An intermediate conveying mechanism 43 is provided between the conveying platform 42 and the box turning device 3. The conveying platform 42 is docked with the turning conveying mechanism 61. The intermediate conveying mechanism 43 conveys the boxes 13 conveyed by the box turning device 3 (turret 32) to the conveying platform 42, and pushes the boxes 13 on the conveying platform 42 forward, so that the boxes 13 on the conveying platform 42 are closely adjacent to each other front and back, preventing the orientation of the boxes 13 on the conveying platform 42 from changing, which is convenient for the first film sealing mechanism 41 and the second film sealing device 5 to accurately heat-seal the corresponding sides of the boxes 13. The first film sealing mechanism 41 is used to heat-seal the films on the left and right sides of the boxes 13 on the conveying platform 42 that are open, and the second film sealing device 5 is used to heat-seal the upper and lower sides of the boxes 13 on the conveying platform 42.

[0040] Preferably, the turning and conveying mechanism 61 is a pushing mechanism for pushing the film conveyed at the discharging end of the conveying platform 42 (also the film conveyed at the discharging end of the second film sealing device 5) to the third film sealing mechanism 62, so that the box 13 accurately reaches the film sealing position of the third film sealing mechanism 62, and the front and back sides (the left and right sides in the pushing direction of the pushing mechanism) of the box body 13 are heat-sealed by the third film sealing mechanism 62. The six-side film sealing of the box body 13 is carried out in sequence, which is beneficial to improving the overall film sealing effect and the overall production efficiency.

[0043] It should be noted that: the box body 13 is a hexahedron structure (cube structure), and the left and right, up and down, and front and back do not specifically refer to specific directions, but only relative directions. The box body 13 has three pairs of opposite sides. The left and right sides of the box body 13 are the first pair of opposite sides of the box body 13, the left and right sides of the box body 13 are the second pair of opposite sides of the box body 13, and the up and down sides of the box body 13 are the third pair of opposite sides of the box body 13. Of course, in this embodiment, the left and right sides of the box body 13 can refer to the left and right sides along the conveying direction of the straight line 7, the up and down sides of the box body 13 can refer to the up and down sides along the conveying direction of the straight line 7, and the front and back sides of the box body 13 can refer to the front and back sides along the conveying direction of the straight line 7.

[0044] It should be further noted that in this embodiment, the box feeding device 1, the film feeding device 2, the box turning device 3, the first film sealing device 4 and the second film sealing device 5 are arranged in sequence along the straight line 7. It does not specifically mean that the box feeding device 1, the film feeding device 2, the box turning device 3, the first film sealing device 4 and the second film sealing device 5 must be strictly arranged in sequence along the straight line 7. It only means that the overall conveying direction of the box feeding device 1, the film feeding device 2, the box turning device 3, the first film sealing device 4 and the second film sealing device 5 is along the direction of the straight line 7 (for example, the turret 32 conveys the box 13 along an arc, but the overall moving direction of the box 13 is also along the direction of the straight line 7). Therefore, the box feeding device 1, the film feeding device 2, the box turning device 3, the first film sealing device 4 and the second film sealing device 5 can be arranged on the straight line 7 or at the upper and lower positions of the straight line 7 according to specific situations.
