[0031] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.
[0032] Please refer to Figure 1, A die-cutting device in this embodiment includes a bottom plate 1, a feeding device 2 arranged on the top surface of the bottom plate 1, a die-cutting table 3 fixed on the top surface of the bottom plate 1, four guide rods 4 fixed on the top surface of the die-cutting table 3, a top plate 5 fixed at the top ends of the four guide rods 4, a press 6 fixed on the top surface of the top plate 5, a pressure plate 7 fixed at the bottom end of the output shaft of the press 6, a die-cutting knife 8 installed on the bottom surface of the pressure plate 7, a blanking mechanism arranged on the pressure plate 7, and an installation mechanism arranged on the pressure plate 7. When in use, the die-cutting knife 8 is installed at the bottom of the pressure plate 7 through the installation mechanism, realizing the quick loading and unloading of the die-cutting knife 8, thereby facilitating the disassembly, maintenance, and replacement of the die-cutting knife 8. Then, the cardboard for making the packaging box is placed on the feeding device and conveyed to the die-cutting table 3. Then, the press 6 is controlled to push the die-cutting knife 8 downward for die-cutting. A blanking mechanism is arranged inside the die-cutting knife 8. After the die-cutting knife 8 completes die-cutting, it will automatically push down the cardboard cut by the die-cutting knife 8, preventing the cardboard from getting stuck inside the die-cutting knife 8 and affecting die-cutting. It has better practicability and is more convenient for popularization and use.
[0033] It should be noted that the feeding device 2 is a conveyor belt feeding structure, which is a mature and publicly disclosed device in the prior art. For example, the above-mentioned retrieved patent discloses this technology. Therefore, the specific structure and working principle of the feeding device 2 will not be elaborated in detail in this application. In addition, the control method of this application is controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common knowledge in this field. And this application is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail in this application.
[0034] Four guide holes for the vertical penetration and sliding connection of the guide rods 4 are opened on the top surface of the pressure plate 7. The guide rods 4 are used for the pressure plate 7 to slide up and down between the top plate 5 and the die-cutting table 3. The die-cutting table 3 and the die-cutting knife 8 are vertically opposite to each other, and the die-cutting knife 8 is an annular tool.
[0035] Please refer to Figures 1-3, the blanking mechanism includes a sliding rod 901 fixed to the bottom surface of the pressure plate 7, a sliding block 902 slidably connected to the outer peripheral wall of the sliding rod 901, a blanking spring 903 sleeved on the outer peripheral wall of the sliding rod 901, two connecting rods 904 threadedly connected to the outer peripheral wall of the sliding block 902, a pushing rod 905 fixed to one end of the connecting rod 904 away from the sliding block 902, and a limiting plate 906 fixed to the bottom end of the sliding rod 901. During use, the feeding mechanism conveys the cardboard to the top of the die-cutting table 3, and then the press 6 controls the pressure plate 7 to move downward along the guide rod 4. The pressure plate 7 drives the die-cutting knife 8 to move downward to contact the cardboard and apply a certain pressure to it, so that the die-cutting knife 8 cuts the cardboard. When the bottom surface of the die-cutting knife 8 contacts the top surface of the cardboard, at this time the pressure plate 7 continues to move downward for cutting. Since the die-cutting knife 8 does not completely cut through the cardboard and the cardboard is a whole, it will cause the cardboard to contact the bottom end of the pushing rod 905. At this time, the pushing rod 905 will drive the sliding block 902 to slide upward along the sliding rod 901 and cannot compress the blanking spring 903. When the die-cutting knife 8 cuts through the cardboard, at this time the cardboard inside the die-cutting knife 8 is cut off. Further, whether the elastic force of the blanking spring 903 drives the sliding block 902 to move downward, and then the pushing rod 905 moves downward to push the cardboard out downward from the inside of the die-cutting knife 8 for blanking, avoiding the inconvenience caused by the cardboard getting stuck inside the die-cutting knife 8.
[0036] In this embodiment, a sliding hole for the sliding rod 901 to vertically penetrate and slidably connect with it is provided on the top surface of the sliding block 902. The blanking spring 903 is arranged on the top of the sliding block 902. The bottom end of the pushing rod 905 is flush with the bottom surface of the die-cutting knife 8. Threaded holes for the connecting rods 904 to be threadedly connected are provided on both the left and right sides of the sliding block 902, and the two threaded holes are distributed front and back. Threaded grooves adapted to the threaded holes are provided on the outer peripheral wall of the connecting rod 904. When replacing the die-cutting knife 8 with different-sized tools, by rotating the connecting rod 904, it can drive the pushing rod 905 to move left and right through the provided threaded holes and threaded grooves, so as to facilitate adapting to different-sized die-cutting knives 8.
[0037] Please refer to Figure 2 and Figure 4In this embodiment, the mounting mechanism includes a mounting ring 1001 fixed on the outer peripheral wall of the die cutting knife 8, four mounting plates 1002 fixed on the top surface of the mounting ring 1001, two support plates 1003 fixed on the top surface of the pressure plate 7, a limit rod 1004 horizontally penetrating the support plate 1003 and slidably connected thereto, an extrusion plate 1005 fixed on the outer peripheral wall of the limit rod 1004, a limit spring 1006 sleeved on the outer peripheral wall of the limit rod 1004, and four sub- The connecting block 1007 is fixed on the opposite side of the two limiting rods 1004, the limiting block 1008 is fixed on the left side of the connecting block 1007, and the operating rod 1009 is fixed on the right end of the two limiting rods 1004. The right side of the mounting plate 1002 is provided with a limiting hole 1010 for the limiting block 1008 to pass through. When the die cutting knife 8 needs to be installed and removed for maintenance, the operating rod 1009 is pulled to the right, and the operating rod 1009 drives the two limiting rods 1004 to move to the right. The rod 1004 drives the four connecting blocks 1007 to move rightward synchronously, thereby causing the four limiting blocks 1008 to move rightward synchronously and disengage from the limiting holes 1010 on the mounting plate 1002. At this time, the die cutter 8 can be moved downward to drive the mounting plate 1002 to move downward for disassembly. The two connecting blocks 1007 on the same limiting rod 1004 are distributed on the left and right, and the four connecting blocks 1007 are respectively opposite to the four mounting plates 1002 on the left and right. The extrusion plate 1005 is located on the support plate 1 On the left side of 003, a limit spring 1006 is arranged between the extrusion plate 1005 and the support plate 1003. When the limit rod 1004 moves to the right, it will drive the extrusion plate 1005 to cooperate with the support plate 1003 to compress the limit spring 1006. When installing the die-cutting knife 8, the above operation will be reversed. The limit spring 1006 will push the limit rod 1004 to reset and drive the limit block 1008 to be inserted into the limit hole 1010 to limit and fix the installation plate 1002.
[0038] In this embodiment, the top surface of the pressure plate 7 is provided with four mounting holes for the mounting plate 1002 to pass through and to fit with the mounting plate 1002 in a clearance, the two support plates 1003 are opposite to each other front and back, and the right side of the support plate 1003 is provided with a through hole for the limiting rod 1004 to pass through and to be slidably connected with the limiting rod 1004.
[0039] The working principle of the above embodiment is:
[0040] (1) When in use, the feeding mechanism conveys the cardboard to the top of the die-cutting table 3, and then the press machine 6 controls the pressure plate 7 to move down along the guide rod 4, and the pressure plate 7 drives the die-cutting knife 8 to move down and contact the cardboard and exert a certain pressure on it, so that the die-cutting knife 8 cuts the cardboard. When the bottom surface of the die-cutting knife 8 contacts the top surface of the cardboard, the pressure plate 7 continues to move down for cutting. Since the die-cutting knife 8 has not completely cut through the cardboard, the cardboard is a whole, which will make the cardboard contact with the bottom end of the push rod 905. At this time, the push rod 905 will drive the sliding block 902 to slide up along the sliding rod 901 through the connecting rod 904, and the unloading spring 903 cannot be compressed. When the die-cutting knife 8 cuts through the cardboard, the cardboard inside the die-cutting knife 8 is cut off. The sliding block 902 is further driven downward by the elastic force of the unloading spring 903, and then the push rod 905 moves down to push the cardboard downward from the inside of the die-cutting knife 8 for unloading, thereby avoiding the cardboard being stuck inside the die-cutting knife 8 and causing inconvenience;
[0041] (2) When the die-cutting knife 8 needs to be loaded and unloaded for maintenance, the operating rod 1009 is pulled to the right. The operating rod 1009 drives the two limit rods 1004 to move to the right. The two limit rods 1004 drive the four connecting blocks 1007 to move to the right synchronously, thereby causing the four limit blocks 1008 to move to the right synchronously and disengage from the limit holes 1010 on the mounting plate 1002. At this time, the die-cutting knife 8 can be moved downward, causing it to drive the mounting plate 1002 to move downward for disassembly. When the limit rod 1004 moves to the right, it drives the extrusion plate 1005 to cooperate with the support plate 1003 to compress the limit spring 1006. When installing the die-cutting knife 8, the above operation is reversed. The limit spring 1006 pushes the limit rod 1004 to reset and drives the limit block 1008 to be inserted into the limit hole 1010 to limit and fix the mounting plate 1002.
