The ink container 100 includes a tank body 110 and an ink removing body 120.

As shown in fig. 2, the tank main body 110 includes a first side plate 111 and a second side plate 112 spaced apart from and disposed opposite to the first side plate 111, an ink storage area 113 with an open top is formed between the first side plate 111 and the second side plate 112, the printing roller 200 is rotatable relative to the tank main body 110, and the bottom of the printing roller 200 extends into the ink storage area 113, wherein a side of the printing roller 200 close to the first side plate 111 is a roll-out side, and a side of the printing roller 200 close to the second side plate 112 is a roll-in side.

Specifically, the ink container 100 has a hollow structure with an ink storage area 113, and the top of the ink container 100 is open. The first side plate 111 and the second side plate 112 are spaced and disposed opposite to each other, and the ink storage area 113 is formed between the first side plate 111 and the second side plate 112. The printing roller 200 is rotatably disposed above the ink container 100, and the bottom of the printing roller 200 extends into the ink storage area 113. When the printing roller 200 rotates, the moving direction of the side of the printing roller 200 close to the first side plate 111 is the direction of turning out from the ink storage area 113, and the moving direction of the side of the printing roller 200 close to the second side plate 112 is the direction of turning in to the ink storage area 113, in other words, the rotating direction of the side of the printing roller 200 close to the first side plate 111 is upward, and the rotating direction of the side of the printing roller 200 close to the second side plate 112 is downward.

The ink impurity removing body 120 is arranged on the top of the second side plate 112, the ink impurity removing body 120 comprises a scraping plate 121, a baffle 122 and a filter screen 123, the scraping plate 121 is arranged towards the printing roller 200, the baffle 122 is arranged on the top of the scraping plate 121 and is matched with the scraping plate 121 to form a recovery tank 124, the scraping plate 121 is provided with a return opening 1211, the return opening 1211 is used for communicating the recovery tank 124 with the ink storage area 113, and the filter screen 123 is arranged in the recovery tank 124.

When the ink on the printing roller 200 is used, some ink may remain on the surface of the printing roller 200, and impurities may adhere to the surface of the remaining ink, and the scraper 121 is used to scrape the remaining ink. The baffle 122 is disposed on the scraper 121, and cooperates with the scraper 121 to form a recovery tank 124, and the ink scraped by the scraper 121 flows into the recovery tank 124, then is filtered by the filter screen 123, and finally enters the ink storage area 113 through the return opening 1211 for further use. After the ink entering the recovery tank 124 is filtered by the filter screen 123, impurities mixed in the ink can be filtered, so that the ink flowing back to the ink storage area 113 can be prevented from polluting the original ink in the ink storage area 113.

The filter screen 123 may be selected according to the size of the impurities. It is only necessary to ensure that the pores of the filter screen 123 are smaller than the diameter of the impurities.

Further, an avoiding gap is formed between the scraper 121 and the printing roller 200, and the width of the avoiding gap is larger than 0.05mm and smaller than 0.2 mm. Thus, the blade 121 does not directly contact the printing roller, and the blade 121 is prevented from affecting the normal rotation of the printing roller 200. Further, since the ink adheres to the surface of the printing roller 200, the ink itself has a certain thickness, and the width of the clearance between the squeegee 121 and the printing roller is set to be 0.05mm to 0.2mm, thereby ensuring that the ink on the surface of the ink layer adhering to the surface of the printing roller 200 is scraped off.

Further, the length of the blade 121 is greater than or equal to the length of the printing roller 200. In this way, when the printing roller 200 is rotating, the blade 121 can scrape off ink remaining on various portions of the surface of the printing roller 200, and prevent the remaining ink partially mixed with impurities from entering the ink storage area 113.

Further, the blade 121 is disposed obliquely, and one end of the blade 121 close to the printing roller 200 is higher than one end of the blade 121 far from the printing roller 200. Thus, when the ink is scraped off by the blade 121, the ink flows toward the return opening 1211 along the blade 121 by gravity.

As shown in fig. 2, in one embodiment, the ink receptacle 100 further includes a splash guard 130, and the splash guard 130 is disposed on top of the first side plate 111. When the printing roller 200 rotates, the printing roller 200 drives the ink in the ink storage area 113 to splash, and the splash-proof body 130 is used for preventing the splashed ink from splashing out of the ink storage area 113 to pollute the surrounding environment.

Specifically, the splash guard 130 includes a transverse splash guard 131 and an arc splash guard 132 connected to the transverse splash guard 131, and the arc splash guard 132 is spaced from and opposite to the ink impurity remover 120. When the printing roller 200 rotates, a part of the ink may splash along a tangent line of the printing roller 200, the transverse splash guard 131 may prevent a part of the ink from splashing, and the arc-shaped splash guard 132 may also prevent a part of the ink from splashing.
