Description

Paper angle bead trompil mould

Technical Field

The utility model relates to a paper angle bead production facility technical field relates to a paper angle bead trompil mould.

Background

The paper corner protector is also called an edge plate, is one of the most popular international packaging products, is used for replacing wood packaging and other heavy packaging modes, and has the characteristics of low price, light weight, firmness, environmental protection requirement compliance and the like.

In order to bind the paper corner protectors conveniently, when the paper corner protectors wrap the goods, the paper corner protectors are usually bound tightly by the binding belts, and the binding belts are bound on the side faces of the goods in the annular direction and are easy to move relative to the paper corner protectors, so that the binding effect is influenced. After the holes are punched on the paper corner protectors, the binding bands are arranged along the circumferential direction of the punched holes on the paper corner protectors, so that the positions of the binding bands are limited, and relative movement between the binding bands and the paper corner protectors is avoided.

The existing punching die for the paper angle bead utilizes the mutual matching connection of the upper die and the lower die to realize punching of the paper angle bead, and because the two ends of the paper angle bead are not clamped during actual punching, the processing stability of the paper angle bead is reduced, thereby influencing the punching effect of the paper angle bead.

SUMMERY OF THE UTILITY MODEL

The utility model aims at having the above-mentioned problem to current technique, provided a paper angle bead trompil mould, be convenient for press from both sides tight paper angle bead before punching to improve the processing stability of paper angle bead.

The utility model provides a paper angle bead trompil mould, includes cope match-plate pattern, lower bolster and locates the guide assembly between cope match-plate pattern and the lower bolster, the lower bolster on be equipped with the locating piece that is used for fixing a position the paper angle bead, the cope match-plate pattern on be equipped with the locating piece just to push down the briquetting that is used for pushing down the paper angle bead that sets up, the middle part of briquetting has vertical extension's through-hole, the through-hole in wear to be equipped with the punching press head that the cope match-plate pattern was worn to be equipped with the upper end, the length of punching press head is greater than the maximum distance of cope match-plate pattern upper surface to briquetting lower surface, punching press head and cope match-plate pattern and/or briquetting between be equipped with the elastic drive subassembly that makes the briquetting contact the paper angle bead earlier when being equipped with the compound die, the. The elastic driving assembly can be arranged between the stamping head and the upper die plate, and can also be arranged between the stamping head and the pressing block.
