Specific implementation manner

[0018] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0019] Please refer to Figures 1-3 , the present utility model provides a technical solution: a flattening device for producing packaging cartons, including a frame 1, the frame 1 includes a conveyor belt 20 for conveying cardboard and a workbench 21 for flattening cardboard, the workbench 21 is arranged at the rear side of the conveyor belt 20, a support table 4 is arranged on the front side of the frame 1 in a liftable manner, a placement rack 5 for placing cardboard is arranged on the support table 4, both sides of the front end of the frame 1 are fixedly connected with support frames 6, a moving plate 9 is arranged between the two support frames 6 in a movable manner back and forth, and a plurality of vacuum suction cups 11 for sucking cardboard and placing it on the conveyor belt 20 are arranged in the middle of the moving plate 9 in a liftable manner, and brushes 12 for cleaning the upper and lower surfaces of the cardboard are arranged at the top and bottom of the frame 1 and at the rear side of the support frames 6.

[0020] The conveyor belt 20 is a multi-strip conveyor belt 20, and gaps are arranged in the middle of the multi-strip conveyor belt 20 to ensure that the brush 12 can clean the cardboard, ensure that there are no impurities remaining on the cardboard, and can also be used for storage in multiple gaps to further store the impurities.

[0021] The vacuum suction cup 11 generates negative pressure inside the vacuum suction cup 11 through a vacuum pump device, so that the vacuum suction cup 11 can firmly adsorb the cardboard. By controlling the vacuum pump device, the negative pressure state inside the vacuum suction cup 11 is released, the suction of the cardboard is released, and the cardboard is placed on the conveyor belt 20.

[0022] In this embodiment, the height of the support table 4 is adjusted to make the height of the cardboard on the placement rack 5 match that of the vacuum suction cup 11. The moving plate 9 moves forward so that the vacuum suction cup 11 aligns with the cardboard on the placement rack 5. The vacuum suction cup 11 descends to suck the cardboard, then ascends and moves backward with the moving plate 9. When the moving plate 9 moves the cardboard above the conveyor belt 20, the vacuum suction cup 11 releases the cardboard, causing it to fall onto the conveyor belt 20. The conveyor belt 20 starts to operate, and the upper and lower surfaces of the cardboard are cleaned by the brush 12, and then the cardboard is conveyed to the flattening workbench 21, where the cardboard is flattened to remove the wrinkles and unevenness on its surface.

[0023] Further, both ends of the front side of the frame 1 are fixedly connected with support plates 2, and hydraulic cylinders 3 are arranged on the tops of the two support plates 2. The support table 4 is fixedly connected to the tops of the two hydraulic cylinders 3.

[0024] In this embodiment, the two hydraulic cylinders 3 can be guaranteed to run synchronously through system control.

[0025] The hydraulic cylinder 3 drives the support table 4 to move slowly upward to ensure that the vacuum suction cup 11 can adsorb the cardboard on the placement rack 5 for processing.

[0026] Further, on one side of the top of a support frame 6, an installation box 16 is transversely arranged. One end of the installation box 16 is fixedly connected with a motor 7. The output end of the motor 7 is fixedly connected with a lead screw 17. A threaded sleeve 15 is threadedly connected to the surface of the lead screw 17. A connecting rod 8 is fixedly connected to the surface of the threaded sleeve 15. One side of the moving plate 9 is fixedly connected with the connecting rod 8.

[0027] In this embodiment, when placing the cardboard on the conveyor belt 20, the first motor 7 is controlled to drive the lead screw 17 to rotate. Due to the threaded connection between the threaded sleeve 15 and the lead screw 17, the rotation of the lead screw 17 is converted into the linear movement of the threaded sleeve 15. The linear movement of the threaded sleeve 15 is transmitted to the moving plate 9 through the connecting rod 8, so that the moving plate 9 moves back and forth under the guidance of the support frame 6, thereby ensuring the stability of the movement of the vacuum suction cup 11 during the feeding process.

[0028] Further, a slide rail 18 is fixedly connected to the top of the other support frame 6. A slider 19 is slidably arranged on the surface of the slide rail 18. The other side of the moving plate 9 is fixedly connected with the slider 19.

[0029] In this embodiment, the cooperation between the slide rail 18 and the slider 19 can ensure the stability and smoothness of the moving plate 9 during the movement, and it also serves as an auxiliary device for the motor 7 and the lead screw 17.

[0030] Furthermore, an electric telescopic rod 10 is fixedly connected to the middle of the movable plate 9, a support plate 13 is fixedly connected to the bottom of the electric telescopic rod 10, and a plurality of vacuum suction cups 11 are fixedly connected to the bottom of the support plate 13 and are distributed in a ring-shaped manner.

[0031] In this embodiment, when it is necessary to adsorb the cardboard, the electric telescopic rod 10 is first controlled to extend downward. The extension of the electric telescopic rod 10 drives the vacuum suction cup 11 to move downward until the vacuum suction cup 11 is in close contact with the cardboard. A negative pressure is generated inside the vacuum suction cup 11 by the vacuum pump device, so that the vacuum suction cup 11 can firmly adsorb the cardboard. After the vacuum suction cup 11 successfully adsorbs the cardboard, the movable plate 9 is controlled to move backward to move the cardboard from one place to another. When the cardboard needs to be released, the negative pressure state inside the vacuum suction cup 11 is released by controlling the vacuum pump device, and the electric telescopic rod 10 is started again to shorten it upward, driving the vacuum suction cup 11 to separate from the cardboard.

[0032] Furthermore, a flattening assembly 14 for flattening the cardboard is provided above the workbench 21.

[0033] In this embodiment, the flattening assembly 14 is a prior art and will not be described in detail.

[0034] Working principle and use process of the utility model: After the utility model is installed, the height of the support table 4 is adjusted to match the height of the cardboard on the placement rack 5 with the height of the vacuum suction cup 11, the moving plate 9 moves forward, the vacuum suction cup 11 is aligned with the cardboard on the placement rack 5, the vacuum suction cup 11 descends and absorbs the cardboard, then rises and moves backward with the moving plate 9, when the moving plate 9 moves the cardboard above the conveyor belt 20, the vacuum suction cup 11 releases the cardboard and makes it fall on the conveyor belt 20. The conveyor belt 20 starts to run, the upper and lower surfaces of the cardboard are cleaned by the brush 12, and then the cardboard is transported to the flattening workbench 21, and the cardboard is flattened on the flattening workbench 21.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
