Through the setting of spraying box, through hole, conveyor frame, conveyor belt, guide wheel, cleaning mechanism, box cover, drive mechanism, spraying mechanism and controller, the antibacterial ceramic glaze spraying mechanism can improve spraying efficiency, prevent the bearing surface from contaminating the ceramic glaze, and adjust the spraying angle and range.

[0003] However, the rotating nozzle of this patent has a continuous relative displacement with the discharge pipe, which can easily cause stress concentration at the pipe connection when rotating at high speed, leading to the risk of fatigue fracture due to repeated bending of the pipe body. At the same time, the water-absorbing cotton roller cleaning method has an adsorption saturation threshold limitation. When the absorbed liquid reaches the critical value, the cleaning efficiency drops sharply, requiring frequent shutdowns to replace consumables, which seriously affects the efficiency of continuous operation.

[0021] Reference Figures 1 to 5In this embodiment of the present invention, a ceramic glaze spraying mechanism includes: a conveyor belt 1, the conveyor belt 1 being made of non-stick rubber, the annular belt being supported by rollers to form a horizontal conveying surface, a spraying chamber 2 made of metal plate being welded directly above the conveyor belt 1, a motor 3 being fixedly installed at the top center of the spraying chamber 2 by bolts, the drive shaft of the motor 3 being vertically downward through the sealed upper cover plate of the spraying chamber 2, and being rigidly connected to the top center of the glaze tank 4 by a coupling, the glaze tank 4 being a cylindrical stainless steel container, the bottom of which is welded with a circular bottom plate 5, the center of the bottom plate 5 being fixedly connected to the upper end of a rotating rod 6 by a flange, the lower end of the rotating rod 6 extending into the internal space of the spraying chamber 2, and being coaxially connected to a connecting plate 7 by a keyway.

[0022] The connecting plate 7 has a connecting frame 8 welded to the ends of its two arms. The connecting frame 8 is a telescopic aluminum alloy rod, and the end is fixed to an electric movable seat 9 by bolts. A nozzle 10 is installed on the rotating shaft of the electric movable seat 9. The feed port of the nozzle 10 is connected to the feed pipe 11 through a high-pressure hose. The upper end of the feed pipe 11 is connected to the discharge port at the bottom of the glaze tank 4 in the form of a rotary joint. The side of the glaze tank 4 is provided with a replenishment pipe 12, the feed end of which is connected to an external feeding system through a quick connector to realize continuous replenishment of glaze.

[0023] A water collection tank 13 is set below the unloading end of the conveyor belt 1. The water collection tank 13 is a rectangular stainless steel tank with a vertical support 14 welded to the bottom of its inner side. An adjustable angle water sprayer 15 is installed on the top of the support 14. The water sprayer 15 is connected to the outlet of the water pump 16 through a water pipe. The inlet of the water pump 16 is connected to an external water storage tank through a hose. Two sets of support seats 17 are symmetrically installed on the outside of the water collection tank 13. A cleaning roller 18 is installed in each support seat 17 through a bearing. The surface of the cleaning roller 18 is covered with a cleaning brush made of nylon material. Its axis is perpendicular to the running direction of the conveyor belt 1. The contact pressure between the brush tip and the bottom surface of the conveyor belt 1 is adjustable.

[0024] A base plate 19 is welded below the feeding end of the conveyor belt 1. A drive seat 20 is fixed to the center of the base plate 19 by bolts. The output shaft of the drive seat 20 is vertically connected to the rotating shaft of the fan 21. A fixing frame 22 is welded at the four corners of the base plate 19. A protective net 23 is laid on the top of the fixing frame 22. The protective net 23 is constructed of stainless steel isolation rods. Multiple vertical isolation rods are welded at equal intervals on its inner side. The spacing between the isolation rods is less than one-third of the diameter of the fan blades 21, forming a directional airflow channel.

[0025] The working principle of this utility model is as follows:

[0026] When the conveyor belt 1 starts to operate, the ceramic product to be sprayed moves into the working area of ​​the spraying chamber 2 at a constant speed along its surface. At this time, the motor 3 drives the glaze box 4 and the rotating rod 6 to rotate synchronously, driving the connecting plate 7 to make a circular motion. The connecting frames 8 symmetrically distributed on both sides of the connecting plate 7 unfold under the action of centrifugal force. The electric movable seat 9 adjusts the pitch angle of the nozzle 10 according to the preset program, so that when the glaze in the glaze box 4 is transported to the nozzle 10 through the conveying pipe 11, it can form a three-dimensional cross-shaped atomized coverage in the rotation trajectory.

[0027] The feeding pipe 12 continuously replenishes glaze to the glaze tank 4, maintaining a constant supply pressure. Under the coordinated action of the rotation of the connecting frame 8 and the angle adjustment of the electric movable seat 9, the nozzle 10 performs multi-dimensional spraying on the ceramic products passing through the spraying chamber 2. The design of the feeding pipe 11 rotating synchronously with the glaze tank 4 effectively avoids the twisting and stretching of the pipe body during movement.

[0028] When the coated product moves to the unloading end with the conveyor belt 1, the water sprayer 15 in the water collection tank 13 obtains water through the water pump 16 to reverse rinse the surface of the conveyor belt 1, removing residual glaze particles. The cleaning brush on the surface of the cleaning roller 18 performs secondary cleaning when the conveyor belt 1 returns, peeling off the cured glaze adhering to the belt surface. In the feeding end area, the drive seat 20 drives the fan 21 to generate directional airflow, which forms a laminar flow air curtain through the isolation rod of the protective net 23 to dry the water stains remaining on the conveyor belt 1.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
