Invention content
The object of the present invention is to provide a kind of burst bar tearing notch mechanism and manufacturing devices and manufacturing method.
Present invention technical solution used for the above purpose is：Burst bar tearing notch mechanism, burst bar are mounted on bag
In body upper side thin membrane, including gib block and mounting portion, the tearing notch mechanism of burst bar end includes lift end and connecting pin, lift end
It is longitudinally cut through by notching mechanism, there is part tie point not cut by cutting the pull-up end margin one formed, when external force pulls post-tensioning
Origin or beginning can be pulled up, and connecting pin is by the longitudinally cutting rear reservation bag body upper side thin membrane of notch features and gib block.
Further, the shape at the edge one is buttferfly-type or c-type.
Further, the tie point is 2-4.
The manufacturing device of above-mentioned burst bar tearing notch mechanism, including notching mechanism, the notching mechanism be divided into upper cut portion and
The lower end of incision oral area, upper cut portion is that cutter one is matched with one shape of pull-up end margin, described cutter a kerf have protrusion and
Recess portion, protrusion forms cut edge one after cutting, and recess portion forms tie point, and the upper end of the incision oral area is cutter two and connect
Hold shape matching.
Further, it is backing plate below incision oral area, the backing plate is SiO2·nH2O backing plates.
Further, the notch of the cutter two is rectangular zigzag, prevents from all cutting through, solves a previous word and cross and cut
The problem of causing bowknot to fall off with burst bar.
The method of above-mentioned manufacturing device manufacture side organ bag body burst bar, bag is mounted on by burst bar gib block and mounting portion
In body upper side thin membrane, then bag body is placed between upper cut portion and incision oral area, all wear pull-up end margin, including are followed successively by
Upper side thin membrane, gib block, mounting portion, organ face and downside film form back-off mechanism behind the film of downside, and connecting pin is only
Retain upper side thin membrane and gib block, mounting portion, organ face and the cut-out of downside film.Formed back-off principle be when upper cut portion to
It is contacted with incision oral area when incision, in incision oral area by under the certain active force in upper cut portion, it will pressure transmission to pad
Plate, because backing plate is relatively soft, compressive deformation lateral deviation, and the back sides knife 1-1 are higher by plane 0.5mm, when the power for giving 0.5Mpa or more
When, knife can integrally form 5 ° of inclination, and upper side thin membrane is inserted into bottom side, be specifically shown in 125, form the back-off of bag body
Beneficial effects of the present invention are：In bag making process, bowknot is more smooth, will not tilt or interfere with other devices,
Cause equipment damage or sack waste product.Bowknot lift end forms the tie point being adhered by blade is rough and uneven in surface, can be used as anti-fake
And anti-theft function, judge whether this position is previously opened by the connection of bowknot dotted line point.Back-off shape is formed on bag body bottom
Formula, organ face are not opened, and also more conducively sucker captures.The notch for connecting Front cutting tool is rectangular zigzag, prevents from all cutting through, solve
A previous word of having determined, which is crossed, cuts the problem of causing bowknot to fall off with burst bar.

Specific implementation mode
Explanation is further explained to the present invention with reference to specific embodiment.
As shown in Figs. 1-3, burst bar tearing notch mechanism, burst bar is mounted in bag body upper side thin membrane 131, including gib block
111 and mounting portion 121, the tearing notch mechanism of burst bar end includes lift end 211 and connecting pin 231, and lift end 211 is by slotting machine
Structure is longitudinally cut through, and is had 3 tie points 2112 not cut by cutting the 211 buttferfly-type edge 1 of lift end formed, is worked as external force
Pullling rear lift end 211 can be pulled up, and connecting pin 231 is by the longitudinally cutting rear reservation bag body upper side thin membrane 131 of notch features and leads
To item 111.
The manufacturing device of above-mentioned burst bar tearing notch mechanism, such as Fig. 4 and Fig. 5, including notching mechanism, the notching mechanism is divided into
The lower end of upper cut portion 1 and incision oral area 2, upper cut portion is that cutter 1 is matched with one 2111 shape of pull-up end margin, described
Cutter a kerf has protrusion 3111 and recess portion 3112, and protrusion forms cut edge one after cutting, and recess portion forms tie point, under described
The upper end of notch is that cutter 2 511 is matched with connecting pin shape.It is backing plate 3 below incision oral area, the backing plate is
SiO2·nH2O backing plates.The notch of the cutter two is rectangular zigzag, prevents from all cutting through, solves a previous word and cross to cut and make
The problem of falling off at bowknot and burst bar,.
The method of above-mentioned manufacturing device manufacture side organ bag body burst bar, bag is mounted on by burst bar gib block and mounting portion
In body upper side thin membrane, then bag body is placed between upper cut portion and incision oral area, all wear pull-up end margin, including are followed successively by
Upper side thin membrane, gib block, mounting portion, organ face and downside film form back-off mechanism behind the film of downside, and connecting pin is only
Retain upper side thin membrane and gib block, mounting portion, organ face and the cut-out of downside film.Formed back-off principle be when upper cut portion to
It is contacted with incision oral area when incision, in incision oral area by under the certain active force in upper cut portion, it will pressure transmission to pad
Plate, because backing plate is relatively soft, compressive deformation lateral deviation, and it is 0.5mm that one back sides 1-1 of cutter, which are higher by level h, when giving
When the power of 0.5Mpa or more, knife can integrally form 5 ° of inclination, and upper side thin membrane is inserted into bottom side, forms bag body back-off structure 125.
The advantages of sack of the present invention makes be：In bag making process, the more smooth such as Fig. 6 and Fig. 8 of bowknot will not be tilted
Or interfere with other devices, cause equipment damage or sack waste product.Bowknot lift end is adhered by rough and uneven in surface formed of blade
Tie point can be used as anti-fake and anti-theft function, judge whether this position is previously opened by the connection of bowknot dotted line point.Bag
Back-off form is formed on body bottom, and organ face is not opened, and also more conducively sucker captures, such as Figure 10 and Figure 11.Connection Front cutting tool is cut
Mouth is rectangular zigzag, prevents from all cutting through, solves the problems, such as that a previous word is crossed to cut and bowknot is caused to fall off with burst bar, such as
Figure 12.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art in the technical scope of present disclosure, according to the technique and scheme of the present invention and its
