Further, the protection mechanism 200 includes an ink cartridge mounting plate 210, the top ends of the placing plates 111 at both sides of the ink cartridge main body 114 are all mounted with the ink cartridge mounting plate 210, the side of the ink cartridge mounting plate 210 close to each other is all provided with a protection moving groove 211, the inside of the protection moving groove 211 is all slidably mounted with a sealing plate 213, both ends of the sealing plate 213 inside the ink cartridge mounting plate 210 are both mounted with a sliding block 212, the side of the ink cartridge mounting plate 210 close to the sliding block 212 is all provided with a sliding groove 214, and the sliding block 212 can extend to the inside of the sliding groove 214, the outer surface of the sealing plate 213 at the top end of the clamping ring 218 is mounted with a penetrating rod 220 in a penetrating manner, one side of the sealing plate 213 close to the penetrating rod 220 is provided with an auxiliary insertion groove 219, and the penetrating rod 220 extends to the inside of the auxiliary insertion groove 219, and the other end of the return spring 215 is connected with the inner wall of the ink cartridge mounting plate 210, a through rod 220 is provided at one side of one sealing plate 213, and one sealing plate 213 can be inserted into the other through rod 220, the worker draws the two sealing plates 213 together and fixes the sealing plate 213 after the worker closes by the cooperation between the through rod 220 and the auxiliary insertion slot 219, and the sealing plate 213 is clamped into the auxiliary insertion slot 219 by the through rod 220 to fix the closed sealing plate 213, so as to protect the ink cartridge main body 114 which is then sent into the printer main body 110, thereby preventing the circuit in the printer main body 110 from contacting with the ink cartridge main body 114, and further preventing the circuit in the printer main body 110 from being damaged, or the printer main body 110 from being damaged.

Further, the telescopic rods 216 are installed on the sides, close to each other, of the ink cartridge mounting plates 210 at the bottom ends of the sealing plates 213, the clamping rings 218 are installed on the sides, close to each other, of the telescopic rods 216, the clamping springs 217 are installed on the outer surfaces of the telescopic rods 216 between the clamping rings 218 and the ink cartridge mounting plates 210 in a sleeved mode, the clamping rings 218 are arc-shaped, and the ink cartridge main bodies 114 placed by workers are located through the elastic force action of the clamping springs 217, so that the situation that the printer main bodies 110 can deviate in the process of feeding the ink cartridge main bodies 114 into the printer main bodies 110 by the workers is avoided, the metal movable blocks 125 are difficult to insert into the rotating shafts 115 later, the placing plates 111 need to be drawn out by the workers, new placement is performed on the ink cartridge main bodies 114, and the workload of the workers is increased.

The working principle is as follows: when the worker replaces the ink cartridge main body 114 inside the printer main body 110, the worker pulls the placing plate 111 outward, then the worker lifts the penetrating rod 220 upward to separate the penetrating rod 220 from the auxiliary insertion groove 219, then the worker takes the used ink cartridge main body 114 out of the two clamping rings 218, and places the replaced electric ink cartridge main body 114 between the two clamping rings 218, so that the clamping rings 218 moving toward the middle by the elastic force of the clamping springs 217 clamp the ink cartridge main body 114 placed by the worker, thereby positioning the position of the ink cartridge main body 114, thereby preventing the situation that the metal movable block 125 cannot be accurately inserted into the rotating shaft 115 in the later use process, after the worker places the ink cartridge main body 114, the worker closes the two sealing plates 213 to the middle, so that the smaller sealing plate 213 is inserted into the other sealing plate 213, and is clamped into the auxiliary insertion slot 219 by the penetrating rod 220, so that the two sealing plates 213 are matched with each other, and the ink cartridge main body 114 placed by the worker is protected, thereby preventing the parts or lines inside the printer main body 110 from being damaged by the ink cartridge main body 114 when the worker pushes the placing plate 111 placed with the ink cartridge main body 114 back to the printer main body 110.

After the worker pushes the placing plate 111 on which the ink cartridge main body 114 is placed into the printer main body 110, the metal movable block 125 is inserted into the rotating shaft 115, and the first and second teeth 127 and 128 mounted on the metal movable block 125 are engaged with each other, so that the rotating shaft 115 is rotated in the same direction during the worker rotates the mounting shaft 124 using the motor, thereby rotating the parts mounted on the rotating shaft 115 inside the ink cartridge main body 114 in the same direction, and in order to prevent the rotating shaft 115 from being separated from the rotating shaft 115 due to centrifugal force when the metal movable block 125 rotates, the metal fixing ball 131 mounted in the rotating shaft 115 is engaged with the fixing spring 130 when the metal movable block 125 is inserted into the rotating shaft 115, therefore, the metal fixing ball 131 is clamped into the fixing groove 132, so that the metal movable block 125 can be accurately fixed in the rotating shaft 115, and the metal movable block 125 and the rotating shaft 115 are prevented from falling off.

When the motor drives the rotating shaft 115 to rotate through the metal movable block 125, the rotating rod 116 arranged on the rotating shaft 115 in the ink box main body 114 rotates, the attaching scraper 122 connected with the rotating rod 116 through the installing metal block 117 arranged in the installing metal block 117 by the installing metal block 117 arranged in the rotating shaft 115 is attached to the inner wall of the ink box main body 114, so that the attaching scrapers 122 on two sides are driven to clean the inner wall of the ink box main body 114 in the rotating process of the rotating rod 116, the quantity of the ink adhered to the inner wall of the ink box main body 114 is reduced, the service life of the ink box main body 114 is prolonged, meanwhile, the attaching scraper 122 can stir the inner part of the ink box main body 114 in the rotating process of the attaching scraper 122, and therefore, the ink in the ink box main body 114 can be prevented from being condensed together when the ink box main body 114 is not used for a long time, causing the ink outlet to be blocked.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
