Description

Multi-stage down-slurry automatic molding machine for molding product and manufacturing method for manufacturing molded product

The present invention relates to a multi-stage down-slurry automatic molding machine for molding products and a manufacturing method for manufacturing the molded product, in particular to a method capable of accelerating the manufacturing speed, increasing the thickness of the molded product and the shock-absorbing space, and gaining a cushioning shock absorber effect, and It is possible to manufacture a multi-stage down-slurry automatic molding machine and a manufacturing method for manufacturing a molded product which have different internal and external hardnesses and/or different internal and external colors and/or different internal and external use characteristics and surfaces.

According to the plastic products made of plastic materials, it is easy to release toxins, which cause serious pollution to the environment, difficult to recycle and reuse, or difficult to recycle and recycle, and the cost of recycling is so large, etc. Global environmental protection has caused serious harm. In today's era of high environmental awareness, the search for non-toxic, easy-to-recycle materials has become the mainstream of research and practical applications.

At present, it has been developed to use a pulp fiber material and/or a plant fiber material as a slurry material, and the slurry is adhered by a suction mold, and then the product is manufactured by hot pressing and setting technology, and is a "plastic product". The distinction is generally referred to as "molded products." Molded products have the advantages of easy recycling, re-manufacture and reuse, and are in line with the trend of environmental protection and energy conservation and carbon reduction. Therefore, they are quickly accepted by the business community and the general public, and molded products are often seen, for example, bowls, plates, Cup lids, packaging materials, shock absorbers, mats, etc. - and other products are gradually adopted.

Molded products must be manufactured by "sucking and shaping" and "hot pressing". Among them, "sucking and shaping" is immersed in a slurry tank filled with slurry by a suction mold. a suction device vacuum-applies the slurry in the slurry tank through the suction mold to form a mold surface of the suction mold a "binder layer", when the suction mold rises out of the pulp box, the billet layer is gradually dehumidified by continuous suction, and then the suction mold rises together with the billet layer and goes to a cold stamping die The blank layer is clamped and extruded, so that the slurry layer is reduced in humidity and simultaneously shaped into an "initial embryo", and then the suction mold adsorbs the original embryo and leaves the cold pressing mold to complete the operation of suction molding. Then, the "hot press setting" operation is performed, in which the blank layer of the suction-shaping shape is subjected to a hot press setting operation by a hot press mold, and the original blank layer is dried and shaped into a finished product of the molded product.

The present inventors specialize in the manufacture of molded products, and through the experience of prolonged contact with molded products, it has been found that the following defects exist in the manufacture of molded products:

1. The adsorption operation of the blank layer in the conventional manufacturing of the molded product can only be performed on one side (the side attached to the mold surface), so that the overall moisture reduction speed of the green layer is slow and inconsistent, thereby affecting the manufacturing speed. Lead to slow manufacturing.

2. When the molded product is traditionally manufactured, the suction mold can only cover the single layer of the blank layer on the die surface, and the layer of the blank cannot be stacked in multiple layers, so the thickness cannot be increased, resulting in poor suspension effect, generally only applicable. For small products (such as bowls, plates, lids, etc.) that have a smoother appearance and need not be too thick in thickness, if you want to make a molded product with a thicker thickness and better shock absorption effect (for example, it has better shock absorption effect). Packaging materials), traditional manufacturing methods are still difficult to achieve.

3. In the traditional manufacture of molded products, the suction mold can only cover the single layer of the blank layer on the mold surface, and the layer of the blank cannot be laminated in multiple layers, so it is impossible to manufacture different hardnesses and/or internal and external colors. / or molded products with different characteristics inside and outside.

4. There is a non-excellent surface on the surface, which leads to a low sense of value. Conventional molded products will obviously have two kinds of surfaces on one side and non-excellent on the other side, which is suitable for packaging non-excellent goods (such as packaged eggs), but if it is used for packaging value When you have a higher quality item (such as a mobile phone), However, due to the presence of "non-excellent noodles" in the packaging materials of molded products, the visual perception is not good, and the value of the overall goods is lowered.

Because conventional molded products have slow manufacturing speed, difficulty in increasing thickness, and the existence of a non-excellent surface on the surface, the molded products are greatly limited in the promotion of use, and cannot be directly used for packaging valuable products.

According to the structural composition of the multi-stage down-slurry automatic molding machine of the above-mentioned molded product, the present invention simultaneously appeals to a manufacturing method for manufacturing a molded product of a multi-stage down-slurry automatic molding machine for a molded product, which is a multi-stage down-feeding using the above-mentioned molded product. The automatic molding machine adopts the following steps: 1. As shown in FIG. 2, the first suction lower mold 31 is started to be immersed in the slurry of the first pulp box 21, and passed through the connected second pumping device. Starting to suck the slurry to form a first layer of the primary layer on the die surface of the first suction die 31; and simultaneously initiating the second suction die 32 to sink into the slurry of the second pulp box 22, And starting the suction by the connected third pumping device to form a second blank layer on the die surface of the second suction lower mold 32; 2.

The second blank layer is also moved upwards away from the slurry surface to return to the original position (the top opening of the second pulp box 22); that is, the suction After the first arrival, the first suction lower mold 31 and the second suction lower mold 32 are all moved back to the position before the lowering; during the process, the second pumping device and the third pumping device continue to suck The first blank layer and the second blank layer are dehumidified; 3. As shown in FIG. 4, the transfer mold 40 is activated to be connected to the power mechanism, and the transfer mold 40 is directly moved downward into the The first suction lower mold 31 is formed by clamping the first blank layer, and then the first pumping device connected to the transfer mold 40 starts suctioning to adsorb the first blank layer, and the first The second pumping device connected to the suction lower mold 31 stops the suction action and is converted into a blowing (air blowing) function to disengage the first blank layer from the first suction lower mold 31; 5, the transfer mold 40 is adsorbed on the first blank layer and moved back to the original position (the upper position in the first main frame space 11); 5. As shown in FIG. 6, the transfer mold 40 is connected to the power mechanism, and the transfer mold 40 is pushed to move the first blank layer horizontally to reach the upper position in the second main frame space 12. 6. As shown in FIG. 7, the transfer mold 40 is activated to be connected to the power mechanism, and the transfer mold 40 is driven to move the first blank layer downwardly into the second suction lower mold 32. At this time, the first blank layer and the second blank layer are co-extruded and combined between the transfer mold 40 and the second suction lower mold 32 to form a thick blank. The thickness of the first blank layer or the second blank layer is twice as long as the first pumping device connected to the transfer mold 40 continues to suck to absorb the thick blank. The third pumping device connected to the second suction lower mold 32 stops the suction action and is converted into a blowing (air blowing) function to disengage the thick blank product from the second suction lower mold 32. The blowing (air supply) action of the three pumping device also dehumidifies the thick blank; 7. as shown in Fig. 8, the transfer mold 40 is attracted to the thick blank and moved back to the The upper position in the second main frame space 12; 8. As shown in FIG. 9, the transfer mold 40 is activated to be connected to the power mechanism, and the transfer die 40 is pushed to adsorb the thick blank to move to the third.

That is, at this time, the transfer mold 40 adsorbs the thick blank and is located directly above the hot pressing mold 51. 9. As shown in FIG. 10, the transfer mold 40 is attracted to the thick blank to move down. The hot pressing lower mold 51 is formed by extrusion molding, and then the fourth pumping device connected to the hot pressing lower mold 51 starts suctioning to adsorb the thick blank, and the first pumping of the transfer mold 40 is connected. The device stops the pumping action and converts into a blowing (air blowing) action to disengage the thick blank product from the transfer mold 40; 10. As shown in FIG. 11, the transfer die 40 is moved back to the upper position in the third main frame space 13, and the hot pressing die 51 continues to adsorb the thick blank; 11.

The hot pressing upper mold 52 is connected to the power mechanism, and the hot pressing upper mold 52 is pushed down, and finally the hot pressing upper mold 52 enters the hot pressing lower mold 51 to clamp the mold, and the thick blank product is Between the hot pressing upper mold 52 and the hot pressing lower mold 51, the hot pressing upper mold 52 and the hot pressing lower mold 51 jointly perform a hot pressing setting operation on the thick blank product for a period of time, so that the thick embryo The product is completely dried to become a molded product; 13. As shown in FIG. 14, when the hot pressing setting operation time is up, the fifth pumping device connected to the hot pressing upper mold 52 starts suctioning. Used to adsorb the molded product, and the fourth pumping device to which the hot press die 51 is connected initiates a blowing (air blowing) action to disengage the hot press die 51 from the molded product, and then the The hot stamping upper mold 52 adsorbs the molded product and moves back to the position; finally, the molded product is received by the mechanical arm near the bottom surface of the hot pressing upper mold 52, and the fifth pumping device to which the hot pressing upper mold 52 is connected The suction is stopped and converted into a blowing (air blowing) action to disengage the molded product from the hot press upper mold 52, and then the molded product can be removed from the hot press upper mold 52.

After the above steps are carried out one by one, the intended molded product can be molded, and the molded product produced can be produced in the finished product of the molded product in addition to the thickness of the molded product at least twice. Buffer space to enhance the pressure and shock absorption effect. Referring to FIG. 15 , the first suction lower mold 31 and the second suction lower mold 32 are respectively in the first step according to the foregoing step 1 (ie, as shown in FIG. 2 ). Simultaneously sucking the slurry in the first and second slurry tanks 21 and 22, respectively, to adsorb and form the first material layer on the first suction mold 31 and the second suction mold 32. In the second blank layer, the suction surface provided by the first suction lower mold 31 and the suction surface provided by the second suction lower mold 32 may have a partial shape and a similar position. There may also be a partial shape and a position difference, that is, the suction surface of the first suction lower mold 31 and the second suction lower mold 32 are similar in shape, but there are Some parts will have different positions.

Therefore, as shown in FIG. 16, when the transfer mold 40 is adsorbed to move the second blank layer into the second suction mold 32, the second adsorption is performed. When the blank is clamped in the billet layer, the first billet layer and the second billet layer of the original single layer are co-extruded together between the transfer mold 40 and the second suction mold 32 to become a thickness double. Thick embryos, it can be seen at this time that there are some spaces S inside the thick blank, which is due to the fact that both the first and second blank layers of the original single layer have a part of the initial shape. The position has a difference in position. Therefore, after the extrusion is combined into a thick blank, the position of the original blank layer is different, that is, the space S is generated inside the thick blank, and the thickness can be increased and the buffer space can be generated. The effect is to enhance the practical effect of pressure and shock absorption.

In summary, the present invention has the following excellent effects in use;

1. The present invention discloses that both the first suction lower mold 31 and the second suction lower mold 32 simultaneously suck the slurry in the first pulp tank 21 and the second pulp tank 22, respectively, which can speed up the manufacturing speed; The structural design is currently not available in any conventional molding product manufacturing machine; more importantly, the slurry placed in the first and second pulp boxes 21 and 22 may be of different concentrations and/or different colors and/or different materials. Characterized by molding a molded product that has different internal and external hardness and/or different internal and external colors and/or different internal and external use characteristics (for example, different internal and external toughness), or may be formed by double-layered blank lamination molding. therefore The effect of reinforcing the thickness and/or the color and/or the characteristic of only part of the part is achieved. In detail, the automatic molding machine and the manufacturing method of the invention can be used to manufacture different products with different styles.

2. In the process, the first slurry lower mold 31 and the second liquid suction lower mold 32 are simultaneously sucked into the first blank layer and the second blank layer, and then driven by the transfer mold 40 respectively. Extrusion molding and re-molding, the first blank layer and the second blank layer are combined to form a thick double-thickness blank, so that the thickness can be increased to benefit the shock-absorbing effect of the finished product; at the same time, the invention can be designed according to the size The choice of the above makes a certain space inside the molded product, thereby enhancing the buffer suspension effect.

3. The present invention provides a two-stage suction lower mold (ie, the first suction lower mold 31 and the second suction lower mold 32) is matched with a two-stage pulp tank (ie, the first pulp tank 21 and the second pulp) The box 22) is used for the description of the embodiment. However, in practice, the suction lower mold and the pulp box are not limited to the second stage, and may be two or more stages (at least two stages) of the suction lower mold, and then the second stage or more. (at least two stages) of the pulp tank is used correspondingly, and then the transfer mold 40 is sequentially pressed and clamped into two or more (at least two) suction molds to increase the thickness (at least two times). Thick blanks; therefore, the "multi-stage down-slurry" in the patent name "molding product multi-stage under-slurry automatic forming machine---" means at least two or more movements under the finger, that is, at least the first A suction lower mold 31 and the second suction lower mold 32 are above.

4. The thick blank formed in the process of the present invention is obtained by simultaneously sucking the first suction lower mold 31 and the second suction lower mold 32 into a first blank layer and a second blank layer. Then, through the transfer die 40, respectively, the extrusion molding and the clamping are carried out, so that the first blank layer and the second blank layer are combined to form a thick double-thickness blank, because the outer surface of the thick blank is the first suction.
