Description

Technical Field

[0001] The invention relates to the technical field of porcelain production, in particular to a buoyancy type porcelain blank opening height compensation glazing device. Background Art

[0002] In the daily-use ceramics industry, the glazing process is performed manually. Due to the harsh working environment and high workload, most employees are reluctant to do this dirty, difficult, and tiring job. Furthermore, long-term exposure to this work, coupled with the inhalation of glaze vapors, can be harmful to the workers' health. Consequently, fewer and fewer people are now engaged in this work, and the industry is facing a serious worker shortage. Therefore, the gradual emergence of automatic glazing equipment on the market should gradually solve this problem.

[0003] There are several methods for applying glaze to porcelain blanks: dipping, spraying, pouring, and brushing. Brushing results in uneven glaze on the surface and poor surface gloss, so it is generally not used. Spraying, pouring, and brushing also result in uneven glaze on the surface, but are much better than brushing. Dipping provides the most uniform glaze and the best gloss, but its applicability is greatly restricted by the shape of the porcelain blank. Currently, most manufacturers use a combination of dipping and spraying methods, i.e., spraying and pouring glaze are used for inner glaze, and dipping is used for outer glaze. Automatic glazing equipment also uses this method.

[0004] In actual production, during the forming and drying process, due to differences in the particle size and density of the clay, the moisture content during forming and drying (approximately 5% difference), and the molds used to form the porcelain blanks, each blank in the same batch shrinks at a different rate, resulting in variations in blank height. Numerous porcelain factory users have reported this height deviation (±1.0mm), and while this deviation is unavoidable in the production process, the only solution is to address it through improved production equipment.

[0005] The automatic glazing equipment currently available does not have such a positioning device that compensates for the height difference (such as Figure 1 When applying the outer glaze using the dipping method, although the glaze can be applied to the clay during glazing, the automatic glazing system cannot quickly compensate for the ±1.0mm height difference. Some products may not be glazed at the mouth during glazing, significantly impacting the automatic glazing effect. Currently, porcelain factories rely on manual inspection and glazing of each product, which is labor-intensive and inefficient. Summary of the Invention

[0006] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0007] A buoyancy-type porcelain blank height compensation glazing device includes a mounting seat, a fixed shaft sleeve is fixedly installed on the top of the mounting seat, a rotating shaft that rotates with the fixed shaft sleeve is installed in the fixed shaft sleeve, the bottom end of the rotating shaft passes through the mounting seat and is fixedly connected to a sleeve, an air pipe that extends through the central axis of the rotating shaft is provided in the rotating shaft, a telescopic sleeve is fixedly connected to the bottom of the sleeve, a telescopic tube that slides with the rotating shaft is installed in the telescopic sleeve, a hose is connected between the top of the telescopic tube and the air pipe of the rotating shaft, a vacuum suction cup connected to the air path of the telescopic tube is fixedly installed on the bottom end of the telescopic tube, an adjustable height limiting rod is installed on the outer wall of the telescopic sleeve, a driving motor that drives the rotating shaft to rotate is also fixedly installed on the top of the mounting seat, and a rotating air nozzle connected to the air pipe is installed on the top of the rotating shaft.

[0008] Furthermore, a pair of clamping blocks threadedly matched with the telescopic sleeve are provided on the outer wall of the telescopic sleeve, and the height limiting rod is arranged between the pair of clamping blocks and is clamped and fixed.

[0009] Furthermore, a synchronous wheel arranged in a mounting seat is coaxially fixed on the rotating shaft, and a synchronous belt is connected between the rotating shaft of the drive motor and the synchronous wheel.

[0011] Furthermore, a lifting cylinder is provided on the rear side of the mounting seat, a connecting plate is fixedly installed on the top of the rear side of the mounting seat, and the telescopic rod of the lifting cylinder is hinged to the top end of the connecting plate.

[0012] Furthermore, the cylinder body of the lifting cylinder is tilted upward at 30 degrees to the horizontal plane.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention has a novel structure and utilizes the buoyancy of the glaze water to locate the height of the porcelain blank mouth. When the product is immersed in the glaze pool, the product is subjected to upward buoyancy. By adjusting the position of the height limit rod to fix the height of all porcelain blank mouths, it is ensured that the cup mouth of the product is level in the glaze pool, eliminating the influence caused by height error.
