Show, do not show available data, it is uneven to represent temperature in printing pen tube 1.
The course of work using the printing pen tube 1 in the utility model embodiment is as follows:
Before printing, two terminal As of heating coil 3 and B are connected to alternating current circuit, and an alternation magnetic is generated in coil
, alternating magnetic field can generate current vortex in the low melting point liquid metal in printing pen tube 1, be melted by eddy current effect heat low
Melting point metals, the alternating electric field that heating coil 3 generates can form a poor efficiency with generating electromagnetic induction between buffer coil 4
Transformer.According to voltage device principle, the energy that heating coil 3 generates understands some and forms electricity in low melting point liquid metal
It is vortexed and becomes thermal energy, and another part energy can be transferred to buffer coil 4, be converted into thermal energy by buffer coil 4, so that buffering
The low melting point liquid metal that coil 4 coats generates current vortex and becomes thermal energy.To transmit most of energy of heating coil 3 not
To buffer coil 4, when slot 2 is in lifting state, the distance between heating coil 3 and buffer coil 4 should at least separate 3cm
More than.By adopting the above technical scheme, when printing pen tube 1 is in heated condition, heating coil 3 and buffer coil 4 can be simultaneously to them
Metal is heated at the two of cladding, and therefore low melting point liquid metal, prints pen tube 1 but also with the good capacity of heat transmission
Internal low melting point liquid metal is heated evenly.Internal structure for the eddy current effect for reinforcing heating coil 3, printing pen tube 1 can
Adaptability uses anti-convex structure, vortex heat effect when enhancing is heated in printing pen tube 1.
When printed, electromagnet 10, which is powered, adsorbs magnetic pole 11, then is pushed a slot 2 by connector 12, and printing pen tube 1 exists
Freely falling body in slot 2.Meanwhile two terminal As and B of heating coil 3 are connected to DC power supply, heating coil 3 at this time can
As an electromagnet, the magnetic field that heating coil 3 generates passes through buffer coil 4, when printing 1 freely falling body of pen tube, buffer coil 4
Since magnetic flux changes, electromagnetic induction occurs with heating coil 3 and generates the strength adsorbed mutually, printing pen tube is slowed down with this
1 falling speed.And when printing pen tube 1 and falling on substrate, the slight vibration of up and down direction can be generated, prints pen tube 1 upward
When vibration, buffer coil 4 occurs electromagnetic induction again between heating coil 3 and generates competing strength, is slowed down with this and is beaten
Print the upward vibration amplitude of pen tube 1.For the buffering effect for reinforcing buffer coil 4, for slot 2 in pressed status, printing pen tube 1 is certainly
By falling bodies on substrate, the distance between 4 top of 3 bottom of heating coil and buffer coil should be within 1cm at this time.Using upper
State technical solution, in printing, colliding impulse force on base material can effectively reduce printing pen tube 1, and pressure when printing can be with
It is manipulated by weight stack and the gravity for printing pen tube 1 itself.
After printing, slot 2 be lifted, erect therewith printing pen tube 1, two terminal As and B of heating coil 3 again with friendship
Become circuit communication, continues to heat liquid metal.Data receiver part 15 receives pen tube temperature and pen tip temperature is compared,
When pen tube temperature reaches setting numerical value, if larger with pen tip temperature deviation, enter constant temperature mode, i.e., progress power is low adds
Warm status can start to print when pen tube temperature and pen tip temperature remain basically stable.
In the above-mentioned course of work, the distance controlling of heating coil and buffer coil is a relative complex process,
Influence factor has thickness, the number of turns, the magnetic permeability of low melting point liquid metal of coil etc..When the distance of heating coil and buffer coil
When too far, buffer coil is unable to reach good buffering effect；When the distance of heating coil and buffer coil is too close, two lines
Circle system will become the higher transformer of transformation efficiency again, and most of power of heating coil can be captured by buffer coil at this time.
Therefore, when the low melting point liquid metal magnetic permeability of selection is higher, then the distance of heating coil and buffer coil should be zoomed out accordingly,
When the magnetic permeability of the low-melting-point metal of selection is lower, then the distance of heating coil and buffer coil should accordingly further.According to beating
The difference of the type for the low melting point liquid metal selected when print, the distance between heating coil and buffer coil are also different, therefore,
The structure for printing pen tube 1 will be also arranged using corresponding adaptability.
Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should
Understand: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of
Technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical new
The range of each embodiment technical solution of type.
