Embossing device applied to intermediate film of organic polymer for laminated glass

Abstract

The invention discloses an embossing device applied to an intermediate film of an organic polymer for a laminated glass. The embossing device comprises a first embossing base, a first embossing mechanism, a cooling base, a cooling mechanism, a second embossing mechanism and a second embossing base, wherein the first embossing base is fixedly connected with the first embossing mechanism, the rightside of the first embossing base is provided with the cooling base, the cooling base is fixedly connected with the cooling mechanism, and the second embossing base is arranged on the right side of thecooling base. According to the embossing device applied to the intermediate film of the organic polymer for the laminated glass, a first pattern roller, a second pattern roller, a first rubber rollerand a second rubber roller are arranged and can be applied to the embossing device of the organic polymer intermediate film for laminated glass, heating and embossing are carried out in a mode of instantaneously contacting the pattern roller, the intermediate film is guaranteed to have sufficient peel strength, continuous embossing is carried out, the intermediate film cannot be polluted, an elastic yielding material can be utilized to compensate for the slight thickness difference in the transverse direction of the intermediate film, and the uniform and consistent pattern is pressed out.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to an embossing device applied to an organic polymer interlayer film for laminated glass. Background technique [0002] As a kind of safety glass, after the laminated glass is broken by impact, due to the bonding effect of the ordinary glass intermediate film, it will not produce sharp fragments to hurt people like ordinary glass after it is broken. Laminated glass will play a huge role in the safe use of glass. One or more layers of organic polymer interlayer films are sandwiched between two or more pieces of glass. After special high-temperature pre-pressure exhaust (or vacuum exhaust) and high-temperature and high-pressure processes, the glass and the interlayer film are permanently bonded. All-in-one composite glass product. [0003] Commonly used organic polymer interlayers for laminated glass include: PVB, SGP, EVA, PU, ​​etc. [0004] In the laminated glass manu...

Problems solved by technology

Patent CN103379999A, direct embossing system, method and device for polymer melt sheet, directly embossing high temperature melt see figure 1 , although the above problems are partially solved, there are four problems: 1. Due to the use of two steel rollers for pressing, the sheet coming out of the die will always have a thickness difference in the transverse direction no matter how it is adjusted, and patterns will be produced during the embossing process Inconsistent shades

3. Part of the lubricant is transferred to the surface of the intermediate film and the lubricant will be transferred soon, resulting in the need to reapply the lubricant, resulting in uncontinuous production

4. Although continuous production can be achieved through continuous coating of lubricants, the problem of contamination of the intermediate film caused by lubricants cannot be avoided
