Description

{WOUND FILM CUTTING DEVICE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a winding film cutting apparatus, and more particularly, to a winding film cutting apparatus that can cut both sides of a film wound in a roll shape according to a standard.

In the field of packaging, packaging materials in the form of roll films have been developed and used for various purposes such as preservation of foods and storage of garbage. In recent years, an envelope-shaped packaging material has been used for storage of food and the like, and a vacuum packaging material has also been used.

Such a packaging material is manufactured in the form of a film and is supplied in the form of a roll wound around a branch pipe for convenience of storage and use of the packaging material.

Since the packaging material must be cut and used as much as the user needs, a cutting area is formed at a predetermined length. Since the cutting area is formed at an arbitrary size at the time of manufacture, Must be selected and used. Therefore, there is an inconvenience that packaging materials of various sizes must be provided.

On the other hand, in order to form a perforated line at a predetermined length in the manufacturing process of the packaging material in the form of a roll film according to each standard, an apparatus for forming a perforated line must be provided. In order to form such a perforated line, It requires know-how and expertise in manufacturing. In addition, since it is necessary to produce roll films of various sizes, the apparatus and the process according to the respective standards must be provided, respectively, and therefore, sufficient space must be provided due to the excessive process equipment.

Therefore, the roll film is supplied with the most widely used width, and the size of the roll film provided by allowing the user to cut the roll film to be used in an arbitrary length can be reduced to a range of the universal standard It is necessary to make efforts to

On the other hand, in the case of a wrapping material provided in the form of a roll film, a structure in which a sawing-type cutting device is attached to a packaging container is used, but the cutting device in the form of a sawtooth attached to the packaging container is not easily cut , The packaging material tends to be torn in a region other than the cutting region, which is rather inconvenient to use. These problems have caused the users to cut the packaging material using knives or scissors rather than using the cutting device attached to the packaging material.

Furthermore, since the saw-toothed cutting device attached to the packaging container of the wrapping package is constituted in such a state that the cutting region (sawtooth region) is exposed to the outside, a safety accident occurs such as a user being injured at the time of use. In order to prevent such a safety accident, the cutting area of the cutting apparatus has been recently provided with a blunt state, and thus the cutting efficiency is lowered.

On the other hand, the background art described above is technical information acquired by the inventor for the derivation of the present invention or obtained in the derivation process of the present invention, and can not necessarily be a known technology disclosed to the general public before the application of the present invention .

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

1 is a view showing a schematic configuration of a winding film cutting apparatus according to an embodiment of the present invention.

Referring to FIG. 1, a winding film cutting apparatus 10 according to an embodiment of the present invention includes a film loading unit 100 and two cutouts 200-1 and 200-2.

The film loading unit 100 rotates the film roll 110 in a clockwise or counterclockwise direction after the film roll 110 wound thereon is wound and the two cutouts 200-1 and 200-2 are arranged on the upper side, (Not shown).

At this time, the film roll 110 can be transferred from the outside to the film loading unit 100 by the separately installed hoist 300.

The cutting unit 200 cuts the film roll 110 using a rotary blade so as to cut the film roll 110 at a predetermined width (that is, a length corresponding to the width of the film required to be cut) And is spaced apart from the upper side of the film loading section 100.

The winding film cutting apparatus 10 having the above-described configuration may further include a remote controller (not shown in the figure for convenience of explanation) for controlling the driving of the film loading unit 100 or the cutter 200.

The remote controller controls the rotational direction or rotational speed of the film roll 110 in the mounting portion 100 or the driving of the rotary knife in the cut portion 200 using a wired or wireless network.

In one embodiment, the outer shape of the remote controller can be made of a plastic sheet having superior moldability and durability than a plastic sheet produced by using PET resin alone.

The plastic sheet according to the present invention is produced by the following method for producing a plastic sheet.

2, a method of producing a plastic sheet for producing a plastic sheet according to the present invention comprises: 100 parts by weight of a polyethylene terephthalate (PET) resin, 2 to 4 parts by weight of a polyurethane dispersant, 0.1 to 0.2 part by weight of polyethylene dioxythiophene polystyrene sulfonate, 3 to 5 parts by weight of polystyrolsulfonic acid, N-methyl-2-pyrrolidone, 0.1 to 0.3 parts by weight of triethylamine, 42 to 45 parts by weight of isopropyl alcohol and 50 to 52 parts by weight of water to prepare a mixed composition (S110); A second step (S120) of preheating the mixed composition; A third step (S130) of removing moisture from the preheated mixed composition; A fourth step (S140) of heating the moisture-removed mixed composition; A fifth step (S150) of removing foreign substances from the heated mixed composition; A sixth step (S160) of stretching the mixed composition from which the foreign substances have been removed while cooling it to produce a plastic sheet; And a seventh step (S170) of applying silicone to the plastic sheet and drying the plastic sheet.

The present invention can produce a plastic sheet having excellent moldability and durability by preheating, dehumidifying, heating and cooling by mixing various additives with conventional PET resin.

In the first step S110, as a mixing step of the raw materials, polyethylene terephthalate (PET) resin is used as a base resin, and a polyurethane dispersant, polyethylene dioxythiophene polystyrene sulfonate ), Polystyrolsulfonic acid, N-methyl-2-pyrrolidone, triethyl amine, isopropyl alcohol and water. .

The PET resin is a base resin, which has excellent thermal stability and high crystallinity, can be recycled, and is manufactured in a master batch form. The polyurethane dispersant functions to improve the compatibility with other components. Polyethylene dioxythiophene polystyrene sulfonate, polystyrolsulfonic acid, N-methyl-2-pyrrolidone, and triethyl amine. Function as an antistatic agent. Since the plastic sheet for producing the plastic container is generally an electrical insulator, static electricity is generated by friction charging, and if it is seriously damaged by discharge or electric conduction, it may lead to an accident such as explosion or fire, so it is preferable to add a charging agent . Isopropyl alcohol functions as an antifogging agent. The anti-fogging agent can inhibit the formation of water droplets due to the water vapor which may be generated when a plastic container is used to store a fruit or the like by using a plastic sheet.

In one embodiment, the above ingredients are mixed with 100 parts by weight of a polyethylene telephthalate (PET) resin, 2 to 4 parts by weight of a polyurethane dispersant, polyethylene dioxythiophene polystyrene sulfonate ), 0.4 to 0.6 parts by weight of polystyrolsulfonic acid, 3 to 5 parts by weight of N-methyl-2-pyrrolidone, 0.1 to 5 parts by weight of triethylamine amine in an amount of 0.1 to 0.3 part by weight, 42 to 45 parts by weight of isopropyl alcohol and 50 to 52 parts by weight of water. When added beyond the above-mentioned range, various problems may occur. Particularly, in the case of an antistatic agent, when mixed over the respective ranges, the plastic surface to be produced may be sticky, the sealing property and printability may be deteriorated, and in the case of white plastic, yellowing may occur.

In addition, the first step (S110) can further mix various additional components in the raw materials to enhance the functionality of the plastic sheet.

In one embodiment, the boron-based binder may be further mixed. The boron (B) type binder is used for bonding the respective components, and the boron type binder is preferably mixed in 2 to 10 parts by weight with respect to 100 parts by weight of the PET resin. When the content of the boron-based binder is less than 2 parts by weight, the raw material or the like can not be effectively bonded, and when the content of the boron-based binder exceeds 70 parts by weight, it is uneconomical.

In one embodiment, the garlic extract may be further mixed. The garlic extract is a natural adhesive component, which together with the boron-based binder functions as a binder which improves the compatibility with other constituents. The garlic extract is peeled and crushed, and 2 to 3 parts by weight of water is added per 1 part by weight of garlic. After heating at 80 to 100 캜 for 5 hours or more, the liquid component is extracted and filtered, The liquid component can be prepared by concentrating at 55 to 60 占 폚. The garlic extract is preferably mixed in 5 to 10 parts by weight with respect to 100 parts by weight of the PET resin. When the content of the garlic extract is less than 5 parts by weight, the raw material components may not be properly entangled so that the surface of the plastic sheet may not be uniformly formed. When the amount of the garlic extract is more than 10 parts by weight, There is a risk of degradation.

In one embodiment, the apatite powder may be further mixed. The apatite powder functions as a filler and can maintain the shape of the plastic sheet, thereby improving workability and improving strength and corrosion resistance. Apatite is an inorganic substance present in bone. It is important to use a small amount of particles, a high residual amount of carbonate, and low crystallinity for use as a filler. Preferably, the size of the apatite granules is 200 to 400 탆. For this purpose, it is important to carry out the sintering process at 500 to 700 ° C. When sintering at less than 500 ° C, there is a disadvantage in that the desired granule size and crystallinity can not be obtained. When sintering exceeds 700 ° C, there is a disadvantage in that the remaining amount of carbonate is low and the crystallinity becomes too high. The apatite powder is preferably mixed in 20 to 30 parts by weight with respect to 100 parts by weight of the PET resin. When the content of the apatite powder is less than 20 parts by weight, there is a disadvantage in that the adhesive strength is lowered, and when it exceeds 30 parts by weight, the impact resistance is weakened.

In one embodiment, the cork powder may be further mixed. Cork powder can improve the durability of the plastic sheet with apatite powder. The cork powder can be prepared by removing the shell of oak oak and then crushing it. For the cork powder to be mixed with the PET resin and the like, it is preferable to use fine pulverized particles which have been passed through a mesh of 400 mesh or more. The cork powder is preferably mixed in 15 to 25 parts by weight with respect to 100 parts by weight of the PET resin. When the cork powder is less than 15 parts by weight, improvement in durability is insignificant. When the cork powder is more than 25 parts by weight, porosity may be formed in the production of plastics, and durability may be lowered.

In one embodiment, the Sorghum extract can be further mixed. Sorghum extract not only acts as an antimicrobial agent but also inhibits the yellowing of white plastic sheets. Rumex crispus is a genus of Rumex spp. It is a perennial herb that grows well in moist places of various places. It uses the lysoon as a food in the private sector. In the oriental medicine, it is called a yosei, and it is categorized into various diseases including cystitis, gallbladder disease, bile secretion disorder, spleen disease, It is used as an adjuvant treatment for tumors and cancer. Sorghum extract extracted from Sora japonica has antimicrobial and antioxidant effects against various microorganisms. When mixed with a small amount of sulfur, it has an excellent effect on skin itching. It has been reported that saponins, tannins, flavonoids, essential oils and chrysophanol, and anthraquinone derivatives such as emodin, are known to be useful components of the present invention. The extracts of Sorae Seedlings were washed in 80% (v / v) methanol for 3 days as an extraction solvent by washing the collected Sorghum wells and then drying them in the shade and dividing them into the ground part (except the root) and the root part (root part) After soaking, the extract is filtered with a membrane filter (pore size 0.5 mu m) to separate the solid, and the methanol extract can be prepared by concentrating the extract at 50 DEG C using a rotary evaporator. It is preferable that the Sorghum extract is mixed in 3 to 8 parts by weight with respect to 100 parts by weight of the PET resin. When the content of the extract is less than 3 parts by weight, the antimicrobial activity is insufficient in preventing yellowing, and when it is more than 8 parts by weight, it is uneconomical.

The second step (S120) is a step of preheating the mixed composition, and heat is applied to the mixed material so that the materials are stably mixed.

The third step (S130) is a dehumidifying step for removing moisture present in the preheated mixed composition, and the desiccation is preferably performed in a temperature range of 150 to 180 ° C. If the amount is less than or more than the above range, the dehumidification may not be sufficiently performed, or the durability of the plastic may be adversely affected.

The fourth step (S140) is a step of heating the mixed composition from which moisture has been removed, and the heating temperature is preferably controlled to 260 to 270 ° C in order to melt and maintain the mixed composition.

The fifth step S150 is a step of removing foreign matter from the heated mixed composition. The foreign matter may be removed from the inside of the mixed composition by passing through a screen in the form of a mesh.

The sixth step (S160) is a step of cooling the mixed composition from which foreign matters have been removed to prepare a plastic sheet, which is then stretched in two stages using a cooling roll. The primary stretching takes place in the longitudinal direction through a chill roll maintained at 16-17 캜 and the secondary stretching takes place in the width direction (vertical direction in the longitudinal direction) through a cooling roll maintained at 20-23 캜. The reason for raising the temperature of the secondary elongation to be higher than the primary elongation temperature is to prevent the plasticizability of the solidified plastic sheet from being dried and to improve the durability and moldability of the plastic sheet by alternately stretching the longitudinal direction and the width direction .

The seventh step (S170) is a step of applying silicone to the plastic sheet and then drying it, so that the antistatic effect can be obtained while the silicone is applied and finished. It is preferable that silicone is applied using a diluted coating liquid in a concentration range of 5 to 25%, coated with silicone, and then dried at 160 to 215 캜. Further, it is preferable that the anti-fogging agent component is mixed with the silicone-containing coating liquid in order to suppress the water phenomenon formed in the produced plastic container.

Hereinafter, the structure and effects of the present invention will be described in more detail with reference to specific examples and comparative examples. However, this embodiment is intended to explain the present invention more specifically, and the scope of the present invention is not limited to these embodiments.
