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...

Examples

Embodiment Construction

[0011] refer to figure 1 , figure 2 , image 3 It can be seen that the multi-extraction packaging bag vacuum pumping device of the present invention includes a turntable 1 and a gas distribution disc 2, and the gas distribution disc 2 is connected to the vacuum chamber part 4 (corresponding to the number of vacuum tubes) through vacuum tubes 3 (several) , the gas distribution plate 2 is composed of a gas distribution upper plate 21, a gas distribution middle plate 22, and a gas distribution lower plate 23, and a first vacuum passage 24, a second air passage, Vacuumizing channel 25, semi-vacuumizing channel 26, first vacuuming groove 27, second vacuuming groove 28, semi-vacuuming through-hole 29 (several pieces) are also correspondingly provided on the gas distribution intermediate plate 22 . That is: the first vacuum channel 24 corresponds to the first vacuum channel 27 , the second vacuum channel 25 corresponds to the second vacuum channel 28 , and the semi-vacuum channel...
