Detailed Description

The following describes in further detail the embodiments of the present invention with reference to the drawings and examples. The following examples are illustrative of the invention but are not intended to limit the scope of the invention.

Referring to fig. 1-7, an embodiment of the present invention is provided: a carton grooving machine comprises a frame 1, wherein a conveying roller 100 for conveying a carton board is arranged on the frame 1, and the carton board is conveyed along the frame 1; the front end of the frame 1 is provided with a paperboard feeding mechanism 2, an indentation mechanism 3 and a cutter set mechanism are arranged in the paperboard conveying direction, and the cutter set mechanism comprises a plurality of groups of cutter modules 4 which are arranged in parallel.

The cutter module 4 comprises a cutter handle 40, a cutter guide rail 41 for providing movable support for the cutter handle 40, a cutter main body 42 fixed at the end part of the cutter handle 40, a cutter driving module 43 for driving the cutter handle 40 to reciprocate, and a cutter seat 44 arranged below the cutter main body 42 for providing cutting guide for the cutter main body 42, wherein the edge part of the cutter main body 42 is parallel to the paper board conveying direction.

In this embodiment, four sets of cutter modules 4 are provided. The cutter bodies of the three groups of cutter modules 4 are the same, and corner cutters 45 are convexly arranged at two ends of the cutter body 42 of the cutter module 4 at the most side. By the above-described arrangement of the cutter modules 4, it is possible to cut out a standard case 400 (see fig. 8), which standard case 400 includes ears 403 cut by the cutter body 42 of the cutter module 4 at the most side and the corner cutters 45 at both ends, notches 401 cut by the cutter body 42 of the cutter module 4 at other positions, and indentations 402 pressed by the indentation mechanism 3, and two indentation lines 404 perpendicular to the case height in the standard case 400 are obtained by pressing on a board production line.

In the above-described structure, the cardboard is conveyed in a direction parallel to the conveying direction along the box-height line (i.e., the crease 402 in fig. 8) to the creasing mechanism 3 to crease,

then the upper side of the cardboard box (the upper side is defined as the upper side in fig. 8), the upper side notch is cut by each cutter module 4 in the cutter module mechanism, and then the cardboard is continuously conveyed until the lower side position of the cardboard is aligned with the cutter module 4, and at the moment, the lower side notch is cut by the cutter module 4, namely, all notch cutting processing of the cardboard is completed by cutting twice by a group of cutter module groups, so that the number of parts of the whole device is greatly reduced, and the cost is reduced.

Preferably, the lateral position of the cutter module 4 is adjustable. The position of the cutting notch can be controlled by adjusting the transverse position of the cutter module 4, so that the boxes with different types can be manufactured; specifically, the cutter guide rail 41 is movably supported by a guide rod 200 that is transversely disposed, and a locking mechanism (shown in the drawing) is disposed on the guide rod 200 for locking the cutter guide rail 41 at the position of the guide rod 200, where the locking mechanism may be a locking cylinder, and the clamping component with a locking function may be a conventional locking structure, and the structure and principle parts thereof will be described in detail in this embodiment. Each cutter seat 44 is driven to move transversely by a transversely arranged screw mechanism 300, in the structure, the cutter main body 42 extends into the notch of the cutter seat 44, and at the moment, the cutter guide rail, the cutter handle, the cutter main body 42 and the cutter seat 44 follow; therefore, the position of the cutter holder 44 can be adjusted by outputting power from the screw mechanism 300, and the position of the cutter body following the cutter holder 44 can be adjusted, and when the cutter body is adjusted to a desired position, the position of the cutter guide rail can be fixed to the guide bar 200 by the lock mechanism.

Preferably, the indentation mechanism 3 comprises a lower pressing roller 30 and an upper pressing roller 31, a sleeve member 32 capable of sliding along the lower pressing roller is arranged on the lower pressing roller 30, and an indentation convex rib 33 matched with the shape of an indentation line is arranged on the sleeve member 32; the middle part of the sleeve member 32 is provided with a limit groove 34, the front section of the cutter seat 44 is provided with a claw 45, and the claw 45 is buckled into the limit groove 34 so as to fix the cutter seat 44 and the sleeve member 32. In the structure, the position of the cutter seat 44 is adjusted through the screw mechanism 300, and meanwhile, the position of the indentation mechanism 3 and the position of the cutter main body can be aligned, so that the procedure time for adjusting different cartons for grooving is greatly reduced.

Preferably, a pinch roller seat 46 is provided on an end surface of one end of the cutter guide rail 41, and pinch rollers 47 are provided at both ends of the pinch roller seat 46. The lower side of the pressing wheel 47 is higher than the lower end plane of the cutter body, when the cutter body cuts, the pressing wheel presses the cardboard box, so that the position of the cardboard box is prevented from shifting when the cutter body cuts the cardboard box, and after the cutting opening of the cutter body is completed, the pressing wheel 47 presses the cardboard box, so that the cardboard box can be prevented from being driven by the cutter body to move upwards.

Wherein, cardboard feeding mechanism 2 includes multiunit conveyer belt group 20 that the interval set up, the cardboard baffle 21 of the fixed setting in conveyer belt group 20 outside both sides, and the striker plate 22 that sets up in conveyer belt group 20 transport rear position, striker plate 22 drives its activity from top to bottom through a servo 23, and servo 23 controls the interval between striker plate 22 and the conveyer belt surface of conveyer belt group 20 between one to two carton thickness (not including the extreme point numerical value) to guarantee to nearly carry one cardboard at every turn. A scrap conveying belt wheel 5 is arranged at the issuing position of the frame 1 and is used for receiving scraps obtained by cutting the cardboard boxes by the cutter module.

Of course, the arrangement of the cutter modules in the present embodiment is not limited thereto, and the number and structure of the cutter modules can be specifically allocated according to the box shape to be cut, for example, the cutter modules 4 can be arranged in two groups, and the cutter body 42 of one group of cutter modules 4 is provided with corner cutters 45 protruding from two ends. This arrangement can be used to cut two box-in-box (see fig. 9); for another example, the cutter modules 4 are also arranged in two groups, and the two groups of cutter modules 4 are all common cutter mechanisms comprising a cutter main body 42; at this time, the top and bottom cover box type can be cut out (see fig. 10).

In addition, the slot-cutting machine in this embodiment can cut a carton with any height (which is not greater than the length of the whole frame), specifically, the edge of the cutter body 42 is parallel to the conveying direction of the cardboard. Therefore, when the paper box with the preset height needs to be cut, only the distance between the first time of cutting and the second time of cutting of the paper board by the cutter group mechanism needs to be controlled.

The foregoing is merely a preferred embodiment of the present invention, and it should be noted that it will be apparent to those skilled in the art that modifications and variations can be made without departing from the technical principles of the present invention, and these modifications and variations should also be regarded as the scope of the invention.
