Description

Technical Field

[0001] The utility model relates to the technical field of UV printing, in particular to a centralized waste gas treatment device for UV printing. Background Art

[0002] UV printing is a printing process that uses ultraviolet light to dry and cure ink. It requires ink containing photosensitizers to be used in conjunction with UV curing lamps. Currently, UV inks have covered offset printing, screen printing, inkjet, pad printing and other fields. The traditional printing industry generally refers to UV as a printing effect process, which is to apply a layer of varnish on the printed pattern, mainly to increase the brightness and artistic effect of the product and protect the surface of the product. It has high hardness, corrosion resistance, friction resistance, and is not prone to scratches.

[0003] For example, the Chinese patent publication number is CN215427817U, and the technical solution disclosed in the patent document is as follows: a centralized waste gas treatment device for UV printing. In the utility model, a long strip hole is provided on the outer surface of the box body, and a glass fiber board, a metal wire mesh board and a carbon fiber board are slidably connected inside the long strip hole. One end of the glass fiber board, the metal wire mesh board and the carbon fiber board is fixedly connected to an extended handle and activated carbon, and the device can be taken out from the long strip hole on the surface of the box body, so that it is more convenient for the staff to clean the filter device, and the work efficiency of the staff is improved. A bottom plate is fixedly connected to the bottom of the box body, and a drawer is slidably connected to the top of the bottom plate surface. The inside of the drawer is movably connected to a filter net. When the device is working, larger dust in the waste gas will fall above the filter net, and smaller dust will fall below the filter net for classification and treatment. After the work is completed, the drawer is pulled out of the box body for cleaning, which makes it more convenient for the staff to clean.

[0004] The above technology collects dust generated during filtration through a drawer, but the dust automatically falls into the drawer, and the collection efficiency is low. Part of the dust will stick to the metal mesh plate, increasing the difficulty of cleaning the metal mesh plate. Utility Model Content
