[0018] The present invention also provides a method for using a glazing device for ceramic production, comprising the following steps:

[0020] S2. Adjusting the glaze position: The position of the discharge head is adjusted by the lifting hydraulic cylinder and the horizontal movement module so that the glaze discharge end of the discharge head is located above the surface of the ceramic body to be glazed;

[0021] S3, rotation control: turning on the first motor to drive the rotating table to rotate, thereby driving the ceramic body to rotate;

[0022] S4. Glazing: Open the pump body and pump the glaze out from the discharge head to the surface of the ceramic body. The glaze flows downward along the surface of the ceramic body and rotates with the ceramic body, so that the glaze completely covers the surface of the ceramic body that needs to be glazed, thereby achieving glazing.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1) During operation, negative pressure fixing members are symmetrically installed on both sides of the vertical plate, so that the ceramic body clamping member can support the inner and outer sides of the ceramic body respectively through the two negative pressure fixing members, thereby avoiding obstruction of the ceramic body surface when clamping and fixing the ceramic body, facilitating complete glazing of the ceramic body, and each clamping seat moves synchronously, facilitating the centering of the ceramic body, improving the uniformity of the glaze on the ceramic body surface, and improving the glazing effect;

[0025] 2) During operation, the end face of the hemispherical rubber head is in close contact with the surface of the ceramic body and deforms, and the fixed plate and the movable plate are separated by the force of the ejector rod, so that the negative pressure cavity is connected to the internal groove. The negative pressure cavity on the side in contact with the ceramic body surface generates negative pressure, while the other side is normal, which facilitates the negative pressure auxiliary fixation of the ceramic body. At the same time, multiple ejector rods are used to increase the clamping area and improve the fixing stability.

[0026] 3) During operation, the rotating cylinder is installed in the rotating groove and driven to rotate until the inclination angle of the vertical plate is the same as the inclination angle of the ceramic body clamping position, so that the hemispherical rubber head and the ceramic body clamping position are perpendicular, which facilitates the close contact between the end face of the hemispherical rubber head and the surface of the ceramic body, ensuring the negative pressure fixation and stability;

[0027] 4) During operation, the piston is fixedly engaged with the clamping rod. Under the joint action of the collar and the guide rod, as the clamping seat moves toward the side away from the bottom tube, the pull rod is continuously pulled downward, causing the first spring to be continuously stretched. When it moves to the clamping position, the piston is released, causing it to move downward under the elastic force of the first spring, thereby generating negative pressure, which facilitates negative pressure-assisted fixation of the ceramic body.

[0028] 5) During operation, the guide rod is moved downward away from one end of the bottom tube, so that the larger the diameter of the ceramic blank, the farther the distance between the clamping seat and the bottom tube, the farther the pull rod moves downward, the greater the elastic force of the first spring, and the greater the negative pressure generated by the piston after release, so that the fixing force and the diameter of the ceramic blank are adaptively adjusted to improve the fixing effect of the ceramic blank.

[0053] Working principle: When the outer wall of the ceramic body needs to be glazed, the ceramic body is fixed by Figure 12 When the inner wall of the ceramic body needs to be glazed, the ceramic body is fixed by attaching Figure 11 Fixing method:

[0054] The surface inclination angle of the ceramic body is determined, and then the rotating cylinder 2091 is driven to rotate by the third motor 2092, so that the inclination angle of the vertical plate 2093 after rotation is the same as the surface inclination angle of the ceramic body. At the same time, two negative pressure fixing members 211 are symmetrically provided on both sides of the vertical plate 2093. When performing the two clamping methods, the two negative pressure fixing members 211 on both sides of the vertical plate 2093 can respectively adhere to the outer wall and the inner wall of the ceramic body, thereby completing the compression and fixation;

[0055] After the ceramic body is placed on the top of the rotating table 203, the second motor 2087 is turned on to drive the screw 2088 to rotate. Since the screw 2088 is threadedly connected to the longitudinal moving plate 2086, the longitudinal moving plate 2086 is driven to move longitudinally inside the bottom tube 2081. A connecting rod 2084 is hingedly installed between the longitudinal moving plate 2086 and the clamping seat 2073. When the longitudinal moving plate 2086 moves longitudinally, the four clamping seats 2073 can move synchronously along the sliding groove 2071, so that the negative pressure fixing member 211 can be in close contact with the outer wall of the ceramic body, thereby coaxially clamping and fixing the ceramic body, which is convenient for subsequent glazing.

[0056] When the hemispherical rubber head 2112 at one end of the side tube 2111 is in close contact with the surface of the ceramic body, the material of the hemispherical rubber head 2112 is rubber, so when the end face of the hemispherical rubber head 2112 is subjected to force, the hemispherical rubber head 2112 is compressed and deformed, while in the original state, the end of the push rod 21111 is flush with the end face of the hemispherical rubber head 2112. After the hemispherical rubber head 2112 is deformed, the end of the push rod 21111 is compressed to push the movable plate 2115 and the fixed plate 2113 to separate and move, so that the negative pressure chamber in the hemispherical rubber head 2112 is connected to the inner cavity of the rotating cylinder 2091, which facilitates subsequent negative pressure adsorption and fixation. At the same time, multiple push rods 21111 can increase the clamping area and improve the clamping stability.

[0057] Bottom holes 2094 are equidistantly formed at the bottom end of the rotating cylinder 2091. During the rotation of the rotating cylinder 2091, the bottom holes 2094 are always connected to the internal groove 2075, so that the negative pressure chamber in the hemispherical rubber head 2112 that contacts the surface of the ceramic body is connected to the internal groove 2075. At the same time, as the clamping seat 2073 moves toward the side away from the bottom cylinder 2081, the collar 2104 is sleeved on the outside of the guide rod 2085, and the end of the guide rod 2085 away from the bottom cylinder 2081 is tilted downward, causing the clamping seat 2073 to move, driving the pull rod 2103 to move downward, causing the first spring 2105 to be continuously stretched until it moves to the clamping position.

[0058] After moving to the clamping position and making the end face of the hemispherical rubber head 2112 close to the surface of the ceramic blank, the electromagnet 21011 is energized to generate an attractive force on the magnetic block 21010. Under the action of the attractive force, the clamping rod 2108 moves toward the inside of the side tube 2107 and disengages from the clamping groove 2106. At this time, the piston 2101 moves downward under the elastic force of the first spring 2105, so that negative pressure is generated in the negative pressure cavity of the hemispherical rubber head 2112, further fixing the ceramic blank. At the same time, the larger the diameter of the ceramic blank, the greater the distance the pull rod 2103 moves downward, and the greater the elastic force of the first spring 2105, so that the subsequent distance the piston 2101 moves downward is longer, and the negative pressure generated is greater, so that the negative pressure fixing force is proportional to the diameter of the ceramic blank, so that the clamping force is adaptively adjusted to the diameter of the ceramic blank;

[0059] After the ceramic body is fixed, the height of the discharge head 304 is adjusted by the lifting hydraulic cylinder 306, and the lateral position of the discharge head 304 is adjusted by the horizontal moving module 305, so that the discharge head 304 can flow out to the top of the surface of the ceramic body that needs to be glazed when discharging glaze, and then the first motor 206 is turned on, and the rotating table 203 is driven to rotate through the gear 205 and the gear ring 204, thereby driving the ceramic body to rotate, and at the same time the pump body 302 is turned on to discharge the glaze stored in the storage barrel 301 from the discharge head 304. The glaze flows downward along the surface of the ceramic body and continuously adheres to the surface of the ceramic body as the ceramic body rotates, completing the glazing. During the glazing process, the glaze flowing to the rotating table 203 flows from the sliding groove 2071 and the middle groove 2072 into the collection box 201 for storage. When the switch valve on the bottom pipe 202 is opened, the glaze flows back to the storage barrel 301 through the connecting hose and the return pipe, saving glaze.
