An improved system for applying a coating to a sheet is disclosed. The system allows precise control of the actuation of the valves and movement of the nozzle to create a plurality of coating profiles. The system includes a controller, which is used to actuate the valves to begin and terminate the flow of material onto the sheet through a nozzle. In addition, the controller may move the nozzle from its operative position to an inoperative position away from the sheet. In some embodiments, a fluid displacement mechanism is used. The controller is also able to coat the opposite side of the sheet. Registration of the coating can be programmed to be in exact alignment, or advanced or delayed by a specific amount.

A flow adjusting mechanism of a die head of a coater and a working method thereof are provided. The flow adjusting mechanism includes a coarse adjustment mechanism, a fine adjustment mechanism, and a flow choking block which are sequentially arranged from top to bottom. The flow choking block is arranged above a coating slit. A central part of a top surface of the flow choking block is vertically provided with an adjustment rod. The fine adjustment mechanism is connected between the coarse adjustment mechanism and the adjustment rod.

Disclosed is a coating die and a battery electrode plate coating apparatus. The coating die is configured to apply a slurry on a substrate. The coating die includes a die body and a rectifying mechanism. The die body is provided with a discharging outlet. The rectifying mechanism is provided with a feeding inlet and a branching channel, where the feeding inlet is configured for injecting the slurry, the branching channel communicates with the feeding inlet and is provided with multiple branching openings, and the rectifying mechanism is exposed to the outside of the die body and is detachably connected to the die body, so that the multiple branching openings communicate with the discharging outlet.

An insulating liquid supplying device includes an insulating liquid tank for receiving insulating liquid, a slot die for discharging insulating liquid to the outside, and an insulating liquid header located at the upper part of the slot die for conveying insulating liquid transferred from the insulating liquid tank to the slot die. A pipe connecting the insulating liquid tank, slot die, and insulating liquid header permits transfer of the insulating liquid, and a transfer pump is provided in the pipe to transfer insulating liquid from the insulating liquid tank to the slot die.

A power storage device and an applicator is obtained that achieve an increase in capacity and an improvement in productivity, and that enable the thickness of a mixture layer to be inhibited from varying. A positive electrode mixture slurry is discharged into discharge regions of a belt-like positive electrode current collector that extend in a length direction of the positive electrode current collector from discharge nozzles corresponding to the respective discharge regions to form a positive electrode mixture layer on the positive electrode current collector. The discharge regions are arranged such that a part of each of the discharge regions overlaps a part of another of the discharge regions adjacent thereto when viewed in the length direction to form overlapping portions. The positive electrode mixture slurry is intermittently discharged to form an exposed portion on at least one of the discharge regions.

Disclosed is a coating machine. The coating machine includes: a movable component, a plurality of nozzles and a pump, the plurality of nozzles are sequentially arranged along the length direction of the movable component, the pump is configured for pumping coating agents into the nozzles, the movable component can drive the nozzles to move, and coating agents are coated on substrates by the nozzles with the movement of the nozzles.

A nozzle assembly may be used to apply fluid to an advancing substrate. The nozzle assembly includes a nozzle body made from a first material. The nozzle body may include one or more abrasion resistant materials fused to the nozzle body. The nozzle body may be configured to deposit a fluid, using a shim plate, onto the advancing substrate. As the substrate advances past the nozzle assembly, the substrate and/or the fluid may contact the nozzle assembly resulting in wear. The one or more abrasion resistant materials, which is different than the first material of the nozzle body, may be fused to a portion of the nozzle body to reduce the wear and prolong the life of the nozzle body. Thus, the portion of the nozzle body having the abrasion resistant material is restored rather than having to replace the entire nozzle body.
