Coating machine oven system

Abstract

The invention discloses a coating machine oven system comprising an infrared heating unit and a steam heating unit arranged in succession. The infrared heating unit comprises a plurality of infrared heating tubes. The steam heating unit comprises an intake passage, an air heating cavity, a base material heating cavity, an exhaust passage and a return air passage; a heating coil is disposed in the air heating cavity; an upper nozzle and a lower nozzle are disposed in the base material heating cavity; air enters the air heating cavity from the intake passage; the heating coil with steam heats up the air in the air heating cavity; the heated air is blown out of an air outlet of the upper nozzle and an air outlet of the lower nozzle; base material successively passes by one side of the infrared heating tubes between the upper nozzle and the lower nozzle; part of the air in the base material heating cavity is discharged from the exhaust passage, and the other part of the air returns from the return air passage to the intake passage. The coating machine oven system has the advantages that preheating is not required, heat conversion efficiency is high, energy consumption is low and temperature is even.

Description

technical field [0001] The present invention relates to a coater oven system. Background technique [0002] When producing electrodes, it is necessary to coat the electrode material on the substrate, and the coating of the electrode material on the substrate needs to be realized by a coating machine. The coating machine includes a slurry tank, a coating roller, a doctor roller and an oven. After the material is added to the slurry tank, the coating roller and the scraper roller work, the substrate is driven by the coating roller and coated with the slurry by the scraper roller, and then the substrate coated with the slurry is dried in an oven to obtain a finished product Electrode, at present, the oven on the coating machine generally uses electric heating, that is, the electric heating wire is used to heat the air, and then the heated air is blown to the surface of the substrate after the slurry is coated to dry the substrate. This type of electric heating oven has low hea...

[0002] When producing electrodes, it is necessary to coat the electrode material on the substrate, and the coating of the electrode material on the substrate needs to be realized by a coating machine. The coating machine includes a slurry tank, a coating roller, a doctor roller and an oven. After the material is added to the slurry tank, the coating roller and the scraper roller work, the substrate is driven by the coating roller and coated with the slurry by the scraper roller, and then the substrate coated with the slurry is dried in an oven to obtain a finished product Electrode, at present, the oven on the coating machine generally uses electric heating, that is, the electric heating wire is used to heat the air, and then the heated air is blown to the surface of the substrate after the slurry is coated to dry the substrate. This type of electric heating oven has low heating efficiency, high energy consumption, uneven heat in the oven, and the problem that part of the substrate is not dried and part is overheated, and the above oven needs to be preheated before use. The above oven can be used to dry the substrate after the air is heated to the set temperature
