Abstract
A sealing device of the valve bag. The sealing device of the valve bag is exquisite in structure, low in manufacturing cost and stable in working state, and can effectively prevent materials from flowing out of the packaging bag and the packaging nozzle after being used, so that the pollution to the working environment and the waste of the materials are effectively avoided. Establish on the packing mouth, the annular groove has been seted up on the outer wall of packing mouth, the closing device is including sealing the ring, seal the ring and be cyclic annular, and make by elastic material, the both sides outer fringe of sealing the ring supports respectively on the both sides lateral wall of annular groove. The sealing device further comprises an air faucet and an air pump, the air faucet is fixedly connected to the sealing ring, and the air pump is detachably connected to the air faucet. One side of the side walls of the two sides of the annular groove, which is close to the groove bottom, is provided with an annular recess which is recessed towards the side far away from the center of the annular groove. The device has the advantages of exquisite structure, low manufacturing cost and stable working state on the whole.
Description
Technical field
Powder packaging, filling apparatus field are the utility model is related to, more particularly to wherein packs the improvement of mouth.
Background technology
As shown in Figure 1, nowadays when being packed to powder, usually first packaging bag is socketed on packaging mouth, is then turned on
Packing machine, powder is sent into packaging bag.However, people have found when in use, by effects of air pressure, powder is being sent into packaging bag
During often there is problems with：First, packaging bag can not fill up, bubble packs the powder in back pkt. excessively, every time in packaging bag
Measure it is inconsistent, so as to bring strong influence to conevying efficiency, value accounting；2nd, powder easily wraps certainly in packaging process
Gap between pack and packaging mouth outwards leaks out, so as to seriously polluted the air quality of packing shop, and gives production cost
Bring great increase.
In this regard, State Bureau disclosed on January 2nd, 2002, a entitled " a kind of powder material package machine is filled from exhaust
Fill mouth ", the Chinese utility model patent of Application No. " 01203496.7 ", in the case will packaging mouth be arranged to it is two layers inside and outside, from
And exhaust interlayer is formed, and an exhaust pipe is connected in interlayer is vented, so as to carry out air pressure balance in packaging process.Such skill
The side that the art scheme fixture that generally use pushes during the work time is socketed in valve bag in packaging mouth is clamped sealing, so
And since the mouth size of valve bag is typically larger than the outside diameter of packaging mouth, will be because of the sack of valve bag even if employing fixture
It is folded fold and there are minim gap, even if in this way, leak without material material-filling initial stage, but with pressure in valve bag
Change, still will appear from the problem of material leaks, flies upward.
The content of the invention
The utility model in view of the above problems, propose a kind of delicate structure, cost is low and stable working state for manufacture, make
It can effectively avoid material after to flow out between mouth from packaging bag and packing, so as to effectively avoid pollution and the material of working environment
Waste valve bag closing device.
The technical solution of the utility model is：It is located on packaging mouth, annular groove is offered on the outer wall of the packaging mouth,
The closing device includes seal mouth ring, and the seal mouth ring is annular in shape and is made of elastic material, the both sides outer rim of the seal mouth ring
It is against respectively on the both sides side wall of annular groove.
The closing device further includes gas nozzle and air pump, and the gas nozzle is fixedly connected on seal mouth ring, and the air pump is removable
That unloads is connected on gas nozzle.
The cross section of the seal mouth ring is arc-shaped, and the central angle of the arc is 1-180 °.
The both sides side wall of the annular groove is offered close to the side of slot bottom is directed away from annular groove center place one
The concave ring-shaped depression in side.
When the utility model is used, after valve bag puts on packaging mouth, seal mouth ring inside can be inflated, so that
Seal mouth ring outwards struts the sack for propping up valve bag, in this way, again after subsequently fixture is loaded onto, you can so that the sack of valve bag exists
By stable clamping in the case of keeping smooth, and then it effectively prevent the sack of valve bag there are small because of the presence of fold
The problem of gap, further prevented occur the possibility that material leaks, flies upward during material-filling.There is structure essence on the whole
Ingeniously, the advantages of manufacturing low cost and stable working state.
Brief description of the drawings
Fig. 1 is the structure diagram of this case,
Fig. 2 be the use state of this case with reference to figure one,
Fig. 3 is the use state of this case with reference to figure two；
1 is packaging mouth in figure, and 10 be annular groove, and 100 be ring-shaped depression, and 2 be seal mouth ring, and 3 be valve bag.
Embodiment
The utility model as shown in Figs. 1-3, is located on packaging mouth 1, and annular groove is offered on the outer wall of the packaging mouth 1
10, the closing device includes seal mouth ring 2, and the seal mouth ring 2 is annular in shape and is made of elastic material, the two of the seal mouth ring 2
Side outer rim is against on the both sides side wall of annular groove 10 respectively.After valve bag puts on packaging mouth, seal mouth ring inside can be carried out
Inflation, so that seal mouth ring outwards struts the sack for propping up valve bag, in this way, again after subsequently fixture is loaded onto, you can so that
The sack of valve bag, by stable clamping, and then effectively prevent the sack of valve bag because of fold in the case where keeping smooth
The problem of in the presence of and there are minim gap, further prevented occur the possibility that material leaks, flies upward during material-filling.
In addition, also just due to that can keep lasting close between seal mouth ring may be such that the sack of valve bag and pack mouth outer wall
Envelope, therefore, may be such that the effect of exhaust pipe is more stable during material-filling, that is, cause material it is filling it is more smoothly,
And it is filling after it is more convenient to vacuumizing for valve bag.
The closing device further includes gas nozzle and air pump, and the gas nozzle is fixedly connected on seal mouth ring, and the air pump is removable
That unloads is connected on gas nozzle.So as to be inflated after air pump is opened via gas nozzle between seal mouth ring and annular groove, envelope is realized
The outside distracted action of choma.
The cross section of the seal mouth ring 2 is arc-shaped, and the central angle of the arc is 1-180 °.
The both sides side wall of the annular groove 10 is offered close to the side of slot bottom is directed away from 10 center institute of annular groove
In the concave ring-shaped depression 100 in side.So as to which the ring-shaped depression of the both sides by annular groove more preferable, more stable can block
The both sides outer rim of seal mouth ring, so that seal mouth ring has more preferable structural stability when using, to the close of the sack of valve bag
It is more preferable to seal effect.
