Paint surface drying device for aluminum alloy door and window production

Abstract

The invention belongs to the technical field of aluminum alloy door and window production, and especially relates to a paint surface drying device for aluminum alloy door and window production. The following scheme is disclosed: the paint surface drying device for aluminum alloy door and window production comprises a workbench and a heating cover, wherein connecting holes are formed in the outer wall of the bottom of the heating cover at equal intervals, and the inner wall of each connecting hole is fixedly connected with a blast cover; and the outer wall, located at the inner side, of each blast cover is fixedly connected with a sealing ring, the inner wall of each sealing ring is fixedly connected with a blast pipe, each blast cover communicates with the corresponding blast pipe, and adaptive holes are formed in the outer wall, located at the inner side, of each blast cover at equal intervals. According to the invention, by arranging a retention assembly, after gas is guided into a heating cover through a gas pump, the gas flows through an electric heating pipe, the electric heating pipe heats the gas, and most of the heated gas passes through an arc-shaped reciprocating plate and reaches the electric heating pipe again under the action of a retention plate and a baffle at the two sides of the electric heating pipe; and therefore, the gas is heated in a reciprocating mode through the electric heating pipe, the temperature of the blown gas is increased, and the hot gas drying effect is improved.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy doors and windows production, in particular to a paint surface drying device for aluminum alloy doors and windows production. Background technique [0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles, and fan materials. They are called aluminum alloy doors and windows, referred to as aluminum doors and windows; Load rods) base material and wood, plastic composite doors and windows, referred to as aluminum-wood composite doors and windows, aluminum-plastic composite doors and windows; in the production process of aluminum alloy doors and windows, in order to improve their aesthetics, the surface needs to be painted, after painting , Accelerate the formation of the paint surface, and dry it through the drying device.

AI Technical Summary

Problems solved by technology

[0003] During the production process of existing aluminum alloy doors and windows, the paint surface of the doors and windows needs to be dried by a drying device. In order to improve the drying efficiency, the gas is generally blown out by a blower, and the gas is heated by an electric heating tube. The hot air dries the paint surface, and when the gas blown by the blower blows to the paint surface, there is a certain momentum, which will impact the paint on the paint surface of aluminum alloy doors and windows. The paint is in a relatively wet state, and it is easy to Ripples appear under the action of momentum, which leads to a decrease in the aesthetics of the dried paint surface and reduces the use value of the drying device
