DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

The carton is placed on the packing table 1, and the driving end of the oil cylinder 32 is retracted to drive the connecting frame 5 to move inward, so that the conveying roller three 7 contacts the outer wall of the carton. The carton is transported forward by the rotation of the conveying roller three 7. At the same time, the connecting frame 5 can push the carton to move inward during the process of moving inward, which has the effect of centering the carton. After the carton is transported into the return frame 11, the rotation of the conveying roller three 7 is stopped, and the telescopic rod is started to drive the connecting rod 10 and the return frame 11 to move upward. The return frame 11 moves upward along the outer wall of the carton, pushing the flap of the carton to stand up, and the airflow derived from the air outlet 34 on the return frame 11 pushes the flap of the carton to rotate inward, which is convenient for the subsequent pressing plate 12 to squeeze the flap to a horizontal level when it contacts the flap.

[0019] Furthermore, the multiple air outlets 34 located on the front and rear side walls of the return frame 11 and the multiple air outlets 34 on the left and right side walls are connected by U-shaped tubes. The two U-shaped tubes are respectively connected to air compressor 1 35 and air compressor 2 36 through air pipes. When flipping the carton, first start air compressor 1 35 to make the front and rear flaps rotate inward under the action of airflow, and then start air compressor 2 36 to make the left and right flaps rotate inward under the action of airflow, thereby realizing the preliminary folding of the flaps. Air compressor 1 35 and air compressor 2 36 are fixed in the packaging table 1.

[0020] A hydraulic cylinder is fixedly embedded in the upper side wall of one of the connecting frames 5, and a pressing plate 12 is fixedly connected to the driving end of the hydraulic cylinder. A steam mechanism is provided on the pressing plate 12. After the flap is initially folded, the hydraulic cylinder is started to drive the pressing plate 12 to move downward, so that the pressing plate 12 squeezes the flap and shapes the flap.

[0021] The steam mechanism includes a water tank 13 fixed on the upper side wall of the pressing plate 12 and an electric heating network 23 located in the pressing plate 12, a partition 20 is provided in the water tank 13, a dripper 21 is connected to the lower side wall of the partition 20, the lower end of the dripper 21 extends to the inside of the electric heating network 23, a motor 22 is fixed in the pressing plate 12, the driving end of the motor 22 is fixedly connected to an umbrella-shaped block 24 located in the electric heating network 23, the end of the dripper 21 is located on the upper side of the umbrella-shaped block 24, an air outlet pipe 27 is provided in the pressing plate 12, one end of the air outlet pipe 27 is connected to an air pump 26, a sealing rod 28 is slidably inserted at the other end of the air outlet pipe 27, an air inlet groove is provided at the right end of the sealing rod 28, a steam port 25 is provided on the lower side wall of the pressing plate 12, an air inlet connected to the inside of the pressing plate 12 is provided on the inner wall of the steam port 25, and the sealing rod 28 is provided on the inner wall of the steam port 25. An exhaust port is provided on the outer wall, and the end of the blocking rod 28 is fixedly connected to the limiting rod 29. The end of the limiting rod 29 is slidably inserted on the dripper 21. When the limiting rod 29 moves sideways toward the dripper 21, the water in the dripper 21 drops onto the umbrella block 24, and the motor 22 drives the umbrella block 24 to rotate. The water droplets on the umbrella block 24 are thrown outward, so that the water droplets contact and collide with the electric heating net 23 to disperse the water droplets. At the same time, the electric heating net 23 heats the dispersed water droplets to generate high-temperature water vapor. When the exhaust port is connected to the inside of the pressing plate 12, the airflow drives the high-temperature water vapor to be discharged from the air inlet to the steam port 25, and contacts the flip cover. The shaping effect of the high-temperature water vapor makes the horizontal state of the flip cover quickly fixed, ensuring that the flip cover will not rotate when the carton continues to move forward.

[0022] A moving mechanism connected to the blocking rod 28 is provided in the pressing plate 12, and the moving mechanism includes a motor fixed in the pressing plate 12, and the driving end of the motor is fixedly connected to an incomplete gear 1 30, and an incomplete gear 2 31 is installed in the pressing plate 12. The ends of the incomplete gear 1 30 and the incomplete gear 2 31 are fixedly connected to pulleys, and a belt is commonly sleeved on the two pulleys. The outer wall of the blocking rod 28 is provided with saw teeth, and the incomplete gear 1 30 and the incomplete gear 2 31 are intermittently meshed with the saw teeth. When the incomplete gear 1 30 is meshed with the saw teeth, it drives the blocking rod 28 and the limit rod 29 to move to the left, and the limit rod 29 closes the dripper 21 and stops. Stop water from flowing out. At this time, the exhaust port on the blocking rod 28 is connected to the pressure plate 12, and the air flow discharged by the air pump 26 is discharged into the pressure plate 12 through the exhaust port, pushing the high-temperature water vapor in the pressure plate 12 to be discharged into the steam port 25. When the incomplete gear 2 31 rotates to engage with the sawtooth, it drives the blocking rod 28 to move to the right. At this time, the exhaust port contacts the inner wall of the air outlet pipe 27 to be closed, and the limit rod 29 moves to the right to open the dripper 21. The dripper 21 contacts the water droplets and the umbrella block 24. The setting of the moving mechanism ensures that the exhaust port will discharge the air flow to blow out the high-temperature water vapor only when the water droplets are fully dispersed and heated to form high-temperature water vapor.

[0023] The packaging mechanism includes a belt roller 14 installed on the upper side of the connecting frame 5, and a tape 8 is wound on the belt roller 14. A groove is opened on the inner wall of the connecting frame 5, and an electric trolley 17 moves in the groove. The electric trolley 17 is provided with an air pump and a suction cup, and the suction cup is fixed on the outer wall of the electric trolley 17. The input end of the air pump is connected to the end of the suction cup. Two motors are fixed on the inner top wall of the connecting frame 5. The driving ends of the two motors are respectively fixed with a pressure roller 15 and a pressure roller 2 16. The tape 8 passes through Pressing roller 15 and pressing roller 2 16 are arranged. After the flap is pressed to the horizontal level, conveying roller 3 7 and conveying roller 2 4 drive the carton to continue to move forward. The vacuum pump works to extract the gas in the suction cup, and negative pressure is generated at the end of the suction cup to adsorb the end of the tape 8. When the middle part of the carton moves into the packing frame 33, the rotation of conveying roller 1 3 and conveying roller 2 4 is stopped, and the electric trolley 17 is started. The electric trolley 17 moves along the outside of the carton, so that the tape 8 is wound around the outer wall of the carton to complete the packing work.

[0024] Furthermore, release paper is fixedly sleeved on the outer walls of the pressure roller 15 , the pressure roller 2 16 and the electric trolley 17 , and the release paper prevents the adhesive tape 8 from adhering to the pressure roller 15 , the pressure roller 2 16 and the electric trolley 17 .

[0025] A fixing plate 19 is fixed on the outer wall of the connecting frame 5, and a cylinder 18 is fixedly embedded on the fixing plate 19. A cutter is fixed to the driving end of the cylinder 18. An opening corresponding to the position of the cutter and connected to the groove is opened on the outer wall of the connecting frame 5. After packaging is completed, the cutter contacts the tape 8 when the driving end of the cylinder 18 is extended to cut the tape 8. The electric trolley 17 then moves to the initial position to adsorb the tape 8.

[0026] Furthermore, in the process of the electric trolley 17 driving the tape 8 to be wound, the motor can drive the pressure roller 15 to reverse and drive the pressure roller 2 16 to rotate forward, so that the end of the tape 8 is pulled upward and the tape 8 is tightened, ensuring that the tape 8 can fit the carton.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
