[0002] In the extrusion coating of lithium battery pole pieces, the slurry properties are becoming more and more diverse, and the slurry temperature is also getting higher and higher (the temperature change of the slurry during the working process is required to be smaller and smaller). Before coating the die lip, it must be guaranteed to be within a stable temperature range. Most of the existing die heads include an upper die head, a lower die head, a gasket, a T-bar and a moving mechanism. The upper die head is hinged on the lower die head, a cavity is provided on the lower die head, and a feed port connected to the cavity is provided on the back side of the lower die head. The gasket is placed between the upper die head and the lower die head. The front end of the upper die head and the lower die head forms a discharge lip, and a channel connecting the discharge lip and the cavity is formed between the upper die head and the lower die head. The T-bar is vertically slidably arranged on the upper die head, and its bottom end is placed in the channel. The moving mechanism is installed on the upper die head, and its moving end is connected to the T-bar and drives the T-bar to move up and down on the upper die head. Although this die head can meet the use needs to a certain extent, its disadvantage is that it cannot keep the slurry at a high temperature at the die lip, and it is difficult to meet the coating requirements.
