Background

The existing packaging bag is basically fresh and needs few bottom holes, the opening of the packaging bag arranged in the packaging barrel is basically upward, and when the packaging material in the packaging bag is taken out, the packaging bag is basically taken out from the packaging bag. The following problems exist when liquid and viscous fluid materials are taken out from the upper part of the packaging bag or pumped out:

(1) and the fluid in the packaging container is more remained, which causes waste.

(2) And if the waste is dangerous, the treatment cost of the dangerous waste is increased.

(3) And the energy consumption of the fluid pump is high during operation.

(4) Some fluids can also generate VOCS gas, and when the equipment is installed, environmental protection departments require the installation of VOCS gas collecting and processing devices, so that the cost is high.

(5) When viscous fluid such as ink, grease, resin, glue and the like is extracted from the upper surface of the packaging container, a sucker is usually adopted, a fluid pump is installed on the sucker, downward pressure needs to be applied to a pressure plate in the using process, the viscous fluid inside the packaging container often overflows along the periphery of the pressure plate, and the pollution of the viscous fluid and the waste of materials are caused. In addition, the sucker is generally made of non-metal materials for sealing, fatigue damage or aging can occur in the using process, the sealing is not tight, and high replacement cost is caused when the sucker needs to be replaced. Meanwhile, the periphery of the sucker is sealed by non-metal materials, and certain extrusion force is required between the sucker and a packaging container, so that the packaging container is difficult to replace and long in time.

Therefore, it is necessary to provide a further solution to the above problems.
