Powder mixing device for production of metal additive capable of preventing friction

Abstract

The invention discloses a powder mixing device for production of a metal additive capable of preventing friction in the technical field of metal additive production equipment. The powder mixing device comprises a base; vertical frames are arranged on the two sides of the top of the base, and a servo motor is arranged on the upper portion of the right side of the vertical frame on the right side; the upper portions of the opposite sides of the two vertical frames are rotationally connected with rotating shafts through bearings; the right end of the rotating shaft on the right side is connected with the power end of the servo motor, the left end of the rotating shaft on the right side is connected with a stirring mechanism, the left end of the stirring mechanism is connected with a fixing frame, and the left end of the fixing frame is connected with the rotating shaft on the left side; and a stirring motor is arranged on the inner wall of the fixing frame, a compensation block can move to the abraded position of a scraping plate after penetrating through a through groove, and thus when the inner wall of a mixing barrel is scraped, the compensation block can scrape the area of the abraded position, and it can be guaranteed that the inner wall of the mixing barrel is comprehensively scraped.

Description

technical field [0001] The invention relates to the technical field of metal additive production equipment, in particular to a powder mixing device for metal additive production that can prevent friction. Background technique [0002] In the production process of metal additives, the powder is mixed by a mixing device. A powder mixing device for the production of metal additives described in Patent No. CN201520101066.X discloses: "The blade 4-2 A soft scraper 4-3 is provided on the top, and the soft scraper 4-3 is a scraper sheet made of rubber. The soft scraper 4-3 is arranged in a dislocation along the blade 4-2, That is to say, all the scrapers 4-3 can form a comprehensive scraping effect on the side wall of the entire mixing pot when rotating, which not only ensures that there is no mixing dead angle inside the mixing pot, but also prevents friction between metals, avoiding Potential safety hazard" and "An electromagnetic clutch 8 is arranged between the mixing pot 1 an...

The soft scraper 4-3 is dislocated along the blade 4-2, that is, all the scrapers 4-3 can form a comprehensive scraping effect on the side wall of the entire mixing pot when rotating, which not only ensures It ensures that there is no mixing dead angle inside the mixing pot, and eliminates the friction between metals, avoiding potential safety hazards" and "an electromagnetic clutch 8 is arranged between the mixing pot body 1 and the main shaft 5; when the electromagnetic clutch 8 is When the power is turned on, the mixing pot body 1 is fixedly connected with the main shaft 5. At this time, the locking of the locking device 10 is released, and the mixing pot body 1 rotates with the main shaft 5, so that the mixing pot body 1 is tilted, and material dumping can be realized. , start the deceleration motor 3, make the mixing pot body 1 tilt and turn over, and pour the mixed powder into the receiving tank 11", firstly, set the scraper made of rubber so that the scraper will not be made of metal materials. The friction of the inner wall of the mixing pot produces a sharp sound of metal friction, which effectively prevents the noise caused by the friction between the metals. However, after a period of use, the rubber scraper is attached to the inner wall of the mixing pot on both sides friction will occur, if attached Figure 4 As shown, the wear on both sides of the end of the scraper attached to the inner wall of the pot cannot scrape the powder on the inner wall of the pot, and then there will be an annular area on the inner wall of the mixing pot that cannot be scraped, resulting in the failure of the device. The use effect is reduced, and the material is poured into the material receiving tank 11 by turning over the mixing pot body. Since the height of the material receiving tank 11 is fixed, when the discharge port of the mixing pot body is located above the material receiving tank 11, the Timely pouring will cause a large amount of powder to scatter. For this reason, we propose a powder mixing device for the production of metal additives that can prevent friction
