[0024] Embodiment 2

[0025] like Figure 1-5 As shown, the utility model proposes a paper folding creasing machine, compared with the first embodiment, this embodiment also includes: two groups of creasing components are symmetrically arranged on the lower pressing plate 3, which can make one more mark at a time, thereby improving work efficiency. The shape of the protrusion 16 is T-shaped, which is convenient for limiting the electric telescopic rod 9. The mounting frame 2 is provided with a second slide groove 202 at the center of the two slide grooves 1 201 on the same side, and the electric telescopic rods 9 sliding on the slide groove 1 201 are connected to the telescopic connecting rod structure 17 by rotation; the telescopic connecting rod structure 17 is composed of a plurality of rhombus rotating frames to achieve horizontal telescopic extension, and the two ends are connected to the electric telescopic rod 9 on the same side, and a connecting shaft is rotatably arranged in the middle; the connecting shaft is slidably connected to the second slide groove 202, which can limit the electric telescopic rod 9 and prevent the electric telescopic rod 9 from slipping.

The cylinder body of the hydraulic cylinder 4 is connected to the mounting frame 2, and the telescopic rod part passes through the mounting frame 2 and is connected to the lower pressing plate 3.

[0026] The working principle of the utility model is as follows: when working, first place the paper on the upper surface of the machine body 1, and then adjust the number of the creasing knife units 7 according to the required creasing length. First, start the electric telescopic rod 9, so that the electric telescopic rod 9 extends into the adjustment gap of the creasing knife unit 7 that does not need to be activated, and then move one side of the electric telescopic rod 9 in the direction of the second slide slot 202, so that the telescopic connecting rod structure 17 is compressed, and the electric telescopic rods 9 on both sides move synchronously towards each other. The movement of the electric telescopic rod 9 simultaneously drives the convex block 16 to move, thereby causing the telescopic block 14 to disengage from the second limiting hole 11 and slide into the fixing frame 13 to compress the spring 15. Then, the electric telescopic rod 9 on one side is pushed upward, thereby driving the second tool holder 702 to slide upward along the tool holder 1 701. When the electric telescopic rod 9 moves to the top of the slide slot 1 201, the through hole 12 is just opposite to the limit hole 10. At this time, the electric telescopic rod 9 is released, and the spring 15 is restored to push the telescopic block 14 into the limit hole 10, so that the telescopic block 14 and the limit hole 10 are mutually engaged. The upward movement of the electric telescopic rod 9 also drives the connecting shaft to slide upward in the slide slot 202. At the same time, the spring 15 is reset to push the electric telescopic rod 9 to the upper end notch of the slide slot 1 201, thereby stretching the telescopic connecting rod structure 17 and driving the electric telescopic rods 9 on both sides to move in the opposite direction synchronously. At this time, the electric telescopic rod 9 is retracted, and the indentation length adjustment is completed.

[0027] Then start the motor 6 and drive the reciprocating screw 5 to rotate, thereby driving the connecting plate 8 to slide back and forth on the reciprocating screw 5 to determine the indentation position of the indentation knife unit 7. After the position is determined, turn off the motor 6 and start the hydraulic cylinder 4. The telescopic end of the hydraulic cylinder 4 extends out and drives the lower pressure plate 3 to press down, thereby driving the indentation knife unit 7 to indent the paper.

[0028] By toggling the electric telescopic rod 9, the telescopic block 14 is adjusted to engage with the limiting hole 10 or the limiting hole 2 11, so as to adjust the knife holder 2 702 to extend or retract the knife holder 1 701, thereby realizing the free adjustment of the length of the creasing knife unit 7, and thereby controlling the length of the creasing, which can not only realize the creasing processing of papers of different widths, but also meet the work of local creasing.

[0029] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
