DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a multifunctional dual-axis slitting machine for paper printing. Figure 1-3 A multifunctional double-axis slitting machine for paper printing comprises a workbench 1, the top outer wall of the workbench 1 is fixedly connected with two fixed plates 2, the outer walls opposite to the two fixed plates 2 are fixedly connected with a plurality of guide rails 3, the outer walls of the plurality of guide rails 3 are slidably connected with sliders 4, the outer walls of the plurality of sliders 4 are fixedly connected with a mounting plate 5, the bottom outer wall of the mounting plate 5 is detachably mounted with a cutting knife 6, the bottom outer wall of the mounting plate 5 is fixedly connected with a plurality of telescopic rods 9, the cutting knife 6 is located between two adjacent telescopic rods 9, the bottom ends of every two telescopic rods 9 at a longer distance are fixedly connected with a mounting frame 11, the outer wall of the mounting frame 11 is rotatably connected with a pressing roller 12, the outer walls of the plurality of telescopic rods 9 are installed with springs 10, and the outer walls of the two fixed plates 2 are installed with a reciprocating component for driving the cutting knife 6 to cut.

[0020] An arch block 7 is fixedly connected to the top outer wall of the workbench 1 . A cutting groove 8 is provided on the middle top outer wall of the arch block 7 . The cutting groove 8 is located directly below the cutting knife 6 . Two pressing rollers 12 are located directly above the arch block 7 .

[0021] The reciprocating assembly includes a fixing frame 13 fixedly connected to the opposite outer walls of the two fixing plates 2, the bottom ends of the two fixing frames 13 are fixedly connected to drive motors 14, and the output shaft ends of the two drive motors 14 pass through the fixing plates 2 and are fixedly connected to eccentric wheels 15.

[0022] The reciprocating assembly further comprises a central shaft 16 fixedly connected to the outer wall between the two eccentric wheels 15 , and a connecting rod 17 is rotatably connected to the outer wall of the central shaft 16 .

[0023] Two hinges 18 are fixedly connected to the top outer wall of the mounting plate 5 , and one end of the connecting rod 17 away from the central axis 16 is hinged inside the hinge 18 .

[0024] The implementation principle of a multifunctional double-axis slitting machine for paper printing in the embodiment of the present application is as follows: when in use, the paper product is passed between the cutting knife 6 and the arch block 7, and the paper is laid on the surface of the arch block 7 to be cut. When cutting, the two driving motors 14 are started through the reciprocating component, and the output shafts of the two driving motors 14 rotate to drive the eccentric wheel 15 to rotate. The eccentric wheel 15 drives the central axis 16 to rotate around the output shaft of the driving motor 14 as the axis, thereby pushing or pulling the connecting rod 17 to move up and down. The connecting rod 17 pushes or pulls the mounting plate 5 to move up and down through the hinge 18. The mounting plate 5 drives multiple sliders 4 to slide on the outer wall of the guide rail 3, which plays a guiding and limiting role, so that the mounting plate 5 can only move up and down. When the mounting plate 5 moves, the cutting knife 6 is driven to press down to cut the paper when the mounting plate 5 descends. Before the cutting knife 6 contacts the paper, the two pressing rollers 12 will first contact the paper. Then, when the mounting plate 5 continues to descend, the pressing roller 12 presses the telescopic rod 9 upward. The telescopic rod 9 shortens and squeezes the spring 10 through the mounting frame 11. The spring 10 deforms and generates elastic force to act in the opposite direction on the mounting frame 11. The mounting frame 11 drives the pressing roller 12 and the arch block 7 to press the paper and tension the paper. At this time, the paper is tensioned and fixed. As the cutting knife 6 descends and extends into the cutting groove 8, the paper can be cut. In this way, the paper can be tensioned and fixed in advance before cutting, so that the cut of the paper is smooth and flat after cutting, thereby improving the quality of cutting.
