Sheet-fed printing material cold-waving membrane-saving unit, cold-waving method thereof and sheet-fed printing material cold-waving membrane-saving device

Abstract

The invention discloses a sheet-fed printing material cold-waving membrane-saving unit, a cold-waving method thereof and a sheet-fed printing material cold-waving membrane-saving device. The sheet-fed printing material cold-waving membrane-saving unit comprises an unwinding mechanism, a winding mechanism and a control system. The unwinding mechanism comprises an unwinding roller used for unwinding at least two rolls of cold-waving membranes, and at least two first traction mechanisms used for traction of corresponding rolls of cold-waving membranes. The winding mechanism comprises a winding roller used for winding at least two rolls of cold-waving membranes. The unwinding roller and the winding roller are both slip frequency shafts. The unwinding mechanism, the winding mechanism and the first traction mechanisms are electrically connected with the control system. By means of the sheet-fed printing material cold-waving membrane-saving unit, the cold-waving method of the sheet-fed printing material cold-waving membrane-saving unit and the sheet-fed printing material cold-waving membrane-saving device, an existing whole-breadth cold-waving membrane which is used can be divided into multiple rolls of independent cold-waving membranes, each roll is independently driven, the cold-waving membranes can be effectively saved, aluminum resources can be effectively saved, and the material cost is reduced.

Description

technical field [0001] The invention relates to the field of printing machinery, in particular to a film-saving unit for cold ironing of a single printed material, a cold ironing method thereof, and a film-saving device for cold ironing of a single printed material. Background technique [0002] With the rapid development of light industry, packaging and printing industry, the application of cold stamping process is becoming more and more extensive. The use of sheet-fed printing material cold stamping device can process perfect patterns on printed materials such as paper or plastic sheets, increasing the visual effect of products and beautifying them. Life. Traditionally, when printing printed matter, the width of the cold stamping film is the same as the width of the product to be printed, and many parts to be printed that require hot stamping may only have a small area. In the case of many blank spaces in the printed matter, a lot of cold stamping will be wasted Membrane ...

Traditionally, when printing printed matter, the width of the cold stamping film is the same as the width of the product to be printed, and many parts to be printed that require hot stamping may only have a small area. In the case of many blank spaces in the printed matter, a lot of cold stamping will be wasted Membrane materials increase the cost of use
