Description

Technical Field

[0001] The present invention relates to the field of ceramic glazing, and particularly to a glazing device for ceramic sanitary ware. Background Art

[0002] Ceramics are utensils that we often use in daily life. They not only have diverse and beautiful shapes but are also very convenient to use. Glazing ceramics is to evenly cover the glaze slurry on the ceramic blank. The glaze layer can make the surface of the product smooth, impermeable, not easily contaminated, and can improve the mechanical strength, electrical properties, chemical stability, and thermal stability of the product to a certain extent. Currently, the commonly used ceramic glazing methods include: dipping method, pouring method, brushing method, and spraying method.

[0003] In the current ceramic spraying method, usually, the ceramic blank to be glazed is placed on a turntable. While the glazer regularly rotates the turntable, the glaze slurry is directly sprayed onto the ceramic blank through the nozzle of the glazing device. Although this spraying method has low requirements for the glazing device, each spraying operation requires clamping the ceramic blank on the turntable first, which not only increases the complexity of the spraying operation but also makes it difficult to efficiently achieve the assembly line spraying operation. Moreover, for ceramic sanitary ware with an arc-shaped groove on the glazing surface, it is necessary to spray each glazing area from the outer circle to the inner circle of the glazing surface of the ceramic sanitary ware one by one. The angle between each glazing area of this type of ceramic sanitary ware and the horizontal plane is different, resulting in a gradual change in the angle between the nozzle of the glazing device and different glazing areas, leading to different spraying effects of the nozzle on each glazing area, and making the glaze unable to be evenly distributed on the ceramic blank during the entire spraying process. Therefore, there is an urgent need to provide a new glazing device for ceramic sanitary ware to solve these problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a glazing device for ceramic sanitary ware to solve the above technical problems.

[0035] To make the objectives, features, and advantages of the present invention more obvious and understandable, the following provides a detailed description of the specific implementation manners of the present invention in conjunction with the accompanying drawings. Several embodiments of the present invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive

[0036] Refer to Figures 1 to 9 , an embodiment of the present invention provides a glazing device for ceramic sanitary ware. In this embodiment, the glazing surface of the ceramic sanitary ware 90 is in the shape of an arc groove, and the top view cross-section is in the shape of an annular ring. It can be a washbasin with a glazing surface in the shape of an arc groove

[0037] The glazing device includes a height adjustment mechanism 10, a positioning cylinder 20, a turntable 30, a horizontal displacement adjustment mechanism 40, an angle adjustment mechanism 50, a rotating mechanism 60, and a feeding mechanism 70

[0038] The height adjustment mechanism 10 includes a main motor 11, a support frame 12, a first screw rod 13, and an anti-rotation rod 14. The first screw rod 13 is rotatably connected to the output end of the main motor 11. The positioning cylinder 20 is connected to the first screw rod 13 and is slidably connected to the support frame 12 through the anti-rotation rod 14. The support frame 12 is fixedly connected to the main motor 11

[0039] The anti-rotation rod 14 is vertically and slidably inserted into the support frame 12. The bottom end of the anti-rotation rod 14 is fixedly connected to the positioning cylinder 20, and a nut 15 is screwed onto the top end. An overpressure spring 16 is provided between the nut 15 and the support frame 12. The overpressure spring 16 is in a compressed state and sleeved on the anti-rotation rod 14. Under the limiting action of the anti-rotation rod 14, the positioning cylinder 20 can only move up and down on the first screw rod 13, thereby facilitating the height adjustment of the positioning cylinder 20.

[0040] The support frame 12 includes a first support plate 121, a second support plate 122, and a vertical rod 123. The first support plate 121 is fixedly installed at the bottom of the main motor 11. The second support plate 122 is fixedly installed below the first support plate 121 through a plurality of the vertical rods 123. The nut 15 is located between the first support plate 121 and the second support plate 122. The overpressure spring 16 is compressed between the nut 15 and the second support plate 122, with the top contacting the nut 15 and the bottom contacting the second support plate 122.

[0041] It should be noted that the height adjustment mechanism 10 is used to adjust the height of the positioning cylinder 20, so as to realize the height adjustment of the nozzle 80. Among them, the setting of the overpressure spring 16 can play a certain supporting effect, which can reduce the overload load of the first screw rod 13 to a certain extent, and then reduce the pressure on the meshing surface between the first screw rod 13 and the positioning cylinder 20.

[0042] The positioning cylinder 20 includes a first positioning section 21, a limiting section 22, and a second positioning section 23 arranged in sequence from top to bottom. The radius of the limiting section 22 is larger than that of the first positioning section 21 and the second positioning section 23. The gear 63 is key-connected to the first positioning section 21. The turntable 30 and the end sleeve 44 are both rotatably sleeved on the second positioning section 23 through a rotating shaft. A limiting sleeve is respectively sleeved between the turntable 30 and the limiting section 22 and the end sleeve 44. The height of the bottom of the limiting section 22 is greater than the height of the top of the push rod 49.

[0043] The turntable 30 is rotatably sleeved outside the positioning cylinder 20.

[0044] The horizontal displacement adjusting mechanism 40 includes a first driving motor 41, a second screw rod 42, a connecting block 43, an end sleeve 44, three rocker arms 45, two sliding rods 46, two sliders 47, two end blocks 48 and three push rods 49. The first driving motor 41 and the two end blocks 48 are both slidably connected to the annular chute 31 near the outer ring at the bottom of the turntable 30. The second screw rod 42 and the two sliding rods 46 are arranged in a circumferential matrix below the turntable 30. One end of the second screw rod 42 is rotatably connected to the output end of the first driving motor 41, and the other end is rotatably connected to the end sleeve 44. One end of the sliding rod 46 is fixedly connected to the end block 48, and the other end is fixedly connected to the end sleeve 44. The end sleeve 44 is rotatably sleeved outside the positioning cylinder 20. The connecting block 43 is threadedly connected to the second screw rod 42. The two sliders 47 are respectively slidably connected to the two sliding rods 46. The connecting block 43 and the tops of the two sliders 47 are both connected with a push rod 49. The push rod 49 is slidably inserted into the inclined arc groove 32 on the surface of the turntable 30. The sides of the connecting block 43 and the two sliders 47 are both rotatably connected with a rocker arm 45. The end of the rocker arm 45 is connected with a spray head 80.

[0045] The inclined arc groove 32 is arc-shaped, one end is close to the inner ring of the turntable 30, and the other end is close to the outer ring of the turntable 30. The three inclined arc grooves 32 are obliquely arranged in a circumferential matrix on the surface of the turntable 30.

[0046] It should be noted that the horizontal displacement adjusting mechanism 40 is used to control the horizontal displacement of the spray head 80. The horizontal displacement adjusting mechanism 40 of this embodiment can not only control the horizontal displacement of one spray head 80, but also synchronously control the horizontal displacements of three or even more spray heads 80. When the spraying area of the ceramic sanitary ware 90 needs to be adjusted after spraying a circle, the horizontal displacement of the spray head 80 can be controlled to move synchronously in the direction close to or away from the center of the turntable 30 for spraying the next circle of spraying area, so as to ensure that every time the turntable 30 rotates one circle, the three spray heads 80 can work on the same circumference. One circular motion of the turntable 30 can achieve three spraying operations, avoiding repeated spraying of the same circle of spraying area by rotating multiple circles to ensure the spraying effect, greatly improving the spraying efficiency of the glaze on the ceramic sanitary ware 90. And in this embodiment, the number of components such as the inclined arc groove 32, the push rod 49 and the spray head 80 can be set according to the number of spraying times and the effect required for spraying, as long as the spray heads 80 are arranged in a circumferential array at the bottom of the turntable 30.

[0047] Specifically, driven by the first drive motor 41, the second screw 42 rotates, driving the connecting block 43 to move on the second screw 42. At this time, the push rod 49 on the top of the connecting block 43 not only limits the connecting block to keep the connecting block 43 moving on the second screw 42, but also can, under the action of the inclined arc groove 32, push the turntable 30 to drive the turntable 30 to rotate. Under the action of the other two inclined arc grooves 32, the other two push rods 49 are driven to move synchronously in the other two inclined arc grooves 32 respectively. Furthermore, the connecting block 43 and the nozzles 80 at the bottoms of the two sliders 47 can move synchronously towards or away from the center of the turntable 30 respectively, so that the three nozzles 80 can always be on the same circumference.

[0048] There are three sets of the angle adjustment mechanisms 50, which are respectively installed on the connecting block 43 and the two sliders 47, and are used to drive the rocker 45 to rotate, so as to adjust the outlet of the nozzle to face the glazing surface of the ceramic sanitary ware 90.

[0049] The angle adjustment mechanism 50 includes a rotating motor 51, a first rotating shaft 52 and a connecting rod 53. The rotating motor 51 is installed at the bottom of the connecting block 43. The first rotating shaft 52 is connected to the output end of the rotating motor 51. The first rotating shaft 52 is perpendicular to the rocker 45. The connecting rod 53 is L-shaped, with one end vertically connected to the first rotating shaft 52 and the other end slidably inserted into the slot 451 of the rocker 45.

[0050] It should be noted that since the glazing surface of the ceramic sanitary ware 90 in this embodiment is in the shape of an arc groove, and the angle between each glazing area and the horizontal plane is different. Therefore, when glazing different circles of glazing areas, in order to ensure the uniform spraying of the glaze, the angle of the nozzle 80 needs to be adjusted so that the outlet of the nozzle can face the glazing area of the ceramic sanitary ware 90. In this embodiment, the angle of the nozzle 80 is adjusted by the angle adjustment mechanism 50.

[0051] Specifically, when the angle of the nozzle 80 needs to be adjusted, the rotating motor 51 drives the first rotating shaft 52 to rotate, and the first rotating shaft 52 drives the connecting rod 53 to rotate. Then, the connecting rod 53 toggles the rocker 45 to rotate. Since the rocker 45 is rotatably connected to the side of the connecting block 43 or the slider 47 and will rotate around the connection point, when the connecting rod 53 toggles the rocker 45 to rotate, it will slide in the slot 451 of the rocker 45. The rotating motors 51 of the three sets of angle adjustment mechanisms 50 in this embodiment work synchronously.

[0052] The rotation mechanism 60 is installed on the turntable 30. The rotation mechanism 60 includes a second driving motor 61, a second rotating shaft 62, a gear 63, and a gear disc 64. The second driving motor 61 is fixedly installed at the bottom of the turntable 30. The gear disc 64 is connected to the second driving motor 61 through the second rotating shaft 62. The gear disc 64 is key-connected to the second rotating shaft 62. The gear 63 is sleeved outside the positioning cylinder 20, is key-connected to the positioning cylinder 20, and is located above the turntable 30. The outer side of the gear 63 meshes with the gear disc 64.

[0053] It should be noted that the rotation mechanism 60 is used to drive the turntable 30 to rotate around the center of the positioning cylinder 20, so that the horizontal displacement adjustment mechanism connected to the bottom of the turntable 30 can rotate around the center of the positioning cylinder 20, thereby driving the nozzle 80 to rotate around the center of the positioning cylinder 20.

[0054] Specifically, when spraying glaze on the same circle of glazing areas of the ceramic sanitary ware 90 in a rotating manner, the second driving motor 61 drives the second rotating shaft 62 to rotate and drives the gear disc 64 to rotate. Therefore, the gear disc 64 generates a thrust on the gear meshing surface of the gear 63. Since the gear 63 is key-connected to the positioning cylinder 20, the gear 63 cannot rotate. The gear 63 under the thrust applies a reverse thrust to the meshing surface of the gear disc 64, so that the gear disc 64 makes a circular motion around the center of the gear 63. The rotating gear disc 64 also drives the turntable to rotate around the center of the gear 63 (i.e., the center of the positioning cylinder 20), and further drives the nozzle 80 to rotate around the center of the positioning cylinder 20.

[0055] The feeding mechanism 70 is installed on the turntable 30 and is used to convey glaze to the nozzle 80. The feeding pipes of each nozzle 80 are connected to the discharge port 721 of the feeding mechanism 70. The hydraulic pressure at the discharge port 721 of the feeding mechanism 70 is kept constant, and a discharge valve is installed at the discharge port 721.

[0056] The feeding mechanism 70 includes a stirring motor 71, a material cylinder 72, a feeding hopper 73, a feeding pipe 74, a feeding valve 75, and a pneumatic controller 76. The material cylinder 72 is installed on the top of the turntable 30. The pneumatic controller 76 is installed on the side wall of the material cylinder 72. The stirring motor 71 is installed on the top of the material cylinder 72, and a discharge port 721 is provided at the bottom. A hydraulic sensor is provided at the discharge port 721, and the hydraulic sensor is electrically connected to the pneumatic controller 76. A feeding pipe 74 is provided on the side wall of the material cylinder 72, a feeding hopper 73 is provided at the end of the feeding pipe 74, and a feeding valve 75 is installed on the feeding pipe 74.

[0057] It should be noted that since the feed pipes of each of the nozzles 80 are directly connected to the discharge port 721 of the feeding mechanism 70, the hydraulic pressure and flow rate at the outlet of each of the nozzles 80 will be the same. As a result, the thickness and density of the material sprayed by each of the nozzles 80 can be ensured to be the same, making the glaze surface uniform. And since the hydraulic pressure at the discharge port of the feeding mechanism 70 remains constant, during the entire glazing process, it can be ensured that the glaze on the entire glazing surface of the ceramic sanitary ware 90 is uniform and stable. The constancy of the hydraulic pressure at the discharge port of the feeding mechanism 70 is controlled by a hydraulic sensor and a pneumatic controller 76. During the glazing process, the material cylinder 72 will gradually decrease. Usually, the hydraulic pressure at the discharge port 721 will also gradually decrease. To keep the hydraulic pressure at the discharge port 721 constant, in this embodiment, the hydraulic sensor is used to monitor the hydraulic pressure at the discharge port 721 in real time, and then the measured hydraulic data is sent to the pneumatic controller 76. The pneumatic controller 76 fills the upper part inside the material cylinder 72 with gas for pressure compensation according to the real-time discharge port hydraulic pressure, so as to ensure the constancy of the hydraulic pressure at the discharge port 721.

[0058] The feeding mechanism 70 of this embodiment is installed on the turntable 30 and can move with the turntable. Therefore, during the rotation of the turntable 30, the problem of the feed pipe winding can be avoided.

[0059] The working principle of the embodiment of the present invention: First, turn on the first driving motor 41 to control the nozzle 80 to move above the glazing area; then turn off the first driving motor 41 and turn on the three synchronously working rotating motors 51 to control the discharge port of the nozzle 80 to face the glazing area; then turn off the rotating motors 51 and turn on the main motor 11 to control the nozzle 80 to move to a preset distance from the glazing area; finally, turn off the main motor 11 and turn on the second driving motor 61 to control the nozzle 80 to rotate around the center of the positioning cylinder 20. After the rotation is stable (i.e., after a preset time), open the discharge valve at the discharge port 721, and the nozzle 80 will perform rotary spraying on the glazing area of the ceramic sanitary ware 90. After rotating one week, sequentially close the discharge valve at the discharge port 721 and the second driving motor 61. The glazing work of the glazing area is completed, and then perform the above operations in sequence to perform the glazing work on the next glazing area.

[0060] The glaze spraying device for ceramic sanitary ware of the present invention has a nozzle for spraying glaze connected to the end of the rocker 45 of the horizontal displacement adjusting mechanism 40. Therefore, the horizontal displacement of the nozzle 80 can be adjusted by the horizontal displacement adjusting mechanism 40 to achieve the control of the horizontal position of the nozzle 80 when the nozzle 80 moves from the outer circle to the inner circle of the glaze spraying surface of the ceramic sanitary ware 90. Moreover, three or more nozzles 80 can be synchronously controlled through the inclined arc grooves arranged in a circumferential array on the turntable 30 to achieve efficient glaze spraying on each glaze spraying area of the ceramic sanitary ware 90 for multiple repetitions.
