The present invention relates to an apparatus for forming an environment-friendly biodegradable starch container, and more particularly, to manufacture a biodegradable disposable container using starch, etc. as a main material, but to mold a kneaded raw material in a predetermined form. The opening and closing operation of the mold frame is made by the mechanical mechanism between the guide rail and the opening / closing conductor without using a separate power device in opening and closing, so that an efficient container can be manufactured with a simple configuration. The present invention relates to an apparatus for forming an improved biodegradable starch container having a structure in which a plurality of molds are arranged in the mold, which enables continuous automatic production and does not take up much space for installation.

As is well known, disposable products such as, for example, outdoor lunch boxes, packaging dishes such as meat / fruits, and instant ramen containers are molded from plastics such as polystyrene as the main material, which is very light and priced. In addition, the use is increasing rapidly in the field of disposable tableware, food packaging, etc. in recent years.

Such disposable products are generally discarded after being used once. Disposable products made of plastics as described above have a very bad effect on the environment because they are not decomposed for a long time even if they are embedded in soil. .

In order to improve the problems of the conventional plastic containers, recently, biodegradable disposable containers using grain starch such as corn, sweet potato, potato, or the like as grains, fish meal, meat flour, etc. are known and used. That is, in the case of the biodegradable containers as described above, unlike containers using plastics, even if the used product is discarded, there is a property to prevent environmental pollution such as soil pollution by natural decomposition after a certain time in a natural state. It is receiving great attention as a means to replace existing plastic products. In particular, the annual demand for plastics around the world is about 100 million tons, and the market for disposable plastic containers is only 100 trillion won. Is expected to achieve explosive growth in the future.

However, despite these advantages, in the case of biodegradable disposable containers using starch or the like, there was a problem in mass production due to insufficient development of a device that can efficiently produce the product, and accordingly, the manufacturing cost is increased considerably. So far, it has not been widely used in the field compared to conventional plastic containers.

On the other hand, in view of the problem of mass production, a starch container manufacturing apparatus has been developed that enables the continuous production of starch containers in the past, as an example there may be Republic of Korea Patent No. 0538121. However, the prior patent has the advantage that the continuous production is possible by manufacturing the starch container circulating through the conveyor belt, while the installation due to the conveyor belt forming a rectangular track path as shown in FIG. There was a drawback in that it requires quite a lot of space, and there is also a problem that the manufacturing cost for the device is high due to the separate installation of a drying furnace for the installation and heating molding of the conveyor belt.

Therefore, the present invention was devised in view of the problems with the conventional apparatus for manufacturing a biodegradable disposable container as described above, specifically, the present invention is a biodegradable disposable container using a material such as starch as the main material In the opening and closing of the mold mold to pressurize and mold the kneaded raw material into a certain form, the opening and closing operation of the mold mold is made by a mechanical mechanism between the guide rail and the opening and closing conductor without using a separate power device. It is possible to manufacture an efficient container, and has a configuration in which a plurality of mold frames are arranged on a circular rotating base, which enables continuous automatic production and improved eco-friendly biodegradable starch container that does not take much space for installation. The technical problem to be solved is to provide a molding apparatus.

In order to achieve the above technical problem, the molding apparatus of the eco-friendly biodegradable starch container provided by the present invention includes: (a) a rotation base configured to axially rotate in a horizontal direction with respect to the ground; (b) a guide rail which is disposed on an upper side of the rotating base and is an arc-shaped rail member having a change in height; And (c) a lower mold frame fixed to an upper surface of the rotating base and configured to mount a lower mold therein; An upper mold frame rotatably connected to an upper side of the lower mold frame and configured to fire the upper mold therein; It is provided on one side of the upper mold frame and the lower portion of the mold assembly including; opening and closing inductor installed in a state supported on the guide rail; comprising a basic feature.

In addition, as a more preferable configuration for the present invention as described above, in the present invention, a clamping pin is provided on one side of the lower mold frame, and the upper mold is provided with a hook having a shape of engaging with the locking pin. Further mounted in a rotatable state, the opening and closing conductor may be configured to be connected to one side of the clamp.

The guide rail may further include a rising part forming a rising path along a length direction thereof; A horizontal portion extending in the horizontal direction from the rising portion; It may be to include; a falling portion connected to the horizontal portion to form a falling path, which is also one of the features of the present invention as a preferred configuration.

Also preferably, the lower side of the guide rail in the present invention may be configured to be provided with a push wheel formed to press the upper surface of the upper pressing plate when the mold frame assembly passes. In addition, in the present invention, at least one of the upper mold and the lower mold is preferably configured to be further equipped with a heating module, and also, the pressing surface of the upper, lower mold mounted on the upper mold and the lower mold It is preferable to configure so that a plurality of slits dug to a predetermined depth are formed.

Hereinafter, with reference to the accompanying drawings, the configuration and operation of the subject innovation as described in more detail with a preferred embodiment for the subject innovation.

Figure 2 is a plan view and a side view from the top of the molding apparatus of the eco-friendly biodegradable starch container provided by the present invention, as shown in Figure 2 the present invention is made of a disc on the upper side of the housing 100 With a rotating base 10, a plurality of mold mold assembly 20 is disposed radially on the upper surface of the rotating base 10, the upper side of the rotating base 10 at an interval at a circular arc (圓) (Iii) A guide rail 30 having a shape is formed long along the outer direction of the rotation base 10. In addition, the rotation base 10 is connected to a power rotating means such as a motor (not shown) in the lower portion so as to rotate horizontally with respect to the ground.

In addition, the mold mold assembly 20 is largely divided into a lower mold 21 and an upper mold frame 22 as shown, the lower mold frame 21 and the upper mold frame 22 by a hinge By being coupled so as to be able to rotate, the product is closed at the time of compression molding of the product, and is configured to be opened at the time of taking out the molded product and input of raw materials.

In addition, according to the illustrated embodiment, the clamp 40 is rotatably mounted at one side of the upper mold frame 22, more precisely at a predetermined position opposite to the lower mold frame 21 hinged. The opening and closing conductor 50 is connected to the side of the clamp 40 so as to protrude outward. In the present invention, the clamp 40 is closed due to the internal pressure such as steam pressure contained in the raw material while the upper mold 22 and the lower mold 21 are closed to press the raw material introduced therein to form a product. Corresponds to the opening and closing control means for preventing the upper mold frame 22 from opening. The clamp 40 has a hook 45 is formed on the lower side as shown, the hook 45 is caught by a locking pin 25 protruding from the lower mold 21, the upper mold frame 22 It is designed to prevent it from being lifted up above it.

In addition, while the clamp 40 is lifted up so that the hook 41 is released from the locking pin 25 to release the locking of the mold frame, it is possible to limit further rotation when lifted up above a predetermined angle. It is. Accordingly, when a force is applied in a direction in which the opening and closing conductor 50 installed on the side of the clamp 40 is lifted up, the clamp 40 connected thereto is first detached from the locking pin 25 to close the mold frame. As the clamp 40 is no longer rotated when the opening and closing conductor 50 is lifted, the upward force is transmitted to the upper mold 22 through the clamp 40, and as a result, The upper mold frame 22 is lifted up and opened (as will be easily understood with reference to the continuous process shown in FIG. 4).

On the other hand, according to the main feature of the present invention, the guide rail 30 is disposed on the upper side of the rotating base 10. The guide rail 30 is a relatively thin and long rail-shaped member, the shape of which is to go along the outer curve of the rotating base 10 while forming an arc shape when viewed from the top, and viewed from the side up and down It is supposed to have a change. Specifically, as shown in FIG. 3, the guide rail 30 is formed to have a rising portion 30a that forms an ascending path by gradually rising and inclining along its longitudinal direction, and extends in the horizontal direction from the rising portion 30a. The horizontal portion 30b is connected to the horizontal portion 30b, and the lower portion 30c gradually slopes downward to form a descending path.

On the other hand, when seeing the coupling relationship between the guide rail 30 installed as described above and the mold frame assembly 20 described above, as shown in Figure 3, the mold frame assembly 20 described above on the upper surface of the guide rail 30 It can be seen that the opening and closing conductor 50 of the) is configured to achieve a mounted state. Therefore, when the rotating base 10 is rotated, as the mold assembly 20 fixedly mounted thereon moves horizontally with the rotation of the rotating base 10, the mold assembly 20 is connected to the mold assembly 20. The opening and closing conductor 50 is guided to be lifted up or down by the path shape of the guide rail 30 so that the opening and closing operation of the clamp 45 and the upper mold 22 is made correspondingly. It is.

In addition, according to the illustrated embodiment, the pressing wheel 60 is installed at a predetermined height at the end portion of the guide rail 30, that is, the lower portion 30c, the mold frame assembly ( 20 is passed so that the upper surface of the upper mold frame 22 of the mold assembly 20 can be pressed by the push wheel (60). It is installed to prevent the upper mold frame 22 from being lifted up by the internal pressure due to steam or the like during the press molding of the input raw material. Of course, the above-described action may be expected by the clamp 45 described above. It is to be adopted as the preferred configuration for the present invention in order to ensure a certain pressurization.

On the other hand, in the drawings showing the present embodiment, reference numeral 70 denotes a heating module mounted on the upper mold 22 and the lower mold 21. The heating module generally corresponds to a heating means capable of heating and heating by electric power. In the present invention, the heating module may be molded in its own elevated temperature by embedding the heating module inside the mold for molding. There is no need to provide a heating / drying device, which has the advantage of saving the overall installation space. In the case of the heating module is not particularly limited in its form or method, it is preferable to use a cartridge type heat transfer heating module.

5 is a view showing a cross-sectional configuration of a mold used for mounting the upper mold 22 and the lower mold 21 in the molding apparatus of the eco-friendly biodegradable starch container of the present invention, as shown in the figure The pressing surface of the mold 20a and the lower mold 20b may be configured such that a plurality of slits 20s are formed at a predetermined depth. The spacing of the slits is about 10mm ~ 15mm is good, the depth is about 10mm is appropriate. When the slits are formed in the upper / lower molds 22a and 21b as described above, the slits may be formed due to evaporation of moisture contained in the raw materials during the compression molding of the raw materials in the elevated temperature by the heating module 70. Entering inside, it can be expected to have an advantageous effect that can prevent excessive internal pressure rise during molding / drying.

Hereinafter, an operation process of the apparatus for forming an eco-friendly biodegradable starch container of the present invention having the configuration as described above will be described with reference to FIGS. 3 and 4.

Figure 3 is a view showing the development of the mold opening and closing process according to the progress direction of the molding apparatus of the present invention, Figure 4 is a diagram showing the opening and closing process of the mold in each individual step.

First, the molding apparatus of the eco-friendly biodegradable starch container of the present invention arranges a plurality of mold frame assemblies 20 on a rotating base 10, and an arc-shaped guide rail around the rotating base 10. 30), and in the overall operation, when the rotating base 10 is rotated, the mold assembly 20 fixed thereon moves along the direction of rotation while the opening and closing conductor 50 installed thereon. Is moved in contact with the upper surface of the guide rail 30, at this time, the upper and lower height change of the guide rail 30 is reflected in the opening and closing conductor 50, the upper mold frame 22 directly or indirectly connected thereto The opening and closing of can be done automatically. That is, one of the most important features in the operation of the present invention, in the opening and closing operation between the upper mold 22 and the lower mold 21, the guide rail 30 is not provided with a separate mechanical element such as a cylinder The mechanical mechanism between the opening and closing conductor is to make the opening and closing operation of the mold.

Referring to the characteristic operation process of the present invention as described above in more detail in each step as follows.

(Iii) preparation

Before the mold assembly 20 enters the section of the guide rail 30, in this state, as shown in Figs. 3 (a) and 4 (a), the upper mold frame 22 is a lower mold The mold 21 is lowered due to the upper part of the mold 21, and the clamp 40 is also lowered by its own weight to be caught by the locking pin 25. At this time, a raw material such as starch is introduced into the mold assembly 20, and compression molding is performed by the mold.

(Ii) clamp opening step

Once the mold assembly 20 enters the beginning of the guide rail 30, the guide rail 50 moves as the guide rail 30 moves upwardly inclined upward portions 30a of the guide rail 30. Due to the shape of the 30, the opening and closing conductor 50 is gradually lifted in the upward direction. Accordingly, the clamp 40 directly connected to the opening and closing conductor 50 is lifted together so that the hook 45 of the clamp 40 is separated from the locking pin 25 to release the locking state of the mold. (See Figures 3 (b) and 4 (b).)

(Iii) mold opening step

As the mold frame assembly 20 proceeds further, the degree of lifting of the opening and closing conductor 50 also increases, and accordingly, the upper mold frame 22 is lifted beyond the opening limit of the clamp 40. As a result, the mold die is opened. (See Figs. 3 (c) and 4 (c).)

(Iii) product extraction stage

As shown in FIGS. 3 (d) and 4 (d), when the mold assembly 20 enters the horizontal portion 30b through the raised portion 30a of the guide rail 30, the opening and closing conductor ( 50) and the lifting degree of the upper mold frame 22 is at a maximum, and thus maintains the mold mold in a fully opened state for the time being. When the mold mold is completely opened as described above, the finished product of the injection molded container is taken out of the mold mold and moved by using a takeout device (not shown) installed outside the molding apparatus.

(Iii) raw material supply stage

After the finished product is taken out in the product dispensing step (iii), the raw material is introduced into the empty mold to start the next manufacturing cycle. At this time, as shown in FIGS. 3E and 4E, the mold assembly 20 continues the rising portion 30a of the guide rail 30 to almost the end of the horizontal portion 30b. The section has been reached.

(Ⅵ) mold mold closing step

3 (f) and 4 (f), when the mold assembly 20 enters the lower portion 30c through the horizontal portion 30b of the guide rail 30, the opening and closing conductor is 50 slides the upper portion of the guide rail 30, and thus the upper mold 22 gradually descends and reaches the second half of the lower portion 30c, so that the upper mold 22 is completely closed and the raw material introduced therein. Press to mold the product according to the mold shape.

(Iii) Clamp closing step

When the mold assembly 20 continues to reach the end of the guide rail 30 lower portion 30c, the height of the opening / closing conductor 50 also falls to the lowest level, and thus the clamp 40 is caused by its own weight. Comes down and is caught in the locking pin 25 is locked. Therefore, in this state, even if the internal pressure of the mold is applied, the upper mold frame 22 is prevented from being lifted by the clamp 40 being locked. (See Fig. 3 (g) and Fig. 4 (g))

(Ⅷ) mold pressing step

This step is, as shown in Figure 3 (f) and 4 (f), when the mold frame assembly 20 is out of the guide rail 30, the push wheel 60 disposed next to it When passing through the lower portion of the, at this time, the upper surface of the upper mold 22 of the mold assembly 20 is pressed by the push wheel 60 to further pressurize the upper mold 22. It is surely done.

Thereafter, the mold base assembly 20 continues to rotate as the rotating base rotates, and when it reaches near the beginning of the guide rail 30, the manufacturing step is repeatedly performed from the preparation step described above. This enables continuous product molding production.
