Description

Molded product double-stage down-slurry automatic molding machine and manufacturing method for manufacturing molded product (1)

The present invention relates to a double-stage down-slurry automatic molding machine for molding products and a manufacturing method for manufacturing the molded product, in particular to a molding product capable of increasing the thickness of the molded product and the surface of the molded product. A molding machine and a method of manufacturing a molded product.

According to the plastic products made of plastic materials, it is easy to release toxins, which cause serious pollution to the environment, difficult to recycle and reuse, or difficult to recycle and recycle, and the cost of recycling is so large, etc. Global environmental protection has caused serious harm. In today's era of high environmental awareness, the search for non-toxic, easy-to-recycle materials has become the mainstream of research and practical applications.

At present, it has been developed to use a pulp fiber material and/or a plant fiber material as a slurry material, and the slurry is adhered by a suction mold, and then the product is manufactured by hot pressing and setting technology, and is a "plastic product". The distinction is generally referred to as "molded products." Molded products have the advantages of easy recycling, re-manufacture and reuse, and are in line with the trend of environmental protection and energy conservation and carbon reduction. Therefore, they are quickly accepted by the business community and the general public, and molded products are often seen, for example, bowls, plates, Cup lids, packaging materials, shock absorbers, mats, etc. - and other products are gradually adopted.

Molded products must be manufactured by "sucking and shaping" and "hot pressing". Among them, "sucking and shaping" is immersed in a slurry tank filled with slurry by a suction mold. A suction device vacuum-applies the slurry in the slurry tank through the suction mold to form a "binder layer" on the mold surface of the suction mold, and when the suction mold rises out of the pulp box, it continues The suctioning action gradually dehumidifies the green layer, and then the suction mold rises together with the blank layer and is pressed to form a blank layer by a cold compression mold, so that the slurry layer reduces humidity and simultaneously shapes It is an "original product", and then the suction mold absorbs the original embryo and leaves the cold pressing mold to complete the operation of suction molding, and then performs the "hot pressing" operation, which is sucked by the hot pressing mold. After the slurry shaping, the blank layer is subjected to a hot pressing setting operation, so that the original layer of the raw material is dried and shaped into a finished product of the molded product.

The present inventors specialize in the manufacture of molded products, and through the experience of prolonged contact with molded products, it has been found that the following defects exist in the manufacture of molded products:

1. In the traditional manufacture of molded products, the suction mold can only cover the single layer of the blank layer on the mold surface, and the layer of the blank cannot be stacked in multiple layers, so the thickness cannot be increased, resulting in poor suspension effect, generally only applicable. For small products (such as bowls, plates, lids, etc.) that have a smoother appearance and need not be too thick in thickness, if you want to make a molded product with a thicker thickness and better shock absorption effect (for example, it has better shock absorption effect). Packaging materials), traditional manufacturing methods are still difficult to achieve.

2. There is a non-excellent surface on the surface, resulting in a low sense of value. Conventional molded products will obviously have two kinds of surfaces on one side and non-excellent on the other side, which is suitable for packaging non-excellent goods (such as packaged eggs), but if it is used for packaging value When a product with a higher degree (such as a mobile phone) has a "non-excellent side" in the packaging material of the molded product, the visual perception is not good, and the value of the overall product is lowered.
