On block 20, the other end is fixed on the bottom of lifting seat 4；14 side of the fixed seat is additionally provided with that a promotion lifting seat moves down
The end of two air rammers 10, the second air rammer is located at right over 4 bottom of lifting seat.There is air flue in fixed seat, to fixed seat
Ventilation, which makes the second air rammer 10 act on lifting seat 4, makes it move down, and when stuffiness, lifting seat 4 leans on lifting drawspring
24 resets move upwards.
Original state, lifting seat 4 are in extreme higher position, and gripper roller 8 is stuck in revolution block 20, then to fixed seat 14
Ventilation so that 10 end of the second air rammer overcomes the elastic force of lifting drawspring 24 and the resistance of revolution block 20 to push lifting seat 4
It moves down；Meanwhile when gripper roller 8 skids off revolution block 20, gripper seat 2 drives gripper under the action of compression spring 22
3 are swung out centered on gripper seat rotating shaft 5, and the elastic portion that 23 script of control panel is extruded can also reset, and push out
Gripper seat 2 makes gripper 3 enter fabric 25 and completes drawing action, until gripper Roller Shaft 7 is limited by long slot bore.
When gripper is detached from fabric 25, needs first to ventilate to linear bearing seat 6, the first air rammer 21 is made to push forward
23 bottom of control panel so that 23 head of control panel overcomes the elastic force of compression spring 22, is inwardly swung centered on gripper seat rotating shaft 5,
It drives gripper seat 2 inwardly to swing, then stops ventilating to fixed seat 14, lifting seat 4 drives 2 answering with lifting drawspring 24 of gripper seat
Position up moves；After gripper roller 8 slides into revolution block 20, the elastic portion of control panel 23 is tightly against control panel roller 15
On, compression spring 22 is in compressive state, stops ventilating to linear bearing seat 6, and gripper 3 is limited by turning round block 20, is detached from fabric and returns
To starting shape.
