Description

Accelerated conveying device for automatic leveling and shaping collection system of cigarette cartons

Technical field

The invention relates to the technical field of recycling of cigarette strips and wrappers, and in particular to an accelerated conveying device for an automatic leveling and shaping collection system for cigarette strips and wrappers.

Background technique

In the production process of hand-sealed cigarette cartons, most cigarette factories use packaging machines to produce standard packets. When packaging cigarette cartons, they use white box skin without glue and use transparent paper for outer packaging. When hand-sealing cigarette cartons, When stripping the boxes, remove the white box skins and collect them. In order to save costs, white box skins are generally recycled for two or three times. However, because the used strip box skins have already gone through a packaging process on the packaging machine, the white box skins are deformed and difficult to use again, so they are difficult to use for the second time. Leveling must be done before.

As for the leveling of white box leather, there is currently no special equipment available. Although there are some paper flattening equipment, they are not suitable for flattening the deformed white box skin.

For example, the utility model patent CN207986272U discloses a paper flattening device for a cigarette box printing production line. It is provided with a threaded column and a first fixed block, and a connecting rod is hingedly connected to the first fixed block. The other end of the connecting rod They are all hinged with fixed blocks. When the disc handwheel is turned, the mounting plate at the bottom of the fixed block is lowered, thereby compressing the paper. A threaded rod and a drive motor are provided in the mounting plate. When the drive motor works, the threads The second movable block on the rod moves horizontally, which facilitates the pressure roller to press back and forth on the paper, making the paper smoother. By placing an electric heating tube horizontally in the installation cavity of the workbench, the paper is flattened at the same time. Heating facilitates the transfer of graphics and text to the paper when printing the cigarette box.

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

Currently, in response to the objective demand for the recycling of white box skins in the production process of hand-sealed cigarette cartons, manual sorting and gravity flattening have been used, which takes a long time and wastes manpower, and is inconsistent with the industry's concept of cost reduction and efficiency improvement.

They are parallel to each other to facilitate subsequent processing. The cooperation of the three can automatically take out a single box skin from the material warehouse according to the production rhythm and place it on the conveying structure to achieve step-by-step intermittent conveying.

The magazine 11 includes a magazine frame 111 and a material guide structure located inside the magazine frame 111. The material guide structure is composed of a magazine side plate 112 corresponding to the side of the box skin and a magazine corner plate 113 corresponding to the top corner of the box skin. The storage side plate 112 and the storage corner plate 113 are both fixedly connected to the storage frame 111.
