Description
[ technical field ] A method for producing a semiconductor device
The invention relates to an automatic pulp-sucking forming machine for paper-plastic products and a manufacturing method thereof, in particular to an automatic reciprocating pulp-sucking forming machine for paper-plastic products and a manufacturing method thereof, which can improve the manufacturing speed, shorten the production period and reduce the manufacturing cost.
[ background of the invention ]
At present, there has been developed a product manufactured by mixing and beating pulp fiber materials and/or plant fiber materials into pulp materials, sucking pulp by a pulp sucking mold, attaching the pulp, and then performing a hot press molding technique, which is generally called as "paper-plastic product" or "molded product" or "pulp molded product" for distinguishing from "plastic product", and is called as "paper-plastic product" in this specification. The paper-plastic product has the advantage of easy recovery, remanufacture and reuse, accords with the trend of environmental protection, reuse, energy saving and carbon reduction, is rapidly accepted by the industry and the public and is willing to adopt, and the paper-plastic product is often visible, such as: the products such as bowls, plates, cup covers, packaging materials, shock absorbing materials, cushion materials and the like are gradually adopted, and the products can be large and small in volume and are various.
In the conventional process for manufacturing paper and plastic products, a plurality of operations, including "pulp suction forming", "hot press forming", "product transferring" and "end finishing", are basically performed, wherein the two operations, i.e., "pulp suction forming" and "hot press forming", are the main processes for manufacturing and forming the paper and plastic products, and are generally performed by a "pulp suction automatic forming machine", and the two operations, i.e., "product transferring" and "end finishing", are the processes for completing the manufacturing and forming of the paper and plastic products, and then further collecting and transferring the products to end finishing (e.g., trimming, inspecting, and packaging). Among them, the "slurry-sucking automatic forming machine" is the most important hand for manufacturing and forming paper-plastic products, and a good "slurry-sucking automatic forming machine" is required and a proper manufacturing method (process step) is matched to manufacture and form a good paper-plastic product.
The conventional slurry sucking automatic forming machine has many kinds of structural components and its matched manufacturing method is also very popular. The pulp-sucking automatic forming machine and the manufacturing method adopted for manufacturing the paper-plastic product with the relatively large forming volume are different from those adopted for manufacturing the paper-plastic product with the relatively small forming volume, because the two paper-plastic products with the relatively large and relatively small volumes are different in pulp sucking mode and time, extrusion mode and time, hot-press forming mode and time, and more simply, the production periods of the two paper-plastic products are different, so that the pulp-sucking automatic forming machine and the manufacturing method can not be integrally applied absolutely, and the pulp-sucking automatic forming machine and the manufacturing method can not be properly adjusted according to the different paper-plastic products to be manufactured and formed.
The applicant is specialized in the design and manufacture of various automatic slurry-sucking molding machines and the design and manufacture of various paper-plastic products, and finds that the conventional various automatic slurry-sucking molding machines have the defect of wasting production cycle when being applied to manufacturing light, small and thin paper-plastic products through the experience of contacting various automatic slurry-sucking molding machines and various paper-plastic products for a long time. The reason is that the prior various pulp-sucking automatic molding machines and manufacturing methods are designed for molding paper-plastic products with more than medium thickness, and some paper-plastic products can be doubled in thickness, so when the conventional pulp-sucking automatic molding machine is used for manufacturing paper-plastic products with light and thin thickness, the pulp-sucking mode and time, the extrusion mode and time, the hot-press molding mode and time are excessive, the accumulated secondary production period cannot be correspondingly shortened, and the manufacturing cost cannot be relatively reduced.
