Description

Technical Field

[0001] The invention relates to the technical field of ceramic decals, in particular to an automatic decal device for producing ceramic products. Background Art

[0002] Ceramic products are widely used in daily life, covering a variety of fields from daily-use ceramics, artistic ceramics to industrial ceramics. With the increasing market demand, the trend of personalization and diversification of ceramic products is becoming more and more obvious. Traditional ceramic decal methods, such as manual decals and simple transfer technology, are difficult to meet the needs of the modern fast-moving consumer market due to their low efficiency, long production cycle and high labor costs.

[0003] Existing ceramic decal technologies mainly include water transfer decals, screen printing, inkjet printing, etc. While these technologies improve the aesthetics and decorativeness of the ceramic surface, they also have shortcomings such as low production efficiency, complex operation and high requirements for technical personnel. For example, first, prepare a suitable ceramic substrate and special ink, and make a screen plate to transfer the design pattern to the screen. Next, modulate the ink and position the screen plate on the ceramic surface, and then use a scraper to apply the ink and transfer it to the ceramic part through the mesh. After printing is completed, the ceramic part is dried to remove excess solvent. Next, the dried ceramic part is placed in a kiln for high-temperature firing to firmly bond the ink to the ceramic surface. Finally, after the product has cooled, a 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 degree of flexibility and a scraper according to the appearance characteristics of the ceramic parts. In addition, the operator must have a certain degree of proficiency. When scraping the ink on the ceramic surface, it is necessary to master the appropriate force. Any carelessness may cause the pattern to be blurred and fail to achieve the expected printing effect.

[0031] Preferably, the abutment plates are located on both sides of the concave rod and are fixedly connected to limit strips, and the limit strips are used to limit the lateral movement of the concave rod along the abutment plates.

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

[0033] 1. By adjusting the shape of the screen assembly and the scraper device, if the surface of the ceramic piece is uneven, the pigment on the screen will flow from high to low. The pigment at the low point of the screen can be transported back to the high point through the distribution component, so as to evenly redistribute the pigment. With this method, the scraper device can adjust the shape of the scraper assembly according to the shape of the ceramic piece, and cooperate with the screen assembly to adjust the shape of the screen so that it fits closely with the surface of the ceramic piece, so that the pigment can be evenly printed on the ceramic piece through the pattern on the screen. In addition, the scraper device can be adjusted according to the shape of different ceramic pieces, which not only reduces the cost of making special scrapers, but also can quickly adapt to the changes in the shape of different ceramic pieces. The design of the distribution component ensures the uniform spreading of the pigment on the screen and avoids the problem of uneven printing patterns;

[0034] 2. When the scraping part is pressed down by the combing rod and contacts the outer wall of the ceramic part, the scraping part made of flexible material will be deformed accordingly. Since there are trapezoidal abutments and triangular abutments with circular grooves inside the scraping part, during the downward pressing process, the bottom of the bevel of the scraping part will deform first until the bottom edge of the trapezoidal abutments contacts the ceramic part through the screen and the scraping part. During the entire deformation process, the circular groove inside the triangular abutments will expand, thereby increasing the contact area between the scraping part and the ceramic part, reducing the stress on the ceramic part, and avoiding damage to the ceramic part. When the entire scraping part is in contact with the outer wall of the ceramic part, the combing rod is lifted upward, and the scraping part returns to its original shape. When printing, the scraping part adopting this design can not only increase the contact surface with the ceramic part, but also the triangular abutments and trapezoidal abutments on its inner wall can prevent it from folding to both sides after deformation;

[0035] 3. Through the cooperation of the scraper device and the telescopic component, the film part can be in close contact with the surface of the ceramic part. When 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 overlaps along 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 gradually be subjected to pressure. When the bottom of the film part contacts a hard object, the non-Newtonian liquid inside it will harden when subjected to shear force, thereby printing the pigment through the screen onto the surface of the ceramic part. In this way, the physical properties of the non-Newtonian liquid can be used to make the film part fit closely with the ceramic part when adjusting the position of the comb rod. When printing, the stress can be increased to make the film part harden, so that the pigment can be evenly printed on the surface of the ceramic part;

[0036] 4. When the comb rod moves downward along the middle frame plate, the convex surface of the ceramic piece will push the comb rod upward. When the comb rod contacts the lowest point of the concave surface of the ceramic piece, the adjustment is completed. In this process, the comb rod is lifted by the convex surface, and the embedded rod of the movable rod drives the movable rod to move laterally under the limit of the inclined groove. As the comb rod rises, the hose connected to the suction piece is gradually compressed, while the hose connected to the discharge piece is gradually released. The compression state of the hose depends on the position of the comb rod. In this way, when the hose on the suction piece side is compressed more, less pigment is sucked in, because this is the higher cross-sectional position of the ceramic piece, while the hose that is not compressed or compressed less absorbs more pigment because it is at a lower cross-sectional position. In this way, the amount of pigment sucked into the concave surface of the ceramic cross-section can be increased. When the pressure device pressurizes the material storage part, the pigment is discharged through the discharging part. Due to the inclined groove design, when the hose on one side of the suction part is compressed, the hose on the other side of the discharging part is released, thereby transferring the pigment from a lower place to a higher place again, thereby ensuring that the pigment is evenly printed on the surface of the ceramic part through the screen pattern during the printing process.

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] In order to better understand the automatic decal device for producing ceramic products provided in the embodiment of the present application, the application of the existing screen printing method in ceramic decals is briefly introduced below. At present, the screen printing method is to attach a flexible screen to the ceramic surface so that it is in close contact with the ceramic surface as much as possible. The pigment is placed on the screen, and then a special scraper that fits the outer surface of the ceramic bottle is used to scrape the pigment along the bottle body, thereby completing the decal step;

[0052] Since most ceramic shapes are designed with 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 screen to fit closely to their surface, which may result in poor printing effects. In addition, the shapes of ceramic bottles are diverse, and a special scraper is required each time, which is costly.

[0053] Example 1: Please refer to Figure 1-12 The present invention provides a technical solution: an automatic decal device for producing ceramic products, comprising:

[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 is worth noting that after adjusting the scraper device 20 to fit the outer wall of the ceramic piece, the screen assembly 40 can also cooperate with the scraper device 20 to change the shape of the screen 13, so that the screen 13 fits the ceramic piece along the axial direction of the ceramic piece;

[0062] A distribution component 50, wherein the distribution component 50 is disposed in the scraper device 20, and the distribution component 50 is used to redistribute the pigment at a lower position of the screen 13 to a higher position;

[0063] It is worth noting that after the screen 13 changes its shape in cooperation with the screen assembly 40 and the scraper device 20, if the surface of the ceramic piece has concave and convex surfaces, the pigment on the screen 13 will flow from high to low, and the pigment at the low part of the screen 13 can be sent to high through the distribution component 50, thereby achieving the purpose of redistributing the pigment. In this way, the scraper device 20 can adjust the shape of the scraper bar assembly 300 according to the shape of the ceramic piece, and the scraper device 20 can cooperate with the screen assembly 40 to adjust the shape of the screen 13, so that the screen 13 and the scraper bar assembly 300 are in perfect contact with the ceramic piece, and the pigment can be evenly printed on the ceramic piece through the pattern on the screen 13, and the scraper device 20 can change its shape according to different ceramic pieces, reducing the cost of making special scrapers, and can quickly adjust the shape of the scraper bar assembly 300 according to the shape of different ceramic pieces. The design of the distribution component 50 can make the pigment evenly spread on the screen 13, avoiding uneven printing of stickers.

[0064] Further Figure 4 , Figure 5 and Figure 6 As shown, it is worth to explain in detail that the scraper strip assembly 300 includes:

[0065] The scraping part 301 is made of a flexible material, and the scraping part 301 is made of a polyurethane PU material. The top of the scraping part 301 is fixedly connected to the bottom of the inserting and combing rod 23. The cross-sectional shape of the scraping part 301 is a right triangle. The right-angled side of one side of the scraping part 301 is an open end. The inner wall array of the right-angled side of the top of the scraping part 301 is fixedly connected with a trapezoidal abutment 302. The inner wall hypotenuse array of the scraping part 301 is fixedly connected with a triangular abutment 303. The end of the triangular abutment 303 is fixedly connected to the right-angled side of the top of the scraping part 301. The bottom of the trapezoidal abutment 302 is parallel to the right-angled side of the top of the scraping part 301. A circular groove 304 is provided in the triangular abutment 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 is worth noting that after the scraper device 20 cooperates with the telescopic component 310 and the film part 317 to be in close contact with the surface of the ceramic part, when printing, the ceramic part needs to be driven to rotate by the workpiece operating device 11, and at the same time, the screen assembly 40 drives the screen 13 to move horizontally, so that the pattern on the screen 13 can be gradually overlapped along the surface of the ceramic part. At this time, the film part 317 can be gradually pressed down by the electric cylinder 21 The middle frame plate 22 is gradually pressed down, and when there is a hard object at the bottom of the film part 317, the non-Newtonian liquid inside it will harden when it is subjected to shear force, thereby printing the pigment through the screen 13 on the surface of the ceramic part. In this way, the physical properties of the non-Newtonian liquid can be used to adjust the position of the comb rod 23 so that the film part 317 is closely fitted with the ceramic part. When printing, the stress can be increased to make the film part 317 harden, so that the pigment is evenly printed on the surface of the ceramic part.

[0073] According to the above embodiment, the present solution also has a third embodiment: the screen assembly 40 includes:

[0074] Concave rods 41, the concave rods 41 are slidably connected to the inserting and combing rods 23, the ends of the concave rods 41 are fixedly connected to the surface of the screen 13, and the number of the concave rods 41 is the same as the number of the inserting and combing rods 23;

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

[0076] The abutment plates 43 are two symmetrically arranged about the screen 13, and the surface of the abutment plates 43 is provided with anti-slip grooves. An electric cylinder 44 is arranged on one side of the abutment plate 43. The internal telescopic rod of the electric cylinder 44 is fixedly connected to the outer wall of the abutment plate 43, and the outer shell of the electric cylinder 44 is fixedly connected to the fixing frame 12. In the process of bonding the comb rod 23 with the ceramic surface, the concave rod 41 moves with the movement of the comb rod 23. Since the two ends of the concave rod 41 are fixedly connected to the screen 13, the screen 13 also changes its shape and bonds with the outer surface of the ceramic part. In this way, when printing on a concave ceramic part, the screen 13 can be bonded to the concave surface of the ceramic. In this way, when printing, the scraper device 20 cooperates with the scraper bar assembly 300 to scrape back and forth more stably.

[0077] Further Figure 7 , Fig. 9 and Fig.10 As shown, it is worth to explain in detail that the distribution component 50 includes:

[0078] A material suction member 51 is arranged at the bottom of the inserting and combing rod 23, a material discharging member 52 is arranged at the bottom of the inserting and combing rod 23 and on the upper side of the material suction member 51, a squeezing device 53 is arranged at the top of the inserting and combing rod 23 on the middle frame plate 22, a peristaltic member 54 is arranged at the top of the middle frame plate 22, a material storage member 55 is arranged at one side of the peristaltic member 54 on the middle frame plate 22, and a pressurizing device 56 is arranged at the top of the material storage member 55;

[0079] It should be noted that during the printing process, the peristaltic member 54 can be started to suck the pigment into the storage member 55 through the suction member 51, and then the pigment can be discharged again through the discharge member 52 through the pressurizing device 56. During this process, the extrusion device 53 can cooperate with the combing rod 23 to transport the pigment in the pigment depression to the convex apex or both sides of the convex surface.

[0080] Further Figure 8 As shown, it is worth to explain in detail that the extrusion device 53 comprises:

[0081] The shell 531 is fixedly connected to the bottom of the middle frame plate 22. The shell 531 has inclined grooves 532 on both sides. The inclined grooves 532 are parallel to each other. The top of the inserting and combing rod 23 is fixedly connected to a connecting ear 533. The connecting ear 533 is slidably connected to a movable rod 534. The two ends of the movable rod 534 are rotatably connected to rolling wheels 535. The two ends of the movable rod 534 are fixedly connected to embedded rods 536. The embedded rods 536 are arranged on the shell 531. In the chute 532, hoses 537 are provided on the inner walls of both sides of the shell 531, the rolling wheel 535 is in contact with the hose 537, the bottom of the hose 537 is respectively connected with the suction piece 51 and the discharge piece 52, the top of the hose 537 connected with the suction piece 51 is connected with the storage piece 55, and a one-way valve is provided at the connected position, the pigment can flow from the hose 537 into the storage piece 55, and the end of the hose 537 on the discharge piece 52 is connected with the bottom of the storage piece 55;

[0082] It should be noted that when the comb rod 23 moves downward along the middle frame plate 22, the convex surface of the ceramic piece will push the comb rod 23 upward. When the comb rod 23 at other positions abuts against the lowest point of the concave surface of the ceramic piece, the adjustment is completed. In this process, when the comb rod 23 on the convex surface is pushed upward, the embedded rods 536 on both sides of the movable rod 534 on the comb rod 23 are limited by the inclined groove 532, which drives the movable rod 534 to move laterally along the connecting ear 533. As the comb rod 23 is pushed upward, the hose 537 connected to the suction piece 51 is gradually compressed, and the hose 537 connected to the discharge piece 52 is gradually released from the compressed state. The specific compression state needs to be judged according to the actual position of the comb rod 23. In this way, the peristaltic piece 54 is not compressed too much when it is working. The amount sucked in by the hose 537 through the suction piece 51 is small because this place is at a higher position of the ceramic cross-section, while the amount sucked in by the hose 537 that is not compressed or less compressed is larger. Therefore, this place is at a lower position of the ceramic cross-section. 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 storage piece 55, the storage piece 55 discharges the pigment through the discharging piece 52 on the hose 537. Due to the design of the inclined groove 532, when the hose 537 on one side of the suction piece 51 is compressed, the hose 537 of the discharging piece 52 on the other side is decompressed, thereby transferring the pigment from the lower part of the ceramic cross-section to the higher part, so that during the printing process, the pigment can be evenly passed through the pattern on the screen 13 and printed on the surface of the ceramic.

[0083] Further Fig.11 As shown, it is worth to explain in detail that the peristaltic member 54 includes:

[0084] A peristaltic rod 541, one end of which is provided with a servo motor 542, the housing of which is fixedly connected to the middle frame plate 22, an array of connecting plates 543 is provided on the peristaltic rod 541, a circumferential array of peristaltic wheels 544 is provided on the connecting plates 543, the peristaltic wheels 544 are rotatably connected to the connecting plates 543, the peristaltic wheels 544 abut against the hose 537, and a semicircular plate 545 is provided on the upper side of the connecting plates 543;

[0085] It should be noted that, by starting the servo motor 542 to drive the peristaltic rod 541 to rotate, the connecting disk 543 arranged in an array on the peristaltic rod 541 rotates accordingly, and the connecting disk 543 drives the peristaltic wheel 544 to revolve around the connecting disk 543 as the center of the circle. The peristaltic wheel 544 cooperates with the semicircular plate 545 to squeeze the hose 537 connected to the suction piece 51 in turn. In this way, the hose 537 is squeezed in turn to form a moving pressure point. When the peristaltic wheel 544 leaves a certain point, the hose 537 reopens. The suction force generated in this process sucks the paint into the hose 537.

[0086] Further Fig. 9 As shown, it is worth to explain in detail that the suction piece 51 and the discharging piece 52 are both made of rubber, the suction piece 51 is flat and opens downward, and the discharging piece 52 is flat;

[0087] It should be noted that by making the suction piece 51 and the discharging piece 52 out of rubber, it is convenient to scrub them after use, and by designing the suction piece 51 to open downward, this design facilitates the suction piece 51 to absorb more paint.

[0088] Further Figure 3 , Figure 5 and Figure 7 As shown, it is worth explaining in detail that the sliding connection part between the comb rod 23 and the middle frame plate 22 is non-circular. By designing the sliding connection part between the comb rod 23 and the middle frame plate 22 to be non-circular, the comb rod 23 is more stable and less likely to rotate when moving up and down along the middle frame plate 22.

[0089] Further Figure 5 As shown, it is worth to explain in detail that the abutment plates 43 are located at both sides of the concave rod 41 and are fixedly connected to the limit strips 401, and the limit strips 401 are used to limit the lateral movement of the concave rod 41 along the abutment plates 43;

[0090] It should be noted that by providing the limiting strips 401 on both sides of the concave rod 41 on the abutment plate 43, the design of the limiting strips 401 can prevent the concave rod 41 from shifting in the lateral direction, thereby making the screen 13 more stably fixed.
