Start the No. 2 motor (30), the No. 2 motor (30) makes the eccentric wheel (29) rotate, and the eccentric wheel (29) contacts the bottom of the inner side of the transmission frame (28), so that the transmission frame (28) moves down, and the transmission The frame (28) moves the conical block (42) downward through the vertical rod (3), and the material in the feeding pipe (38) is no longer blocked by the conical block (42), so it falls onto the conical block (42). , then falls on the support material plate (7), flows out from the discharge port (16) after passing through the support material plate (7), and flows out of the lower material box (1) through the guidance of the material guide plate (19), and the eccentric wheel (29) Continue to rotate, the eccentric wheel (29) contacts the top of the inner wall of the transmission frame (28), so that the transmission frame (28) moves upward, and the transmission frame (28) makes the cone block (42) move toward the vertical rod (3). When moving upward, the conical block (42) blocks the feeding tube (38), and repeating the above steps, the quantitative feeding can be performed multiple times; S4. When the transmission frame (28) moves down, it also drives the No. 2 cross block (27) to move down, the No. 2 cross block (27) makes the No. 1 cross block (25) move down, and the No. 25) Move the T-bar (22) down, the T-bar (22) compresses the No. 1 spring (21), when the No. 2 cross block (27) moves up, the No. 1 spring (21) resets to make the T The shaped rod (22) moves upward, the T-shaped rod (22) makes the percussion ball (26) move upward, and knocks the supporting material plate (7) to make it vibrate, so as to avoid the material remaining on the supporting material plate (7). )superior; S5. When the material needs to be weighed, the material door (18) is lowered through the electric telescopic rod (15) to block the discharge port (16), and the No. 2 motor (30) is started to lower the transmission frame (28), so that the The conical block (42) is not blocking the feeding tube (38), the material falls on the supporting material plate (7), and the transmission frame (28) also moves the T-bar (22) downward when the transmission frame (28) descends, so that the ball is hit (26) It does not contact the support material plate (7), and will not affect the detection of the pressure sensor (5). The material exerts force on the pressure sensor (5) through the support material plate (7) and the connecting rod (6). According to The reading of the pressure sensor (5) can be used to weigh the material. When the required weight is reached, the transmission frame (28) is moved upward, and the conical block (42) blocks the feeding tube (38), and then starts the electric expansion and contraction. The rod (15) moves the material door (18) upward, and the material flows out from the material outlet (16).
