Taking a single upper film component as an example, the structure of the upper film component is introduced as follows. The upper film component includes a mounting frame 5, a plurality of material rollers 10 (a packaging film roll is sleeved on the outer wall of the material roller 10), a detector 11, and a hot pressing mechanism 9 (such as a heat sealer); in this application, taking two material rollers 10 in each upper film component as an example, the mounting frame 5 and the material rollers 10 are both installed on the frame 1, the mounting frame 5 is located above the material rollers 10, there are two detectors 11, the detector 11 refers to an infrared sensor, the two detectors 11 are installed on the frame 1, and the two detectors 11 respectively correspond to the two material rollers 10 one by one, and are respectively used to detect the remaining amount of the packaging film on the two material rollers 10. Two openings 8 are formed on the mounting frame 5, there are two hot pressing mechanisms 9, and the two hot pressing mechanisms 9 are respectively arranged in the inner cavities of the two openings 8. A clamping member 7 (such as a fixture) is arranged between two adjacent material rollers 10, the clamping member 7 is installed on the frame 1, the end of the packaging film on one material roller 10 passes through its corresponding opening 8 and the adjacent opening 8 in sequence and is clamped by the clamping member 7, while the packaging film on the other material roller 10 is directly guided to the bundling mechanism 4 for use (for example, when the packaging film on the right material roller 10 is pulled to the bundling mechanism 4 for use, the end of the packaging film on the left material roller 10 passes upward through the left opening 8, then passes downward through the right opening 8 and is clamped by the clamping member 7); It should be noted that the packaging films on one material roller 10 of the two upper film components are guided to the bundling mechanism 4 and connected together.
[0019] Please refer to Figure 5 and Figure 6 , the palletizing mechanism 3 includes two side plates 301, two first supporting blocks 303 arranged on the side walls of the two side plates 301 close to each other, two second supporting blocks 304, and a lifting component 305 arranged on the side plates 301; the lifting component 305 includes a cylinder and a push plate installed on the moving end of the cylinder, the push plate is located below the first supporting block 303, the second supporting block 304 is located above the first supporting block 303, and the second supporting block 304 is hinged on the side wall of the side plate 301; the two side plates 301 are horizontally installed on the frame 1; It should be noted that the bottom of the side walls of the two second supporting blocks 304 close to each other is an inclined surface or an arc surface, and when the packaging box moves upward, it will contact the inclined surface or arc surface of the second supporting block 304, which is convenient for the packaging box to move upward over the second supporting block 304.
[0020] Please refer to Figure 7 and Figure 8, the bundling mechanism 4 includes a workbench 401, a heat-sealing mechanism 407, a bracket 404, a pressing member 406 and a driving member; the driving member includes a motor, two rotating shafts and a belt sleeved on the outer walls of the two rotating shafts. The motor is installed on the bracket 404. One rotating shaft is installed on the output shaft of the motor, and the other rotating shaft is installed on the bracket 404. The pressing member 406 is installed on the side wall of the belt. The pressing member is a lower pressing plate. The heat-sealing mechanism 407 is arranged on the top wall of the workbench 401, and the heat-sealing mechanism 407 refers to a heat-sealing machine.
[0021] It should be noted that a rotating roller is installed at the bottom of the lower pressing plate. When the lower pressing plate moves downward, the rotating roller rolls in contact with the packaging film to avoid damaging the packaging film.
[0022] Please refer to Figure 1 , the material pushing mechanism 13 includes a cylinder and a material pushing plate arranged on the moving end of the cylinder. The cylinder is installed on the frame 1 and is located above the palletizing mechanism 3.
[0023] Working principle: The packaging film of the right-side material roller 10 of the two upper film assemblies is pulled to the bundling mechanism 4 and connected. The packaging boxes are sequentially placed on the transmission mechanism 2 and then transmitted to between the two side plates 301 of the palletizing mechanism 3. At this time, the packaging boxes are located above the two first supporting blocks 303; when a predetermined number of packaging boxes (such as four) are accumulated above the two first supporting blocks 303, the lifting assembly 305 works (the cylinder drives the push plate to move upward), and the packaging boxes above the first supporting blocks 303 are pushed upward, so that the packaging boxes push the second supporting block 304 upward and rotate over the second supporting block 304. Then, the lifting assembly 305 resets. The lifted packaging boxes fall onto the top of the second supporting block 304 and are supported. Then, the operation is repeated. The packaging boxes are transmitted by the transmission mechanism 2 to the first supporting blocks 303 and then lifted to the second supporting block 304, so that the packaging boxes start to be palletized on the second supporting block 304; after the packaging boxes are palletized into a predetermined number of layers, the material pushing mechanism 13 works (the cylinder drives the material pushing plate to move), and the palletized packaging boxes are pushed to the top of the workbench 401 of the bundling mechanism 4 and squeeze the packaging film (the packaging film in contact with the packaging boxes forms a C shape); the driving member drives the pressing member 406 to move downward to contact the heat-sealing mechanism 407 on the top of the workbench 401, and pulls the packaging film to wind around the outside of the palletized packaging boxes in a circle. The heat-sealing mechanism 407 cuts the packaging film and connects the two ends of the packaging film wound around the outside of the palletized packaging boxes, completing the bundling of the palletized packaging boxes. At the same time, after connecting the two ends of the packaging film released by the two upper film assemblies again, the driving member drives the pressing member 406 to move upward. Then, the operation is repeated to perform the bundling of the packaging boxes.
[0024] It should be noted that during the bundling process, when the detector 11 detects that the packaging film on the right material roller 10 is almost used up, after receiving this information, the controller controls the hot pressing mechanism 9 on the right to work, heat-seal the two packaging films in the right opening 8 together, and at the same time, the clamping member 7 is also controlled to release the packaging film, so that when the right packaging film is pulled, it will pull the packaging film on the left material roller 10 to start releasing, thus realizing automatic feeding without the need to stop the bundling equipment; when the packaging film on the right material roller 10 is used up, a new packaging film roll is sleeved on the right material roller 10, and the end of the packaging film is passed upward through the right opening 8 and then downward through the left opening 8, and then clamped by the clamping member 7. When the packaging film on the left material roller 10 is almost used up, the two packaging films in the left opening 8 will be heat-sealed together (refer to the above operation process) to realize automatic continuous connection of the packaging film and ensure continuous supply of the packaging film.
[0025] It should also be noted that a cylinder is installed on the frame 1, and a moving plate is installed on the moving end of the cylinder. The cylinder drives the moving plate to move, which is used to push the bundled packaging box away from the workbench 401.
[0026] In this embodiment, as a further optimized solution, please refer to Figure 2 、 Figure 3 and Figure 4 , the upper film assembly further includes a tension roller 6 and a rotating assembly 14. The rotating assembly 14 includes a motor and a swing arm provided on the output shaft of the motor. The tension roller 6 is installed on the swing arm, and the motor is installed on the frame 1; when the right material roller 10 releases the packaging film and becomes the left material roller 10 releasing the packaging film (or vice versa), the motor drives the swing arm to drive the tension roller 6 to move, which is used to tension the packaging film released by the material roller 10.
[0027] In this embodiment, as a further optimized solution, please refer to Figure 5 and Figure 6 , a first adjusting member 302 is provided between the two side plates 301. The first adjusting member 302 includes a screw rod and a handwheel connected to the screw rod. Threaded holes are provided on the side walls of the two side plates 301 close to each other, and the screw rod passes through the two threaded holes; by rotating the handwheel, the distance between the two side plates 301 is adjusted to be suitable for packaging boxes of different widths; limiting baffles 306 are provided above the two side plates 301, which are used to limit the stacked packaging boxes to prevent them from tipping over.
[0028] In this embodiment, as a further optimized solution, please refer to Figure 7 and Figure 8 , a driving device (cylinder) is provided on the bracket 404, and a pressing plate 405 is provided on the moving end of the driving device; the cylinder drives the pressing plate 405 to move downward to press the packaging box to be bundled and press the packaging film on the top of the packaging box, so that the two are in full contact, ensuring the tightness of bundling, and at the same time, the packaging box does not move around during the bundling process.
[0029] In this embodiment, as a further optimized solution, please refer to Figure 7 and Figure 8 , a limiting plate 402 is slidably arranged on the top wall of the workbench 401. The limiting plate 402 faces the bracket 404. A second adjusting member 403 is arranged on the side wall of the workbench 401. The second adjusting member 403 includes a threaded rod and a turntable connected to the threaded rod. The threaded rod is rotatably arranged on the workbench 401. The threaded rod penetrates through the limiting plate 402, and a threaded hole is arranged at the connecting part of the limiting plate 402 and the threaded rod; by rotating the turntable, the threaded rod rotates to drive the limiting plate 402 to approach or move away from the bracket 404. The cooperation between the limiting plate 402 and the bracket 404 is used to limit the bundled packaging box so that it will not move forward and backward, resulting in the collapse of the stacked packaging boxes.
[0030] In this embodiment, as a further optimized solution, please refer to Figure 1 , two groups of guide rollers 12 are arranged on the frame 1 to guide the packaging films released by the two upper film assemblies to the bundling mechanism 4.
