The utility model provides a silk screen printing machine and a cleaning device for a silk screen mask. The cleaning device can reliably remove paste attached to the lower portion of the silk screen mask. A buffer part (50) with a convex body part with the center part as a top (50c) and a buffer part (51) with a convex body part with the center part as a top (51c) are installed in grooves in a nozzle (21). In the cleaning operation, the nozzle (21) which aligns with the lower portion of the silk screen mask (12) ascends, cleaning paper (23) is pushed to the lower portion of the silk screen mask (12), and meanwhile the silk screen mask (12) is lifted to the regulated height. At the moment, firstly, the top (50c) of the buffer part (50) and the top (51c) of the buffer part (51) abut against the center of the lower portion of the silk screen mask (12), then, the shapes of the protruding faces of the buffer part (50) and the buffer part (51) are simulated, the silk screen mask (12) is sequentially bent from the center of the lower portion to the two sides and meanwhile is lifted. In the state, the nozzle (21) is made to horizontally move in the cleaning direction. |
