At the same time, the motor is turned on. After the motor is turned on, the output shaft of the motor drives the connecting rod to rotate. When the connecting rod rotates, the connecting rod drives the scraper plate to rotate. When the scraper plate rotates, the scraper plate scrapes the surface of the filter plate. When the scraper plate scrapes, the scraper plate squeezes the side of the convex rod. After the convex rod is subjected to the extrusion force from the scraper plate, when the convex rod starts to move downward, the convex rod stretches the length of the spring. At the same time, when the convex rod moves down, the bottom stabilizing plate is also driven to move downward. When the stabilizing plate moves downward, the stabilizing plate drives the knocking rod 1 above to move downward. Then, when the scraper plate continues to rotate with the rotation of the connecting rod, the extrusion force of the scraper plate on the convex rod 1 disappears. The protruding rod 1 starts to move upward through the elastic force of the spring 1 above the bottom stabilizing plate. When the protruding rod 1 moves upward, the protruding rod 1 drives the bottom stabilizing plate to move upward as well. When the stabilizing plate moves upward, the stabilizing plate drives the knocking rod 1 to move upward as well.

There are two connecting short plates and cams, and they are arranged in a circular array on the bottom of the motor. One end of the cam is close to the top of the connecting plate. When the filter material falls downward, the filter material falls to the top of the motor. After the motor is subjected to the gravity from the filter material, the motor starts to move downward. When the motor moves downward, the motor squeezes the spring two below. After the spring two is subjected to the extrusion force from the motor, the spring two begins to contract. Then, when the motor moves downward, the motor drives the connecting plate to move downward. When the connecting plate When the cam is moved upward, the cam drives the connecting short plate and the feeding plate to move upward as well. When the cam is moved upward, the cam drives the connecting short plate and the feeding plate to move upward as well.

Then, the cam second starts to move downward through the elastic force of the spring two under the feeding plate. When the cam second moves downward, the cam second drives the upper connecting short plate and the feeding plate to start moving downward, thereby making the feeding plate repeatedly move up and down, thereby achieving the effect of batch feeding, which can ensure that the quality and quantity of each feeding are controllable, help to ensure the stability of the quality of the outflowing liquid, and improve the quality and consistency of the product.

When the extrusion block moves downward, the inclined surface of the extrusion block squeezes the fixed long plate below. After the fixed long plate is subjected to the extrusion force from the extrusion block, the fixed long plate starts to move inward. When the fixed When the long board moves inward, the fixed long board stretches the spring three on the side. At the same time, the fixed long board moves inward, driving the pushing block on the side to move inward as well.
