By setting the height adjustment driving member 215, the distance between the packaging box placement structure 210 and the first limiting structure 213 can be adjusted, so as to adapt to different specifications of packaging boxes and improve the adaptability of this cartoning machine to different specifications of packaging boxes.

[0058] The box taking assembly includes: a box taking and opening motor 221, a first box taking driving wheel 222, a second box taking driving wheel 223, a box taking lifting frame 224, a box taking swing frame 225, and a swing fixing seat 226.

[0059] The box taking and opening motor 221 is fixedly installed in the maintenance room 110. The output end of the box taking and opening motor 221 is fixedly connected to the first box taking driving wheel 222, and the first box taking driving wheel 222 is in transmission connection with the second box taking driving wheel 223.

[0060] The first cartridge picking driving wheel 222 and the second cartridge picking driving wheel 223 are both rotatably connected to the frame 100.

[0061] The first cartridge picking driving wheel 222 is fixedly connected to the output end of the cartridge picking and opening motor 221. A first fixed connecting rod 227 is fixedly connected to the rotating shaft of the first cartridge picking driving wheel 222. A first swing connecting rod 228 is arranged between the first fixed connecting rod 227 and the cartridge picking lifting frame 224. The two ends of the first swing connecting rod 228 are respectively hinged to the first fixed connecting rod 227 and the cartridge picking lifting frame 224.

[0062] The cartridge picking lifting frame 224 is connected to the frame 100 through a guiding track. The guiding track guides the cartridge picking lifting frame 224 so that the cartridge picking lifting frame 224 moves in the up and down direction. A first cartridge picking suction cup 235 is fixed on the cartridge picking lifting frame 224.

[0063] Both the second cartridge picking driving wheel 223 and the first cartridge picking driving wheel 222 are spur gears. The second cartridge picking driving wheel 223 is meshed and drivingly connected to the first cartridge picking driving wheel 222. A second fixed connecting rod 229 is connected to the rotating shaft of the second cartridge picking driving wheel 223. A second swing connecting rod 230 is arranged between the second fixed connecting rod 229 and the cartridge picking swing frame 225. The two ends of the second swing connecting rod 230 are respectively hinged to the second fixed connecting rod 229 and the cartridge picking swing frame 225.

[0064] The cartridge picking swing frame 225 is rotatably connected to the frame 100.

[0065] The swing fixed seat 226 is fixedly connected to the frame 100. A sliding rotating seat 231 is rotatably connected to the swing fixed seat 226. A sliding swing rod 232 is slidably connected to the sliding rotating seat 231. One end of the sliding swing rod 232 far from the swing fixed seat 226 is fixedly connected to a suction cup rotating shaft 233. The suction cup rotating shaft 233 is rotatably connected to the cartridge picking swing frame 225. A second cartridge picking suction cup 234 is fixedly connected to the suction cup rotating shaft 233.

[0066] When the cartridge picking and opening motor 221 works, it drives the first cartridge picking driving wheel 222 to rotate. Since the second cartridge picking driving wheel 223 is meshed with the first cartridge picking driving wheel 222, the second cartridge picking driving wheel 223 will rotate along with the first cartridge picking driving wheel 222.

[0067] The first cartridge picking driving wheel 222 rotates, driving the cartridge picking lifting frame 224 to move up and down, thereby driving the first cartridge picking suction cup 235 to move upward.

[0068] Meanwhile, the second box picking driving wheel 223 rotates. Through the second fixed connecting rod 229 and the second swing connecting rod 230, the box picking swing frame 225 rotates relative to the frame 100. Due to the swing fixed seat 226, the sliding rotating seat 231, the sliding swing rod 232, and the suction cup rotating shaft 233, the second box picking suction cup 234 moves downward and flips at the same time, so that the second box picking suction cup 234 gradually faces the first box picking suction cup 235.

[0069] Finally, the first box picking suction cup 235 and the second box picking suction cup 234 respectively adsorb the two end faces of the packaging box. Subsequently, the box picking and opening motor 221 continues to work, and the first box picking suction cup 235 and the second box picking suction cup 234 reset, and the packaging box is opened.

[0070] The conveying device 400 includes a second conveying line body and a whole box driving motor 420.

When it is necessary to adjust the distance between two adjacent forward delivery members 414 on the first conveyor component and the second conveyor member, the control system sends a signal to make the two whole-box driving motors 420 generate a speed difference. When the distance between the two forward delivery members 414 is adjusted to the specified distance, the control system sends a signal to make the two whole-box driving motors 420 have the same speed again. By setting like this, the conveying device 400 can be adapted to different specifications of packaging boxes, so as to improve the adaptability of this box loading machine to different specifications of packaging boxes.

[0077] Specifically, in this embodiment, the conveying device 400 further includes a width adjustment mechanism.

[0086] The pressing-down component includes a pressing-down structure and a pressing-down driving member 516. The pressing-down driving member 516 is fixedly installed in the maintenance room 110. The pressing-down driving member 516 is set as a motor. The pressing-down driving member 516 is drivingly connected to a pressing-down driving cam 517 through two meshing gears. The pressing-down driving cam 517 is rotatably connected to the frame 100. The pressing-down driving cam 517 has two cam surfaces, and the two cam surfaces are arranged in the left-right direction.

[0087] The pressing-down structure includes a pressing-down connecting member 511, a pressing-down frame body 512, an inserting connecting rod 513, an inserting swing rod 514, and an inserting frame body 515.

[0088] The middle part of the pressing-down connecting member 511 is rotatably connected to the machine frame 100. A roller structure is rotatably connected to one end of the pressing-down connecting member 511 close to the pressing-down driving cam 517. The roller structure abuts against one of the cam surfaces of the pressing-down driving cam 517. A pressing-down connecting rod is arranged between the other end of the pressing-down connecting member 511 and the pressing-down frame body 512. The two ends of the pressing-down connecting rod are respectively rotatably connected to the pressing-down connecting member 511 and the pressing-down frame body 512. A guiding track is arranged between the pressing-down frame body 512 and the machine frame 100. By arranging the guiding track, the pressing-down frame body 512 can be guided to move in the up-and-down direction.

[0089] One end of the inserting swing rod 514 is hinged to the machine frame 100, and the other end is hinged to the inserting connecting rod 513. A roller structure is rotatably connected to the middle part of the inserting swing rod 514. The roller structure on the inserting swing rod 514 abuts against the cam surface. The roller structure on the inserting swing rod 514 and the roller structure on the pressing-down connecting member 511 respectively abut against the two cam surfaces. An elastic structure is arranged between the inserting swing rod 514 and the machine frame 100. The elastic structure between the inserting swing rod 514 and the machine frame 100 enables the roller structure on the inserting swing rod 514 to always abut against the cam surface. The inserting frame body 515 is hinged to one end of the inserting connecting rod 513 far from the inserting swing rod 514. A guiding track is arranged between the inserting frame body 515 and the pressing-down frame body 512. The guiding track guides the inserting frame body 515 to move in the front-back direction. A inserting plate is fixedly connected to the lower end of the inserting frame body 515. The inserting plate is used to insert into the packaging box to support the upper top surface of the packaging box, so as to prevent the upper top surface of the packaging box from collapsing downward during the box loading process and affecting the normal progress of the box loading work.

[0090] The pushing and box loading assembly includes a pushing structure, a pushing connection structure, and a pushing and box loading driving member 525.

[0091] The pushing structure includes a first pushing frame 521 and a second pushing frame 522. There are guiding rails between the first pushing frame 521 and the second pushing frame 522 and the frame 100. The guiding rails play a guiding role for the first pushing frame 521 and the second pushing frame 522, so that the first pushing frame 521 and the second pushing frame 522 move in the front-back direction. A magnetic attraction member is arranged between the first pushing frame 521 and the second pushing frame 522, and the first pushing frame 521 and the second pushing frame 522 are connected by the magnetic attraction member. A pushing member is connected to the lower end of the second pushing frame 522. When the second pushing frame 522 moves backward, the pushing member pushes the products on the product conveyor line 300 backward to send the products into the packaging box. When the resistance of the pushing member is too large, since the first pushing frame 521 and the second pushing frame 522 are connected by magnetic force, the first pushing frame 521 and the second pushing frame 522 will separate, thus preventing the pushing member from continuing to push into the products and causing damage to the packaging box or the products.

[0092] The pushing and box-loading driving member 525 is installed in the maintenance room 110 or on the side wall of the frame 100 close to the maintenance room 110. Specifically, in this embodiment, the pushing and box-loading driving member 525 is fixedly installed on one side of the frame 100 close to the maintenance room 110. In other embodiments, the pushing and box-loading driving member 525 can also be fixedly installed in the maintenance room 110, and those skilled in the art can select the installation position of the pushing and box-loading driving member 525 according to actual needs.

[0093] The pushing connection structure includes a pushing connecting member 523 and a pushing connecting rod 524. One end of the pushing connecting member 523 is fixed to the output end of the pushing and box-loading driving member 525, and the other end is hinged to the pushing connecting rod 524. The end of the pushing connecting rod 524 far from the pushing connecting member 523 is rotatably connected to the first pushing frame 521.

[0094] In this solution, most of the driving structures such as the box-taking and box-opening motor 221, the product conveying motor 320, and the whole-box driving motor 420 are installed in the maintenance room 110. Compared with the structure in the prior art where the motors of the box-taking and box-opening mechanism 200, the product conveyor line 300, the conveying device 400 and other structures are scattered in the box-packing machine, it can effectively prevent the packaging box or the products from colliding with the box-taking and box-opening motor 221, the product conveying motor 320, and the whole-box driving motor 420 when they fall, thus effectively protecting the box-taking and box-opening motor 221, the product conveying motor 320, and the whole-box driving motor 420, and extending the service life of the driving members such as the box-taking and box-opening motor 221, the product conveying motor 320, and the whole-box driving motor 420. Moreover, installing the driving structures such as the box-taking and box-opening motor 221, the product conveying motor 320, and the whole-box driving motor 420 in the maintenance room 110 will not be blocked by other components during maintenance, which is convenient for the staff to find the motors and does not hinder the maintenance operation, thus effectively reducing the difficulty of maintenance for the staff.
