Problems solved by technology

This method can level the powder falling into the material box to a certain extent, but it takes a lot of time and different operators will get uneven and uneven powder when scraping the powder. When large-scale processing of powder is carried out, this method is difficult to meet the requirements of rapid processing, thus restricting the development of related processing processes

Embodiment 1

[0036] Such as figure 1 As shown, a powder scraping device includes a control system, a scraping system and a platform system, wherein:

[0037] Described platform system comprises support 18, platform 19 and feed box 20, and described support 18 is fixed on described platform 19, is mainly used in supporting described scraping system; Described feed box 20 is located on described platform 19 and It is located below the scraper 16 (directly below in this embodiment) for collecting powder.

[0038] The scraping system includes a Y-direction motor 4, a first coupling 5, a screw 6, a nut 7, a slider 8, a rotating motor seat 9, a rotating motor 10, a second coupling 11, an output shaft 12, an electromagnet 13. Suction plate 14, scraper seat 15, scraper 16 and pull nail 17, the Y-direction motor 4 is connected to the screw 6 through the first coupling 5, the screw 6 is connected to the slider 8 through the nut 7, and the slider The other side of the block 8 is connected to the ro...

Embodiment 2

[0047] A method for controlling powder leveling, using the powder leveling device described in Embodiment 1, the flow chart of which is as follows figure 2 shown. The specific description is as follows:

[0048] 1) The electromagnet 13 is de-energized, the scraper 16 is put down, and the ranging sensor 3 measures the distance;

[0049] 2) Determine whether the scraper seat 15 is at the initial position, if so, go to step 3), otherwise adjust the scraper seat 15 so that the scraper seat 15 is at the initial position, go to step 2);

[0050] 3) Rotate the Y-direction motor 4 to move the scraper seat 15 downward, and at the same time, the rotating motor 10 rotates to drive the scraper 16 to rotate;

[0051] 4) Judging whether the scraper seat 15 has reached the first designated position, if yes, then the Y-direction motor 4 stops rotating, after a period of delay, enter step 5), if not, turn to step 3);

[0052] 5) Rotate the motor 4 in the Y direction to move the scraper sea...

Abstract

The invention discloses a pulverulent body striking-off device and a control method thereof. The pulverulent body striking-off device comprises a control system, a striking-off system and a platform system, wherein the platform system comprises a bracket, a platform and a material box; the striking-off system comprises a Y-oriented motor, a first coupler, a screw rod, a nut, a sliding block, an electric rotating motor seat, an electric rotating motor, a second coupler, an output shaft, an electric magnet, a pulling-in disk, a scraper seat, a scraper and a pop-rivet; and the control system comprises a ranging sensor, a multi-functional board and a computer. The invention processes the distance data from the scraper to the bottom of the material box, which is measured by the ranging sensor and acquired by the multifunctional board, by the computer and then adjusts the rotation of the Y-oriented motor and the electric rotating motor based on a processing result so as to ensure that the scraper and the scraper seat respectively complete the scraping and the pressing actions on the pulverulent body inside the material box, which can carry out fast, uniform and even striking-off on the pulverulent body dropping in the material box.

Description

technical field [0001] The invention belongs to the technical field of powder processing and its control, and in particular relates to a powder scraping device and a control method thereof. Background technique [0002] Powder processing equipment is used in pharmaceutical and military industries and other fields. How to quickly and evenly scrape the powder falling into the material box, so that the powder can be evenly spread in the material box, is of great importance for ensuring the quality of medicines and military products. At present, the method of scraping the powder falling into the material box is generally to use manual scraping. This method can level the powder falling into the material box to a certain extent, but it takes a lot of time and different operators will get uneven and uneven powder when scraping the powder. When the powder is processed on a large scale, this method is difficult to meet the requirements of rapid processing, thus restricting the deve...
