Description of the Invention: [Technical Profile of the Invention] [0001] The present invention relates to an inkjet printer. [Previous Art] [0002] An inkjet printer is a commonly used printing device. When inkjet printing a printed article, some ink may be sprayed outside the printed article, which is not only wasteful, but may also The surrounding objects cause pollution. [〇〇〇3] An ink jet printer' which includes a processing module, an ink jet head, an ink cartridge, a 0 recovery tray, and a recycling drum. Wherein, the processing module can control the inkjet head to eject ink after sucking ink from the ink cartridge. The recovery tray and the recovery bucket are sequentially disposed under the inkjet head, and the recovery tray is connected to the recycling pipeline. The surface area of the recovery tray is larger than the ejection surface of the inkjet head, and is sprayed on the printed object when the inkjet printer is in operation. The external ink will be received by the recovery tray and then flowed through the pipeline to the recovery tank for storage. [0004] Since the solvent of the ink of the inkjet printer is a volatile substance, the volatilization of the solvent during the recovery process may cause the recovered ink to have a high viscosity and cannot be directly poured into the ink cartridge to utilize 'otherwise, the ink may be blocked. Head or affect print quality. Generally, after the recovered ink in the recycling bin is accumulated to a certain amount, the operator takes out the recycling tub and re-uses the ink, which is complicated. Moreover, in the process of recovering the accumulated ink, the solvent is further volatilized, which increases the difficulty and cost of recycling. SUMMARY OF THE INVENTION [0005] In view of the above, it is necessary to provide an ink jet printer that can recycle recycled ink. 098141094 Form No. A0101 Page 3 / Total 1 page 0992070509-0 201119879 [0007] [0009] [0009] [0009] An inkjet printer comprising an inkjet head, a processing module, and an inkjet head A tray for ink cartridges and ink recovery. The ink jet printer also includes a viscosity measuring device disposed on the ink cartridge and a viscosity adjusting device coupled to the ink cartridge. The viscosity measuring device and the viscosity adjusting device are both connected to the processing module. The processing module stores a viscosity upper limit value, and the viscosity measuring device measures the viscosity value of the ink in the ink cartridge and sends it to the processing module. The processing module compares the viscosity value with the viscosity upper limit value. When the viscosity value exceeds the viscosity upper limit value, the processing module controls the viscosity adjusting device to adjust the viscosity of the ink in the ink cartridge. The recovered ink of the ink jet printer of the present invention directly flows back into the ink cartridge. When the overall viscosity of the ink in the ink cartridge is increased, the viscosity of the ink cartridge is measured by a viscosity measuring device and the data is fed back to the processing mold. The processing module controls the viscosity adjusting device to adjust the viscosity in the ink cartridge, so that the inkjet head can normally eject ink. That is, an ink automatic circulation system is formed inside the inkjet printer, and the recovered ink can be re-entered into the ink cartridge for recycling in time, without requiring additional operations by the operator. Moreover, the time for the recovered ink to be exposed to the outside air is relatively small, and the amount of solvent volatilization is small, and it is easy to adjust the viscosity below the upper limit of the viscosity. [Embodiment] Hereinafter, the ink jet printer of the present invention will be further described in detail with reference to the accompanying drawings and embodiments. Referring to Fig. 1, the ink jet printer 200 of the present invention comprises an ink jet head 21, an ink fountain 23, a process module 24, a recovery tray 25, a viscosity adjusting device 26, a viscosity measuring device 27, a filter 28, and a pump 29. [0010] 098141094 The processing module 24 is connected to the inkjet head 21, and the inkjet head 21 is connected by a pipe (not shown in the drawing form No. A0101, page 4/10 pages 0992070509-0 201119879 [0011] ο [0012] Ο [(8) 13] 098141094) is connected to the ink cartridge 23. Under the control of the processing module 24, the inkjet head 汲 can extract ink from the ink cartridge and perform nozzle coating on the workpiece to be processed. The recovery tray 25 is disposed adjacent to the ink jet (4) and communicates with the ink H23 by transporting (4). The recovery tray 25 includes a tray 251 and a flange 253 extending vertically outward from the edge of the tray (5). The area of the disk 251 is larger than the area of the ink jet head 21, so that the ink on the printed object is ejected onto the disk 251 or the flange 253 to become the recovered ink. These recovered inks are finally condensed into the ink cartridges 23 via the transfer tubes 3. Since the ink from the inkjet head 21 has a higher weave, in order to prevent the recovered ink from adhering to the inner tube wall of the delivery tube 30, the pump 29 is placed on the delivery tube 3, and is powered by the pump 29 to make the recovery tray 25 The recovered ink can flow all the way into the ink cartridge 23. The filter 28 is disposed on the wheel tube 3 at a position downstream of the pump 29 to filter out impurities in the recovered ink. The viscosity measuring device 27 is disposed on the ink £23 and is in contact with the processing module (4). Viscosity measuring device 27 can measure the viscosity value of water within £23 and send the viscosity value to processing module 24. In the present embodiment, the viscosity measuring device 27 is composed of a viscometer (not shown) gray-digital conversion module (not shown). The viscometer can be one of a rotary viscometer, an ultrasonic viscometer, and a capillary viscometer. The viscosity adjusting device 26 includes an adjustment box 261 and a gas pump 263 connected to the adjustment box 261. A liquid viscosity adjuster 265 is contained in the adjustment tank 261. The air pump 263 is connected to the processing module 24, and the adjusting box 261 and the ink cartridge 23 are connected by a pipe (not shown). The processing module 24 can control the operation of the air pump 263, and increase the air pressure in the adjusting box 261 to make the viscosity adjusting agent 265. By the pipe flowing into the ink E23' to adjust the viscosity of the ink in the ink £23, no form number A0101, page 5 / total page 0992070509-0 201119879, the adjustment box 261 and the ink cartridge 23 have the same internal pressure, the viscosity adjuster 265 It will not flow into the ink cartridges. Of course, the air pump 263 of the viscosity adjusting device 26 can also be omitted, and a solenoid valve controlled by the processing module 24 is disposed on the pipeline connecting the adjusting box 261 and the ink cartridge 23, and the adjusting box 261 is disposed above the ink cartridge 23. When the solenoid valve is opened, the viscosity modifier 265 flows from the adjustment box 261 into the ink cartridge 23, and also adjusts the viscosity of the ink in the ink cartridge 23. [0014] In operation, the ink viscosity upper limit value is first set on the processing module 24. The ink jet head 21 starts to eject ink, and a part of the ink is ejected onto the recovery tray 25 to recover ink. These recovered inks are filtered by the pump 28 through the filter 28 and then flow into the ink cartridge 23 by the pump 29. Due to the volatilization of the solvent during the recovery process, the viscosity of these recovered inks is high, and mixing with the ink in the ink cartridge 23 causes an increase in the viscosity of the ink in the ink cartridge 23. The viscosity measuring device 27 continuously measures the viscosity value in the ink cartridge 23 and sends it to the processing module 24. The processing module 24 compares the viscosity value with the ink viscosity upper limit value. If the viscosity value is less than the ink viscosity upper limit value, the instruction is not executed; if the viscosity value is greater than the ink viscosity upper limit value, the processing module 24 activates the air pump 263. The air pressure in the adjusting box 261 is increased, and the viscosity adjusting agent 265 is sent into the ink cartridge 23 to reduce the viscosity of the ink in the ink cartridge 23 until the ink viscosity value is less than the upper limit value of the ink viscosity. [0015] An agitator 33 having a plurality of blades (not shown) may be disposed in the ink cartridge 23. When the inkjet printer 200 is in operation, the blades of the agitator 33 are continuously rotated to flow into the ink cartridge 2 The recovered ink is evenly mixed with the ink remaining in the ink cartridge. When a viscosity adjusting agent 265 is added, the agitator 33 can also sufficiently mix the viscosity adjusting agent 265 with the ink to increase the ink 098141094.

Ο [] The recovered ink flows into the ink cartridge 2 3 , causing the viscosity of the ink cartridge 23 to be measured by the viscosity measuring device 27 and the data is fed back to the processing module 24 when the ink in the ink cartridge 2 3 is increased in overall. The processing module 24 controls the viscosity adjusting device 26 to adjust the viscosity in the ink cartridge 23 so that the ink jet head 21 can normally ink. Thus, an 'automatic circulation system is formed inside the inkjet printer 2'. The recovered ink can be re-entered into the ink cartridge 23 for recycling, without the need for additional operations by the operator, and the time for the recovered ink to be exposed to the outside air is compared. Short, less solvent volatilization, easy to adjust its viscosity below the upper viscosity limit.
