Description
Technical Field
The invention relates to an automatic nozzle guiding system of a high borosilicate glass kettle and a control method thereof, belonging to the field of glassware mechanical equipment.
Background
The spout on the side of the high borosilicate glass kettle is generally heated by heating the spout position of the glass kettle, then the melting part of a glass rod with one end heated is adhered to the heated spout position, simultaneously, air is blown into the glass kettle, the glass rod is pulled according to the shape of the spout, and after the spout guiding action of the glass kettle is completed, the connecting part of the glass rod and the spout is melted by flame, so that the glass rod is separated from the spout. The method of respectively forming and bonding the spout of the kettle body can leave wrinkles, so that the current procedure can only be manually completed by workers, and the position of the spout leading part, the shape of the spout and the angle of the spout of each kettle can be different, so that the quality of the glass kettle is poor. And because manual processing is completely adopted, the efficiency is low, the batches cannot be completely unified, and the batch production cannot be realized.
The prior and pending related patents are focused on solving the problem of forming borosilicate glass pots of the cold pot type with only a single top spout, but not on forming spouts of teapot type with spouts on the sides. For example, an automated borosilicate glass kettle production system (application No. 201711453513.8) proposes a production system in which a blowing machine and a forming mold are matched with each other, but can only produce a borosilicate glass kettle of a cold water kettle type having a single top kettle opening. "a molding device for spout of borosilicate glass kettle (application number: 201711455885.4)" proposes that the molding operation of the spout of the borosilicate glass kettle is realized by a rotary disc and an extrusion molding mechanism, but the molding device is still only suitable for the borosilicate glass kettle with a single top spout. In consideration of the vacancy of the existing patent, the invention designs the automatic spout guiding system of the high borosilicate glass kettle by a set of comprehensive method, can perform spout guiding operation of the side spout on the high borosilicate glass kettle of a teapot type with the spout on the side surface, replaces manual processing, improves the efficiency and realizes uniform appearance and quality of products in different batches.
