Sheet-fed printing material cold ironing film-saving unit and its cold ironing method, cold ironing film-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 single-sheet printing material cold stamping and film saving unit, a cold stamping method thereof, and a single-sheet printing material cold stamping and film saving device. Background technique [0002] With the rapid development of light industry and packaging and printing industries, the application of cold stamping technology has become more and more extensive. The cold stamping device for single-sheet printing materials can process perfect patterns on printed materials such as paper or plastic sheets, increase the visual effect of products, and beautify life. Traditionally, when printing printed matter, the width of the cold foil film is the same as the width of the product to be printed, and many products to be printed may only have a small area where hot stamping is required. When there are many blank spaces in the printed matter, a lot of cold foiling will be wasted The me...

Problems solved by technology

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
