Description
[ technical field ] A method for producing a semiconductor device
The present invention relates to a forming device and a manufacturing method of a non-woven fabric product, and more particularly to a forming device and a manufacturing method of a non-woven fabric product, in which a forming mold can perform a hot press forming function.
[ background of the invention ]
The non-woven fabric product is produced by using most fiber materials, collecting and laminating, and selectively using various steps of needle punching, carding, hot melting, baking, cold pressing and the like to directly combine the fiber materials into a block product with expected density and thickness. In daily life, various non-woven fabric products are available, such as commercially available non-woven fabric cloth for dishcloth, a toilet brush body, a seat cushion, a back cushion or a sleeping mat, and sound absorbers, sound insulators, interior materials, bedding and the like which are installed in automobiles.
The conventional non-woven fabric product is produced by laying and stacking fiber material, adding proper material, cutting into blocks of proper size, heating in a heating oven to soften the fiber inside the blocks, cold pressing the softened blocks in a cold press mold to form the non-woven fabric product with required shape and density.
The conventional cold press molding method is mainly to assume that after the fiber block is fully heated, the fibers inside the fiber block are bonded and jointed by hot melting, and the whole fiber block is softened as if the thermoplastic material is heated and completely softened, so that after the softened fiber block enters the cold press molding die, the molded product can be pressed as long as the upper and lower die surfaces are in the same shape, and the original fiber block with relatively large thickness can be pressed into a finished product (such as a floor mat) with relatively small thickness, and the principle is that when the fiber block is originally stacked, the fibers of the fiber block have large cross gaps, so the fiber block has high thickness and low density, and then after the hot drying, all the fibers are expected to be heated, bonded and softened, and then the fiber block is pressed in the cold press molding die, all the fibers can be jointed to form the expected non-woven fabric product, the large gaps among the fibers disappear due to extrusion in the process, and the hardness and the strength of the fibers can be improved due to the jointing, so that the final non-woven fabric product has low thickness and high density.
The conventional cold press forming method is ideal, and is said to be sufficient for use when the thickness of the product to be formed is not very thick and the shape is mostly straight (not having much bending), but when the thickness of the product to be formed is quite large or the shape is much bending, the conventional cold press forming method often has the defects that the forming cannot be performed and the bent part is easy to break and break after forming. The reason why the fiber block cannot be formed and the bent part is easy to break is mainly that when the fiber block is baked by the heating baking oven, if the fiber block is too thick, or the heating time is insufficient, or the heating temperature is insufficient, the inside and the outside of the fiber block cannot be heated uniformly, especially the fibers inside cannot be melted, adhered and softened, so that the appearance is observed to be softened sometimes, but the inside of the fiber block is still partially in a state of being insufficiently heated and softened; furthermore, after the fiber block body is sent out of the heating baking oven, the temperature begins to be reduced because the fiber block body is not heated any more, then the fiber block body enters the cold-pressing forming die to be pressed by the upper die surface and the lower die surface in a fitting manner, because the upper die surface and the lower die surface are usually set to be normal temperature or set to be cold water for cooling (aiming at cooling the formed product), the fiber block body is cooled more quickly, at the moment, if the fiber block body has parts which are not softened in time, even if the fiber block body is pressed by the cold-pressing forming die in a strong manner, the situation that the fiber block body cannot be formed really due to the fact that the fibers which are not softened in the fiber block body are kept with expansion elasticity is generated, or the situation that the bending part is relatively easy to break down due to the stress action of the expansion elasticity after the fiber block body is formed in a weak manner is generated.
As is clear from the above description, in the conventional cold press molding method, a defective product is likely to occur if the fibrous mass is not softened by heat inside and outside the mass. Therefore, manufacturers only need to increase the heating time or temperature in the heating and baking oven to take the fiber block bodies to be totally softened and then send the fiber block bodies out of the heating and baking oven, but the serious defect that the derived heat energy is consumed in large quantity is that the manufacturing cost is increased besides the adverse environmental protection requirement.
The above problems clearly remain to be improved.

(1) the upper forming die and the upper base plate are pushed by the upper pushing piece to descend and stay at a preset position, and meanwhile, the lower forming die and the lower base plate stay at a preset position below the upper forming die and the upper base plate, and a softened fiber block is pushed by a conveyor to be placed on the lower forming die and the lower base plate;
(2) the lower forming die supports a softened fiber block body to be pushed by the lower pushing piece to rise and is matched with the upper forming die, so that the softened fiber block body is pressed and formed into a non-woven fabric product with an expected shape by the upper forming die and the lower forming die together;
(3) when the forming time is up, the air pumping machine connected with the outer end of the upper joint continues to perform pumping action to adsorb the non-woven fabric product on the upper forming surface of the upper forming die, and meanwhile, the air pumping machine connected with the outer end of the lower joint stops acting, and the non-woven fabric product continues to be cooled in the process;
(4) the upper pushing piece drives the upper forming die to suck the non-woven fabric product to rise to the original high point for staying, an external mechanical arm stretches into the upper forming die to clamp the non-woven fabric product, and meanwhile, an air pumping machine connected to the outer end of the upper joint stops pumping to change the pumping action into a blowing action, blows the non-woven fabric product away from the upper forming surface of the upper forming die and is taken away from a collection set by the mechanical arm; when the upper forming die rises, the lower pushing part also drives the lower forming die to descend to the original preset position for stopping, and the next stroke is waited for.
