[0026] This detailed implementation manner is a print head cleaning device, and its structural schematic diagram is as Figures 1 to 4 shown, including a processing table 1, a first adjustment mechanism 2 is installed on the upper and lower sides of the top end of the processing table 1.

A second motor 34 is installed on the other side of the two lower mounting frames 31, and the output end of the second motor 34 is connected to a connecting clamping block 35. The staff pre-horizontally places the print head to be cleaned in the middle of one of the lower mounting frames 31 below the annular disc 24. Then, the second cylinder 32 is started so that the movable clamping block 33 at its end can cooperate with the connecting clamping block 35 to clamp the print head therein to form a fixation. Then, the staff starts the first motor 23 to rotate the annular disc 24, so that the position of the lower mounting frame 31 where the print head is just placed can be translated to the opening above the cleaning frame 4. Immediately, the first cylinder 21 is started to lower the annular disc 24 and the lower mounting frame 31, so that the position of the print head can enter the inside of the cleaning frame 4 to perform subsequent cleaning operations. It is worth mentioning that two sets of clamping mechanisms 3 are provided and arranged oppositely. When the print head clamped by one of the clamping mechanisms 3 is in the processing state, the staff can add a new print head into the other clamping mechanism 3, so as to achieve the purpose of seamless cleaning.

[0028] In addition, the cleaning mechanism 5 includes a side mounting frame 51, and the side mounting frame 51 is fixed to the inner lateral side of the cleaning frame 4. A heating pipe 52 is installed in the middle of the side mounting frame 51. A cleaning component 53 is installed on the other inner lateral side of the cleaning frame 4. The cleaning component 53 includes a transmission lead screw 531, and the transmission lead screw 531 is installed on one inner side of the cleaning frame 4. One end of the transmission lead screw 531 is connected and installed with a third motor 532. A lead screw sliding sleeve 533 is screwed on the periphery of one side of the transmission lead screw 531. An installation frame 534 is fixedly installed inside the lead screw sliding sleeve 533. A guide rod 535 for guiding the movement of the installation frame 534 is fixed on one inner side of the cleaning frame 4. A third air cylinder 536 is installed inside the installation frame 534. The extending end of the third air cylinder 536 is connected with a wiping head 537. A micro diaphragm pump 538 is installed above the lead screw sliding sleeve 533. One of the discharge ends of the micro diaphragm pump 538 is connected with a diverging pipe rack 539. The two ports of the diverging pipe rack 539 are respectively connected with exhaust pipe racks 5310. A collection mechanism 54 is installed on one inner vertical side of the cleaning frame 4. The collection mechanism 54 includes a sliding groove 541, and the sliding groove 541 is opened on one inner side of the cleaning frame 4. A collection guide frame 542 is slidably arranged inside the sliding groove 541. One end of the collection guide frame 542 is fixed with a side fixing block 543. First magnetic blocks 544 are fixedly installed on both inner sides of the two ends of the side fixing block 543. Second magnetic blocks 545 are fixed on both sides of the cleaning frame 4 at the port of the sliding groove 541. The first magnetic blocks 544 and the second magnetic blocks 545 are magnetically fixedly connected. When the print head is inside the cleaning frame 4, the heating pipe 52 on one inner side thereof is in a heating state, so as to heat one side of the print head, thereby reducing the viscosity of the stains and sludge on this side. After this side is heated, the second motor 34 can be started so that the print head clamped inside the connecting clamp block 35 can be flipped, making its heated surface face the cleaning component 53, and the unheated surface on the other side is flipped to the heating area. Then the third motor 532 is started to make the transmission lead screw 531 rotate. At this time, the lead screw sliding sleeve 533 acting with the lead screw will drive the installation frame 534 to move horizontally in cooperation with the guiding of the guide rod 535. Since the third air cylinder 536 is arranged inside the installation frame 534 and the end of the third air cylinder 536 is connected with the wiping head 537, the wiping head 537 can effectively wipe the stains on the heated print head surface. After wiping along the surface, the position of the wiping head 537 will enter above the collection guide frame 542 through the above transmission structure. At this moment, the micro diaphragm pump 538 is started, and the flushing gas will enter the diverging pipe rack 539 along with the pump exhaust end and enter the exhaust pipe racks 5310 through diversion. The exhaust ports of the two exhaust pipe racks 5310 will flush the stains and sludge left on both wiping areas of the wiping head 537 into the collection guide frame 542. Subsequently, the operator can pull out the collection guide frame 542 from the cleaning frame 4 through the sliding groove 541 for corresponding cleaning.

[0029] Working principle: The staff pre - horizontally place the print head to be cleaned in the middle of one of the lower mounting frames 31 below the annular disk 24. Then, the second cylinder 32 is activated so that the movable clamping block 33 at its end can cooperate with the connecting clamping block 35 to clamp the print head to form a fixation. Then, the staff activates the first motor 23 to rotate the annular disk 24, so that the position of the lower mounting frame 31 where the print head is just placed can be translated to the opening above the cleaning frame 4. Immediately, the first cylinder 21 is activated to lower the annular disk 24 and the lower mounting frame 31, so that the position of the print head can enter the cleaning frame 4 for subsequent cleaning operations. It is worth mentioning that there are two sets of clamping mechanisms 3 which are arranged oppositely. When the print head clamped by one of the clamping mechanisms 3 is in the processing state, the staff can add a new print head into the other clamping mechanism 3, so as to achieve the purpose of seamless cleaning. Finally, when the print head is inside the cleaning frame 4, the heating tube 52 on one side inside it is in a heating - up state, so as to heat - treat one side of the print head, thereby reducing the viscosity of the stains and sludge on this side. After this side is heated, the second motor 34 can be activated so that the print head clamped inside the connecting clamping block 35 can be flipped, making the heated surface face the cleaning component 53, and the un - heated surface on the other side is flipped to the heating area. Then, the third motor 532 is activated to rotate the transmission lead screw 531. At this time, the lead screw sliding sleeve 533 acting with the lead screw will drive the mounting frame 534 to move horizontally along with the guidance of the guide rod 535. Since the mounting frame 534 is provided with a third cylinder 536, and the end of the third cylinder 536 is connected to the wiping head 537, the wiping head 537 can effectively wipe the stains on the heated print head surface. After wiping along the surface, the position of the wiping head 537 will enter above the collection guide frame 542 through the above - mentioned transmission structure. At this moment, the micro diaphragm pump 538 is activated, and the flushing gas will enter the branch pipe frame 539 following the pump exhaust end and enter the exhaust pipe frame 5310 through branching. The exhaust ports of the two exhaust pipe frames 5310 will flush the stains and sludge left on the two wiping sides of the wiping head 537 into the collection guide frame 542. The staff can then use the sliding groove 541 to actively pull out the collection guide frame 542 from the cleaning frame 4 for corresponding cleaning.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] Finally, it should be noted that the above - mentioned are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
