Problems solved by technology

When the die head is in the coating state, the lower die 3' is in a horizontal state, and the upper die 1' is in an inclined state. When installing the coating die head with this structure, it is easy to cause the emptying port of the upper die to not accurately correspond to the upper die cavity at the highest point, resulting in inefficient evacuation, making it difficult to use in batch coating processes

Abstract

The invention relates to the technical field of coating machine accessories, in particular to a double-layer coating die head and a coating machine. The double-layer coating die head comprises a lower die, a middle die and an upper die which are sequentially arranged from bottom to top. A first fluid distribution cavity is formed in the lower die. A second fluid distribution cavity is formed in the middle die. The first fluid distribution cavity is obliquely arranged. The second fluid distribution cavity is horizontally arranged. A first emptying opening communicating with the first fluid distribution cavity is formed in the middle die. A second emptying opening communicating with the second fluid distribution cavity is formed in the upper die. When the coating die head is installed through the structure, due to the fact that the second fluid distribution cavity is horizontally arranged, the second emptying opening can still be located at the highest point of the second fluid distribution cavity, emptying of the first fluid distribution cavity and the second fluid distribution cavity is facilitated, and intermittent coating is well achieved.

Description

technical field [0001] The invention relates to the technical field of coating machine accessories, in particular to a double-layer coating die head and a coating machine. Background technique [0002] There are many occasions in industrial production that require coating of double-layer coatings. For example, in the battery production industry, in order to enhance the safety performance of the battery, functional coatings are generally provided on the surface or bottom of the active material layer of the current collector. [0003] refer to figure 1 , there is a double-layer coating die head in the prior art, which consists of an upper mold 1', a middle mold 2', a lower mold 3', an upper gasket and a lower gasket, and the upper mold cavity is set on the upper mold 1' , the lower mold cavity is set on the lower mold 3'. When the die head is in the coating state, the lower die 3' is in a horizontal state, and the upper die 1' is in an inclined state. When installing the coa...
