[0028] See also Figure 1-Figure 6 In order to open the feed port 2 during feeding and automatically seal it after feeding is completed, so as to prevent the feed port 2 from opening and causing the internal powder to overflow, and to achieve a dust-proof effect, a sliding groove 11 of a sealing mechanism is provided on the inner wall at the top of the feed port 2, and two groups of movable baffles 6 are slidably arranged inside it, and the tops of the ends close to each other are inclined, and rubber pads 7 are bonded to the end faces close to each other, so as to facilitate the squeezing and opening and closing when the feed pipe 3 moves downward, and to facilitate the subsequent sealing after resetting, so as to ensure the sealing effect and prevent overflow, and the ends of the movable baffles 6 that are away from each other slide out of the sliding groove 11 and extend to the vertical plate 8 with a reset component welded on the outside, and the vertical plate 8 is connected to the outer wall of the feed port 2 by three groups of guide telescopic rods 10. In order to facilitate the subsequent resetting operation, a spring 9 is provided on the outer sleeve of the guide telescopic rod 10.

[0029] See also Figure 1-Figure 6In order to facilitate the mixing and stirring operation and ensure the stability during the rotation process, the wall scraping operation can also be performed to avoid residual adhesion, a motor 12 of a stirring mechanism is fixedly arranged at the bottom of the mixing tank 1, and the output end of the motor 12 penetrates the mixing tank 1 and extends to the inside, where a rotating shaft 13 is fixedly installed through a coupling. The side surface of the rotating shaft 13 is equidistantly equipped with stirring blades 15, which can facilitate the mixing and stirring of the powder inside.

[0030] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0031] In summary, with the aid of the above technical solution of the utility model, when feeding, the feeding pipe 3 moves downward, and its bottom end contacts the rubber pad 7 in the feeding port 2, and deforms. As it continues to move downward and contacts the movable baffle 6, a squeezing force is generated to move them away from each other, and then they slide in the slide groove 11, and the guide telescopic rod 10 and the spring 9 are stretched to store potential energy, and under the action of the potential energy, a thrust is applied to the two movable baffles 6 to approach each other, and then the rubber pad 7 can be used to contact and fit the feeding pipe 3, which is convenient for feeding. After the feeding is completed, it moves up and resets, and at this time, under the action of the potential energy, the two movable baffles 6 are close to each other. In particular, the rubber pad 7 can be used to seal the feed port 2 to prevent the internal powder from escaping from the feed port 2, thereby achieving a good dust prevention effect. When stirring and mixing is required, the motor 12 rotates, driving the rotating shaft 13 and the stirring blades 15 to rotate, so as to stir and mix the internal powder. The auxiliary plate 14 rotates in the annular groove 20 and the ball 19 rotates in the guide groove 21 to ensure stability during rotation. At the same time, the rotation of the rotating shaft 13 can also drive the connecting plate 16 and the fixed plate 17 to rotate, so that the inner wall can be scraped by the scraper 18. After stirring and mixing is completed, the powder can be discharged through the discharge pipe 4.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
