Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive supply technology, and in particular to an adhesive supply 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 the production of TPS insulating glass, adhesive is supplied to an automatic glue applicator via a glue supply machine. Existing glue supply machines, such as the one disclosed in patent application CN202322275118.2, include a precision-positioning glue applicator comprising: a base and a control cabinet fixedly mounted at the top center of the base; a lifting mechanism located at the top of the base; and a pressure plate fixedly connected to the output end of the lifting mechanism above the glue tank, with a glue outlet channel at the center of the pressure plate. The control cabinet controls the lifting mechanism to move the pressure plate upwards, then places the glue tank below the pressure plate, opens the exhaust valve to release air, and simultaneously controls the lifting mechanism to move the pressure plate downwards, heating the pressure plate. The heated glue area is then controlled by the control cabinet to have a pushing cylinder drive a pushing piston to reciprocate, discharging the molten glue through a one-way glue inlet valve and a one-way glue outlet valve, achieving rapid and sufficient glue supply, effectively improving the uniformity of glue melting and the efficiency of glue supply.

[0004] The aforementioned glue supply component mainly dispenses glue through extrusion. If the extrusion force fluctuates during the extrusion process, the glue supply will be unstable. Due to the viscosity of the glue, the subsequent glue application quality is easily compromised. At the same time, since the glue pushing component is set on the pressure plate, the heating element can only be installed by embedding it, which makes subsequent maintenance inconvenient.
