AI Technical Summary
In the corrugated cardboard production line, the cardboard conveyed side by side is prone to collision and swing direction changes during the conveying process, affecting normal stacking. When stacking on the same pile of paper tables, the cardboards are close to each other and easily collide.
A stacker cardboard guide mechanism is designed, including a cardboard output channel and a guide block, which is used to guide two pieces of cardboard side by side in the longitudinal conveying process to be separated relative to the transverse direction. The cardboard output channel consists of the front upper layer output section, the front lower layer output section, the combined layer transition section and the tail output section. The transition table is driven connected to the lifting drive device, and the guide block is located in the combined layer transition section.
Through the guidance of the guide block, the chances of side-by-side cardboards touching each other on the same output channel are reduced, ensuring that the cardboards can be stacked side by side on the stacking table at the same time, reducing the risk of collision during the transmission process. At the same time, the design of the transition table realizes efficient convergence and stacking of cardboards, reducing space and energy consumption.

Abstract
Description
Technical Field
[0001] The utility model relates to a corrugated paperboard production device, in particular to a paperboard guiding mechanism of a stacking machine. Background Art
[0002] In the current corrugated cardboard production line, if a multi-layer cross-cutting machine is equipped, a corresponding number of paper discharge platforms need to be configured behind the multi-layer cross-cutting machine, and a corresponding paper stacking platform needs to be set behind each paper discharge conveying platform. In the corrugated cardboard production line, the cardboard is formed by the double-faced machine and then enters the longitudinal cutting machine. The longitudinal cutting machine cuts the cardboard longitudinally along the direction of movement of the cardboard. The longitudinally cut cardboard enters the corresponding layer of cross-cutting machines for transverse cutting, and finally passes through the corresponding paper discharge conveying platforms and is sent to the corresponding paper stacking platforms for counting and stacking.
[0003] Because the same length of cardboard is usually arranged on the same horizontal (width) during production, the cardboards of equal length can actually be stacked on the same cardboard stacking table after cutting. However, the cardboards distributed horizontally are very close to each other and are transported on a paper delivery table at the same time, which may cause the cardboards distributed horizontally to collide with each other and change their direction during transportation, affecting normal stacking; in addition, because the cardboards distributed horizontally are stacked on the same paper delivery table at the same time, the cardboards are very close to each other, which may cause the cardboards output from the paper delivery table to collide with each other, affecting stacking.

In combination with Figure 8 shown, when looking in the direction of the F arrow for the longitudinal conveyance of the cardboard, the initial gap between the two side-by-side cardboard 10 is L1. After one cardboard is guided by the guiding slope 11 of the guiding block 1, it is laterally offset outward in the direction of the T arrow, and then corrected to a straightened state through the maintaining straight surface 12. Finally, the gap between the two side-by-side cardboard is increased to L2. At the same time, the two cardboard at this time enter the same tail cardboard conveying table 7, and then jointly enter the stacking table 8 for stacking respectively.
