Because many gold pieces device is equipped with a plurality of gold piece subassemblies that send, consequently gold piece slicing mechanism generally adopts two kinds of modes to cut into slices in prior art, one kind is longer with the cutter setting, and the gold piece that any one of them send gold piece subassembly to carry can all be cut by the cutter like this, realizes the section. And the other is that a plurality of gold sheet conveying assemblies integrally move on a moving frame, so that gold sheets conveyed by the corresponding gold sheet conveying assemblies needing to be sliced correspond to the position of the cutter, and slicing is realized. The long slicing knife is not neat enough in slicing, and a plurality of gold plate conveying assemblies are moved integrally in a mode of needing larger power and accurate guiding, so that the cost is higher.

Referring to fig. 6, the slicing mechanism 2 includes a cutter assembly and a driver, the cutter assembly includes a cutter base 21, a fixed cutter 22 connected to the cutter base 21, and a movable cutter 23 matched with the fixed cutter 22 to realize slicing, the driver includes a driving part for driving the movable cutter to move, and the slicing mechanism is matched with one of the gold sheet feeding assemblies to cut off gold sheets fed by the gold sheet feeding assembly.

Wherein, the driving component and the cutter seat 21 are driven by the color changing structure 3 to synchronously move transversely so as to correspond to the gold sheet feeding component matched with the change.

Because the cutter component integrally moves, the cutter component and the color changing driving part can synchronously move, so that the color of the sheet feeding mechanism 1 and the color of the slicing mechanism 2 can be changed simultaneously. In the present embodiment, the sheet feeding mechanism 1 and the sheet cutting mechanism 2 share an actuator, and the driving member is the driving cam 13 in the actuator. Specifically, the drive switching between the sheet feeding mechanism 1 and the sheet cutting mechanism 2 is realized by the forward and reverse rotation of the drive cam 13. For example, the driving cam 13 drives the gold blade feeding unit in the forward direction and drives the moving blade in the reverse direction, or vice versa. Therefore, the driving cam 13 is used as the driving member, which is advantageous in that the driving switching of the sheet feeding mechanism 1 and the sheet cutting mechanism 2 can be realized by the forward and reverse rotation of the driving cam 13, and the driver realizes two driving functions with the simplest structure.
