paper. Background technique [0002] The slitting machine is a kind of equipment for longitudinal cutting of wide roll materials. In the field of stainless steel strip processing, the rolled stainless steel strip will be cut into strips according to customer needs and then rewound. When rewinding, two layers of stainless steel A layer of backing paper needs to be added between the strips to protect the surface of the strip. Generally, the backing paper roll is set at the tail of the slitting machine, and the backing paper is fed from the back to the front. Because the strip will be cut into different widths according to requirements Size, which requires the increased width of the backing paper to be consistent, and the winding ...

Problems solved by technology

[0003] However, this brings about a problem. Since there is no pressing structure on the backing paper frame, different backing paper rolls have different elasticities when they are fed in, so that the backing paper rolls appear to be unrolled, resulting in a gap between the strips. If the backing paper is wrinkled, the most common way is to manually press it to prevent the backing paper roll from loosening. The pressing pressure of individuals is different, and this situation still exists more or less
