Description

Technical Field

[0001] The utility model relates to the technical field of ink production, in particular to an ink mixing and stirring device. Background Art

[0002] With the rapid development of the printing industry, printing presses are developing towards multi-color, multi-functional and continuous processing. Ink is a mixture of color bodies, binders, fillers, additives and other substances. In the process of ink preparation, the raw materials need to be mixed and stirred to form a uniform mixture.

[0003] However, the traditional ink stirring equipment still has certain defects when in use. For example, the utility model patent with the authorization announcement number CN 211800223U discloses an ink mixing and stirring device. As a prior art, when in use, an inner filter cartridge, a plurality of blades and a stirring paddle are arranged inside the outer box body. When the ink is mixed and stirred evenly and then discharged, the above-mentioned multiple components and the inner wall of the outer box body and the inner wall of the inner filter cartridge will adhere to the ink, and the adhesion amount is large, resulting in a waste of material resources and great difficulty in cleaning. In addition, the solid particles filtered out by the inner filter cartridge will accumulate and aggregate for a long time, which will affect the filtering effect, and the cleaning process is also cumbersome, affecting the work efficiency. Therefore, we design an ink mixing and stirring device to solve the above technical problems. Utility Model Content

[0004] The purpose of the utility model is to provide an ink mixing and stirring device to solve the problems raised in the above background technology.

[0010] As a further preferred solution of the utility model: a feed hopper is provided on the top of the outer side wall of the mixing box.

[0011] As a further preferred solution of the utility model: the length of the scraper rod is equal to the height of the inner wall of the mixing box.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the present device, when the annular filter frame is rotated to a state perpendicular to the ink flow direction, the abutment block abuts against the corresponding fixed block. At the same time, the magnet block A and the corresponding magnet block B fit together and adsorb each other, so as to fix the position of the annular filter frame at this time, so as to facilitate the filtering and interception of fixed particles during discharge. When the filter screen needs to be cleaned, the staff needs to screw and install the filter sleeve to the bottom of the L-shaped discharge pipe in advance, and then the staff can turn the annular filter frame by turning the knob to turn the annular filter frame over. Note that the annular filter frame is not exactly turned over 180 degrees at this time, but its turning angle is sufficient for the cleaning operation. At this time, when unloading, the flowing ink can wash away the solid particles on the filter screen when passing through the annular filter frame, and then be intercepted when passing through the multiple filter holes on the filter sleeve. When the filter screen is cleaned, the annular filter frame is reset and fixed by turning the knob again, and the filter screen is used normally. At this time, the filter sleeve can be removed to clean the solid particles in the filter sleeve. The whole cleaning process is simple and convenient to operate, and there is no need to interrupt the discharge process, which greatly improves the work efficiency.

[0014] 2. In this device, when it is necessary to clean the inner wall of the mixing box, the staff rotates the rotating rod through the turning handle, and the rotating rod drives the scraper rod to rotate along the circumferential direction of the inner wall of the mixing box, and uses the scraper rod to scrape off the ink adhered to the inner wall of the mixing box. The scraped ink will enter the arc groove, and due to the setting of the oleophobic layer, it will be more convenient for the ink to flow downward, thereby improving the cleaning and discharge effects, which is worthy of promotion.
