AI Technical Summary
In the new energy industry, during the coating process of viscous slurries, the increased depth of the grooves in the mesh structure leads to a decrease in the coating yield.
Interleaved grooves are set at the bottom of the mesh pit. The width of the grooves ranges from 2 micrometers to 6 micrometers, and the depth ranges from 1 micrometer to 6 micrometers. This structure reduces the adhesion between the slurry and the bottom of the mesh pit and improves the slurry transfer efficiency.
The staggered groove structure improves the transfer effect of viscous slurry and increases the coating yield.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of precision coating technology, and in particular to a viscous slurry coating anilox roller. Background Technology
[0002] In the new energy industry, the coating of viscous slurries often adopts a mesh structure. The mesh structure is a large-opening grid with smooth-bottomed pits inside the grid to facilitate the containment of slurry. Due to the viscosity of the viscous slurry itself, it is not conducive to the transfer of slurry during high-speed coating. In order to increase the coating thickness, the depth of the pits needs to be deeper and deeper. However, with a fixed opening, the deeper the pits, the more unfavorable it is for the transfer of slurry, thus reducing the coating yield. Utility Model Content
[0003] The purpose of this invention is to provide an anilox roller for coating viscous slurries, which solves the technical problem of low coating yield in existing technologies. The various technical effects of the preferred solutions among the many technical solutions provided by this invention are detailed below.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] The present invention provides a viscous slurry coating anilox roller, comprising a base roller, a coating disposed on the base roller, and an anilox pit evenly disposed on the coating. The anilox pit is characterized in that the bottom of the anilox pit is provided with staggered grooves, the width of which ranges from 2 micrometers to 6 micrometers.
[0006] Preferably, the depth of the trench is in the range of 1 micrometer to 6 micrometers.
[0007] Preferably, the interval between adjacent trenches is in the range of 2 micrometers to 3 micrometers.
[0008] Preferably, the width of the trench is in the range of 3 micrometers to 5 micrometers.
[0009] Preferably, the depth of the trench is in the range of 2 micrometers to 3 micrometers.
[0010] Preferably, the trench includes a first trench and a second trench, wherein there are multiple first trenches arranged in parallel to each other, and there are multiple second trenches arranged in parallel to each other, and the first trenches and the second trenches are intersected.
[0011] Preferably, the opening direction of the first groove is parallel to one side of the mesh pit, and the opening direction of the second groove is parallel to the other side of the mesh pit.
[0012] Preferably, the depth of the first trench is greater than the depth of the second trench.
[0013] The application employs the above technical solution and has at least the following beneficial effects:
[0014] The viscous slurry coating anilox roller includes a base roller, a coating layer disposed on the base roller, and anilox pits uniformly disposed on the coating layer. The bottom of the anilox pits is provided with staggered grooves, the width of which ranges from 2 micrometers to 6 micrometers. By providing staggered grooves at the bottom of the anilox pits, the adhesion between the slurry entering the pits and the bottom of the pits is reduced, making the slurry easier to transfer and thus improving the yield.
[0015] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0020] A specific embodiment of this utility model provides a viscous slurry coating anilox roller, including a base roller, a coating layer disposed on the base roller, and an anilox groove evenly distributed on the coating layer, in conjunction with an appendix. Figure 1 The bottom structure of the mesh pit is shown in the diagram. The bottom of the mesh pit is provided with staggered grooves, the width of which ranges from 2 micrometers to 6 micrometers.
