A disadvantage of such filling machines is that the filling speed is low when filling high viscosity products.
The pressure filling machine is used for filling under the pressure higher than atmospheric pressure, and can also be divided into two types: one is that the pressure in the liquid storage cylinder is equal to the pressure in the bottle, and the liquid flows into the bottle by the self-weight of the liquid to be filled, which is called isobaric filling; the other is that the pressure in the liquid storage cylinder is higher than the pressure in the bottle, the liquid flows into the bottle by the pressure difference, and the method is mostly adopted by a high-speed production line. In any method, the liquid level of the material is pressurized, so that the pressure difference is generated between the pressure of the material liquid and the atmospheric pressure, and the material is filled by utilizing the pressure difference.
Due to pressurization, the requirement on the sealing performance and the pressure resistance of a container for containing the material liquid is high. Generally, the larger the tank for holding the feed liquid, the higher its pressure resistance requirement.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be further described below.
As shown in fig. 1 and fig. 2, the present invention provides a negative pressure filling machine, which comprises a negative pressure component 1, a liquid storage tank 2, a negative pressure cavity 3 and an exhaust pipe 4; wherein, the negative pressure cavity 3 is erected in the liquid storage tank 2, and the negative pressure component 1 is communicated with the negative pressure cavity 3 through a negative pressure manifold 8; the bottom of the liquid storage tank 2 is provided with a plurality of transfusion holes; each infusion hole is provided with a filling head 6 connected with a product bottle; one end of the exhaust pipe 4 is communicated with the negative pressure cavity 3; the other end of the exhaust pipe 4 penetrates through the filling head 6 to be communicated with the inner cavity of the external product bottle.
In the present embodiment, the negative pressure module 1 includes a gas-liquid separation tank 11 and a vacuum pump 12; the vacuum pump 12 is connected with the gas-liquid separation tank 11 through a pipeline; the gas-liquid separation tank 11 is connected to the negative pressure manifold 8.
In this embodiment, a product recovery pump 7 is also included; the feeding end of the product recovery pump 7 is communicated with the gas-liquid separation tank 11 through a pipeline; the discharge end of the product recovery pump 7 is communicated with the inner cavity of the liquid storage tank 2 through a pipeline.
In the present embodiment, a liquid level meter is provided in the gas-liquid separation tank 11.
