Problems solved by technology

[0003] A utility model patent 02225377.7 with an application date of January 25, 2002 discloses an automatic film loading device for a laser photoplotter, which consists of a roller, a roller positioning device, an automatic film loading mechanism, an automatic film pressing device, and a grating phase locking device. , laser generation platform, screw rod, polished rod and motor, etc. This technology changes the manual loading method into machine automatic loading, making the loading convenient and fast. However, when working, the staff must manually position in the darkroom. Only one piece of film can be automatically loaded at a time, and batch processing is not possible, which makes the photoplotter low in efficiency and low in yield
Due to the need to manually operate in the darkroom during work, the staff have to work in the darkroom and the smelly environment for a long time, which is very harmful to the human body, and human factors have a great impact on the production of film

Abstract

Through posts and angle bar rack, the equipment is fixed above platform of laser light plotter. A small platform is fixed on upper parts of posts. The equipment includes air flow control part, can part, film shift control part, part for pressing film, drum control part for spinning in slow speed, and guide plate for loading and unloading film. Advantages of the invention are: darkroom is net needed for loading or unloading film; even, operator can operate plotter through network, eliminating influence on film from artifacts, raising yield and efficiency.

Description

technical field [0001] The invention belongs to the technical field of auxiliary equipment for laser photoplotters. Background technique [0002] Laser photoplotters are mainly used to draw various graphics, images and text or symbols on photosensitive film.
