[0022] Furthermore, baffles 19 are respectively provided at both ends of the inner wall of the mounting shell 8 to block the sliding of the second movable seat 16. The baffle 19 is fixedly connected to the mounting shell 8 by countersunk bolts. The baffle 19 is formed with a countersunk hole that is compatible with the countersunk bolt. By setting the baffle 19, the movement of the second movable seat 16 to one side is limited, and at the same time, the limit rod 36 is aligned with one of the limit holes 20, preparing for the subsequent insertion of the limit rod 36 into the limit hole 20, that is, preparing for the movement of the second movable seat 16 to both sides to be limited.
[0023] Furthermore, a touch switch 33 is provided at the upper end of the second movable seat 16, which is pressed by the deflection plate 14 when it is opened.

Figure 1 Convert to Instruction Manual Figure 2 For further information, please refer to the instruction manual. Figure 8 ) The deflection of the deflection plate 14 will gradually squeeze the touch pressure switch 33. After being squeezed, the touch pressure switch 33 will feed back a signal to the controller of the external air supply device, and the controller will control the external air supply device to turn on. Conversely, when the deflection plate 14 is gradually retracted from the unfolded state, the deflection of the deflection plate 14 will gradually release the squeezing of the touch pressure switch 33, and then the external air supply device will be turned off, thereby achieving the effect of automatic opening and closing of the purge component.
[0024] Working principle: Blow and clean the body in white: first, the electric push rod 4 is in a retracted state, that is, there is a distance between the frame 2 and the body in white, leaving enough space for the purge component to unfold, and then the second motor 9 rotates forward to drive the second screw rod 15 to rotate, and the rotation of the second screw rod 15 will drive the threaded barrel 26 to rotate (because the purge component is in the storage state, the limit rod 36 is inserted into the limit hole 20, which limits the movement of the second movable seat 16, so the rotation of the second screw rod 15 will not drive the threaded barrel 26 to move under the action of the threaded connection), the rotation of the threaded barrel 26 drives the sliding block 24 to move under the action of the threaded connection, the movement of the sliding block 24 drives the rack 30 to move, the movement of the rack 30 under the meshing action of the tooth block makes the gear 31 rotate, the rotation of the gear 31 drives the rotating shaft 25 to rotate, the rotation of the rotating shaft 25 drives the deflection plate 14 to deflect, and the deflection plate 1 4 deflects and then drives the vertical plate 17 and the air injection pipe 18 to unfold, that is, the purge assembly changes from the storage state to the unfolded state, and the deflection plate 14 deflects and squeezes the touch switch 33, so that the purge assembly starts to work, and then with the movement of the sliding block 24, the groove 37 at the lower end of the sliding block 24 will gradually align with the pressure block 34, and then under the reset action of the compression spring 35, the pressure block 34 will rebound into the groove 37, and the limiting rod 36 will be separated from the limiting hole 20, that is, the restriction on the second moving seat 16 is released, and at this time, the first spring 28 and the second spring 29 are both in the reset state, and the second screw rod 15 continues to rotate to drive the threaded cylinder 26 to move through the threaded connection, and then drive the second moving seat 16 to move, that is, drive the purge assembly to move, so as to achieve the effect of comprehensive purge of the white body hemming operation area; When the second movable seat 16 moves to the other side of the mounting shell 8 (refer to the attached manual Figure 4 And the instruction manual Figure 5 , that is, the second movable seat 16 moves from the right side of the mounting shell 8 to the left side of the mounting shell 8). When the second movable seat 16 abuts against the baffle 19 on the left side of the mounting shell 8, the movement of the second movable seat 16 to the left is restricted, and then the second screw rod 15 continues to rotate, which drives the threaded barrel 26 to rotate. The rotation of the threaded barrel 26 drives the sliding block 24 to move to the left through the threaded connection. The leftward movement of the sliding block 24 squeezes the first spring 28, and the movement of the sliding block 24 drives the rack 30 to move. Under the meshing action of the tooth block, the gear 31 rotates, and the rotation of the gear 31 passes The deflection plate 14 is driven to rotate by the rotation shaft 25, so that the purge assembly is stored on the other side of the frame 2. In this process, the deflection plate 14 will release the squeeze on the touch switch 33, so that the purge assembly automatically stops working. The sliding of the sliding block 24 will squeeze the pressure block 34, so that the limiting rod 36 is inserted into the limiting hole 20, and the left and right movement of the second movable seat 16 is limited. As the sliding block 24 slides, the sliding block 24 will be separated from the threaded ring on the surface of the threaded barrel 26, that is, after the purge assembly is stored in place, the second screw rod 15 continues to rotate without causing interference. Perform the rolling operation: first, the electric push rod 4 starts the movement of the mold frame 2, so that the mold base 5 contacts the white body, and then starts the first motor 7, the first motor 7 drives the first screw rod 13 to rotate, the rotation of the first screw rod 13 drives the first movable seat 12 to move, the movement of the first movable seat 12 drives the rectangular frame 10 to move, under the coordinated action of the vertical slider 21 and the guide slider 22, the vertical slider 21 slides along the rectangular frame 10, and the guide slider 22 slides along the guide groove 6, thereby carrying the rolling assembly 23 to move around the mold base 5 to complete the rolling operation.
