Abstract
Description
Technical Field
[0001] This utility model relates to the field of slit extrusion coating die technology, specifically a coating die pad with adjustable ceramic layer. Background Technology
[0002] A key step in lithium battery manufacturing is coating the cathode and anode slurries onto the current collector surface. Existing coating equipment features a distribution channel and central feeding. However, during periodic die head cleaning, slurry can easily overflow from the distribution channel and enter the screw holes of the lower die head, resulting in incomplete cleaning. After the slurry dries, it can cause improper installation of the connecting screws, damaging the threads and affecting the die head installation accuracy, leading to material leakage and other abnormalities. A utility model patent with Chinese patent publication number CN217797047U proposes a lithium battery coating mold with a sealing spacer. This mold uses a sealing spacer on the outside of the fasteners connecting the upper and lower die heads to prevent slurry from overflowing from the distribution channel and entering the screw holes of the lower die head during periodic die head cleaning. This prevents incomplete cleaning, improper installation of the connecting screws after the slurry dries, damaging the threads and affecting the die head installation accuracy, leading to material leakage and other abnormalities. However, the gasket used in the aforementioned patent is singular and its application scope is not broad enough. Therefore, this utility model proposes a coating mold gasket with adjustable ceramic layer. Utility Model Content
[0003] Technical problems to be solved
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a coating mold gasket with adjustable ceramic layer.
[0005] Technical solution
[0006] To achieve the above objectives, this utility model provides the following technical solution: a ceramic layer adjustable coating mold gasket, comprising a gasket body, wherein the gasket body has forward-protruding and symmetrically arranged left and right ends, a slurry outlet area is provided between the left and right ends, and a middle protruding area is provided in the middle between the left and right ends. Each of the left, right, and middle protruding areas has a mounting groove, and a left adjustment block, a middle adjustment block, and a right adjustment block are respectively tightly fitted into the mounting groove. Each of the left, middle, and right adjustment blocks has a ceramic flow channel. Both the middle and right adjustment blocks have ceramic material outlets on one side. The left, middle, and right adjustment blocks each have an outlet protrusion on the side of the ceramic material outlet. By designing different island sizes, the coverage width of the ceramic coating can be adjusted (the island size can be changed to adjust the width of the ceramic coating). Changing the size of H in the attached figure can adjust the thickness of the ceramic layer. Changing the size of W in the attached figure can adjust the width of the ceramic layer. Furthermore, by setting different protrusion heights of the outlet protrusions, the thickness of the ceramic material can be adjusted. The higher the protrusion, the closer it is to the substrate layer, and the thinner the coating; conversely, the lower the protrusion, the thicker the coating.
[0007] Preferably, the outlet boss and the edge of the slurry outlet area are provided with islands. By designing different island sizes, the coverage width of the ceramic coating can be achieved. Furthermore, by setting different protrusion heights of the outlet boss, the thickness of the ceramic material can be adjusted.
[0008] Preferably, the slurry outlet area is provided with a flow-blocking block installation area.
[0009] Preferably, the gasket body is provided with a flow-blocking groove on one side of the left adjustment block, the middle adjustment block and the right adjustment block.
[0010] Preferably, the gasket body is fixedly connected to the bottom of the upper mold of the coating mold by a pressure strip.
[0011] Beneficial effects:
[0012] Compared with existing technologies, this adjustable coating mold gasket for ceramic layers has the following advantages:
[0013] This invention can achieve different coverage widths for ceramic coating by designing different island sizes, and can adjust the thickness of ceramic material by setting different protrusion heights of the outlet bosses. Attached Figure Description

A ceramic material outlet 11 is provided on one side of each of the left adjustment block 7, middle adjustment block 8, and right adjustment block 9. An outlet boss 12 is provided on the side of the ceramic material outlet 11. By designing different islands 13, the coverage width of the ceramic coating (island size; by changing its size, the width of the ceramic coating can be adjusted) can be achieved, changing the attached... Figure 5 The size of H in the middle can adjust the thickness of the ceramic layer and change the attachment. Figure 5 The size of W can be adjusted to change the width of the ceramic layer, and the thickness of the ceramic material can be adjusted by setting different protrusion heights of the outlet protrusion 12. The higher the protrusion height 12 is, the closer it is to the substrate layer and the thinner the coating is; conversely, the lower the protrusion height 12 is, the thicker the coating is.
[0025] Please refer to the following carefully. Figure 3 , Figure 4 and Figure 5 An island 13 is provided at the edge of the outlet boss 12 and the slurry outlet area 4.

[0027] Working principle: By designing different island sizes (13), the coverage width of the ceramic coating can be achieved (island size, by changing its size, the width of the ceramic coating can be adjusted), thus changing the attachment... Figure 5 The size of H in the middle can adjust the thickness of the ceramic layer and change the attachment. Figure 5 The size of W can be adjusted to change the width of the ceramic layer, and the thickness of the ceramic material can be adjusted by setting different protrusion heights of the outlet protrusion 12. The higher the protrusion height 12 is, the closer it is to the substrate layer and the thinner the coating is; conversely, the lower the protrusion height 12 is, the thicker the coating is.
