Slotting unit for digital printing production line and slotting method thereof

Abstract

The invention discloses a slotting unit for a digital printing production line. The slotting unit for the digital printing production line comprises a machine body and two slotting devices, wherein aworking cavity is formed in the machine body, and the two slotting devices are oppositely arranged at the two ends of the working cavity. Each slotting device comprises a variable-speed slotting mechanism and an auxiliary slotting mechanism, wherein the variable-speed slotting mechanism comprises a slotting module and a variable-speed driving module. Each slotting module comprises a first rotatingshaft and a plurality of conveying rollers, wherein the conveying rollers are installed on the first rotating shaft at intervals. Each conveying roller comprises a conveying roller part mounted on the corresponding first rotating shaft and a slotting roller part rotationally arranged on the conveying roller part in a sleeving manner. Each variable-speed driving module is used for driving the corresponding slotting roller part to rotate on the conveying roller part at a constant speed or a variable speed. Each auxiliary slotting mechanism comprises a second rotating shaft and positioning rollers, wherein the second rotating shaft is correspondingly arranged below the first rotating shaft, and the positioning rollers are installed on the second rotating shaft at intervals. The slotting unitfor the digital printing production line and the slotting method of the slotting unit achieve high slotting efficiency.

Description

technical field [0001] The invention relates to the technical field of corrugated cardboard production, in particular to a slotting unit and a slotting method for a digital printing production line. Background technique [0002] Corrugated cardboard is a kind of packaging cardboard widely used in digital printing. In the digital printing production line, the existing corrugated cardboard is generally made into a continuous sheet of corrugated cardboard, which will be crimped and slotted according to the required size. , and finally made of corrugated cardboard with established specifications. For this reason, the equipment for grooving corrugated cardboard is an important part of the production of corrugated cardboard. The parts are grooved separately to distinguish the area of ​​the corrugated cardboard. The ungrooved part is the box body part, and the grooved part is the cover part. Form the box body, and then fold inwards several cover plates at both ends of the cover p...

AI Technical Summary

Problems solved by technology

[0003] However, in the existing corrugated cardboard slotting equipment in the digital printing production line, the slotting structure for slotting the corrugated cardboard keeps rotating at a constant speed. After slotting the corrugated cardboard, there is a long idle time. So that when several corrugated cardboards are placed on the slotting equipment in turn, the distance between adjacent corrugated cardboards should be longer, which corresponds to a longer idling time, but the efficiency of this slotting method is low and cannot Meet the needs of users
