Description
Technical field
The utility model relates to a kind of plastic bottle blowing machinery equipment, specifically is a kind of drawing mechanism of bottle stretch blowing machine.
Background technology
Plastic hollow vessel such as Coke bottle, mineral water bottle adopts injection moulding to make bottle base; The flow process of the whole piece active line of bottle blowing machine is earlier bottle base to be transferred on the bottle base installation end of bottle base seat; Then bottle base is heated or preheating; Stretch and bottle blowing, the bottle with moulding unloads from bottle blowing machine at last again.Wherein stretching and bottle blowing are accurate adaptive each other processes, and with respect to stretching, gases at high pressure all can influence product quality after getting into bottle base late or too early.Simultaneously, in order to raise the efficiency, often have a plurality of blowing to draw station on the secondary mould, each station is made up of a die cavity and a stretch.In the prior art, the stretch on each station all is connected on the stretching cylinder.Be equipped with on the stretch and seal cylinder, there is sealing device head in the place ahead of sealing cylinder, offers inflatable mouth on the sealing device head, and sealing device head is connected with the said piston that seals cylinder.The piston promotion sealing device head of sealing after the matched moulds in the cylinder is sealed the bottle base mouth, stretches the bottle base that has heated by the stretching masthead that the stretching cylinder promotes, and makes the bottle base elongation.When stretch on the continuous top of stretch, be located at the inflatable mouth air inlet on the sealing device head, get in the bottle base and carry out blowing work.
Because several stretch are connected on the same stretching cylinder; Add the effect length that receives the plastic bottle of producing; So the cylinder length that is equipped with is all long, cylinder diameter is bigger, again with the stopping means limited length; On the books in Chinese patent numbers 200610053667.3, specifically no longer detail.Receive the structural limitations of cylinder own in process of production, and operating characteristic, the movement velocity of cylinder when work is inhomogeneous in fact; Sometimes fast and sometimes slow; Or even the promotion stretch of vibration, cause the product surface of producing that chatter mark is arranged, bottle drawbacks such as wall thickness is inhomogeneous.Even in the bigger bottle embryo of some degree of depth stretches; The stroke of cylinder is bigger, and desired compression gas is also more, and well-known compression of air property is bigger; So the movement velocity of cylinder will be more inhomogeneous; Moreover needed stretching time also can be longer, not only influences the quality of product, also affects production efficiency.
The utility model content
In order to overcome the deficiency of prior art, it is a kind of simple in structure that the utility model provides, and draw speed is fast, and draw speed is even, the drawing mechanism of the bottle blowing machine that the power source stroke is short.
The purpose of the utility model is achieved in that a kind of drawing mechanism of bottle blowing machine; Comprise and seal the cylinder installing plate; Be installed on this installing plate several and seal cylinder, seal cylinder installing plate below and be connected with base plate, base plate and seal and be provided with the portable plate that can on guide pillar, be free to slide between the cylinder installing plate through guide pillar; Stretch is interspersed in to seal in the cylinder and is connected with portable plate, the hinged scissors linkage that is promoted by power source between described portable plate and the base plate.
Described scissors linkage is movably hinged by two pivoted arm central points and constitutes " X " shape, and it is hinged that connecting rod and base plate and portable plate are passed through in the pivoted arm two ends.
Described power source is a cylinder, and cylinder push-rod is connected on the central point of linkage.
Described power source is a hydraulic cylinder.
Described power source is a servomotor, and the driven by motor ball screw is spirally connected with the ball silk braid that is connected on the scissors linkage central point.
Described scissors linkage can be set to the multilayer series connection.
The scissors linkage of said multilayer series connection, its every layer linkage are equipped with independently, and power source promotes.
The beneficial effect of the utility model is: have simple in structurely, draw speed is fast, and draw speed is even, and the power source stroke is short, and production efficiency is high, advantages such as good product quality.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to explain.As shown in the figure: a kind of drawing mechanism of bottle blowing machine; Comprise and seal cylinder installing plate 1; Be installed on this installing plate several and seal cylinder 11, seal cylinder installing plate 1 below and be connected with base plate 4, base plate 4 and seal 1 of cylinder installing plate and be provided with the portable plate 2 that can on guide pillar 3, be free to slide through guide pillar 3; Stretch 12 is interspersed in to seal in the cylinder 11 and is connected with portable plate 2, the hinged scissors linkage 8 that is promoted by power source between described portable plate 2 and the base plate 4.
Described scissors linkage 8 is movably hinged by two pivoted arms, 5 central points 51 and constitutes " X " shape, and pivoted arm 5 two ends are hinged with base plate 4 and portable plate 2 through connecting rod 52.
Described power source is a cylinder 6, and cylinder push-rod 61 is connected on the central point 51 of linkage.
Described power source is a hydraulic cylinder.
Described power source is a servomotor 7, and driven by motor ball screw 71 is spirally connected with the ball silk braid 72 that is connected on scissors linkage 8 central points 51.
Described scissors linkage 8 can be set to the multilayer series connection.
The scissors linkage 8 of said multilayer series connection, its every layer linkage are equipped with independently, and power source promotes (not shown).
Operation principle: in this case, utilize power source to promote scissors hinge arrangement 8 and promote stretch 12 oriented bottle embryos indirectly, so the stroke of stretch 12 motions is the twice of power source stroke that speed also is the twice of power source speed.Also can be set to the multilayer series connection by linkage, to obtain movement velocity faster.Therefore this case in, the stroke of power source can be arranged to the half the of common bottle blowing machine, or even littler.Because reduced the stroke of cylinder, can effectively avoid cylinder when big stroke motion, need charge into a large amount of compressed air in the cylinder; A large amount of easy build-ups of pressure of gas is unstable; Cause movement velocity inhomogeneous, cause stretched product to be undaform, bottle drawbacks such as wall thickness is inhomogeneous.The motion of the big stroke of cylinder simultaneously also needs long stretching time, needs more compressed air, thus this case also to have a draw speed fast, high efficiency, advantage such as consumes energy is few.
In addition, in this case, can also use servomotor or common reducing motor, drive ball screw 71, be spirally connected with the ball silk braid 72 that is connected on scissors linkage 8 central points 51.The revolving force dress of servomotor is changed to the straight-line thrust of promotion linkage.Because servomotor moment is stable, so its speed that promotes stretch 12 will be more uniform and stable.But can utilize the control type of servomotor simultaneously, the movement travel of STOCHASTIC CONTROL stretch 12 is so that produce the product of different length.
