Description
Technical Field
The present invention relates to a molding product overturning double-suction automatic molding machine and a manufacturing method for manufacturing a molding product, and more particularly, to a molding product overturning double-suction automatic molding machine which can save assembly space, increase manufacturing speed, increase thickness of the molding product and vibration-proof space, enhance buffering vibration-proof effect, and make surfaces of the molding product overturning double-suction automatic molding machine be smooth, and a manufacturing method for manufacturing the molding product.
Background
The plastic products made of plastic materials have the problems that toxins are easy to release and cause serious pollution to the environment, the toxins are difficult to recycle, or the recycling and decomposing are difficult to treat, the recycling treatment cost is huge, and the like, so that serious injury to global environmental protection is caused for many years. In the current age of high environmental awareness, the search for nontoxic and easily recycled materials has become the mainstream in research and practical application.
At present, pulp fiber materials and/or plant fiber materials are mixed and pulped to form pulp materials, pulp adhesion materials are absorbed by a pulp absorbing mold, and the pulp adhesion materials are manufactured by a hot pressing shaping technology, so that the pulp adhesion materials are different from plastic products, and are generally called as molded products. Molded products have the advantage of easy recycling, reuse, and energy conservation and carbon reduction, and thus are rapidly accepted and favored by industry and general Luo Dazhong, molded products are often seen as: products such as bowls, plates, cup covers, packaging materials, shock absorbing materials, cushion materials and the like are increasingly adopted.
The manufacturing of the molding product is required to go through two operations of 'suction molding' and 'hot press molding', wherein 'suction molding' is to dip a suction lower die into a slurry box filled with slurry, then vacuum suction is carried out on the slurry in the slurry box by a suction device through the suction die, so that a 'embryo layer' is formed on the die surface of the suction die, when the suction die rises and leaves the slurry box, the embryo layer is gradually dehumidified due to continuous suction effect, then the suction die and the embryo layer are lifted together and turned over to press the embryo layer together with a cold die, so that the slurry layer reduces the humidity and is molded into a 'primary embryo', then the suction die is changed to absorb the primary embryo to leave the cold die, the operation of suction molding is completed, and then 'hot press molding' is carried out on the embryo layer after suction molding by means of the hot press die, so that the original embryo layer is dried and molded into a finished product of the molding product.
The present inventors have made a professional work on the production of molded products, and have found that there are drawbacks in the production of molded products through experience of contacting molded products for a long period of time:
1. the manufacturing speed is slow. In the conventional process of producing a molded product, the adsorption operation of the blank layer can be performed only on one side (the side attached to the mold surface), so that the overall wet-down speed of the blank layer is slow and inconsistent, and the production speed is affected.
2. The thickness cannot be increased, resulting in poor shock absorbing effect. When the traditional molded product is manufactured, the slurry suction mold can only cover the blank layer on the mold surface once, and the blank layer cannot be laminated in multiple layers, so that the thickness cannot be increased, and the slurry suction mold is generally only suitable for small products (such as bowls, plates, cup covers and the like) with smooth appearance and without excessive thickness, and if the molded product with relatively thick thickness and better shock absorption effect (such as packaging material with better shock absorption effect) is required to be manufactured, the traditional manufacturing method is difficult to achieve.
3. The surface has non-optimal surface, which causes low value. The conventional molded product has two surfaces, namely, a superior surface on one side and a non-superior surface on the other side, which is suitable for packaging the commodity with extremely high value (such as packaging eggs), but if the molded product is used for packaging the commodity with relatively high value (such as a mobile phone), the appearance is poor due to the fact that the packaging material of the molded product has the non-superior surface, and the value of the whole commodity is reduced.
Because the conventional molded products have the existing defects of low manufacturing speed, difficult thickness increase and non-optimal surface on the surface, the molded products are greatly limited in popularization of use, and cannot be directly used for packaging high-value commodities.

According to the structural composition of the molded product overturning double-suction automatic molding machine, the invention also provides a manufacturing method for manufacturing the molded product by using the molded product overturning double-suction automatic molding machine, and the method comprises the following steps of:
(1) As shown in fig. 2, the suction lower die 40 is first activated to descend and fully immersed in the slurry in the headbox 22.
(2) As shown in FIG. 3, the turning mechanism 10 is started to descend from an initial intermediate position, so that the upper suction mold 30 is immersed in the slurry tank 22, and the upper suction mold 30 is positioned higher than the lower suction mold 40, and then the upper suction mold 30 and the lower suction mold 40 are started to suck slurry simultaneously, so as to form an upper blank layer on the mold surface of the upper suction mold 30 and a lower blank layer on the mold surface of the lower suction mold 40.
(3) As shown in fig. 4, when the suction time is up, the turning mechanism 10 drives the upper suction die 30 and the upper blank layer to move back to the upper position, and simultaneously drives the lower suction die 40 to move up to the upper position, so that the die surface of the lower suction die 40 and the lower blank layer are separated from the pulp surface.
(4) As shown in fig. 5, the turnover mechanism 10 is turned upside down so that the cold press lower die 50 is turned downward and the slurry suction upper die 30 together with the upper blank layer is turned upward.
(5) As shown in fig. 6, the turnover mechanism 10 is lowered, so that the cold press lower die 50 and the pulp suction lower die 40 are clamped for a period of time to squeeze the lower blank layer adsorbed on the pulp suction lower die 40, and at this time, the second pumping device connected to the pulp suction lower die 40 starts the pumping action to dewater the lower blank layer, and the lower blank layer is adsorbed on the pulp suction lower die 40.
(6) As shown in fig. 7, the turnover mechanism 10 is then moved upward to the highest position, so that the upper suction mold 30 and the cold pressing upper mold 60 are clamped for a period of time to squeeze the upper blank layer adsorbed on the upper suction mold 30, and at this time, the first pumping device connected to the upper suction mold 30 starts the pumping action to dehydrate the upper blank layer.
(7) As shown in fig. 8, the turnover mechanism 10 is lowered to the middle position, and the upper blank layer is still adsorbed on the slurry sucking upper die 30.
(8) As shown in fig. 9, the turnover mechanism 10 is turned upside down again to return the cold pressing lower die 50 upwards, and the upper blank layer is sucked by the slurry sucking upper die 30 to be downwards.
(9) As shown in fig. 10, the turning mechanism 10 drives the upper suction mold 30 to adsorb the upper blank layer and descend until the upper suction mold 30 enters the lower suction mold 40 to be clamped for a period of time, and at this time, the upper blank layer and the lower blank layer are combined into a complete thick blank by the upper suction mold 30 and the lower suction mold 40 under the condition of humidity approaching in a coextrusion way, and the thickness of the thick blank is twice that of the upper blank layer or the lower blank layer.
(10) As shown in fig. 11, the first pumping device connected to the upper suction mold 30 continues to suck the thick blank (i.e. the blank layer is sucked from the original upper blank layer), and the second pumping device connected to the lower suction mold 40 stops the pumping, and changes to a blowing (blowing) to release the thick blank from the lower suction mold 40, and then the turning mechanism 10 drives the upper suction mold 30 to suck the thick blank to move upwards beyond the original middle position (i.e. above the middle position).
(11) As shown in fig. 12, the external power mechanism connected to the lower hot press die 70 is activated to push the lower hot press die 70 to move horizontally and laterally to the position right below the upper suction die 30, i.e., right above the lower suction die 40.
(12) As shown in fig. 13, the turnover mechanism 10 drives the pulp suction upper die 30 to adsorb the thick blank and descend until the pulp suction upper die 30 enters the hot pressing lower die 70 to be clamped, and the thick blank is located between the pulp suction upper die 30 and the hot pressing lower die 70.
(13) As shown in fig. 14, the third pumping device connected to the lower hot pressing die 70 starts the pumping action to make the lower hot pressing die 70 absorb the thick blank, and the first pumping device connected to the upper pulp sucking die 30 stops the pumping action, and changes to the blowing (blowing) action to make the thick blank separate from the upper pulp sucking die 30, and then the turning mechanism 10 moves back to the initial middle position to stay, waiting for the next stroke.
(14) As shown in fig. 15, the external power mechanism connected to the lower hot press die 70 pushes the lower hot press die 70 to horizontally and horizontally move back to the right under the upper hot press die 80. At this time, the lower suction die 40, the turnover mechanism 10, the upper suction die 30, etc. can be simultaneously unfolded for the next stroke (i.e., the steps shown in fig. 2 to 11 are unfolded).
(15) As shown in fig. 16, the external power mechanism connected to the upper hot-pressing mold 80 is started to push the upper hot-pressing mold 80 to descend, and finally the upper hot-pressing mold 80 enters the lower hot-pressing mold 70 to be clamped, at this time, the thick blank is placed between the upper hot-pressing mold 80 and the lower hot-pressing mold 70, so that the upper hot-pressing mold 80 and the lower hot-pressing mold 70 together perform hot-pressing shaping operation on the thick blank for a period of time, and the thick blank is dried to be a molded product.
(16) As shown in fig. 17, when the hot press forming operation is completed, the third drawing means connected to the lower hot press mold 70 then starts the suction action to make the lower hot press mold 70 adsorb the molded product, and the fourth drawing means connected to the upper hot press mold 80 starts the blowing action to release the molded product from the upper hot press mold 80, and then the upper hot press mold 80 then moves upward to return. Then, the third pumping means connected to the lower hot press mold 70 stops pumping, and converts into blowing (blowing) to release the molded product from the lower hot press mold 70, and then the molded product is removed from the lower hot press mold 70. The removal of the molded product from the hot press lower die 70 may be performed manually or automatically by a robot.
After the steps are carried out one by one, the expected model product can be manufactured and molded, and besides the thickness of the manufactured and molded product is obviously increased by at least two times, a buffer space can be generated in the finished product of the molded product, so that the pressure-resistant and shock-absorbing effects are improved. Referring to fig. 18, in accordance with the foregoing step 2 (i.e. as shown in fig. 3), the upper suction mold 30 and the lower suction mold 40 simultaneously suck slurry in the slurry tank 22, so that when an upper blank layer and a lower blank layer are respectively adsorbed on the mold surfaces of the upper suction mold 30 and the lower suction mold 40, the mold surfaces of the upper suction mold 30 and the lower suction mold 40 may have the same shape and position, or may have the different shape and position, i.e. the mold surfaces of the upper suction mold 30 and the lower suction mold 40 may be similar to each other in shape symmetry, but have the difference in position at the part.
Therefore, as shown in fig. 19, when the upper suction mold 30 and the lower suction mold 40 are closed according to the above step 9 (i.e. as shown in fig. 10), the upper blank layer and the lower blank layer which are originally adsorbed by the upper suction mold 30 and the lower suction mold 40 respectively are combined into a thick blank with doubled thickness, at this time, it can be seen that a plurality of spaces 31 exist inside the thick blank, because the upper blank layer and the lower blank layer which are originally adsorbed by the upper suction mold 30 and the lower suction mold 40 respectively have different positions due to the shapes of the mold surfaces of the two parts, when the two parts are combined into a thick blank, the parts with the same shapes and positions are bonded, and the parts with different shapes and positions are not bonded, so after the two parts with different shapes and positions are combined into a thick blank, the parts with different positions of the original mold surfaces are generated inside the thick blank, thereby increasing the thickness and producing the effect of buffering space inside the thick blank, thereby achieving the practical efficacy of pressure resistance.
In summary, the present invention has the following excellent effects in use:
1. the present invention is designed to allow both the upper suction die 30 and the lower suction die 40 to suck pulp simultaneously in the headbox 22, thereby increasing manufacturing speed. Such a structural design is not present in any conventional molding machine.
2. In the process of the invention, the upper pulp sucking die 30 and the lower pulp sucking die 40 suck pulp simultaneously to form upper and lower embryo layers, and then the turnover mechanism 10 drives the upper and lower pulp sucking dies to be clamped after the cold die extrusion is completed rapidly, so that the upper and lower embryo layers are combined into thick embryo products with doubled thickness, thereby increasing the thickness and being beneficial to the shock absorbing effect of finished products. Meanwhile, the invention can form a plurality of spaces inside the molded product due to the choice of size design, thereby enhancing the buffering and shock absorbing effects.
3. The invention is designed to make the pulp sucking upper die 30 and the cold pressing lower die 50 respectively arranged on the top and bottom frame setting surfaces of the turnover mechanism 10 occupy only one working position together, so that the working space of the whole device can be reduced.
4. The thick blank formed in the process of the invention is an upper blank layer and a lower blank layer which are respectively adsorbed by the pulp sucking upper die and the lower die, the upper blank layer and the lower blank layer are quickly driven by the turnover mechanism 10 to finish extrusion molding with the cold pressing upper die and the lower die, and then the upper blank layer and the lower blank layer are combined into the thick blank by the die closing of the pulp sucking upper die and the lower die.
5. In the present invention, only the configuration of providing the hot-pressing die 70 and the hot-pressing upper die 80 on one side (right side in the drawing) is disclosed (this is referred to as a single-head machine), and the hot-pressing die 70 and the hot-pressing upper die 80 are capable of heating and pressurizing the thick blank to completely dry the thick blank into a molded product, and the heating and pressurizing time is proportional to the volume of the thick blank, so that if the working time of the hot-pressing lower die 70 and the hot-pressing upper die 80 is required to be longer due to the thickness of the thick blank, the performance of the paste sucking and the extrusion forming is affected (sometimes the operation is required to be stopped and waiting) and the working hours are wasted. Therefore, the present invention can also arrange two groups of the hot pressing lower die 70 and the hot pressing upper die 80 so that they are respectively positioned at two sides of the pulp sucking and extrusion forming operation (namely, the right side and the left side are respectively referred to as a double-head machine), so that after the pulp sucking and extrusion forming operation of the first round is completed, the pulp sucking and extrusion forming operation of the second round can be performed by taking away the hot pressing lower die 70 at one side (for example, the right side), and taking away the thick blank by taking away the hot pressing lower die 70 at the other side (for example, the left side), and the two sides of the hot pressing lower die 70 and the hot pressing upper die 80 alternately take away thick blanks.
6. The thick blank formed in the process of the invention is carried by the hot-pressing lower die 70 to be clamped with the hot-pressing upper die 80 for hot-pressing shaping work, if the hot-pressing time is longer, the hot-pressing lower die 70 and the hot-pressing upper die 80 can be arranged to have two groups on the same side so as to carry out two-stage hot-pressing shaping work on the same thick blank, thereby reducing the whole hot-pressing working time and leading the surface of the molded product to be more excellent.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present invention, and these modifications and substitutions should also be considered as being within the scope of the present invention.
