Abstract
The utility model discloses a 3D prints and prevents wire drawing device, including support piece, steering wheel and separation piece, support piece's one end links to each other with the steering wheel is fixed, and the other end links to each other with the nozzle of 3D printer is fixed, the nozzle can keep perpendicular downward down or to side rotation angle A in steering wheel effect, steering wheel and separation piece are fixed respectively on the support of 3D printer relevant position, the fixed back of separation piece is A with the contained angle that the horizontal plane becomes, the nozzle is just laminated with the separation piece is perpendicular during to side rotation angle A. This technical scheme has following effect: 1, through the mode that the separation piece blocks the nozzle, fundamentally solves the wire drawing problem, than pumpback mode more thoroughly commonly used at present. 2, the nozzle can keep the clean and tidy of nozzle surface through the separation of separation piece to reduce waste material interference model finish.
Description
Technical field
The utility model relates to a kind of accessory field of 3D printer, particularly relates to a kind of device that can prevent the wire drawing of 3D printer.
Background technology
It is novel forming technique that 3D prints, and the structure of 3D printer of the prior art is generally all divided into two-layer up and down, and upper strata is printhead and XY drive mechanism, and lower floor is article carrying platform.Its XY drive mechanism at the middle and upper levels comprises the printhead that the plane that can be formed in X-axis and Y-axis can carry out movement, and lower floor is provided with article carrying platform.The article carrying platform of 3D printer of the prior art can rise along Z-direction or decline, thus presses layer printing 3D workpiece.When printing, filler accumulation type printing technique utilizes the printhead of heating to merge filler, by controlling printhead, the filler of molten is stacked on assigned address, thus 3D model conversation is become the 3D workpiece of entity.3D printer is in print procedure, for irregular object, printhead often needs to move fast and shift one's position, before printhead moves, 3D printer needs the supply stopping silk material, in the process that print head position moves and converts, what least wish to see is exactly that the silk material of melting is extruded from nozzle, but due to the impact of silk material self gravitation, be difficult to ensure that printhead can stop extruding of silk material instantaneously, this unnecessary silk material squeeze-out phenomenon is referred to as wire drawing phenomenon in the art.This phenomenon can reduce precision and the surface smoothness of printing objects, affects the U.S. shape of printing objects, also easily causes the waste of silk material in addition.
Utility model content
In order to solve the defect that prior art exists, when the utility model provides a kind of 3D to print, prevent the wire drawing of nozzle place from affecting the device of printer model.
To achieve these goals, the technical solution adopted in the utility model is: a kind of 3D prints anti-wire-drawing frame, comprises support member, steering wheel and barrier flaps; One end and the steering wheel of described support member are fixedly linked, and the nozzle of the other end and 3D printer is fixedly linked; Described nozzle can keep vertically downward or to side flip angle A under steering wheel effect; Described steering wheel and barrier flaps are separately fixed on the support of 3D printer relevant position; It is A that described barrier flaps fixes angle formed by rear and horizontal plane; Described nozzle is fitted to just vertical with barrier flaps during side flip angle A.
After adopting the technical solution of the utility model, in the process of nozzle movement, nozzle can be fitted, after laminating to side flip angle is vertical with barrier flaps by steering wheel, the outlet of nozzle can be blocked completely, the wire drawing problem caused extruded by the silk material solving melting from nozzle.The technical program has following effect: 1, by the mode of barrier flaps stopped nozzles, fundamentally solves wire drawing problem.More thorough than pumpback mode conventional at present.2, nozzle is by the obstruct of barrier flaps, can keep the clean and tidy of nozzle surface, thus reduces waste material interference model surface smoothness.
Further improvement, described support member is be greater than the L shaped plate of 90 degree.The design of L shaped plate can ensure that nozzle can be fixed by support member securely.
Further improvement, the shape of described barrier flaps is circular arc.The shape of barrier flaps is that circular arc can the upset scope of enlarged nozzle, makes nozzle can obtain protected effect better by suitable adjustment.
Accompanying drawing explanation
Fig. 1 be 3D print anti-wire-drawing frame nozzle vertically downward time structural representation.
Fig. 2 is that 3D prints the nozzle of anti-wire-drawing frame to structural representation during side flip angle A.
Detailed description of the invention
The scheme preferential to the utility model below in conjunction with accompanying drawing is further elaborated:
As depicted in figs. 1 and 2, a kind of 3D prints anti-wire-drawing frame, comprises support member 2, steering wheel 1 and barrier flaps 3.One end and the steering wheel 1 of described support member 2 are fixedly linked, and the nozzle of the other end and 3D printer is fixedly linked by a grip block 4; Certainly realizing that nozzle is fixing can also by alternate manner mode, as long as can by nozzle fixation.In order to ensure that support member 2 can by nozzle fixation and the holding capacity strengthening support member, support member 2 is designed to the L shaped plate that angle is greater than 90 degree.In the process that reality uses, nozzle can realize keeping vertically downward or to side flip angle A under steering wheel 1 acts on.Steering wheel 1 and barrier flaps 3 are separately fixed on the support of 3D printer relevant position; It is A that described barrier flaps 3 fixes angle formed by rear and horizontal plane; The shape of described barrier flaps 3 is circular arc.Described nozzle is fitted to just vertical with barrier flaps 3 during side flip angle A.
Claims (3)
1. 3D prints an anti-wire-drawing frame, it is characterized in that: comprise support member, steering wheel and barrier flaps; One end and the steering wheel of described support member are fixedly linked, and the nozzle of the other end and 3D printer is fixedly linked; Described nozzle can keep vertically downward or to side flip angle A under steering wheel effect; Described steering wheel and barrier flaps are separately fixed on the support of 3D printer relevant position; It is A that described barrier flaps fixes angle formed by rear and horizontal plane; Described nozzle is fitted to just vertical with barrier flaps during side flip angle A.
2. 3D according to claim 1 prints anti-wire-drawing frame, it is characterized in that: described support member is be greater than the L shaped plate of 90 degree.
