Description

Technical Field

[0001] The utility model relates to the technical field of glass manufacturing, in particular to a glass clamp with variable size. Background Art

[0002] Organic glass is a popular name, abbreviated as PMMA. The chemical name of this polymer transparent material is polymethyl methacrylate, which is a polymer compound formed by the polymerization of methyl methacrylate. It is an important thermoplastic plastic that was developed earlier. Organic glass is divided into four types: colorless transparent, colored transparent, pearlescent, and embossed organic glass. Organic glass is commonly known as acrylic, Zhongxuan acrylic, and acrylic. Organic glass has good transparency, chemical stability, mechanical properties and weather resistance, easy dyeing, easy processing, and beautiful appearance.

[0003] At present, when producing organic glass, it is necessary to coat the glass before the glass leaves the factory. The existing coating method usually requires clamping and fixing the glass first, and then coating. However, the existing glass clamping facilities use a rigid clamping method to clamp the glass when positioning it. When clamping glasses of different sizes, the clamping force cannot be well controlled. When the clamping force is too large, the glass is easily damaged. Utility Model Content
