A line-stitched carton automatic packaging production line

Abstract

The invention discloses an automatic packaging production line for a thread stitching type carton. Three side paper boards, a bottom paper board and a cover paper board are spliced to be in the shapematched with that of a cross-shaped groove, the paper boards needing to be stitched with threads are transported to the position between two pressure bearing plates and under a top plate through a conveying mechanism, the three side paper boards, the bottom paper board and the cover paper board can be pressed by starting a pressing mechanism, the condition that the paper boards are prone to risingand falling in the stitching process, and then the thread stitching process is influenced is reduced, excessive thread ends are cut, manual plugging operation is not needed, the safety is improved, and the convenience is improved; a conveyer belt conveying mode is adopted, people only need to assemble the paper boards needing to be stitched together, the manual operation steps are reduced, time and labor are saved in the operation process, therefore, the working efficiency is improved, and the production efficiency is improved; and the stitching paper boards can be pressed through the pressing mechanism, therefore, the paper boards do not generate the rising and falling process, and the stitching process becomes more fluent.

Description

technical field [0001] The invention relates to a packaging production line, in particular to a thread-stitched carton automatic packaging production line. Background technique [0002] Carton: It is the most widely used packaging product. According to different materials, there are corrugated cartons, single-layer cardboard boxes, etc., with various specifications and models. Cartons are commonly used with three layers and five layers, and seven layers are rarely used. Each layer is divided into lining paper, corrugated paper, core paper, and face paper. The color and feel are different, and the paper (color, feel) produced by different manufacturers is also different. [0003] The inner bottom of the carton mainly bears heavy objects. Therefore, the carton production line needs to connect the bottom of the carton with the adjacent side by seaming, so as to strengthen the connection between the bottom and the side of the carton, thereby improving the load-bearing capacity ...

AI Technical Summary

Problems solved by technology

[0003] The inner bottom surface of the carton is the bottom surface that mainly bears heavy objects. Therefore, the carton production line needs to stitch the bottom surface of the carton to the adjacent side surface to strengthen the firmness of the connection between the bottom surface and the side surface of the carton, thereby improving the load-bearing capacity of the bottom surface. The existing processing production line is The bottom and side of the carton can only be connected by single-thread suture, and its firmness is relatively low. After the suture is completed, it needs to be cut manually. The manual operation process is time-consuming and laborious, and the machine is always running. dangerous
