technical field

This article relates to, but is not limited to, the technical field of keel bonding, especially but not limited to a method and device for side keel bonding.

Background technique

Compared with the ordinary keel, the side keel is an irregular keel, and the heights of the left and right sides of the keel are different and relatively narrow. Therefore, the packaging and transportation of the side keel is very cumbersome and takes up a lot of manpower and material resources.

The side-bones splicing machine is a device that folds the side-bones of the two openings in the same direction, and completes the stitching function of the side-bones. The side keels after stitching are regular geometric bodies, which are convenient for packaging and transportation. However, most of the laminating machines used in the production line are single linkage, and it is difficult to maintain the consistency and simultaneity of the flipping action. The success rate of flipping the lid is not high; manual intervention is required in the process, and after the side keels are joined, due to the different heights of the left and right sides of the side keels, they are very easy to fall apart during automatic transportation (as shown in Figure 11). As a result, the production cost is high; the production efficiency is low.
