[0030] The box wrapping system includes a first film sealing device 4, a second film sealing device 5 and a third film sealing device 6, which successively perform film heat sealing on three pairs of opposite sides of the box body 13, so that the six sides of the box body 13 are tightly fitted with the film sheet 14, avoiding the formation of bubbles between the film and the box body 13, and achieving a good film sealing effect.

[0031] Further, 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, and the third film sealing device 6 includes a steering conveying mechanism 61 and a third film sealing mechanism 62, the steering conveying mechanism 61 is connected to the discharge end of the second film sealing device 5, and the third film sealing mechanism 62 is arranged above the steering conveying mechanism 61, and the conveying direction of the steering conveying mechanism 61 is perpendicular to the discharge direction of the second film sealing device 5. Specifically, the discharge direction of the second film sealing device 5 is collinear or parallel to the straight line 7.

[0032] 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, and the third film sealing mechanism 62 is arranged above the turning conveying mechanism 61 which is perpendicular to the discharging direction of the second film sealing device 5, and is not arranged on the straight line 7, so that the first film sealing device 4, the second film sealing device 5 and the third film sealing mechanism 62 are well matched in sequence, and the box body 13 is output from the second film sealing device 5 and enters the turning conveying mechanism 61, and the front and rear directions of the box body 13 in the conveying direction of the second film sealing device 5 are changed into the left and right directions in the conveying direction of the turning conveying mechanism 61, so that the third film sealing mechanism 62 can perform front and rear film sealing, that is, left and right film sealing in the conveying direction of the turning conveying mechanism 61, so that the third film sealing mechanism 62 and the first film sealing device 4 can be set to the same structure, which reduces the manufacturing cost. At the same time, the overall structure is reasonably arranged and occupies a small space.

[0033] Furthermore, in this embodiment, the box wrapping system further includes a mounting frame 8, 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 all installed on one side of the mounting frame 8, and the steering conveying mechanism 61 is located at one end of the mounting frame 8. In other words, the box feeding device 1, the film feeding device 2, the box turning device 3, the first film sealing device 4, the second film sealing device 5 and the steering conveying mechanism 61 are sequentially arranged along the edge of the mounting frame 8, and the overall structure is compact. Specifically, the third film sealing mechanism 62 is located at one end of the mounting frame 8.

[0034] Furthermore, in this embodiment, the box wrapping system further includes a buffer conveyor device 9, which is connected to the feeding end of the box feeding device 1. The buffer conveyor device 9 can be used to buffer the box 13, which can prevent the box 13 from being transported too fast and piled up downstream of the buffer conveyor device 9, and can also buffer the box 13 in advance to avoid untimely supply of materials upstream of the buffer conveyor device 9 and affect the overall production efficiency.

[0035] Furthermore, in this embodiment, the box wrapping system further includes a box output device 10, which is docked with the discharge end of the steering conveying mechanism 61, and a detection device 12 is provided on the box output device 10. The box output device 10 is used to output the six-sided heat-sealed box 13 conveyed from the steering conveying mechanism 61, and detect the box 13 through the detection device 12 to detect the heat sealing effect of the box 13, and the box 13 that does not meet the heat sealing standard is subsequently rejected or re-sealed after the film is removed.

[0036] Furthermore, in this embodiment, the buffer conveying device 9 and the box output device 10 are both parallel to the straight line 7, so as to further improve the rationality of the overall layout.

[0037] Furthermore, in this embodiment, the buffer conveying device 9 and the box output device 10 are co-linear. Specifically, the buffer conveying device 9 and the box output device 10 are respectively located at both ends of the mounting frame 8. The box 13 is transported along three sides of the mounting frame 8, and the overall layout design is ingenious, which not only meets the requirements of compact structure, but also meets the requirements of buffering and six-sided film sealing.

[0038] Furthermore, in this embodiment, a pushing device 11 is provided between the buffer conveying device 9 and the box feeding device 1 for pushing the box 13 on the buffer conveying device 9 to the box feeding device 1. Specifically, the pushing direction of the pushing device 11 is perpendicular to the straight line 7.

[0039] Furthermore, in this embodiment, the first film sealing device 4 includes a first film sealing mechanism 41 and a conveying platform 42. The first film sealing mechanism 41 and the second film sealing device 5 are both located above the conveying platform 42. An intermediate conveying mechanism 43 is provided between the conveying platform 42 and the box body turning device 3. The conveying platform 42 is docked with the steering conveying mechanism 61. The intermediate conveying mechanism 43 conveys the box body 13 conveyed by the box body turning device 3 (turret 32) to the conveying platform 42, and pushes the box body 13 on the conveying platform 42 forward, so that the box body 13 on the conveying platform 42 is close to each other front and back, preventing the box body 13 from changing its orientation on the conveying platform 42, and facilitating the first film sealing mechanism 41 and the second film sealing device 5 to accurately heat-seal the film on the corresponding side of the box body 13. The first film sealing mechanism 41 is used to heat-seal the film on the left and right sides of the box body 13 on the conveying platform 42, and the second film sealing device 5 is used to heat-seal the film on the upper and lower sides of the box body 13 on the conveying platform 42.

[0040] Preferably, the steering conveying mechanism 61 is a pushing mechanism, which is used to push the film conveyed by the discharge end of the conveying platform 42 (also called the film conveyed by the discharge 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 third film sealing mechanism 62 performs heat sealing on the front and back sides (the left and right sides of the pushing direction of the pushing mechanism) of the box body 13. The six sides of the box body 13 are sealed in sequence, which is beneficial to improving the overall film sealing effect and the overall production efficiency.

[0041] Furthermore, in this embodiment, the box body turning device 3 includes a turret 32 ​​and a plurality of box receiving grooves 33 arranged around the turret 32. The film feeding device 2 is used to place the film sheet 14 in front of the box body 13 entering the box body turning device 3, so that after the box body 13 enters the box receiving groove 33 of the turret 32, the three sides of the box receiving groove 33 are pressed to achieve film lamination. The turret 32 ​​rotates to rotate the side of the box receiving groove 33 that is open on three sides relative to the film lamination (the bottom side of the box body 13, the side corresponding to the open side of the box receiving groove 33) to face the bottom film sealing device 31, and the bottom film sealing device 31 seals the bottom film, so that a circle of film lamination is formed outside the box body 13.

[0042] In this embodiment, the box body 13 undergoes a wrapping process of the box body wrapping system as follows: Figure 4 As shown, a1 is the box buffer conveying process, a2 is the process of the box from the buffer conveying device to the box feeding device, a3 is the box conveying process of the box feeding device, a4 is the box conveying process of the box turning device, a5 is the heat sealing process of the box body by the first film sealing mechanism, a6 is the heat sealing process of the box body by the second film sealing device, a7 is the heat sealing process of the box body by the third film sealing device, and a8 is the box conveying process of the box output device.

[0043] It should be noted that the box body 13 is a hexahedral structure (cube structure), and left and right, up and down, and front and back do not specifically refer to specific directions, but only to 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 opposite sides of the box body 13, the left and right sides of the box body 13 are the second opposite sides of the box body 13, and the upper and lower sides of the box body 13 are the third 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 of the box body 13 in the conveying direction of the straight line 7, the upper and lower sides of the box body 13 can refer to the upper and lower sides of the box body 13 in 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 of the box body 13 in the conveying direction of the straight line 7.

[0044] It should be further explained that: in the present 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, which 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 arranged in sequence strictly according to the straight line 7, but 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 (such as the turret 32 ​​conveys the box body 13 along the arc, but the overall moving direction of the box body 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 above and below the straight line 7 according to the specific situation.
