Continuous film-forming manufacturing equipment and film-forming method for wet adhesive film

Abstract

The invention relates to a continuous film-forming manufacturing device of a wet-type colloidal film and a film-forming method thereof. According to the invention, at least one cyclic-type conveyer belt is employed to form at least one bearing surface which moves cyclically along a preset conveying direction, wherein a lower fabric layer is supported on the surface of the bearing surface and can be moved in a synchronously conveying manner. In the front of or above the bearing surface, following parts are arranged successively: a first fixing liquid coating apparatus used for coating the lower fabric layer with a first fixing liquid layer, a colloid coating apparatus used for coating the first fixing liquid layer with a colloid layer so that a crosslinking and cure-shaping effect from bottom to top is carried out; and a second fixing liquid coating apparatus used for coating the colloid layer with a second fixing liquid layer so that a crosslinking and cure-shaping effect from top to bottom is carried out, thereby gradually forming a colloidal film in a proper thickness on the upper surface of the lower fabric layer during the process of synchronously conveying movement of the upper fabric layer, and further forming the continuous film-forming process of the wet-type colloidal film.

AI Technical Summary

Problems solved by technology

[0007] One, the wet-type adhesive film is a soft and thin colloidal film. For the convenience of the process or the convenience of cutting (such as cutting into the shape of a mask), the inventor of this case first discovered and thought that if the wet-type adhesive film can use a It must be the most beneficial for the manufacture of wet adhesive films to carry out transportation with a flat bearing surface or a lower cloth layer and complete the entire film-forming process at the same time during the transportation stroke, but the current prior art does not reveal such a concept, causing Increase the difficulty of wet adhesive film process, which is not conducive to the development of wet adhesive film (mask)

[0008] Second, in terms of the existing film-forming process and related manufacturing equipment, such as EU patent EP2111926A1 (international application number: PCT / JP2008 / 050822, international publication number: WO2008 / 0090892), manufacturers cannot continuously And fast production of carrier-free or carrier-based wet adhesive films

Because the film-forming process of wet adhesive film at least includes: coating operation of colloid (such as alginic acid) and its device (or workstation); coating operation of fixative (such as salt compound) and its device (or workstation); and A device (or workstation) for the colloid and fixative of the above two film-forming materials to be cross-linked to a predetermined level and / or a suspension device (or workstation) that can stop the cross-linking to solidify and form a suitable soft However, the existing manufacturing equipment lacks an efficient layout in the arrangement of the film forming process. The manufacturing equipment disclosed in EP2111926A1 is mainly to set separately an injection coating machine (impregnation coater) and a gravure printing machine (gravure coater) Two main workstations, and then use multiple idlers (rollers without power, used to support or change the direction of the conveyor belt) or the steering and / or traction of the runners to make a continuous support for the substrate Can pass through these two main working areas in sequence, for performing salt compound (i.e. the fixed solution referred to in the present invention) and alginic acid (i.e. referred to in the present invention) respectively on the surface of the continuous support substrate. Colloid) coating operation, so the lack of a coherent conveyor belt for carrying the support substrate in the whole manufacturing equipment and film-forming process, so that each film-forming material such as alginic acid (colloid) or salt compound (fixative solution) ) cannot continuously and quickly carry out and complete the film-forming process of the wet mask through the support substrate; that is, the manufacturer often has to set a plurality of separate and independent workstations (as in EP2111926A1 Figure 2-4 The injection coating machine (impregnation coater) and the gravure printing machine (gravure coater) two main working areas that are separately set as shown) and multiple additional conveying devices (such as multiple idler wheels or runner), in order to carry out and complete the film-forming process of the wet adhesive film, resulting in the overall manufacturing equipment and its manufacturing process being relatively complicated (as in EP2111926A1 Figure 2-4 As shown), it occupies a large volume, which relatively increases equipment and manufacturing costs, but cannot achieve the effect of continuously and rapidly performing and completing the film forming process

[0009] Third, the wet adhesive film mainly includes carrierless and carrierless. However, based on the existing technology, the manufacturer cannot use the basic device of the same set of manufacturing equipment, so that it can choose to manufacture the carrierless film through simple replacement or addition. And any kind of wet adhesive film (mask) with carrier, that is, if the manufacturer originally used a set of manufacturing equipment to manufacture non-carrier wet adhesive film, when the needs of consumers or customers change from non-carrier wet adhesive film When forming a wet-type adhesive film with a carrier, the manufacturer cannot use the basic device of the same set of manufacturing equipment to simply replace or add it for the production of a wet-type adhesive film with a carrier; generally speaking, the manufacturer designs another set New manufacturing equipment is used to manufacture wet adhesive films with carriers, which relatively causes waste of manufacturing equipment and increased manufacturing costs, and increases the use of space, which is not conducive to the competition of the adhesive film (mask) industry

[0010] In fact, the inventors of this case found that, in terms of a set of manufacturing equipment used to manufacture wet-type adhesive films, no matter whether they are carrier-based or carrier-free, the adhesive films used to form the main part of the wet-type adhesive film (such as alginate Film) each different basic devices (or workstations), such as each workstation (described later) such as a first fixative coating device, a colloid coating device and a second fixative coating device disclosed in this case As far as the operation functions of each workstation and the arrangement in the production process are concerned, they can generally be regarded as the same or similar, that is, the operation functions of each workstation have commonality; however, the prior art such as EP2111926A1 is often only designed It is used to manufacture a single type of wet mask, such as one with a carrier or one without a carrier. Therefore, when the manufacturer wants to manufacture two kinds of wet masks without a carrier and with a carrier, it is necessary to set up two sets of different manufacturing equipment to manufacture them separately. Therefore, the prior art does not consider the commonality of the operating functions of each workstation, and therefore does not make proper arrangements in the production process, so that the device structure and the manufacturing process of each workstation in the overall manufacturing equipment are relatively complicated (as in EP2111926A1 Figure 2-4 As shown), it occupies a large volume, and the manufacturer cannot use the same set of manufacturing equipment to make it simple replacement or addition, so that the manufacturing end can choose to manufacture two types of wet masks without a carrier and with a carrier, and the relative increase in equipment and Manufacturing costs, but still unable to achieve the effect of continuous and rapid film formation process
