Description

Technical Field

[0001] The present invention relates to the technical field of ceramic production, and particularly relates to a glazing device for producing ceramic casseroles. Background Art

[0002] There are many ways to glaze casseroles. Among them, the dipping method is simple and effective, and the glazing is complete, so it is adopted by most factories. In the existing method, after the casserole is adsorbed by the device, it is slowly immersed in the glaze liquid in an inclined posture. When the casserole is completely immersed in the glaze liquid, the device drives the casserole to float out of the glaze liquid surface. During this process, the glaze at the liquid surface is exposed to the air for a long time, and the surface moisture evaporates, resulting in an increase in the concentration of the glaze and the formation of a solid film (commonly known as glaze skin). When the casserole is immersed in the glaze liquid, the casserole first contacts the glaze skin on the liquid surface and then contacts the glaze liquid. Since the glaze skin is not firmly bonded to the surface of the casserole, it may crack or peel off during firing, affecting the production quality.

[0003] In summary, the present application proposes a glazing device for producing ceramic casseroles to improve the above-mentioned technical problems. Summary of the Invention

[0021] It further includes a cleaning plate 103; the cleaning plate 103 is connected to the top plate 2; a handle is arranged on the upper side of the cleaning plate 103.

[0022] It further includes a locking rod 104; several locking rods 104 are rotatably connected to the upper side of the top plate 2.

[0023] It further includes a metal ring 105 and a first thin film 106; several first electromagnets 2001 are fixedly connected to the lower side of the top plate 2; the first thin film 106 is fixedly connected to the upper side of the baffle 3; the metal ring 105 is fixedly connected to the upper side of the first thin film 106.

[0024] The liquid discharge port 5001 on the guide cover 5 is directly above the filter screen 4.

[0025] The baffle 3 and the filter screen 4 cooperate to form an inverted conical shape.

[0026] A sponge 10301 is arranged on the lower side of the cleaning plate 103.

[0027] When glazing the finished casserole, the existing method is to adsorb the casserole with a device and slowly immerse the casserole into the glaze liquid in an inclined posture. When the casserole is completely immersed in the glaze liquid, then drive the casserole to float out of the glaze liquid surface through the device. During this process, since the glaze liquid is at room temperature during glazing and the glaze liquid surface is always in contact with the outside air, the glaze on the liquid surface is exposed to the air for a long time, and the surface moisture evaporates, resulting in an increase in the concentration of the glaze and the formation of a solid film (commonly known as glaze skin). When the casserole is immersed in the glaze liquid, the casserole first contacts the glaze skin on the liquid surface and then contacts the glaze liquid. Since the glaze skin is not firmly bonded to the surface of the casserole, it may crack or peel off during firing; Therefore, before glazing the casserole, the worker places the casserole upside down on the baffle 3, then activates the two electric push rods 101 to extend, thereby driving the connecting rod 102 and the baffle 3 to move downward together. Subsequently, the second electromagnet 107 on the front side is controlled to be energized, thereby attracting the guiding cover 5 close to the second electromagnet 107 on the front side. Taking the view from left to right as a reference, the guiding cover 5 rotates counterclockwise with the position where the rotating rod 5002 contacts the baffle 3 as the rotation point, so that the casserole placed on the baffle 3 is immersed in the glaze liquid in the storage tank 1 in an inclined posture, facilitating the discharge of the air inside the casserole. Similarly, when the casserole is immersed in the glaze liquid, the second electromagnet 107 on the front side is stopped from generating magnetism, and then the second electromagnet 107 on the rear side is controlled to be energized. Taking the view from left to right as a reference, then the guiding cover 5 is rotated clockwise to make the casserole fully contact the glaze liquid for glazing. Since the baffle 3 contacts the glaze liquid surface first and the baffle 3 is arranged as a hollow structure with upper and lower connections, considering that the glaze liquid in the storage tank 1 is directly exposed to the outside world, this causes impurities such as external dust particles to easily enter the glaze liquid. When the glaze liquid adheres to the dust particles, it is easy to agglomerate into larger particles. These larger particles will affect the production process of the casserole. Therefore, at the same time, in order to prevent the glaze skin from adhering to the surface of the casserole, when the glaze liquid enters the inside of the baffle 3, the glaze liquid first passes through the filter screen 4, and then the larger glaze particles in the glaze liquid are intercepted to avoid the situation where large particles adhere to the surface of the casserole and cause surface unevenness. At the same time, by using the frustum shape of the baffle 3, the glaze skin is pushed away to the surroundings during its downward movement, so that the glaze skin under the casserole is cleaned by the baffle 3. When the glaze liquid contacts the casserole, there are no large particles and glaze skin in the glaze liquid at this time. Therefore, only the casserole needs to be completely immersed in the glaze liquid for soaking and glazing, which solves the situation where the glaze skin falls off during subsequent firing due to the glaze skin adhering to the surface of the casserole, improves the production quality of the device for the casserole. At the same time, by using the cooperation of the baffle 3 and the filter screen 4 to form a frustum shape, the situation where the glaze skin is pressed into the glaze liquid is reduced, so that most of the glaze skin is pushed away and floats on the surface of the glaze liquid, facilitating the subsequent salvage and cleaning by the worker.

[0028] When the glazed casserole floats out of the liquid surface, in the existing method, the casserole is tilted to pour out the remaining glaze liquid inside it from one side of the casserole. And on the side where the casserole pours out the glaze liquid, a sponge 10301 is needed to scrape off the excess glaze material generated when the glaze liquid drips. This results in the edge of the originally glazed casserole being incomplete due to the wiping of the sponge 10301. Subsequently, workers still need to manually apply the glaze liquid, increasing the production steps and costs. Therefore, a guiding cover 5 is arranged on the upper side of the baffle 3. Since there are edges for placing the pot lid on the inner side of the casserole, the guiding cover 5 supports the edge of the casserole for placing the pot lid. Then, when it is immersed in the glaze liquid and the casserole floats out of the liquid surface, the glaze liquid inside the casserole flows towards the guiding cover 5, converges under the guidance of the guiding cover 5 and flows towards the drain port 5001. Finally, the glaze liquid is drained towards the baffle 3 through the drain port 5001, and finally the glaze liquid flows out from the filter screen 4 and is discharged back into the storage tank 1 again. Thus, it is avoided that the glaze liquid drips along the edge of the casserole, and it is avoided that the glaze liquid forms dripping, resulting in a thicker glaze material at the edge of the casserole. At the same time, there is no need to tilt to pour out the glaze liquid, nor is it necessary to use the sponge 10301 to wipe the glaze material at the pouring position, reducing the labor cost and production steps. Further, since the drain port 5001 on the guiding cover 5 is directly above the filter screen 4, when the glaze liquid flows from the drain port 5001 towards the filter screen 4, the flowing glaze liquid can directly rush towards the filter screen 4, thereby flushing the larger glaze particles intercepted under the filter screen 4, achieving the self-cleaning effect of the device and facilitating the subsequent glazing of the casserole.

[0029] It is also considered that in order to avoid the glaze liquid at the bottom of the casserole from sticking to the supporting plate in the boiler during the firing process and being difficult to take out, it is necessary to wipe the glaze liquid at the bottom of the casserole. Therefore, by starting the two electric push rods 101 to contract simultaneously, the electric push rods 101, the baffle 3 and the guiding cover 5 are driven to move upward. It should be noted that after the casserole is glazed, after controlling the telescopic ends of the two electric push rods 101 to be at the same height, then control the two electric push rods 101 to contract and reset simultaneously, so that the baffle 3 and the guiding cover 5 drive the casserole to move upward in a horizontal posture. When the bottom of the casserole touches the cleaning plate 103, the cleaning plate 103 is used to remove the glaze material at the bottom of the casserole. Finally, control the two electric push rods 101 to extend downward by a certain distance to facilitate the worker to take out the casserole. There is no need for the worker to manually wipe the glaze material at the bottom of the casserole. At the same time, by using the sponge 10301 arranged on the cleaning plate 103, while enhancing the cleaning effect of the glaze material at the bottom of the casserole, it is avoided that the bottom of the casserole is scratched.

[0030] During the process of pushing aside the glaze skin through the baffle 3, considering that when the casserole is immersed in the glaze liquid, the liquid surface is prone to shaking. When the baffle 3 follows the casserole and is completely immersed in the glaze liquid, the glaze skin floating on the liquid surface is likely to drift towards the casserole under the condition of shaking. When the casserole is not completely immersed in the glaze liquid, the glaze skin is still easy to adhere to the surface of the casserole. Therefore, after the worker places the casserole behind the guiding cover 5, the worker then pulls the metal ring 105 upward, and then the first thin film 106. When the metal ring 105 touches the first electromagnet 2001 on the lower side of the top plate 2, the first electromagnet 2001 adsorbs the metal ring 105. At this time, the unfolded first thin film 106 completely covers the casserole, so that the glaze skin on the liquid surface cannot cross the first thin film 106 and the metal ring 105 to touch the casserole on the upper side of the guiding cover 5, thereby completely isolating the glaze skin and further improving the production quality of the casserole by the device.

[0031] It is also considered that since long-term use of the sponge 10301 will cause a large amount of glaze to remain on its surface, for the convenience of workers' maintenance and replacement, the worker only needs to rotate the locking rod 104 to separate the locking rod 104 from the upper side of the cleaning plate 103. The worker only needs to pull the handle on the upper side of the cleaning plate 103 to pull out the cleaning plate 103 and the sponge 10301 from the top plate 2, and then clean the sponge 10301 separately.

[0032] Embodiment 2 Based on Embodiment 1, as Figure 1 and Figure 6 shown, the drainage system includes a circular ring 201, a second thin film 202 and an elastic member 203; the second thin film 202 is fixedly connected to the upper side of the guiding cover 5; the circular ring 201 is fixedly connected to the upper side of the second thin film 202; several elastic members 203 are fixedly connected between the circular ring 201 and the guiding cover 5, and the elastic member 203 is a spring telescopic rod.

[0033] The surface of the second thin film 202 is coated with an anti-adhesion coating to prevent the glaze liquid from remaining in the folds of the second thin film 202.

[0034] When using the guiding cover 5 to cover the lower side of the casserole to guide the glaze liquid, since there is a support ring for supporting the casserole lid on the inner side of the casserole, and the design of the support ring will cause some glaze liquid to stay on the support ring, resulting in a thicker glaze liquid on the surface of the support ring. Therefore, by setting a circular ring 201 and a second thin film 202 on the upper side of the guiding cover 5, after the circular ring 201 contacts the support ring of the casserole for supporting the lid, the elastic member 203 is used to support the circular ring 201, thereby supporting the casserole. When the glazing of the casserole is completed, the electric push rod 101 is used to push the connecting rod 102, the baffle 3 and the guiding cover 5 to move upward, and then the casserole is pushed to move downward under the cleaning plate 103. After the glaze on the bottom of the casserole is removed, the electric push rod 101 is controlled to contract, and then the circular ring 201 is used to push the casserole to continue to move upward. Since the casserole cannot move upward under the restriction of the cleaning plate 103, the elastic member 203 is compressed and contracted, thereby causing the second thin film 202 to contract. At this time, the space formed by the second thin film 202, the guiding cover 5 and the casserole gradually shrinks. At the same time, since the diameter of the liquid discharge port 5001 is much smaller than the diameter of the casserole, the gas in the inner support ring area of the casserole is actively discharged to the liquid discharge port 5001 during the compression process. By means of active compression, the gas in the support ring area is discharged, and the actively flowing gas is used to accelerate the residual glaze liquid on the support ring, improving the production quality of the casserole by the device.
