Problems solved by technology

[0004] In actual use, because there is air remaining in the powdered food (such as milk powder, soybean powder, etc.) stored in the tank, and the powder cannot be completely compacted during the vacuuming process, that is, there is residual oxygen in the powder , then in the process of nitrogen filling, too much residual oxygen is mixed into the nitrogen gas, which leads to the substandard residual oxygen in the sealed tank. There are improvements in the existing technology

Embodiment Construction

[0042] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0043] Such as figure 1 As shown, a vacuum-pumping and nitrogen-filling sealing machine includes a frame 1 on which a conveying track 2 is erected, and the feed end 24 and the discharge end 25 of the conveying track 2 are respectively connected with a feed line body 11 and a feed end 25. The discharge line body 12 is provided with a perforating device 3 , an upper cover device 4 and a sealing device 5 sequentially from the feed end 24 to the discharge end 25 of the conveying track 2 . The tank body and the cover body are transported to the sealing device 5 via the conveying track 2 and the upper cover device 4 respectively, and the vacuuming operation and the nitrogen filling operation of the tank body are completed through the sealing device 5, and then the sealing operation of the tank body and the cover body is completed. In this way, the automatic operat...

Abstract

The invention discloses a vacuumizing and nitrogen filling sealing machine and relates to the technical field of can sealing machines. The vacuumizing and nitrogen filling sealing machine comprises anorganic rack and a conveying track. A sealing device is arranged on the rack, a perforating device is arranged at the feed inlet of the conveying track on the rack and comprises a mounting rack, a power part and perforating parts which are driven by the power part to move vertically are arranged on the mounting rack, and the perforating parts of needle structures are matched to form a columnar structure which is matched with a tank body. Perforating and loosening effects of the perforating device are improved favorably and the problem of powder hardening is also solved favorably according tothe shape of a perforated hole. The columnar structure formed by matching the perforating parts is matched with the tank body in shape to meet the perforating and loosening operational demands of tankbodies of different shapes. By perforating and loosening powder and carrying out vacuumizing and nitrogen filling operations, a purpose of reducing the residual oxygen content in the powder in the vacuumizing operating process is achieved. Therefore, the residual oxygen content in the tank body after vacuumizing and nitrogen filling meets the demand.

Description

technical field [0001] The invention relates to the technical field of can sealing machines, in particular to a vacuum-pumped nitrogen-filled sealing machine. Background technique [0002] According to the degree of automation, can seaming machines can be divided into two categories: semi-automatic can seaming machines and fully automatic can seaming machines. It can vacuumize and fill the cans with nitrogen and seal the cans such as iron cans, aluminum cans, tinplate cans and plastic cans. [0003] The existing authorized notification number is the Chinese patent of CN105151379B, which discloses a fully automatic PET plastic can vacuumizing nitrogen filling sealing machine, including a frame, which is equipped with a can pulling mechanism, a lid feeding mechanism, a sealing mechanism and a can feeding mechanism. mechanism, and a vacuum system and a nitrogen filling system are provided at the sealing mechanism. The can pulling mechanism includes a can pulling robot and an ...
