Problems solved by technology

[0002] The consumable feeding device is an important part of the fused deposition 3D printer. The current mainstream consumable feeding device generally presses the wire feeding gear on the consumable, and then sends the wire to the nozzle through the gear driven by the motor. The advantage of this method is that the structure of the printer is simple, and it has high reliability when used within a reasonable range of working conditions; the disadvantage is that only one filament can be clamped at a time. Depending on the type of consumables, the consumables must be replaced manually, which may even lead to interruption of printing, which is not suitable for the needs of automated production
On this basis, there is a way to realize the conversion feeding of multi-coil filaments by increasing the number of consumable feeding devices, but it causes the defects of complex mechanical structure, increased volume, and increased cost of the printer, and this method of refueling affects the printed parts. The surface quality is not conducive to actual production and use

Embodiment Construction

[0014] Such as figure 1 As shown, the automatic continuation and replacement device for fused deposition 3D printer consumables includes a mobile worktable 1, a storage room 2 and a cutting device. The storage room 2 is arranged on the mobile workbench 1, and multiple vertical The feeding pipe 4 that is set straightly, the upper end of the feeding pipe 4 is provided with a self-locking mechanism; the cutting device is located at the top of the storage chamber 2, and the cutting device includes a cutter 5, a feeding mechanism and an unlocking mechanism corresponding to the self-locking mechanism.

[0015] The self-locking mechanism consists of reeds 6 that are arranged on the inner wall of the feed pipe 4 and are evenly distributed along the circumference of the feed pipe 4. The upper end of the reed 6 is fixedly connected with the feed pipe 4, and the lower end of the reed 6 faces the feed pipe. 4 Medial slope.

[0016] The unlocking mechanism includes an annular snap ring 7,...

Abstract

An automatic consumable replenishing and replacing device for a fused deposition 3D printer comprises a movable workbench, a storage chamber and a cut-off device. The storage chamber is arranged on the movable workbench. A plurality of vertically-arranged feeding pipes are arranged in the storage chamber. A self-locking mechanism is arranged at the upper end of each feeding pipe. The cut-off device is arranged above the storage chamber and comprises cutters, a feeding mechanism, and an unlocking mechanism corresponding to the self-locking mechanisms.

Description

technical field [0001] The invention relates to 3D printing equipment, in particular to an automatic splicing and replacing device for fused deposition 3D printer consumables. Background technique [0002] The consumable feeding device is an important part of the fused deposition 3D printer. The current mainstream consumable feeding device generally presses the wire feeding gear on the consumable, and then sends the wire to the nozzle through the gear driven by the motor. The advantage of this method is that the structure of the printer is simple, and it has high reliability when used within a reasonable range of working conditions; the disadvantage is that only one filament can be clamped at a time. When different types of consumables are used, the consumables must be replaced manually, which may even lead to interruption of printing, which is not suitable for the needs of automated production. On this basis, there is a way to realize the conversion feeding of multi-coil f...
