Specific Embodiments

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

[0022] Embodiment 1

[0023] The present utility model provides a case opening and bottom sealing machine, which includes a vertical stand 1. A three-axis module 2 is arranged on the stand 1. The three-axis module 2 includes an X-axis module, a Y-axis module and a Z-axis module, which is a common structure in the prior art and will not be repeated herein. And the figure shows a simplified view. The three-axis module 2 is installed on the stand 1. A suction device 3 is connected to the vertical module of the three-axis module 2. The suction device 3 is used to grasp the carton 16;

[0024] Among them, the suction device 3 includes a suction plate 10. A plurality of suction cups 11 are arranged at the lower part of the suction plate 10. A side plate 12 is movably connected to the side of the suction plate 10. Suction cups 11 are arranged on the side plate 12. A connecting shaft 13 is arranged on the side of the suction plate 10. The side plate 12 is sleeved on the connecting shaft 13. A connecting plate 14 is fixedly connected to the side plate 12. A cylinder 15 is connected to the suction plate 10. The output end of the cylinder 15 is rotatably connected to the connecting plate 14. An annular mechanism is arranged at the output end of the cylinder 15 and is connected to the connecting plate 14. When the cylinder 15 extends, the connecting rod presses the side plate 12 to rotate along the connecting shaft 13 until the suction cups 11 on the side plate 12 adsorb the side wall of the box body. Adjusting the cylinder 15 can adjust the shape of the box body.

[0025] The stand 1 includes a frame-shaped mechanism. A fixing rod 4 is arranged in the middle of the frame structure. A first folding mechanism 5 and a second folding mechanism are successively arranged on the fixing rod 4. Among them, the first folding mechanism 5 includes a group of V-shaped retaining pieces 8. The V-shaped opening of the retaining piece 8 points to the box body grasped by the three-axis. The opening of the box body also faces the retaining piece 8. The retaining piece 8 is connected to the fixing rod 4 through a rotating pin. The end of the retaining piece 8 is connected to the fixing rod 4 through an elastic member 9. The elastic member 9 can be a spring. The spring can increase the floating of the retaining piece 8 and prevent excessive pressing of the carton 16. The first folding mechanism 5 is arranged below the three-axis module 2. After the three-axis module 2 sucks the carton 16, the carton 16 can be opened to form a three-dimensional structure. Two horizontally opposite cover plates 17 of the box body are pressed towards the retaining piece 8 by the three-axis module 2. Due to the V-shaped arrangement of the retaining piece 8, the cover plates 17 of the box body are pressed and folded to close the box body.

[0026] After the horizontal cover plate 17 is hemmed, the vertically opposite cover plates 17 need to be hemmed. In this embodiment, a second hemming mechanism is particularly provided, that is, a hemming rod 6 arranged parallel to the fixed rod 4. The three-axis module 2 grabs the box body and extends its upper and lower groups of edges between the hemming rod 6 and the fixed rod 4. By horizontally and vertically moving the three-axis module 2 at the same time, the hemming rod 6 presses the cover plate 17 to be folded into shape. When the three-axis module 2 continues to move horizontally to the end of the fixed rod 4, a sealing glue core 7 is provided on the fixed rod 4. The sealing glue core 7 is an existing component, and reference can be made to the structure of the sealing machine core and the sealing machine disclosed in CN 205293261 U. It will not be repeated in this embodiment.

[0027] The suction device 3 grabs the box body and extends it between the hemming rod 6 and the fixed rod 4 to move up and down. After hemming the flip cover of the box body, it will move towards the sealing glue core 7, and the sealing glue core 7 will attach the tape to the opening of the box body and seal the box body.

[0028] In this embodiment, an unpacking and bottom-sealing method is also proposed.

[0029] S1: Place the side walls of the folded cardboard box 16 flat on the ground, with the openings of the cardboard box 16 pointing to the vertical frame 1 respectively. In this solution, all the box bodies are placed horizontally. When sucking up the box body, the box body can be pre-opened by itself, which is more convenient for the suction cup 11 on the side plate 12 to adsorb and open the box body.

[0030] S2: The suction device 3 of the unpacking and bottom-sealing machine as described in any one of the above adsorbs the side wall of the cardboard box 16. When the suction device rises upward, the cardboard box 16 is initially opened, and the adjacent side walls of the cardboard box 16 are adsorbed and fully opened by folding the side plate 12 of the suction device 3.

[0031] S3: Transport it to the first hemming mechanism 5 through the three-axis module 2, fold the two sets of opposite horizontal cover plates 17 (cover plates 17) of the cardboard box 16, and then transport the cardboard box 16 through the three-axis module 2 so that the other set of vertical cover plates 17 extend between the hemming rod 6 and the fixed rod 4. After the three-axis module 2 moves up and down, the vertical cover plates 17 are hemmed.

[0032] S4: Transport it to the sealing machine core through the three-axis module 2, and seal the cardboard box 16 with tape through the sealing machine core, that is, the entire box body is sealed with glue. This device cooperates with the horizontal placement of the box body through the three-axis module 2, reduces the complexity of the structure, will not have the problem of box jamming, and greatly reduces the equipment cost.
