[0028] Embodiment 1:

[0029] Combination Figure 2 and Figure 4The filling bottle conveying mechanism 21 includes a support frame 211 fixedly arranged on one side of the outer frame 1 of the plug filler. Two groups of support frames 211 are provided. A transmission belt 213 is rotatably arranged between the two groups of support frames 211. One side of the transmission belt 213 is connected to a built-in support roller 214. The support frame 211 fixes a conveying motor 212, and the conveying motor 212 drives the transmission belt 213 to rotate to realize the conveying of the filling bottles.

The lifting driver 311 is provided with two groups. A lower pressure rod 312 is connected between the two groups of lifting drivers 311. Six groups of nozzle plug assemblies 33 are arranged side by side on the lower pressure rod 312. The two groups of lifting drivers 311 drive the lower pressure rod 312 to rise and fall, thereby driving the nozzle plug assembly 33 to squeeze the filling bottle mouth to realize filling.

[0034] The bottle mouth fixing assembly 32 includes a clamping fixing frame 321 fixedly connected to the inside of the outer frame 1 of the straight plug filler, and a clamping drive 322 arranged on both sides of the clamping fixing frame 321. The clamping fixing frame 321 is provided with two groups of side baffles 323 and side clamps 324 respectively fixed on one side of the two groups of clamping fixing frames 321. The side clamps 324 are provided with filling bottle positioning openings 3241.

The fixing nut 331 fixes the nozzle plug assembly 33. The thick spring 333 provides a buffer force for the straight plug extrusion of the filling tube 332 to prevent the bottle mouth from being deformed due to excessive extrusion force. The sleeve block 334 and the caliber pressing fixing piece 335 cooperate to realize the opening and closing of the filling side opening 3321.

[0036] Filling side openings 3321 are provided on both sides of the lower end of the filling tube 332, and a sleeve stopper 3341 is provided at the lower end of the sleeve block 334 for slidingly limiting the caliber pressing fixture 335.
