Example two
The present embodiments provide a filling machine. The filling machine provided in this embodiment differs from the first embodiment in that the controller 6 is designed differently. The controller 6 comprises a driving cylinder, a spindle encoder and a microprocessor. The output shaft of the driving cylinder is connected to the connecting block 532 of the detent mechanism 5, that is, the driving cylinder can drive the detent mechanism 5 to switch between the extended state and the retracted state. The spindle encoder is used for sensing the rotation angle of the middle shaft 32 and is connected with the microprocessor. The microprocessor is also connected with the driving cylinder. When the spindle encoder senses that the center shaft 32 rotates to align one of the stoppers 4 with the corresponding retainer 5, the microprocessor controls the output shaft of the driving cylinder to extend to drive the telescopic head 55 of the retainer 5 to be inserted into the corresponding stopper 4. When the middle shaft 32 needs to continue rotating, the microprocessor controls the output shaft of the driving cylinder to retract so as to drive the telescopic head 55 of the position clamping device 5 to withdraw from the corresponding position limiting device 4. Therefore, the filling machine can effectively solve the problem that the rotating wheel 11 is not accurately positioned, and meanwhile, the rotation of the rotating wheel 11 at other positions cannot be interfered, so that the improvement of the capacity of the filling machine is facilitated, and the stop frequency is greatly reduced.
While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
