[0030] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0031] Please see Figures 1-7 An embodiment of the present invention provides a cardboard box slotting machine, including a frame 1, on which a conveying roller 100 for conveying cardboard is provided, and the cardboard box is conveyed along the frame 1; a cardboard feeding mechanism 2 is provided at the front end of the frame 1, and a creasing mechanism 3 and a cutting knife group mechanism are provided in the cardboard conveying direction, wherein the cutting knife group mechanism includes multiple sets of parallel cutting knife modules 4.

[0032] The cutting module 4 includes a cutting handle 40, a cutting guide rail 41 that provides movable support for the cutting handle 40, a cutting body 42 fixed to the end of the cutting handle 40, a cutting drive module 43 for driving the cutting handle 40 to reciprocate, and a cutting seat 44 disposed below the cutting body 42 for providing cutting guidance for the cutting body 42, wherein the blade of the cutting body 42 is parallel to the paperboard conveying direction.

[0033] In this embodiment, the cutting module 4 is provided in four sets. Three sets of cutting modules 4 have identical cutting bodies, and the cutting body 42 of the outermost cutting module 4 has protruding corner cutting blades 450 at both ends. Through the above-mentioned distribution of the cutting modules 4, they can be used to cut out standard boxes 400 (see appendix). Figure 8 The standard box 400 includes ear portions 403 cut by the cutter body 42 of the cutter module 4 on the far side and the corner cutters 450 at both ends, grooves 401 cut by the cutter body 42 of the cutter modules 4 at other positions, and indentations 402 pressed by the indentation mechanism 3. The two indentation lines 404 in the standard box 400 that are perpendicular to the height of the box are pressed on the cardboard production line.

[0034] In the above structure, the cardboard box is marked with a box height line (i.e., attached). Figure 8 The indentation 402 is conveyed to the indentation mechanism 3 in a direction parallel to the conveying direction to create an indentation.

[0035] Then the top side of the cardboard box (with attachment) Figure 8The upper side of the paperboard is cut by each cutter module 4 in the cutter module mechanism to form an upper side notch, and then the paperboard is continuously conveyed until the lower side of the paperboard is aligned with the cutter module 4, at which time a lower side notch is cut by the cutter module 4, that is, all notch cutting of the paperboard is completed by two times of cutting by the cutter module, which greatly reduces the number of parts of the entire device and reduces the cost.

[0036] Preferably, the lateral position of the cutter module 4 is adjustable. By adjusting the lateral position of the cutter module 4, the position of the cutting notch can be controlled to manufacture different types of boxes. Specifically, the cutter guide rail 41 is movably supported by a transversely arranged guide rod 200, and a locking mechanism (not shown in the figure) is arranged on the guide rod 200 to lock the cutter guide rail 41 in position on the guide rod 200. The locking mechanism can be a locking cylinder, a clamping part with a locking function, or a conventional locking structure. In this embodiment, the structure and principle thereof will not be described again. Each cutter seat 44 is driven to move laterally by a transversely arranged lead screw mechanism 300. In the above structure, the cutter body 42 is inserted into the notch of the cutter seat 44, at which time the cutter guide rail, cutter handle and cutter body 42 move with the cutter seat 44. Therefore, the position of the cutter seat 44 can be adjusted by the output power of the lead screw mechanism 300, and the position of the cutter body moving with the cutter seat 44 can be adjusted. When the cutter body is adjusted to the required position, the position of the cutter guide rail on the guide rod 200 can be fixed by the locking mechanism.

[0037] Preferably, the indentation mechanism 3 includes a lower pressing roller 30 and an upper pressing roller 31. A sleeve 32 that can slide along the lower pressing roller is arranged on the lower pressing roller 30, and an indentation rib 33 matching the shape of the indentation line is arranged on the sleeve 32. A limiting groove 34 is arranged at the middle position of the sleeve 32. A claw 45 is arranged at the front end of the cutter seat 44, and the claw 45 is buckled into the limiting groove 34 to fix the cutter seat 44 and the sleeve 32. In the above structure, the position of the indentation mechanism 3 and the position of the cutter body can be aligned at the same time by adjusting the position of the cutter seat 44 by the lead screw mechanism 300, which greatly reduces the process time for adjusting different paper box cutting slots.

[0038] Preferably, a pressure roller seat 46 is arranged on one end face of the cutter guide rail 41, and pressure rollers 47 are arranged at both ends of the pressure roller seat 46. The lower side of the pressure roller 47 is higher than the lower end plane of the cutter body. When the cutter body cuts, the pressure roller presses the paperboard box to prevent the position of the paperboard from shifting when the cutter body cuts the slot. After the cutter body cuts the notch, the pressure roller 47 presses the paperboard box to prevent the paperboard box from being moved upward by the cutter body.

[0039] The paperboard feeding mechanism 2 comprises a plurality of groups of conveying belts 20 arranged at intervals, paperboard baffles 21 fixed outside the groups of conveying belts 20, and a blocking plate 22 arranged behind the groups of conveying belts 20 after the conveying, the blocking plate 22 being driven to move up and down by a servo mechanism 23, the servo mechanism 23 controlling the interval between the blocking plate 22 and the conveying belt surface of the groups of conveying belts 20 to be between one and two carton thicknesses (not including the end point value), so as to ensure that one paperboard is conveyed at a time. A waste conveying belt wheel 5 is arranged below the lower end of the frame 1, for conveying the waste obtained by cutting the paperboard carton by the cutting die module.

[0040] Of course, the arrangement of the cutting die module in the embodiment is not limited thereto, and the number and structure of the cutting die module can be allocated according to the specific type of the cut carton, for example, the cutting die module 4 can be arranged in two groups, and the cutting die body 42 of one group of cutting die modules 4 is provided with a cutting corner cutter 450 at both ends. This arrangement can be used to cut two-piece cartons (for example, FIG. 2). Figure 9 ); for another example, the cutting die module 4 is also arranged in two groups, and both groups of cutting die modules 4 are ordinary cutting die mechanisms comprising a cutting die body 42; at this time, a top-and-bottom cover carton (for example, FIG. 3) can be cut. Figure 10

[0041] In addition, the cutting slot machine in the embodiment can cut paper cartons of any height (as long as the length of the entire frame is not exceeded), specifically, since the blade of the cutting die body 42 is parallel to the conveying direction of the paperboard. Therefore, when a paper carton of a preset height needs to be cut, only the distance conveyed between the first cutting and the second cutting of the paperboard by the cutting die group mechanism needs to be controlled.

[0042] The above is only a preferred embodiment of the present application, and it should be noted that, for those skilled in the art, without departing from the technical principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered within the protection scope of the present application.​
