Abstract
The plastic moulding machine has blowing stretcher comprising mould assembly, stretching and blowing mechanism, etc.; and preheater comprising preheating device and preheated pipe blank conveying mechanism. The stretching and blowing mechanism and the preheated pipe blank conveying mechanism are circular stepped rotation mechanisms constituted separately by driving wheel, driven wheel, chain with pipe blank support, etc. The present invention has independent preheater and stretching and blowing mechanism, can be used flexibly and makes it possible to realize automatic production.
Description
The present invention relates to the process equipment of hollow plastic container, particularly relate to preheating and the stretch blow plastic container forming machine of endless-walk operation separately.
With plastics (polyester) is raw material, produce hollow container through injection, stretching, blowing, as various beverage bottles, bottle for cosmetics etc., its main process equipment has two types: a class is a fully automatic forming machine, this machine work in-process is finished on same machine from the former overall process of expecting formed product, comprises injection moulding and stretch-blow etc., as Chinese patent 86104834.2, name is called " injection stretching blow molding machine ".The characteristics of this kind equipment are the production efficiency height, and operating personnel are few, and product quality can guarantee.But the shortcoming of its existence is a complex structure, and manufacture difficulty is big, costs an arm and a leg, be difficult in, apply in the small enterprise.Another kind of is the two-step method former, its pipe injection moulding, and secondary preheating pipe again through the stretch blow moulding, relates to injection machine, preheater and stretch blow machine five equilibrium and is casually arranged with and is equipped with, as Chinese patent: 88221296.6, name is called " equipment of producing plastic containers ".Injection machine in this kind equipment is a universal machine, and preheater is relatively simple for structure, and the stretch blow body is long-pending less, easy to manufacture, and with the injection moulding pipe after processing a certainly, the production and the stretch blow moulding can be changed places, particularly can be put into Soft Drinks Plant and go processing, the production flexibility is big.But its shortcoming is the per pass operation error is arranged, the percent defective height, operating personnel are many, inefficiency.Therefore, invented another kind of type at present, preheater and stretch blow machine are combined, the bottle base of preheating directly enters the moulding of stretch blow machine, and as Chinese patent 96217151.4, name is called " automatic transport heating stretch blowing machine ".This machine reality can be classified as dispersing apparatus, but production efficiency improves operating personnel's minimizing.The preheater and the stretch blow machine of this equipment are same conveying mechanisms, the pipe of circular flow is arranged in preheating and the stretch blow and contradiction occurs, this is because the volume difference in size of plastic containers is very big, if run into the production small container, the pipe of arranging in preheating procedure is many, and its stretch blow operation has little time processing, and the pipe after the preheating is overstock, if in the preheating road, reduce the pipe number of the arrangement, again electric energy caused waste.On the contrary, when running into the processing bulk container, the mould of stretch blow machine is big, require the pipe spacing also big, at this moment enter the arrangement of heating the road and will make spacing, must lay less at pipe, so, the pipe that the preheating road comes out can not satisfy stretch blow machine needs, if prolong the length in preheating road, can make machine volume very huge again.
The purpose of this invention is to provide a kind of preheating, stretch blow circulates respectively, and is respectively step-by-step movement circulation, the plastic hollow make-up machine of working in coordination again.
The present invention's technical scheme two and the step-by-step movement preheating stretch blowing plastic forming machine is: form stretch blowing machine by die assembly and Stretch and Blow Mechanism etc., form preheater by preheating device and economizer bank blank conveying mechanism, it is characterized in that having in the stretch blowing machine independently stretch blow conveying mechanism, stretch blow conveying mechanism and economizer bank blank conveying mechanism are formed with driving wheel, driven pulley and pitch chain or chain etc. separately, the pipe supporting base is installed on pitch chain or the chain, and stretch blow conveying mechanism and economizer bank blank conveying mechanism are respectively step-by-step movement circulation rotating mechanisms.
Two and step-by-step movement preheating stretch blowing plastic forming machine of the present invention, both driving wheels of its stretch blow conveying mechanism and economizer bank blank conveying mechanism are driven by stepper motor or connect a calibration eccentric wheel in a side of driving wheel, and the calibration eccentric wheel links to each other with power by transmission mechanism.
Two and step-by-step movement preheating stretch blowing plastic forming machine of the present invention, its stretch blowing machine and preheater are installed on the same support or are installed in separately on the support.Promptly can same support, also can two supports.
Two and step-by-step movement preheating stretch blowing plastic forming machine of the present invention, its stretch blowing machine are installed in line with preheater or are become V font angle to install.
Two and step-by-step movement preheating stretch blowing plastic forming machine of the present invention, traction body is installed in the below of its stretch blow conveying mechanism, traction body is one or two, and traction body and driving wheel, driven pulley and pitch chain or chain are formed traction rotation loop wire, and traction body is traction wheel or carry-over pinch rolls or traction pressing plate.
The invention discloses a kind of automanual hollow plastic container make-up machine, its main feature is that step-type conveying mechanism is arranged in the stretch blow machine, and step-type conveying mechanism is arranged again in the pipe preheater, and both conveying mechanisms need to match according to design.The purpose of this design is that the pipe placement spacing that enters the stretch blow machine is decided by the stretch blow conveying mechanism, and with pipe preheating conveying mechanism on the density placed of pipe irrelevant, preheater uses and becomes flexible, convenient, a particularly applicable preheater, the pipe preheating of supplying several stretch blow machines like this.Pipe robotic arm after the preheating or manually move on on the stretch blow machine conveying mechanism.So preheating, the existing independence of stretch blow can realize automated production again.
Fig. 1 is the two and step-by-step movement preheating stretch blowing plastic forming machine schematic diagram of the present invention;
Fig. 2 is that stretch blowing machine A of the present invention is to a kind of embodiment schematic diagram;
Fig. 3 is that preheater B of the present invention is to a kind of embodiment schematic diagram.
Below in conjunction with Fig. 1-Fig. 3 embodiments of the invention are done detailed explanation.
