The working principle of the auxiliary pressing device 3 for the plastic film roll packaging bag is as follows: when the plastic film reel reaches the position of the pressing block 3-1 under the pushing action of the pushing linear cylinder 37, the pressing block 3-1 moves downwards, and the pressing plate 3-7 originally positioned below the left bagging machine mounting plate 1 moves upwards by utilizing the lever principle and extends out of the surface of the left bagging machine mounting plate 1; then, the plastic film roll continuously moves forwards until the plastic film roll moves to the position of a pressing plate 3-7, the pressing plate 3-7 is turned outwards by taking a pin shaft connected with a pressure rod connecting plate 3-6 as a folding point under the pushing action of the plastic film roll, and at the moment, the pressing plate 3-7 presses the lower end of the opening of the packaging bag, so that the lower opening of the packaging bag is prevented from being turned up due to friction between the plastic film roll and the lower opening of the packaging bag, and the pressing of the plastic film roll is influenced; finally, the plastic film reel is completely pushed into the packaging bag along the pressing plates 3-7 under the pushing action of the pushing linear cylinder 37, and the packaging process is completed.
The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any way. It will be understood by those skilled in the art that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
