Description

3D prints the screw rod propulsive mechanism of board pen ink

Technical field

The utility model relates to a kind of 3D printing technique, and especially a kind of ink printing pen advances structure, and specifically a kind of 3D prints the screw rod propulsive mechanism of board pen ink.

Background technology

3D prints pen, is utilize rapid shaping technique by controllable device, and the speed flowed out by control resin, draws the product printing and needing.

Application number be 201310266463.8 patent of invention disclose a kind of 3D and print pen, this patent document 3D prints a complicated integral structure, and volume is big. 3D common in existing market prints handwriting and amasss bigger than normal, and ink pipe store content is few, and electric machine control system takies and prints an inner most space. For domestic and international children population, on market, existing 3D prints a poor controllability, not yet grows up due to children population hand shape and control deficiency, landing when pen uses occurs to print often, breaks, and it is low that 3D prints a work-ing life. These are all the problems always perplexing the heads of a family.

Consider 3D print pen can Portability and controllability, 3D print pen advance structure improvement, adopt screw rod advance structure, simplify control electric system, can directly reduce print an internal space, reduce print handwriting amass, easy to carry.

Practical novel content

The purpose of this utility model prints handwriting for existing 3D to amass big problem, designs the screw rod propulsive mechanism that a kind of 3D prints board pen ink, and it optimizes 3D and prints an internal structure, reduces 3D and prints an overall volume, can improve portability and controllability.

The technical solution of the utility model is:

A kind of 3D prints the screw rod propulsive mechanism of board pen ink, it is characterized in that it comprises motor base 1, screw rod base 3, piston 4, screw rod 5 and screw rod support pad 6, motor base 1 is fixed on and prints on a plastic casing, motor output shaft is connected through ink pipe bonnet 2 with screw rod base 3, ink pipe bonnet 2 spinning is on ink pipe shell 7, one end of screw rod 5 is connected with screw rod base 3, the other end is bearing in screw rod and supports on pad 6, piston 4 spinning is on screw rod 5, the periphery of piston 4 is provided with direction recess or projection, projection on described direction recess or protruding and black pipe shell 7 inwall or groove 8 phase is mated to prevent the rotation of piston 4.

Described motor is direct-current machine, and motor base 1 output shaft is polygonal body.

Described screw rod base 3 is the polygonal hole corresponding with motor base 1 output shaft body.

Described screw rod supports shape on pad 6 to be had for the axially extending bore that ink passes through.

Projection or groove 8 on described ink pipe shell 7 inwall are embedded in ink pipe shell 7.

The beneficial effects of the utility model:

The screw rod that the utility model 3D prints pen advances structure to be applied on 3D printing pen, utilizes screw rod to advance structure, and without push-rod electric machine, control is simple, simplifies electric machine control system, reduces a printing internal space, can improve ink pipe capacity. Screw rod of the present utility model advances structure and existing 3D to print pen and advances compared with structure, effectively solve in children population use procedure, not easily control, the problem that 3D prints the outer landing of meaning of a passage, breaks, simple operation, can Portability, the property controlled is strong.

Accompanying drawing explanation

Fig. 1 is that solid of the present utility model decomposes structural representation.

In figure: 1 is motor base, 2, and be that after ink pipe, shell, 3 be screw rod base (Polygons pilot hole), 4 is piston, 5 to be screw rod, 6 be that screw rod supports pad, 7 be ink pipe shell, 8 is the projection in ink pipe shell or groove.

Embodiment

Below in conjunction with drawings and Examples, the utility model is further described.

As described in Figure 1.

A kind of 3D prints the screw rod propulsive mechanism of board pen ink, it comprises motor base 1, screw rod base 3, piston 4, screw rod 5 and screw rod support pad 6, motor base 1 is fixed on and prints on a plastic casing, polygonal body motor output shaft inserts in the polygonal hole of screw rod base 3 through ink pipe bonnet 2 and drives screw rod base 3 to rotate, ink pipe bonnet 2 spinning is on ink pipe shell 7, one end of screw rod 5 is connected with screw rod base 3, the other end is bearing in and supports on pad 6 with the screw rod of the axially extending bore passed through for ink, piston 4 spinning is on screw rod 5, the periphery of piston 4 is provided with direction recess or projection, projection on described direction recess or protruding and black pipe shell 7 inwall or groove 8 phase is mated to prevent the rotation of piston 4. described projection or groove 8 are by inlaying or integrated injection molding is shaped and is able to.

The utility model utilizes screw rod 5 to advance, and motor 1 adopts without push-rod electric machine, after motor 1 is energized, motor base 1 output shaft drives screw rod 5 to rotate, piston 4 is straight forward movement under direction recess or convex role, promotes ink inner resin tube to flow out smoothly from nozzle, draws the product of printing demand.

The utility model does not relate to part and all same as the prior art prior art maybe can be adopted to be realized.
