Description

Technical Field

[0001] This utility model relates to the field of cardboard box slotting machine technology, and in particular to a surface slotting machine for packaging cardboard box production. Background Technology

[0002] In existing technology, packaging cartons are made of paper products and are used to package various items. They are divided into single-wall, double-wall, triple-wall, and quadruple-wall cartons. Cartons are further subdivided into paper boxes, color boxes, color cartons, and extra-large odd-shaped die-cut boxes. During the production of cartons, in order to make the cartons completely sealed, several grooves need to be cut at the top and bottom ends of the cardboard. At this time, a slotting machine is needed to perform slotting processing on the packaging carton board. When existing slotting machines are working, they drive two or more slotting wheels or drill bits to rotate through a rotating shaft. The slotting process is performed by rotating the slotting wheels or drill bits. However, a large amount of paper scraps are generated during the slotting process. The paper scraps accumulate on the packaging carton board, affecting the slotting progress and slotting effect of the cardboard, which is not conducive to subsequent slotting operations.

[0003] Chinese utility model patent application number 202223307270.6 discloses a surface grooving machine for producing packaging cartons, relating to the technical field of carton grooving machines. The machine includes a base plate and a grooving unit; the upper surface of the base plate is provided with a limiting component, a moving unit, and a top plate; the grooving unit includes an electric push rod, a mounting frame, a slide groove, a slide rod, a slider, a motor, a grooving knife, a locking groove, and bolts. There are two electric push rods, both mounted on the moving unit. The telescopic ends of the two electric push rods are connected to the mounting frame. The mounting frame is provided with a slide groove and a locking groove. The slide groove connects to the locking groove, and a slide rod is provided within the slide groove. The slider is slidably connected to the slide rod. However, although this surface grooving machine for producing packaging cartons can effectively limit and fix the packaging cartons, a large amount of paper scraps generated during the grooving process accumulate on the packaging carton board, affecting the grooving progress and effect, and hindering subsequent grooving operations.

[0035] Working principle:

[0036] When grooving is required on the packaging carton board, multiple sets of packaging carton boards are placed side by side on the upper end of the positioning base 2. The positioning screw 4 is rotated according to the specifications of the packaging carton board. The relative rotation between the positioning screw 4 and the positioning bracket 3 drives the relative movement of the two sets of positioning side frames 5 to clamp and position the packaging carton board. After positioning is completed, the equipment is started. The moving component is controlled by the electrical control unit 22 to move the positioning mechanism and the packaging carton board to the processing station. The blowing servo motor 16 is controlled to drive the blowing fan 17 to rotate at a certain angle to blow the grooving position of the packaging carton board. The grooving cylinder 19 drives the cutter head assembly to descend. The grooving motor 20 drives the grooving knife 21 to perform the grooving operation on the packaging carton board. During the grooving process, the blowing fan 17 blows away the paper scraps generated during the grooving process to prevent the paper scraps from accumulating on the packaging carton board.

[0037] The beneficial effects of this utility model are as follows: It is equipped with a positioning mechanism, which can simultaneously limit and fix multiple sets of packaging carton boards according to their specifications; and it can move the packaging carton boards via a moving component to meet the grooving processing requirements. It is also equipped with a blowing mechanism, which can adjust the angle of the blowing structure according to the position of the packaging carton boards, improving the blowing effect and preventing paper scraps generated during grooving from accumulating on the packaging carton boards, thus ensuring the grooving progress and effect. Furthermore, it is equipped with a grooving mechanism, which can cooperate with the positioning mechanism to simultaneously perform grooving operations on multiple sets of packaging carton boards, effectively improving processing efficiency.

[0038] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
