Description

Technical Field

[0001] The utility model relates to the technical field of material printing, and more specifically to a printing device with fast color switching. Background Art

[0002] Printing is a process of transferring the graphic information on the original to the substrate using a printing plate or other means. Printing transfers the ink from the printing plate to the substrate through processes such as plate making, inking, and pressurization, thereby achieving the reproduction of the image and text. The printing device is a mechanical device that transfers the ink of the image and text on the printing plate to paper or other printing materials. It achieves the reproduction of the image and text by evenly applying the ink on the printing plate and transferring the ink to the printing material under the action of pressure. The printing device consists of a printing part, a plate mounting part, an inking part, and auxiliary devices. Its work is mainly divided into four parts: plate making, inking, pressurized transfer, and drying and curing. The steps are as follows: the graphic information is made on the printing plate by computer plate making or manual plate making, and then the ink or toner is applied to the surface of the graphic through a roller or a nozzle. Under the action of pressure, the ink is transferred from the printing plate or rubber cloth to the printing material, and the ink is firmly attached to the printing material after heating or exposure curing. The existing mechanical printing device applies the ink to the printing plate by replacing the ink cartridge or installing multiple ink cartridges. The process of replacing the ink cartridge is cumbersome and wastes a lot of time. The method of installing multiple ink cartridges will make the mechanical structure bloated, complicated and difficult to operate, and the same ink cartridge will fade the color and the graphic will not be visible after multiple printings.

The rotation of the motor shaft 3014 drives the extrusion turntable 3015 to rotate. During the rotation of the extrusion turntable 3015, the motor shaft 3014 will press the pressing pestle 3023 downward, and the pressing pestle 3023 squeezes the air pipe 3 3021, the air in the air tube 3021 will squeeze the same-position pestle 3024 at the same time, which means that the same-position pestle 3024 moves downward, and the same-position pestle 3024 moves downward to push the rubbing plate 3026 and squeeze the reset member 3025 at the same time. The rubbing plate 3026 is pushed down to contact the object to complete the rubbing. When the motor shaft 3014 squeezes the pressing pestle 3023, the same-position pestle 3024 moves upward under the action of the reset member 3025 to reversely squeeze the air in the air tube 3021. The air in the air tube 3021 pushes the pressing pestle 3023 to move up and reset, and the cycle is repeated. The rotating shaft 205 applies color to the rubbing plate 3026 every time it makes a circle. This process avoids In order to solve the problem of insufficient ink and poor display of images and texts after multiple rubbings on the printing plate, the required ink is stored in the ink cartridge 3034, and inks of different colors are added to the ink cartridge 3034. The ink-immersed wet cotton 3035 is always immersed in ink to color the coloring brush 206. The user rotates the handle rotating disk 3037. Different handles in the handle rotating disk 3037 represent inks of different colors. The user rotates the corresponding handle to the top of the handle rotating disk 3037 for the ink needed. At the same time, the linkage chain 3036 drives the connecting block 3033 to rotate. The three ink cartridges 3034 are in the same frequency as the three handle rotating disks 3037. This process can achieve rapid switching of printing colors by rotating the rotating disk.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
