Automatic device used for blowing making of bottle blank of vertical type transfusion bag

Abstract

The invention discloses an automatic device used for blowing making of a bottle blank of a vertical type transfusion bag and belongs to the technical field of bottle blank conveying. The automatic device comprises a bottle blowing device and an injection molding device, and is characterized in that the bottle blowing device and the injection molding device are arranged in parallel, and a bottle blank transferring system is installed between the bottle blowing device and the injection molding device; and the bottle blank transferring system comprises a discharging mechanical device used for taking out the bottle blank after being subjected to injection molding in the injection molding device, a circulating disk used for temporarily storing the bottle blank, and a feeding mechanical device used for conveying the bottle blank on the circulating disk to the bottle blowing device, and the feeding mechanical device is on a large chain following clamp. Multiple devices are integrated, high automation is achieved from injection molding to bottle blowing, and no manual intervention exists in the whole process. The whole transferring process of the bottle blank is free of mutual collision, ordered arranging and conveying is achieved, the risk that foreign matter is introduced in the bottle blank transferring process is reduced, and the quality control is guaranteed in the product production process.

Description

technical field [0001] The invention relates to the technical field of preform conveying, in particular to an automatic device for blowing preforms of upright transfusion bags. Background technique [0002] In the production of plastic container infusion products in large infusion pharmaceutical companies, the company usually adopts a two-step method to make infusion containers. After the preforms are injected into the mold at the injection molding station, the mold will drop the preforms randomly into the network chain conveyor, and the multi-segment network The combination of chain conveyors sends the preforms to the upper embryo hopper of the blowing bottle, and then sends them to the large chain accompanying fixture of the blowing machine through the preform introduction frame, the embryo separation tray and the upper embryo finger chain of the blowing machine. At the same time, in order to ensure the uniformity of the embryo temperature, An FFU unit is installed on the ...

AI Technical Summary

Problems solved by technology

[0004] After the preforms fall off from the injection mold, they will collide on the shuttle groove under the mold of the injection molding machine, and there will be friction between them. After falling into the chain conveyor, they will be arranged in disorder, because the preforms will have strong static electricity after falling off the mold. , during the transfer process of the preform, it will absorb and come into contact with foreign matter, causing quality risks

After the preform is transferred to the upper embryo hopper, it will rub against the inner shape of the hopper. In the process from the upper embryo hopper to the large chain accompanying fixture, it will pass through multiple mechanisms and air blowing. Intervention with high risk of electrostatic attraction of foreign matter and equipment introduction of foreign matter

At the same time, the installation positions of the blow molding machine and the injection molding machine in this connection mode are mostly on a straight line, installed in two rooms, and the equipment is controlled separately, requiring many operators.
