Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to a printing machine which is convenient for replacing ink cartridges. Background Art

[0002] Printing presses are used to print books and magazines. Printing presses are also commonly used to produce printed materials such as books and magazines. Printing presses can easily and efficiently produce a large number of cultural publications, and printing presses can be fully or semi-automatically adjusted according to various needs and specifications. Toner, also known as carbon powder, is a powdery substance used in laser printers to form images on paper. Toner needs to be placed in a toner cartridge and installed in a printing press for use.

[0003] According to a disclosed printing press that is easy to replace ink cartridges (publication number: CN214821886U), the above application solves the problem that most existing printing presses need to use tools to disassemble the ink cartridges during the process of replacing ink cartridges, and the disassembly process is cumbersome by setting up a printing press body, a shell, a cover plate, a movable block, a clamping block, a placement plate, an ink cartridge body, a positioning mechanism, a movable plate, a placement slot, a spring, a positioning block, a vertical pipe and a quick-connect connector for use in coordination.

[0004] However, in actual use of the above-mentioned device, the ink cartridge can be easily replaced through the cooperation of the placement plate and the positioning mechanism, but the toner inside the ink cartridge will have the risk of agglomeration if it is not used for a long time. The installed ink cartridge cannot disperse the agglomerated toner, which reduces the effect of ink cartridge replacement. In view of this, we propose a printing press that is easy to replace ink cartridges. Utility Model Content

[0015] 1. The printer that is convenient for replacing ink cartridges can quickly install the ink cartridge body inside the shell through the cooperation of the placement block and the placement groove. The magnetic repulsion between the first magnet block and the second magnet block keeps the telescopic rod and the telescopic spring in a stretched state. The cooperation of the convex ball and the contact block allows the ink cartridge body to squeeze the pressure inside the placement plate. The slider cooperates with the slide groove so that the ink cartridge body has the function of stable movement on the surface of the placement plate. The elastic force of the fixed spring facilitates the reset of the ink cartridge body, so that the ink cartridge body can be quickly replaced while preventing the toner inside from agglomerating and affecting the subsequent printing effect.

[0016] 2. The printer that facilitates ink cartridge replacement is provided with anti-collision strips and anti-slip convex points, so that the ink cartridge body can be prevented from being damaged by the placement plate when the ink cartridge body moves horizontally, thereby improving the stability of the ink cartridge body in preventing agglomeration.
