Uncoiling process of winding coil material

Abstract

The invention relates to the field of disposable sanitary product production processes, in particular to an uncoiling process of a winding coil material. The uncoiling process mainly solves the problem that in the prior art, an uncoiling process of a narrow non-woven fabric winding coil material is adopted to reduce waste of joint wastes as the joints are relatively long and to lower the processing cost. The process comprises the following steps: (1) separately assembling two non-woven fabric winding coils on an unwinding device for emptying; (2) limiting the emptied non-woven fabrics througha round ring limiting device in an early stage; (3) realizing forward overturning of the limited non-woven fabrics at a clamping mechanism by means of clamping roller action on the clamping mechanismfirst and then realizing reverse overturning under the action of another clamping roller; (4) after overturning, arranging a flattening device to flatten the non-woven fabrics to remove folded wrinkles in the overturning process; and (5) carrying out sweat soldering on the flattened non-woven fabrics through a material breaking and connecting device.

Description

technical field [0001] The invention relates to the field of production technology of disposable sanitary products, in particular to an uncoiling process of winding roll materials. Background technique [0002] At present, the overall production speed of domestic disposable sanitary products equipment is getting faster and faster, most of which are close to 300 meters per minute, and are breaking through at a higher speed. Under this background, the roll diameter of the material has not increased, which means that the previous roll Materials that have been used up in 20 minutes may now be used up in 15 or 10 minutes, requiring one action to replace the material, resulting in waste of joint waste, or material breakage caused by human factors, which is not conducive to cost control. [0003] The traditional unwinding process is to set two unwinding rollers on the unwinding device, one of which works to unwind, and when the unwinding is almost completed, the other unwinding rol...
