Finally, the thick blank product is turned to be received by a hot pressing upper and lower molds for being hot pressed into a molded product.

Description

Automatic molding machine for double-down suction of molded products and manufacturing method for manufacturing molded products (1)

The present invention relates to a double-pumping automatic molding machine for molding products and a manufacturing method for manufacturing the same, and more particularly to a double-pumping automatic molding product that can increase the thickness and thickness of the molded product. Molding machine and manufacturing method for manufacturing molded products.

According to the fact, plastic products made of plastic materials can easily release toxins and cause serious pollution to the environment, it is difficult to recycle and reuse, or it is difficult to recycle and decompose, and the cost of recycling is huge. Global environmental protection is causing serious harm. In the current era of high environmental awareness, finding non-toxic and easy to recycle materials has become the mainstream in research and practical applications.

At present, there have been developed products that use pulp fiber material and / or plant fiber material to be mixed and beaten as pulp material, and the slurry is adhered to the slurry through a suction mold, and then manufactured by hot pressing molding technology. The distinction is generally called "molded products". Molded products have the advantages of easy recycling, remanufacturing and reuse, and are in line with the trend of environmental protection and reuse and energy conservation and carbon reduction. Therefore, they are quickly accepted by the industrial and commercial industry and the general public and are willing to adopt. Molded products are often visible, such as bowls, plates, Cup lids, packaging materials, shock-absorbing materials, cushioning materials, etc.-are gradually being used.

The manufacturing of molded products must go through two operations, "suction molding" and "hot pressing". Among them, "suction molding" is lowered by a suction mold and immersed in a slurry tank filled with slurry, and then by A suction device vacuum suctions the slurry in the slurry tank through the slurry mold, so that a "blank layer" is formed on the mold surface of the slurry mold. When the slurry mold rises and leaves the slurry tank, The suction effect gradually dehumidifies the material layer, and then the suction mold rises together with the material layer and presses the material layer with a cold pressing mold to squeeze the material layer to reduce the humidity of the slurry layer and shape at the same time. It is a "primitive product", and then the suction mold absorbs the primary product and leaves the cold pressing mold to complete the suction forming operation, and then performs the "hot pressing setting" operation, which is performed by the hot pressing mold. After the shape of the raw material layer is hot-pressed, the original material layer is dried and shaped into the finished product of the molded product.

The inventor is specialized in the manufacture of molded products. After experience of contacting molded products for a long time, I found that the following defects exist in the manufacturing of molded products:

1. In the traditional manufacturing of molded products, the suction mold can only cover the blank layer on the mold surface at one time. The blank layer cannot be stacked in multiple layers, so the thickness cannot be increased, resulting in poor shock absorption. Generally, it is only applicable. For small products (such as bowls, plates, cup lids, etc.) that are smooth in appearance and do not need to be too thick, if you want to make thicker products with better shock absorption (for example, those with better shock absorption) Packaging materials), traditional manufacturing methods are still difficult to achieve.

2. There are non-optimal surfaces on the surface, resulting in low value. It is known that there are two kinds of surfaces on one side: superior surface on the other side and non-optimal surface on the other side. It is suitable for packaging non-high value products (such as egg packaging), but if it is used for packaging value For high-quality products (such as mobile phones), the presence of "non-optimal surface" in the packaging material of molded products will cause poor visual perception and will reduce the overall product value.

Because the conventional molded products have difficulty in increasing the thickness and the existing defects of a non-optimal surface, the use of the molded products is greatly restricted in their use and cannot be directly used for packaging high-value products.

In view of the above shortcomings, the present inventor has conceived research and development improvements, and hopes to provide an automatic molding machine with a completely new structure and a manufacturing method for manufacturing the molded products to solve the above shortcomings. After a long period of effort, the present invention produce.

After the above steps are carried out one by one, the expected molded product can be manufactured and molded, and the thickness of the molded product manufactured is significantly increased by two times. Therefore, the present invention has the following excellent effects in manufacturing and use;

1. The present invention discloses that the lower suction mold 10 enters the slurry tank 20 for suction twice to form a first blank layer and a second blank layer, respectively, and the cold pressing upper mold 31 first receives the first blank layer. A blank layer is extruded with the cold-pressing lower mold 32, and then the second blank layer is co-extruded into a thick blank. Finally, the thick blank is transferred to the hot-pressed upper and lower molds 41 and 42 and received. Hot press molding is a molded product. Such a structural composition and manufacturing method are not found in any conventional molding product manufacturing machine.

2. The thick embryo formed in the manufacturing process of the present invention is double-sucked into the pulp box 20 by the lower suction mold 10 to suck the slurry, so as to form the first and second blank layers, respectively. The cold-pressed upper die 31 first receives the first blank material layer and extrudes it with the cold-pressed lower die 32, and then accepts the second blank material layer to be co-extruded to a thick embryo with a double thickness. Because the outer surface of the thick embryo is a superior surface formed by the lower suction mold 10 and the cold-pressed upper mold 31 being tightly squeezed, the hot-pressed upper and lower molds 41 and 42 are hot-pressed and shaped. The outer surface of the molded product is the superior surface, which is enough to enhance the overall value of the packaged goods.

3. The thick embryo formed in the manufacturing process of the present invention is finally transferred to the hot-pressed upper and lower molds 41 and 42 to receive and perform the hot-press setting of the thick embryo. If the hot-pressing time must be longer, the heat The composition of the upper and lower molds 41 and 42 can also be set to have two or more groups on the same side to perform two or more stages of hot pressing setting work on the same thick embryo, thereby reducing the overall hot pressing work and enabling the mold The surface of plastic products is more superior.

To sum up, the present invention does have absolute novelty and practical progress. Therefore, it is necessary to apply for an invention patent in accordance with the law. I urge you to grant the patent in this case as soon as possible after examination.

The finished product of the molded product stays. The following steps are followed: (1). Start the external power mechanism connected to the lower suction mold, drive the lower suction mold to descend and immerse in the slurry in the slurry tank, and pass The connected first pumping device starts sucking slurry to form a first blank layer on the die surface of the lower suction mold; (2). When the suction time is up, the lower suction mold adsorbs the first The blank layer is moved up from the pulp surface and returned to the original position. During the process, the first pumping device continues to suck, dehydrating and dehumidifying the first blank layer; (3). Start the connection of the lower suction mold External power mechanism drives the lower suction mold to attract The first blank layer rises, enters the cold-pressed upper mold and closes the mold to squeeze the first blank, and then the second pumping device connected to the cold-pressed upper mold starts the suction to attract the first blank. Material layer, at the same time, the first suction device connected to the lower suction mold stops the suction effect, and converts to a blowing effect, so that the first blank material layer and the lower suction mold are separated; ； (4). Start the The cold pressing upper die is connected with a power mechanism to drive the cold pressing upper die to adsorb the first blank layer and move laterally along the guide rail directly above the cold pressing upper die, and at the same time, the hot pressing upper die will move along The guide rail moves synchronously with the cold-pressed upper mold; at the same time, the lower suction mold is lowered and immersed in the slurry of the slurry tank again, and sucks the slurry again through the first pumping device connected to the bottom. A second blank layer is formed on the die surface of the suction die; (5). The cold pressing die starts the suction effect through the third pumping device connected, and simultaneously activates the external power connected by the cold pressing die. A mechanism for driving the cold-pressed lower die to rise into the cold-pressed upper die to close the die to squeeze the first embryo The layer is dewatered, and then the third pumping device connected to the cold pressing die stops the suction function, and is converted into a blowing function, so that the first blank layer is separated from the cold pressing die, and the cold pressing die is connected. The second pumping device still starts the suction effect to continuously adsorb the first blank layer; at the same time, the lower suction mold also adsorbs the second blank layer and moves away from the pulp surface to return to the original position. And the first pumping device continuously sucks, so that the second blank layer is dehydrated and dehumidified; (6). The cold-pressing die is connected to the cold-pressing die to drive the cold-pressing die down and return to position, and the The cold-pressed upper mold sucks the first blank layer and moves in the reverse direction along the guide rail to return directly above the lower suction mold. At the same time, the hot-pressed upper mold follows the cold-pressed upper mold and moves backward along the guide rail. (7). Outside the lower suction mold is connected, the power mechanism drives the lower suction mold to adsorb the second blank material layer to rise and enter the cold pressing upper mold to close the mold, at this time the first blank material Both the layer and the second blank layer are co-extruded and formed into a thick layer between the cold-pressed upper die and the lower suction die. The thickness of the thick embryo product is twice that of the first or second embryo material layer. During the process, the second pumping device connected to the cold pressing upper mold continues to suck to absorb The thick embryo, at the same time, the first suction device connected to the lower suction mold stops the suction effect, and is converted into a blowing effect, so that the thick embryo and the lower suction mold are separated; (8). The cold In addition to the connection of the upper die, the power mechanism drives the cold upper die to adsorb the thick blank and move it along the guide rail to directly over the hot lower die.

Start the external power mechanism connected to the hot-pressed lower mold, drive the hot-pressed lower mold to adsorb the thick embryo and rise into the hot-pressed upper mold, and then the thick-embedded product is between the heat. The upper mold and the lower mold are pressed, so the hot mold and the lower mold are used to perform hot pressing on the thick blank for a period of time, so that the thick blank is completely dried into a molded product. (13). As soon as the hot press setting operation time is up, the fourth pumping device connected to the hot press upper mold starts the suction effect to attract the molded product, and at the same time, the fifth pump connected to the hot press lower mold. The device initiates a blowing action to disengage the molded product from the hot-pressed mold, Then the hot-pressing lower die moves back into position; then the power mechanism connected to the hot-pressing upper die drives the hot-pressing upper die to move backward along the guide rail directly above the receiving tray, while the cold The pressing die also moves synchronously along the guide rail directly above the hot pressing die; (14). Start the external power mechanism connected to the receiving tray to drive the receiving tray to rise from the hot pressing die. Once the drop distance stays at the specified position, the drop distance can just be used to smoothly drop the molded product without affecting the subsequent movement of the hot press upper die, and then the fourth pumping device connected to the hot press upper die Stop the suction effect, convert to blowing effect, so that the molded product is separated from the hot pressing upper mold, so the finished product of the molded product is blown off to stay on the platform of the receiving tray; (15). The hot press upper die is connected with a power mechanism to drive the hot press upper die to move laterally along the guide rail directly above the hot press lower die, and at the same time, the cold press upper die also moves synchronously along the guide rail 11 to The lower suction mold is directly above; at the same time, the outside of the receiving tray is connected Power means connected to drive the tray fall back into place, thus the finished molded products can be taken from the set, to complete a cycle. The method for manufacturing a molded product by using a two-shot suction automatic molding machine for a molded product as described in item 2 of the scope of patent application, wherein the action of removing the finished product of the molded product from the receiving tray can be borrowed.
