Line pressing and slotting system for corrugated board printing machine

Abstract

The invention relates to a line pressing and slotting system for a corrugated board printing machine. The line pressing and slotting system comprises a line pressing machine and a slotting machine, wherein the slotting machine is located on one side of the discharge end of the line pressing machine, the line pressing machine comprises a line pressing machine frame (1), a line pressing paperboard feeding pinch roller (2), a line pressing paperboard discharging pinch roller (3), a plurality of upper line pressing wheel sets, a plurality of lower line pressing wheel sets cooperating with the upper line pressing wheel sets for use, and a plurality of line pressing wheel set driving motors (4), the slotting machine comprises a slotting machine frame (15), a slotting paperboard feeding pinch roller (16), a plurality of slotting wheel sets, a plurality of paperboard supporting wheel sets cooperating with the slotting wheel sets for use, a slotting machine driving motor (17) and a plurality ofslotting wheel set driving motors (18). The line pressing and slotting system has the advantage that the line pressing part and the slotting part are independently adjusted and moved, and the distances between bases are adjusted separately by the corresponding screw rods, so that the precision of the line pressing and slotting positions is maintained, and the technical requirements of automatic packaging are met.

Description

technical field [0001] The invention relates to the technical field of corrugated cardboard printing, in particular to a crimping and slotting system of a corrugated cardboard printing machine. Background technique [0002] At present, the creasing part and the slotting part of the existing corrugated board printing machine are integrated, and the creasing wheels and slotting discs of the creasing part and the slotting part cannot be adjusted separately. At present, most of them are automatic packaging. The crimping position and slotting position in cardboard stacking should be staggered by a certain distance according to the packaging requirements. The existing integrated creasing and slotting machine cannot meet this process requirement, and at the same time it brings inconvenience to maintenance and replacement. Each crimping wheel or slotting disc of the slotting part is installed on the frame through the corresponding rotating shaft, and then the distance between each c...

Problems solved by technology

[0003] The purpose of the present invention is to aim at the present, the creasing part and the slotting part of the existing corrugated cardboard printing machine are integrated, and the crimping wheels and the slotting discs of the creasing part and the slotting part cannot be individually adjusted. Most of them are automatic packaging. In the cardboard stacking, the creasing position and the slotting position must be staggered by a certain distance according to the packaging requirements. The existing integrated creasing and slotting machine cannot meet this process requirement, and at the same time it brings inconvenience to maintenance and replacement. , each crimping wheel or slotting disk of the existing crimping and slotting part is installed on the frame through the corresponding rotating shaft, and then adjusts the spacing of each crimping wheel or slotting disc through the fork mechanism, and the rotating shaft While providing rotating power, it is also necessary to support the weight and working pressure of each crimping wheel or slotting disc. The rotating shaft is easy to bend, resulting in inconsistent creasing or slotting depth, which affects production quality. Long-term work of the fork mechanism is easy to cause wear. , affect the adjustment accuracy, frequent replacement of shift fork accessories increases production costs, the existing crimping part is formed by one-time molding, which easily breaks the cardboard and affects the quality of creasing. After the tip of the knife is worn, the knife needs to be replaced, resulting in waste. At the same time, the length of the trimmed edge material is too long, it is not easy to discharge, and it is easy to cause blockage. A crimping and slotting system for a corrugated board printing machine is provided.
