A vacuum feeder is a conveying device that uses vacuum suction to transport granular and powdered materials. It is widely used in the production and research fields of pharmaceuticals, food, chemicals, ceramics, feed, pigments, dyes, and agricultural products. The use of vacuum conveyors can significantly reduce dust pollution in workshops, enhance cleanliness, and greatly save labor, reduce pollution, and be safe and reliable.

The composition of the suction feeder:

1: Vacuum generator or vacuum pump.

2: Filtering device

3: Suction port

4: Silo

5: Reverse-blowing can

6: Discharge valve

7: PLC control system

Factors affecting the operation of the feeding machine

Different positioning methods have different influencing factors. When positioning a mechanical stop block, the positioning accuracy is related to factors such as the stiffness of the stop block and the speed at which the stop block is touched.

2. Positioning speed has a significant impact on positioning accuracy. This is because when the positioning speed is different, the energy that must be dissipated from the moving parts is also different. Generally, to reduce positioning errors, the positioning speed should be reasonably controlled, such as enhancing the buffering performance and efficiency of the buffer device, and controlling the drive system to slow down the moving parts in a timely manner.

3. The manufacturing accuracy and installation speed regulation accuracy of the precision manipulator have a direct impact on the positioning accuracy.

4. Weight of moving Parts The weight of moving parts includes the weight of the mechanical hand itself and the weight of the object being grasped. The change in the weight of moving parts has a significant impact on positioning accuracy. Generally, when the weight of a moving part increases, the positioning accuracy decreases. Therefore, when designing, it is necessary not only to reduce the weight of the moving parts themselves, but also to take into account the impact of changes in the grip weight during operation.

The position control accuracy of switch control, electro-hydraulic proportional control and servo control in the control system is not the same. This is not only because the precision and sensitivity of various control components are different, but also related to the presence or absence of position feedback devices.
