Selvedge trimming device of folding coiler

Abstract

The invention relates to an edge cutting device of a doubler, in particular to an edge cutting device of a doubler blade, which can improve the doubled edge cutting quality of aluminum foil and reduce the use cost for an edge cutting tool. The invention belongs to the edge cutting device technical field. The edge cutting device of the doubler comprises a tool post 1 fixed on a cross beam 5; the device is characterized in that: a wafer 2 is fixed on the tool post 1; a tool post protecting hood 8 is arranged on the wafer 2; an opening of the tool post protecting hood 8 is provided with a rotation retaining plate 7; and a blade 9 is fixed on the wafer 2. The edge cutting device of the doubler can adjust or fix a use angle of the blade, controls a cutting depth and a centerline of a cutter groove in a certain scope for normal use and makes the tool adjusting operation simple and efficient; a cutting edge of the blade falls on the centerline of the cutter groove of a cutting shaft, and can not cause the abrasion of the cutting edge of an edge cutting shaft of the doubler; the edge cutting device adopts a cheap blade for edge cutting, avoids the cutting tool from re-grinding and reduces the use cost for the edge cutting tool; the end face of the doubled aluminum foil is very smooth and flat and has no disadvantages of burr, aluminum crumb, etc.; and the aluminum foil has high quality of edge cutting and is favorable for doubled rolling.

Description

1. Technical field [0001] The invention relates to an edge trimming device of an unwinding machine, in particular to an edge trimming device of an unwinding machine blade capable of improving the quality of aluminum foil double trimming and reducing the use cost of edge trimming tools, and belongs to the technical field of edge trimming devices. 2. Background technology [0002] At present, the existing German CommScope double-coiling machine adopts the disc knife trimming method, which requires moderate pressure, and the gap between the knife groove and the lower knife shaft must be adjusted. The disc knife edge must be smooth, sharp, and non-existent. For defects such as chipping and burrs, the cutting edge must be continuously dripped with oil for lubrication and cooling during operation. Otherwise, defects such as burrs and aluminum chips will occur at the edge of the aluminum foil, which will cause strip breakage during double rolling. It is difficult to control the cutting ...

Problems solved by technology

[0002] At present, the double-fold aluminum foil of the existing German CommScope coiler adopts the disc knife trimming method, which requires moderate pressure, and the gap between the knife groove and the lower knife shaft must be adjusted. The disc knife edge must be smooth, sharp, and For defects such as chipping and burrs, the blade must be continuously dripped with oil to lubricate and cool down during work, otherwise defects such as burrs and aluminum chips will occur on the edge of the aluminum foil, resulting in broken strips during double-rolling

It is difficult and expensive to control the quality of edge trimming with disc knives, and the regrinding quality of disc knives is not easy to control
