The existing 3D printer equipment kind of drive is broadly divided into three kinds: XYZ type, CoreXY type and trigonometric expression parallel arm knot
Structure.The transmission of three axis of the characteristics of XYZ type 3D printer is independent mutually, and three axis are respectively by three stepper motor independent controls；
CoreXY structure uses XY linkage structure, and XY axis is all that two stepper motor cooperations are driven；And trigonometric expression parallel arm
Structure controls the mechanical structure of movement of the target in X, Y, Z axis by a series of parallelogram of interconnections.
Above-mentioned 3D printer is all made of frame-type design, and print head scope of activities is limited in the frame of 3D printer,
Therefore the item sizes of printing are limited in 3d printer frame；To print biggish article, then biggish printer is needed
Bigger placement space.The 3D printer occupied space that existing technical solution can not solve printing large item always is big,
Problem at high cost.
Summary of the invention
For big, the at high cost problem of the 3D printer occupied space of printing large item, the present invention proposes a kind of suspension
Formula 3D printer transmission mechanism.
Suspension type 3D printer transmission mechanism of the invention, the mechanism include center rack, it is characterised in that:
There are three vertically disposed stepper motor and a horizontally disposed stepper motors for setting in the rack of center, vertical to walk
Motor shaft length into motor differs, and motor gear is arranged at the top of motor shaft, and the motor shaft of horizontal step motor is set as worm screw；
Each motor gear is engaged with superposed three transmission gears respectively, worm screw and a transmission for being located at bottom
Turbine engagement, transmission gear and transmission turbine side are fixed with drum, are wound with suspension line on drum；The transmission gear,
It is driven turbine and drum shares a bearing；Six horizontal direction fixed blocks are arranged in the center rack outer rim, and horizontal direction is fixed
Block top sets through-hole, horizontal direction fixed block side two-by-two, and the suspension line in superposed any drum passes through ipsilateral two water
It puts down to fixed block, suspension line two ends are each attached on drum, and the suspension line of closure is extended out to side wall, is suspended on side wall
Hook or fixed pulley on；The center rack outer rim is also evenly arranged there are three vertically to fixed block, vertically to fixed block
Upper setting through-hole, bottom drum is interior to be arranged three suspension lines, and three one ends of suspension line are fixed on the drum of bottom, and suspension line is worn
It crosses vertically to fixed block, the other end is fixed on vertically on fixed block, is passed through and is vertically upwardly extended to the suspension line of fixed block
To top surface, it is suspended on the hook or fixed pulley of top surface.
More specifically, through there is printing material conveying pipeline in the bearing, center bottom of the frame is arranged printing material and squeezes out dress
It sets, the discharge port of printing material extrusion device is vertically downward；Extrusion device is connect with printing material conveying pipeline.
The 3D printer transmission mechanism is suitable for the 3D printing of FDM rapid shaping technique and FFF heat of solution lamination method
Machine equipment.
The 3D printer transmission mechanism is suitable for ABS, PLA, PVA hot melt material, the 3D printer of metal material is set
It is standby.
Suspension type 3D printer transmission mechanism of the invention eliminates the frame-type design of existing 3D printer, is applicable in
It is printed in large item: four hitch points need to be only set when use on building inner top and side wall, pass through four stepping electricity
Suspension line is decontroled in machine cooperation tightening, is finally reached the purpose of control centre's rack.The transmission mechanism has structure simple, volume
Small and exquisite the advantages that but facilitating installation.
Detailed description of the invention
Fig. 1, Fig. 2 are structural schematic diagram of the invention.
Wherein, stepper motor 1, motor gear 2, transmission gear 3, worm screw 4 are driven turbine 5, and printing material conveying pipeline 6 is horizontal
To fixed block 7, vertically to fixed block 8, extrusion device 9.
Specific embodiment
Embodiment 1: suspension type 3D printer transmission mechanism, the mechanism include center rack, are provided with three in the rack of center
A vertically disposed stepper motor 1 and a horizontally disposed stepper motor 1, the motor shaft length of vertical step motor 1 differ,
Motor gear 2 is set at the top of motor shaft, and the motor shaft of horizontal step motor 1 is set as worm screw 4；Each motor gear 2 respectively with position
Three transmission gears 3 in top engage, and worm screw 4 engages with a transmission turbine 5 for being located at bottom, transmission gear 3 and transmission
5 side of turbine is fixed with drum, is wound with suspension line on drum；Transmission gear 3, transmission turbine 5 and the drum shares one
A bearing, bearing is interior to be arranged printing material conveying pipeline 6；Six horizontal direction fixed blocks 7, horizontal direction is arranged in the center rack outer rim
7 top of fixed block sets through-hole, the side two-by-two of horizontal direction fixed block 7, and the suspension line in superposed any drum passes through ipsilateral
Two horizontal direction fixed blocks 7, suspension line two ends are each attached on drum, and the suspension line of closure is extended out to side wall, are hanged
It hangs on the hook or fixed pulley of side wall；The center rack outer rim is also evenly arranged there are three vertically to fixed block 8, vertically
Through-hole is set on fixed block 8, three suspension lines are set in the drum of bottom, three one ends of suspension line are fixed on bottom drum
