The third transmission mechanism 33 drives the third suction member 31 to move toward the storage position for the article 104 to absorb the article 104. The third transmission mechanism 33 then drives the third suction member 31 and the absorbed article 104 to move toward the box body 102, thereby placing the article 104 inside the box body 102.

[0134] The packaging box 100 moves from the second station to the third station. During this process, the second support member 62 supports the box cover 101 so that the box cover 101 is in an open state.

[0135] refer to Figure 5 The packaging box 100 moves to the third station, where the third support member 63 supports the lid 101 from outside. First, the first lever 41 is rotated, raising one end of the lever 41 upward, lifting the first portion of the wrapping paper 103 outside the box body 102. The second lever 42 then moves below the first portion of the wrapping paper 103 and along the conveying direction of the conveyor assembly 5, ensuring that the first portion of the wrapping paper 103 covers the article. The air jet 46 then blows air toward the outside of the lid 101, closing it.

[0136] refer to Figure 6 After the packaging box 100 continues to be transported from the third station to the fourth station through the conveying assembly 5, the pressing assembly 7 presses against the top of the box cover 101 to close the box cover 101 tightly.

[0137] When a qualified package 100 passes through the capping assembly 7, the capping assembly 7 presses against the top of the lid 101 to tightly close the lid 101. When an unqualified package 100 passes through the capping assembly 7, the rejecting element 81 rejects the unqualified package 100. The qualified package is transported to the subsequent equipment via the conveyor belt.
