Extrusion die head adjusting device

Abstract

The invention relates to an extrusion die head adjusting device. The device comprises an extrusion die head, an extrusion die head supporting seat, and a fixed bottom plate, wherein the extrusion die head is used for spraying coating materials to a basal body; the extrusion die head is mounted on the extrusion die head supporting seat, and the extrusion die head supporting seat is mounted on the fixed bottom plate; the device further comprises a micro-adjusting device, which is used for adjusting the position of the extrusion die head, and a guiding device; the guiding device is mounted between the extrusion die head supporting seat and the fixed bottom plate and is used for reducing a friction force during a lateral movement; and a fixed end of the micro-adjusting device is mounted on the extrusion die head supporting seat or the fixed bottom plate and is used for adjusting a lateral position of the extrusion die head and the extrusion die head supporting seat. Due to adoption of the extrusion die head adjusting device provided by the invention, a problem that unqualified products are caused due to lag of a lateral contraposition adjustment and repeated adjustment of a coating area relative to the basal body is solved through controlling the position of the extrusion die head. Through adopting the micro-adjusting device to directly adjust the lateral position of the extrusion die head, the lateral contraposition accuracy of the coating area can be intuitively and properly adjusted.

Description

technical field [0001] The invention relates to the field of coating machines, more specifically, to an extrusion die adjustment device. 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 Coating thickness is controlled 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. When the extrusion coater implements coating, the coating width value is determined according to the opening width of the gasket in the...
