Description

Technical Field

[0001] This invention relates to the field of packaging machinery technology, and more specifically to a rotating box-picking device. Background Technology

[0002] A cartoning machine is a mechanical device that loads materials into cartons. The carton-retrieving device is an important component of the cartoning machine. Its function is to pick up flat cartons from the carton hopper and transfer them to the carton conveying device. During the transfer process, the flat cartons are opened into three-dimensional cartons. The carton conveying device transports the three-dimensional cartons forward, and finally, the pushing device pushes the materials into the three-dimensional cartons.

[0003] The existing cardboard box retrieval device includes a mounting base, a power source, a main shaft, a central fixed gear, a revolving disk, and several suction rod assemblies. The suction rod assemblies can both revolve around the central disk and rotate on their own axis, thereby adsorbing the cardboard box.

[0004] For example, a utility model patent with a publication date of October 16, 2020, publication number CN211685852U, and titled "A Suction Box Transfer Device" includes a mounting base, a power source, a main shaft, a rotating disk, a central fixed gear, and several suction rod assemblies. The suction rod assembly includes a suction box nozzle and a suction box rod. The characteristic feature is that the suction box rod of each suction rod assembly is eccentrically mounted on a rotating disk. The rotating disk is rotatably mounted on the rotating disk via a rotating shaft. A planetary gear is mounted on the rotating shaft. A transition gear is rotatably mounted on the rotating disk. The planetary gear meshes with the transition gear, and the transition gear meshes with the central fixed gear.

[0005] When the aforementioned box-picking device places the three-dimensional cardboard box onto the box-carrying device, the box-carrying device needs to temporarily stop conveying. In other words, the box-carrying device must operate intermittently to accommodate the box-picking device's placement of the three-dimensional cardboard box; otherwise, it will affect the opening effect of the three-dimensional cardboard box and the positioning effect of the box-picking device. This severely impacts the conveying efficiency of the box-carrying device, and consequently, the efficiency of subsequent material packing. Summary of the Invention

[0006] To overcome the defects and shortcomings of the existing technology, this invention discloses a rotary box-picking device. The purpose of this invention is to solve the problem that existing box-picking devices require intermittent conveying of three-dimensional cartons by the carton-carrying device, which affects the conveying efficiency of the carton-carrying device and hinders accurate placement of the cartons. The rotary box-picking device of this invention is mounted on a fixed mounting frame via a swing mounting bracket. A swing drive mechanism drives the swing mounting bracket to swing on the fixed mounting frame, thereby causing the rotary box-picking device to swing. When the suction rod assembly in the rotary box-picking device is at its lowest position, it undergoes a horizontal displacement under the drive of the swing drive mechanism, allowing it to adapt to the carton-carrying device. This rotary box-picking device can place three-dimensional cartons on a continuously conveying carton-carrying device with precise placement and positioning, maintaining the carton's posture without change. This improves the conveying efficiency of the carton-carrying device and consequently, increases the efficiency of subsequent material packing.

[0025] More preferably, the auxiliary plate mounting base is fixedly connected to the nozzle rod mounting base of the nozzle rod assembly.

[0026] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0027] 1. The rotating box-picking device of the present invention is mounted on a fixed mounting frame via a swing mounting bracket. A swing drive mechanism drives the swing mounting bracket to swing on the fixed mounting frame, thereby causing the rotating box-picking device to swing. When the suction rod assembly in the rotating box-picking device is at its lowest position, under the drive of the swing drive mechanism, the suction rod assembly has a horizontal displacement, which can be adapted to the box-carrying device. The rotating box-picking device with this configuration can place three-dimensional cartons on the continuously conveying box-carrying device with accurate placement and positioning, and the posture of the three-dimensional cartons will not change. This is beneficial to improving the conveying efficiency of the box-carrying device, and thus can improve the subsequent material boxing efficiency.

[0028] 2. In this invention, the swing drive mechanism transmits the power of the swing drive motor to the swing mounting frame through a translation component. This is because the entire rotating box-retrieving device needs to be installed on the swing mounting frame, and the rotating box-retrieving device has a large weight. Therefore, the moment of inertia of the swing mounting frame will also be relatively large. By transmitting the power through the translation component, the stability of the swing of the swing mounting frame can be ensured. The translation component can provide a certain support force to the swing mounting frame to ensure its stable swing.

[0029] 3. The fixed mounting frame of the present invention includes a support base and a top suspension. A lifting adjustment component is set through the connection between the top suspension and the support base to adjust the height of the top suspension, which can adapt to box retrieval operations under different height conditions and facilitate height adjustment.

[0030] 4. Compared with existing technologies, the rotating paper box picking device of this invention adds a transmission component II. Through the transmission component II, the sun gear gains rotational capability. By controlling the rotational speed of the sun gear, which is in sync with the rotational speed of the planetary disk, the rotational speed of the suction rod assembly is adjustable and controllable. When the rotational speed of the planetary disk is increased, the rotational speed of the sun gear can be controlled—that is, the difference between the rotational speeds of the sun gear and the planetary disk—to adjust and control the rotational speed of the suction rod assembly. This makes the paper box picking device more flexible, prevents the paper box from falling off due to excessive rotation of the suction rod assembly, improves the stability of the suction rod assembly's rotation, and increases the success rate of paper box picking and opening.

[0031] 5. The rotating box-retrieving device of the present invention integrates transmission component I and transmission component II together, resulting in a high degree of equipment integration and ensuring the coaxiality of the driving force of the stellar gear and the orbital disk, avoiding the uneven power transmission that often occurs with other transmission methods. The present invention assembles transmission component I and transmission component II together via a dual-shaft configuration, making the operation of the stellar gear and the orbital disk more stable.

[0032] 6. In this invention, transmission component I and transmission component II share the same power source, which can ensure the synchronization of the drive, save power source, and save equipment cost. It is only necessary to control the transmission ratio of the power source to the two transmission components to control the difference in their rotation speed, thereby realizing the control of the rotation speed of the nozzle rod assembly.

[0033] 7. The rotating retrieval box of the present invention drives transmission component I and transmission component II to rotate through two synchronous pulleys respectively. The transmission ratio of the two transmission components can be controlled by the difference in diameter of the two synchronous pulleys. The structure is simple and the cost is low.

[0034] 8. The suction rod assembly of the present invention, through the setting of the suction rod mounting base, allows the rotating surface of the suction end face of the suction rod to change from a circle to an ellipse, which increases the contact time between the suction rod and the paper box in the paper box material library. At the same time, it also helps to increase the contact time between the suction rod and the box opening component, ensuring the success rate of box retrieval and box opening.

[0035] 9. Compared with the prior art, the present invention provides a box-opening auxiliary mechanism on the nozzle rod assembly. After the nozzle rod assembly and the box-opening assembly work together to open the flat cardboard box to form a three-dimensional cardboard box, the box-opening auxiliary plate of the box-opening auxiliary mechanism swings to one side of the nozzle rod assembly, so that the box-opening auxiliary plate is parallel to the side wall in the thickness direction after the three-dimensional shape is formed, and supports the side wall, so as to prevent the three-dimensional cardboard box from returning to the flat cardboard box or the opening degree of the three-dimensional cardboard box from changing during the continued rotation of the nozzle rod assembly.

[0036] 10. This invention, through the structural arrangement of an opening-aid cam disc, an auxiliary plate mounting base, an opening-aid plate, an auxiliary connecting rod, an auxiliary swing arm, an auxiliary rotating sleeve, an auxiliary pull rod, and a cam transmission rod, enables the opening-aid mechanism to rotate and revolve coaxially with the nozzle rod assembly, ensuring that the opening-aid mechanism always moves in tandem with the nozzle rod assembly. Under the action of the opening-aid cam disc, no additional power source is required; the existing power source can still be used to achieve the swinging of the opening-aid plate in the opening-aid mechanism.

[0037] 11. The box opening assist mechanism of the present invention has a stable assisting effect on the three-dimensional cardboard box after it is opened, so that the three-dimensional cardboard box maintains its three-dimensional state and avoids it from resetting. By designing the cam groove trajectory of the box opening assist cam plate, the box opening assist plate can move at the same time or after the flat cardboard box picked up by the suction rod assembly is opened to form a three-dimensional cardboard box, thereby keeping the posture of the three-dimensional cardboard box unchanged and ensuring the success rate of the box opening device.

[0038] 12. This invention provides a connecting ear plate on the box-opening auxiliary plate. Through this connecting ear plate, the force transmitted by the auxiliary connecting rod is better received, allowing the box-opening auxiliary plate to swing at a set angle around its hinge axis with the auxiliary plate mounting base. The shape and length of the connecting ear plate can be optimized based on the angle of force transmission and the swing angle of the box-opening auxiliary plate.

[0039] 13. The suction rod assembly of the present invention adopts a hollow drive shaft III, which allows the box opening auxiliary mechanism to be integrated with the suction rod assembly, ensuring that the box opening auxiliary mechanism effectively follows the movement of the suction rod assembly, resulting in optimized structural layout and structural stability.

[0047] The following are exemplary embodiments of the invention as defined by the claims and their equivalents, taken in conjunction with the accompanying drawings, to aid in a comprehensive understanding. The specific details described herein are to be considered exemplary only and not to limit the scope of the invention. Therefore, those skilled in the art can make various changes and modifications to the embodiments without departing from the scope and spirit of the invention.

[0048] Example 1

[0049] As a preferred embodiment of the present invention, please refer to the appendix to the specification. Figure 1 Appendix Figure 2 and attached Figure 3 As shown, this embodiment discloses a rotating box-retrieving device. The rotating box-retrieving device is mounted on a fixed mounting frame 29 via a swing mounting bracket 28. The upper end of the swing mounting bracket 28 is connected to the fixed mounting frame 29 via a swing shaft 30. The swing mounting bracket 28 is connected to a swing drive mechanism 31. When the suction rod assembly 4 in the rotating box-retrieving device is in the lowest position, the swing drive mechanism 31 drives the swing mounting bracket 28 to swing around the swing shaft 30. The swing direction of the swing mounting bracket 28 is the same as the rotation direction of the rotating box-retrieving device. After the suction rod assembly 4 in the rotating box-retrieving device leaves the lowest position, the swing drive mechanism 31 drives the swing mounting bracket 28 to reset.

[0050] When the suction rod assembly 4 in the rotating box-picking device moves the three-dimensional paper box above the box-carrying device, and is ready to place the three-dimensional paper box into the box-carrying device, the swing drive mechanism 31 drives the swing mounting frame 28 to swing at a set angle, and the swing direction is the same as the conveying direction of the box-carrying device and the same as the rotation direction of the rotating box-picking device.

[0051] When the suction rod assembly 4 in the rotary box-picking device is in the position of releasing the three-dimensional carton, under the drive of the swing drive mechanism 31, the suction rod assembly 4 has a horizontal displacement, which can be adapted to the box-carrying device. The rotary box-picking device with this configuration can place three-dimensional cartons on the continuously conveying box-carrying device with accurate placement and positioning, and the posture of the three-dimensional carton will not change. This is conducive to improving the conveying efficiency of the box-carrying device, and thus can improve the subsequent material boxing efficiency.

[0052] As an example of this embodiment, the swing drive mechanism 31 can be selected from a drive cylinder, a synchronous belt drive, or a screw and nut structure for equivalent replacement.

[0053] As an example of this embodiment, the swing drive mechanism 31 includes a swing drive motor 32 and a drive swing arm 33. One end of the drive swing arm 33 is fixedly mounted on the output shaft of the drive motor, and the other end is fitted with the swing mounting bracket 28. The swing drive mechanism 31 also includes a translation component 34, which includes a fixed base 35 and a translation base 36. The translation base 36 is slidably fitted on the fixed base 35, and the other end of the drive swing arm 33 is hinged to the translation base 36. A connecting arm 37 is provided on the translation base 36, and the connecting arm 37 is hinged to the swing mounting bracket 28.

[0054] The swing drive mechanism 31 transmits the power of the swing drive motor 32 to the swing mounting frame 28 through a translation component 34. Since the entire rotating box-retrieving device needs to be installed on the swing mounting frame 28, and the rotating box-retrieving device is relatively heavy, the moment of inertia of the swing mounting frame 28 will also be relatively large. Through the translation component 34, the stability of the swing of the swing mounting frame 28 can be ensured. The translation component 34 can provide a certain support force to the swing mounting frame 28 to ensure its stable swing.

[0055] Example 2

[0056] As another preferred embodiment of the present invention, this embodiment is a further detailed description and supplement to the technical solution of the present invention based on the above-described embodiment 1. In this embodiment, reference is made to the appendix to the specification. Figure 1 Appendix Figure 2 and attached Figure 3 As shown, the fixed mounting bracket 29 includes a support base 38 and a top suspension 39. The swing mounting bracket 28 is mounted on the top suspension 39 via a swing shaft 30. The top suspension 39 is assembled with the support base 38 via a lifting adjustment assembly 40, which is used to adjust the height of the top suspension 39 relative to the support base 38. Lifting adjustment assemblies 40 are provided at both ends of the top suspension 39, and these assemblies rotate synchronously via a synchronous adjustment assembly 41. The synchronous adjustment assembly 41 includes a synchronous shaft 42 and bevel gear sets at both ends of the synchronous shaft 42. One bevel gear set engages with the lifting adjustment assembly 40 at one end of the top suspension 39 for transmission, and the other bevel gear set engages with the lifting adjustment assembly 40 at the other end of the top suspension 39 for transmission. The lifting adjustment assembly 40 includes a lifting screw and a support nut. The lifting screw is rotatably mounted on the top suspension 39, and the support nut is fixed on the support base 38. Support guide columns 43 are also provided between the two ends of the top suspension 39 and the support base 38.

[0057] Example 3

[0058] As another preferred embodiment of the present invention, this embodiment is a further detailed supplement and explanation of the technical solution of the present invention based on the above-described Embodiment 1 or Embodiment 2. In this embodiment, reference is made to the appendix to the specification. Figure 1 Appendix Figure 2 and attached Figure 3 As shown, the rotating box-retrieving device includes a mounting bushing, a planetary disk 1, a transmission assembly I2 that drives the planetary disk 1 to rotate, a sun gear 3 coaxially mounted with the planetary disk 1, and several suction rod assemblies 4 mounted on the planetary disk 1. The transmission assembly I2 is mounted on the swing mounting frame 28 via the mounting bushing. One end of the transmission assembly I2 is connected to the planetary disk 1, and the other end is connected to the power source 7. The planetary gears 5 in each suction rod assembly 4 mesh with the sun gear 3. The suction rod assembly 4 rotates around the sun gear 3 under the drive of the planetary disk 1 while also rotating on its own axis.

[0059] This embodiment also provides a novel rotating box-retrieving device. Based on the above structure, the rotating box-retrieving device further includes a transmission component II6, which is connected to the star gear 3. The transmission component II6 transmits the power from the power source 7 to the star gear 3, causing the star gear 3 to rotate.

[0060] In this embodiment, the transmission component II 6 enables the stellar gear 3 to rotate. By controlling the rotational speed of the stellar gear 3, its rotational speed is adjusted to match that of the orbital disk 1, thus achieving adjustability and controllability of the rotational speed of the nozzle rod assembly 4. When the rotational speed of the orbital disk 1 is increased, the rotational speed of the stellar gear 3 can be controlled, i.e., the difference between the rotational speeds of the stellar gear 3 and the orbital disk 1, thereby adjusting and controlling the rotational speed of the nozzle rod assembly 4. This makes the control of the box-retrieving device more flexible, avoids the situation where the box falls off due to excessive rotation of the nozzle rod assembly 4, improves the stability of the rotation of the nozzle rod assembly 4, and increases the success rate of box retrieval and box opening.

[0061] In one embodiment of this invention, transmission component II6 may include a transmission gear fixedly connected coaxially to the sun gear 3, and then a drive gear is fitted onto the motor so that the drive gear meshes with the transmission gear, thereby driving the sun gear 3 to rotate. Transmission component I2 retains its existing structure. This structure utilizes two power sources 7, and by controlling the driving force of the two power sources 7, the speed difference between the sun gear 3 and the orbital disk 1 can be controlled.

[0062] Example 4

[0063] As another preferred embodiment of the present invention, this embodiment is a further detailed supplement and explanation of the technical solution of the present invention based on the above-described embodiment 3. In this embodiment, reference is made to the appendix to the specification. Figure 5As shown, the transmission assembly I2 includes a transmission shaft I8, the front end of which is connected to the planetary disk 1, and the rear end of which is connected to the power source 7. The transmission shaft I8 has a hollow structure. The transmission assembly II6 includes a transmission shaft II9, which is coaxially assembled inside the hollow structure of the transmission shaft I. The front end of the transmission shaft II9 is ​​connected to the stellar gear 3, and the rear end of the transmission shaft II9 is ​​connected to the power source 7.

[0064] This embodiment integrates transmission component I2 and transmission component II6 together, resulting in a high degree of equipment integration and ensuring the coaxiality of the driving force of the stellar gear 3 and the orbital disk 1, avoiding the uneven power transmission that often occurs with other transmission methods. This invention assembles transmission component I2 and transmission component II6 together via a dual-shaft configuration, making the operation of the stellar gear 3 and the orbital disk 1 more stable.

[0065] As an example of this embodiment, transmission component I2 and transmission component II6 share the same power source 7. This power source 7 simultaneously drives transmission component I2 and transmission component II6 to rotate. The transmission ratios of the transmission components connected to the power source 7 for transmission component I2 and transmission component II6 are different. Sharing the same power source 7 for transmission component I2 and transmission component II6 ensures synchronous driving, saves power source 7, and reduces equipment costs. By controlling the transmission ratio of power source 7 to the two transmission components, the difference in their rotational speeds can be controlled, thereby controlling the rotational speed of the nozzle rod assembly 4.

[0066] As another example of this embodiment, similar to Embodiment 1 above, two power sources 7 are used for driving.

[0067] When a single power source 7 drives two transmission components simultaneously, transmission component I2 further includes a synchronous pulley I10, and transmission component II6 further includes a synchronous pulley II11. Synchronous pulley I10 is fixed to transmission shaft I8, and synchronous pulley II11 is fixed to transmission shaft II9. The power source 7 drives synchronous pulleys I10 and II11 to rotate via synchronous belts. By driving transmission component I2 and transmission component II6 to rotate via two synchronous pulleys respectively, the transmission ratio of the two transmission components can be controlled by the difference in the diameters of the two synchronous pulleys. This design is simple and has a low cost.

[0068] Example 5

[0069] As another preferred embodiment of the present invention, this embodiment further supplements and elaborates on the technical solution of the present invention based on the above-described embodiment 3 or embodiment 4. In this embodiment, the suction rod assembly 4 includes a suction rod mounting base 12, a suction rod 13, a drive shaft III 14, and a planetary gear 5. The suction rod 13 is mounted on the suction rod mounting base 12. The suction rod mounting base 12 is fixedly connected to one end of the drive shaft III 14, and the other end of the drive shaft III 14 is connected to the planetary gear 5. The planetary gear 5 meshes with the sun gear 3, driving the drive shaft III 14 to rotate. The drive shaft III 14 drives the suction rod mounting base 12 to rotate, and the suction rod mounting base 12 drives the suction rod 13 to rotate around the drive shaft III 14. By setting the suction rod mounting base 12, the surface of the suction end face of the suction rod 13 can be changed from a circle to an ellipse, which increases the contact time between the suction rod 13 and the paper boxes in the paper box material library. At the same time, it also helps to increase the contact time between the suction rod 13 and the box opening component 24, ensuring the success rate of box retrieval and box opening.

[0070] Example 6

[0071] As another preferred embodiment of the present invention, this embodiment is a further detailed supplement and explanation of the technical solution of the present invention based on the above-described embodiments 3, 4, or 5, with reference to the appendix to the specification. Figure 1 Appendix Figure 2 and attached Figure 6 As shown, the box-removing device also includes a box-opening auxiliary mechanism 15, which includes a box-opening auxiliary cam disk 16, an auxiliary plate mounting base 17, a box-opening auxiliary plate 18, an auxiliary connecting rod 19, an auxiliary swing arm 20, an auxiliary rotating sleeve 21, an auxiliary pull rod 22, and a cam transmission rod 23. The auxiliary plate mounting base 17 is mounted on the rotating end of the nozzle rod assembly 4, and the box-opening auxiliary plate 18 is hinged to the auxiliary plate mounting base 17. The auxiliary rotating sleeve 21 and the auxiliary pull rod 22 are coaxially mounted with the transmission shaft Ⅲ14 of the nozzle rod assembly 4. The swing arm 20 is fixedly connected to the auxiliary rotating sleeve 21. One end of the auxiliary connecting rod 19 is hinged to the auxiliary swing arm 20, and the other end is hinged to the box-opening auxiliary plate 18. The auxiliary rotating sleeve 21 is threadedly engaged with the auxiliary pull rod 22, which converts the axial displacement of the auxiliary pull rod 22 into the axial rotation of the auxiliary rotating sleeve 21. One end of the cam transmission rod 23 is hinged to the auxiliary pull rod 22, and the other end is provided with a roller that engages with the cam groove 25 on the box-opening auxiliary cam disk 16. The box-opening auxiliary cam disk 16 is coaxially assembled with the transmission shaft I8 and fixed on the mounting sleeve 27 of the transmission shaft I8.

[0072] In this embodiment, the box-opening auxiliary mechanism 15 is assembled one-to-one with the suction rod assembly 4. In the initial state, the box-opening auxiliary plate 18 is located on one side of the suction rod assembly 4, and the plane of the box-opening auxiliary plate 18 is parallel to the plane of the suction rod assembly 4 that picks up the flat cardboard box. When the suction rod assembly 4 picks up the cardboard box from the cardboard box storage and revolves to the position of the box-opening assembly 24, it cooperates with the box-opening assembly 24 to open the flat cardboard box into a three-dimensional cardboard box. At the same time as the box-opening assembly 24 cooperates with the suction rod assembly 4, the box-opening auxiliary plate 18 of the box-opening auxiliary mechanism 15 rotates to the position where the plane of the box-opening auxiliary plate 18 is perpendicular to the suction plane of the suction rod assembly 4, and is located on one side of the three-dimensional cardboard box, blocking one side wall of the three-dimensional cardboard box to prevent the three-dimensional cardboard box from reverting to a flat cardboard box or the opening angle from not meeting the material packaging requirements.

[0073] In this embodiment, the box-opening auxiliary cam disk 16, auxiliary plate mounting base 17, box-opening auxiliary plate 18, auxiliary connecting rod 19, auxiliary swing arm 20, auxiliary rotating sleeve 21, auxiliary pull rod 22, and cam transmission rod 23 are connected by the following method: The box-opening auxiliary cam disk 16 is coaxially assembled with the transmission shaft I8 of the nozzle rod assembly 4, and the box-opening auxiliary cam disk 16 is fixed and does not rotate. When the nozzle rod assembly 4 rotates, the box-opening auxiliary mechanism 15 also rotates with the nozzle rod assembly 4, that is, the auxiliary plate mounting base 17, box-opening auxiliary plate 18, auxiliary connecting rod 19, auxiliary swing arm 20, auxiliary rotating sleeve 21, auxiliary pull rod 22, and cam transmission rod 23 all rotate around the box-opening auxiliary cam disk 16.

[0074] One end of the cam drive rod 23 is fitted with a roller in the cam groove 25 of the box-opening auxiliary cam disk 16. As the cam groove 25 moves along its trajectory, when the trajectory of the cam groove 25 changes, the cam drive rod 23 is displaced along the axis of the drive shaft I8. That is, when the cam drive rod 23 moves backward, it drives the auxiliary pull rod 22 to move backward. The auxiliary pull rod 22 moves axially backward, and through the threaded engagement between the auxiliary pull rod 22 and the auxiliary rotating sleeve 21, the backward displacement of the auxiliary pull rod 22 is converted into the rotation of the auxiliary rotating sleeve 21, causing the auxiliary rotating sleeve 21 to rotate. The auxiliary rotating sleeve 21 drives the auxiliary swing arm 20 to swing. The auxiliary swing arm 20 is transmitted through the auxiliary connecting rod 19, causing the box-opening auxiliary plate 18 to rotate around the hinge axis between itself and the auxiliary plate mounting base 17. This causes the box-opening auxiliary plate 18 to rotate from an attitude parallel to the suction plane of the nozzle rod assembly 4 to an attitude perpendicular to the suction plane of the nozzle rod assembly 4.

[0075] Example 7

[0076] As another preferred embodiment of the present invention, this embodiment further supplements and elaborates on the technical solution of the present invention based on the above-described embodiment 6. In this embodiment, the box-opening auxiliary cam plate 16 has an auxiliary pull rod 22 that is pulled outward by a cam transmission rod 23 after the suction rod assembly 4 and the box-opening assembly 24 cooperate to open the flat paper box to form a three-dimensional paper box. After the suction rod assembly 4 releases the three-dimensional paper box onto the box-carrying device, the cam transmission rod 23 resets the cam groove 25 trajectory of the auxiliary pull rod 22. The rotation angle and timing of the box-opening auxiliary plate 18 are controlled by the trajectory of the cam groove 25. After the trajectory of the cam groove 25 is set, the box-opening auxiliary plate 18 can swing to assist in opening the box when the suction rod assembly 4 revolves to a set position.

[0077] Example 8

[0078] As another preferred embodiment of the present invention, this embodiment further supplements and elaborates on the technical solution of the present invention based on the above-described embodiment 6 or embodiment 7. In this embodiment, a connecting ear plate 26 is provided on the box-opening auxiliary plate 18, and the end of the auxiliary connecting rod 19 is hinged to the connecting ear plate 26. Under the transmission of the auxiliary connecting rod 19, the box-opening auxiliary plate 18 swings around its hinge axis with the auxiliary plate mounting base 17 at a set angle. Through the connecting ear plate 26, the force transmitted by the auxiliary connecting rod 19 is better received, so that the box-opening auxiliary plate 18 can swing around its hinge axis with the auxiliary plate mounting base 17 at a set angle. The shape and length of the connecting ear plate 26 can be optimized based on the angle of force transmission and the angle of swing of the box-opening auxiliary plate 18.

[0079] Refer to the instruction manual appendix Figure 6 As shown, the self-rotating drive shaft Ⅲ14 of the nozzle rod assembly 4 has a hollow structure, and the auxiliary rotating sleeve 21 and auxiliary pull rod 22 are disposed within the hollow structure of the drive shaft Ⅲ14. The use of a hollow drive shaft Ⅲ14 allows the box-opening auxiliary mechanism 15 to be integrated with the nozzle rod assembly 4, ensuring that the box-opening auxiliary mechanism 15 effectively follows the movement of the nozzle rod assembly 4, resulting in an optimized structural layout and structural stability.
