The current way of packing clothes is usually that workers place the clothes on a folding machine, and then use the folding machine to fold the clothes. Then, the workers take out the folded clothes and transfer them to the packing machine, and the packing machine is used to pack the folded clothes into bags. At present, after the clothes are bagged, the existing packing machine usually needs to seal the opening of the packaging bag through a sealing mechanism. The sealing mechanism generally uses a heat sealing method to directly heat seal the opening of the packaging bag.

[0022] The rotation drive module 21 can adopt the structure of the existing motor and the transmission wheel module to drive the first rotating shaft 22 or the second rotating shaft 23 to rotate. In this embodiment, the rotation drive module 21 is connected to the first rotating shaft 22, and the first rotating shaft 22 is driven to rotate by the rotation drive module 21, and the second rotating shaft 23 is driven to rotate by the synchronous transmission member 24, so that the packaging bag containing the clothing is transported by the synchronous transmission member 24.

[0023] See also Figures 1 to 3In this embodiment, the conveying assembly 2 also includes a first elastic member 27 and a second elastic member 28. The first elastic member 27 abuts between the first roller 25 and the frame 1 along the moving direction of the first roller 25, and the second elastic member 28 abuts between the second roller 26 and the frame 1 along the moving direction of the second roller 26. When the conveying assembly 2 conveys the bag opening of the packaging bag to above the first roller 25 and the second roller 26, the first bag opening module 3 and the second bag opening module 4 are lowered to press down the bag opening of the packaging bag; then the first bag opening module 3 and the second bag opening module 4 are moved in directions away from each other to drive the first roller 25 and the second roller 26 to move in directions away from each other and flatten the bag opening of the packaging bag.

[0025] See also Figure 1 and Figure 2In this embodiment, the first bag opening module 3 includes a first bag opening lifting driving mechanism 31 and a first pressing block 32. The first bag opening lifting driving mechanism 31 can be laterally arranged on the crossbar 11. The output end of the first bag opening lifting driving mechanism 31 is connected to the first pressing block 32. The first pressing block 32 is located above the first roller 25. The first bag opening lifting driving mechanism 31 is used to drive the first pressing block 32 to descend so that the first pressing block 32 presses down the bag opening of the packaging bag located on the first roller 25. Specifically, the bottom surface of the first pressing block 32 is a concave structure. Therefore, when the first pressing block 32 presses down the bag opening of the packaging bag, the surface contact can be converted into two point contacts, which is more conducive to flattening the bag opening of the packaging bag. Furthermore, a first bag-pulling opening installation member 33 is provided between the first bag-pulling opening lifting driving mechanism 31 and the first pressing block 32, and the first bag-pulling opening installation member 33 is provided with a first clamping groove 331.

The output end of the second bag opening lifting drive mechanism 41 is connected to the second pressing block 42. The second pressing block 42 is located above the second roller 26. The second bag opening lifting drive mechanism 41 is used to drive the second pressing block 42 to descend so that the second pressing block 42 presses down the bag opening of the packaging bag located on the second roller 26. Specifically, the bottom surface of the second pressing block 42 is a concave structure. Therefore, when the second pressing block 42 presses down the bag opening of the packaging bag, the surface contact can be converted into two point contacts, which is more conducive to flattening the bag opening of the packaging bag. Furthermore, a second bag-pulling opening installation member 43 is provided between the second bag-pulling opening lifting driving mechanism 41 and the second pressing block 42, and the second bag-pulling opening installation member 43 is provided with a second clamping groove 431.

[0030] The bag mouth of the packaging bag is conveyed to the top of the first roller 25 and the second roller 26 by the conveying assembly 2, and the first bag mouth lifting and lowering driving mechanism 31 of the first bag mouth pulling module 3 drives a bag mouth pulling installation member connected to the first pressing block 32 to descend, so that the first pressing block 32 presses down the bag mouth of the packaging bag located on the first roller 25, and the second bag mouth pulling and lowering driving mechanism 41 of the second bag mouth pulling module 4 drives a bag mouth pulling installation member connected to the second pressing block 42 to descend, so that the second pressing block 42 presses down the bag mouth of the packaging bag located on the second roller 26; then the transverse driving assembly 5 drives the first bag mouth pulling module 3 and the second bag mouth pulling module 4 to move away from each other, so that the first pressing block 3 2 drives the first roller 25 and the bag opening of the packaging bag thereon to move, and the second pressing block 42 drives the second roller 26 and the bag opening of the packaging bag thereon to move, so as to flatten the bag opening of the packaging bag. In this process, the first roller 25 compresses the first elastic member 27, and the second roller 26 compresses the second elastic member 28. When the first bag opening pulling module 3 and the second bag opening pulling module 4 move in the opposite direction and rise to reset, the first bag opening pulling module 3 and the second bag opening pulling module 4 are separated from the first roller 25 and the second roller 26. The first roller 25 can move and reset under the elastic force of the first elastic member 27, and the second roller 26 can move and reset under the elastic force of the second elastic member 28.

[0031] In summary, the clothing bagging bag opening pulling mechanism 100 of the utility model is provided with a movable first roller 25 and a second roller 26 on the first rotating shaft 22 of the conveying component 2, and by setting the first bag opening pulling module 3 and the second bag opening pulling module 4, when the conveying component 2 conveys the bag opening of the packaging bag to the top of the first roller 25 and the second roller 26, the first bag opening pulling module 3 and the second bag opening pulling module 4 are lowered to press down the bag opening of the packaging bag, and then the first bag opening pulling module 3 and the second bag opening pulling module 4 are moved in directions away from each other to drive the first roller 25 and the second roller 26 to move in directions away from each other and pull the bag opening of the packaging bag flat, so as to facilitate the subsequent sealing mechanism to seal the flat bag opening, avoid uneven sealing position of the packaging bag, and improve the sealing quality and aesthetics of the sealing.
