[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0022] like Figures 1 to 5 As shown, a double-headed paper-plastic molding machine is characterized by comprising a frame 1, a slurry pool 2 on the upper side of the frame 1, a vertically movable intermediate cooling extrusion die 3 within the slurry pool 2, a transverse moving structure 4 with a column 11 fixed to the upper side of the slurry pool 2, a hot pressing upper die 5 on the lower side of the transverse moving structure 4, a hot pressing lower die 6 on the side of the slurry pool 2, a hot pressing drive structure 7 on the lower side of the hot pressing lower die 6 for driving the hot pressing lower die 6 to move vertically, the hot pressing upper die 5 moving back and forth between the upper side of the intermediate cooling extrusion die 3 and the upper side of the hot pressing lower die 6 under the action of the transverse moving structure 4, a vacuum generator connected to the cavity of the hot pressing upper die 5, and a material receiving structure 8 for discharging material on the outer side of the hot pressing lower die 6.
[0023] By setting the upper hot press die 5 to move laterally, after the slurry is sucked up by the intermediate cooling die 3, the slurry moisture can be initially extruded to form a wet blank during the pressing process with the upper hot press die 5. Then, the upper hot press die 5 moves to the upper position of the lower hot press die 6. After the upper hot press die 5 and the lower hot press die 6 are pressed together, the moisture in the wet blank can be removed, thereby obtaining the desired product. In this way, multiple actions are completed by the upper hot press die 5, thereby simplifying the overall function of the equipment and reducing production costs.
[0024] At this point, in order for the hot pressing upper die 5 to move the wet blank during the movement, the cavity of the hot pressing upper die 5 needs to be connected to a vacuum generator. That is, after the hot pressing upper die 5 and the intermediate cold extrusion die 3 are pressed together to form a wet blank, the vacuum generator is activated, and a vacuum is formed in the cavity of the hot pressing upper die 5. In this way, after the hot pressing upper die 5 and the intermediate cold extrusion die 3 are opened, the wet blank can be vacuum-adsorbed and fixed at the lower side of the hot pressing upper die 5. In this way, during the movement of the hot pressing upper die 5, the wet blank can be moved and then moved to the position of the hot pressing upper die 5 and the hot pressing lower die 6 to complete the subsequent hot pressing process. Therefore, there is no need to set up a separate moving structure and a cold extrusion upper die. The hot pressing upper die 5 can perform the functions of the cold extrusion upper die and the moving structure, thereby improving production efficiency and reducing equipment costs.
[0025] At this time, because the time required in the process of hot pressing the upper die 5 and the lower die 6 is relatively long, the hot pressing process is longer than the cold extrusion process in time, in order to improve the production efficiency, the hot pressing at this time is provided with two stations, which are located at both sides of the slurry pool 2, specifically, in the embodiment, the hot pressing lower die 6 is provided with two, including the first hot pressing lower die 61 and the second hot pressing lower die 62, which are located at both sides of the middle cold extrusion die 3, the hot pressing upper die 5 is provided with two, including the first hot pressing upper die 51 and the second hot pressing upper die 52, which are arranged on the upper side of the corresponding hot pressing lower die 6 through the transverse moving structure 4, under the action of the transverse moving structure 4, the first hot pressing upper die 51 moves on the upper side of the first hot pressing lower die 61 and the middle cold extrusion die 3, and the second hot pressing upper die 52 moves on the upper side of the second hot pressing lower die 62 and the middle cold extrusion die 3. That is, the middle cold extrusion die 3 is arranged at the middle position of the workbench, the first hot pressing lower die 61 and the second hot pressing lower die 62 are arranged at both sides, and the first hot pressing upper die 51 and the second hot pressing upper die 52 are arranged on the upper side correspondingly, under the action of the transverse moving structure, the first hot pressing upper die 51 moves on the upper side of the first hot pressing lower die 61 and the middle cold extrusion die 3, and the second hot pressing upper die 52 moves on the upper side of the second hot pressing lower die 62 and the middle cold extrusion die 3, so that one slurry pool 2, a middle cold extrusion die 3 and then two hot pressing stations are arranged, which can improve the production efficiency.
[0026] For the movement of the first hot pressing upper die 51 and the second hot pressing upper die 52, in the embodiment, the rack 1 includes a workbench, the upper side of the workbench is provided with an upper support 12 through a vertical column 11, the transverse moving structure 4 includes a transverse guide rail 41 arranged at the bottom position of the upper support 12, the hot pressing upper die 5 is arranged at the lower side of the transverse guide rail 41 through a sliding block, and the lower side of the upper support 12 is provided with a transverse driving structure 42 for controlling the movement of the hot pressing upper die 5. Under the action of the transverse driving structure 42, the first hot pressing upper die 51 and the second hot pressing upper die 52 move, at this time, the middle cold extrusion die 3 and the hot pressing lower die 6 move up and down are controlled separately. Thus, the wet blank making and hot pressing process are completed.
[0027] Specifically, the transverse driving mechanism comprises a first motor 421 and a second motor 422, the first motor 421 and the second motor 422 are respectively located at two ends of the upper support 12, the first motor 421 is connected with a first screw rod 431, the second motor 422 is connected with a second screw rod 432, the ends of the first screw rod 431 and the second screw rod 432 are located on the upper side of the middle cold extrusion die 3, and the ends of the first screw rod 431 and the second screw rod 432 abut, the first hot pressing upper die 51 and the second hot pressing upper die 52 are respectively connected with the first screw rod 431 and the second screw rod 432 through a moving pair. At this time, the first hot pressing upper die 51 and the second hot pressing upper die 52 are controlled through two motors and two screw rods, so that the first hot pressing upper die 51 and the second hot pressing upper die 52 can be controlled individually in the process of use. Since the end positions of the first screw rod 431 and the second screw rod 432 abut (close, have a certain interval, and do not affect each other), and are respectively fixed with the upper support 12 through the support seat, the abutment positions are located on the upper side of the middle point of the middle cold extrusion die 3. Therefore, in order to make the first hot pressing die and the second hot pressing die move to the upper side of the middle cold extrusion die 3 and be able to be folded with the middle cold extrusion die 3, the first hot pressing die and the second hot pressing die need to be moved to the same position. Therefore, at this time, the moving pairs, to which the first hot pressing die and the second hot pressing die are connected with the first screw rod 431 and the second screw rod 432, are respectively close to the outer sides of the first hot pressing die and the second hot pressing die, that is, away from the position of the middle cold extrusion die 3. Therefore, in the process of moving the first hot pressing die and the second hot pressing die, they can all be moved to the upper side of the middle cold extrusion die 3, so as to realize the production of the wet blank.
[0028] After the production of the wet blank is completed, the hot pressing upper die 5 moves to the upper side of the hot pressing lower die 6, then the hot pressing lower die 6 moves upward to be folded with the hot pressing upper die 5 to complete hot pressing. Therefore, it is necessary to control the upward and downward movement of the hot pressing lower die 6 at this time. In the embodiment, a vertical guide rod 13 is arranged between the workbench and the upper support 12, the hot pressing lower die 6 is slidably connected with the vertical guide rod 13 through a linear bearing 63, and a lower driving structure for driving the upward and downward movement of the hot pressing lower die 6 is arranged on the lower side of the hot pressing lower die 6. Under the action of the vertical guide rod 13, the hot pressing lower die 6 moves upward and downward along the vertical guide rod 13. At this time, the lower driving structure adopts a pneumatic cylinder or a hydraulic cylinder for controlling the upward and downward movement of the hot pressing lower die 6,
[0029] For the hot-pressing lower die 6, it is mainly used for hot-pressing forming with the hot-pressing upper die 5, so in the embodiment, the hot-pressing lower die 6 comprises a die part 641 at the middle position, four corner positions of the die part 641 are connected with a moving sleeve 643 through a connecting part 642, the moving sleeve 643 is connected with the vertical guide rod 13 through a linear bearing 63, and the die part 641, the connecting part 642 and the moving sleeve 643 are integrally formed. At this time, the middle position of the hot-pressing lower die 6 is the die part 641, which is rectangular, and the die part 641 is connected with the vertical guide rod 13 through the connecting part 642 and the moving sleeve 643 at the four corner positions respectively, so that the overall weight of the hot-pressing lower die 6 is greatly reduced, the required power is reduced during the movement of the hot-pressing lower die 6, and thus a smaller power mechanism can be selected to drive the hot-pressing lower die 6 to move up and down, thereby reducing the production cost.
[0030] After the hot-pressing upper die 5 and the hot-pressing lower die 6 are positioned to complete the hot-pressing, the product needs to be taken out, and in the embodiment, the taking structure 8 comprises a side frame 81, a horizontal moving structure 82 is arranged at the side edge position of the side frame 81, a vertical moving structure 83 moving horizontally is arranged outside the horizontal moving structure 82, a fixed plate 84 moving up and down is arranged at the side edge of the vertical moving structure 83, a conveying assembly 85 is arranged at the upper side of the fixed plate 84, and the conveying assembly 85 moves to the position between the hot-pressing upper die 5 and the hot-pressing lower die 6 under the action of the horizontal moving structure 82 and the vertical moving structure 83. Since the cavity of the hot-pressing upper die 5 is connected with the vacuum generator, after the hot-pressing is completed, the vacuum generator is started, so that the product is adsorbed at the lower side position of the hot-pressing upper die 5, and then under the left and right action of the vertical moving structure 83 and the horizontal moving structure 82, the conveying assembly 85 moves to the lower side position of the hot-pressing upper die 5, and then the hot-pressing upper die 5 is controlled to place the product at the bottom position on the upper side of the conveying assembly 85, and then the conveying assembly 85 is moved out of the position of the hot-pressing upper die 5 under the action of the vertical moving structure 83 and the horizontal moving structure 82. At this time, the conveying assembly 85 can be moved to the lower side position of the hot-pressing upper die 5 under the action of the vertical moving structure 83 and the horizontal moving structure 82, so that the product after hot-pressing is conveniently taken out, and at the same time, after being taken out, the product can be taken out under the action of the conveying assembly 85, thereby completing the production process of the paper plastic.
[0031] Specific, the conveying assembly 85 includes a conveyor belt, both sides of the conveyor belt are provided with fixed rod, both ends of the fixed rod are provided with rotating shaft, rotating shaft is located inside the conveyor belt, the lower side of the rotating shaft is connected with the fixed plate 84 through the fixed support, the rotating shaft is connected with the motor, for controlling the rotation of the rotating shaft, at this time, the fixed support is used for supporting the fixed rod on both sides, so that the end of the conveyor belt is in a suspended state, so that the end of the conveyor belt moves to the lower side of the hot pressing upper die 5, the hot pressing upper die 5 and the hot pressing lower die 6 do not collide, so as to ensure that the conveying assembly 85 and the hot pressing upper die 5 and the hot pressing lower die 6 are used normally.
[0032] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present disclosure.
[0033] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
