Detailed Description
An internal transmission mechanism for opening and closing a discharge port comprises a feeding screw rod 2 positioned in a material box 1 (which can be in a box body, a hopper and the like), wherein a valve sleeve driving thread 3 is arranged at the front end of the feeding screw rod, a valve body 4 is fixedly arranged at the discharge port of the material box through a nut 10, a valve sleeve 5 is sleeved on the valve body, a transmission member 6 is fixedly arranged on the valve sleeve, the transmission member is positioned in the valve sleeve driving thread, and the transmission member drives the valve sleeve to move back and forth through the rotation of the valve sleeve driving thread on the feeding screw rod, so that the opening and closing of a discharge port 9 on the.
The transmission part is a transmission pin, an elastic positioning bead, a positioning sheet or a positioning rod. The end part of the feeding screw rod is provided with a limiting device with a limiting function. The limiting device is a clamp spring or a clamping protrusion 7. A push spring 8 can be further arranged between the transmission part and the valve sleeve to enhance the moving performance of the valve sleeve.
When in work: the output shaft of the driving motor is used for pushing the materials to the discharge hole through outputting power to the internal feeding screw rod, the discharge hole valve sleeve moves in parallel while rotating, and the discharge hole is opened to form discharge. After the discharging is finished, the driving motor rotates reversely, and the feeding screw drives the discharge port valve sleeve to move in parallel to close the discharge port.
