The cutting rod 11 is slidably installed on the adjusting plate 704. The adjusting bracket 7 can change the height of the cutting rod 11. To change the height, first loosen all the nuts that fix the adjusting bolt 703 so that the adjusting bolt 703 can slide in the elongated hole 702 on the adjusting base 701. Then adjust the height of the adjusting plate 704 so that the cutting rod 11 can be aligned with the height of the edge sealing position. After adjustment, tighten the nuts again to fix the adjusting bolt 703 to complete the change of the height of the cutting rod 11, so that the cutting rod 11 can accurately align with the tape at the cutting position for cutting.

[0022] In this utility model, a baffle 16 is provided on the placement plate 3. The baffle 16 is fixedly installed on the placement plate 3. The baffle 16 located on the placement plate 3 can prevent the packaging box from falling off the placement plate 3 and thus affecting the sealing process.

[0023] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0024] In this implementation scheme: After placing the packaging box to be sealed on the placement plate 3, the electric telescopic cylinder 5 located on the liftable bracket 4 is activated. The baffle 16 located on the placement plate 3 can prevent the packaging box from falling off the placement plate 3 and affecting the sealing process. The liftable bracket 4 can change the height of the electric telescopic cylinder 5. When changing the height, the lifting bolt 405 is screwed on and removed from the positioning hole 402 and the adjustment hole 404. After removing the lifting bolt 405, the position of the connecting frame 403 on the lifting base 401 is adjusted. When the adjusted height meets the requirements, the lifting bolt 405 is screwed on again into the positioning hole 402 and the adjustment hole 404 to limit the connecting frame 403, thus completing the sealing of the electric telescopic cylinder 5. The height of the electric telescopic cylinder 5 can be adjusted to place larger packaging boxes on the placement plate 3 for sealing. The operation of the electric telescopic cylinder 5 drives the pressure plate 6 to contact the packaging box, confining it between the placement plate 3 and the pressure plate 6. Then, the end of the tape on the rotating plate 14 passes through the pulleys 13 on the two support rods 12 and is adhered to the sealing position of the packaging box. Next, the servo motor 1 located in the device base 2 is activated. The servo motor 1 drives the placement plate 3 to rotate, which in turn rotates the packaging box, causing the tape to wrap around the sealing position of the packaging box. The inner side of the pulley 13 is limited by the squeezing friction with the support rod 12, while the outer side can be rotated by the tape, and through squeezing friction... The pulley 13 and rotating plate 14 with friction limit can be adjusted in height on the support rod 12 so that the tape can be aligned with the required sealing height. After sealing is completed, the servo motor 1 stops running and the second motor 8 located on the adjusting bracket 7 is started. The second motor 8 drives the rotating plate 9 to rotate. The rotation of the rotating plate 9 drives the cutting rod 11 to slide on the adjusting bracket 7 via the transmission rod 10. The cutting rod 11 slides outward so that the serrated end cuts off the excess tape, completing the sealing work of the packaging box. The adjusting bracket 7 can change the height of the cutting rod 11. When changing, first loosen all the nuts of the fixing adjusting bolts 703 so that the adjusting bolts 703 can fit in the elongated hole 70 on the adjusting base 701. 2. Slide the inner plate 704 and adjust its height so that the cutting rod 11 can be aligned with the height of the edge sealing position. After adjustment, tighten the nut to fix the adjusting bolt 703 to complete the change of the height of the cutting rod 11, so that the cutting rod 11 can be accurately aligned with the tape at the cutting position for cutting. After the packaging box is sealed, the electric telescopic cylinder 5 and the second motor 8 are reset, and the sealed packaging box can be taken out from the placement plate. The servo motor 1, electric telescopic cylinder 5 and second motor 8 are centrally controlled by the control panel 15 located on the device base 2. There is no need to control them step by step, which improves the degree of automation and makes the operation of the staff simpler.
