[0002] Large ceramic workpiece machining involves cutting, grinding, polishing, and glazing large, complex ceramic materials using specialized equipment and techniques. During machining, the strength, hardness, and dimensional accuracy of the ceramic material must be ensured, while also minimizing the degradation of material properties caused by high temperatures and high pressures.

[0003] Ceramic pipes are a type of large ceramic workpiece, primarily used in the chemical and environmental protection industries. They exhibit corrosion and high-temperature resistance. Glazing is a crucial step in ceramic pipe processing. By evenly applying glaze to the pipe surface, a smooth, aesthetically pleasing coating is formed, enhancing the pipe's wear resistance and decorative properties. When glazing a longer pipe, the pipe is placed horizontally and rotated to spray the glaze onto its surface. After the glaze on the outer surface solidifies, the glaze is sprayed onto the interior of the pipe. This prevents the glaze from being squeezed before solidification, which could damage, deform, or crack the glaze layer.

[0004] The disadvantage of the existing technical solution is that when spraying glaze on ceramic pipes, the glaze spraying operation needs to be carried out twice, and the glaze spraying efficiency is low. Utility Model Content

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1-4As shown, an automatic glaze spraying device for large ceramic workpieces includes an isolation box 1, a glaze output device 11 is provided inside the isolation box 1, and also includes a support base 5 arranged at the bottom of the isolation box 1, a support plate 6 is fixedly connected to the support base 5, a circular opening is provided in the middle of the support plate 6, a fixed cylinder 7 is coaxially fixedly connected in the circular opening, the internal space of the fixed cylinder 7 is communicated with the bottom space of the support base 5, a carrying turntable 10 is coaxially connected to the fixed cylinder 7, the carrying turntable 10 is used to carry the ceramic workpiece, and the ceramic workpiece can be a ceramic pipe of different sizes, a rotating mechanism 9 is provided inside the isolation box 1 for driving the carrying turntable 10 to rotate, the rotating mechanism 9 includes a third motor 901 fixedly provided inside the isolation box 1, the output end of the third motor 901 is fixedly connected to a driving wheel 902 that cooperates with the carrying turntable 10, the third motor 901 starts and drives the driving wheel 902 to rotate, the driving wheel 902 drives the carrying turntable 10 to rotate, and the carrying turntable 10 drives the ceramic workpiece to rotate, thereby facilitating the glaze spraying operation on the ceramic workpiece.

[0024] A first moving component 2 is provided inside the isolation box 1, and the first moving component 2 includes a first motor 201 fixedly connected to the isolation box 1, and the output end of the first motor 201 is coaxially fixedly connected to a threaded rod 202, and the threaded rod 202 is threadedly connected to a side spraying nozzle 3. The side spraying nozzle 3 is responsible for spraying glaze on the outside of the ceramic workpiece. A first limiting component for limiting and guiding the side spraying nozzle 3 is provided inside the isolation box 1. The first motor 201 is started to drive the threaded rod 202 to rotate, and at the same time, the side spraying nozzle 3 is started, and the threaded rod 202 drives the side spraying nozzle 3 to move from bottom to top. At the same time, the ceramic workpiece rotates under the action of the supporting turntable 10, so as to facilitate the side spraying nozzle 3 to spray glaze on the outside of the ceramic workpiece, ensuring that the sides of the ceramic workpiece are covered with glazing liquid. The first limiting component can ensure the stability of the side spraying nozzle 3 during movement.

[0025] The first limiting assembly includes a guide rod 203 fixedly connected to the inside of the isolation box 1, and a positioning ring slidingly engaged with the guide rod 203 is fixedly connected to the side spraying nozzle 3. During the upward movement of the side spraying nozzle 3, the guide rod 203 will limit the side spraying nozzle 3, thereby ensuring the stability of the side spraying nozzle 3 during the upward movement.

[0026] In order to realize glaze spraying on the interior of the ceramic workpiece, the second moving component 4 includes a second motor 401 fixedly connected to the isolation box 1, and the output end of the second motor 401 is coaxially fixedly connected to the winding wheel 402, and a pull rope 403 is fixedly wound on the winding wheel 402. The pull rope 403 is connected to the internal spray nozzle 12 at one end away from the winding wheel 402. Initially, the internal spray nozzle 12 is located at the lower end of the ceramic workpiece. After the second motor 401 is started, it will drive the winding wheel 402 to rotate, and the winding wheel 402 drives the pull rope 403 to move, and the pull rope 403 drives the internal spray nozzle 12 to move upward, so that the internal spray nozzle 12 can act on various parts of the inner wall of the ceramic workpiece, thereby ensuring the spraying effect. A second limiting component for limiting and guiding the internal spray nozzle 12 is provided inside the isolation box 1. The second limiting component ensures that the internal spray nozzle 12 can move in the vertical direction to avoid the internal spray nozzle 12 colliding with the inner wall of the ceramic workpiece and causing damage to the internal spray nozzle 12 or the glaze layer.

[0027] The second limiting component includes a guide wire 404 fixedly connected to the top of the isolation box 1, the internal spray nozzle 12 slides on the guide wire 404, the suspension rod 8 is fixedly connected to the inside of the fixed cylinder 7, the lower end of the guide wire 404 is connected to the hook 405 that is engaged with the suspension rod 8, and the suspension rod 8 is provided with a hanging ring that cooperates with the hook 405. After the ceramic workpiece is placed, the guide wire 404 is put into the ceramic workpiece, and the hook 405 passing through the ceramic workpiece is engaged with the hanging ring on the suspension rod 8 through the circular opening on the support plate 6, thereby fixing the lower end of the guide wire 404, thereby maintaining the vertical state of the guide wire 404, and ensuring that the internal spray nozzle 12 can move vertically along the guide wire 404.

[0028] A glaze liquid output device 11 is provided inside the isolation box 1 , and the internal spray nozzle 12 and the side spray nozzle 3 are both connected to the output end of the glaze liquid output device 11 through a hose.

[0029] The side spray nozzle 3 and the internal spray nozzle 12 can be used separately. The horizontal height of the top of the fixed cylinder 7 needs to be slightly smaller than the horizontal height of the upper surface of the carrying turntable 10. That is, when the ceramic workpiece is not a ceramic pipe, but other ceramic components with a relatively flat bottom, such as a ceramic pump, a ceramic crucible, a ceramic reactor, etc., since the horizontal height of the top of the fixed cylinder 7 needs to be slightly smaller than the horizontal height of the upper surface of the carrying turntable 10, when in use, the carrying turntable 10 can still drive the ceramic component to rotate, and the fixed cylinder 7 will not rub the bottom of the ceramic component. At this time, when spraying glaze, only the second movable component 4 and the internal spray nozzle 12 need to be removed, and the operation can be completed only by the first movable component 2 and the side spray nozzle 3 to realize the glaze spraying operation on the ceramic workpiece.

[0030] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of the embodiments of this solution will now be described in conjunction with specific application scenarios:

[0031] During use, when the ceramic workpiece is a ceramic pipe, the ceramic workpiece can be placed vertically on the carrying turntable 10 first, and the guide wire 404 can be put into the ceramic workpiece. The upper end of the guide wire 404 is fixed to the top of the isolation box 1, and the hook 405 passing through the ceramic workpiece is clamped to the suspension rod 8 through the circular opening on the support plate 6, thereby fixing the state of the guide wire 404, adjusting the internal spray nozzle 12 and the side spray nozzle 3 to the bottom of the ceramic workpiece, and then starting the third motor 901. The third motor 901 drives the driving wheel 902 to rotate, and the driving wheel 902 drives the carrying turntable 10 to rotate, and the carrying turntable 10 drives the ceramic workpiece to rotate;

[0032] Start the first motor 201, which drives the threaded rod 202 to rotate. At the same time, start the side spraying nozzle 3. The rotation of the threaded rod 202 will drive the side spraying nozzle 3 to move along the guide rod 203. At the same time, the ceramic workpiece rotates under the action of the supporting turntable 10, thereby facilitating the side spraying nozzle 3 to spray glaze on various parts of the outer wall of the ceramic workpiece.

[0033] Start the second motor 401, the second motor 401 will drive the winding wheel 402 to rotate, the winding wheel 402 drives the pull rope 403 to move, and the pull rope 403 drives the internal spray nozzle 12 to move upward along the guide line 404. At the same time, in conjunction with the automatic rotation of the ceramic workpiece, the internal spray nozzle 12 can act on various parts of the inner wall of the ceramic workpiece, thereby ensuring the spraying effect. When in use, the guide line 404 can ensure that the internal spray nozzle 12 can move upward in a straight line, avoiding the internal spray nozzle 12 from colliding with the inner wall of the ceramic workpiece and causing damage to the internal spray nozzle 12 or the glaze layer;

[0034] During the glazing process, the ceramic workpiece rotates automatically under the action of the supporting turntable 10, and the side spraying nozzles 3 and the side spraying nozzles 3 can operate continuously along the vertical direction of the ceramic workpiece. By controlling the start and stop timing of the first motor 201 and the second motor 401, the device can spray glaze on ceramic workpieces of different heights. At the same time, the side spraying nozzles 3 and the side spraying nozzles 3 spray glaze on the outside and inside of the ceramic workpiece respectively, thereby improving the glazing efficiency of the ceramic workpiece; when the ceramic workpiece is not a ceramic pipe, but other ceramic components with a relatively flat bottom, such as a ceramic pump, a ceramic crucible, a ceramic reactor, etc., since the horizontal height of the top of the fixed cylinder 7 needs to be slightly lower than the horizontal height of the upper surface of the supporting turntable 10, when in use, the supporting turntable 10 can still drive the ceramic component to rotate, and the fixed cylinder 7 will not rub the bottom of the ceramic component. At this time, when spraying glaze, only the second movable assembly 4 and the internal spraying nozzle 12 need to be removed, and the operation can be completed only by the first movable assembly 2 and the side spraying nozzle 3 to realize the glazing operation on the ceramic workpiece.

However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
