Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
A kind of print head cleaning apparatus, applied to printing device of the cleaning using easy polymerized organics as ink, including：
Body 1, formed with the cavity volume 2 for containing refrigeration module in body 1, a side wall of cavity volume 2 formed for
Printhead in printing device carries out the heat exchange wall 21 of heat exchange.
Above-mentioned print head cleaning apparatus includes body 1 and the cavity volume 2 for being used to contain refrigeration module being arranged in body 1,
Refrigeration module is contained in cavity volume 2, a side wall of cavity volume 2 is formed for carrying out heat exchange with the printhead in printing device
Heat exchange wall 21；When printhead is blocked by high polymer, printhead is contacted into carry out heat exchange with the heat exchange wall 21 of cavity volume 2, by
It is metal material in printhead, the response speed of high polymer is less 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 positive effect and the shrinkage of metallic print head can be neglected, and the height after shrinkage gathers
Thing can be relatively easy to be separated with printhead, then can be cleaned printhead totally by follow-up cleaning.
Specifically, refrigeration module is liquid refrigerant.
It is whole that refrigeration module uses liquid refrigerant, convenient filling and replacing, and liquid refrigerant to be distributed evenly in
The individual surface of heat exchange wall 21 so that heat exchange effect is more preferable.
Liquid refrigerant can use ethanol, and the temperature of used ethanol is needed than residing for printhead in printing device
Environment temperature is low, and the temperature of used ethanol is advisable for 0 degree Celsius.
Refrigeration module can also use solid cryogen and the semiconductor chilling plates such as dry ice.
Specifically, body 1, which is provided with, is used to change the replacing opening 3 of liquid refrigerant and for blocking or opening more
Change the lid 4 of opening 3.
The replacing opening for being used for changing liquid refrigerant is provided with when refrigeration module uses liquid refrigerant, on body 1
3, it is easy to change liquid refrigerant at any time；Lid 4 is provided with opening 3 is changed, when needs inject or extracted out liquid refrigerating
During agent, lid 4 is opened, lid 4 is covered after injection or extraction and changes opening 3 to block, prevents that liquid refrigerant is careless
Flow out and pollute printing device.
Refrigeration module can also use solid cryogen, when using dry ice, be provided with body 1 for changing dry ice
Change opening 3, it is not necessary to be provided for blocking or open the lid of replacing opening 3, prevent dry ice from being issued in air-proof condition
Raw blast.
Refrigeration module can also use semiconductor chilling plate, and semiconductor chilling plate is positioned in cavity volume, and on body
The opening of the wire of conveying semiconductor chilling plate is provided with, the wire of semiconductor chilling plate is later half by opening connection external power source
Conductor cooling piece is started working, and refrigeration is can reach after semiconductor chilling plate work.
Specifically, body 1, which is provided with, is used to coat heat-shield mechanism 5 of the cavity volume 2 except the lateral wall of heat exchange wall 21.
It is for preventing refrigeration module from carrying out heat exchange with the other parts in addition to printhead, preventing to set heat-shield mechanism 5
The only progress of unnecessary heat exchange so that the refrigeration of refrigeration module is more preferable.
Specifically, heat-shield mechanism 5 includes the vacuum chamber being arranged in body 1.
Using vacuum chamber as heat-shield mechanism 5, isolation refrigeration module and the heat biography of the other parts in addition to heat exchange wall 21
Lead so that refrigeration module will not carry out unnecessary heat exchange, easy to operate as heat-shield mechanism 5 using vacuum chamber in addition, can be with
The vacuum pumping port vacuumized and the lid for blocking or opening vacuum pumping port are provided on body 1, when needs are taken out
Lid is opened during vacuum, when vacuumizing completion, blocks vacuum pumping port with lid to prevent air from entering.
Heat-shield mechanism 5 can also use heat insulation foam, and heat-shield mechanism 5 includes being arranged to be used to place heat insulation foam on body 1
Cavity, heat insulation foam is put into cavity.
Specifically, body 1 is provided with the hitch assembly 6 for being used for being hung on body 1 on printing device.
Body 1 is hung in printing device by hitch assembly 6 so that the side of heat exchange wall 21 and printhead are close to refrigeration
Module carries out refrigeration cool-down by heat exchange wall 21 to printhead so that separates, then leads to printhead after high polymer shrinkage therein
Later continuous cleaning can clean printhead clean.
Specifically, hitch assembly 6 includes being arranged on body 1 and relative two pegs 61, shape on each peg 61
Cheng Youyi fixed bayonet socket 62.
Hitch assembly 6 includes being arranged on body 1 and relative two pegs 61 and is arranged at consolidating on each peg 61
Determine bayonet socket 62, after thering is the neck being engaged with fixed bayonet socket 62, fixed bayonet socket 62 to be caught in neck on printing device, printhead cleaning
Device can be articulated in printing device.
Specifically, in body 1, the roof of cavity volume 2 forms heat exchange wall 21.
The roof of cavity volume 2 forms heat exchange wall 21, therefore print head cleaning apparatus is mounted on the underface of printhead with beating
Print head and carry out heat exchange.
Specifically, heat exchange wall 21 is used for the printhead opening portion for coating printing device away from the surface of cavity formed with side wall
Depression.
When print head cleaning apparatus is mounted on the underface of printhead, printhead opening portion extend into the recessed of heat exchange wall 21
In the face of falling into so that printhead opening portion is coated by the depression of heat exchange wall 21 completely, and printhead can be carried out fully with heat exchange wall 21
Heat exchange, the high polymer in printhead being capable of more preferable shrinkage.
Present invention also offers a kind of printing device, including printhead, in addition to above-mentioned print head cleaning apparatus, by beating
Printhead is able to cleaning totally after print head cleaning apparatus, and printing device is able to normal work.
Obviously, those skilled in the art can carry out various changes and modification without departing from this hair to the embodiment of the present invention
Bright spirit and scope.So, if these modifications and variations of the present invention belong to the claims in the present invention and its equivalent technologies
Within the scope of, then the present invention is also intended to comprising including these changes and modification.
