Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ceramic glazing, in particular to a ceramic glazing device. BACKGROUND

[0002] Ceramic products can be divided into three categories: pottery, stoneware and porcelain according to the material of the body, collectively known as "ceramics". No matter what kind of category, glazing is an indispensable process before ceramic firing; the quality of the glaze layer directly determines the appearance, strength and later use performance of the product. Therefore, the quality of the finished ceramic product depends not only on the selection of raw materials, the shaping of the body and the control of the firing system, but also to a large extent on the stability and uniformity of the glazing process of the blank.

[0003] At present, domestic ceramic production enterprises generally use the traditional manual glazing method when glazing round blanks: the ceramic blank to be glazed is placed on a rotatable support, and the worker holds a spray gun to complete the uniform spraying of the glaze slurry during the rotation of the blank according to personal experience.

[0004] With the development of ceramic products towards "large size, thin wall and complexity", the disadvantages of manual glazing are becoming more and more prominent: on the one hand, it takes a long time to train skilled glazing workers and the labor cost is high; on the other hand, in mass production, workers are prone to fatigue after long-time repetitive work, which leads to uneven glaze thickness, pinholes, glaze flow and other defects, and the production efficiency and product yield are significantly restricted.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1.

[0017] 2. This invention utilizes the upper and lower tracks of the limiting groove and the limiting rod to enable automatic "disengagement-engagement" of the spline: when the limiting rod enters the lower half of the limiting groove, the protrusion engages with the stop block in the lower clearance groove, and the placement platform rotates; when the limiting rod enters the upper half of the limiting groove, the protrusion slides into the upper clearance groove, the spline spins freely, and the placement platform stops rotating. This "one-click disengagement-engagement" requires no additional power and can quickly switch between the glazing station and the loading / unloading station, solving the pain points of "long changeover and debugging time and slow cycle time for small batch production".

[0018] 3. This invention uses a cam to drive a connecting rod to drive the nozzle to reciprocate up and down, and combines a transmission component and an angle adjustment component to achieve adaptive adjustment of the nozzle's pitch angle, ensuring that the glaze is sprayed onto the blank surface at near-vertical speed in real time, thereby improving the glaze quality.

[0019] 4. In the glazing process, the outer diameter of the sample blank changes through the linkage of the first moving rod and the second moving rod, which automatically adjusts the distance between the nozzle and the blank surface, keeps the spacing constant, avoids uneven glaze thickness caused by distance changes, and significantly improves the uniformity of the glaze layer.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1-14 As shown, the present invention has the following four specific embodiments.

[0024] Example 1

[0025] A ceramic glazing device includes a base 1, a partition 11 fixedly connected to the inner wall of the base 1, a limiting groove 13 formed on the inner wall of the base 1 above the partition 11, a bracket 12 fixedly connected to the left outer wall of the base 1, a rotating seat 2 rotatably connected to the upper end of the base 1, a fixing rod 22 fixedly connected to the lower end of the rotating seat 2, a rotating disk 23 fixedly connected to the lower end of the fixing rod 22, and the side wall of the rotating disk 23 rotatably connected to the inner wall of the base 1; and further includes: Placement mechanism 3, which consists of four sets and is installed at equal intervals inside the rotating seat 2, is used to place ceramic blanks; Drive mechanism 4 is installed on the upper end of partition 11 and is used to drive the placement mechanism 3 and the rotating seat 2 to rotate. Replaceable limit mechanism 5 is installed on the upper left side of bracket 12; The glazing mechanism 7 is mounted on the upper end of the bracket 12. It includes a pair of second guide rods 71. A second lifting plate 72 is slidably connected between the side walls of the pair of second guide rods 71. A limit seat 721 is symmetrically fixed to the upper end of the second lifting plate 72. A first moving rod 73 and a second moving rod 74 are slidably connected inside the second moving rod 721. The opposite end faces of the two rods are provided with toothed grooves 79. An installation cavity 722 is provided inside the limit seat 721. A fourth gear 78 is rotatably connected inside the installation cavity 722. The fourth gear 78 meshes with the two sets of toothed grooves 79 respectively. A nozzle 76 is provided between the pair of second moving rods 74. A transmission component 75 is provided between the first moving rod 73 and the second moving rod 74. An angle adjustment component 77 is provided on the first moving rod 73 for adjusting the pitch angle of the nozzle 76. Transmission mechanism 6 is installed inside the base 1 and is used to transmit the motion of drive mechanism 4 to glazing mechanism 7. The replaceable limiting mechanism 5 includes a bolt 51, with a support frame 53 fixedly connected to the upper end of the bolt 51. The lower end of the support frame 53 abuts against the upper end of the bracket 12. A sample blank 54 is fixedly connected to the upper end of the support frame 53. The sample blank 54 is made of metal material. The lower end of the bolt 51 extends to the lower end of the bracket 12. A nut 52 is threadedly connected to the side wall of the bolt 51 located at the lower end of the bracket 12. The upper end of the nut 52 abuts against the lower end of the bracket 12.

[0026] In this embodiment, as Figures 1-2 , Figure 10 As shown, the ceramic blank is first placed above the right-side placement mechanism 3; then, the drive mechanism 4 is activated, smoothly moving the placement mechanism 3 carrying the ceramic blank to the right side of the glazing mechanism 7. Driven by the drive mechanism 4, the placement mechanism 3 begins to rotate, thereby causing the ceramic blank to rotate synchronously, providing uniform glazing conditions for the glazing mechanism 7; While the drive mechanism 4 is running, the glazing mechanism 7 achieves reciprocating motion up and down through the linkage of the transmission mechanism 6. The glazing mechanism 7 adjusts the pitch angle of the nozzle 76 in real time according to the changes in the outer contour of the ceramic blank, ensuring that the spraying direction is close to perpendicular to the blank surface in real time, and keeping the distance between the nozzle 76 and the ceramic blank constant, thereby achieving a uniform and high-quality glazing effect; After the glazing process is completed, the ceramic blank is moved to the unloading station by the placement mechanism 3. The operator can easily remove the glazed ceramic blank and replace it with a new ceramic blank to be glazed. If ceramic blanks of different sizes or shapes need to be glazed, the operator only needs to loosen the fixing nut 52 to completely disassemble the support frame 53 and the sample blank 54, and quickly replace it with a new sample blank 54 that matches the shape of the ceramic blank to be glazed, thus achieving efficient and flexible glazing operations.

[0027] Example 2

[0028] The difference from Embodiment 1 is that this embodiment discloses the specific structure of the placement mechanism 3; An isolation seat 21 is fixedly connected to the upper end of the rotating seat 2. The isolation seat 21 is used to isolate the placement mechanism 3. The placement mechanism 3 includes a spline sleeve 31, which is rotatably connected to the inside of the rotating disk 23. A first gear 32 is fixedly connected to the lower side wall of the spline sleeve 31. A spline 33 is slidably connected to the upper side of the spline sleeve 31. An installation groove 331 is provided on the side wall of the spline 33. A first spring 34 is fixedly connected to the inside of the installation groove 331. A protrusion 35 is fixedly connected to the end of the first spring 34. The protrusion 35 is located inside the installation groove 331 and is slidably connected thereto. The end of the protrusion 35 extends through to the outside of the spline 33. A first lifting plate 38 is rotatably connected to the side wall of the spline 33. A first guide rod 39 is slidably connected inside the first lifting plate 38. The upper end of the first guide rod 39 is fixedly connected to the lower end of the rotating seat 2. The lower end of the first guide rod 39 is fixedly connected to the upper end of the rotating disk 23. A limit rod 381 is fixedly connected to the end of the first lifting plate 38. The end of the limit rod 381 is located inside the limit groove 13 and is slidably connected thereto. The placement mechanism 3 also includes a sleeve 36, which is rotatably connected inside the rotating seat 2 and located directly above the spline sleeve 31. A pair of clearance grooves 361 are opened on the inner wall of the sleeve 36. A stop block 362 is fixedly connected inside the clearance groove 361 on the lower side of the sleeve 36. The upper end of the spline 33 extends through the inside of the sleeve 36. The end of the protrusion 35 is located inside the clearance groove 361. The upper end of the sleeve 36 is fixedly connected to the placement platform 37 for supporting the ceramic blank.

[0029] In this embodiment, as Figures 6-8As shown, after the rotating seat 2 steps into position, the limiting rod 381 slides up and down along the trajectory of the limiting groove 13. When sliding down, the first lifting plate 38 slides down on the side wall of the first guide rod 39, the spline 33 moves down synchronously, the protrusion 35 moves into the lower clearance groove 361, and the protrusion 35 is blocked by the stop block 362. When the first gear 32 rotates, the spline sleeve 31 rotates, so the sleeve 36 rotates with the spline 33, driving the ceramic blank to rotate. When sliding up, the protrusion 35 disengages from the stop block 362 and pops out under the action of the first spring 34, and slides into the upper clearance groove 361. The spline 33 rotates inside the sleeve 36, the sleeve 36 and the ceramic blank stop rotating, and only revolve with the rotating seat 2, realizing the "lift-disengage, lower-engage" unpowered clutch, ensuring that the ceramic blank in the glazing station rotates, while the ceramic blanks in other stations remain stationary, completing efficient switching and uniform glazing.

[0030] Example 3

[0031] The difference from Embodiment 2 is that this embodiment discloses the specific structure of the drive mechanism 4; The drive mechanism 4 includes a first transmission rod 42 and a rotating rod 46. The first transmission rod 42 is rotatably connected to the upper end of the partition plate 11. A second gear 43 and a third gear 45 are fixedly connected to the side wall of the first transmission rod 42. The second gear 43 is located below the third gear 45. A gear ring 44 is rotatably connected inside the base 1. The second gear 43 meshes with the lower inner wall of the gear ring 44, and the upper inner wall of the gear ring 44 meshes with the first gear 32. The rotating rod 46 is rotatably connected to the upper end of the partition plate 11. A dial 47 is fixedly connected to the side wall of the rotating rod 46. A grooved wheel 48 is fixedly connected to the lower middle part of the rotating disk 23. The dial 47 and the grooved wheel 48 are intermittently meshed with each other through a cylindrical pin and a radial groove to achieve unidirectional intermittent rotation of the grooved wheel 48. Teeth are fixedly connected at equal intervals on the side wall of the dial 47, and the teeth mesh with the third gear 45. The drive mechanism 4 also includes a motor 41, which is fixedly connected to the lower end of the partition 11, and the output shaft end of the motor 41 is fixedly connected to the lower end of the first transmission rod 42.

[0032] In this embodiment, as Figures 3-5 As shown, the motor 41 starts its output shaft to drive the first transmission rod 42 to rotate continuously. The second gear 43 fixed on it drives the gear ring 44 to rotate. The gear ring 44 then meshes with the four first gears 32 at the same time, so that all the placement mechanisms 3 in the engagement state rotate synchronously. At the same time, the third gear 45 rotates with the first transmission rod 42, and drives the dial 47 to rotate continuously through the teeth. Each time the cylindrical pin on the dial 47 is inserted into the radial groove of the grooved wheel 48, it pushes the grooved wheel 48 to rotate 90°, so that the rotating seat 2 completes one step, realizing the compound motion of "non-stop rotation and intermittent revolution", thereby accurately sending the ceramic blank to the feeding, glazing and unloading stations in sequence. The entire drive chain is completed by only one input shaft to complete multiple action outputs. It has a compact structure, low energy consumption and simple maintenance.

[0033] Example 4

[0034] The difference from Embodiment 3 is that this embodiment discloses the specific structures of the transmission mechanism 6 and the glazing mechanism 7; The transmission mechanism 6 includes a second transmission rod 62, which is rotatably connected to the inner wall of the base 1.

The left end of the second transmission rod 62 is fixedly connected to a cam 64. The left end of the protrusion of the cam 64 is rotatably connected to a connecting rod 65 through a pin. The upper end of the connecting rod 65 extends upward and is hinged to the glazing mechanism 7. A dust cover 66 is fixedly connected to the outer left side of the base 1, and the upper end of the dust cover 66 is fixedly connected to the lower end of the bracket 12. A pair of second guide rods 71 ​​are symmetrically fixedly connected to the front and rear sides of the upper end of the bracket 12. The lower end of the second lifting plate 72 is hinged to the upper end of the connecting rod 65. The first moving rod 73 is located below the second moving rod 74. The left end of the first moving rod 73 extends through to the outside of the limiting seat 721. A first connecting rod 732 is fixedly connected between the pair of first moving rods 73. A second spring 731 is fixedly connected to the end of the first connecting rod 732 near the second lifting plate 72. The end of the second spring 731 away from the first connecting rod 732 is fixedly connected to the left end of the second lifting plate 72. The right end of the second moving rod 74 extends through to the right side of the limiting seat 721. A second connecting rod 741 is fixedly connected between the pair of second moving rods 74. A first rotating rod 742 is rotatably connected between the pair of second moving rods 74. A first fixing block 743 is fixedly connected to the side wall of the first rotating rod 742. A nozzle 76 is fixedly connected to the right end of the first fixing block 743. The transmission assembly 75 includes a plug rod 751, which is rotatably connected to the side wall of the second moving rod 74 at the front side via a bearing seat. A third bevel gear 752 is fixedly connected to the right end of the plug rod 751. A fourth bevel gear 753 meshes with the side wall of the third bevel gear 752. The fourth bevel gear 753 is fixedly connected to the front end of the first rotating rod 742. A sleeve rod 754 is slidably sleeved on the left side wall of the plug rod 751. The outer wall of the sleeve rod 754 is rotatably connected to the side wall of the first moving rod 73 at the front side via a bearing seat. A fifth bevel gear 755 is fixedly connected to the left end of the sleeve rod 754. The angle adjustment assembly 77 includes a second rotating rod 771, which is rotatably connected between a pair of first moving rods 73. A sixth bevel gear 775 is fixedly connected to the front end of the second rotating rod 771. The sixth bevel gear 775 meshes with the fifth bevel gear 755. A second fixing block 772 is fixedly connected to the side wall of the second rotating rod 771. A top rod 773 is fixedly connected to both the upper and lower ends of the second fixing block 772. A groove 7731 is provided on the left end face of the top rod 773. A ball bearing 774 is embedded in the groove 7731. The left side of the ball bearing 774 maintains rolling contact with the side wall of the sample blank 54.

[0035] In this embodiment, as Figure 3 , Figures 9-14 As shown, the power of the rotating rod 46 is reversed through the first bevel gear 61 and the second bevel gear 63, and the second transmission rod 62 drives the cam 64 to rotate. The cam 64 converts the continuous rotation into the reciprocating motion of the second lifting plate 72 along the second guide rod 71 through the connecting rod 65. During the lifting process, the first moving rod 73 and the second moving rod 74 slide in opposite directions in equal amounts due to the linkage of the tooth groove 79 and the fourth gear 78, so that the distance between the nozzle 76 and the blank surface remains constant. Since the ball bearing 774 is always in contact with the sample blank 54, when the second lifting plate 72 moves upward, the outer diameter of the sample blank 54 is different from bottom to top, which will drive the second rotating rod 771 to rotate. The second rotating rod 771 rotates, driving the sixth bevel gear 775 to rotate. The sixth bevel gear 775 rotates, driving the fifth bevel gear 755 to rotate. The fifth bevel gear 755 rotates, driving the sleeve rod 754 to rotate. The sleeve rod 754 rotates, driving the insert rod 751 to rotate. The insert rod 751 rotates, driving the third bevel gear 752 to rotate. The third bevel gear 752 rotates, driving the first rotating rod 742 to rotate, thereby driving the first fixed block 743 to rotate. This, in turn, drives the nozzle 76 to adjust its angle, allowing the nozzle 76 to adjust its pitch angle. The spray direction approaches vertical spraying onto the ceramic blank surface in real time, adaptively adjusting according to the contour of the ceramic blank to achieve uniform glazing.

[0036] The working principle of this invention is as follows: After the motor 41 starts, its output shaft drives the first transmission rod 42 to rotate continuously. The second gear 43, which is fixed on the first transmission rod 42, drives the gear ring 44 to rotate. The gear ring 44 meshes with the four first gears 32 at the same time, thereby driving the spline sleeve 31 to rotate. At the same time, the third gear 45 rotates with the first transmission rod 42, and drives the dial 47 to rotate continuously through its teeth. Each time the cylindrical pin on the dial 47 is inserted into the radial groove of the grooved wheel 48, it pushes the grooved wheel 48 to rotate 90°, so that the rotating seat 2 completes one step, thereby realizing the precise sequential delivery of the ceramic blank to the feeding, glazing, and unloading stations. When the rotating seat 2 steps into position, the limiting rod 381 slides up and down along the trajectory of the limiting groove 13: when sliding down, the first lifting plate 38 moves down along the first guide rod 39, the spline 33 moves down synchronously, the protrusion 35 enters the lower clearance groove 361 and is blocked by the stop block 362, and the spline 33 drives the sleeve 36 and the ceramic blank to rotate through the spline sleeve 31; when sliding up, the protrusion 35 disengages from the stop block 362 and pops out under the action of the first spring 34, slides into the upper clearance groove 361, the spline 33 spins freely in the sleeve 36, the sleeve 36 and the ceramic blank stop rotating, and only revolve with the rotating seat 2, realizing the "lift-disengage, lower-engage" non-powered clutch, ensuring that the ceramic blank of the glazing station rotates while the other stations remain stationary. At the glazing station, the power of the rotating rod 46 is reversed through the first bevel gear 61 and the second bevel gear 63, and the second transmission rod 62 drives the cam 64 to rotate. The cam 64 converts the continuous rotation into the reciprocating motion of the second lifting plate 72 along the second guide rod 71 through the connecting rod 65. During the lifting process, the first moving rod 73 and the second moving rod 74 slide in opposite directions in equal amounts due to the linkage of the tooth groove 79 and the fourth gear 78, so that the distance between the nozzle 76 and the blank surface remains constant. Simultaneously, under the elastic thrust of the second spring 731, the first moving rod 73 drives the angle adjustment component 77 to move closer to the sample blank 54, ensuring that the ball bearing 774 remains in rolling contact with the side wall of the sample blank 54. When the second lifting plate 72 moves up and down, the change in the outer diameter of the sample blank 54 drives the second rotating rod 771 to rotate. This rotation is transmitted to the first rotating rod 742 via the sixth bevel gear 775, the fifth bevel gear 755, the sleeve rod 754, the insertion rod 751, the third bevel gear 752, and the fourth bevel gear 753, driving the nozzle 76 to adjust its pitch in real time, so that the spraying direction approaches vertical spraying onto the blank surface, achieving uniform glazing. After glazing is completed, the rotating seat 2 steps forward again, moving the glazed ceramic blank to the unloading station. The operator removes the finished product and replaces it with a new ceramic blank. The entire cycle is driven by a single motor 41, achieving efficient coordination of loading, rotation, glazing, and unloading.
