The support rods 12, the base 11, and the first width adjustment component cooperate to form a... The frame for accommodating cardboard boxes; the box rack mechanism in this technical solution is used to place unopened cardboard boxes. The box opening robot picks up the cardboard boxes on the box rack mechanism and flips them over, performing the opening action during the flipping process. The feeding mechanism aligns with the opened cardboard boxes and pushes the material into the boxes. Then, the cardboard boxes enter the push-close mechanism for closing the inner and outer flaps, and finally enter the discharge mechanism. In addition, the box rack mechanism in the case packing machine can not only store cardboard boxes but also adjust its width and height to accommodate the picking and storing of cardboard boxes of different sizes, improving the versatility of the box rack mechanism and increasing work efficiency. Moreover, the height adjustment component has a worm gear self-locking function, making it very convenient to adjust and lock at any time. It has the advantages of good working stability and practicality.

After that, the opening robot closes the inner flap on one side of the cardboard box. In addition, the discharging mechanism is a roller structure. The cardboard box with the box is pushed onto the discharging mechanism by the box-closing mechanism, and then proceeds to the next process. The feeding mechanism and the discharging mechanism are both existing technologies, and will not be described in detail here.

[0092] The first width adjustment component includes:

[0093] Several first supports 13 are arranged side by side and symmetrically on both sides of the base 11;

[0094] The first adjusting rod 14 passes laterally through all the first brackets 13 in sequence;

[0095] The first bracket 13 is provided with a nut block 131, and the first adjusting rod 14 is provided with a positive thread (not shown) and a negative thread (not shown) that are threadedly engaged with the nut block 131.

[0097] The first support 13 is equipped with a railing 132, which is used to limit the sides of the carton to ensure that the carton is stacked neatly.

[0098] The first support 13 has rollers 133 at its front and rear ends and belts 134 mounted on the rollers 133. The front end of the first support 13 has a rotatably mounted swing arm 135 and a feeding drive 136 that drives the swing arm 135 to swing back and forth. A linkage shaft 137 is provided between the rollers 133 and the swing arm 135 to link the two. A one-way bearing 138 is provided between the linkage shaft 137 and the swing arm 135. The piston end of the feeding drive 136 is hinged to the end of the swing arm 135, and the tail end of the feeding drive 136 is hinged to the first support 13. The feeding drive drives the swing arm to swing. When the swing arm swings, it drives the rollers to rotate in one direction through the one-way bearing and the linkage shaft. Each time the swing arm swings, the rollers will rotate at an appropriate angle, so that the belt drives the carton forward rhythmically.

[0099] The first bracket 13 has a support plate 15 located below the front of the roller 133. The support rod 12 has a clamp 16 with an adjustable vertical position. The clamp 16 has a pressure roller 161 that is rotatably mounted and corresponds to the support plate 15. When the carton moves under the roller, it will fall onto the support plate below, and the rolling action provides guidance.

[0100] The clamp 16 is provided with a pressure member 162 located in front of the pressure roller 161 to flatten the cartons. The cartons falling on the pallet may be uneven in height. By setting the pressure member to provide pressure to the cartons, all the cartons are kept at the same height.
