Abstract

An extruder for manufacturing a vinyl bag is provided to supply a vinyl bag having at least two colors at a low cost without performing additional printing work relative to the vinyl bag. An extruder for manufacturing a vinyl bag comprises a nozzle(1) and a first heater(2) installed on the outside of the nozzle. The heater allows vinyl solution to maintain a molten state. An air ring is disposed on the heater to cool a vinyl bag film. A second heater melts vinyl bag film material. A transfer pipe(7) having a transfer screw transfers the molten vinyl bag film material. Vinyl solution supply paths(4) are formed at the inner lower side of the nozzle so that vinyl solution having at least two colors is supplied. A circular extrusion hole(5) is formed in the upper portion of the nozzle so that one cylindrical vinyl bag film is extruded.

The present invention relates to an extruder for producing a plastic bag, and more particularly, a vinyl bag configured to manufacture a plastic bag having two or more colors in order to be able to provide a plastic bag for use in various purposes in a more diverse design. It relates to an extruder for bag production.

As is well known, plastic bags are mainly used in the distribution process because they can be mass-produced at low cost and have convenient advantages when transporting or storing various items.

In addition, even when local governments collect and dispose of garbage, local governments produce plastic bags printed with designs and phrases that have separate characteristics and sell them to residents.

Conventionally, plastic bags for product packaging or garbage collection as described above have a whole gray plastic bag in order to make the contents invisible, and as described above, they are characterized by local governments in order to recognize the source of local governments. The phrase and logo are printed and the size is divided into large, medium and small.

Users can have a disgust when they print only the phrases and logos with distinctive characteristics that can be distinguished by local governments by using plastic bags manufactured in monochrome such as gray.

And, even in the case of a plastic bag for packaging products used in marts because it is formed in a single color there was a disadvantage that can not provide a plastic bag for packaging products having a variety of designs.

In order to solve the shortcomings of these plastic bags and to provide plastic bags with various designs, the design was produced by printing on the outer surface of the plastic bags.

When the design is produced by printing on the outer surface of the plastic bag as described above, it is possible to provide a plastic bag having a variety of designs, but there were problems such as environmental pollution and cost increase by using dyes through printing.

An object of the present invention for solving the above problems is to produce a variety of designs of plastic bags for packing various kinds of plastic bags or garbage, as well as a variety of designs when extruding plastic bag film It is intended to provide an extruder for producing a plastic bag that can produce a plastic bag of various designs without a separate printing process after manufacturing the plastic bag to have a desired purpose.

Extruder for producing a plastic bag of the present invention for achieving the above object is provided with a nozzle consisting of separate vinyl solution supply paths and circular extrusion holes connected to the vinyl solution supply path to form two or more color lines, The nozzle is connected to a conveying screw and a conveying tube equipped with a heater and a hopper for inputting a material, and the materials having different colors are melted and conveyed through different paths (conveying screw and conveying tube), and then interconnected by the nozzle. It is characterized in that it is extruded into a plastic bag film, described in detail with reference to the accompanying drawings as follows.

1 is a perspective view showing a preferred embodiment of the present invention, Figure 2 is an exploded perspective view of the main structure according to the present invention, Figure 3 is an enlarged cross-sectional view taken along line AA 'of Figure 2 according to the present invention, Figure 4 is the present invention 2 is an enlarged cross-sectional view of the line B-B ', Figure 5 is a cross-sectional view showing a portion of the transfer screw according to the present invention.

As shown in the figure, the extruder for producing a plastic bag of the present invention is installed on the outside of the nozzle (1) constituting the extruder to install a heater (2) to maintain the molten state of the vinyl solution, and to cool the plastic bag film thereon Air ring (3) is configured to allow

In the lower side of the nozzle (1) to form a separate vinyl solution supply path (4) to form two or more color lines,

A circular extrusion hole 5 is formed so that the upper ends of the vinyl solution supply passages 4 constituting the nozzle 1 are interconnected, and the vinyl solution supply passages 4 are transported so that the vinyl solution can be supplied. To connect the transfer pipe (7) with a screw (6),

The heater 8 is installed outside the transfer pipe 7 so as to melt the material, and one side of the transfer pipe 7 is provided with a hopper 9 so that different materials may be supplied.

In the drawings, reference numeral 50 denotes a gearbox, 51 a cover, 53 an air hose, 54 a plastic bag film, and 55 a plastic bag film winding roll.

 Referring to the action related to the extruder for producing a plastic bag according to the present invention will be described in detail.

First, by supplying energy to the plastic bag production extruder according to the present invention to operate, air is injected into the air ring 3 to cool the plastic bag film, the heater is heated, and the transfer screw is rotated.

In this state, the plastic bag film material is introduced through the hopper 1 constituting the plastic bag manufacturing extruder, and materials of different colors are added.

Then, the material is conveyed to the nozzle 1 by the conveying tube 7 and the conveying screw 6, and the conveying tube 7 is heated by a heater 8 provided outside the conveying tube 7. Therefore, the material is supplied to the nozzle 1 in a state where the material is melted and becomes a vinyl solution. Since the materials having different colors are supplied to the hopper 9, vinyl solutions of different colors are supplied to the nozzle 1.

More specifically, the vinyl solution having a different color is introduced through the vinyl solution supply passages 4 constituting the nozzle 1 by the above-described process, and the color is passed through the circular extruded holes 5 interconnected to each other. The other vinyl solution is interconnected and extruded into the plastic encapsulation film 54, and is also cooled by the air ring 3 to complete the plastic encapsulation film 54 and is wound on the plastic encapsulation film winding roll 55.

In the process of manufacturing the plastic bag film as described above, if the plastic bag film material and the luminous particles are put together in the hopper can produce a plastic bag that is luminous.

According to the extruder for producing a plastic bag of the present invention as described above, a material with different colors can be made into a vinyl solution through different paths, and at the end can be interconnected to produce a plastic bag film of different color lines. There is an effect that can easily provide a plastic bag having a, so that there is no effect to supply a plastic bag having a variety of designs at a low cost without a separate printing on the plastic bag, and thus produced plastic bag film for waste collection When used as a plastic bag, there is an effect of reducing the aversion to the garbage bag.

Claims (1)

The outside of the nozzle 1 is provided with a heater 2 to maintain the molten state of the vinyl solution, and an air ring 3 for cooling the plastic encapsulation film thereon, and the plastic encapsulation film material is formed. In the plastic bag manufacturing extruder consisting of a transfer pipe (7) having a heater (8) and a transfer screw to melt and transfer, A circular extrusion hole is formed in the lower part of the nozzle 1 so as to form separate vinyl solution supply paths 4 so that a vinyl solution having two or more colors can be supplied, and one cylindrical vinyl encapsulation film is extruded thereon. 5) to be connected, In the lower part of the vinyl solution supply paths (4) provided with a transfer pipe (7) provided with a transfer screw (6) so that the vinyl solution can be supplied to each of the hopper (9) so that different materials can be supplied Extruder for producing plastic bags, characterized in that.
