Description

Technical Field

[0001] The present invention belongs to the technical field of ceramic production equipment, and particularly relates to a glaze removing device. Background Art

[0002] In the production process of ceramic products, it is necessary to glaze the green body. Whether glazing is carried out by machine or by hand, during the glazing process, glaze will adhere to the bottom surface of the ceramic product. After glazing is completed, it is necessary to remove the glaze on the bottom surface of the ceramic product. Otherwise, the existing glaze will adhere to the carbon silicon plate after sintering, and it is easy to have notches or broken feet when separating the product from the carbon silicon plate; currently, the commonly used method is manual glaze removal, and tools such as scrapers are used to effectively remove it. It requires a lot of labor, has a large labor intensity, and has a low production efficiency; therefore, it is very necessary to provide a glaze removing device with reasonable structural design, time-saving and labor-saving, and high working efficiency. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a glaze removing device with reasonable structural design, time-saving and labor-saving, and high working efficiency.

[0004] The purpose of the present invention is achieved as follows: A glaze removing device, which includes a box body. A support frame is arranged on the bottom surface inside the box body. A support shaft is arranged at the center of the support frame. A sleeve is sleeved outside the support shaft. The sleeve is rotatably connected to the support shaft. The top end of the sleeve is connected with a turntable. A groove is arranged at the center of the upper surface of the turntable. A support chassis is rotatably connected in the groove. The lower surface of the support chassis is fixedly connected to the top end of the support shaft. A friction pad is arranged around the groove on the upper surface of the turntable. A driven gear is fixed at a position near the bottom end of the sleeve. A driving gear is meshed with the driven gear. The driving gear is arranged on the output shaft of the motor. A clamping disc is arranged directly above the support chassis inside the box body. The upper surface of the clamping disc is connected to the top surface of the box body through an adjusting mechanism A.

[0005] The adjusting mechanism A includes an adjusting screw A rotatably connected to a mounting frame fixed on the top surface of the box body. The adjusting screw A is threadedly connected to a threaded hole A at the center of a sliding shaft. The sliding shaft is slidably connected to the box body. By rotating the adjusting screw A manually or electrically, the sliding shaft and the clamping disc connected to the sliding shaft can be pushed to move vertically upward or downward along the axial direction of the adjusting screw A, so as to clamp or loosen the porcelain on the support chassis.

[0006] The outer side surface of the sliding shaft adopts a regular polygon structure, and a through hole that matches the cross-sectional shape of the outer side surface of the sliding shaft is provided at the center position of the top surface of the box body to prevent the sliding shaft from rotating relative to the top surface of the box body and ensure the up and down movement of the clamping disc.

[0007] The bottom end of the support shaft is connected to the bottom surface of the box body through adjusting mechanism B. Through adjusting mechanism B, the relative height between the upper surface of the support chassis and the upper surface of the turntable can be adjusted to facilitate the removal of residual glaze from porcelain wares with different bottom shapes.

[0008] The adjusting mechanism B includes an adjusting screw B rotatably connected to the center position of the bottom surface of the box body. The top end of the adjusting screw B is connected to the threaded hole B at the center of the support shaft through a thread. A guide plate is fixed at a position near the bottom end on the outer side surface of the support shaft. A guide shaft is slidably connected to the guide plate, and the bottom end of the guide shaft is fixed to the bottom surface inside the box body. By rotating the adjusting screw B, the support shaft and the support chassis can be driven to move vertically upward or downward along the axial direction of the support shaft, so as to achieve the purpose of adjusting the height of the support chassis relative to the turntable.

[0009] The friction pad is composed of friction strips evenly distributed on the upper surface of the turntable, and the extension line of the friction strip intersects with the rotation center line of the turntable. During the rotation of the turntable, the movement direction of any point on the friction strip is basically perpendicular to the axis direction of the friction strip itself, ensuring the removal effect of the residual glaze on the bottom surface of the porcelain by the friction strip.

[0010] The friction strip includes a sponge strip and elastic rubber sheets fixed on both sides of the sponge strip. The bottom surfaces of the sponge strip and the elastic rubber sheets are fixedly connected to the upper surface of the turntable. During the relative rotation of the turntable and the porcelain, the elastic rubber sheets can scrape the residual glaze on the bottom surface of the porcelain, and the sponge strip between the elastic rubber sheets can wipe the bottom surface of the porcelain, thus ensuring the removal effect of the residual glaze.

[0011] Buffer pads are respectively fixed on the upper surface of the support chassis and the lower surface of the clamping disc to protect the porcelain fixed between the support chassis and the clamping disc.

[0012] The beneficial effects of the present invention:

[0013] 1. When the present invention is in use, the motor drives the turntable and the friction pad to rotate relative to the support chassis fixing the porcelain through gear transmission. The residual glaze on the bottom surface of the porcelain is removed through the relative movement between the friction pad and the bottom surface of the porcelain. During the removal of the residual glaze, there is no need to manually turn the porcelain and manually remove the residual glaze on the bottom surface of the porcelain. Compared with the prior art, it is not only time-saving and labor-saving, with high work efficiency, but also can greatly reduce the collision damage of the porcelain.

[0014] 2. In the present invention, the friction pad is composed of friction strips uniformly distributed on the upper surface of the turntable, and the extension lines of the friction strips intersect with the rotation center line of the turntable. The friction strip includes a sponge strip and elastic rubber sheets fixed on both sides of the sponge strip. The bottom surfaces of the sponge strip and the elastic rubber sheets are fixedly connected to the upper surface of the turntable. During the rotation of the turntable relative to the porcelain, the elastic rubber sheets can scrape off the remaining glaze on the bottom surface of the porcelain, and the sponge strip between the elastic rubber sheets can wipe the bottom surface of the porcelain, with good effect of removing the remaining glaze.

[0015] 3. In the present invention, the relative height between the upper surface of the support chassis and the upper surface of the turntable can be adjusted through the adjustment mechanism B, so as to facilitate the removal of the remaining glaze from porcelains with different bottom shapes, and it has strong versatility.
