Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of carton printing, in particular to a mechanism for adjusting the height of the corner-cutting box in the forming part of a carton printing and forming production line. Background Technique
[0002] In the printing, slotting and processing of cardboard for carton packaging, it is necessary to perform slotting, corner-cutting and edge-cutting on the printed cardboard. When performing slotting and corner-cutting, each slot or corner-cut is completed by two slotting knives or a slotting knife and a corner-cutting knife with a certain relative position. Because in the process of carton processing, the sizes of the processed cartons are different, and the height dimensions of the cartons and the depths of the slots are also inconsistent. Therefore, it is necessary to adjust the relative positions of the two knives to achieve slotting and corner-cutting of cardboard with different sizes.
[0003] In the traditional carton printing and forming production line, the inner gear is connected to the rear corner-cutting knife, making it inconvenient to adjust the height of the corner-cutting box and resulting in low forming stability. Content of the Utility Model
[0004] The purpose of the utility model is to provide a mechanism for adjusting the height of the corner-cutting box in the forming 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 mechanism for adjusting the height of the corner-cutting box in the forming part of a carton printing and forming production line, including a paper feeding unit, a printing unit, a forming unit and a die-cutting unit. Among them, the forming unit is provided with a mechanism for adjusting the height of the corner-cutting box. The mechanism for adjusting the height of the corner-cutting box includes an adjustment shaft and an upper shaft, and the adjustment shaft and the upper shaft are arranged in parallel. A small gear is fixedly sleeved on the adjustment shaft, and a large gear is fixedly sleeved on the upper shaft, and the large gear meshes with the small gear;
[0006] A rear corner-cutting knife is fixedly installed on one side of the large gear, and a wheel core is fixedly connected to the large gear. A pre-pressing upper wheel is fixedly sleeved on the wheel core, and a front corner-cutting knife is fixedly installed on the wheel core.
[0007] Preferably, the rear corner-cutting knife is fixed to the large gear by screws.
[0008] Preferably, the wheel core is sleeved on the upper shaft.
[0009] Preferably, one end of the adjustment shaft is connected to the output end of a motor.
[0010] Preferably, the rear corner-cutting knife is located between the large gear and the pre-pressing upper wheel.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] The post-cutting knife is fixed on the large gear. Compared with the previous connection of the post-cutting knife to the internal gear, it is more convenient to adjust, thus achieving higher forming stability and improving production efficiency and quality. Brief Description of the Drawings

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0017] Please refer to Figure 1-2 , the present utility model provides a technical solution: a corner-cutting box height adjustable mechanism for the forming part of a carton printing and forming production line, including a paper feeding unit, a printing unit, a forming unit, and a die-cutting unit. Among them, the forming unit is provided with a corner-cutting box height adjustable mechanism, and the corner-cutting box height adjustable mechanism includes an adjustment shaft 2 and an upper shaft 4, and the adjustment shaft 2 and the upper shaft 4 are arranged in parallel. A pinion 3 is fixedly sleeved on the adjustment shaft 2, and a large gear 5 is fixedly sleeved on the upper shaft 4, and the large gear 5 meshes with the pinion 3;
[0018] A post-cutting knife 6 is fixedly installed on one side of the large gear 5, and a wheel core 9 is fixedly connected to the large gear 5. A pre-pressing upper wheel 8 is fixedly sleeved on the wheel core 9, and a pre-cutting knife 7 is fixedly installed on the wheel core 9.
