Intermittent waste gas recovering device for paint spraying of hardware machinery parts

Abstract

The invention relates to the technical field of hardware machinery, and discloses an intermittent waste gas recovering device for paint spraying of hardware machinery parts. The waste gas recovering device comprises a screw; the left and right ends of the screw are in meshing connection with moving blocks; moving rods are fixedly mounted at the lower ends of the moving blocks; guiding rods are movably mounted on the opposite surfaces of the moving rods; sliding rods are fixedly mounted on the opposite surfaces of the guiding rods; and a paint storage pipe is movably mounted at the lower ends of the moving rods. According to the intermittent waste gas recovering device for paint spraying of the hardware machinery parts, a fixing plate is driven to move downwards through opposite movement ofthe moving rods and cooperates with a fixing rod to be fixedly mounted on the screw, the position of the paint storage pipe is unchanged, the fixing plate moves downwards, a moving frame can have theexpanding phenomenon, then the size of an inner air suction bag is increased, the air sucking state appears, and harmful and toxic gas produced during paint spraying can be absorbed and treated.

Description

technical field [0001] The invention relates to the technical field of hardware machinery, in particular to an intermittent-based exhaust gas recovery device for painting hardware machinery parts. Background technique [0002] Hardware Traditional hardware products, also known as hardware, usually refer to five metals: gold, silver, copper, iron, and tin. After manual processing, they can be made into works of art or metal devices such as knives and swords. The scope of modern hardware More widely, such as hardware tools, hardware parts, daily hardware, etc., play a very important role in people's lives. [0003] Hardware and machinery parts are often painted when they leave the factory. On the one hand, the original color of the metal is covered to make the surface beautiful, and the surface can prevent rust. However, the current hardware machinery is in the process of painting. It will produce a lot of odor. If the staff often inhale this gas, it will be harmful to the bo...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a waste gas recovery device based on intermittent paint spraying for hardware and mechanical parts, which has the advantages of adsorbing harmful gases and uniform paint spraying, and solves the problem of a large amount of toxic gas emissions in the use of the existing devices Into the atmosphere, it will cause harm to the human body, and it is impossible to guarantee the uniformity of the spray paint
