DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] Reference Figure 1-5 , a packaging machinery and equipment for pharmaceutical processing, comprising:

[0028] A medicine bag feeding mechanism, the medicine bag feeding mechanism comprises a first conveyor belt 1, a guide slide 11, a conical feeding hopper 2 and a pulling component for pulling the conical feeding hopper 2 for positioning and delivery, a guide slide 11 is provided below the output end of the first conveyor belt 1, the output end of the guide slide 11 is above the conical feeding hopper 2, the conical feeding hopper 2 is installed on the pulling component and the pulling component can pull the conical feeding hopper 2 to move at a fixed distance;

[0029] When the medicine bags fall from the first conveyor belt 1 one by one, the conical feeding hopper 2 has been aligned with an inclined slide cavity 40. When the next medicine bag is detected at the output end of the first conveyor belt 1, the conical feeding hopper starts to move to the top of the next inclined slide cavity 40, and so on. However, when it reaches the position of the last inclined slide cavity 40 and the next medicine bag falls, the first conveyor belt will stop transporting for a few seconds, waiting for the packaging box to reach the position and be corrected. At this time, the grouped medicine bag sleeve will throw out a group of medicine bags, and after the throwing is completed, it will be transported again.

[0030] A medicine bag separation downward pipeline, the medicine bag separation downward pipeline comprises an inclined separation slide 4 and a drooping docking bag throwing separation tube 41, the inclined separation slide 4 is separated into an inclined slide cavity 40 by a plurality of first thin plates, the drooping docking bag throwing separation tube 41 is separated into a drooping slide cavity 411 by a plurality of second thin plates, the inclined separation slide 40 is docked with the drooping docking bag throwing separation tube 41 through a conical slide, a plurality of slide cavities are arranged in the conical slide and are used to dock the inclined slide cavity 40 and the drooping slide cavity 411, the bottom opening of the conical feeding hopper 2 moves back and forth above the top of the inclined separation slide 40, so that the bottom opening of the conical feeding hopper 2 is aligned with the top opening of each inclined slide cavity 40;

[0031] The inclined slideway chamber 40 is inclined to prevent the medicine bag from falling with great impact force and to move downward slowly. The drooping slideway chamber 411 is vertical to facilitate docking with the back.

[0032] A grouped medication bag sleeve, the grouped medication bag sleeve comprises a sleeve tube 5 and a lower medication bag insertion tube 51, the upper half of the sleeve tube 5 is used to be sleeved outside the drooping docking bag separation tube 41, the lower half of the sleeve tube 5 is provided with a docking slide cavity 50, each of the drooping slide cavities 410 is docked with each docking slide cavity 50 after being moved downward, the sleeve tube 5 is provided with a blocking plate assembly at the bottom position to block the bottom of all docking slide cavities 50, a plurality of lower medication bag slide cavities 511 are provided in the lower medication bag insertion tube 51, and the sleeve tube 5 and the lower medication bag insertion tube 51 are docked with a conical slide;

[0033] When the drooping slide cavity 411 is docked with the docking slide cavity 50, the medicine bag will automatically fall into the docking slide cavity 50. When it is full, the blocking plate is pulled out to fall, but the lower medicine bag insertion tube 51 must be moved down and inserted into the packaging box first.

[0034] The packaging and conveying mechanism includes a second conveyor belt 7 and a packaging box correction component. The second conveyor belt 7 conveys packaging boxes. The packaging boxes are corrected when they are conveyed to the packaging box correction component arranged next to the second conveyor belt 7. Then, the lower medicine bag insertion tube 51 moves downward and is inserted into the packaging box.

[0035] When the packaging box moves to this position, the packaging box correction component will correct the position, and then the medicine bag will be put into the packaging box.

[0036] The length of the top opening of the conical feeding hopper 2 is more than twice the length of the top opening of the inclined dividing chute 4. When the bottom opening of the conical feeding hopper 2 is aligned with the inclined chute cavity 40 at the leftmost end of the inclined dividing chute 4, the output end of the guide chute 11 is located above the rightmost end of the top opening of the conical feeding hopper 2.

[0037] When the device is moved to the rightmost side, more than half of the conical feeding hopper 2 is opened for the medicine bag to slide in.

[0038] The bottom opening of the conical feeding hopper 2 is 10-20% smaller than the top opening of each inclined slideway cavity 40, and the distance between the bottom opening of the conical feeding hopper 2 and the top opening of the inclined slideway cavity 40 is 0.5-1.0 cm. The medicine bag slides in without error, and the distance cannot be too far, otherwise, the edge of the medicine bag will be stuck or it will not fall normally.

[0039] The pulling assembly includes two limit slide bars 21, a pull rod 22, a servo motor 3 and a pull screw 31. Two sliding blocks are symmetrically provided on the two side walls of the conical feeding hopper 2. The two sliding blocks are respectively sleeved on the two limit slide bars 21. A pull rod 22 is fixed at the middle position of the rear side wall of the conical feeding hopper 2. A pull screw 31 is connected to the rotating shaft of the servo motor 3. One end of the pull screw 31 is spirally inserted from the end of the pull rod 22.

[0040] The servo motor 3 can pull the pull rod 22 to move at a fixed distance each time, thereby pulling the conical feeding hopper 2 to move at a fixed distance.

[0041] The bottom end of the drooping slideway cavity 411 is narrowed and closed, and the area of ​​the narrowed and closed area is 80-90% of the cross-sectional size of the drooping slideway cavity 411. It is convenient for the docking process and accurate downward movement. The medicine bag is soft and will automatically deform and fall appropriately at the narrowed position.

[0042] The blocking plate assembly includes a blocking plate 6 and two pulling cylinders 61. The blocking plate 6 is inserted from the side wall of the sleeve near the bottom end and moves through all the docking slide cavities 50. Two pulling cylinders 61 are symmetrically arranged on the outer wall of the sleeve 5. The cylinder axes of the pulling cylinders 61 are respectively connected to the two sides of the end of the blocking plate 6 through a connecting rod. The width of the blocking plate 6 is half the length of the docking slide cavity 50 and the blocking plate 6 is located in the middle position of the docking slide cavity 50.

[0043] Each time when all the medicine bags in the docking slide cavity 50 are filled, the grouped medicine bag sleeves are moved downward (the downward movement mechanism does not slide out), and after moving downward, docking is performed, and then the blocking plate 6 is immediately pulled outward to slide out all the medicine bags waiting to fall.

[0044] The lower medicine bag slide cavity 511 extends upward and is connected to the docking slide cavity 50 in a one-to-one correspondence, and the inner diameter of the lower medicine bag slide cavity 511 is the same as that of the docking slide cavity 50.

[0045] To facilitate smooth sliding, the width of the blocking plate 6 is half the length of the docking slideway cavity 50 to ensure that the insertion interface is smaller than the width of the medicine bag and will not be stuck at the card interface position.

[0046] The packaging box correction assembly includes a positioning plate 8 and two limiting plates 9, the rear sides of which are both mounted on a fixed-distance push cylinder. The two limiting plates 9 are symmetrically arranged on both sides of the second conveyor belt 7, and the positioning plate 8 is arranged on the side of one of the limiting plates 9 facing the output direction of the second conveyor belt 7. Figure 4 First, use the positioning plate 8 to position the medicine box. After the medicine box arrives, use two limiting plates 9 to correct it to the middle position, but do not squeeze it, ensuring that the distance between the two limiting plates 9 is 1-2mm larger than the width of the packaging box.

[0047] The outer diameter of the lower medicine bag insertion tube 51 is 5-15% smaller than the inner diameter of the packaging box, which is convenient for insertion. Since the edge of the medicine bag is easy to fold, there will be folds in the lower medicine bag slideway cavity 511, but it will not affect the fall. After falling, the pressed edge of the medicine bag will automatically unfold, fill the medicine box and contact the side wall, just completing the packaging.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
