This patent relates to the field of flattening devices and discloses a carton flattening device including a support plate. Open-top cartons for stacking are slidably mounted on the support plate. A driving component is fixedly mounted on the support plate via a mounting bracket. The driving component's drive rod is connected to a flattening mechanism for flattening and smoothing the stacked cartons. This patent, by incorporating a flattening mechanism, tightens the top cartons to both sides and then flattens them, improving the quality of the flattened cartons.

[0003] Although the aforementioned patent incorporates a flattening mechanism to tighten the top layer of the carton to both sides and flatten it, thereby improving the quality of the flattened product, its adaptability is somewhat lacking in practical use when dealing with cartons of different sizes. This makes it difficult for the patent to meet actual needs. Specifically, with smaller cartons, the device struggles to accurately position and flatten them; while with larger cartons, the limited flattening range may prevent complete coverage.

[0004] Therefore, it is necessary to modify the carton flattening device in the above patent to effectively prevent its lack of adaptability when facing cartons of different sizes, thus making it difficult to meet actual needs. Utility Model Content

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] like Figures 1 to 6 As shown, the carton flattening device in this embodiment includes a base 1. Support columns 2 are fixedly connected to the four corners of the top of the base 1. A support plate 3 is fixedly connected to the top of the support columns 2. A hydraulic telescopic rod 4 is fixedly connected to the top of the support plate 3. The output end of the hydraulic telescopic rod 4 passes through the support plate 3 and is fixedly connected to a sliding plate 5. Four sliding openings are provided on the surface of the sliding plate 5, and each of the four openings corresponds one-to-one with one of the four support columns 2 and is slidably connected to them. Limiting holes 6 are provided at the four corners of the surface of the sliding plate 5. Limiting columns 7 are slidably connected inside the limiting holes 6. A pressing plate 8 is fixedly connected to the bottom of the limiting columns 7. The pressing plate 8 is rectangular in shape, and its cross-sectional area is larger than the area of ​​the largest surface of a common carton. The top of the plate 8 has four transmission chambers 9, which are arranged in a ring. A lead screw 10 is rotatably connected inside the transmission chamber 9. The other end of the lead screw 10 passes through the pressure plate 8 and is fixedly connected to a servo motor 11. The housing of the servo motor 11 is fixedly connected to the pressure plate 8. A transmission bar 12 is threadedly connected to the surface of the lead screw 10. A sorting groove 13 is symmetrically opened on the top of the pressure plate 8 about the transmission chambers 9. A sorting bar 14 is slidably connected inside the sorting groove 13. The surface of the sorting bar 14 is fixedly connected to the end point of the transmission bar 12. A lifting groove 15 is opened at the bottom of the sorting bar 14. A lifting bar 16 is slidably connected inside the lifting groove 15. A control panel is provided on the surface of the base 1.

[0018] refer to Figure 2 and Figure 3 A buffer spring 17 is sleeved on the surface of the limiting post 7, and the buffer spring 17 is located between the support plate 3 and the pressure plate 8. A limiting block 18 is fixedly connected to the top of the limiting post 7, and the diameter of the limiting block 18 is larger than the diameter of the limiting hole 6.

[0019] In this embodiment, the buffer spring 17 can better adapt to cartons of different materials and thicknesses, making the flattening effect more uniform and flat, thus improving the recycling and storage value of the cartons. The limit block 18 can limit the maximum descent position of the pressing plate 8.

[0020] refer to Figure 6 The inner wall of the lifting groove 15 is symmetrically fixedly connected with a limiting block 19, and the surface of the lifting bar 16 is symmetrically provided with a limiting groove 20, and the inner wall of the limiting groove 20 is slidably connected to the surface of the limiting block 19.

[0021] In this embodiment, by setting the limiting block 19 and the limiting groove 20, the maximum lifting position of the lifting bar 16 can be limited, so as to prevent the lifting bar 16 from detaching from the lifting groove 15.

[0022] refer to Figure 4 and Figure 6 The top of the pressing plate 8 is fixedly connected to a bearing column 21, and the height of the bearing column 21 is greater than the height of the sorting strip 14. An auxiliary groove 22 is provided on the inner wall of the sorting groove 13. An auxiliary block 23 is fixedly connected to the surface of the sorting strip 14, and the surface of the auxiliary block 23 is slidably connected to the inner wall of the auxiliary groove 22.

[0023] In this embodiment, the arrangement bar 14 can be protected by the support column 21 to prevent it from being squeezed by the slide plate 5 and damaged. The auxiliary groove 22 and the auxiliary block 23 can restrict the arrangement bar 14 to only linear movement to prevent it from tilting or deviating.

[0024] refer to Figure 1 and Figure 5 A connecting plate 24 is fixedly connected to one side of the base 1. An electric push rod 25 is fixedly connected to the outside of the connecting plate 24. A push plate 26 is fixedly connected to the output end of the electric push rod 25. The position of the push plate 26 does not contact the servo motor 11. An inclined groove is fixedly connected to the other side of the base 1. A guide channel 27 is fixedly connected to the outside of the inclined groove.

[0025] This embodiment, through the arrangement of connecting plate 24, electric push rod 25, push plate 26, tilting groove and guide channel 27, can push the flattened carton out of the flattening device, so that it can be centrally stored by the external storage device, so as to facilitate the subsequent recycling and storage of the carton.

[0026] refer to Figure 1 Both the top of the base 1 and the bottom of the pressure plate 8 are fixedly connected with buffer pads, and the cross-sectional area of ​​the lower buffer pad is greater than that of the upper buffer pad.

[0027] This embodiment, through the setting of a cushioning pad, effectively avoids scratches and damage to the surface of the carton while ensuring flattening, and is more suitable for some cartons with printed surfaces or special materials.

[0028] The cardboard box is placed centered on the cushioning pad on the base 1. Then, the hydraulic telescopic rod 4 is activated via the control panel to drive the sliding plate 5 to descend synchronously, positioning the pressing plate 8 above the cardboard box. At this point, the lifting bar 16 falls naturally under gravity. Then, the servo motor 11 is activated to drive the lead screw 10 to rotate, which in turn drives the transmission bar 12 to slide within the transmission cavity 9. This allows the sorting bar 14 to move closer to the cardboard box, enabling the lifting bar 16 to quickly and easily adapt to cardboard boxes of different sizes, thus limiting its movement and preventing the cardboard box from tilting during pressing. Then, the hydraulic telescopic rod 4 is activated again to drive the pressing plate 8 to descend, allowing the limiting post 7 to slide upward within the limiting hole 6, compressing the cushioning spring 17. This, combined with the cushioning pad, better adapts to different sizes of cardboard boxes. Using cartons of the same material and thickness ensures a more uniform and flat flattening effect, enhancing the recycling and storage value of the cartons. The bearing column 21 on the pressing plate 8 contacts the sliding plate 5, allowing the pressing plate 8 to flatten the cartons. At this point, the lifting bar 16 presses against the lower buffer pad, retracting the cartons into the sorting trough 13 for storage. After flattening, the hydraulic telescopic rod 4 is activated to return the pressing plate 8 to its original position. Then, the electric push rod 25 is activated to move the cartons horizontally, allowing them to be pushed out of the flattening device through the guide channel 27 and centrally stored by the external storage device. This allows the flattening device to quickly adapt to cartons of different sizes, effectively flattening both small express cartons and large industrial packaging cartons, thus expanding its application range.
