Description

TECHNICAL FIELD

[0002] Line marking supplementary coating drying machine is a kind of equipment used in the field of pop-up lid production, and its main function is drying. In the line marking supplementary coating process of pop-up lid, after using supplementary coating liquid to supplement coating, it needs to dry quickly to facilitate subsequent packaging and packaging. It accelerates the volatilization of moisture or solvent in the supplementary coating liquid by generating heat. For example, for water-based paint, the drying machine can control the temperature in a suitable range, which can accelerate the evaporation of moisture, and will not cause the supplementary coating liquid to crack or the pop-up lid to deform due to too high temperature.

[0003] When pop-up lid enters the oven, the coating has high moisture content, and the water needs to be evaporated quickly at high temperature. As the pop-up lid moves in the oven, the moisture gradually decreases, and the required temperature also gradually decreases. The U-shaped air duct is designed, and the temperature of the air outlet gradually decreases from the air inlet along the U-shaped air duct, which is the same as the flow direction of the pop-up lid, meets the requirements of coating curing on temperature, and improves the overall thermal efficiency of the oven.

[0004] However, the current drying air duct design is mostly straight, the drying path is short, the temperature difference between the front and back is not obvious, which is not conducive to the gradual drying of pop-up lid, and the space utilization is low. UTILITY MODEL CONTENTS
