A servo independent transmission mechanism applied to a corrugated paper slotting machine

Abstract

This utility model discloses a servo independent transmission mechanism for a corrugated paper slotting machine, comprising a slotting cutter shaft. The key feature is that the slotting cutter shaft is directly driven by a servo motor and a gearbox; a slotting cutter disc is mounted on the slotting cutter shaft at intervals via a slotting cutter disc fixing component; and slotting cutters are mounted on the slotting cutter disc. The slotting cutter shaft of this utility model is directly driven by a servo motor and a gearbox, allowing adjustment of the linear speed of the slotting cutter shaft based on signals from a linear speed sensor, thereby adjusting the linear speed of the slotting cutter disc. This allows for convenient adjustment of the linear speed of the slotting cutter shaft when replacing 5-layer or 7-layer slotting cutter discs. Furthermore, by mounting the slotting cutters on the slotting cutter disc, damage or wear of the slotting cutters only requires replacement of the slotting cutters, eliminating the need to disassemble the slotting cutter disc and reducing replacement costs.

Description

Technical Field

[0001] This utility model relates to the technical field of corrugated paper slotting machines, and in particular to a servo independent transmission mechanism applied in corrugated paper slotting machines. Background Technology

[0002] Existing water-based corrugated paper printing presses use gear trains to drive the slotting blade shaft. When changing to 5-ply or 7-ply corrugated paper, the different diameters of the slotting blades on the cutter head result in varying cutting speeds, frequently causing the cardboard grooves to break. The most effective solution is to adjust the cutter head's linear speed. However, adjusting the slotting blade shaft's linear speed using gear trains is cumbersome. Without adjustment, the paper is easily torn during slotting, affecting the quality of the corrugated paper. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a servo independent transmission mechanism for corrugated paper slotting machines, which solves the problem that gear transmission makes it inconvenient to adjust the linear speed of the cutter.

[0004] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0005] A servo independent transmission mechanism for use in a corrugated paper slotting machine includes a slotting cutter shaft, characterized in that the slotting cutter shaft is directly driven by a servo motor and a gearbox; a slotting cutter disc is mounted on the slotting cutter shaft at intervals via a slotting cutter disc fixing component; and slotting cutters are mounted on the slotting cutter disc.

[0006] In a preferred embodiment of the present invention, the grooving cutter head is mounted on the grooving cutter shaft by a flat key and axially tightened onto the grooving cutter shaft by a cap.

[0007] In a preferred embodiment of the present invention, a plurality of screw holes are spaced apart circumferentially on the grooving cutter disc, the grooving cutter is an arc-shaped blade, and two waist-shaped grooves are provided on the grooving cutter. The blade fastening screw passes through the waist-shaped groove and is screwed into the corresponding screw hole to fix the grooving cutter on the grooving cutter disc.

[0008] Thanks to the above technical solution, the grooving cutter shaft is directly driven by a servo motor and a gearbox. The linear speed of the grooving cutter shaft can be adjusted based on the signal from the linear speed sensor, thereby adjusting the linear speed of the grooving cutter disc. If replacing a 5-layer or 7-layer grooving cutter, the linear speed of the grooving cutter shaft can be easily adjusted. Furthermore, by mounting the grooving cutter onto the grooving cutter disc, if the grooving cutter is damaged or worn, only the grooving cutter needs to be replaced; there is no need to disassemble the grooving cutter disc, thus reducing replacement costs.

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0013] See Figures 1 to 3 The figure shows a servo independent transmission mechanism used in a corrugated paper slotting machine, including a slotting knife shaft 100. The slotting knife shaft 100 is directly driven by a servo motor 200 and a gearbox 600. The linear speed of the slotting knife shaft 100 can be adjusted according to the signal given by the linear speed of the paperboard detected by the linear speed sensor, which is more convenient than the previous solution of using a gear system to drive the slotting knife shaft 100.

[0014] A grooving cutter head 300 is mounted on the grooving cutter shaft 100 at intervals via a grooving cutter head fixing component. Grooving cutters 400 are mounted on the grooving cutter head 300. Specifically, the grooving cutter head 300 is mounted on the grooving cutter shaft 100 via a flat key 310 and axially tightened onto the grooving cutter shaft 100 via caps 320 and 330 (which constitute the aforementioned grooving cutter head fixing component). A plurality of screw holes 340 are circumferentially spaced on the grooving cutter head 300. The grooving cutter 400 is an arc-shaped blade with two oblong grooves 410. Blade fastening screws 500 pass through the oblong grooves 410 and are screwed into the corresponding screw holes 340, thus fixing the grooving cutter 400 onto the grooving cutter head 300. If the grooving cutter 400 is damaged or worn, only the grooving cutter 400 needs to be replaced; there is no need to disassemble the grooving cutter head 300, reducing replacement costs.
