[0048] Working principle: When in use, the device is driven by a robot or other actuator (the robot (or other actuator) is connected to the frame 1 of the present application) to reach the position where the block material is placed. According to the size of the block material, the synchronous belt 5 is driven by the driving motor 4 to move and then the positions of the pull rods 9 on both sides are adjusted to clamp blocks of different sizes and place them on the material plate 2; when clamping the cloth, the front clamping cylinder 15 first drives the clamping claw 16 to clamp one end of the cloth. After the clamping is completed, the telescopic cylinder 14 contracts, and at the same time, the position of the pull rod 13 is adjusted by controlling the driving motor 26 to pull the cloth. After the cloth is pulled to the required length, the tail clamping cylinder 17 drives the clamping claw 2 18 to clamp the tail of the cloth, and then the rotating motor 19 and the servo cutter group 22 are started. While the servo cutter group 22 moves along the screw rod 20, the servo cutter group 22 will cut the cloth; after the cutting is completed, The pressing push rod 23 is started to lay the cloth through the pressing seat 24 (the outside air enters the piston cylinder 25 when the pressing seat is extended). At this time, the pneumatic push rod 36 drives the steering motor 37 to move according to the position of the pressing push rod 23, and then the steering motor 37 drives the fixing block 38 to rotate to fix the four corners of the cloth. After the fixation is completed, the pressing push rod drives the movable guide rail 2 30 to move downward and then drives the movable roller 34 to press the composite material downward. After the pressing is completed, the moving motor 31 is started to drive the moving block 32 to move along the movable guide rail 2 30 so as to move the movable roller 34. At the same time, the nozzle 35 will continue to spray horizontal airflow, and the wrinkles on the upper surface of the composite material are flattened through the cooperation of the two. Regarding the inflation of the air tank 27, when the infrared distance sensor 28 detects that the pressing push rod 23 is contracted, the pressing push rod 23 will drive the hollow piston rod 26 to move in the piston cylinder 25 and then fill the air into the air tank 27.
