A kind of equipment for the splicing process of SGP film and the splicing process of SGP film

Abstract

The invention relates to equipment for an SGP adhesive piece splicing process and the SGP adhesive piece splicing process. The equipment comprises a worktable which is used for supporting SGP adhesive pieces and a splicing device which is used for welding the SGP adhesive pieces; the splicing device is positioned above the workable and can move reciprocally up and down or back and forth. The splicing equipment provided by the invention can meet the requirement on performing large-specification laminated glass production on two or more than two SGP adhesive pieces; the production efficiency is high; a machined product does not have the defects, such as laminated air bubbles and the like.

Description

technical field [0001] The invention relates to the technical field of SGP films, in particular to a device for the splicing process of the SGP films and the splicing process of the SGP films. Background technique [0002] Laminated glass is composed of two or more pieces of glass and one or more layers of organic polymer intermediate film sandwiched between the glass. The films are permanently bonded together to form a composite glass product. SGP film is a new type of interlayer film for laminated glass. Compared with the commonly used PVB film, it has higher tear strength and adhesion, and is more expensive. Due to the excellent characteristics of laminated glass with SGP film as the interlayer film, it is currently widely used in glass curtain walls, open-air ceilings, cash transport vehicles, banks, prisons and other places. [0003] However, the following two problems will be encountered in the production of SGP laminated glass: First, due to the limitations of the S...

AI Technical Summary

Problems solved by technology

[0003] However, the following two problems will be encountered in the production of SGP laminated glass: First, due to the limitations of the SGP material in its own manufacturing process and transportation conditions, the finished product size cannot be too large. When it is necessary to produce large-format SGP laminated glass, At present, manufacturers usually put together two or more pieces of SGP films in the middle of every two pieces of large-format glass, then fix them with high-temperature-resistant tape, and make large-format laminated glass through pre-pressing and steam curing processes. , the efficiency of this process is low; secondly, the SGP film is expensive, and a lot of SGP trims are inevitably left in the traditional production process, which is difficult to make full use of, resulting in material waste and increased production costs. The production of large-sized SGP laminated glass in a fixed way will not only increase the production cost due to too many joints, but also cause obvious bubble marks inside the produced SGP laminated glass (at the joint of two SGP films)

[0004] At present, the method of using the above-mentioned high-temperature-resistant tape fixing process to solve the production of large-size SGP laminated glass is not only low in production efficiency and high in cost, but also increases the risk of air bubbles in the product; moreover, the current international production technology development of SGP film splicing technology is in line with It is basically the same in China, therefore, the production process of the existing SGP film splicing technology needs to be further improved
