PM-32FD film processing machine

Introduction

     The film processing machine is a specialized device designed to handle the development of photographic films used in various industries such as printing, medical imaging, and advertising. It ensures that the images on the film are clear, accurate, and suitable for high-quality output. The machine performs a series of chemical processes including developing, fixing, and drying, all in an efficient and controlled manner. Whether it's for plate-making in screen printing, X-ray image processing, or large-scale poster production, this equipment plays a crucial role in achieving the desired visual results.

     This advanced film processor features a multi-tank system with dedicated compartments for developer, fixer, and washing water. Each tank is equipped with a circulation mechanism to maintain consistent chemical concentration and temperature throughout the process. The conveying system uses motors, rollers, and gears to precisely control the movement of the film through each stage, ensuring optimal exposure time and uniform processing. The drying section offers two methods: hot air drying and heated drum drying, both of which efficiently remove residual chemicals and prepare the film for storage or further use.

Development principle:

     After exposure, the film enters the developer of the film processor, and the chemical components in the developer react chemically with the exposed photosensitive material on the film. The photosensitive material in this area is converted into a visible black or other color image material, and the image gradually appears. In the unexposed area, the photosensitive material reacts very slowly or almost not at all with the developer. The photosensitive material in these areas remains basically the same and will be removed or retained as a blank part in the subsequent processing process, thus forming a developed image corresponding to the exposure pattern. After development, the film enters the fixer, and the unreacted photosensitive material on the film fixes the image that has been formed. The chemical components in the fixer can react with the unreacted photosensitive material, dissolve it and wash it off the film, leaving only the stable image that has been developed. After the fixation process, the image on the film will no longer be affected by subsequent chemical treatments or external factors. After the fixation is completed, the film needs to be dried to remove the residual developer and fixer on the film. Water such as dry film is dried for subsequent use and storage.

Details-Basic structure

• Chemical tank part: It includes multiple chemical tanks, which respectively hold developer, fixer, washing water, etc. The chemical tank is usually equipped with a circulation system to ensure uniform concentration and temperature of the chemical solution.

• Conveying system: It is composed of motors, rollers, gears, etc., which can accurately control the conveying speed and position of the film in the medicine tank and drying area, ensure that the film stays in each processing area for a sufficient time, and ensure the washing and drying effect.

• Drying part: There are two common methods: hot air drying and heated drum drying. Hot air drying blows the heated air to the surface of the film through a fan; heated drum drying allows the film to pass through the heated drum surface and achieves drying through heat conduction.

• Control system: It can realize precise control of parameters such as washing temperature, time, conveying speed and drying temperature. Parameters can be entered manually, or multiple washing modes can be preset to meet the washing needs of different types of films.
