Abstract

The present invention relates to a system for manufacturing an oral dissolving film (ODF) for front coating using a slot die. According to the present invention, since a single slot on the front side of a slot die extends in the width direction and, at the same time, a raw material is discharged through the single slot, a slot area is increased in comparison with a slot die width, so that a discharge amount is significantly increased in comparison with when the slot is made up of a plurality of slots, thereby maximizing production. A static electricity removal device and a separation prevention means are installed between an end part of a separation unit and a packaging unit, so that a phenomenon in which the raw material deviates from a path by static electricity, vibration, and the like or has a distorted posture can be effectively prevented when the raw material that has passed through the separation unit is transferred to a lower wrapper. A part of sliding shields is selectively lowered according to control of an operator and the number and width of the slots of the slot die are determined by the lowered sliding shields, so that ODFs of various widths and thicknesses can be manufactured without replacing parts such as dispersion diaphragms, installation costs can be reduced, and process efficiency can be maximized.

ODF manufacturing apparatus for front coating using slot die TECHNICAL FIELD

The present invention relates to an ODF manufacturing apparatus for front coating using a slot die, and in detail, by removing the process of tilting and horizontal movement of the slot die, raw material discharge is continuously performed without stopping, and at the same time, the slot is As it is configured so that the raw material is completely coated through a single slot by extending in the width direction, the production volume is maximized compared to the same process time, making it suitable for mass production, and by reducing the mass deviation of the coated raw material in the width direction through the change of the structure of the slot die, the manufacturing accuracy and It relates to an ODF manufacturing apparatus that can dramatically improve product completeness.

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.

To solve this problem, a domestic utility model No. 10-1851223 (name of the 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.

The drying unit 104 dries the liquid raw material on the coating conveyor 103 to form a gel.

The cutting unit 105 cuts the liquid raw material gelled by the drying unit 104 to a predetermined size.

The packaging unit 106 packs the liquid raw material cut to a predetermined size by the cutting unit 105.

In this prior art 100, since the liquid raw material is continuously injected into the coating conveyor 103 while the coating machine 102 is fixed, a larger amount of oral dissolving film (ODF) within the same time than the conventional manufacturing method. Can produce.

In general, the liquid raw material of ODF not only has a high surface tension due to viscosity and cohesiveness, but also has a characteristic of being supplied to the inner space of the long-width coater 102 through a single hose. Accordingly, the liquid raw material accommodated in the coating machine 102 is mainly agglomerated (aggregated) in the area adjacent to the hose due to its own viscosity, cohesive force, and surface tension, so that capacity or mass deviation occurs as it is spaced outward from the area adjacent to the hose. Has.

In order to solve this problem, a certain amount of time must elapse in the state of being accommodated, but due to the operation characteristic of continuously discharging the raw material contained inside and inflowing the raw material from the outside, the ejector is discharged in a state that is not evenly distributed, depending on the position of the width. They have different discharge pressures, and accordingly, there is a structural limitation in that the mass deviation in the width direction of the raw material coated on the base film increases.

That is, in the prior art 100, since the liquid raw material contained in the coating machine 102 is not uniformly distributed in the receiving space, that is, the mass in the width direction of the liquid raw material coated on the base film because it is discharged in an aggregated state by surface tension. It is difficult to produce a product with a uniform thickness due to the wide variation, and there is a problem that the manufacturing precision and product completion are poor.

This has a difficult drawback.

In addition, in the prior art 100, since the liquid raw material discharged by the coating machine 102 is extended in the length direction to the base film, but is coated in a row shape spaced apart from each other in the width direction, the coating machine 102 is formed as a single discharge port, Compared to the case of coating, it has a disadvantage that the production amount is inferior to the same processing time.

At this time, the sliding shields 91112 are installed to be in close contact so that the raw material does not flow into the interior, and although not shown in the drawing, the sliding shields 91112 are sealed or packed between the sliding shields 91112 to thoroughly block the inflow of raw materials into the interior. Make it possible.

These sliding shields 91112 determine the size of the slot of the second slot die 91 when descending, so that the second slot die 91 can discharge raw materials in various widths and thicknesses.

In addition, the sliding shields 91112 protrude to the same height as the thickness of the dispersion diaphragm 213 when descending.

That is, conventionally, only an oral dissolving film (ODF) having a fixed width and thickness with a slot die can be manufactured, and in order to change the width and thickness of the oral dissolving film (ODF), it is necessary to redesign the equipment suitable for the width and thickness Therefore, not only the process efficiency is lowered, but also installation and manufacturing costs increase, and there is a problem that the process time is delayed. By alternatively descending, it is possible to manufacture an oral dissolving film (ODF) of various widths and thicknesses without replacing parts such as a dispersion diaphragm.

For example, as shown in Figure 13, the second slot die 91 is a part of the sliding shield (91112) (C') is raised and lowered by the operator, some of the sliding shield (91112) (C) May be lowered, and accordingly, the second slot die 91 may form a total of 12 slots, thereby discharging the raw material in 12 rows.
