Description
Technical field
This utility model relates to the parts of a kind of Bag Making Machine, the back cover cutter of the most explosion-proof angle plastic bag.
Background technology
The waistcoat type plastic bag commonly used on market, broken line 10 in folding 15(within bag 9 dual-side adds, with reference to figure
15), to reduce the width of plastic bag, it is to avoid reel is wide.The raw material used is the above-mentioned thin mould of tubular plastics being folded into lamellar,
Bag Making Machine is cut length L into needing, the two ends up and down of each section (length L of a plastic bag) of segmentation is adopted simultaneously
Binding cutter 19 and back cover cutter 1 seals with corresponding on hot knife, i.e. bind line 11, back cover line 13, between the two with cutting knife 18 edge
Cut line 17 and cut (refer to Figure 14 and Fig. 5)；In subsequent handling, the top of each bag 9 tangentially 12 is cut out U-shaped
Groove, forms the bag ear 16 of plastic bag), owing to the hot-sealing line (back cover line 13) of common plastics bag is straight line, back cover line 13
Interlude be the heat-sealings of two layers of plastic foil, and both sides Duan Ze is due to the reason of bag two endopleurite, is to be moulded by four layers or more layers
Charge level heat-sealing forms, at interlude and section junction, both sides (broken line 10 and the intersection point of back cover line 13 in i.e.), because being in different thickness
Degree joins and has the relation of dog-ear, in use, is the most often in least favorable stress, when plastic bag is in inflation
After, or containing article when making intrinsic pressure reaching to a certain degree, back cover line 13 easily bursts herein, produces slight crack, causes and ruptures (custom
Claim quick-fried angle).In order to overcome this shortcoming, people is had to change hot-sealing line into sweep at the interlude of bag 1 with section junction, both sides
14(such as curved line), can substantially reduce the probability at quick-fried angle.The hot-sealing line of bending needs hot knife (back cover cutter--the heat of bending
The hot knife of envelope plastic bag bottom), the plastic bag of each specification (width) needs corresponding hot knife, often produces a kind of new spec
Plastic bag will change correspondence hot knife, bother very much, reduce production efficiency.
Summary of the invention
This utility model aims to provide the back cover cutter of a kind of explosion-proof angle plastic bag, to solve the often production that prior art exists
The plastic bag of a kind of new spec will change the hot knife of correspondence, bother very much, the problem reducing production efficiency.
The technical solution of the utility model is: the back cover cutter of a kind of explosion-proof angle plastic bag, including basic cutter hub, in its one side
It is provided with rectilinear edge, it is characterised in that at two ends, be respectively equipped with in the side being provided with blade of described basic cutter hub
One groove and the second groove, at least install a curved block in this first groove, and the side of this curved block sets near end
There is bending blade, be respectively arranged at the two ends with the rectilinear edge section corresponding with described rectilinear edge at this bending blade；This second
At least being provided with a straight envelope block and another described curved block in groove, this side directly sealing block is provided with and described straight line cutter
The corresponding identical straight line sword of sword, this straight line sword is corresponding with the rectilinear edge section of adjacent curved block one end；Described curved block
It is connected with the screw being located at the first groove and the second bottom portion of groove by screw with the corner of straight envelope block.
Described curved block includes left curved block and right curved block, the bending blade deflection left end of this left curved block, this right side
The bending blade deflection right-hand member of curved block.
In described curved block bending blade be shaped as arc or the curve of round and smooth continuous bend.
The utility model has the advantages that: can be combined into by changing different curved block can give birth to the straight position sealing block
Produce the hot knife of plurality of specifications plastic bag, it is not necessary to change whole hot knife, substantially increase production efficiency, reduce and produce into
This.

Detailed description of the invention
Seeing Fig. 1～Figure 13, the back cover cutter of a kind of explosion-proof angle of this utility model plastic bag, including basic cutter hub 1, at one
Face is provided with rectilinear edge 4, is respectively equipped with the first groove at the close two ends of the side being provided with blade of described basic cutter hub 1
7 and second groove 8, in this first groove 7, curved block 2 is installed, the side of this curved block 2 is provided with bending cutter near end
Sword 21, is respectively arranged at the two ends with the rectilinear edge section 23 corresponding with described rectilinear edge 4 at this bending blade 21.Second recessed at this
Being provided with length is equal and is mutually butted directly envelope block 3 and another curved block 2 in groove 8, this side directly sealing block 3 is provided with and institute
The corresponding identical straight line sword 31 of the rectilinear edge 4 stated, rectilinear edge section 23 phase of this straight line sword 31 and adjacent curved block 2 one end
Corresponding.The corner of described curved block 2 and straight envelope block 3 is provided with this through hole of through hole 22(and can set counterbore, makes the nut of screw 5 sink
Enter), connect through a screw 5 with being located at screw 6 corresponding bottom the first groove 7 and the second groove 8 in each through hole 22.Directly
In the bottom of envelope block 3 and curved block 2 coordinates embedding the first groove 7 and the second groove 8.
The length of the first groove 7 of the present utility model and the second groove 8 also can extend, and accommodates plural straight envelope block 3
Or curved block 2, to increase different compound modes, it is possible to produce the plastic bag of more specification (width).
Described curved block 2 includes left curved block and right curved block, and the bending blade 21 of this left curved block is partial to left end, should
The bending blade 21 of right curved block is partial to right-hand member.Bending blade 21, rectilinear edge 4, rectilinear edge section 23, the cross section of straight line sword 31
Shape identical (conventional is trapezoidal).
In described curved block 2 bending blade 21 be shaped as arc or the curve of round and smooth continuous bend.
This utility model in use, conventionally by basic cutter hub 1 with bind cutter 19 and cutting knife 18 is assembled in one
Rising (seeing Figure 14), cutting knife 18 is at basic cutter hub 1 and binds between cutter 19, and basic cutter hub 1 and the cutter 19 that binds are provided with electric heating
Device.By installing left curved block (shown in Fig. 8) or right curved block (shown in Fig. 9) in monolithic groove 7, and at double block groove
8 exchange curved block 2 and the straight positions sealing block 3, or install left curved block or right curved block at the same position of double block groove 8,
(i.e. two bending hot-sealing lines 14 of bottom hot-sealing line 13 in Figure 15 can be produced in the way of multiple different in width plastic bag being combined into
Spacing have multiple), Figure 10-Figure 13 merely illustrates four kinds of compound modes.
