Description

Technical Field

[0001] The present invention relates to the field of ceramic glazing, and specifically to a glazing device and a usage method for ceramic production. Background Art

[0002] The traditional concept of ceramics refers to all artificial industrial products made from inorganic non-metallic minerals such as clay; it includes various products made by mixing, shaping, and calcining clay or mixtures containing clay; all products from the roughest earthenware to the finest fine pottery and porcelain belong to its scope; its main raw materials are taken from natural silicate minerals such as clay, quartz, etc., so it belongs to the category of "silicate industry" together with industries such as glass, cement, enamel, and refractory materials. Currently, during the ceramic production process, it is necessary to glaze the surface of ceramics.

[0003] The existing patent CN111906909B discloses a glazing device and method for ceramic bottle blanks. There is a glazing bucket, and a first motor is fixedly connected to the center inside the glazing bucket. The first motor extends upward with a motor shaft, and a rotating platform is fixedly connected to the upper end of the motor shaft. A support plate is arranged at the upper end of the rotating platform, and a ceramic blank is placed in the middle of the upper end of the support plate. A conveying pipe is fixedly connected to the side wall of the glazing bucket, and spray heads are fixedly connected to the side wall of the conveying pipe at equal distances. Through the spraying method, the one-time slurry preparation amount can be greatly reduced. At the same time, by using the centrifugal method, the excess slurry on the ceramic blank can be thrown out to ensure the uniformity of slurry coating.

[0004] During the implementation of this solution, the following problems in the prior art were found not to be well solved: 1. In the process of spraying glaze on porcelain bottles in the above solution, since the ports of the porcelain bottles cannot be closed, there will be a situation where the glaze flows into the interior of the ceramic blank, and the glaze will be sprayed on the inner side of the curved ceramic blank, resulting in rough interiors after firing and affecting the final quality of the ceramics.

[0005] 2. The above-mentioned prior art glazing device can only glaze single ceramics, and the operator needs to replace the ceramics back and forth. When replacing the glazed ceramics, the glazing device is in an idle state, reducing the glazing efficiency, slow glazing speed, and being time-consuming and laborious. Summary of the Invention

[0015] A usage method of a glazing device for ceramic production includes the following steps:

[0016] S1. First, fix the ceramic blank on the conveyor belt. When the moving block approaches the conveyor belt, at this time, the guide pin is located on one side of the guide groove. During the rotation of the guide pin driven by the first hinge rod, the guide pin moves vertically downward along the guide of the guide groove. At this time, the guide pin drives the moving block to move vertically downward, so that the L-shaped pressing rod on the moving block drives the air cylinder to descend. When the air cylinder descends to the bottle mouth of the ceramic blank, the bottom of the air cylinder presses on the top position of the ceramic blank to limit its movement. By the continuous descent of the L-shaped pressing rod, the L-shaped pressing rod drives the piston disc fixed on the surface to move downward, so that the air bag at the bottom of the L-shaped pressing rod moves into the inside of the bottle mouth of the ceramic blank. And during the downward movement of the piston disc, the piston disc squeezes the gas inside the lower end of the air cylinder, so that the gas enters the air bag through the telescopic hose, and the air bag begins to expand, sealing the bottle mouth of the ceramic blank and tightening the bottle mouth. When the moving block drives the tightening assembly to descend to clamp and fix the bottle mouth of the ceramic blank, the pressing block at the lower end of the moving block presses on one end of the limit rod, causing the limit rod to flip. At this time, the limit rod releases the shielding of the ceramic blank, so as to facilitate the moving block to drive the clamped ceramic blank to move horizontally. At the same time, the moving block drives the annular spraying pipe on the air cylinder and the annular spraying pipe on the moving plate to move.

[0017] S2. Then, the first hinge rod slidably installed on the fixed sleeve drives the guide pin to move horizontally on the guide groove, so that the guide pin drives the moving block and the moving plate to move horizontally. At this time, the moving block moves away from the first pressing rod, and the first spring elastically resets. The second hinge rod hinged at the bottom of the first pressing rod pulls the hinged rack to move, shielding the corresponding ceramic blank, while the other rack moves and contracts, moving the ceramic blank to one end of the conveyor belt, facilitating the next glazing operation. Repeating this way realizes the intermittent conveying of the ceramic blank.

[0018] S3. During the movement of the annular spraying pipes on the air cylinder and the moving plate, when the guide pin on the moving block moves to the lower part of the guide groove, the bottoms of the second pressing rods at one ends of the two annular spraying pipes press on the top of the trapezoidal pressing strip on the inner wall of the box body, so that the second pressing rod pushes the movable block to move upward above the connecting box. At this time, the through hole is communicated with the annular spraying pipe and the material guiding pipe, and the glaze liquid is sprayed out from the upper and lower two annular spraying pipes to glaze the outer wall of the ceramic blank.

[0019] S4. After the glazed porcelain blank moves horizontally into place, the bottom of the second pressing rod releases the extrusion of the corresponding trapezoidal pressing strip. Driven by the elastic reset of the second spring, the second pressing rod drives the movable block to move downward, so that the movable block blocks the glaze liquid, stopping the glazing. And when the tightening assembly drives the porcelain blank to move towards the clamping plate position, the pushing blocks fixed on both sides of the upper annular spraying pipe squeeze against the corresponding L-shaped movable rods through the trapezoidal side walls, causing the two symmetric L-shaped movable rods on the U-shaped plate to move in opposite directions at the same time, and the two clamping plates are in an open state. After the porcelain blank on the tightening assembly moves between the two clamping plates, the L-shaped movable rod releases the pressing against the trapezoidal inclined surface of the side wall of the pushing block, and the L-shaped movable rod is elastically reset through the second return spring, so that the two clamping plates fix the glazed porcelain blank.

[0020] S5. Then the guide pin moves vertically upward again along the guidance of the guide groove, so that the guide pin drives the movable block to move vertically upward. When the movable block moves vertically upward, since the porcelain blank is in a clamped and fixed state, the L-shaped pressing rod drives the piston disc fixed on the surface to move upward. At this time, the gas inside the airbag enters the lower end of the air cylinder through the telescopic hose, and the airbag shrinks, releasing the tightening and fixing of the bottle mouth, so that the airbag automatically detaches from the bottle mouth. After the movable block drives the airbag to move upward in place, the guide pin drives the movable block and the movable plate to move horizontally for reset, and performs the glazing operation on the next porcelain blank.

[0021] S6. When the L-shaped pressing rod moves upward, the top of the L-shaped pressing rod will squeeze against the bottom of the movable frame, thereby driving the movable frame to rise, so that the movable frame drives the fixed movable sleeve to move upward. At this time, the limit pin on the inner wall of the movable sleeve slides towards the arc-shaped groove on the limit groove. Through the vertical upward movement of the limit pin, the connecting column drives the turntable to rotate along the arc-shaped groove position. When the limit pin moves upward in place, the connecting column drives the turntable to complete a 90-degree rotation, so as to automatically perform position conversion on the clamped porcelain blank. And when the L-shaped pressing rod moves horizontally after moving vertically upward in place, the L-shaped pressing rod releases the extrusion of the movable frame. At this time, the movable sleeve is elastically reset through the third return spring, pushing the movable sleeve to move downward, so that the limit pin on the inner wall of the movable sleeve moves downward along the vertical groove on the limit groove to complete the reset.

[0022] S7. While the connecting column drives the turntable to rotate, the mounting block on the turntable rotates, so that the bevel gear shaft rotatably installed inside the mounting block meshes with the arc-shaped rack at the bottom of the connecting sleeve fixedly installed on the box body, so that the bevel gear shaft drives the U-shaped plate to flip 180 degrees. At this time, after flipping 180 degrees, the glaze on the porcelain blank flows in the reverse direction, and after the U-shaped plate completes a 180-degree flip, the main magnet block attracts the corresponding secondary magnet block, restricting the shaking of the U-shaped plate.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] In the present invention, through the arrangement of components such as a tightening component, a conveying mechanism, and a liquid discharging component, it is possible to automatically seal the mouth of the glazed porcelain blank, prevent the glaze from flowing into the interior of the ceramic blank, which affects the final quality of the ceramic, drive the porcelain blank to move, spray the porcelain blank up and down with a ring-shaped spraying pipe, and perform automatic glazing. Through the collision and dispersion of the glaze in the up and down directions, the contact time between the glaze and the porcelain blank is further extended, and the glazing effect is improved.

[0025] In the present invention, through the arrangement of components such as a clamping component, a flipping component, and a rotating component, when the moving block drives the tightening component to move upward, the turntable automatically rotates 90 degrees, thereby realizing the position conversion of the clamped porcelain blank, and at the same time flipping the clamped porcelain blank 180 degrees. At this time, after flipping 180 degrees, the glaze on the porcelain blank flows reversely, further improving the glazing effect of the porcelain blank.

[0026] In the present invention, through the arrangement of the shielding component, the porcelain blanks on the conveyor belt can be intermittently conveyed below the tightening component, thereby further improving the working efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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.

[0043] Please refer to Figures 1 to 14 , the present invention provides a technical solution: a glazing device for ceramic production, including a box body 1 and a conveyor belt 2. The conveyor belt 2 is arranged on one side of the box body 1. A conveying mechanism 3 for conveying ceramic blanks is arranged on the box body 1, and a shielding component 4 is arranged on one side of the box body 1;

[0044] The conveying mechanism 3 includes: a motor 301 fixedly installed on the box body 1; a gear 302 fixedly connected to the output end of the motor 301; a first gear shaft 303 meshing with the gear 302. Here, it should be noted that the diameter of the first gear shaft 303 is larger than that of the gear 302, similar to a reduction gear set. During the rotation of the gear 302, the first gear shaft 303 can rotate slowly, and the first gear shaft 303 is rotatably installed on the box body 1; a fixed sleeve 304 fixedly installed at the end of the first gear shaft 303; a first hinge rod 305 slidably penetrating through the fixed sleeve 304. Here, it should be added that a plurality of balls are equidistantly arranged along the circumference on the inner wall of the fixed sleeve 304, and the surface of the balls is placed on the outer wall of the first hinge rod 305 to reduce the friction between the first hinge rod 305 and the inner wall of the fixed sleeve 304 during swinging and reduce the interference problem between the two; a guide pin 306 rotatably installed at the end of the first hinge rod 305; a moving block 307 fixedly installed at one end of the guide pin 306; a guide groove 308 opened on the inner wall of the box body 1. Here, it should be noted that the guide groove 308 is rectangularly arranged, and an arc chamfer is provided at the corner so that the guide pin 306 can drive the moving block 307 to move in a rectangular manner on the guide groove 308. The other end of the guide pin 306 is rotatably installed inside the guide groove 308; a moving plate 6 slidably installed at the lower end of the moving block 307. Here, it should be added that a fixed rod is fixedly installed on the moving plate 6, and the bottom of the moving block 307 is slidably installed up and down on the fixed rod. On the one hand, the moving block 307 can drive the moving plate 6 to move, and on the other hand, to a certain extent, the moving plate 6 enables the guide pin 306 on the moving block 307 to move in the track of the guide groove 308 without detachment; a first guide rod 601 for guiding the movement of the moving plate 6, and both ends of the first guide rod 601 are fixedly installed inside the box body 1; and a tightening component 5 arranged on the moving block 307 for fixing the conveyed ceramic blanks; a limiting component 9 is also arranged between the moving block 307 and one end of the conveyor belt 2;

[0045] During the transportation of the clamped porcelain embryo, the output end of the motor 301 drives the gear 302 to mesh and rotate with the first gear shaft 303, causing the fixed sleeve 304 fixed on the first gear shaft 303 to drive the first hinge rod 305 slidably installed inside it to rotate along the axis of the first gear shaft 303. At this time, the guide pin 306 sleeved at the driving end of the first hinge rod 305 rotates. Since the guide pin 306 is fixedly connected to the moving block 307, and the bottom of the moving block 307 is slidably installed up and down with the moving plate 6, the rolling of the guide pin 306 in the guide groove 308 can be restricted. When the guide pin 306 moves along the track inside the guide groove 308, it drives the moving block 307 to move in a rectangular manner.

[0046] The shielding assembly 4 includes: a bracket 401 fixedly installed on one side of the box body 1; racks 402 symmetrically and slidably installed on the bracket 401; a second gear shaft 403 meshing with the racks 402, and the bottom of the second gear shaft 403 is rotatably installed on the bracket 401; a second hinge rod 404 hingedly installed at the end of a set of racks 402; a first pressing rod 405 penetrating through one side of the box body 1, and the bottom of one end of the first pressing rod 405 is hingedly installed with one end of the second hinge rod 404; a first spring 406 sleeved on the other end of the first pressing rod 405, and one end of the first spring 406 is fixedly connected to the surface of the other end of the first pressing rod 405, and the other end of the first spring 406 is fixedly connected to the inner wall of the box body 1.

[0047] When the tightening assembly 5 on the moving block 307 moves back to the position of the conveyor belt 2, when the moving block 307 moves closer to the position of the shielding assembly 4, the side wall of the moving block 307 presses on the first pressing rod 405, causing the first pressing rod 405 to drive the hinged second hinge rod 404 to deflect. At this time, the second hinge rod 404 pushes the hinged rack 402 to move, causing the rack 402 to mesh with the second gear shaft 403. At this time, the second gear shaft 403 drives another meshing rack 402 to mesh, so that the rack 402 shields the porcelain embryo conveyed on the conveyor belt 2. When the tightening assembly 5 completes the clamping and conveying of the porcelain embryo, the moving block 307 moves away from the first pressing rod 405. At this time, the first spring 406 elastically resets, and the second hinge rod 404 hinged at the bottom of the first pressing rod 405 pulls the hinged rack 402 to move again to shield the corresponding porcelain embryo, while the other rack 402 moves and contracts, causing the porcelain embryo to move to one end of the conveyor belt 2, facilitating the next glazing operation. In this way, the intermittent conveying of the porcelain embryo is realized repeatedly, improving the work efficiency.

[0048] In this embodiment, as Figures 1 to 14As shown in the figure, the tightening assembly 5 includes an L-shaped pressing rod 501 fixedly installed on the moving block 307. It should be noted here that the diameter of the L-shaped pressing rod 501 above the air cylinder 502 is larger than the diameter of the top opening of the air cylinder 502. After the L-shaped pressing rod 501 moves down in place, the L-shaped pressing rod 501 will restrict the upward movement of the air cylinder 502 to prevent the gas in the airbag 506 from flowing back into the air cylinder 502; the air cylinder 502 movably installed on the L-shaped pressing rod 501; the piston disk 503 fixedly installed on the L-shaped pressing rod 501, and the side wall of the piston disk 503 fits against the inner wall of the air cylinder 502; the telescopic spring 504 sleeved on the lower end of the L-shaped pressing rod 501. After the glazed porcelain embryo is clamped by the clamping plate 1106, when the L-shaped pressing rod 501 rises, the gas in the airbag 506 is transported into the air cylinder 502, reducing the volume of the airbag 506, releasing the tightening of the mouth of the porcelain embryo, and through the setting of the telescopic spring 504, pushing the air cylinder 502 to quickly reset, accelerating the entry of the gas inside the airbag 506 into the air cylinder 502, which helps to increase the separation speed between the airbag 506 and the porcelain embryo bottle mouth. One end of the telescopic spring 504 is fixedly connected to the bottom of the piston disk 503, and the other end of the telescopic spring 504 is fixedly connected to the bottom wall of the air cylinder 502; the telescopic hoses 505 symmetrically and fixedly connected to the bottom of the air cylinder 502; the airbag 506 fixedly connected between the two telescopic hoses 505; and the annular spray pipes 7 respectively fixedly installed on the air cylinder 502 and the moving plate 6, and the two annular spray pipes 7 are vertically centered. There is a liquid outlet assembly 8 between one end of the annular spray pipe 7 and the inner wall of the box body 1. There is a turntable 10 on the other side of the box body 1, and four clamping assemblies 11 are equidistantly arranged along the circumference on the turntable 10.

[0049] When the moving block 307 approaches the conveyor belt 2, at this time the guide pin 306 is located on one side of the guide groove 308. During the rotation of the guide pin 306 driven by the first hinge rod 305, the guide pin 306 vertically moves downward along the guidance of the guide groove 308. At this time, the guide pin 306 drives the moving block 307 to move vertically downward, so that the L-shaped pressing rod 501 on the moving block 307 drives the air cylinder 502 to descend. When the air cylinder 502 descends to the bottle mouth of the porcelain embryo, the bottom of the air cylinder 502 presses against the top position of the porcelain embryo to restrict its movement. Through the continuous descent of the L-shaped pressing rod 501, the L-shaped pressing rod 501 drives the piston disk 503 fixed on its surface to move downward, so that the airbag 506 at the bottom of the L-shaped pressing rod 501 moves into the inside of the bottle mouth of the porcelain embryo. And during the downward movement of the piston disk 503, the piston disk 503 squeezes the gas inside the lower end of the air cylinder 502, so that the gas enters the airbag 506 through the telescopic hose 505, and the airbag 506 begins to expand, sealing the bottle mouth of the porcelain embryo and tightening and fixing the bottle mouth.

[0050] In this embodiment, as Figures 1 to 14As shown in the figure, the liquid outlet assembly 8 includes a connection box 801 fixedly installed at one end of the annular spraying pipe 7; a material guiding pipe 802 communicated with the inside of the connection box 801, and the material guiding pipe 802 is slidably installed on the box body 1. The material guiding pipe 802 is externally connected to an infusion pump, and the glaze liquid is transported to the material guiding pipe 802 through the infusion pump; a movable block 803 slidably installed inside the connection box 801; a through hole 8031 opened on the movable block 803; a second pressing rod 804 movably inserted through the bottom of the connection box 801. A sealing ring is arranged between the second pressing rod 804 and the connection box 801 to improve the sealing effect, and the top of the second pressing rod 804 is fixedly installed at the bottom of the movable block 803; a second spring 805 sleeved on the second pressing rod 804, and one end of the second spring 805 is fixedly connected to the bottom of the connection box 801, and the other end of the second spring 805 is fixedly installed on the surface of the other end of the second pressing rod 804; and a trapezoidal pressing strip 806 fixedly installed on the inner wall of the box body 1 and cooperating with the bottom of the adjacent second pressing rod 804.

[0051] The opening direction of the through hole 8031 is the same as the communication direction of the annular spraying pipe 7 and the material guiding pipe 802, and at least 12 nozzles are arranged along the circumference of the annular spraying pipe 7 to make the glazing more uniform. Considering that during the separate upper spraying of glaze, due to the gravity of the glaze itself, it will fall rapidly during spraying, resulting in a short attachment time of the glaze and possibly affecting the glazing effect on the surface of the porcelain embryo. During the movement of the annular spraying pipe 7 on the air cylinder 502 and the annular spraying pipe 7 on the moving plate 6, when the guiding pin 306 on the moving block 307 moves below the guiding groove 308, the bottom of the second pressing rod 804 at one end of the two annular spraying pipes 7 presses against the top of the trapezoidal pressing strip 806, so that the second pressing rod 804 pushes the movable block 803 to move upward in the connection box 801. At this time, the through hole 8031 is communicated with the annular spraying pipe 7 and the material guiding pipe 802, and the glaze liquid is sprayed out from the two upper and lower annular spraying pipes 7 to glaze the outer wall of the porcelain embryo. The upper spraying of glaze and the lower spraying of glaze spray the porcelain embryo up and down. The collision and dispersion of the glaze in two directions further extend the contact time between the glaze and the porcelain embryo and improve the glazing effect.

[0052] In this embodiment, as Figures 1 to 14 shown, the limiting assembly 9 includes a connection block 901 fixedly installed on the conveyor belt 2; a movable push rod 902 movably penetrating through the connection block 901; a fixed ring 903 fixedly installed on the movable push rod 902; a first return spring 904 sleeved on the movable push rod 902, and one end of the first return spring 904 is fixedly connected to the bottom of the fixed ring 903, and the other end of the first return spring 904 is fixedly connected to the surface of the connection block 901; a limiting rod 905 rotatably installed on the connection block 901, and the bottom of one end of the limiting rod 905 is placed on the top of the movable push rod 902; and a pressing block 906 fixedly installed at the lower end of the moving block 307, and the pressing block 906 is located above one end of the limiting rod 905.

[0053] When the moving block 307 drives the tightening assembly 5 to descend to clamp and fix the mouth of the porcelain embryo, the pressing block 906 at the lower end of the moving block 307 presses on one end of the limiting rod 905, causing the limiting rod 905 to flip. At this time, the limiting rod 905 releases the shielding of the porcelain embryo, so as to facilitate the horizontal movement of the porcelain embryo driven by the moving block 307 after clamping. When the pressing block 906 moves to release the pressing on the limiting rod 905, the first return spring 904 is elastically reset after being stressed and pushes the limiting rod 905 to rotate in the reverse direction, so that the limiting rod 905 shields the subsequent porcelain embryo again, facilitating the clamping of the next porcelain embryo. Then, the first hinge rod 305 slidably installed on the fixed sleeve 304 drives the guide pin 306 to move horizontally on the guide groove 308, so that the guide pin 306 drives the moving block 307 and the moving plate 6 to move horizontally to glaze the clamped porcelain embryo.

[0054] In this embodiment, as Figures 1 to 14 shown, the clamping assembly 11 includes a mounting block 1101 fixedly installed on the turntable 10; main magnetic blocks 1102 symmetrically and fixedly installed on one side of the mounting block 1101; slave magnetic blocks 1103 attracted to the main magnetic blocks 1102. It should be noted here that the slave magnetic blocks 1103 and the main magnetic blocks 1102 have opposite magnetic poles and attract each other; a U-shaped plate 1104 fixedly connected between the two slave magnetic blocks 1103; L-shaped movable rods 1105 symmetrically and movably installed on the U-shaped plate 1104; clamping plates 1106 fixedly installed at one end of the L-shaped movable rods 1105; and second return springs 1107 sleeved on the L-shaped movable rods 1105, and both ends of the second return springs 1107 are fixedly installed between the adjacent clamping plates 1106 and the inner wall of the U-shaped plate 1104; push blocks 14 are symmetrically and fixedly connected to the side wall of a group of annular spray pipes 7, and the two push blocks 14 cooperate with the corresponding L-shaped movable rods 1105. It should be added here that the side wall of the push block 14 is provided with a trapezoidal inclined surface that cooperates with the corresponding L-shaped movable rod 1105; and a bottom support 1108 fixedly installed on the U-shaped plate 1104. A rotating assembly 13 for driving the clamped porcelain embryo to rotate is further provided on the turntable 10.

[0055] After the glazed ceramic blank moves horizontally into place, the bottom of the second pressing rod 804 releases the extrusion of the corresponding trapezoidal pressing strip 806. Driven by the elastic reset of the second spring 805, the second pressing rod 804 drives the movable block 803 to move downward, so that the movable block 803 blocks the glaze liquid and stops glazing. And when the supporting component 5 drives the ceramic blank to move towards the position of the clamping plate 1106, the pushing blocks 14 fixed on both sides of the annular spraying pipe 7 located above squeeze against the corresponding L-shaped movable rods 1105 through the trapezoidal side walls, causing the two symmetric L-shaped movable rods 1105 on the U-shaped plate 1104 to move in opposite directions simultaneously. The two clamping plates 1106 are in an open state. After the ceramic blank on the supporting component 5 moves between the two clamping plates 1106, the L-shaped movable rods 1105 are released from the pressing against the trapezoidal inclined surface of the side wall of the pushing block 14. The L-shaped movable rods 1105 are elastically reset through the second reset spring 1107, so that the two clamping plates 1106 fix the glazed ceramic blank. At this time, the guide pin 306 moves vertically upward again along the guide of the guide groove 308, causing the guide pin 306 to drive the movable block 307 to move vertically upward. When the movable block 307 moves vertically upward, since the ceramic blank is in a clamped and fixed state, the L-shaped pressing rod 501 drives the piston disc 503 fixed on its surface to move upward. At this time, the gas inside the airbag 506 enters the lower end inside the air cylinder 502 through the telescopic hose 505, and the airbag 506 contracts, releasing the tight fixing of the bottle mouth, so that the airbag 506 automatically detaches from the bottle mouth. After the movable block 307 drives the airbag 506 to move upward in place, the guide pin 306 drives the movable block 307 and the moving plate 6 to move horizontally for reset, and the glazing operation of the next ceramic blank is carried out.

[0056] In this embodiment, as Figures 1 to 14As shown, the rotating assembly 13 includes a connecting column 1301 fixedly installed on the turntable 10; a limiting groove 1302 formed on the outer wall of the connecting column 1301; a movable sleeve 1303 sleeved on the connecting column 1301; a limiting pin 1304 fixedly installed on the inner wall of the movable sleeve 1303, and the limiting pin 1304 is slidably installed inside the limiting groove 1302. It should be added here that the limiting groove 1302 has two symmetric arc grooves and two symmetric vertical grooves connected end to end, and is arranged in a stepped shape on the outer wall of the connecting column 1301. When the limiting pin 1304 moves down in place, the limiting pin 1304 is located inside the arc groove, and when the limiting pin 1304 moves up in place, the limiting pin 1304 is located inside the vertical groove; a second guide rod 1305 fixedly installed on the movable sleeve 1303; a limiting block 1306 sleeved on the second guide rod 1305, and the limiting block 1306 is fixedly installed on the outer wall of the box body 1; a third return spring 1307 sleeved on the second guide rod 1305, and one end of the third return spring 1307 is fixedly installed at the bottom of the limiting block 1306, and the other end of the third return spring 1307 is fixedly installed on the top surface of the movable sleeve 1303; and a movable frame 1308 fixedly installed on the outer wall of the movable sleeve 1303, and the movable frame 1308 is slidably installed inside the other side of the box body 1. A turning assembly 12 is arranged between the lower end surface of the connecting column 1301 and the four mounting blocks 1101.

[0057] During the upward movement of the L-shaped pressing rod 501, the top of the L-shaped pressing rod 501 will squeeze against the bottom of the movable frame 1308, thereby driving the movable frame 1308 to rise, causing the movable frame 1308 to drive the fixed movable sleeve 1303 to move upward. At this time, the limiting pin 1304 on the inner wall of the movable sleeve 1303 slides towards the arc groove position on the limiting groove 1302. Through the vertical upward movement of the limiting pin 1304, the connecting column 1301 drives the turntable 10 to rotate along the arc groove position. When the limiting pin 1304 moves up in place, the connecting column 1301 drives the turntable 10 to complete a 90-degree rotation, thereby automatically converting the position of the clamped porcelain blank, facilitating the blanking work of the porcelain blank. When the L-shaped pressing rod 501 moves horizontally after moving vertically up in place, the L-shaped pressing rod 501 releases the extrusion on the movable frame 1308. At this time, the movable sleeve 1303 is elastically reset by the third return spring 1307, pushing the movable sleeve 1303 to move downward, causing the limiting pin 1304 on the inner wall of the movable sleeve 1303 to move downward along the vertical groove on the limiting groove 1302 to complete the reset, facilitating the next rotation.

[0058] In this embodiment, as Figures 1 to 14As shown in the figure, the flipping assembly 12 includes a connecting sleeve 1201 sleeved on the lower end surface of the connecting column 1301, and one end of the connecting sleeve 1201 is fixedly installed on the box body 1; arc-shaped racks 1202 symmetrically and fixedly installed at the bottom of the connecting sleeve 1201; a bevel gear shaft 1203 rotatably installed on the mounting block 1101, the surface of the bevel gear shaft 1203 is rotatably installed with the inner wall of the mounting block 1101 through a bearing, and one end of the bevel gear shaft 1203 meshes with the corresponding arc-shaped rack 1202, and the other end of the bevel gear shaft 1203 is fixedly connected to the adjacent U-shaped plate 1104.

[0059] During the rotation of the turntable 10 driven by the connecting column 1301, the mounting block 1101 on the turntable 10 rotates, so that the bevel gear shaft 1203 rotatably installed inside the mounting block 1101 meshes with the arc-shaped rack 1202 at the bottom of the connecting sleeve 1201 fixedly installed on the box body 1. After the meshing is completed, the bevel gear shaft 1203 drives the U-shaped plate 1104 to flip 180 degrees. At this time, after flipping 180 degrees, the glaze on the porcelain blank flows reversely, and after the porcelain blank is flipped, it flows back, further improving the glazing effect of the porcelain blank. And after the U-shaped plate 1104 completes a 180-degree flip, the main magnetic block 1102 attracts and combines with the corresponding slave magnetic block 1103, restricting the shaking of the U-shaped plate 1104 and improving the stability of the porcelain blank after flipping.

[0060] In this embodiment, as Figures 1 to 14 shown, a method for using a glazing device for ceramic production includes the following steps:

[0061] S1. First, fix the porcelain embryo on the conveyor belt 2. When the moving block 307 approaches the conveyor belt 2, at this time, the guide pin 306 is located on one side of the guide groove 308. During the rotation of the guide pin 306 driven by the first hinge rod 305, the guide pin 306 moves vertically downward along the guide of the guide groove 308. At this time, the guide pin 306 drives the moving block 307 to move vertically downward, so that the L-shaped pressing rod 501 on the moving block 307 drives the air cylinder 502 to descend. When the air cylinder 502 descends to the bottle mouth of the porcelain embryo, the bottom of the air cylinder 502 presses on the top position of the porcelain embryo to limit its movement. Through the continuous descent of the L-shaped pressing rod 501, the L-shaped pressing rod 501 drives the piston disc 503 fixed on the surface to move downward, so that the air bag 506 at the bottom of the L-shaped pressing rod 501 moves into the interior of the bottle mouth of the porcelain embryo. And during the downward movement of the piston disc 503, the piston disc 503 squeezes the gas inside the lower end of the air cylinder 502, so that the gas enters the air bag 506 through the telescopic hose 505. The air bag 506 begins to expand, seals the bottle mouth of the porcelain embryo, and tightens and fixes the bottle mouth. When the moving block 307 drives the tightening assembly 5 to descend to clamp and fix the bottle mouth of the porcelain embryo, the pressing block 906 at the lower end of the moving block 307 presses on one end of the limiting rod 905, so that the limiting rod 905 flips. At this time, the limiting rod 905 releases the shielding of the porcelain embryo, so as to facilitate the moving block 307 to drive the clamped porcelain embryo to move horizontally. At the same time, the moving block 307 drives the annular spraying pipe 7 on the air cylinder 502 and the annular spraying pipe 7 on the moving plate 6 to move.

[0062] S2. Then, the first hinge rod 305 slidably installed on the fixed sleeve 304 drives the guide pin 306 to move horizontally on the guide groove 308, so that the guide pin 306 drives the moving block 307 and the moving plate 6 to move horizontally. At this time, the moving block 307 moves away from the first pressing rod 405, and the first spring 406 elastically resets. The second hinge rod 404 hinged at the bottom of the first pressing rod 405 pulls the hinged rack 402 to move, shields the corresponding porcelain embryo, and the other rack 402 moves and contracts, so that the porcelain embryo moves to one end of the conveyor belt 2, facilitating the next glazing operation. In this way, the intermittent conveying of the porcelain embryo is realized repeatedly.

[0063] S3. During the movement of the annular spraying pipe 7 on the air cylinder 502 and the annular spraying pipe 7 on the moving plate 6, when the guide pin 306 on the moving block 307 moves to the lower part of the guide groove 308, the bottom of the second pressing rod 804 at one end of the two annular spraying pipes 7 presses on the top of the trapezoidal pressing strip 806 on the inner wall of the box body 1, so that the second pressing rod 804 pushes the moving block 803 to move upward above the connecting box 801. At this time, the through hole 8031 is communicated with the annular spraying pipe 7 and the guide pipe 802, and the glaze liquid is sprayed out from the upper and lower two annular spraying pipes 7 to glaze the outer wall of the porcelain embryo.

[0064] S4. After the glazed porcelain embryo moves horizontally into position, the bottom of the second pressing rod 804 releases the extrusion of the corresponding trapezoidal pressing strip 806. Driven by the elastic reset of the second spring 805, the second pressing rod 804 drives the movable block 803 to move downward, so that the movable block 803 blocks the glaze liquid and stops glazing. Moreover, when the supporting assembly 5 drives the porcelain embryo to move towards the clamping plate 1106, the pushing blocks 14 fixed on both sides of the upper annular spraying pipe 7 squeeze against the corresponding L-shaped movable rods 1105 through the trapezoidal side walls, causing the two symmetric L-shaped movable rods 1105 on the U-shaped plate 1104 to move in opposite directions simultaneously. The two clamping plates 1106 are in an open state. After the porcelain embryo on the supporting assembly 5 moves between the two clamping plates 1106, the L-shaped movable rod 1105 is released from the pressing against the trapezoidal inclined surface of the side wall of the pushing block 14. The L-shaped movable rod 1105 is elastically reset through the second reset spring 1107, so that the two clamping plates 1106 fix the glazed porcelain embryo.

[0065] S5. Then the guide pin 306 moves vertically upward again along the guide of the guide groove 308, so that the guide pin 306 drives the movable block 307 to move vertically upward. When the movable block 307 moves vertically upward, since the porcelain embryo is in a clamped and fixed state, the L-shaped pressing rod 501 drives the piston disc 503 fixed on the surface to move upward. At this time, the gas inside the airbag 506 enters the lower end inside the air cylinder 502 through the telescopic hose 505, and the airbag 506 contracts, releasing the tight fixing of the bottle mouth, so that the airbag 506 automatically detaches from the bottle mouth. After the movable block 307 drives the airbag 506 to move upward in place, the guide pin 306 drives the movable block 307 and the moving plate 6 to move horizontally for reset, and performs the glazing operation on the next porcelain embryo.

[0066] S6. When the L-shaped pressing rod 501 moves upward, the top of the L-shaped pressing rod 501 will squeeze against the bottom of the movable frame 1308, thereby driving the movable frame 1308 to rise, so that the movable frame 1308 drives the fixed movable sleeve 1303 to move upward. At this time, the limit pin 1304 on the inner wall of the movable sleeve 1303 slides towards the arc groove on the limit groove 1302. Through the vertical upward movement of the limit pin 1304, the connecting column 1301 drives the turntable 10 to rotate along the arc groove position. When the limit pin 1304 moves upward in place, the connecting column 1301 drives the turntable 10 to complete a 90-degree rotation, thereby automatically converting the position of the clamped porcelain embryo. When the L-shaped pressing rod 501 moves horizontally after moving vertically upward in place, the L-shaped pressing rod 501 releases the extrusion of the movable frame 1308. At this time, the movable sleeve 1303 is elastically reset through the third reset spring 1307, pushing the movable sleeve 1303 to move downward, so that the limit pin 1304 on the inner wall of the movable sleeve 1303 moves downward along the vertical groove on the limit groove 1302 to complete the reset.

[0067] S7. While the connecting column 1301 drives the turntable 10 to rotate, the mounting block 1101 on the turntable 10 rotates, causing the bevel gear shaft 1203 rotatably installed inside the mounting block 1101 to mesh with the arc-shaped rack 1202 at the bottom of the connecting sleeve 1201 fixedly installed on the box body 1, so that the bevel gear shaft 1203 drives the U-shaped plate 1104 to flip 180 degrees. At this time, after flipping 180 degrees, the glaze on the porcelain blank flows in the reverse direction. And after the U-shaped plate 1104 completes the 180-degree flip, the main magnet block 1102 attracts and combines with the corresponding slave magnet block 1103 to limit the sway of the U-shaped plate 1104.

8. A method for using a glazing device for ceramic production, characterized in that: Using a glazing device for ceramic production as described in any one of claims 1 to 7 comprises the following steps: S1. First, the porcelain embryo on the conveyor belt (2) is fixed. When the moving block (307) is close to the conveyor belt (2), the guide pin (306) is located on one side of the guide groove (308). When the first hinge rod (305) drives the guide pin (306) to rotate, the guide pin (306) moves vertically downward along the guide of the guide groove (308). At this time, the guide pin (306) drives the moving block (307) to move vertically downward, so that the L-shaped pressure rod (501) on the moving block (307) drives the gas cylinder (502) to descend. When the gas cylinder (502) descends to the bottle mouth of the porcelain embryo, the bottom of the gas cylinder (502) squeezes the top position of the porcelain embryo to restrict its movement. Through the continued descent of the L-shaped pressure rod (501), the L-shaped pressure rod (501) drives the piston disk (503) fixed on the surface to move downward, so that the air bag (506) at the bottom of the L-shaped pressure rod (501) moves. When the piston plate (503) moves downward, the piston plate (503) squeezes the gas inside the lower end of the gas cylinder (502), so that the gas enters the air bag (506) through the telescopic hose (505), and the air bag (506) begins to expand, blocking the mouth of the porcelain embryo bottle and tightening and fixing the bottle mouth. When the moving block (307) drives the tightening assembly (5) to descend to clamp and fix the mouth of the porcelain embryo bottle, the pressing block (906) at the lower end of the moving block (307) presses on one end of the limiting rod (905), so that the limiting rod (905) turns over. At this time, the limiting rod (905) releases the shielding of the porcelain embryo, so that the moving block (307) drives the clamped porcelain embryo to move horizontally. At the same time, the moving block (307) drives the annular spraying pipe (7) on the gas cylinder (502) and the annular spraying pipe (7) on the moving plate (6) to move; S2. After that, the first hinged rod (305) slidably mounted on the fixed sleeve (304) drives the guide pin (306) to move horizontally on the guide groove (308), so that the guide pin (306) drives the moving block (307) and the moving plate (6) to move horizontally. At this time, the moving block (307) is away from the first pressure rod (405), and the first spring (406) is elastically reset. The second hinged rod (404) hinged at the bottom of the first pressure rod (405) pulls the hinged rack (402) to move, thereby shielding the corresponding porcelain embryo, and the other rack (402) moves and contracts, so that the porcelain embryo moves toward one end of the conveyor belt (2) to facilitate the next glazing operation. This is repeated to achieve intermittent transportation of the porcelain embryo; S3, when the annular spraying pipe (7) on the air cylinder (502) and the annular spraying pipe (7) on the movable plate (6) are moving, when the guide pin (306) on the movable block (307) moves to the bottom of the guide groove (308), the bottom of the second pressure rod (804) at one end of the two annular spraying pipes (7) is pressed against the top of the trapezoidal pressure strip (806) on the inner wall of the box body (1), so that the second pressure rod (804) pushes the movable block (803) to move above the connecting box (801), and at this time, the through hole (8031) is connected with the annular spraying pipe (7) and the guide pipe (802), and the glaze liquid is sprayed from the upper and lower annular spraying pipes (7) to glaze the outer wall of the porcelain embryo; S4. When the glazed porcelain embryo is laterally moved into position, the bottom of the second pressing rod (804) releases the squeezing of the corresponding trapezoidal pressure strip (806), and the second pressing rod (804) drives the movable block (803) to move downward under the elastic reset of the second spring (805), so that the movable block (803) blocks the glaze liquid and stops glazing. When the tightening assembly (5) drives the porcelain embryo to move toward the clamping plate (1106), the push blocks (14) fixed on both sides of the upper annular spraying pipe (7) squeeze the corresponding L-shaped movable block through the trapezoidal side wall. The movable rod (1105) is moved on the U-shaped plate (1104), so that the two symmetrical L-shaped movable rods (1105) on the U-shaped plate (1104) move in opposite directions at the same time, and the two clamping plates (1106) are in a stretched state. When the porcelain embryo on the tightening component (5) moves between the two clamping plates (1106), the L-shaped movable rod (1105) releases the pressure against the trapezoidal inclined surface of the side wall of the push block (14), and the L-shaped movable rod (1105) is elastically reset by the second reset spring (1107), so that the two clamping plates (1106) fix the porcelain embryo after glazing. S5, then the guide pin (306) moves vertically upward again along the guide of the guide groove (308), so that the guide pin (306) drives the moving block (307) to move vertically upward. When the moving block (307) moves vertically upward, since the porcelain embryo is in a clamped fixed state, the L-shaped pressure rod (501) drives the piston plate (503) fixed on the surface to move upward. At this time, the internal gas of the airbag (506) enters the lower end of the gas cylinder (502) through the telescopic hose (505), and the airbag (506) contracts, releasing the tightening and fixing of the bottle mouth, so that the airbag (506) automatically detaches from the bottle mouth. After the moving block (307) drives the airbag (506) to move upward to the right position, the guide pin (306) drives the moving block (307) and the moving plate (6) to move horizontally again to reset, and the glazing operation of the next porcelain embryo is carried out; S6. When the L-shaped pressure rod (501) moves upward, the top of the L-shaped pressure rod (501) will be pressed against the bottom of the movable frame (1308), thereby driving the movable frame (1308) to rise, so that the movable frame (1308) drives the fixed movable sleeve (1303) to move upward. At this time, the limit pin (1304) on the inner wall of the movable sleeve (1303) slides toward the arc groove position on the limit groove (1302). Through the vertical upward movement of the limit pin (1304), the connecting column (1301) drives the turntable (10) to rotate along the arc groove position. When the limit pin (1304) is moved upward, the rotating shaft (10) is rotated. After moving to the right position, the connecting column (1301) drives the turntable (10) to complete a 90-degree rotation, thereby automatically changing the position of the clamped porcelain embryo. When the L-shaped pressure rod (501) moves vertically upward to the right position and then moves horizontally, the L-shaped pressure rod (501) releases the squeezing and pushing of the movable frame (1308). At this time, the movable sleeve (1303) is elastically reset by the third reset spring (1307), pushing the movable sleeve (1303) downward, so that the limit pin (1304) on the inner wall of the movable sleeve (1303) moves downward along the vertical groove on the limit groove (1302), completing the reset. S7. While the connecting column (1301) drives the turntable (10) to rotate, the mounting block (1101) on the turntable (10) rotates, so that the bevel gear shaft (1203) rotatably mounted inside the mounting block (1101) engages with the arc-shaped rack (1202) at the bottom of the connecting sleeve (1201) fixedly mounted on the housing (1), so that the bevel gear shaft (1203) drives the U-shaped plate (1104) to flip 180 degrees. At this time, after flipping 180 degrees, the glaze on the porcelain embryo flows in the opposite direction, and after the U-shaped plate (1104) completes the flip of 180 degrees, the main magnetic block (1102) and the corresponding slave magnetic block (1103) are attracted to limit the shaking of the U-shaped plate (1104).
