Description

Technical Field

[0001] This utility model relates to the field of ceramic casting technology, and in particular to a casting machine for preparing ceramic substrates. Background Technology

[0002] Ceramic substrates are generally produced using the casting method. When casting the slurry, a casting doctor blade is needed to smooth the slurry. The quality of the doctor blade directly determines the surface quality of the ceramic substrate.

[0003] In the actual production process of ceramic substrates, due to the different thicknesses and viscosities of the casting slurry, the casting slurry undergoes self-flow after being leveled by the doctor blade, resulting in an uneven surface structure of the ceramic substrate. Utility Model Content

[0004] In view of this, it is necessary to provide a casting molding machine for preparing ceramic substrates to solve the problem that existing scrapers cannot ensure that the ceramic substrate maintains a uniform structure after smoothing the casting slurry.

[0005] This utility model provides a casting machine for preparing ceramic substrates, comprising:

[0008] Furthermore, the electromagnetic heating plate includes, from bottom to top, an induction metal layer, an excitation module, and a structural support layer. The upper and lower sides of the excitation module are fixedly connected to the induction metal layer and the structural support layer, respectively. The structural support layer is fixedly connected to the side of the scraper. The induction metal layer can be heated by the excitation module.

[0009] Furthermore, the excitation module includes an electromagnetic coil layer and an insulating layer surrounding the electromagnetic coil layer. The insulating layer is connected to the induction metal layer and the structural support layer, respectively. The electromagnetic coil layer can excite the induction metal layer to heat up uniformly.

[0010] Furthermore, the heating unit also includes a reinforcing plate. The electromagnetic heating plate is arranged parallel to the conveying assembly. One side of the electromagnetic heating plate is fixedly connected to the scraper. The reinforcing plate is arranged perpendicular to the electromagnetic heating plate. Both ends of the reinforcing plate are fixedly connected to the scraper and the electromagnetic heating plate, respectively.

[0011] Furthermore, the lifting frame includes brackets and a spiral component disposed on both sides of the conveying assembly. The two brackets are disposed opposite to each other and connected to the conveying assembly. The two ends of the scraper are slidably engaged in the two brackets respectively.

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0028] This embodiment describes a casting machine for preparing ceramic substrates, which relates to the field of ceramic casting technology. By modifying the scraper 210, the height of the scraper 210 relative to the ceramic slurry can be adjusted, and the surface of the ceramic slurry can be initially thermally solidified, reducing the fluidity of the ceramic slurry, reducing the subsequent self-flow of the ceramic slurry, and ensuring the uniformity of the ceramic plate structure.

[0029] Please see Figures 1 to 7 This embodiment of a casting molding machine for preparing ceramic substrates includes a conveying assembly 100 and a leveling assembly 200. The conveying assembly 100 can convey ceramic slurry along a predetermined direction to promote the forming of the ceramic substrate. The leveling assembly 200 can preheat the ceramic slurry while leveling it, thereby thermally curing the ceramic slurry.

[0030] The leveling assembly 200 includes a scraper 210, a lifting frame 220, and a heating unit 230. The scraper 210 is connected to the conveying assembly 100 via the lifting frame 220. The lifting frame 220 can adjust the height of the scraper 210 relative to the conveying assembly 100, thereby changing the depth to which the scraper 210 cuts into the ceramic slurry and adjusting the thickness of the ceramic slab. The heating unit 230 includes an electromagnetic heating plate 231, which is connected to the scraper 210. The electromagnetic heating plate 231 can heat the ceramic slurry leveled by the scraper 210, solidify the surface of the ceramic slurry, reduce its fluidity, decrease subsequent self-flow, and ensure the uniformity of the ceramic slab structure.

[0031] In some embodiments, please refer to Figure 6 The electromagnetic heating plate 231 includes, from bottom to top, an induction metal layer 231a, an excitation module 231b, and a structural support layer 231c. The upper and lower sides of the excitation module 231b are fixedly connected to the induction metal layer 231a and the structural support layer 231c, respectively. The induction metal layer 231a, the excitation module 231b, and the structural support layer 231c are tightly integrated, making the overall structure compact and easy to integrate into the scraper 210 system of the casting machine.

[0032] The structural support layer 231c is fixedly connected to the side of the scraper 210, so that the entire heating plate is firmly attached to the scraper 210 without the need for additional complex fixing devices, which reduces the difficulty and cost of equipment modification.

[0033] The excitation module 231b generates an alternating magnetic field, causing the induction metal layer 231a to heat up rapidly, reaching the set temperature in a short time and maintaining a constant temperature. Compared with traditional resistance heating, electromagnetic induction heating has a faster response and higher temperature control accuracy.

[0034] Temperature fluctuations can affect the fluidity of the slurry and the uniformity of the coating thickness, but the precise temperature control of the electromagnetic heating plate 231 can avoid this problem and improve the consistency of coating quality.

[0035] After the induction metal layer 231a is heated by the excitation module 231b, the surface temperature of the slurry can be effectively increased, so that it is partially pre-dried or thickened when it is cast under the scraper 210, reducing the diffusion of the slurry after casting and improving the clarity of the coating boundary and the uniformity of the thickness.

[0036] In some embodiments, please continue reading Figure 6The excitation module 231b includes an electromagnetic coil layer 231b1 and an insulating layer 231b2 surrounding the electromagnetic coil layer 231b1. The insulating layer 231b2 located below the electromagnetic coil layer 231b1 is connected to the induction metal layer 231a, and the insulating layer 231b2 located above the electromagnetic coil layer 231b1 is connected to the structural support layer 231c. When current flows through the electromagnetic coil layer 231b1, the insulating layer 231b2 can block the electrical connection between the electromagnetic coil layer 231b1 and the induction metal layer 231a and the structural support layer 231c, thereby avoiding the risk of leakage.

[0037] It should be noted that: the electromagnetic coil layer 231b1 contains multiple sets of coils, and alternating current can be passed through the coils to heat the induction metal layer 231a, which is made of alloy steel.

[0038] In some embodiments, please refer to Figure 5 The heating unit 230 also includes a reinforcing plate 232. An electromagnetic heating plate 231 is arranged parallel to the conveying assembly 100. One side of the electromagnetic heating plate 231 is fixedly connected to the scraper 210. The reinforcing plate 232 is arranged perpendicular to the electromagnetic heating plate 231, and both ends of the reinforcing plate 232 are fixedly connected to the scraper 210 and the electromagnetic heating plate 231, respectively. The reinforcing plate 232 enhances the structural rigidity. By fixing both ends of the reinforcing plate 232 to the scraper 210 and the electromagnetic heating plate 231, deformation or displacement of the heating plate due to temperature changes, vibration, or mechanical pressure during operation can be effectively prevented, ensuring the stability of the heating plate during operation.

[0039] During the heating process, the temperature of the electromagnetic heating plate 231 may change, causing the material to expand. The reinforcing plate 232, as a supporting structure, can help alleviate the stress caused by thermal expansion, reduce the risk of the heating plate affecting the operation of the scraper 210 due to thermal deformation, and ensure the relative position and accuracy between the scraper 210 and the heating plate.

[0040] In some embodiments, please refer to Figure 7 The lifting frame 220 includes brackets 221 and a screw 222 disposed on both sides of the conveying assembly 100. The two brackets 221 are arranged opposite to each other and connected to the conveying assembly 100. The two brackets 221 serve as a support base and can be connected to both ends of the scraper 210. The two ends of the scraper 210 are slidably engaged in the two brackets 221 respectively. The brackets 221 provide stable support and guidance for the scraper 210, making it less likely for the scraper 210 to deviate from its trajectory during movement and preventing the scraper 210 from tilting or deforming.

[0041] The auger 222 works in conjunction with the scraper 210 to drive the scraper 210 to rise and fall, making operation simpler and more efficient. Users only need to adjust the auger 222 (such as an electric screw or a manual auger drive) to easily and precisely adjust the position of the scraper 210, reducing operation time and manual intervention.

[0042] In the specific implementation process, a groove is provided in the bracket 221, and the end of the scraper 210 is slidably engaged in the groove. The groove is relatively vertical, and the scraper 210 can move relative to the groove to adjust the depth of the scraper 210 cutting into the ceramic slurry. The spiral component 222 is specifically a bolt. The middle part of the bolt is threadedly connected to the bracket 221, and the lower end of the bolt extends into the groove. The bottom of the lower end of the bolt is rotatably connected to the end of the scraper 210 and axially locked. By rotating the bolt, one end of the scraper 210 can be driven to move relative to the groove, effectively adjusting the depth of the scraper 210 cutting into the ceramic slurry.

[0043] As a further embodiment, the lifting frame 220 also includes a level 223, which is mounted on the scraper 210. The two ends of the scraper 210 can move independently under the action of the spiral component 222, which can easily cause the blades of the scraper 210 to tilt relative to each other. The installation of the level 223 ensures that the scraper 210 remains horizontal during the lifting process. The scraper 210 of a ceramic casting machine typically requires very precise angles and levelness. The level 223 can detect in real time whether the scraper 210 is parallel to the substrate surface, thereby avoiding uneven coating or other quality defects caused by unevenness or angular deviation of the scraper 210.

[0044] By monitoring the horizontal status of the scraper 210 in real time, the level 223 can help the operator adjust the position or angle of the scraper 210 to ensure the thickness and uniformity of the ceramic plate.

[0045] As a further embodiment, a scale is provided on both sides of the slide groove of the bracket 221, and the spiral component 222 can determine the height of the end of the scraper 210 according to the markings on the scale.

[0046] In some embodiments, please refer to Figure 5 The scraper 210 is inclined relative to the conveying assembly 100. The scraper 210 is provided with a scraping edge 211 relative to the feeding direction of the ceramic slurry. The scraping edge 211 on the scraper 210 helps to accurately control the thickness of the ceramic slurry. By effectively scraping away excess slurry, the uniformity of the coating thickness is ensured.

[0047] The angle between the inclined scraper 210 and the conveying assembly 100 allows the scraper 210 to apply pressure more evenly to the surface of the ceramic slurry during operation, which helps to achieve uniform slurry coating. The scraping blade 211 on the scraper 210 ensures effective control of the slurry during the scraping process, preventing too much or too little slurry from adhering to the substrate surface.

[0048] In some embodiments, please refer to Figures 1 to 3 The conveying assembly 100 includes a linear conveyor belt 110, baffles 120, and a drive unit 130. The two baffles 120 are disposed on both sides of the linear conveyor belt 110. The drive unit 130 can control the baffles 120 to move closer or further away from each other, change the distance between the two baffles 120, thereby adjusting the distribution width of the ceramic slurry and directly controlling the width of the ceramic plate.

[0049] In the specific implementation process, the drive unit 130 can be electrically pushed, and the output end of the electric push rod is connected to the baffle 120 to precisely control the moving distance of the baffle 120.

[0050] Workflow: First, adjust the drive unit 130 to achieve a suitable width between the two baffles 120. Then, twist the auger 222 to adjust the height of the scraper 210 relative to the linear conveyor belt. Next, energize the electromagnetic coil layer 231b1 to heat the induction metal layer 231a. Finally, pour ceramic slurry onto the linear conveyor belt to obtain a ceramic plate that meets the requirements.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the present utility model.
