Description

Technical Field

[0001] The invention relates to corrugated paper box production equipment, in particular to a corrugated paper slotting device. Background Art

[0002] Corrugated box production equipment usually includes a paper feeding unit, multiple printing units, a creasing unit, a slotting unit, a die-cutting unit, a folding and gluing unit, etc. Each component unit works in a coordinated manner under the action of the power system and transmission system to complete a series of processing operations such as paper feeding, multi-level printing, creasing, slotting, die-cutting, folding, and gluing of corrugated cardboard.

[0003] Among them, in the slotting process, a slotting mechanism is used to cut a broken slot at a specified position of the corrugated paper so as to be folded later to form a three-dimensional carton. For example, the slotting unit disclosed in the invention application with application publication number CN117754915A includes a matching upper slotting unit and a lower slotting unit, wherein the upper slotting knife of the upper slotting unit is arranged at the lower part of the upper fixed plate, and the upper slotting knife includes a cutter wheel, a cutter wheel shaft, an eccentric gear, an adjustment transmission gear and an adjustment shaft, and the cutter wheel and the eccentric gear are coaxially arranged on the cutter wheel shaft, and the adjustment transmission gear is The movable gear is meshed and connected with the eccentric gear, and the adjusting shaft is arranged in the middle of the adjusting transmission gear; wherein, the eccentric gear, the adjusting transmission gear and the adjusting shaft constitute the above-mentioned eccentric gap adjustment component, which can adjust the gap between the upper slotting knife and the lower slotting knife to adapt to the different slotting processing requirements of the corrugated cardboard; when it is necessary to adjust the gap between the upper slotting knife and the lower slotting knife, the adjusting shaft is driven, the adjusting shaft drives the transmission gear to rotate, and the transmission gear drives the eccentric gear to rotate, and under the action of the eccentric gear, the cutter wheel shaft and the cutter wheel rotate synchronously and are adjusted up and down.

[0004] The above slotting mechanism has the following disadvantages:

[0005] After adjusting the transmission gear to drive the eccentric gear for lifting and lowering, the transmission gear and the eccentric gear are adjusted to stop rotating, so that the cutter wheel shaft and the cutter wheel stay at the current height, thereby completing the lifting and lowering adjustment. It can be seen that the height locking of the cutter wheel shaft and the cutter wheel is achieved by adjusting the meshing between the transmission gear and the eccentric gear; among them, since the meshing between the gears is a transmission relationship between two mechanical parts, it is not a firm connection relationship, and the transmission gear and the eccentric gear are adjusted to be distributed vertically, so during the processing, the eccentric gear may shake or move, causing the cutter wheel shaft and the cutter wheel to jump, and the stability is poor, which not only affects the slotting quality, but also makes a lot of noise, which needs to be improved.

[0058] See also Figure 1-3 and Figure 6 The working principle of the above-mentioned corrugated paper slotting device is as follows:

[0059] When working, the conveying mechanism takes over the corrugated paper from the previous processing station and conveys it downward; during the conveying process, the upper slotting cutter wheel 6 and the lower slotting cutter wheel 7 cooperate to shear the designated part of the corrugated paper, thereby forming a broken groove.

[0060] Further, if the height of the upper slotting cutter wheel 6 needs to be adjusted, the cutter wheel height adjustment screw 14 is driven to rotate by the cutter wheel height adjustment drive motor 12, and the cutter wheel height adjustment screw nut drives the cutter wheel height adjustment plate 11 to move vertically, thereby adjusting the height of the upper slotting cutter wheel 6. The cutter wheel height adjustment screw 14 and the cutter wheel height adjustment screw nut cooperate to firmly fix the cutter wheel height adjustment plate 11 and the upper slotting cutter wheel 6 at the set height, with good stability and not prone to jumping, which is conducive to reducing processing noise and improving slotting quality.

[0061] The above is a preferred embodiment of the present invention, but the embodiment of the present invention is not limited to the above content. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
