Description
Technical field
The invention belongs to the blowning installation technical field of blow moulding machine, and in particular to a kind of plastic hollow product inflation shaping is used
Rotation blow needle device.
Background technology
The function of the blow needle of plastic hollow product inflation forming machine is known, and can be in disclosed Chinese patent literature
In be seen in, as CN102848559B recommends to have " ventilation type blow needle mechanism ", CN103144285A to be provided with, " a kind of blow moulding machine blows
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 the reading to being not limited to patent document exemplified above, the blow needle head of blow needle device is lifting,
To this can also emphasis referring to the CN104527037A row of Instructions Page 3 the 11st to the 4th row of page 4, the lifting of blow needle head is by blowing
Syringe needle drive mechanism drives.Specifically, blow needle body is driven by blow needle head drive mechanism, because blow needle head is fixed with blow needle body
Connection, thus by blow needle body together with blow needle head lift, and the up-down mode of blow needle head have it is following two：First, by as blowing
The action of the cylinder of syringe needle drive mechanism and make blow needle head lift；Second, the work by the oil motor as blow needle head drive mechanism
Blow needle head is set to lift clockwise or counterclockwise.The former is applied to be molded the inflation of small plastic hollow product, the latter
Suitable for the inflation shaping to capacious plastic hollow product.Be used for harsh and larger volume for requirement is filling
The screw thread of the oral area of the plastic hollow vessel of chemical industry or even harmful influence etc is usually internal thread, is matched therewith in a state of use
Lid just as the convex shape of inverted plug screw shape, and the screw thread covered is certainly external screw thread.Empty container in the plastic
The self-evident strong point that the inwall of oral area forms internal thread 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 product is that inner thread is blowing by blow needle device
What the blow needle head external screw thread on syringe needle was formed.
For example foregoing CN204894486U of prior art is as a result of oil motor（Patent claims " power motor "）As blow needle
Head drive mechanism, because 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 part associated with oil motor is very harsh, fragile in use.Furthermore oil
The oil pipe pipeline of motor is more and complicated, can occur oil liquid leakage situation every now and then in use, on the one hand to the suitable of production
Profit is had an impact, and on the other hand adds workload to daily manage and protect.And then because the precision of oil motor is difficult to control,
Thus cause the screw thread of the oral area of plastic hollow product（Foregoing inner thread）Quality can not ensure, thread occurs when serious
Rotten tooth or collapse dental phenomenon, cause whole product rejection.
For above-mentioned prior art, the applicant has made lasting exploration and design repeatedly, below will form finally
The technical scheme to be introduced, and the central laboratory in the case where taking secrecy provision in the applicant is tested, as a result
It is proved to be practicable.
