And so that the receiving belt 90 between the driven roller 32 and the steering roller 33 is positioned between the electrode plate 12 and the liquid ejection tray 22. When the electrode plate 12 and the liquid ejecting tray 22 are energized, an electric field can be generated between the electrode plate 12 and the liquid ejecting tray 22, so that the liquid on the head 21 can be ejected onto the receiving belt 90 under the action of the electric field. Here, the spray head 21 may also be provided as a conductive member, the spray head 21 may also be provided as an insulating member, another electrode plate 12 may also be provided on the side of the spray tray 22 facing away from the receiving tape 90, and so on.

The electrode plate 12 may be plate-shaped, and the electrode plate 12 may be provided with a plurality of through holes, or the electrode plate 12 may be mesh-shaped. It will be appreciated that if the electric field strength between the electrode plate 12 and the liquid spray tray 22 is too high, it is easy to cause the liquid on the spray head 21 to spray toward the receiving belt 90, i.e., it is easy to cause the liquid on the spray head 21 to spray toward the receiving belt 90 without forming into bead-like droplets, resulting in less liquid spraying toward the receiving belt 90 and less screen forming. Moreover, the receiving belt 90 is continuously moved, and when the next droplet is sprayed to the receiving belt 90, the screen formed at the previous time is far away, which easily causes the poor quality of the formed screen.

When the fan is arranged close to the driving roller 31, the fan can blow the receiving belt 90 in the drying area as large as possible, so that the drying effect is improved. Wherein, the air blown out by the fan can be cold air or hot air. Of course, in other embodiments, the blowing direction of the fan may be the same as the moving direction of the receiving belt 90 from the steering roller 33 to the driving roller 31, or the outlet of the fan may be directed toward the receiving belt 90.

This reduces the likelihood of liquid spraying or dripping onto the receptor web 90 during non-operational conditions. In addition, when the liquid is ejected from the ejection head 21 but not all of the liquid is ejected toward the receiving belt 90, the liquid can be made to slide down the ejection head 21 onto the liquid ejection tray 22, which facilitates collection and recovery, and avoids waste and environmental pollution. Of course, in other embodiments, the receiving belt 90 in the receiving zone and the receiving belt 90 in the drying zone may be arranged in a horizontal direction, or in a direction oblique to the horizontal direction.

In one embodiment, the number of the liquid ejecting members 20 is plural, and the plural liquid ejecting members 20 are arranged at intervals along the distribution direction of the driven roller 32 and the steering roller 33. Since the droplets are ejected at a high speed by the electric field, when the micro-jets are deposited on the receiving belt 90, the formed screen is thin, and the screen may be unevenly distributed and the forming quality is poor. By arranging the plurality of liquid spraying parts 20, after the previous liquid spraying part 20 forms a silk screen on the receiving belt 90, the next liquid spraying part 20 can cover the formed silk screen on the silk screen formed by the previous liquid spraying part 20, so that a plurality of layers of silk screens can be formed by the plurality of liquid spraying parts 20, the thickness of the finally formed silk screen can be increased, and the finally formed silk screen can be ensured to have better quality.

And the heater 80 is arranged between two adjacent liquid spraying parts 20, so that the silk screen formed by the former liquid spraying part 20 can be primarily dried, the silk screen formed by the latter liquid spraying part 20 can be better covered on the former layer of silk screen, and the quality of the silk screen is improved. The heater 80 may be an infrared heater 80, or may be a resistance wire heating or the like.

In one embodiment, the high voltage electrostatic spinning machine further comprises a second lifting mechanism 50 and a liquid reservoir 70, wherein the second lifting mechanism 50 is connected with the liquid reservoir so that the liquid reservoir can move in the up-and-down direction.
