The two guide pins 153 are in sliding contact with the inner wall of the elliptical groove 156. When the rotating disk 155 is controlled to rotate, the two guide pins 153 can be controlled to slide along the elliptical groove 156, so that the two limit bars 152 can be controlled to move in a direction close to each other, thereby releasing the limit on the mounting plate 15. At the same time, when the rotating disk 155 is released, the two limit bars 152 can be controlled to reset themselves under the cooperation of the torsion spring 157 and the rotating pin 154, so that the rapid limit operation of the mounting plate 15 can be realized; In order to facilitate the rapid installation of the shell 1 at the desired position in the printer, and also facilitate the rapid disassembly of the shell 1, a mounting column 4 with a convex cross-section is fixedly installed on the side of the shell 1 away from the sensing chip 13, and a circular limiting plate 41 is fixedly installed on the thin end of the mounting column 4. A guide plate 1 42 and a guide plate 2 43 are slidably installed on the mounting column 4 at a position of the limiting plate 41 close to the side of the shell 1. The guide plate 1 42 and the guide plate 2 43 are fixedly connected. The side of the limiting plate 41 away from the shell 1, the side of the guide plate 1 42 close to the shell 1, and the side of the guide plate 2 43 away from the guide plate 1 42 are all inclined. A circular groove is opened on the side of the limiting seat 44 close to the shell 1, a spring 3 47 is fixedly installed on the inner wall of the circular groove, and a plurality of L-shaped card plates 4 are slidably installed on the inner wall of the circular groove 5. Multiple card plates 45 are arranged radially. A spring 2 46 is fixedly installed on one side of the card plate 45 close to the outer peripheral surface of the limiting seat 44. The spring 2 46 is fixedly connected to the outer peripheral surface of the limiting seat 44. The card plate 45 is arranged at an inclined position on one side close to the limiting plate 41. The contour of the limiting plate 41 close to the shell 1 is adapted to the guide plate 2 43. The purpose is that 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, the guide plate 1 42 and the limiting plate 41 can be kept in contact with each other, so that the card plate 45 will not stay between the guide plate 1 42 and the limiting 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 limiting plate 41 and the right side of the card plate 45 are kept in contact with each other after installation, so as to ensure the accuracy of the installation position of the shell 1. 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 a driving shaft 3 is axially fixedly connected to the output shaft of the motor 31. A hollow ball 32 is rotatably installed on the driving shaft 3, and two rotating shafts 33 are rotatably installed on the hollow shaft. 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 at the top is rotatably connected to the strip plate 38. The two rotating shafts 33 have a diameter of A plurality of stirring rods 35 are fixedly installed, 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 support on the rotating shaft 33 is meshed with the bevel gear 34 on the driving shaft 3, so that the ink can be stirred. Two fixed bars 37 are radially fixedly installed on the rotating shaft 33 below, and scraper bars 371 are fixedly installed on the bottom sides of the two fixed bars 37, and the scraper bars 371 are adapted to the filter plate 151, so that the scraper bars 371 can be controlled to clean the top side of the filter plate 151 when the ink is stirred.

[0027] In this embodiment, in order to perform a more efficient stirring operation on 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.

[0028] 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.

[0029] 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 .

[0030] Working principle: When using this device, first open the box cover 11 and add a proper 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 abut 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.

[0031] During the printing process, the motor 31 starts and drives 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 bar 371 on the rotating shaft 33 below 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 ink output.

[0032] When disassembly is required, the shell 1 is controlled to be 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 plates one 42 and the guide plates two 43 are 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 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 bar 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.

[0033] 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 of the placement groove.

[0034] In addition, the device is also designed with a circular groove and a 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 the printing quality and stable operation of the equipment.

[0035] The above is a detailed introduction to an ink cartridge provided by the present invention. Specific embodiments are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core ideas of the present invention.
