Background

The quality of finished cigarette packages in tobacco enterprises is an important factor related to the quality of cigarettes, and the detection of the quality of the packages is one of the key links for controlling the quality of the cigarettes. In the production process of the carton cigarette, a layer of transparent packing paper is wrapped outside the packing box so as to achieve the effects of sealing and moisture prevention. In order to facilitate the user to unpack the package, a pull line with the width of about 2-3mm is attached to the inner surface of the transparent packing paper. The pulling wire may have the problems of loss, deviation and the like, and the transparent paper gap may also have dislocation, thereby seriously affecting the quality of the cigarette carton. The traditional detection method is that the cigarette carton produced by each packer is intensively detected before a packer, and because the deviation condition of the transparent paper wiring of the cigarette carton produced by each packer is different and is within the quality allowable range, the accumulated deviation is very large, the setting of the cigarette carton detector is inevitably difficult, the detection difficulty is increased, the detection precision is difficult to guarantee, and if the deviation cannot be found in time, the cigarette packet with the problem in the packing is caused to flow into the market, and the reputation of a cigarette factory is seriously influenced. To this problem, many cigarette factories have adopted the installation strip outward appearance detection device on ZB45 packagine machine, but most of schemes need the stayguy of strip package just can carry out correct detection in one side for some certified products are regarded as the defective work by mistake because of stayguy is at the opposite side, increase cost, and can only detect whether the stayguy of strip cigarette one side goes wrong, probably leak the defective work that has the stayguy and other directions are lacked just bottom.
