Technical Field

[0001] The present invention relates to the technical field of paper cup production, in particular to a double-layer paper cup preparation device. Background Art

[0002] Paper cups are disposable daily necessities. They are widely used in the market because of their convenience, cleanliness and hygiene. Paper cups are a kind of paper container made by mechanically processing and gluing base paper made from chemical wood pulp. They have a cup-shaped appearance.

[0003] Existing paper cup production equipment usually adopts an intermittent production method when producing paper cups. The production cycle of each paper cup is relatively long, which not only increases production costs but also limits the expansion of production scale. In addition, when preparing double-layer paper cups, it takes time to replace the mold, resulting in low production efficiency.

[0004] Therefore, it is necessary to provide a double-layer paper cup preparation device to solve the above technical problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a double-layer paper cup preparation device to solve the problems existing in the above-mentioned background technology. The technical solution of the present invention addresses the technical problem that the existing technical solution is too single and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: A double-layer paper cup preparation device comprises a circular structure base plate, support rods are equidistantly installed on the outer side of the top of the base plate, the top of the support rods supports a supporting circular plate, the top center of the supporting circular plate is installed with a support seat, the top of the support seat is rotatably connected to the top of the circular structure top plate, a fixed mold is equidistantly penetrated through the outer side of the top of the top plate, an annular seat extending to the bottom of the fixed mold is equidistantly installed on the outer side of the top of the base plate, a fixed seat is equidistantly installed on the outer side of the top of the supporting circular plate, and a movable mold that can move up and down is installed on the inner top of the fixed seat.

[0007] Preferably, a telescopic rod is installed on the inner top of the fixing seat, a connecting circular plate is installed on the telescopic end of the telescopic rod, and the bottom of the connecting circular plate is connected to the movable mold.

[0008] Preferably, a mold cavity is opened inside the fixed mold, and the diameters of adjacent mold cavities are different, while the diameters of interval mold cavities are the same.

[0009] Preferably, an arc-shaped telescopic tube is installed on the outer side of the top of the connecting circular plate, and a connecting hole connected to the arc-shaped telescopic tube is opened inside the connecting circular plate, and an arc-shaped hole penetrating into the mold cavity is opened on the outer side of the top of the fixed mold.

[0010] Preferably, a hydraulic rod is installed at the inner bottom end of the annular seat, a movable plate is connected to the top of the hydraulic rod, a bottom plate adapted to the diameter of the mold cavity is installed at the top center of the movable plate, cooling pipes are equidistantly installed on the outer side of the top of the movable plate, and bottom grooves adapted to the cooling pipes are equidistantly opened on the outer side of the bottom of the fixed mold.

[0011] Preferably, an annular groove is provided inside the movable plate, and the annular groove is connected to the cooling pipe.

[0012] Preferably, gear blocks are equidistantly installed on the outer side of the top plate, an arc-shaped seat is installed on the outer side of the supporting circular plate, a driving device is installed on the top of the arc-shaped seat, and a gear meshing with the gear blocks is installed on the top of the driving device.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the staff controls the extension of the telescopic rod to move the connecting circular plate to the top of the fixed mold, and then moves the movable mold into the mold cavity. After the movable mold enters the fixed mold, the staff controls the extension of the hydraulic rod to move the movable plate upward until the bottom plate moves into the mold cavity and has a certain gap with the bottom of the movable mold. At this time, the movable mold, the fixed mold and the bottom plate are combined to form a casting gap for the paper cup. When the bottom plate enters the mold cavity, the cooling pipe will simultaneously enter the bottom trough, thereby cooling and shaping the paper cup and accelerating the molding effect. The present invention injects raw materials for preparing paper cups into the communicating hole through an arc-shaped telescopic tube, and then enters the mold cavity through the arc-shaped hole for molding. The provision of the arc-shaped telescopic tube does not affect the up and down movement of the connecting circular plate. By setting adjacent mold cavities of different diameters and setting the interval mold cavities of the same diameter, the inner diameters of the gaps generated by the cooperation between the movable mold and the fixed mold are different. This can be used to prepare a single-layer structure of a paper cup inside a fixed mold with a smaller inner diameter of the gap. After the single-layer structure of the paper cup is formed, the material will adhere to the outer wall of the movable mold due to the characteristics of the material. Then, by rotating the top plate, the movable mold is moved to the mold cavity with a larger inner diameter of the gap. At this time, the second layer structure of the paper cup can be prepared, thereby realizing the simultaneous preparation of double-layer structures of multiple paper cups and reducing the time used to prepare double-layer structure paper cups.

[0019] like Figure 1-6 As shown, a telescopic rod 10 is installed on the inner top of the fixed seat 8, and a connecting circular plate 11 is installed on the telescopic end of the telescopic rod 10. The bottom of the connecting circular plate 11 is connected to the movable mold 9. By using the telescopic rod 10 to control the up and down movement of the connecting circular plate 11, the up and down movement of the movable mold 9 can be controlled, and then the coordination between the movable mold 9 and the fixed mold 6 can be controlled.

[0020] like Figure 1-6 As shown, a mold cavity is opened inside the fixed mold 6, and the diameters of adjacent mold cavities are different, and the diameters of the interval mold cavities are the same. By setting the diameters of adjacent mold cavities to be different and the diameters of the interval mold cavities to be the same, the inner diameters of the gaps generated by the cooperation between the movable mold 9 and the fixed mold 6 are different, which can be used to prepare a single-layer structure of a paper cup inside a fixed mold 6 with a smaller inner diameter of the gap. After the single-layer structure of the paper cup is prepared, it will adhere to the outer wall of the movable mold 9 due to the characteristics of the material. Then, the movable mold 9 is moved to the inside of the mold cavity with a larger inner diameter of the gap by rotating the top plate 5. At this time, the second layer structure of the paper cup can be prepared, thereby realizing the simultaneous preparation of double-layer structures of multiple paper cups and reducing the time used to prepare double-layer structure paper cups.

[0021] like Figure 1-6 As shown, an arc-shaped telescopic tube 12 is installed on the outer side of the top of the connecting circular plate 11, and a connecting hole 13 connected to the arc-shaped telescopic tube 12 is opened inside the connecting circular plate 11. An arc-shaped hole 14 that penetrates into the mold cavity is opened on the outer side of the top of the fixed mold 6. The raw materials for making paper cups can be injected into the connecting hole 13 through the arc-shaped telescopic tube 12, and then enter the mold cavity through the arc-shaped hole 14 for molding. The arrangement of the arc-shaped telescopic tube 12 will not affect the up and down movement of the connecting circular plate 11.

[0022] like Figure 1-6As shown, a hydraulic rod 15 is installed at the inner bottom end of the circular ring seat 7, and a movable plate 16 is connected to the top of the hydraulic rod 15. A bottom plate 17 adapted to the diameter of the mold cavity is installed at the top center of the movable plate 16, and cooling pipes 18 are equidistantly installed on the outer side of the top of the movable plate 16. Bottom grooves 19 adapted to the cooling pipes 18 are equidistantly opened on the outer side of the bottom of the fixed mold 6. After the movable mold 9 enters the fixed mold 6, the staff controls the hydraulic rod 15 to extend and move the movable plate 16 upward until the bottom plate 17 moves to the inside of the mold cavity and has a certain gap with the bottom of the movable mold 9. At this time, the movable mold 9, the fixed mold 6 and the bottom plate 17 are combined into a casting gap for the paper cup. When the bottom plate 17 enters the mold cavity, the cooling pipes 18 are synchronously entered into the bottom groove 19, thereby cooling and shaping the paper cup and accelerating the molding effect.

[0023] like Figure 1-6 As shown, a circular groove 20 is provided inside the movable plate 16, and the circular groove 20 is connected to the cooling pipe 18. The circular groove 20 is provided so that a connecting structure is formed between the cooling pipes 18. The coolant can be introduced into the interior of the circular groove 20 through the existing technology, and a through hole can be opened at the bottom of the circular groove 20 to connect the connecting hose that passes through the circular seat 7.

[0024] like Figure 1-6 As shown, gear blocks 21 are installed at equal distances on the outer side of the top plate 5, an arc-shaped seat 22 is installed on the outer side of the supporting circular plate 3, a driving device 23 is installed on the top of the arc-shaped seat 22, and a gear 24 meshing with the gear block 21 is installed on the top of the driving device 23. The set driving device 23 can control the rotation of the gear 24 and then mesh with the gear block 21 to control the rotation of the top plate 5.

[0025] Working principle: When in use, the staff first controls the telescopic rod 10 to extend and move the connecting circular plate 11 to the top of the fixed mold 6. At this time, the movable mold 9 is moved into the mold cavity. After the movable mold 9 enters the fixed mold 6, the staff controls the hydraulic rod 15 to extend and move the movable plate 16 upward until the bottom plate 17 moves into the mold cavity and has a certain gap with the bottom of the movable mold 9. At this time, the movable mold 9, the fixed mold 6 and the bottom plate 17 are combined into a casting gap for the paper cup. When the bottom plate 17 enters the mold cavity, the cooling pipe 18 is synchronously entered into the bottom groove 19, thereby cooling and shaping the paper cup and accelerating the molding effect. Then, the raw materials for preparing the paper cup can be injected into the connecting hole 13 through the arc telescopic tube 12. The shaped hole 14 enters the mold cavity for molding, and the arrangement of the arc-shaped telescopic tube 12 will not affect the up and down movement of the connecting circular plate 11. By setting the adjacent mold cavities with different diameters and the interval mold cavities with the same diameter, the inner diameters of the gaps generated by the cooperation of the movable mold 9 and the fixed mold 6 are different, which can be used to prepare a single-layer structure of a paper cup inside a fixed mold 6 with a smaller inner diameter of the gap. After the single-layer structure of the paper cup is ready, it will adhere to the outer wall of the movable mold 9 due to the characteristics of the material. Then, the movable mold 9 is moved to the mold cavity with a larger inner diameter of the gap by rotating the top plate 5. At this time, the second layer structure of the paper cup can be prepared, thereby realizing the preparation of a double-layer structure of multiple paper cups simultaneously and reducing the time used to prepare the double-layer structure paper cup.
