A powder spraying process and equipment for heat preservation cover

Abstract

The invention provides a powder spraying process and equipment for a thermal insulation cover, belonging to the technical field of processing. The powder spraying equipment of this thermal insulation cover includes a cleaning machine, a powder spraying device and a curing device. The cleaning machine includes a body and a frame. The body is installed on the frame. The conveying mechanism, the powder spraying device includes a chassis, which is equipped with an upper conveying structure and a lower conveying structure, and the heat preservation cover passes through the upper conveying structure and the lower conveying structure in turn. There is at least one set of relative powder spraying mechanism 2, and the powder recovery device is connected to the chassis. The upper conveying structure is installed on the top of the chassis through the upper bracket, and the lower conveying structure is installed on the bottom of the chassis through the lower bracket. The curing device includes a curing box. , The curing box has a preheating chamber, a curing chamber and a cooling chamber. The invention enables the heat preservation cover to be sprayed with powder without dead angle in a clean state, and in addition, it is not easy to drop powder during curing.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a powder spraying process of a heat preservation cover and equipment thereof. Background technique [0002] Pressure cooker is also called pressure cooker, pressure cooker, is a kind of kitchen utensils. The pressure cooker uses the physical phenomenon that the boiling point of the liquid will increase at a higher pressure, and puts pressure on the water so that the water can reach a higher temperature without boiling, so as to speed up the efficiency of stewing food. It can be used to heat the cooked food to above 100°C. In high altitude areas, the pressure cooker can avoid the problem that the boiling point of water is lowered and the food is not easy to cook. [0003] The heat preservation cover is an important part of the pressure cooker. There is a powder spraying process in the production process of the heat preservation cover. After the powder spraying, the heat preservat...

AI Technical Summary

Problems solved by technology

[0006] In the existing powder spraying and curing process, the process of cleaning the heat preservation cover is generally lacking, which is easy to affect the powder spraying and curing quality of the heat preservation cover due to the adhesion of impurities, and the heat preservation cover is prone to powder drop and air bubbles. In addition, the application of the above two utility models can It can be seen that 1. When the heat preservation cover is spraying powder, it is easy to cause incomplete powder spraying due to the shelter of the hanger. 2. The air duct directly sends the wind into the curing drying tunnel. Because the powder that needs to be solidified is hit by the airflow generated by the wind, it will Make the powder flow, easy to affect the curing quality
