Apparatus and method for continuously manufacturing moisture film

摘要

An apparatus and a method for continuously manufacturing moisture films are revealed. At least one loading surface formed by a belt conveyor is used to support and move a lower fabric layer synchronously. During the movement, a top surface of the lower fabric layer is coated with a first fixing solution layer, a gel layer and a second fixing solution layer so as to form a film gradually. Moreover, an upper fabric layer is provided to be attached over the gel layer correspondingly. Then the second fixing solution layer is coated over the upper fabric layer. Thereby a continuous manufacturing of moisture films with or without carriers is completed.

主权项

1. An apparatus for continuously manufacturing moisture films comprising:
at least one belt conveyor, a lower fabric layer, a first fixing solution coating device, a gel coating device, and a second fixing solution coating device; wherein the belt conveyor includes at least one circulating loading surface used as a working platform for forming the moisture film wherein the circulating loading surface includes a flat surface facing upward and moved circularly along a conveying direction from an input end to an output end thereof; the lower fabric layer is disposed on the flat surface of the circulating loading surface and moved synchronously with the loading surface so as to receive various film-forming materials in turn during movement of the lower fabric layer for gradually and continuously forming the moisture film; a first fixing solution layer is coated over the lower fabric layer by the first fixing solution coating device while the lower fabric layer is moved synchronously with the loading surface; the gel coating device is disposed after the first fixing solution coating device; when the first fixing solution layer is coated over the lower fabric layer and moved synchronously with the loading surface to a working range of the gel coating device, a gel layer is coated over the first fixing solution layer by the gel coating device; the second fixing solution coating device is arranged after the gel coating device; after the gel layer is coated over the first fixing solution layer and moved synchronously with the loading surface to a working range of the second fixing solution coating device, a second fixing solution layer is coated over the gel layer by the second fixing solution coating device; a moisture film with a certain thickness is gradually cured and formed over the lower fabric layer due to crosslinking between the first fixing solution layer and the gel layer, and crosslinking between the second fixing solution layer and the gel layer; wherein an upper fabric input device for providing an upper fabric layer is disposed between the gel coating device and the second fixing solution coating device; the upper fabric layer is first attached over the gel layer and then the second fixing solution layer is coated over the upper fabric layer so that crosslinking and curing reactions are carried out between the gel layer and the second fixing solution layer so that the upper fabric layer is contained between the second fixing solution layer and the gel layer to form the moisture film.
