Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical packaging technology, and in particular to a device for packaging pharmaceutical inner boxes. Background Technology

[0002] In the pharmaceutical packaging system, the drug inner box is a packaging layer between the drug box and the shipping carton. It can accommodate multiple smallest sales units (i.e., drug boxes) to provide secondary physical protection for the drugs inside, and is usually sold as a separate sales unit at the retail stage.

[0003] When packaging medicine boxes (i.e., after multiple smaller medicine boxes have been placed into the medicine box), a packaging device (i.e., a packaging line) is typically used to package the medicine box containing the smaller medicine boxes. However, existing packaging devices for medicine boxes are not very effective at packaging the medicine boxes during the packaging process, which can lead to damage to the medicine boxes. This problem not only directly wastes packaging materials and increases production costs, but also seriously affects overall packaging efficiency due to the need to handle damaged parts and the resulting equipment downtime for maintenance.

[0004] Therefore, ensuring the packaging effect of medicine boxes to avoid damage during the packaging process, thereby avoiding waste of packaging materials and improving overall packaging efficiency, has become an urgent problem to be solved. Utility Model Content

[0055] For those skilled in the art, this invention can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the invention by illustrating examples.

[0056] Medicine box

[0057] like Figure 13 As shown, Figure 13 An exemplary illustration shows the overall structure of a medicine box, which is typically made of rigid cardboard and has a rectangular structure with or substantially thin walls, a closed bottom, and an open top. For example, Figure 13 As shown, two upper flaps 101 are respectively installed on the top of two opposite side walls of the medicine box, and there is a crease between the upper flaps 101 and the medicine box. A top cover 102 is installed on the top of any side wall adjacent to both upper flaps 101, and there is also a crease between the top cover 102 and the medicine box. The cross-sectional area of ​​the top cover 102 is the same as the cross-sectional area of ​​the medicine box, thus allowing it to close at the opening at the top of the medicine box. An outer edge 103 of the top cover is installed at the end of the top cover 102 away from the medicine box. The length of the outer edge 103 is the same as the top cover 102, and there is a crease between the outer edge 103 and the top cover 102.

[0058] It should be understood that after multiple small medicine boxes (not shown in the figure) are placed into the medicine box, firstly, the two upper flaps 101 are folded along the crease between themselves and the medicine box until they are flush with the top of the medicine box. Then, the top cover 102 is folded along the crease between itself and the medicine box until it is flush with the top of the medicine box. At this time, the top cover 102 will press against the top of the upper flaps 101 and close to the top of the medicine box. Finally, the outer edge 103 of the top cover is folded along the crease between itself and the top cover 102 until it fits against the outer wall of the medicine box, thereby completing the packaging of the medicine box. After the medicine box is packaged (i.e., after the above process is completed), the hot melt glue machine 35 can seal the outer edge 103 of the top cover with the outer wall of the medicine box. The hot melt glue machine 35 is prior art known in the art and will not be described in detail here.

[0059] Example

[0060] like Figures 1-12 As shown, this utility model provides a device for packaging medicine boxes. The device includes at least a conveying mechanism, a first upper folding packaging mechanism, a second upper folding packaging mechanism, a top cover packaging mechanism, a top cover outer edge packaging mechanism, and a hot melt adhesive machine 35, wherein:

[0061] like Figure 1 and Figure 4 As shown, the conveying mechanism includes at least a concave conveyor frame 1 and a conveyor belt 2 located inside it for conveying medicine boxes. Specifically, the conveying mechanism includes at least a conveyor belt 2 and a concave (i.e., a concave cross-section along the vertical direction) conveyor frame 1. The conveyor belt 2 is located inside the conveyor frame 1, and the medicine boxes are configured to be placed on the conveyor belt 2 inside the conveyor frame 1 (not shown in the figure). The conveyor belt 2 is used to convey the medicine boxes placed inside the conveyor frame 1 and on the conveyor belt 2.

[0062] In this embodiment, with Figure 1 For example, the rotation direction of conveyor belt 2 (that is, the conveying direction of conveyor belt 2) is: Figure 1 From the upper left end to the lower right end of the middle conveyor frame 1 (i.e. Figure 1 (clockwise direction in the middle), therefore the conveying direction of the medicine box is also... Figure 1 From the upper left end to the lower right end of the middle conveyor frame 1.

[0063] In this embodiment, the width of the concave conveyor frame 1 is approximately the same as the width of the medicine box (i.e., the inner wall of the conveyor frame 1 will have a clearance fit with the outer wall of the medicine box, with a clearance of 0.5mm-1mm). Therefore, when the medicine box is placed inside the conveyor frame 1 for conveying, the inner wall of the conveyor frame 1 will limit the conveying of the medicine box. Specifically, when the medicine box is placed on the conveyor belt 2 inside the conveyor frame 1, the top of the medicine box will be higher than the top of the conveyor frame 1; for example, the top of the conveyor frame 1 will be located at approximately two-thirds of the height of the medicine box.

[0064] like Figure 1 As shown, the first upper folding packaging mechanism, the second upper folding packaging mechanism, the top cover packaging mechanism, the top cover outer edge packaging mechanism, and the hot melt glue machine 35 are all installed on the conveyor frame 1 and along the conveying direction of the medicine box (i.e., Figure 1 The middle conveyor frame 1 is set sequentially from the upper left end to the lower right end.

[0065] It should be understood that this device can be a standalone device, that is, a device for automatically packaging medicine boxes independently. Furthermore, this device can also be part of a pharmaceutical production line (known in the art) (i.e., a packaging line within a pharmaceutical production line), which will not be elaborated upon here.

[0066] like Figure 1 As shown, the first upper folding packaging mechanism includes at least a rotating plate 11, and the second upper folding packaging mechanism includes at least a pressure plate 18. The rotating plate 11 and the pressure plate 18 are used to squeeze the upper folds 101 on both sides of the medicine box during transportation, so as to package the upper folds 101 on both sides of the medicine box.

[0067] In this embodiment, as Figure 1 , Figure 4 , Figure 8 and Figure 9 As shown, the pressure plate 18 can be a long strip-shaped plate structure, and the end of the pressure plate 18 closest to the rotating plate 11 (i.e., Figure 1 The upper left end of the pressure plate 18 is inclined, and its inclined edge is located at the bottom end of the pressure plate 18. The bottom end of the pressure plate 18 is preferably parallel to the top end of the conveyor belt 2.

[0068] like Figure 1 As shown, the top cover packaging mechanism includes at least a pressure bar 27, which is used to squeeze the top cover 102 of the medicine box during transport to package the top cover 102 of the medicine box.

[0069] In this embodiment, as Figure 1 , Figure 4 and Figure 10 As shown, the compression member 27 can be a two-section bent structure, so as to... Figure 1For example, the left end of the pressure bar 27 is an inclined structure, and the right end of the pressure bar 27 is a horizontal structure. For ease of description, the inclined part of the pressure bar 27 is named the inclined pressure bar, and the horizontal part of the pressure bar 27 is named the horizontal pressure bar. The inclined pressure bar... Figure 1 The left end of the middle is higher than the inclined compression bar. Figure 1 The right end of the horizontal pressure bar, i.e., the end of the pressure plate 18 near the rotating plate 11, has the same inclination direction as the inclined pressure bar. The bottom end of the horizontal pressure bar is preferably parallel to the top end of the conveyor belt 2. The inclined pressure bar is located above the pressure plate 18, and the pressure plate 18 is... Figure 1 There is a certain distance between the right end of the horizontal pressure bar and the inclined pressure bar. The horizontal pressure bar is located at the end of the pressure plate 18 away from the rotating plate 11 (i.e., at the end of the pressure plate 18). Figure 1 (The right end of the middle).

[0070] like Figure 1 , Figure 3 , Figure 4 , Figure 11 and Figure 12 As shown, the outer edge packaging mechanism of the upper cover includes at least a pressure tongue 32. The end of the pressure tongue 32 away from the hot melt glue machine 35 has an arc-shaped structure. The pressure tongue 32 is used to squeeze the outer edge 103 of the upper cover of the medicine box being transported, so as to package the outer edge 103 of the upper cover of the medicine box.

[0071] After passing through the aforementioned mechanisms, the medicine box will be packaged. Then, the hot melt glue machine 35 can be used to seal the packaged medicine box, that is, to seal the outer edge 103 of the top cover with the outer side wall of the medicine box.

[0072] Furthermore, since the end of the depressor 32 furthest from the hot melt glue machine 35 is arc-shaped, when the outer edge 103 of the upper cover of the medicine box is squeezed, its arc can be used to press down the outer edge 103 of the upper cover in advance. That is, when the outer edge 103 of the upper cover enters the rear end of the depressor 32, it is already at a low position and basically fits the outer wall of the medicine box. Therefore, the outer edge 103 of the upper cover will not be damaged, avoiding waste of packaging materials and improving the packaging yield and overall packaging efficiency.

[0073] Specifically, such as Figure 1 and Figure 4 As shown, the conveying mechanism also includes at least two drive rollers 3 respectively driven at both ends of the conveyor belt 2, preferably two drive rollers 3. A power motor (not shown in the figure and known in the art) is installed on the conveyor frame 1, and the output end of the power motor is driven by any one of the drive rollers 3, thereby driving the conveyor belt 2 to rotate and conveying the medicine boxes inside the conveyor frame 1.

[0074] In this embodiment, the output end of the power motor (i.e., its rotating shaft) can be coaxially arranged with any of the transmission rollers 3, and the output end of the power motor can be coaxially connected with any of the transmission rollers 3 through a coupling known in the art, thereby realizing the transmission cooperation between the two.

[0075] Since the rotation direction of conveyor belt 2 (that is, the conveying direction of conveyor belt 2) is Figure 1 From the upper left end to the lower right end of the middle conveyor frame 1 (i.e. Figure 1 (clockwise direction in the middle), therefore the rotation direction of the transmission roller 3 is also clockwise. Figure 1 The clockwise direction in the middle.

[0076] Specifically, such as Figure 2 , Figure 6 and Figure 7 As shown, the first upper folding packaging mechanism also includes a lifting frame 4 installed on the outer wall of the conveyor frame 1. A servo motor 7 is slidably mounted on the lifting frame 4 in a vertical direction. A rotating plate 11 is mounted on the output end of the servo motor 7 (i.e., on the output shaft of the servo motor 7), and the rotating plate 11 is located above the conveyor frame 1. A lead screw 8 is slidably mounted on the lifting frame 4 in a vertical direction (i.e., in a direction parallel to the direction in which the servo motor 7 is slidably mounted on the lifting frame 4). The lead screw 8 is threadedly engaged with the servo motor 7.

[0077] In this embodiment, the lifting frame 4 can be a cuboid structure, the rotating plate 11 can be roughly shaped like the Arabic numeral "6", and the rotating plate 11 is perpendicular to the output end of the servo motor 7. Wherein, as Figure 6 As shown, the rotating plate 11 and the output end of the servo motor 7 can be connected by bolts known in the art, and no particular limitation is made here.

[0078] More specifically, such as Figure 6 As shown, a lifting hole 5 is provided on the lifting frame 4 along the vertical direction (i.e., the direction parallel to the lead screw 8). A lifting block 6 is installed on the outer wall of the servo motor 7. The lifting block 6 is located inside the lifting hole 5 and is limited and slidably engaged with the inner wall of the lifting hole 5. That is, the servo motor 7 is limited and slidably connected to the lifting frame 4 through the lifting hole 5 and the lifting block 6. The lead screw 8 is located inside the lifting hole 5 and is limited and rotatably connected with the inner wall of the bottom end of the lifting hole 5. The lead screw 8 is threadedly engaged with the lifting block 6. That is, the servo motor 7 is threadedly engaged with the lead screw 8 through the lifting block 6.

[0079] In this embodiment, as Figure 2 , Figure 6 and Figure 7 As shown, the lifting hole 5 can be a cuboid structure. Since the outer wall of the lifting block 6 slides with the inner wall of the lifting hole 5, the lifting block 6 can be a cuboid structure with the same width as the lifting hole 5. The height (thickness) of the lifting block 6 is much smaller than the height (length) of the lifting hole 5.

[0080] In this embodiment, a tapered roller bearing (not shown in the figure and known in the art) can be installed on the inner wall of the bottom end of the lifting hole 5. The outer ring of the tapered roller bearing is connected to the lifting frame 4, and the inner ring of the tapered roller bearing is coaxially arranged with the lead screw 8 and connected to the bottom end of the lead screw 8, thereby realizing the limiting rotational connection between the lead screw 8 and the inner wall of the bottom end of the lifting hole 5.

[0081] In this embodiment, a threaded hole for the lifting block 6 can be provided in the vertical direction, and the threaded hole for the lifting block is adapted to the external thread of the lead screw 8 and is coaxially arranged with the lead screw 8. The lead screw 8 is located in the threaded hole for the lifting block and is threadedly engaged with the threaded hole for the lifting block, thereby realizing the threaded engagement between the lead screw 8 and the lifting block 6.

[0082] When packaging different medicine boxes, since the heights of the boxes may vary, the height of the rotating plate 11 needs to be adjusted. This is done by rotating the lead screw 8, causing the lifting block 6 to rise and fall along the lead screw 8. Simultaneously, because the lifting hole 5 limits the movement of the lifting block 6, it does not rotate but only moves within the lifting hole 5. This movement of the lifting block 6 synchronously drives the servo motor 7 and the rotating plate 11, thus adjusting the height of the rotating plate 11.

[0083] Furthermore, such as Figure 2 and Figure 6 As shown, the top of the lifting frame 4 has an open structure, and the top of the lifting hole 5 can communicate with the outside of the lifting frame 4 through the open structure at the top of the lifting frame 4, that is, the lifting frame 4 will have a roughly concave structure. A support plate 9 is detachably installed at the open structure at the top of the lifting frame 4, and the top of the lead screw 8 passes through the support plate 9 and is rotatably connected to the support plate 9. A knob 10 is coaxially installed at the top of the lead screw 8, located at the end of the support plate 9 away from the lifting frame 4, and the bottom end of the knob 10 can slide and engage with the top end of the support plate 9.

[0084] In this embodiment, as Figure 6 As shown, two bolts can be installed on the support plate 9, thereby enabling a detachable connection between the support plate 9 and the top of the lifting frame 4. Preferably, the support plate 9 has a flat rectangular parallelepiped structure.

[0085] In this embodiment, the support plate 9 may have a lead screw through hole that is adapted to the lead screw 8 and coaxial with the lead screw 8, and the diameter of the lead screw through hole is equal to the maximum diameter of the external thread of the lead screw 8, thereby realizing the limiting rotation connection between the lead screw 8 and the support plate 9.

[0086] The support plate 9 provides a limiting effect on the top of the lead screw 8, making the lead screw 8 more stable during rotation. The knob 10 makes it easier to rotate the lead screw 8.

[0087] Furthermore, such as Figure 2 , Figure 6 and Figure 7 As shown, there can be two lifting frames 4, and the two lifting frames 4 are arranged sequentially along the length of the conveyor frame 1. Similarly, there can also be two lifting blocks 6, which are sequentially installed on the two opposite outer walls of the servo motor 7. The two lifting blocks 6 are sequentially and slidably fitted into the lifting holes 5 on the two lifting frames 4. The lead screw 8 can be rotatably installed at the bottom end of any one of the lifting holes 5, for example, it can be... Figure 2 The lifting hole 5 is located on the right side. By setting up two lifting frames 4, the stability of the servo motor 7 on the lifting frame 4 can be improved.

[0088] Specifically, such as Figure 1 , Figure 8 and Figure 9 As shown, the second upper folding packaging mechanism also includes a first mounting plate 12. A first adjusting oblong hole 14 is provided on the first mounting plate 12 along the vertical direction. A first mounting bolt 13 is disposed within the first adjusting oblong hole 14. The first mounting plate 12 is mounted on the outer wall of the conveyor frame 1 via the first mounting bolt 13, i.e., the first mounting bolt 13 is threadedly connected to the outer wall of the conveyor frame 1. A second mounting plate 15 is mounted on the top of the first mounting plate 12, and a pressure plate 18 is mounted on the end of the second mounting plate 15 away from the first mounting plate 12. The pressure plate 18 is located above the conveyor frame 1.

[0089] When packaging different medicine boxes, the height of the pressure plate 18 needs to be adjusted because the boxes may vary in height. Loosening the first mounting bolt 13 allows for vertical adjustment of the pressure plate 18 via the first adjusting oblong hole 14, aligning the bottom of the pressure plate 18 with the bottom of the rotating plate 11. After adjustment, retightening the first mounting bolt 13 fixes the first mounting plate 12 to the outer wall of the conveyor frame 1, thus re-fixing the pressure plate 18.

[0090] Furthermore, such as Figure 1 , Figure 4 , Figure 8 and Figure 9As shown, a second adjusting oblong hole 17 is provided on the second mounting plate 15 along the horizontal direction. A second mounting bolt 16 is provided in the second adjusting oblong hole 17. The second mounting plate 15 is mounted on the top of the first mounting plate 12 by the second mounting bolt 16, that is, the second mounting bolt 16 is threadedly connected to the top of the first mounting plate 12. Preferably, the second mounting plate 15 is perpendicular to the first mounting plate 12.

[0091] In this embodiment, as Figure 8 As shown, there can be two second adjusting oblong holes 17, which are arranged symmetrically and parallel to the center line of the second mounting plate 15. Since the second adjusting oblong holes 17 are provided with second mounting bolts 16, there can also be two second mounting bolts 16. By setting two second adjusting oblong holes 17 and two second mounting bolts 16, the connection stability of the first mounting plate 12 and the second mounting plate 15 can be further improved.

[0092] By using the second adjusting oblong hole 17 and the second mounting bolt 16, the horizontal position of the second mounting plate 15 can be adjusted through the second adjusting oblong hole 17, which in turn allows for the adjustment of the horizontal position of the pressure plate 18.

[0093] Furthermore, such as Figure 9 As shown, an adjustment oval elongated hole 19 is provided on the pressure plate 18 along its length direction. A pressure plate mounting bolt 20 is provided in the adjustment oval elongated hole 19. The pressure plate 18 is mounted on the second mounting plate 15 by the pressure plate mounting bolt 20. That is, the pressure plate mounting bolt 20 is threadedly connected to the side wall of the second mounting plate 15, and preferably the pressure plate 18 is perpendicular to the second mounting plate 15.

[0094] In this embodiment, the number of pressure plate mounting bolts 20 disposed within the adjusting oblong hole 19 can be two or more, preferably two, thereby improving the connection stability between the pressure plate 18 and the second mounting plate 15. By adjusting the arrangement of the oblong hole 19 and the pressure plate mounting bolts 20, the horizontal position of the pressure plate 18 along its length direction can be adjusted by adjusting the oblong hole 19.

[0095] Specifically, such as Figure 4 , Figure 5 and Figure 10 As shown, the upper cover packaging mechanism also includes a third mounting plate 21. The third mounting plate 21 has a third adjusting oval hole 23 along the vertical direction. A third mounting bolt 22 is provided in the third adjusting oval hole 23. The third mounting plate 21 is mounted on the outer wall of the conveyor frame 1 by the third mounting bolt 22, that is, the third mounting bolt 22 is threadedly connected to the outer wall of the conveyor frame 1.

[0096] By adjusting the third oblong hole 23, the height of the third mounting plate 21 in the vertical direction can be adjusted, which in turn can adjust the height of the pressure rod 27 in the vertical direction to accommodate medicine boxes of different heights.

[0097] Furthermore, such as Figure 10 As shown, a fourth mounting plate 24 is provided at the top of the third mounting plate 21. A fourth adjusting oblong hole 26 is provided on the fourth mounting plate 24 along the horizontal direction. A fourth mounting bolt 25 is provided inside the fourth adjusting oblong hole 26. The fourth mounting plate 24 is mounted on the top of the third mounting plate 21 by the fourth mounting bolt 25, i.e., the fourth mounting bolt 25 is threadedly engaged with the top of the third mounting plate 21. Preferably, the fourth mounting plate 24 is perpendicular to the third mounting plate 21. The pressure rod 27 is installed at the end of the fourth mounting plate 24 away from the third mounting plate 21.

[0098] In this embodiment, there can be two fourth adjusting oblong holes 26, arranged symmetrically and parallel to each other along the center line of the fourth mounting plate 24. Since a fourth mounting bolt 25 is provided within each fourth adjusting oblong hole 26, there are also two fourth mounting bolts 25. The arrangement of two fourth adjusting oblong holes 26 and two fourth mounting bolts 25 further improves the connection stability between the fourth mounting plate 24 and the third mounting plate 21.

[0099] By using the fourth adjusting oblong hole 26 and the fourth mounting bolt 25, the horizontal position of the fourth mounting plate 24 can be adjusted through the fourth adjusting oblong hole 26, which in turn can adjust the horizontal position of the pressure rod 27.

[0100] Specifically, such as Figure 1 , Figure 3 , Figure 11 and Figure 12 As shown, the outer edge packaging mechanism of the upper cover also includes a connecting plate 28 mounted on the conveyor frame 1. A fifth mounting plate 29 is mounted on the connecting plate 28, and a pressure tongue 32 is mounted on the end of the fifth mounting plate 29 away from the connecting plate 28. The outer wall of the pressure tongue 32 near the conveyor frame 1 is flush with the inner wall of the conveyor frame 1 near the pressure tongue 32, thereby squeezing the outer edge 103 of the upper cover of the medicine box and packaging the outer edge 103 of the upper cover of the medicine box.

[0101] Furthermore, such as Figure 3 and Figure 11 As shown, a fifth adjusting oblong hole 31 is provided on the fifth mounting plate 29 along the vertical direction. A fifth mounting bolt 30 is provided in the fifth adjusting oblong hole 31. The fifth mounting plate 29 is mounted on the connecting plate 28 by the fifth mounting bolt 30, that is, the fifth mounting bolt 30 is threadedly connected to the connecting plate 28.

[0102] In this embodiment, as Figure 3 and Figure 11 As shown, there can be two fifth adjusting oblong holes 31, which can be arranged symmetrically and parallel to each other along the center line of the connecting plate 28. Since a fifth mounting bolt 30 is installed inside each fifth adjusting oblong hole 31, there are also two fifth mounting bolts 30. The arrangement of two fifth adjusting oblong holes 31 and two fifth mounting bolts 30 further improves the connection stability between the connecting plate 28 and the fifth mounting plate 29.

[0103] In this embodiment, as Figure 3 As shown, the end of the pressure tongue 32 furthest from the hot melt glue machine 35 is the end of the pressure tongue 32 furthest from the fifth mounting plate 29. Therefore, the arc-shaped structure on the pressure tongue 32 is located at the end of the pressure tongue 32 furthest from the fifth mounting plate 29 (i.e., Figure 3 (Left end of the middle pressure tongue 32).

[0104] Furthermore, such as Figure 11 As shown, the end of the pressure tongue 32 near the fifth mounting plate 29 has a horizontally oriented adjustment oblong hole 34. A hand-tightening bolt 33 is installed in the adjustment oblong hole 34, and the pressure tongue 32 is mounted on the fifth mounting plate 29 by the hand-tightening bolt 33, that is, the hand-tightening bolt 33 is threadedly connected to the fifth mounting plate 29. Preferably, there is one hand-tightening bolt 33.

[0105] The horizontal position of the pressure tongue 32 can be adjusted by adjusting the oblong hole 34. Simultaneously, since there is preferably only one hand-tightening bolt 33, the angle of the pressure tongue 32 can be adjusted, allowing it to rotate around the hand-tightening bolt 33. This better accommodates medicine boxes of different heights, ensuring smooth packaging operations.

[0106] In addition, since the hand-tightening bolt 33 is easier to disassemble and assemble than ordinary bolts, the horizontal position and angle of the pressure tongue 32 can be adjusted more conveniently by the setting of the hand-tightening bolt 33.

[0107] Work process

[0108] The working process of this device will be briefly described below in conjunction with the above implementation scheme:

[0109] First, before commencing the actual packaging of the medicine box, the positions of the rotating plate 11, pressure plate 18, pressure rod 27, and pressure tongue 32 need to be adjusted according to the actual height of the medicine box. The adjustment steps are as follows:

[0110] Step 1: Adjust the position of the rotating plate 11: Turn the knob 10, and the lead screw 8 will rotate synchronously, thereby adjusting the height of the servo motor 7 and the rotating plate 11, and adjusting the bottom of the rotating plate 11 to be level with the height of the medicine box.

[0111] Step 2: Adjust the position of the pressure plate 18: Loosen the first mounting bolt 13, the second mounting bolt 16, and the pressure plate mounting bolt 20. This allows adjustment of the position of the pressure plate 18 in the XYZ directions (i.e., horizontal and vertical positions). Specifically, the bottom of the pressure plate 18 should be adjusted to be flush with the height of the medicine box.

[0112] At the same time, the position of the pressure plate 18 needs to be adjusted horizontally so that when the rotating plate 11 rotates to the position closest to the pressure plate 18 (i.e., when the rotating plate 11 rotates to the position closest to the pressure plate 18), the pressure plate 18 is at the same level as the pressure plate 18. Figure 8 When the leftmost and closest position is reached, it is necessary to ensure that the rotating plate 11 does not come into contact with the pressure plate 18, and there is a very small gap between them (similar to the clearance fit known in the art), the gap amount can be about 0.5cm-1cm.

[0113] Step 3: Adjust the position of the pressure rod 27: Loosen the third mounting bolt 22 and the fourth mounting bolt 25 to adjust the horizontal and vertical positions of the pressure rod 27. Specifically, the horizontal end of the pressure rod 27 (i.e., the aforementioned horizontal pressure rod) should be adjusted to be level with the height of the medicine box.

[0114] Step 4: Adjust the position of the pressure tongue 32: Loosen the fifth mounting bolt 30 and the hand-tightening bolt 33 to adjust the horizontal, vertical, and angle positions of the pressure tongue 32. Specifically, the lowest point of the pressure tongue 32 should be adjusted to be below the outer edge 103 of the top cover of the medicine box.

[0115] Then, the actual packaging of the medicine into individual boxes can begin. The following is an example of the entire process of packaging a single medicine box, with the following steps:

[0116] Step 1: Place the medicine box at the entrance of conveyor rack 1 (i.e., Figure 1 The medicine box is placed on the conveyor belt 2 at the upper left end of the middle conveyor frame 1, and the power motor and servo motor 7 are started. At this time, both the conveyor belt 2 and the rotating plate 11 will rotate, thereby conveying the medicine box. The medicine box will be conveyed to the position of the pressure plate 18, and then the upper fold 101 of the medicine box near the pressure plate 18 will be squeezed and packaged.

[0117] In step one, it should be understood that when the upper flap 101 of the medicine box at the end away from the pressure plate 18 is just conveyed to the pressure plate 18... Figure 1When the upper left end of the middle is reached, the rotating plate 11 will rotate to the position closest to the pressure plate 18. That is, the end of the rotating plate 11 will squeeze and package the upper flap 101 of the medicine box away from the pressure plate 18, thereby realizing the squeeze packaging of the two upper flaps 101.

[0118] Step 2: The two compressed and packaged upper flaps 101 will continuously slide against the bottom of the pressure plate 18 during the transport of the medicine box. At this time, the upper cover 102 of the medicine box will be compressed and packaged under the action of the inclined end of the pressure rod 27 (i.e., the inclined pressure rod mentioned above), and the packaging of the upper cover 102 will be completed when it enters the horizontal pressure rod.

[0119] In step two, it should be understood that, as Figure 1 As shown, the inclined compression bar and Figure 1 There is a certain distance between the lower right end of the middle pressure plate 18 and the upper cover 102, so it will pass through this distance without touching the pressure plate 18. At the same time, since the two upper flaps 101 of the medicine box are continuously squeezed by the bottom end of the pressure plate 18 for a period of time during the transport of the medicine box, and there is a crease between the upper flaps 101 and the medicine box, when the upper flaps 101 are separated from the pressure plate 18, that is, when they enter between the horizontal pressure bar and the pressure plate 18, the upper flaps 101 will still maintain the packaged state (i.e., the horizontal state).

[0120] Step 3: The medicine box will be conveyed by conveyor belt 2 to the bottom of the horizontal pressure bar. When it passes the pressure tongue 32, the arc-shaped structure of the pressure tongue 32 will squeeze and package the outer edge 103 of the upper cover of the medicine box, making the outer edge 103 of the upper cover fit against the outer wall of the medicine box. After fitting, the outer edge 103 of the upper cover will continue to be squeezed on the side wall of the pressure tongue 32 for a period of time, thereby keeping the outer edge 103 of the upper cover in contact with the outer wall of the medicine box.

[0121] Step 4: The medicine box from Step 3 will enter the hot melt glue machine 35 and be sealed with glue. After sealing, the medicine box will exit from the outlet of the conveyor frame 1 (i.e., Figure 1 (At the lower right end of the middle conveyor 1), the packaging of the medicine box can be completed.

[0122] It should be understood that the above embodiments or implementation schemes of this utility model can be combined with each other and have corresponding technical effects.
