The contour of the side of the limit plate 41 close to the shell 1 is adapted to the guide plate 2 43. The purpose is to enable the guide plate 1 42 to maintain contact with the limit plate 41 when the guide plate 1 42 and the guide plate 2 43 move to the right side of the card plate 45 and then move to the left side of the left card plate 45, so that the card plate 45 will not stay between the guide plate 1 42 and the limit plate 41 after being guided by the guide plate 1 42. At the same time, the setting of the spring 3 47 can ensure that the limit plate 41 and the right side of the card plate 45 maintain abutment after installation, thereby ensuring the accuracy of the installation position of the shell 1.

[0037] In order to prevent the ink from settling or stratifying due to long-term standing, and at the same time ensure the effective filtration of the ink by the filter plate 151 and avoid the deterioration of the ink uniformity, a motor 31 is fixedly installed on the partition 12, and the output shaft of the motor 31 is axially fixedly connected to the drive shaft 3, and a hollow ball 32 is rotatably installed on the drive shaft 3, and two rotating shafts 33 are rotatably installed on the hollow ball 32. The two rotating shafts 33 are coaxially arranged, and the partition 12 and the inner wall of one side of the shell 1 are fixedly installed with the same strip plate 38. The rotating shaft 33 located above is rotatably connected to the strip plate 38, and the two rotating shafts 33 have a diameter of A plurality of stirring rods 35 are fixedly installed thereto, and the ends of the two rotating shafts 33 and the driving shaft 3 that are close to each other extend into the hollow ball 32 and are fixedly sleeved with bevel gears 34 respectively. The bevel gear 34 on the rotating shaft 33 is engaged with the bevel gear 34 on the driving shaft 3, and can stir the ink. Two fixed bars 37 are radially fixedly installed on the rotating shaft 33 below, and scraping bars 371 are fixedly installed on the bottom sides of the two fixed bars 37, and the scraping bars 371 are adapted to the filter plate 151, so that the scraping bars 371 can be controlled to clean the top side of the filter plate 151 when the ink is stirred.

[0038] In this embodiment, in order to more efficiently stir the ink near the filter plate 151 , a plurality of vertical rods 36 are radially fixedly mounted on the plurality of stirring rods 35 located at the bottom.

[0039] In this embodiment, in order to facilitate the rapid positioning of the box cover 11 and the rapid disassembly and assembly of the box cover 11, a circular groove is opened on the top of the shell 1, and the box cover 11 is snap-fitted into the circular groove and threadedly connected to the shell 1 through bolts.

[0040] In this embodiment, in order to ensure the sealing of the connection between the box cover 11 and the shell 1, a sealing ring is fixedly installed on the top of the shell 1, and the top side of the sealing ring is movably sealed against the bottom inner wall of the box cover 11.

[0041] Working principle:

[0042] When using this device, first open the box cover 11 and add an appropriate amount of ink to the right side of the partition 12 in the shell 1, then close the box cover 11 and fix it, then open the printer cover and align the upper limit plate 41 of the device with the circular groove on the limit seat 44 in the printer and push it in. During this process, the limit plate 41 contacts the card plate 45 and pushes multiple card plates 45 away from the axis of the circular groove until the limit plate 41 moves to the right side of the card plate 45. Under the action of spring three 47, the limit plate 41 can be abutted against the right side of the card plate 45. During the installation of the shell 1, the guard plate 2 is limited by the installation position space in the printer and will abut against the right side of the guard plate 2, so that during the pushing process of the shell 1, the guard plate 2 drives the slider to compress the spring one 23, and at the same time, the nozzle 14 can be cleaned under the action of the cleaning strip 24.

[0043] During the printing process, the motor 31 starts, driving the drive shaft 3 to rotate. Through the meshing transmission of the bevel gear 34, the two rotating shafts 33 rotate synchronously. The stirring rod 35 and the vertical rod 36 on the rotating shaft 33 fully stir the ink to prevent the ink from settling or stratification. At the same time, the scraper 371 located on the lower rotating shaft 33 rotates with the rotating shaft to clean the top side of the filter plate 151, ensuring the filtering effect of the filter plate 151 and maintaining the uniformity of the ink output.

[0044] When disassembly is required, the control shell 1 is pushed toward the mounting seat 44, so that the spring three 47 is compressed. At the same time, under the action of the guide plate two 43, the guide plate one 42 and the guide plate two 43 are both moved to the right side of the card plate 45. Then the shell 1 is pulled. Under the action of the guide plate one 42 and the card plate 45, the guide plate two 43 can be stuck into the right side position of the limit plate 41, so that the card plate 45 can directly jump over the limit plate 41, thereby realizing the rapid disassembly of the shell 1. During this process, the guard plate 2 is no longer restricted. The guard plate 2 will slide along the slide rod 22 under the action of the spring one 23, automatically reset and cover the nozzle 14 in the mounting groove, and prevent the nozzle 14 from being contaminated or damaged by the outside world.

[0045] When the mounting plate 15 and the filter plate 151 need to be disassembled, the two guide pins 153 are made to slide along the elliptical grooves 156 by rotating the turntable 155, thereby driving the two limit bars 152 to move toward each other, thereby releasing the limit on the mounting plate 15. At this time, the mounting plate 15 can be taken out from the placement groove.

[0046] In addition, the device is also designed with a circular groove and sealing ring structure, which tightly connects the box cover 11 to the shell 1 through bolts, and uses the sealing ring to achieve a good sealing effect, effectively preventing ink leakage or external impurities from entering the shell 1, ensuring printing quality and stable operation of the equipment.

[0047] The above describes in detail the ink cartridge provided by the present invention. Specific embodiments are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is intended only to facilitate understanding of the method and core concepts of the present invention. It should be noted that those skilled in the art may, without departing from the principles of the present invention, make various improvements and modifications to the present invention, and such improvements and modifications fall within the scope of protection of the claims of the present invention.
