Referring to fig. 9, according to a second embodiment of the present application, the difference from the first embodiment is that a dispensing tray 11 and a fixing frame 12 are further disposed below the cutting mechanism 8, the fixing frame 12 is disposed in the dispensing tray 11, a fixing frame 12 is disposed directly below the plastic film core 3 during the bag making process, the medicine bag is driven by the film driving mechanism 6 to extend into the fixing frame 12, and the cutting mechanism 8 separates the medicine bag from the bag making film 10 above after the medicine bag extends into the fixing frame 12 by a predetermined depth, and the upper opening of the medicine bag is opened. The fixing frame 12 and the dispensing tray 11 are used for transferring the medicine bag to the dispensing station, and the fixing frame 12 needs to have the functions of positioning the medicine bag and positioning the shape, so that the medicine bag needs to be abutted against the inner wall of the fixing frame 12, and the self gravity of the medicine bag alone cannot overcome the friction force between the medicine bag and the fixing frame 12 due to the lighter weight of the medicine bag, and automatically enters the preset position of the fixing frame 12. With the structure, in the bag making process, after the side edges and the bottom of the medicine bag are sealed, the medicine bag is stretched into the fixing frame 12 by utilizing the integral transmission force of the film driving mechanism 6 to the bag making film 10, and finally the medicine bag is cut off and separated from the upper bag making film 10, and the cut-off medicine bag keeps open under the action of the four edges of the medicine bag and the inner wall of the fixing frame 12, so that the follow-up medicine dispensing can be completely carried out in the medicine bag without any additional means and structure for expanding the medicine bag.
The working principle of the application is described in detail below:
the rolled bag-making film 10 is stored in the film storage mechanism 1, and can be discharged in a rotating manner under the traction of the bag-making film 10. The bag making film 10 enters the first plastic film part 2 under the guiding action of the guide roller, two edges of the bag making film 10 enter the guide surface 21, and the bag making film moves against the guide surface 21 under the limiting action of the limiting strip 23, changes from a flat sheet shape into a ring shape, and is wrapped on the strip-shaped plastic film core 3.
Then, the bag-making film 10 enters the second plastic film piece 4 and further sticks to the plastic film core 3 under the gathering action of the outer guiding inclined surface 411 of the annular guiding piece 41, and the bag-making film 10 starts to imitate the shape of the plastic film core 3 to form four edges. The edges of the bag-making film 10 start to overlap under the guiding action of the side seal guiding inclined plane 412 to form side seal parts, and the side seal parts are conveyed downwards through the side seal opening 42.
The bag making film 10 after leaving the second plastic film piece 4 enters a third plastic film piece 9, and the third plastic film piece 9 is also arranged around the plastic film core 3, so that the bag making film 10 can be abutted with four corners of the plastic film core 3 to strengthen four edges which are finally formed;
after the third plastic film member 9 is formed again, the bag-making film 10 enters the side sealing mechanism 5, and here, the side sealing block 51 extends to the side sealing part of the bag-making film 10, and cooperates with the side second forming plate 92 to seal the side sealing part.
After passing through the side sealing mechanism 5, the bag making film 10 needs to enter the bottom sealing mechanism 7 to finish the bottom sealing process of the medicine bag. Here, the first motor 77 of the symmetrical driving mechanism drives the crank 76 to rotate, and then drives the connecting piece 75 to rotate around the hinge shaft thereof, so as to drive the fisheye bearing 74 to move, and the fisheye bearing 74 drives the sliding block 73 on the guide rail 72 to synchronously move. The bottom sealing block 71 provided on the slider 73 seals the bottom of the bag-making film 10.
Taking the second embodiment as an example, the bag making film 10 which completes the bottom sealing process continues to move downwards under the drive of the film driving mechanism 6 and enters the fixing frame 12 right below the bag making film, the fixing frame 12 is provided with a specially designed oval positioning part, the oval positioning part is in contact with four edges of the medicine bag, the medicine bag keeps a trend of opening in the process that the bag making film 10 enters the fixing frame 12, after the bag making film 10 descends to a preset position, the sliding blocks 73 of the symmetrical driving mechanism are close to each other again, the scissors 81 shear the medicine bag and the bag making film 10 on the upper part, meanwhile, the bag making film 10 above completes the bottom sealing process, the batching disc 11 is waited for rotating for a preset angle, the other fixing frame 12 is aligned with the bottom sealing mechanism, and the manufacture of the medicine bag is continued.
While the foregoing is directed to the preferred embodiments of the present invention, it will be appreciated by those skilled in the art that changes and modifications may be made without departing from the principles of the invention, such changes and modifications are also intended to be within the scope of the invention.
