It relates to an ODF manufacturing apparatus that can be made.

Oral dissolving film (ODF) is a film that is pasted and dissolved in the oral cavity such as the tongue, oral mucosa, and sublingual, and is a film that is harmless to the human body such as starch, and a material that is beneficial to the human body is mixed inside the material that is soluble in water. Is formed by

Such an oral dissolving film is manufactured by a method in which the coating solution is sprayed at regular intervals on a silver base film paper, and individually wrapped by a wrapping paper in a state where the coating solution is dried through a dryer.

However, in such a manufacturing process, the coating liquid spraying nozzle for spraying the coating liquid is subjected to tilting, reversing, and forward operation after spraying the coating liquid once, thereby causing a problem that the manufacturing time of the oral dissolving film as a whole increases.

In order to solve this problem, domestic utility model No. 10-1851223 (name of invention: plate-shaped ODF manufacturing facility and its manufacturing method) (hereinafter referred to as'conventional technology') was developed.

1 is a perspective view of the prior art.

As shown in Figure 1, the prior art 100 is a raw material supply container 101, a coating machine 102, a coating conveyor 103, a drying unit 104, a cutting unit 105, a packaging unit 106 Consists of

The raw material supply tank 101 contains a liquid raw material therein, and is connected to the coating machine 102 by a hose equipped with a valve.

The coating machine 102 receives the liquid raw material from the raw material supply container 101 and discharges the liquid raw material to the coating conveyor 103.

At this time, the coating machine 102 is configured such that the discharge ports (not shown) are formed to be spaced apart at predetermined intervals in the width direction, so that when the liquid raw material is discharged to the coating conveyor 103, it is discharged to the coating conveyor 103 in a plurality of rows.

In these raw material pipes 9121, the raw material (B) introduced into the upper space (S1) is transferred at a constant hydraulic pressure by the hydraulic control valve (91211), and since they are installed at regular intervals, the raw material (B) is stored in the lower space (S2). It is conveyed evenly.

The discharge port 911 is formed at the lower front side of the discharge machine 91, and is connected to the lower space S2 so that the raw material B transferred to the lower space S2 is discharged to the outside.

In the discharger 91 configured as described above, the raw material B introduced into the upper space S1 through the supply hose 23 is evenly distributed to the raw material pipes 9121 by the shape of the upper surface of the hydraulic control unit 912. Flow in.

In addition, the raw material (B) flowing into the raw material pipes 9121 is uniformly transferred to the lower space (S2) by the hydraulic control valve (91211), and in the width direction on the base film (A) by the discharge port (911). It is evenly discharged.

As described above, the ODF manufacturing apparatus 1 according to an embodiment of the present invention has a single discharge port in the front of the dispenser extending in the width direction and is configured to discharge raw materials through a single discharge port, thereby increasing the discharge port area compared to the width of the discharge machine. Compared to the case where a plurality of slots are formed, the amount of discharge can be significantly increased to maximize the amount of production.

In addition, the ODF manufacturing apparatus 1 of the present invention is configured to discharge raw materials using a simple and inexpensive ejector instead of a slot die having a complex structure and an expensive structure, so that manufacturing cost can be significantly reduced and the structure is simple. Time and cost consumption due to equipment failure and inspection can be effectively improved.

In addition, the ODF manufacturing apparatus 1 of the present invention has a complex structure as the comma coater is installed to be spaced apart from the base film in a position adjacent to the discharge port of the dispenser, and at the same time, the separation distance from the base film can be adjusted according to the control of the controller. It is possible to precisely control (control) the thickness of the raw material through a simple operation without using a separate thickness control means or an expensive thickness measurement means, thereby increasing process efficiency and further reducing manufacturing costs.

In addition, in the ODF manufacturing apparatus 1 of the present invention, the internal space of the ejector is separated into an upper space (S1) and a lower space (S2) by a hydraulic control unit, and the raw material accommodated in the upper space (S1) inside the hydraulic control unit A plurality of raw material pipes that transfer the material to the lower space (S2) are installed in the width direction, and the upper surface of the hydraulic control unit exposed to the upper space (S1) is formed in a curved surface downward from the middle point in the width direction toward the outside. By moving the raw material contained in the space (S1) to the outside, the variation in the capacity of the raw material due to its own viscosity, cohesive force and surface tension is improved so that a sufficient amount of raw material is introduced into the raw material pipes arranged outside, and the discharged raw material accordingly By effectively reducing the mass deviation in the width direction of the product, it is possible to further increase product completion and manufacturing precision.

In addition, in the ODF manufacturing apparatus 1 of the present invention, the hydraulic control valves are installed in each of the raw material pipes of the hydraulic control unit, so that the raw material can be moved from the upper space to the lower space with a uniform hydraulic pressure according to the control of the hydraulic control valve. And variations in the discharge mass can be further improved.

In addition, in the ODF manufacturing apparatus 1 of the present invention, the static electricity removal device and the separation prevention means are installed between the end of the separation unit and the packaging unit, so that the path is deviated by static electricity or vibration in the process of being transferred to the lower packaging paper of the raw materials passing through the separation unit. It is possible to effectively prevent the phenomenon of being distorted or distorted posture.
