[0025] Working principle: first, adjust the distance between the two second driven wheels 401 and the two driving wheels 403 according to the appearance size of the small box 3. When adjusting the distance between the two second driven wheels 401, reversely rotate the first T-shaped hold-down bolt to separate it from the corresponding moving rod, and release the fixation of the moving rod. At this time, the moving rod can be moved to move horizontally on the first T-shaped hold-down bolt through the corresponding first sliding hole. The moving rod drives the second driven wheel 401 to move its position through the corresponding pin shaft. After the distance between the two second driven wheels 401 is adjusted appropriately, stop moving the moving rod and rotate the first T-shaped hold-down bolt forward. The first T-shaped hold-down bolt is screwed into the corresponding first bolt groove and is in close contact with the top of the moving rod to fix the moving rod, thereby fixing the second driven wheel 401. Adjust the distance between the two driving wheels 403. When the second T-shaped pressing bolt 407 is rotated in the opposite direction to separate it from the corresponding moving plate 405, the fixing of the moving plate 405 is released. After the fixing is released, the moving plate 405 can be moved to slide vertically on the second T-shaped pressing bolt 407 through the corresponding second sliding hole 406, and the moving plate 405 drives the corresponding driving wheel 403 to move. After the positions of the two driving wheels 403 are adjusted, the second T-shaped pressing bolt 407 is rotated forward to fix the moving plate 405, thereby fixing the driving wheel 403, thereby completing the adjustment of the distance between the two second driven wheels 401 and the two driving wheels 403. The distance between the two second driven wheels 401 and the two driving wheels 403 can be adjusted according to the size of the small box 3, which can be suitable for small boxes 3 of different specifications, can meet the needs of multiple products on the same line, and improve the scope of application;

[0026] After adjustment, the operating speed of the driving component is set through the HMI touch screen 7 and the PLC controller 6 according to the speed of the automatic packaging line, and the speed of the clamping and flipping mechanism 4 is slightly greater than the speed of the automatic packaging line. The small box 3 is placed on the top of the conveyor belt 202, and the driving motor is started to drive the first driven wheel 201 on the right side to rotate through the first active wheel 203, the sprocket and the chain in turn. The first driven wheel 201 on the right side drives the first driven wheel 201 on the left side to rotate through the conveyor belt 202. The two first driven wheels 201 rotate at the same time to transmit the conveyor belt 202. The conveyor belt 202 in transmission transports the small box 3 to the right. When the box 3 enters the entrance of the second driven wheel 401 in the clamping and flipping mechanism 4, the circular clamping belt 402 clamps the small box 3 by friction, and as the running trajectory of the circular clamping belt 402 changes from vertical to horizontal, the small box 3 is flipped, and the flipped small box 3 enters the transmission mechanism 404, and the transmission mechanism 404 transports the small box 3 to the next process. Through the two vertically arranged second driven wheels 401, the two horizontally arranged driving wheels 403 and the setting of the limiting mechanism 5, the small box 3 can be quickly and accurately flipped, and there is almost no flipping failure. The flipping operation speed is fast and can be well matched with the automatic packaging line speed.
