[0030] Through the settings of the separation filter 3, the straight hole filter sheet structure 4, the fixator 5, the power motor 6, the rotating shaft 7, the connecting block 8, the collision ball 9, the support rotating shaft 10, the first support plate 11, the support spring 12, the first fixing plate 13, and the collision block 14 of the pneumatic dry powder feeding machine for a straight hole filter sheet, when feeding dry powder, sundries therein can be blocked and separated to prevent affecting the dry powder processing. Moreover, through the movement of the first fixing plate 13, the collision block 14 can collide with the straight hole filter sheet structure 4 to vibrate it, and the blocked sundries can be shaken off, so that the dry powder feeding efficiency is high; through the settings of the fixing motor 16, the fixing shaft 17, the fixing rod 18, the first scraper 19, the stirring rod 20, and the second scraper 21, after the dry powder is fed, the dry powder can be stirred to prevent the dry powder from accumulating, coagulating, and caking.

[0037] Working principle: When in use, place the separation filter 3 on the dry powder, start the pneumatic vacuum pump 15 to generate negative pressure inside the feeding tank 1, suck the dry powder into the feeding tank 1 through the feed pipe 2 for feeding the dry powder. The sundries in the dry powder are filtered and blocked by the straight-hole filter plate structure 4, so that there are fewer impurities in the dry powder. Start the power motor 6, and the rotating shaft 7 drives the collision ball 9 to rotate through the connecting block 8 and apply force to the first support plate 11 to push it. As a result, the first fixing plate 13 drives the collision block 14 to move synchronously through the support rotating shaft 10, collide with the straight-hole filter plate structure 4 to vibrate it, and shake off the impurities in the filter holes, improving the efficiency of feeding the dry powder. Moreover, the fixed motor 16 raises the fixed shaft 17, and the fixed rod 18 respectively makes the first scraper 19, the stirring rod 20 and the second scraper 21 rotate to stir the dry powder, and at the same time scrape the dry powder adhered to the inner wall of the feeding tank 1 to prevent the dry powder from accumulating, condensing and solidifying in the feeding tank 1.
