[0049] like Figure 2-3 As shown, the main frame 1 includes a panel 1-1, and a plurality of lifting bearing seats 1-2 are symmetrically installed around the panel 1-1. A lifting platform screw sleeve 1-7 is installed in the lifting bearing seat 1-2, and the lifting platform screw sleeve 1-7 is threadedly connected to the lifting screw rod 1-3. One end of the lifting screw rod 1-3 passes through the lifting platform screw sleeve 1-7 and is installed with a platform connecting seat 1-4, and the other end passes through the lifting platform screw sleeve 1-7 and is located at the lower position of the panel 1-1. The upper end of the platform connecting seat 1-4 is connected to the transmission mounting frame 2, and the outer periphery of the lifting platform screw sleeve 1-7 located below the panel 1-1 is sleeved with a driven sprocket 1-10, and a driving sprocket 1-12 is installed at the center position of the lower end surface of the panel 1-1, and the driving sprocket 1-12 and the driven sprocket 1-10 are connected together by a chain 1-13. The driving sprocket 1-12 is connected to the motor 1-11, and the motor 1-11 is installed on the lower end surface of the panel 1-1 through the motor mounting seat 1-9. A plurality of symmetrically distributed motor seat cushion columns 1-8 are installed between the motor mounting seat 1-9 and the panel 1-1. A profile frame 1-5 is symmetrically installed around the panel 1-1, and a foot mounting plate 1-6 is installed at the bottom of the profile frame 1-5.

[0050] Specifically, the motor 1-11 (forward and reverse motor) is started, the driving sprocket 1-12 rotates, and then the driven sprocket 1-10 is driven to rotate through the chain 1-13. The rotation of the driven sprocket 1-10 drives the lifting screw 1-3 to rotate. The lifting screw 1-3 moves up and down in the vertical direction under the lifting platform screw sleeve 1-7 (according to the screw principle). When it moves, it drives the transmission mounting frame 2 fixedly connected to it to move up and down, thereby realizing the automatic adjustment of the height position of the feeder.

[0051] like Figure 4-5As shown, the transmission mounting frame 2 includes a bottom plate 2-1, and support plates 2-2 are symmetrically installed in the front and rear directions of the bottom plate 2-1, and the support plates 2-2 are fixedly connected together through a plurality of connecting rods 2-6. An upper support plate 2-3 is installed on the right outer side wall of the support plate 2-2; a push plate rear track seat 2-4 and a push plate front track seat 2-5 are symmetrically installed between the support plates 2-2, and a gap is left between the push plate rear track seat 2-4 and the push plate front track seat 2-5. A lifting plate 2-7 is symmetrically installed between the push plate rear track seat 2-4 / push plate front track seat 2-5, and a number of lifting cylinders 2-8 are symmetrically installed at the bottom of the lifting plate 2-7. The lifting and lowering operation of the lifting plate 2-7 is realized by starting the lifting cylinders 2-8 (all lifting cylinders 2-8 in this process work synchronously. A draw plate 2-10 is provided on the side of the lifting plate 2-7 close to the support plate 2-2, and the draw plate 2-10 is located above the lifting plate 2-7. The draw plate 2-10 can be slid out of the support plate 2-2 and then connected to the draw plate cylinder 2-9. The support plate 2-2 is provided with a through hole for the draw plate 2-10 to move. When the draw plate cylinder 2-9 is started, it drives the support plate 2-2 to move in the front and rear directions. In this embodiment, the front and rear draw plates 2-10 move toward or away from each other under the action of their respective draw plate cylinders 2-9, thereby realizing the opening and closing operation of the draw plate 2-10 and completing the support of the filling mold 4.

[0052] A left-right moving mechanism 2-15 is installed on the outer wall of the upper support plate 2-3, and the left-right moving mechanism 2-15 is connected to the synchronous belt mechanism 2-14, and the synchronous belt mechanism 2-14 is connected to the synchronous belt mechanism 1 2-12 through the transmission shaft 2-13, and the synchronous belt mechanism 1 2-12 is driven by the motor 1 2-11. A through slot 2-16 is provided on the upper support plate 2-3, and a connecting piece connecting the left-right moving mechanism 2-15 and the blister feeding device 6 is slidably installed in the through slot 2-16. Specifically, the motor 1 2-11 (forward and reverse motor) rotates, and the transmission shaft 2-13 is driven to rotate through the synchronous belt mechanism 1 2-12. The rotation of the transmission shaft 2-13 drives the left-right moving mechanism 2-15 to start through the synchronous belt mechanism 2-14, and the right moving mechanism 2-15 drives the blister feeding device 6 to move left and right through the connecting piece.

[0053] The left-right moving mechanism 2-15 includes a lead screw 2-15-1 located in the middle, the lead screw 2-15-1 is threadedly connected to the left-right moving slider 2-15-3, and the left-right moving slider 2-15-3 is slidably mounted with symmetrically distributed limit slide bars 2-15-2, the limit slide bars 2-15-2 are located on both sides of the lead screw 2-15-1, and the lead screw 2-15-1 is fixedly connected to the synchronous belt mechanism 2-14. According to the principle of the lead screw, the lead screw 2-15-3 rotates, and under the action of the limit slide bar 2-15-2, the left-right moving slider 2-15-3 is driven to move left-right, and then the connecting rod fixedly connected to the left-right moving slider 2-15-3 moves left-right, so as to realize the left-right movement of the blister feeding device 6.

[0054] like Figure 6-7 As shown, the push mold device 3 includes a motor 2-4 located at the gap between the push plate rear track seat 2-4 and the push plate front track seat 2-5, and the motor 2-4 is connected to the screw mechanism 1 3-6 and the coupling 3-7 through the synchronous belt mechanism 3-5, and the other end of the coupling 3-7 is connected to the screw mechanism 2-8. The motor 2-4 drives the screw on the screw mechanism 1 3-6 and the coupling 3-7 to rotate through the synchronous belt mechanism 3-5, so that the screw mechanism 1 3-6 and the screw mechanism 2 3-8 move toward or away from each other.

[0055] The lead screw mechanism 1 3-6 and the lead screw mechanism 2 3-8 have the same structure, and both include a lead screw 2 3-6-1 rotatably installed between the push plate rear track seat 2-4 / the push plate front track seat 2-5, the lead screw 2 3-6-1 is threadedly connected to a screw nut block 3-6-2, and two sides of the lead screw 2 3-6-1 are symmetrically installed with a limit slide bar 2 3-6-3 slidably connected to the screw nut block 3-6-2. According to the principle of the lead screw, the screw nut block 3-6-2 moves left and right under the rotation of the lead screw 2 3-6-1 and the limiting action of the limit slide bar 2 3-6-3.

[0056] The left and right nut blocks 3-6-2 are symmetrically installed with several push head fixing plates 3-1 and scraper templates 3-9. Among them, the push head fixing plate 3-1 is installed on the lower end surface of the nut block 3-6-2, and the push head support plate 3-2 is installed at one end of the push head fixing plate 3-1 away from the nut block 3-6-2, and the other end of the push head support plate 3-2 is installed with a push head 3-3, and the push head 3-3 is located above the push plate rear track seat 2-4. When the push head fixing plate 3-1 moves with the nut block 3-6-2, the push head 3-3 also moves accordingly. During the movement, the end of the push head 3-3 pushes the filling mold 4 to move to the right to complete the pushing operation. The scraper template 3-9 is installed on the upper end surface of the nut block 3-6-2, and the scraper template 3-9 can push the filling mold 4 to move to the left as the nut block 3-6-2 moves. In this embodiment, when the pusher head 3-3 moves to the right, the scraper template 3-9 moves to the left; conversely, when the pusher head 3-3 moves to the left, the scraper template 3-9 moves to the right.

[0057] like Figure 8-9 As shown, the filling mold 4 includes a mold body, and the two sides of the mold body are symmetrically integrally formed with limiting support blocks 4-1, which play a supporting and limiting role during the replacement process. A number of protrusions 4-2 are equidistantly installed on the mold body along the X-axis direction, and the protrusions 4-2 are smoothly transitioned to facilitate the medicine to enter the bubble eye of the filling mold more smoothly. A number of partition ribs 4-3 are equidistantly installed between adjacent protrusions 4-2 along the X-axis direction, which is conducive to the medicine entering the bubble eye and improving the filling rate of the medicine. A number of bubble eyes 4-4 are equidistantly opened between adjacent partition ribs 4-3 along the Y-axis direction, which is consistent with the bubble eye shape of the equipment mold.

[0058] like Fig.10 As shown, the roller brush feeder 5 includes a feeder box 5-5, in which a plurality of feeding roller brushes 5-4 are installed at equal intervals, and a drug blocking roller brush 5-3 and a feeding port 5-6 are installed on the left and right sides of the plurality of feeding roller brushes 5-4 respectively; the plurality of feeding roller brushes 5-4 and the drug blocking roller brush 5-3 are driven to rotate by a double-sided toothed synchronous belt pulley set 5-2, and the double-sided toothed synchronous belt pulley set 5-2 is driven by a roller brush feeder motor 5-1. The medicine to be filled is discharged through the feeding port 5-6, and the medicine entering the feeder box 5-5 is filled into the bubble eye 4-4 by the rolling action of the feeding roller brush 5-4, completing the medicine filling operation.

[0059] like Figure 11-12As shown, the bubble cap feeding device 6 includes a screw mounting plate 6-10 fixedly connected to the left-right moving mechanism 2-15, a tracking servo motor 6-1 is installed on the screw mounting frame 6-10 at the front end, and a tracking servo motor mounting plate 6-9 is installed on the end of the tracking servo motor 6-1 away from the screw mounting frame 6-10 at the front end. A guide shaft 6-2 is symmetrically installed between the tracking servo motor mounting plate 6-9 and the screw mounting frame 6-10 at the rear end, and a screw 6-3 is installed at the center position between the guide shafts 6-2. One end of the screw 6-3 passes through the tracking servo motor mounting plate 6-9 and is connected to the tracking servo motor 6-1, and the other end is rotatably installed on the screw mounting frame 6-10 at the rear end. A lateral running slider 6-4 is threadedly connected to the screw 6-3, and the lateral running slider 6-4 is slidably connected to the guide shaft 6-2. By starting the tracking servo motor 6-1, the screw rod 6-3 rotates, and according to the screw principle, under the limiting action of the guide shaft 6-2, the transverse running slider 6-4 moves back and forth on the screw rod 6-3.

[0060] A feeding lifting cylinder 6-6 is installed at the center of the lower end surface of the horizontal running slider 6-4, and a connecting plate 6-7 is installed at the working end of the feeding lifting cylinder 6-6, and a suction cup group 6-8 is installed at the lower end of the connecting plate 6-7. A plurality of guide holes are symmetrically installed on the horizontal running slider 6-4, and a lifting guide shaft 6-5 is slidably installed in the guide hole, and the bottom of the lifting guide shaft 6-5 is connected to the connecting plate 6-7. When the feeding lifting cylinder 6-6 is started, under the limiting action of the lifting guide shaft 6-5, the connecting plate 6-7 drives the suction cup group 6-8 to move up and down.

[0061] The suction cup group 6-8 includes a suction cup mounting plate 6-8-3, a vacuum air pipe joint mounting plate 6-8-4 is mounted on the upper end of the suction cup mounting plate 6-8-3, a suction cup guard plate 6-8-2 is mounted on the lower end of the suction cup guard plate 6-8-2, and a plurality of suction cups 6-8-1 connected to the vacuum air pipe joint mounting plate 6-8-4 are mounted on the lower end surface of the suction cup guard plate 6-8-2, and the plurality of suction cups 6-8-1 are equidistantly distributed. The suction cup 6-8-1 is designed to correspond to the bubble eye 4-4 one to one, and under the action of vacuum, the suction cup group 6-8 performs a drug suction operation on the drug in the filling mold 4.

[0062] Specifically, under the action of the left and right movement of the left and right moving mechanism 2-15 and the front and rear movement of the transverse running slider 6-4, the suction cup group 6-8 is adjusted to move to the position directly above the filling mold 4. At this time, the feeding lifting cylinder 6-6 extends out and acts on the suction cup group 6-8 through vacuum to suck the medicine in the filling mold 4. After the suction is completed, the feeding lifting cylinder 6-6 retracts, the left and right moving mechanism 2-15 is reset, and the blister feeding device 6 returns to its original position.

[0063] The action process of the present invention is as follows:

[0064] First, if Fig.13 As shown, there are six filling molds 4, namely, filling mold 4A, filling mold 4B, filling mold 4C, filling mold 4D, filling mold 4E, and filling mold 4F.
