Wire winding device for 3D printer

Abstract

The invention belongs to the technical field of 3D printing wire winding equipment, and particularly relates to a wire winding device for a 3D printer. The wire winding device comprises a base, a first adjusting assembly, a second adjusting assembly, a wire arrangement assembly, a wire storage disc, a first supporting frame, a first motor, a second motor and a first rotating roller; the wire storage disc is in transmission connection with one end of an output shaft of the first motor; a first guide groove is formed in the first rotating roller, the first guide groove is divided into a downhill section and an uphill section, the downhill section and the uphill section are symmetrically arranged, and the two ends of the downhill section and the two ends of the uphill section communicate separately; the wire arrangement assembly comprises a sliding assembly, and one end of the sliding assembly is movably clamped in the first guide groove; and the other end of the sliding assembly is located on the side, away from the first adjusting assembly, of the second adjusting assembly. When the winding diameter of a wire storage shaft is increased, the rotating speed of the second motor can be reduced in real time, so that a wound wire is arranged tidily and compactly.

Description

technical field [0001] The invention belongs to the technical field of 3D printing wire winding equipment, and in particular relates to a wire winding device for a 3D printer. Background technique [0002] 3D printing materials include soft materials such as TPU and TPE. After the soft materials are extruded, they need to be wound up through a motor to drive the wire reel, and a certain tension needs to be maintained during winding. However, if the tension is too high, it is easy to cause the wire to be stretched and deformed, resulting in a smaller size of the wire. Especially when the wire rod on the wire storage rack gradually increases, the diameter of the wire rod when winding increases, and the distance between the outer layer wire rod of the wire storage rack and the extruder is shortened. If the wire is wound up at a constant speed and tension, the soft material deforms during stretching. [0003] In addition, the wire rods rewound by the existing wire rod rewindin...

Problems solved by technology

[0003] In addition, the existing wire rewinding device rewinds the wires messily and not closely, which wastes the wire storage space of the wire storage rack, leading to an increase in production costs.
