Volume-stabilizing device

Abstract

The invention provides a volume-stabilizing device. The device comprises a liquid level detection buoy sleeved outside the tail end of a liquid-filled pipe and is characterized in that: a volume-stabilizing sleeve is sleeved outside the top end of the liquid-filled pipe; and the outer diameter of the volume-stabilizing sleeve is less than the inner diameter of a cylinder made of a packaging material so that a gap is reserved between the volume-stabilizing sleeve and the cylinder. The invention provides the volume-stabilizing device applied to liquid food packaging machinery. The effect of an external force on the inside of a package is reduced so that a negative pressure is prevented from being produced on a packaging area, the shape of a packaging material pipe is improved and the formation of the package can be ensured without applying the external force or a high pressure to a product or in the product. Simultaneously, the device provided by the invention does not need sealing or sliding joint with the packaging material pipe so that the effect of material residues brought by friction on the product is avoided. Lastly, the device provided by the invention has the advantages of simple structure, convenient cleaning and very reliable work.

Description

technical field [0001] The invention relates to a capacity stabilizing device used in liquid packaging. Background technique [0002] Liquid packaging machinery must be perfused when it is packaged with flexible materials. When this type of machinery is perfused at high speed, it will be subjected to uniformly spaced resistance from the outside, and the perfused liquid will move up and down with this uniformly spaced resistance. The result is the instability of high-speed perfusion. In order to ensure the stability of perfusion, a volume stabilization device is usually used, but it is customary in the industry to refer to this device as a product filling tube. This expression is not appropriate, it should be an auxiliary mechanism of the filling tube, and its main purpose is to ensure the stability of perfusion. [0003] There are many common configurations of capacity stabilizing devices. One has a downwardly open end at the end of the fill tube, the secondary open end b...

Problems solved by technology

It has been found that when liquid packaging machinery works at high speeds (greater than 16,000 packs per hour), there is not enough time between successive packaging operations and sealing operations to allow the liquid to The product is filled into the deformed material by its own gravity, and the resulting low pressure will greatly reduce the capacity of the package, which will affect the appearance quality of the product

But existing devices all do not overcome above-mentioned defect
