[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0023] Reference Figure 1-4This utility model discloses a double-flipping pulp molding machine, comprising a worktable 1, with a left plate 2 and a right plate 3 fixed at both ends of the top of the worktable 1, and a horizontal plate 4 fixed between the tops of the left plate 2 and the right plate 3. A placement frame 5 is fixed at the center of the top of the worktable 1, and a pulp tank 6 is disposed inside the placement frame 5. A first lifting mechanism is disposed on the right side of the left plate 2, and a second lifting mechanism is disposed on the left side of the right plate 3. A round shaft 7 is fixed on the left side of the second lifting mechanism, and a right connecting rod 8 is rotatably connected to the side of the round shaft 7. A drive motor 9 is rotatably connected to the right side of the first lifting mechanism, and a left connecting rod 10 is fixed to the side of the drive motor 9. Clamping frames 11 are fixed on the right side of the left connecting rod 10 and the left side of the right connecting rod 8. Two lower templates 12 are fixed between the two clamping frames 11. Multiple adsorption holes are opened on the top surface of the two lower templates 12 along the horizontal direction, and two lower connecting blocks 13 are fixed between the two lower templates 12. In the prior art... In the pulp molding process, a flipping technique is used to improve molding efficiency. However, currently, it is not possible to achieve double-sided flipping during the flipping process. Furthermore, the lower template is often suspended in mid-air during flipping, which can lead to instability and reduce molding efficiency. To address this issue, a drive motor 9 is rotatably connected to the right side of the first lifting mechanism. By starting the drive motor 9, and due to the rotatable connection between the right connecting rod 8 and the round shaft 7, the rotation of the drive motor 9 drives the left connecting rod 10, the right connecting rod 8, the clamping frame 11 between the left and right connecting rods 10 and 8, and the lower template 12 to rotate. This allows the two lower templates 12 to perform pulp suction molding and demolding operations respectively, improving molding efficiency. Moreover, since the two lower templates 12 are embedded inside the clamping frames 11 at both ends, the stability is enhanced during flipping.
[0024] The first and second lifting mechanisms include a first cylinder 14, with a slider 15 fixed to the bottom of the first cylinder 14. The left slider 15 is rotatably connected to the drive motor 9, and the right slider 15 is fixedly connected to the round shaft 7. An upper insert rod 16 is fixed to the bottom of the slider 15, and the bottom of the upper insert rod 16 is embedded in the inner side of the lower insert rod 17. Support blocks 18 are fixed to the bottom of the lower insert rods 17 at both ends, and the bottom of the support blocks 18 is fixedly connected to the top of the worktable 1. By activating the first cylinders 14 at both ends, the sliders 15 at both ends can move downwards by using the action of the upper insert rod 16 to move inwards to the inner side of the lower insert rod 17, thereby allowing the two lower templates 12 to be immersed in the pulp tank 6, so that multiple adsorption holes can adsorb and improve adsorption efficiency.
[0025] A second cylinder 19 is fixed at the top center of the horizontal plate 4. The output end of the second cylinder 19 extends to the bottom of the horizontal plate 4. A top rod 20 is fixed at the output end of the second cylinder 19. A top frame 21 is fixed at the bottom of the top rod 20. Upper templates 22 are fixed at both ends of the bottom side of the top frame 21. By activating the second cylinder 19, the top rod 20 moves the top frame 21 and the two upper templates 22 downwards, thereby enabling the upper templates 22 and the lower templates 12 to work together to press and shape the pulp.
[0026] The left plate 2 and the right plate 3 are provided with grooves 23 on opposite sides. The sliders 15 at both ends are slidably connected to the grooves 23. The sliders 15 can slide in the grooves 23 to enhance the stability of the lower template 12 when it moves down. A liquid discharge pipe 24 is fixed at the center of the back of the placement frame 5. The liquid discharge pipe 24 extends to the inside of the pulp tank 6. A valve body 25 is provided at the top of the liquid discharge pipe 24 to facilitate the release of the solution inside the pulp tank 6.
[0027] The interiors of both end frames 11 are smooth to prevent wear on the opposite sides of the two lower templates 12. The inside of the placement frame 5 is fixed with folding plates 26, and the outside of the pulp tank 6 is fixed with arc plates 27. The multiple arc plates 27 and folding plates 26 are connected by bolts 28, which can achieve the effect of reinforcing the pulp tank 6. The right connecting rod 8 and the left connecting rod 10 are both made of steel to improve the stability of the right connecting rod 8 and the left connecting rod 10 and enhance the flipping effect.
[0028] Working principle: First, pulp raw materials are poured into the pulp tank 6 and mixed with water to form a slurry. Auxiliary materials are added to improve fluidity. Then, by activating the first cylinders 14 at both ends, the sliders 15 at both ends are moved downwards by the action of the upper insert rod 16 moving inwards towards the lower insert rod 17. This allows the two lower templates 12 to be immersed in the pulp tank 6, enabling adsorption through multiple adsorption holes. Then, the drive motor 9 is activated. Due to the rotatable connection between the right connecting rod 8 and the round shaft 7, the rotation of the drive motor 9 drives the... The left connecting rod 10, the right connecting rod 8, and the clamping frame 11 and the lower template 12 between the left connecting rod 10 and the right connecting rod 8 are rotated, so that the two lower templates 12 can perform pulp suction forming and demolding operations respectively. Since the two lower templates 12 are embedded in the clamping frames 11 at both ends, the stability effect is enhanced when flipping. Finally, by activating the second cylinder 19, the top rod 20 is moved down with the top frame 21 and the two upper templates 22, so that the pulp can be pressed and formed by the combined action of the upper templates 22 and the lower templates 12.
[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
