[0043] See also Figure 1-7 The utility model provides a technical solution: an anti-knotting 3D printing consumables packaging box, comprising a packaging box 1, a consumables tray 2 and a roller mechanism 3.

[0044] The packaging box 1 comprises a box body 11, two sets of side flaps 12 and a main flap 13. The two sets of side flaps 12 are integrally turned and connected to the two side edges of the top of the box body 11, and the main flap 13 is integrally turned and connected to the rear end edge of the top of the box body 11. Specifically, the packaging box adopts a foldable box cover design, which can completely cover the box body 11 to form a relatively sealed space, which can reduce the direct contact between the consumables and the air and avoid problems such as moisture absorption or oxidation of the consumables.

[0045] The inner wall of the box body 11 is provided with a moisture-proof coating 113. Specifically, the moisture-proof coating 113 can be a composite coating composed of polymer materials such as polystyrene, polyvinyl alcohol, and polyvinyl acetate and inorganic materials such as nano-aluminum oxide and nano-zinc oxide, which can form a uniform, dense, and transparent moisture-proof film on the inner wall of the box body 11, effectively isolating the penetration of moisture and air, thereby protecting the 3D printing consumables from problems such as moisture and oxidation, extending their service life and maintaining their printing effect.

[0046] The front and rear sides of the box body 11 are both provided with mounting holes 111 , and the upper end of the box body 11 close to the side flip cover 12 is provided with a discharge port 112 .

[0047] The consumable tray 2 is connected to the inner side of the box body 11 . A center ring 21 is integrally provided on the inner side of the consumable tray 2 . A plurality of brackets 22 are fixedly connected between the center ring 21 and the inner wall of the consumable tray 2 .

[0048] The roller mechanism 3 is arranged on the box body 11, and the roller mechanism 3 comprises an inner cylinder 31 and two sets of outer cylinders 32, wherein:

[0049] The inner cylinder 31 is connected to the inner side of the center ring 21;

[0050] The two groups of outer cylinders 32 are respectively connected to the two groups of mounting holes 111 , and the two groups of outer cylinders 32 are respectively connected to the two ends of the inner cylinder 31 .

[0051] Specifically, the inner diameter of the center ring 21 is greater than the outer diameter of the inner cylinder 31 , and the consumable tray 2 can be rotated outside the inner cylinder 31 through the center ring 21 .

[0052] The outer sides of both ends of the inner cylinder 31 are integrally connected with limiting rings 313, and the outer diameter length of the limiting rings 313 is greater than the inner diameter length of the mounting hole 111, and the outer diameter length of the inner cylinder 31 is adapted to the mounting hole 111. Specifically, the edges of both ends of the inner cylinder 31 are respectively connected to the two groups of mounting holes 111, and the limiting rings 313 have a limiting effect on the inner cylinder 31, which can prevent the inner cylinder 31 from detaching from the inner side of the box body 11, thereby preventing the roller mechanism 3 from falling off or shifting, and ensuring its stability and safety.

[0053] The outer cylinder 32 includes an external portion 321 and an inserting portion 322, wherein:

[0054] The external part 321 is integrally connected with the plug-in part 322, and the surface of the external part 321 is integrally connected with a plurality of groups of anti-slip protrusions 3211 in a regular annular array;

[0055] Two groups of clamping blocks 3221 are integrally connected to the surface of the plug-in portion 322 .

[0056] Specifically, the outer diameter of the external part 321 is greater than the inner diameter of the mounting hole 111. The external part 321 is located on the outside of the box body 11. By providing an anti-slip protrusion 3211 on the surface of the external part 321, the friction force when the user holds the roller mechanism 3 can be increased, thereby improving practicality.

[0057] The outer diameter length of the plug-in portion 322 is matched with the inner diameter length of the inner cylinder 31. Specifically, this can ensure the connection tightness and smoothness of the roller mechanism 3, and realize the quick assembly of the outer cylinder 32 and the inner cylinder 31 through the plug-in portion 322.

The block 3221 is connected to the first slot 311 by plugging, and the block 3221 is connected to the second slot 312 by rotation. Specifically, when the outer cylinder 32 is connected to one end of the inner cylinder 31, the plug-in portion 322 is inserted into the inner side of the inner cylinder 31. In this process, the two groups of blocks 3221 are respectively connected to the two groups of first slots 311. Then, the outer cylinder 32 can be rotated so that the two groups of blocks 3221 are respectively connected to the two groups of second slots 312. In this way, the roller mechanism 3 can be quickly installed and disassembled, and the locking and adjustability of the roller mechanism 3 are also increased.

[0059] Specifically, referring to instructions 6-7, the first slot 311 is connected to the outside of the inner cylinder 31, the second slot 312 is arranged close to the first slot 311, and the inner cylinder 31 is made of a deformable material. In this way, when the outer cylinder 32 and the block 3221 are rotated, the block 3221 can cause appropriate deformation to the connection between the second slot 312 and the first slot 311, so that the block 3221 is embedded in the second slot 312, thereby realizing a locked connection between the outer cylinder 32 and the inner cylinder 31.

[0060] The consumables are installed on the consumable tray 2, and the ends of the consumables are inserted and connected in the discharge port 112, and the ends of the consumables extend from the inside of the box body 11 to the outside of the box body 11 through the discharge port 112. Specifically, the consumables have a certain friction when passing through the discharge port 112, and the consumables are not easy to fall through the discharge port 112, and the user can use it all the time, thereby avoiding the problem of tangling caused by human factors.

[0061] Specifically, when in use, the center ring 21 is sleeved on the outer middle part of the inner cylinder 31 to realize the connection between the roller mechanism 3 and the consumable tray 2. The two ends of the inner cylinder 31 are respectively connected to the two groups of mounting holes 111, and the two groups of outer cylinders 32 are connected to the front and rear walls of the box body 11, and the two groups of outer cylinders 32 are respectively inserted into the two ends of the inner cylinder 31. The user only needs to take out the consumables of the required length from the discharge port 112 on the side of the box body 11 and fix the end at the discharge port 112. When the user needs to replace or retrieve the consumables, he only needs to gently rotate the consumable tray 2 to wind the consumables on the consumable tray or release them from the consumable tray. This can effectively prevent the consumables from sliding or winding in the box body 11 and causing knotting.
