Single corrugated board production device

Abstract

The invention provides a single corrugated board production device, and belongs to the technical field of paperboard processing. The single corrugated board production device comprises a corrugated core board forming device, a gluing device, a cushion board conveyer device, a forming device, a temperature control device and a driving device; the corrugated core board forming device comprises an upper corrugated roller and a lower corrugated roller which are arranged in parallel up and down; the gluing device comprises a glue applicator; the forming device comprises a driving roller and a driven roller, an annular belt is connected between the driving roller and the driven roller; the cushion board conveyer device is arranged outside the forming device; the temperature control device comprises a temperature sensor connected with a temperature regulator; the driving device comprises an electric-pneumatic converter, the input end of the electric-pneumatic converter is connected with the temperature regulator, and the output end of the electric-pneumatic converter is connected with a cylinder. The single corrugated board production device provided by the invention is capable of controlling the produciton speed, controlling the bonding time and pressure and ensuring the temperature of a single corrugated board to be constant in the production process; furthermore, the single corrugated board production device is convenient to maintain and long in service life.

Description

technical field [0001] The invention relates to the technical field of cardboard processing, in particular to a single-face corrugated cardboard production device. Background technique [0002] The production of single-sided corrugated cardboard generally goes through processes such as corrugated core cardboard forming, glue coating, lining cardboard and corrugated core cardboard bonding, and molding, but there are some defects in the existing forming equipment. For example: the core paper forms corrugations in the gap after the upper and lower corrugating rollers engage with each other, the core paper is overlapped with the liner cardboard conveyed by another path, and the core paper and the liner are pressed together with the specified temperature and pressure Cardboard, such a single-sided corrugated cardboard is produced. However, as a pressurizing device is necessary equipment for bonding the paper of the above-mentioned raw materials, a part of the endless belt is in ...

AI Technical Summary

Problems solved by technology

[0003] Although the existing single-sided molding machine can adjust the molding pressure and molding time, it still has a defect, that is, it cannot maintain the bonding pressure between the corrugated peaks of the core paper and the liner, and it is very difficult to control; and the original technology The pitch circle diameters of the upper and lower corrugating rollers of the medium single-sided forming machine are the same and combined together, so it is very limited to increase the production speed

If the diameter of the upper and lower corrugating rollers is reduced to achieve the expected speed increase, the pressure bonding time will be shortened, so that the degree of bonding between the core paper and the liner will be insufficient; on the contrary, if the upper and lower corrugating rollers are increased If the diameter of the roll is used to avoid the above-mentioned defects, then not only the size of the whole device will become larger, but also the number of meshing teeth will increase, so the tension applied to the core paper that needs to be corrugated will become larger, and the core paper will be torn.
