At the density fluctuation of coating, cause intermediate surface density high, surface density low situation in both sides influences the consistency of product.
Utility model content
In view of this, pressure when discharging can be kept to be evenly distributed it is necessary to provide a kind of improved gasket.
A kind of gasket, for being coated with extrusion head, the gasket includes gasket body, and it is convex that the gasket body is equipped with one
It rises, the gasket further includes two side plates positioned at the gasket body two sides, and each side plate includes being arranged in the pad
First plate of the corresponding side of piece main body and along the gasket body length direction extend the second plate, the height of the protrusion and
The height of first plate of the side plate is identical.
Further, the shape of the protrusion is arc-shaped or trapezoidal.
Further, the side plate upwardly extends.
Further, the gasket is equipped with film outlet port, and the film outlet port is oppositely arranged with the gasket body.
Further, the first plate of the side plate is at right angles arranged with the gasket body.
Further, the side plate is an integral structure with the gasket body.
Further, mounting hole is equipped on the gasket body and side plate.
A kind of coating extruder, including die head and gasket, the gasket are arranged on the die head.
Gasket provided by the utility model can effectively buffer intermediate discharge port by the convex design in gasket body
Pressure when discharging is consistent the pressure of all positions of die head when discharging, and face is close when coating just booting can be effectively prevented
The fluctuation of degree makes the quality of production more guaranteed, also reduces cost to improve the consistency of product.

Unless otherwise defined, all technical and scientific terms used herein are led with the technology for belonging to the utility model
The normally understood meaning of the technical staff in domain is identical.Terminology used in the description of the utility model herein only be
The purpose of description specific embodiment, it is not intended that in limitation the utility model.Term as used herein " and/or " include
Any and all combinations of one or more related listed items.
Referring to Fig. 1, Fig. 1 is the structural schematic diagram of the gasket 100 in an embodiment of the present invention, the gasket 100
For the coating extrusion process of lithium battery, the gasket 100 is mounted between the die head up and down of coating extrusion die, the gasket
100 are an integral structure, and the gasket 100 includes gasket body 10, the side plate 20 positioned at 10 two sides of gasket body.
In the present embodiment, the gasket 100 is equipped with film outlet port 101.It should be understood that the shape of the gasket with it is right
The coating extrusion die answered is adapted, the shape and structure being not limited in present embodiment.
The gasket body 10 is equipped with a protrusion 11, and described raised 11 are located at the side that the gasket body 10 upwardly extends
To.In the present embodiment, the protrusion is arc-shaped or trapezoidal, and in other embodiments, raised 11 shape is also
Can be it is knockdown, if top half be circular arc, lower half portion be it is trapezoidal.
The side plate 20 is arranged in the two sides of the gasket body 10 and upwardly extends, in the present embodiment, the side
Plate 20 includes the first plate 21, and first plate 21 and the at right angles setting of gasket body 10, the side plate 20 further includes along institute
The second plate 22 that the length direction of gasket body 10 extends is stated, and two second plates 22 extend towards, second plate 22
At right angles it is arranged with first plate, the inside of the side plate 20 and the gasket body 10 forms a groove 201, described
