Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

Wherein the showings are for the purpose of illustration only and are shown by way of illustration only and not in actual form, and are not to be construed as limiting the present patent; for a better understanding of the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

The same or similar reference numerals in the drawings of the embodiments of the present invention correspond to the same or similar parts; in the description of the present invention, it should be understood that if the terms "upper", "lower", "left", "right", "inner", "outer", etc. are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, it is only for convenience of description and simplification of description, but it is not indicated or implied that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and therefore, the terms describing the positional relationship in the drawings are used only for illustrative purposes and are not to be construed as limiting the present patent, and the specific meaning of the terms will be understood by those skilled in the art according to the specific circumstances.

In the description of the present invention, unless otherwise explicitly specified or limited, the term "connected" or the like, if appearing to indicate a connection relationship between the components, is to be understood broadly, for example, as being either a fixed connection, a detachable connection, or an integral part; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or may be connected through one or more other components or may be in an interactive relationship with one another. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in the figure, the utility model discloses a awl is fought 1 and is fixed at the conveying motor 2 that the awl was fought 1 top, and the conveyer pipe 3 is connected to the lower extreme that the awl was fought 1, and conveying motor 2's output shaft 4 is fought 1 interior through adapter sleeve 5 connection feeding screw rod 6 in the awl, and fixed flitch 7 of scraping is gone up to adapter sleeve 5, scrapes flitch 7 and awl and fights 1 inside wall phase-match, adapter sleeve 5, feeding screw rod 6 and scrape flitch 7 synchronous revolution. The feeding screw 6 and the scraping plate 7 adopt the same power source to convey the motor 2, so that the structure is simplified and the space is saved. Scrape flitch 7 and play broken bridge effect, prevent that the material from taking a bridge. The feed opening 9 is fixed to the lower extreme of awl fill 1, and feed opening 9 passes through clamp 8 and connects conveyer pipe 3, increases the leakproofness, and easily dismouting. The diameter of the feeding screw 6 is matched with the inner diameter of the feed opening 9. A tuning fork level switch 10 is arranged on the cone hopper 1 to monitor the material height in the cone hopper 1, and when the material is lower than a certain height, a user is prompted to add the material. The cone hopper 1 is fixed on the rotary support column 11, the rotary support column 11 is movably inserted on the fixed pipe column 12, the movable insertion part is provided with a tetrafluoro shaft sleeve 13, and the tetrafluoro shaft sleeve 13 is simple in structure, so that the powder supply mechanism is guaranteed to rotate naturally and is not blocked. The connecting sleeve 5 is externally provided with a dustproof end cover 14 to prevent the material dust from influencing the work of the conveying motor 2. Under the condition that materials exist in the conical hopper 1, the feeding screw 6 rotates anticlockwise, and the spiral is in a rising state; the material is lifted spirally and generates downward force to the material, and the material on the feeding screw 6 moves downwards, enters the feed opening 9 and the conveying pipe 3 and falls into the cylinder body; therefore, under the condition that the rotating speed of the feeding screw rod 6 is fixed, the material entering the cylinder body is not changed every time, and the effect of uniform-speed blanking is achieved. The above-mentioned embodiment is only to describe the preferred embodiment of the powder conveying mechanism of the present invention, and not to limit the concept and scope of the present invention, and without departing from the present invention, the skilled person in the art will be right the various shape modifications and improvements made by the technical solution of the present invention all fall into the protection scope of the powder conveying mechanism of the present invention.
