Description

TECHNICAL FIELD

[0001] The utility model belongs to the composite paperboard processing equipment technical field, concretely relates to a kind of multilayer composite paperboard uniform gluing device. BACKGROUND

[0002] The existing gluing equipment cannot automatically supplement the used glue after gluing is completed, resulting in the need to stop the gluing equipment to supplement the glue, affecting automated production. The "high-edge-pressure-strength multilayer corrugated paperboard bonding processing device" disclosed in the application number "CN202320908862.9" is also a mature technology. The transmission belt drives the transmission roller to rotate, and the transmission wheel and the transmission belt drive the gluing roller to rotate, thereby driving the second bevel gear to rotate, which in turn drives the threaded rod to rotate. The threaded rod moves the internally threaded tube that is limited and cannot rotate, which in turn moves the piston upward. This can gradually push the glue in the liquid storage box upward into the glue box, and automatically supplement the glue into the glue box. However, the device still has the following defects: in actual use, the multilayer paper needs to be bonded on the corrugated paperboard, but currently only the surface of single-layer paper can be glued, which is not convenient for merging and bonding multiple papers, and the processing efficiency is not high. Moreover, when the glue is about to be used up, it cannot automatically remind to supplement the glue. During the gluing process, the glue is usually coated horizontally on the paper surface by a roller, but the excess glue will squeeze out of the paper, resulting in waste of glue. SUMMARY
