Pneumatic film roll loading and unloading mechanism of printer

Abstract

The invention discloses a pneumatic film roll loading and unloading mechanism of a printer. The mechanism comprises a main swing arm and a lower swing arm, one end of the lower swing arm is connectedon the main swing arm through a swing bearing, an inner side of the main swing arm is provided with a small air cylinder, the main swing arm is fixedly connected with a sliding rail through a screw, the sliding rail is provided with a sliding block movably connected with the sliding rail, a push rod is jointly mounted at one end of a connection part between the sliding rail and the air cylinder through a bearing, a fisheye connector connected with the small air cylinder is mounted on the push rod, and one end of the push rod stretches to the outside of the main swing arm. The printer pneumaticloading and unloading film roll mechanism is wholly simple in structure and rational in design, respectively drives rotation and movement of the main swing arm through a big air cylinder and the small air cylinder to load and unload a relatively heavier film roll, reduces work intensity of workers, increases operation safety and reduces occupational injury of damage to lumbar vertebra caused by up and down loading and unloading of operators.

Description

technical field [0001] The invention belongs to the technical field of printing machines, and specifically refers to a pneumatic loading and unloading film roll mechanism of a printing machine. Background technique [0002] Sometimes it is necessary to cover the printed product during printing. Since the film is in a roll structure, the film roll needs to be placed on the printing machine when it is used. The existing printing machine is usually used when placing the film roll or removing the film roll. Manual operation is not only time-consuming and labor-intensive, but also because the film rolls are generally heavy, about 100 kilograms, after a long period of installation or disassembly, the lumbar spine of the operator will inevitably cause work-related injuries. Contents of the invention [0003] In order to solve the above problems, the present invention provides a pneumatic loading and unloading film roll mechanism for a printing machine, the specific scheme is as f...
