The electric signal is generated by the voltage, and the electric signal receives the signal through the controller, and makes a group of helical coils on the outside of each piezoelectric sheet energized. The magnetic force generated by the helical coil is much greater than that of the magnetic bar, and it is the same as the magnetic strip. Therefore, , the magnetic strip is extruded from the extrusion groove by the repulsive force, so that it abuts on both sides of the blank material, thereby forming a separation and storage effect on the placed blank material.

2. Since the triggered magnetic strip drives the elastic film to form supports on both sides of the blank, it can store and separate blanks of different thicknesses, improving the adaptability to blanks of different thicknesses; at the same time , the magnetic field generated by the energized helical coil hardens the magnetorheological fluid at the corresponding position, thus forming a support for the blank material. According to the thickness of the blank material, its weight is also different. When the weight is large, the piezoelectric sheet The deformation current increases, so that the current of the helical coil becomes larger, so that the hardness of the magnetorheological fluid at the corresponding position is increased, thereby improving the adaptability to blank materials of different qualities.

3. In the process of taking the blank material, take out the blank material that needs to be taken out by hand. At this time, the electric signals of the corresponding multiple piezoelectric sheets at the bottom disappear, and the controller stops supplying power to the corresponding spiral coil. The magnetism of the collar disappears, so that the magnetorheological fluid returns to its fluid state, and the magnetic attraction force of the magnetic rod makes the magnetic strip at the taking position re-enter the liquid tank, and it is always held in a fixed position with the blank material placed in the position. Compared with extracting a blank from the accumulated blank, it saves time and effort and does not need to sort out the remaining blanks.

4. When storing multiple blanks, each blank triggers a piezoelectric film in a local area, thereby achieving separate separation and storage, and finally forms a fully independent storage of multiple documents. Therefore, it can meet the requirements for separation There are many areas or even completely separate storage requirements, and at the same time, the mutual accumulation of blank materials is effectively avoided, which greatly improves the flexibility and convenience of storing and taking blank materials.
