After the motor 21 is turned on, the output end of the motor 21 drives the rotating roller 20 to rotate, and the rotating roller 20 drives the conveyor belt 22 to rotate, so that the carton on the surface of the conveyor belt 22 is transported to the bottom of the sealing machine 3, and the sealing frame 2 is fixedly connected to a fixed plate 11 on the side away from the supporting frame 4, and fixed The surface of the plate 11 is slidably connected with a slide bar 12, and the lower end of the slide bar 12 is fixedly connected with a pressure plate 13, a downward pressure spring 14 is arranged between the pressure plate 13 and the slide bar 12, and the downward pressure spring 14 is slidably connected to the surface of the slide bar 12, when the carton is sealed after passing through the pressure plate 13, the carton will push the pressure plate 13 to move upward, and the pressure plate 13 will push the slide bar 12 to move while moving upward, and will squeeze the downward pressure spring 14 upward, and the elastic deformation of the downward pressure spring 14 can flatten the tape at the sealing position, enhance the sealing effect, and avoid the problem that the tape is too loosely pasted and the box mouth is easy to crack during transportation.
[0020] Reference Figure 1 and Figure 2As shown, specifically, both sides of the processing table 1 are fixedly connected with a mounting plate 15, and an electric push rod 168 is installed on the surface of the mounting plate 15, and the output end of the electric push rod 168 passes through the surface of the mounting plate 15 and is fixedly connected to the limit frame 17.

The inner wall of the limit frame 17 is rotatably connected with a plurality of rotating cylinders 18, and the rotating cylinders 18 are evenly arranged and distributed. When the limit frame 17 limits the carton, the rotating cylinders 18 arranged on the inner wall of the limit frame 17 can reduce the friction between the side wall of the carton and the surface of the limit frame 17, so that the conveying of the carton is smoother.
[0021] Working principle: when it is necessary to seal the carton, first turn on the electric push rod 168, and the output end of the electric push rod 168 pushes the limit frame 17 to move, and by adjusting the distance between the two limit frames 17, the cartons of different widths are limited. Then, after turning on the motor 21, the output end of the motor 21 drives the rotating roller 20 to rotate, and the rotating roller 20 drives the conveyor belt 22 to rotate, so that the cartons on the surface of the conveyor belt 22 are transported to the sealing machine 3 for sealing. When the carton passes through the movable arm 5, the lower pressure wheel 6 at the lower end of the movable arm 5 will press the bent paper at the box mouth. The plate is pressed down to limit the position to prevent warping and ensure the effect after sealing. At the same time, the connecting plate 7 will push the push rod 8 to squeeze the limit spring 10 to prevent excessive squeezing of the limit wheel and damage to the surface of the carton. When the carton is sealed and passes through the pressure plate 13, the carton will push the pressure plate 13 to move upward. While the pressure plate 13 moves upward, it will push the slide bar 12 to move and squeeze the downward pressure spring 14 upward. The downward pressure spring 14 undergoes elastic deformation, which can flatten the tape at the sealing point to enhance the sealing effect and avoid the problem of the tape being too loosely pasted and the box mouth being easily cracked during transportation.
