In the initial state, the fork rod 53 faces the direction of the dust removal bin 4, and the fork rod 53 is located in the gap of the annular belt 31, and the underwear can be transferred to the top of the fork rod 53, so that the underwear can be lifted by the plurality of fork rods 53 along with the driving of the lifting assembly, and sent to the working space 42 along with the driving member fork rod 53 of the translation assembly and the underwear. After dust removal is completed, the fork bar 53 is sent out of the working space 42 by the translation assembly, and the fork bar 51 is rotated by the rotation driving member 56, and the fork bar 53 moves away from the dust removal bin 4, thereby sending the underwear to the direction of the conveyor belt 3 for the next link. Then the lifting assembly moves the fork bar 53 downward, so that the underwear contacts the endless belt 31, and the conveyor belt 3 sends the underwear out of the dust removal link to the folding station 2. In this way, the underwear can be sent to the next link more smoothly.

[0035] Reference Figure 2 and Figure 4 Further, the dust removal assembly includes a plurality of dust removal rollers 61 and dust removal plates 62. The dust removal roller 61 is a cylindrical metal roller, and the dust removal roller 61 is hollow. The dust removal roller 61 is arranged along the length direction of the conveyor belt 3.

The first gear 632 is arranged at both ends of the toothed chain 631 and meshes with the toothed chain 631 from the inside. The first gear 632 drives the toothed chain 631 to rotate in the dust removal bin 4 from both ends. The driving motor 64 is arranged on the dust removal bin 4 to drive the first gear 632 to rotate, and the driving motor 64 is a stepping motor. A plurality of mounting seats 6311 are arranged in sequence on the outside of the toothed chain 631, and the dust removal roller 61 is rotatably connected to the toothed chain 631 through the mounting seats 6311. Two pairs of toothed chains 631 and first gears 632 are arranged at intervals. The two first gears 632 are connected by a connecting rod 6321, and the connecting rod 6321 is connected to the center of the first gear 632. The driving motor 64 is arranged on the outer wall of the dust removal bin 4 away from the folding station 2, and the output shaft of the driving motor 64 passes through the outer wall of the dust removal bin 4 and is connected to the center of the first gear 632. The dust removal roller 61 corresponds to the connecting rod 6321. The centers of both ends of the dust removal roller 61 are provided with rotating shafts 611, which are rotatably connected to the toothed chain 631 through corresponding mounting seats 6311.

[0037] refer to Figure 3 and Figure 5 Further, the second driving assembly includes a plurality of second gears 651 and a driving rail 652. The driving rail 652 is in a runway shape. The driving rail 652 is connected to the dust removal bin 4. A tooth 6521 is provided on the inner side of the driving rail 652. The plurality of second gears 651 are coaxially connected to the corresponding rotating shaft 611. The second gears 651 are meshed with the driving rail 652. Since the second gears 651 are meshed with the tooth 6521 of the driving rail 652, and the second gears 651 are connected to the dust removal roller 61 through the rotating shaft 611, when the dust removal roller 61 is driven to move, the second gears 651 move relative to the driving rail 652, and the second gears 651 are driven to move, thereby driving the dust removal roller 61 to rotate. The dust removal roller 61 can rotate relative to the underwear, thereby absorbing more dust and microorganisms.

[0038] Reference Figure 2 and Figure 4 Further, the dust collection assembly includes two dust removal plates 62, a dust collection pipe 72 and a fan 73. The side wall of the dust collection bin 4 is provided with a dust collection port 43 at a section of the moving path of the dust removal rollers 61. The two dust removal plates 62 are located at the upper and lower sides of the dust collection port 43. The two dust removal plates 62 are provided with a plurality of brushes on the opposite sides thereof. The brushes are made of plastic. The dust collection pipe 72 is connected to the dust collection port 43, and the fan 73 is connected to the dust collection pipe 72.

[0039] Reference Figure 2 and Figure 6Furthermore, the power supply assembly is used to supply static electricity to the dust removal rollers 61.

The power supply rail 81 is arranged on the inner wall of the dust removal bin 4 on the side away from the folding station 2, and the power supply rail 81 is in a runway shape. The electrostatic power source supplies static electricity to the power supply rail 81, and a plurality of connecting wires 82 are connected to one end of the corresponding rotating shaft 611. The connecting wire 82 contacts the power supply rail 81, so that the static electricity is transmitted to the surface of the dust removal roller 61 through the electrostatic power source, the power supply rail 81, and the connecting wire 82. The dust and microorganisms on the underwear are adsorbed by static electricity.

[0040] The implementation principle of an automatic folding machine in the embodiment of the present application is: By providing an electrostatic dust removal structure before the underwear is folded, dust and microorganisms attached to the surface of the underwear can be removed, thereby making the underwear cleaner.

[0041] Specifically, the underwear is sent from the loading position 1 to the dust removal bin 4 via the conveyor belt 3. At this time, the fork rod 53 of the lifting fork 5 is located in the gap between the annular belts 31, and the underwear is sent to the position above the lifting fork 5. The lifting assembly drives the lifting fork 5 to lift the underwear to the level of the working space 42, and the lifting fork 5 is sent to the working space 42 through the translation assembly. The dust removal roller 61 rotates around the underwear, and the power supply assembly 8 supplies static electricity to the dust removal roller 61. The dust removal roller 61 moves and rotates to absorb the dust and microorganisms on the underwear. The dust removal roller 61 moves to the dust removal plate 62, and the brush removes impurities on the surface of the dust roller 61. The impurities are guided to the outside by the fan 73 through the dust suction assembly 7. Thereafter, the translation assembly drives the underwear to withdraw from the working space 42, and the lifting fork 5 is driven by the rotating drive member 56 to rotate in the direction away from the dust removal bin 4. The lifting assembly lowers the lifting fork 5, and the underwear contacts the conveyor belt 3 and is sent to the folding station 2 for folding.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
