The invention relates to an iron
pipe paint-spraying device, in particular to an efficient iron
pipe paint-spraying device for hardware. By the adoption of the efficient iron
pipe paint-spraying device for hardware, the technical purposes of good paint spraying effect, high paint spraying efficiency and simple operation are achieved. For achieving the technical purposes, the efficient iron pipe paint-spraying device for hardware comprises a base plate, a left side plate, a
pulley, a first sliding rail, a 7-shaped support, a first motor, a storage plate, a gear, a disc, a first connecting rod, a second connecting rod, a second connecting rod, a supporting rod, an air cylinder, a paint spraying head, a second sliding rail, a compression cylinder, a
piston, a first hose, a first one-way valve, a
brush, a first sliding block, a first spring and the like. The left side plate, the
pulley, the first sliding rail and the 7-shaped support are arranged at the top of the base plate in sequence from left to right. According to the efficient iron pipe paint-spraying device for hardware, a transverse plate and a third spring are utilized, so that the bush and an iron pipe are kept being in contact all the time, and the good paint spraying effect and high paint spraying efficiency are achieved.
