Paint spraying auxiliary mechanism capable of keeping paint spraying distance and avoiding sagging for hardware

Abstract

The invention relates to the technical field of hardware processing, and provides a paint spraying auxiliary mechanism capable of keeping a paint spraying distance and avoiding sagging for hardware. The paint spraying auxiliary mechanism comprises a machine body, wherein a telescopic rod is movably connected to the interior of the machine body, a pressing plate is movably connected to the bottom of the telescopic rod, and a retractable rod is fixedly connected to the bottom of the pressing plate. According to the paint spraying auxiliary mechanism capable of keeping the paint spraying distance and avoiding the sagging for the hardware, a pressing block makes contact with a hardware iron workpiece, a compression spring is continuously compressed along with movement of the pressing plate, and when the compression spring is compressed to 5 cm, the elasticity of the compression spring enables a clamping plate to get rid of the limitation and move upwards; the compression spring is compressed to 5 cm so as to control a distance between a spray head and a surface to be sprayed to be within a set range and avoid the sagging, the clamping plate drives a curved bar to rotate, the curved bar extrudes paint through a piston, the piston extrudes the paint out of the interior of a paint box, and due to the fact that the clamping plate instantly gets rid of the limitation by the compression spring, the extrusion force of the clamping plate is large, and paint dripping caused by the too small spraying pressure is avoided.

Description

technical field [0001] The invention relates to the technical field of hardware processing, in particular to an auxiliary mechanism for spraying paint on hardware to keep paint spraying distance and avoid hanging. Background technique [0002] Hardware refers to five metals including gold, silver, copper, iron, and tin. Among them, iron is a metal commonly used in daily production. Since the workpiece made of iron is very easy to react with oxygen, the reaction produces oxides, and the oxidized iron workpiece not only reduces its precision. , the aesthetics also become lower, and the protection of iron workpieces by spraying paint can effectively prevent rust. Spraying paint directly cuts off the iron workpieces from contact with oxygen for protection. [0003] In the prior art, the distance between the nozzle and the spraying surface is too close and the spraying speed is slow, which will lead to the phenomenon of sagging on the surface of the iron workpiece, which not only...

Problems solved by technology

[0003] In the prior art, the distance between the nozzle and the spraying surface is too close and the spraying speed is slow, which will lead to the phenomenon of sagging on the surface of the iron workpiece, which not only reduces the precision of the iron workpiece, but also reduces its aesthetics, and the attached particles at the bottom are covered by the paint. Covering will cause local bulges, so a hardware spraying auxiliary mechanism that keeps the paint spraying distance to avoid sagging came into being
