Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive supply technology, and in particular to a voltage stabilizing component for an automatic glue applicator. Background Technology

[0002] Thermoplastic spacers (TPS) eliminate the use of heat-conducting metals like aluminum and stainless steel in traditional insulated glass. Insulated glass made with TPS has a significantly lower linear thermal conductivity than traditional products, effectively blocking heat loss from the glass edges and thus improving the overall energy efficiency of the window. TPS insulated glass has a lifespan 2-3 times longer than ordinary insulated glass and offers superior warm-edge performance. It provides a very low edge U-value, minimizing condensation at the edges. Due to its excellent performance, TPS insulated glass is used in passive house construction. TPS insulated glass features include: TPS thermoplastic spacers without metal embeddings; improved thermal barrier properties at the glass edges; a more even surface temperature distribution on both the inner and outer surfaces; effective reduction of condensation at the glass edges, inhibiting mold growth; flexible edge sealing; product diversity, making glass design more flexible and convenient; perfect compatibility with the glass assembly industry; high quality control; and a longer effective lifespan.

[0003] In TPS glue application production, glue is supplied to the glue application head through a glue supply mechanism. In addition to the high requirements for continuous glue supply, the stability of glue supply is also required. However, existing glue application mechanisms generally use 5-6 meter long pipes to transport glue to the glue application head, which can easily lead to problems such as unstable pressure. If these problems are not solved, they will affect the quality of the spacer strip formed, which may result in poor sealing and air leakage in the produced insulating glass.

[0004] For example, patent document CN202420834101.8 discloses a TPSS glue supply and pressure stabilization mechanism, which includes a glue supply connector connected between a glue supply tube and a dispensing head. A pressure sensor is installed at the end of the glue supply channel. A glue cylinder is connected to the glue supply connector. The glue cylinder is connected to an inverted cylinder via a first positioning frame. The glue cylinder includes a cylinder body fixed to the glue supply connector, a heating coil outside the cylinder body, and a glue piston inside the cylinder body to form a glue storage cavity communicating with the glue supply channel below it, and a glue piston rod connected above it. The air piston rod of the cylinder is fixed to the upper end of the glue piston rod via a connector. An electronic ruler is installed on the side of the cylinder body, and an electronic ruler end plate is connected to the side of the connector. The floating connector of the electronic ruler is connected to the electronic ruler end plate to measure the amount of glue entering the glue storage cavity. This TPSS glue supply and pressure stabilization mechanism can replenish glue in time to achieve a stable glue supply to the dispensing head when the glue delivered by the glue supply tube experiences pressure or flow loss.

[0005] However, the above technical solutions still have shortcomings. If there is a continuous pressure loss or flow loss in the glue supply pipe, and the glue in the glue cylinder is continuously output without being replenished in time, it will eventually affect the glue application quality.
