Description

Technical Field

[0001] The utility model relates to the technical field of carton printing, in particular to a polygonal structure of a bellows lip plate in a printing part of a carton printing and forming production line. Background Technique

[0002] During the automatic processing of paper boxes, after the side paper and the inner cardboard of the packaging box are folded, the bottom paper is then pressed against the bottom of the inner cardboard. Then, the sticker die adsorbs the bottom paper and applies glue to the bottom paper, and the bottom paper is pasted to the bottom of the side paper of the packaging box corresponding to the outside of the bottom paper. When the paper box is being processed, before the sticker die adsorbs the bottom paper, the bottom paper needs to be conveyed to the sticker die through a paper feeding mechanism, and then it is convenient to process the cardboard to improve production efficiency.

[0003] Currently, during the high-speed operation of a carton printing and forming production line in paper feeding, printing, slotting, die cutting, etc., the paper feeding mechanism is conveyed through a suction box. The traditional suction box has few suction angles and unstable adsorption of cardboard, affecting production efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a polygonal structure of a bellows lip plate in a printing part of a carton printing and forming production line to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A polygonal structure of a bellows lip plate in a printing part of a carton printing and forming production line, including a paper feeding unit, a printing unit, a slotting unit, and a die cutting unit. Among them, the bellows lip plate of the printing unit is provided with a polygonal structure. The polygonal structure includes a suction box, and a lip plate is installed on the top of the suction box. A plurality of equidistant polygonal suction openings are opened on the lip plate.

[0006] Preferably, the top of the suction box is open, and the lip plate is fixedly installed at the open position of the top of the suction box.

[0007] Preferably, the suction box is of a rectangular structure.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] Compared with a square lip plate, the polygonal lip plate sucks air from multiple angles, has more stress points, stably adsorbs the cardboard, makes the cardboard transmission smoother, and improves production efficiency and production quality. Description of the Drawings

[0012] Next, in combination with the drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0013] Please refer to Figure 1 , the present utility model provides a technical solution: a polygonal structure of the air box lip plate in the printing part of a carton printing and forming production line, including a paper feeding unit, a printing unit, a slotting unit, and a die-cutting unit. Among them, the air box lip plate of the printing unit is provided with a polygonal structure, and the polygonal structure includes an air suction box 1, and a lip plate 2 is installed on the top of the air suction box 1, and a plurality of equally spaced polygonal air suction openings 3 are opened on the lip plate 2.

[0014] In the present utility model, the top of the air suction box 1 is open, and the lip plate 2 is fixedly installed at the opening position at the top of the air suction box 1.

[0015] In the present utility model, the air suction box 1 is of a rectangular structure.

[0016] The working principle of the present utility model: The lip plate 2 is installed on the air suction box 1, and a plurality of equally spaced polygonal air suction openings 3 are opened on the lip plate 2. When the printed cardboard is conveyed here, it is sucked through the air suction openings 3. The polygonal structure adsorbs the cardboard stably, better ensuring the transmission of the cardboard and the delicacy of printing, with higher efficiency.

[0017] The content not detailedly described in this specification belongs to the prior art well-known to those skilled in the art. Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
