Angle between dynamic bracket 402, lower bracket 403 is 45 °.The inside of 1 two sides of rack respectively upper sliding support 402 with
Position between lower bracket 403 is fixed with the partition 10 for polybag raw material to be separated to doubling, and two partitions 10 are symmetrical
Distribution, and there are spacing between two partitions 10, which determines that the distance of spacing is smaller, after molding according to actual needs
Square under casing bag width it is bigger.Partition 10 divides for two parts, respectively first partition 1001 and second partition 1002, and first
Partition 1001 is linked together with second partition 1002, and first partition 1001 is located at and unreels one end of cylinder 2 close to raw material, and second
Partition 1002 be plate, first partition 1001 be trapezoidal plate, and the trapezoid buckle of two partitions 10 be in horn-like distribution, first every
Plate 1001 is gradually reduced from the one end connecting with second partition 1002 to the thickness of one end far from second partition 1002, first every
Plate 1001 is equipped with arc fillet close to the side that raw material unreels cylinder 2 at bevel edge inflection point.
Arc fillet inner rotation is connected with the first idler wheel 12, and the thickness and first partition 1001 of the first idler wheel 12 are close to former
The thickness that material unreels the side of cylinder 2 is adapted, the first idler wheel 12 with arc angling is concentric installs, and the diameter of the first idler wheel 12
It is consistent with diameter of a circle where arc angling.
The output end of the driving motor 11 of the utility model passes through driving wheel 13 and upper sliding support 402 and lower slider branch
Frame 403 connects.Two are uniformly distributed on the wheel rim of driving wheel 13 for driving sliding support 402, lower bracket 403
The arcuation convex block 14 slided up and down, upper sliding support 402 are equipped with the upper bogie 405 extended downwardly, and lower bracket 403 is also set
There is the lower bogie 406 extended downwardly, the bottom of upper bogie 405, the bottom of lower bogie 406 are respectively equipped with and driving wheel 13
And the second idler wheel 407 that arcuation convex block 14 cooperates, driving wheel 13 are set at the position between two the second idler wheels 407, wherein
The second idler wheel 407 on upper bogie 405 is located at the lower section of driving wheel 13, and the second idler wheel 407 of lower bogie 406 is located at
The top of driving wheel 13, while guaranteeing the center of circle of the circle center line connecting across driving wheel 13 of two the second idler wheels 407, i.e., two second
Idler wheel 407, driving wheel 13 are located on same vertical plane.
The side that the wheel rim and arc bump 14 of driving wheel 13 are contacted with the second idler wheel 403 is equipped with for rolling with second
The race of 407 cooperation of wheel, the second idler wheel 407 roll in race along the side of the wheel rim of driving wheel 13 and arc bump 14,
The center of circle of driving wheel 13 is located at the midpoint of two 407 lines of the second idler wheel.
The utility model only improves oblique point off mould group 4 and partition 10, and rack 1, raw material unreel cylinder 2, open
Tight roller frame 3, the first guide support 5, lateral point off mould group 6, the second guide support 7, hot pressure blanking punch group 8, receiving vat 9 are all made of
The accessory of traditional square-bottom bag machine, the control system and control element of the utility model also use traditional square-bottom bag machine, example
A liter square-bottom bag machine for the JS-DFR800 type of plastics package machinery factory production is such as built by Rui'an City.
At work, driving motor 11 drives driving wheel 13 for sliding support 402, lower bracket 403 on the utility model
Rotation, driving wheel 13 drive arc bump 14 to rotate together, so that two the second idler wheels 407 are simultaneously along driving wheel 13 and arc
The surface scrolls of shape convex block 14, since arc bump 14 is uniformly distributed, and the prominent driving wheel 13 of arc bump 14, thus upper drive
The second idler wheel 407 in moving frame 405, lower bogie 406 can encounter arc bump 14 simultaneously, arcuately convex in the second idler wheel 407
When block 14 rolls, upper bogie 405 drives downwards upper sliding support 402, and lower bogie 406 drives up lower bracket 403,
So that oblique point off cutting die group 404 stamps oblique perforated line to the upper layer and lower layer of raw material in polybag simultaneously simultaneously.This reality
It ensure that with the novel combination using driving wheel 13 and arc bump 14 to drive upper sliding support 402, lower bracket 403
The consistency of the two athletic performance, to improve the working efficiency of oblique point off cutting die group 404.In addition, it is necessary to, it is noted that
The height of the arc bump 14 of the utility model depends on the second idler wheel 407 two groups of oblique point offs when 13 wheel rim of driving wheel rolls
The oblique point of the distance between cutting die group 404, the height of arc bump 14 and the second idler wheel 407 when 13 wheel rim of driving wheel rolls
The distance of breaking mould group 404 to 10 corresponding side of partition is adapted.
Above-described is only preferred embodiments of the present invention, it is noted that for the ordinary skill of this field
For personnel, without departing from the concept of the present invention, various modifications and improvements can be made, these all belong to
In the protection scope of the utility model.
