Detailed implementation manner

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] Refer to Figure 1-7 , the precise adjustment device of the flat-bed die-cutting machine, including a base 1. A moving groove is provided on the outer wall of the base 1, and two sliding grooves are provided on the upper end surface of the base 1. Two sliders 3 are slidably installed in each of the two sliding grooves through a sliding mechanism. The sliding mechanism includes a slide bar 2 fixedly installed in the sliding groove. The slide bar 2 slidably penetrates through the two sliders 3. The bottom walls of the two opposite sliders 3 are jointly fixedly installed with a connecting block 4. The bottom walls of the two connecting blocks 4 are both fixedly installed with a first connecting frame 5. A rotating plate 6 is rotatably installed on the inner wall of the moving groove. The bottom wall of the rotating plate 6 is fixedly installed with a second connecting frame 7. The interiors of the two second connecting frames 7 are rotatably connected to the interior of the first connecting frame 5 on the same side through a connecting mechanism. The connecting mechanism includes a connecting plate 8 rotatably installed in the second connecting frame 7. The end of the connecting plate 8 is rotatably connected to the interior of the first connecting frame 5.

[0028] An electric push rod 10 is fixedly installed on the inner bottom wall of the moving groove through a support mechanism. The support mechanism includes a support plate 9 fixedly installed on the inner bottom wall of the moving groove. The electric push rod 10 is fixedly installed on the outer wall of the support plate 9. The telescopic end of the electric push rod 10 is fixedly connected to the bottom wall of one of the connecting blocks 4 through a fixing mechanism. The fixing mechanism includes a fixing plate 11 fixedly installed on the telescopic end of the electric push rod 10. The end of the fixing plate 11 is fixedly connected to the bottom wall of the connecting block 4. The upper end surface of each slider 3 is fixedly connected to a connecting plate 13 through a connecting mechanism. The connecting mechanism includes a connecting rod 12 fixedly installed on the upper end surface of the slider 3. The end of the connecting rod 12 is fixedly connected to the outer wall of the connecting plate 13. The inner walls of the two opposite connecting plates 13 are jointly fixedly connected with a positioning plate 15 through an elastic mechanism. The elastic mechanism includes a spring telescopic rod 14 fixedly installed on the inner wall of the connecting plate 13. The telescopic end of the spring telescopic rod 14 is fixedly connected to the outer wall of the positioning plate 15.

[0029] On the upper end surface of the base 1, a support frame 16 is fixedly installed. The bottom wall of the support frame 16 is fixedly connected to a moving frame 18 through a lifting mechanism. The lifting mechanism includes a cylinder 17 fixedly installed on the bottom wall of the support frame 16. The telescopic end of the cylinder 17 is fixedly connected to the upper end surface of the moving frame 18. Two stabilizing rods 19 are slidably installed through the upper end surface of the support frame 16. Both ends of the two stabilizing rods 19 are fixedly connected to the upper end surface of the moving frame 18. A double-headed screw rod 20 is rotatably installed inside the moving frame 18. A motor 21 connected to the double-headed screw rod 20 is fixedly installed on the outer wall of the moving frame 18. Two moving plates 23 are threadedly installed on the double-headed screw rod 20. A limiting rod 22 is fixedly installed inside the moving frame 18. The limiting rod 22 slidably penetrates through the two moving plates 23. The limiting rod 22 can restrict the two moving plates 23, so that the two moving plates 23 can only axially move along the outer wall of the double-headed screw rod 20. Cutting tools 24 are fixedly installed on the bottom walls of both moving plates 23.

[0030] When the present utility model is in use, place the printed matter on the upper end surface of the base 1. At this time, when the electric push rod 10 contracts, it can drive one of the connecting blocks 4 to move through the cooperation of the fixing plate 11 (the initial state of the electric push rod 10 is fully extended). One of the connecting blocks 4 can drive the rotating plate 6 to rotate through the cooperation of two groups of first connecting frames 5, second connecting frames 7 and the connecting plate 8. At this time, both connecting plates 8 are in a parallel inclined state. Through the pulling of the two connecting plates 8, the two connecting blocks 4 can respectively drive the two opposite sliders 3 to slide on the outer wall of the sliding rod 2. Thus, the two positioning plates 15 can be moved closer to each other to clamp and position the printed matter. And when the electric push rod 10 contracts, it can adjust the inclination degree of the two connecting plates 8, so as to conveniently adjust the distance between the two positioning plates 15, so as to position printed matters of different widths.

[0031] After the printed matter is placed, the cylinder 17 can drive the moving frame 18 to descend. The moving frame 18 then drives the two cutting tools 24 to perform die-cutting and indentation processing on the printed matter. When the moving frame 18 descends, it can also drive the two stabilizing rods 19 to slide on the bottom wall of the support frame 16. Thus, the stability of the moving frame 18 during movement can be increased. And during the die-cutting and indentation processing, the printed matter deforms under force. At this time, through the elastic cooperation of multiple spring telescopic rods 14, the positions of the two positioning plates 15 can be adjusted according to the deformation of the printed matter while maintaining the positioning of the printed matter, avoiding excessive clamping and positioning from affecting the die-cutting and indentation processing of the printed matter. When it is necessary to adjust the distance between the two cutting tools 24, the motor 21 can drive the double-headed screw rod 20 to rotate. When the double-headed screw rod 20 rotates, it can drive the two moving plates 23 to move through the cooperation with the limiting rod 22. Thus, the two moving plates 23 can respectively drive the cutting tools 24 at their bottom walls to move, so that the two cutting tools 24 can be conveniently adjusted according to different requirements for die-cutting and indentation processing.

[0032] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
