Description

Technical Field

[0001] The invention relates to a carton opening device, in particular to a carton full-automatic opening and bottom sealing device. Background Art

[0002] Carton packaging is one of the most common packaging methods for commodities. Existing cartons are usually folded when not in use to save space. When using a carton, it is first necessary to unpack it, that is, to unfold the folded carton into a square to accommodate the object.

[0003] Currently, the industry mostly relies on manual unpacking of folded cartons, followed by sealing the bottom of the cartons with a bottom-sealing device or by manually applying transparent tape to create finished cartons ready for product loading. However, this unpacking method not only requires more labor, but is also time-consuming and labor-intensive, impacting production efficiency. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above-mentioned problems and provide a fully automatic carton opening and bottom sealing device, which can automatically complete the unpacking and bottom sealing operations without manual participation, saving time and effort and greatly improving work efficiency.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] A fully automatic carton opening and bottom sealing device comprises a loading platform for placing folded cartons, an opening mechanism for transporting and opening the cartons, a bending mechanism for bending the bottom of the cartons, and a sealing mechanism for applying adhesive tape to the bottom of the cartons.

[0007] The unpacking mechanism includes an unpacking robot and an unpacking fixture. The unpacking fixture is arranged on the end joint of the unpacking robot. The unpacking fixture includes a first fixture assembly, a second fixture assembly, and a flipping drive mechanism for driving the second fixture assembly to flip. The first fixture assembly and the second fixture assembly are respectively used to grasp two adjacent sides of the carton.

[0008] The bending mechanism includes an X-direction bending mechanism and a Y-direction bending mechanism, the X-direction bending mechanism includes a bending guide plate; the Y-direction bending mechanism includes a Y-direction bending piece and a Y-direction bending drive mechanism, and the Y-direction bending piece is provided with two pieces and is used to bend the two bottom sheets of the carton in the Y direction respectively.

[0009] In a preferred embodiment of the present invention, the first fixture assembly includes a first fixture mounting plate and a first fixture suction cup;

[0010] The second clamp assembly includes a second clamp mounting plate and a second clamp suction cup, and the second clamp mounting plate is hinged to the first clamp mounting plate via a hinge.

[0011] Furthermore, the flip driving mechanism includes a flip driving cylinder, a cylinder body of the flip driving cylinder is hinged on the first fixture mounting plate, and a telescopic rod of the flip driving cylinder is hinged on the second fixture mounting plate.

[0012] With the above structure, under the drive of the flip driving cylinder, the second clamp mounting plate can be flipped relative to the first clamp mounting plate around the loose-leaf piece, thereby opening the carton.

[0013] In a preferred embodiment of the present invention, the bending guide plate includes a horizontal guide section and an arc-shaped guide section, the horizontal guide section is located between the arc-shaped guide section and the sealing mechanism, and the arc-shaped guide section extends upward.

[0014] In a preferred embodiment of the present invention, the Y-direction bending member is a Y-direction bending push rod;

[0015] The Y-direction bending drive mechanism includes two Y-direction bending drive cylinders, each fixedly connected to a pair of Y-direction bending push rods. The two Y-direction bending drive cylinders are driven in opposite directions. With this structure, the two Y-direction bending push rods can push the two Y-direction bottom sheets of the carton in opposite directions under the drive of the Y-direction bending drive cylinders, thereby bending the two Y-direction bottom sheets of the carton.

[0016] In a preferred embodiment of the present invention, a bottom support mechanism is provided between the bending mechanism and the sealing mechanism. The bottom support mechanism includes a bottom support plate and a bottom support lift drive cylinder, the telescopic rod of the bottom support lift drive cylinder being fixedly connected to the bottom support plate. In this way, the bottom of the carton can be supported during the transfer of the carton from the bending mechanism to the sealing mechanism, so that the bottom sheet of the carton remains in a 90-degree bent position, facilitating subsequent sealing.

[0017] In a preferred embodiment of the present invention, the unpacking mechanism further comprises an auxiliary mechanism, which comprises an auxiliary clamp and a clamp driving mechanism for driving the auxiliary clamp to move.

[0018] The structure of the auxiliary fixture is the same as that of the unpacking fixture;

[0019] The clamp drive mechanism includes an auxiliary rotation drive mechanism for driving the auxiliary clamp to rotate, an auxiliary X-direction drive mechanism for driving the auxiliary clamp to move in the X direction, an auxiliary Y-direction drive mechanism for driving the auxiliary clamp to move in the Y direction, and an auxiliary Z-direction drive mechanism for driving the auxiliary clamp to move in the Z direction. The rotation plane of the auxiliary rotation drive mechanism is parallel to the XZ plane. Through the above structure, the auxiliary clamp can grasp the other two adjacent sides of the carton, so that all four sides of the carton are grasped, and then the four sides of the carton can be actively controlled to open the carton. The carton can be opened in place to obtain a regular rectangular carton, avoiding the phenomenon of individual sides of the carton being skewed, and ensuring the quality of the carton after opening.

[0020] Furthermore, the auxiliary rotation drive mechanism is arranged on the auxiliary Z-direction drive mechanism, the auxiliary Z-direction drive mechanism is arranged on the auxiliary Y-direction drive mechanism, and the auxiliary Y-direction drive mechanism is arranged on the auxiliary X-direction drive mechanism.

[0021] Furthermore, the auxiliary rotation drive mechanism includes an auxiliary rotation drive motor, the output shaft of which is connected to the auxiliary clamp. Through the above structure, the auxiliary clamp can be rotated under the drive of the auxiliary rotation drive motor, thereby cooperating with the unpacking clamp to tilt the carton.

[0022] Furthermore, the auxiliary Z-drive mechanism includes an auxiliary Z-drive motor, an auxiliary Z-drive assembly, and an auxiliary Z-movable plate. The auxiliary Z-drive assembly includes an auxiliary Z-drive screw and an auxiliary Z-drive screw nut, and the auxiliary Z-movable plate is fixedly connected to the auxiliary Z-drive screw nut. With this structure, the auxiliary Z-drive motor drives the auxiliary fixture to move upward and downward, thereby pressing the carton against the bending guide plate to achieve bottom bending.

[0023] Furthermore, the auxiliary Y-axis drive mechanism includes an auxiliary Y-axis drive motor, an auxiliary Y-axis transmission assembly, and an auxiliary Y-axis movable base. The auxiliary Y-axis transmission assembly includes an auxiliary Y-axis drive screw and an auxiliary Y-axis drive screw nut, and the auxiliary Y-axis movable base is fixedly connected to the auxiliary Y-axis drive screw nut. With this structure, the auxiliary Y-axis drive motor can drive the auxiliary fixture to move in the Y direction, accommodating cartons of different sizes.

[0024] Furthermore, the auxiliary X-axis drive mechanism includes an auxiliary X-axis drive motor, an auxiliary X-axis transmission assembly, and an auxiliary X-axis movable plate. The auxiliary X-axis transmission assembly includes an auxiliary X-axis transmission screw and an auxiliary X-axis transmission screw nut, and the auxiliary X-axis movable plate is fixedly connected to the auxiliary X-axis transmission screw nut. With this structure, the auxiliary X-axis drive motor drives the auxiliary fixture to move in the X direction, thereby completing the X-axis film bending operation.

[0025] In a preferred embodiment of the present invention, the bending guide plate includes a front guide plate, a rear guide plate, and a rear guide driving mechanism for driving the rear guide plate to swing, wherein the front guide plate is located between the rear guide plate and the sealing mechanism, and the length of the rear guide plate is greater than the length of the bottom film in the X direction of the carton; before bending, the front guide plate and the rear guide plate are both in an inclined state; after bending, the rear guide plate supports the bottom film in the X direction of the carton near the sealing mechanism. Through the above structure, when the carton moves downward and approaches the bending guide plate, the two bottom films in the X direction of the carton bottom touch the inclined front guide plate and the rear guide plate respectively, and then automatically bend inward; after bending to a certain angle, the rear guide plate is driven by the rear guide driving mechanism to swing upward, first pushing its corresponding bottom film to continue to flip upward, and because the length of the rear guide plate is greater than the length of the bottom film in the X direction of the carton, the rear guide plate also pushes the other bottom film to bend upward until the bottom film is bent 90 degrees.

[0026] Furthermore, the rear guide drive mechanism includes a swing arm, a downward pressure transmission structure, and the auxiliary Z-direction drive mechanism. One end of the swing arm is connected to the rear guide plate through a first rotating shaft, and the swing arm is located below the downward pressure transmission structure. The bottom of the downward pressure transmission structure is supported on the other end of the swing arm. A vertical guide structure is provided between the downward pressure transmission structure and the auxiliary Y-direction moving seat. A downward pressure rod is provided on the auxiliary Z-direction moving plate, and the downward pressure rod is located above the downward pressure transmission structure. Through the above structure, when the auxiliary Z-direction drive mechanism drives the auxiliary clamp to move the carton downward, the downward pressure rod on the auxiliary Z-direction moving plate also moves downward toward the downward pressure transmission structure. After the two bottom sheets in the X direction at the bottom of the carton are automatically bent at a certain angle, the downward pressure rod presses on the downward pressure transmission structure and drives the downward pressure transmission structure to move downward. The downward pressure transmission structure drives the swing arm to swing downward, causing the rear guide plate to swing upward, completing the bending of the bottom sheet.

[0027] Furthermore, the first rotating shaft is rotatably connected to the bending frame, and the bending frame is provided with a first limiting portion and a second limiting portion. The first limiting portion is used to limit the rear guide plate from swinging downward so that the rear guide plate maintains a specified inclination angle before bending; the first limiting portion is used to limit the rear guide plate from swinging upward when the rear guide plate swings to a horizontal state.

[0028] Furthermore, the top of the front guide plate is lower than the rear guide plate in a horizontal state so as not to block the carton from being conveyed to the glue sealing mechanism.

[0029] Furthermore, the front guide plate is provided with an arc surface to better guide the bottom film to bend.

[0030] Furthermore, the Y-direction bending member is a Y-direction bending flap, and the two Y-direction bending flaps are synchronously flipped through a synchronous transmission assembly;

[0031] The Y-direction bending drive mechanism includes a swing plate, the downward pressing transmission structure and the auxiliary Z-direction drive mechanism; the swing plate is fixedly connected to the Y-direction bending flap via a second rotating shaft;

[0032] The cam is connected to the auxiliary Y-axis moving seat through the vertical guide structure, and the first lower pressure frame is provided with a mounting clamp; the first lower pressure frame is provided with a lower pressure plate for pressing the swing plate; the second lower pressure frame can be vertically slidably connected to the first lower pressure frame, and the second lower pressure frame is provided with a column and two cross beams. The cross beam at the top is located in the mounting clamp, and the cross beam at the bottom is used to support the roller at the other end of the swing arm; the secondary lower pressure spring is located in the mounting clamp and is sleeved on the column of the second lower pressure frame. The upper end of the secondary lower pressure spring is tightly pressed against the upper bottom surface of the mounting clamp, and the lower end of the secondary lower pressure spring is tightly pressed against the cross beam located above the second lower pressure frame;

[0033] During the bending operation, the second lower pressing frame first presses down on the swing arm, and then the lower pressing plate on the first lower pressing frame presses down on the swing plate.

[0034] Through the above structure, when the auxiliary Z-direction driving mechanism drives the auxiliary clamp to move the carton downward, the downward pressure rod on the auxiliary Z-direction moving plate also moves downward close to the first downward pressure frame, and the first downward pressure frame transmits power to the second downward pressure frame through the secondary downward pressure spring, and then the second downward pressure frame pushes the swing arm downward, causing the rear guide plate to swing upward, thereby bending the bottom film in the X direction; after the rear guide plate swings a certain angle, the lower pressure plate on the first lower pressure frame presses down on the swing plate, causing the Y-direction bending flap in the vertical state to start swinging upward, thereby bending the bottom film in the Y direction; When the rear guide plate swings to a horizontal state, the second limiter limits the rear guide plate to prevent it from continuing to swing upward; the auxiliary Z-direction drive mechanism continues to drive downward, and since the rear guide plate and the second lower pressure frame remain stationary, it then begins to compress the secondary downward pressure spring, exchanging space for the first lower pressure frame to continue to move downward, until the Y-direction bending flap completes the bending of the Y-direction bottom film; at this time, the X-direction bottom film and the Y-direction bottom film are both bent to form the bottom of the carton. Maintaining this state, the carton is transported downward to the sealing mechanism, which seals the bottom of the carton with glue. Furthermore, in the above operation, the bending power of the X-direction bottom film and the Y-direction bottom film comes from the auxiliary Z-direction drive mechanism, so there is no need to set up an additional drive mechanism, which can greatly simplify the structure and reduce costs.

[0035] Furthermore, the synchronous transmission assembly includes multiple sets of synchronous belt assemblies.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. The box opening and bottom sealing equipment of the present invention can automatically complete the box opening and bottom sealing operations by providing the box opening mechanism and the bending mechanism, without manual participation, saving time and labor and greatly improving work efficiency.

[0038] 2. By setting up the bending guide plate, the bending work of the two bottom sheets in the X direction of the carton can be completed without additional power: first, the horizontal guide section of the bending guide plate bends the bottom sheet in the X direction of the carton close to the sealing mechanism, and then the horizontal guide section of the bending guide plate bends the other bottom sheet in the X direction of the carton. The structure is simple and the operation is easy. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described below in conjunction with embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0048] Example 1

[0049] Combine Figure 1The fully automatic carton opening and bottom sealing equipment of this embodiment includes a loading platform 1 for placing folded cartons, an opening mechanism for transporting and opening the cartons, a bending mechanism for bending the bottom of the carton, and a sealing mechanism 2 for applying tape to the bottom of the carton. The sealing mechanism 2 can adopt a ready-made structure.

[0050] Combine Figure 1-Figure 2 The unpacking mechanism includes an unpacking robot 3 and an unpacking clamp. The unpacking clamp is arranged on the end joint of the unpacking robot 3. The unpacking clamp includes a first clamp assembly, a second clamp assembly and a flipping drive mechanism for driving the second clamp assembly to flip. The first clamp assembly and the second clamp assembly are respectively used to grasp two adjacent sides of the carton; wherein, the first clamp assembly includes a first clamp mounting plate 4 and a first clamp suction cup 5; the second clamp assembly includes a second clamp mounting plate 6 and a second clamp suction cup 7, and the second clamp mounting plate 6 is hinged to the first clamp mounting plate 4 through a loose-leaf piece.

[0051] Furthermore, the flip driving mechanism includes a flip driving cylinder 8 , a cylinder body of the flip driving cylinder 8 is hinged on the first fixture mounting plate 4 , and a telescopic rod of the flip driving cylinder 8 is hinged to the second fixture mounting plate 6 .

[0052] With the above structure, driven by the flip driving cylinder 8, the second clamp mounting plate 6 can flip around the loose-leaf piece relative to the first clamp mounting plate 4, thereby opening the carton.

[0053] Combine Figure 1 and Figure 3 The bending mechanism includes an X-direction bending mechanism and a Y-direction bending mechanism, and the X-direction bending mechanism includes a bending guide plate; wherein, the bending guide plate includes a horizontal guide section 9 and an arc-shaped guide section 10, and the horizontal guide section 9 is located between the arc-shaped guide section 10 and the sealing mechanism 2, and the arc-shaped guide section 10 extends upward.

[0054] Combine Figure 1 and Figure 3 The Y-direction bending mechanism includes two Y-direction bending members and a Y-direction bending drive mechanism. The Y-direction bending members are Y-direction bending push rods 11, each for bending the two bottom sheets of the carton in the Y direction. The Y-direction bending drive mechanism includes two Y-direction bending drive cylinders 12, each fixedly connected to the two Y-direction bending push rods 11. The two Y-direction bending drive cylinders 12 drive in opposite directions. Through this structure, under the drive of the Y-direction bending drive cylinders 12, the two Y-direction bending push rods 11 can push the two bottom sheets of the carton in the Y direction toward each other, thereby achieving bending of the two bottom sheets of the carton in the Y direction.

[0055] Combine Figure 3A bottom supporting mechanism is provided between the bending mechanism and the sealing mechanism 2. The bottom supporting mechanism includes a bottom supporting plate 13 and a bottom supporting lifting drive cylinder 14. The telescopic rod of the bottom supporting lifting drive cylinder 14 is fixedly connected to the bottom supporting plate 13. In this way, the bottom of the carton can be supported during the transfer of the carton from the bending mechanism to the sealing mechanism 2, so that the bottom sheet of the carton can be kept in a 90-degree bent posture for subsequent sealing.

[0056] Combine Figure 1-Figure 3 The working principle of the above-mentioned fully automatic carton opening and bottom sealing equipment is as follows:

[0057] During operation, the folded carton is first placed on the loading platform 1, and the unpacking clamp is driven by the unpacking robot 3 to approach the carton on the loading platform 1. At this time, the first clamp assembly and the second clamp assembly are arranged in the same straight line, and then the two adjacent sides of the carton are grasped respectively.

[0058] The unpacking robot 3 drives the unpacking fixture and the carton to move toward the bending guide plate, and turns the carton to an inclined state, so that the bottom film of the carton in the X direction close to the sealing mechanism 2 is located at the bottom; at the same time, the flip drive mechanism drives the second clamp assembly to flip relative to the first clamp assembly, and the side of the carton undergoes a chain action, thereby gradually stretching the flat carton until the angle between the second clamp assembly and the first clamp assembly is 90 degrees. At this time, the carton has a rectangular structure, and the bottom and top of the carton are both in a straight state.

[0059] When the carton approaches the bending guide plate, the bottom film in the X direction at the bottom of the carton close to the sealing mechanism 2 is tilted downward and pressed against the horizontal guide section 9 of the bending guide plate, so that the bottom film is bent toward the inner cavity of the carton; then, the unpacking robot 3 drives the carton to move in the direction of the arc-shaped guide section 10 of the bending guide plate, so that the other bottom film in the X direction at the bottom of the carton is pressed against the arc-shaped guide section 10, and the arc-shaped guide section 10 prompts the bottom film to be bent toward the inner cavity of the carton; then, the unpacking robot 3 moves the carton to the top of the horizontal guide section 9 of the bending guide plate and straightens the carton. At this time, the two bottom films in the X direction of the carton are both bent; at this time, the two bottom films in the Y direction of the carton extend on both sides below the bending guide plate.

[0060] The two Y-direction bending push rods 11 are driven by the Y-direction bending drive mechanism to move toward each other, and the two bottom sheets of the carton in the Y direction are bent respectively; after the bending is completed, the current state is maintained and the carton is transported to the sealing mechanism 2, and the sealing mechanism 2 seals the bottom of the carton to fix the bottom of the carton.

[0061] Example 2

[0062] Unlike Example 1, the unpacking mechanism of this embodiment further includes an auxiliary mechanism, which includes an auxiliary clamp and a clamp driving mechanism for driving the auxiliary clamp to move. The structure of the auxiliary clamp is the same as that of the unpacking clamp. The clamp driving mechanism includes an auxiliary rotation driving mechanism for driving the auxiliary clamp to rotate, an auxiliary X-direction driving mechanism for driving the auxiliary clamp to move in the X direction, an auxiliary Y-direction driving mechanism for driving the auxiliary clamp to move in the Y direction, and an auxiliary Z-direction driving mechanism for driving the auxiliary clamp to move in the Z direction. The rotation plane of the auxiliary rotation driving mechanism is parallel to the XZ plane. Through the above structure, the auxiliary clamp can grasp the other two adjacent sides of the carton, so that all four sides of the carton are grasped, and then the four sides of the carton can be actively controlled to perform the opening operation. The carton can be opened in place to obtain a regular rectangular carton, avoiding the phenomenon of individual sides of the carton being skewed, thereby ensuring the quality of the carton after unpacking.

[0063] Combine Figure 4 and Figure 5 The auxiliary rotation drive mechanism is arranged on the auxiliary Z-direction drive mechanism, the auxiliary Z-direction drive mechanism is arranged on the auxiliary Y-direction drive mechanism, and the auxiliary Y-direction drive mechanism is arranged on the auxiliary X-direction drive mechanism.

[0064] Combine Figure 4 and Figure 5 The auxiliary rotation drive mechanism includes an auxiliary rotation drive motor 15, the output shaft of which is connected to the auxiliary clamp. Through the above structure, the auxiliary clamp can be rotated under the drive of the auxiliary rotation drive motor 15, thereby cooperating with the unpacking clamp to tilt the carton.

[0065] Combine Figure 4 and Figure 5 The auxiliary Z-drive mechanism includes an auxiliary Z-drive motor 16, an auxiliary Z-drive assembly, and an auxiliary Z-moving plate 17. The auxiliary Z-drive assembly includes an auxiliary Z-drive screw and an auxiliary Z-drive screw nut. The auxiliary Z-moving plate 17 is fixedly connected to the auxiliary Z-drive screw nut. This structure enables the auxiliary Z-drive motor 16 to drive the auxiliary fixture to move upward and downward, thereby pressing the carton against the bending guide plate to achieve bottom bending.

[0066] Combine Figure 4 and Figure 5The auxiliary Y-drive mechanism includes an auxiliary Y-drive motor 18, an auxiliary Y-drive assembly, and an auxiliary Y-moving base 19. The auxiliary Y-drive assembly includes an auxiliary Y-drive screw and an auxiliary Y-drive screw nut. The auxiliary Y-moving base 19 is fixedly connected to the auxiliary Y-drive screw nut. This structure enables the auxiliary Y-drive motor 18 to drive the auxiliary fixture to move in the Y direction, accommodating cartons of varying sizes.

[0067] Combine Figure 4 and Figure 5 The auxiliary X-axis drive mechanism includes an auxiliary X-axis drive motor 20, an auxiliary X-axis transmission assembly, and an auxiliary X-axis movable plate 21. The auxiliary X-axis transmission assembly includes an auxiliary X-axis drive screw and an auxiliary X-axis drive screw nut. The auxiliary X-axis movable plate 21 is fixedly connected to the auxiliary X-axis drive screw nut. With this structure, the auxiliary X-axis drive motor 20 drives the auxiliary fixture to move in the X direction, thereby completing the X-axis film bending operation.

[0068] Combine Figure 4-Figure 6 The bending guide plate includes a front guide plate 22, a rear guide plate 23, and a rear guide driving mechanism for driving the rear guide plate 23 to swing. The front guide plate 22 is located between the rear guide plate 23 and the sealing mechanism 2. The length of the rear guide plate 23 is greater than the length of the bottom film of the carton in the X direction. Before bending, the front guide plate 22 and the rear guide plate 23 are both in an inclined state. After bending, the rear guide plate 23 supports the bottom film of the carton in the X direction near the sealing mechanism 2. Through the above structure, when the carton moves downward and approaches the bending guide plate, the two bottom films in the X direction at the bottom of the carton touch the inclined front guide plate 22 and the rear guide plate 23 respectively, and then automatically bend inward. After bending to a certain angle, the rear guide driving mechanism drives the rear guide plate 23 to swing upward, first pushing its corresponding bottom film to continue to flip upward. Since the length of the rear guide plate 23 is greater than the length of the bottom film of the carton in the X direction, the rear guide plate 23 also pushes the other bottom film to bend upward until the bottom film is bent 90 degrees.

[0069] Combine Figure 4-Figure 6The rear guide drive mechanism includes a swing arm 24, a downward pressure transmission structure, and the auxiliary Z-direction drive mechanism. One end of the swing arm 24 is connected to the rear guide plate 23 through a first rotating shaft 25. The swing arm 24 is located below the downward pressure transmission structure. The bottom of the downward pressure transmission structure is supported on the other end of the swing arm 24. A vertical guide structure is provided between the downward pressure transmission structure and the auxiliary Y-direction moving seat 19. The auxiliary Z-direction moving plate 17 is provided with a downward pressure rod 26, which is located above the downward pressure transmission structure. Through the above structure, when the auxiliary Z-direction drive mechanism drives the auxiliary clamp to move the carton downward, the downward pressure rod 26 on the auxiliary Z-direction moving plate 17 also moves downward toward the downward pressure transmission structure. After the two bottom sheets in the X direction at the bottom of the carton are automatically bent at a certain angle, the downward pressure rod 26 presses on the downward pressure transmission structure and drives the downward pressure transmission structure to move downward. The downward pressure transmission structure drives the swing arm 24 to swing downward, causing the rear guide plate 23 to swing upward, completing the bending of the bottom sheets.

[0070] Furthermore, the top of the front guide plate 22 is lower than the rear guide plate 23 in a horizontal state so as not to block the carton from being transported to the glue sealing mechanism 2 .

[0071] Furthermore, the front guide plate 22 is provided with an arc surface to better guide the bottom sheet to bend.

[0072] Combine Figure 9 The first rotating shaft 25 is rotatably connected to the bending frame 27, and the bending frame 27 is provided with a first limiting portion 27-1 and a second limiting portion 27-2. The first limiting portion 27-1 is used to limit the rear guide plate 23 from swinging downward so that the rear guide plate 23 maintains a specified inclination angle before bending; the first limiting portion 27-1 is used to limit the rear guide plate 23 from swinging upward when the rear guide plate 23 swings to a horizontal state.

[0073] Combine Figure 6-Figure 9The Y-direction bending part is a Y-direction bending flap 28, and the two Y-direction bending flaps 28 are synchronously flipped through a synchronous transmission component; the Y-direction bending drive mechanism includes a swing plate 29, the downward pressure transmission structure and the auxiliary Z-direction drive mechanism; the swing plate 29 is fixedly connected to the Y-direction bending flap 28 through a second rotating shaft 34; the downward pressure transmission structure includes a first downward pressure frame 30, a second downward pressure frame 31 and a secondary downward pressure spring 32, the first downward pressure frame 30 is connected to the auxiliary Y-direction moving seat 19 through the vertical guide structure, and the first downward pressure frame 30 is provided with an installation position; the first downward pressure frame 30 is provided with a The lower pressure plate 33 on the swing plate 29; the second lower pressure frame 31 can be vertically slidably connected to the first lower pressure frame 30, and the second lower pressure frame 31 is provided with a column and two cross beams, the upper cross beam is located in the installation position, and the lower cross beam is used to support the roller at the other end of the swing arm 24 (the length of this cross beam is longer so that it can still remain supported on the roller during lateral movement); the secondary downward pressure spring 32 is located in the installation position and is mounted on the column of the second lower pressure frame 31, the upper end of the secondary downward pressure spring 32 is pressed against the upper bottom surface of the installation position, and the lower end of the secondary downward pressure spring 32 is pressed against the cross beam located above the second lower pressure frame 31.

[0074] During the bending operation, the second lower pressing frame 31 first presses down on the swing arm 24 , and then the lower pressing plate 33 on the first lower pressing frame 30 presses down on the swing plate 29 .

[0075] When the auxiliary Z-direction driving mechanism drives the auxiliary clamp to move the carton downward, the lower pressure rod 26 on the auxiliary Z-direction moving plate 17 also moves downward and approaches the first lower pressure frame 30. The first lower pressure frame 30 transmits the power to the second lower pressure frame 31 through the secondary lower pressure spring 32. Then, the second lower pressure frame 31 pushes the swing arm 24 downward, causing the rear guide plate 23 to swing upward, thereby bending the film in the X direction; after the rear guide plate 23 swings to a certain angle, the lower pressure plate 33 on the first lower pressure frame 30 presses down on the swing plate 29, causing the Y-direction bending flap 28 in the vertical state to start swinging upward, thereby bending the film in the Y direction; when the rear guide plate 23 swings to a horizontal state, as shown in FIG. Figure 7 The second limiting portion 27-2 limits the rear guide plate 23 to prevent the rear guide plate 23 from continuing to swing upward; the auxiliary Z-direction driving mechanism continues to drive downward, and since the rear guide plate 23 and the second lower pressing frame 31 remain stationary, the secondary pressing spring 32 begins to be compressed, in exchange for the space for the first lower pressing frame 30 to continue to move downward, until the Y-direction bending flap 28 completes the bending work of the film in the Y direction, as shown in FIG. Figure 8At this point, the X- and Y-direction bottom sheets are both bent to form the bottom of the carton. Maintaining this state, the carton is conveyed downward to the gluing mechanism 2, which then performs the gluing. Furthermore, in the above operation, the bending power for the X- and Y-direction bottom sheets is derived from the auxiliary Z-direction drive mechanism, eliminating the need for an additional drive mechanism, significantly simplifying the structure and reducing costs.

[0076] Furthermore, the synchronous transmission assembly includes multiple sets of synchronous belt assemblies, and the specific structure can refer to the existing technology.

[0077] The above is a preferred embodiment of the present invention, but the embodiment of the present invention is not limited to the above content. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
