By adopting the bubble shake-proof device, bubbles can pass through the insertion plates smoothly, and shake is avoided.
Description
Technical field
The utility model belongs to the technical field of film blowing device, is specifically related to a kind of film bubble anti-shake apparatus of film blowing device.
Background technology
The process of film blowing device production film bubble is as follows: the plastics materials of melting is extruded by annular die, forms the just base of film bubble that diameter is less, and film bubble just base, after inflation, just forms the film bubble finished product that diameter is larger, and film bubble finished product is annular plastic foil.From form, the stage casing of film bubble finished product is approximate cylindrical, and film bubble is the approximate taper shape that is of base just.For film bubble finished product (plastic foil of annular) is collected, annular film bubble must be converted into sheet, can be applied to herringbone clamping plate for this reason, herringbone clamping plate are comprised of two of front and back clamping plate, and two clamping plate are combined to form the V font of handstand.When annular plastic foil moves after herringbone clamping plate, will be crushed and be converted into as sheet by circle.In addition, shown in Fig. 1, if the fabric width of plastic foil is larger, just plastic film bubble 5 need to be converted into four fold, need to be applied to the two blocks of triangle plates in left and right, as shown in Figure 2, the horizontal cross sectional geometry of triangle plate 6 is isosceles triangle to the shape of every block of triangle plate 6 for this reason, and along with highly raising, the base length of side of isoceles triangle tee section diminishes gradually.When plastic foil 5 operations are inserted clamping plate through being equipped with the herringbone clamping plate 2(of left and right triangle plate 6 to be called for short) after, will be converted into four fold, as shown in Figure 3.But when the higher film of production viscosity, because the viscous force between film surface and plate surface is larger, and then easily cause film bubble operation not smooth, make constantly shake up and down of film bubble.
Utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming and film bubble anti-shake apparatus that a kind of film blowing device is provided, and it can make film bubble operate steadily through inserting clamping plate in operation, avoids shake.
Its object can realize by following scheme: the film bubble anti-shake apparatus of this film blowing device comprises annular die, annular die top is provided with herringbone clamping plate, the left and right sides of herringbone clamping plate is respectively equipped with triangle plate, it is characterized in that, near the position, boundary of edge, the herringbone clamping plate left and right sides and triangle plate, be respectively equipped with airduct, airduct is communicated with blower fan, and airduct offers spilehole, and the opening of spilehole is towards triangle plate; In the position near annular die, be provided with displacement transducer; Also be provided with central controller, displacement transducer is connected to central controller by holding wire, and central controller is connected to the control circuit of blower fan by holding wire.
The utlity model has following advantage and effect:
One, film bubble constantly extrude and the process that rises in, although the cylindrical profile position on film bubble top there will not be significant change (can not change in theory), but because film bubble bottom is conical, therefore the outline position of film bubble bottom but can occur changing owing to shaking up and down, the utility model has utilized this feature, in the position near annular die, be provided with displacement transducer, this variation therefore can be constantly detected, and testing result is sent to central controller by holding wire; Central controller can judge according to testing result the degree that film bubble is shaken up and down; When film bubble operation is smooth, jitter amplitude exceedes permissible range up and down, central controller order fan starting, the air stream that blower fan produces blows out by the spilehole of each airduct, and form air cushion between film bubble outer surface and triangle plate, reduce and eliminate film bubble and plate viscous force between the two thus, film bubble is operated steadily.When the degree of shaking up and down when film bubble is different, central controller can also the corresponding adjustment wind speed of order blower fan, to guarantee that film bubble operation keeps best plateau.

Fig. 2 is the three-dimensional shape schematic diagram of triangle plate.
Fig. 3 is the mode schematic diagram that herringbone clamping plate and triangle plate flatten film bubble be converted into four fold.
Fig. 4 is the structural representation of a kind of specific embodiment of the utility model.
Fig. 5 is the air duct structure schematic diagram in Fig. 1.
Fig. 6 is A-A cross-sectional view in Fig. 4.
The specific embodiment
Shown in Fig. 4, Fig. 6, the film bubble anti-shake apparatus of this film blowing device comprises that the film bubble anti-shake apparatus of film blowing device comprises annular die 1, annular die 1 top is provided with herringbone clamping plate 2, the left and right sides of herringbone clamping plate is respectively equipped with triangle plate 6, near the position, boundary of edge, the herringbone clamping plate left and right sides and triangle plate, be respectively equipped with airduct 7, airduct 7 is communicated with blower fan 4, and airduct 7 offers spilehole 71, the opening of spilehole 71 is towards triangle plate 6, as shown in Figure 5, Figure 6; In the position near annular die 1, be provided with displacement transducer 3; Also be provided with central controller, displacement transducer 3 is connected to central controller by holding wire, and central controller is connected to the control circuit of blower fan by holding wire.
The concrete control mode of above-described embodiment and principle are as follows: molten plastic material forms just base 50 of film bubble after being extruded by annular die 1, film bubble just base forms columnar film bubble 5 through inflation, film bubble is upwards operation constantly, through herringbone, insert clamping plate 2 and triangle plate 6, in herringbone, insert under clamping plate 2 and 6 actings in conjunction of triangle plate and be converted into four fold, as shown in Figure 6.When displacement transducer 3 detects that the film bubble degree that just base 50 is shaken up and down exceeds the permissible range of setting, central controller order blower fan 4 starts, the air stream that blower fan produces blows out by the spilehole 72 of each airduct 7, and form air cushion between film bubble 5 outer surfaces and triangle plate 6, reduce and eliminate film bubble 5 and triangle plate 6 viscous force between the two thus, film bubble 5 is operated steadily.In addition, the degree that the blast of blower fan 4 can be shaken according to film bubble 5 adjusts accordingly, and makes to guarantee that film bubble 5 keeps best plateau.
