Description

Technical Field

[0001] This utility model belongs to the field of ceramic product manufacturing technology, specifically an automatic glazing machine for the production of daily-use ceramic products. Background Technology

[0002] Ceramics are made from clay and other raw materials, through shaping and firing, and encompass tableware, decorative items, and more. Glazing allows for a uniform glaze layer, improves surface smoothness and sealing, prevents leakage, protects the ceramic body, enhances aesthetics, and extends lifespan.

[0003] However, traditional glazing machines require manual placement of ceramic products into the glaze cylinder, and manual removal of the ceramic products after glazing is completed. This reliance on manual operation, coupled with the fact that glazing time depends on worker experience, not only results in high labor costs and low production efficiency, but also makes it easy for the green body to break due to uneven force and time deviation. Furthermore, most glazing machines are usually stationary during the glazing process, which can lead to problems such as localized glaze accumulation, thin glaze, and residual bubbles. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides an automatic glazing machine for the production of daily-use ceramic products, which solves the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic glazing machine for the production of daily-use ceramic products, comprising a glazing frame, a base fixedly connected to the bottom of the glazing frame, a glaze cylinder fixedly connected to the upper end of the base, a feeding machine and a discharging machine respectively arranged on both sides of the glazing frame, a transmission chamber fixedly connected to the top of the glazing frame, a motor platform fixedly connected to the outer wall of the transmission chamber, two servo motors fixedly mounted on the motor platform, the output shaft of the servo motor passing through the transmission chamber and coaxially fixedly connected to a worm gear, a worm wheel arranged inside the transmission chamber, and a strip groove opened at the bottom of the transmission chamber.

[0006] As a further embodiment of this utility model: the strip groove extends along the axial direction of the worm gear, and the length of the strip groove is not less than the horizontal distance between the feeder and the unfeeder. The width of the strip groove is slightly larger than the diameter of the worm gear output shaft to accommodate the sliding of the worm gear output shaft.

[0007] As a further embodiment of this utility model: the two worms are symmetrically distributed on both sides of the worm wheel with the axis of the worm wheel as the center of symmetry, and the worm wheel and the worms on both sides maintain meshing transmission.

[0008] As a further embodiment of this utility model, the two servo motors are linked and controlled by a synchronous controller.

[0009] As a further embodiment of this utility model: the output shaft of the worm gear passes vertically downward through the strip groove and its bottom end is provided with an adsorption mechanism for gripping ceramic products.

[0010] As a further embodiment of this utility model: the adsorption mechanism includes an electric cylinder coaxially fixedly connected to the bottom end of the worm gear output shaft, the output end of the electric cylinder is fixedly connected to a mounting plate, four negative pressure pumps are embedded on the mounting plate, the suction end of the negative pressure pump is connected to a suction pipe, and the bottom of the suction pipe is connected to a suction cup.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: Driven by a servo motor, two worm gears rotate in the same direction, causing the meshing worm wheel to move stably along the path between the feeder and the unloader. With the adsorption mechanism at the bottom of the worm wheel output shaft, the entire process of picking up, glazing, and unloading ceramic products can be completed automatically without human intervention. This not only significantly reduces labor costs but also allows for precise control of the glazing time for each group of products through programming. This effectively avoids damage to the green body or glaze defects caused by uneven force and time during manual operation, and significantly reduces the scrap rate.

[0012] By controlling two worm gears to rotate in opposite directions via a servo motor, the meshing worm wheel rotates synchronously, thereby driving the bottom adsorption mechanism and the ceramic product being gripped to rotate in the glaze. This effectively prevents problems such as local glaze accumulation, thin glaze, and residual bubbles that easily occur during static glazing, significantly improving the uniformity of glaze coverage and the sufficiency of glazing, and ensuring the glaze quality of ceramic products.

[0015] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0016] like Figure 1 - Figure 3 As shown, this utility model provides a technical solution: An automatic glazing machine for producing daily-use ceramic products includes a glazing frame 1, a base 2 fixedly connected to the bottom of the glazing frame 1, a glaze cylinder 3 fixedly connected to the upper end of the base 2, a feeding machine 4 and a discharging machine 5 respectively arranged on both sides of the glazing frame 1, a transmission chamber 6 fixedly connected to the top of the glazing frame 1, a motor platform 7 fixedly connected to the outer wall of the transmission chamber 6, two servo motors 8 fixedly installed on the motor platform 7, the output shaft of the servo motor 8 passes through the transmission chamber 6 and is coaxially fixedly connected to a worm gear 9, a worm wheel 10 is arranged inside the transmission chamber 6, and a strip groove 11 is opened at the bottom of the transmission chamber 6; Specifically, the glazing frame 1 and the base 2 constitute the main frame of the entire device, providing a stable installation foundation for the installation of each component. The feeding machine 4 can transport the ceramic products to be glazed to the underside of the adsorption mechanism in a rhythmic manner. The unloading machine 5 automatically receives the glazed green body and transfers it to the next process. Two servo motors 8 transmit power through the coaxial fixed connection between the output shaft and the worm 9. With the meshing transmission of the worm 9 and the worm wheel 10, stable power is provided for the worm wheel 10 to drive the adsorption mechanism to rotate along the axial direction of the worm 9 (realizing the position switching of the green body between the feeding machine 4, the glaze cylinder 3, and the unloading machine 5) and for the worm wheel 10 to drive the adsorption mechanism to rotate (realizing the rotational glazing of the green body in the glaze). The transmission chamber 6 serves as a protective structure to protect the meshing action of the worm wheel 10 and the worm 9, and to prevent transmission jamming or wear caused by glaze dripping or dust entering. The strip groove 11 extends along the axial direction of the worm 9, and the length of the strip groove 11 is not less than the horizontal distance between the feeder 4 and the unfeeder 5. The width of the strip groove 11 is slightly larger than the diameter of the output shaft of the worm wheel 10 to accommodate the sliding of the output shaft of the worm wheel 10. The two worms 9 are symmetrically distributed on both sides of the worm wheel 10 with the axis of the worm wheel 10 as the center of symmetry, and the worm wheel 10 and the worms 9 on both sides maintain meshing transmission. The two servo motors 8 achieve linkage control through a synchronous controller. The output shaft of the worm wheel 10 passes vertically downward through the strip groove 11 and its bottom end is provided with an adsorption mechanism for gripping ceramic products. Specifically, the two servo motors 8 are linked and controlled by a synchronous controller. When the servo motors 8 are running, they drive the corresponding worm gears 9 to rotate synchronously. Since the worm wheel 10 is engaged with the worm gears 9 on both sides, when the two worm gears 9 rotate in the same direction, the axial force generated by the meshing drives the worm wheel 10 to move horizontally along the extension direction of the strip groove 11, thereby driving the adsorption mechanism at the bottom of the output shaft to move precisely to the target working area (such as the loading position, glazing position, and unloading position). When the two worm gears 9 rotate in opposite directions, the circumferential force generated by the meshing drives the worm wheel 10 to rotate around its own axis, thereby driving the adsorption mechanism and the ceramic products it grabs to rotate in the glaze cylinder 3 containing the glaze liquid, ensuring uniform glaze coverage and effectively improving the glazing quality. The adsorption mechanism includes an electric cylinder 12 coaxially fixedly connected to the bottom end of the output shaft of the worm gear 10. The output end of the electric cylinder 12 is fixedly connected to a mounting plate 13. Four negative pressure pumps 14 are embedded on the mounting plate 13. The suction end of the negative pressure pump 14 is connected to a suction pipe 15. The bottom of the suction pipe 15 is connected to a suction cup 16. Specifically, when the worm gear 10 moves to the loading area, its output end drives the suction cup 16 to descend onto the ceramic product to be glazed. The negative pressure pump 14 is turned on, and the suction cup 16 firmly adheres to the ceramic product through the suction pipe 15. When the worm gear 10 moves above the glaze cylinder 3, the output end of the electric cylinder 12 descends to immerse the ceramic product in the glaze. At the same time, the two servo motors 8 drive the worm 9 to rotate in the opposite direction, causing the worm gear 10 to rotate, so that the ceramic product rotates in the glaze to ensure a uniform glaze layer. After glazing is completed, the output end of the electric cylinder 12 rises to remove the ceramic product from the glaze and drain excess glaze. Then, the worm gear 10 moves to the unloading area, the output end of the electric cylinder 12 descends, the negative pressure pump 14 is turned off, the suction cup 16 releases the ceramic product to the unloading machine 5, the electric cylinder 12 resets, and the worm gear 10 returns to the loading area to start the next round of operation.

[0017] The working principle of this utility model is as follows: First, the feeding machine 4 transports the ceramic products to be glazed to the area directly below the adsorption mechanism. The worm gear 10 is moved to the feeding area under the drive of the servo motor 8. Then, the electric cylinder 12 is started, and its output end drives the mounting plate 13 and the suction cup 16 to descend until the suction cup 16 adheres to the surface of the product. The negative pressure pump 14 is turned on, and the suction pipe 15 generates negative pressure in the suction cup 16, firmly adsorbing the products to be glazed. After adsorption is completed, the two servo motors 8 are linked and controlled by the synchronous controller. The two servo motors 8 drive the worm gear 9 to rotate in the same direction. Through meshing transmission, the worm wheel 10 is driven to move horizontally along the strip groove 11 until the product is precisely moved above the glaze cylinder 3. Then, the glazing process is carried out: the electric cylinder 12 starts again, the output end descends, and the adsorbed product is completely immersed in the glaze in the glaze cylinder 3; at the same time, the two servo motors 8 drive the worm gear 9 to rotate in the opposite direction, and through meshing transmission, drive the worm wheel 10 to rotate around its own axis, so that the product rotates synchronously in the glaze liquid, ensuring that the glaze layer is evenly covered. After the glazing is completed: the electric cylinder 12 returns to its original position and rises, causing the product to detach from the glaze and remain for a few seconds to drain excess glaze from the surface; then the servo motor 8 drives the worm gear 9 to rotate in the same direction, causing the worm wheel 10 and the drained product to move above the unloading machine 5. Finally, the electric cylinder 12 starts to descend, sending the product onto the conveyor belt of the unloading machine 5; the negative pressure pump 14 is turned off, and the suction cup 16 releases the product; the electric cylinder 12 resets and rises, and the worm gear 10 returns to the loading area under the drive of the servo motor 8, ready to enter the next round of glazing process.

[0018] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
