From principle, 3D printing device volume and the 3D of each 3D printing technique, be printed as originally, the equipment that adopts FDM fusion stacking forming technique for individual consumer is that holistic cost is minimum and take up room minimumly, so we can see that the 3D printer of selling towards ordinary consumer is on the market all based on FDM fusion stacking forming technique.
The 3D printer of FDM principle comprises 3 axis motion systems, heating system, levelling control system, cooling control system, advance and retreat material control system, panel operation system, power supply voltage-stabilizing system and motor driven systems.
3 described axis motion systems mainly comprise: stepper motor, optical axis, belt, axle sleeve, bearing, structural member, belt pulley, leading screw, nut, screw are some.
Implementation procedure:
Stepper motor drives belt rotation, and bindiny mechanism is stuck on belt, and this has just formed the motion of a direction, and the effect of optical axis has two kinds: 1 is mainly guide effect as optical axis; 2 are mainly transferring power effect as optical axis, and leading screw is connected with motor, is furnished with nut on leading screw, and when making, nut is connected with working face.Stepper motor drives by controlling accordingly drive plate, has so just formed X/Y/Z three-axis moving.
Type from existing market can find out, the range of application of FDM technology is mainly aspect small plastic forming parts at present, and the main problem existing has:
1, the leveling of working panel is artificial leveling, and not only trouble but also error are large, and the ratio of briquetting of model is had to very large impact;
2, FDM technology exists model inhomogeneous cooling even and alice occurs, and causes FDM technology cannot print large-scale part;
3, FDM printer in the market all adopts the feeding manner of side bridging, this mode makes material form with curve under feeding mechanism drives enter shower nozzle, and cause charging resistance to strengthen, be with motionless charging tray rotation, the phenomenons such as difficult feed, process to printer model has a strong impact on, and can damage machine;
4, the 3D printer of FDM class lacks the monitoring device of shower nozzle putty at present, and causes personnel can not find in time failure of printer model, thereby waste is a large amount of, prints the alignment time.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of 3D printer with suspension and the process display system of automatic horizontal control system, cooling control system, material.
The utility model is to realize like this, a kind of 3D printer of large-scale FDM principle, comprise 3 axis motion systems, heating system, levelling control system, cooling control system, advance and retreat material control system, survey material control system, panel operation system, power supply voltage-stabilizing system and motor driven systems, also include suspension and the process display system of material, described levelling control system comprises distance measuring sensor, working panel, base, motor and spring, distance measuring sensor is arranged on the top of working panel, working panel is connected with motor, on motor shaft, be provided with spring, described cooling control system has also adopted fan, the suspension of described material comprises material support, prop up material rod, material volume, wire rod plastics, described process display system comprises LCD display, and the circuit of corresponding LCD.
Present technique has solved most of technical barrier of FDM, and for FDM technology, print large parts possibility is provided, the leveling mode of present technique working panel changes automatic leveling into, utilize distance measuring sensor to reduce range error, add large area cooling fan and solved FDM bridge limit problem, changed the hang of material, improved the charging problem that has some setbacks, and utilize monitoring device to monitor print procedure, for operating personnel provide monitoring platform, effectively shortened the required time of printer model.
Accompanying drawing explanation
Fig. 1: levelling control system structure chart;
Fig. 2: cooling control system schematic diagram;
Fig. 3: the suspension schematic diagram of material.
Wherein, 1, distance measuring sensor 2, working panel 3, thread spindle motor 4, base 5, spring 6, large area fan 7, print module 8, material 9, a material rod 10, material volume 11, wire rod plastics.
The specific embodiment
As Fig. 1, described levelling control system mainly comprises distance measuring sensor and thread spindle motor, distance measuring sensor (1) is arranged on the top of working panel (2), can implement the position of monitoring panel, working panel is connected with three thread spindle motors (3), on thread spindle, be provided with spring (5), three thread spindle motors are fixedly connected with by base (4).
Distance measuring sensor and triaxial movement platform are fixed together, and according to 3 principles of determining planes, by the test point of plank, with triangular arranged, find range in three summits that then distance measuring sensor moves to respectively equilateral triangle.Start after leveling program, CPU is to distance measuring sensor work order, distance measuring sensor starts range finding, then feed back range data to CPU, CPU contrasts the range data of feedback and predeterminable range data, if the range data of feedback is larger than predeterminable range data, CPU startup thread spindle motor is rotated in the forward, because the thread spindle of motor is connected with whorl of base, and electric machine casing is because the restriction of base does not allow rotation, when motor shaft is rotated in the forward, motor rises, working panel rises, reduce the distance, distance measuring sensor continues range finding, until reach predeterminable range.If the range data of feedback is less than predeterminable range, the reverse rotation of measured motor axle, motor declines, and working panel declines, and increases distance, until reach predeterminable range.
Cooling control system mainly comprises cold solid to motor, shower nozzle and material, current FDM technology can not be printed large-sized model, there is direct relation with the inhomogeneous cold solid bridge limit problem causing of material, in order to guarantee the effective moulding of large scale FDM parts, we adopt directly cooling printer model in print procedure of large area cooling fan, thereby reduce the internal stress of material, reduce part alice probability.
As Fig. 2, large area fan (6) printer model (7), shown in large area fan printer model is carried out cooling in time in print procedure, air-flow is taken away amount of heat, accelerate model cooling velocity, and evenly cooling to the model of having accomplished fluently, fall low heat conductivity, realization beats cooling.
The suspension of material: as Fig. 3, the suspension of material mainly comprises material (8), a material rod (9), material volume (10) and wire rod plastics (11), during charging due to the engagement of feeding mechanism, material is engaged to advance, thereby drive material to twist in the upper rotation of a material rod (9), this hang has guaranteed that material directly enters feeding mechanism, has avoided material to enter feeding mechanism with other curve modes, greatly reduce charging resistance, improved charging reliability.
Process display system: process display system mainly comprises the circuit of LCD display and corresponding LCD, can show the process of printing, nozzle temperature timely, makes operating personnel can get information about speed and time-write interval that model is printed.
