Therefore, when the first driver is working, the first driver drives the first worm to rotate, and the first worm drives the first screw 623a to rotate, so that the rotation of the vertical plane is converted into the rotation of the horizontal plane, thereby reducing the installation space of the first driver; The rotation of a screw rod 623a drives the first nut seat 624a to move up and down, thereby driving the first cross bar 621a to move up and down, so that the first rolling mechanism 651 can be adapted to cartons of different heights. Of course, in other embodiments, the first screw 623a can be directly connected to the first driver, without the first worm, so it is not limited thereto.

Please refer to FIG. 9 , the second bracket 62b further includes second vertical bars 622b erected on both sides of the transfer table mechanism 61 , and the second horizontal bar 621b can slide vertically relative to the second vertical bars 622b. The structural manner in which the second horizontal bar 621b slides on the second vertical bar 622b is the same as the structural manner in which the first horizontal bar 621a slides on the first vertical bar 622a, so details will not be repeated here.

Please refer to FIG. 6 and FIG. 7 , the transmission platform mechanism 61 includes a support frame 611 , a roller 612 and a side power structure 613 . There are several rollers 612 arranged at intervals from each other. The rollers 612 are all arranged along the width direction of the support frame 611. There are two side power structures 613 and they are arranged oppositely. The side power structures 613 are installed on the support frame 611 and located on the above the shaft 612 . It can be understood that the distance between the power structures 613 on both sides is the width of the passing carton, so that the side power structure 613 drives the carton 200 forward along the conveying direction. It is worth noting that, in this embodiment, the side power structure 613 provides forward power for the carton 200, and the roller 612 is driven to reduce friction. Of course, in other embodiments, the roller 612 can be actively rolled, and the rotation speed of the roller 612 is consistent with the speed of the side power structure 613 , so it is not limited thereto. The structure of the side power structure 613 is consistent with the structure of the belt guide mechanism 48, so it will not be repeated here.

Please refer to Fig. 6 and Fig. 7, capping mechanism 63 comprises forming frame 631, swing arm 632 and guide bar 633, and the first end of forming frame 631 is installed on the side of second cross bar 621b, and the swing arm 632 and forming frame 631 The second end is pivotally connected, and the guide rods 633 are installed on the second cross bar 621b and are respectively arranged on both sides of the forming frame 631. The forming frame 631 extends downward with a horizontal baffle plate 6311. The conveying direction is arranged from high to low, and the two guide rods 633 also gradually move closer together from outside to inside along the conveying direction of the conveying table mechanism 61 . When the carton 200 passes through the capping mechanism 63, the front flap of the carton 200 is flattened by the horizontal baffle 6311, the swing arm 632 pivots to hit the rear flap, and the two guide rods 633 move the left and right flaps from front to back. Simultaneously press down, and after four flaps are folded, stick the adhesive tape through the glue-applying mechanism 64. Preferably, the front end of the horizontal baffle 6311 is also provided with a circular arc transition structure 6311a, which reduces damage to the front flap and makes the top sealing reliable. Capping mechanism 63 also comprises the driving cylinder 634 that is installed in forming frame 631, and the output end of driving cylinder 634 is connected with swing arm 632, the pivot point of swing arm 632 and forming frame 631, the installation point of driving cylinder 634 and forming frame 631 and The connection points of the swing arm 632 and the driving cylinder 634 jointly form three points of a triangle. Therefore, with the help of the driving cylinder 634, when the output end of the driving cylinder 634 is extended, the swing arm 632 is driven to pivot upwards around the pivot joint, so that the swing arm 632 is reset. When the output end of the driving cylinder 634 is shortened, the swing arm 632 is driven to pivot around the pivot point. The joint pivots downward so that the swing arm 632 strikes the flap at the rear.

It is worth noting that the structural principle of the gluing mechanism 64 is well known to those skilled in the art, so it will not be repeated here. It can be understood that, in this embodiment, a conveying device is connected to the output end of the sealing device 6 so as to transfer the packed cartons 200 , but it is not limited thereto.

In conjunction with the accompanying drawings, the working principle of the automatic carton packaging line 100 of the present invention is described: the carton 200 is initially flat and stored in the rack 42 vertically, and the sliding mechanism 44 drives the suction cup 43 to move toward the rack 42, and the suction cup 43 sucks For the carton 200, the sliding mechanism 44 drives the suction cup 43 to move away from the rack 42. During this process, the forming guide rod 45 pushes the side of the carton 200, so that the carton 200 is opened and formed. The folding bottom cover mechanism 46 at the bottom of the rack closes the four folding covers at the bottom, and the sliding mechanism 47 drives the forming guide rod 45 to move along the transmission direction of the transmission device 3, and pushes the carton 200 onto the belt guide mechanism 48. While the belt guiding mechanism 48, under the effect of the pressing plate 49 and the bottom glueing mechanism 50, the bottom glueing of the carton is completed. After the carton 200 comes out from the unpacking device 4, it reaches the second station through the transmission device 3. The weighing block 51 of the weighing detection device 5 lifts the carton 200 and weighs it. If it is qualified, the transmission device 3 continues to drive the carton 200 to the next station. Sealing device 6; if unqualified, when the transmission device 3 drives the carton to pass the actuator, the carton is pushed to the execution conveying device 8 by the push plate 72. When the carton 200 reaches the sealing device 6 , it is located between the power structures 613 on both sides. The sealing device 6 seals and glues the flap on the top of the carton 200 .

Compared with the prior art, the carton packaging automatic line 100 of the present invention cooperates with the transmission device 3, the unpacking device 4, the detection and weighing device 5 and the sealing device 6, and the unpacking device 4 is located at the first station, and the flat After the carton 200 passes through the unpacking device 4, it is formed and opened and the flap at the bottom of the carton 200 is sealed and pasted with glue. After the 200 is transported to the transmission device 3, before reaching the second station, the product can be packed into the carton by a robot, or the product can be manually packed into the carton, and the carton 200 is driven by the transmission device 3 to stay at the second station. The weighing detection device 5 of the station has a weighing block 51, and the transmission device 3 has several rollers 31 spaced apart. Rising or falling, when weighing is required, the weighing block 51 rises to jack up the carton 200, and detects the weight of the product in the carton 200 to detect whether an object is missing in the carton 200; after the detection is completed, the weighing block 51 descends, When qualified products pass through the third station, the sealing device 6 at the third station seals and glues the top flap of the carton. Therefore, the carton packaging automatic line 100 of the present invention has the advantages of high degree of automation and the ability to detect whether product items are missing, thereby reducing the number of carton scrapping and subsequent rework caused by missing products, thereby reducing the cost of mistakes and increasing the accuracy rate .

The above disclosures are only preferred examples of the present invention, and should not be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention all fall within the scope of the present invention.
