[0040] The working principle and use process of the present invention:

[0041] First, the first cylinder 2 pushes the fixing block 3 to move along one side of the traction frame 1, and the fixing block 3 drives the fixing frame 4 to move. When the fixing frame 4 moves to the top of the polyurethane foam, the second cylinder 6 pushes the first traction plate 711 to move, and the first traction plate 711 drives the traction vertical rod 712 to move, so that the traction vertical rod 712 pushes the second traction plate 713 to move along the inner wall of the traction ring 714 until the bottom of the first traction plate 711 abuts against the traction ring 714;

[0042] During the movement of the second traction plate 713, the second traction plate 713 drives the second traction assembly 10 to move until the bottom end of the rubber cotton 1014 is flush with the bottom of the polyurethane foam. At this time, the third cylinder 9 pulls the moving plate 8 so that the moving plate 8 slides along the inside of the second traction plate 713, and the moving plate 8 drives the traction block 1011 to move. At this time, the traction block 1011 drives the rubber cotton 1014 to slide along the bottom of the second traction plate 713 through the traction screw 1012;

[0043] During the movement of the rubber cotton 1014, the traction block 1011 drives the fixed shaft 1111 to move. At this time, the fixed shaft 1111 is meshed with the gear 1112 to rotate the gear 1112, so that the gear 1112 is meshed with the first rack 1113 and drives the first rack 1113 and the fixed shaft 1111 to move in the opposite direction. At this time, the first rack 1113 drives another traction block 1011 to move, so that the two groups of traction blocks 1011 move toward each other.

[0044] Until the rubber cotton 1014 clamps the polyurethane foam, the second cylinder 6 pulls the first traction assembly 7 in the opposite direction to move the polyurethane foam away from the original position, and the first cylinder 2 pulls the fixed frame 4 in the opposite direction to place the polyurethane foam for the second time, thus completing the operation.
