Description

Technical Field

[0001] The utility model relates to the technical field of wire winding equipment, in particular to a 3D printing wire winding device. Background Art

[0002] 3D printing is a technology that uses digital model files as the basis and uses a layer-by-layer printing method to construct objects using bonded materials such as powdered metal or plastic. 3D printing materials include soft materials such as TPU and TPE. After the soft materials are extruded into wire, they need to be wound onto a reel or drum.

[0003] The patent (CN220375974U) discloses a 3D printing wire winding device. It includes a base plate, two mounting plates arranged on the top of the base plate, and a winding roller rotatably arranged between the two mounting plates, and a guide component for guiding the wire is arranged between the two mounting plates. The beneficial effect of the utility model is that since a guide component for guiding the wire is arranged between the two mounting plates, the wire can be guided, avoiding the problem that the winding roller cannot be fully used due to the accumulation of wires, thereby improving the winding rate of the winding roller.

[0004] The 3D printing wire winding device in the above patent document has a winding roller that is rotatably arranged between two mounting plates. When the roll needs to be changed, the mounting plates can only be removed before the roll is changed, which is relatively cumbersome to operate. In addition, the guide ring in the guide assembly will cause contact wear to the 3D printing wire. Although a protective ring is installed in the guide ring, the rubber material of the protective ring is still in friction contact with the 3D printing wire, which will still cause contact wear.
