Low-water-distribution developing plate processor

Abstract

The invention discloses a low-water-distribution developing plate processor, relates to a silk-screen equipment technology, and aims to solve the problems that the amount of waste water is large, the proportion of a developing solution contained in the waste water is very low, the purification difficulty is relatively high when people carry out recovery treatment, a certain degree of waste is caused, and the cost is low. According to the technical scheme, the device is characterized by comprising a base, two racks fixedly connected to the upper portion of the base and a workbench fixedly connected between the two racks, a conveying mechanism is arranged on the workbench, lifters are arranged in the racks, and a cover body is jointly and fixedly connected between the movable ends of the lifters on the two sides. According to the invention, a small amount of clear water can be used for cleaning the PS plate in which the developing solution is retained for many times, and wastewater with relatively high concentration can be fully recovered, so that resources can be protected and saved, and water resources can be prevented from being polluted.

Description

technical field [0001] The present invention relates to the technology of screen printing equipment, more particularly, it relates to a low-water distribution developing plate processor. Background technique [0002] PS version, commonly known as pre-coated photosensitive version, the pre-coated photosensitive version is a non-silver photosensitive material coated with a thin aluminum plate as a support and coated with a diazo photosensitive resin. [0003] In the current process of screen printing, either by scraping a layer of photosensitive adhesive on the screen to match the black lines printed on the transparent film for exposure, or by pre-coating a photosensitive plate for exposure, after the screen is exposed, It only needs to rinse the soft photosensitive adhesive on its surface, so that the screen can display the lines printed by people. This process has low efficiency and it cannot adapt to some special patterns. In the face of some special patterns and needs, peo...

AI Technical Summary

Problems solved by technology

[0003] When people are currently performing silk screen printing, they either scrape a layer of photosensitive adhesive on the screen to match the black lines printed on the transparent film for exposure, or use a pre-coated photosensitive plate for exposure. After the screen is exposed, It only needs to wash the soft photosensitive glue on the surface, so that the screen can show the texture printed by people. The process has low efficiency and it cannot adapt to some special patterns. Faced with some special patterns and needs, people have to The PS plate is used for exposure, and after exposure, it needs to be developed with a developer, and the developer needs to be cleaned after development, so as not to affect the subsequent screen printing process

[0004] However, the current plate processor, that is, the developing machine, is usually a series of steps of developing, cleaning and drying after people put the PS plate on the workbench and send it into the machine through its transmission mechanism. , in this process, especially for cleaning, the machine will spend a lot of water to clean the developer remaining on the PS plate, and there is no guarantee that it will be completely cleaned, and the large amount of wastewater generated by cleaning cannot be properly treated. At present, there are some technologies for recycling waste water. However, due to the huge amount of waste water and the low proportion of developer contained in it, it will be more difficult to purify when people carry out recycling treatment, and it will also cause a certain amount of waste
