Efficient and precision vacuum powder filling machine

Abstract

The invention discloses an efficient and precision vacuum powder filling machine. The efficient and precision vacuum powder filling machine comprises a carbon powder storage device and a carbon powderfilling device. The carbon powder storage device comprises a supporting frame, a feeding bucket and an upper cover fixedly arranged at the top of the feeding bucket. The feeding bucket is fixedly arranged on the supporting frame, and multiple conical barrels are arranged at the bottom of the feeding bucket in the circumferential direction. A vacuum conveyor communicating with the feeding bucket is fixedly arranged at the top of the upper cover. The carbon powder filling device comprises a supporting rack, a tabletop plate fixedly arranged at the top of the supporting rack and a portal frame fixedly arranged at the top of the tabletop plate. Multiple carbon powder filling units located below a cross beam of the portal frame are fixedly arranged at the top of the tabletop plate, and each carbon powder filling unit comprises a vacuum box, a vacuum generator, a door plate, a weighing device arranged in a closed cavity of the vacuum box, and a rotary air cylinder A fixedly arranged at thetop of the vacuum box. The efficient and precision vacuum powder filling machine has the advantages that the powder filling efficiency is improved, the purity of poured carbon powder is improved, thelabor intensity of workers is reduced, the weighing precision is improved, and the efficient and precision vacuum powder filling machine is suitable for filling powder boxes of different heights.

Description

Technical field [0001] The invention relates to the technical field of powder filling in a powder cartridge for printing, in particular to an efficient and precise vacuum powder filling machine. Background technique [0002] Toner is mainly used in laser printers in printing machinery. Toner is used as a raw material. First, the manufacturer needs to store a certain amount of toner in the powder storage bucket, and then need to transport the toner in the powder storage bucket to the powder bucket of the powder filling mechanism, and the powder filling mechanism then fills the toner cartridge. The toner is finally divided into the toner cartridge, and the toner cartridge can be applied to the printing device. Therefore, the toner filling machine is an important unit for filling powder. [0003] Chinese Patent Publication No. CN 206367624 U discloses a double-head powder filling machine, including a frame 1, a vacuum powder filling system for powder filling 2, a double-head bucket ...

AI Technical Summary

Problems solved by technology

[0004] 1. The funnel 33 connected to the bottom of the double-head barrel 3 is in the shape of a cone, and the toner stored in it is very easy to get stuck in it, that is, the phenomenon of "dead material" occurs, causing the toner to fail to enter the tank powder assembly in sequence 4, which leads to discontinuous powder filling, which reduces the powder filling efficiency, and the follow-up also needs to manually dredge the funnel 33, which is very troublesome

[0005] 2. Although the sliding door 52 can close the powder box 5, there is a gap between the sliding door 52 and the powder box 5, so that during the filling process in the powder box 5, dust in the air is easily mixed in from the gap into the powder box, causing the purity of the toner after filling to decrease, thereby reducing the quality of the toner

[0006] 3. Although the weight of the toner filled in the powder box can be weighed through the weighing pan 51, it is necessary to manually open the sliding door 52 and then read the value on the weighing pan 51, which is very troublesome and increases the labor intensity of the workers , and the value read manually is also inaccurate

[0007] 4. If the height of the powder box to be filled becomes smaller, since the distance between the weighing pan 51 and the powder outlet nozzle 46 cannot be changed, the vertical distance between the powder inlet of the powder box and the powder outlet nozzle 46 becomes larger, And then cause the carbon powder flowing out from the powder outlet nozzle 46 to not all fall in the powder inlet of the powder box, but scattered on the weighing pan, causing the weight of the powder box to be weighed by the weighing pan 51 is inaccurate, and workers need to clean up the scattered The toner on the surface of the weighing pan 51 greatly increases the labor intensity of the workers, so there is an urgent need for a method to improve the efficiency of toner filling, improve the purity of the toner after filling, reduce the labor intensity of the workers, and improve the weighing accuracy.
