Description

Technical Field

[0001] This utility model relates to the field of waste gas collection technology, specifically a waste gas collection device for gravure printing machines. Background Technology

[0002] A gravure printing machine is a machine that uses gravure printing plates for printing, mainly used for flexible packaging printing. The gravure printing process uses a large amount of ink and solvents, which will evaporate in large quantities during the printing and drying process, forming exhaust gas. Therefore, exhaust gas collection systems are installed in printing workshops to control the level of air pollution and protect the health of workers.

[0003] Existing patent application number: 202223385757.6 A printing exhaust gas collection hood includes an air intake hood, the top of which is connected to a connecting box, and the interior of the connecting box has a cavity. A side plate is movably installed on the outer surface of the limiting vertical plate, and the side plate is divided into two pieces, which are far apart from each other. Three ventilating plates are fixedly installed between the side plates, which are far apart from each other, thereby forming two cavities.

[0004] The aforementioned patent describes a printing exhaust gas collection hood. In practical use, the collection hood is usually connected to the exhaust gas pipe using a corrugated pipe. The corrugated pipe itself supports expansion and contraction, providing excellent adjustability for the collection hood to be placed in a suitable position. However, the collection hood lacks additional support structure besides the corrugated pipe. As the corrugated pipe is used for a long time, its material will gradually age and lose elasticity, resulting in a decrease in the support performance of the collection hood. During negative pressure suction, it is prone to shaking and instability, affecting actual use. Therefore, we propose a gravure printing machine exhaust gas collection device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a gravure printing machine exhaust gas collection device to solve the problems mentioned in the background art.
