Telescopic jig for eliminating tolerance of shipment material belt

Abstract

The invention relates to a telescopic jig capable of eliminating the tolerance of a shipment material belt. The jig comprises a jig upper plate (1) and a jig lower plate (2), wherein the jig upper plate (1) is provided with blades (12) with adjustable intervals; the blades (12) are slidably connected with the jig upper plate (1); the jig lower plate (2) comprises middle grooves (22) with adjustable intervals; and when the jig is used, the jig upper plate (1) and the jig lower plate (2) are connected in a matched mode, a die cutting piece semi-finished product comprising a delivery material belt is located between the jig upper plate (1) and the jig lower plate (2). Compared with the prior art, the telescopic jig has the advantages of flexibility, adjustability, adaption to material belts of various widths, die cutting step saving and the like.

Description

technical field [0001] The invention relates to the field of die-cutting fixtures, in particular to a retractable fixture for eliminating tolerances of shipping material tapes. Background technique [0002] At present, in the mass production stage of die-cut products, various coil raw materials are bonded, die-cut, and peeled off, and finally die-cut products are obtained. Because the width of the raw material of the coil is compared with the die-cut product, there is a little more tolerance, and this tolerance is the gap between the width of the shipping material tape and the final die-cut product. It is generally necessary to add an additional die-cutting step to trim the edge of the strip until the width of the die-cut product is reached. Therefore, it is necessary to pass the semi-finished product through the die-cutting machine again to eliminate this tolerance, resulting in increased product man-hours and more die-cutting machines and workers. [0003] Although the e...

[0003] Although the existing solution can use a jig with a blade to replace a high-cost die-cutting machine, how to adapt to various widths of material tape, how to stabilize the blade during die-cutting, and how to quantify the distance between the blades Adjustment is a problem that is often overlooked by people in the field
