Abstract:
A negative-pressure device for sanitary product production, comprising a box (1), a panel (2), and an air suction chamber (3) formed by the box (1) and the panel (2). The panel (2) is provided with an air hole (21), the middle of the air suction chamber (3) is provided with an air outlet chamber (5), and an air outlet of the air outlet chamber (5) acts on the direction of the panel (2). According to the negative-pressure device for sanitary product production, the air outlet chamber (5) is disposed in the air suction chamber (3), so that a negative-pressure box has both an air suction function and an air blowing function; moreover, when the negative-pressure box that can suction and blow air is used, and the negative-pressure box blows the air to an unqualified product, two qualified products adjacent to the unqualified product are suctioned by an air suction part of the negative-pressure box, so that the adjacent qualified products are not affected and interfered by air blowing, and a correct transport track therefor can still be ensured.
