Problems solved by technology

[0004] The current situation is that in order to achieve high coating accuracy, it is necessary to use a non-contact coating method in conjunction with the back roller; however, in some cases, if the back roller cannot be installed due to space constraints, the contact type can only be sacrificed for quality. coating

Embodiment Construction

[0021] The present invention will be described below in conjunction with specific cases.

[0022] See figure 2 , figure 2 Disclosed is the first embodiment of the contact coating lip structure of the present invention; a contact coating lip structure provided in this embodiment includes a contact coating lip main body 1, and the contact coating lip main body One side of 1 is a slurry flow surface 11, and a contact portion 12 is provided on the side of the contact coating lip body 1 away from the flow surface 11, and the contact portion 12 is set as the contact portion 12 After the bottom surface 121 of the slurry is in contact with the substrate 2, the lower bottom 111 of the slurry flow surface 11 hangs above the substrate 2, so that the slurry flows out in a free state when flowing out. In this embodiment, the contact portion 12 is a bump away from the lower bottom 111 and the contact coating lip main body 1; the bottom surface 121 of the bump is a plane. The main body ...

Abstract

The invention relates to a contact type coating lip structure and an extrusion coating head thereof. The contact type coating lip structure comprises a contact type coating lip main body, one side surface of the contact type coating lip main body is a slurry flowing surface, a contact part is arranged on the side, far away from the flowing surface, of the contact coating lip main body, and the contact part is arranged so that after the bottom surface of the contact part is in contact with a base material, the lower bottom of the slurry flowing surface is suspended above the base material, so that slurry flows out in a free state. According to the contact type coating lip structure and the extrusion coating head thereof, the advantage of non-contact type coating effect can be achieved by using a contact type coating mode.

Description

technical field [0001] The invention relates to an improvement of an extrusion coating head, in particular to a contact type coating lip structure and an extrusion coating head thereof. Background technique [0002] Existing wet material extrusion coating, such as the coating of lithium battery electrode materials, is divided into two categories: non-contact coating and contact coating. The so-called non-contact coating means that the coating head is suspended above the substrate. After the slurry is squeezed out from the slit of the coating head, it falls on the substrate by free fall. The advantage of high cloth precision (coating accuracy includes but not limited to thickness, uniformity, etc.), the disadvantage is that non-contact coating can only be coated with a back roller, and it cannot be coated without a back roller of. [0003] The so-called contact coating (such as figure 1 (shown) means that the lip of the coating lip 100 on one side of the extrusion coating ...
