[0024] The packaging box to be flattened is placed on the conveyor belt 2. When the packaging box moves between the two push plates 10, the control component drives the push plates 10 to move toward each other through the connecting rod 9 to flatten the left and right folding plates of the packaging box. The conveyor belt 2 drives the packaging box to move under the pressure rod 15. The control component drives the pressure rod 15 to move downward at an angle to flatten the front folding plate of the packaging box. The continuous transportation of the conveyor belt 2 drives the packaging box to fit with the baffle 19. Under the action of the baffle 19, the rear folding plate of the packaging box can be flattened, thereby completing the flattening of the folding plate of the packaging box. The structure is simple, the rapid flattening of the packaging box is realized, the processing efficiency is improved, and the practicability is strong.

[0025] Reference Figure 1 and Figure 2 The control component includes a rotating shaft 4 rotatably connected to the middle of the support plate 3, a gear 5 fixedly connected to the outside of the rotating shaft 4, two racks 8 slidably connected to the top of the support plate 3 and both meshing with the gear 5, a fixing frame 6 fixedly connected to the top of the support plate 3 and a motor 7 fixedly connected to the top of the fixing frame 6. The top of the rotating shaft 4 is fixedly connected to the output shaft of the motor 7, and the ends of the two connecting rods 9 opposite to the push plate 10 are meshing with the adjacent racks 8. The operation of the motor 7 drives the rotating shaft 4 to rotate and drives the gear 5 to rotate at the same time. The movement operation of the rack 8 can be realized by the rotating gear 5. When the rack 8 moves, the push plate 10 can be driven to move toward each other through the connecting rod 9, so that the left and right folding plates of the packaging box can be flattened under the action of the push plates 10 moving toward each other.

[0026] Reference Figure 1 , Figure 2 and Figure 4The driving assembly includes two guide grooves 12 opened inside the box body 1 and inclined downwardly arranged toward one side of the baffle 19, two sliders 13 slidably connected to the corresponding guide grooves 12, a fixed plate 16 fixedly connected to one side of the fixing frame 6, an electric push rod 17 fixedly connected to the top of the fixed plate 16, and a connecting plate 18 rotatably connected to the bottom of the piston rod of the electric push rod 17. The adjacent ends of the two sliders 13 are rotatably connected to the end of the pressure rod 15, and a connecting block is fixedly connected to the middle part of the top side of the pressure rod 15. The bottom of the connecting plate 18 is rotatably connected to the connecting block. After the folding plates on the left and right sides of the packaging box are flattened, they move to the bottom of the pressure rod 15. The electric push rod 17 runs through the connecting plate 18 to drive the pressure rod 15 to move downward, and while the pressure rod 15 moves downward, it drives the slider 13 inside the guide groove 12, so that the downward-moving pressure rod 15 can be tilted and moved downward, thereby flattening the front side folding plate of the packaging box.

[0027] Reference Figure 3 The two push plates 10 are fixedly connected to one side of the adjacent connecting rod 9 with a screw rod 20, and the two screw rods 20 are connected to the internal threads of the adjacent connecting rod 9. By rotating the push plates 10, the screw rods 20 are driven to rotate inside the connecting rod 9, so that the distance between the two push plates 10 can be better adjusted to suit packaging boxes of different widths for flattening the folding plates.

[0028] Reference Figure 1 and Figure 2 A limit plate 11 is fixedly connected to the top of the support plate 3 and located on the side where the rack 8 and the gear 5 are separated. The two racks 8 are slidably connected to the corresponding limit plates 11. When the gear 5 rotates to drive the rack 8 to move left and right, it is slidably connected with the limit plate 11, which is beneficial to ensure the stable meshing connection between the rack 8 and the gear 5.

[0029] Reference Figure 1 , Figure 2 and Figure 4 The two ends of the two sliders 13 that are separated from each other are fixedly connected to the limiting blocks 14. The two limiting blocks 14 that slide on the outside of the box body 1 can limit the slider 13 that is slidably connected to the inside of the guide groove 12 to ensure the stability of the movement of the pressure rod 15.

[0030] Working principle: the packaging box to be flattened is placed on the conveyor belt 2. When the packaging box moves between the two push plates 10, the motor 7 drives the rotating shaft 4 to rotate and drives the gear 5 to rotate. The rotating gear 5 can realize the movement operation of the rack 8. When the rack 8 moves, the push plates 10 can be driven to move toward each other through the connecting rod 9. Therefore, the left and right folding plates of the packaging box can be flattened under the action of the push plates 10 moving toward each other.

[0031] The conveyor belt 2 drives the packaging box to move under the pressure rod 15, and the electric push rod 17 runs through the connecting plate 18 to drive the pressure rod 15 to move downward. The downward movement of the pressure rod 15 drives the slider 13 inside the guide groove 12, so that the downward moving pressure rod 15 can be tilted and moved downward, thereby flattening the front folding plate of the packaging box. The continuous conveying of the conveyor belt 2 drives the packaging box to fit with the baffle 19, and under the action of the baffle 19, the rear folding plate of the packaging box can be flattened, thereby completing the flattening work of the folding plate of the packaging box. The structure is simple, and the rapid flattening of the packaging box is realized, which improves the processing efficiency and has strong practicality.
