Description

Technical Field

[0001] This utility model belongs to the field of battery production technology, specifically relating to an easy-to-clean coating die head. Background Technology

[0002] Currently, in battery production, the coating process involves uniformly applying slurry to the current collector. The continuous and stable surface density of the slurry on the electrode directly affects the battery's electrical performance. However, due to the sedimentation characteristics of the slurry used in the coating process, slurry residue accumulates inside the die cavity after prolonged coating. Furthermore, because of the inconsistent slurry flow velocity distribution within the cavity, when using a slurry with a narrow sedimentation window, the slurry easily accumulates rapidly in areas with slower flow velocity, forming slurry residue.

[0003] As the slurry flows through the cavity, the accumulated slurry migrates to the gap between the die lips. Due to the inconsistency in the particle size of the slurry, larger particles will get stuck in the gap and cannot be discharged, causing particle scratches. Smaller particles will be coated onto the current collector with the slurry, causing electrode particles. These particles will fall off after rolling, resulting in foil exposure defects.

[0004] Besides the defective particle scratches on the electrode itself, slight slurry accumulation requires stopping the machine for spraying. The slurry in the die lip gap is forcibly discharged by pressure. Severe slurry accumulation will cause high and uneven pressure in the cavity, which directly affects the quality of coated electrode. At this time, it is necessary to stop the machine, disassemble the die head for cleaning, and when reinstalling the die head after cleaning, it is necessary to test the die head gap, angle, shim installation position, and slurry circulation in the die head again, which seriously affects production efficiency.

[0005] In either case, it will result in the loss of slurry and a waste of labor. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide an easy-to-clean coating die head, thus solving the problems mentioned in the background art.

[0007] The purpose of this invention is achieved as follows: an easy-to-clean coating die head, comprising a die head body, a die head sealing ring and a side baffle on the left side of the die head body, a semi-circular cleaning nozzle on the left side of the die head body, and a side baffle sealing ring on the right side of the die head body. This invention reduces the frequency of die head disassembly due to material buildup, improves production efficiency, and saves production costs. Simple cleaning can be performed without disassembly; the semi-circular cleaning nozzle avoids the coating gasket, preventing wasted production capacity due to subsequent equipment adjustments caused by die head disassembly.

[0008] Further, the lower end of the die body is fixedly provided with a base plate, the side port baffle comprises a left baffle and a right baffle, the left baffle is fixedly connected to the left end of the base plate in vertical extension, and the right baffle is fixedly connected to the right end of the base plate in vertical extension.
