Specific implementation mode

[0017] The present utility model can be explained in detail through the following embodiments. The purpose of disclosing the present utility model is to protect all technical improvements within the scope of the present utility model.

[0018] Please refer to Figures 1-3 , this embodiment provides a technical solution: a box nailing device for packaging box processing, including a frame 1 and a nail box 10. An insert nail plate 9 is detachably arranged inside the nail box 10. An electric hydraulic push rod 7 is installed on the bracket of the frame 1. A pressing plate 8 is fixed at the telescopic end of the electric hydraulic push rod 7. A plurality of connecting frames 11 are rotatably connected to the top of the frame 1 through a rotating shaft 2. The top of the connecting frame 11 is connected to the nail box 10 through a reset mechanism 6. And a driving mechanism 3 for driving the rotating shaft 2 to rotate is installed on the top of the frame 1. A nail box auxiliary mechanism 4 for assisting the nail box 10 to reset is installed on the top of the frame 1. A PLC controller 12 is installed on the side surface between the frames 1. The PLC controller 12 is electrically connected to an external power supply. The electric hydraulic push rod 7 is electrically connected to the PLC controller 12. The telescopic end of the electric hydraulic push rod 7 drives the pressing plate 8 to move up and down. The pressing plate 8 hammers the screws inserted on the nail pad of the insert nail plate 9, so as to nail the screws on the nail pad into the packaging box. Its hammering method is the same as that in the patent with the authorized publication number of CN212399865U. After the box nailing is completed, the pressing plate 8 returns to its original position.

[0019] The driving mechanism 3 includes a worm gear 31, a servo motor 32 and a worm 33. The worm gear 31 is sleeved and fixed on the rotating shaft 2. The servo motor 32 is installed on the side of the top support of the frame 1. The worm 33 is fixed on the output shaft of the servo motor 32. And the worm 33 meshes with the worm gear 31. The servo motor 32 is electrically connected to the PLC controller 12. The output shaft of the servo motor 32 drives the worm 33 to rotate. The worm 33 and the worm gear 31 are engaged and transmitted. The worm gear 31 drives the connecting frame 11 to rotate through the rotating shaft 2, so as to move the insert nail plate 9 under the pressing plate 8. Its operation is convenient, avoiding the trouble of frequently pulling and pushing the rack for feeding. At the same time, there are multiple insert nail plates 9, ensuring that the stock preparation operation and the box nailing operation can be carried out simultaneously, thus improving the processing efficiency, and it will not affect the stock preparation operation on the remaining nail boxes 10 during the box nailing process.

[0020] The reset mechanism 6 includes a sliding seat 61, a limit block 62, a spring 63 and a live rod 64. The live rod 64 is fixed to the top of the connecting frame 11, the limit block 62 is fixed to the top of the live rod 64, the sliding seat 61 is fixed to the side of the nail box 10 and is slidably connected to the live rod 64 up and down. The spring 63 is sleeved on the live rod 64 and is arranged between the sliding seat 61 and the connecting frame 11. After the nail box is completed, the pressing plate 8 returns to its original position, and the compressed spring 63 restores its deformation. The deformation force of the spring 63 acts on the sliding seat 61 in the opposite direction, and the sliding seat 61 and the live rod 64 slide relative to each other, so that the nail box 10 returns to its original position. When it returns to its original position, the screws on the nail inserting plate 9 are separated from the nail pads, which avoids the trouble of manual separation, saving time and effort.

[0021] The nail box auxiliary mechanism 4 includes a telescopic rod 41 and a connecting seat 42. The telescopic rod 41 is installed on the top of the machine frame 1, and the connecting seat 42 is fixed to the telescopic end of the telescopic rod 41. The nail box auxiliary mechanism 4 further includes an electric push rod 43, a socket 44 and a plug 45. The electric push rod 43 is installed on the side of the connecting seat 42, the socket 44 is fixed to the telescopic end of the electric push rod 43, and the plug 45 is fixed to the side of the nail box 10, and the plug 45 is inserted into the socket 44 in a matching manner. The electric push rod 43 is electrically connected to the PLC controller 12. The telescopic end of the electric push rod 43 drives the socket 44 to approach the plug 45, so that the plug 45 on the nail box 10 is inserted into the socket 44 in a matching manner, thereby supporting the side of the nail box 10. When the nail box 10 moves up and down, the connecting seat 42 drives the telescopic rod 41 to expand and contract. By supporting the side of the nail box 10, the nail box operation can be ensured to proceed normally. After the nail box is completed, the socket 44 returns to its original position, and then the nail box operation for the next packaging box is carried out.

[0022] It further includes a positioning frame 5. The positioning frame 5 is fixed to the top of the machine frame 1. The positioning frame 5 is a "U" - shaped frame. The packaging box is placed in the positioning frame 5. Through positioning, it is avoided that the placement position of the packaging box is improper, resulting in the dislocation of the nail box position, thus ensuring the processing quality.

[0023] The working principle of a carton nailing device for processing the utility model is as follows: Place the carton in the positioning frame 5. The output shaft of the servo motor 32 drives the worm 33 to rotate. The worm 33 is in meshing transmission with the worm wheel 31. The worm wheel 31 drives the connecting frame 11 to rotate through the rotating shaft 2, so as to move the nail inserting plate 9 below the pressing plate 8. Then, the telescopic end of the electric push rod 43 drives the socket 44 to approach the plug 45, so that the plug 45 on the nail box 10 is inserted and matched with the socket 44, so as to support the side of the nail box 10. Then, the telescopic end of the electro-hydraulic push rod 7 drives the pressing plate 8 to move up and down. The pressing plate 8 hammers the screws inserted on the nail pads of the nail inserting plate 9, so as to nail the screws on the nail pads into the carton. The hammering method is the same as that in the patent with the authorization publication number CN 212399865 U. After the carton nailing is completed, the pressing plate 8 returns to its original position, and the compressed spring 63 restores its deformation. The deformation force of the spring 63 acts on the sliding seat 61 in the opposite direction. The sliding seat 61 and the live rod 64 slide relative to each other, so that the nail box 10 returns to its original position. When it returns to its original position, the screws on the nail inserting plate 9 are separated from the nail pads. When the nail box 10 moves up and down, the connecting seat 42 drives the telescopic rod 41 to expand and contract. After the carton nailing is completed, the socket 44 returns to its original position, and then the nailing operation of the next carton is carried out.
