Description

TECHNICAL FIELD

[0001] The present application relates to the field of film shearing, in particular to a film shearing assembly. BACKGROUND

[0002] In the printing field, the film coating process is an important means to improve the quality of the printing material (such as paper, film, etc.), and the printing material treated by film coating can enhance the gloss, wear resistance and water resistance, and is widely used in bookbinding, commodity packaging and other scenes. As a key process after film coating, the precision of shearing directly determines the specifications and quality of the product.

[0003] At present, when shearing the printing material after film coating, due to the flexible nature of the printing material itself, the two sides disconnected in the cutting moment are prone to position deviation due to uneven stress or elastic deformation. If the deviation is large, it will not only cause shearing size error, damage the flatness and aesthetics of the film coating surface, but also cause difficulty in matching subsequent processing (such as binding, packaging assembly), and greatly increase the scrap rate. The existing shearing equipment mostly adopts the basic fixed and cutting mode, lacks a targeted control mechanism for the flexible deviation of the printing material, and cannot accurately solve the deviation problem after cutting, thereby affecting the overall shearing effect and production efficiency.

[0004] For the related technologies in the above, the inventors believe that the printing material has the defect of position deviation affecting the shearing effect when shearing after film coating, and therefore propose a film shearing assembly to solve the above problems. CONTENT OF THE INVENTION

[0009] Preferably, the width of the two ends of the movable supporting plate is less than the distance between the two ends of the inner wall of the fixed long groove, and the outer surface of the movable supporting plate is located in the fixed long groove.

[0010] Preferably, the upper surface of the rack plate is movably located near the bottom of the outer surface of the gear, and the gear and the rack plate are in meshing engagement.
