Description

A kind of cigarette rod casing recycling method

technical field

The invention relates to the technical field of cigarette rod casing recycling, in particular to a cigarette rod casing recycling method.

Background technique

In the production process of hand-sealed cigarette packs, most cigarette factories use standard small packs produced by packaging machines to pack cigarettes with white box skins without dispensing glue and wrap transparent paper for outer packaging. When the box is opened, the white box skin is disassembled and collected. In order to save costs, the white box skin is generally used twice or three times in a cycle, but the used carton skin has already undergone a packaging process on the packaging machine, and the deformation of the white box skin is difficult to use again. must be leveled before.

For the leveling of white box skins, there is currently no special equipment available. Although there are some paper flattening devices, they are not suitable for flattening the white box skin after deformation.

For example, the utility model patent of CN207986272U discloses a paper flattening device for a cigarette case printing production line, which is provided with a threaded column and a first fixing block, and a connecting rod is hinged on the first fixing block, and the other end of the connecting rod is connected. Both are hinged with a fixed block. When the disc handwheel is rotated, the mounting plate at the bottom of the fixed block is lowered, so as to realize the pressing of the paper. By installing a threaded rod and a driving motor in the mounting plate, when the driving motor works, the thread The second movable block on the rod moves horizontally, which is convenient for the pressing roller to press back and forth on the paper, so that the paper leveling effect is better. Heating, it is convenient for the cigarette case to transfer the pictures and texts to the paper during printing.

The flattening equipment is only suitable for flattening the rolled paper before the cigarette case is formed, and the existing flattening equipment is difficult to meet the flattening requirements due to the deformation and creases on the white box skin after use.

At present, in view of the objective demand for the recycling of white box skins in the production process of hand-sealed cigarette boxes, manual sorting and gravity flattening have been used all the time, which takes a long time and wastes manpower, which is inconsistent with the industry's concept of reducing costs and increasing efficiency.
