[0018] Compared with the prior art, the utility model has the advantages that:

[0019] This precise material feeding device uses a feeding baffle in conjunction with a hinged arm, a threaded plate, a threaded rod, and a motor. The rotation of the motor drives the threaded rod to rotate, which in turn drives the threaded plate to move. The hinged arm, through its hinged action, drives the mounting plate to move the feeding baffle. The contact plate and the contact switch reverse the motor, thus continuously opening and closing the feeding baffle. This allows for intermittent material feeding, effectively preventing the problem of material accumulation when added all at once. Furthermore, the position of the contact switch can be adjusted by sliding the guide plate up and down, allowing for adaptive adjustment of the opening distance of the feeding baffle and the amount of material fed each time, thus improving its versatility.

[0020] This precise material feeding device uses a motor in conjunction with a rotating shaft and a toggle plate. The motor drives the rotating shaft to rotate the toggle plate, and with the help of a contact rod and a contact switch, the motor can rotate in both directions. This causes the toggle plate to swing back and forth continuously, which can disperse the material and make the material more dispersed during feeding. Attached Figure Description
