Description
Technical Field
[0001] This utility model relates to the field of box opening device technology, specifically a fully automatic servo robotic box opening machine. Background Technology
[0002] With the development of cardboard box technology, there are more and more cardboard box forms. In order to automate the processing of cardboard boxes, cardboard box opening devices have appeared on the market. A cardboard box opening device is a machine used to assist in completing the processes of opening, forming, folding the bottom and sealing the bottom of cardboard boxes.
[0003] Existing carton opening devices suffer from the following problems during use: 1. Carton loading is usually done manually, requiring workers to place stacked carts onto a trolley-like tool, which then transports the cart and all the carts to the receiving end of a storage device. This results in a complex and poorly designed structure for the existing storage device. Furthermore, the storage device requires a mechanism to limit the cartons' movement, but the existing limiting mechanism cannot be adjusted according to different carton sizes, thus limiting only one size and reducing its practicality. 2. During opening, workers must manually open each carton and then manually apply tape to seal it. However, this process is labor-intensive. 1. Employees will experience fatigue from prolonged box opening work, making manual box opening inefficient and uneconomical. Furthermore, manual opening of larger boxes is cumbersome, further reducing its practicality. 2. The bottom sealing device on the box opening machine typically requires four sets of pusher mechanisms to push four movable cardboard pieces at the bottom of the box to achieve sealing. This makes the structure complex and increases operating costs. After sealing, manual operation is required to apply adhesive tape and then manually cut the tape to output the box. However, using four sets of pusher mechanisms for bottom sealing significantly increases the number of parts in the machine, and manual sealing and tape cutting also lead to low efficiency.

The multiple air outlets 3331 communicate with the multiple air inlets 3341 respectively. An air outlet 3331 is connected to the air intake path, and an air inlet 3341 is used for air intake, thus facilitating the adsorption of the carton onto the surface of the adsorption plate 334. By using an external air extraction device, air is extracted with the aid of the support beam 333 and the adsorption plate 334, allowing the carton dragging on the opening plate 335 to be adsorbed onto the surface of the adsorption plate 334. The structure of the air extraction device is existing technology and will not be described in detail here. The pipes of the air extraction device are connected to the support beam 333, so that the air path of the air extraction device is connected to the air outlet 3331. The end of the adsorption plate 334 away from the attachment plate 332 is fixed with the opening plate 335 and the limiting beam 336. The opening plate 335 is used to push the movable cardboard at the bottom of the carton, changing it from a vertical state to a horizontal state and fitting it against the bottom of the carton.The limiting beam 336 is vertically positioned on one side of the opening plate 335. Therefore, during the movement of the opening plate 335, it can push one side of the movable cardboard at the bottom of the carton, causing the movable cardboard to change from a vertical to a horizontal state and adhere to the bottom surface of the carton. The limiting beam 336 contacts one side of the carton, limiting its movement and ensuring smooth transport to the next processing equipment.
[0049] Please see Figures 11 to 16The bottom sealing device 4 includes a base 41, a feeding assembly 42, a bottom sealing assembly 43, and a sealing assembly 44. The feeding assembly 42 includes two parallel fixed platforms 421 and feeding motors 422 fixed to the lower surfaces of the two fixed platforms 421. Both fixed platforms 421 are fixed to the upper surfaces of the base 41. The output ends of the two feeding motors 422 are connected to conveyor belts 423, which operate synchronously. The two conveyor belts 423 are used to limit the sides of the carton and push it forward. A receiving plate 426 and a conveying plate 427 fixedly connected to the receiving plate 426 are arranged between the two conveyor belts 423. The two conveyor belts 423 are respectively located within the two fixed platforms 421. 2 also includes a receiving plate 424 and a first cylinder 425 fixed on the receiving plate 424. The receiving plate 424 is fixed on the base 41. The output end of the first cylinder 425 is movably connected to a receiving plate 426. The conveying plate 427 is fixed on the receiving plate 424. Therefore, when the first cylinder 425 is running, it can drive the end of the receiving plate 426 away from the conveying plate 427 to bend to a certain extent, so as to better receive the carton. However, the bending of the receiving plate 426 will not affect the structural stability of the receiving plate 426 and the conveying plate 427. The bottom sealing assembly 43 includes two mounting plates 431 and second cylinders 432 respectively fixed on the two mounting plates 431. The two mounting plates 431 are respectively fixed to the lower end face of the two fixed platforms 421. The two second cylinders 432 are fixed on the two mounting plates 431 respectively. The output ends of cylinder 2 are respectively provided with a first connecting plate 433, a second connecting plate 434, and a positioning piece 435. The output ends of the two second cylinders 432 are movably connected to the two first connecting plates 433, and the two first connecting plates 433 are movably connected to the two positioning pieces 435 through the two second connecting plates 434. The upper end surfaces of the two positioning pieces 435 are respectively fixed with bottom sealing plates 436, so that when the two second cylinders 432 are running, they can drive the two positioning pieces 435 to move horizontally, thereby causing the two bottom sealing plates 436 to move horizontally as well, pushing the movable cardboard on both sides of the bottom of the carton closer to each other and fitting against the carton body to seal the bottom of the carton. The two bottom sealing plates 436 can move towards each other to push the movable cardboard on both sides of the bottom of the carton, thereby sealing the bottom of the carton. The sealing assembly 44 includes an extension base 441 and a cutter 442 fixed to the top of the extension base 441. An upper lifting plate 447 is fixed to the end of the extension base 441 away from the cutter 442. A lower extension piece 443 and a tape roll 444 mounted on the lower extension piece 443 are provided at the bottom of the extension base 441. The tape roll 444 is used to hold the tape roll. Two support pieces 445 and sealing rolls 446 are respectively mounted on the top of the extension base 441. The lower extension piece 443 and the support pieces 445 are both fixed to the extension base 441. The upper lifting plate 447 is fixed to the base 41, and the end of the upper lifting plate 447 away from the cutter 442 is bent downwards, thus guiding the carton upwards.The bottom of the carton passes through two sealing rolls 446. During this process, the tape conveyed on the two sealing rolls 446 adheres to the movable cardboard at the bottom of the carton, achieving automatic sealing. In addition, an adjustment assembly 45 is provided on the base 41. The adjustment assembly 45 includes an adjustment motor 451 and a synchronous pulley set connected to the adjustment motor 451. The adjustment motor 451 is fixed on the base 41, and the synchronous pulley set is installed on the outside of the base 41. A housing is provided on the outside of the synchronous pulley set, and the housing is also fixed on the base 41. A lead screw 452 and a guide rod 453 are provided on one side of the synchronous pulley set. The synchronous pulley set is connected to the lead screw 452. The upper part has two parallel lower support seats 454, which are symmetrically arranged at both ends of the lead screw 452. Both lower support seats 454 are mounted on the guide rod 453. Two fixed platforms 421 are respectively fixed to the two lower support seats 454. The lead screw 452 and the guide rod 453 are parallel, and the threads at both ends of the lead screw 452 rotate in opposite directions. Both ends of the guide rod 453 are fixedly connected to the base 41. When the lead screw 452 rotates, the symmetrically arranged lower support seats 454 at both ends will translate in opposite directions, thereby adjusting the distance between the two fixed platforms 421 to accommodate cartons of different sizes.
[0050] Please refer to the following: Figures 1 to 16 In the operation of this utility model, several vertically arranged and pressed together cardboard boxes are first placed on one side of the push plate 227. The position of the push plate 227 can be referred to at this time. Figure 2 The carton is positioned between the push plate 227 and the push motor 221. One end of the carton is restricted by the fixed plate 228, and the other end is restricted by the push plate 227. Therefore, the carton can maintain a stable state. The push motor 221 drives the first main sprocket 222 to rotate, which in turn drives the first chain 224 to drive the first slave sprocket 223. This causes the slider 225 to move horizontally on the first slide rail 226, which in turn pushes the push plate 227 to move all the cartons toward the side where the push motor 221 is located, thus achieving automatic feeding. Finally, all the cartons are sent to the position of the carton opening device 3.
[0051] When the carton approaches the opening device 3, the first motor 321, the second motor 323, and the third motor 326 operate to open the first carton. The three motors drive the opening plate 335 to gradually approach the carton, and the movement of the opening plate 335 pushes the movable cardboard on one side of the bottom of the carton, flattening it from a vertical position. The opening plate 335 and the receiving plate 426 are located on opposite sides of the carton. The movable cardboard on the other side of the bottom of the carton is flattened by the receiving plate 426. In this way, two movable cardboards at the bottom of the carton can be quickly flattened and made to fit together. At the bottom of the carton, multiple air inlets 3341 will then be close to the sides of the carton. At this time, a designated external air extraction device will be used to extract the surrounding air through the multiple air inlets 3341 and multiple air outlets 3331, so that the carton can be attached to the surface of the air inlets 3341. Then, the first motor 321, the second motor 323 and the third motor 326 continue to run, driving the opening plate 335 to continue to push the carton forward, and push the carton to the conveyor plate 427 with the help of the bent receiving plate 426. The limiting beam 336 can limit the carton in the moving state, so that it moves in a straight line.
[0052] After a carton is fed onto the conveyor plate 427, the two feeding motors 422 drive the two conveyor belts 423 to move forward, conveying the carton between the two bottom sealing plates 436. When the carton reaches the bottom sealing plates 436, the two second cylinders 432 are driven to move, bringing the two bottom sealing plates 436 closer together. This pushes the other two opposing movable cardboard pieces at the bottom of the carton to adhere to the bottom of the carton. At this point, all four movable cardboard pieces are adhered to the bottom of the carton. Afterward, the carton moves slightly upward under the action of the lifting plate 447, passes through the two sealing rolls 446, and automatically adheres to the tape conveyed on the two sealing rolls 446, achieving automatic sealing. Finally, the carton is output from above the cutter 442, and the weight of the carton itself presses down on the cutter 442, cutting the tape.
