After the control panel is used, the L-shaped rod is pulled in the opposite direction of the fixed plate. The movement of the L-shaped rod drives the moving rod to move. The movement of the moving rod drives the spring to stretch. When the L-shaped rod is away from the fixed plate, the dustproof plate is rotated and closed under the action of the rotating shaft. Under the action of the dustproof plate, dust and other impurities in the external environment can be prevented from falling onto the control panel, thereby preventing the surface of the control panel from being contaminated, making it convenient for subsequent operators to use the control panel.

The feed port 2 and the discharge port 3 opened by the barcode printer body 1 are flush with the upper surface of the transmission belt 7.

[0022] Embodiment 2: The difference between this embodiment and embodiment 1 is that four mounting brackets 11 are fixedly installed on the outside of the two supporting vertical plates 4, which are tightly connected to each other. At the same time, the other ends of the four mounting brackets 11 are fixedly connected to the support plates 12, which are tightly connected to each other. Slide grooves 13 are provided on both sides of the interior of the support plates 12, which facilitate the support and limiting of other components. At the same time, the top sides of the support plates 12 are fixedly connected to second support seats 14, which are tightly connected to each other. The upper surfaces of the two second support seats 14 are fixedly connected to the first electric push rods 15, which are fixedly supported by the second support seats 14. At the same time, the output ends of the two first electric push rods 15 are fixedly connected There is a linkage seat 16, which is driven by the first electric push rod 15.
