Embodiment Construction

[0020] In the specific implementation of the present invention, the seamless die-cutting process of asynchronous feeding includes the following steps

[0021] First cut the four frame strips of a four-frame product, that is: use asynchronous cutting equipment to cut each frame strip and reserve a small amount of remaining material on a strip-shaped overall material according to the specifications of the frame strip; Transfer and peel off the release film; overlap the release film with four border strips to form the product frame, and the remaining material of the four border strips overlaps; use a single-piece cutter to cut the four border strips The overlapping part is cut by a single knife; rolling to achieve the same plane connection of the product frame strips to obtain a complete product; peel off the excess part of the release film. When overlapped and cut, the order of two adjacent border strips and release film from top to bottom when they overlap is release film, border ...

Abstract

The invention provides a die cutting technology achieving asynchronous feeding and seamless splicing purposes. The die cutting technology aims to overcome the technical defects that in the prior art, materials of cut products are wasted, seams are generated in splicing, and therefore the product yield is low. The die cutting technology can improve the material utilization rate of cut products and achieve seamless connection. The die cutting technology comprises the steps that firstly, four frame bars of a square product are cut out; secondly, the frame bars are attached to a release film which can be delivered and stripped; thirdly, the release film which the four frame bars are attached to is overlapped to form a product frame; fourthly, the overlaid parts of the four frame bars are cut through single cutters; sixthly, roll pressing is conducted to achieve coplanar connection of the product frame bars; finally, spare parts of the release film are stripped. Through the combination of the seamless asynchronous die cutting technologies, the four frame bars are connected seamlessly, so that materials are saved, dust is prevented from entering the product, and the functions of the product can not be affected.

Description

Technical field [0001] The invention relates to a production process of patch, more specifically, to a die-cutting process of asynchronous feeding and seamless splicing. Background technique [0002] In the prior art, die-cutting of thin products such as mobile phone protective films, computer protective films, electronic printing products, double-sided stickers, and aviation equipment requires precision equipment to operate. At present, there are a wide variety of die-cutting products on the market, and the industry has a great demand. However, although some existing die-cutting machines are equipped with multiple stations, each station performs the same processing action, that is, the The processed material strip is subjected to one-blade die cutting. This type of die cutting machine is suitable for single product processing. For some products that require large product sizes and low precision requirements, they are currently die-cut according to the whole set, which brings...
