The first swing arm 234 is hinged to the first hinge shaft 233, and the first swing cylinder 235 drives the first side folding plate 236 and the first pre-folding plate 237 through the first swing arm 234. The first pre-folding plate 237 swings left and right; the second side folding assembly 24 has a second swing arm 241, a second swing cylinder 242, a second side folding plate 243 arranged at the end of the second swing arm 241, and a second pre-folding plate 244 arranged on the side of the second swing arm 241, the second swing arm 241 is hinged to the second hinge shaft 233, and the second swing cylinder 242 drives the second side folding plate 243 and the second pre-folding plate 244 to swing left and right through the second swing arm 241; the box bottom sealing assembly 3 includes a centering assembly 31, a bottom sealing mechanism 32 and a pressing assembly 33.

[0041] Specifically, this embodiment is carried out according to the following steps: the first step is to refer to Figure 2 and Figure 3 The first suction cup 12 and the second suction cup 13 in a flattened state driven by the manipulator 11 suck the folded carton, and the first telescopic cylinder 14 drives the second suction cup 13 to swing 90° with the first suction cup 12 as a fulcrum, so that the carton becomes a cylinder;

[0042] In the second step, the first cylinder 211 retracts and pushes the first straight rack 212, the first straight rack 212 meshes with the first transmission gear 214 and makes the end of the first folding plate 215 face the ground; the second cylinder 221 retracts and pushes the second straight rack 222, the second straight rack 222 meshes with the second transmission gear 224 and makes the end of the second folding plate 225 face the ground; the first swing cylinder 235 drives the first side folding plate 236 to move outward to a predetermined position through the first swing arm 234, and synchronously, the first pre-folding plate 237 follows and is in a tilted state; the second swing cylinder 242 drives the second side folding plate 243 to move outward to a predetermined position through the second swing arm 241, and the second pre-folding plate 244 follows and is in a tilted state; the first pre-folding plate 237 in the tilted state and the second pre-folding plate 244 in the tilted state form an "eight" shape, see details Figure 5 ;

[0043] In the third step, the manipulator 11 drives the bottom surface of the preformed box (tubed box) toward the box folding assembly 2, the front short side 41 and the rear short side 42 of the box 4 correspond to the front folding assembly 21 and the rear folding assembly 22 respectively, the first pre-folding plate 237 abuts against the first side long side 43 and guides the first side long side 43 to expand outward, the second pre-folding plate 244 abuts against the second side long side 44 and guides the second side long side 44 to expand outward, so that the second side long side 44 and the second side long side 44 form an "eight" shape, see Figure 5 The dotted line shown; or, the first pre-folding plate 237 is driven by the third cylinder 2371, and the third cylinder 2371 is installed on the side of the first swing arm 234, and the second pre-folding plate 244 is driven by the fourth cylinder 2441, and the fourth cylinder 2441 is installed on the side of the second swing arm 241. Before the box body 4 arrives, the third cylinder 2371 and the fourth cylinder 2441 are in a contracted state. After the box body 4 arrives, the third cylinder 2371 and the fourth cylinder 2441 are in an extended state and make the second side long side 44 and the second side long side 44 expand outward respectively to form an "eight" shape; the first side long side 43 and the second side long side 44 in the "eight" shape state avoid the front short side 41 and / or the rear short side 42 during the inward folding process, thereby preventing the first side long side 43 or the second side long side 44 from interfering with the front short side 41 and / or the rear short side 42;

[0044] Step 4: The first cylinder 211 drives the first spur rack 212 to extend, and the first spur rack 212 drives the first folding plate to swing 90° from bottom to top through the first transmission gear 214 and the first transmission shaft 213, and the first folding plate 215 folds the front short edge and remains stationary; the second cylinder 221 and the first cylinder 211 act synchronously, and the second cylinder 221 drives the second spur rack 222 to extend, and the second spur rack 222 drives the second folding plate 225 to swing 90° from bottom to top through the second transmission gear 224 and the second transmission shaft 223, and the second folding plate 225 folds the rear short edge and remains stationary;

[0045] In the fifth step, the first swing cylinder 235 drives the first side folding plate 236 to move inward through the first swing arm 234, and the first pre-folding plate 237 moves inward with it, and the first side folding plate 236 folds the first side long side 43; the second swing cylinder 242 drives the second side folding plate 243 to move inward through the second swing arm 241, and the second pre-folding plate 244 moves inward with it, and the second side folding plate 243 folds the second side long side 44; the first folding plate 215 is clamped in the gap between the first side long side 43 and the second side long side 44 after folding; the first pre-folding plate 237 and the second pre-folding plate 244 are staggered, and no interference occurs when the first pre-folding plate 237 and the second pre-folding plate 244 move inward at the same time;

[0046] In the sixth step, the manipulator 11 delivers the folded box body 4 to the centering component 31, and the manipulator 11 extracts the box body 4 from the first folding plate 215 and the second folding plate 225; since the first folding plate 215 is clamped in the gap between the first side long side 43 and the second side long side 44 after folding, the box body 4 is easily extracted from the first folding plate 215; when extracting the box body 4, the box body 5 is away from the second folding plate 225, and the box body 4 is also easily extracted from the second folding plate 225; in the process of extracting the box body 4, the long side and the short side of the box body 4 must be kept in the inward folded state, which requires that the displacement of the manipulator 11 in the height direction cannot be too large, until the long side and the short side of the box body 4 contact the bottom surface of the centering component 31, the manipulator 11 can release the box body 4;

[0047] In the seventh step, when the bottom sealing mechanism 32 seals the bottom of the box body 4, the pressing assembly 33 presses down the box body 4. The bottom sealing mechanism 32 can adopt an existing bottom sealing mechanism, which will not be described in detail here.

[0048] Follow the steps 1 to 7 above to complete the box body forming, folding the short sides, folding the long sides and sealing the bottom of the box.

[0049] It should be noted that see Figure 1The centering component 31 includes a supporting roller 311 and a first belt 312 and a second belt 313 arranged on both sides of the supporting roller 311. The first belt 312 and the second belt 313 are close to each other to center the box body 4. After the centering, the box body is sent into the bottom sealing mechanism 32 under the clamping of the first belt 312 and the second belt 313.

[0050] Through this embodiment, the folded box is formed, the short sides are folded, the long sides are folded and the bottom is sealed, with a high degree of automation. In particular, the box folding assembly can synchronously fold the front and rear short sides, and can also synchronously fold the left and right long sides; before folding the front and rear short sides, the left and right long sides are respectively expanded outward by the first pre-folding plate and the second pre-folding plate to avoid the long sides interfering with the folding of the short sides; when folding the front and rear short sides, the narrow side of the first folding plate 215 faces the ground and is sandwiched in the gap between the two folded long sides, and the wide side of the second folding plate 225 faces the ground, so as to facilitate the subsequent transfer of the folded box 4 to the box bottom sealing assembly 3 by the robot 11, thereby realizing the continuous operation of multiple processes and greatly improving the efficiency.
