[0019] Further, the top of the adjusting screw rod 7 is provided with a hexagonal nut which is fixedly connected with the adjusting screw rod 7.
[0020] The working principle of the utility model is as follows: the stacked packaging bags or packaging boxes are placed on the conveying belt 11, the distance between the two limiting baffles 9 is adjusted according to the width of the packaging bags, and the specific operation of adjustment is as follows: the screw rod 4 is rotated by a hand wheel, since the screw rod 4 is provided with a half right-hand thread and a half left-hand thread, when the screw rod 4 rotates, the two sliding blocks 5 on the two sides relatively translate, and the distance of movement is equal, so that the two sliding blocks 5 synchronously move, and the packaging bags are always kept in the middle position; after the width is adjusted, the height of the limiting part 81 is adjusted according to the thickness of the single packaging bag or packaging box, the adjusting screw rod 7 is twisted to drive the supporting plate and the sliding seat 8 to move up and down along the sliding rail, the distance of up and down movement is related to the number of rotations of the adjusting screw rod 7, so that when the pitch of the adjusting screw rod 7 is small, the height of the limiting part 81 can be accurately adjusted, the interval between the bottom end of the limiting part 81 and the conveying belt 11 is controlled to ensure that only one packaging bag or packaging box can pass through each time, and after adjustment, automatic code spraying work can be carried out; the pneumatic conveying mechanism 2 and the conveying belt 11, the conveying belt 11 drives the bottommost packaging box in the stacked packaging boxes to move to the conveying mechanism 2 through the gap of the limiting part 81 by friction force, since only one packaging box can pass through each time, the stacked packaging boxes are automatically separated and conveyed along the conveying mechanism 2, when the packaging box passes through the laser code spraying machine 1 in the conveying process, the laser code spraying machine 1 senses the passing packaging box and automatically sprays codes on the packaging box. In the whole code spraying process, manual intervention is not needed, and only the stacked packaging boxes need to be placed on the conveying belt 11.
