Description

Equal-liquid-level filling head

Technical Field

The utility model relates to a filling machinery technical field uses with the supporting use of oils liquid filling machine for a novel liquid level filling head such as filling fluid.

Background

In the production process of the existing filling machine, because of the errors of the volume and the height in the bottle body, the bottle openings are different in size, products in the same bottle type are produced in the production and filling processes, the liquid levels of the products are different, the quality of the products is questioned by consumers, and the credit of merchants is influenced. At present, the domestic liquid level filling oil nozzle can only realize single liquid level filling, and the oil nozzle has the problem of leakage after volume quantitative filling.

Disclosure of Invention

The utility model discloses a wait liquid level filling head, unnecessary liquid takes back the backward flow jar through the suction pipe after the filling, realizes the uniformity of product liquid level, remains the effect of the first quantitative liquid of traditional filling vacuum antidrip problem after adorning simultaneously again.

Therefore, the utility model adopts the technical scheme that:

a filling head with equal liquid level comprises a filling fixed plate fixedly connected with a filling device, wherein a filling upper pipe and an air cylinder are fixedly arranged above the filling fixed plate side by side, a filling middle pipe is fixedly arranged below the filling fixed plate, the filling middle pipe is provided with a feed inlet with a side opening and a filling lower pipe fixedly connected below, and the feed inlet is communicated with the inner cavity of the filling lower pipe; a filling piston rod which can be in up-and-down sliding fit with the upper filling pipe and freely shuttles in the filling pipe is arranged in the upper filling pipe in a penetrating manner, the filling piston rod is provided with a suck-back hole which penetrates through the upper filling pipe and the lower filling pipe, the upper end of the filling piston rod is connected with a vacuum generator, and the lower end of the filling piston rod is fixedly connected with a spherical filling inner end enclosure; the part of the filling piston rod outside the filling upper pipe is fixedly connected with the cylinder piston rod through a locking nut and a cylinder connecting plate; the method is characterized in that: the inner hole of the filling lower pipe is provided with a conical matching surface with a large upper part and a small lower part, and the spherical filling inner sealing head can be pressed and sealed with the conical matching surface; the filling lower pipe is communicated with an inner hole of the filling piston rod, and the lower end of the filling lower pipe can extend into the bottle body.

Compared with the prior art, wait liquid level filling head adopt the principle of vacuum resorption, can realize the filling of liquid, can realize the filling of high liquid level such as various bottles with unnecessary liquid suction feed back case when reaching predetermined height, can realize again that liquid does not have the dribbling phenomenon, purpose-made needle type resorption pipe is particularly suitable for the bottle filling that the bottleneck is thin. The cylinder and the filling upper pipe adopt a parallel structure, so that the maintenance is convenient; the cylinder and part of the machined parts adopt standard parts, so that the parts are easy to purchase, and a customer can purchase the parts by himself to repair and maintain.
