Description

Technical Field

[0001] This utility model relates to the technical field of powder shaker accessories, and in particular to a powder distribution roller that reduces powder melting and loss. Background Technology

[0002] The toner distribution chamber is the functional part inside the toner dispenser that distributes the toner onto the printing media. It is generally located at the feed end of the dispenser to facilitate the distribution of toner onto the printing media during toner feeding. The toner distribution roller is the core component of the toner dispenser, located at the bottom output end. It rotates synchronously and continuously, ensuring that the toner is distributed onto the printing media at a uniform speed. Existing toner distribution rollers have several rigid partitions distributed around their circumference to evenly distribute the toner guided to the bottom of the dispenser into equal-sized spaces. The continuous rotation of the roller allows the toner at the bottom output end of the dispenser to be constantly agitated, ensuring that the toner in each evenly distributed space has an equal chance of being discharged from the bottom output end. This effectively prevents toner blockage and ensures the stability of the toner output speed. However, the friction between the rigid partitions and the inner wall of the bottom output end of the dispenser can easily generate a large amount of heat, causing the toner entering the evenly distributed spaces to melt and adhere to the bottom output end of the dispenser. The toner that adheres to the bottom output end of the toner cartridge can no longer be distributed onto the printing media, resulting in material waste. It also gnaws at the rigid partition plate, hindering the normal rotation of the toner roller. Utility Model Content

[0016] Example 1: See Figure 1-8A powder-distributing roller for reducing powder melting loss is laterally positioned at the bottom output end 01 of a powder-distributing box 00. The bottom output end 01 of the powder-distributing box 00 has horizontally distributed powder outlet holes 011.
