And two smoothing rollers 51 are arranged in the smoothing assembly 50 to clamp and smooth the ribbon 100, so that the ribbon 100 can be prevented from being wrinkled, and the gold stamping quality is further improved. The ribbon 100 can be preheated by the two flattening rollers 51 through the arrangement of the preheating part, the angles between the flattening rollers 51 and the cantilever 34 can be adjusted by the arrangement of the angle adjusting cylinder 541, and then the ribbon 100 in the gold stamping area can be inclined in the width direction to be matched with the upper surface of a workpiece, so that the adaptability of the gold stamping machine is improved.

For example, in order to facilitate the stamping operation, the traverse structure 48 includes a guide frame 481, a rotary cylinder 482 and a screw rod 483, the guide frame 481 is fixed on the output shaft of the stamping motor 41, the rotary cylinder 482 is mounted on one end of the guide frame 481, a slide block is protruded from the top of the receiving frame 451 and slidably inserted into the guide frame 481, and the screw rod 483 is connected to the output shaft of the rotary cylinder 482 and threadedly inserted into the slide block. A vertical beam 484 is convexly arranged at one end of the guide frame 481 far away from the rotary cylinder 482, one end of the screw rod 483 far away from the rotary cylinder 482 is rotatably arranged on the vertical beam 484, three mutually-spaced adjusting grooves 455 are concavely arranged in an opening of the accommodating frame 451, the number of the plurality of adjusting frames 452 is three, and the three adjusting frames 452 are respectively arranged in the three adjusting grooves 455.

Each adjusting bracket 452 comprises a cylindrical rod 4521, two connecting rods 4523 and two pivot shafts 4525, the cylindrical rod 4521 is disposed in the transverse groove 4551 of the adjusting groove 455, the two connecting rods 4523 are respectively vertically connected to two opposite ends of the cylindrical rod 4521 and are respectively disposed in the two longitudinal grooves 4553, the two pivot shafts 4525 are respectively vertically protruded at the bottom ends of the two connecting rods 4523, and two opposite ends of the bronzing roller 455 are respectively and rotatably connected to the two pivot shafts 4525. When hot stamping operation needs to be carried out, the screw rod 483 is driven to rotate through the rotating cylinder 482, so that the accommodating frame 451 can be driven to move back and forth, and the plurality of hot stamping rollers 455 support the ribbon 100 to roll back and forth on the surface of a workpiece, thereby realizing hot stamping operation. Because the gold stamping roller 455 is in line contact with the workpiece, the line contact has a larger holding force than the surface contact, and the gold stamping effect is better. And by rolling back and forth, the line contact can realize full coverage on the upper surface of the workpiece.

For example, it is particularly important that the hot stamping roller 455 is provided with a heat generating structure therein in order to facilitate the fitting of the inclined upper surface of the workpiece, and the hot stamping roller 455 is cylindrical. The middle of each connecting rod 4523 is provided with an elastic telescopic segment 4526. The length of the longitudinal groove 4553 is smaller than the width of the side wall plate 4513, that is, the bottom end of the longitudinal groove 4553 does not penetrate through the bottom of the side wall plate 4513, and the length of the connecting rod 4523 is 0.5 times of the length of the longitudinal groove 4553, that is, the connecting rod 4523 moves up and down in the longitudinal groove 4553, and the elastic telescopic segment 4526 can allow the gold stamping roller 455 to elastically contact with the upper surface of the workpiece to better fit the upper surface of the workpiece, and finally, the gold stamping roller is strongly supported after the force is increased. The longitudinal slot may guide the connecting rod and may also prevent the resilient telescopic segment 4526 from skewing for guidance. For example, in order to facilitate the initial state, i.e., to fit the upper surface of the workpiece, the upper surface of the receiving frame 451 is provided with three sets of screw holes, which correspond to the three adjusting grooves 455. Each set of screw holes includes two screw holes aligned with opposite ends of the transverse slot 4551 of the adjustment slot 455, each screw hole is screwed with a bolt 46, the bottom of the bolt 46 is provided with an arc-shaped pressing member 465, and the arc-shaped pressing member 465 presses and holds on the cylindrical rod 4521. The bolt 46 is used to adjust the uppermost position of the cylindrical rod 4521. During adjustment, the adjusting frame 452 descends under the driving of the gravity of the hot stamping roller, the bolt 46 rotates 180 degrees each time to form an adjusting unit, the bolt 46 can rotate for multiple circles to adjust the vertical height position of the bolt 46, and the arc-shaped pressing piece 465 can well press the cylindrical rod 4521 to adjust the highest position of the cylindrical rod 4521. The three gold stamping rollers 455 can be inclined to some extent by adjusting the height of the bolts 46 in each set of screw holes, and the three gold stamping rollers 455 can be inclined to the length direction of the ribbon 100 by adjusting the height of the bolts 46 in the three sets of screw holes. During hot stamping, the gravity of the hot stamping roller 455 and the elastic extension of the elastic telescopic section 4526 of the connecting rod 4523 enable the cylindrical rod 4521 to contact the arc-shaped pressing part 465, and after the contact, the elastic telescopic section 4526 is compressed, at the moment, the cylindrical rod 4521 and the arc-shaped pressing part 465 are in hard contact, and then the hot stamping roller can generate an inclination angle to be matched with the upper surface of the workpiece.

For example, in order to facilitate the winding of the ribbon 100, the ribbon assembly 30 further includes a winding frame 38 and two clamping rollers 39, the winding frame 38 includes a short rod 381 and a long rod 383 which are vertically connected to each other, an end of the short rod 381 is rotatably connected to the cross beam 22 and is adjacent to the second roller 32, a supporting rod 385 is convexly disposed at a connection portion of the short rod 381 and the long rod 383, the supporting rod 385 is supported on a side of the corresponding cantilever 34 away from the mounting frame 20, a tension spring is disposed on the cross beam 22, and one end of the tension spring is connected to the long rod 383 to force the long rod 383 to drive the supporting rod 385 to be supported on the cantilever 34. The long rod 383 extends towards the side away from the mounting frame 20, the two clamping rollers 39 are arranged in parallel with each other and are both rotatably mounted at the end of the long rod 383, and a clamping gap is formed between the two clamping rollers 39 for clamping the ink ribbon 100 for smoothing the ink ribbon 100 so that the ink ribbon 100 is smoothly wound on the second roller 32. Under different stamping conditions of workpieces, the leveling assembly 50 is located at a higher position and a lower position adjacent to the end of the cantilever 34 at the second roller 32, and in order to facilitate the second roller 32 to conveniently wind the ribbon 100, the winding frame 38 is configured to rotate under the support of the corresponding cantilever 34, so that the ribbon 100 is wound on the second roller 32 at a better angle. For example, when smoothing assembly 50 is lower, take-up reel 38 is closer to mounting rack 20, and when smoothing assembly 50 is higher, take-up reel 38 is farther from mounting rack 20 so that ribbon 100 is fed from smoothing assembly 50 onto second roll 32 in a less cornering orientation. While the two pinch rollers 39 smooth and tension the ribbon 100 to improve take-up quality.

It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
