[0026] The present invention will be further described in detail below with reference to the accompanying drawings.
[0027] 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.
[0028] This embodiment relates to a packaging box with a material-stopping function. This packaging box with a material-stopping function changes the traditional disposable ton bag + pallet form, reduces transportation costs, increases storage capacity, and also improves the efficiency of material feeding.
[0029] like Figures 1-4 As shown, the packaging box with material-stopping function includes: a box body 100 and a closing device. The box body 100 is used to hold ton bags, and a material leakage hole a is opened at the bottom of the box body 100; the closing device is located on the inner bottom side or the outer bottom side of the box body 100, and is used to open or close the material leakage hole a.
[0030] A closing device located on the bottom side of the housing 100 allows the material leakage hole a to be opened or closed. Initially, the closing device closes the leakage hole a before the ton bag is placed inside. When material needs to be discharged, the closing device opens, exposing the leakage hole a. The bag-breaking head passes through the leakage hole a and punctures the ton bag. The user can close the leakage hole a at any time, effectively blocking the rupture and preventing further leakage of powder, thus controlling the discharge rate. The user can also adjust the size of the leakage hole a by sliding the cover plate 200, thereby adjusting the discharge speed.
[0031] In this embodiment, the bottom surface of the box 100 is square, and the material leakage hole a is circular and located in the center of the bottom of the box 100.
[0032] In this embodiment, as Figures 5-6 As shown, the closing device includes a cover plate 200 slidably mounted on the bottom outer side of the housing 100 for opening or closing the material discharge hole a. That is, the material discharge hole a is opened or closed by sliding the cover plate 200. More specifically, the cover plate 200 includes a first cover plate 210 slidably mounted on the bottom outer side of the housing 100, and a second cover plate 220 slidably mounted on the bottom outer side of the housing 100. The first cover plate 210 and the second cover plate 220 move towards or away from each other to close or open the material discharge hole a. Of course, the user can also partially close the material discharge hole a by sliding one of the cover plates 200, thus adjusting the material discharge speed.
[0033] As a preferred solution, such as Figures 4-6 As shown, the cover plate 200 has a downwardly protruding post 230 on the side away from the housing 100, which facilitates sliding the cover plate 200. The user can slide the cover plate 200 by operating the post 230, which is more convenient than sliding the cover plate 200 directly.
[0034] As a preferred solution, such as Figures 4-6 As shown, the closing device also includes a fixing plate 240 fixedly mounted on the bottom outer side of the housing 100. Specifically, in this embodiment, the fixing plate 240 is locked to the bottom outer side of the housing 100 by bolts and nuts. The cover plate 200 is located between the fixing plate 240 and the housing 100. The fixing plate 240 has a clearance hole b to avoid the leakage hole a, and a travel groove c for the protrusion 230 to slide back and forth. When the protrusion 230 slides along the travel groove c, it drives the cover plate 200 to slide back and forth to open or close the leakage hole a. The fixing plate 240 can effectively protect the cover plate 200; and the travel groove c on the fixing plate 240 can limit the sliding direction and travel of the protrusion 230, making the sliding of the cover plate 200 smoother.
[0035] More specifically, there is one fixed plate 240, the clearance hole b is located in the center of the fixed plate 240, and four travel grooves c are provided on the fixed plate 240. Each cover plate 200 corresponds to two travel grooves c, that is, each cover plate 200 is provided with two protrusions 230.
[0036] In some embodiments (not shown), the cover plate may include three or more small cover plates slidably mounted on the bottom side of the outer side of the housing, each of which can slide independently. In addition to opening or closing the entire discharge hole, the material discharge speed can be controlled by sliding different numbers of small cover plates.
[0037] In some embodiments (not shown), the closing device includes a third cover plate rotatably mounted on the bottom side of the outer side of the housing for opening or closing the leakage hole. Rotating the third cover plate is a viable alternative to a sliding method.
[0038] In some embodiments (not shown), the closing device includes a fourth cover plate detachably mounted on the bottom side of the outer side of the housing for opening or closing the leakage hole. Compared to sliding or rotating methods, a detachable mounting method for the fourth cover plate is also a feasible solution.
[0039] In all the above embodiments, a locking structure (not shown) can be provided on the closing device to ensure the stability of the closing device. After the leakage hole is fully opened, or not opened or closed, the locking device ensures that the closing device will not change position.
[0040] The working principle of this utility model is roughly as follows: A closing device located on the bottom side of the housing allows the leakage hole to be opened or closed. Initially, the closing device closes the leakage hole before the ton bag is placed inside. When material needs to be discharged, the closing device opens, exposing the leakage hole. The bag-breaking head passes through the leakage hole and punctures the ton bag. The user can close the leakage hole at any time using the closing device, effectively blocking the rupture and preventing further leakage of powder from the ton bag, thus controlling the discharge rate. The user can also adjust the size of the leakage hole by sliding the cover plate, thereby adjusting the discharge speed.
[0041] 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.
