Description

Technical Field

[0001] This utility model relates to the field of ceramic glazing technology, and in particular to a uniform glazing device for the production of ceramic tableware. Background Technology

[0002] Ceramics are inorganic non-metallic materials made primarily from natural clay through mixing, shaping, drying, and high-temperature sintering. Unglazed ceramic bodies, due to their porous structure, are prone to water penetration and stain absorption, and have a rough surface. Therefore, a glazing process is necessary to enhance their performance and aesthetics. This process involves covering the surface of the ceramic body with a layer of vitreous inorganic glaze, followed by a second high-temperature firing, which melts to form a smooth, dense, and hard protective film. This glaze effectively seals the pores, giving the ceramic its practical function of preventing liquid leakage, significantly enhancing its mechanical strength and ease of cleaning. Furthermore, the glaze itself imparts rich artistic decorative effects, ultimately creating products that combine practicality and artistic value.

[0003] Traditional ceramic glazing processes, especially for tableware, suffer from the following technical drawbacks during the glazing process: First, solid particles tend to settle and stratify when the glaze is left to stand, resulting in uneven glaze concentration and varying glaze thickness across different parts of the ceramic body. This often leads to defects such as color differences and uneven glaze surfaces after firing, necessitating the use of a separate mixer or manual intermittent stirring. Second, during glazing, the ceramic body is often immersed in a fixed position, making it prone to trapping air bubbles in surface depressions or complex structures, forming unglazed "glaze pits." Furthermore, the lack of movement of the ceramic body makes it difficult to ensure uniform glaze coverage of its inner and outer surfaces. Therefore, we propose a uniform glazing device for ceramic tableware production to address these issues. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a uniform glazing device for the production of ceramic tableware.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figures 1-3 As shown, a uniform glazing device for ceramic tableware production is disclosed, including a base frame 1, with a glaze pool 2 fixedly connected to the top of the base frame 1. The glaze pool 2 and the inner frame 3 form an independent glazing work area. Its advantage is that it can limit the range of stirring and workpiece movement, making the glaze concentration more stable in this area and forming an efficient glaze circulation path.

[0021] The inner frame 3 is fixedly connected to the inside of the glaze pool 2. The outer wall of the glaze pool 2 is fixedly connected to the water pumping pipe 4 and the return pipe 5. A diaphragm pump is fixedly connected between the water pumping pipe 4 and the return pipe 5. The water pumping pipe 4 and the return pipe 5 are connected through the external diaphragm pump to form a glaze circulation. The advantage of this is that it can continuously pump up the glaze from the bottom of the glaze pool 2 and return it from the top. Working in conjunction with the T-shaped stirring plate 16, it can completely prevent the glaze solid particles from settling and stratifying, and ensure the absolute uniformity of the glaze composition.

[0022] A geared motor 6 is fixedly connected to the top of the bottom frame 1. An existing encoder (standard model) is installed on the outer wall of the output shaft of the geared motor 6. The encoder detects the rotation angle of the output shaft of the geared motor 6. Two wiring holes 7 are opened on the outer wall of the bottom frame 1. An inverted circular frame 8 is fixedly connected to the top of the output end of the geared motor 6. The outer wall of the inverted circular frame 8 is rotatably connected to the inner wall of the inner frame 3. Through the reciprocating rotation of the geared motor 6, the glaze can be fully stirred and the ceramic can be rotated in the glaze at a suitable speed to achieve uniform coverage. The inverted circular frame 8 ensures smooth rotation and also provides support. Multiple heat dissipation holes are opened on the top of the inverted circular frame 8 for heat dissipation of the geared motor 6.

[0023] An electric push rod 9 is fixedly connected to the top of the inverted circular frame 8. A top frame 11 is fixedly connected to the top of the output end of the electric push rod 9. Two support rods 10 are fixedly connected between the top frame 11 and the inverted circular frame 8. The electric push rod 9 drives the top frame 11 to achieve lifting and lowering action, so as to realize the immersion and lifting of ceramic into and out of the glaze surface.

[0024] The top of the top frame 11 is equipped with a pressing assembly, which includes two cylinders 12. The number of pressing assemblies can be increased on the top of the top frame 11 to make them arranged in a ring, thereby increasing the amount of glazing on the ceramic. The top of the top frame 11 has two sliding holes, and the inner walls of the two sliding holes are slidably connected to the outer walls of the output ends of the two cylinders 12 respectively. The top of the top frame 11 is fixedly connected to the outer walls of the two cylinders 12. The bottom of the output ends of the two cylinders 12 are fixedly connected to the ejector pins 13. The bottom of the ejector pins 13 is equipped with a rubber structure to avoid rigid contact with the ceramic. The cylinders 12 drive the ejector pins 13 to achieve pressing and releasing actions. When pressing, it can firmly fix the bottom of the ceramic tableware to prevent the tableware from tipping over or shifting during glazing and rotation. When releasing, it is convenient to quickly pick up and put away the tableware.

[0025] The bottom of the top frame 11 is fixedly connected to four L-shaped metal rods 14. The four L-shaped metal rods 14 form a tableware support structure in pairs. The L-shaped design can fit the shape of the ceramic tableware placed upside down, providing a stable support point for the tableware. Each of the four L-shaped metal rods 14 is fixedly connected to a connecting plate 15 in pairs.

[0026] Both connecting plates 15 are fixedly connected to T-shaped stirring plates 16 on their outer walls. The T-shaped structure of the T-shaped stirring plates 16 can increase the contact area with the glaze. When rotating, it can fully stir the glaze in the glaze pool 2, effectively preventing the solid particles in the glaze from settling and stratifying, and ensuring that the glaze concentration is uniform.

[0027] Working principle: In use, two ceramic tableware pieces are placed upside down on two sets of L-shaped metal rods 14 respectively. After starting the equipment, the cylinder 12 rotates and drives the ejector pin 13 to move down to press the bottom of the ceramic to prevent it from tipping over. Then, the electric push rod 9 starts, pushing the top frame 11 and the connected L-shaped metal rods 14 to descend as a whole, so that the ceramic is immersed in the glaze of the inner frame 3 of the glaze pool 2. Immediately afterwards, the reduction motor 6 starts and reciprocates, driving the upside-down circular frame 8 and the top frame 11 to rotate back and forth, thereby passing through the L-shaped metal rods 14 to the bottom of the ceramic. The metal rod 14 and the T-shaped stirring plate 16 rotate synchronously. The T-shaped stirring plate 16 continuously stirs the glaze in the glaze pool 2 to ensure uniform concentration. At the same time, the rotating ceramic is evenly covered with glaze in all directions. After glazing is completed, the electric push rod 9 rises to lift the ceramic off the glaze surface, the ejector pin 13 is released, and the glazed ceramic can be removed. The glaze is pumped from the glaze pool 2 through the pumping pipe 4 by the operation of the diaphragm pump, and then sent back to the interior of the glaze pool 2 through the return pipe 5 to achieve circulation.

[0028] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the geared motor 6, electric push rod 9, and cylinder 12 to facilitate the control of the overall operation.
