Description
Technical field
The present invention relates to a kind of folding apparatus, more particularly to a kind of valve-port packaging bag folds the vacuum air-changing valve dress of assembly
Put.
Background technology
Braided packing bag, also known as snakeskin bag, are one kind of plastics, and its raw material is mainly the chemical raw materials such as polyethylene, polypropylene.
Woven bag is to be widely used in packing fertilizer, cement, a kind of of chemical products.
Current China and capital construction industry is just advanced with rapid pace at a tremendous pace all over the world.Various countries
The yield of work, building materials especially cement industry is even more to advance by leaps and bounds.But a large amount of bulk product Self-enclosings that these industries need
Packaging bag（Hereinafter referred to as valve-port packaging bag）Valve port molding procedure, industrialized production can not be realized.Each packaging material manufactory
Family is to employ a large amount of labours to lean on worker's craft folding forming packaging bag valve port.One clever skilled young woman worker is double
Hand does not stop to fold as chicken pecks rice, folds three, 4,000 within daily 8 hours to multipotency.Heavy manual labor and severe work
Cause many workers continuously work more than two weeks as environment, finger can be worn bleeding, and elbow, wrist and articulations digitorum manus will swelling, pains
Bitterly, the health of workpeople is had a strong impact on.And substantial amounts of manual labor also needs to expend more production cost.
For this, applicant has submitted a .2 of Application No. 201610524744 application documents, and it discloses a kind of valve
The folding assembly of the mouth full-automatic Production line equipment of packaging bag, includes mounting bracket, the woven bag clamping being set up on mounting bracket
Detent mechanism, the splitting mechanism at woven bag clamping positioning mechainsm, the valve port base being connected with woven bag clamping positioning mechainsm
Piece fold mechanism and gear lath fold mechanism, woven bag clamping positioning mechainsm, valve port blank fold mechanism and gear lath folding machine
Structure is driven by drive component respectively, is connected between drive component and each mechanism by transmission component.Woven bag clamping is fixed
Position mechanism includes the holding piece that the two panels being set up on mounting bracket is oppositely arranged, and one end of two holding pieces is be hinged drive end,
The other end is openend, has grasping part between two holding pieces, splitting mechanism include be distributed on two holding pieces and with it is outer
The vacuum cups of portion's source of the gas connection；Valve port blank fold mechanism includes can be along the grasping part reciprocally swinging of clamping positioning mechainsm
Valve port blank pleated sheet；Gear lath fold mechanism includes to be set up at holding piece can enter laterally clamping sky along grasping part
Between to woven bag gear lath implement fold gear lath pleated sheet.
In use, the be hinged drive end of two holding pieces is driven, and promotes two holding piece opening and closing, in splitting mechanism
Vacuum cups can then implement adhesive to the woven bag in grasping part, and as the opening of two holding pieces implements woven bag
Splitting, after completing splitting, valve port blank pleated sheet is driven to be rocked in grasping part to be implemented to fold to valve port blank, simultaneously
Gear lath pleated sheet is entered in grasping part by the both lateral sides of two holding pieces to be implemented to fold to the gear lath of woven bag.At this
In technical scheme, vacuum cups is that the form that air compressor machine is connected to by cylinder is set, and is realized by the reciprocating motion of cylinder
Suction nozzle produces negative pressure, and such structure is due to the dependence for air compressor machine, and the stability of air pressure can not be met, while gas
Cylinder needs the carry out reciprocating movement of high frequency at work, and air consumption is larger, and it is easy to wear to also result in cylinder, is unfavorable for folding assembly
Long-term stable operation, and the motion control of cylinder need to rely on sensor and circuit part, and structure is complex, into
This is higher.
The content of the invention
It is an object of the invention to provide the vacuum air-changing valve gear that a kind of valve-port packaging bag folds assembly, the device can have
Effect solves conversion and control of the vacuum pressure between break-make and exhaust pressure relief, simple in construction, and converting automation degree is high, work
Process quick and stable and energy-conservation.
Technical solution of the present invention is as follows：A kind of valve-port packaging bag folds the vacuum air-changing valve gear of assembly, it is characterised in that：
Include a piston cylinder, the piston in piston cylinder, the connecting rod for being connected to piston, movable row of the described piston cylinder in piston
Blow vent that the vacuum cups for being communicated on two holding pieces is disposed with journey, the bleeding point for being connected to vavuum pump and
For realizing that the exhaust outlet of pressure release is exhausted in vacuum cups, in addition to drive in connecting rod make piston by blow vent and bleeding point it
Between position to being communicated in reciprocating drive mechanism between the stroke of exhaust outlet.
The present invention is further arranged to, and described connecting rod protrudes from piston cylinder setting, and drive mechanism is included by its rotation
Drive in connecting rod makes piston by moving to the disc cam of exhaust outlet between blow vent and bleeding point, driving piston is reversely returned
The compression spring of position.
The present invention is further arranged to, and described drive mechanism includes rotatable rotary shaft, and described disc cam is set
It is placed in rotary shaft and both synchronous axial systems is set, in the stroke stage that the completions one of two described holding pieces is opened and closed, turns

Pipe is connected to vacuum cups corresponding to two holding pieces.
The present invention has the advantages that：
1st, rotated by the setting of drive mechanism, rotary shaft band moving cam, when two holding pieces are completed to close action and carry out
During opening, the first surface drive link of cam moves downward, and now piston is from the position between blow vent and bleeding point to even
The direction motion of exhaust outlet is passed through, blow vent is communicated in bleeding point when piston passes through bleeding point, blow vent produces negative pressure, very
Suction head can realize the absorption to packaging bag, and as the opening of two holding pieces realizes that woven bag implements splitting, piston continues past
Lower motion, until being communicated in exhaust outlet, the pressure release of vacuum cups is realized, vacuum cups separates with packaging bag, completes since then once
Splitting once is implemented to packaging bag, now cam is rotated further, and the second curved surface of cam offsets with being connected the mover of push rod, spring
Meeting drive link and cam move upwards, are ready for splitting next time.
2nd, the opening of two holding pieces of the invention and the motion closed with cam are consistent, without passing through other knots such as sensor
Structure controls the motion opportunity of piston, with the rotation of rotary shaft, what this gas exchange valve arrangement can open and close in two holding pieces
Process realizes synchronous matching, can have more preferable structural stability, and the mechanism efficiently solves vacuum pressure in break-make and row
Conversion and control between gas pressure release, converting automation degree is high, transfer process quick and stable and energy-conservation.
3rd, the present invention only needs to connect a vavuum pump, is intended merely to provide a negative pressure of vacuum, and adopts in the prior art
Air compressor machine energy consumption is higher, and the present invention more saves, can save it is more use gas, due to this equipment with gas have compared with
High frequency, and the unstable situation of air pressure often occurs in air compressor machine, cause vacuum cups can not normal table work,
And then make jet and the process generation time error of exhaust, it is unfavorable for high-efficiency continuous splitting, and the present invention is more stable.
