[0026] It should be noted that the running directions of the first conveyor belt 101 and the second conveyor belt 102 are opposite. Similarly, the printing directions of the first printing machine 103 and the second printing machine 104 are also opposite and are respectively consistent with the first conveyor belt 101 and the second conveyor belt 102; the rectifying component 11 is located at the end of the conveying position on the first conveyor belt 101 and is responsible for rectifying the packaging box that has been printed on one side to a position suitable for entering the rectangular frame 121. The rectifying component 11 is located at the head of the conveying position on the second conveyor belt 102 and is responsible for rectifying the packaging box entering the second conveyor belt 102 to a position suitable for secondary printing;

[0027] Furthermore, before printing the packaging box, the threaded rod 114 is shaken respectively through the crank 115, so that the arc-shaped frames 112 of the same group are adjusted relative to the strip-shaped frame to limit the distance, and the two arc-shaped frames 112 at the tail of the first conveyor belt 101 are adjusted to a position suitable for the packaging box to enter the rectangular frame 121, and the two arc-shaped frames 112 at the head of the second conveyor belt 102 are adjusted to a position suitable for the packaging box to enter below the second printing machine 104;

[0028] Furthermore, the unprinted packaging box is accurately placed above the head of the first conveyor belt 101 through an external device or manually, and the first conveyor belt 101 drives the packaging box to enter the first printing machine 103 for single-sided printing;

[0029] Furthermore, the first conveyor belt 101 drives the single-sided printed packaging box to enter the rectangular frame 121 under the position adjustment of the rectifying component 11, and after being flipped, it enters the head position of the second conveyor belt 102;

[0030] Further, the packaging boxes after single-sided printing all enter the head end of the second conveyor belt 102 under the position adjustment of the correction component 11, enter under the second printing machine 104 to be printed under the drive of the second conveyor belt 102, and continue to pass outside the output device of the second printing machine 104.

[0031] Please refer specifically to Appendix Figure 1 、 4 As shown in Figure 5, the storage component 12 includes two rectangular frames 121 respectively arranged outside the same end of the first conveyor belt 101 and the second conveyor belt 102, multiple groups of limiting frames 122 arranged at the upper and lower ends of the rectangular frames 121, and multiple rollers 123 rotatably installed in the middle of the limiting frames 122; the loading component 13 includes a first support plate 131 arranged in the middle of the first conveyor belt 101 and the second conveyor belt 102, a second support plate 132 arranged at one end of the two rectangular frames 121 away from the printing component 10, and a connecting pile 133 rotatably installed in the middle of the first support plate 131 and the second support plate 132 and connecting the opposite sides of the two rectangular frames 121; the driving component 14 includes a right-angle reduction gear 141 arranged at one end of the second support plate 132 away from the printing component 10 and with its output end connected to the central axis of the connecting pile 133, a driving motor 142 with its execution end connected to the input end of the right-angle reduction gear 141, and a pressure sensor 143 arranged at the corresponding position near one end of the second support plate 132 close to the first conveyor belt 101.

[0032] It should be noted that the position for entering and exiting the rectangular frame 121 is parallel to the upper surface of the belts of the first conveyor belt 101 and the second conveyor belt 102. The distance between the middles of two rollers 123 at the corresponding upper and lower positions is slightly larger than the thickness of the packaging box. The second support plate 132 needs to have sufficient height, and its supporting position needs to ensure that the two rectangular frames 121 do not touch the ground when rotating. The driving motor 142 is a stepping motor controlled by programming software and is driven by the pressure sensor 143 as an electrical signal.

[0033] Further, the packaging box enters the rectangular frame 121 under the drive of the first conveyor belt 101 until it completely enters the multiple rollers 123 in the middle of the limiting frames 122.

[0034] Further, the packaging box gently hits the pressure sensor 143 under the drive of the first conveyor belt 101, and the pressure sensor 143 triggers and transmits an electrical signal to start the driving motor 142.

[0035] Further, the driving motor 142 starts to rotate, drives the connecting pile 133 to rotate 180° in the middle of the first support plate 131 and the second support plate 132 through the right-angle reduction gear 141, and then drives the two rectangular frames 121 to exchange positions, so that the packaging box is flipped 180° and reaches the head end of the second conveyor belt 102 from the tail end of the first conveyor belt 101.

[0036] Further, after the connecting pile 133 rotates 180°, the driving motor 142 pauses and waits for the electrical signal of the pressure sensor 143.

[0037] Please refer specifically to Appendix Figure 1 , 4 , as shown in Figure 5, the pushing member 15 includes a mounting frame 151 provided at a corresponding position at one end of the second support plate 132 away from the second conveyor belt 102, two telescopic rods 152 provided inside the mounting frame 151, and a pushing plate 153 provided at the execution ends of the two telescopic rods 152.

[0038] It should be noted that the length of the rectangular frame 121 should be less than the length of the packaging box, so that the packaging box can hit the pressure sensor 143 driven by the first conveyor belt 101, and one end surface can also be placed on the belt surface of the second conveyor belt 102 after being flipped 180°. There is a rectangular groove on the second support plate 132 to adapt to the operation of the pushing member 15. In order to prevent insufficient friction on the belt surface of the second conveyor belt 102, the pushing member 15 is added as a boost in this embodiment;

[0039] Further, when the driving motor 142 pauses and waits for the electrical signal of the pressure sensor 143, the two telescopic rods 152 extend, driving the pushing plate 153 to push the packaging box in the rectangular frame 121, so that it all enters the belt surface of the second conveyor belt 102 under the rolling of multiple rollers 123;

[0040] Further, before the pressure sensor 143 issues the next electrical signal, the two telescopic rods 152 quickly retract with the pushing plate 153 to prevent affecting the flipping process.

[0041] The working principle of the present utility model is:

[0042] First, before printing the packing box is needed, the threaded rod 114 is shaken by the crank 115 respectively, so that the arc-shaped frames 112 of the same group adjust the limit distance relative to the strip-shaped frame, and the two arc-shaped frames 112 at the tail of the first conveyor belt 101 are adjusted to a position suitable for the packing box to enter the rectangular frame 121, and the two arc-shaped frames 112 at the head of the second conveyor belt 102 are adjusted to a position suitable for the packing box to enter under the second printing machine 104. The unprinted packing box is accurately placed above the head end of the first conveyor belt 101 through external equipment or manually. The first conveyor belt 101 drives the packing box into the first printing machine 103 for single-sided printing. The first conveyor belt 101 drives the single-sided printed packing box to enter the rectangular frame 121 under the position adjustment of the correction component 11 until it all enters the plurality of rollers 123 in the middle of the limit frame 122. The packing box gently hits the pressure sensor 143 under the drive of the first conveyor belt 101. The pressure sensor 143 triggers and transmits an electrical signal to start the drive motor 142. The drive motor 142 starts to rotate, drives the connecting pile 133 to rotate 180° in the middle of the first support plate 131 and the second support plate 132 through the right-angle reduction gear 141, and then drives the two rectangular frames 121 to exchange positions, so that the packing box is turned over 180° and arrives at the head end of the second conveyor belt 102 from the tail end of the first conveyor belt 101. After the connecting pile 133 rotates 180°, the drive motor 142 pauses and waits for the electrical signal of the pressure sensor 143; when the drive motor 142 pauses and waits for the electrical signal of the pressure sensor 143, the two telescopic rods 152 extend, drive the push plate 153 to push the packing box in the rectangular frame 121, so that it all enters the belt surface of the second conveyor belt 102 under the rolling of the plurality of rollers 123. Before the pressure sensor 143 issues the next electrical signal, the two telescopic rods 152 drive the push plate 153 to quickly retract to prevent affecting the turning process. The single-sided printed packing box all enters the head end of the second conveyor belt 102 under the position adjustment of the correction component 11, enters under the second printing machine 104 for printing under the drive of the second conveyor belt 102, and continues to pass outside the output device of the second printing machine 104.

[0043] The above embodiments are only used to illustrate the technical idea of the present invention, and the protection scope of the present invention cannot be limited thereby. Any modification made on the basis of the technical solution according to the technical idea proposed by the present invention falls within the protection scope of the present invention.
