A kind of material silk detection device of 3D printer
Technical field
This utility model relates to 3D printing technique field, is specifically related to the material silk detection device of a kind of 3D printer.
Background technology
3D printer is a kind of machine of a kind of accumulation manufacturing technology, i.e. rapid shaping technique.The work of 3D printer is former
Reason is that data and raw material are placed in 3D printer, and the model of required printing can be printed layer by layer by printer according to program
Out.Wherein the conventional raw material of 3D printer is PLA plastics consumptive material, and this kind of consumptive material is wound around on a charging tray frame more, is beating
During print, user cannot judge the type of material silk in magazine, it is impossible to detect the most normal wire vent of material silk, material silk surplus with
And judge to expect whether silk makes moist, and causes 3D printer sky to beat and expect the situation that silk cannot use.
Therefore need a kind of scheme to solve the problems referred to above.
Summary of the invention
For solve the problems referred to above, this utility model provide one can point out simultaneously material silk type information, detection fracture of wire,
Judge expect silk surplus and judge to expect the method whether silk makes moist.
Equipment and technology scheme of the present utility model is: the material silk of a kind of 3D printer detection device, including magazine module and
Detection module;Described magazine module includes magazine, charging tray, irradiation modules and data memory module;Described data memory module leads to
Oversampling circuit plate a is installed on inside described magazine, and described charging tray, irradiation modules are installed on inside described magazine.Described data store
Module is EEPROM, has the type information of described charging tray feeding silk.Described irradiation modules is variable color silica gel, can prevent described material
In box, material silk makes moist;In described irradiation modules during the variable color of variable color silica gel, described irradiation modules needs to change.Described detection module includes
Photoelectric encoder and detection plate;Described photoelectric encoder is installed on fixed plate by grating rotating shaft, and described detection plate passes through circuit
Plate b is installed on described fixed plate.Described photoelectric encoder is used for detecting described charging tray feeding silk fracture of wire and whether and judges described
The surplus of charging tray feeding silk.

Detailed description of the invention
In order to it is to be expressly understood that technology contents of the present utility model, illustrate especially exemplified by following instance.
Refering to shown in Fig. 1 and Fig. 2, the utility model discloses the material silk detection device of a kind of 3D printer, this device by
Magazine module 1 and detection module 1(1) constitute, magazine module 1 by magazine (magazine left cover 2 and magazine right cover 3), charging tray 4, be dried
Module 19 and data memory module 9(this programme use EEPROM) constitute, test module 1(1) by photoelectric encoder 14 and detection
Plate 15 is constituted.Charging tray 4 is installed in magazine left cover 2, is positioned at magazine 1 internal;Data memory module 9(this programme uses EEPROM)
It is installed on magazine 1 internal by circuit board a8;Photoelectric encoder 14 is installed in fixed plate 18 by grating rotating shaft 13, detects plate
15 are installed in fixed plate 18 by circuit board b16.During work, knock-pin 11 upwards causes gear 7 pressing material silk 17, makes material silk
17 from material fiber tube 5 process, and material silk outlet 6 is out;Data Input Interface 10 on circuit board a8 is beaten with 3D by interface contact 20
Print machine connects, in advance input material silk 17 type, is stored in data memory module 9(this programme and uses EEPROM) in, can be to user
The type of prompting material silk 17.Material silk 17 from magazine 4 out after, arrive detection module 1(1);Machine shaft 12 rotates and drives light
Grid rotating shaft 13 rotates, and material silk 17 passes through, and photoelectric encoder 14 is when rotating, and detection plate 15 output signal is not (if material silk 17 passes through
Photoelectric encoder 14, detects plate 15 then non-output signal), thus material silk 17 whether fracture of wire can be detected;According to photoelectric encoder 14
The number of turns turned over, it is thus achieved that expects silk 17 uses length, thus calculates the residue length of discharging silk, determines the replacing construction of material silk.
For variable color silica gel in irradiation modules 19, for expecting being dried of silk 17, when variable color silica gel variable color, then irradiation modules 19 needs to change.
