In one embodiment, the bag opening device further includes a base 1 , and both the fixing plate 8 and the bag opening cylinder 6 are pivotally connected to the base 1 .

In one embodiment, the base 1 is further provided with a guide plate 12 , the guide plate 12 is provided with a guide groove 11 , and the exposed part of the pin shaft 10 is provided in the guide groove 11 . On the one hand, the guide groove 11 can also provide a guiding function, and on the other hand, it can also provide support for the movable plate 5 and the fixed plate 8 .

In one embodiment, the base 1 is also provided with a bag unloading cylinder 21, the bag unloading cylinder 21 is arranged on one side of the fixed plate 8 and the movable plate 5, and the end of the push rod is provided with a push plate 24, and the push plate 24 Driven by the bag unloading cylinder 21, it can extend into the space between the fixed plate 8 and the movable plate 5 when they are at the maximum opening position, so as to push out the packaging bag in the space. After the packaging bag is filled and sealed, the bag unloading cylinder 21 works to push it out from between the movable plate 5 and the fixed plate 8 .

In one embodiment, the base 1 is further provided with a bag unloading slideway 22, and the bag unloading slideway 22 is located on the other side of the fixed plate 8 and the movable plate 5, and is used to make the packaging bags that fall on the surface slide down to the conveyer. Take 23 on. In this way, the packaging bag containing the medicament can be prevented from falling directly onto the conveyor belt 23 to cause damage to the packaging bag, and the yield of the whole filling process is improved.

In one embodiment, a quantitative filling device is also included. The quantitative filling device includes a quantitative barrel 3 and a solenoid valve 4 arranged on the outlet pipe of the quantitative barrel 3.
