[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When filling and sewing underwear, the personnel first place the underwear between the upper surfaces of the two track plates and ensure that the filling position of the sponge lining is directly below the sewing machine. Then the personnel manually presses the dial to overcome the elastic force of the second spring and appropriately retract into the interior of the hollow box. At this time, the limit ring will move out of the interior of the limit groove to release the vertical limit of the dial. Then the personnel manually overcome the elastic force of the first spring and move the dial, the protruding rod and the rack plate downward along the vertical sliding mouth. Affected by the meshing connection relationship between the rack plate and the semi-toothed ring, the clamping plate will be tilted upward with the pin rod as the center of the circle. When the personnel place the four corners of the underwear under each clamping plate, when the personnel releases the dial, the rack plate will move up and reset along the vertical rod under the elastic potential energy of the first spring. The clamping plate will rotate and reset due to the transmission action of the semi-toothed ring to press the underwear on the top of the track plate, thereby ensuring the stability of the subsequent underwear filling and sewing work.

[0019] 2. When the dial cylinder is reset and moved upward to the uppermost end of the vertical sliding mouth, the dial cylinder will automatically reset longitudinally under the influence of the elastic potential energy of the second spring, so that the limit ring will re-enter the interior of the limit groove to realize the vertical limit of the dial cylinder. The rubber gasket can produce a certain elastic deformation while protecting the underwear from being crushed, thereby providing a certain elastic displacement compensation for the upward reset of the dial cylinder, so that the limit ring can normally enter the interior of the limit groove, which can indirectly realize the locking limit of the clamping plate while ensuring the convenience of personnel operation, thereby improving the effect of underwear fixing.

[0020] 3. Then, through the regulation of the controller, the electric push rod extends to the right to move the filling frame to the right. When the servo motor drives the screw to rotate, the movable plate will move to the right under the influence of the threaded connection between the screw and the movable plate, and further expand the right movement range of the filling frame. After the air injection tube is inserted into the sponge lining filling cavity on the underwear, the air supplied by the external air pump can inflate the sponge lining filling cavity on the underwear through the air injection tube, so that the filling frame can be normally inserted into the opening of the sponge lining filling cavity. Then, the six-axis manipulator is operated to pick up the sponge lining in the external storage device and stuff it into the interior of the underwear through the filling frame, so as to automatically complete the automatic filling of the underwear filler. Then, the six-axis manipulator and the electric push rod are reset, and the sewing machine can carry out the final underwear filling sewing work. The automatic filling and sewing of the underwear filler has a high degree of automation. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The working principle of the automatic filling and sewing machine for underwear provided by the present invention is as follows: when filling and sewing underwear, the personnel first place the underwear between the upper surfaces of the two track plates 5 and ensure that the filling position of the sponge lining is located directly below the sewing machine 2. Then the personnel manually press the dial cylinder 809 to make it overcome the elastic force of the second spring 813 and appropriately retract into the interior of the hollow box 801. At this time, the limiting ring 812 will move out from the inside of the limiting groove 811 to release the vertical limit of the dial cylinder 809. Then the personnel manually overcome the elastic force of the first spring 810 and move the dial cylinder 809, the protruding rod 807 and the gear along the vertical sliding mouth 808. The strip plate 806 moves downward together, and under the influence of the meshing connection between the rack plate 806 and the semi-toothed ring 804, the clamping plate 803 will tilt upward with the pin rod 802 as the center of the circle. When the personnel puts the four corners of the underwear under each clamping plate 803, when the personnel releases the dial cylinder 809, under the influence of the elastic potential energy of the first spring 810, the rack plate 806 will move up and reset along the vertical rod 805, and the clamping plate 803 will rotate and reset due to the transmission action of the semi-toothed ring 804 to press the underwear on the top of the track plate 5, and when the dial cylinder 809 resets and moves up to the uppermost end of the vertical sliding port 808, the dial cylinder 809 is affected by the elastic potential energy of the second spring 813. The locking ring 812 is automatically reset longitudinally when the button 809 is in the state of being pressed, so that the limiting ring 812 can enter the limiting groove 811 again to realize the vertical limit of the cylinder 809, thereby improving the effect of fixing the underwear. The rubber gasket 814 can undergo a certain elastic deformation while protecting the underwear from being crushed, thereby providing a certain elastic displacement compensation for the upward reset of the cylinder 809, so that the limiting ring 812 can normally enter the limiting groove 811. Subsequently, through the regulation of the controller 7, the electric push rod 12 extends to the right to make the loading frame 13 move to the right. When the servo motor 16 drives the screw 15 to rotate, the screw 15 is connected to the movable plate 11 by the threaded connection. The movable plate 11 will move to the right and further expand the rightward movement range of the filling frame 13. After the air injection tube 14 is inserted into the sponge lining filling cavity on the underwear, the air supplied by the external air pump can inflate the sponge lining filling cavity on the underwear through the air injection tube 14, so that the filling frame 13 can be normally inserted into the opening of the sponge lining filling cavity. Then the six-axis manipulator 6 operates to pick up the sponge lining in the external storage device and stuff it into the interior of the underwear through the filling frame 13, so as to automatically complete the automatic filling of the underwear filler. Then the six-axis manipulator 6 and the electric push rod 12 are reset and the sewing machine 2 can carry out the final underwear filling sewing work.
