Thermal compounding machine for acoustic material in air environment

Abstract

The invention relates to a thermal compounding machine for an acoustic material in air environment. The thermal compounding machine comprises a bracket, a pressurizing mechanism and a heating unit, wherein the bracket is of a cuboid structure; the heating unit is supported by a U-shaped sealing plate and is installed at the top of the bracket; a bottom sealing plate is arranged at the bottom of the heating unit; the two ends of the heating unit are each provided with a perforated side sealing plate; H-shaped struts are correspondingly and separately installed at the two ends of the bracket; two U-shaped crossbeams are oppositely installed at the tops of the H-shaped struts; each hydraulic cylinder is installed at the corresponding U-shaped crossbeam; the pressurizing mechanism comprises a pressing plate and a pressing plate fixing frame; the pressing plate fixing frame is connected with an output shaft of a hydraulic cylinder; the pressing plate is installed at the bottom of the pressing plate fixing frame and corresponds to the heating unit in position in the vertical direction; and the pressurizing mechanism realizes thermal pressing by virtue of driving of the hydraulic cylinder. The thermal compounding machine provided by the invention can precisely control the pressure value and the thermal pressing time, is used for realizing thermal-pressing compounding of the acoustic material in the air environment and can meet the pneumatic and acoustic requirements of the air environment in application.

Description

technical field [0001] The invention belongs to the technical field of thermocompression compounding, and in particular relates to a thermal compounding machine for airflow environment acoustic materials. Background technique [0002] When processing some materials that are composited by two materials, the usual methods include welding, bonding, etc. When processing acoustic materials, due to various restrictions, such as certain sound-absorbing materials that cannot be welded, environmental protection and fire prevention Request etc. cannot be used. [0003] When acoustic materials are applied under airflow conditions, there are aerodynamic and acoustic requirements in the processing process, such as wind tunnel structures. Therefore, general hot presses cannot be used for thermal compression lamination of acoustic materials. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a thermal lamination machine for acous...
