Description
Technical field
The invention belongs to woven bag technical field, specifically a kind of food packaging BOPP film Polywoven Bag.
Background technique
Polywoven Bag is configured to Polypropylene Bag, Polythene Bag by main material；It is divided into seam bottom bag, tape edge by method of sewing
Bottom bag；It is now widely used for a kind of packaging material of fertilizer, chemical products and other items；Its main production is to utilize plastics
Raw material is flat filament through extrusion film, cutting, simple tension, by obtaining product, commonly referred to as woven bag through knitting device.
BOPP film, that is, bidirectional stretching polypropylene film, its production be the melt of macromolecule polypropylene is passed through first it is long and narrow
Sheet material or thick film is made in head, then in dedicated stretching-machine, at certain temperature and the speed of setting, while or substep
The stretching carried out in vertical both direction (longitudinally, laterally), and by cooling appropriate or heat treatment or special processing
Film made of (such as corona, coating etc.).
Common BOPP film include: plain edition bidirectional stretching polypropylene film, heat sealing type biaxial-tension polypropylene film,
Cigarette packaging film, Biaxially oriented polypropylene pearl film, Biaxially oriented polypropylene metalized film, matt film, multiple book film, laser molding
Film, anti false film and paper ball film etc..
BOPP film Polywoven Bag is commonly used to the particle foods such as dress rice in routine use, weaves after rice is taken
Bag inner height reduces, it is necessary to go deep into woven bag taking, be unfavorable for fast and easy and take.
Summary of the invention
In order to make up for the deficiencies of the prior art, solving woven bag inner height after rice is taken reduces, it is necessary to deeply braiding
The problem of being taken in bag, being not easy to operation, a kind of food packaging BOPP film Polywoven Bag proposed by the present invention.
The technical solution adopted by the present invention to solve the technical problems is: a kind of food packaging BOPP of the present invention

Portion is equipped with lifting unit, and lifting unit is used to support spring and rises or falls；It is upward by the spiral cloth bag spiral above pedestal
It is wound on the outside of support spring, tubular structure is formed, for holding rice；Support spring plays skeleton function, for keeping spiral
Cloth bag tubular construction；Between spiral cloth bag and support spring be equipped with clamping unit, clamping unit both ends respectively with spiral cloth bag and
Support spring is affixed, and clamping unit facilitates spiral cloth bag Fast Installation and disassembly, after the rice height in woven bag declines, benefit
Woven bag bottom is tightened with bill kept on file member is received, lifting unit reduces support spring height, opens spiral cloth bag top and support bullet
The clamping unit of spring, exposes more rice, takes rice easily and fast.
Preferably, the clamping unit includes fixture block, card slot, rotating bar and support component；Fixture block is equipped in the card slot,
It is clamped in fixture block insertion card slot；The card slot is equipped with a pair of of rotating bar close to the positional symmetry of opening, and rotating bar is hinged with card slot,
Torsional spring is equipped between rotating bar and card slot；Support component is equipped on the inside of the card slot；By fixture block front end protrusion slowly close to card
Slot, fixture block front end protrusion open rotating bar, and fixture block continues into card slot to being scheduled in support component, and fixture block front end protrusion is got at this time
Rotating bar is crossed, rotating bar sets back under the action of torsional spring, clamping fixture block front end protrusion, so that spiral cloth bag and support spring
Close connection, is not easy to loosen, and it is unrestrained to avoid rice.
Preferably, the rotating bar is equipped with locking assembly close to the side that card slot is open；The locking assembly includes flexible
Piece, telescopic hole, constrictor and compression chamber；Compression chamber is offered in the rotating bar, compression cavity inner sleeve has constrictor；The card slot
It is inside symmetrically provided with a pair of of telescopic hole, is cased with stretchable sheet in telescopic hole；The compression chamber is connected to telescopic hole by pipeline；Pass through pressure
Contracting bar is freely slidable in compression chamber, between constrictor and compression chamber be equipped with reset spring, reset spring both ends respectively with pressure
Contracting bar and compression chamber are affixed, the telescopic hole be it is arc-shaped, stretchable sheet, stretchable sheet and telescopic hole correspondingly-shaped are equipped in telescopic hole
Cooperation, when the fixture block is connect with card slot, fixture block opens constrictor, and constrictor squeezes compression chamber and generates compressed air, and compression is empty
Gas is entered in telescopic hole by pipeline, and compressed air pushes stretchable sheet to stretch out, stretchable sheet clamping fixture block, so that fixture block blocks in insertion
The component that is locked after slot locking.
