[0038] Embodiment 1

[0039] To effectively solve the problem of frequent addition of glaze to the brush head when glazing the surface of ceramic bottles, please refer to Figure 1-Figure 8 The present embodiment provides a glazing device for pottery production, which can realize the autonomous glazing of a circular pottery bottle with a regular surface. The glazing device comprises a rotating table 2 installed in the middle of the bottom wall of the protective cover 1 and a pottery bottle 3 placed on the top surface of the rotating table 2. A positioning component 4 is installed on the edge of the protective cover 1. Three glazing components 5 arranged in an annular shape and equidistantly are arranged on the outer surface of the pottery bottle 3. A master control component 6 is installed on the protective cover 1 for controlling the three glazing components 5 to move intermittently from top to bottom and to adjust the distance between the end of the glazing component 5 and the surface of the pottery bottle 3 according to the change of the surface morphology of the pottery bottle 3. In actual application, after the pottery bottle 3 is placed in the middle of the top surface of the rotating table 2, the positioning component 4 is used to press the top of the pottery bottle 3 to avoid the position deviation when the pottery bottle 3 is driven to rotate and glaze. In addition, the coordinated application of the master control component 6 and the glazing component 5 can realize the purpose of automatic glazing on the surface of the pottery bottle 3 with a regular surface.

[0040] Specifically, the glazing component 5 in this embodiment includes a toothed bar frame 501 slidably mounted on the master control component 6, a glazing brush 502 is installed at the bottom of the toothed bar frame 501 near the ceramic bottle 3, a glaze supply structure 503 is arranged on the outside of the protective cover 1, and the glaze supply structure 503 includes a glaze storage box, a feeding pump body and corresponding pipelines, and a supply pipe 504 with one end inserted into the bristles of the glazing brush 502 at multiple points is connected to the output end of the glaze supply structure 503. Several sets of hanging parts are installed on the surface of the supply pipe 504. When glazing the surface of the ceramic bottle 3 at a set height, the glaze in the glaze storage box is extracted by running the feeding pump body, and is transported to the supply pipe 504 through the corresponding pipeline, and finally dispersed to various positions in the bristles of the glazing brush 502, and is delivered at multiple points to ensure the uniformity of the delivery, so that the bristles of the glazing brush 502 always contain glaze, ensuring the uninterrupted glazing of the entire ceramic bottle 3, and at the same time achieving the purpose of autonomous material addition of the glazing brush 502.

[0041] Embodiment 2

[0042] Following the above, if Figure 2-Figure 4 As shown, the supply pipeline 504 includes a plurality of vertically arranged collecting pipes 5041 inserted into the glazing brush 502, a plurality of outlet hoses 5042 inserted into the bristle ends of the glazing brush 502 are connected to one side of the collecting pipe 5041, and round shafts 5043 are installed at both ends of the collecting pipe 5041. Three equidistantly arranged rotating wheels 5044 are rotatably sleeved on the outer surface of the round shaft 5043. A feed pipe 5045 for introducing glaze onto the blades of the rotating wheel 5044 and driving the round shaft 5043 to rotate is installed on the side of the collecting pipe 5041 away from the glazing brush 502, and at least three ring-shaped and equidistantly arranged comb teeth 5046 are installed between the blades of the three rotating wheels 5044. The glaze introduced into the collecting pipe 5041 through the feeding pipe 5045 falls onto the three rotating wheels 5044 installed on the surface of the circular shaft rod 5043 along three points respectively. The impact force of the glaze flowing toward its surface is used to cause the rotating wheels 5044 to rotate irregularly along the outer surface of the circular shaft rod 5043, thereby disturbing the glaze inside the collecting pipe 5041 and driving the comb teeth 5046 to rotate with the center of the circular shaft rod 5043 as a fixed point, so that the glaze is pulled and dispersed, effectively reducing the chance of excessive deposition of glaze on the inner wall or other surfaces of the collecting pipe 5041, thereby avoiding deposition or thick oil layers, and effectively reducing the probability of glaze clogging the outlet hose 5042.

[0043] A Y-shaped tube 5047 is installed on one side of the several feed tubes 5045 away from the collecting tube 5041, so as to pour the glaze into the several feed tubes 5045 respectively. A telescopic tube 5048 is connected to the output end of the glaze supply structure 503, which passes through the hanger and is interconnected with one end of the several Y-shaped tubes 5047. The length and shape of the telescopic tube 5048 itself can be changed accordingly under the action of external force, thereby avoiding hindering the rising, falling and horizontal movement of the glaze brush 502.

[0044] Embodiment 3

[0045] like Figure 4 As shown, the shape of the outlet hose 5042 is arranged in a transitional manner from a circular shape at one end close to the collecting pipe 5041 to a flat shape at the other end, and the width of the flattened end of the outlet hose 5042 is greater than the diameter of the circular end, thereby ensuring smooth flow of the glaze while increasing its coverage area within the bristles of the glaze brush 502.

[0046] Embodiment 4

[0047] Since the surface of the ceramic bottle 3 to be glazed has a certain contraction or expansion arc from top to bottom, when the glazing brush 502 is used to glaze the surface of the ceramic bottle 3 from top to bottom, the lateral position of the glazing brush 502 needs to be frequently adjusted to ensure that the bristle end is always in contact with the surface of the ceramic bottle 3. Figure 1 , Figure 5-Figure 6As shown, the master control assembly 6 in this embodiment includes a positioning ring 601 arranged on the outside of the ceramic bottle 3, at least two connecting hanging plates 602 are installed on the positioning ring 601, an electric telescopic rod 603 for driving the positioning ring 601 to move up and down is installed between the connecting hanging plates 602 and the outer wall of the protective cover 1, an inner gear ring 604 is rotatably sleeved on the bottom of the positioning ring 601, a driving structure 605 is installed on the top of the positioning ring 601 and is matched with the teeth of the inner gear ring 604, three gear columns 606 are rotatably installed on the positioning ring 601 and are matched with the teeth of the inner gear ring 604, and a spur gear 607 is installed at the bottom of the gear column 606 and is matched with the teeth in the tooth bar frame 501. In the process of glazing the surface of the ceramic bottle 3, the telescopic function of the electric telescopic rod 603 is used to drive the positioning ring 601 and its related structures to rise or fall, so as to achieve the purpose of controlling the glazing brush 502 to intermittently descend along the surface of the ceramic bottle 3. The driving structure 605 is composed of a stepper motor and a gear structure installed at the output end of the stepper motor. When the stepper motor is running to drive the gear structure to rotate in a set direction, the inner gear ring 604 can be driven to rotate along the surface of the positioning ring 601, and the three gear columns 606 can be driven to rotate. Finally, with the cooperation of the spur gear 607, the toothed bar frame 501 moves toward or away from the direction where the ceramic bottle 3 is located, thereby ensuring that the bristle end of the glazing brush 502 can always fit the surface of the ceramic bottle 3 after the height is intermittently lowered along the surface of the ceramic bottle 3.

[0048] Embodiment 5

[0049] When the rotating table 2 is used to drive the ceramic bottle 3 to rotate relative to the three glazing brushes 502, the bristle ends of the glazing brushes 502 will react to the surface of the ceramic bottle 3 with a certain force, which may easily cause the ceramic bottle 3 to shift on the rotating table 2. In order to effectively avoid this situation, Figure 1 and Figure 7 As shown, the positioning assembly 4 in this embodiment includes a frame plate installed on the top edge of the protective cover 1, and a hydraulic cylinder 401 is installed on the frame plate. The free end of the hydraulic cylinder 401 is rotatably sleeved with a pressing structure 402. After the ceramic bottle 3 is placed in the middle of the top surface of the rotating table 2, the hydraulic cylinder 401 is operated to extend downward accordingly, thereby driving the pressing structure 402 to move downward, driving the pressing structure 402 to press on the top of the ceramic bottle 3, thereby fixing the ceramic bottle 3 at the corresponding position on the rotating table 2. In addition, when the rotating table 2 is operated to drive the ceramic bottle 3 to rotate, the pressing structure 402 rotates along the free end of the hydraulic cylinder 401.

[0050] Following the above, if Figure 7 and Figure 8As shown, the pressing structure 402 is composed of a sleeve sleeved on the free end of the hydraulic cylinder 401 and a pressure plate plugged into the bottom of the sleeve, a distance sensor 1 403 is installed on the top of the sleeve, and a pressure sensor 404 is installed on the bottom of the sleeve, a curved plate 5011 is installed on one side of one of the toothed bar frames 501, and a distance sensor 2 5012 and a distance sensor 3 5013 are installed on the bottom of the curved plate 5011 and the side close to the ceramic bottle 3, respectively. After the hydraulic cylinder 401 moves downward so that the bottom of the pressure plate is in close contact with the top of the ceramic bottle 3 to be glazed, the pressure sensor 404 inside the sleeve senses the pressure signal, and then the hydraulic cylinder 401 electrically connected to the desired device stops running, and the distance sensor 1 403 starts to monitor the distance N between itself and the upper frame plate, and according to the distance constant M between the bottom of the pressure plate and the top surface of the rotating table 2 at the initial position, the height H1=MN of the ceramic bottle 3 to be glazed is calculated. In the initial state, the two electric telescopic rods 603 maintain the maximum upward advancement state, that is, the positioning ring 601 is located above the ceramic bottle 3. After that, the electric telescopic rods 603 continue to shrink downwards for a certain distance. During the shrinking process, the distance sensor 2 5012 is used to monitor in real time whether the positioning ring 601 reaches the same height as the top of the ceramic bottle 3 according to the height of the ceramic bottle 3 to be glazed. After that, the electric telescopic rods 603 intermittently shrink downwards for a certain distance, and cooperate with the distance sensor 3 5013 to monitor the distance between itself and the surface of the ceramic bottle 3 each time the electric telescopic rods 603 are lowered and shrunk, and cooperate with the stepping motor in the driving structure 605 according to this distance, and finally control the bristle end of the glazing brush 502 to fit the outer surface of the ceramic bottle 3, so as to finally achieve the purpose of adjusting the position of the glazing brush 502 according to the change of the shape of the surface of the ceramic bottle 3 from top to bottom, and ensure that the glazing brush 502 can always fit the surface of the ceramic bottle 3.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
