Description

Technical Field

[0001] The utility model relates to the technical field of honeycomb paperboard processing, in particular to a honeycomb paperboard pressing machine. Background Art

[0002] Honeycomb paper is made according to the principle of natural honeycomb structure. It is made by connecting corrugated paper into countless hollow three-dimensional regular hexagons by gluing to form an integral load-bearing member, and gluing surface paper on both sides to form a new type of environmentally friendly and energy-saving material with a sandwich structure. Therefore, after the gluing process of the cardboard, it needs to be pressed to ensure the overall strength of the honeycomb cardboard.

[0003] However, during the pressing process of the honeycomb panels, some existing devices only move the pressing plate by extending and retracting the hydraulic rod, resulting in a pressure around the pressing plate being different from a pressure in the middle of the pressing plate, thereby affecting the pressing effect of the corners of the honeycomb panels and affecting the quality of the honeycomb panels.

[0013] Through the above technical solution, the two third sliders can be moved in opposite directions by rotating the bidirectional threaded rod, thereby driving the fixed plate to move, and the fixed plate drives the second slider to move, thereby moving the side baffle.

[0014] As a further improvement of the above solution, two third sliders are provided, and the two third sliders are symmetrically arranged around the center of the operation box.
