Figures 5 to 6This is a schematic diagram of the first flipping component 21 and the second flipping component 22 flipped 180°. The bag body 4 containing the laptop 5 is placed on the bag body support platform 1. By the synchronous flipping of the first flipping component 21 and the second flipping component 22, the bag opening 41 is folded upward and sealed. To maintain the closed state of the bag opening 41 while simultaneously being able to clamp and flip the bag body 4 via the bag body clamping assembly 3, this embodiment adopts the following technical solution: (1) The first folding plate 212 is provided with a plurality of first hollow portions 2121 and a plurality of first strip plates 2122, the first hollow portions 2121 and the first strip plates 2122 being spaced apart; the first telescopic plate 214 is provided with a plurality of second hollow portions 2141 and a plurality of second strip plates 2142, the second hollow portions 2141 and the second strip plates 2142 being spaced apart; the first hollow portions 2121 and the second hollow portions 2141 are staggered, that is, the first strip plates 2122 can be inserted into the second hollow portions 2141, and the second strip plates 2142 can be inserted into the first hollow portions 2121. The first telescopic plate 214 can be extended and retracted by the first telescopic cylinder 213; similarly, the second folding plate 222 is provided with several third hollow portions 2221 and several third strip plates 2222, which are spaced apart. The second telescopic plate 224 is provided with several fourth hollow portions 2241 and several fourth strip plates 2242, which are spaced apart. The third hollow portions 2221 and the fourth hollow portions 2241 are staggered, that is, the third strip plates 2222 can be inserted into the fourth hollow portions 2241, and the fourth strip plates 2242 can be inserted into the third hollow portions 2221. The second telescopic plate 224 can be extended and retracted by the second telescopic cylinder 223. When the rotation angle of the first rotating shaft 211 and the second rotating shaft 221 is 0°, the distance between the first telescopic plate 214 and the second telescopic plate 224 is L1. See [reference needed]. Figure 4 When the rotation angle of the first rotating shaft 211 and the second rotating shaft 221 is 180°, the distance between the first telescopic plate 214 and the second telescopic plate 224 is L2. (See [reference]). Figure 6 L1 < L2, and distance L2 is sufficient to accommodate the width of the first gripper 32; when the bag opening 41 of the bag body 4 is not folded, both the first telescopic plate 214 and the second telescopic plate 224 are extended, increasing the effective folding length of the first folding plate 212 and the second folding plate 222, enabling the entire bag opening 41 to be folded to... Figure 1 (b) shows the state where, when the bag body 41 needs to be gripped by the first gripper 32, both the first telescopic plate 214 and the second telescopic plate 224 are in a retracted state, increasing the gap between the first telescopic plate 214 and the second telescopic plate 224 to accommodate the first gripper 32. See details [link to documentation]. Figure 6The state of the first gripper 32 holding the bag body 4. (2) The gantry bracket 31 includes a horizontal part 311 and a first vertical part 312 and a second vertical part 313 disposed at both ends of the horizontal part 311; a third belt 314 is disposed below the horizontal part 311, and a first connecting plate 315 and a second connecting plate 316 are disposed on the third belt 314; the third belt 314 drives the first connecting plate 315 and the second connecting plate 316 to move closer or further away from each other; the first connecting plate 315 drives the first vertical part 312 to move, and the second connecting plate 316 drives the second vertical part 313 to move. When the first telescopic plate 214 and the second telescopic plate 224 are both in the retracted state and the gap between them is L2, the third belt 314 drives the first vertical part 312 and the second vertical part 313 to move closer to each other, so that the first gripper 32 and the second gripper 33 are respectively aligned with the two ends of the bag body 4 and clamped. The first gripper 32 is clamped at the gap between the first telescopic plate 214 and the second telescopic plate 224. See details. Figure 6 A second motor 317 and a first rotating part 318 driven by the second motor 317 are provided at the bottom end of the first vertical part 312. The second gripper 33 is installed on the first rotating part 318. A second rotating part 319 is provided at the bottom end of the second vertical part 313. The first gripper 32 is installed on the second rotating part 319. When the first gripper 32 and the second gripper 33 clamp the bag body 4, the first rotating shaft 211 and the second rotating shaft 221 rotate 180° to release the bag body 4. After the first gripper 32 and the second gripper 33 transfer the bag body 4, the second motor 317 is started to rotate the bag body 180° to achieve... Figure 1 The state shown in (c) is ready for the subsequent loading of bag 4 into the packaging box. It should be noted that a straight module (not shown in the figure) is provided at the top of the horizontal part 311, and the gantry bracket 31 is transferred to the next process through the straight module.
[0056] See Figures 2 to 4 The first rotating shaft 211 is mounted on the first bracket 23, and a through shaft 24 is also mounted on the first bracket 23. The driven end 241 of the first rotating shaft 211 and the through shaft is driven by the first belt 25.

The through shaft 24 is driven by the first motor 28. The first motor 28 drives the through shaft 24 to rotate, and the driven end 241 of the through shaft and the first belt 25 drive the first rotating shaft 211 to rotate. Simultaneously, the driven end 242 of the through shaft and the second belt 27 drive the second rotating shaft 221 to rotate, ensuring the synchronicity of the rotation of the first flipping component 21 and the second flipping component 22.
[0057] See Figures 2 to 4A translation module is arranged below the bag body supporting platform 1, and the translation module drives the bag body supporting platform 1 to move toward or away from the bag mouth folding assembly 2. The position of the bag body supporting platform 1 is finely adjusted by the translation module, so that the folding positions of the first folding plate 212 and the second folding plate 222 are more accurate.
[0058] Through this embodiment, the bag mouth 41 is folded through the synchronous flipping of the first flipping assembly 21 and the second flipping assembly 22; through the adjustment of the gap between the first telescopic plate and the second telescopic plate, the first clamping jaw 32 can clamp the folded bag mouth 41, avoiding the rebound of the bag mouth 41; then through the flipping action of the first clamping jaw 32, the entire bag body 4 is flipped by 180°, and the folded bag mouth 41 is pressed by the weight of the bag body 4 and the notebook computer in the bag body. Therefore, even without using an adhesive method to fix the folded bag mouth 41, the folded bag mouth 41 can be prevented from rebounding, fully automatic and efficient bag mouth folding is realized, and a foundation is provided for subsequent efficient boxing of notebook computers.

[0063] Step S2: the first telescopic plate 213 and the second telescopic plate 214 extend out simultaneously, the first rotating shaft 211 and the second rotating shaft 221 rotate synchronously by 180°, and the first folding plate 212, the first telescopic plate 214, the second telescopic plate 224 and the second folding plate 222 flip and compress the bag mouth 41 simultaneously, for details, see Figure 1 (b);
[0064] Step S3: the first telescopic plate 214 and the second telescopic plate 224 retract simultaneously, so that a gap 6 is formed between the first telescopic plate 214 and the second telescopic plate 224, and the length of the gap 6 is expanded to L2;
[0065] Step S4: The first gripper 32 and the second gripper 33 approach each other. The first gripper 32 clamps one side of the bag body 4 from the gap 6, and the second gripper 33 clamps the other side of the bag body 4. Before the first gripper 32 clamps the folded bag opening 41 of the bag body 4, the first flipping component 21 and the second flipping component 22 maintain their folded state.
[0066] Step S5: The first rotating shaft 211 and the second rotating shaft 212 rotate 180° to release the bag body 4. At this time, the folded bag opening 41 is clamped by the first gripper 32.
[0067] Step S6: The first gripper 32 and the second gripper 33 remove the bag body 4, rotate 180° and place the bag body 4 at the next workstation. The folded bag opening 41 of the bag body 4 is pressed down by the bag body 4 and the laptop computer inside the bag. See details. Figure 1 (c)
