Anti-corrosion spraying device for automobile sealing strip

Abstract

The invention discloses an anti-corrosion spraying device for automobile sealing strips, which belongs to the technical field of automobile sealing parts processing. After being sprayed with upper and lower paints, the sealing strips which are guided by rotating guide rollers pass through the flexible fiber smoothing of a pair of paint smoothing mechanisms. On the flat surface, the paint smoothing mechanism is used to smear the upper and lower end surfaces of the sealing strip. Under the premise of realizing double-sided paint spraying and improving the uniformity of the coating, it can effectively prevent the smearing layer from being too thick and cause sagging, and The inner end of the semiconductor refrigeration sheet is used for cooling and the outer end for heating, and the hot air flow is introduced to a pair of drying mechanisms. The drying mechanism located on the left side of the upper fixed roller is used to increase the coating temperature, and the drying mechanism located on the right side of the upper fixed roller The mechanism is used to bake the paint, and it has a certain distance from the paint smoothing mechanism, which can maintain a certain leveling time, and the air flow rate will not be too slow to cause the coating surface to hang, and the cold air flow is introduced through the heat dissipation mechanism To the sealing strip after baking to realize cooling and heat dissipation.

Description

technical field [0001] The invention relates to the technical field of automobile sealing parts processing, and more specifically relates to an anti-corrosion spraying device for automobile sealing strips. Background technique [0002] Automotive sealing strips are one of the automotive seals. Automotive sealing strips are mainly used in the gaps between body parts. The sealing strips include glass grooves, door frame sealing strips, rear door frame sealing strips, and some auxiliary parts of the engine room or door system. article etc. Taking the structure of the automobile door frame sealing strip as an example, its main body is composed of sponge foam tube, compact rubber and core material. The sponge tube part needs to be sprayed with silicone or polyurethane coating during production to improve the noise reduction of the sealing strip , wear resistance, sealing and frost resistance, and can prevent pollution of sheet metal and beautify the appearance, etc. [0003] Au...

Problems solved by technology

[0004] In the prior art, the spraying device generally uses the sealing strip to be placed on the conveyor belt, and a spray head is set above the conveyor belt to spray the lower sealing strip, but this spraying method can only spray one side of the sealing strip at a time, and then the sealing strip needs to be turned over Spraying again will cause the cumbersomeness of the whole spraying process; in addition, during the spraying process, when the coating temperature is too low, the humidity is too high, and the air flow rate is too slow, the paint solvent will volatilize slowly and cannot flow in a short time. Flat, causing the sprayed surface to sag, which will affect the spraying effect
