Anti-corrosion spraying device for automobile sealing strip

Abstract

The invention discloses an anti-corrosion spraying device for an automobile sealing strip, and belongs to the technical field of automobile sealing part machining. The sealing strip guided by a rotating guide roller to move penetrates through flexible fiber smoothing faces of a pair of coating smoothing mechanisms after being sprayed with upper coating and lower coating, and the coating smoothingmechanisms are used for smearing the upper end face and the lower end face of the sealing strip; on the premise that double-sided coating spraying is achieved, the coating uniformity is improved, sagging caused by the fact that a certain position of a coating layer is excessively thick is effectively avoided, the inner end of a semiconductor chilling plate is used for refrigerating, the outer endof the semiconductor chilling plate is used for heating, and hot air flow is guided into a pair of drying mechanisms; the drying mechanism located on the left side of the upper fixing roller is used for increasing the coating temperature, the drying mechanism located on the right side of the upper fixing roller is used for baking the coating, a certain distance is reserved between the drying mechanism and the corresponding coating smoothing mechanism, a certain leveling time can be kept, sagging of the coating face due to excessively low air flow speed is avoided, and cold air flow is guided into the baked sealing strip through a heat dissipation mechanism to achieve 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
