Description

Technical Field

[0001] This invention relates to the field of cartoning machine technology, and in particular to an automatic cartoning machine. Background Technology

[0002] Cartoning machines are widely used in modern pharmaceutical production and manufacturing, serving as a crucial component for the automation and standardization of pharmaceutical production. A cartoning machine includes a clamping conveyor belt, a pushing device, a detection unit, and a sealing device. Packaging boxes are transported via the clamping conveyor belt, which delivers the boxes of medicines to be packaged. Then, the pushing device accurately pushes the medicines to be packaged into the boxes (e.g., pushing instructions and blister packs into the medicine box). The filled boxes are then sealed by the sealing device and inspected by the detection unit. However, existing cartoning machines with clamping conveyor lines have structural defects. They are only suitable for conveying packaging boxes of a certain fixed shape and cannot automatically adjust the clamping size according to the size of the packaging box. This results in poor flexibility and limited applicability, making them unsuitable for packaging boxes of different sizes. Summary of the Invention

[0003] One of the technical problems solved by this invention is to provide an automatic cartoning machine that can circulate and transport packaging boxes between different conveying stations on its clamping conveyor line and can automatically adjust the size of the clamping packaging boxes according to the size of the packaging boxes, so as to be suitable for conveying packaging boxes of different sizes on its clamping conveyor line, thereby improving the applicability of the cartoning machine.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] Automatic cartoning machines include:

[0006] frame;

[0007] At least one clamping conveyor line includes a support, a first clamping device, and a second clamping device;

[0008] The support is disposed on the frame and arranged along the conveying direction of the conveyor line, and multiple conveying stations are arranged on the support along the conveying direction of the conveyor line;

[0009] The first clamping device includes a first driving device and a plurality of first clamping members. Each first clamping member is movably disposed on the frame along the direction in which the packaging box is conveyed and can extend and retract along a direction perpendicular to the support. The first driving device is disposed on the frame and is used to drive each first clamping member to extend, retract and move synchronously. A first clamping space is formed between each pair of adjacent first clamping members. Each first clamping space is used to clamp the packaging box placed on each of the conveying stations.

[0010] The second clamping device includes a second driving device and a plurality of second clamping members. Each second clamping member is movably disposed on the frame along the conveying direction of the conveyor line and can extend and retract in a direction perpendicular to the support. The second driving device is disposed on the frame and is used to drive each second clamping member to extend and retract, each second clamping member to move within each first clamping space, and each second clamping member to move synchronously with each first clamping member, so as to adjust the size of each first clamping space.

[0011] Furthermore, the support includes a first support bar and a second support bar arranged in parallel at intervals. The first support bar is fixed on the frame along the conveying direction of the conveyor line. A movable bracket is also provided on the frame. The second support bar is fixed on the movable bracket along the conveying direction of the conveyor line and is located in the same plane as the first support bar. A plurality of first clamping members are arranged along the conveying direction of the conveyor line and are respectively spaced outside the first support bar and the second support bar. The movable bracket is movably arranged on the frame so that the second support bar can move toward or away from the first support bar.

[0012] Furthermore, the extension and retraction directions of each of the second clamping members are the same as or perpendicular to those of each of the first clamping members.

[0013] Furthermore, the present invention also includes a fourth driving device, which is disposed on the frame and is used to drive the movable support to move toward or away from the first support bar.

[0014] Furthermore, the first driving device includes a first telescopic device, which is disposed on the frame and is used to drive each of the first clamping members to extend and retract along a vertical direction perpendicular to the support.

[0015] Furthermore, the first driving device also includes a first power device, which is mounted on the frame and is used to drive each of the first clamping members to move back and forth synchronously along the conveying direction of the conveyor line.

[0016] Furthermore, the second driving device includes a second telescopic device, which is disposed on the frame and is used to drive each of the second clamping members to extend and retract along a vertical direction perpendicular to the support.

[0017] Furthermore, the second driving device also includes a second power device, which is disposed on the frame and is used to drive each of the second clamping members to move back and forth in each of the first clamping spaces along the conveying direction of the conveyor line and to enable each of the second clamping members to move synchronously with each of the first clamping members.

[0018] Furthermore, the present invention also includes an adjustment unit, which includes a pressing seat and a third driving device. The pressing seat is movably disposed on the frame so that it can extend and retract along the height direction of the packaging box being conveyed on the conveyor line. The third driving device is disposed on the frame. When a packaging box on one conveying station is clamped by a first clamping space and moved to another conveying station, the pressing seat moves toward the support seat under the drive of the third driving device so that it can press against the packaging box on the other conveying station.

[0019] Furthermore, the adjustment unit also includes a plurality of third clamping members, each of which is retractably mounted on the frame. The retraction direction of each third clamping member is the same as that of the pressing seat. A second clamping space is formed between each pair of adjacent third clamping members. Starting from the beginning of the conveyor line, the first conveying station is a loading station, and the second and subsequent conveying stations are all working stations. Each second clamping space corresponds one-to-one with each working station. The adjustment unit also includes a plurality of fourth clamping members, each of which is movably and retractably mounted on the frame. Each fourth clamping member is located within each of the second clamping spaces. The retraction direction of each fourth clamping member is the same as that of each third clamping member. The third driving device is also used to drive the retraction of each third clamping member, the retraction of each fourth clamping member, and the reciprocating movement of each fourth clamping member within each of the second clamping spaces along the conveying direction of the conveyor line to adjust the size of each of the second clamping spaces.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] In use, this invention involves a first driving device that extends each of the first clamping members to place the package to be packed on the first conveying station. The first clamping space then clamps the package placed on the first conveying station. When the size of the package held in each of the first clamping spaces needs to be adjusted, a second driving device extends each of the second clamping members, causing the second clamping members within each of the first clamping spaces to move back and forth along the direction the package is being conveyed, thus adjusting the size of each of the first clamping spaces. By simultaneously activating the first and second driving devices, each of the first and second clamping members can be driven to move synchronously along the conveying direction. When the package held in the first clamping space moves from the first conveying station to the second conveying station, the first and second driving devices drive each of the first clamping members... The first and second clamping members retract and detach from the packaging box located at the second conveying station, and the first and second clamping members move synchronously to their original state. Then, through the first and second driving devices, the first and second clamping members extend, placing the new packaging box to be packed on the first conveying station and clamping it through the first clamping space to move it to the second conveying station. Meanwhile, the packaging box originally placed on the second conveying station is clamped by the second clamping space and moved to the third conveying station. This cycle is repeated, so that the automatic cartoning machine of the present invention can circulate and transport packaging boxes between different conveying stations on its clamping conveyor line and can automatically adjust the size of the clamped packaging box according to the size of the packaging box to suit packaging boxes of different sizes. It has high flexibility and strong applicability. Attached Figure Description

[0031] Implementation method:

[0032] Please refer to Figures 1-5 This invention discloses an automatic cartoning machine, including a frame 10 and at least one clamping conveyor line. Each clamping conveyor line includes a support, a first clamping device, and a second clamping device. Specifically, the support is disposed on the frame 10 and arranged along the conveying direction of the conveyor line. Multiple conveying stations are arranged on the support along the conveying direction of the conveyor line. Starting from the beginning of the conveyor line, the conveying station located closest to the beginning of the conveyor line is the first conveying station, followed by the second conveying station, and so on. The first clamping device includes a first driving device and a plurality of first clamping members 20. Each first clamping member 20 is movably disposed on the frame 10 along the direction in which the packaging box is conveyed and can extend and retract along the direction perpendicular to the support. The first driving device is disposed on the frame 10 and is used to drive each first clamping member 20 to extend, retract and move synchronously. A first clamping space is formed between each pair of adjacent first clamping members 20. Each first clamping space is used to clamp the packaging box 40 placed on each conveying station, that is, each first clamping space corresponds one-to-one with each conveying station. The second clamping device includes a second driving device and a plurality of second clamping members 30. Each second clamping member 30 is movably mounted on the frame 10 along the conveying direction of the conveyor line and can extend and retract in a direction perpendicular to the support. That is, the movement of each second clamping member 30 is the same as that of each first clamping member 20. The second driving device is mounted on the frame 10 and is used to drive each second clamping member 30 to extend and retract, move each second clamping member 30 within each first clamping space, and move each second clamping member 30 synchronously with each first clamping member 20, so as to adjust the size of each first clamping space.

[0033] In summary, when in use, the first driving device drives each of the first clamping members 20 to extend, placing the packaging box 40 to be packaged on the first conveying station. The packaging box 40 placed on the first conveying station is clamped by the first clamping space. When it is necessary to adjust the size of the packaging box 40 clamped in each of the first clamping spaces, the second driving device drives each of the second clamping members 30 to extend and move back and forth along the direction in which the packaging box is conveyed, thereby adjusting the size of each of the first clamping spaces. At this time, by simultaneously activating the first driving device and the second driving device, each of the first clamping members 20 and each of the second clamping members 30 can be driven to move synchronously along the conveying direction. When the packaging box 40 clamped in the first clamping space moves from the first conveying station to the second conveying station, the first driving device and the second driving device drive each of the first clamping members 20 to extend. The first clamping member 20 and each of the second clamping members 30 retract and disengage from the packaging box 40 located at the second conveying station, and the first clamping member 20 and each of the second clamping members 30 move synchronously back to their original state. Then, through the first driving device and the second driving device, the first clamping member 20 and each of the second clamping members 30 extend, placing the new packaging box 40 to be boxed on the first conveying station and clamping it through the first clamping space to move it to the second conveying station. Meanwhile, the packaging box 40 originally placed on the second conveying station is clamped by the second clamping space and moved to the third conveying station. This cycle is repeated, so that the automatic boxing machine of the present invention can circulate and transport the packaging box 40 between different conveying stations on its clamping conveyor line and can automatically adjust the size of the clamping packaging box 40 according to the size of the packaging box 40 to suit packaging boxes 40 of different sizes. It has high flexibility and strong applicability.

[0034] In this embodiment, the extension and retraction directions of each first clamping member 20 and each second clamping member 30 are the same. Each first clamping member 20 and each second clamping member 30 extends and retracts vertically along the height direction of the frame 10 to facilitate their layout and avoid the second clamping member 30 occupying additional space. Of course, in other embodiments, the extension and retraction directions of each second clamping member 30 and each first clamping member 20 can also be perpendicular. Specifically, each first clamping member 20 extends and retracts vertically along the height direction of the frame 10, while each second clamping member 30 is arranged horizontally perpendicular to the conveyor line conveying the packaging box 40. In this way, the size of the packaging box 40 clamped within each first clamping space can be adjusted by driving each second clamping member 30 to move within each first clamping space using the second driving device. Therefore, no limitation is made here. For those skilled in the art, reasonable changes to the arrangement of each first clamping member 20 and each second clamping member 30 should also fall within the protection scope of this invention.

[0035] The present invention also includes an adjustment unit, which includes a pressing seat and a third driving device. The pressing seat is movably disposed on the frame 10 so that the pressing seat can extend and retract along the height direction of the packaging box 40 conveyed on the conveyor line. The third driving device is disposed on the frame 10. When the packaging box 40 on one conveying station is clamped by the first clamping space corresponding to the conveying station and moved to another conveying station, the pressing seat moves toward the support seat under the drive of the third driving device so that the pressing seat can press against the upper surface of the packaging box 40 on the other conveying station. Those skilled in the art will understand that when the first clamping space clamps the packaging box 40 and moves it from the first conveying station to the second conveying station, the first driving device and the second driving device drive each first clamping member 20 and each second clamping member 30 to retract and disengage from the packaging box 40 located at the second conveying station. At the same time, the third driving device drives the pressure seat to descend and press against the upper surface of the packaging box 40 located at the second conveying station. This facilitates the feeding device of the cartoning machine to accurately push the medicine to be cartoned into the packaging box 40 (such as pushing the instruction manual and blister pack into the medicine box), and prevents the packaging box 40 from shifting upward during the cartoning process.

[0036] It should be noted that the feeding device involved in this embodiment adopts the structure of the feeding device in the existing cartoning machine, and will not be described in detail here.

[0037] In this embodiment, the adjustment unit further includes a plurality of third clamping members 50 and a plurality of fourth clamping members 60. Each third clamping member 50 is telescopically mounted on the frame 10. The third clamping members 50 are spaced apart to form a row of third clamping members 50 parallel to the direction in which the packaging box is conveyed. The telescopic direction of each third clamping member 50 is the same as the telescopic direction of the pressing seat. A second clamping space is formed between each pair of adjacent third clamping members 50. Starting from the beginning of the conveyor line, the first conveying station is the loading station, and the second and subsequent conveying stations are all working stations. Each second clamping space corresponds one-to-one with each working station. In addition, each fourth clamping member 60 is movably and telescopically mounted on the frame 10. The telescopic direction of each fourth clamping member 60 is the same as that of each third clamping member 50. Each fourth clamping member 60 is located within each second clamping space. The third driving device is also used to drive each third clamping member 50 to telescopically extend and retract, each fourth clamping member 60 to telescopically extend and retract, and each fourth clamping member 60 to move back and forth within each second clamping space along the conveying direction of the conveyor line, so as to adjust the size within each second clamping space. In other words, when the first clamping space clamps the packaging box 40 and moves it from the first conveying station to the second conveying station (equivalent to the first clamping space clamping the packaging box 40 moving from the loading station to the first working station), the first and second driving devices drive each first clamping member 20 and each second clamping member 30 to retract and disengage from the packaging box 40 located at the second conveying station. At the same time, the fourth driving device drives each third clamping member 50 and each fourth clamping member 60 to extend and retract, and each fourth clamping member 60 to move back and forth along the conveying direction of the conveyor line within each second clamping space. This achieves the adjustment of the size of each second clamping space to facilitate clamping the packaging box 40 at the second conveying station, so as to be suitable for clamping packaging boxes 40 of different sizes, while avoiding the front and rear ends of the packaging box 40 shifting (tilting phenomenon) along the conveying direction of the packaging box during the boxing process.

[0038] It is worth noting that in this embodiment, the packaging box 40 is supported by the support seat, the packaging box 40 at each working station is pressed by the pressing seat, and the packaging box 40 at each working station is clamped by each second clamping space, so as to prevent the packaging box 40 from deviating during the boxing process, thereby achieving the function of accurately positioning the packaging box 40.

[0039] In this embodiment, the support includes a first support bar 11 and a second support bar 12 arranged in parallel at intervals. The first support bar 11 is fixed on the frame 10 along the conveying direction of the conveyor line. A movable bracket is also provided on the frame 10. The second support bar 12 is fixed on the movable bracket along the conveying direction of the conveyor line and is located in the same plane as the first support bar 11. A plurality of first clamping members 20 are arranged along the conveying direction of the conveyor line and are respectively spaced outside the first support bar 11 and the second support bar 12. The movable bracket is movably arranged on the frame 10 so that the second support bar 12 can move toward or away from the first support bar 11. Therefore, it can be understood that in this embodiment, the packaging box 40 is supported by the first support strip 11 and the second support strip 12. That is, one side of the packaging box 40 is supported by the first support strip 11, and the other side of the packaging box 40 is supported by the second support strip 12. When it is necessary to adjust the distance between the first support strip 11 and the second support strip 12 according to the different sizes of the packaging boxes 40, the moving bracket can be moved towards or away from the first support strip 11. Of course, a fourth driving device is also provided on the frame 10. The fourth driving device drives the moving bracket to move towards or away from the first support strip 11, thereby realizing the automatic adjustment effect of the distance between the first support strip 11 and the second support strip 12, so as to improve production efficiency.

[0040] In this embodiment, the pressing seat includes a first pressing strip 13 and a second pressing strip 14 arranged parallel to each other. The first pressing strip 13 is fixed on the frame 10 along the conveying direction of the conveyor line, and is located above and corresponds to the first supporting strip 11. The second pressing strip 14 is arranged on the movable bracket along the conveying direction of the conveyor line and is arranged parallel to and spaced apart from the first pressing strip 13. Of course, the first pressing strip 13 and the second pressing strip 14 are located in the same plane, and the second pressing strip 14 is located above and corresponds to the second supporting strip 12. Multiple third clamping members 50 are arranged along the conveying direction of the conveyor line and are respectively spaced outside the first pressing bar 13 and the second pressing bar 14. Of course, each third clamping member 50 located inside the first pressing bar 13 corresponds to each first clamping member 20 located outside the first supporting bar 11 and is staggered. In this way, when each first clamping member 20 and each second clamping member 30 rises, each third clamping member 50 and each fourth clamping member 60 falls, interference between each first clamping member 20 and each second clamping member 30 and each third clamping member 50 and each fourth clamping member 60 is avoided.

[0041] In this embodiment, the first driving device includes a first telescopic device, which is mounted on the frame 10 and is used to drive each first clamping member 20 to extend and retract along a vertical direction perpendicular to the support. That is, it can be understood that since each first clamping member 20 in this embodiment extends and retracts along the height of the frame 10, the first telescopic device drives each first clamping member 20 to extend and retract along a vertical direction perpendicular to the support. The first telescopic device in this embodiment includes a plurality of first cylinders 21, the number of which is the same as the number of first clamping members 20, i.e., each first clamping member 20 corresponds to one first cylinder 21. The telescopic end of each first cylinder 21 is connected to each first clamping member 20, thereby realizing the telescopic action of each first clamping member 20. Of course, each first cylinder 21 connected to each first clamping member 20 located on the outside of the first support bar 11 is fixed on the frame 10; each first cylinder 21 connected to each first clamping member 20 located on the outside of the second support bar 12 is fixed on a movable bracket.

[0042] Of course, in other embodiments, each of the first clamping members 20 located on the outer side of the first support bar 11 can be connected to a first cylinder 21 via a connecting plate, and each of the first clamping members 20 located on the outer side of the second support bar 12 can also be connected to a first cylinder 21 via a connecting plate, thus achieving the purpose of driving each of the first clamping members 20 to extend and retract. Therefore, for those skilled in the art, by reasonably changing the way each of the first clamping members 20 is connected to each of the first cylinders 21 and the number of the first cylinders 21, it should also fall within the protection scope of this invention; of course, the number of the first clamping members 20 is also reasonably selected by the inventor based on the actual use situation, and is not limited here. Therefore, for those skilled in the art, by reasonably changing the number of the first clamping members 20, it should also fall within the protection scope of this invention.

[0043] In addition, in other embodiments, the first cylinder 21 can also be replaced by a linear drive motor, an electric push or other lifting mechanism, which is not limited here. Therefore, for those skilled in the art, by reasonably changing the structure of the first telescopic device, it should also fall within the protection scope of the present invention.

[0044] In this embodiment, the first driving device further includes a first power device, which is mounted on the frame 10 and is used to drive each of the first clamping members 20 to move back and forth synchronously along the conveying direction of the conveyor line. Specifically, the first power device includes a first driving unit and a second driving unit. The first driving unit is mounted on the frame 10 and is used to drive each of the first clamping members 20 located outside the first support bar 11 to move back and forth along the conveying direction of the conveyor line. The second driving unit is mounted on the movable bracket and is used to drive each of the first clamping members 20 located outside the second support bar 12 to move back and forth along the conveying direction of the conveyor line. Specifically, the first drive unit and the second drive unit have the same structure. The first drive unit includes a first servo motor 22 and a first electric cylinder 23. The first servo motor 22 is mounted on the frame 10 and its output shaft is connected to the ball screw inside the first electric cylinder 23 via a coupling. The first electric cylinder 23 is positioned parallel to the direction of the conveyor line. The ball screw inside the first electric cylinder 23 drives the first electric cylinder slider 230 on the outer wall of the first electric cylinder 23 to move along the length of the first electric cylinder 23. The first electric cylinder slider 230 is connected to the first fixed guide rail 231. The first fixed guide rail 231 is connected to each of the first clamping members 20 located outside the first support bar 11. That is, the first electric cylinder slider 230 drives the first fixed guide rail 231 to move, thereby realizing the movement of each of the first clamping members 20 located outside the first support bar 11.

[0045] Similarly, the second drive unit includes a second servo motor 24 and a second electric cylinder 25. The second servo motor 24 is fixed to the frame 10 by a movable bracket. The output shaft of the second servo motor 24 is also connected to the ball screw in the second electric cylinder 25 by a coupling. The setting direction of the second electric cylinder 25 is parallel to the conveying direction of the conveyor line. The ball screw in the second electric cylinder 25 drives the second electric cylinder slider 250 on the outer wall of the second electric cylinder 25 to move along the length direction of the second electric cylinder 25. The second electric cylinder slider 250 is connected to the second fixed guide rail 251. The second fixed guide rail 251 is connected to each of the first clamping members 20 located outside the second support bar 12. That is, the second electric cylinder slider 250 drives the second fixed guide rail 251 to move, thereby realizing the movement of each of the first clamping members 20 located outside the second support bar 12.

[0046] Of course, in other embodiments, the first drive unit and / or the second drive unit may also be an electric push rod or a linear drive motor, etc., and are not limited here. Therefore, for those skilled in the art, by reasonably changing the structure and position of the first drive unit and / or the second drive unit, it should also fall within the protection scope of the present invention.

[0047] In this embodiment, the second driving device includes a second telescopic device, which is mounted on the frame 10 and used to drive each second clamping member 30 to extend and retract along a vertical direction perpendicular to the support. That is, since each second clamping member 30 in this embodiment extends and retracts along the height of the frame 10, the second telescopic device drives each second clamping member 30 to extend and retract along a vertical direction perpendicular to the support. The second telescopic device in this embodiment includes a plurality of second cylinders 31, the number of which is the same as the number of second clamping members 30. That is, each second clamping member 30 corresponds to one second cylinder 31; the telescopic end of each second cylinder 31 is connected to each second clamping member 30, thereby realizing the telescopic action of each second clamping member 30. Of course, each second cylinder 31 connected to each second clamping member 30 located on the outside of the first support bar 11 is fixed on the frame 10; each second cylinder 31 connected to each second clamping member 30 located on the outside of the second support bar 12 is fixed on the movable bracket.

[0048] Of course, in other embodiments, each of the second clamping members 30 located on the outer side of the second support strip 12 can be connected to a second cylinder 31 via a connecting plate, and each of the second clamping members 30 located on the outer side of the second support strip 12 can also be connected to a second cylinder 31 via a connecting plate, thus achieving the purpose of driving each of the second clamping members 30 to extend and retract. Therefore, for those skilled in the art, by reasonably changing the way each of the second clamping members 30 is connected to each of the second cylinders 31 and the number of the second cylinders 31, it should also fall within the protection scope of this invention; of course, the number of the second clamping members 30 is also reasonably selected by the inventor based on the actual use situation, and is not limited here. Therefore, for those skilled in the art, by reasonably changing the number of the second clamping members 30, it should also fall within the protection scope of this invention.

[0049] In addition, in other embodiments, the second cylinder 31 can also be replaced by a linear drive motor, an electric push or other lifting mechanism, which is not limited here. Therefore, for those skilled in the art, by reasonably changing the structure of the second telescopic device, it should also fall within the protection scope of the present invention.

[0050] In this embodiment, the second driving device further includes a second power device, which is mounted on the frame 10 and is used to drive each second clamping member 30 to move back and forth within each first clamping space along the conveying direction of the conveyor line, and to enable each second clamping member 30 to move synchronously with each first clamping member 20. Specifically, the second power device includes a third driving unit and a fourth driving unit. The third driving unit is mounted on the frame 10 and is used to drive each second clamping member 30 located outside the first support bar 11 to move back and forth along the conveying direction of the conveyor line. The fourth driving unit is mounted on the movable bracket and is used to drive each second clamping member 30 located outside the second support bar 12 to move back and forth along the conveying direction of the conveyor line. Specifically, the third drive unit and the fourth drive unit have the same structure. The third drive unit includes a third servo motor 32 and a third electric cylinder 33. The third servo motor 32 is mounted on the frame 10 and its output shaft is connected to the ball screw inside the third electric cylinder 33 via a coupling. The third electric cylinder 33 is positioned parallel to the direction of the conveyor line. The ball screw inside the third electric cylinder 33 drives the third electric cylinder slider 330 on the outer wall of the third electric cylinder 33 to move along the length of the third electric cylinder 33. The third electric cylinder slider 330 is connected to the third fixed guide rail 331. The third fixed guide rail 331 is connected to each of the second clamping members 30 located outside the first support bar 11. That is, the third electric cylinder slider 330 drives the third fixed guide rail 331 to move, thereby realizing the movement of each of the second clamping members 30 located outside the first support bar 11.

[0051] Similarly, the fourth drive unit includes a fourth servo motor 34 and a fourth electric cylinder 35. The fourth servo motor 34 is fixed to the frame 10 by a movable bracket. The output shaft of the fourth servo motor 34 is also connected to the ball screw in the fourth electric cylinder 35 by a coupling. The setting direction of the fourth electric cylinder 35 is parallel to the conveying direction of the conveyor line. The ball screw in the fourth electric cylinder 35 drives the fourth electric cylinder slider 350 on the outer wall of the fourth electric cylinder 35 to move along the length direction of the fourth electric cylinder 35. The fourth electric cylinder slider 350 is connected to the fourth fixed guide rail 351. The fourth fixed guide rail 351 is connected to each of the second clamping members 30 located outside the second support bar 12. That is, the fourth fixed guide rail 351 is moved by the fourth electric cylinder slider 350, thereby realizing the movement of each of the second clamping members 30 located outside the second support bar 12.

[0052] It should be noted that the travel distance of each second clamping member 30 within each first clamping member 20 is different from the travel distance of each second clamping member 30 moving synchronously with each first clamping member 20.

[0053] Of course, in other embodiments, the third drive unit and / or the fourth drive unit may also be an electric push rod or a linear drive motor, etc., and are not limited here. Therefore, for those skilled in the art, by reasonably changing the structure and position of the third drive unit and / or the fourth drive unit, it should also fall within the protection scope of the present invention.

[0054] In this embodiment, the third driving device includes a first lifting device and a second lifting device. The first lifting device is mounted on the frame 10 and is used to drive each third clamping member 50 and each fourth clamping member 60 located inside the first pressing bar 13 to move up and down along the height direction of the frame 10. The second lifting device is mounted on the frame 10 and is used to drive each third clamping member 50 and each fourth clamping member 60 located outside the second pressing bar 14 to move up and down along the height direction of the frame 10.

[0055] Specifically, the first lifting device includes a first lifting structure and multiple first lifting units. The first lifting structure includes a fifth servo motor 53 and a fifth electric cylinder 530 arranged opposite to each other. Each fifth electric cylinder 530 is arranged and fixed on the frame 10 in a vertical direction perpendicular to the direction in which the packaging box is conveyed. The fifth servo motor 53 is arranged and fixed on the frame 10 in a vertical direction perpendicular to the direction in which the packaging box is conveyed. The output shaft of the fifth servo motor 53 is connected to the ball screw of the fifth electric cylinder 530 through a coupling. The ball screw of the fifth electric cylinder 530 drives the slider of the fifth electric cylinder 530 on the outer wall of the fifth electric cylinder 530 to move along the length direction of the fifth electric cylinder 530. The slider of the fifth electric cylinder 530 is connected to the fifth fixed guide rail 52 through a first sliding connecting block. The fifth fixed guide rail 52 is slidably connected to the frame 10, so that the fifth fixed guide rail 52 can be raised and lowered along the height direction of the frame 10. Of course, each of the third clamping members 50 located inside the first pressing bar 13 is fixed on the fifth fixed guide rail 52. Thus, the extension and retraction of each of the third clamping members 50 located inside the first pressing bar 13 can be achieved by the fifth electric cylinder 530 sliding block driving the fifth fixed guide rail 52 to rise and fall. In this embodiment, the first pressing bar 13 is fixed along the conveying direction of the conveyor line to the outside of each of the third clamping members 50 located inside the first pressing bar 13; the second pressing bar 14 is fixed along the conveying direction of the conveyor line to the outside of each of the third clamping members 50 located inside the second pressing bar 14, so that the first pressing bar 13 and the second pressing bar 14 rise and fall with the rise and fall of the third clamping members 50.

[0056] Of course, in other embodiments, the first lifting structure may also be a linear drive motor or an electric push rod, etc., so it is not limited here. For those skilled in the art, by reasonably changing the structure of the first lifting structure, it should also fall within the protection scope of this invention.

[0057] In this embodiment, the first lifting unit includes a first lifting cylinder 51 and a second lifting cylinder 61. Both the first lifting cylinder 51 and the second lifting cylinder 61 are arranged vertically. The number of first lifting cylinders 51 is the same as the number of third clamping members 50 located inside the first pressing bar 13, and the number of second lifting cylinders 61 is the same as the number of fourth clamping members 60 located inside the first pressing bar 13. That is, it can be understood that each third clamping member 50 located inside the first pressing bar 13 is connected to the telescopic end of a first lifting cylinder 51, and each fourth clamping member 60 located inside the first pressing bar 13 is connected to the telescopic end of a second lifting cylinder 61. Therefore, it can be seen that the first lifting cylinder 51, located inside the first pressing bar 13 and connected to each of the third clamping members 50 located inside the first pressing bar 13, is fixed on the fifth fixed guide rail 52. The lifting cylinder 51 located inside the first pressing bar 13 further drives the lifting of each of the third clamping members 50 located inside the first pressing bar 13; the second lifting cylinder located inside the second pressing bar further drives the lifting of each of the fourth clamping members 50 located inside the first pressing bar 13.

[0058] In addition, the first lifting device also includes a first moving drive unit, which includes a sixth servo motor 62 and a sixth electric cylinder 63. The setting direction of the sixth electric cylinder 63 is parallel to the conveying direction of the conveyor line. The output shaft of the sixth servo motor 62 is connected to the ball screw of the sixth electric cylinder 63. The sixth electric cylinder 63 is slidably connected to the sliding block of the fifth electric cylinder 530 through the first moving guide rail 65. The ball screw in the sixth electric cylinder 63 drives the sixth electric cylinder slider 631 on the outer wall of the sixth electric cylinder 63 to move along the length direction of the sixth electric cylinder 63. The sixth electric cylinder slider 631 is connected to the sixth fixed guide rail 64. Each fourth clamping member 60 located inside the first pressing bar 13 is spaced on the sixth fixed guide rail 64 along the conveying direction of the packaging box 40, so that each fourth clamping member 60 located inside the first pressing bar 13 can move within the second clamping space formed by two adjacent third clamping members 50 located inside the first pressing bar 13. Of course, each of the fourth clamping members 60 located inside the first pressing bar 13 is connected and fixed to the sixth fixed guide rail 64 via the second lifting cylinder 61. That is, each of the fourth clamping members 60 located inside the first pressing bar 13 is connected to the telescopic end of the second lifting cylinder 61, thereby further driving the fourth clamping member 60 to rise and fall via the second lifting cylinder 61. Since the sixth fixed guide rail 64 is slidably connected to the sliding block of the fifth electric cylinder 530 via the first moving guide rail 65, each of the third clamping members 50 and each of the fourth clamping members 60 located inside the first pressing bar 13 can rise and fall synchronously.

[0059] In this embodiment, the second lifting device has the same structure as the first lifting device. The second lifting device includes a second lifting structure and multiple second lifting units. Each second lifting unit is symmetrically arranged with respect to each first lifting unit. The second lifting structure includes a seventh servo motor 70 and a seventh electric cylinder 71 arranged opposite to each other. Each seventh electric cylinder 71 is arranged and fixed on the frame 10 in a vertical direction perpendicular to the direction in which the packaging box is conveyed. The seventh servo motor 70 is arranged and fixed on the frame 10 in a vertical direction perpendicular to the direction in which the packaging box is conveyed. The output shaft of the seventh servo motor 70 is connected to the ball screw of the seventh electric cylinder 71 through a coupling. The ball screw of the seventh electric cylinder 71 drives the slider of the seventh electric cylinder 71 on the outer wall of the seventh electric cylinder 71 to move along the length direction of the seventh electric cylinder 71. The slider of the seventh electric cylinder 71 is connected to the seventh fixed guide rail 72 through a second sliding connecting block. The seventh fixed guide rail 72 is slidably connected to the frame 10, so that the seventh fixed guide rail 72 can move up and down along the height direction of the frame 10. Of course, each of the third clamping members 50 located inside the second pressing bar 14 is fixed on the seventh fixed guide rail 72. Thus, the extension and retraction of each of the third clamping members 50 located inside the second pressing bar 14 can be achieved by the seventh electric cylinder 71 sliding block driving the seventh fixed guide rail 72 to rise and fall. Of course, in other embodiments, the second lifting structure can also be a linear drive motor or an electric push rod, etc., so it is not limited here. For those skilled in the art, reasonable modifications to the structure of the second lifting structure should also fall within the protection scope of this invention.

[0060] In this embodiment, the second lifting unit also includes multiple first lifting cylinders 51 and second lifting cylinders 61. Each third clamping member 50 located inside the second pressing bar 14 is connected to the telescopic end of a first lifting cylinder 51, and each fourth clamping member 60 located inside the second pressing bar 14 is connected to the telescopic end of a second lifting cylinder 61. Therefore, the first lifting cylinders 51 located inside the second pressing bar 14 and connected to each of the third clamping members 50 located inside the second pressing bar 14 are fixed on the seventh fixed guide rail 72. The lifting of each of the third clamping members 50 located inside the second pressing bar 14 can be further driven by the first lifting cylinders 51 located inside the second pressing bar 14; and the lifting of each of the fourth clamping members located inside the second pressing bar 14 can be further driven by the second lifting cylinders located inside the second pressing bar 14.

[0061] In addition, the second lifting device also includes a second moving drive unit, which includes an eighth servo motor 80 and an eighth electric cylinder 81. The eighth electric cylinder 81 is set in a direction parallel to the direction of the conveyor line. The output shaft of the eighth servo motor 80 is connected to the ball screw of the eighth electric cylinder 81. The eighth electric cylinder 81 is slidably connected to the slider of the seventh electric cylinder 71 through the second moving guide rail 83. The ball screw inside the eighth electric cylinder 81 drives the slider 810 of the eighth electric cylinder on the outer wall of the eighth electric cylinder 81 to move along the length direction of the eighth electric cylinder 81. The slider 810 of the eighth electric cylinder is connected to the eighth fixed guide rail 82. Each fourth clamping member 60 located inside the second pressing bar 14 is spaced apart on the eighth fixed guide rail 82 along the direction in which the packaging box 40 is conveyed, so that each fourth clamping member 60 located inside the second pressing bar 14 can move within the second clamping space formed by two adjacent third clamping members 50 located inside the second pressing bar 14. Of course, each of the fourth clamping members 60 located inside the second pressing bar 14 is connected and fixed to the eighth fixed guide rail 82 via the second lifting cylinder 61. That is, each of the fourth clamping members 60 located inside the second pressing bar 14 is connected to the telescopic end of the second lifting cylinder 61, thereby further driving the fourth clamping member 60 to rise and fall via the second lifting cylinder 61. Since the eighth fixed guide rail 82 is slidably connected to the eighth electric cylinder slider 810 via the second moving guide rail 83, each of the third clamping members 50 and each of the fourth clamping members 60 located inside the second pressing bar 14 can rise and fall synchronously.

[0062] In this embodiment, refer to Figure 5 The aforementioned movable support is slidably connected to the frame 10 via a crossbeam linear guide rail 92. The movable support includes an upper support 93 and a lower support 94. The upper support 93 is located above the lower support 94, meaning it is connected via the crossbeam linear guide rail 92. The lower support 94 is slidably connected to the frame 10 via a support guide rail 96. The upper support 93 and the lower support 94 are slidably connected via a vertically arranged connecting sliding guide rail 95, allowing the upper support 93 to rise and fall along the vertical direction of the connecting sliding guide rail 95. The aforementioned first clamping members 20 and second clamping members 30 located outside the second support bar 12 are mounted on the lower support 94, while the third clamping members 50 and fourth clamping members 60 located inside the second pressing bar 14 are mounted on the upper support 93. It can be seen that the third clamping member 50 and the fourth clamping member 60 on opposite sides of the pressing seat are driven to rise and fall by the linear guide rail 92 of the crossbeam. Therefore, the third clamping member 50 and the fourth clamping member 60 on the inner side of the first pressing bar 13 and the second pressing bar 14 can rise and fall synchronously.

[0063] Of course, in other embodiments, the second lifting structure may also be a linear drive motor or an electric push rod, etc., so it is not limited here. For those skilled in the art, by reasonably changing the structure of the second lifting structure, it should also fall within the protection scope of this invention.

[0064] It should be noted that the number of the first lifting cylinder 51 and the second lifting cylinder 61 is not limited in this embodiment, and can be reasonably selected and changed by the inventor according to the actual use. Therefore, for those skilled in the art, by reasonably changing the number of the first lifting cylinder 51 and the second lifting cylinder 61, it should also fall within the protection scope of this invention.

[0065] In this embodiment, the fourth driving device includes a ninth servo motor 90 and a ninth electric cylinder 91. Both the ninth servo motor 90 and the ninth electric cylinder 91 are arranged along the horizontal direction perpendicular to the packaging box 40 being conveyed. The ninth servo motor 90 is fixed on the frame 10. The output shaft of the ninth servo motor 90 is driven to the ball screw of the ninth electric cylinder 91 through a coupling. The ball screw of the ninth electric cylinder 91 drives the ninth electric cylinder slider on the outer wall of the ninth electric cylinder 91 to move along the length direction of the ninth electric cylinder 91. The ninth electric cylinder slider is connected and fixed to the upper bracket 93 through a third sliding connecting block, so that the ninth electric cylinder slider drives the upper bracket 93 to move toward or away from the first support bar 11. The movement of the upper bracket 93 also drives the lower bracket 94 to move toward or away from the first support bar 11, thereby adjusting the distance between the first support bar 11 and the second support bar 12.

[0066] Of course, in other embodiments, the fourth driving device may also be a linear drive motor or an electric push rod, etc., so it is not limited here. For those skilled in the art, by reasonably changing the structure of the fourth driving device, it should also fall within the protection scope of this invention.

[0067] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
