Abstract

The utility model discloses a 3D print pen's pay -off structure, include the pen container and install in the inside feeding mechanism in its upper end, feeding mechanism includes motor, gear box and pay -off gear, feeding mechanism vertically install in pen container upper end, it still includes worm gear mechanism, worm gear mechanism with gear box, the equal transmission of pay -off gear are connected. Originally, be arranged in 3D print pen's pay -off structure, feeding mechanism vertically places, promptly with pen container parallel arrangement, because it is assembled the width and is less than 13mm usually, further makes 3D print pen's overall diameter be less than 15mm, strengthens 3D print pen's dexterity nature and convenience greatly.

Description

A kind of 3D prints the feeding structure of pen

Technical field

The utility model relates to 3D printing technique, specifically refers to that a kind of 3D prints the feeding structure of pen.

Background technology

3D prints (3DPrinting), the i.e. one of rapid shaping technique, is that a kind of powdery metal or plastics etc. of using can jointing material, carrys out the technology of constructing stereo object.Along with the development of 3D technology, 3D printing pen technology have also been obtained and develops fast, and 3D prints the three-dimensional real object figure that pen can draw 3D, such as can print straight connecing with 3D and draw three-dimensional ring, wrist-watch, car, house etc.

And existing 3D prints pen, generally structurally there is following shortcoming: 1, all structures are installed in casing, make whole printing pen too thick, to hold and uncomfortable, if the little adult of hand or children use time, can be painstaking especially; 2, use underaction, the range of choice of consumptive material is narrower.Therefore, how making 3D print pen thickness the same as common pen, dexterousr convenience during use, is those skilled in the art's problems in the urgent need to address.

Summary of the invention

In order to overcome above-mentioned deficiency of the prior art, the utility model provides the feeding structure that a kind of 3D prints pen, this reasonable in design, 3D printing handwriting can be made to amass become small and exquisite, use also convenient by it.

The utility model solves the technical scheme that its technical problem adopts:

A kind of 3D prints the feeding structure of pen, comprise pen container and be mounted thereon the inner feed mechanism of end, described feed mechanism comprises motor, gear-box and feeding gear, described feed mechanism is longitudinally installed on described pen container upper end, it also comprises worm-and-wheel gear, and described worm-and-wheel gear and described gear-box, feeding gear are all in transmission connection.

As the improvement of technique scheme, described worm-and-wheel gear is installed on directly over described gear-box, and is arranged at same level with described feeding gear, forms a perpendicular type drive mechanism thus.

As the improvement of technique scheme, described pen container offers the feeding mouth for charging.

As the improvement of technique scheme, described feeding mouth is opened in the pen container upper wall directly over described feeding gear or is positioned at the pen container sidewall of same level with described feeding gear.

The beneficial effect that the utility model brings has:

This is used for 3D and prints in the feeding structure of pen, and feed mechanism is longitudinal placement, namely be arranged in parallel with pen container, and because its overall width is less than 13mm usually, the overall diameter making 3D print pen is further less than 15mm, greatly strengthens dexterity and convenience that 3D prints pen.

Accompanying drawing explanation

Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail,

Accompanying drawing 1 is feeding structure schematic diagram of the present utility model;

Accompanying drawing 2 is feeding structure schematic diagrames that existing 3D prints pen.

Detailed description of the invention

The utility model discloses a kind of feeding structure printing pen for 3D, this structure mainly comprises pen container and is installed on the feed mechanism of inside, pen container upper end, in use, feeding mouth from feed mechanism enters by printing consumables, and after the inner thermoplastic of pen container, realize 3D by ejection in the nozzle discharge hole of pen container front end and print.

Concrete, feed mechanism comprises motor 1, gear-box 2 and feeding gear 3, and with reference to accompanying drawing 2, existing 3D prints pen, and its feed mechanism is horizontally installed in pen container mostly, and this makes 3D print the diameter of pen usually much larger than 30mm, and holding and using all has inconvenience.For this reason, the utility model improves the mounting means of above-mentioned feeding structure targetedly, with reference to accompanying drawing 1, in the present embodiment, feed mechanism is longitudinally installed on the upper end of pen container, namely be arranged in parallel with pen container, simultaneously except comprising above-mentioned necessary drive mechanism, it also comprises worm-and-wheel gear 4, by worm-and-wheel gear 4, reaches the charging effect with existing structure equivalence.

Further, worm-and-wheel gear 4 is specifically arranged on directly over gear-box 2, and is arranged at same level with feeding gear 3, and meanwhile, worm-and-wheel gear 4 and gear-box 2, feeding gear 3 are all in transmission connection, and what form a perpendicular type thus turns to drive mechanism.Under the prerequisite ensureing same charging effect, again because above-mentioned its overall width of feed mechanism longitudinally arranged is less than 13mm usually, the overall diameter making 3D print pen is less than 15mm, thus greatly strengthens dexterity and convenience that 3D prints pen.

In addition, pen container should be offered the feeding mouth for charging, feeding mouth can be opened in pen container top upper wall, also can be opened in the pen container sidewall being positioned at same level with feeding gear 3.

It should be noted that, the above is preferred embodiment of the present utility model, and the utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection domain of the present utility model.
