Patent Description:
At present, there are two main methods to remove a nest inner membrane. One method is to tear the nest box inner membrane directly from a nest box by a clip. Because the nest box inner membrane is glued to an upper surface of the nest box, dust particles are easy to be generated in the tearing process, and there is a great risk of pollution of the medicine bottle in the nest box. The other method is to heat the nest box inner membrane, first heat the nest box inner membrane to enable the glue to be melt, and then remove the nest box inner membrane. This method greatly reduces the generation of dust particles and has higher recognition. In the method of heating the nest box inner membrane, a heating frame of an inner membrane removing device and a nest box inner membrane removing portion of the inner membrane removing device are formed in one, and the heating frame and the nest box inner membrane removal portion suck the nest box inner membrane by turning over. The inner membrane removing device has disadvantages as follows: <NUM>, a nest box inner membrane removal driving portion is fixed on the heating frame, that is, a power source is located above the nest box, the power source causes a risk of pollution of the medicine bottle in the nest box; <NUM>, when the heating frame is turned over, the nest box inner membrane is sucked to be removed at the same time, if dust particles are generated during the turning process, the dust particles may fall directly to a mouth of the medicine bottle, which also causes the risk of pollution of the medicine bottle; <NUM>, nest box inner membrane heating, nest box inner membrane removal and lining paper are concentrated in one station, so it takes a long time, which affects a production efficiency; <NUM>, the heating frame needs to be turned over and the heating frame is heavy, which results in complex structure, large volume and high energy consumption.
