Description
Technical field
The present invention relates to a kind of cutting membrane knifes and its expansion structure being exclusively used in frivolous plastic foil.
Background technology
The process of Polywoven Bag production, which generally requires, beats powder-melting-press mold-by plastic grain successively and cuts film-braiding-envelope
The various processes of mouth.The plastics film toughness wherein obtained after press mold is little, not only light but also thin, fixed after being moved by various roller straps to cut
Hymenotome is cut into filament for subsequent braiding.Existing cutting membrane knife is as shown in Figure 1, multiple knifes edge 100 are arranged in juxtaposition, according to follow-up
Braiding need select the cutting membrane knife of different knife edge spacing.Existing cutting membrane knife has multiple technological deficiencies：1, each knife edge is arranged side by side
Setting, the filament being cut out are easy to tangle；2, knife edge spacing is fixed, and the filament of production different in width will replace whole group and cut every time
Hymenotome；3, become the cut point of filament in plastic foil, the adjacent knife edge can apply filament the opposite horizontal force of both direction
Power makes filament raise up, and cutting circuit more long projection amplitude is bigger, and the filament width of back segment is caused obviously to be greater than leading portion,
Yield rate is unstable.
Invention content
In order to solve the above-mentioned problems of the prior art, present invention aims at a kind of filaments cut out of offer to entangle
It twines and keeps each section of wide cutting membrane knife and its expansion structure.
A kind of cutting membrane knife of the present invention, including：Feedboard, feedboard are equipped with the first connector, charging in feed side
The other side of the plate far from feed side each extends over out the first inclined plate and the second inclined plate, and first inclined plate and the second inclined plate are horizontal
Angle is unequal；The feedboard upper surface is extended blade in the first inclined plate and the second inclined plate intersection to feed side,
The blade forms non-zero included angle with feedboard, and blade is towards feed side；First inclined plate and the second inclined plate is separate
The side of feedboard is separately connected a reclaiming plate, and side of the reclaiming plate far from the first inclined plate or the second inclined plate is exit side,
It is equipped with the second connector in exit side；First connector and the second connector shape is adapted and the ruler of the first connector
Very little is twice of the second connector.
A kind of cutting membrane knife of the present invention, the advantage is that, the first connector and the second connector shape be adapted and
The size of first connector is twice of the second connector, therefore can shape is identical and size difference 1/2 cutting membrane knife two
Two combinations, form along the first inclined plate or the multiple cutter of the second inclined plate extending direction infinite expanding.It disposably solves existing
Multiple technologies defect in technology, plastic foil are clearly separated two after blade cut each along the first inclined plate and the second inclined plate every time
Road, by repeatedly continuously to hemisect after, can obtain the plastic filament of enough refinements in least significant end.And every section of filament by
In the guiding role of each cutting membrane knife the first inclined plate and the second inclined plate, is independently separated, will not be tangled completely.Simultaneously because with can
The structure design of autgmentability, can be with multistage-combination, according to the series that the size selection of filament finished product combines, without dismantling whole
Cutting membrane knife.The blade of all cutting membrane knifes is to be longitudinally extended distribution, is all only had at one to the point of plastic foil cutting every time, will not
Generating both direction opposite squeezing action and either segment plastic filament to either segment plastic foil or plastic filament will not be upward
Protrusion ensures that the width of every section of filament is impartial.
Preferably, the blade is vertical with feedboard.Being vertically arranged can make blade more glibly to the plastic foil of feeding
It is cut.
Preferably, first inclined plate, the second inclined plate form the opposite angle of angle equal direction with feedboard respectively.
Both sides angle symmetrical can facilitate subsequent extension extension design, spare part storage to can be minimized design.
Preferably, first inclined plate forms 30 °~45 ° angles with feedboard；Second inclined plate and feedboard
Form -30 °~-45 ° angles.In the angular range, the guidance quality and conveying fluency of material are optimal range, wherein
Optimal angle is 40 °.
Preferably, the reclaiming plate is parallel with feedboard and is not at same plane.Reclaiming plate is parallel with feedboard to be set
Symmetry can be remained by subsequent multistage-combination shape by setting, and reduce the difficulty of extension.
Preferably, first connector is slot of the opening far from blade, and the slot extends along feedboard plane
And it is vertical with blade；Second connector be bolt, the bolt along reclaiming plate plane extend and it is parallel with slot；Institute
The bolt outer diameter stated is the 1/2 of the slot internal diameter, and 1/2 that plug pin lengths are slot length.Specifically disclose one kind first
The connection type of connector and the second connector.
Preferably, the slot open lower end freely extends the supporting parts parallel with feedboard outward.Due to this hair
The bright cutting membrane knife has longitudinal multi-tier, therefore supporting parts are arranged can be by the connection of the cutting membrane knife of two-stage neighboring more
Add firm, the supporting parts of any cutting membrane knife are used for the support when first connector is connected with the second connector of upper level cutting membrane knife
The reclaiming plate of upper level cutting membrane knife enables two-stage cutting membrane knife to keep relatively fixed position.
Preferably, the supporting parts are supporting plate.A kind of structure of supporting parts, under present inventive concept, institute are specifically disclosed
