Abroad, start just to employ chemical stability good from the sixties in last century, air-tightness is excellent, and can carry out packing infusion solutions by resistant to elevated temperatures PP or PE plastic bottle, improves the package quality of medicine preferably and guarantees the quality the storage life.
In PP infusion bottle process, usually adopt two-step method, i.e. stretch blow molding process, first will make PP infusion bottle embryo between stretch-blow, be then made by bottle blowing machine.
The bottle blowing machine used at present, its stretching bar is solid hopkinson bar, interspaces in advance between stretching bar and bottle sealing block, and gas thus space enters a bottle embryo, and radial drawing bottle embryo is to make it shaping.But because air-flow will be hindered when entering bottle embryo, thus bottle embryo is by lower and Shangdi successively distortion, thus cause bottle shaping after wall unevenness even, its percent defective is also higher.And existing bottle blowing machine is difficult to accurate quick position when pressure bottle pipe, if any some deviations, will affect Forming Quality: sometimes the bottle mouth of pipe is not pressed onto position, bottle pipe can come off, sky is caused to blow phenomenon, occur bottle blowing poor quality, the phenomenon of bottle blowing inefficiency, and the bottle mouth of pipe and blow mold are end contact, after air pressure enters mould, air pressure in mould increases, and easily causes the gas leakage of die orifice local, thus impact blowing quality.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides the energy-conservation stretch blow system based on PP infusion bottle blow moulding machine that a kind of bottle blowing efficiency is high, exhaust noise is low and bottle blowing quality is high.
The purpose of this utility model is achieved through the following technical solutions: a kind of energy-conservation stretch blow system based on PP infusion bottle blow moulding machine, it comprises rack-mounted draft cylinder and sealing cylinder, draft cylinder drives stretching bar to move up and down, stretching bar is through the piston of sealing cylinder, piston following in sealing cylinder connects sealing air blowing joint, gas hole is shaped with in sealing air blowing joint, gas hole is connected with the first gas blow pipe, the bottom of sealing air blowing joint is provided with sealing clamping ring, screw thread is shaped with outside sealing air blowing joint, be threaded the nut of a snap ring, recessed shoulder is outside equipped with in sealing clamping ring bottom, the snap ring of nut matches with the recessed shoulder of sealing clamping ring, the diameter of bore of sealing clamping ring is greater than the external diameter of PP infusion bottle oral area, the bottom surface of sealing clamping ring and the baffle ring of PP infusion bottle embryo contact with each other and seal, described stretching bar inner hollow, venthole is offered in its top pressure side, the link of stretching bar is connected with one second gas blow pipe, a steam vent is also offered in described sealing air blowing joint, in steam vent, exhaust joint is installed, exhaust joint is connected with silencer by an exhaust hose.
Described sealing cylinder comprises cylinder body and upper and lower cylinder cap, piston and inboard wall of cylinder block sliding connection.
Described sealing clamping ring is made up of polyurethane material.
Described exhaust hose is provided with a pressure-relief valve.
The utility model has the following advantages: the diameter of sealing clamping ring of the present utility model is greater than the external diameter of PP infusion bottle oral area, make PP infusion bottle energy quick position, improve the location efficiency of PP infusion bottle, and location there will not be deviation, thus strengthen the sealing effectiveness of the bottom surface of sealing clamping ring and the baffle ring of PP infusion bottle embryo; Stretching bar is hollow structure, and offers venthole in top pressure side, and the air pressure making to act on PP infusion bottle embryo inwall is even, PP infusion bottle embryo uniform wall thickness after the blowing, and yield rate improves significantly; Pressure-relief valve can monitor the pressure in sealing air blowing joint, and when air pressure is excessive, release exhaust opened by pressure-relief valve 1, avoids pressure in sealing air blowing joint excessive and cause occurring between sealing clamping ring and baffle ring gas leak phenomenon, ensure that the blowing quality of PP infusion bottle.
