Arc-shaped chemically-toughened glass surface sand blasting device and implementation method thereof

Abstract

The invention discloses an arc-shaped chemically-toughened glass surface sand blasting device which comprises a guide base, a waste receiving assembly, a surface sand blasting mechanism and an external hopper. The waste receiving assembly is installed in the center of the bottom of the guide base, the surface sand blasting mechanism is installed in the center of the upper side of the guide base, and a driving motor drives a guide roller to rotate to convey arc-shaped glass into the surface sand blasting mechanism. The heights of a hydraulic telescopic rod and a sand blasting head are adjustedthrough a hydraulic driving assembly, so that the sand blasting head is in contact with the surface of the arc-shaped glass, and raw material sand is poured into the external hopper, sequentially passes through the external hopper, a flow dividing pipe and a conveying pipe, enters an accumulation sleeve, and is sprayed to the surface of the arc-shaped glass through the sand blasting head; and a horizontal sliding block moves on a horizontal sliding rod, so that the raw material sand is evenly brushed through brushing fluff. The equipment can be freely compatible with arc-shaped glass productsof various different angles, the brushing time is short, and the working efficiency is high.

Description

technical field [0001] The invention relates to the technical field of chemically tempered glass, in particular to a sandblasting device for the surface of curved chemically tempered glass and an implementation method thereof. Background technique [0002] Chemically tempered glass is to place the glass in molten alkali salt, so that the ions in the surface of the glass are exchanged with the ions in the molten salt. Due to the volume change after the exchange, compressive stress is formed on both surfaces of the glass, and tensile stress is formed inside, so that To achieve the effect of improving the strength of the glass, the chemically tempered glass has high strength, good thermal stability, no deformation on the surface, can be properly cut, and has no self-explosion phenomenon. The chemically tempered glass is actually a kind of prestressed glass. In order to improve the strength of the glass, Usually chemical or physical methods are used to form compressive stress on...

[0002] Chemically tempered glass is to place the glass in molten alkali salt, so that the ions in the surface of the glass are exchanged with the ions in the molten salt. Due to the volume change after the exchange, compressive stress is formed on both surfaces of the glass, and tensile stress is formed inside, so that To achieve the effect of improving the strength of the glass, the chemically tempered glass has high strength, good thermal stability, no deformation on the surface, can be properly cut, and has no self-explosion phenomenon. The chemically tempered glass is actually a kind of prestressed glass. In order to improve the strength of the glass, Usually chemical or physical methods are used to form compressive stress on the surface of the glass. When the glass is subjected to external forces, the surface stress is first offset, thereby improving the bearing capacity and enhancing the glass's own wind pressure resistance, cold and heat resistance, impact resistance, etc. The main purpose of chemical tempered glass There are two advantages. The first is that the strength is several times higher than that of ordinary glass, the bending strength is 3-5 times that of ordinary glass, and the impact strength is 5-10 times that of ordinary glass. Increased strength also improves safety. The second main advantage of tempered glass is that it is safe to use, and its load-carrying capacity is increased to improve its fragility. The finished products of chemically tempered glass in the prior art usually need to be sandblasted on its surface to improve the overall appearance of tempered glass products degree, and increase the friction on its surface, while the glass sandblasting equipment in the prior art cannot cope with glass products with curved surfaces, and after sandblasting, it is necessary to manually paint the raw material sand evenly, and the process consumes a long time , sandblasting work efficiency is low
