Description

Technical Field

[0001] This invention relates to the field of soft porcelain processing technology, and in particular to a processing method and apparatus for three-dimensional relief soft porcelain. Background Technology

[0002] With the development of modern building decoration technology, people have put forward higher and more comprehensive demands for decoration effects. On some curved or irregular exterior wall surfaces, it is difficult to completely cover the surface when using traditional ceramic tiles. As a result, flexible ceramic products have emerged. Flexible ceramic was originally made by modifying clay and baking it at a low temperature to create a decorative sheet material with a similar decorative effect to ceramic tiles. Because it has a certain degree of flexibility and can be shaped according to the object, it was named "flexible ceramic".

[0003] Currently, most flexible ceramic tiles use stone powder and calcium powder as aggregates, and cement and water-based resin (emulsion) as binders. They are formed through low-temperature curing, allowing them to fully express the textures of natural marble, wood, and leather. They are used to replace traditional decorative materials such as ceramic tiles, stone paint, and coatings. The key difference between flexible ceramic tiles and traditional ceramic tiles lies in their texture. Flexible ceramic tiles are soft, with prominent patterns and a strong three-dimensional effect. They are flexible and not easily broken, making them a low-carbon, environmentally friendly, and lightweight building decoration material. Due to their lightweight, flexibility, diverse shapes, and good weather resistance, they are increasingly used in high-rise buildings, interior decoration, large public entertainment venues, public transportation facilities, and many other fields.

[0004] With the development of flexible porcelain, its varieties have become increasingly diverse. For example, relief carving is combined with flexible porcelain to create three-dimensional relief patterns on the surface, which are then printed and colored to produce artistic flexible porcelain materials with superior visual effects. Considering the flexibility of flexible porcelain, the current processing method usually involves baking the flexible porcelain to a certain degree of plasticity, then pressing it onto the surface with an external mold to create a relief shape, followed by a second baking to set the final product. However, this approach has significant problems. First, it requires breaking up the baking process and performing molding operations in between, leading to discontinuous production lines and reduced production efficiency. Second, during molding, considering the viscosity of the flexible porcelain material and the large contact area between the mold and the porcelain, coupled with the relatively small surface area of ​​the porcelain itself, adhesion problems easily occur during demolding, causing damage to the relief shape on the surface of the flexible porcelain. Therefore, a more suitable processing method is needed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a processing method and apparatus for three-dimensional relief soft porcelain, which solves the problems of low production efficiency, easy damage to relief patterns, and low yield rate in existing technologies.

[0006] In a first aspect, the present invention proposes a three-dimensional relief soft porcelain processing device, including a horizontally arranged conveying mechanism and a base plate placed on the conveying mechanism for transportation. The conveying mechanism is provided with a feeding mechanism and a baking mechanism in sequence along the transportation direction. It also includes an auxiliary mechanism that works in conjunction with the base plate to separate the two without damaging the base plate and the soft porcelain.

[0007] The base plate includes a central part with an embossed concave mold and a detached part surrounding the outer edge of the central part. The width of the detached part is much smaller than the size of the central part. The upper surface of the detached part is provided with a number of channels. The channels are perpendicular to the corresponding edges of the base plate and connect the central part with the external space.

[0008] Furthermore, the channel has an inclined structure, with one end corresponding to the center being higher and the other end corresponding to the external space being lower.

[0009] Furthermore, it also includes a clamping head that is designed to fit the channel. The clamping head is a pointed structure that corresponds to the inclined shape of the channel. The bottom of the clamping head is inclined and closely attached to the bottom surface of the channel, while the top is horizontally attached to the upper surface of the base plate. The end of the clamping head away from the center extends to the outside of the channel.

[0010] Furthermore, the auxiliary mechanism includes a fan and a connector. The connector and the fan are connected by a flexible hose. One end of the connector is connected to the flexible hose, and the other end is a horizontal contact surface. The connector has an air duct perpendicular to the contact surface, and an air outlet is correspondingly provided on the contact surface. One end of the air duct is connected to the air outlet, and the other end passes through the connector and is connected to the flexible hose.

[0011] Furthermore, an adhesive layer is provided on the contact surface. The adhesive layer has an upper layer and a lower layer that are distributed adjacent to each other. The width of the upper layer corresponds to the thickness of the soft ceramic and is made of a flexible material. The width of the lower layer corresponds to the thickness of the base plate and is made of a smooth, hard material.

[0012] Furthermore, the connector is also provided with a clamping component, which includes clamping pieces symmetrically arranged on the upper and lower sides of the connector perpendicular to the contact surface. The clamping pieces are sheet-like structures that protrude in the middle toward the connector and extend away from the connector at both ends. The protruding part in the middle is hinged to the connector and is provided with a torsion spring. One end of the clamping piece near the contact surface extends out of the connector and is fitted with a clamping plate. The clamping plate can be rotated to a state where it is parallel to and attached to the outer side of the base plate or the soft ceramic.

[0013] Secondly, the present invention also proposes a method for processing three-dimensional relief soft porcelain, comprising the following steps:

[0014] S1. Base plate making: Carve on the surface of a solid sheet to create a relief mold. Cover the surface of the mold with thermoplastic silicone, then heat it to the melting point of the thermoplastic silicone to melt it into a fluid and completely adhere it to the surface of the mold. After stabilization, allow it to cool naturally, then peel off the reshaped thermoplastic silicone to obtain a base plate with a relief mold.

[0015] S2. Raw material mixing: Take the corresponding raw materials according to the following proportions by weight: 10-30 parts of supercalcium, 50-75 parts of quartz sand, and 5-20 parts of water-based resin. Place them in a mixer and add 10%-30% of the total weight of the raw materials while stirring until the raw materials are fully dissolved and gelled, so that the viscosity reaches 2000-2800 Pa·s.

[0016] S3. Baking and shaping: The raw material prepared in step S2 is injected into the base plate prepared in step S1, and the top surface of the raw material is smoothed and the thickness is uniform. Then, it is sent into the baking mechanism through the conveying mechanism and baked at 80°C for 2 to 6 hours. After baking, it is taken out and placed to cool naturally to obtain a combination of hardened soft porcelain and base plate.

[0017] S4. Soft porcelain demolding: Use an auxiliary mechanism to separate the soft porcelain from the base plate, so as not to damage the soft porcelain and the raised or recessed relief structure on the base plate.

[0018] S5. Printing and Coloring: Use a printer to print and color the relief on the surface of the soft porcelain, thereby producing a three-dimensional relief soft porcelain product.

[0019] Preferably, in step S2, the waterborne resin is one or a mixture of acrylic resin, waterborne polyurethane, and waterborne epoxy resin.

[0020] Preferably, in step S2, the heavy calcium carbonate is processed into 400-mesh powder, and 80-120 mesh quartz sand powder is screened as raw material.

[0021] Furthermore, in step S3, a release agent is first sprayed onto the surface of the base plate before the raw material prepared in step S2 is injected.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. This invention directly processes the base plate used for soft porcelain production into a concave mold, thereby forming the soft porcelain in one step during the process of soft porcelain raw material injection and baking, completing the surface relief processing of soft porcelain. There is no need to divide the baking process into two parts, thus completing the production of soft porcelain in one step through a single production line, improving production efficiency.

[0024] 2. This invention uses a base plate as a concave mold to produce soft porcelain, eliminating the need for mold pressing. The base plate itself is made of flexible silicone, which has deformability and extensibility, making it easier to separate from the soft porcelain. Since there is no pressing process, the two are not too tightly bonded, thus reducing the difficulty of separating the base material from the soft porcelain. Consequently, it also reduces the probability of damage to the surface of the soft porcelain during the separation process, thereby improving product quality.

[0025] 3. In the production of flexible porcelain, the substrate and flexible porcelain are inevitably bonded together as a whole after simultaneous sintering, although the tightness of the bond may differ. Traditionally, a hard substrate, after sintering, is bonded to the hard flexible porcelain, and separation can only be achieved by fixing one and then lifting the other vertically. This inevitably damages the relief pattern. This invention, however, uses a soft, flexible substrate that can be bent and rolled up. Therefore, the original "lifting" separation method is transformed into a "lifting" separation method from the side. Clearly, the method of separating the flexible porcelain and substrate simultaneously from the entire connecting surface is changed to rolling and lifting the substrate from the edge of the connecting surface between the flexible porcelain and the substrate. Essentially, this transforms surface contact into line contact, significantly reducing the contact area of ​​the separation tension during the separation process and avoiding separation damage caused by differences in localized bonding forces between the substrate and the flexible porcelain.

[0026] In the aforementioned "lifting" separation method, the bonding surface between the soft porcelain and the substrate in the edge area is relatively tight after sintering, making it difficult to find the separation point. Therefore, this invention provides a channel structure, thereby artificially creating a "gap" to facilitate starting the rolling and separation of the substrate from the channel. This further reduces the difficulty of separating the substrate and the soft porcelain, and avoids damage to the edges of the soft porcelain or substrate when separation begins at the edge bonding surface.

[0027] 4. This invention also provides an auxiliary mechanism to separate the base plate and the flexible ceramic without damaging them. The auxiliary mechanism includes a fan and a connector. A corresponding channel is provided on the base plate. The connector can be used to approach the edge of the base plate and the flexible ceramic assembly at the location of the channel. The fan blows air into the channel, using the airflow to separate the flexible ceramic from the base plate. The auxiliary mechanism works in conjunction with the channel. Considering that the actual size of the channel is relatively small compared to the side of the base plate, the gap created by the channel alone is insufficient to easily lift the base plate from the entire side. Therefore, the auxiliary mechanism blows air inward to widen the gap created by the channel, making it easier to lift the base plate and further reducing the possibility of damaging the relief pattern during demolding.

[0035] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0036] like Figure 1 As shown in the figure, the present invention provides a three-dimensional relief soft porcelain processing device, including a horizontally arranged conveying mechanism 1 and a base plate 4 placed on the conveying mechanism 1 for transportation. The conveying mechanism 1 is provided with a feeding mechanism 2 and a baking mechanism 3 in sequence along the transportation direction. It also includes an auxiliary mechanism that works in conjunction with the base plate 4 to separate the base plate 4 and the soft porcelain without damaging them.

[0037] In this specific embodiment, the conveying mechanism 1 uses a roller conveyor belt or a chain conveyor belt to prevent it from being affected by high temperatures when passing through the baking mechanism 3. This embodiment preferably uses a chain conveyor belt, which offers a more stable and continuous transport process. It should be noted that baffles of the same width as the base plate 4 are provided on both sides of the chain conveyor belt. These baffles move simultaneously with the chain conveyor belt, sealing the sides of the base plate 4 to prevent slurry from flowing out of the conveying mechanism 1 and causing pollution to the factory floor. The feeding mechanism 2 is equipped with a liquid injection pump and a leveling brush to inject slurry onto the base plate 4 and level it. Since this is prior art, it will not be described in detail here.

[0038] like Figure 2As shown, further, the base plate 4 includes a central portion 41 with an embossed mold and a release portion 42 surrounding the outer edge of the central portion 41. The width of the release portion 42 is much smaller than the size of the central portion 41. The upper surface of the release portion 42 is provided with a plurality of channels 43. The channels 43 are perpendicular to the corresponding edges of the base plate 4 and connect the central portion 41 with the external space. That is, the square central portion 41 is provided with an embossed mold, and a ring of square release portions 42 surrounds it, with the width of the release portions 42 being uniform.

[0039] like Figure 3 As shown, preferably, the channel 43 has an inclined structure, with one end corresponding to the center 41 positioned higher and the other end corresponding to the external space positioned lower. Furthermore, it also includes a locking head 5 that mates with the channel 43. The locking head 5 is a pointed structure corresponding to the inclined shape of the channel 43. The bottom of the locking head 5 is inclined and closely adheres to the bottom surface of the channel 43, while the top is horizontally attached to the upper surface of the base plate 4. The end of the locking head 5 away from the center 41 extends to the outside of the channel 43. When the locking head 5 is inserted into the channel 43, its inclined bottom surface makes close contact with the inclined surface of the channel 43, thereby sealing the channel 43. At the same time, the top surface of the locking head 5 is flush with the upper surface of the detachment portion 42 of the base plate 4, forming a complete plane that does not affect the normal processing of the soft porcelain. Therefore, after the flexible porcelain has been baked and processed, the clip 5 can be pulled out. At this point, only the top of the clip 5 contacts the flexible porcelain, while the bottom contacts the groove 43 via the inclined surface. Only a slight pulling force is needed to separate the clip 5 from the inclined surface of the groove 43, thus avoiding frictional force exerted on the clip 5 by the base plate 4, making it easy to pull out the clip 5. The clip 5 can also move downwards to disengage from the flexible porcelain without rubbing against the bottom surface of the flexible porcelain during outward pulling, preventing wear and tear on the surface of the flexible porcelain. After the clip 5 is pulled out, a separation point appears between the flexible porcelain and the base plate 4. The flexible base plate 4 can be peeled off gradually through this separation point, which is more convenient and less likely to damage the relief pattern on the flexible porcelain.

[0040] like Figure 4 As shown, in a further embodiment, the auxiliary mechanism includes a fan 6 and a connector 8. The connector 8 is connected to the fan 6 via a flexible hose 7. One end of the connector 8 is connected to the flexible hose 7, and the opposite end is a horizontal contact surface. An air duct perpendicular to the contact surface is provided inside the connector 8, and an air outlet 81 is correspondingly provided on the contact surface. One end of the air duct is connected to the air outlet 81, and the other end passes through the connector 8 and connects to the flexible hose 7. The fan 6 can be a regular blower 6 or a high-pressure blower 6, thus outputting airflow through the connector 8. When the connector 8 abuts against the surface of the channel 43 through the contact surface and is aligned with the channel 43 through the air outlet 81, airflow can be forced through the channel 43 between the flexible ceramic and the base plate 4, further loosening the contact surface between the flexible ceramic and the base plate 4, achieving a better separation effect.

[0041] like Figure 5 As shown, in this embodiment, an attachment layer 9 is also provided on the contact surface. The attachment layer 9 has an upper layer 91 and a lower layer 92 distributed adjacent to each other. The width of the upper layer 91 corresponds to the thickness of the soft ceramic and is made of flexible silicone material. The width of the lower layer 92 corresponds to the thickness of the base plate 4 and is made of a smooth, hard material, which is PVC plastic in this embodiment. Because the soft ceramic is harder than the flexible silicone base plate 4 after baking, the flexible silicone upper layer 91 is used to contact it. The base plate 4 is softer, so a hard, smooth PVC plastic is used to contact it. That is, after the upper layer 91 and the lower layer 92 come into contact with the soft ceramic and the base plate 4, they achieve mutual interlocking and deformation through the contact of the hard and soft surfaces, resulting in a tighter contact and better sealing, making it less likely for wind to leak out. It should be noted that in this embodiment, it is not necessary to achieve a complete seal between the connector 8 and the base plate 4 and the side of the soft porcelain. It is only necessary to ensure that a certain amount of wind can enter the gap between the base plate 4 and the soft porcelain through the channel 43, thereby reducing the tightness of the connection between the base plate 4 and the soft porcelain to a certain extent.

[0042] like Figure 6 As shown, preferably, the connector 8 is further provided with a clamping member, which includes clamping pieces symmetrically arranged on the upper and lower sides of the connector 8 perpendicular to the contact surface. Each clamping piece is a sheet-like structure that protrudes towards the connector in the middle and extends away from the connector 8 at both ends. Each clamping piece includes a connecting section 82 extending towards the contact surface, a pressing section 83 extending towards the hose 7, and a rotating shaft 84 protruding between the two. The rotating shaft 84 is hinged to the surface of the connector 8 and is equipped with a torsion spring (not shown). The connecting section 82 extends to the outside of the contact surface and is fixedly mounted with a clamping plate 85. The clamping plate 85 can rotate to a state where it is parallel to and attached to the outer surface of the base plate 4 or the soft ceramic. The clamping member has a structure similar to a clip used in daily life, with its two ends corresponding to the two ends of the connector 8 connected to the contact surface and the hose 7, respectively, so that the clamping plate 85 extends beyond the contact surface. Simultaneously, the torsion spring controls the clamping pieces to rotate towards the connecting section side when not subjected to external force, allowing the two clamping plates 85 to move closer together. Applying external force through the pressing section 83 opens the clamping plate 85, which is then clamped onto the outer surface of the base plate 4 and the soft ceramic, thereby fixing the connector 8 and achieving a better blowing process.

[0043] In this embodiment, the three-dimensional relief soft porcelain is processed through the following steps:

[0044] (1) Base plate fabrication: Carve on the surface of a solid plate to create a relief convex mold, cover the surface of the convex mold with thermoplastic silicone, and then heat it to the melting point of the thermoplastic silicone to make the thermoplastic silicone melt into a fluid and completely adhere to the surface of the convex mold. After stabilization, allow it to cool naturally, peel off the reshaped thermoplastic silicone, and obtain a base plate 4 with a relief concave mold; In this embodiment, the thermoplastic silicone is a blend of vinyl silicone rubber and thermoplastic resin with a melting point of 150℃-200℃.

Place them in a mixer and add water at 10% of the total weight of the raw materials while stirring until the raw materials are fully dissolved and gelled, so that the viscosity reaches 2000 Pa·s. The water-based resin is acrylic resin. The heavy calcium carbonate is processed into 400-mesh powder and the quartz sand is screened into 80-mesh powder as raw materials.

[0046] (3) Baking and molding: When the card head 5 is inserted into the groove 43, its bottom inclined surface is in close contact with the inclined surface of the groove 43 to seal the groove 43, so that the surface of the base plate 4 is flat. Then, after spraying the release agent of the silicone system on the surface of the base plate 4, the raw material is injected into the base plate 4 and smoothed to make the top surface of the raw material flat and the thickness uniform. Then, it is sent into the baking mechanism 3 through the conveying mechanism 1 and baked at 80°C for 2 hours. After baking, it is taken out and placed to cool naturally to obtain the hardened soft ceramic and the combination of the base plate 4.

[0047] (4) Demolding of soft porcelain: Use an auxiliary mechanism to separate the soft porcelain from the base plate 4, so as not to damage the raised or recessed relief structure on the soft porcelain and the base plate 4; specifically, after pulling out the clip 5, use the connector 8 to align with the opening of the channel 43 so that the air outlet 81 is connected to the channel 43, and use the clamping plate 85 of the clamping member to clamp the outer side of the base plate 4 and the soft porcelain, thereby fixing the connector 8 and ensuring that the adhesive layer 9 of the connector is in close contact with the base plate 4 and the side of the soft porcelain; then turn on the fan 6 to blow air in, so that the base plate 4 in this area is separated from the soft porcelain. Repeat the above operation at each channel 43, and then the soft porcelain and the base plate 4 can be separated manually.

[0048] (5) Printing and coloring: Use a printer to print and color the relief on the surface of the soft porcelain to produce a three-dimensional relief soft porcelain product.

[0053] (3) Baking and molding: First, spray the release agent of the silicone system on the surface of the base plate 4, then inject the raw material into the base plate 4, sweep it to make the top surface of the raw material flat and the thickness uniform, and then send it into the baking mechanism 3 through the conveying mechanism 1. Bake at 80°C for 4 hours. After baking, take it out and let it cool naturally to obtain the hardened soft ceramic and the combination of the base plate 4.

[0054] (4) Demolding of soft porcelain: Use an auxiliary mechanism to separate the soft porcelain from the base plate 4, so as not to damage the raised or recessed relief structure on the soft porcelain and the base plate 4; specifically, after pulling out the clip 5, use the connector 8 to align with the opening of the channel 43 so that the air outlet 81 is connected to the channel 43, and use the clamping plate 85 of the clamping member to clamp the outer side of the base plate 4 and the soft porcelain, thereby fixing the connector 8 and ensuring that the adhesive layer 9 of the connector is in close contact with the base plate 4 and the side of the soft porcelain; then turn on the fan 6 to blow air in, so that the base plate 4 in this area is separated from the soft porcelain. Repeat the above operation at each channel 43, and then the soft porcelain and the base plate 4 can be separated manually.

[0055] (5) Printing and coloring: Use a printer to print and color the relief on the surface of the soft porcelain to produce a three-dimensional relief soft porcelain product.

Base plate fabrication: Carve a relief mold onto the surface of a solid sheet material. Cover the surface of the mold with thermoplastic silicone, then heat it to the melting point of the thermoplastic silicone to melt it into a fluid and completely adhere it to the surface of the mold. After stabilization and natural cooling, remove the reshaped thermoplastic silicone to obtain a base plate with a relief mold. S2. Raw material mixing: Take the corresponding raw materials according to the following weight ratio: 10-30 parts of heavy calcium carbonate, 50-75 parts of quartz sand, and 5-20 parts of water-based resin. Place them in a mixer and add 10%-30% water by weight of the total weight of the raw materials while stirring until the raw materials are fully dissolved and gelled, achieving a viscosity of 2000-2800 kJ / L. Pa·s; S3, Baking and shaping: The raw material prepared in step S2 is injected into the base plate prepared in step S1, and the surface of the raw material is leveled to make the top surface flat and the thickness uniform. Then, it is sent into the baking mechanism through the conveying mechanism and baked at 80°C for 2 to 6 hours. After baking, it is taken out and placed to cool naturally to obtain a hardened soft porcelain and base plate combined. S4. Soft porcelain demolding: Use an auxiliary mechanism to separate the soft porcelain from the base plate, so as not to damage the soft porcelain and the raised or recessed relief structure on the base plate. S5. Printing and Coloring: Use a printer to print and color the relief on the surface of the soft porcelain, thereby producing a three-dimensional relief soft porcelain product.

4. The processing method for three-dimensional relief soft porcelain as described in claim 3, characterized in that: In step S2, the waterborne resin is one or a mixture of acrylic resin, waterborne polyurethane, and waterborne epoxy resin.

5. The processing method for three-dimensional relief soft porcelain as described in claim 3, characterized in that: In step S2, heavy calcium carbonate is processed into 400-mesh powder, and 80-120 mesh quartz sand powder is screened as raw material.

6. The processing method for three-dimensional relief soft porcelain as described in claim 3, characterized in that: In step S3, a release agent is first sprayed onto the surface of the base plate, and then the raw material prepared in step S2 is injected.
