When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, and "several" means one or more, unless otherwise explicitly specified.

[0032] Reference Figures 1 to 4This application provides a coating die head, comprising a die head body formed by an upper die head 10 and a lower die head 20, a storage cavity 21 disposed within the die head body for containing slurry, and a slit outlet 30 disposed at the front end of the die head body and communicating with the storage cavity 21. In this embodiment, a receiving groove 40 is provided at the front end of the die head body and outside the slit outlet 30. The receiving groove 40 is disposed along the length direction of the die head body and passes through both ends of the die head body. The coating die head also includes a plurality of stops 50, which slide into the receiving groove 40 from the ends of the receiving groove 40, and the stops 50 can be freely combined and disposed within the receiving groove 40.

[0033] In this embodiment, a receiving groove 40 is formed by extending the front end of the die head body, and a baffle 50 is freely arranged in the receiving groove 40. The baffle 50 blocks the slit outlet 30 and adjusts the liquid outlet width. In this way, basebands of different widths can be coated. The structure is simple and easy to use.

[0034] Specifically, the upper die head 10 extends forward at its front end and above the slit outlet 30 to form a top eave 11, which is positioned along the length of the upper die head 10. A bottom plate 22 is inclinedly positioned at the front end of the lower die head 20 and below the slit outlet 30, with the bottom plate 22 also positioned along the length of the lower die head 20. The top eave 11, the front end face of the upper die head 10, the front end face of the lower die head 20, and the bottom plate 22 together form a receiving groove 40. That is, the receiving groove 40 surrounds the outside of the slit outlet 30, serving to fix the stop block 50, which in turn blocks the slit outlet 30.

[0035] Specifically, in this embodiment, the bottom surface of the top eaves 11 is horizontal, the bottom plate 22 is inclined upward, and the receiving groove 40 is wider at the closed end on the side of the slit and narrower at the open end away from the slit. With this structure, the receiving groove 40 is wider inside and narrower outside, which prevents the stop block 50 from falling outward after being placed in the receiving groove 40.

[0036] Specifically, the stop block 50 includes a stop block body 51 and a locking block 52 disposed on the outside of the stop block body 51. The shape of the stop block body 51 matches the cross-sectional shape of the receiving groove 40. During installation, the stop block body 51 is embedded in the receiving groove 40, while the locking block 52 is locked on the outside of the top wall of the receiving groove 40.

[0037] In this embodiment, there are four baffles 50, with two at each end of the receiving groove 40. In this way, the baffles 50 block the slit outlet 30 from both ends, adjusting the liquid outlet width. Of course, the number of baffles 50 can be freely combined when coating different basebands; for example, one, three, or more baffles can be placed at each end of the receiving groove 40.

[0038] In this embodiment, the top of the upper die head 10 is also provided with a pressure detection device 60 that extends to the storage cavity 21. The pressure detection device 60 can collect the pressure signal inside the storage cavity 21 in real time. When there is slurry or no slurry in the storage cavity 21, the pressure detection device 60 can collect different signals and feed them back to the coating equipment, so that the operator can adjust the slurry in time, thereby improving production efficiency and production yield.

[0039] In this embodiment, the material storage cavity 21 is located on the top surface of the lower die head 20, the bottom of the upper die head 10 is a plane, the upper die head 10 covers the lower die head 20, and the upper die head 10 and the lower die head 20 are fixedly connected by a vertically inserted connector (not labeled in the figure).

[0040] In this embodiment, the two ends of the die head body are also provided with fixing shafts 70 for fixing it. The fixing shafts 70 at both ends realize the fixed connection between the die head body and the external power component. At the same time, the setting angle of the die head body can be adjusted by the fixing shafts 70 through the drive of the external power component.

[0041] In this embodiment, a temperature regulating component (not shown in the figure) is also provided on the die head body. When the temperature of the slurry in the storage chamber 21 changes, the slurry flows out of the slit outlet 30, causing the slit outlet 30 to expand or contract, resulting in deformation and affecting the distance between it and the baseband (not shown in the figure). By providing the temperature regulating component, the temperatures of the upper die head 10 and the lower die head 20 can be monitored. When the slit outlet 30 deforms at different temperatures, the distance between the coating die head and the baseband can be adjusted to regulate the coating weight and thickness, maintaining coating consistency.

[0042] This application embodiment also provides a coating device (not shown in the figure), including a worktable, a coating die disposed on the worktable, a slurry flowing inside the coating die, and a baseband conveying device disposed on the worktable and close to the coating die, the slit outlet 30 of the coating die facing the baseband conveying device, and the coating die is the aforementioned coating die.

[0043] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
