The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0029] The present utility model will be described in detail below in conjunction with the various implementations shown in the accompanying drawings:

[0030] As Figures 1-3 shown, in this embodiment, a bottom-closing box opening machine is provided, which includes a substrate 1, and also includes a storage mechanism, an adsorption and handling device, a forming component and a packaging component; an opening is provided in the middle of the substrate 1, and the provided opening is for the adsorption and handling device to pass through the substrate 1 to grab the paper box. An adsorption and handling device is fixedly provided below the substrate 1, the forming component is fixedly provided on the substrate 1, the forming component is arranged at the edge of the opening, the storage mechanism is erected above the forming component, and the packaging component is installed on one side of the forming component.

[0031] In this embodiment, the storage mechanism includes a storage rack 2 and a plurality of fixedly connected paper tray seats 3. The plurality of paper tray seats 3 are arranged in a ring on the storage rack 2. Each of the plurality of paper tray seats 3 is provided with a bottom tray extending towards the middle. Before forming, the paper box is in a sheet shape and is placed on the bottom tray; optionally, a jet head 4 is also fixedly provided on the substrate 1. The jet head 4 is used for discharging the formed paper box. After the paper box is formed and its bottom is packaged, the paper box is placed on the forming component. Subsequently, after the jet head 4 blows air, the paper box can be blown outwards to achieve the discharging effect.

[0032] In this embodiment, the forming assembly includes a fixed seat 7, an adjusting cylinder 5 and a pair of forming sheet metals 6. The fixed seat 7 is fixedly arranged on the substrate 1. One of the forming sheet metals 6 is fixedly arranged on the side wall of the fixed seat 7. The adjusting cylinder 5 is fixedly arranged on the substrate 1. The other forming sheet metal 6 is fixedly arranged on the piston rod of the adjusting cylinder 5. The fixed seat 7 and the adjusting cylinder 5 are respectively arranged on both sides of the opening, so that the two sheet metals can form a relative clamping force on the paper sheet, enabling the paper sheet to be quickly formed during the sinking process. The tops of the forming sheet metals 6 all bend and extend outwards. This bending design can make the paper sheet more smooth during the forming process. During the sinking process, the side box surface of the paper box will abut against the sheet metal and then be vertically formed.

[0033] The adsorption and handling device includes a fixed frame 8 and a lifting cylinder 9. The fixed frame 8 is arranged below the substrate 1. The lifting cylinder 9 is fixedly arranged on the fixed frame 8. A nozzle 10 is fixedly arranged on the piston rod of the lifting cylinder 9. The piston rod controls the nozzle 10 to continuously move in the vertical direction. When the piston rod moves upwards, it will pass through the opening and move below the storage mechanism, enabling the nozzle 10 to adsorb the paper sheet (paper box) at the bottom layer of the storage mechanism. The nozzle 10 is connected to an external air source for sucking the paper box placed on the storage component; the lifting cylinder 9 is located directly below the opening.

[0034] In this embodiment, it further includes a substrate 1. The encapsulation assembly is installed on the substrate 1. The encapsulation assembly includes an inner tongue bending top plate 20 and a plurality of encapsulation cylinders. The inner tongue bending top plate 20 is movably connected to the substrate 1 through the encapsulation cylinders. The inner tongue bending top plate 20 is used for initially bending the inner tongue 28, so as to make it easier to insert the lower box ear 27 into the upper box ear 25 during the folding and encapsulation process, and can improve the reliability after the bottom of the box is encapsulated.

[0035] In this embodiment, a lower box ear top block 21 is further arranged above the inner tongue bending top plate 20. The inner tongue bending top plate 20 is a flat plate arranged parallel to the substrate 1. The inner tongue bending top plate 20 can be translated through the control of the encapsulation cylinder to initially bend the end of the inner tongue 28. The substrate 1 is also fixedly provided with a middle adjustment seat 22. A middle encapsulation cylinder 23 is installed on the middle adjustment seat 22. The middle encapsulation cylinder 23 is adjustably and vertically movably connected to the substrate 1 through the middle adjustment seat 22. The lower box ear top block 21 is fixedly arranged at the end of the piston rod of the middle encapsulation cylinder 23. The lower box ear top block 21 is arranged above the inner tongue bending top plate 20 through the middle adjustment seat 22. The lower box ear top block 21 can move forward to encapsulate the lower box ear 27 inwards. The lower box ear top block 21 acts on the lower box ear 27, causing the inner tongue 28 integrally formed at one end of the top of the lower box ear 27 to be further inserted inwards, specifically inserting the inner tongue 28 into the inner wall of the upper box ear 25.

[0036] In this embodiment, a first encapsulation cylinder 16 extending obliquely upward is further installed at the bottom of the substrate 1. A packaging bending piece 17 is fixedly arranged on the piston rod of the first encapsulation cylinder 16, and the first encapsulation cylinder 16 controls the movement of the encapsulation elbow in the inclined direction. Since the first encapsulation cylinder 16 is arranged obliquely, the piston rod of the first encapsulation cylinder 16 moves obliquely. The packaging bending piece 17 is fixedly arranged at the top end of the piston rod, that is to say, the packaging bending piece 17 also moves obliquely. Therefore, when the packaging bending piece 17 moves obliquely upward, the lower box ear 27 can be initially turned upward to wait for the lower box ear top block 21 to move forward, and the inner tongue 28 at the end of the lower box ear 27 can be further inserted into the upper box ear 25.

[0037] In this embodiment, a pair of side encapsulation cylinders 18 are symmetrically arranged on both sides of the tongue bending top plate. A side box ear 26 top block 19 is fixedly arranged at the end of the piston rod of the side encapsulation cylinder 18. A pair of side encapsulation cylinders 18 are both equipped with side adjustment components, and the side encapsulation cylinder 18 is movably connected to the substrate 1 in an adjustable manner through the side adjustment components; the side encapsulation cylinders 18 are all arranged obliquely and can respectively bend the side box ears 26. Because in the box opening action, that is, when the side box surface is pulled up, the two side box ears 26 are pulled up vertically and perpendicular to the substrate 1. At this time, the movement of the side box ear 26 top block 19 will bend the two side box ears 26.

[0038] Further elaborating, the side adjustment component includes a relay board, a slide rail, a screw, an adjustment sleeve and a pair of bearing seats; the pair of bearing seats are fixedly arranged on the substrate 1. A slide rail is installed at the bottom of the relay board, and the relay board is movably connected to the substrate 1 through the slide rail; both ends of the screw are rotatably connected to the bearing seats, the adjustment sleeve is threadedly connected to the screw, the adjustment sleeve is fixedly connected to the relay board, and the side encapsulation cylinder 18 is fixedly arranged on the relay board.

[0039] A second encapsulation cylinder 24 extending obliquely downward is further fixedly arranged above the substrate. A second packaging bending piece is fixedly arranged at the end of the piston rod of the second encapsulation cylinder 24. The second encapsulation cylinder 24 is responsible for turning the upper box ear 25 downward. Therefore, the second encapsulation cylinder 24 controls the movement of the second packaging bending piece in the obliquely downward direction.

[0040] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as these combinations of technical features do not conflict, they should all be considered as the scope described in this specification. For those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
