Description

Technical Field

[0001] The invention relates to the technical field of glass etching, in particular to an etching device for high-definition glass. Background Art

[0002] Etching is a process of engraving patterns or text on the surface of materials. By using chemical or physical means to remove the surface layer of a specific area, a visible design or pattern is formed. It has a wide range of applications. Etching processes can be divided into two categories: chemical etching and physical etching. Chemical etching has low cost and is applicable to a wide range of materials. It is the main choice for etching processing. Spray etching and immersion etching are the main etching methods, and spray etching is better than immersion etching. Glass etching refers to the use of hydrofluoric acid to corrode glass to form a pattern. Apply paraffin wax to the glass, then use tools to carve a pattern on the paraffin wax, and then apply hydrofluoric acid on it to get a glass etching pattern. In the current craze for decoration, glass, mirrors, and utensils engraved with various patterns and calligraphy fonts are very popular among consumers. Etching solution formula: 18.4% 50-60℃ hot water, 23.5% ammonium hydrofluoride, 12.4% oxalic acid, 15.7% ammonium sulfate, 6.5% glycerol, 23.5% barium sulfate, in addition, a little organic dye is added for proper color matching, the above ingredients are mixed and stirred evenly before etching, and an etching device for high-definition glass is provided when etching high-definition glass.

[0003] The following problems exist when performing high-definition glass etching:

[0004] Both sides of high-definition glass can be etched, but the steps of replacing the two sides during etching are troublesome, and the glass needs to be taken out for subsequent etching. High-definition glass is brittle, and improper replacement of the two sides can easily cause damage;

[0005] When processing high-definition glass, its size is different, so it is necessary to position and clamp the high-definition glass, but the flexibility during clamping is limited, and it is not convenient to clamp high-definition glass of different sizes;

[0006] The etching solution has a certain cost, so the etching solution needs to be recycled. When the etching solution is recycled, the residue left over from the last etching will be retained in it.

[0057] The lower end of the infusion hose 502 is provided with an injection port 505, and a solenoid valve is installed at the connection between the injection port 505 and the infusion hose 502. When the solenoid valve is opened, the etching liquid in the liquid collection box 501 is guided to the injection port 505 through the infusion hose 502 to etch the glass body 405.

[0058] In one of the embodiments, a winding motor 703 is provided on the side of the winding machine 701, and a winding shaft 702 is installed at the output end of the winding motor 703.

The connecting plate 504 at the corresponding position on the glass body 405 is pushed by the electric telescopic rod 503 to adjust its height, and the injection port 505 is placed at the upper end of the glass body 405. The solenoid valve is then opened to guide the etching liquid to the glass body 405, and the unetched side of the glass body 405 is etched. Similarly, the etching liquid is guided to the original liquid tank 202 through the lower liquid port 104 for subsequent purification treatment;

[0061] When replacing the filter 206, pull the handle 211 to make the rod 212 leave the socket 208, then separate the block 207 from the socket 2051, take out the new filter 206, engage the block 207 with the socket 2051, and release the rod 210 so that the spring 213 pushes the rod 212 into the socket 208, and the filter 206 is installed and limited.
