Infrared lamp tube heated baking oven and coater

Abstract

The invention discloses an infrared lamp tube heated baking oven. The baking oven comprises a baking oven main body, an air return system and a heating system, wherein the heating system comprises a plurality of infrared lamp tubes arranged on the inner wall of the baking oven main body; the air return system comprises an air duct of which the two ends are respectively communicated with the baking oven main body, and during heating of the infrared lamp tubes, the air return system drives air in the baking oven main body to flow circularly along the air duct. The invention further provides a coater equipped with the baking oven. The same baking oven main body can save 60% of energy, the preheating time and the heating time are both short, and the preset temperature can be reached within a short period of time, so that the drying efficiency is high; the baking oven can work quickly, or the pitch number of the baking oven can be reduced to improve the efficiency and save the cost; the infrared lamp tubes enable the inner layer of the base body coating to be dry at first, and hot air driven by the air return system enables the outer layer of the base body coating to be dry at first, so that the inner layer and the outer layer can be uniformly dry but not crack, and accordingly, the yield is improved; the coater also has the above effects.

Description

technical field [0001] The invention relates to the field of coating machines, in particular to an oven heated by an infrared lamp tube and a coating machine. Background technique [0002] Ovens in the field of coating machines used to use air blowers to heat the air to dry the substrate. Due to the continuous heating of the circulating air, the energy consumption is large, the heating time is long, the drying time is also long, and the efficiency is low. At the same time, due to the long distance from the tuyere to the substrate, the wind is uneven in the middle and on both sides of the substrate, causing the covering on the substrate to crack easily during the drying process. [0003] Therefore, it is necessary to provide an oven and a coating machine with fast heating, low energy consumption and uniform drying process. Contents of the invention [0004] The present invention mainly provides an oven with energy saving and fast heating, and the secondary purpose is to pr...
