[0029] The rotating module 3 includes two tensioning rollers 310, and the central axes at both ends of the two tensioning rollers 310 are movably connected to the two ends of the connecting plate 22 respectively. The end of the central axis of one end of the corresponding tensioning roller 310 is fixedly connected to the center of one side of the pulley 312, and the center of the other side of the pulley 312 is fixedly connected to the output shaft of the motor 38. The motor 38 is fixedly connected to the support plate 39, and the support plate 39 is fixedly connected to the connecting plate 22.

[0030] The end of the central axis of one end of the corresponding other tensioning roller 310 is fixedly connected to the center of a double-layer pulley 36, and the double-layer pulley 36 is connected to the pulley 1 312 through a belt 1 37. The central axis of the double-layer pulley 1 36 is movably connected to one end of a swing plate 1 32, and the double-layer pulley 1 36 is connected to a double-layer pulley 2 33 through a belt 2 35.

[0034] Working principle: When the device is in use, a set of bolts can be used to install the support frame 21 at a suitable position of the plastic bag production line, and then the raw film material is passed through the bottom of a corresponding tensioning roller 310, and then passed upward around the tensioning roller 311, and then passed downward from the bottom of another corresponding tensioning roller 310. At this time, the motor 38 is started, and the motor 38 drives the pulley 1 312 to rotate, and the pulley 1 312 drives the double-layer pulley 1 36 to rotate through the belt 1 37. The pulley 1 312 and the double-layer pulley 1 36 respectively drive the corresponding tensioning roller 310 to rotate, and the double-layer pulley 1 36 drives the double-layer pulley 2 33 to rotate through the belt 2 35, and the double-layer pulley 2 33 drives the pulley 2 313 to rotate through the belt 3 34.

According to the production rhythm, the raw film materials of different materials and thicknesses may be wrinkled during production. At this time, the electric push rod 11 is started, and the telescopic rod of the electric push rod 11 retracts to drive the slide plate 12 to move upward along the slide groove 13, so that the slide plate 12 drives the tensioning roller 311 to move upward, and the tensioning roller 311 drives the pulley 2 313, the swing plate 2 31, etc. to move. By adjusting the height of the tensioning roller 311, the length of the raw film material between the processes is increased or decreased, thereby eliminating the wrinkles of the raw film material on the production line, making the raw film material pulled and tightened, and better completing the production of the raw film material.

[0035] Beneficial effect: The raw film material is inserted from the bottom of a corresponding tensioning roller 310, then goes around the tensioning roller 311 upwards, and then goes out from the bottom of another corresponding tensioning roller 310 downwards. By rotating the module 3, the two tensioning rollers 310 and the tensioning roller 311 drive the raw film material to operate. According to the production rhythm, the wrinkles of raw film materials of different materials and thicknesses in production can be adjusted by adjusting the height of the tensioning roller 311 through the adjustment module 1, and the length of the raw film material between the processes can be increased or decreased, thereby eliminating the wrinkles of the raw film material on the production line, so that the raw film material is pulled and tightened, and the production of the raw film material is better completed.
