Among them, the inner ear folding mechanism 32 includes: an eleventh linear driver 321, a connecting seat 322, and an eighth guiding baffle 323.

The ninth guiding baffle 332 is driven by the twelfth linear driver 331 to reciprocate in a direction parallel to the moving direction of the eighth guiding baffle 323. Then, when the first rotating driver 221 drives the first rotating baffle 222 to rotate upward by 90° from the horizontal state shown in Figure 1 to the vertical state shown in Figure 4 , both the inner ear folding mechanism 32 and the pressing and inserting mechanism 33 rotate upward by 90° along with the first rotating baffle 222, that is, both the eighth guiding baffle 323 and the ninth guiding baffle 332 rotate synchronously with the first rotating baffle 222 to the vertical state shown in Figures 4 to 7 . The eighth guiding baffle 323 is located above the front side of the bearing plate 111, and the ninth guiding baffle 332 is located above the eighth guiding baffle 323. When the fifth rotating baffle 312 pushes the box lid 202 forward to fold it to the inclined state shown in the H state diagram in Figure 9 (at this time, the inner ear 215 is directly below the eighth guiding baffle 323), the box lid 202 is adsorbed and fixed by the third suction cup 313 to prevent the box lid 202 from falling downward. The eleventh linear driver 321 drives the eighth guiding baffle 323 to move vertically downward, and the inner ear 215 is pushed downward by the eighth guiding baffle 323 to be perpendicular to the box lid 202. The fifth rotating baffle 312 pushes the box lid 202 to continue folding forward. When the box lid 202 is folded to directly below the ninth guiding baffle 332, the twelfth linear driver 331 drives the ninth guiding baffle 332 to move vertically downward, and the connection between the box lid 202 and the inner ear 215 is pushed by the ninth guiding baffle 332 to push the inner ear 215 into the corresponding inner jack 216 until the packaging box 200 is closed asFigure 9 The three-dimensional closed cover state shown in the middle J state diagram.

[0051] Combined with the accompanying drawings, the working principle of the folding box closing device 100 of the present application will be described in detail:

[0052] When the right side of the first guiding baffle 132 moves to be flush with the right side of the left limiting guiding plate 12a, and the left side of the first guiding baffle 132 moves to be flush with the left side of the right limiting guiding plate 12b, the Figure 8 packaging box 200 in the plane unfolded state shown is transported by an external handling manipulator to the area between the left limiting guiding plate 12a and the right limiting guiding plate 12b with the box bottom 201 aligned and pushed downward to fall onto the bearing plate 111. During the downward movement of the packaging box 200 in the plane unfolded state, the first guiding baffle 132 pushes the lower left cushion surface 207 upward to be folded to a vertical state, and the second guiding baffle 142 pushes the lower right cushion surface 208 upward to be folded to a vertical state. When the box bottom 201 falls onto the bearing plate 111 and is adsorbed by the first suction cup 112, the first fixed baffle 133 pushes the lower left cushion surface 207 to maintain the vertical state, and the second fixed baffle 143 pushes the lower right cushion surface 208 to maintain the vertical state, so that the lower left cushion surface 207 and the lower right cushion surface 208 are folded to the state as shown in Figure 9 the A state diagram in.

[0053] Then, the left box surface folding mechanism 15 and the right box surface folding mechanism 16 cooperate to fold. That is, when the third linear driver 151 drives the third guiding baffle 152 to move vertically upward and extend out of the substrate 10, the third guiding baffle 152 can push the left box surface 205 upward to be folded; when the fourth linear driver 161 drives the fourth guiding baffle 162 to move vertically upward and extend out of the substrate 10, the fourth guiding baffle 162 can push the right box surface 206 upward to be folded, so that the left box surface 205 and the right box surface 206 are folded to the state as shown in Figure 9 the B state diagram in.

[0054] Among them, during the downward movement of the packaging box 200 in the plane unfolded state, the left front side ear folding mechanism 17 and the right front side ear folding mechanism 18 cooperate to fold at the same time. That is, the fifth linear driver 171 drives the fifth guiding baffle 172 to move to be flush with the right side of the left limiting guiding plate 12a, and the sixth linear driver 181 drives the sixth guiding baffle 182 to move to be flush with the left side of the right limiting guiding plate 12b, so that the fifth guiding baffle 172 pushes the left front side ear 212 upward to be folded to a vertical state, and the sixth guiding baffle 182 pushes the right front side ear 213 upward to be folded to a vertical state, so that the left front side ear 212 and the right front side ear 213 are folded to the state as shown in Figure 9 the C state diagram in.

[0055] Then, the rear box surface folding mechanism 19 cooperates for folding. When the box bottom 201 is carried on the carrier plate 111 and adsorbed by the first suction cup 112, the seventh linear driver 191 drives the seventh guiding baffle 192 to move vertically upward to push the rear box surface 204 upward to be folded to a vertical state. At the same time, it drives the lower left cushion surface 207 to rotate and stack on the left end of the box bottom 201, and drives the lower right cushion surface 208 to rotate and stack on the right end of the box bottom 201, so that the rear box surface 204 is folded to be as shown in Figure 9 the D state diagram in. At this time, the first guiding baffle 132 moves to the right and extends out of the right side surface of the left limit guiding plate 12a, and the second guiding baffle 142 moves to the left and extends out of the left side surface of the right limit guiding plate 12b to block and limit the box cover 202 in a vertical state to prevent the box cover 202 from being accidentally bent.

[0056] Next, the front box surface folding mechanism 22 cooperates for folding. The first rotary driver 221 drives the first rotating baffle 222 to rotate upward by 90° from the Figure 1 horizontal state shown to the Figure 4 vertical state shown to push the front box surface 203 upward to be folded to a vertical state. At the same time, it drives the left front side ear 212 to rotate and closely adhere to the right side of the left box surface 205, and drives the right front side ear 213 to rotate and closely adhere to the left side of the right box surface 206, and drives the upper flat tongue 214 to rotate to a vertical state, so that the front box surface 203 is folded to be as shown in Figure 9 the E state diagram in, and adsorbs and fixes the front box surface 203 to maintain a vertical state through the second suction cup 223.

[0057] Then, the left inner tongue folding mechanism 23 and the right inner tongue folding mechanism 24 cooperate for folding, that is, the second rotary driver 231 drives the first rotating mounting seat 232 to drive the second rotating baffle 234 to flip to the right from the Figure 1 position on the left outer side of the carrier plate 111. The second rotating baffle 234 pushes the left inner tongue 209 to fold downward and to the right to the right side of the left front side ear 212. Then, the eighth linear driver 233 drives the first pressing plate 235 to press against the left inner tongue 209 and tightly adhere to the right side of the left front side ear 212 to further strengthen the folding of the left inner tongue 209 in place, as shown in Figure 9 the F state diagram in, so that the left front side ear 212 is clamped between the left box surface 205 and the left inner tongue 209. And the third rotary driver 241 drives the second rotating mounting seat 242 to drive the third rotating baffle 244 to flip to the left from the Figure 1 position on the right outer side of the carrier plate 111. The third rotating baffle 244 pushes the right inner tongue 211 to fold downward and to the left to the left side of the right front side ear 213. Then, the ninth linear driver 243 drives the second pressing plate 245 to press against the right inner tongue 211 and tightly adhere to the left side of the right front side ear 213 to further strengthen the folding of the right inner tongue 211 in place, as shown inFigure 9 As shown in the F state diagram, the right front ear 213 is clamped between the right box surface 206 and the right inner tongue 211.

[0058] Next, it is further folded by the cooperation of the upper flat tongue folding mechanism 25. When the first rotation driver 221 drives the first rotating baffle 222 to rotate upward by 90° from Figure 1 the horizontal state shown to Figure 4 the vertical state shown, the upper flat tongue folding mechanism 25 also rotates upward by 90° along with the first rotating baffle 222. That is, the fourth rotating baffle 253 rotates synchronously with the first rotating baffle 222 to the vertical state, and the upper flat tongue 214 also rotates with the front box surface 203 to the Figure 9 vertical state shown in the E state diagram and the F state diagram in Figures 4 to 7 Then, the tenth linear driver 251 drives the rotating seat 252 to drive the fourth rotating baffle 253 to rotate from the vertical state to Figure 9 the horizontal state shown, so as to push the upper flat tongue 214 to rotate to the

[0059] Next, it is further folded by the cooperation of the lid folding mechanism 31. The fourth rotation driver 311 drives the fifth rotating baffle 312 to rotate forward, and the fifth rotating baffle 312 pushes the lid 202 to fold forward to Figure 9 the inclined state shown in the H state diagram in

[0060] Then, it is further folded by the cooperation of the inner ear folding mechanism 32 and the pressing and inserting mechanism 33. When the first rotation driver 221 drives the first rotating baffle 222 to rotate upward by 90° from Figure 1 the horizontal state shown to Figure 4 the vertical state shown, both the inner ear folding mechanism 32 and the pressing and inserting mechanism 33 rotate upward by 90° along with the first rotating baffle 222. That is, both the eighth guiding baffle 323 and the ninth guiding baffle 332 rotate synchronously with the first rotating baffle 222 to Figures 4 to 7 the vertical state shown. The eighth guiding baffle 323 is located above the front side of the bearing plate 111, and the ninth guiding baffle 332 is located above the eighth guiding baffle 323. When the fifth rotating baffle 312 pushes the lid 202 to fold forward to Figure 9When in the inclined state shown in the middle H state diagram (at this time, the insertion lug 215 is directly below the eighth guiding baffle 323), the third suction cup 313 adsorbs and fixes the box cover 202 to prevent the box cover 202 from falling downward. The eleventh linear driver 321 drives the eighth guiding baffle 323 to move vertically downward, and the eighth guiding baffle 323 pushes the insertion lug 215 to fold downward until it is perpendicular to the box cover 202. The fifth rotating baffle 312 pushes the box cover 202 to continue folding forward. When the box cover 202 is directly below the ninth guiding baffle 332, the twelfth linear driver 331 drives the ninth guiding baffle 332 to move vertically downward, and the ninth guiding baffle 332 pushes at the connection between the box cover 202 and the insertion lug 215 to push the insertion lug 215 into the corresponding insertion hole 216 until the packaging box 200 is closed to the Figure 9 three-dimensional closed cover state shown in the middle J state diagram, so that the folding box operation and the closing cover operation are completed at the same station.

[0061] Since the folding device and the box cover 202 mechanism of the folding and closing device 100 of the present application are both arranged on the substrate 10, the folding device folds the packaging box 200 from the flat unfolded state into the three-dimensional open cover state; the closing device closes the packaging box 200 from the three-dimensional open cover state to the three-dimensional closed cover state. Then, only at the same station on the substrate 10, the folding device folds the packaging box 200 from the flat unfolded state into the three-dimensional open cover state, and then the closing device closes the packaging box 200 from the three-dimensional open cover state to the three-dimensional closed cover state, so that the folding box operation and the closing cover operation can be completed at the same station without repeatedly transferring the packaging box 200 to separate multiple stations to separately complete the folding box operation and the closing cover operation of folding and forming. The structure is simpler, the manufacturing cost is greatly reduced, the floor area is smaller, and the operation cycle speed is faster, and the efficiency is greatly improved, which can better match the high-speed production line.
