Description

Vacuum pumping mechanism of bag feeding type packaging machine Technical Field The utility model relates to a packaging machine, in particular to a vacuum pumping mechanism of a bag feeding type packaging machine. Background The vacuumizing mechanism is an important component of the bag feeding type packaging machine. The vacuum pump is mainly used for vacuumizing the packaging bag filled with materials. The Chinese patent document (publication No. CN 222698885U; publication No. 2025, 4, 1) discloses a multi-station high-speed bag feeding type vacuum packaging machine, which comprises a machine base, and is characterized in that a filling and discharging system and a vacuum pumping system are arranged on the machine base, the filling and discharging system comprises a first rotary table, a plurality of clamping components annularly arranged on the first rotary table, a bag taking mechanism, a bag feeding mechanism, a bag opening and supporting mechanism, a discharging station and a switching mechanism, the bag taking mechanism, the bag feeding mechanism, the bag opening and supporting mechanism, the discharging station and the switching mechanism are sequentially arranged on the periphery of the first rotary table, the vacuum pumping system comprises a second rotary table, a plurality of vacuum chambers annularly arranged on the second rotary table, a vacuum pumping mechanism, a heat sealing mechanism and a discharging station, the switching mechanism is connected between the first rotary table and the second rotary table, and the switching mechanism is in transmission fit with the vacuum chambers in front of the vacuum pumping mechanism. The technical scheme has the defects that in order to vacuumize the packaging bags filled with materials and continuously sent by the transfer assembly, a plurality of groups of vacuumizing assemblies are arranged on the turntable in a surrounding mode to vacuumize in the rotating process after receiving materials, the required vacuumizing assemblies are arranged in a large number, the structure is very complex, the production and assembly and the later maintenance operation are very troublesome, the whole volume is very large, the required occupied area is very large, and the arrangement in a workshop is inconvenient. Disclosure of utility model In view of the shortcomings of the background art, the technical problem to be solved by the utility model is to provide a vacuum pumping mechanism for a bag feeding type packaging machine. For this purpose, the utility model is realized by adopting the following scheme: The vacuum pumping mechanism of the bag feeding type packaging machine is characterized by comprising a left vacuum seat and a right vacuum seat, wherein an intermediate vacuum seat is arranged between the left vacuum seat and the right vacuum seat, the intermediate vacuum seat is connected with a first movable driving assembly, the intermediate vacuum seat can enclose a left vacuum pumping cavity with the left vacuum seat, the intermediate vacuum seat can also enclose a right vacuum pumping cavity with the right vacuum seat, clamping assemblies and heat sealing assemblies are arranged in the left vacuum seat and the right vacuum seat, a left air pumping joint is arranged on the left vacuum seat, and a right air pumping joint is arranged on the right vacuum seat. The first movable driving assembly comprises a first air cylinder, and a piston rod of the first air cylinder is connected with the middle vacuum seat.
