When the cartons are being conveyed, the straightening components 1 on both sides of the conveyor belt limit and guide the cartons, and straighten the cartons on the conveyor belt 5, so as to avoid the skew of the cartons and ensure that the cartons can smoothly enter the carton sealing machine body 7 for sealing after being straightened, thereby effectively improving the sealing accuracy and quality of the cartons, and at the same time eliminating the operation of manually correcting the orientation of the cartons, saving manpower; when guiding cartons of different sizes, the servo motor 8 is started to work, and the servo motor 8 drives the distance adjustment component 2 to work, and the distance adjustment component 2 adjusts the space in the straightening component 1 that allows the cartons to pass, so that the straightening component 1 is suitable for guiding and straightening cartons of different sizes, effectively improving the scope of application of the device and improving the overall practicality of the device.

[0025] Further Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth specifically explaining that the distance adjustment component 2 includes two slide grooves 205 that are opened through the top surface of the top connecting plate 11 and arranged along the length direction of the top connecting plate 11. The top ends of the two vertical support plates 3 are rotatably connected with a double-rotation threaded rod 203. One end of the double-rotation threaded rod 203 is coaxially fixed to the output end of the servo motor 8. Both ends of the double-rotation threaded rod 203 are threadedly connected with nut sleeves 202. The outsides of the two nut sleeves 202 are fixed with outer sleeve blocks 201. The top ends of the two outer sleeve blocks 201 are fixed with guide columns 204 that are slidably adapted to the slide grooves 205. When guiding cartons of different sizes, the start The servo motor 8 is driven to work, and the output end of the servo motor 8 drives the double-rotation threaded rod 203 to rotate, and the rotating double-rotation threaded rod 203 drives the nut sleeve 202 and the outer sleeve block 201 to move, and the guide column 204 slides in the slide groove 205 to guide the movement of the outer sleeve block 201, so that the two outer sleeve blocks 201 move synchronously in opposite directions to each other, so that the two outer sleeve blocks 201 moving in opposite directions can adjust the space allowed for the paper box to pass through the alignment component, so that 1 can guide and align paper boxes of different sizes, effectively improving the application range of the device and improving the overall practicality of the device.

The guide plate 101 is fixed to the bottom of the outer block 201 by the connecting plate 103. When the outer block 201 is fixed, the two guide plates 101 are relatively fixed, so that the distance between the two guide plates 101 is constant. When the carton is in the process of conveying, the guide plates 101 on both sides of the conveyor belt 5 are used to limit and guide the carton. The multiple balls 102 are effectively reduced The friction resistance between the carton and the guide plate 101, the carton on the conveyor belt 5 is straightened, thereby avoiding the skew of the carton, ensuring that the carton can smoothly enter the carton sealing machine body 7 for sealing after being straightened. When guiding cartons of different sizes, the servo motor 8 is started to work, and the output end of the servo motor 8 drives the double-rotation threaded rod 203 to rotate, and the rotating double-rotation threaded rod 203 drives the nut sleeve 202 and the outer sleeve block 201 to move, and the guide column 204 slides in the slide groove 205 to guide the movement of the outer sleeve block 201, so that the two outer sleeve blocks 201 move synchronously in opposite directions, so that the two guide plates 101 are driven to approach or move away from each other synchronously by the two outer sleeve blocks 201 moving in opposite directions, so that the spacing between the two guide plates 101 can be conveniently adjusted, and the space allowed for the paper box to pass can be adjusted, so that the two guide plates 101 can guide and align paper boxes of different sizes.
