The tension adjustment component 7 also includes a connecting plate 704, a gravity block 706 and a fastening nut 707. One end of the connecting plate 704 is fixedly connected to the screw rod 703. The gravity roller 705 is movably installed at the position between the other ends of the connecting plate 704. The gravity block 706 is inserted on the screw rod 703 and is connected to the screw rod 703 through the fastening nut 707. The rod 703 is fixedly connected, and the slider 702 is in an I-shape. The two sides of the slider 702 are slidably connected to the side walls of the movable groove 701, so that the gravity roller 705 can be kept in a horizontal state. The overall gravity of the structure such as the gravity roller 705, the slider 702 and the gravity block 706 can be changed by changing different gravity blocks 706. The gravity can be adjusted reasonably, so that the gravity roller 705 can press the ribbon downward, but will not squeeze and deform the ribbon, so that the ribbon can be kept in a taut state under the squeezing of the gravity roller 705, so as to avoid the ribbon wrinkles affecting the hot printing of graphics and texts.

[0022] like Figure 1 , Figure 2 and Figure 4As shown, the limiting plate 708 is movably mounted on the No. 1 transmission roller 10 or the No. 2 transmission roller 11, the No. 2 cylinder 710 is fixedly connected to the connecting bracket 2, and the output shaft of the No. 2 cylinder 710 is fixedly connected to the limiting plate 708, the width detection sensor 712 is fixedly connected to the lower position of the connecting bracket 2, the PLC controller 713 is fixedly connected to the connecting bracket 2, the tensioning adjustment component 7 also includes a movable hole 709, the movable hole 709 is opened on the limiting plate 708, the limiting plate 708 is movably mounted on the No. 1 transmission roller 10 and the No. 2 transmission roller 11 through the movable hole 709, the tensioning adjustment component 7 also includes a mounting plate 711, the mounting plate 711 is fixedly connected to the connecting bracket 2, the width detection sensor 712 is fixedly connected to the mounting plate 711, the width detection sensor 712 detects the width of the ribbon and transmits the signal to the mounting plate 711.

The length of the No. 1 transmission roller 10 and the No. 2 transmission roller 11 is fixed. Subtract the detection width of the width detection sensor 712, and then subtract the reasonable reserved space length, and divide the remaining length by two to obtain the moving distance that the No. 2 cylinder 710 needs to execute. The PLC controller 713 controls the output shaft of the No. 2 cylinder 710 to move, so that the limiting plate 708 moves on the No. 1 transmission roller 10 and the No. 2 transmission roller 11 through the movable hole 709. The ribbon is located on both sides of the limiting plate 708. The limiting plate 708 prevents the ribbon from shifting to the side, so that the ribbon will not shift during the transmission process, thereby avoiding affecting the ribbon hot stamping.

[0023] It should be noted that the utility model is a fully automatic hot stamping machine, the ribbon roll is installed on the conveying roller 8, and then passes through the bottom surface of the gravity roller 705 at the side position, the top of the No. 1 transmission roller 10, the top of the No. 2 transmission roller 11, and the bottom surface of the gravity roller 705 on the other side, and finally is wound and stored in the receiving roller 9.

The gravity roller 705 moves downward under the action of gravity. The slider 702 on the side of the gravity roller 705 moves in the movable groove 701, so that the ribbon is squeezed downward and tightened to avoid ribbon wrinkles during hot stamping, which causes errors in hot stamping of graphics and texts. A screw 703 is fixedly connected to the slider 702. Different gravity blocks 706 can be connected to change the gravity of the overall structure of the gravity roller 705 and the slider 702, so as to facilitate the compression of the ribbon. A width detection sensor 712 is arranged between the gravity roller 705 and the No. 1 transmission roller 10, and the width detection sensor 712 is located below the ribbon to detect the width of the ribbon at the upper position, and then transmit the signal to the PLC controller 713. The PLC controller 713 calculates the moving distance of the No. 2 cylinder 710 pushing the limiting plate 708 according to the detected width, and controls the output shaft of the No. 2 cylinder 710 to move. The limiting plate 708 moves toward each other on the No. 1 transmission roller 10 and the No. 2 transmission roller 11, and the limiting plate 708 is used to limit the ribbon to the middle position of the No. 1 transmission roller 10 and the No. 2 transmission roller 11, so that the ribbon always remains centered to avoid displacement during the ribbon transmission process, which causes misalignment of the hot printing of the image and text.
