Description

Technical Field

[0001] The invention relates to the technical field of cigarette packing, and in particular to a paper packing box forming device and a forming process. Background Art

[0002] At present, in the field of cigarette production, multiple cigarettes are usually packaged into a rectangular block collection before delivery. In cigarette packaging, it is often necessary to manually or equipment to arrange the cigarettes on the conveyor belt according to the customer's order, and then convey, stack, seal and package them, and output them. Usually, after sealing, the cigarettes need to be packaged in a packaging box to form a finished product output. Due to the different styles and quantities of cigarettes required by different customers, cigarettes of different styles and quantities need to be mixed and packaged. In order to prevent confusion during transportation, they are packaged into a rectangular block collection through sealing. In this process, due to the limited space utilization of the production workshop, the sealing device and the packaging device are usually separated. The efficiency of transporting by packaging into a rectangular block collection is high and the error rate is low. Therefore, sealing is an indispensable process. In the cigarette shaft engineering, turnover boxes need to be used for turnover. In the past, cartons or non-foldable plastic boxes were usually used to turnover cigarettes. Although cardboard boxes can be folded and stored when not in use, they need to be opened and fixed when needed, which is time-consuming and laborious. Non-foldable plastic boxes, although durable, take up a large space during storage, making the available production space in the production workshop narrow. As a result, the packaging cost of cigarette cartons is increased and the packaging efficiency is reduced.

[0003] The present invention solves the problems caused by the above-mentioned traditional packaging method by optimizing the molding process of the cigarette carton packaging box and improving the cigarette carton packaging box molding device, further reducing the cigarette carton packaging cost and improving the cigarette carton packaging efficiency. Summary of the invention

[0014] 1) Unwind the processed roll of paperboard through the unwinding device, and define the direction extending along the unwinding conveying direction of the paperboard as the longitudinal direction, and the direction extending along its width as the transverse direction;

The two swing rods 71 ​​are driven by the first driving device to swing, so that the two swing rods 71 ​​can move upward and toward each other or downward and oppositely. The swing rods 71 ​​are driven by the first driving device to swing upward toward each other, so that the longitudinal sides of the paperboard are folded longitudinally upward to form a paper packaging box with an opening upward. This structure has good folding effect and high folding efficiency.

[0032] In this embodiment, the output device includes a forming station 11, a packaging station 12 and a transfer device 13 for transferring the paper packaging box in the forming station to the packaging station.
