3D printing flexible wire winding device and working method thereof

Abstract

The invention discloses a 3D printing flexible wire winding device and a working method thereof. A lifting device and a plurality of wire storage devices are arranged, and thus, the single wire storage device can be conveniently replaced with another wire storage device after one completes winding; a fixing mechanism, a cutting device and a thickness measuring module are arranged, so that the thicknesses of the wires on a reel are measured, and the wires between a wire inlet device and the reel are automatically cut off when the thicknesses reach a threshold value; the wires can be fixed on another reel by a lifting device and the fixing device, so that automatic switching of the reels when winding is achieved; and the position of the reels on the lifting device can be detected by a position measuring module, and the positions of the reels on the lifting device are adjusted in real time according to the thickness of the wires on the reels, so that the distance between the wire inlet device and the reels is kept unchanged, and the problem that, due to thickness change of the wires on the reels, the tension of the wires when winding is changed to cause stretching deformation of the wires and ultimately influence on the quality of the flexible wires is avoided.

Description

technical field [0001] The invention relates to the technical field of 3D printing material production, in particular to a 3D printing flexible wire winding device and its working method. Background technique [0002] 3D printing materials include TPU, TPE and other soft materials. After the soft materials are extruded, the motor needs to drive the wire reel to wind up. When winding up, a certain tension must be maintained, but if the tension is too high, the wire will be easily pulled. Stretch deformation, resulting in smaller size of the wire, especially when the wire on the storage rack gradually increases, the diameter of the winding wire increases, and the distance between the outer wire of the storage rack and the extruder is shortened. The fixed speed and tension are used to wind the wire, and the soft wire will be deformed during the stretching process. Although a tension control system is provided in the prior art, when the wire reel is replaced during the winding p...

[0002] 3D printing materials include TPU, TPE and other soft materials. After the soft materials are extruded, the motor needs to drive the wire reel to wind up. When winding up, a certain tension must be maintained, but if the tension is too high, the wire will be easily pulled. Stretch deformation, resulting in smaller size of the wire, especially when the wire on the storage rack gradually increases, the diameter of the winding wire increases, and the distance between the outer wire of the storage rack and the extruder is shortened. The fixed speed and tension are used to wind the wire, and the soft wire will be deformed during the stretching process. Although a tension control system is provided in the prior art, when the wire reel is replaced during the winding process, the tension control system It is difficult to accurately and quickly respond to sudden changes in tension caused by changing the reel
