Waste discharge system for die-cutting piece coarse product with holes

Abstract

The invention relates to a waste discharge system for a die-cutting piece coarse product with holes. The system comprises an outer frame, a contour waste discharge unit, a hole waste discharge unit and a material receiving unit, wherein the contour waste discharge unit, the hole waste discharge unit and the material receiving unit are all fixedly arranged on the outer frame; and after the die-cutting piece coarse product passes through the contour waste discharge unit, contour waste is discharged, a primary material belt is formed, hole waste is discharged after the primary material belt passes through the hole waste discharging unit, and a finished die-cutting piece obtained after waste discharging is completed is formed on the material receiving unit. Compared with the prior art, the waste discharge system for the die-cutting piece coarse product with the holes provided by the invention has the advantages of being high in stock of finished die-cutting pieces, short in parking material taking period, efficient in waste discharge, easy to control, free of manual operation, high in yield of the finished die-cutting pieces and the like.

Description

technical field [0001] The invention relates to the field of waste discharge of die-cut parts, in particular to a waste discharge system for rough products of die-cut parts with holes. Background technique [0002] Some die-cut parts will have an inner frame or circle after die-cutting, such as Figure 6 , Pull-down waste is generally adopted when discharging waste. However, for relatively special materials, such as double-sided adhesive tape with a thickness of 0.1mm or more, the stickiness is particularly fast. Generally, the stickiness will occur after more than 2 minutes after punching, causing the inner frame after punching to stick to the main body of the die-cut part again. Pick it up, it's hard to get rid of it. [0003] And because the material tapes are double-sided release, the stickiness of the double-sided adhesive tape to the base material tape and the waste discharge tape is not much different, and it is difficult to completely discharge the waste through the...

However, for special materials, such as double-sided adhesive tape with a thickness of more than 0.1mm, the stickiness is particularly fast. Generally, stickiness will occur after more than 2 minutes after punching, causing the inner frame after punching to stick to the main body of the die-cut part again. pick up, hard to get rid of

[0003] And because the material tapes are double-sided release, the stickiness of the double-sided adhesive tape to the base material tape and the waste discharge tape is not much different, and it is difficult to completely discharge the waste through the pull-down discharge, such as Figure 7 , because both sides of the double-sided collagen paper are coated with silicone oil, when the sealing tape is pulled down to discharge the round hole waste, the round hole waste will not be taken away by the sealing tape, but will remain on the die-cut product. At this time, it is necessary to use Manually deduct the waste of the round hole, which increases the complexity of production and reduces the efficiency
