Description

Technical Field

[0001] This invention relates to the field of ceramic product processing technology, and specifically to an intelligent glazing equipment for ceramic product processing. Background Technology

[0002] Glazing equipment in ceramic product processing is a specialized automated or semi-automated device used to uniformly and stably apply glaze slurry (a slurry of glaze mixed with water and other media) to the surface of ceramic bodies. It is a key piece of equipment in ceramic production, connecting the body forming and firing processes. Its core objective is to ensure that the glaze layer is of consistent thickness and complete coverage, laying the foundation for a high-quality glaze surface after subsequent firing.

[0003] Ceramic spray glazing is one of the most common processes in ceramic glazing. Its core principle is to atomize the glaze slurry using a high-pressure spray gun and evenly cover the surface of the ceramic body. Currently, when spray glazing onto conical ceramic products, the fixed spray angle of the nozzle prevents the nozzle from maintaining a perpendicular position to the angled surface of the ceramic product. When the nozzle sprays the glaze, the glaze covers the surface of the ceramic body in a conical spray pattern, and the concentration and particle density of the spray are most uniform in the direction perpendicular to the nozzle axis (i.e., the density is consistent in the "spray core area"). If the angle is 90°: the nozzle axis and the tangent at that point on the curved surface of the blank are completely coincident, the core area of ​​the glaze spray can accurately cover the surface of the blank, each area receives the same amount of glaze, and finally a glaze layer of uniform thickness is formed. If the angle deviates from 90° (such as tilting 30°-60°): the nozzle axis is not perpendicular to the surface of the blank, resulting in uneven coverage of the spray on the surface of the blank - the glaze accumulates (too thick) in the area near the nozzle, and the glaze is sparse (too thin) in the area away from the nozzle, which greatly affects the glaze quality. Summary of the Invention

[0025] The glazing mechanism 4 includes an electric slide rail 41. One end of the slider inside the electric slide rail 41 is fixedly connected to a moving plate 42.

A torque sensor 54 is also fixedly connected to the output end of the stirring motor 53. A feed pipe 55 is also fixedly connected to the bottom side wall of the storage box 51. The end of the feed pipe 55 away from the storage box 51 is connected to the buffer shell 44. A feed pump 56 is also installed on the feed pipe 55. The feed pump 56 is fixedly installed on the outer wall of the storage box 51.

[0027] The drying mechanism 6 includes a heating box 61 and a blower 62 fixedly installed on the upper end of the base 1. The heating box 61 and the blower 62 are connected by an air supply pipe 63. Multiple electric heating rods 64 are fixedly installed inside the heating box 61. The air outlet of the air supply pipe 63 is also fixedly connected to a drying spray pipe 65. Two side plates 66 are symmetrically fixedly connected to the upper end of the base 1. The same deflection block 67 is rotatably connected between the two side plates 66. The upper end of the deflection block 67 is fixedly connected to the lower end of the drying spray pipe 65. A synchronous motor 68 for driving the deflection pipe to rotate is fixedly installed on the side wall of one of the side plates 66.

[0028] When glazing ceramic products is required, the ceramic products are first placed on the support plate 22. The two laser rangefinders 47 on the glazing mechanism 4 operate, detecting the distance to the ceramic products. The PLC controller then controls the drive motor 34 to drive the transmission shaft 33 to rotate. The transmission shaft 33, connected to the electric slide rail 41 via the fixed block 35, drives the electric slide rail 41 to deflect until the two laser rangefinders 47 report that the distances to the ceramic products are equal. This indicates that the electric slide rail 41 is now parallel to the inclined surface of the ceramic product, and glazing is then initiated. The nozzle 45 is kept relatively perpendicular to the ceramic product. When the nozzle 45 sprays glaze, the glaze covers the surface of the body in a cone-shaped spray. The concentration and particle density of the spray are most uniform in the direction perpendicular to the axis of the nozzle 45 (i.e., the density of the core area of ​​the spray is consistent). This keeps the nozzle 45 perpendicular to the spraying surface, and the axis of the nozzle 45 completely coincides with the tangent of the curved surface of the ceramic product at that point. The core area of ​​the glaze spray can accurately cover the surface of the ceramic product, and each area receives the same amount of glaze, ultimately forming a glaze layer of uniform thickness, ensuring the quality of the spraying. The feed pump 56, in conjunction with the feed pipe 55, transports the glaze stored in the storage box 51 to the buffer shell 44, and then sprays it out through the nozzle 45. The rotary motor 21 drives the support plate 22 to rotate, thereby driving the ceramic product to rotate and completing the glazing work on the ceramic product. The electric slide rail 41 can drive the nozzle 45 to move along the inclined surface of the ceramic product, thereby completing the full glazing work on the ceramic product. The stirring motor 53 inside the glaze storage mechanism 5 works continuously. The stirring motor 53 drives the stirring rod 52 to rotate, thereby continuously and evenly mixing the glaze in the storage box 51 to prevent the particles in the glaze from settling and keep them suspended evenly. During the stirring process, the torque sensor 54 connected to the output end of the stirring motor 53 provides real-time feedback of the torque signal. The feedback torque signal represents the viscosity of the glaze. The greater the torque, the greater the viscosity of the glaze. The PLC controller adjusts the distance between the spray nozzle 45 and the ceramic product based on the obtained glaze viscosity using the electric actuator 43. This spraying distance is confirmed by the signal fed back by the laser rangefinder 47. Specifically, when the glaze viscosity is higher, the distance between the spray nozzle 45 and the ceramic product is closer. This is because high-viscosity glazes have poor fluidity and the particles tend to agglomerate after atomization. If the distance is too far, the particles tend to dry in the air and cannot adhere effectively. Therefore, the distance needs to be shortened to ensure that the particles quickly impact the body and adhere to it. When the viscosity of the glaze is lower, the distance between the nozzle 45 and the ceramic product should be greater. This is because low-viscosity glazes have strong fluidity. If the distance is too close, the glaze will easily flow and accumulate on the surface of the ceramic product. Therefore, it is necessary to increase the distance appropriately and use spray diffusion to reduce the amount of glaze per unit area. Furthermore, after the angle of the nozzle 45 is adjusted by the support deflection mechanism 3, the angle value of the electric slide rail 41 driven by the transmission shaft 33 is synchronously transmitted to the encoder 36 through the meshing transmission of the drive gear 38 and the driven gear 37. Then, the deflection angle of the electric slide rail 41 can be quickly determined by the rotation angle at the input end of the encoder 36, thereby confirming the specific size of the inclination of the inclined edge of the ceramic product. When the inclination of the ceramic product is greater, the initial working power of the feed pump 56 controlled by the PLC controller is greater. Because the nozzle 45 changes the spraying position from top to bottom, the greater the inclination of the ceramic product, the longer its circumference. When the rotational speed of the ceramic product driven by the rotary motor 21 is fixed, the linear speed of the ceramic product surface is greater, and the glazing power needs to be increased to ensure the amount of glaze adhesion. Moreover, whenever the electric slide rail 41 drives the nozzle 45 to move down to the next glazing position, the greater the inclination angle of the ceramic product, the greater the increase in the power of the feed pump 56, thereby ensuring the glazing quality. After the glazing process is completed, the PLC controller controls the drying mechanism 6 to operate. The air pump 62, in conjunction with the air supply pipe 63, draws air and sends it to the heating chamber 61. The air is heated by the electric heating rod 64, and the hot air is then delivered to the drying nozzle 65. The hot air acts on the surface of the ceramic product to quickly dry the glaze. While the deflection mechanism 3 adjusts the deflection angle of the nozzle 45, the PLC controller simultaneously controls the synchronous motor 68 to operate. The synchronous motor 68 drives the deflection block 67 to rotate, thereby synchronously adjusting the tilt angle of the drying nozzle 65. This continues until the drive motor 34 in the deflection mechanism 3 stops operating, at which point the synchronous motor 68 also stops working. The deflection angle of the drying nozzle 65 is kept the same as that of the electric slide rail 41, ensuring that the drying nozzle 65 is parallel to the surface of the ceramic product. The PLC controller automatically adjusts the heating temperature of the electric heating rod 64 based on the viscosity of the glaze. For low-viscosity glazes, the drying temperature is automatically increased because low-viscosity glazes are highly fluid and prone to sagging if the drying temperature is too low. Increasing the drying temperature accelerates the viscosity increase and prevents sagging. Conversely, for high-viscosity glazes, the drying temperature is automatically decreased because high-viscosity glazes have poor fluidity and are prone to defects due to rapid surface curing if the drying temperature is too high. Increasing the drying temperature extends the leveling time.
