Description

Technical Field

[0001] The utility model relates to the field of carbon powder filling, in particular to a carbon powder quantitative filling container for a toner cartridge. Background Art

[0002] Toner, also known as carbon powder, is a powdered substance used in laser printers to fix images on paper. Black toner is composed of binder resin, carbon black, charge control agent, external additives and other ingredients. Color toner also needs to add other color pigments.

[0003] After searching, the existing Chinese patent announcement number is: CN 219552838 U, which provides a quantitative filling container for toner cartridges. The patent rotates the screw sleeve to drive the quantitative disk to move, and the toner filling amount is quantitatively adjusted according to the position of the quantitative disk. It can adapt to different models of toner cartridges for toner filling, and the position of the quantitative disk is marked with scale lines. The quantitative filling of toner is more accurate, effectively avoiding the phenomenon of excessive or insufficient toner.

[0004] Although the above patent can avoid the phenomenon of too much or insufficient toner, the above-mentioned toner quantitative filling container for toner cartridges still has the following problems: when adding toner, the toner needs to smoothly enter the delivery pipe from the feed pipe and then enter under the quantitative plate. Therefore, the tank body cannot store the toner well, and the toner needs to be input from the outside, which makes the device inconvenient to use.

[0005] In view of the above problems, a toner quantitative filling container for toner cartridge is proposed. Utility Model Content

[0032] Rotating the inner rod 16 causes the driving gear 23 to rotate, thereby causing the gear ring 22 and the sealing disc 21 to rotate, so that the second circular hole 20 no longer overlaps with the first circular hole 19. Rotating the inner rod 16 in the opposite direction causes the second circular hole 20 to overlap with the first circular hole 19, and then the carbon powder on the quantitative disk 18 enters the bottom of the quantitative disk 18 through the second circular hole 20 and the first circular hole 19, thereby facilitating the quantitative feeding of carbon powder, preventing carbon powder from overflowing, improving the accuracy of filling carbon powder, reducing the waste of carbon powder, and facilitating the storage of carbon powder, avoiding the need for external injection of carbon powder.

[0033] A sealing cover 4 is fixedly mounted on the top of the tank body 1 .

[0034] The output pipe 2 is provided with a valve 3 .

[0035] The threaded rod 8 is internally slidably connected to a sliding inner rod 5, the upper end of the sliding inner rod 5 slides through the threaded rod 8 and extends to the top of the threaded rod 8, a tension spring 6 is movably sleeved on the surface of the sliding inner rod 5, the upper end of the tension spring 6 is fixedly connected to the sliding inner rod 5, the lower end of the tension spring 6 is fixedly connected to the disc 7, and a knocking ball 17 is fixedly installed on one end of the sliding inner rod 5 extending to the inside of the threaded rod 8, and the knocking ball 17 is in contact with the bottom of the threaded rod 8.

[0036] Pull the sliding inner rod 5, thereby stretching the tension spring 6, so that the sliding inner rod 5 slides outward inside the threaded rod 8, thereby moving the knocking ball 17 upward, and at the same time, the sliding inner rod 5 is no longer pulled, so that the sliding inner rod 5 is reset by the tension of the tension spring 6, so that the knocking ball 17 knocks on the inside of the threaded rod 8, causing the threaded rod 8 and the metering disk 18 to vibrate, thereby preventing carbon powder from accumulating inside the first circular hole 19 and the second circular hole 20, thereby improving the smoothness of material discharge.

A tension spring 15 is movably sleeved on the surface of the polygonal rod 14, and the two ends of the tension spring 15 are respectively fixedly connected to the connecting plate 10 and the side opposite to the rotating inner rod 16. A clamping rod 12 is fixedly installed on the bottom of the connecting plate 10, and two clamping holes 13 are opened on the fixed plate 11. The clamping rod 12 is slidably connected inside the clamping hole 13.

When the second circular hole 20 coincides with the first circular hole 19, the connecting plate 10 is no longer pulled, and the connecting plate 10 is reset, so that the clamping rod 12 enters the inside of another clamping hole 13, and then the rotating inner rod 16 is fixed, which facilitates the fixing of the rotating inner rod 16, thereby preventing the rotating inner rod 16 from rotating and affecting the coincidence of the second circular hole 20 and the connecting plate 10.

[0040] By providing the clamping rod 12 and the two clamping holes 13, it is convenient to position the rotation angle of the rotating inner rod 16, and then it is convenient to make the second circular hole 20 coincide with the first circular hole 19, thereby ensuring the smoothness of material feeding.
