A roller position adjustment device in the production of packaging film

Abstract

The invention discloses a roller position adjusting device in packaging film production. The roller position adjusting device comprises a machine frame and a slide way, wherein the slide way is arranged on the machine frame and is horizontally arranged; the roller position adjusting device is characterized in that two positioning fixing plates are symmetrically and fixedly arranged on the slide way, the a sliding block matched with the positioning fixing plates is arranged on the slide way between the positioning fixing plates and the corresponding side machine frame, a pre-locking handle is arranged on the sliding block, and the sliding block is detachably connected to the positioning fixing plate through a plurality of bolts; a fixing block is arranged at the lower end of the sliding block, a swing arm is hinged to the lower end of the fixing block, rotating shafts with rollers are arranged between the free end of the swing arm, and a plurality of shaft holes matched with the rotating shafts are formed in the free end of the swing arm. According to the roller position adjusting device in the packaging film production, the structural design is reasonable, rapid positioning and installation of the roller can be realized, and the installation efficiency is improved; and the position of the roller can be adjusted through an air cylinder, and the practicability is high.

Description

technical field [0001] The invention relates to the field of color printing machines, in particular to a roller position adjustment device in the production of packaging films. 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 and their positions are fixed. They are extremely inflexible and difficult to use. To meet production needs, it is necessary to design a roller that can be adjusted in position. Contents of the invention [0004] The object of the present invention is...
