Abstract
Description
Technical Field
[0001] The utility model relates to the field of coating machine equipment, and more specifically, to a battery coating machine gasket. Background Art
[0002] Lithium-ion batteries have the advantages of high voltage, high energy density, high safety, and low self-discharge rate. In the production process of lithium-ion batteries, the pole pieces need to be coated, which requires the use of a coating machine. Coating machines are mainly used for surface coating processes for films, paper, etc. This machine coats the rolled substrate with a layer of glue, coating or ink with specific functions, and then dries and rewinds it. It uses a special multifunctional coating head, which can achieve various forms of surface coating.
[0003] The coating gasket is an indispensable part of the coating machine. When coating different types of battery pole pieces, gaskets with different widths of discharge ports are required. The use and manufacturing costs are high, which is not conducive to improving production efficiency. Figure 7 Shown is a schematic diagram of an existing gasket structure.
[0004] The coating of soft-pack power lithium-ion batteries in the prior art is to fix the gasket between the upper and lower die heads, and the coating slurry enters the die head through the feeding pump. The slurry is sprayed out from the gasket and evenly coated on the positive and negative electrode foils. The die size is fixed, and the coating width is adjusted by the gasket. However, most of the gaskets in the prior art can only correspond to one coating width. Because the coating widths required for each are different during the research and development process, each time the coating width is changed, it is necessary to remake the gasket of the corresponding width, which leads to high costs and long production and purchase cycles, reducing the efficiency of coating production.

[0007] The length of the front end of the gasket (end A-1) is slightly less than the width of the die lip (end A-2) by 5-15mm to prevent the protruding die from hitting the roller during installation. The rest of the length is consistent with the width of the die.
[0008] The main sheet 1 is the main body of the gasket, and the material is a smooth and pressure-resistant material. On the one hand, it prevents deformation during extrusion of the die head, and on the other hand, it prevents the material liquid from adhering during discharge.
[0009] The gasket fixing pin hole 2 is connected with the die head fixing pin hole through a fixing pin to play a fixing role. The shape is an irregular circular hole to facilitate the slight sliding of the pin when passing through the fixing.
[0010] The gasket positioning hole 3 is connected to the die head positioning hole through a positioning pin to play a positioning role. The shape is generally a round hole.
[0011] The insertion groove 4 has a smooth surface to reduce insertion friction and is transitionally matched with the T-shaped piece 6.
[0012] The replaceable insert 5 is transitionally matched with the T-shaped piece 6 and can be replaced with different sizes according to the coating process. There is a scale 51 on it, and the size can be selected according to the scale. A groove is set in the middle of the replaceable insert, and the thickness of the replaceable insert is consistent with that of the main piece 1.

[0014] Bevel 7, requires smoothness, setting the bevel to reduce the adhesion of the liquid. Preferably, a rounded corner can be set.
[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] 1. The adjustable spacer with scale can be adjusted precisely, solving the problem of insufficient adjustment accuracy.
[0017] 2. The material of the utility model is smooth, and an oblique angle is set to reduce the residual liquid, thus avoiding the problem of material jamming during the adjustment process. BRIEF DESCRIPTION OF THE DRAWINGS
