Description

Non-woven product forming device and manufacturing method

The present invention relates to a molding device and manufacturing method of a non-woven product, in particular to a molding device and a manufacturing method of a non-woven product whose molding die can perform hot pressing.

According to "non-woven products", most fiber materials are collected and laminated, and then needled, carded, heat-melted, baked, cold-pressed and other steps are selectively used to directly combine the fiber materials to the expected density and thickness. The block product. There are many kinds of non-woven products in daily life, such as non-woven vegetable cloth on the market, toilet brush body, seat cushion, cushion or sleeping pad, sound-absorbing material, sound insulation material, interior material, bedding, etc. -Etc. are all non-woven products.

There are many manufacturing methods for "non-woven products". One of the conventional manufacturing methods of non-woven products is to pave the fiber materials and stack them, and then cut them into blocks of appropriate size after appropriate shaped fillings. The fiber masses are sequentially sent into a heating oven to be fully heated, so that the fibers inside the fiber masses are bonded and softened by heat melting, and finally the softened fiber masses are sent into In a cold forming mold, by pressing the upper and lower mold surfaces, the fiber mass is directly formed into a non-woven product of the expected shape and density. General automotive interior sound-absorbing materials, sound insulation materials, interior materials, bedding, etc. They are all manufactured using this kind of cold forming method.

The conventional cold press molding manufacturing method mainly assumes that after the fiber block is fully heated, the fibers inside the fiber block will be bonded and joined by heat, and the overall fiber block will appear softened. It is equivalent to the thermoplastic material being heated and completely softened. Therefore, after the softened fibrous mass enters the cold forming mold, as long as the upper and lower mold surfaces are shaped, the molded product can be pressed and the original thickness A relatively large fiber block can also be compressed into a finished product (such as a floor mat) with a relatively small thickness. The principle is that when the fiber block is originally stacked, the fibers of the fiber block have a large cross gap, so It is high-thickness and low-density. After heat drying, all fibers are expected to be melted, bonded and softened. After being pressed into the cold forming mold, all the fibers can be pasted into the desired non-woven product. In the process, the large gaps between the fibers disappear due to extrusion, and the hardness and strength can be improved due to the bonding between the fibers, so the final non-woven product is low thickness and high density.

The above-mentioned conventional cold press forming method is ideal. When the expected thickness of the product is not very thick and the shape is mostly straight (without a lot of bending), the conventional cold press forming method is still called foot compress , But when the molded product has a considerable thickness or the shape has many bends, the conventional manufacturing method of cold press molding often has defects that cannot be molded and the bends are easily broken after molding. The reason for the failure of forming and easy collapse of the bending part is mainly due to the fact that the fiber mass is too thick, or the heating time is insufficient, or the heating temperature is when the fiber mass is baked in the heating oven. When it is not enough, the fiber mass cannot be heated uniformly inside and outside, especially the internal fibers cannot be thermally fused and softened, so sometimes the appearance may seem to be softened, but there are still parts of the inside that are not fully softened by heating. ; Furthermore, after the bake fiber mass is sent out of the heating oven, the temperature begins to decrease because it is no longer heated, and then enters the cold forming mold and is pressed by the upper and lower mold surfaces. 、The lower mold surface is usually set to room temperature or cold water to cool down (the purpose is to cool the product after molding), so the fiber mass is quickly cooled. At this time, if the fiber mass is partially softened inside, Even though it is strongly pressed by the cold forming mold, the unsoftened fiber inside retains the expansion elasticity, resulting in a situation where the shape cannot be reliably formed, or the bending is caused by the stress of the expansion elasticity after reluctance. It is easy to collapse and malfunction.

It can be seen from the above description that when the conventional manufacturing method of cold press molding is actually implemented, as long as the fiber mass is not softened by heat uniformly inside and outside, it is easy to produce defective products. For this reason, the manufacturer has to increase the heating time in the heating oven or increase the heating temperature to ensure that the fibrous masses are all softened before sending out the heating oven, but this is a serious lack of derived heat energy being consumed in large quantities, except In addition to unfavorable environmental protection requirements, there is also the lack of raising manufacturing costs.

In view of the deficiencies derived from the conventional cold-pressing manufacturing method for non-woven products, the inventors conceived that since in the conventional cold-pressing manufacturing method, the fibrous block is not sent out of the heating oven. After being heated again, and therefore the above-mentioned defects may be derived, if it can be designed so that the fibrous block can still be subjected to penetrating heating after entering the forming mold, so as to ensure that the fibrous block is completely softened and formed For non-woven products, the inventor of the present invention developed and designed a molding device and manufacturing method for non-woven products that can be thermoformed. After long-term R&D, design and multiple tests, the present invention was finally produced.
