DETAILED DESCRIPTION

[0037] 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. Example

[0038] like Figure 7 As shown, the middle part of the formed paper box 31 is the main body of the paper box, and the two ends of the main body of the paper box are respectively provided with a first paper cover 311 and a second paper cover 312. The semi-finished paper box 31 is as follows. Figure 7 As shown, during the conveying process, the main body of the cardboard box is flattened. During the forming process, the main body of the cardboard box is first supported to form a cuboid structure. Then, the first paper cover 311 at both ends is rotated 90°, and the second paper cover 312 is pushed to rotate 90° to form the finished cardboard box.

[0039] like Figures 1-5 As shown, this embodiment discloses a fully automatic paper box forming machine, including a device body 1. The device body 1 is provided with a first conveying mechanism 2, a second conveying mechanism 3, a first gripping mechanism, a forming platform, a paper box forming component, and a second gripping mechanism. The semi-finished paper box 31 is placed on the forming platform through the first conveying mechanism 2 and the first gripping mechanism. The paper box forming component forms the semi-finished paper box and is conveyed and collected by the second gripping mechanism onto the second conveying mechanism 3.

[0040] like Figure 5 As shown, the tail of the first conveying mechanism 2 is also equipped with a paper blowing mechanism on both sides. The paper blowing mechanism initially blows open the semi-finished paper box. The paper blowing mechanism includes a first telescopic cylinder 4 and a paper blowing rod 5. The paper blowing rod 5 is a hollow structure. One end of the paper blowing rod 5 is connected to the output end of the first telescopic cylinder 4 through a connecting plate 6. The paper blowing rod 5 is connected to an air supply source, which provides air to the paper blowing rod 5. There are two of each of the first telescopic cylinder 4 and the paper blowing rod 5. After the first telescopic cylinder 4 drives the paper blowing rod 5 to be inserted into the semi-finished paper box 31 from both ends, the air supply source introduces air into the paper blowing rod 5, so that the semi-finished paper box 31 is opened from the inside to the outside, which facilitates the subsequent work.

[0041] like Figure 5As shown, the first grabbing mechanism comprises a coaxial reverse motor 7, a connecting rod 8, a first connecting frame 9, a first suction cup 10 and a forming auxiliary frame 11. The forward rotating wheel 12 of the coaxial reverse motor 7 is connected with one end of the connecting rod 8, and the other end of the connecting rod 8 is connected with the first connecting frame 9 through a bearing. The reverse rotating wheel 13 of the coaxial reverse motor 7 is connected with a first driven wheel 14 through a belt, and the first driven wheel 14 is rotationally connected with the first connecting frame 9. The first suction cup 10 is fixedly arranged on the first connecting frame 9 and is communicated with a gas source. The connecting rod 8 is driven to move by the forward rotating wheel 12, so as to drive the first connecting frame 9 to move as a whole, and the first connecting frame 9 is moved to the forming platform. In this process, the reverse rotating wheel 13 drives the first connecting frame 9 to rotate along the axis of the first connecting frame 9 through the first driven wheel 14, so that the first suction cup 10 is rotated from the horizontal orientation to the vertical orientation. When the first suction cup 10 is moved to the forming platform, the semi-finished carton 31 is placed in the forming platform.

[0042] The forming auxiliary frame 11 is fixedly arranged at the front end of the first conveying mechanism 2. The forming auxiliary frame 11 is composed of two opposite downwardly curved auxiliary rods and a fixed rod connected between the other ends of the auxiliary rods. The auxiliary rods of the forming auxiliary frame 11 are arc-shaped. When the first suction cup 10 drives the semi-finished carton 31 to move, one corner of the semi-finished carton 31 is in frictional contact with the auxiliary rods of the forming auxiliary frame 11, so that the cross section of the semi-finished carton 31 is gradually expanded from a rhombus to a rectangle.

[0043] As shown in Figure 5 , the forming platform is U-shaped and comprises a mounting base 15 and limiting pieces 16 located on both sides of the mounting base. The two limiting pieces 16 and the mounting base 15 cooperatively form a cuboid placing platform. The length of the carton body is consistent with the length of the forming platform. When the semi-finished carton 31 is placed in the forming platform, the first paper cover 311 and the second paper cover 312 at both ends of the semi-finished carton 31 can be exposed from both ends of the forming platform, which facilitates the next forming step.

[0044] As shown in Figure 5 and Figure 6As shown, the carton forming assembly comprises glue dispensing needles 17, a second telescopic cylinder, a third telescopic cylinder and forming rollers 18, two of the glue dispensing needles 17 and the forming rollers 18 are arranged at two ends of the carton body respectively. The second telescopic cylinder is arranged below the first conveying mechanism 2, the output end of the second telescopic cylinder is connected with the glue dispensing needles 17 through a first mounting plate 19, the glue inlet of the glue dispensing needles 17 is connected with the hot melt glue machine through the first mounting plate 19, when the second telescopic cylinder drives the glue dispensing needles 17 to move forward through the first mounting plate 19, the hot melt glue machine synchronously supplies glue to the glue dispensing needles 17, so that the glue dispensing needles 17 apply glue on the surface of the first cover 311. The third telescopic cylinder is arranged below the second conveying mechanism 3, a second mounting plate 21 is fixedly arranged on the output end of the third telescopic cylinder, two forming rollers 18 are arranged at two ends of the second mounting plate 21 respectively and are located outside the two glue dispensing needles 17. After the glue dispensing needles 17 extend and apply glue on the first cover 311, the forming rollers 18 extend and push the second cover 322 to cover the surface of the first cover 311, and the carton is formed through the glue bonding.

[0045] The forming rollers 18 are connected with the second mounting plate 21 through a connecting plate 20, and a torsion spring 23 is arranged between the connecting plate 20 and the second mounting plate 21. Since the original direction of the second cover 322 is consistent with the extension direction of the carton body, during the extension of the forming rollers 18, the second cover 322 needs to be rotated by 90° (since it needs to cover the surface of the first cover 311, at this time, the resilience of the first cover 311 and the second cover 322 needs to be overcome, which is greater than the resilience that needs to be overcome when the glue dispensing needles 17 apply glue on the first cover 311), in order to ensure the forming effect of the carton, the torsion spring 23 is arranged to ensure that the forming rollers 18 cannot move along the original direction of the second cover 322, so as to ensure that the second cover 322 is rotated by 90°, and the forming effect and the quality of the finished product are improved.

[0046] As Figure 5As shown, the second grabbing mechanism comprises a rotating motor 24, a second connecting frame 29, a driving wheel 25, a second driven wheel 26, a third connecting frame 27, a fourth connecting frame 28 and a second suction cup 30, the rotating motor 24 is arranged beside the second conveying mechanism, a driving wheel 25 is arranged on the rotating shaft of the rotating motor 24, the driving wheel 25 is connected with the second driven wheel 26 through a belt, two third connecting frames 27 are arranged in parallel, one end of the two third connecting frames 27 is connected with the driving wheel 25 and the second driven wheel 26 respectively, the other end of the two third connecting frames 27 is connected with the fourth connecting frame 28, the second connecting frame 29 is vertically fixedly arranged at the middle part of the fourth connecting frame 28, and the second suction cup 30 is fixedly arranged on the second connecting frame 29.

[0047] In the embodiment, the first conveying mechanism 2 is provided with a first photoelectric sensor at the tail end for monitoring the consumption of the semi-finished cartons, and the device stops working when no semi-finished carton is detected behind; and the second conveying mechanism 3 is provided with a second photoelectric sensor at the front end for monitoring whether the second grabbing mechanism delivers the finished carton to the second conveying mechanism 3, and the device stops working when no finished carton is detected.

[0048] In use, the semi-finished carton 31 is gradually moved under the transportation of the first conveying mechanism 2, is preliminarily supported by the paper blowing mechanism, is placed in the forming platform by the first grabbing mechanism, is completely supported into a cuboid shape under the limiting of the forming platform, and is folded and closed at both sides by the carton forming assembly, so that the forming of the carton is completed, and the second grabbing mechanism is used for grabbing the carton to the second conveying mechanism 3 for transportation and collection.
