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.

The above structure forms the automatic molding machine for overturning and double suction pulp of the molded product, wherein the external power mechanism and the first, second, third, fourth and fifth pumping devices are not main structures of the invention, and the functions of the external power mechanism and the first, second, third, fourth and fifth pumping devices are obviously established, so the external power mechanism and the first, second, third, fourth and fifth pumping devices are not shown in the drawings, and the drawing is not complicated and difficult to distinguish.
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 turning mechanism 10 is started to descend from the initial middle position, so that the first suction mold 30 is immersed into the slurry in the slurry tank 22, and then the first suction mold 30 is started to suck the slurry, so as to form an upper blank layer on the mold surface of the first suction mold 30.
(2) As shown in fig. 3, the turning mechanism 10 drives the first suction die 30 to move back to the middle position together with the upper blank layer as soon as the suction time is reached.
(3) As shown in fig. 4, the turnover mechanism 10 is turned upside down so that the second suction die 40 is turned downward and the first suction die 30 is turned upward together with the upper blank layer.
(4) As shown in fig. 5, the turnover mechanism 10 is lowered to immerse the second suction die 40 in the slurry tank 22, and then the second suction die 40 is started to suck the slurry to form a blank layer on the die surface of the second suction die 40.
(5) As shown in fig. 6, the turnover mechanism 10 is moved upward to the highest position, so that the first suction mold 30 and the cold pressing mold 60 are closed for a period of time to squeeze the upper blank layer adsorbed on the first suction mold 30, and at this time, the first pumping device connected to the first suction mold 30 and the third pumping device connected to the cold pressing mold 60 both start pumping action to dehydrate the upper blank layer.
(6) As shown in fig. 7, when the pressing time is reached, the suction of the first suction means connected to the first suction die 30 is stopped, and the suction is converted into the blowing (blowing) so as to release the upper stock layer from the first suction die 30, and the third suction means connected to the cold die 60 continues the suction so as to allow the upper stock layer to be sucked into the cold die 60, and then the tilting mechanism 10 is lowered to the intermediate position.
(7) As shown in fig. 8, the turnover mechanism 10 is turned upside down again, so that the lower blank layer is sucked by the second suction die 40 and turned upwards, and the first suction die 30 is turned downwards.
(8) As shown in fig. 9, the turnover mechanism 10 drives the second suction mold 40 to adsorb the lower blank layer to rise until the second suction mold 40 enters the cold mold 60 to be clamped for a period of time, and at this time, the lower blank layer adsorbed by the second suction mold 40 and the upper blank layer adsorbed by the cold mold 60 are combined by the second suction mold 40 and the cold mold 60 together to form a complete thick blank, the thickness of which is twice that of the upper blank layer or the lower blank layer. The second pumping means connected to the second suction die 40 and the third pumping means connected to the cold die 60 are both activated during the pressing process to continuously dehydrate the thick blanks.
(9) As shown in fig. 10, when the pressing time is reached, the suction of the third suction means connected to the cold pressing die 60 is stopped, and the blowing (blowing) is switched to release the thick blank from the cold pressing die 60, and the second suction means connected to the second suction die 40 continues the suction so that the thick blank is sucked to the second suction die 40, and then the tilting mechanism 10 is lowered to the intermediate position.
(10) As shown in fig. 11, the turnover mechanism 10 is turned upside down again, so that the second suction mold 40 sucks the thick blank to be turned downwards, the first suction mold 30 is turned upwards, and then the turnover mechanism 10 drives the second suction mold 40 to suck the thick blank to move upwards beyond the initial middle position (i.e. above the middle position).
(11) As shown in fig. 12, an external power mechanism connected to the lower thermo-compression mold 70 is activated to push the lower thermo-compression mold 70 to move horizontally and laterally to a position immediately below the second suction mold 40.
(12) As shown in fig. 13, the turnover mechanism 10 drives the second pulp suction mold 40 to adsorb the thick blank and descend until the second pulp suction mold 40 enters the hot pressing lower mold 70 to mold, and the thick blank is located between the second pulp suction mold 40 and the hot pressing lower mold 70.
(13) As shown in fig. 14, the fourth pumping device connected to the lower hot pressing die 70 then starts the pumping action to make the lower hot pressing die 70 absorb the thick blank, and the second pumping device connected to the second suction die 40 stops the pumping action and changes to the blowing (blowing) action to disengage the thick blank from the second suction die 40, and then the tilting mechanism 10 moves back to the initial middle position to stay 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 turnover mechanism 10 turns up and down again to make the first suction die 30 return to the downward direction and the second suction die 40 return to the upward direction, so that the first suction die 30, the turnover mechanism 10, the second suction die 40 and the cold pressing die 60 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 completely dried to form a molded product.
(16) As shown in fig. 17, when the hot press forming operation is completed, the fourth drawing means connected to the lower hot press mold 70 then starts the suction operation to make the lower hot press mold 70 absorb the molded product, and the fifth drawing means connected to the upper hot press mold 80 starts the blowing (blowing) operation 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 fourth 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, according to the foregoing steps 2 (i.e. fig. 3) and 4 (i.e. fig. 5), the first suction mold 30 and the second suction mold 40 respectively suck the slurry in the slurry tank 22, so that when an upper blank layer and a lower blank layer are respectively sucked onto the mold surfaces of the first suction mold 30 and the second suction mold 40, the mold surfaces of the first suction mold 30 and the second suction mold 40 may have the same shape and position, or may have the same shape and position, i.e. the mold surfaces of the first suction mold 30 and the second suction mold 40 are similar to each other in shape, but have the different positions.
Therefore, as shown in fig. 19, when the second suction mold 40 and the cold mold 60 are closed according to the above step 8 (i.e. as shown in fig. 9), the upper blank layer and the lower blank layer which are originally absorbed by the cold mold 60 and the second 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 absorbed by the first suction mold 30 and the second suction mold 40 respectively have different positions due to the shapes of the mold surfaces of the two molds, when the two molds are combined into the thick blank, the same positions of the two molds and the positions are bonded, the positions of the two molds and the positions of the two different positions are not bonded, so that after the mold is closed into the thick blank, the positions of the two molds and the positions of the two molds are different from each other generate the spaces 31 inside the thick blank, thereby achieving the effects of increasing the thickness and producing the buffer space inside the thick blank, and improving the practicability.
In summary, the present invention has the following excellent effects in use:
1. in the invention, the first pulp sucking die and the second pulp sucking die are respectively used for sucking pulp in the pulp box in the same process, so that the manufacturing speed can be increased; such a structural design is not present in any conventional molding machine.
2. In the invention, the first pulp sucking die and the second pulp sucking die suck pulp respectively to finish an upper blank layer and a lower blank layer in the process, and then the turnover mechanism drives the upper blank layer and the lower blank layer to be combined into a thick blank with doubled thickness after the cold die extrusion is finished rapidly, so that the thickness can be increased, and the shock absorbing effect of a finished product is improved; 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 first pulp sucking mould and the second pulp sucking mould respectively arranged on the top and bottom frame setting surfaces of the turnover mechanism and occupy only one working position together, thus reducing the working space of the whole device.
4. In the process, the first pulp sucking die and the second pulp sucking die suck pulp respectively to form an upper blank layer and a lower blank layer, and the upper blank layer and the lower blank layer are combined into a thick blank with doubled thickness after being driven by the turnover mechanism to finish cold die extrusion, and the outer surfaces of the thick blank are excellent surfaces formed by tightly attaching the pulp sucking surfaces of the first pulp sucking die and the second pulp sucking die, so that the outer surfaces of molded products after hot press shaping are excellent surfaces, and the whole value sense of packaged goods is improved.
5.

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.
