Abstract

Disclosed are a honeycomb cell shock-protection paper pad structure, and a fabrication method and a fabrication apparatus, for overcoming springing back of a stretched honeycomb cell paper shock-protection pad. The honeycomb shock-protection paper pad structure includes paper strips that have an unconnected site of which upper and lower ends are formed with folded-edge bend portions and a connected site that is formed with a central bend portion. A shape-fixing method includes stretching a cellular-form shock-protection paper pad for extension, bending upper and lower ends of the paper strips of the stretched honeycomb cell shock-protection paper pad toward one side, and conducting shape-fixing rolling with paired rollers. A shape-fixing apparatus includes a chassis portion, an edge scraper portion including flexible upper and lower scraper blades mounted obliquely on the chassis portion, and a shape-fixing roller portion including rigid shaping paired roller mounted on the chassis portion.

Abstract

A honeycomb shockproof paper pad structure, a processing method, and a processing device. The honeycomb shockproof paper pad structure is composed of a group of paper strips (1) uniformly distributed and bonded together at intervals; the end surface of each paper strip (1) is of a honeycomb structure; and the upper and lower ends of each paper strip (1) are provided with folded edge bending portions (1-1) at non-bonding positions, and the paper strip (1) is provided with a middle bending portion (1-2) at a bonding position. A shaping method is implemented according to the following steps: step A1, stretching and expanding a contracted cell-based shockproof paper pad into a honeycomb shockproof paper pad (3); step A2, subjecting the honeycomb shockproof paper pad (3) to chamfering trimming while keeping tensile stress unchanged, so that the upper and lower ends of the stretched paper strip (1) bend and deform towards one side; and step A3, feeding the honeycomb shockproof paper pad (3) obtained in step A2 into a pair of paired rollers for shaping rolling. A shaping apparatus comprises a rack part (5), a scraping part, and a shaping rolling part. The scraping part comprises a flexible upper scraping piece (2-1) and a flexible lower scraping piece (2-2), the flexible upper scraping piece (2-1) and the flexible lower scraping piece (2-2) being obliquely fixed on the rack part (5); and the shaping rolling part comprises a rigid forming paired roller (4-1).

Abstract

An expanding machine includes a chassis, a feeding roller carrying a honeycomb paper, a guiding roller, and an expansion roller assembly including an upper expansion roller, a lower expansion roller, and a passage gap. The upper expansion roller includes upper projection assemblies that are staggered with respect to each other. Each of the projecting assemblies includes upper projecting portions and upper supporting portions that are alternate with respect to each other. The lower expansion roller includes projecting portions and supporting portions corresponding to the upper expansion roller. When the expansion roller assembly is put into rotation, the upper projecting portions correspond to the lower supporting portion, and the lower projecting portions correspond to the upper supporting portions, so that the projections that are separately arranged may pull and expand the honeycomb paper, making it not readily compress down the honeycomb paper or generating apparent compressing marking.
