Description

Technical Field

[0001] This invention relates to the field of ceramic glazing, and more specifically to a ceramic glaze and its processing method. Background Technology

[0002] Ceramic glazing is the process of applying glaze to the surface of ceramic products. The general steps for ceramic glazing are as follows: 1. Prepare the ceramic product; 2. Prepare the glaze; 3. Apply the glaze; 4. Dry; 5. Firing; 6. Cooling and cleaning. The evenness of the glaze application has a significant impact on the final quality of the ceramic product. Uneven application can lead to inconsistencies in color, texture, and gloss, and even problems like crazing. When spraying ceramic glaze, a spraying mechanism is required. In existing spraying mechanisms, the distance between the nozzle and the uncooked ceramic surface is fixed. This causes uneven glaze application to the surface, particularly in depressions and protrusions, which can negatively affect the subsequent firing results. Summary of the Invention

[0003] This invention provides a ceramic glaze and its processing method, the purpose of which is to uniformly spray the ceramic glaze onto the surface of unglazed pottery.

[0004] The above objectives are achieved through the following technical solutions:

[0006] Step 1: Mix and grind silicon dioxide, calcium oxide, magnesium oxide and sodium oxide;

[0007] Step 2: Add water to the ground mixture and stir to form a ceramic glaze;

[0008] Step 3: Load the ceramic glaze into the container and place the unglazed pottery inside the spraying equipment;

[0009] Step 4: Drive the threaded rod to rotate simultaneously.

[0010] The ceramic glaze contains 50% silicon dioxide, 30% calcium oxide, 10% sodium oxide and 10% magnesium oxide.

[0011] The spraying equipment includes a fixed plate with six sliding tables slidably connected to it, and a turntable rotatably connected above the fixed plate. Each sliding table is slidably connected to the turntable.

Detailed Implementation

[0027] In the description of this invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0028] The invention will now be further described with reference to the accompanying drawings.

[0029] like Figure 1 A method for processing ceramic glaze includes the following steps:

[0030] Step 1: Mix and grind silicon dioxide, calcium oxide, magnesium oxide and sodium oxide;

[0031] Step 2: Add water to the ground mixture and stir to form a ceramic glaze;

[0032] Step 3: Load the ceramic glaze into the container and place the unglazed pottery inside the spraying equipment;

[0033] Step 4: Drive the threaded rod 401 to rotate simultaneously.

[0034] The ceramic glaze contains 50% silica, 30% calcium oxide, 10% sodium oxide, and 10% magnesium oxide. Silica is the main glass-forming agent in the glaze, and its content affects the glaze's transparency, gloss, and stability. Calcium oxide affects the glaze's melting properties, color, and stability. Sodium oxide contributes significantly to the glaze's melting process and optical properties. Magnesium oxide is used to modify the glaze's melting properties and stability.

[0035] like Figures 3 to 6 To achieve the goal of uniformly spraying ceramic glaze;

[0036] Each slide 11 has protrusions at both the top and bottom ends. The fixed plate 12 has a first slide groove corresponding to the protrusion at the bottom of the slide 11. The protrusion at the bottom of each slide 11 is slidably connected in the first slide groove on the fixed plate 12. The turntable 202 has a second slide groove. The protrusion at the top of each slide 11 is slidably connected in the second slide groove on the turntable 202.

[0037] The direction of the first groove on the fixed plate 12 is the same as the direction of the diameter line of the fixed plate 12, thus ensuring that the slide table 11 can slide along the first groove of the fixed plate 12 to the inner and outer sides. The direction of the second groove on the turntable 202 is at a 30° angle relative to the diameter line of the turntable 202, and the projected length of the second groove on the diameter line is equal to the length of the first groove. Thus, during the glaze spraying process, the fixed plate 12 moves from top to bottom along the surface of the unglazed pottery, thereby driving the slide table 11 and the turntable 202 to move from top to bottom. The slide table 11 is equipped with a spray nozzle 104. The glaze is sprayed out from the spray nozzle 104 and adheres to the surface of the unglazed ceramic. When the drive turntable 202 rotates clockwise, it drives the slide table 11 to move inward through the cooperation of the first and second sliding grooves. Similarly, the drive plate 202 rotates counterclockwise to drive the slide table 11 to move outward. As the curve of the unglazed ceramic surface changes, the distance between the spray nozzle 104 and the nozzle is kept consistent, thereby ensuring that the ceramic glaze can be evenly adhered to the surface of the unglazed ceramic during the spraying process.

[0038] like Figure 5 and Figure 6 To ensure that the glaze spraying direction is always perpendicular to the surface of the unglazed pottery;

[0039] Two rotating blocks 101 are rotatably connected to each slide 11, and a first tension spring 102 is fixed between two adjacent rotating blocks 101 on two adjacent slides 11.

[0040] During the glaze spraying process, it is necessary to ensure that the spraying direction is always perpendicular to the surface of the unglazed ceramic to ensure the uniformity of the spraying. When the drive turntable 202 rotates, the relative rotation between the turntable 202 and the fixed plate 12 causes the slide table 11 to rotate along the protrusions at its upper and lower ends. This causes the direction of the spray nozzle 104 located on its inner side to change, and the first tension spring 102 can pull the two rotating blocks 101. The elastic coefficient of each first tension spring 102 is the same, which ensures that the two rotating blocks 101 on each slide table 11 are subjected to the same tension, and thus ensures that the tension on the left and right sides of the slide table 11 is the same. Therefore, when the slide table 11 moves inward and outward, the tension on both sides can always ensure that the inner spray nozzle 104 is facing the direction of the unglazed ceramic, thereby ensuring the spraying effect.

[0041] like Figure 6 , Figure 7 and Figure 8 To achieve the purpose of spraying in both the upper and lower directions;

[0042] Each slide 11 is fixedly connected to a sealing seat 103, and each sealing seat 103 is rotatably connected to a nozzle 104. Each nozzle 104 is provided with multiple fine holes, and each nozzle 104 is fixedly connected to a gear 105. Each gear 105 is meshed with a rack 201, and each rack 201 is fixedly connected to a fixed plate 12.

[0043] When the slide table 11 moves along the diameter direction, in order to ensure that the spray nozzle 104 sprays evenly in both the upper and lower directions, the slide table 11 moves inward, driving the sealing seat 103 to move inward, which in turn drives the spray nozzle 104 to move inward, thereby driving the gear 105 to move. At the same time, the rack 201 meshes with the gear 105 to rotate, which in turn drives the spray nozzle 104 to rotate. When the spray nozzle 104 is working, some of the fine holes are blocked by the sealing seat 103, so that it can only spray glaze inward. When the spray nozzle 104 rotates, the fine holes follow the rotation, so that when the spray nozzle 104 moves inward, it can also spray the terracotta in both the upper and lower directions, thereby achieving the effect of even spraying in all directions.

[0044] like Figure 1 and Figure 10 In order to achieve the purpose of delivering the glaze to the nozzle 104;

[0045] Each slide 11 is fixedly connected to a hose 106, one end of each hose 106 is rotatably connected to the shaft of the corresponding nozzle 104, and the other end of each hose 106 is fixedly connected to the material barrel.

[0046] After the prepared ceramic glaze is added into the material tank, the glaze flows through the hose 106 to each slide 11. The hose 106 passes through the left and right ends of the sealing seat 103 and is rotatably connected to the rotating shaft of the nozzle 104, so that the glaze can be continuously sprayed out through the nozzle 104 during the movement of the nozzle 104.

[0047] like Figure 2 , Figure 5 and Figure 10 To prevent the hose from obstructing the movement of the slide;

[0048] Each of the hoses 106 is wound with a coil 107, and a spring sheet 403 is fixed inside each coil 107.

[0049] The spraying equipment also includes a bracket 14, with each spring plate 403 fixedly attached to the bracket 14. Multiple limit wheels 402 are rotatably connected to the bracket 14, and each limit wheel 402 is in contact with the corresponding hose 106.

[0050] As the fixed plate 12 moves the slide 11 downwards, part of the hose 106 on the winding barrel 107 is stretched, which in turn causes the winding barrel 107 to rotate, thereby compressing the spring plate 403. At the same time, as one end of the hose 106 moves downwards with the slide 11, the limiting wheel 402 always ensures that the stretched part of the hose 106 is in a vertical state. Then, as the fixed plate 12 moves the slide 11 upwards to reset, the compressed spring plate 403 is restored, causing the winding barrel 107 to rotate and rewind part of the hose 106 onto the winding barrel 107, thereby preventing the hose 106 from shaking and getting stuck in the bracket 14, which would affect the movement of the slide 11.

[0051] like Figure 2 To achieve the purpose of controlling the movement of the fixed plate;

[0052] The bracket 14 is rotatably connected to four threaded rods 401, each threaded rod 401 is threadedly connected to a threaded plate 203, and each threaded plate 203 is fixed to the lower end of the fixed plate 12.

[0053] The lower end of the threaded rod 401 is rotatably connected to the bracket 14, and the upper ends of the threaded rods 401 are connected to each other by a belt. When one threaded rod 401 is driven to rotate, it drives four threaded rods 401 to rotate synchronously, thereby controlling the movement of each threaded plate 203 at the same time, which in turn drives the fixed plate 12 to move up and down, thus ensuring that the fixed plate 12 is horizontal.

[0054] like Figure 9 To achieve the purpose of controlling the movement of the slide 11 according to the shape of the unglazed pottery;

[0055] Two connecting blocks 13 are also fixedly connected to the fixed plate 12. Each connecting block 13 is slidably connected to a slide rod 301. One end of each slide rod 301 is rotatably connected to a rubber wheel 302. The other end of each slide rod 301 is fixedly connected to the fixed plate 12 with a second tension spring 303.

[0056] During the up-and-down movement of the fixed plate 12, the connecting block 13 moves, which in turn moves the slide rod 301. The second tension spring 303 continuously pulls the slide rod 301 forward, so that the rubber wheel 302 is always in contact with the ceramic surface. When the tension spring 303 moves the slide rod 301 inward, the slide rod 301 moves inward relative to the fixed plate 12, which in turn drives the turntable 202 to rotate, thereby driving the slide table 11 to move inward. Similarly, when the slide rod 301 moves outward, it drives the slide table 11 to move outward.
