[0002] Ton bag packaging boxes are used to store ton bags filled with powder. The bottom of the ton bag packaging box is usually provided with a leakage hole. After the external bag rupture head passes through the leakage hole from bottom to top and punctures the ton bag, the powder inside the ton bag will be discharged downwards through the leakage hole of the ton bag packaging box.

[0003] However, when existing ton bag packaging boxes are used with bag-breaking heads, powder often remains inside the ton bag. Even with the addition of a vibration device, it is impossible to fully and quickly release the powder from the ton bag, which urgently needs improvement. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a packaging box with a flap that can fully and quickly release the powder from the ton bag.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a packaging box with flaps, comprising: side plates arranged around the perimeter, a bottom plate disposed on the bottom side of the side plates and forming a receiving cavity for placing ton bags together with the side plates, and a plurality of flaps disposed in the receiving cavity and located on the bottom plate; the bottom plate and the flaps are provided with a leakage hole in the middle for the powder in the ton bag to leak outward; the side of the flap away from the leakage hole is a free end, and when the free end is raised, the flap forms a slope inclined towards the leakage hole.

[0006] The present invention is further provided that the flap is rotatably mounted on the side of the base plate near the material leakage hole via a rotating shaft.

[0007] The present invention is further provided that the base plate has a top plate hole corresponding to each of the flaps, and the top plate hole is located on the side of the base plate away from the rotating shaft.

[0008] The present invention is further provided that the base plate has 2N top plate holes, and each flap has two top plate holes.

[0009] The present invention further includes a base frame for supporting the base plate on its lower side, the base frame avoiding the hole in the top plate.

[0010] The present invention is further provided that the base plate and the material leakage hole have an arc-shaped transition.

[0011] The present invention further provides that the inner bottom wall of the base plate is provided with a plurality of grooves communicating with the material leakage hole, and each groove corresponds to the installation of a flap; when the flap is flat, the flap exactly fills the groove.

[0012] The present invention is further provided that the outer contour of the inner bottom wall of the base plate is square, and a groove is provided between each side of the inner bottom wall of the base plate and the material leakage hole; when the four flip plates are raised, they together form a gathering cavity.

[0013] The present invention is further provided that the flap is trapezoidal, with the side of the flap closer to the discharge hole being the short side and the side farther from the discharge hole being the long side, and the two inclined sides connecting the short side and the long side being mirror-symmetrically arranged.

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0026] This embodiment relates to a packaging box with a flap, such as... Figures 1-3 As shown, the device includes: a side plate 100 arranged around the perimeter; a bottom plate 200 disposed on the bottom side of the side plate 100 and forming a receiving cavity for placing the ton bag together with the side plate 100; and a plurality of flaps 300 disposed within the receiving cavity and located on the bottom plate 200. A leakage hole 211 for the powder inside the ton bag to leak outwards is provided in the middle of the bottom plate 200 and the flaps 300. The side of the flap 300 away from the leakage hole 211 is a free end; when this free end is raised, the flap 300 forms a slope inclined towards the leakage hole 211.

[0027] By setting multiple flaps 300 on the base plate 200, the flaps 300 can be lifted away from the discharge hole 211, causing the multiple flaps 300 to converge and form a slope to guide the discharge hole 211, which helps to fully and quickly release the powder in the ton bag. When the flaps 300 are in a flat position, there is more space in the receiving cavity to accommodate the ton bag, so the packaging box can be adapted to accommodate ton bags containing more powder. After the powder in the ton bag is partially released, the powder can be further released by lifting the flaps 300 to form a slope.

[0028] In this embodiment, there are four side plates 100, which form a frame with a square cross-section. In addition to the base plate body 210, the base plate 200 also has base plate walls 220 surrounding the base plate body 210; the side plates 100 are mounted on these base plate walls 220. Specifically, a pivot is provided between the base plate walls 220 and the side plates 100, allowing the side plates 100 to be rotatably mounted on the upper side of the base plate walls 220; after each side plate 100 is unlocked, it can rotate relative to the base plate walls 220.

[0029] The flap 300 is rotatably mounted on the side of the base plate 200 near the discharge hole 211 via a pivot (not shown). Additionally, refer to... Figures 4-6 The base plate 200 has top plate holes 212 corresponding to each flap 300, and the top plate holes 212 are located on the side of the base plate 200 away from the rotating shaft. Specifically, in this embodiment, the base plate 200 has 2N top plate holes 212, and each flap 300 has two top plate holes 212. During operation, multiple external push rods pass through the top plate holes 212 from bottom to top and continue to push upward, thereby lifting the free end of each flap 300 upward, which causes the multiple flaps 300 to converge and form a slope for guiding the material leakage hole 211. After the external push rods retract, they no longer support the flaps 300, and the flaps 300 no longer converge but fall back onto the base plate 200.

[0030] like Figures 1-3 As shown, a base frame 400 is provided on the lower side of the base plate 200 to support the base plate 200. The base frame 400 avoids the top plate hole 212 and the material leakage hole 211. The base frame 400 serves to support the base plate 200 and place it on external equipment. Specifically, in this embodiment, the base plate 200 is locked onto the base frame 400 by bolts and nuts.

[0031] Reference Figure 1 and Figure 2 The bottom plate 200 and the discharge hole 211 are connected by an arc-shaped transition. Regardless of the state of the flap 300, it helps guide the powder in the ton bag to the discharge hole 211.

[0032] Reference Figures 4-6 The inner bottom wall of the base plate 200 has multiple grooves 213 that connect to the material leakage holes 211. Each groove 213 corresponds to a flap 300. When the flap 300 is flat, it fills the groove 213 perfectly. In other words, the inner bottom wall of the base plate 200 has multiple protruding ridges 214, each extending from the inner side wall of the base plate 200 towards the material leakage hole 211, with adjacent ridges forming the aforementioned groove 213. When the flap 300 is flat, it is flush with the ridges 214, forming a plane, which allows for better placement of the ton bag. Furthermore, even if the ton bag is punctured, the powder inside will not remain on the inner bottom wall of the base plate 200 due to its unevenness.

[0033] like Figures 4-6 As shown, the outer contour of the inner bottom wall of the base plate 200 is also square. A groove 213 is provided between each side of the inner bottom wall of the base plate 200 and the material leakage hole 211; when the four flaps 300 are raised, they together form the gathering cavity a.

[0034] In one embodiment, such as Figures 4-5 As shown, the flap 300 is trapezoidal, with the side of the flap 300 closest to the material leakage hole 211 being the short side 310 and the side furthest from the material leakage hole 211 being the long side 320. The two inclined sides 330 connecting the short side 310 and the long side 320 are mirror-symmetrically arranged. Specifically, the angle between the long side 320 and the inclined side 330 is 45°. When the four flaps 300 are raised to the set angle, the inclined sides 330 of adjacent flaps 300 are completely joined, that is, the gathering cavity a formed by the four flaps 300 is tightly joined, which can prevent the powder in the gathering cavity a from falling into the protrusion 214 or the groove 213.

[0035] In one implementation, the flap 300 is rectangular, and the four flaps 300 can form a seamless gathering cavity a after being raised by 90°.

[0036] In some embodiments, other numbers of flaps 300 may be provided, and the shape of the flaps 300 is not limited. Preferably, after multiple flaps 300 are raised, a seamless gathering cavity a can be formed.

[0037] The working principle of this utility model is roughly as follows: By setting multiple flaps 300 on the base plate 200, the flaps 300 can be lifted away from the side of the leakage hole 211, so that the multiple flaps 300 are gathered together to form a slope that guides the leakage hole 211, which helps to fully and quickly release the powder in the ton bag; when the flaps 300 are in a flat position, there is more space in the accommodating cavity to accommodate the ton bag, so that the packaging box can be adapted to accommodate ton bags containing more powder. After part of the powder in the ton bag is released, the powder is further released by lifting the flaps 300 to form a slope.

[0038] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
