Description

Technical Field

[0001] The invention relates to the technical field of manufacturing curved offset printing machines, in particular to an assembly robot for manufacturing curved offset printing machines with precise positioning. Background Art

[0002] A curved offset printing press is a special type of printing press used to print on curved objects. This type of printing press can print on curved surfaces such as cylinders, spheres, cones, etc. It is widely used in industries such as flexible packaging, food, beverages, and cosmetics. When a curved offset printing press is manufactured and used, the items to be printed need to be loaded and unloaded.

Since the swing of the push plate will push the baffle to move outward, the binding machine can be bound at different positions on the end cover of the box body, and expand from the middle position of the end cover of the box body to both sides, ensuring that the binding position is symmetrical relative to the middle of the box body, so that the force of the binding machine on the end cover of the box body is symmetrical, so that the sealing between the end cover and the box body is better guaranteed, and the cracks at both ends of the end cover due to uneven force are avoided, and the quality is better. Moreover, the appearance of the binding is relatively symmetrical and beautiful.
