Description

Technical Field

[0001] The utility model relates to the technical field of medicine bottle sterilization, in particular to a limiting device for medicine bottle sterilization. Background Art

[0002] Liquid medicine or injection is mostly packed in ampoules. After the ampoule is filled, it needs to be sterilized. Most of the sterilization methods for bottled medicines are currently hot pressing, steam or water bath sterilization. Heat has penetrating power and sterilizes the liquid medicine in the bottle through heat conduction.

[0003] In the existing rotary water bath sterilizer, there is a cylinder 1, and a rotating device 2 is arranged inside the cylinder. The rotating device includes several rotating plates 4 which are sleeved on a sleeve rod 3. When in use, the rotating plates drive the medicine bottles installed in the rotating device to rotate for water bath sterilization. On the sleeve rod where the rotating plate is sleeved, due to the smoothness of the sleeve rod and the force generated by the rotation, the rotating plate will move on the sleeve rod, which will cause uneven fixation of the medicine bottles in the device and uneven overall rotation. Therefore, it is necessary to provide limit devices on both sides of the rotating plate to limit the rotating plate. The existing limiting device includes a limit frame, a limit disk and a limit shaft. The limit shaft passes through the limit disk and extends into the limit frame for fixation, such as Figure 1 As shown, a gasket is provided between the limit plate and the limit frame, and a shaft sleeve is provided in the limit plate and sleeved on the limit shaft. The limit device set up will wear the limit plate when the rotor deviates and squeezes the limit plate. At the same time, since the limit plate and the limit shaft are not tight enough, the limit plate will rotate to a certain extent when the rotor squeezes and wears the limit plate, and other structures including the limit shaft, the shaft sleeve, the gasket, etc. will be squeezed and worn. The limit device is severely worn and squeezed for a long time, resulting in unstable limiting of the limit device and needs to be replaced frequently. The limit device needs to be replaced every 3-4 days during normal use, which wastes materials, time and energy. At the same time, the wear and instability of the limit device will make the limiting unstable, resulting in poor operation of the entire rotary water bath sterilizer, thereby causing safety hazards.
