Method and device for producing honeycomb aluminum core

Abstract

The invention discloses a method for producing a honeycomb aluminum core, which belongs to the field of honeycomb core manufacturing. The surface of the aluminum foil is coated with glue; the cutting step: cutting the double-layer / multi-layer aluminum foil to form aluminum foil strips; the bonding step: bonding a plurality of aluminum foil strips to form a honeycomb aluminum core; The aluminum core is stretched and deformed to form a honeycomb aluminum core. By applying the aluminum foil to the honeycomb core, the structural strength and connection and dismounting strength of the honeycomb core are improved; the invention also discloses a production device of the honeycomb aluminum core, which improves the production efficiency and product quality of the honeycomb aluminum core.

Description

technical field [0001] The invention relates to the field of manufacturing a honeycomb core, in particular to a production method and device for a honeycomb aluminum core. Background technique [0002] At present, in the fields of splash materials, prefabricated houses, decorative materials, automotive materials, air purification and other fields, the requirements for the structure of the board are getting higher and higher, and it is necessary to reduce the weight and production cost while maintaining the structural strength, while the honeycomb structure board is To meet this requirement, honeycomb panels are generally made of a honeycomb paper core layer (subsequently called honeycomb paper core) and two pressure plates bonded to the upper and lower surfaces of the honeycomb paper core. Honeycomb paper core is a bionic structure product, which is manufactured according to the structural characteristics of honeycomb nests. Each honeycomb unit inside is closely connected, a...

Problems solved by technology

[0004] (1) The honeycomb paper core uses liner paper as the production material, and the flame retardant performance of the honeycomb paper board depends entirely on the pressure plate on the surface of the honeycomb paper core. If the honeycomb paper core inside the honeycomb paper core catches fire, the fire will burn along the honeycomb paper core until Completely burning the honeycomb paper core has serious fire safety hazards;

[0005] (2) The traditional honeycomb paper core manufacturing is to apply ordinary glue on the liner paper by hand or equipment and bond the mentally retarded in turn, and then cut the honeycomb paper core according to the thickness requirements of the honeycomb paper core. The thickness is difficult to be unified, and the cumbersome process also reduces the production efficiency of the honeycomb paper core;

[0006] (3) Since the honeycomb paper core is made of liner paper, which has strong elastic strength, even if the honeycomb paper core is stretched and shaped, as the use time goes by, the honeycomb paper core will gradually be stretched between the two press plates. Shrinkage, because the outer edge of the honeycomb paperboard is inlaid with the edge strips of the board, so if the honeycomb paper core shrinks after the honeycomb paper core is placed in the press plate, the inner honeycomb paper core cannot be stretched again. In the honeycomb paperboard, it is impossible to ensure that the honeycomb paper core fills the internal space of the board, resulting in a greatly reduced quality and performance of the honeycomb paperboard

[0007] (4) The traditional honeycomb paper core manufacturing method is difficult to ensure that the staggered width of the glue lines between the paper layers is consistent, and it is also difficult to ensure the accuracy of the bonding and positioning between the paper layers during the stacking and bonding process, and it is due to the multiple The paper cores are stacked and bonded and then cut uniformly. Therefore, the thickness of the stacked paper layers makes the cutting process easy to cause the honeycomb paper core to be pressed to deformation by the cutter, which affects the quality of the honeycomb paper core.
