Description

Technical Field

[0001] The invention relates to the technical field of insulating glass manufacturing, in particular to a heating device for insulating glass thermoplastic spacer strips. Background Art

[0002] Modern buildings have higher and higher requirements for energy saving, and the quality and life of insulating glass are becoming more and more stringent. The qualification rate of insulating glass and the service life of the product have become the topic of industry competition, requiring the processing equipment of insulating glass to be more perfect. Thermoplastic spacers are an important part of insulating glass manufacturing. Compared with traditional aluminum thermoplastic spacers, thermoplastic spacers have better thermal insulation performance and can effectively reduce the heat conduction through thermoplastic spacers, thereby improving the overall thermal insulation effect of insulating glass. Thermoplastic spacers are usually processed by bending after heating and softening to adapt to the edge shape of insulating glass to achieve the purpose of sealing and supporting glass.

[0003] The production of insulating glass requires a constant temperature and humidity working environment. The glue that has just been applied needs to be cooled and shaped, otherwise the formed glue is easy to fall off or deform when the glass is running and shaking. Before pressing two pieces of glass into insulating glass, the glass needs to be quickly heated around to melt the surface of the glue slightly, so that it is easier to bond the glass during pressing. If the glue and glass are not firmly bonded, gaps are likely to occur at the bonding point, affecting the life and firmness of the insulating glass. The existing insulating glass thermoplastic spacer heating equipment cannot heat the thermoplastic spacers on the four sides of the insulating glass at the same time, and cannot be applied to insulating glass of different sizes.

Since one end of the first spring piece 607 is clamped with the first plug hole 609 on the first mounting substrate 606, and the other end of the first spring piece 607 passes through the first notch 610 and is clamped with the first notch 610 of the second rotating shaft 603, the first spring piece 607 on the first mounting substrate 606 in the first slide groove 608 of the first guide plate 604 is stretched open, as shown in FIG.
