[0002] Cardboard boxes are packaging containers made from materials such as pulp and fiber through mechanical processing and molding. They are widely used in the transportation, storage, and sale of goods. Cardboard boxes generally have good strength, pressure resistance, shock resistance, and environmental friendliness. Cardboard box inserts are an important part of the cardboard box production process. They refer to the use of insertable divider structures to separate the internal space of the cardboard box. This design is common in the packaging industry, especially for packaging needs that protect fragile items or separate multiple small items. Inserts can prevent items from colliding, scratching, or being damaged during transportation, increasing the safety of the packaging.

[0003] Currently, traditional insert mechanisms lack adjustment capabilities, failing to flexibly adjust the number and position of inserts according to different carton sizes, thus limiting their applicability. Furthermore, traditional designs often require manual adjustment or fixing of the inserts, a cumbersome and time-consuming process that cannot achieve fast and precise insertion. The removal of traditional insert heads is also typically inconvenient, requiring manual operation or laborious disassembly. Therefore, this invention proposes a flexible insert head device for cartons to address the problems mentioned in the background section. Summary of the Invention

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 A flexible insert device for cardboard boxes includes an assembly base 1. A positioning plate 2 is fixedly installed on the lower part of the assembly base 1. A plurality of plug sockets 3 are provided between the positioning plate 2 and the assembly base 1. The length of the positioning plate 2 is equal to the length of the assembly base 1. A notch is preset between the outer end of the positioning plate 2 and the assembly base 1. The plug sockets 3 enter between the positioning plate 2 and the assembly base 1 through the preset notch. The plug sockets 3 slide left and right between the positioning plate 2 and the assembly base 1. According to the number of inserts required, an appropriate number of plug sockets 3 are selected and inserted. The plug sockets 3 enter between the positioning plate 2 and the assembly base 1 through the preset notch.

[0024] A slide is fixed on the upper side of the plug socket 3. The slide is sleeved on the upper side of the positioning plate 2. The slide is threaded with a positioning stud 10 corresponding to the positioning plate 2, and the slide has a screw hole corresponding to the positioning stud 10. According to the spacing of the plug slots, the distance between adjacent plug sockets 3 can be adjusted reasonably. By loosening or tightening the positioning stud 10 on the slide, the position of the plug socket 3 on the assembly base 1 can be quickly adjusted and fixed.

[0025] A rotating sleeve 7 is rotatably connected to the center of the plug socket 3. Slides 4 are provided on both the left and right sides of the plug socket 3, sliding left and right on the plug socket 3. A corresponding rectangular rod 8 is rotatably connected to the upper side of the slide 4, sliding inward and outward within the corresponding rotating sleeve 7. A rotating chuck 5 is fixed to the outer end of the rectangular rod 8, located outside the slide 4. Another rotating chuck 5 is provided on one side of the rotating chuck 5, rotatably connected to the corresponding slide 4. A sponge pad 6 is provided on the outer side of the rotating chuck 5. A spur gear 9 is fixed to the upper connecting part of the rotating chuck 5. The spur gears on the two rotating chucks 5 outside the slide 4 are... The gears 1 and 9 mesh with each other. By rotating the outer side of the slide block 4, the other chuck 5 can be rotated in the opposite direction through the two meshing spur gears 1 and 9. After the two chucks 5 on the outer side of the slide block 4 are inserted into the same slot, the slot is loaded into the carton. When it is necessary to remove the slot structure from the carton, the two chucks 5 need to be rotated inward, so that the lower ends of the two chucks 5 rotate inward, and the lower ends of the two chucks 5 contact the corresponding slot. The distance between the two chucks 5 is less than the width of the slot, so the slot structure can be easily removed from the carton.

[0026] The rotating sleeve 7 and the corresponding torque rod 8 structure can be adjusted by sliding the slide block 4 on the sliding plug seat 3 to adjust the left and right positions of the two rotating clamps 5 on the outside of the slide block 4, thereby adapting to plug structures with different spacing. At the same time, the torque rod 8 maintains a constant linkage with the rotating sleeve 7, because the two rotating clamps 5 can be retracted by rotating the torque rod 8 that connects to one rotating clamp 5.

[0027] A torsion spring is installed at the junction of the rotating sleeve 7. A spur gear 12 is fixed to the middle circumference of the rotating sleeve 7. A corresponding meshing tooth block 11 is provided on one side of the spur gear 12. The tooth block 11 slides up and down in the plug seat 3, and a limiting block located on the upper side of the plug seat 3 is fixed at the upper end of the tooth block 11. A camshaft 13 is rotatably connected to the lower center of the assembly base 1. The camshaft 13 corresponds to several tooth blocks 11. A motor 14 is fixedly installed on the outside of the assembly base 1. The output shaft of the motor 14 is fixedly connected to the camshaft 13. After inserting an appropriate number of plug seats 3 into the assembly base 1, the left and right positions of the slides 4 on both sides of the plug seat 3 are adjusted. At this time, the insertion head structure is adjusted and the carton insertion operation can be carried out. Insert the insertion head structure into the insertion grid. The two rotary chucks 5, due to the outer sponge pads 6, can easily enter the slots of the insert grid. The sponge pads 6 automatically fill the gaps and unfold inside the slots. Several rotary chucks 5 are inserted into multiple slots of the insert grid, forming a frictional connection with the insert grid. At this time, the insert grid can be loaded into the carton through the insert head. After the insert grid is loaded into the carton, the camshaft 13 connected by the motor 14 rotates. The camshaft 13 presses several upper toothed blocks 11 to move upward. The moving toothed blocks 11 drive the spur gear 12 meshing on one side. Several rotating spur gears 12 drive the rotating sleeve 7 to rotate. Through the torque rods 8 that limit the rotation at both ends, the rotary chuck 5 connected to the outer end of the torque rod 8 rotates, thereby realizing the inward retraction of the rotary chuck 5, and thus making it easy to remove the insert head structure.
