Ivory board safety line positioning device

Abstract

The invention discloses an ivory board safety line positioning device which comprises a fixing base. An installing cavity is formed in the fixing base, the top of the fixing base is provided with an installing hole, the installing hole is communicated with the installing cavity, a lead screw is rotatably installed in the installing hole, two ends of the lead screw extend out of the installing hole, multiple installing seats are arranged in the installing cavity at intervals, the top of the installing base is provided with a screw hole, a round groove is formed in the inner wall of the bottom of the installing cavity, the bottom end of the lead screw sequentially penetrates through multiple screw holes and is rotatably installed in the round groove, the multiple screw holes are in threadedconnection with the lead screw, multiple through holes are formed in one side of the fixing base at intervals and are communicated with the installing cavity. The ivory board safety line positioning device is simple in structure, convenient to use, capable of conveniently and quickly positioning an ivory board safety line and avoiding the phenomenon that safety line position change of an ivory board in the moving process causes that a safety line on the ivory board cannot be further processed.

Description

technical field [0001] The invention relates to the technical field of white cardboard production, in particular to a white cardboard safety line positioning device. Background technique [0002] At present, imported white cardboard occupies a considerable market share in the domestic market, but domestic white cardboard has the potential to squeeze this part of the market. After China joined the WTO, although the import tax rate of white cardboard decreased, the absolute amount of import tax was still relatively high because white cardboard is high-value paper. It is zero, and domestic white cardboard still has certain advantages in price. [0003] White cardboard usually needs to be nested with security thread in the manufacturing process, so as to achieve the effect of security and anti-counterfeiting. After searching, the patent document with publication number CN105507079A discloses a production process of a new type of security thread anti-counterfeiting paper. The pr...

Problems solved by technology

The security thread anti-counterfeiting paper does not contain plastic security thread and plastic materials such as surface coating or composite film, which overcomes the defect that the security thread anti-counterfeiting paper is easy to curl, but in actual use, when the security thread is embedded in white cardboard, it is still It needs to go through aluminizing, compounding, peeling transfer, varnish, edge separation, slitting and other processes. When the white cardboard is further processed, the white cardboard needs to be moved. During the movement of the white cardboard, the safety line is on the white cardboard. It is easy to translocate inside, which leads to the failure of normal further processing of the safety thread. Therefore, a white cardboard safety thread positioning device is proposed.
