Document Type and Number:
WIPO Patent Application WO/2019/137069
Kind Code:
A1
Abstract:
A spring surface flocking method, comprising the following steps: S1: feeding the material: using a hook (2) to secure a spring above a conveyor chain, the spring entering a production line with the conveyor chain; S2: electrostatic spraying: the spring enters an automatic production line with the conveyor chain; S3: electrostatic flocking: the spring enters an electrostatic flocking chamber for flocking after being sprayed with adhesive; S4: curing: the spring entering a drying apparatus for drying after flocking; S5: removing excess fluff: the spring passes through a brush and compressed air is used to blow the spring surface to remove excess fluff on the spring surface; and S6: discharging the material: extracting the spring after flocking and placing into packaging. The present method is suitable for round, oval, and cobble shaped steel wire springs, and is suitable for coating surfaces such as electrophoretic coating and zinc-aluminum coating. The present method uses electrostatic flocking, fluff being implanted into the adhesive by means of electrostatic adsorption, and the fluff having high fastness after curing.
