Problems solved by technology

In principle, it is no different from single-sided coating. Two sets of coating devices and two independent drying boxes are still needed. When drying, the idler rollers in the drying box support the pulp after the first drying. If the first drying is not complete, it will adhere to the idler rollers, resulting in damage to the idler rollers.
Moreover, this method requires the control system of the coating equipment to be more complicated and the maintenance cost of the equipment to increase

Abstract

The invention relates to a drying device specially for coating and specifically for transmitting and drying a coated base material. The drying device comprises a box body and press roller assemblies, wherein the press roller assemblies are arranged in the box body and correspondingly arranged at both sides inside the box body; each press roller assembly comprises an upper press roller and a lower press roller which are correspondingly arranged top and bottom, the upper press roller and the lower press roller are driven by a power device to rotate, and a gap used for clamping the blank part of the side edge of the base material is arranged between the upper press roller and the lower press roller. In the invention, the blank with certain width of the edge of the base material is clamped through roller clamping type transmission, and therefore, liquid size is prevented from being influenced in thickness uniformity by flowing because a foil is bent and shifted; a single-layer drying box can not only realize that double surfaces of the base material are both dried and save the energy consumption more than 50 percent, but also save the replacement time of materials; and in addition, the drying device is compact in structure and is increased the operation efficiency.

Description

technical field [0001] The invention relates to the field of coating machinery, in particular to a coating device for lithium battery manufacturing equipment, in particular to a special drying device for coating. Background technique [0002] Coating is an indispensable process in the production process of lithium-ion batteries, and it is also a key process that directly affects various performances such as battery safety, capacity, and consistency. Coating is to apply the prepared paste-like viscous slurry evenly, continuously or intermittently on the front and back sides of the substrate (aluminum foil or copper foil), to ensure the thickness consistency of each coating position, and Control the coating thickness within the tolerance range required by the process. [0003] The extrusion coating technology at home and abroad is becoming more and more mature, and the coating precision is getting higher and higher. The current extrusion coating method can only coat one side...
