680 results about "Corrugated fiberboard" patented technology

Corrugated fiberboard is a material consisting of a fluted corrugated sheet and one or two flat linerboards. It is made on "flute lamination machines" or "corrugators" and is used in the manufacture of shipping containers and corrugated boxes.

Insulated shipping container and method of making the same

Insulated shipping container and method of making the same. In a preferred embodiment, the insulated shipping container comprises an outer box, an insulated insert, an inner box and a closure member. The outer box, which is preferably made of corrugated fiberboard, comprises a rectangular prismatic cavity bounded by a plurality of rectangular side walls, a closed bottom end, and top closure flaps. The insulated insert is snugly, but removably, disposed within the outer box and is shaped to define a rectangular prismatic cavity bounded by a bottom wall and a plurality of rectangular side walls, the insulated insert having an open top end. The insulated insert is made of a foamed polyurethane body to which on all sides, except its bottom, a thin, flexible, unfoamed polymer bag is integrally bonded. The bag is a unitary structure having a generally uniform rectangular shape, the bag being formed by sealing shut one end of a tubular member with a transverse seam and forming longitudinal creases extending from opposite ends of the seam. The inner box, which is snugly, but removably, disposed within the insert, is preferably made of corrugated fiberboard and is shaped to include a rectangular prismatic cavity bounded by a plurality of rectangular side walls and a closed bottom end, the top end thereof being open. The closure member is a thick piece of foam material snugly, but removably, disposed in the open end of the inner box.

Cutting device of corrugated board production line

ActiveCN111037632AReduced extrusion deformationReduce foaming and degummingMetal working apparatusGear wheelElectric machinery
The invention discloses a cutting device of a corrugated board production line, and relates to the field of corrugated board production. The cutting device comprises a rack, wherein a cutting assemblyis arranged on the rack and comprises a mounting frame and two spiral cutters; the mounting frame is connected to the rack in a sliding mode in the conveying direction of corrugated boards, and the two spiral cutters are distributed up and down and are rotationally connected to the mounting frame; each spiral cutter comprises a rotating roller and a cutting edge; the rotating roller is rotationally connected to the mounting frame, and the cutting edge is arranged on the outer side wall of the rotating roller in the axial direction of the rotating roller; gears are fixed at one axial ends of the rotating rollers, and the two spiral cutters are meshed with each other through the two gears to synchronously rotate; a driving motor is further arranged on the mounting frame; and a transmissionassembly is further arranged on the rack, the transmission assembly is connected to one of the spiral cutters and drives the mounting frame to move in a reciprocating mode in the conveying direction of the corrugated boards through the rotation of the spiral cutters. According to the cutting device, the transmission assembly is arranged, and the spiral cutters move in the conveying direction during cutting, so that the situation that the corrugated boards on the front side are extruded and deformed during cutting is reduced, and the overall production is more stable.
