Description

Paper-plastic product automatic forming machine and manufacturing method thereof

The invention relates to an automatic forming machine for paper-plastic products and its manufacturing method, especially to an automatic forming machine for pulp-absorbing paper-plastic products and a manufacturing method that can increase the manufacturing speed, shorten the production cycle, and reduce the manufacturing cost.

By the way, environmental protection is the goal pursued by all countries in the world. In order to greatly reduce the harm of plastic material products to the environment, there have been developments in which pulp fiber materials and/or plant fiber materials are mixed and beaten as pulp raw materials, and then through a pulp suction In order to distinguish from "plastic products", the products made by absorbing slurry and attaching slurry to the mold, and then undergoing hot-pressing shaping technology are generally called "paper-plastic products", or also called "molded products". ” or “pulp molded products” are referred to as “paper molded products” in this manual. Paper-plastic products have the advantage of being easy to recycle, remanufacture and reuse, and conform to the trend of environmental protection, reuse, energy saving and carbon reduction. Therefore, they are quickly accepted and adopted by the industrial and commercial circles and the general public. Paper-plastic products are often seen such as: bowls, plates, Cup lids, packaging materials, shock-absorbing materials, cushion materials, etc. --- products are gradually being used. It can be said that paper and plastic products vary in size, and there are all kinds of them.

The manufacturing process of conventional paper and plastic products basically has to go through various operations such as "suction forming", "hot pressing setting", "finished product transfer" and "end finishing". Among them, "suction forming" and "hot pressing setting" These two steps are the main manufacturing and molding processes of paper-plastic products. Generally, they must be completed by an "automatic paper-plastic product forming machine". , and further collect and transfer the finished products to the end-finishing (eg trimming, inspection, packaging) process. Therefore, it can be seen that "paper-plastic products automatic forming machine" is an important driving force for the completion of paper-plastic products. It is necessary to have a good "automatic paper-plastic product forming machine" and match with appropriate manufacturing methods (process steps) to manufacture and form excellent paper-plastic products.

The known automatic molding machines for paper and plastic products have many kinds of structures, and there are many matching manufacturing methods. To put it simply, the automatic molding machine and manufacturing method used to manufacture paper-plastic products with a relatively large molding volume (such as 3C product shock absorbers) must be the same as the manufacturing of paper-plastic products with a relatively small molding volume ( For example, shallow dish) are used differently because the volume is relatively large and the volume is relatively small. Two kinds of paper-plastic products, in terms of pulp suction method and suction time, extrusion dehydration method and extrusion dehydration time, hot pressing molding method and The hot pressing molding time will be different. To put it simply, the production cycle of the two kinds of paper-plastic products must be different. Therefore, the automatic molding machine and manufacturing method of paper-plastic products cannot be applied in one package, and must be manufactured according to the desired shape. Make appropriate adjustments for different paper and plastic products.

The thickness of the plastic product can be doubled. Therefore, when using the conventional paper-plastic product automatic forming machine to manufacture light and thin paper-plastic products, the suction method and time, the extrusion dehydration method and time, and the hot-press molding method There will be too much time and time, and the accumulation of each production cycle will not be shortened accordingly, resulting in the relative inability to reduce the manufacturing cost and the lack of waste of energy.

According to the structure and composition of the above-mentioned paper-plastic product automatic forming machine 1, the present invention also seeks a manufacturing method of a paper-plastic product automatic forming machine, which uses the above-mentioned paper-plastic product automatic forming machine 1 and then adopts the following steps: as shown in Figure 3 , at the beginning, the slurry suction mold 20 was immersed in the inside of the slurry box 10, and then the first pumping device connected to the slurry suction mold 20 was started to suck slurry to form a slurry on the die surface of the slurry suction mold 20. One blank material layer, it must be emphasized that the mold surface of the slurry suction mold 20 can be configured with a plurality of slurry suction positions, so the plurality of slurry suction positions are all suctioned to form a plurality of blank material layers at the same time.

As shown in Figure 4, when the slurry suction time is up, the support member 21 stretches, pushing the slurry suction mold 20 to absorb the stock layer and leave the pulp box 10 to move upward, during which the first pumping device continues to suck , to gradually dehydrate and dehumidify the blank layer; while the slurry suction mold 20 is rising, the first hot pressing upper mold 30 is also driven by the connected external power mechanism to move laterally along the guide rail 32 into the central space 11, and stop moving at the position corresponding to the slurry suction mold 20, then the slurry suction mold 20 moving upwards absorbs the blank material layer and closes the first hot-pressing upper mold 30 to extrude the blank material layer for dehydration. During the process, the second pumping device connected to the first hot-pressing upper mold 30 also activates the suction function to help gradually dehydrate and dehumidify the blank layer. When the short mold closing and extrusion time is up, the blank layer has Dehumidification becomes an initial product, and then the first pumping device connected to the slurry suction mold 20 stops the suction function, and converts into a blowing (air supply) effect to separate from the initial product, and the first hot-pressed upper mold The second pumping device connected to 30 still carries out the suction function to absorb the embryonic product. It must be emphasized that in the process shown in Figure 4, the first hot-pressing upper mold 30 does not carry out hot-pressing. The role is to act as a cold die.

As shown in Figure 5, the first hot-pressing upper mold 30 then absorbs the blank product and is driven by the power mechanism outside the connection to move in the opposite direction along the guide rail 32 into the first side space 31 to return, and Stop moving at the position corresponding to the first hot-pressing lower die 40, and then the first hot-pressing lower die 40 is pushed up by the power mechanism outside the connection to close the mold with the first hot-pressing upper die 30. The initial product is between the first hot-pressing upper die 30 and the first hot-pressing lower die 40, and then the first hot-pressing upper die 30 and the first hot-pressing lower die 40 work together to form the first embryo. The product is hot-pressed and shaped for a period of time, so that the preliminary product is completely dried into a paper-plastic product. During the process, the second and third pumping devices both start suction to cause a heat cycle, so that the preliminary product can be dried as quickly as possible. Paper and plastic products; while the first hot-pressing upper mold 30 absorbs the initial product and returns to its position in reverse, the slurry suction mold 20 stops the blowing (air supply) function, and is driven by the support member 21 to descend into the pulp box Return to the zero (initial) position within 10, and at the same time, the first pumping device connected to the slurry suction mold 20 starts the suction action again to carry out the second round of slurry suction, so that the mold surface of the slurry suction mold 20 is again Form a blank material layer; it must be emphasized that, while the first hot-pressing upper mold 30 and the first hot-pressing lower mold 40 are performing hot-pressing and setting operations on the initial blank, the slurry-suction mold 20 absorbs slurry again to form a The blank layer belongs to another (second) production cycle, that is, at this time, the hot-pressing and setting operation of the first production cycle is still in progress, and the suction of the second production cycle has already started.

As shown in Figure 6, when the time for hot-pressing and setting work arrives, the initial product has been dried into a paper-plastic product, and then the second pumping device connected to the first hot-pressing upper mold 30 stops the suction function and switches to blowing. (air blowing) function, to disengage with this paper-plastic product, the 3rd pumping device that this first hot-pressing lower die 40 is connected then still carries out suction action to absorb this paper-plastic product, then this first hot-pressing presses down The mold 40 absorbs the paper-plastic product and moves downward; then the slide rail block 74 of the first material receiving mechanism 70 is pushed by the external power mechanism to move along the transverse rail 73, and drives the slide bar 75 to push the Most of the absorbing parts 76 move synchronously, so that the sliding rod 75 part and the plurality of absorbing parts 76 enter the first side space 31 together, and make the plurality of absorbing parts 76 one-to-one right behind each paper-plastic product. Stop, and then the horizontal track 73 is pushed down by the external power mechanism along the straight track 72 for a short distance, so that the absorber 76 stops after touching the paper-plastic product, and the vacuum suction connected to the absorber 76 The mechanism starts the adsorption, and the first hot pressing die 40 is connected The third pumping device stops the suction, so that the paper-plastic product is transferred to be absorbed by the absorber 76; while performing the above-mentioned actions, the actions belonging to the second production cycle are also continued, as shown in Figure 6 , the slurry suction mold 20 absorbs the embryo material layer that is sucked again and moves upward from the pulp box 10, and at the same time, the second hot-pressing upper mold 50 also moves laterally along the guide rail 32 into the central space 11, and the The slurry suction mold 20 closes the mold and extrudes the blank material layer for dehydration. These actions are exactly the same as those performed by the aforementioned first hot-pressing upper mold 30, so they will be described in detail.

As shown in Figure 7, then, the action belonging to the first production cycle is that the transverse rail 73 rises back to its position along the straight rail 72, and the slide rail block 74 moves in reverse along the transverse rail 73, and promptly Drive this slide bar 75 and withdraw from this first side space 31 outsides together with this plurality of absorbers 76 (absorbing most of the paper and plastic products), and have the container of collection usefulness in this plurality of absorbers 76 ( Absorb most of the paper and plastic products) and wait below, so the adsorption member 76 stops the adsorption immediately, so that most of the paper and plastic products enter the container for collection, but the collected part is not within the scope of the present invention, so it will only be described in detail; While performing the above actions, the actions belonging to the second production cycle are also continued. As shown in FIG. 7, the second hot-pressing upper mold 50 absorbs the blank product and moves in the opposite direction along the guide rail 32 into the second side Return to the position in the space 51, and then the second hot-pressing lower mold 60 rises and closes the second hot-pressing upper mold 50, and jointly performs hot-pressing and setting operations on the blanks belonging to the second production cycle to completely dry into a paper sheet. In the process of molding products, the slurry suction mold 20 descends into the pulp box 10 and returns to the zero (initial) position, and immediately performs the third round of slurry suction, so that the mold surface of the slurry suction mold 20 is formed again. One blank material layer; it can be strengthened that when the paper-plastic products belonging to the first production cycle are removed and collected, the hot-pressing and shaping operation belonging to the second production cycle is also in progress, and at the same time the slurry suction of the third production cycle It is also expanded so that the first, second and third production cycles can be carried out simultaneously in order to greatly shorten the production cycle.

As shown in Figure 8, then, the action belonging to the second production cycle is that when the hot-press setting operation time is up, the second hot-press lower mold 60 absorbs the paper-plastic product and moves back to its position, while the second contact The slide rail block 84 of the material mechanism 80 promptly drives the slide bar 85 to push the plurality of absorbing parts 86 to synchronize along the transverse track 83 Move, make this slide bar 85 part and this plurality of absorbing parts 86 enter in this second side space 51 jointly, and make this majority of absorbing parts 86 one-to-one right each paper-plastic product, then this transverse rail 83 along As the straight track 82 descends, the absorber 86 touches the paper-plastic product, then the absorber 86 starts the adsorption action, and the second hot-pressing die 60 stops the suction, so that the paper-plastic product is transferred to Absorbed by the adsorbent 86; while performing the above-mentioned actions, the actions belonging to the third production cycle also continue, as shown in Figure 8, the slurry suction mold 20 absorbs the blank material layer of the third round of slurry suction and leaves The pulp box 10 moves upwards, and at the same time, the first hot-pressing upper mold 30 laterally shifts along the guide rail 32 and enters the central space 11 again, and the slurry suction mold 20 closes and squeezes the blank layer for dehydration. These actions and The above-mentioned first hot-pressing upper mold 30 and second hot-pressing upper mold 50 have performed exactly the same, so it will only be described in detail.

As shown in Figure 9, continuing, the action belonging to the second production cycle is that the transverse rail 83 rises back to its position along the straight rail 82, and at the same time the slide rail block 84 moves in reverse along the transverse rail 83, and that is Drive the slide bar 85 and the plurality of adsorbents 86 (absorbing most of the paper and plastic products) to exit to the outside of the second side space 51, and there are containers for collection under the plurality of adsorbents 86 while in motion. Wait, so immediately this adsorption member 86 stops the adsorption, so that most of the paper and plastic products enter the container for collection, because the collected part does not belong to the scope of the present invention, so it will not be described in detail; while carrying out the above actions, it belongs to the third The actions of the production cycle also continue, as shown in Figure 7, the first hot-pressing upper mold 30 absorbs the initial product and moves in the reverse direction along the guide rail 32 into the first side space 31 to return, and then the first A hot-pressing lower mold 40 rises and closes the first hot-pressing upper mold 30, and jointly performs hot-pressing and setting operations on the initial product belonging to the third production cycle to make a paper-plastic product. During the process, the suction mold 20 Descend again into the pulp box 10 and return to the zero (initial) position, and immediately carry out the fourth round of slurry suction, so that a stock layer is formed again on the mold surface of the slurry suction mold 20; therefore, the description can be strengthened Yes, while the paper and plastic products belonging to the second production cycle are removed and collected, the heat-pressing and setting operation belonging to the third production cycle is also in progress, and at the same time, the pulp suction belonging to the fourth production cycle It also unfolds, so that when the first production cycle has ended, the second, third, and fourth production cycles still exist in sequence and proceed simultaneously. Therefore, due to the convenience of multiple production cycles at the same time, the manufacturing speed can be increased, the production cycle can be shortened, and the manufacturing cost can be reduced.

After the above steps are carried out one by one, the expected paper-plastic products can be manufactured and shaped, and because the first, second, and third production cycles or the second, third, and fourth production cycles (the following analogy) can be carried out simultaneously in sequence , Therefore, it is indeed possible to achieve the purpose of the invention that is expected to increase the manufacturing speed, shorten the production cycle, and reduce the manufacturing cost.

From the structure and process steps of the paper-plastic product automatic molding machine 1 disclosed above, it can be seen that both the first hot-press upper mold 30 and the second hot-press upper mold 50, the first hot-press lower mold 40 Both the second hot-pressing lower die 60 and the first material receiving mechanism 70 and the second material receiving mechanism 80 are actually of the same structure and used in the same process steps, and only the positions of the two parts are distinguished. It is only the distinction between the two sides of the central space 11; therefore, in terms of actual operation, the paper-plastic product automatic molding machine 1 must have the pulp box 10 and the slurry suction mold 20, if only the first hot-press upper mold 30 and the first hot-press lower die 40 and the first material receiving mechanism 70 exist, or only the second hot-press upper die 50, the second hot-press lower die 60 and the second material receiving mechanism 80 exist, In this way, rapid cold extrusion (dehydration) and rapid hot-press molding can still be performed after slurry suction, so as to achieve the purpose of improving the manufacturing speed, shortening the production cycle, and reducing the manufacturing cost.

In the process steps disclosed in the above-mentioned manufacturing method, the first hot-press upper mold 30 (or the second hot-press upper mold 50 ) and the first hot-press lower mold 40 (or the second hot-press lower mold 60 ) are assembled together. When mold carries out thermocompression molding operation, both of this first thermocompression upper die 30 (or second thermocompression upper die 50) and this first thermocompression lower die 40 (or second thermocompression lower die 60) will be carried out Suction (vacuum) function or blowing (air supply) function. Among them, the suction function is mainly to suck out the water vapor released from the dehumidification of the embryonic product, and the blowing function is to ensure smooth contact with the paper-plastic product. To disengage.

Taking the first hot-pressing upper die 30 as an example, the first hot-pressing upper die 30 is structurally, as shown in Figures 10 to 13, on the die surface of a die table 33, a There are a plurality of air extraction holes 331 (as shown in Figure 12), and the air extraction holes 331 all lead upwards to an air chamber 332 (as shown in Figure 13) inside the mold table 33, and then the air chambers 332 all pass through a suction The air middle section pipe 333 is bent outwards and downwards and connected to a suction collecting pipe 334 (shown in FIGS. 10 and 11 ), and then sucked out by the suction mechanism connected to the rear end of the suction collecting pipe 334; As can be seen from Figure 13, when the inner end of the air extraction middle section pipe 333 is connected to the air chamber 332, the low point position of the inner end of the air extraction middle section pipe 333 is lower than that of the air chamber 332. When pumping air at position 331, the water vapor is pumped up into the air chamber 332, and when the water vapor reaches the air chamber 332, it will be transformed into water and sink in the air chamber 332 due to a slight drop in temperature. The low point position of the inner end of the middle section pipe 333 is lower than the structure of the air chamber 332, which can ensure that the water liquid in the air chamber 332 will definitely enter the air suction middle section pipe 333 to be completely sucked out; The pipe 333 is bent outwards and downwards and then connected to the structure of the air extraction collecting pipe 334, which can ensure that the water liquid is completely discharged and avoids flowing back into the air chamber 332. The structure of the second hot-pressing upper mold 50 is exactly the same as that shown in FIGS. 10 to 13 , so it will not be illustrated and described again.

As for the first hot-pressing lower die 40 and the second hot-pressing lower die 60, because they are turned downwards relative to the first hot-pressing upper die 30 and the second hot-pressing upper die 50, that is, the positions of the suction holes are And the suction hole is located on the top surface of the mold surface, so when the water vapor reaches the air chamber and is converted into water liquid by suction, the water liquid will easily enter the middle section of the suction pipe and be discharged due to gravity, so the air is pumped The low point position of the inner end of the middle pipe can be flush with the air chamber and does not need to be deliberately lowered.

Also take the first hot-pressing upper mold 30 as an example, as shown in Figures 10 to 13, on the mold surface of the mold table 33, a plurality of blowing hole positions 335 are additionally opened on each suction position (as shown in Figure 12), the air blowing holes 335 are all upwards to an air intake pipe 336 (as shown in Figure 13 ) to the inside of the mold table 33, and then the air intake pipe 336 will be connected and collected by an air intake mechanism; The air blowing hole 335 and the air intake pipe 336 are set separately, and not mixed with the air extraction hole 331 and the air chamber 332, mainly because the carbonized fibers deposited in the air chamber 332 are blown to the mold when blowing air. surface and paper plastic products, so the air blowing hole 335 and air intake pipe 336 are separated The setting can completely eliminate the worry that the carbonized fibers deposited in the air chamber 332 will be blown onto the mold surface and paper-plastic products, so as to ensure the cleanliness of the mold surface and paper-plastic products. The second hot-pressing upper die 50, the first hot-pressing lower die 40, and the second hot-pressing lower die 60 are also provided with independently operated air blowing holes and air intake pipes in structure, which are exactly the same as shown in the figure. 10 to 13, so no further illustrations and details are given.

To sum up, the present invention does possess novelty and practical progress, so I apply for a patent for the invention according to law, and I sincerely hope that the patent of this case will be granted as soon as possible after examination.
