The friction disc 200 is rigidly connected to the drive shaft 100 in a circumferential direction such that the friction disc 200 rotates in synchronization with the drive shaft 100.

The baffle 500 is disposed on the same side of the wheel 300 as the push washboard 310. The baffle 500 is used for preventing the body of the penicillin bottle or the infusion bottle from moving along with the movement of the push and twist plate 310, that is, a pushing force opposite to the push and twist plate 310 is applied to the penicillin bottle, so that the plastic bottle cap is separated from the body of the penicillin bottle under the condition that the force of the push and twist plate 310 and the baffle 500 is applied together.

The wheel disc 300 is slidably connected to the propeller shaft 100 in the axial direction. The screw locking portion is used to abut against the disc 300, preventing the disc 300 from slipping off the end of the propeller shaft 100. The thread locking portion is also used to change the magnitude of static pressure between the friction disc 200 and the disc 300 by changing how much the thread is engaged with the drive shaft 100, thereby changing the magnitude of static friction between the friction disc 200 and the disc 300.

The fixed shaft 101 and the pickup plate 310 are disposed on the same side of the wheel disc 300, and the axis of the fixed shaft 101 coincides with the axis of the rotation shaft of the wheel disc 300. The stationary shaft 101 is bearing-connected to a bearing housing 102. The drive shaft 100 coincides with the axis of the stationary shaft 101. The friction disc 200 and the disc 300 are engaged with each other so that the friction disc 200 applies a static friction force to the disc 300, thereby driving the disc 300 to rotate. The baffle 500 is disposed on the same side of the wheel 300 as the push washboard 310. The baffle 500 is used for blocking the body of the penicillin bottle or the infusion bottle from moving along with the movement of the push washboard 310. Namely, a pushing force opposite to the pushing and rubbing plate 310 is applied to the penicillin bottle, so that the plastic bottle cap is separated from the bottle body under the condition that the penicillin bottle is jointly applied with the pushing and rubbing plate 310 and the baffle 500.

In one embodiment, as shown in FIG. 22, the bearing housing 102 is fixedly attached to the bezel 500.

In one embodiment, as shown in fig. 22, the drive shaft 100 is a stepped shaft.

For the purpose of facilitating understanding of the present application, the following is a brief description of the method of using the apparatus of the present application, and it should be noted that the following should not be construed as limiting the scope of the present application.

A medical staff holds a penicillin bottle or an infusion bottle by hand and puts the penicillin bottle or the infusion bottle into the bottle mouth insertion hole 510 of the baffle 500 of the opening device; the activation sensor 90 senses that the bottle is emitting an activation signal; the electric control program starts the bottle opening motor 10; the bottle opening motor 10 increases the torque through the reducer 20 and then transmits the torque to the transmission shaft 100; the transmission shaft 100 drives the friction disc 200 fixedly connected with the pre-support to rotate; the wheel disc 300 is driven by the static friction force of the friction disc 200 to rotate synchronously with the friction disc; the pushing and rubbing plate 310 arranged on the wheel disc 300 is in contact with the vial cap of the penicillin bottle or the infusion bottle, and applies a pushing force in an opposite direction to the penicillin bottle or the infusion bottle together with the baffle plate 500, so that the plastic vial cap of the aluminum-plastic combined cap is separated from the vial body, and the aim of opening the penicillin bottle or the infusion bottle is fulfilled. When the marking part 320 arranged on the wheel disc 300 rotates along with the wheel disc 300 for one circle, the marking part is detected by the brake sensor 600, the brake sensor 600 is triggered to send out a brake signal for stopping the torque output of the transmission shaft 100, and the bottle opening motor 10 is turned off by the electronic control program. The plastic cover falls into the recovery box, and the medical staff takes out the penicillin bottle or the infusion bottle which is opened, so that the opening operation of one penicillin bottle or the infusion bottle is completed.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only represent some embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the concept of the present invention, several variations and modifications can be made, which are within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
