Description

Technical Field

[0001] This utility model relates to the field of ceramic processing equipment technology, and in particular to a ceramic blank rolling mill for rapid demolding. Background Technology

[0002] Ceramic blanks refer to the raw, unsintered blanks formed during the ceramic production process. They are characterized by low strength and fragility, requiring further processing and high-temperature firing to reach the final product. Roll forming, a crucial process for shaping ceramic blanks, is widely used in daily-use ceramics, architectural ceramics, and industrial ceramics. It involves applying pressure to a rotating clay blank using a roller, causing it to conform evenly to the mold and achieve the desired shape and thickness. This process offers advantages such as high forming efficiency and precise wall thickness control, making it an indispensable part of modern ceramic manufacturing.

[0003] Utility model patent CN 215618809 U discloses a ceramic blank rolling machine, including a processing table, a column, a motor drive system, and a rolling head assembly. It can achieve horizontal movement and rotation of the rolling head, adapting to the rolling requirements of ceramic blanks with different inner diameters and effectively improving wall thickness uniformity. However, in practical applications, it has been found that the device lacks any demolding assistance structure, making it difficult to smoothly remove the ceramic blank from the mold after rolling. Often, repeated manual tapping or forced peeling with tools is required, which is not only inconvenient and inefficient but also easily causes cracking or edge defects in the blank, seriously affecting the product qualification rate.

[0004] Therefore, to address the shortcomings of existing technologies, we urgently need a rapid demolding ceramic green body rolling mill to solve this problem. This new rolling equipment should, while maintaining the original rolling precision and adjustment flexibility, integrate a highly efficient and stable demolding auxiliary mechanism, significantly improving demolding speed and success rate, reducing green body breakage rate, and minimizing manual intervention. This will comprehensively improve the production efficiency and product quality of ceramic green bodies, better meet the urgent needs of the ceramic manufacturing industry for efficient and intelligent equipment, and provide strong support for the technological upgrading of ceramic forming processes.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Example 1

[0024] Please see Figure 1-5As shown, a ceramic blank rolling mill for rapid demolding in this embodiment includes a processing table 1 and a mounting frame 2 connected to the top of the processing table 1. A rolling head 3 is provided at the bottom of the mounting frame 2, and a lifting module is connected to the top of the rolling head 3. A horizontal moving module is connected to the inner top of the mounting frame 2, and the output end of the horizontal moving module is connected to the lifting module.

[0025] The top of the processing table 1 is provided with a placement cylinder 5. The bottom center of the placement cylinder 5 is connected to the top of the processing table 1 through a drive component. The bottom edge of the placement cylinder 5 is provided with a rotating support structure that cooperates with the top of the processing table 1.

[0026] The bottom of the placement cylinder 5 is provided with a demolding pushing structure, and the inner ring of the placement cylinder 5 is provided with several clamping plates 8. The clamping plates 8 are connected to the inner wall of the placement cylinder 5 through a horizontal pushing structure.

[0027] In operation, this rapid demolding ceramic blank rolling machine first places the blank to be processed into the placement cylinder 5 on top of the processing table 1. The drive assembly is then activated, causing the placement cylinder 5 to rotate the blank. Simultaneously, the horizontal movement module on the mounting frame 2 begins operation. Its output end is connected to the lifting module, which controls the rolling head 3 to move up and down, coordinating with the blank's rotation to complete the rolling process. After rolling, the demolding push structure is activated. This structure, located at the bottom inner part of the placement cylinder 5, applies upward force through a push rod or hydraulic device, uniformly pushing upwards onto the bottom of the ceramic blank. Simultaneously, several clamping plates 8 are connected to the inner wall of the placement cylinder 5 via the horizontal push structure. During demolding, they synchronously contract towards the center and clamp the outer wall of the blank, preventing tilting or slippage during ejection, thus achieving stable and rapid demolding. Furthermore, a rotating support structure is located at the bottom edge of the placement cylinder 5, cooperating with the top of the processing table 1 to ensure the stability and positioning accuracy of the placement cylinder 5 during high-speed rotation, preventing vibration from affecting the rolling quality.

[0028] Example 2

[0029] Please see Figure 1-5 As shown in this embodiment, a rapid demolding ceramic blank rolling mill includes a drive assembly comprising a drive motor 7 mounted on the bottom of the processing table 1. The output end of the drive motor 7 is connected to the bottom of the placement cylinder 5. Specifically, through the connection between the drive motor 7 and the bottom of the placement cylinder 5, the drive motor 7 is mounted on the bottom of the processing table 1 and directly drives the placement cylinder 5 to rotate, ensuring the stability and consistency of the clay blank during the rolling process. This design simplifies the power transmission path, reduces energy loss and the risk of mechanical failure, and improves the operating efficiency and reliability of the equipment.

[0030] The top of the processing table 1 is provided with a rotating groove 6. The rotating support structure includes several support wheels 4 that mate with the interior of the rotating groove 6. The outer ring of each support wheel 4 is rotatably connected to a rotating seat. The top of the rotating seat is rotatably connected to the bottom of the placement cylinder 5 via a rotating shaft. Specifically, through the arrangement of the rotating groove 6, support wheels 4, and rotating seat, multiple support wheels 4 are provided within the rotating groove 6 on the top of the processing table 1. These support wheels 4 are connected to the rotating shaft at the bottom of the placement cylinder 5 via the rotating seat, ensuring that the placement cylinder 5 remains stable and accurately positioned during high-speed rotation. This structure reduces frictional resistance, minimizes wear, extends the service life of the equipment, and improves the precision and quality of roll forming.

[0031] Example 3

[0032] Please see Figure 1-5 As shown in this embodiment, a ceramic blank rolling mill for rapid demolding includes a horizontal pushing structure comprising a pushing cylinder 10 connected to the outer ring of the placement cylinder 5 and a moving plate 9 disposed on one side of the clamping plate 8. The output end of the pushing cylinder 10 is connected to the moving plate 9, and one side of the clamping plate 8 is connected to the moving plate 9 via a horizontal elastic structure. Specifically, through the coordinated arrangement of the pushing cylinder 10, the moving plate 9, the clamping plate 8, and the horizontal elastic structure, during the demolding process, the pushing cylinder 10 drives the moving plate 9 to move towards the center, causing the clamping plate 8 to simultaneously contract and clamp the outer wall of the blank. The round rod 11 and the compression spring 12 in the horizontal elastic structure provide appropriate elastic buffering to prevent excessive clamping force from causing breakage of the blank. This structure not only ensures the stability of the blank during demolding but also effectively prevents surface damage caused by improper clamping, thereby improving the yield.

[0033] The bottom of the placement cylinder 5 has an annular groove 13, and both sides of the annular groove 13 have circular grooves 14. The demolding pushing structure includes two lifting cylinders 15 installed at the bottom of the placement cylinder 5 and two circular plates 17 set inside the circular grooves 14. A pushing ring 18 connected to the two circular plates 17 is set inside the annular groove 13. The output end of the lifting cylinder 15 is connected to the adjacent circular plate 17. A guide rod 16 with one end sliding through the placement cylinder 5 is fixedly connected to both sides of the bottom of the pushing ring 18. Specifically, through the arrangement of the lifting cylinder 15, annular groove 13, circular groove 14, circular plates 17, and pushing ring 18, during the demolding stage, the lifting cylinder 15 drives the circular plate 17 upward, thereby driving the pushing ring 18 upward, applying a uniform ejection force to the bottom of the ceramic blank. This design achieves a fast and stable demolding operation, avoiding damage to the blank that may be caused by traditional manual or hammering demolding methods, significantly improving the demolding success rate and production efficiency.

[0034] The horizontal elastic structure comprises several round rods 11 and compression springs 12. One end of each round rod 11 is fixedly connected to the side wall of the clamping plate 8, and the other end slides through the moving plate 9. One end of each compression spring 12 is connected to the side wall of the clamping plate 8, and the other end is connected to the side wall of the moving plate 9. Specifically, through the horizontal elastic structure composed of round rods 11 and compression springs 12, round rods 11 are fixedly connected to one side of the clamping plate 8, and the other end slides through the moving plate 9, with compression springs 12 positioned between them. When the clamping plate 8 moves towards the center to clamp the blank, the compression springs 12 provide necessary elastic compensation to ensure that the clamping force is moderate, neither damaging the blank due to excessive tightness nor causing clamping failure due to excessive looseness. This design optimizes the force distribution during clamping, further improving the safety and stability of the demolding operation.

[0035] This rapid demolding ceramic blank rolling machine includes a processing table 1, a mounting frame 2, a rolling head 3, a lifting module, a horizontal moving module, a placement cylinder 5, a drive assembly, a rotating support structure, a demolding pushing structure, a clamping plate 8, a horizontal pushing structure, and its elastic components. In actual use, the operator first places the clay blank to be processed into the placement cylinder 5, then starts the drive motor 7, which drives the placement cylinder 5 to rotate via a bottom connection. Simultaneously, the horizontal moving module drives the lifting module to move the rolling head 3 laterally and coordinate with its up-and-down movement, applying uniform pressure to the rotating clay blank to complete the rolling forming operation. After the rolling process is completed, the demolding stage begins: the lifting cylinder 15 actuates, pushing the ring 18 upward along the circular groove 14, and causing the pushing ring 18 to rise from the circular groove 13, applying a uniform ejection force to the bottom of the blank; simultaneously, the pushing cylinder 10 drives the moving plate 9 to move towards the center, causing the clamping plate 8 to retract synchronously and clamp the outer wall of the blank, preventing it from sliding or tilting and falling off; during the clamping process, one side of the clamping plate 8 is slidably connected to the moving plate 9 through the circular rod 11, and the compression spring 12 provides a buffering effect to ensure that the clamping force is moderate and to avoid damage to the blank due to excessive clamping. The entire rolling and demolding process is carried out in a highly stable support environment. The top of the processing table 1 is provided with a rotating groove 6, in which the support wheel 4 is embedded and connected to the bottom rotating shaft of the placement cylinder 5 through a rotating seat, ensuring rotational stability and positioning accuracy.

[0036] This technical solution effectively solves the problems of difficult demolding, excessive manual intervention, and easy breakage of raw blanks caused by the lack of demolding assistance mechanisms in existing rolling equipment through the close cooperation between various structures. The drive motor 7 directly drives the placement cylinder 5 to rotate, improving power transmission efficiency and operational stability; the design of the support wheel 4 and rotating seat in the rotating support structure reduces frictional resistance, improves rotational accuracy, and extends equipment life; the demolding pushing structure achieves uniform ejection through the lifting cylinder 15 and the pushing ring 18, avoiding cracking caused by excessive local force; the clamping plate 8, combined with the pushing cylinder 10 and the moving plate 9, achieves automatic clamping, improving the controllability and safety of the demolding process; the round rod 11 and the compression spring 12 in the horizontal elastic structure further optimize the force distribution during the clamping process, preventing surface damage caused by excessive or uneven clamping force.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
