The sponge head 61 moves downward under the action of the fifth lifting cylinder 62 and enters the cylinder 81. When the sponge head 61 is in contact with the inner wall of the cylinder 81, the mold release agent can be applied to the inner wall of the cylinder 81. A headrest gate 8 collection box is provided below the fourth station 16. When the headrest gate 8 completes the last step of the process, it directly falls into the headrest gate 8 collection box.

[0039] (2) Detach the bag on the headrest gate 8 downward through the bag removing mechanism 2, and pull out the waste material in the headrest gate 8 upward through the pulling out mechanism 3; the first lifting cylinder 21 drives the first clamping cylinder 22 to rise. When the first chuck 23 rises to the designated position, the first clamping cylinder 22 drives the first chuck 23 to close and clamp the bag on the headrest gate 8, then the first lifting cylinder 21 drives the first clamping cylinder 22 to descend, and finally the first chuck 23 detaches the bag downward from the headrest gate 8; the second lifting cylinder 34 drives the second clamping cylinder 33 to descend. When the second chuck 32 descends to the designated position, the second clamping cylinder 33 drives the second chuck 32 to close and clamp the waste material in the headrest gate 8, then the first motor 35 drives the second clamping cylinder 33 to rotate and at the same time the second lifting cylinder 34 drives the second clamping cylinder 33 to rise, and finally the second chuck 32 pulls out the waste material upward from the headrest gate 8;

[0043] (6) Lift the bag upward through the bagging mechanism 5 and put it on the headrest gate 8; the traction module 52 traction the material tape to unwind it in the unwinding module 51. After the material tape extends upward by a specified length, the third chuck 544 of the bagging module 54 clamps the upper end of the material tape while the cutting module 53 cuts the material tape. The vacuum suction cups on the inner sides of the two third clamping pieces 5441 respectively adsorb both sides of the bag. The third chuck 544 opens to open the bag mouth. The fourth lifting cylinder 541 drives the third chuck 544 to rise. The third chuck 544 puts the bag on the headrest gate 8. The vacuum suction cup 5442 releases the bag.
