the specific structure of the utility model is shown in fig. 1-5, and the main structure comprises a restraining component for restraining the carving sheets a to be in a stacked arrangement and a pushing component for pushing the carving sheets a in the restraining component to generate a lifting action. Wherein:

the constraint component comprises a guide groove 10 with an outward notch fixed on the frame 80, a material box 20 with an inward notch is detachably arranged in a groove cavity of the guide groove 10, and a corresponding engraving sheet a is arranged in the groove cavity of the material box 20 as shown in figure 3. The profile of the guide channel 10 and the magazine 20 is shown with reference to fig. 2-5, i.e. the channel length is the same and the notches are opposite. In order to ensure the fixing effect of the material box 20 relative to the guide groove 10, the outer wall of the material box 20 is provided with a convex matching plate 23, the cavity of the guide groove 10 is provided with a convex spigot plate 12, and when the material box 20 is clamped into the guide groove 10, the spigot of the spigot plate 12 from top to bottom is matched with the matching plate 23, so that the material box 20 is limited to generate continuous downward movement in the axial direction. Meanwhile, the notch of the guide groove 10 is hinged with a pressing plate 51 as shown in fig. 2, and the clamping state as shown in fig. 1 is realized through the matching of the pressing plate 51 and the bayonet 52, so that the material box 20 is limited to be radially separated from the guide groove 10 from the notch of the guide groove 10. The back of the trough of the magazine 20 can be provided with a handle to improve the convenience of assembly and disassembly.

Due to the detachability of the magazine 20 and the guide groove 10, the magazine 20 is designed to be replaceable, a plurality of magazines 20 filled with carving sheets can be prepared for standby at the same time, and the carving sheets in the magazine 20 in the guide groove 10 can be replaced quickly after being used up. Meanwhile, the material box 20 can be used as long as the shape is consistent, even the shape is different, the matching plate 23 can be designed to be matched with the groove cavity of the guide groove 10, and the compatibility is strong.

In actual installation, the engraved plates a are stacked in the magazine 20 as shown in fig. 3, so that the magazine 20 assumes a magazine-like assembled state. The bottom slot end of the magazine 20 is provided with a constriction 21 to ensure that the engraving sheet a does not fall out of the magazine 20 there. The notch of the magazine 20 is provided with an inner flange 22, forming a neck trough shape. The closing-in 21 at the bottom of the magazine 20 can be passed through by the supporting plate 31 at the thrust member, and the clearance reserved between the inner flanges 22 also forms an escape passage for the action of the jacking arm 30 of the thrust assembly.

As shown in fig. 3 to 5, the thrust member includes a screw slider mechanism provided with a power motor; the screw slide block mechanism comprises a power screw 41 and a power slide block 43 which are arranged on a power seat 42. The power slide block 43 is fixedly connected with the horizontal section of the jacking arm 30, and the vertical section of the jacking arm 30 is fixedly connected with the supporting plate 31. In operation, as shown in fig. 3-5, the jacking arm 30 horizontally passes through the through hole 11 of the guide slot 10, and then vertically extends into the material box 20 from bottom to top, so as to realize the functions of supporting the carving sheet a in the material box 20 from bottom to top and automatically feeding the carving sheet a through the supporting plate 31.

In addition to the above-described structure, it is also conceivable to arrange the detection sensor 60 on the constraining member so as to monitor the position of the uppermost engraved sheet. The switching button 70 is used for directly pressing the switching button 70 to reset the jacking arm 30 when the carving sheets in the first material box set are used, at the moment, the jacking arm 30 retreats from the empty material box, and then the operation of detaching the empty material box and loading a new material box can be executed. Even if necessary, the supporting plate 31 at the position of the jacking arm 30 can be extended into the material box 20 from bottom to top again by pressing the switching button 70 until the carving sheet at the uppermost layer rises to the position of the detection sensor 60, so that the working efficiency and the stability of the subsequent assembly are ensured.

To facilitate a further understanding of the utility model, specific work flows of the utility model are set forth herein as follows:

1) when the switching button 70 is pressed down, the power motor starts to work, and the screw rod sliding block mechanism is driven to drive the jacking arm 30 to descend to the lower limit position; then, the pressing plate 51 is opened, the empty magazine 20 is taken out, and the full magazine 20 is placed;

2) closing the upper pressure plate 51, pressing the switching button 70, driving the jacking arm 30 to ascend by the screw rod slider mechanism, synchronously driving the carving sheets in the full material box 20 to ascend along the groove cavity of the material box 20, and stopping the action of the jacking arm 30 until the carving sheet on the uppermost layer is detected by the detection sensor 60;

3) when the device works, the state that the detection sensor 60 detects the current uppermost layer carving sheet is always kept; after the carving mechanical arm takes out the carving sheet on the uppermost layer, the power motor drives the screw rod sliding block mechanism to act once, the second layer of carving sheets is jacked to be detected by the detection sensor 60 again, and then the power motor stops acting. At the moment, the original second layer of carving sheets becomes the current uppermost layer of carving sheets, so that the carving sheets are kept at the uniform height to be taken all the time.
