▎ 摘　　要

NOVELTY - The forming device has a base and a first plate structure (5). The upper side of the base is provided with a forming block and a feeding block. The upper side of the feeding block is provided with a feeding port. The upper side of the base is fixedly connected with a conveyor belt. The interior of the forming block is fixedly connected with a hydraulic cylinder. The output end of the hydraulic cylinder is fixedly connected with a positioning rod (34). The upper side of the first plate structure is fixedly connected with a connecting rod (9). One end of the second rod structure (17) is fixedly connected to the limiting block (18). One side of the second rod structure is fixedly connected with a second sliding block (16). One side of the second channel (11) is rotatably fitted with a cam (14). One side of the cam is provided with a sliding groove (15) compatible with the second sliding block. The upper side of the second channel is slidably fitted with a toothed plate (13). USE - Forming device for producing graphene polystyrene board. ADVANTAGE - The limiting relationship between the first plate structure and positioning rod is quickly canceled through the provided cam and linkage between the cam and the second rod structure, which is more convenient to replace the first board, thus the speed of replacing the first board is increased. The clamping rod quickly generates a limiting relationship with the positioning rod through the linkage between the first rotating shaft and second rotating shaft. The connection between the first board structure and positioning rod is made more firm, thus the stability of the first board structure is improved during work. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the base. 5First plate structure 9Connecting rod 10Groove 11Second channel 12Screw 13Toothed plate 14Cam 15Sliding groove 16Second sliding block 17Second rod structure 18Limiting block 19Worm 20First worm wheel 21First channel 22Rotating rod 34Positioning rod
