Embodiment Construction

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

[0021] Cut the four frame strips of a four-frame product first, that is: use asynchronous cutting equipment to cut each frame strip according to the specification of the frame strip on a strip of overall material and reserve a small amount of surplus material; attach the frame strip to the available On the release film that is conveyed and peeled off; the release film with four frame strips is overlapped to form a product frame, and the remaining parts of the four frame strips overlap; a single-piece cutter is used to cut the four frame strips Cut the overlapping part with a single knife; roll to realize the same plane connection of the product frame strips to obtain a complete product; peel off the excess part of the release film. When overlapping and cutting, the order from top to bottom of two adjacent frame strips...

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, relates to a die-cutting process of asynchronous feeding and seamless splicing. Background technique [0002] In the prior art, precision equipment is required to die-cut thin products such as mobile phone protective film, computer protective film, electronic printing products, double-sided stickers, and aviation equipment. At present, there are various die-cutting products on the market, and the demand of the industry is very large. However, although some existing die-cutting machines are equipped with multiple stations, each station performs the same processing action, that is, the The processed strips are die-cut with one knife. This die-cutting machine is suitable for processing a single product. For some products that require large product size and not very strict precision requirements, they are still die-cut as a whole set at present, which brings certain advantages to th...
