Liquid filling head

Abstract

The invention discloses a liquid filling head. The liquid filling head comprises a first pipe fitting, a second pipe fitting, an elastic part and an infusion pipe. The lower portion of the first pipefitting sleeves the upper portion of the second pipe fitting. The elastic part is provided with a top end and a bottom end and sleeves the first pipe fitting and the second pipe fitting. The top end abuts against the outer wall of the first pipe fitting, and the bottom end abuts against the outer wall of the second pipe fitting. The infusion pipe penetrates through through cavities of the first pipe fitting and the second pipe fitting. The lower end of the infusion pipe extends out of the second pipe fitting. According to the liquid filling head, the first pipe fitting, the second pipe fittingand the elastic piece are matched, external force is acted on the first pipe fitting, the lower end of the infusion pipe is caused to stretch out and expose out of a liquid outlet, liquid is conveyedoutwards, external force is released, the infusion pipe rebounds automatically, and the liquid outlet is closed. In addition, a first fixing disc and a second fixing disc are used for fixing hangingconnection of the infusion pipe, and disassembly and cleaning are convenient. The liquid filling head is simple in overall structure, can meet requirements for quick production, and is precise in infusion amount control.

Description

technical field [0001] The invention relates to the technical field of automatic filling heads of filling equipment, in particular to a liquid filling head. Background technique [0002] In the liquid filling production line, it is usually necessary to divide the liquid into containers such as bottles and tanks. In the existing equipment, in order to realize the sub-packaging of liquids, automatic valve bodies such as solenoid valves are usually used to control liquid sub-packaging. Faults, and for high-speed filling production lines, it is difficult to control the infusion volume of electronic valves accurately, and other auxiliary equipment is required to control the output volume, which will lead to complex equipment and increased costs. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a liquid filling head with simple structure, low cost and meeting the needs of high-speed filling produ...
