Description

3D printing filament precision winding machine

technical field

The utility model relates to the technical field of winding machine design, in particular to a precision winding machine for 3D printing consumables.

Background technique

Due to the high precision requirements of the cross-sectional circle of the 3D printing consumable rubber strip (commonly ∮3 and ∮1.75), the raw materials are complex (such as ABS is hard, PLA is relatively tough, etc.), and the take-up reels are not uniform, so It will also be very troublesome to wind up.

The main manifestation of the current technology is that the wiring is not neat. The current conventional practice is to take up the wires according to the way the wires and cables are rolled up, but the effect is not as neat as the wires and cables. The main reason is that the printing tape is not as flexible as wires and cables; and the wires of the printing tape are relatively thin, even if one of the wires is wrongly picked up, the whole board will be messed up; The baffles on both sides of the disk are relatively soft. During the winding process, the 3D rubber strip will have a force to squeeze to both sides. This will lead to inaccurate wiring and uneven wiring. At present, the main technical difficulty is that it needs to be suitable for winding reels of various specifications while arranging the wires neatly. Some neatly arranged 3D printing tapes have appeared on the market, but the winding method is manual secondary winding, which not only increases labor costs, but also increases time costs.
