Description

Technical Field

[0001] The present invention relates to the field of hot pressing, and particularly to a paper-plastic hot press. Background Art

[0002] As is known, a hot press heats a hot pressing plate to a set temperature through a heating system (such as electric heating, oil heating or electromagnetic heating), and the heat is transferred to the material to be processed, so that the material is softened, melted or undergoes a chemical reaction, thereby improving the plasticity or bonding ability of the material. And pressure is applied through a hydraulic system, a pneumatic system or a mechanical system, so that the materials are in close contact at high temperature. The pressure can eliminate the bubbles, voids or non-uniformities between the materials and ensure the tight bonding of the materials.

[0003] For example, in a Chinese patent document with the authorization announcement number CN109736139B, the announcement date of June 8, 2021, and the name of "A Forming Device and Method for Pulp Molding", it includes: a slurry suction mold forms a wet blank after sucking slurry from a slurry pool; an extrusion mold is arranged corresponding to the upper part of the slurry suction mold. After the slurry suction mold drives the wet blank to reverse upward, the wet blank is initially extruded with the extrusion mold; a hot pressing upper mold can move up and down in the vertical direction; a hot pressing lower mold can move left and right in the horizontal direction. When it moves to be vertically corresponding to the hot pressing lower mold, hot pressing treatment is performed on the wet blank; an air suction structure is arranged in the hot pressing upper mold, and a blowing structure is arranged in the hot pressing lower mold; the present invention also discloses a forming method for pulp molding, including slurry suction, extrusion, hot pressing, and transfer. After heating is completed, when the hot pressing upper mold and the hot pressing lower mold are separated, the formed molded product is adsorbed and transferred by the hot pressing upper mold. The above equipment and method reduce the forming movement time of the equipment and improve the cycle period of the equipment for preparing molded products.

[0004] The disadvantages of the above-mentioned prior art are that when loading the hot press, when the hot press has multiple stations, the above-mentioned cyclic feeding method can be adopted to improve the hot pressing efficiency of paper-plastic. However, when there is only one hot pressing station, after the paper-plastic is hot pressed, it is necessary to first remove the finished product, and then place the semi-finished product to be hot pressed on the hot press, and the operation is relatively cumbersome. Summary of the Invention

[0005] The purpose of the present invention is to provide a paper-plastic hot press to solve the above-mentioned deficiencies in the prior art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0008] During the process of the first adsorption component removing the paper-plastic finished product from the upper mold, the second adsorption component feeds the paper-plastic semi-finished product onto the lower mold.

[0033] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further introduced in detail below with reference to the accompanying drawings.

[0034] In the description of the present invention, it should be understood that taking Figure 4 the position of the upper die 3 relative to the lower die 2 as up, and vice versa as down, the terms "center", "longitudinal", "transverse", "length", "width", "up", "down", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0035] Refer to Figures 1-11 , a paper-plastic hot press provided by an embodiment of the present invention includes a machine body 1 and a lower die 2 provided on the machine body 1. An upper die 3 adapted to the lower die 2 is also slidably provided on the machine body 1. The paper-plastic hot press further includes a loading plate 4. A first adsorption assembly 5 is provided above the loading plate 4, and a second adsorption assembly 6 is provided below the loading plate 4;

[0036] During the process of the first adsorption assembly 5 removing the paper-plastic finished product (hereinafter referred to as the finished product for the convenience of description) from the upper die 3, the second adsorption assembly 6 feeds the paper-plastic semi-finished product (hereinafter referred to as the semi-finished product for the convenience of description) onto the lower die 2.

[0037] Specifically, the whole body 1 is of a frame structure. The upper die 3 is a convex die, which is slidably arranged on the body 1. The lower die 2 is a concave die, which is fixedly arranged on the body 1. And a heating system (such as electric heating or electromagnetic heating, not shown) is arranged inside the upper die 3. The hot press heats the hot pressing plate to a set temperature through the heating system, transfers the heat to the material to be processed, and under physical pressure, makes the materials closely contact under high temperature and high pressure conditions to ensure the materials are tightly combined. During hot pressing, the semi-finished product is placed on the surface of the lower die 2, and then the upper die 3 is controlled to move downward to realize the hot pressing process. After hot pressing is completed, the upper die 3 is lifted, and the finished product will adhere to the surface of the upper die 3 (which can be realized through a vacuum suction structure, see the patent document with the authorization announcement number CN109736139B for details), and then the finished product is taken off to complete the hot pressing process. Then the semi-finished product is sent to the lower die 2 for the next hot pressing. This is the prior art and will not be elaborated. One of the core innovation points of the embodiment of the present invention is that a first adsorption component 5 is arranged on the loading plate 4, and a second adsorption component 6 is arranged on its lower surface. The first adsorption component 5 and the second adsorption component 6 are preferably vacuum suction cups, and their quantity and positions are arranged corresponding to the quantity and positions of the products hot pressed by the hot press at one time. The first adsorption component 5 is used to take the finished product off the upper die 3, and the second adsorption component 6 is used to place the semi-finished product on the lower die 2. The function of such a setting is that during the hot pressing process, the second adsorption component 6 is filled with semi-finished products for feeding. When the previous group of semi-finished products is hot pressed, the upper die 3 is lifted, and then the loading plate 4 is placed in the gap between the upper die 3 and the lower die 2 through a reciprocating driving structure such as a robotic arm or a cylinder. Then, the loading plate 4 can also be controlled to move vertically upward through a reciprocating driving part such as a cylinder, so that the first adsorption component 5 contacts the finished product attached to the upper die 3 and adsorbs it on the first adsorption component 5. Then, the loading plate 4 is controlled to move downward, so that the semi-finished product on the second adsorption component 6 can be placed on the lower die 2. Then, the loading plate 4 is lifted upward by a small distance, so that the second adsorption component 6 is pulled out from the groove of the lower die 2 to complete the feeding of the semi-finished product. Then, the loading plate 4 is taken out from the gap between the upper die 3 and the lower die 2 (for the convenience of description, hereinafter referred to as the gap), so that the finished product can be driven to move synchronously to complete the unloading of the finished product (as Figure 2 shown). In this way, during the process of the first adsorption component 5 taking the finished product off the upper die 3, the semi-finished product is fed onto the lower die 2 through the second adsorption component 6, which can reduce the moving times of the loading plate 4, thereby improving the picking and placing efficiency of the hot pressing process.

[0038] Further, guide posts 7 are arranged on the body 1, and the upper die 3 is slidably connected to the guide posts 7. Specifically, there are four guide posts 7, and the four guide posts 7 are symmetrically arranged on the body 1. Slide holes adapted to the guide posts 7 are opened on the upper die 3, and through the sliding connection between the slide holes and the guide posts 7, the stability of the vertical movement of the upper die 3 can be improved.

[0039] Further, it further includes a hydraulic system for driving the vertical movement of the upper die 3. The hydraulic system is preferably a hydraulic cylinder, which is arranged at the top of the machine body 1, and its output end penetrates the top wall of the machine body 1 and is fixedly connected to the upper die 3. The hydraulic system can provide the power for the vertical movement of the upper die 3.

[0040] Further, the lower die 2 is slidably arranged on the machine body 1, and a power assembly for driving the vertical movement of the lower die 2 is arranged on the machine body 1. Specifically, in this embodiment, a lifting groove 8 adapted to the lower die 2 is formed on the machine body 1, and the lower die 2 is slidably connected to the lifting groove 8. The power assembly can be an existing reciprocating driving assembly such as an electric push rod, and its output end is connected to the lower die 2. The function of such a setting is that when the loading plate 4 is inserted into the gap and moved upward to remove the finished product, the power assembly controls the lower die 2 to move upward synchronously (the upward movement distance is greater than the upward movement distance of the loading plate 4). In this way, when the first adsorption assembly 5 contacts the finished product on the upper die 3, the lower die 2 contacts the semi-finished product on the second adsorption assembly 6, and the adsorption effect of the second adsorption assembly 6 is released. At this time, the semi-finished product will fall onto the lower die 2. Then, when controlling the downward movement of the loading plate 4, the power assembly controls the lower die 2 to move downward synchronously (the downward movement distance is also greater than the downward movement distance of the loading plate 4) to achieve avoidance, thereby saving the time for the above-mentioned downward movement of the loading plate 4 to drive the second adsorption assembly 6 to place the semi-finished product on the lower die 2 (as Figure 5 shown, that is, saving the time of Figure 2 the third step in

[0041] As another embodiment of the present invention, preferably, the power assembly includes a first toothed plate 9 fixedly connected to the lower die 2, a vertical rod 10 fixedly connected to the machine body 1, a second toothed plate 11 fixedly connected to the vertical rod 10, a connecting seat 12 slidably arranged on the vertical rod 10, a gear 13 rotatably arranged on the connecting seat 12, the gear 13 meshing with both the first toothed plate 9 and the second toothed plate 11 simultaneously, a connecting block 14 arranged on the feeding plate 4, and the connecting seat 12 being located on the movement stroke of the connecting block 14. Specifically, the vertical rod 10 is arranged on one side of the machine body 1 away from the feeding plate 4, and an installation groove 15 is formed inside the vertical rod 10. A connecting portion 16 is arranged on the lower die 2, the first toothed plate 9 is fixedly connected to the connecting portion 16, and the first toothed plate 9 is located inside the installation groove 15. Two through holes 17 for avoidance are formed on the side wall of the installation groove 15. The connecting seat 12 is integrally U-shaped, and the two sides of its U-shape are slidably connected to the through holes 17. The gear 13 is rotatably arranged inside the U-shape of the connecting seat 12. The second toothed plate 11 is fixedly connected to the inner wall of the installation groove 15. The first toothed plate 9 and the second toothed plate 11 are respectively located on both sides of the gear 13, and the first toothed plate 9 and the second toothed plate 11 are simultaneously meshed with the gear 13. The connecting block 14 is fixedly connected to the side surface of the feeding plate 4. A connecting groove 33 adapted to the connecting block 14 is formed on the connecting seat 12, and the connecting groove 33 is located on the movement stroke of the connecting block 14. The effect of such a setting is that during the process of the feeding plate 4 moving into the gap, the connecting block 14 will be inserted into the connecting groove 33. During the process of the feeding plate 4 moving upward to pick up the finished product, the connecting block 14 will drive the connecting seat 12 and the gear 13 to move upward synchronously. Since the gear 13 is simultaneously meshed with the first toothed plate 9 and the second toothed plate 11, and since the second toothed plate 11 is fixedly connected inside the installation groove 15, the upward movement of the connecting seat 12 will drive the gear 13 to rotate itself under the meshing action of the gear 13 and the second toothed plate 11. Also, because the gear 13 is also meshed with the first toothed plate 9, the upward movement distance of the first toothed plate 9 is twice the upward movement distance of the connecting seat 12 (i.e., the upward movement distance of the feeding plate 4). The advantage of such a setting is that when the feeding plate 4 moves upward to remove the finished product on the upper die 3, it will drive the lower die 2 to move upward passively by twice the distance, so that the semi-finished product on the second adsorption assembly 6 enters the groove of the lower die 2. At this time, the vacuum effect on the second adsorption assembly 6 is released, and the semi-finished product will fall into the lower die 2 to complete the passive feeding of the semi-finished product. When the finished product picking and semi-finished product feeding are completed, control the feeding plate 4 to move downward. At this time, the downward movement distance of the connecting seat 12 is also twice the downward movement distance of the feeding plate 4. In this way, the passive reset of the lower die 2 can be completed. Then control the feeding plate 4 to move horizontally to pull out the connecting block 14 from the connecting groove 33, thus completing the entire feeding and discharging process.

[0042] In the above technical solution, after the connecting block 14 and the connecting groove 33 are separated, the connecting seat 12 is in a movable state in the vertical direction, which also makes the lower die 2 in a movable state, reducing the stability of the lower die 2. Further, a passive limiting component for fixing the position of the lower die 2 is also included. Specifically, the passive limiting component can be a matching structure of a pin shaft and a linear reciprocating driving component such as a cylinder. When the connecting block 14 is not inserted into the connecting groove 33, the position of the connecting seat 12 is fixed by the pin shaft, so that the position of the lower die 2 can be fixed through transmission components such as the gear 13. After the connecting block 14 is inserted into the connecting groove 33, the pin shaft and the connecting seat 12 are controlled to be separated. At this time, when the loading plate 4 moves vertically, the lower die 2 can be driven to move vertically to improve the stability of the lower die 2.

[0043] As another embodiment of the present invention, preferably, the passive limiting component includes a limiting post 18. The connecting seat 12 includes a first section 19 and a second section 20 that are slidably connected, and a spring 21 is provided between the first section 19 and the second section 20. The limiting post 18 is fixedly connected to the first section 19. A limiting groove 22 adapted to the limiting post 18 is formed on the vertical rod 10, and the limiting post 18 is slidably connected to the limiting groove 22. Specifically, there are two second sections 20, which are located on two sides of the U-shaped connecting seat 12. A telescopic groove 23 is formed inside the second section 20. Two ends of the first section 19 are respectively slidably connected to the two telescopic grooves 23. One end of the spring 21 is fixedly connected to the end of the first section 19, and the other end is fixedly connected to the side wall of the telescopic groove 23. The gear 13 is rotatably arranged between the two second sections 20. The limiting post 18 is fixedly connected to the outer side wall of the connecting seat 12, and it is preferably cylindrical. The limiting groove 22 is formed on the side wall of the through hole 17, and it is preferably L-shaped, that is, the limiting groove 22 includes a horizontal side and a vertical side. The limiting post 18 is slidably connected to the limiting groove 22. The purpose of such a setting is that when the connecting block 14 is away from the connecting groove 33, the limiting post 18 is located in the horizontal side of the limiting groove 22, and under the elastic force of the spring 21, the limiting post 18 is located at the end of the horizontal side. At this time, under the limiting action of the limiting groove 22, the connecting seat 12 cannot move upward, so that the vertical direction of the lower die 2 can be limited. During the insertion process of the connecting block 14 into the connecting groove 33, it will push the first section 19 to move horizontally relative to the second section 20 and store energy in the spring 21, so that the limiting post 18 moves from the end of the horizontal side to the bottom end of the vertical side, that is, at this time the limiting post 18 is in a state where it can move vertically upward to realize the passive unlocking of the connecting seat 12. At this time, when controlling the connecting block 14 to move upward, the connecting seat 12 and the lower die 2 can be driven to move upward to complete subsequent material taking and placing. When the feeding plate 4 moves downward, it will drive the limiting post 18 to move to the bottom end of the vertical side of the limiting groove 22. At this time, control the connecting block 14 to be away from the connecting groove 33. At the same time, the elastic force of the spring 21 is released to drive the first section 19 to move horizontally in the reverse direction and synchronously drive the limiting post 18 to move to the end of the horizontal side of the limiting groove 22 to realize the passive reset of the connecting seat 12.

[0044] Preferably, a sealing portion 24 is provided on the lower die 2. Specifically, the sealing portion 24 has a cylindrical structure and is located at the bottom of the lower die 2, so that the space below the lower die 2 can be blocked during the upward movement of the lower die 2, thereby preventing impurities from entering.

[0045] Preferably, there are two limiting components, and the two limiting components are symmetrically arranged with respect to the connecting seat 12. The two limiting components can improve the stability of the connecting seat 12 during limiting.

[0046] When the semi-finished product is not completely placed in the groove of the lower mold 2, the hot pressing process will damage the semi-finished product, thereby reducing the qualified rate of the hot pressing process. As another embodiment of the present invention, a passive flattening assembly is provided between the machine body 1 and the lower mold 2. The passive flattening assembly includes a flattening rod 25 slidably disposed on the lower mold 2, a rotating seat 26 is provided on the machine body 1, and a connecting rod 27 is rotatably disposed between the rotating seat 26 and the flattening rod 25. Specifically, fixed shafts are provided inside the rotating seat 26 and at the end of the flattening rod 25, and the two ends of the connecting rod 27 are respectively rotatably connected to the two fixed shafts. A transverse groove 28 is formed on the upper surface of the lower mold 2, and a sliding portion 29 adapted to the transverse groove 28 is provided on the flattening rod 25. The sliding portion 29 is slidably connected to the transverse groove 28, and a limiting structure such as a convex portion is provided between the two to prevent them from separating from each other. There are two flattening rods 25, which are symmetrically arranged with respect to the lower mold 2. A roller 30 is rotatably disposed on the flattening rod 25. The roller 30 is located on the side of the flattening rod 25 close to the middle of the lower mold 2. The outer peripheral surface of the roller 30 is in contact with the upper surface of the lower mold 2, and the length of the flattening rod 25 is greater than the widths of the lower mold 2 and the upper mold 3. An avoidance groove 31 is provided in the middle of the upper mold 3. The function of such a setting is that when the upper mold 3 and the lower mold 2 are attached to perform hot pressing, the flattening rod 25 is located in the avoidance groove 31. After the hot pressing is completed, the upper mold 3 moves upward to open the gap. During the process of driving the lower mold 2 to move upward by the power assembly, the two flattening rods 25 will be pulled along the transverse groove 28 in a direction away from each other to a position close to both ends of the lower mold 2 under the action of the connecting rod 27 (and after the flattening rod 25 completely passes over the second adsorption assembly 6, the second adsorption assembly 6 will enter the groove of the lower mold 2 to avoid interference between the flattening rod 25 and the second adsorption assembly 6). When the finished product is taken and the semi-finished product is loaded, the lower mold 2 moves downward, and thus under the action of the connecting rod 27, the flattening rod 25 will be driven to slide along the transverse groove 28 in a direction close to each other, thereby driving the roller 30 to slide along the surface of the lower mold 2. At this time, the roller 30 will abut against the semi-finished product that is not completely placed in the groove to produce a flattening effect on the semi-finished product that is not placed stably, so as to improve the loading quality of the semi-finished product, thereby improving the qualified rate of the hot pressing process.

[0047] When the upper mold 3 moves upward to realize the blanking of the finished product, if the finished product falls on the lower mold 2, it will be damaged during the subsequent hot pressing process. Moreover, when the finished product falls into the groove, the subsequent hot pressing process will damage the finished product and the semi-finished product in the corresponding groove of the finished product synchronously. Preferably, an inclined surface 32 is provided on the flattening rod 25. Specifically, the inclined surface 32 is located on the opposite side of the roller 30. The function of such a setting is that when the lower mold 2 moves upward to drive the two flattening rods 25 to move away from each other, the inclined surface 32 of the flattening rod 25 will shovel the accidentally fallen finished product to both sides of the lower mold 2. On the one hand, it can avoid secondary hot pressing during the subsequent hot pressing process, and on the other hand, it can protect the semi-finished product in the groove, thereby further improving the yield rate of the hot pressing process.

[0048] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways.
