[0042] Referring to Figures 1-5 The utility model provides a die -cutting machine for decorative film production, including main part assembly 1, main part assembly 1 includes: support 11, the top symmetrical arrangement is provided with apron 12, be provided with replacement assembly 2 on apron 12, replacement assembly 2 includes: pivot 21, rotationally connected in the facing surface of apron 12, top plate 22 is fixedly connected in the outer side wall of pivot 21, support 231 is fixedly connected in the inner side wall of apron 12, electric push rod 23 is set up in the top of support 231, rack 24 is slidably connected in the top of support 231, one end of rack 24 is fixedly connected with the output shaft of electric push rod 23, gear 25 is fixedly connected in the outside of pivot 21 and is engaged with rack 24, top plate 22 is provided with die -cutting mechanism 13 in the bottom, die -cutting mechanism 13 is provided with frame 26 in the bottom, cutting knife 14 is provided with in the bottom of frame 26, and fixed mechanism 27 is set up between frame 26 and cutting knife 14. Fixed mechanism 27 includes: cavity 271 is set up in the inside of frame 26, spring 272 is fixedly connected in one end in the inside wall of cavity 271, optical axis 273 is inserted in the inside wall of cavity 271, crossbar 274 is fixedly connected in the other end of spring 272, crossbar 274 is inserted and slidably connected in the optical axis 273, push rod 275 is fixedly connected in the side away from spring 272 of crossbar 274, and the other end of push rod 275 is inserted and extends to the outside of frame 26, push plate 276 is fixedly connected in the one end of push rod 275 located in the outside of frame 26, and limiting rod 277 is fixedly connected in the top of cutting knife 14. Fixed mechanism 27 is provided with multiple groups symmetrically, and is provided with at least two groups.

[0043] In use, the staff uses die -cutting mechanism 13 to carry out die -cutting to decorative film, when needing to replace decorative film cutting shape, staff uses replacement assembly 2 to replace cutting knife 14: staff controls the elongation of electric push rod 23, and the rack 24 is moved when the elongation of electric push rod 23, the top engagement gear 25 drives pivot 21 counterclockwise rotation (with the pivot 21 of decorative film cutting shape as the rotation center) when the rack 24 moves, and the staff can replace cutting knife 14 in the top of pivot 21. Figure 2When the cutting knife 14 needs to be disassembled, the worker pushes the push plate 276 towards the frame 26, the push plate 276 drives the push rod 275 and the horizontal rod 274 to move, the horizontal rod 274 moves towards the spring 272, gets out of the groove of the limiting rod 277, and compresses the spring 272, at this time the worker can take off the cutting knife 14 together with the limiting rod 277 from the frame 26, then inserts the limiting rod 277 on the cutting knife 14 of different style into the cavity 271, releases the push plate 276, the spring 272 rebounds to make the horizontal rod 274 pop into the groove of the limiting rod 277, and the horizontal rod 274 limits the limiting rod 277 and the cutting knife 14, so as to complete the replacement of the cutting knife 14. The horizontal rod 274 slides on the optical axis 273 when moving, the optical axis 273 guides the movement of the horizontal rod 274, increases the stability when the horizontal rod 274 moves, and facilitates the fixation of the limiting rod 277. After the replacement of the cutting knife 14 is completed, the worker controls the electric push rod 23 to retract, the rack 24 drives the gear 25 to reverse when moving, the top plate 22 drives the die-cutting mechanism 13 and the cutting knife 14 to flip back to the original position, facilitating subsequent die cutting. The fixing mechanism 27 is used for installing and fixing the cutting knife 14, a plurality of fixing mechanisms 27 are arranged, the fixing effect of the device on the cutting knife 14 is increased, the stability after the cutting knife 14 is fixed is increased, and the accuracy of subsequent die cutting of the cutting knife 14 is facilitated.

[0044] Embodiment two

[0045] On the basis of embodiment one, an auxiliary function is added.

[0046] Reference Figures 1-5 The limiting rod 277 has an inclined surface. The distance between the grooves of the limiting rod 277 is equal to the diameter of the horizontal rod 274. The bottom of the rack 24 is fixedly connected with a sliding block 241, and the top of the support 231 is provided with a sliding groove 242, and the sliding block 241 is slidingly connected in the sliding groove 242.

[0047] The slope on the limiting rod 277 enables the staff to fix the limiting rod 277 without pressing the push plate 276 in advance: the staff directly inserts the limiting rod 277 into the cavity 271, the slope on the limiting rod 277 pushes the cross rod 274 to the spring 272 direction when passing through the cross rod 274, thereby avoiding affecting the limiting rod 277 from entering the limiting rod 277, at this time the spring 272 is extruded, when the limiting rod 277 is completely inserted into the cavity 271, the groove on the limiting rod 277 is located at the same horizontal line with the cross rod 274, at this time the spring 272 with elasticity pushes the cross rod 274 into the groove on the limiting rod 277, thereby realizing the automatic fixing of the limiting rod 277, and increasing the convenience of operation. When the rack 24 moves on the support 231, the bottom sliding block 241 slides in the sliding groove 242, the sliding block 241 and the sliding groove 242 are used for increasing the stability when the rack 24 moves, thereby facilitating the timely linkage of the top engaged gear 25. Since the groove on the limiting rod 277 is equal in diameter with the cross rod 274, after the cross rod 274 enters the groove on the limiting rod 277, it cannot move in the groove, thereby avoiding affecting the stability after the limiting rod 277 is connected.

[0048] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
