The output end of the movable cylinder 302 is brought into contact with the H-shaped plate 303 with the electric suction cups 304, and the electric suction cups 304 are adsorbed on both sides of the facial mask packaging bag 4. The facial mask packaging bag 4 is pulled open by moving the movable cylinder 302 backwards;

[0066] A mobile driving motor 102 is provided, and the output end of the mobile driving motor 102 drives two groups of threaded screws 104 to rotate along the middle part of the first positioning block 100. The two groups of threaded screws 104 rotate so that the two groups of main moving rods 105 move inward along the main moving groove 101 and the threaded screw 104 through the limitation of the first positioning block 100.

The two sets of sealing blocks 1066 move back and forth to squeeze and heat the opening of the mask packaging bag 4 and finally seal it, which can effectively improve the efficiency and speed of sealing the mask packaging bag 4;

[0068] After sealing, the mobile driving motor 102 is adjusted to reverse, and the output end of the mobile driving motor 102 drives two sets of threaded screws 104 to rotate along the middle of the first positioning block 100. The two sets of threaded screws 104 rotate to make the two sets of main moving rods 105 move outward along the main moving groove 101 and the threaded screw 104 through the limit of the first positioning block 100. The two sets of main moving rods 105 move outward with the connecting block 106, and the other side of the connecting block 106 moves outward with the auxiliary moving rod 108 along the auxiliary moving groove 1071 and the limit column 109. The two sets of connecting blocks 106 move outward with the auxiliary block 1061, the sliding block 1065, and the sealing block 1066;

[0069] The movable cylinder 302 is set in reverse and the electric suction cup 304 is closed, so that the sealed mask packaging bag 4 falls into the discharge plate 12 through the opening component 3, and finally the sealed mask packaging bag 4 slides out from the discharge plate 12 to complete the unloading.

[0070] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
