Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of forming equipment, and specifically relates to a rolling forming device for porcelain cups. Background Art
[0002] Drawing forming, slip casting forming, rolling forming, and manual plastic forming are all methods for forming ceramic cups. Among them, rolling forming has the characteristics of high production efficiency, good product quality, and relatively high green body strength compared to other ceramic cup forming methods, and is widely used.
[0003] Rolling forming is achieved by the relative movement of the rolling head of the forming device and the mold containing the clay material, applying pressure to the clay material, causing the clay material to gradually deform under the action of the pressure and conform to the shape of the mold, thereby forming the required ceramic green body. To accelerate the solidification and forming speed of the green body and facilitate demolding, existing molds are usually integrally formed with porous water-absorbing materials such as gypsum, acrylic resin, etc. However, during the rolling forming process, the mold needs to withstand the pressure of the rolling head on the mold and the friction force of the clay material. Existing molds are extremely prone to wear and cracking during use. To ensure the forming accuracy, once the mold wears beyond a certain range, it needs to be replaced, resulting in a short service life of the mold and high material costs.
[0004] For the forming of porcelain cups, the rolling head and the mold need to cooperate. In existing rolling forming equipment, both the rolling head and the mold are in a rotating state during operation. However, when the rolling head and the mold need to approach or separate due to operations such as feeding, the existing solutions usually involve either lifting the rolling head while keeping the mold stationary or keeping the rolling head stationary while lowering the mold, resulting in too long a movement stroke for the moving components, affecting the centering accuracy, and thus affecting the processing quality of porcelain cups.
[0005] In addition, after the porcelain cup is formed, it usually needs to be dried and demolded. The drying temperature should not be too high, and the temperature difference should not be too large, otherwise cracks are likely to occur. Therefore, the overall drying efficiency of the green body is currently relatively low. Summary of the Invention

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0021] 1. A composite mold is formed by the outer structural layer and the inner structural layer to achieve complementary performance. At least one end of the outer structural layer located at the open end of the inner structural layer is an open structure. When the inner structural layer is worn and cracked, the inner structural layer can be directly broken and taken out through the open end of the outer structural layer, and the inner structural layer is remolded on the inner wall of the outer structural layer. Therefore, only the inner structural layer needs to be replaced, reducing waste generation and lowering the material cost.
[0022] 2. Optimize the stress distribution during the use of the mold. When the mold is subjected to external forces or temperature changes, etc., the inner structural layer and the outer structural layer will restrict each other, making the stress distribution more uniform, thereby improving the bearing capacity and anti-deformation ability of the mold. The internal interface between the inner structural layer and the outer structural layer can hinder the expansion of fatigue cracks, thereby improving the anti-fatigue performance of the mold and prolonging the service life of the mold.
[0023] 3. The composite die is placed inside the lifting sleeve. The second shoulder contacts the inner wall surface of the top of the lifting sleeve, and the first shoulder contacts the top wall of the lifting sleeve, realizing a stable coaxial sleeve of the composite die and the lifting sleeve. The composite die is placed in the die hole along with the lifting sleeve. When the first cam rotates, it can drive the connecting plate to move up and down through the lifting wheel. When the lifting shaft rises, the boss cooperates with the notch, so as to drive the die to rotate through the lifting shaft. When the second cam rotates, it can drive the swing arm to rotate around the horizontal axis through the roller, making the rolling head move up and down. The fourth motor can drive the rolling head to rotate. The composite die and the rolling head of this device can move closer to or away from each other. The centering accuracy of the composite die and the rolling head is high. When the lifting shaft rises, it can cooperate with the lifting sleeve to drive the composite die to rotate. When the lifting shaft descends, it can disengage from the lifting sleeve. The lifting sleeve rotates with the rotating platform and enters the drying process. The lifting shaft can drive the next lifting sleeve to roll and form the clay material in the composite die, improving the production efficiency.
[0024] 4. Hot air is sent into the rotating platform through the air inlet pipe. The hot air diffuses and blows towards the porcelain cup blank in the composite die through the air holes, reducing the wind pressure directly blowing on the porcelain cup blank. The hot air blowing through the air holes towards the lower part of the middle partition enters the exhaust cavity through the gap between the support plate and the outer plate. The hot air in the exhaust cavity can further heat the composite die, avoiding too large temperature difference, improving the utilization of waste heat and saving energy consumption.

[0041] Techniques, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and devices should be regarded as part of the specification.
[0042] Please refer to Figures 1 - 9As shown in the figure, this embodiment provides a porcelain cup rolling forming device, which includes a mounting base 1, a rotating lifting device 2, a rolling device 3, a rotating platform 4, and a composite mold 9. There is a mounting base 1 on one side of the rotating platform 4. The mounting base 1 is provided with a rolling device 3 and a rotating lifting device 2. The composite mold 9 is installed on the rotating platform 4;
[0043] The composite mold 9 includes an outer structure layer 91 and an inner structure layer 92 that are coaxially sleeved. At least one end of the outer structure layer 91 is an open structure. One end of the inner structure layer 92 is closed, and the other end is an open structure. A mold cavity 98 is formed inside the open end of the inner structure layer 92. The strength of the outer structure layer 91 is higher than that of the inner structure layer 92.
[0044] The outer structure layer 91 with higher strength is coated on the outside of the inner structure layer 92. Compared with a single-material mold under the same working conditions, the wall thickness of the inner structure layer 92 and even the entire mold can be reduced. The outer structure layer 91 is usually not damaged and can be recycled. Only the inner structure layer 92 is damaged. At least one end of the outer structure layer 91 located at the open end of the inner structure layer 92 is an open structure. When the inner structure layer 92 wears and cracks, the inner structure layer 92 can be directly broken and taken out through the open end of the outer structure layer 91, and the inner structure layer 92 is remolded on the inner wall of the outer structure layer 91. Therefore, only the inner structure layer needs to be replaced, reducing waste generation and lowering material costs.
[0045] It also optimizes the stress distribution during the use of the composite mold 9. When the composite mold 9 is subjected to external forces or temperature changes, etc., the inner structure layer 92 and the outer structure layer 91 will restrict each other, making the stress distribution more uniform, thereby improving the bearing capacity and anti-deformation ability of the composite mold. The internal interface between the inner structure layer 92 and the outer structure layer 91 can hinder the propagation of fatigue cracks, thereby improving the anti-fatigue performance of the mold and extending the service life of the composite mold 9.
[0046] Preferably, the outer structure layer 91 can adopt an open structure at both ends, which is convenient for breaking and taking out the failed inner structure layer 92, and avoiding the inner structure layer 92 remaining in the outer structure layer 91 and affecting the casting quality of the new inner structure layer 92.
[0047] Preferably, the outer structure layer 91 is made of a metal material, and the inner structure layer 92 is made of a water-absorbing and breathable material.
[0048] Specifically, the outer structure layer 91 is made of stainless steel. The material of the inner structure layer 92 is one or two of gypsum and acrylic resin.
[0049] It should be noted that the outer structural layer 91 is not limited to a single-layer structure, and the outer structural layer 91 itself can also be a multi-layer structure. The inner structural layer 92 is not limited to a single-layer structure, and the inner structural layer 92 itself can also be a multi-layer structure. Preferably, a buffer layer can be provided inside the outer structural layer 91 and / or inside the inner structural layer 92 and / or between the outer structural layer 91 and the inner structural layer 92.
[0050] It should be noted that to ensure the structural strength of the composite mold 9, both ends of the outer structural layer 91 and the inner structural layer 92 are flush, avoiding the formation of weak strength points and affecting the service life of the composite mold 9.
[0051] In some embodiments, please refer to Figure 9 , a step 97 is provided on the inner wall of the closed end of the outer structural layer 91 where the outer structural layer 91 is located inside the inner structural layer 92. The step 97 protrudes from the inner wall of the outer structural layer 91, and a first groove corresponding to the step 97 is provided on the outer wall of the closed end of the inner structural layer 92. Since both ends of the outer structural layer 91 are open ends, the cooperation of the step 97 and the first groove can prevent the axial slip between the outer structural layer 91 and the inner structural layer 92.
[0052] In some embodiments, please refer to Figures 7 - 9 As shown, a second groove is provided on the side wall of the outer structural layer 91, and a stacked first shoulder 93 and a second shoulder 94 are embedded in the second groove. The first shoulder 93 and the second shoulder 94 are both coaxially installed with the outer structural layer 91. The first shoulder 93 and the second shoulder 94 are embedded in the side wall of the outer structural layer 91, which can enhance the strength of the first shoulder 93 and the second shoulder 94, reduce stress concentration, and prevent the deformation of the first shoulder 93 and the second shoulder 94.
[0053] Preferably, the second shoulder 94 is located on the side of the first shoulder 93 away from the open end of the inner structural layer 92, and the outer diameter of the first shoulder 93 is greater than the outer diameter of the second shoulder 94.
[0054] Furthermore, a third shoulder 95 is formed on the side wall of the outer structural layer 91. The third shoulder 95 is located on the side of the second groove away from the open end of the inner structural layer 92. The third shoulder 95 is in the shape of a frustum of a cone, and the larger end of the third shoulder 95 abuts against the second shoulder 94.
[0055] In some embodiments, please refer to Figure 2 , Figure 3 As shown, a bottom pad 96 is provided at the closed end of the inner structural layer 92 where the mold cavity 98 is located, facilitating the formation of the shape of the cup bottom. Preferably, the outer peripheral surface of the bottom pad 96 is an arc surface, facilitating demolding.
[0056] In some embodiments, the first shoulder 93 and the second shoulder 94 can be integrally formed with the outer structural layer 91, facilitating processing.
[0057] It should be noted that: the first vest 93, the second vest 94, and the outer structural layer 91 can all be recycled. Place the outer structural layer 91 upside down on the platform, with the first vest 93 and the second vest 94 at the lower end. Place a mold with the same shape as the ceramic cup coaxially inside the outer structural layer 91, with the cup mouth of the mold with the same shape as the ceramic cup placed on the platform. Pour the inner structural layer 92 into the outer structural layer 91. After drying and hardening, take out the mold with the same shape as the ceramic cup, and the production of the composite mold is completed. The production is simple, greatly reducing the material input of the inner structural layer 92, saving the mold cost, reducing the generation of waste, and reducing the impact on the environment.
[0058] In some embodiments, refer to Figure 3 , Figure 4 As shown, the rotary lifting device 2 includes a first motor 21, a second motor 23, a lifting shaft 26, a transmission shaft 28, a connecting plate 210, a lifting wheel 211, a support shaft 212, a first cam 213, a lifting sleeve 215, and a slide rail 216.

A support seat 22 is installed on the mounting seat 1 to support the output shaft of the first motor 21. The output shaft of the first motor 21 passes through the side plate of the mounting seat 1 and is connected to the first cam 213. The first cam 213 can rotate under the drive of the first motor 21. A pair of slide rails 216 are provided on one side of the mounting seat 1 close to the rotary platform 4. A connecting plate 210 is assembled on the slide rails 216. A support shaft 212 is provided on one side of the connecting plate 210. A lifting wheel 211 is sleeved at the end of the support shaft 212. The lifting wheel 211 contacts the first cam 213. A second motor 23 and a sleeve seat 29 are provided on the other side of the connecting plate 210. An outer sleeve is sleeved outside the lifting shaft 26. The outer sleeve is installed on the connecting plate 210 through the sleeve seat 29. The end of the drive shaft of the second motor 23 is installed with a first pulley 24. A second pulley 25 is installed at the lower end of the transmission shaft 28. The first pulley 24 and the second pulley 25 are connected by a belt. The lifting shaft 26 is fixedly sleeved on the transmission shaft 28. A boss 261 is provided at the top of the lifting shaft 26. A notch matching the boss 261 is provided at the bottom of the lifting sleeve 215.
[0059] Preferably, the outer sleeve includes a top sleeve 27 and a bottom sleeve 214. The top sleeve 27 and the bottom sleeve 214 are respectively sleeved at both ends of the lifting shaft 26, which can reduce the weight and the rotational resistance of the lifting shaft 26. To further reduce the frictional resistance of the rotation of the lifting shaft 26, bearings can be installed between the top sleeve 27 and the lifting shaft 26, and between the bottom sleeve 214 and the lifting shaft 26.
[0060] The composite die 9 is placed inside the jacking sleeve 215. The second shoulder 94 contacts the inner wall surface of the top of the jacking sleeve 215, and the first shoulder 93 contacts the top wall of the jacking sleeve 215, realizing the stable coaxial sleeving of the composite die 9 and the jacking sleeve 215. The composite die 9 is placed in the die hole 451 together with the jacking sleeve 215. By rotating the first cam 213, the lifting wheel 211 can be driven to move up and down, so that the jacking shaft 26 and the second motor 23 installed on the connecting plate 210 move up and down. When the jacking shaft 26 rises, the boss 261 cooperates with the notch, and the composite die 9 leaves the die hole 451 together with the jacking sleeve 215. The drive shaft of the second motor 23 rotates, driving the first pulley 24 to rotate, and transmitting the rotational motion to the second pulley 25 through the belt. The second pulley 25 drives the jacking shaft 26 to rotate together, and the jacking shaft 26 drives the jacking sleeve 215 to rotate together, so as to drive the composite die 9 to rotate through the jacking shaft 26. When the jacking shaft 26 descends, the composite die 9 returns to the die hole 451 together with the jacking sleeve 215, and the boss 261 is separated from the notch. The composite die 9 is statically placed in the die hole 451 together with the jacking sleeve 215, waiting to enter the drying process. The composite die 9 in the next die hole 451 starts to feed and form a blank.

The worm gear box 34 is arranged on the mounting seat 1. A worm box 35 is fitted on the worm gear box 34. A third motor 31 is also installed on the mounting seat 1. A third pulley 32 is installed at the end of the drive shaft of the third motor 31. The worm in the worm box 35 extends out of the worm box 35 and is installed with a fourth pulley 33. The third pulley 32 and the fourth pulley 33 are connected by a belt. When the output shaft of the third motor 31 rotates, it drives the third pulley 32 to rotate together, and transmits the rotation to the fourth pulley 33 through the belt. The fourth pulley 33 drives the worm to rotate. A worm gear shaft 36 is assembled with the worm gear in the worm gear box 34. A second cam 37 is installed on the worm gear shaft 36. A pair of supports 310 are also provided on the mounting seat 1. A cross shaft 311 is erected between the two supports 310. A swing arm 39 is arranged on the cross shaft 311. A roller 38 is installed on the swing arm 39. The roller 38 contacts the second cam 37. When the worm rotates, it drives the worm gear shaft 36 to rotate through the worm gear. The second cam 37 rotates following the worm gear shaft 36, causing the roller 38 to move up and down, so that the swing arm 39 rotates around the cross shaft 311. One end of the swing arm 39 close to the rotary table 4 is provided with a rolling head seat 312. The bottom of the rolling head seat 312 is installed with a rolling head 314 through a rotating shaft 313.

[0063] In this device, the composite die 9 and the rolling head 314 can move closer to or away from each other. The centering accuracy of the composite die 9 and the rolling head 314 is high. When the lifting shaft 26 rises, it can cooperate with the lifting sleeve 215 to drive the composite die 9 to rotate. When the lifting shaft 26 descends, it can disengage from the lifting sleeve 215. The lifting sleeve 215 rotates with the rotary table 4 and enters the drying process. The lifting shaft 26 can drive the next lifting sleeve 215 to roll and form the mud in the composite die 9, improving the production efficiency.

The specific structure of the conveying device is not described in detail here. Figures 1 - 3Only the conveyor belt 319 is shown, and other structural parts of the conveying device are not shown. For details, refer to the prior art.
[0068] In some embodiments, refer to Figure 5 , Figure 6 As shown, the rotary platform 4 includes an outer cover 41, a middle partition plate 44, a support plate 45, a bench 47 and a turntable driving device 48. The turntable driving device 48 is arranged on the top of the bench 47. A support plate 45 is arranged on the turntable driving device 48. Mold holes 451 are circumferentially and uniformly arranged on the support plate 45. A fixing plate 410 is further installed on the top of the bench 47. The outer cover 41 is fixedly installed on the fixing plate 410. A middle partition plate 44 is installed inside the outer cover 41. The middle partition plate 44 is located above the support plate 45. Air holes 49 are circumferentially and uniformly arranged on the middle partition plate 44. The internal space of the outer cover 42 is sequentially divided into an air inlet chamber, a drying chamber and an air exhaust chamber from top to bottom by the middle partition plate 44 and the support plate 45. An air inlet pipe 5 communicating with the air inlet chamber and an air outlet pipe 6 communicating with the air exhaust chamber are arranged on the outer cover 41.
[0069] Preferably, the turntable driving device 48 is arranged on the top of the bench 47. A mounting plate 46 is arranged on the turntable driving device 48. The support plate 45 is arranged on the outer periphery of the mounting plate 46. Mold holes 451 are circumferentially and uniformly arranged on the support plate 45. A fixing plate 410 is installed on the top of the bench 47. The fixing plate 410 is located above the mounting plate 46. An inner side plate 43 is fixedly installed on the fixing plate 410. The outer cover 41 is installed on the inner side plate 43. An outer side plate 42 is installed on the inner wall of the outer cover 41. The middle partition plate 44 is arranged on the side of the outer side plate 42 close to the inner side plate 43. The middle partition plate 44 is located above the support plate 45. Air holes 49 are circumferentially and uniformly arranged on the middle partition plate 44. An air inlet chamber is formed between the outer cover 42 and the middle partition plate 44. A drying chamber is formed between the middle partition plate 44 and the support plate 45. An air inlet pipe 5 communicating with the air inlet chamber is arranged on the outer cover 42. A cross plate is arranged at the bottom of the inner side wall of the outer side plate 42. A vertical plate is further arranged on the cross plate. The vertical plate, the cross plate, the outer side plate 42 and the support plate 45 enclose an air exhaust chamber. The cross plate is connected with an air outlet pipe 6 communicating with the air exhaust chamber.
[0070] The turntable driving device 48 can drive the mounting plate 46 and the support plate 45 to rotate together. The air inlet duct 5 is connected to a hot air device, and the air outlet duct 6 is connected to an induced draft fan 7. The air outlet of the induced draft fan 7 is connected to the hot air device through a duct. The longitudinal section of the middle partition plate 44 is in an "L" shape, and the air holes 49 are located on the transverse plate. During the rotation of the support plate 45, each composite mold 9 will successively pass directly below each air hole 49. The height of the longitudinal plate is lower than the heights of the outer plate 42 and the inner plate 43. Hot air is sent into the air inlet cavity through the air inlet duct 5. The hot air diffuses while blowing through the air holes 49 towards the porcelain cup blanks in the composite mold 9, reducing the wind pressure directly blowing on the porcelain cup blanks. The hot air blowing through the air holes 49 into the drying cavity, as well as the hot air diffusing into the drying cavity through the gap between the outer cover 41 and the longitudinal plate of the middle partition plate 44, further enters the exhaust cavity through the gap between the support plate 45 and the outer plate 42.

The air in the exhaust cavity is extracted through the air outlet duct 6 under the action of the induced draft fan 7 and sent back to the hot air device for reheating. The hot air device is a prior art for generating drying hot air and will not be elaborated here.
[0071] The rotary platform 4 is provided with a blank making opening and a blank taking opening. The mounting seat 1 is located beside the blank making opening. A blank feeding device is also provided beside the blank making opening for feeding an appropriate amount of porcelain clay into each composite mold 9. The blank taking opening is provided with a blank taking device for taking out the dried porcelain cup blanks. The blank feeding device and the blank taking device are both selected from the prior art.
[0072] Further, the turntable driving device 48 drives the mounting plate 46 and the support plate 45 to rotate clockwise. A drying and shaping section and an empty mold section are formed between the blank making opening and the blank taking opening. The air inlet duct 5 and the air outlet duct 6 are arranged in the drying and shaping section. During the process that the support plate 45 drives the formed porcelain cup blanks to rotate to the blank taking opening through the drying and shaping section, the blanks are dried and shaped to prevent damage to the blanks during the blank taking process by the blank taking device. After the porcelain cup blanks are taken out, the composite mold 9 reaches the blank making opening again through the empty mold section for blank making with the fed material.
[0073] Preferably, the outer surface of the outer cover 41 of the drying and shaping section is covered with a heat insulation cover to reduce heat loss and prevent scalding accidents.
[0074] In some embodiments, please refer to Figure 1 、 Figure 2 As shown, it further includes a bottom plate 8. The mounting seat 1 and the rotary platform 4 are both mounted on the bottom plate 8.

[0077] Porcelain cup forming process:
[0078] The composite mold 9 is correctly installed in the jacking sleeve 215. In each mold hole 451, the composite mold 9 is placed well through the jacking sleeve 215. The feeding device feeds an appropriate amount of porcelain clay into the composite mold 9 that is about to move under the rolling head 314. The rotary jacking device 2 jacks out the jacking sleeve 215 from the mold hole 451 and drives the jacking sleeve 215 to rotate with the composite mold 9. At the same time, under the action of the swing arm 39, the rolling head 314 moves towards the composite mold 9 and enters the mold cavity 98 in a rotating manner to "roll" and "press" the porcelain clay. Under the action of centrifugal force and pressure, the porcelain clay is extruded and formed, gradually fitting the shape of the mold, forming a blank of the ceramic cup, realizing the rolling forming of the ceramic cup. Subsequently, the rotary jacking device 2 drives the composite mold 9 to descend and fall back into the mold hole 451. The rotary platform 4 rotates, and the next composite mold 9 is fed and sent under the rolling head 314. The rotation of the composite mold 9 can make the relative movement between the rolling head 314 and the composite mold 9 more adaptable, so as to ensure the uniform distribution of the porcelain clay in the composite mold 9, which helps to form a ceramic blank with uniform wall thickness and regular shape. In addition, the rotation of the composite mold 9 can also make the pressure applied by the rolling head 314 on the porcelain clay more stable and uniform, making the density of the blank higher and improving the product quality.
[0079] The formed porcelain cup blank is sent into the drying and shaping section of the outer cover 41 with the composite mold 9 for drying until it rotates to the blank taking port. The blank taking device takes out the porcelain cup blank in the composite mold 9. After the porcelain cup blank is taken out, the composite mold 9 rotates with the support plate 45 and enters the empty mold section of the outer cover 41, and then goes to the blank making port again for blank making and feeding.
