Abstract

The invention relates to the technical field of ovens, and particularly relates to a drying oven using air floating rollers. The drying oven comprises an oven body, wherein an inlet and an outlet areformed in the oven body. The drying oven further comprises a plurality of air floating rollers which are all parallel to the ground and arranged on the side wall of the oven body, and the plurality ofair floating rollers are arranged in a vertically-staggered mode; each air floating roller comprises an inner roller core and an air return device, wherein the inner roller core is of a hollow cylindrical structure, a plurality of protruding blocks are arranged on the periphery of the inner roller core in the axial direction of the inner roller core in a surrounding mode; the connecting line of the centers of the top walls of the plurality of protruding blocks forms the outer contour of the air floating roller; the bottoms of every two adjacent protruding blocks are connected through the inner roller core; air outlet holes are formed in the side walls, in the axial direction of the inner roller core, of the protruding blocks; air outlet cavities are formed in the protruding blocks and theinner roller core; the air outlet cavities communicate with the air outlet holes; and the air return device is arranged in the oven and transmits airflow in the oven to the outside of the oven. According to the drying oven using the air floating rollers, the occupied area of the oven can be reduced, and deformation of a diaphragm in the drying process can be accurately controlled and handled.

Description

technical field [0001] The invention relates to the technical field of ovens, in particular to a drying oven using air rollers. Background technique [0002] Coater is a very important production equipment widely used in electronics, photovoltaic, printing, textile and leather industries. Due to its unique structure and characteristics, lithium-ion batteries need to form a repeated overlapping unit of positive electrode / diaphragm / negative electrode / diaphragm, and the coating process is especially suitable for the production of each layer. Therefore, the coating machine is widely used in the manufacture of positive and negative electrodes and separator coatings of lithium batteries. Slurry making, coating, and drying are three basic steps in the coating process, which together determine the product quality. [0003] The existing drying process is realized by an oven. There are support rollers in the conventional oven to support the coated product and use the heat in the ov...
