Description

[Technical field]

[0001] The utility model relates to the technical field of transfer films, in particular to the technical field of transfer film ink mixing devices. [Background technology]

[0002] Ink is required for the production of transfer film. Ink is a uniform mixture of colored bodies, binders, fillers, additives and other substances. It can be printed and dried on the printed body. It is a colored, fluid slurry adhesive. Therefore, color, body and drying performance are the three most important properties of ink. There are many types of inks, and their physical properties are also different. Some are very thick and sticky, while others are quite thin. Some use vegetable oil as a binder, while others use resins and solvents or water as a binder. These are all determined by the object of printing, that is, the substrate, the printing method, the type of printing plate and the drying method. Before using the ink for printing, the ink needs to be mixed and blended, because the ink does not have good fluidity. If it is not mixed and blended, the ink will clump and is not easy to print.

[0003] The existing patent CN220257760U discloses a printing ink mixing device, which allows the ink in all parts of the mixing tank to flow by setting scrapers on the bottom and side walls of the mixing tank, so that the ink is mixed evenly. However, since the scrapers are in contact with the inner wall of the mixing tank, they will wear out during long-term use, resulting in poor scraping effect and uneven mixing of the ink.

The mixing cylinder and the circulation cylinder are both vertically arranged circular tubes. The upper middle part of the mixing cylinder and the upper middle part of the circulation cylinder are connected through an upper connecting pipe, and the bottom end of the mixing cylinder and the bottom end of the circulation cylinder are connected through a lower connecting pipe. A liquid outlet pipe with a valve is provided at the bottom of the lower connecting pipe. The top of the circulation pipe is covered with a detachable second sealing cover. The top end cover of the mixing barrel is provided with a detachable first sealing cover, the first sealing cover is provided with a liquid inlet pipe, and a motor is installed on the first sealing cover, the motor is connected to a rotating shaft extending into the interior of the mixing barrel, the rotating shaft and the mixing barrel are located on the same vertical axis, the rotating shaft is composed of a connected screw section and a stirring section, the screw section is located below the stirring section, a plurality of stirring blades are provided on the stirring section, a part of the stirring blades are located above the upper connecting tube, and a part of the stirring blades are located below the upper connecting tube, when the motor drives the rotating shaft to rotate, the screw section lifts the material in the mixing barrel upward.

[0006] Preferably, the inner diameter of the mixing cylinder is larger than the inner diameter of the flow-through cylinder.

[0007] Preferably, the upper connecting pipe is a straight pipe inclined downward from the mixing tube side to the flow tube side, the lower connecting pipe is a curved pipe bent downward, and the liquid outlet pipe is arranged at the lowest point of the lower connecting pipe.

[0008] Preferably, a vent pipe is connected between the mixing cylinder and the circulation cylinder, and the vent pipe is higher than the maximum allowable liquid level of the mixing cylinder and the vent pipe is higher than the maximum allowable liquid level of the circulation cylinder.

[0009] Beneficial effects of the utility model: the utility model forms a rotating shaft by connecting the screw section and the stirring section, and forms a circulation pipeline with the mixing cylinder, the circulation cylinder, the upper connecting pipe and the lower connecting pipe, so that the ink can circulate while being stirred, and it is difficult to have areas where the ink cannot flow, so that the ink is mixed evenly.

[0010] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings.
