[0057] The rack 1 is fixed on the ground in a vertical manner, and a hydraulic cylinder one 11 for driving the mechanical arm 2 to lift is arranged on the rack 1, the shell of the hydraulic cylinder one 11 is fixed on the rack 1, and the output end is fixedly connected with one end of the mechanical arm 2; a mounting plate 8 is rotatably arranged on the other end of the mechanical arm 2, wherein a pull rod 21 extending in a vertical manner is rotatably connected with the mechanical arm 2, the bottom end of the pull rod 21 is fixedly connected with the mounting plate 8, and a rotating part 22 for driving the mounting plate 8 to rotate is arranged on the mechanical arm 2; the driving part 42 can be a servo motor, the shell of the servo motor is fixed on the top of the mechanical arm, and the output end is coaxially fixedly connected with the rotating rod 22.

[0058] The cutting mechanism 4 is used for die cutting the stacked paper sheets into a specific shape, so that the paper sheets can be folded into a box; the cutting mechanism 4 comprises a cutter 41 and a driving part 42 for driving the cutter 41 to vertically lift, the driving part 42 is movably arranged on the mounting plate 8, and the driving part 42 is arranged as a hydraulic cylinder two, the shell of the hydraulic cylinder two is movably arranged on the upper portion of the mounting plate 8, and the output end is fixedly connected with the top of the cutter 41.

[0059] Reference Figure 3 AndFigure 4 A positioning mechanism 5 is arranged for positioning and fixing the stacked paper sheets, and comprises a vertical rod 51 rotatably arranged at the bottom side of the mechanical arm 2 by means of a bearing 80, a first spreader 52 and a second spreader 53 movably arranged on the vertical rod 51, and a stop plate 54 hingedly connected to the other ends of the first spreader 52 and the second spreader 53. The vertical rod 51 is coaxially arranged with the pull rod 21, and the stop plate 54 is coated with a material with low friction on the bottom wall, such as a Teflon coating.

[0060] In one embodiment, the first spreader 52 and the second spreader 53 are directly hingedly connected to the two opposite outer walls of the vertical rod 51, so that the movable ends thereof can move in directions away from each other to slide and flatten the middle part of the paper sheet and fix the same.

[0061] In a second embodiment, the stop plate 54 can be omitted, and the first spreader 52 and the second spreader 53 are made of a flexible material such as a rubber strip, and the fixing of the paper sheet is achieved by the elastic abutting of the first spreader 52 and the second spreader 53.

[0062] In this embodiment, with reference to Figure 4 To ensure that the abutting of the stop plate 54 and the paper sheet will not cause damage to the paper sheet due to excessive abutting force, a limiting cylinder 55 is fixedly arranged on the vertical rod 51, and a connecting cylinder 56 is movably arranged on the outer periphery of the limiting cylinder 55. The height of the limiting cylinder 55 is greater than that of the connecting cylinder 56, and a limiting groove 551 is formed in the outer wall of the limiting cylinder 55 for limiting the connecting cylinder 56 from sliding off the limiting cylinder 55. One end of the first spreader 52 and the second spreader 53 is hingedly connected to the two opposite outer walls of the connecting cylinder 56, and the other end thereof achieves the effect of elastic abutting with the stacked paper sheet by means of the stop plate 54.

[0063] In addition, a spring 552 is further arranged on the outer periphery of the limiting cylinder 55, and the spring 552 is located between the upper end of the connecting cylinder 56 and the limiting cylinder 55. The spring 552 can provide a pushing force for the limiting cylinder 55 to approach the paper sheet, so that when the stop plate 54 abuts against the paper sheet, the connecting cylinder 56 can have a relative displacement allowance with the limiting cylinder 55, and will not cause damage to the paper sheet when abutting against the same.

[0064] Of course, in other embodiments, in order to improve the fixing effect of the stop plate 54 on different positions of the paper sheet, the above-mentioned limiting groove 551 can also be formed as a ring groove extending along the outer periphery of the limiting cylinder 55. The ring groove is concentrically arranged with the limiting cylinder 55, and the height of the ring groove along the axis of the limiting cylinder 55 is greater than the height of the connecting cylinder 56. At the same time, the top end of the spring 552 is fixedly connected to the limiting cylinder 55, and the bottom end thereof abuts against the connecting cylinder 56, so that the connecting cylinder 56 can rotate along the limiting cylinder 55 to achieve the effect of abutting the stop plate 54 against different positions of the paper sheet.

The outer wall of the limiting disk 57 abuts against the side walls of the first expansion strip 52 and the second expansion strip 53 facing each other, so that the first expansion strip 52 and the second expansion strip 53 are slightly open in a "V" shape, so that they will not interfere with the paper surface perpendicularly when descending, causing damage to the paper surface.

[0066] Reference Figure 2 and Figure 3 The telescopic mechanism 6 is used to drive the cutting mechanism 4 to move closer to or further away from the positioning mechanism 5, so that the cutter 41 can meet the cutting of different packaging box shapes. The telescopic mechanism 6 includes a slider 61 and an electric telescopic rod 62. The slider 61 is set as an "I"-shaped slider 61. The top wall of the mounting plate 8 has a groove 81 along its length direction for the slider 61 to slide and to fit the lower half of its I-shape. The groove 81 does not extend to the side end of the mounting plate 8, so that the slider 61 will not slip off from the groove 81. The housing of the electric telescopic rod 62 is fixedly installed on the side end of the mounting plate 8, and its telescopic end is fixedly connected to the slider 61.

[0067] Reference Figure 2 In order to remove paper scraps from the surface of the cutter 41 after cutting, a chip removal component 9 is also provided on the slider 61.

The ends of the door panels 71 that are close to each other are arc-shaped. The platform 3 is a frame structure, with the bottom wall of the door panels 71 abutting against the top wall of the platform 3 frame. The pushing component 72 pushes the door panels 71 open until their upper surfaces are tilted, allowing the cut waste paper scraps and scraps swept off the cutter 41 by the brush bristles 93 to fall along the tilted top surface of the door panels 71. Alternatively, collection boxes (not shown) can be installed on both sides of the platform 3 corresponding to the door panels 71 to collect and process the falling scraps.
