Problems solved by technology

[0003] When storing products, the negative pressure sealed packaging needs to be pumped to make the inside of the sealed package vacuum. The existing operation method is to directly connect the pumping equipment to the sealed packaging interface for vacuuming. Due to the effect of atmospheric pressure, the inner surface of the package will be damaged. The air extraction part is closely attached to the packaged obje

Example Embodiment

[0016] Example 1

[0017] A method for negative pressure sealing and packaging includes the following steps:

[0018] 1. Fit the outer edge of the cushion on the inner surface of the sealed package 5 and the interface 6 where the air extraction device is connected, and check the air tightness of the sealed package; the cushion 4 is made of rubber and processed by molds , Is composed of an outer edge 3 and a main body part 2. The outer edge 3 is an annular sheet, and the inner ring is connected to a hollow cylinder of a certain thickness, namely the main body part 2. The top of the main body part is evenly distributed with four U-shaped grooves 1 opposite each other. Such as figure 1 Shown

[0019] 2. When pumping negative pressure, the air extraction device is directly connected to the sealed packaging interface, and the interface and the packaged object establish an air flow channel through a cushioning cushion. The four grooves can allow the surrounding air to circulate and ensure...

Abstract

The invention belongs to the field of aviation ammunition, and in particular relates to a negative pressure sealing and packaging method. First, attach the outer edge of the air cushion to the interface between the inner surface of the sealed package and the air pumping device, and conduct an airtightness test on the sealed package; The packaged object establishes an airflow channel through a cushion of air, and the four grooves allow the surrounding gas to circulate, ensuring that the gas can be continuously extracted; the negative pressure sealing packaging method of the present invention improves the working efficiency of negative pressure pumping, and it is convenient to store in a negative pressure seal. Measure the air pressure value inside the package and observe the internal gas humidity.

Description

technical field [0001] The invention belongs to the field of aviation ammunition, and in particular relates to a negative pressure sealing and packaging method. Background technique [0002] Negative pressure sealing packaging is a commonly used packaging technology for equipment moisture-proof packaging at present. The equipment is sealed and packaged with low moisture permeability materials to isolate the equipment from the outside natural atmosphere, so as to prevent or delay the rust and mildew of the equipment during storage and transportation, thereby avoiding moisture, Corrosion and mold growth, and regular maintenance is required during storage and transportation to achieve the purpose of long-term sealing of equipment. [0003] When storing products, the negative pressure sealed packaging needs to be pumped to make the inside of the sealed package vacuum. The existing operation method is to directly connect the pumping equipment to the sealed packaging interface for...
