Background

Along with popularization and development of logistics in the tobacco industry, more and more tobacco companies adopt logistics automatic sorting equipment to replace traditional manual cigarette sorting, so that manual operation posts are reduced, labor intensity of staff is reduced, cigarette sorting efficiency is improved, sorting quality of cigarettes is improved, and overall international competitiveness of the tobacco industry is improved.

The paper box packaging specifications of various commodities in the existing market are different, in the automatic sorting process, the paper boxes need to be unpacked, the commodities in the whole box are sent into automatic sorting equipment, and sorting is carried out according to the number and the types of order demands. For example, in the sorting of tobacco streams, it is necessary to unseal the entire box of cigarettes (50 bars/box) of various brands, and place the cigarettes in automated sorting equipment for sorting. After the smoke box enters the conveying link, the first processing link of opening the smoke box is the box drawing, namely the adhesive tape is drawn according to the requirement. Because the cigarette box brands are different, the length, width and height of the cigarette box are different, and in the specified cigarette box size range, the box drawing equipment needs various size cigarette boxes which can be self-adapted, and the adhesive tape of the cigarette boxes is drawn, so that the cigarettes inside the cigarette boxes cannot be damaged, and the specified box drawing efficiency is achieved. The smoke box is packaged by adhesive tape except the outside, and the fly sheets are adhered by glue.

However, tool bit that uses in the present case equipment of drawing, in most supporting and frame through cantilever structure, in the in-process of drawing the case, through stretching out the blade from the knife rest, in order to reach the purpose of drawing the case, but this kind of tool bit mechanism is in the in-process of using, because the stroke of the blade that the cantilever supported is longer, and the blade is softer, make the in-process of drawing the case, the blade appears deformation easily, and to the packing box of different dimensions, required case depth of drawing is also different, and then lead to drawing the case not to prepare, even draw the case and fail, in addition on the letter sorting assembly line, the blade needs quick continuous operation, so the wearing and tearing of blade is more serious, and then need often change the blade, and in current tool bit equipment, the process that the blade was changed is loaded down with trivial details, change time is long, workman intensity of labour is big.
