Application of laser cutting machine in leather industry
As a new machining method, laser cutting machine has been widely used in leather, textile and garment industry because of its precise processing, quick operation, simple operation and high automation.
Cutting laser cutting machine compared with the traditional not only low prices, low consumption. And because the laser processing has no mechanical pressure on the workpiece, so cutting out the effects of the products, precision and cutting speed are very good. And also has the advantages of safe operation, easy maintenance and so on. 24 hours continuously. Clean non-woven cloth cutting out laser machine edge not yellow, automatic edge fraying, not deformation, not hard, the same size and precise; it can be used to cut any complex shape; high efficiency and low cost, computer graphics design, it can be used to cut any shapes of various sizes. Because of the combination of laser and computer technology, users can design laser engraving output and change sculpture at any time as long as they are designed on computer.
The leather industry in an update, leather special laser cutting machine to break the traditional manual and cutting speed is slow and difficult to fully solve the problem of layout, the efficiency is not up to and waste materials. The laser cutting machine speed, simple operation, only need to be cut and the size of the input to the computer graphics, the machine will the whole piece of material cut into what you need products, without tools, need not die, non-contact processing by laser is simple and fast. For laser leather and bags enterprises and leather shoes, shoe production enterprises set cutting engraving machine, cutting, carving and hollowing in one, suitable for various leather processing: high-grade shoes, purses, leather cutting special shape, no burr, standard size, small error (+ 0.1mm), the effect of soft, high frequency or no die-cutting pressure blunt sense. Leather can be painted on the special effects or patterns, so that the finished products are more sophisticated and innovative.
In the field of industry applied to leather industry, mainly used for vamp carving, handbags, leather gloves, bags and so on. Some of the production process of small holes, surface hook line or cutting patterns, process requirements: hook line surface is not yellow, carved material background, leather cutting edge is not black, carving must be clear. The materials are synthetic leather, PU leather, PVC artificial leather, leather wool, semi-finished products, and all kinds of leather fabrics and so on. Engraving speed depends on the size of the graphics, small pattern line speed is relatively slow, the speed is 0.8 meters / minute, big pattern cutting speed is 1.5-3 meters / min. the light intensity is 75%, and the average leather can be cut through. Leather cutting slightly slower speed in 0.4-1.2 M / min, the intensity in 60-75%, leather cutting incision will be black, cut the air, but the incision will form the oxide layer, the dermis requirements such as incision not black, it is difficult to meet the requirements; all must be processed, such as cutting out can use plasticine the edge of the black with go. And cut it out of smell, so far, there is no way to solve it. The use of nitrogen cutting requires the use of high-pressure nitrogen, slow speed, high cost, but cutting oxide free, cutting effect a little better. Different leather materials, the choice of different cutting methods, such as artificial leather marking, you can first wet water before marking, the effect is more satisfactory. Leather cutting surface can be added to the United States and India paper, to prevent the yellow surface, black edges, the need for special treatment.
