Description
Technical field
The invention belongs to the blowning installation technical field of blow moulding machine, be specifically related to a kind of plastic hollow goods inflation molding and use
Rotation blow needle device.
Background technology
The function of the blow needle of plastic hollow goods inflation forming machine is known, and can be in disclosed Chinese patent literature
In be seen in, as CN102848559B recommends have " ventilation type blow needle mechanism ", CN103144285A to be provided with " blowing of a kind of blow moulding machine
Needle device ", CN204894486U introduce have " a kind of blow moulding machine blow needle lifting regulating mechanism " and CN104527037A announcement have " in
Blow needle device in empty blow moulding machine ", etc..
By to being not limited to the reading of patent documentation exemplified above, the blow needle head of blow needle device is lifting,
Also can see this Instructions Page 3 the 11st of CN104527037A and walk to page 4 the 4th row by emphasis, the lifting of blow needle head is by blowing
Syringe needle drive mechanism drives.Specifically, blow needle head drive mechanism blow needle body is driven, owing to blow needle head is to fix with blow needle body
Connect, thus lifted together with blow needle head by blow needle body, and the up-down mode of blow needle head has following two: one is by as blowing
The action of the cylinder of syringe needle drive mechanism and make blow needle head lift；Two is by the work of the oil motor as blow needle head drive mechanism
Make blow needle head to lift clockwise or counterclockwise.The former is applicable to the inflation molding to small plastic hollow product, the latter
It is applicable to the inflation molding to capacious plastic hollow goods.For use require harsh and volume bigger for fill
The screw thread of the oral area of the plastic hollow vessel of chemical industry or even harmful influence etc is usually female thread, matches the most therewith
Lid just as the convex shape of inverted plug screw shape, and the screw thread covered is certainly for external screw thread.Empty in the plastic
The inwall of oral area forms the self-evident strong point of female thread and is: good airproof performance, screw thread are hardly damaged and safety and sanitation, etc.
Deng.From preceding description, the screw thread on the inwall of the oral area of plastic hollow goods i.e. inner thread is blowing by blow needle device
Blow needle head external screw thread on syringe needle is formed.
The most aforementioned CN204894486U of prior art is owing to have employed oil motor (patent claims " power motor ") as blow needle
Head drive mechanism, owing to the control difficulty of oil motor is big and impulsive force is also big, thus the stationarity of the elevating movement of blow needle head is difficult
To ensure, and the machining accuracy of the parts being associated with oil motor is the harshest, the most fragile.Furthermore, oil
The oil pipe pipeline of motor is many and complicated, in use can occur oil liquid leakage situation every now and then, on the one hand gives the suitable of production
Profit carries out producing impact, adds workload on the other hand to daily managing and protecting.And then, owing to the precision of oil motor is difficult to control to,
Screw thread (aforesaid inner thread) quality thus resulting in the oral area of plastic hollow goods cannot ensure, there will be thread time serious
Rotten tooth or collapse dental phenomenon, cause whole product rejection.
For above-mentioned prior art, the applicant has made lasting exploring and design repeatedly, below will finally define
Technical scheme to be introduced, and under taking secrecy provision, central laboratory the applicant is tested, result
Prove practicable.
