The inner wall of the rotating frame 13 is rotatably provided with an extrusion wheel 14, and the sealing cover on the carton can be automatically closed by the extrusion wheel 14.

[0025] A plurality of electric telescopic rods 15 are fixedly connected to the opposite side of the two support plates 9, and the telescopic ends of the electric telescopic rods 15 are fixedly connected to the push plates 16. An infrared transmitter 17 is provided on the outer wall of one of the support plates 9, and an infrared receiver 18 corresponding to the infrared transmitter 17 is provided on the outer wall of the other support plate 9. The infrared transmitter 17, the infrared receiver 18 and the electric telescopic rod 15 are electrically connected to form a capping circuit.

[0026] The outer wall of the support plate 9 is fixedly connected to a connecting plate 19 , the outer wall of the connecting plate 19 is fixedly connected to a hydraulic telescopic rod 20 , and the telescopic end of the hydraulic telescopic rod 20 is fixedly connected to a push rod 21 .

[0027] A third motor 22 is fixedly connected to the inner wall of one side of the support frame 1, and the output end of the third motor 22 is fixedly connected to the first rotating rod 23. The inner wall of the other side of the support frame 1 is rotatably connected to the second rotating rod 24. The outer walls of the first rotating rod 23 and the second rotating rod 24 are transmission-connected with a belt 25.

[0029] The working principle of this utility model is as follows:

[0030] First, place the carton on the rotating rod 2 close to the push rod 21, then start the second motor 10, drive the rotating shaft 11 to rotate through the second motor 10, and then drive the other rotating shaft 11 to rotate through the gear pair, thereby driving the elastic telescopic rod 12 and the squeezing wheel 14 to close the carton cover on the carton, and then start the hydraulic push rod 21, and drive the push rod 21 to move forward slowly through the hydraulic telescopic rod 20, thereby pushing the carton to move synchronously. When the carton blocks the infrared light emitted by the infrared transmitter 17, the infrared receiver 18 will not be able to receive the infrared light. At this time, the infrared receiver 18 that cannot receive infrared light will transmit the electrical signal to the PLC controller, and the PLC controller controls the uppermost one that cannot receive infrared light. The electric telescopic rod 15 corresponding to the infrared receiver 18 is started, and then the push plate 16 is mobilized to close the remaining two carton covers. During this process, the first motor 7 and the third motor 22 are both started, and the threaded rod 8 is driven to rotate by the first motor 7, and then the packaging frame 4 moves downward until it contacts the top of the carton, and all the carton covers on the carton are squeezed and fixed by the extrusion bar 6. At the same time, the belt 25 is driven to rotate by the third motor 22. Since the clamping blocks on the belt 25 are respectively located at the upper and lower ends of the belt 25, the rotation of the belt 25 will cause the two clamping blocks to drive the conveying shell 28 to move toward the middle until the carton is clamped. The carton is conveyed forward through the conveying structure 29, and then sealed in combination with the tape packaging structure 5.
