Abstract

The utility model relates to a cut-off tool for a zipper fillet. The cut-off tool for the zipper fillet comprises an upper knife and a lower knife and is characterized in that an upper knife edge is arranged on one side of the upper knife, and the upper knife edge is an arc-shaped groove which is arranged in one side of the upper knife in a concave mode. A lower knife edge is arranged on one side of the lower knife, the lower knife edge is an arc-shaped boss which is arranged on one side of the lower knife in a convex mode. The surface of the arc-shaped boss of the lower knife edge is matched with the surface of the arc-shaped groove of the upper knife edge. According to the cut-off tool for the zipper fillet, a linear knife edge of a traditional cut-off tool is changed to be the arc-shaped knife edge, a cut patch fillet is of an arc shape, and the problem that a human body can be scratched easily in the process of subsequent packaging, sewing and the like is solved.

Description

Slide fastener fillet cutting off tool

Technical field

The utility model relates to a kind of Zipper-cutting cutter, especially a kind of slide fastener fillet cutting off tool.

Background technology

At present in the slide fastener industry, to the cut-out of zipper cloth belt, the mode that adopts cutter to cut usually.Existing Zipper-cutting cutter comprises upper slitter 1a and following cutter 4a.As Fig. 6, shown in Figure 7, the side of upper slitter 1a arranges edge of a knife 2a; As Fig. 8, shown in Figure 9, the side of following cutter 4a arranges down edge of a knife 5a, and last edge of a knife 2a and following edge of a knife 5a match and be linear.For slide fastener, adopt the technological deficiency of present traditional cutting off tool to be Zipper-cutting after, patch back the top of the horn sharp (as shown in figure 10) is in subsequent packages, make etc. in the process and scratch workman's health easily.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of slide fastener fillet cutting off tool is provided, solved slide fastener in subsequent packages, the problem that scratches health in the process easily such as make.

According to the technical scheme that the utility model provides, a kind of slide fastener fillet cutting off tool comprises upper slitter and following cutter, and it is characterized in that: a side of described upper slitter arranges the edge of a knife, and the last edge of a knife is the circular groove that is arranged with in upper slitter one side; A described side of cutter down arranges down the edge of a knife, and the following edge of a knife is the arc cam that is convexly equipped with in following cutter one side; Match with the circular groove surface of the last edge of a knife in the arc cam surface of the described edge of a knife down.

Middle part, the lower end of the edge of a knife arranges upper shed on described, in the described upper center of the edge of a knife down under shed is set, to dodge the slide fastener separate pieces.

Slide fastener fillet cutting off tool described in the utility model is the circular arc edge of a knife when linear edge of a knife of traditional cutting off tool is changed, and the patch corner that cuts out is circular arc, thereby has solved in subsequent packages, the problem that scratches health in the process easily such as make.

The specific embodiment

The utility model is described in further detail below in conjunction with concrete accompanying drawing.

As Fig. 1 ~ shown in Figure 4: as described in slide fastener fillet cutting off tool comprise upper slitter 1, go up the edge of a knife 2, upper shed 3, cutter 4, the edge of a knife 5, under shed 6, slide fastener separate pieces 7 etc. down down.

The utility model comprises upper slitter 1 and following cutter 4.As shown in Figure 1 and Figure 2, a side of described upper slitter 1 arranges the edge of a knife 2, and the last edge of a knife 2 is for being arranged with the circular groove in upper slitter 1 one sides; As shown in Figure 3, Figure 4, a described side of cutter 4 down arranges down the edge of a knife 5, and the following edge of a knife 5 is for being convexly equipped with the arc cam in following cutter 4 one sides; Match with the circular groove surface of the last edge of a knife 2 in the arc cam surface of the described edge of a knife 5 down;

As shown in Figure 1, middle part, the lower end of the edge of a knife 2 arranges upper shed 3 on described; As shown in Figure 3, in the described upper center of the edge of a knife 5 down under shed 6 is set.

Operation principle of the present utility model and the course of work: slide fastener separate pieces place 7 place's straps are cut off through the interaction of upper slitter 1 and following cutter 4, because the last edge of a knife 2 is the circular arc that matches with the following edge of a knife 5, so the patch corner after cutting off is circular arc (as shown in Figure 5), the patch corner of having avoided causing because of the linear edge of a knife sharply, easily scratches the problem of health.
