Problems solved by technology

This design idea will result in many processing steps: first, it is necessary to continuously add a small amount of powder into the scale until the powder in the scale just reaches or slightly exceeds the predetermined weight (the excess weight must be within an acceptable error range), Then fill the powder in the scale into the packaging container, then compact it, and finally package it
[0003] Due to the many processing steps in the whole processing process, it is difficult to improve the processing efficiency, and because the speed of the production line is determined by the slowest link on the production line, the processing speed of the above-mentioned powder filling mechanism cannot be increased, which will cause the entire production line The production efficiency is low, the production cost is high, and it cannot meet the needs of large-scale industrial production

Embodiment 1

[0025] Such as Figure 1-5 As shown, the high-precision powder filling mechanism in this embodiment includes a support frame 1 and 12 high-precision filling devices, and the high-precision filling device includes a filling head 2, a blanking trough 3, a mold 4, Screw 5, first motor 6, hopper 7, discharge pipe 8, feed rod and feed rod drive device, the hopper 7, filling head 2, discharge pipe 8 are respectively installed on the support frame 1, the The top of the discharge pipe 8 is communicated with the outlet at the bottom of the hopper 7, the screw 5 is located in the discharge pipe 8, the first motor 6 is installed on the outer opening of the discharge pipe 8, and the first motor 6 is connected with the screw 5, The filling head 2 is located below the inner opening of the discharge pipe 8, the top of the blanking chute 3 is connected to the inner opening of the discharge pipe 8, the bottom end of the blanking chute 3 is connected to the filling head 2, and the filling head ...

Embodiment 2

[0043] The difference between the high-precision powder filling mechanism in this embodiment and Embodiment 1 is:

[0044] A transition gear is added between the driving gear 10 and the adjacent driven gear 11 , and a transition gear is also added between the driven gear 11 and the adjacent driven gear 11 . This design makes the feed rods all turn in the same direction: counterclockwise. Therefore, the feeding rods can adopt the same structure without using the reverse feeding rod 13, which can effectively reduce the types of components and reduce the cost of production and maintenance.

Embodiment 3

[0046] The difference between the high-precision powder filling mechanism in this embodiment and Embodiment 1 is:

[0047] The number of the high-precision filling device is one. Therefore, the driving gear 10, the driven gear 11, the reverse scraper bar 21, etc. all need not be used.

Abstract

Disclosed is a high-precision powder filling structure. The high-precision powder filling structure comprises a support frame and at least one high-precision filling devices. Every high-precision filling device comprises a filling nozzle, a charging tank, a mold, a screw, a motor, a hopper and a discharging pipe. The high-precision powder filling structure is characterized in that the high-precision filling device also comprises a feeding rod and a feeding rod driving device, wherein he feeding rod driving device is mounted on the support frame, the top end of the feeding rod is connected with the feeding rod driving device, the bottom end of the feeding rod is provided with at least two scraping rods, and scraping spaces are formed between every two neighboring scraping rods. Compared with the prior art, the high-precision powder filling structure has the advantages that, due to the face that a servo motor maintains the pressure of powder at the outlet of the discharging pipe through the screw, the density uniformity of the powder can be well maintained; meanwhile, the feeding rod scrapes powder at the outlet of the discharging pipe and accordingly can rapidly scrape off high-weight-precision powder. The high-precision powder filling structure is simple in structure, high in production efficiency, low in cost and capable meeting the requirements on industrialized mass production.

Description

technical field [0001] The invention relates to a powder material filling mechanism, in particular to a high-precision powder material filling mechanism with high processing speed and high weight accuracy of each filling powder material. Background technique [0002] The traditional powder filling mechanism uses a weighing tool to accurately weigh the powder and then fill it. This design idea will result in many processing steps: first, it is necessary to continuously add a small amount of powder into the scale until the powder in the scale just reaches or slightly exceeds the predetermined weight (the excess weight must be within an acceptable error range), Then fill the powder in the scale into the packaging container, then compact it, and finally package it. [0003] Due to the many processing steps in the whole processing process, it is difficult to improve the processing efficiency, and because the speed of the production line is determined by the slowest link on the p...
