Description

Technical Field

[0001] This invention relates to the field of rotating base technology for ceramic manufacturing, and specifically to a rotating base for ceramic craft manufacturing. Background Technology

[0002] In the ceramic making process, throwing and shaping is a key step. The operator needs to accurately place the clay blank in the center of the rotating base to ensure that the finished product has a uniform wall thickness and a stable structure. Beginners usually need to practice for a long time to master the skill of centering. Moreover, there are still errors in manual placement, which can cause the clay blank to rotate off-center, generate centrifugal force, affect the shaping quality, and even cause the clay blank to be thrown out or crack at the bottom. The existing ceramic rotating bases mainly have the following problems: 1. Difficulty in centering: Relies on operator experience, lacks intuitive reference, and results in low placement accuracy; 2. Conflict between anti-slip and cleaning: Although the fixed texture on the surface can enhance adhesion, the clay blank is easy to stick together, making demolding difficult, and mud and water accumulate in the texture, making cleaning inconvenient; 3. Insufficient stability: Centrifugal force during high-speed rotation causes the clay blank to slide or the base to vibrate, affecting the molding quality; 4. Limited functionality: The ability to quickly switch between throwing and unthrowing states results in low efficiency.

[0003] Some high-end equipment uses industrial-grade aluminum alloy packaging turntables, which improve stability through dual bearing design and robust materials, but the cost is high and not suitable for widespread adoption; other methods use visual positioning or mechanically assisted centering, but the structure is complex and the operation is cumbersome, making it difficult to apply conveniently in traditional pottery throwing processes; therefore, this invention provides a rotating base for ceramic processing to solve the above problems. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention provides a rotating base for ceramic manufacturing, which solves the problems of difficulty in centering, contradiction between anti-slip and cleaning, insufficient stability, and limited functionality of traditional ceramic rotating bases.

[0005] To achieve the above objectives, the present invention employs a ceramic manufacturing process for a rotating base, comprising a first base and a second base. The first base is located above the second base, together forming a disc-shaped structure with an open top. A rotating disk is disposed inside the first base, and the surface of the rotating disk is provided with multiple concentrically distributed annular grooves. The diameter of the multiple annular grooves varies from small to large, and paint is applied to the annular grooves. The paint colors in adjacent annular grooves are different. An elastic pad, made of rubber material, is fixedly provided at the upper opening of the annular groove. The rotating disk has a connecting hole inside, and multiple annular grooves are connected through the connecting hole. An external connecting pipe is installed on the outer periphery of the rotating disk, and the external connecting pipe is used to connect an air pump or a suction pump.

[0006] As a further optimization of the above scheme, the depth of the annular groove is 1-3mm, the spacing is 5-15mm, and the cross-section is V-shaped or U-shaped.

[0007] As a further optimization of the above solution, the lower surface of the rotating disk is provided with a first annular guide groove and a second annular guide groove, wherein the first annular guide groove is located in the inner circle of the second annular guide groove and they are arranged concentrically. The upper end of the second base is provided with a limiting protrusion, which is slidably disposed in the second annular guide groove; An installation base is fixedly installed on the inner bottom surface of the second base. An electromagnet is provided on the installation base. The electromagnet is slidably disposed in the first annular guide groove. When the electromagnet is energized, it generates longitudinal and transverse magnetic attraction forces on the rotating disk.

[0008] As a further optimization of the above solution, a piezoelectric force sensor is installed at the bottom of the rotating disk. The piezoelectric force sensor is used to monitor the centrifugal force of the rotating disk and is connected to the electromagnet through a control chip to adjust the current of the electromagnet according to the magnitude of the centrifugal force.

[0009] As a further optimization of the above solution, a drain outlet is provided on one side of the first base, an annular groove is provided at the bottom of the first base, and a rubber plug is installed at the drain outlet.

[0010] As a further optimization of the above solution, a base plate and a top plate are also included. The base plate is fixedly installed at the bottom of the second base, and the top plate is located above the first base. A first slide rail and an LED projection light are installed below the top plate. A first slider is slidably disposed in the first slide rail, a second slide rail is fixedly installed at the bottom of the first slider, a second slider is slidably disposed on the second slide rail, and the sliding direction of the second slider is perpendicular to the sliding direction of the first slider; The bottom of the second slider is connected to a spring telescopic rod, and a wristband is fixedly connected to the bottom of the spring telescopic rod.

[0011] As a further optimization of the above scheme, there is a damping force between the first slider and the first slide rail, and there is a damping force between the second slider and the second slide rail.

[0012] As a further optimization of the above scheme, in the initial state, the elastic pad is in a concave state; when air is injected into the annular groove through the outer pipe, the elastic pad bulges upward and becomes parallel to the upper surface of the rotating disk.

[0013] As a further optimization of the above solution, the elastic pad is provided with a circular hole that penetrates the upper and lower surfaces, and an annular magnetic block is fixedly installed in the middle of the bottom of the elastic pad. An electromagnet is fixedly installed at the bottom of the annular groove. The electromagnet corresponds to the annular magnetic block. When the electromagnet is activated, a magnetic repulsion force is generated between it and the annular magnetic block, causing the elastic pad to bulge upwards to a parallel state.

[0014] As a further optimization of the above solution, a servo motor is also included. The servo motor is fixedly mounted on the upper surface of the base plate, and the upper shaft of the servo motor is fixedly connected to the T-shaped transmission shaft or connected by a magnetic coupler.

[0015] The rotating base for ceramic manufacturing according to the present invention has the following beneficial effects: 1. Quick and accurate centering: By setting concentrically distributed, alternating colored annular grooves on the surface of the rotating disc, an intuitive visual reference system is formed. Operators can quickly judge and adjust the placement position according to the matching degree between the clay blank outline and the annular grooves, significantly reducing the difficulty of centering. It is especially suitable for novice operators. With the help of LED projection lights to produce vertical projection, the positioning can be further accurate, achieving a "what you see is what you get" placement effect.

[0016] 2. Enhances the adhesion and stability of the clay blank; the annular groove can achieve: Physical anchoring: Wet mud is embedded in the grooves at the bottom of the clay block to form a mechanical interlock; Lateral resistance: During high-speed rotation, the annular groove provides lateral restraint, counteracting the sliding tendency caused by centrifugal force; Stress dispersion: The contact surface is divided into concentric circular areas to avoid local stress concentration and reduce bottom deformation; Water and air venting: Excess mud and water are guided and stored along the groove, and air bubbles are discharged through the escape path, reducing the risk of cracking during firing; Machining aids: Grooves can serve as a reference for diameter estimation and a cutting guide, improving operational convenience.

[0017] 3. Dynamic stability intelligent control: The centrifugal force of the rotating disk is monitored in real time by a piezoelectric force sensor, forming a closed-loop control with the electromagnet. When the centrifugal force exceeds the threshold, the electromagnetic attraction is automatically adjusted to counteract the longitudinal and transverse stresses, so that the rotating disk tends to be in dynamic balance. This design is especially suitable for eccentric or high-speed rotating conditions of the clay blank, which significantly improves the quality of ceramic production.

[0018] 4. Efficient switching between drawing and undrawing states; the combination design of elastic pads, connecting holes, and external pipes enables convenient switching between the two working states: During the throwing process: the elastic pad is recessed to maintain high adhesion and meet the requirements of anti-slip, water drainage, and air venting; Demolding state: The elastic pad bulges to parallel due to air inflation or magnetic repulsion, the bottom surface of the clay blank is smooth and flat, making it easy to demold, and the surface of the rotating disc returns to flatness, making it easy to clean.

[0019] 5. Low cost and easy maintenance; This invention adopts a modular design, and each component (such as electromagnet, elastic pad, LED projection lamp, etc.) is a common product on the market, which is low in cost, easy to replace and maintain. The outlet and annular groove design facilitates the collection and cleaning of mud and water, reducing the amount of maintenance work.

[0023] Please refer to the instruction manual appendix. Figure 1-11 The present invention provides a technical solution: a rotating base for ceramic manufacturing.

[0024] Example 1 refer to Figure 1 and Figure 2 As shown, the rotating base for ceramic production includes a first base 1 and a second base 2. The first base 1 is located above the second base 2. The first base 1 and the second base 2 together form a disc-shaped structure with an opening at the top. A rotating disk 3 is provided inside the first base 1. The surface of the rotating disk 3 is used to place the clay blank. When the rotating disk 3 rotates, it can drive the clay blank to rotate synchronously. The clay blank can be shaped by scraper or by hand to complete the shaping process of the clay blank.

[0025] During the shaping and throwing process, to ensure the stability of the clay blank, it needs to be accurately placed at the center of rotation. Beginners usually need extensive practice to master this skill, but errors still occur. Current techniques also employ tools to assist in centering, such as: Specialized equipment such as industrial-grade aluminum alloy packing turntables and rotating bases are used. These bases are made of sturdy and durable aluminum alloy and feature a double-bearing design, ensuring smooth and stable rotation, which helps in the stable placement and handling of clay blanks. However, they are costly. Therefore, this invention provides annular grooves 301 on the surface of the rotating disk 3. Multiple annular grooves 301 are concentrically distributed, and their diameters vary from small to large. Adjacent annular grooves 301 are painted with different colors of paint. When placing clay blanks, they can be positioned according to the outline of the annular grooves 301. For example, round clay blanks are easier to place at the center of the annular groove 301, i.e., the rotation center position. Furthermore, when the rotating disk 3 rotates the clay blanks, the annular grooves 301 enhance the adhesion of the clay blanks. First, the wet mud at the bottom of the clay blank is embedded in the grooves of the annular groove 301 to form a physical anchor. Second, when rotating at high speed, centrifugal force may cause the clay blank to slide or be thrown out, and the annular groove 301 provides lateral resistance. Third, the texture of the annular groove 301 divides the contact surface into concentric circular areas, disperses stress concentration, reduces bottom deformation, and improves the shaping quality of the clay blank. Fourth, excess mud and water during the throwing process can be guided and stored along the grooves of the annular groove 301, avoiding water accumulation at the bottom that could cause the clay blank to soften. It also provides an escape path for air bubbles between the clay blank and the rotating disk 3, preventing air bubbles from entering the clay blank and reducing the risk of bottom cracking during firing. Fifth, during the throwing process, the grooves of the annular groove 301 can be used as a reference for quickly estimating the diameter of the blank. When cutting the clay blank, the tool can slide along the grooves to ensure a smooth cut.

[0026] It should be noted that the annular groove 301 is machined by turning, with a depth controlled between 1-3mm (2mm in this invention) and a spacing of 5-15mm (10mm in this invention). It can be either V-shaped or U-shaped (V-shaped in this invention). Plaster powder or sponge can also be embedded in the annular groove 301 to prevent slipping and avoid the clay blank from sticking to the turntable.

[0027] In summary, the present invention, by providing annular grooves 301 on the surface of the rotating disk 3, takes into account the anti-slip properties of the clay blank, the cost and difficulty of centering, and the ease of cleaning the surface of the rotating disk 3.

[0028] refer to Figure 6 As shown, a drain outlet 101 is provided on one side of the first base 1. The mud and water that are separated during the throwing process will gradually enter the annular groove 102 at the bottom of the first base 1 and eventually be discharged through the drain outlet 101. A rubber plug is installed at the drain outlet 101. When it is opened, the mud and water stored in the first base 1 will be discharged without affecting the operation.

[0029] refer to Figures 3 to 6 As shown, a T-shaped drive shaft 4 is provided inside the second base 2. The T-shaped drive shaft 4 moves through the bottom of the second base 2. The upper end of the T-shaped drive shaft 4 is connected to the bottom of the rotating disk 3 by bolts. The lower end of the T-shaped drive shaft 4 is connected to the drive mechanism. When the drive mechanism drives the T-shaped drive shaft 4 to rotate, the rotating disk 3 rotates synchronously.

[0030] A first annular guide groove 302 and a second annular guide groove 303 are provided on the lower surface of the rotating disk 3. The first annular guide groove 302 is located in the inner circle of the second annular guide groove 303. The first annular guide groove 302 and the second annular guide groove 303 are arranged concentrically. The second base 2 is fixedly connected to the first base 1. A limiting protrusion 201 is provided at the upper end of the second base 2. The limiting protrusion 201 is slidably disposed in the second annular guide groove 303. A mounting base 5 is fixedly installed on the inner bottom surface of the second base 2. An electromagnet 6 is provided on the mounting base 5. The electromagnet 6 is slidably disposed in the first annular guide groove 302. When the electromagnet 6 is energized, it generates magnetism. The magnetism has a longitudinal and lateral attraction force on the rotating disk 3. When the rotating disk 3 rotates, the limiting protrusion 201 and the electromagnet 6 work together to guide and stabilize the rotating disk 3. Since the power of the electromagnet 6 is adjustable, the strength of the magnetism generated by the electromagnet 6 varies, and the degree of attraction to the rotating disk 3 varies. The rotating disk 3 can be targeted for stabilization according to the actual situation, such as: A piezoelectric force sensor 7 is installed at the bottom of the rotating disk 3. The piezoelectric force sensor 7 is used to monitor the centrifugal force of the rotating disk 3. The piezoelectric force sensor 7 is connected to the electromagnet 6 through a control chip. When the piezoelectric force sensor 7 detects that the centrifugal force of the rotating disk 3 is greater than the set threshold, the piezoelectric force sensor 7 feeds this data information back to the control chip. The control chip controls the magnitude of the current flowing through the electromagnet 6. If the centrifugal force is too large, the current flowing through it increases proportionally to counteract the longitudinal and lateral stresses of the rotating disk 3, thereby making the rotating disk 3 more stable when rotating. It is especially suitable for use in ceramic processes and can improve the quality of ceramic production.

[0031] Example 2 refer to Figure 7 As shown, the present invention also provides a device for use with a rotating base for ceramic manufacturing. The device includes a base plate 8 and a top plate 9. The base plate 8 is fixedly installed at the bottom of the second base 2. One side of the base plate 8 is connected to the top plate 9 via a bracket. The top plate 9 is located above the first base 1. A first slide rail 10 and an LED projection lamp 11 are installed below the top plate 9. A first slider 12 is slidably disposed in the first slide rail 10. A second slide rail 13 is fixedly installed at the bottom of the first slider 12. A second slider 14 is slidably disposed on the second slide rail 13. The sliding direction of the second slider 14 is perpendicular to the sliding direction of the first slider 12. A spring telescopic rod 15 is connected to the bottom of the second slider 14. A wristband 16 is fixedly connected to the bottom of the spring telescopic rod 15.

[0032] When placing the clay blank, turn on the LED projection light 11. First, put one hand through the wristband 16, then pick up the clay blank with both hands. Manually operate to move the first slider 12 directly above the first base 1. The second slider 14 adaptably slides on the second slide rail 13 until the clay blank is directly above the first base 1. Turn on the LED projection light 11, and the LED projection light 11 illuminates the clay blank to produce a vertical projection. The projection covers the annular groove 301 on the surface of the rotating disk 3 at the corresponding position. The annular groove 301 combined with the LED projection light 11 can clearly determine whether the position of the clay blank is at the center position of the rotating disk 3. When the clay blank is aligned with the center position of the rotating disk 3, move your hand vertically downward to place the clay blank at the exact center position of the rotating disk 3, which is convenient for quick centering.

[0033] It should be noted that there is a certain damping force between the first slider 12 and the first slide rail 10, and there is a certain damping force between the second slider 14 and the second slide rail 13. When the first slider 12 and the second slider 14 slide to the corresponding positions, they can be positioned. At this time, the vertical force of the hand is used to drive the hand ring 16 and the clay blank to descend, and the position is relatively accurate. The spring telescopic rod 15 can be a common spring telescopic rod on the market, which can extend and retract along the height direction of the rotating disk 3.

[0034] The drive mechanism that drives the rotating disk 3 to rotate includes a servo motor 17, which is fixedly mounted on the upper surface of the base plate 8. The upper shaft of the servo motor 17 is fixedly connected to the T-shaped transmission shaft 4.

[0035] As another implementation, the shaft on the servo motor 17 and the T-shaped transmission shaft 4 can also be connected by a magnetic coupler for transmission, which solves the problem of transmitting the positional vibration of the servo motor 17 to the rotating disk 3, making the rotating disk 3 rotate more stably.

[0036] Example 3 refer to Figures 8 to 10 As shown, an elastic pad 304 is fixedly installed at the upper opening of the annular groove 301. The elastic pad 304 is made of rubber material and has elastic deformation capability. A connecting hole 305 is also provided inside the rotating disk 3. Multiple annular grooves 301 are connected through the connecting hole 305. An outer pipe 306 is also installed on the outer periphery of the rotating disk 3. In the initial state, the elastic pad 304 is in a concave state to meet the stability of the clay blank adhering to the surface of the rotating disk 3. When it is necessary to remove the clay blank, an air pump is connected to the outer connecting pipe 306 using a quick-release head. Air is pumped into the annular groove 301, causing the elastic pad 304 to bulge upwards and become parallel to the upper surface of the rotating disk 3. After removing the air pump, the outer connecting pipe 306 is kept closed before rotating the rotating disk 3. This ensures the bottom of the clay blank remains smooth and flat, facilitating demolding. Furthermore, the surface of the rotating disk 3 returns to a flat state, making cleaning easier. This efficient switching between the two working states of throwing and demolding is achieved. During throwing, it maintains high adhesion, reduces air bubbles at the bottom of the clay blank, minimizes mud and water problems, and facilitates die cutting; During demolding, maintain low adhesion, ensure the bottom of the clay blank is smooth and flat without air bubbles, and restore the surface of the rotating disc 3 to a flat state, making it easy to clean.

[0037] Furthermore, during demolding, if air is continued to be injected into the annular groove 301, the elastic pad 304 will bulge slightly upwards, causing the bottom surface of the clay blank to separate from the upper surface of the rotating disk 3. This makes it less likely for the clay blank to stick during demolding, making demolding easier. Moreover, the elastic pad 304 will return to its original position after bulging slightly upwards, without causing deformation of the bottom surface of the clay blank. However, in actual use, if precise control is required, a pressure sensor needs to be integrated into the annular groove 301. The pressure sensor can be used to control the amount of air injected effectively, avoiding the problem of excessive bulging of the elastic pad 304 causing deformation of the bottom of the clay blank.

[0038] Example 4 refer to Figure 11 As shown, the elastic pad 304 can switch between a concave / parallel or bulging state. Another alternative method can also be used, such as: based on embodiment 3, a circular hole 307 is provided on the elastic pad 304, which penetrates the upper and lower surfaces of the elastic pad 304. An annular magnetic block 308 is also fixedly installed in the middle of the bottom of the elastic pad 304, and an electromagnet 309 is fixedly installed at the bottom of the annular groove 301. The electromagnet 309 corresponds to the annular magnetic block 308. When the electromagnet 309 is activated, it generates magnetism. The magnetic poles of the electromagnet 309 and the annular magnetic block 308 repel each other, causing the annular magnetic block 308 to drive the elastic pad 304 to bulge upward to a parallel state, thereby achieving the purpose of switching the state of the elastic pad 304 in another way. The operation is simple, and all products used are commonly available on the market, which is low in cost and easy to promote.

[0039] In Embodiment 4, an external pipe 306 can also be connected to a suction pump. When the suction pump is started, it can suck out the mud, water and air accumulated in the recess of the elastic pad 304, and then switch the elastic pad 304 to a parallel state, which effectively solves the destructive effect of mud, water or air inside the elastic pad 304 on the bottom surface of the clay blank.
