Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
A kind of print head cleaning apparatus, applied to cleaning using easy polymerized organics as the printing device of ink, comprising:
Ontology 1, is formed with the cavity 2 for containing refrigeration module in ontology 1, a side wall of cavity 2 formed for
Print head in printing device carries out the heat exchange wall 21 of heat exchange.
Above-mentioned print head cleaning apparatus include ontology 1 and be set in ontology 1 for containing the cavity 2 of refrigeration module,
Refrigeration module is contained in cavity 2, a side wall of cavity 2 is formed for carrying out heat exchange with the print head in printing device
Heat exchange wall 21；When print head is blocked by high polymer, print head is contacted with the heat exchange wall 21 of cavity 2 and carries out heat exchange, by
It is metal material in print head, the response speed of high polymer is lower than for the response speed expanded with heat and contract with cold, therefore, in refrigeration module
In the short time of work, high polymer shrinkage effect is obvious and the shrinkage of metallic print head is negligible, and the height after shrinkage is poly-
Object can be relatively easy to be separated with print head, then can be clean by print head by subsequent cleaning.
Specifically, refrigeration module is liquid refrigerant.
Refrigeration module use liquid refrigerant, facilitate filling and replacement, and liquid refrigerant can be distributed evenly in it is whole
A 21 surface of heat exchange wall, so that heat exchange effect is more preferable.
Liquid refrigerant can use ethyl alcohol, and the temperature of used ethyl alcohol is needed than locating for print head in printing device
Environment temperature is low, and the temperature of used ethyl alcohol, which is 0 degree Celsius, to be advisable.
Refrigeration module can also be using solid cryogens and semiconductor chilling plates such as dry ice.
Specifically, ontology 1 is equipped with the replacement opening 3 for replacing liquid refrigerant and for blocking or opening more
Change the lid 4 of opening 3.
When refrigeration module uses liquid refrigerant, it is provided with the replacement for replacing liquid refrigerant on ontology 1 and is open
3, convenient for replacing liquid refrigerant at any time；It is provided with lid 4 in replacement opening 3, when needs inject or extract out liquid refrigerating
When agent, lid 4 is opened, lid 4 is covered after injection or extraction to block replacement opening 3, prevents liquid refrigerant careless
It flows out and pollutes printing device.
Refrigeration module can also use solid cryogen, when using dry ice, be provided on ontology 1 for replacing dry ice
Replacement opening 3 does not need that the lid for blocking or opening replacement opening 3 is arranged, prevents dry ice from issuing in air-proof condition
Raw explosion.
Refrigeration module can also use semiconductor chilling plate, semiconductor chilling plate is placed in cavity, and on the body
It is provided with the opening of the conducting wire of conveying semiconductor chilling plate, the conducting wire of semiconductor chilling plate is later half by opening connection external power supply
Conductor cooling piece is started to work, and can reach refrigeration effect after semiconductor chilling plate work.
Specifically, ontology 1 is equipped with for coating cavity 2 except the heat-shield mechanism 5 of the lateral wall of heat exchange wall 21.
Heat-shield mechanism 5, which is arranged, is prevented for preventing refrigeration module from carrying out heat exchange with the other parts in addition to print head
The only progress of extra heat exchange, so that the refrigeration effect of refrigeration module is more preferable.
Specifically, heat-shield mechanism 5 includes the vacuum chamber being set in ontology 1.
Using vacuum chamber as heat-shield mechanism 5, completely cuts off refrigeration module and the heat of the other parts in addition to heat exchange wall 21 passes
It leads, it is in addition easy to operate as heat-shield mechanism 5 using vacuum chamber so that refrigeration module not will do it extra heat exchange, it can be with
Vacuum pumping port for vacuumizing and the lid for blocking or opening vacuum pumping port are set on ontology 1, when needing to take out
Lid is opened when vacuum, when vacuumizing completion, with lid blocking vacuum pumping port to prevent air from entering.

Cavity is put into heat insulation foam in cavity.
Specifically, ontology 1 is equipped with the hitch assembly 6 for being hung on ontology 1 on printing device.
Ontology 1 is hung in printing device by hitch assembly 6, so that 21 side of heat exchange wall and print head are close to refrigeration
Module carries out refrigeration cool-down to print head by heat exchange wall 21, so that separating after high polymer shrinkage therein with print head, then leads to
Crossing subsequent cleaning can be clean by print head.
Specifically, hitch assembly 6 includes that two hanging rods 61 on ontology 1 and opposite, shape on each hanging rod 61 is arranged in
Cheng Youyi fixed bayonet 62.
Hitch assembly 6 includes being arranged on ontology 1 and two opposite hanging rods 61 and being set to consolidating on each hanging rod 61
Determine bayonet 62, after thering is the card slot matched with fixed bayonet 62, fixed bayonet 62 to be caught in card slot on printing device, print head cleaning
Device can be articulated in printing device.
Specifically, in ontology 1, the roof of cavity 2 forms heat exchange wall 21.
The roof of cavity 2 forms heat exchange wall 21, thus print head cleaning apparatus be mounted on the underface of print head with beat
It prints head and carries out heat exchange.
Specifically, heat exchange wall 21 is formed with side wall for coating the print head opening portion of printing device away from the surface of cavity
Recess.
When print head cleaning apparatus is mounted on the underface of print head, print head opening portion extend into the recessed of heat exchange wall 21
In the face of falling into, so that print head opening portion is coated by the recess of heat exchange wall 21 completely, print head can carry out sufficiently with heat exchange wall 21
Heat exchange, the high polymer in print head being capable of better shrinkage.
The present invention also provides a kind of printing devices, including print head, further include above-mentioned print head cleaning apparatus, by beating
Print head is able to clean after print head cleaning apparatus, and printing device is worked normally.
Obviously, those skilled in the art can carry out various modification and variations without departing from this hair to the embodiment of the present invention
Bright spirit and scope.In this way, if these modifications and changes of the present invention belongs to the claims in the present invention and its equivalent technologies
Within the scope of, then the present invention is also intended to include these modifications and variations.
