Roller body clamping structure for packaging film production

Abstract

The invention discloses a roller body clamping structure for packaging film production. The roller body clamping structure comprises two racks, a rotary shaft arranged between the two racks and a roller body arranged on the middle portion of the rotary shaft in a sleeving mode. The roller body clamping structure is characterized in that the racks are both provided with clamping structures for mounting the rotary shaft; each clamping structure comprises a clamping block hinged to the rear side of the upper end of the corresponding rack; the middles of the lower ends of the clamping blocks and the middles of the upper ends of the racks are all provided with semicircular grooves matched with the rotary shaft. the front end of each clamping block is provided with a convex block extending forwards; the front ends of the convex blocks and the front ends of the racks are all provided with matched containing grooves; each containing groove is formed in the up-down direction and the front end of the containing groove is provided with an opening. The roller body clamping structure is provided with the clamping structures and limiting devices, the mounting and demounting speed of the roller body is greatly increased; the printing time consumed during shutdown is reduced; the production efficiency is improved; and the roller body clamping structure is high in stability and wide in application range.

Description

technical field [0001] The invention relates to the field of packaging film production equipment, in particular to a roller body clamping structure in the production of packaging film. Background technique [0002] Plastic bags are used more and more frequently in packaging, and in order to achieve the aesthetic performance of plastic belts, patterns need to be printed and dyed on plastic bags. The plastic bag pattern is generally dyed on the unformed packaging film using a packaging film color printing machine. [0003] Existing packaging film color printing machines often use a large number of sticks, such as feeding rollers, receiving rollers, pressure rollers or guide rollers. The installation of these sticks is generally fixed, which is extremely inconvenient for replacement or maintenance. It takes up the printing time of the printing machine and reduces the production efficiency. Contents of the invention [0004] The object of the present invention is to provide ...
