The invention discloses a roller press machine for a calcium silicate plate, and the roller press machine comprises a base, upper roller tubes, lower roller tubes, joint arm swing rod adjusting devices, a power device and steel belts. The upper roller tubes and the lower roller tubes are provided with multiple sets and are in one-to-one correspondence, the steel belts are arranged between the upper roller tubes and the lower roller tubes, the calcium silicate plate is squeezed to be molded by the upper roller tubes and the lower roller tubes on the steel belts, all the lower roller tubes are connected by a linkage mechanism I to realize linkage, any one lower roller tube is in linkage with the power device through a linkage mechanism II, the steel belts are driven to advance in the drivingdirection when the lower roller tubes rotate, the upper roller tubes are installed on the base through the joint arm swing rod adjusting devices, and the distance between the upper roller tubes and the lower roller tubes can be adjusted under the control of the joint arm swing rod adjusting devices. According to the roller press machine for the calcium silicate plate, the working principles of anordinary roller press machine and a conventional steel rolling machine are combined, and the roller press machine for the calcium silicate plate is simple and ingenious in structure, easy to assemble, convenient to maintain, low in fabricating cost and is suitable for the production of large calcium silicate plates.
