Description

Technical Field

[0001] This utility model relates to the field of ceramic thin film preparation equipment, and in particular to a novel casting box for casting molding process. Background Technology

[0002] Casting is a widely used process for preparing ceramic thin films, playing a crucial role in the industrial production of ceramic thin films. The casting box, as a key component of the casting machine, directly affects the quality of the final ceramic film, especially its uniformity. Structurally, the casting box is directly attached to the roller of the PET film; this design lacks an effective mechanism to ensure casting uniformity. With continuous technological advancements, the market demands higher standards for the uniformity and thickness of the ceramic film; however, existing casting equipment struggles to meet these high requirements. Regarding the feeding structure, the original design used a guide pipe to directly introduce the slurry into the casting box. In actual production, due to air pressure fluctuations during slurry transport, the slurry impacts the already cast film slurry upon entering the casting box. This impact disrupts the uniformity of the slurry, resulting in inconsistent thickness and poor surface flatness at different locations on the film, thus severely affecting the overall quality of the ceramic film. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention aims to provide a novel casting box to improve the uniformity and quality of ceramic thin film preparation.

[0004] To achieve the above objectives, this utility model proposes a novel casting box, comprising two symmetrically arranged end limiting blocks and a bottom limiting block arranged between the two end limiting blocks. The bottom limiting block is inclined, with its end away from the roller being higher and its end closer to the roller being lower. The bottom limiting block, the two end limiting blocks, and the roller cooperate to form a box-shaped structure. It also includes a deposition box, which is V-shaped and arranged on the upper inner side of the box-shaped structure, close to the bottom limiting block. Its width matches the distance between the inner walls of the two end limiting blocks. The end of the deposition box away from the bottom limiting block is higher than the end close to the bottom limiting block, and the end close to the bottom limiting block has an outward flange. The outward flange is perpendicular to the bottom limiting block, and a number of holes are densely arranged on the surface of the outward flange. A slurry passage is reserved between the outer wall of the deposition box below the holes and the bottom limiting block.

[0005] In the above scheme: symmetrical limiting posts are provided on the inner walls of the two side-end limiting blocks. The deposition box abuts against the bottom limiting block through its outward flange and is supported on the two limiting posts by its outer wall on the side away from the bottom limiting block, thus fixing the entire box to the upper inner side of the box-shaped structure. This dual positioning method ensures that the deposition box is accurately installed on the upper inner side of the box-shaped structure, avoiding structural instability caused by installation deviation, and ensuring that the deposition box will not shake or shift during operation. Furthermore, installation and disassembly are convenient. When cleaning, maintenance, or replacement of the deposition box is required, operators can quickly and accurately remove and reinstall the deposition box from the limiting structure, reducing maintenance time and difficulty.

[0006] In the above design, the diameter of the hole is 0.5 mm. This diameter is carefully designed to precisely control the leakage rate and flow rate of the slurry through the hole. This size is neither too large, causing a large amount of slurry to gush out in a short time, resulting in local slurry accumulation and affecting the uniformity of subsequent flow; nor too small, causing the slurry to leak too slowly or even cause blockage. This ensures that the slurry leaks continuously at a stable and appropriate rate, guaranteeing uniform flow into the box-shaped structure.

[0007] In the above solution: the two side-end limiting blocks are provided with obliquely extending U-shaped openings, and the two U-shaped openings on both sides are symmetrical. The bottom-end limiting block is engaged between the two U-shaped openings and locked with a nut. The symmetrical U-shaped openings provide precise installation guidance for the bottom-end limiting block, allowing for quick installation.

[0008] In the above scheme: the side-end limiting blocks are respectively provided with arc-shaped opening structures for engaging with the roller and arc-shaped opening structures for engaging with the casting knife. The operator can use the arc-shaped opening structures to quickly and accurately position the casting box to the corresponding position, and the slurry can pass through the gap between the casting knife and the roller to form a thin layer of ceramic film.

[0009] The beneficial effects of this utility model are:

[0010] By setting up a "V"-shaped deposition box, the ceramic slurry first accumulates in the deposition box. After reaching a certain depth, it leaks through the densely arranged holes on its outer edge. The leaked ceramic slurry flows slowly along the inner wall of the bottom limiting block, and can flow evenly into the box-shaped structure formed by the bottom limiting block, the two side limiting blocks and the casting machine roller. Finally, it adheres evenly to the PET film, avoiding the impact of the ceramic slurry on the cast film and effectively ensuring the uniformity of the cast film. Attached Figure Description

[0012] Figure 2 This is a schematic diagram of the installation of the sedimentation box.

[0013] Figure 3 This is a schematic diagram of the deposition box. Detailed Implementation

[0014] like Figure 1 As shown in Figure 3, a novel casting box mainly consists of two side end limiting blocks 1 arranged symmetrically on the left and right, a bottom end limiting block 2 arranged between the two side end limiting blocks 1, and a deposition box 4.

[0015] The bottom limiting block 2 is arranged at an angle, with the end away from the roller 3 being higher and the end close to the roller 3 being lower. The bottom limiting block 2 and the two side limiting blocks 1 cooperate with the roller to form a box-shaped structure.

[0016] Specifically, the two end limit blocks 1 are provided with obliquely extending U-shaped openings, which are symmetrical on both sides. The bottom limit block 2 is engaged between the two U-shaped openings and locked with nuts. The symmetrical U-shaped openings provide precise installation guidance for the bottom limit block 2, allowing for quick installation.

[0017] The sediment box 4 is V-shaped and is located on the upper inner side of the box-shaped structure, close to the bottom limiting block 2. Its width matches the distance between the inner walls of the two side limiting blocks 1.

[0018] The end of the sedimentation box 4 away from the bottom limiting block 2 is higher than the end near the bottom limiting block 2, and the end near the bottom limiting block 2 is provided with an outward flange 41. The outward flange 41 is perpendicular to the bottom limiting block 2, and a number of holes 5 are densely arranged on the surface of the outward flange 41. A slurry passage is reserved between the outer wall of the sedimentation box 4 below the holes 5 and the bottom limiting block 2.

[0019] The diameter of the hole is 0.5mm. This diameter is carefully designed to precisely control the leakage rate and flow rate of the slurry through the hole. This size is neither too large, which would cause a large amount of slurry to gush out in a short time, resulting in localized slurry accumulation and affecting the uniformity of subsequent flow; nor too small, which would cause the slurry to leak too slowly or even cause blockage. This ensures that the slurry leaks continuously at a stable and appropriate rate, providing a strong guarantee for uniform flow into the box-shaped structure.

[0020] Specifically, symmetrical limiting posts 6 are provided on the inner walls of the two end limiting blocks 1. The deposition box 4 abuts against the bottom limiting block 2 through its outward flange 41, and is supported on the two limiting posts 6 by its outer wall on the side away from the bottom limiting block 2, thus fixing the entire box to the upper inner side of the box-shaped structure. This dual positioning method can ensure that the deposition box 4 is accurately installed on the upper inner side of the box-shaped structure, avoiding structural instability caused by installation deviation, and ensuring that the deposition box 4 will not shake or shift during the operation of the entire casting box. Moreover, it is easy to install and disassemble. When the deposition box 4 needs to be cleaned, repaired or replaced, the operator can quickly and accurately remove the deposition box 4 from the limiting structure and install it back, reducing maintenance time and difficulty.

[0021] The side-end limiting block 1 is provided with an arc-shaped opening structure 8 for engaging with the roller 3 and an arc-shaped opening structure 8 for engaging with the casting knife 7. The operator can use the arc-shaped opening structure 8 to quickly and accurately position the casting box to the corresponding position. The slurry can pass through the gap between the casting knife 7 and the roller 3 (both casting knife 7 and roller 3 are equipment on the casting machine) to form a thin layer of ceramic film.
