[0032] The implementation principle of this utility model's PUR glue pot glue quantity control structure for panel furniture is as follows:
[0033] 1. Innovative application of materials: Utilizing high-temperature resistant PEEK materials.
[0034] PEEK material properties: Polyetheretherketone (PEEK) is a high-performance engineering plastic with excellent high temperature resistance (long-term service temperature up to 250℃), mechanical strength and chemical stability.
[0035] Application design: The valve core and the parts in contact with the adhesive of control valve 6 are made of PEEK material to ensure that they can maintain stable mechanical properties and sealing performance in high-temperature environments.
[0036] 2. Structural optimization: Cylinder 2 and adhesive temperature separation
[0037] Thermal insulation design: A thermal insulation layer is added between cylinder 2 and glue pot 1, using ceramic fiber or other high-efficiency thermal insulation materials to reduce heat transfer and ensure that cylinder 2 operates at normal temperature. As shown in the figure: Glue pot connecting plate 4 connects cylinder 2 and glue pot 1 with bolts, preventing the glue pot 1 from transferring high temperature to cylinder 2 and affecting its service life. Additionally, a thermal insulation plate 71 connects cylinder connecting plate 72 and ejector pin 5 with PEEK high-temperature resistant material, effectively preventing the glue temperature from being transferred to the valve core of cylinder 2 through ejector pin 5, thus preventing damage to the internal piston and sealing ring 83 of cylinder 2. This increases the service life of cylinder 2.
[0038] 3. Extended ejector pin 5: By designing an extended ejector pin 5, the cylinder 2 is installed at a position away from the glue pot 1, further reducing the working temperature of the cylinder 2.
[0039] Implementation effect
[0040] 1. Extended service life: By separating cylinder 2 from the high-temperature environment, the operating temperature of cylinder 2 is significantly reduced, and its service life can be extended by 2-3 times.
