The structure of the pressing wheel assembly of a paper corner protection automatic coiling device

Abstract

The invention discloses a pinch roller assembly structure of paper corner protector automatic bending device. A paper corner protector is a long strip 90-degree bending paper tape; the upper end of a vertically arranged rotating shaft is perpendicular to a disc surface of a rotary disc and is mounted at the disc center of the bottom part of the rotary disc; a pinch roller assembly is arranged above a rotary disc assembly; a sliding block is configured at each of the four end parts of an inclined cross-shaped guide rail; a compression air cylinder is mounted on each sliding block; a driving pinch roller is mounted on a piston rod of each compression air cylinder; the input end of a guide slot is hinged to a bracket of the guide slot; the output end of the guide slot crosses over an inclined lower disc edge of the rotary disc and extends into the rotary disc. Feeding, bending and discharging of the device are all conducted automatically by a control device of a control unit, the manual operation is omitted, and a great deal of labor is saved; the condition that the structure gets stuck completely can be efficiently avoided; the device is compact in structure, fully utilizes the stroke heights of the rotary disc assembly and the pinch roller assembly, facilitates manual observation, and occupies a small area.

Description

technical field [0001] The invention relates to the field of packaging and stacking, in particular to the coiled stacking of elongated right-angle bending paper with corner protectors. Background technique [0002] The long strip right-angle bending paper corner is a common steel product packaging cardboard, its cross section is "L" shape, including two mutually perpendicular sides, one of which has multiple "V" shaped cuts at intervals , with the tip of the cut facing the "L" bend of the packaging board. The traditional right-angle bending packaging cardboard stacking is done by hand. The operator stacks the packaging cardboard layer by layer. The outer side of the upper layer of cardboard is close to the inner side of the lower layer of cardboard, and then bundled in groups of 20 or 10, and finally Stack the bundled packaging cardboard. [0003] Due to the irregular shape of the bundled packaging cardboard, it is necessary to stack the bundled packaging cardboard layer b...

AI Technical Summary

Problems solved by technology

[0003] Due to the irregular shape of the bundled packaging cardboard, it is necessary to stack the bundled packaging cardboard layer by layer in a rectangular box to prevent the stack from collapsing and facilitate transportation. However, it is also because of the bundled packaging cardboard. The shape of the packaging cardboard is irregular, and there is a large gap between the packaging cardboards when stacking, so the stacking in the box is not tight, and the boxes cannot be stacked in multiple layers, so as to prevent the upper box from collapsing the lower box and affecting the stacking space. The utilization efficiency is not high, and the storage of stacked boxes needs to occupy a lot of space
