A plastic infusion bottle lifting ring welding device

Abstract

The invention discloses a device for welding plastic infusion bottle hanging rings. The device comprises a rack assembly (1), a conveying mechanism (2) and a hanging ring welding mechanism (3), wherein the conveying mechanism (2) is mounted on the rack assembly (1); a follow fixture (4) is fixedly mounted on the conveying mechanism (2) and is used for fixing plastic bottle blanks; the hanging ring welding mechanism (3) is arranged right above the follow fixture (4) and is fixedly installed on the rack assembly (1), a hanging ring welding slot (5) is formed in a part, opposite to the follow fixture (4), on the hanging ring welding mechanism (3) and is used for heating and fusing apexes of the plastic infusion bottle blanks assembled with hanging rings. The device can be used for automatically welding the plastic infusion bottle hanging rings, and is simple in structure, stable in performance and high in production efficiency.

Description

technical field [0001] The present application relates to the field of medicine, in particular to a welding device for hanging rings of plastic infusion bottles. Background technique [0002] Plastic infusion bottles are mostly used in medical treatment. In order to facilitate use, a suspension ring is installed at the bottom of the plastic infusion bottle so that the plastic infusion bottle can be directly hung upside down. Generally, the plastic infusion bottle suspension ring is fixed by welding. [0003] There are two main ways to weld the rings at the bottom of the existing plastic infusion bottles: one is to automatically add the rings and weld them before the plastic bottle preform is blown out of the bottle. On the plastic bottle preform, the preform with the hanging ring is rotated, and the welding mechanism corresponding to the plastic bottle preform and the heating tube is respectively corresponding to the welding ring according to the established cam track. The d...

[0003] There are two main ways to weld the rings at the bottom of the existing plastic infusion bottles: one is to automatically add the rings and weld them before the plastic bottle preform is blown out of the bottle. On the plastic bottle preform, the preform with the hanging ring is rotated, and the welding mechanism corresponding to the plastic bottle preform and the heating tube is respectively corresponding to the welding ring according to the established cam track. The disadvantage of this ring welding method is the structure Complexity, high manufacturing and use costs, and difficult adjustment and maintenance. In addition, only one of the ring welding mechanisms has a temperature sensor to control and adjust the temperature of all ring welding mechanisms, which is difficult to operate and affects quality.

The other is to weld the rings of the plastic infusion bottles by fixing the bottle cover manually, placing the bottle manually, and placing the rings after the plastic bottle is filled and sealed, even after the sterilization and light inspection are completed. This ring welding method The disadvantage is that the production efficiency is too low and the operator requires more
