Problems solved by technology
The main component of the ink is polymethyl methacrylate, a small molecular organic substance, which is susceptible to polymerization under the influence of ultraviolet light, temperature and other external conditions, and the resulting polymer blocks the print head. Therefore, in the actual production process, it will often pass through the cleaning basin to The print head is cleaned, and the ink in the print head that is in direct contact with the environment is ejected, and then the surface of the print head is wiped with blotting paper to clean the print head. However, when the device does not work for a long time, due to the long print head When exposed to the external environment for a long time, the ink in the print head will polymerize to form high polymers, which will seriously block the print head. It is cleaned from the print head, causing the print head to fail to eject ink normally, causing the inkjet printing equipment to fail to work normally, and affecting the effect of the film packaging process

Embodiment Construction
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0020] A printing head cleaning device, which is applied to cleaning printing equipment using easy-to-polymerize organic matter as ink, comprising:
[0021] The main body 1 is formed with a cavity 2 for accommodating a refrigeration module, and one side wall of the cavity 2 forms a heat exchange wall 21 for exchanging heat with a printing head in a printing device.
[0022] The above-mentioned print head cleaning device includes a body 1 and a cavity 2 arrange...

The invention relates to the technical field of ink-jet printing, and discloses a printing head cleaning device and printing equipment. The printing head cleaning device is used for cleaning the printing equipment taking easily-polymerized organic matter as printing ink and comprises a body; a containing cavity for containing a refrigeration module is formed in the body; and one side wall of the containing cavity forms a heat exchange wall used for exchanging heat with the printing head in the printing equipment. The printing head cleaning device has the advantages that a high polymer generated by polymerization of the printing ink is subjected to cooling and cold contraction so that the volume of the high polymer can be decreased, the blocking capability of the high polymer generated by polymerization of the printing ink can be reduced, the printing head can be cleaned up, and the printing equipment can work normally.
Description
technical field [0001] The invention relates to the technical field of inkjet printing, in particular to a printing head cleaning device and printing equipment. Background technique [0002] Flexible organic light-emitting diode devices usually adopt a thin-film packaging process. There will be an organic film layer in the film packaging layer. The organic film layer is formed in the inkjet printing equipment. The ink is sprayed onto the substrate through the printing head, and through natural leveling, Then it is passed to the ultraviolet curing equipment to form an organic film layer by ultraviolet curing. The main component of the ink is polymethyl methacrylate, a small molecular organic substance, which is susceptible to polymerization under the influence of ultraviolet light, temperature and other external conditions, and the resulting polymer blocks the print head. Therefore, in the actual production process, it will often pass through the cleaning basin to The print ...
