Description

Technical Field

[0001] The present invention relates to the technical field of ceramic decal, and particularly to an automatic decal device for the production of ceramic products. Background Art

[0002] Ceramic products are widely used in daily life, covering multiple fields such as household ceramics, art ceramics, and industrial ceramics. With the increasing market demand, the trend of personalization and diversification of ceramic products has become more obvious. Traditional ceramic decal methods, such as manual decal and simple transfer technology, are difficult to meet the needs of the modern fast-consuming market due to low efficiency, long production cycle, and high labor cost.

[0003] Existing ceramic decal technologies mainly include water transfer decal, screen printing, inkjet printing, etc. While these technologies improve the aesthetics and decorativeness of the ceramic surface, they also have deficiencies such as low production efficiency, complex operation, and high requirements for technicians. For example, first, prepare a suitable ceramic substrate and special ink, and make a screen plate, then transfer the design pattern onto the screen plate. Next, modulate the ink and position the screen plate on the ceramic surface, and then use a squeegee to apply the ink, which is transferred through the mesh holes onto the ceramic part. After printing, the ceramic part is dried to remove the excess solvent. Then, the dried ceramic part is put into a kiln for high-temperature firing to firmly bond the ink to the ceramic surface. Finally, after the product cools down, quality inspection is carried out to ensure the consistency and quality of the printing effect.

[0004] However, existing ceramic parts often have concave and convex surfaces. When using screen printing to decal such ceramic parts, it is necessary to select a screen with a certain flexibility and a squeegee according to the shape characteristics of the ceramic part. In addition, the operator also needs to have a certain degree of proficiency. When scraping the ink onto the ceramic surface, appropriate force must be mastered. If there is a slight mistake, it may cause the pattern to be blurred and the expected printing effect cannot be achieved.

[0005] Therefore, we propose an automatic decal device for the production of ceramic products. Summary of the Invention

[0031] Preferably, limiting strips are fixedly connected to both sides of the abutting plate, and the limiting strips are used to limit the lateral movement of the concave-shaped rod along the abutting plate.

[0032] The present invention has at least the following beneficial effects:

[0033] 1. By adjusting the shapes of the screen assembly and the squeegee device, if the surface of the ceramic part is uneven, the pigment on the screen will flow from high places to low places. Through the distribution assembly, the pigment at the low part of the screen can be conveyed back to the high part, so as to evenly redistribute the pigment. By adopting this method, the squeegee device can adjust the shape of the squeegee assembly according to the shape of the ceramic part, and cooperate with the screen assembly to adjust the shape of the screen so that it fits tightly with the surface of the ceramic part, so that the pigment can be evenly printed on the ceramic part through the pattern on the screen. In addition, the squeegee device can be adjusted according to different shapes of ceramic parts, which not only reduces the cost of making special squeegees, but also can quickly adapt to the shape changes of different ceramic parts. The design of the distribution assembly ensures the even spreading of the pigment on the screen and avoids the problem of uneven printed patterns;

[0034] 2. When the insertion comb rod drives the scraping part to press down and contact the outer wall of the ceramic part, the scraping part made of flexible material will deform accordingly. Since there are trapezoidal abutting parts and triangular abutting parts with round grooves inside the scraping part, during the pressing process, the bottom of the hypotenuse of the scraping part will deform first until the bottom edge of the trapezoidal abutting part contacts the ceramic part through the screen and the scraping part. During the entire deformation process, the round groove in the triangular abutting part will expand, thereby increasing the contact area between the scraping part and the ceramic part, reducing the stress on the ceramic part, and avoiding damaging the ceramic part. When the entire scraping part fits with the outer wall of the ceramic part, the insertion comb rod is lifted upward, and the scraping part returns to its original shape. The scraping part designed in this way can not only increase the contact surface with the ceramic part during printing, but also the triangular abutting part and trapezoidal abutting part on its inner wall can prevent it from folding to both sides after deformation;

[0035] 3. Through the cooperation of the squeegee device and the telescopic assembly, the film part can be in close contact with the surface of the ceramic part. During printing, it is necessary to drive the ceramic part to rotate through the workpiece operating device, and at the same time, the screen assembly drives the screen to move horizontally, so that the pattern on the screen gradually coincides with the surface of the ceramic part. At this time, the middle frame plate is gradually pressed down by the electric cylinder, and the film part will be gradually stressed. When the bottom of the film part touches a hard object, the non-Newtonian liquid inside it will harden when subjected to shear force, so as to print the pigment through the screen on the surface of the ceramic part. By adopting this method, the physical properties of the non-Newtonian liquid can be utilized to make the film part fit tightly with the ceramic part when adjusting the position of the insertion comb rod. During printing, the stress can be increased to harden the film part, so as to evenly print the pigment on the surface of the ceramic part;

[0036] 4. When the inserting comb rod moves downward along the middle frame plate, the convex surface of the ceramic part will push the inserting comb rod upward. When the inserting comb rod touches the lowest point of the concave surface of the ceramic part, the adjustment is completed. During this process, the inserting comb rod is pushed upward by the convex surface, and the inserting rod of the movable rod drives the movable rod to move horizontally under the limitation of the inclined groove. As the inserting comb rod rises, the hose connecting the material suction part is gradually pressed, while the hose connecting the material discharging part is gradually released. The pressing state of the hose depends on the position of the inserting comb rod. In this way, when the hose on the material suction part side is pressed more, less pigment is inhaled because this is the position of the higher cross-section of the ceramic part, while more pigment is inhaled by the hose that is not pressed or is pressed less because it is in the position of the lower cross-section. In this way, the amount of pigment inhaled at the concave surface of the ceramic cross-section can be increased. When the pressurizing device pressurizes the material storage part, the pigment is discharged through the material discharging part. Due to the inclined groove design, when the hose on the material suction part side is pressed, the hose on the other side of the material discharging part is released, so as to transfer the pigment from the lower part to the higher part again, thus ensuring that the pigment is evenly printed on the surface of the ceramic part through the screen pattern during the printing process.

Detailed implementation manners

[0050] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0051] To better understand an automatic decal device for ceramic product production provided in the embodiments of the present application, the application of the existing screen printing method in ceramic decal is briefly introduced below. Currently, in the screen printing method, a flexible wire mesh is attached to the surface of the ceramic to make it as close as possible to the ceramic surface. The pigment is placed on the wire mesh, and then a special squeegee that fits the outer surface of the ceramic bottle is used to scrape the pigment along the bottle body, thus completing the decal step;

[0052] Since most ceramic shape designs have central axis symmetry, the bottle body is formed by rotating around the central axis. For ceramics with concave surfaces, it is difficult for the flexible wire mesh to closely adhere to their surfaces, which may result in poor printing effects. In addition, the shapes of ceramic bottle bodies are diverse, and a special squeegee needs to be used each time, resulting in high costs.

[0053] Embodiment 1: Please refer to Figures 1-12 , the present invention provides a technical solution: an automatic decal device for ceramic product production, including:

[0054] A base 10, on which a workpiece operating device 11 is disposed, the workpiece operating device 11 is used to fix the ceramic piece, and to drive the ceramic piece to move up and down along the vertical direction of the base 10, and to drive the ceramic piece to rotate about its axis;

[0055] It should be noted that before decals are applied, the ceramic needs to be fixed on the workpiece operating device 11, and it is necessary to ensure that it can rotate along the central axis after being fixed. The workpiece operating device 11 here is a prior art and will not be described in detail here.

[0056] The wire mesh 13 is made of a flexible material, and the wire mesh 13 is made of synthetic materials such as polyester or nylon;

[0057] A fixing frame 12, wherein the fixing frame 12 is fixedly connected to the top of the base 10;

[0058] The scraper device 20 is provided with two groups in total, and the scraper device 20 includes an electric cylinder 21, the outer shell of the electric cylinder 21 is fixedly connected to the top of the fixed frame 12, the end of the telescopic rod inside the electric cylinder 21 is fixedly connected to the middle frame plate 22, and a plurality of inserting and combing rods 23 are arranged in an array at the bottom of the middle frame plate 22, and the inserting and combing rods 23 are slidably connected along the vertical direction of the middle frame plate 22, and a scraper bar assembly 300 is arranged at the bottom end of the inserting and combing rod 23, and a clamping plate 24 is slidably connected to one side of the middle frame plate 22, and the clamping plate 24 is fixedly connected with a number of fixing clamps 25 equal to the number of the inserting and combing rods 23, and the clamping plate 24 is fixed to the middle frame plate 22 by bolts, and a spring 26 is arranged at the top end of the inserting and combing rod 23, one end of the spring 26 is fixedly connected to the end of the inserting and combing rod 23, and the other end of the spring 26 is fixedly connected to the bottom of the middle frame plate 22;

[0059] It should be noted that, in the initial state, it is necessary to ensure that the extension line of the middle frame plate 22 in the scraper device 20 passes through the central axis of the ceramic piece. Before printing, the bolts on the positioning plate 24 are unscrewed to separate the fixing card 25 on the positioning plate 24 from the combing rod 23. At this time, the combing rod 23 is released from the restriction, and the middle frame plate 22 is driven downward by the internal telescopic rod of the electric cylinder 1 21, so that the end of the combing rod 23 contacts the outer wall of the ceramic piece through the screen 13. During the process of continuing to press down, the spring 26 will stretch until all the combing rods 23 contact the outer wall of the ceramic piece. At this time, the electric cylinder 1 21 stops working, and the bolts are tightened again so that the fixing card 25 on the positioning plate 24 fixes the combing rod 23, and the scraper bar assembly 300 at the bottom of the combing rod 23 changes shape accordingly. Similarly, the scraper device 20 on the other side is set in the same way as above.

[0060] A screen assembly 40, which is disposed at the lower side of the inserting and combing rod 23, and can cooperate with the scraper device 20 to change the shape of the screen 13;

[0061] It should be noted that after adjusting the squeegee device 20 to fit the outer wall of the ceramic part, the screen assembly 40 can also cooperate with the squeegee device 20 to change the shape of the screen 13, so that the screen 13 fits the ceramic along the axial direction of the ceramic part;

[0062] A distribution assembly 50, the distribution assembly 50 is arranged in the squeegee device 20, and the distribution assembly 50 is used to redistribute the pigment at the lower part of the screen 13 to the higher part;

[0063] It should be noted that after the screen 13 changes its shape in cooperation with the screen assembly 40 and the squeegee device 20, if the surface of the ceramic part has concave and convex surfaces, the pigment on the screen 13 will flow from the higher part to the lower part. The distribution assembly 50 can send the pigment at the lower part of the screen 13 to the higher part, so as to achieve the purpose of redistributing the pigment. In this way, the squeegee device 20 can adjust the shape of the squeegee strip assembly 300 according to the shape of the ceramic part, and the squeegee device 20 can cooperate with the screen assembly 40 to adjust the shape of the screen 13, so that the screen 13 and the squeegee strip assembly 300 are tightly fitted when contacting the ceramic part, so that the pigment can be evenly printed on the ceramic part through the pattern on the screen 13. Moreover, the squeegee device 20 can change its shape according to different ceramic parts, reducing the cost of making special squeegees, and can quickly adjust the shape of the squeegee strip assembly 300 according to the shape of different ceramic parts. The design of the distribution assembly 50 can make the pigment evenly spread on the screen 13, avoiding uneven printing of stickers.

[0064] Furthermore, as shown in Figure 4 、 Figure 5 and Figure 6 specifically, the squeegee strip assembly 300 includes:

[0065] A scraping part 301, the scraping part 301 is made of a flexible material, the scraping part 301 is made of polyurethane PU material, the top of the scraping part 301 is fixedly connected to the bottom of the comb rod 23, the cross-sectional shape of the scraping part 301 is a right triangle, one right-angled side of the scraping part 301 is an open end, a trapezoidal abutting part 302 is fixedly connected in an array on the inner wall of the top right-angled side of the scraping part 301, a triangular abutting part 303 is fixedly connected in an array on the inner wall of the hypotenuse of the scraping part 301, the end of the triangular abutting part 303 is fixedly connected to the top right-angled side of the scraping part 301, the bottom of the trapezoidal abutting part 302 is parallel to the top right-angled side of the scraping part 301, and a circular groove 304 is opened in the triangular abutting part 303;

[0066] It should be noted that when the combing rod 23 drives the scraping portion 301 to press down and contact the outer wall of the ceramic part, the scraping portion 301 made of the flexible material is deformed accordingly. Since there is a trapezoidal abutment 302 inside the scraping portion 301 and a circular groove 304 is provided in the triangular abutment 303, the bottom of the oblique side of the scraping portion 301 is deformed first during the pressing process until the bottom side of the trapezoidal abutment 302 contacts the ceramic part through the wire mesh 13 and the scraping portion 301. During the whole deformation process, the triangular abutment 303 is deformed. The circular groove 304 in the part 303 is expanded accordingly, which can increase the contact area between the scraping part 301 and the ceramic part, reduce the stress on the ceramic part, and avoid damaging the ceramic part. When the entire scraping part 301 is in contact with the outer wall of the ceramic part, the comb rod 23 is lifted upward, and the scraping part 301 recovers its deformation. When the scraping part 301 with this design is printed, the contact area with the ceramic part can be increased, and the triangular abutment part 303 and the trapezoidal abutment part 302 on its inner wall can also avoid folding to both sides after deformation.

[0067] According to the above embodiment, the present solution also has a second embodiment: the scraper strip assembly 300 includes:

[0068] The telescopic assembly 310 is provided with several groups. The telescopic assembly 310 is provided between the inserting and combing rods 23. The telescopic assembly 310 includes:

[0069] A sliding cylinder 311, wherein both ends of the sliding cylinder 311 are slidably connected to a rotating cylinder 312, wherein the rotating cylinder 312 is rotatably connected to the bottom of the combing rod 23, wherein a vertical groove 313 is provided in the middle of the sliding cylinder 311, wherein the sliding cylinder 311 is located in the vertical groove 313 and is slidably connected to a T-plate 314, wherein the sliding cylinder 311 is located in the vertical groove 313 and is fixedly connected to an air pipe port 315 at the top of the vertical groove 313, wherein an air pump 316 is fixedly connected to one side of the middle frame plate 22, wherein an air outlet of the air pump 316 is connected to the air pipe port 315;

[0070] It should be noted that when the combing rod 23 is in contact with the surface of the ceramic piece, the distance between the ends of the combing rod 23 increases, the rotating cylinder 312 rotates accordingly, and the sliding cylinder 311 can also move along the direction of the rotating cylinder 312. By starting the air pump 316, the air pump 316 sends gas into the air pipe port 315. At this time, the T-plate 314 slidably connected to the sliding cylinder 311 moves along the direction of the vertical groove 313 of the sliding cylinder 311 under the action of pressure.

[0071] A thin film member 317, wherein the inside of the thin film member 317 is hollow, and the top of the thin film member 317 is adhered to the T-plate 314. The thin film member 317 is made of a wear-resistant and soft material, and the inside of the thin film member 317 is filled with a non-Newtonian liquid, specifically a shear thickening fluid;

[0072] It should be noted that after the scraping device 20 cooperates with the telescopic component 310 and the film member 317 is in close contact with the surface of the ceramic member, during printing, the workpiece operating device 11 needs to drive the ceramic member to rotate, and at the same time the screen component 40 drives the screen 13 to move horizontally, so that the pattern on the screen 13 gradually coincides along the surface of the ceramic member. At this time, the middle frame plate 22 is gradually pressed down by the first electric cylinder 21, so that the film member 317 is gradually subjected to pressure. When there is a hard object at the bottom of the film member 317, the non-Newtonian liquid inside it will harden when subjected to shear force, so as to print the pigment through the screen 13 on the surface of the ceramic member. By using this method, the physical properties of the non-Newtonian liquid can be utilized. When adjusting the position of the comb-shaped rod 23, the film member 317 can be closely attached to the ceramic member. When printing, the stress can be increased to make the film member 317 harden, so as to evenly print the pigment on the surface of the ceramic member.

[0073] According to the above embodiments, this solution also has Embodiment 3: The screen assembly 40 includes:

[0074] A concave character rod 41, the concave character rod 41 is slidably connected to the comb-shaped rod 23, both ends of the concave character rod 41 are fixedly connected to the surface of the screen 13, and the number of the concave character rods 41 is the same as the number of the comb-shaped rods 23;

[0075] A leak-proof plate 42, the leak-proof plate 42 is fixedly connected to the outer wall of the concave character rod 41 on the outside, the bottom of the leak-proof plate 42 is adhered to the surface of the screen 13, and the leak-proof plate 42 can prevent the pigment from flowing out of the screen 13 on both sides during the printing process;

[0076] A butting plate 43, there are two butting plates 43 symmetrically arranged with respect to the screen 13, anti-slip lines are provided on the surface of the butting plate 43, an electric cylinder two 44 is arranged on one side of the butting plate 43, the telescopic rod inside the electric cylinder two 44 is fixedly connected to the outer wall of the butting plate 43, and the housing of the electric cylinder two 44 is fixedly connected to the fixed frame 12. During the process of the comb-shaped rod 23 fitting with the ceramic surface, the concave character rod 41 moves with the movement of the comb-shaped rod 23. Since both ends of the concave character rod 41 are fixedly connected to the screen 13, the screen 13 also changes its shape to fit the outer surface of the ceramic member accordingly. By using this method, when printing a concave ceramic member, the screen 13 can fit with the ceramic concave surface, so that during printing, the scraping device 20 cooperates with the scraping bar assembly 300 to scrape back and forth more stably.

[0077] Furthermore, as shown in Figure 7 、 Figure 9 and Figure 10 It is worth specifically explaining that the dispensing assembly 50 includes:

At the top of the comb inserting rod 23 on the middle frame plate 22, a squeezing device 53 is provided. At the top of the middle frame plate 22, a peristaltic member 54 is provided. At one side of the peristaltic member 54 on the middle frame plate 22, a material storage member 55 is provided. At the top of the material storage member 55, a pressurizing device 56 is provided;

[0079] It should be noted that during the printing process, when the peristaltic member 54 is started, the pigment can be sucked into the material storage member 55 through the material suction member 51, and then discharged through the material discharging member 52 again by the pressurizing device 56. During this process, the squeezing device 53 can cooperate with the comb inserting rod 23 to convey the pigment in the concave part of the pigment to the convex vertex or both sides of the convex surface.

[0080] Further, as Figure 8 shown, specifically, the squeezing device 53 includes:

[0081] A housing 531, the housing 531 is fixedly connected to the bottom of the middle frame plate 22. Oblique grooves 532 are formed on both sides of the housing 531, and the oblique grooves 532 are parallel to each other. A connecting ear 533 is fixedly connected to the top of the comb inserting rod 23. A movable rod 534 is slidably connected to the connecting ear 533. Rolling wheels 535 are rotatably connected to both ends of the movable rod 534. Inserting rods 536 are fixedly connected to both ends of the movable rod 534, and the inserting rods 536 are arranged in the oblique grooves 532 of the housing 531. Hose pipes 537 are arranged on the inner walls of both sides of the housing 531. The rolling wheels 535 are in contact with the hose pipes 537. The bottom parts of the hose pipes 537 are respectively communicated with the material suction member 51 and the material discharging member 52. The top end of the hose pipe 537 communicated with the material suction member 51 is communicated with the material storage member 55, and a one-way valve is arranged at the communicating position, and the pigment can flow into the material storage member 55 from the hose pipe 537. The end part of the hose pipe 537 on the material discharging member 52 is communicated with the bottom of the material storage member 55;

[0082] It should be noted that when the inserting comb rod 23 moves downward along the middle frame plate 22, the convex surface of the ceramic part will push the inserting comb rod 23 upward. When the inserting comb rod 23 at other positions abuts against the lowest point of the concave surface of the ceramic part, the adjustment is completed. During this process, when the inserting comb rod 23 on the convex surface is pushed upward, due to the limiting action of the inserting rods 536 on both sides of the movable rod 534 on the inserting comb rod 23 in the inclined slots 532, the movable rod 534 is driven to move horizontally along the connecting ear 533. As the inserting comb rod 23 is pushed upward, the hose 537 connected to the material suction part 51 is gradually compressed, while the hose 537 connected to the material discharging part 52 is gradually released from the compressed state. The specific compression state needs to be judged according to the actual position of the inserting comb rod 23. In this way, when the peristaltic part 54 is working, the hose 537 that is overly compressed sucks less material through the material suction part 51 because this is at a position with a relatively high cross-section of the ceramic part, while the hose 537 that is not compressed or is less compressed sucks more material. Therefore, this is at a position with a relatively low cross-section of the ceramic part. In this way, the amount of pigment sucked into the concave surface of the ceramic cross-section can be increased. When the pressurizing device 56 pressurizes the material storage part 55, the material storage part 55 discharges the pigment through the material discharging part 52 on the hose 537. Due to the design of the inclined slots 532, when the hose 537 on one side of the material suction part 51 is compressed, the hose 537 of the material discharging part 52 on the other side is decompressed, so as to transfer the pigment from the place with a relatively low cross-section of the ceramic part to the place with a relatively high cross-section again. Thus, during the printing process, the pigment can be evenly printed on the surface of the ceramic part through the pattern on the screen 13.

[0083] Furthermore, as Figure 11 shown, it is specifically worth noting that the peristaltic part 54 includes:

[0084] A peristaltic rod 541, one end of the peristaltic rod 541 is provided with a servo motor 542, the outer shell of the servo motor 542 is fixedly connected to the middle frame plate 22, the peristaltic rod 541 is provided with connecting disks 543 in an array, the connecting disks 543 are provided with peristaltic wheels 544 in a circumferential array, the peristaltic wheels 544 are rotatably connected to the connecting disks 543, the peristaltic wheels 544 abut against the hose 537, and a semi-circular plate 545 is arranged on the upper side of the connecting disk 543;

[0085] It should be noted that by starting the servo motor 542 to drive the peristaltic rod 541 to rotate, the connecting disks 543 arranged in an array on the peristaltic rod 541 rotate accordingly, the connecting disks 543 drive the peristaltic wheels 544 to revolve around the connecting disks 543 as the center. The peristaltic wheels 544 cooperate with the semi-circular plate 545 to sequentially squeeze the hose 537 connected to the material suction part 51. In this way, the hose 537 is sequentially squeezed to form a moving pressure point. When the peristaltic wheel 544 leaves a certain point, the hose 537 reopens, and the suction force generated during this process sucks the pigment into the hose 537.

[0086] Furthermore, asFigure 9 As shown, it is worth specifically noting that both the material suction member 51 and the material discharging member 52 are made of rubber. The material suction member 51 is flat and has an opening facing downward, and the material discharging member 52 is flat.

[0087] It should be noted that by making the material suction member 51 and the material discharging member 52 of rubber, it is convenient to scrub them after use. By designing the material suction member 51 with an opening facing downward, this design facilitates the material suction member 51 to suck more pigments.

[0088] Further, as shown in Figure 3 、 Figure 5 and Figure 7 As shown, it is worth specifically noting that the sliding connection part between the comb inserting rod 23 and the middle frame plate 22 is non-circular. By designing the sliding connection part between the comb inserting rod 23 and the middle frame plate 22 to be non-circular, the comb inserting rod 23 is more stable and not easy to rotate when moving up and down along the middle frame plate 22.

[0089] Further, as shown in Figure 5 As shown, it is worth specifically noting that the limiting strips 401 are fixedly connected to both sides of the concave-shaped rod 41 on the abutting plate 43, and the limiting strips 401 are used to limit the lateral movement of the concave-shaped rod 41 along the abutting plate 43;

[0090] It should be noted that by arranging the limiting strips 401 on both sides of the concave-shaped rod 41 on the abutting plate 43, the design of the limiting strips 401 can prevent the concave-shaped rod 41 from shifting laterally, thereby making the fixing of the wire mesh 13 more stable.

[0091] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0092] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
