▎ 摘　　要

NOVELTY - The machine has a driving wheel and a driven wheel rotatably mounted on a frame. A pressing assembly includes a fixing frame and a self-lubricating plate. A side of the self-lubricating plate is installed on the fixing frame. A pressing device is installed on one of the pressing assemblies. The pressing device includes a driving unit. A power output end is provided on the driving unit. The pressing device presses the self-lubricating plate to an inner side of a steel belt, so that the steel belt moves towards a transmission channel until the transmission channel narrows. The driving unit is an air pressure cylinder or a hydraulic cylinder. The plate is made of high-strength brass. The self-lubricating plate contains solid lubricant that is selected as graphite, graphene, molybdenum disulfide and hexagonal boron nitride. An accommodating groove is formed as a circle/strip/continuous track-shaped structure. USE - Double-steel belt pressing machine for use in composite material plate processing device. ADVANTAGE - The machine is simple in structure and inexpensive, and allows the pressing device for pressing the self-lubricating plate to an inner side of the steel belt, so that the steel belt moves towards a transmission channel until the transmission channel narrows to provide a stable surface pressure since there is a solid lubricant on the plate body of the self-lubricating plate, which makes solid lubricant to contact the steel belt on to prevent wear effect when the steel belt and the self-lubricating plate move relative to each other.
