Description

Technical Field

[0001] This utility model belongs to the field of inner liner paper production technology, and more specifically, it relates to a paper receiving device for a flexographic printing machine. Background Technology

[0002] Cigarette production is divided into two main parts: the cigarette body and the cigarette box. The cigarette box consists of a cardboard box and an inner liner. The inner liner requires a flexographic printing process. The inner liner is fed into the flexographic printing machine, where the printing parts print on it. After printing, the inner liner is wound up by the paper take-up device on the flexographic printing machine.

[0003] According to CN202320350895.6, this utility model relates to the field of winding equipment technology and discloses a flexographic printing winding device, including a paper pressing device. A pressing device is fixedly connected to the top of the paper pressing device, and a base is fixedly connected to the top of the pressing device. A rotating device is fixedly connected to the rear side of the base, and a fixing device is fixedly connected to the outer side of the rotating device. A controller is fixedly connected to one side of the front side of the base, and a fixing plate is placed on the other side of the front side of the base. A pin is movably connected to the front side of the fixing plate, and a drying device is movably connected inside the base. This utility model, by providing a fixing device, can fix paper tubes of different lengths, thereby enabling it to wind printed materials of different widths, making it highly practical. The drying device allows the printed materials to be dried, ensuring that the ink on them becomes drier and preventing sticking due to undried ink.

[0004] Based on the above, existing paper receiving devices generally adopt a rotary shaft winding structure. When the staff takes the paper, they need to first remove the rotary shaft and then carry the rolled inner liner paper off the rotary shaft. However, the rolled inner liner paper is relatively heavy, which makes it difficult for the staff to carry and remove it, thus affecting the staff's use of the paper receiving device.

[0015] This invention employs a paper take-up and take-up mechanism that connects two sets of paper take-up slides together. The rolled-up inner liner paper is placed on the outer end face of the two sets of paper take-up slides. The winding motor drives the paper take-up slides and the rolled-up inner liner paper to rotate, facilitating the winding of the inner liner paper. When the rolled-up inner liner paper is removed from the paper take-up slides, the operator uses a tool to twist the starting block to rotate. The rotation of the starting block causes the paper take-up slides to slide. The paper take-up slides are hidden inside the winding connecting shaft, so that the rolled-up inner liner paper automatically falls onto the support base, avoiding the problem of requiring the operator to move the rolled-up inner liner paper.

[0016] This utility model employs a release and support mechanism, which enables the lifting motor to drive the support base to slide and lift, and the support base to drive the rolled inner liner paper to lift and lift. The movable rollers facilitate the movement of the rolled inner liner paper, avoiding the problem of workers carrying the rolled inner liner paper and making it convenient for workers to use the paper receiving device.
