Description

Special body make-up machine of oral liquid medicinal polyester bottle Technical Field The invention relates to the technical field of medical polyester bottle body molding, in particular to a special bottle body molding machine for an oral liquid medical polyester bottle. Background The polyester bottle for oral liquid medicine is widely applied to the packaging field of medicinal preparations such as oral solution, syrup, oral liquid and the like by virtue of the core advantages of stable material, excellent sealing performance, no toxicity, no smell and the like, and the molding quality directly determines the storage safety and the use reliability of the medicinal preparations, so that extremely severe industry standard and use requirements are provided for the molding precision, the sealing performance and the running stability of a bottle body molding machine. At present, an oral liquid medicinal polyester bottle body forming machine in the prior art has the core working principle that a blow pipe is driven by a blow molding module to be in butt joint with a mold closing mold and a bottle blank, so that the blow molding process of the bottle blank is completed. However, in the actual mass production process, the forming machine is limited by the inherent defects of the existing structural design, and the forming machine still has a plurality of outstanding technical problems, which are not broken through by the innovative means in the prior art, so that the forming quality and the production efficiency of the medicinal bottle are severely restricted, and the use requirements of the industry cannot be met: The butt joint parts of the air blowing pipe, the die closing die and the bottle blank of the existing forming machine are mostly provided with a single sealing structure, a multistage sealing protection system is not constructed, reliable sealing of a blow molding air path cannot be realized, gas leakage phenomenon is very easy to occur in the high-pressure blow molding process, and further defects of incomplete bottle body forming, uneven wall thickness distribution and the like are caused, so that the sealing performance of a medicinal bottle is directly influenced, and the sealing performance of the medicinal bottle cannot reach relevant industry standards of the oral liquid medicinal bottle. The butt joint of the blow molding module, the die closing die and the bottle blank only depends on a simple mechanical positioning structure, an air pressure auxiliary locking mechanism is not arranged, in the high-pressure blow molding process, under long-term use, the impact force generated by high-pressure air causes the relative offset between the blow pipe, the bottle blank and the die closing die, so that the quality defects of bottle body molding deflection, bottle opening deformation and the like are caused, the rejection rate of products is obviously improved, and the production cost of enterprises is increased. The plastic waste recycling system which is lack of adaptation is low in resource utilization rate and pollutes production environment, an integrated recycling structure is not arranged for plastic waste such as bottle blank leftover materials and unqualified formed waste bottle bodies generated in the blow molding process of the existing molding machine, manual collection and external transfer treatment modes are adopted, manual operation strength is increased, waste collection is not timely and is easy to cause pollution of a production site, meanwhile, waste is not subjected to on-site preliminary treatment and is directly transferred, the problems of wetting, pollution, uneven crushing and the like of the waste are easy to occur, purity and efficiency of waste recycling are reduced, and waste treatment and raw material purchase cost of enterprises are greatly increased. The invention provides a special bottle body forming machine for an oral liquid medical polyester bottle, which solves the problems.
