Description
Technical field
The present invention relates to vessel fabrication field, especially, relate to a kind of separation method for plastic containers manufacture and separator.
Background technology
Along with the implementation of China new edition GMP; the sterilizing standard of injection container manufacture is improved further; therefore in the manufacture process of this type of container; the possibility of external contamination will be reduced as far as possible, the protection being subject to gnotobasis after specifically comprising container formation, before sealing with reduce container formation to the process time sealed.This just requires that the time and space of container manufacturing operation all needs to reduce as far as possible.
Plastic containers with suspension ring as medical large transfusion bottle in the fabrication process, the housing at suspension ring place and the waste material of suspension ring mesopore need remove.For polyethylene (PE) material, because its forming temperature is relatively low, cooling is fast, draws except the frame waste material at suspension ring place and stamping-out suspension ring mesopore waste material all can realize smoothly.But for some specific materials as polypropylene (PP), due to polypropylene material, to have forming temperature relatively high, cools relatively slow feature, if at once remove waste material after container formation, because material is still in molten state, stamping-out cannot be realized.
Summary of the invention
The object of the invention is to provide a kind of separation method for plastic containers manufacture and separator, cannot inscribe to solve existing polypropylene plastic container manufacture between quantity-produced technology.
For achieving the above object, the technical solution used in the present invention is as follows:
For the separation method that plastic containers manufacture, be applicable to the separation of the waste material of eye portion in manufacturing the plastic containers of band suspension ring, this separation method comprises the following steps:
S10, the frame waste material of the suspension ring of plastic containers to be separated;
S20, the suspension ring hole waste material of the suspension ring of plastic containers to be separated.
Further, life period interval between step S10 and step S20, and the suspension ring portion of plastic containers retains area significantly reduces, so that the suspension ring hardening by cooling of plastic containers.
Further, in step S10, the entirety of the first fixed die clamping suspension ring is set, and draws the frame waste material except suspension ring outside through demoulding pin.
Further, in step S20, the outer portion of the second fixed die clamping suspension ring is set, and the suspension ring hole waste material of the second blanking die to suspension ring through being positioned at the second fixed die inside is separated to form suspension ring mesopore.
Further, plastic containers adopt polypropylene material or other similar materials to make.
According to a further aspect in the invention, additionally provide a kind of separator manufactured for plastic containers, be applicable to the separation of the waste material of eye portion during the plastic containers of band suspension ring are manufactured, comprise:
First separation station, the frame waste material for the suspension ring to plastic containers is separated;
Second separation station, the suspension ring hole waste material for the suspension ring to plastic containers is separated; And
Transmit station, for transmitting plastic containers between the first separation station and the second separation station.
Further, the first separation station comprises the first fixed die for integral retaining suspension ring, and for the demoulding pin of the frame waste material that excises suspension ring outside.
Further, the second separation station comprises second fixed die in the outer portion for clamping suspension ring, and is separated to the suspension ring hole waste material of suspension ring the second blanking die forming suspension ring mesopore, the second blanking die be positioned at the second fixed die inside and through air cylinder driven.
Further, the second blanking die is columniform stamping-out head.
The present invention has following beneficial effect:
The present invention is used for separation method and the separator of plastic containers manufacture, is separated and is divided into two steps to carry out: the first step, is separated the frame waste material of suspension ring by the waste material of the plastic containers manufacture by traditional band suspension ring; Second step, is separated the suspension ring hole waste material of suspension ring.Owing to first drawing the frame waste material except suspension ring, plastic containers be passed to next station carry out the stamping-out of suspension ring mesopore time, eye portion material has reduced a lot, add through the one-step cooling time interval, remaining part is hardening by cooling, the adhesion phenomenon avoiding suspension ring stamping-out in the molten state causes stamping-out failure, thus ensure that the continuous of production process, improves the working (machining) efficiency of plastic containers.
Except object described above, feature and advantage, the present invention also has other object, feature and advantage.Below with reference to figure, the present invention is further detailed explanation.
