Paper-plastic molding machine structure and paper-plastic finished product

The present invention relates to a paper-plastic forming machine and a paper-plastic product manufactured using the paper-forming machine, in particular to a pre-compression of a wet paper embryo with high water content to accelerate the subsequent hot press forming efficiency of the wet paper embryo. The paper-plastic molding machine structure and the paper-plastic finished product have a high surface smoothness on both the inner and outer surfaces of the paper-plastic finished product.

The sponge or foam that is traditionally used for protection and shockproofing on the inner or outer packaging of the product is gradually replaced by a pulp molded product of pulp molding. Pulp molded products (or paper-plastic products) are made from pulp as raw materials, which are sucked and molded by a molding die. The finished products can be recycled and remanufactured, so they are in line with the trend of energy saving and carbon reduction.

The conventional machine equipment used to manufacture paper and plastic products is divided into two separate working machines, a molding machine and a shaping machine. The machines are not connected to each other, and the continuous continuous operation cannot be maintained in the form of an automatic production line. All need to transfer paper and plastic semi-finished products by manual means. The molding machine performs a slurrying step and a hot pressing step. The slurrying step is to take the pulp out of the pulp tank by a plurality of molds; the hot pressing step is to heat and press the plurality of molds to reduce the humidity of the pulp in the mold and obtain a pulp semi-finished product by a hot press shaping process. The receiver then cuts the excess portion of the semi-finished pulp product by the shaping machine to complete the paper-plastic product.

Second, conventional molding machines only reduce the humidity contained in the pulp by a hot pressing step. After the mold completes the pulping step of the pulp, the pulp in the mold contains a high proportion of moisture (more than 50% of the total weight), and it takes a lot of time to remove the moisture in the pulp in the subsequent molding process, such as a hot pressing step. The process of removing the moisture of the pulp takes about 160 seconds to obtain each semi-finished product/finished product. This is quite time consuming in the process of mass production of paper and plastic products, making the productivity of paper and plastic products inefficient. Moreover, if the strength of the hot pressing between the molds is increased in order to quickly remove the moisture in the pulp, the semi-finished pulp may not be able to withstand the pressure between the molds and be broken, and overall, the production efficiency is poor and it is difficult to meet economic benefits.

Therefore, it is urgent to shorten the time of the hot pressing step in the paper-plastic process and maintain the integrity of the semi-finished/finished product of the pulp.

In order to solve the above-mentioned conventional mechanical equipment, the hot pressing step is too time-consuming to relatively lengthen the overall processing time, resulting in a relatively slow working speed and relatively low output, and even more, the problem of fragmentation of the semi-finished pulp. The purpose is to provide a paper-plastic forming machine structure for accelerating the formation speed of the paper-plastic product, using the first set of upper and lower molds to perform slight pressing in the slurry-removing step, and discharging a certain amount of water before the hot pressing step, thereby avoiding During the hot pressing process, the semi-finished product with high water content is rapidly heated and pressurized to produce the fragmentation of the semi-finished product, so that the pulp fibers in the semi-finished product of the pulp are more dense, and then heated and pressed by the second group of upper and lower molds to simultaneously press each other to achieve rapid The effect of drying shortens the time it takes for the pulp to dry, so it can effectively increase the efficiency and increase the output.

Similarly, the vacuum adsorption device 50 is in fluid communication with the through holes 34 and is exhausted by the through holes 34, and the water in the molds is respectively sucked through the through holes 34. Half of the finished product 101 is discharged by the water vapor generated by the heat.

The through holes 34 are formed during the process of forming the mold, such as by wire cutting, laser processing, grinding, or electric discharge machining. In various embodiments, the through holes 34 may be integrally formed from a corresponding mold during the metal casting/sintering process during mold making.

Referring to FIG. 1 , FIG. 2 and FIG. 3 , the second upper mold 31 is a convex mold, that is, the second upper mold 31 has a convex portion 311 at the center, and the second lower mold 32 is A groove-shaped mold, that is, a second recess 32 has a recess 321 in the center.

Taking the slurry 100 by the flipping slurry device 70 and fishing with the first lower mold 23 The difference between the modes of the slurry collector 100 is that the conditions in which the fibers in the slurry 100 are deposited on the bottom of the mold are different. The former causes the fibers near the first mesh 231 to be relatively short due to the suction force, that is, the shorter fibers in the slurry 100 are adsorbed and deposited on the bottom of the inverted mold, so that the corners of the subsequent paper-plastic products are presented. A more aesthetically pleasing right angle state; while the latter causes the fibers in the slurry 100 to be only subjected to gravity deposition due to the fishing method, the longer fibers in the slurry 100 are deposited on the bottom of the mold, causing the subsequent corners of the finished paper product to be presented. Less aesthetically rounded or obtuse angles.
