As shown in the figure, a novel extrusion coating gasket is glued to point device, including the gasket 2 that is located between the last 11 and the lower 12 of shower nozzle 1, the one end of gasket 2 is opened has the opening of holding pole piece thick liquids spun, and open-ended both sides all are equipped with holds ceramic thick liquids spun ceramic runner 27, and the top of gasket 2 is opened downwards has the screw through-hole 21 of holding the feeding of ceramic thick liquids, still opens the guiding gutter 22, the gathering groove 28 that hold ceramic thick liquids and flow through in the gasket 2, screw through-hole 21, guiding gutter 22, gathering groove 28, ceramic runner 27 communicate in proper order.
The position of the screw through hole 21 corresponds to the position of the screw hole 111 of the upper member 11.
The feeding of the ceramic slurry is realized by using the screw hole 111 of the common nozzle 1, the coating of the ceramic slurry and the coating of the pole piece slurry are simultaneously carried out, the material loss is reduced, the cost of equipment and accessories is reduced, and the product quality and safety are improved.
The common nozzle 1 is used for realizing synchronous coating of the ceramic slurry on the edge and the slurry on the middle pole piece, and the single nozzle 1 is used for realizing double-coating function, so that the double-coating spraying function of the special dispensing nozzle 1 is achieved.
The position of the screw through hole 21 on the gasket 2 corresponds to the position of the fixed screw hole 111 of the upper piece 11 of the common spray head 1, the screw installed in the screw hole 111 is removed, then the ceramic slurry feeding tool is installed by means of the original screw hole 111, and the ceramic slurry is conveyed into the screw through hole 21 of the gasket 2. The ceramic slurry flows through the screw through hole 21, the guide groove 22 and the gathering groove 28 in sequence, and finally flows out of the ceramic flow passage 27.
The gathering groove 28 can gather and pressurize the ceramic slurry flowing from the diversion trench 22, so as to ensure the stable flow of the sprayed ceramic slurry.
The ceramic flow channel 27 can ensure that the two slurries can be covered together without leaking foil, and ensure that the width of the ceramic slurry coating meets the process requirements.
The gasket 2 includes diaphragm 24, and the both ends of diaphragm 24 all are fixed with the one end of riser 25, and the other end of riser 25 is fixed with the one end of bent plate 26, and two bent plates 26 set up relatively, the opening is located between two bent plates 26.

The outer edge 262 is inclined from the opening to the discharge end of the ceramic flow channel 27, so that the gasket 2 forms an outer chamfer which can reduce the edge spray flow of the pole piece slurry and prevent the edge from bulging due to the thick edge of the pole piece slurry after coating.
The gasket 2 has the functions of complete dispensing and covering, no foil leakage, extremely poor edge surface density and intermediate surface density, no bulge at the edge and the like by matching with the common nozzle 1. The equipment and accessory cost is reduced, the number of spare parts is reduced, and the performance and the safety of the battery are improved.
Each corner in the diversion trench 22 is of an arc-shaped structure.
Each corner is arc-shaped structure, so that each corner of the diversion trench 22 is an inner chamfer, and slurry is prevented from being accumulated at the corner to cause precipitation and accumulation.
The guide groove 22 is inclined from the cross plate 24 toward the opening direction near the side wall 221 of the opening.
Interior oblique ceramic guiding gutter 22 for guiding gutter 22 inclination and silo 122 keep safe distance, prevent to spout the material in-process two kinds of thick liquids and appear the compounding phenomenon.
The bottom of the lower part 12 is provided with a pole piece slurry feeding hole 121, the top of the lower part is provided with a trough 122 downwards, and the bottom of the trough 122 is communicated with the pole piece slurry feeding hole 121.

The common spray nozzle 1 which can not simultaneously coat two kinds of slurry and the matched novel gasket 2 are used for realizing the function of simultaneously coating two kinds of slurry, the practicability is stronger than that of the spray nozzle 1 which can simultaneously coat two kinds of slurry in a professional way, and one kind of spray nozzle can be freely switched with two kinds of coating modes, so that the equipment spare part cost is greatly reduced.
The specific using process is as follows:
when the device is used, the foil driven by the roller is arranged at the opening close to the gasket 2, so that the slurry sprayed by the spray head 1 can be opposite to the position of the foil to be coated.
The ceramic slurry feeding tool is installed by using the screw hole 111 of the upper piece 11 of the original spray head 1, and the ceramic slurry is conveyed into the screw through hole 21 of the gasket 2. The ceramic slurry flows through the screw through hole 21, the guide groove 22 and the gathering groove 28 in sequence, and is finally sprayed out from the ceramic flow passage 27 to coat the continuously rolling foil.
Meanwhile, pole piece slurry is fed from a pole piece slurry feed port 121 of a lower piece 12 of the spray head 1, and then the pole piece slurry is sprayed into a material groove 122 to be stably stored and then sprayed out to coat the continuously rolling foil.
Therefore, the simultaneous coating of the pole piece slurry and the ceramic slurry can be realized, the coating time is saved, the cost of accessories required by coating is reduced, and the simultaneous coating of the two slurries is completed by using the common spray head 1.
It is noted that, in the coating process, only one kind of slurry can be coated according to the requirement, and the applicability is strong.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
