Description

Telescopic jig for eliminating tolerance of discharged material belt

Technical Field

The invention relates to the field of die cutting jigs, in particular to a telescopic jig for eliminating tolerance of a discharging material belt.

Background

At present, a die-cut product can be produced by mutually adhering, die-cutting and stripping various coiled material raw materials in the mass production stage, and finally the die-cut product is obtained. The width of the web stock material is greater than the die cut product by a cut tolerance, which is the difference in width between the shipping web and the final die cut product. It is generally necessary to add one more die cutting step to trim the edges of the web until the width of the die cut product is reached. The semi-finished product must therefore be passed through the die-cutting machine again to eliminate this tolerance, resulting in increased product man-hours and more occupied die-cutting machines and workers.

Although the existing solution can use a jig with blades to replace a high-cost die-cutting machine, how to adapt to material belts with various widths, how to stabilize the blades during die-cutting, and how to quantitatively adjust the blade spacing are problems that are often ignored by the skilled person.
