Specifically, in the above technical solution, the carrier 56 is further provided with the second gear 53 and the third gear 54, and the second gear 53 and the third gear 54 are engaged with each other and symmetrically arranged with the first gear 52. Wherein: the second gear 53 and the third gear 54 are in mesh with each other and the sum of their diameters is equal to the length of the first gear 52. And the fourth gear 55 is mounted on the output end of the driving motor 21 and extends into the bracket 51 through the output end, and can be engaged with or disengaged from the second gear 53, the first gear 52 and the fifth gear 57 when the bracket 51 is moved (see fig. 4).

Further, in the above embodiment, when the abutting rod 31 moves to the end b, the cutting edge portion 312 (of the right triangle structure) at the bottom of the abutting rod 31 abuts against the end of the long shaft portion 322, so that the long shaft portion 322 is turned to a predetermined angle, the pulling of the tension spring 7 automatically reverses the direction of the swing link 32, and when the short shaft portion 321 stops at the stop 324, the long shaft portion 322 pushes the bracket 51 to move toward the feeding tray body 11, so that the fifth gear 57 is engaged with the orbital toothed disc 111, and the feeding tray body 11 is driven to rotate, where the rotation path is shown in fig. 10. At the same time, the first gear 52 will be out of gear with the sixth gear 72 on the shaft of the locking disc 12, and at the same time, the third gear 54 will drive the fourth gear 55 and the sixth gear 72 in mesh, and the rotation path is shown with reference to fig. 10.

When the loading tray 11 is rotatably installed in the port of the base 6, the wedge 61 is installed on the loading tray 11. When the fifth gear 57 drives the orbital fluted disc 111 to rotate, that is, after the feeding tray 11 rotates one circle, the wedge 61 is tangent to the short shaft portion 321 and pushed to rotate to a predetermined angle, the tension spring 7 is pulled down, the swing link 32 automatically reverses, until the long shaft portion 322 stops at the stop 324, the support 51 loses the pushing force and automatically resets, the fifth gear 57 is disengaged from the orbital fluted disc 111, and at the same time, the first gear 52 is engaged with the sixth gear 72 on the shaft of the locking disc 12 and is driven to rotate to discharge materials, and the rotation direction of the locking disc 12 is opposite to the position shown in fig. 10.

As a further embodiment of the present invention, the locking disc 12 is provided with a plurality of arc-shaped protrusions 121 arranged in a circumferential array, and the ends of the arc-shaped protrusions 121 extend out of the locking disc 12 and are tangent to the side walls of the tray groove portion 301. Specifically, the above technical feature is that the direction of inclination of the arc-shaped protrusion 121 coincides with the rotation direction of the first gear 52 for driving the lock disk 12. Therefore, when the loading tray body 11 is driven to rotate, the arc-shaped portion 302 picks the gold stamping roll into the guiding portion 300 from the tray, and then the gold stamping roll automatically slides into the tray groove portion 301 along with the switching process of the guiding portion 300 from the horizontal state to the vertical upward state.

Further, in the implementation of the above technical solution, the guide 300 is first horizontal to the bracket, then tilted and the bronzing roll is automatically slid along the guide 300 into the bracket 301. Because the rotation direction of the locking disc 12 is opposite to that of the feeding disc body 11, the arc top of the arc-shaped bulge 121 and the circular bulge are tangent in the rotation process to increase the friction damping of the downward sliding of the transmission shaft and reduce the downward sliding speed, and then the arc top moves along with the continuation of the arc-shaped bulge 121 to form the sweeping and pushing action, so that the transmission shaft is swept and pushed into the bracket part 301 to avoid directly sliding into the bracket part 301, the reciprocating swing of the whole gold stamping roll due to the self-weight relationship to form production is brought to the acting force between mechanical mechanisms, and the strength of the connecting parts of the parts is loosened.

As a further preferred embodiment of the present invention, the arc-shaped protrusion 121 is provided with a guide slot 122, and an end of the guide slot 122 extends into the locking plate 12. Specifically, as can be seen from fig. 7, the arc-shaped protrusions 121 in the above embodiment are wedge-shaped overall, and the width increases from one end of the locking plate 12 to the other end. In the embodiment, after the loading tray 11 completes loading, the locking tray 12 is driven to rotate by the first gear 52 (the rotation direction is opposite to the direction shown in fig. 10). It should be noted that, in the above embodiment, the unwinding mechanism 1 is symmetrically distributed, so when the transmission shaft is swept and pushed into the bracket portion 301, the circular protrusion is located at the arc bottom of the bracket portion 301, and then in the rotating process of the arc protrusion 121, the circular protrusion is shoveled into the guide slot 122, so as to lift the transmission shaft and keep the transmission shaft at the axis position of the bracket portion 301, when the circular protrusion reaches the bottom of the guide slot 122, the locking is completed, and the locking disc 12 drives the transmission shaft to synchronously rotate (when the transmission shaft is transmitted into the gold stamping roll, the transmission shaft needs to be fixed by the locking screw in advance) for unwinding.

Further, in the above technical solution, the circular protrusion at one end of the transmission shaft is of a T-shaped structure, and the cross sections of the guide grooves 122 in the unwinding mechanisms 1 at two sides are also of a T-shaped structure, so that when the circular protrusion is shoveled into the guide groove 122, the circular protrusion of the T-shaped structure at one side is adapted to the guide groove 122, and further, the entrance of the guide groove 122 is a guide lip 123 of an arc-shaped structure, so that when the maximum radius part of the T-shaped structure contacts the guide lip 123, the circular protrusion is shoveled into the guide groove 122, and is automatically slid to be matched (as shown in fig. 7). Thereby produce the effect that drags to realize putting the counterpoint work of golden line, avoid unreeling the problem that displacement about the in-process appears.

As a further technical solution provided by the present invention, the cross-sections of the teeth of the gears mentioned in the above embodiments are all as shown in fig. 6, which avoids the problem of tooth alignment caused in the butt joint process. The principle is simple and will not be explained too much.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
