Description

Technical Field

[0001] The utility model relates to the field of insulating glass glue production, in particular to a TPSS glue supply and voltage stabilizing mechanism. Background Art

[0002] Insulating glass is a new type of building material that has good heat insulation, sound insulation, is beautiful and practical, and can reduce the weight of buildings. The common insulating glass on the market is mostly formed by adding metal spacers between two or more pieces of glass to support the formation of a hollow layer, and two layers of gluing are used to ensure the sealing of the hollow layer. Although the metal spacers give the insulating glass a reasonable hollow layer thickness and service life, the metal spacers conduct heat too quickly, and when the temperature difference between indoors and outdoors convects, metal heat bridges will be formed, which significantly reduces the thermal insulation of the glass. Therefore, with the development of science and technology, based on factors such as energy consumption, TPSS thermoplastic warm edge spacers came into being.

[0003] In the gluing production of TPSS thermoplastic warm edge spacers, glue is supplied to the gluing head through a glue supply mechanism. In addition to the high requirements for the continuity of the glue supply, higher requirements are also placed on the stability of the glue supply. The existing gluing mechanism generally uses a 5-6 meter long pipe to transport the glue to the gluing head. Therefore, it is easy to cause problems such as unstable pressure. If not resolved, it will affect the quality of the spacers formed, and may cause the produced insulating glass to be poorly sealed and leak. Utility Model Content

[0007] The first positioning frame includes a lower positioning ring fixedly connected to the glue cylinder body and an upper positioning ring fixedly connected to the cylinder body of the cylinder. A plurality of positioning rods are connected between the upper positioning ring and the lower positioning ring. An electronic ruler is provided on the side of the cylinder body of the cylinder. An electronic ruler end plate is connected to the side of the connecting piece.

[0019] Working principle: Before glue is applied through the glue head, glue is first fed into the glue storage chamber 304.

When the electronic ruler 7 measures that the glue has been fed to a certain amount, the glue feeding stops and glue is supplied to the glue head for glue application.
