Problems solved by technology

[0002] At present, packaging bags are generally divided into three-side sealing bags, four-side sealing bags, special-shaped bags, M-shaped packaging bags, etc. In the process of material filling and packaging, in order to prolong the shelf life of materials, the packaging bags are vacuumed after filling. However, it is only limited to a short-term high-pressure vacuum pumping, which has a large suction force and consumes a lot of energy, which increases the risk of overflow due to the flow of water in the packaging bag, so that the shelf life of the material cannot be guaranteed, and it is easy to cause the material to expire. Waste and other situations will adversely affect packaging filling and packaging quality

Abstract

The invention discloses a multi-extraction type packaging bag vacuumizing device which comprises a rotating disc (1) and an air distribution disc (2). The air distribution disc is connected with vacuum cavity parts (4) through vacuum pipes (3). The air distribution disc is composed of an upper air distribution disc (21), a middle air distribution disc (22) and a lower air distribution disc (23), the lower air distribution disc is provided with a first vacuumizing channel (24), a second vacuumizing channel (25) and a semi-vacuumizing channel (26) in sequence, and the middle air distribution disc is provided with a first vacuumizing groove (27), a second vacuumizing groove (28) and a semi-vacuumizing through hole (29) correspondingly. According to the multi-extraction type packaging bag vacuumizing device, the vacuum degree in the vacuum cavity parts is close to 100% through two times of continuous vacuumizing treatment at different stations, so that the vacuum degree of packaging bags in the vacuum cavity parts is guaranteed, the shelf life of materials is prolonged, the quality of the materials is guaranteed, waste caused by expiration of the materials is effectively avoided, and the material packaging quality is obviously improved.

Description

technical field [0001] The invention relates to a packaging machine, in particular to a vacuum pumping device for packaging bags. Background technique [0002] At present, packaging bags are generally divided into three-side sealing bags, four-side sealing bags, special-shaped bags, M-shaped packaging bags, etc. In the process of material filling and packaging, in order to prolong the shelf life of materials, the packaging bags are vacuumed after filling. However, it is only limited to a short-term high-pressure vacuum pumping, which has a large suction force and consumes a lot of energy, which increases the risk of overflow due to the flow of water in the packaging bag, so that the shelf life of the material cannot be guaranteed, and it is easy to cause the material to expire. Waste and other situations have adverse effects on packaging filling and packaging quality. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned...
