Abstract

The present invention provides an automatic forming machine and manufacturing method of flip-type pulp-suction paper-molding product. A pulp suction mold enters a pulp box to suck pulp for forming a slurry layer, which is molded with a cold compression mold and squeezed into a preliminary blank product. Then, the preliminary blank product is subject to a hot pressing for being molded by the upper and lower molds and thermally shaped as a paper-molding product, which is taken over by a transfer mold. Finally, a downward movement mechanism of a reclaiming mechanism of a reclaiming robot arm drives a suction mechanism to move down and suck the paper-molding product for moving the sucked paper-molding product up to leave the transfer mold, then the paper-molding product is moved by a sliding mechanism of the reclaiming robot arm to the top of a conveying mechanism, and subsequently the suction of the paper-molding product is stopped, so that the paper-molding product falls on the conveying mechanism for being immediately driven away or transferred to other subsequent processes.

Description

Turnover type suction paddle paper-plastic product automatic molding machine and manufacturing method

The invention relates to an automatic forming machine and a manufacturing method for a flip-type suction paddle paper-plastic product, in particular to a flip-type suction paddle paper-plastic product automatic molding machine and a manufacturing method that can shorten the production cycle and reduce the manufacturing cost.

According to this, at present, there have been developed products that are made by mixing pulp fiber materials and/or plant fiber materials as pulp materials, attaching the pulp through a suction mold, and then undergoing hot-pressing shaping technology. "Products" are generally referred to as "paper-plastic products". Paper-plastic products have the advantage of being easily recycled, remanufactured and reused, and are in line with the trend of environmentally friendly reuse and energy saving and carbon reduction. Therefore, they are quickly accepted and adopted by the industrial and commercial industry and the general public. Cup lids, packaging materials, shock-absorbing materials, cushion materials, etc. --- and other products are gradually being adopted.

It is known that the manufacturing process of paper-plastic products with small draft angles generally must go through three continuous operations, namely "suction forming", "hot pressing shaping" and "finished product transfer". A conventional structure and composition of a flip-type pulp-absorbing paper-plastic product automatic molding machine suitable for manufacturing small draft angle paper-plastic products, as shown in Figure 1, has: a first supporting space 10; a slurry suction mold 11, Set within the range of the first support space 10, it can move up and down and flip up and down when driven. When the zero state (or initial state) is set, the suction mold 11 faces downwards, and the suction The slurry mold 11 is connected to a first pumping device, which can provide suction or blowing to the slurry suction mold 11; a cold pressing mold 12 is fixedly installed on the top of the first supporting space 10, the cold pressing mold 12 The mold surface is always facing downwards, the cold pressing mold 12 is connected to a second pumping device, which can provide suction or blowing to the cold pressing mold 12; a slurry tank 13 is arranged at the bottom of the first supporting space 10, For injecting the slurry; a second supporting space 20, arranged on one side of the first supporting space 10; a hot pressing upper mold 21, arranged on the top of the second supporting space 20 and adjacent to the first supporting space 10. The hot pressing upper mold 21 is connected to a third pumping device, which can provide suction or blowing to the hot pressing upper mold 21; a hot pressing lower mold 22 is arranged at the inner bottom of the second supporting space 20, It can be horizontally moved left and right when supported. The hot pressing die 22 is connected to a fourth pumping device, which can provide suction or blowing to the hot pressing die 22; a transfer die 23 is arranged in the second supporting space 20, and adjacent to the hot pressing upper mold 21, the transfer mold 23 is connected to a fifth pumping device, which can provide suction or blowing to the transfer mold 23; and a receiving platform 24, set on the hot The pressing mold 22 is adjacent to the side, and is connected to the hot pressing mold 22 at a fixed distance, so it can move with the hot pressing mold 22. In the zero state (or initial state), the material receiving platform 24 is located at the first 2. The outside of support space 20.

The process steps of the conventional automatic forming machine for pulp-absorbing paper-plastic products are shown in Figures 2-9. 1. As shown in Figure 2, first start the suction of the first pumping device and lower the slurry suction mold 11, so that the mold surface enters the slurry in the slurry tank 13 to suction slurry on the mold surface. A slurry layer, and at the same time, the lower hot pressing mold 22 is moved to stay relatively below the upper hot pressing mold 21, during the process the receiving platform 24 is driven into the second supporting space 20 and stays relatively below the transfer mold 23 . 2. As shown in Figure 3, make the mold surface of the slurry suction mold 11 absorb the slurry layer and rise away from the slurry tank 13, and turn it over so that the mold surface absorbs the slurry layer upward, and then rise to make the mold surface adsorb Hold the slurry layer and the die surface of the cold press mold 12 together to extrude the slurry layer to form a preliminary product. In the process, the first and second pumping devices both perform suction to make the The primordial product continues to reduce moisture. 3. As shown in Figure 4, when the molding time is up, the second pumping device is switched to blowing to separate the preliminary product from the mold surface of the cold press mold 12, and then the slurry suction mold 11 is absorbed The primary embryo descends and leaves the cold pressing mold 12, and turns over so that the mold surface adsorbs the primary embryo downward, and at the same time, the hot pressing mold 22 is moved to stay relatively below the slurry suction mold 11. In the process, the receiving material The platform 24 is driven to move with it. 4. As shown in Fig. 5, the slurry suction mold 11 adsorbs the preliminary product and is lowered to close the mold surface of the hot pressing lower mold 22. At this time, the fourth pumping device starts the suction action to make the hot pressing The mold surface of the lower mold 22 adsorbs the primary embryo, and the first pumping device is converted to a blowing function to separate the primary embryo from the mold surface of the slurry suction mold 11. 5. As shown in Figure 6, make the slurry suction mold 11 move up and return to the original position, and then the die surface of the hot pressing lower mold 22 absorbs the preliminary product and moves in the reverse direction, returning to the hot pressing The upper mold 21 stays relatively downward, and then the hot-pressing upper mold 21 is lowered to be closed with the hot-pressing lower mold 22, and the preliminary product is hot-pressed and shaped into a paper-plastic product. In the process, the third and fourth The pumping devices all start the suction action, so that the preliminary product can be dried into a paper-plastic product as soon as possible. 6. As shown in Figure 7, as soon as the hot-press setting time is up, the third pumping device is converted to a blowing function to separate the paper-plastic product from the hot-press upper mold 21 and make the hot-press upper mold 21 rise back Position, the hot pressing lower mold 22 still adsorbs the paper-plastic product and moves to stay relatively below the transfer mold 23. During the process, the receiving platform 24 is driven to move with it, and then the transfer mold 23 is lowered and the hot pressing The lower mold 22 is closed, and at the same time, the fourth pumping device is converted into a blowing function to separate the paper-plastic product from the hot pressing lower mold 22, and the fifth pumping device starts a suction function to switch to the transfer The mold 23 absorbs the paper-plastic product. 7. As shown in Figure 8, the transfer mold 23 absorbs the paper-plastic product and rises back to the position, and at the same time makes the lower hot pressing mold 22 move to stay relatively below the upper hot pressing mold 21, so the receiving platform 24 is Drive to move to the relatively lower position of the transfer mold 23, and then the fifth pumping device is converted to a blowing function to blow the paper-plastic product to the receiving platform 24 to stay, so that the finished product transfer is taken over by the receiving platform 24 . 8. As shown in Fig. 9, the lower hot pressing mold 22 is moved to stay relatively below the transfer mold 23, so that the receiving platform 24 accepts the movement of the paper-plastic product to the outside of the second supporting space 20, so that it can be moved by manpower Take off for finishing work.

It can be seen from the above process steps that the production cycle of the conventional automatic reversing pulp suction paper-plastic product forming machine is the sum of the "suction forming time", "hot pressing setting time" and "finished product transfer time". The hot-pressing lower mold 22 must be in three areas separated by the "slurry suction forming zone" (in the first supporting space 10) and the "hot-pressing shaping zone" and the "finished product transfer zone" (in the second supporting space 20). Quickly switch and move within each area to complete the manufacture of paper-plastic products. Because the above process steps cannot be reduced at all, the production cycle cannot be shortened accordingly, resulting in the inability to reduce manufacturing costs. In the industrial age where time is money, efforts to reduce costs are the kingly way, so the inventor has the idea of improvement.

In view of the above shortcomings, the present inventors intensively conceived, developed and improved, and hoped to provide a completely new structure and composition of the automatic forming machine and manufacturing method for the flip-type pulp-absorbing paper-plastic products to solve the above shortcomings.

Among them, the first, second, third, fourth, and fifth pumping devices mentioned are not the main structure of the present invention, and their functions Obviously it can be established, so it is not shown in the figure, so as not to be too complicated and difficult to distinguish.

According to the structure and composition of the above-mentioned flip-type suction paddle paper-plastic product automatic molding machine, the present invention also seeks a method for manufacturing a flip-type suction paddle paper-plastic product automatic molding machine. For example, the above-mentioned flip-type suction paddle paper-plastic product automatic molding machine is used. , And then take the following steps: 1. As shown in Figure 11, start the suction of the first pumping device and lower the slurry suction mold 31 so that the mold surface enters the slurry in the slurry tank 33 to suction slurry. A slurry layer is formed by adsorption on the mold surface. 2. As shown in Fig. 12, make the mold surface of the slurry suction mold 31 absorb the slurry layer and rise away from the slurry tank 33, and turn it over so that the mold surface absorbs the slurry layer upward. 3. As shown in Fig. 13, the mold surface of the slurry suction mold 31 absorbs the slurry layer and rises so that it is closed with the mold surface of the cold press mold 32 to extrude the slurry layer, forming a preliminary product together. , During the process, the first and second pumping devices both perform suction to make the primary embryo continue to dehumidify. 4. As shown in Figure 14, when the molding time is up, the second pumping device is switched to blowing to separate the preliminary product from the mold surface of the cold press mold 32, and then the slurry suction mold 31 is absorbed The preliminary product descends and leaves the cold pressing mold 32, and is turned over so that the mold surface adsorbs the preliminary product downward. 5. As shown in Fig. 15, the hot pressing lower mold 42 is moved to stay relatively below the slurry suction mold 31. During the process, the transfer mold 44 is driven to move with it, and then the slurry suction mold 31 is made to adsorb the preliminary product Descend to mate with the die surface of the hot press lower mold 42. At this time, the fourth pumping device starts the suction action, so that the die surface of the hot press lower mold 42 absorbs the preliminary product, and the first pumping device switches For the blowing effect, the primary embryo product is separated from the mold surface of the slurry suction mold 31. 6. As shown in Figure 16, make the slurry suction mold 31 move upward and return to the original position, and then the mold surface of the hot pressing lower mold 42 will absorb the preliminary product and move in the reverse direction, returning to the hot pressing The upper mold 41 stays relatively below, and in the process, the transfer mold 44 is driven to move back in the reverse direction. 7. As shown in Figure 17, the upper hot-pressing mold 41 is lowered and the lower hot-pressing mold 42 is closed, and the preliminary product is hot-pressed and shaped to become a paper-plastic product. In the process, the third, The four pumping devices all start the suction action to make the preliminary product dry as quickly as possible into a paper-plastic product; at the same time as this process, the slurry suction mold 31 can be lowered for the second time into the slurry tank 33 to suction slurry. A slurry layer is formed by adsorption on the mold surface. The second-degree suction suction of the slurry suction mold 31 belongs to another (second) production cycle, that is, at this time, the first production cycle is still in progress, and The second production cycle has already started. 8. As shown in Figure 18, when the first production cycle is still in the hot pressing and shaping operation, the slurry suction mold 31 belonging to the second production cycle has attached the slurry layer and rises away from the slurry tank 33, and turns and rises The cold pressing die 32 is closed to extrude the slurry layer to be molded into a preliminary product belonging to the second production cycle. 9. As shown in Figure 19, when the hot-press setting time belonging to the first production cycle is up, the fourth pumping device is converted to blowing, so that the paper-plastic product is separated from the hot-press lower mold 42, and the third pumping The device still performs suction to make the hot-press upper mold 41 absorb the paper-plastic product, and make the hot-press upper mold 41 absorb the paper-plastic product and rise back. At the same time, it belongs to the second production When the molding time of the cycle is up, the slurry suction mold 31 absorbs the primary embryo and descends away from the cold pressing mold 32, and turns over to make the primary embryo face downward. 10. As shown in Figure 20, the hot pressing lower mold 42 moves to a relatively below the slurry suction mold 31, and then the slurry suction mold 31 absorbs the preliminary product (belonging to the second production cycle) and descends and the hot pressure lower mold 42 closes the mold. At the same time as the process, the fourth pumping device starts the suction action, so that the die surface of the hot pressing mold 42 absorbs the preliminary product (belonging to the second production cycle), and the first pumping device is converted to The blowing action separates the preliminary product from the slurry suction mold 31. At the same time, the transfer mold 44 is driven by the slurry suction mold 31 to move to the lower side of the hot pressing upper mold 41 at the same time. The upper pressing mold 41 absorbs the paper-plastic product (belonging to the first production cycle) and closes with the transfer mold 44, so that the paper-plastic product (belonging to the first production cycle) correspondingly enters the receiving mold on the transfer mold 44 At the same time, the fifth pumping device starts the suction to absorb the paper-plastic product (belonging to the first production cycle). 11. As shown in Figure 21, the third pumping device is converted into a blowing function, so that the paper-plastic product (belonging to the first production cycle) is separated from the hot pressing upper mold 41, and then the hot pressing upper mold 41 rises back to position During the process, at the same time, the slurry suction mold 311 rises back to the original position, and the hot press lower mold 42 adsorbs the preliminary product (belonging to the second production cycle). 12. As shown in Figure 22, the lower hot press mold 42 adsorbs the primary product (belonging to the second production cycle) and moves in the reverse direction, and returns to the upper hot press mold 41 to stay relatively below, while the transfer mold 44 also drives The paper-plastic product (belonging to the first production cycle) moves in the reverse direction and returns to the reclaiming mechanism 432 of the reclaiming robotic arm 43 to stay relatively below. 13. As shown in Fig. 23, the lowering mechanism of the reclaiming mechanism 432 of the reclaiming robot arm 43 is made to drive the suction mechanism to descend and absorb the paper-plastic product (belonging to the first production cycle), and at the same time to make the hot pressing upper mold 41 Draw down and close the hot-press lower mold 42, and heat-press and shape the primary product (belonging to the second production cycle) to make it a paper-plastic product belonging to the second production cycle. During the process, the third and fourth pumping The devices all start the suction function, so that the preliminary product (belonging to the second production cycle) is dried as quickly as possible into a paper-plastic product (belonging to the second production cycle); at the same time as this process, it can make the suction mold 31 third The degree of lowering enters into the slurry tank 33 to absorb slurry to form a slurry layer on the mold surface. The third degree of downward slurry suction of the slurry suction mold 31 belongs to another (third) production cycle, that is, here At that time, the first production cycle and the second production cycle are still in progress, and the third production cycle has already started. 14. As shown in Fig. 24, the downward moving mechanism of the reclaiming mechanism 432 of the reclaiming robot arm 43 drives the suction mechanism to absorb the paper-plastic product belonging to the first production cycle and move up to the position, and leave the transfer mold 44 at the same time. As soon as the hot pressing setting time belonging to the second production cycle is up, the fourth pumping device is converted to blowing, so that the paper-plastic product belonging to the second production cycle is separated from the hot pressing lower mold 42, and the third pumping device Suction is still performed to make the hot press upper mold 41 adsorb the paper-plastic product (belonging to the second production cycle), and make the hot press upper mold 41 adsorb the paper-plastic product (belonging to the second production cycle) rise When returning to the position, at the same time as this process, the slurry suction mold 31 has absorbed the slurry layer belonging to the third production cycle and rises away from the slurry tank 33, and turns and rises to close with the cold press mold 32 to extrude the slurry layer. After being shaped into a preliminary product belonging to the third production cycle, the slurry suction mold 31 absorbs the preliminary product (belonging to the third production cycle) and descends from the cold press mold 32. 15. As shown in FIG. 25, the sliding mechanism 431 of the reclaiming robot arm 43 drives the reclaiming mechanism 432 to adsorb the paper-plastic products belonging to the first production cycle and move outward to the top of the conveying mechanism 45, and then the reclaiming The adsorption mechanism of the mechanism 432 stops the adsorption of the paper-plastic product (belonging to the first production cycle), so that the paper-plastic product (belonging to the first production cycle) is separated from the reclaiming robot 43 and falls on the conveying mechanism 45 (top Surface is the conveying plane), then it is driven away by the conveying mechanism 45, or the paper-plastic product can be separated from the reclaiming robot 43 and fall into the profiling jig on the top surface of the conveying mechanism 45 to remove The paper-plastic product is transferred to the subsequent process (for example: trimming, inspection, packaging), and the first production cycle is completed. At the same time, the hot pressing lower mold 42 is moved to the suction mold 31 to stay relatively below. The transfer mold 44 moves to the lower hot-pressing upper mold 41 to stay relatively, therefore, the hot-pressing upper mold 41 is lowered to transfer the paper-plastic product (belonging to the second production cycle) to the transfer mold 44 to accept, and the slurry suction mold 31 absorbs the preliminary product (belonging to the third production cycle), turns and closes it with the hot-press lower mold 42, so as to transfer the preliminary product (belongs to the third production cycle) to the hot-press lower mold 42 to accept. The first, second, and third production cycles can be carried out simultaneously in order to greatly shorten the production cycle.
