Description

Technical Field

[0001] The utility model relates to the technical field of cigarette box printing, in particular to a paper flattening device for a cigarette box printing production line. Background Art

[0002] Cigarette box printing is used as cigarette box packaging to highlight its own characteristics, which can make the product stand out in the market of many similar commodities and improve the recognition of the product. The manufacturing material of cigarette boxes is generally paper. The production of cigarette boxes is carried out by printing the corresponding brand, type and other information on the paper. During the printing process of cigarette box paper, in order to ensure the quality of the cigarette box, the paper needs to be flattened.

[0003] The patent document with announcement number CN220700691U discloses a paper flattening device for a cigarette box printing production line, including a paper flattening device body, a mounting block fixedly installed above a fixed component, a flattening groove provided inside the mounting block, a connecting column fixedly installed below the flattening groove, a second connecting plate fixedly installed below the connecting column, a fixed wheel rotatably connected below the second connecting plate, a placement plate provided below the fixed wheel, by placing paper above the placement plate to shrink the connecting column, push the placement plate in, extend the connecting rod to drive the second connecting plate down so that the fixed wheel fixes the paper, the control panel controls the drying box to heat up the upper paper environment, to avoid excessive humidity due to environmental influences to generate static electricity, to absorb floating dust, and to affect subsequent processing, and at the same time, the edges and corners of the fixed wheel are flattened when the paper is pulled out, effectively reducing labor costs, but the prior art still has defects:

[0004] (1) In the prior art, the paper flattening device drives the second connecting plate to descend through the connecting column so that the fixing wheel fixes the paper. Since the connecting column is fixedly arranged below the flattening groove, it is not convenient to adjust the distance between the second connecting plates, so that the device cannot adapt to papers of different sizes, reducing the application range of the device.

[0005] (2) In the prior art, when flattening paper, the paper is placed on a corresponding work platform, fixed by a flattening roller and other facilities, and then the placement plate is pulled out, and the flattening roller is rolled to squeeze and flatten the paper. However, the hard squeezing of the paper by the flattening roller is likely to cause damage to the paper due to excessive squeezing. At the same time, the placement plate needs to be manually pulled out, which is time-consuming and labor-intensive, and it is difficult to control the pulling speed. The paper is easily unevenly stressed due to reasons such as the rolling speed, which affects the final production effect, the flattening effect is not good, and the work efficiency is reduced.
