Description

Technical Field

[0001] The utility model relates to the technical field of 3D printer accessories, in particular to an improved environmentally friendly material roller for a 3D printer. Background Art

[0002] With the maturity of 3D printing technology and the increase in market demand, the requirements for 3D printing related products are becoming more and more stringent. At present, the mainstream materials for home 3D printers are ABS resin and PLA resin. These printing materials are made into linear material strips for use as consumables. The material strip is wound on the material roller for use. The material roller includes a roller for winding the material strip and a concentrically arranged circular baffle. When in use, the material roller is placed in the corresponding material roller groove in the 3D printer, and the outer peripheral edge of the circular baffle contacts the driving roller of the 3D printer. The friction force of the driving roller drives the material roller to roll and feed the material. This material roller is usually made of plastic material, which is both reliable and wear-resistant; however, with the upgrading of environmental protection requirements, this plastic material roller no longer meets environmental protection requirements. Therefore, the utility model patent with the authorization announcement number CN219988490U applied by the applicant discloses an environmentally friendly material roller for 3D printers. The material roller is made of cardboard and coated with a wear-resistant layer, which can meet environmental protection requirements. But on the other hand, this material roller is discarded after being used once, resulting in a waste of resources and increasing the cost of use. Therefore, there is still room for improvement.

Corresponding radial through holes (5a, 5b) are provided at the overlapping part of the first cylinder 2 and the second cylinder 4, and a locking pin 6 is provided to radially pass through the radial through holes (5a, 5b) to fix the first cylinder 2 and the second cylinder 4; Wear-resistant layers 11 are hermetically coated on the outer peripheries of the first circular baffle 1 and the second circular baffle 3; it also includes a third cylinder 7 that can be adaptively sleeved on the outer periphery of the second cylinder 4 for winding wire alone.

[0017] During production, insert the first cylinder 2 into the second cylinder 4 and fix the two with the locking pin 6 to form a complete material roller, and wind the wire on the outer wall of the second cylinder 4; during use, after the material wire is used up, first remove the locking pin 6, then take out the first cylinder 2 from the second cylinder 4, then insert the third cylinder 7 with the wound wire outside the second cylinder 4, and finally insert the first cylinder 2 into the second cylinder 4 to continue using; Therefore, only by replacing the third cylinder 7 for winding wire can it be reused, avoiding waste of resources, reducing the transportation and use costs of products, and being more environmentally friendly. The body of the material roller is made of cardboard, which is environmentally friendly and harmless. The wear-resistant layer 11 is hermetically coated on the outer periphery of the circular baffle, which can not only contact and drive with the driving roller of the 3D printer without wear, but also make the paper circular baffle moisture-proof to avoid softening and damage.

[0018] In a preferred solution, the length of the second cylinder 4 in this embodiment is not less than the length of the first cylinder 2, and the length of the third cylinder 7 is equal to the length of the second cylinder 4. Whether the material wire is wound on the second cylinder 4 or the third cylinder 7, it can avoid the material wire falling into the gap from the end of the cylinder and affecting the continuous wire output during use.

[0019] In a preferred solution, a first through hole 12 with a diameter not greater than the inner diameter of the first cylinder 2 is concentrically opened in the first circular baffle 1 of this embodiment, and the second circular baffle 3 is provided with a second through hole that is concentric with and has the same diameter as the first through hole 12.

After the tape is wound, its tail end passes through the second threading holes (9a, 9b) for fixation. Each group including two second threading holes (9a, 9b) facilitates the knotting and fixation of the tail end of the tape, without the need to wind it around the outer peripheral edge of the circular baffle, which may affect the rotation of the material roll.

[0022] In a preferred embodiment, a radial viewing window groove 10 is provided on the first circular baffle 1 and / or the second circular baffle 3 of this embodiment. The radial viewing window groove 10 facilitates observing the remaining amount of the tape.
