Problems solved by technology

However, because the thread of the barrel is a continuous helical thread, the carbon powder cannot be fully mixed with the air during operation, which will lead to unsmooth feeding of the powder, a reduction in the amount of powder, and the problem of large residual powder in the barrel.
In addition, the existing toner supplier is installed with a spring connection. After the toner cartridge is installed in the machine, the spring is under pressure and acts between the machine and the toner cartridge all the time, increasing the rotational resistance of the machine and affecting the final use of the machine. life
In addition, the structure of the toner outlet of the toner supply is complicated, and there is a problem that the toner can penetrate into the gap, resulting in a large installation resistance

Abstract

The invention discloses an improved toner barrel which structurally comprises a barrel body, wherein a toner conveying piece is arranged inside the barrel body; a top cover is arranged on the top of the barrel body; a T-shaped spiral groove is formed in the surface of the barrel body; an L-shaped thread and at least one withdrawing-stopping groove are formed in the bottom of the top cover; a toner outlet is formed in the upper part of the top cover; a toner outlet sealing ring is arranged on the outer side of the toner outlet in a sliding manner; a second sealing ring and a third sealing ring are arranged at the upper part of the toner outlet sealing ring; a first sealing ring and a fourth sealing ring are further arranged on the outer side of the toner outlet. By adopting the improved toner barrel, the defects in the prior art can be improved, by changing the structure of the thread and omitting the structure of double-piece sponges and springs between the toner outlet and the toner outlet sealing ring, the sliding resistance is reduced, and after the toner outlet is opened, no extra pressure is caused between the toner barrel and a machine, so that the toner barrel can rotate smoothly.

Description

Technical field [0001] The invention relates to a printer consumable, in particular to an improved toner cartridge. Background technique [0002] In imaging equipment such as printers, toner cartridges are used to supply toner for imaging. Chinese patent CN201107552Y discloses a toner supply. However, because the thread of the barrel is a continuous spiral thread, the carbon powder cannot be fully mixed with air during operation, which will cause the powder to be unsmoothed and the amount of powder to be reduced, and there is a problem of large residual powder in the barrel. In addition, the existing toner supply adopts spring connection and installation. After the toner cartridge is installed in the machine, the spring is compressed and acts on the machine and the toner cartridge all the time, which increases the rotation resistance of the machine and affects the ultimate use of the machine. life. In addition, the structure of the powder outlet of the toner supply is complica...
