Detailed Description

The present invention will be further explained with reference to the following detailed description and accompanying drawings:

example 1

Referring to fig. 1 and 2, an adjustable coating die shim is shown comprising: the gasket comprises a gasket body 1, a splitter plate 2 and four baffle plates 3.

The gasket main body 1 comprises a bottom edge 11 and two side edges 12 connected to two ends of the bottom edge 11, the bottom edge 11 and the side edges 12 are integrated, and the upper ends of the two side edges 12 both extend inwards to form a flow blocking part 13.

The bottom edge 11 and the side edge 12 are respectively provided with a fixing hole 14 at intervals, and the fixing holes 14 are used for being matched with screws to be fixedly connected with a die head of the coating machine.

Five notches I15 are arranged on the inner side of the bottom edge, notches II 16 are arranged at the end parts of the two flow blocking parts 13, and the two notches II 16 are opposite.

The lower end of the flow distribution plate 2 is provided with a first bump 21 matched with the first notch 15, and the first bump 21 is connected with the first notch 15; the die pad is a sheet with the thickness of about 1mm, and the assembly can be completed by aligning the first bump 21 with the first notch 15 and pressing and embedding the first bump into the second notch.

And both sides of the upper end of the flow distribution plate 2 are provided with a third notch 22, and the third notch 22 and the second notch 16 have the same size.

One end of the flow baffle 3 is provided with a second bump 31 matched with the second notch 16, and each flow baffle 3 is respectively connected with the second notch 16 or the third notch 22 through the second bump 31 in the same way as the first bump 21 and the first notch 15.

In the present embodiment, the other end of the baffle plate 3 is provided with a chamfer 32, and the chamfer 32 is provided because: when the extrusion type coating machine is used for coating, the flow velocity of slurry can be extremely high when the slurry flows through the edge of the flow baffle plate 3 and the edge of the flow distribution plate 2, the edge of a material area is easy to form a bulging edge after the slurry is dried in an oven, the rolling and the belt breaking are easy to cause, and the consistency and the safety of the battery capacity are seriously influenced.

The chamfer 32 is arranged on the flow baffle plate 3, so that the flow rate of slurry at the edge of the flow baffle plate 3 can be reduced, the flow rate of the slurry is uniform, the edge bulging phenomenon of a coating material area can be obviously reduced, and the problems of consistency and safety of battery capacity caused by the edge bulging phenomenon are further solved.

As a preferred embodiment, the first notch 15, the second notch 16, and the third notch 22 of this embodiment are all gradual notches with inner openings larger than outer openings, and may be trapezoidal structures, but are not limited to trapezoidal; the design of this type of notch may facilitate the fixation between the corresponding notch and the projection.

In order to facilitate the differentiation of the flow baffle 3 by an installer, the shape of each notch can be designed to be asymmetric (such as non-isosceles trapezoid), meanwhile, the three notches 22 on the two sides of the flow baffle 2 are not symmetric along the central line of the flow baffle 2 (as shown in fig. 3), and the two notches 16 on the two ends of the gasket main body 1 are also not symmetric along the central line of the gasket main body 1, so that the conditions that the flow baffle 3 is arranged on the front side and the back side and the left side and the right side are reversed are prevented.

In this embodiment, as shown in fig. 2, the coating types are two-out-of-one, and when the coating types need to be switched, the number of the splitter plates 2 only needs to be increased, and as shown in fig. 4, the coating types can be changed into three-out-of-one; when the coating width needs to be adjusted, the coating width can be changed only by replacing the current baffle plate 3 with other baffle plates with different lengths, so that the coating width has strong universality, and the coating device is beneficial to improving the production efficiency and saving the cost.

The above-mentioned embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
