The hot air blower 714 works, injecting hot air into the cavity 712 and spraying it from the nozzle 713 toward the surface of the thrown rubber, thereby performing secondary dehydration on the rubber. S3: three-stage dehydration; the two pressing rollers 802 are driven to rotate in opposite directions by the second motor 803 to dehydrate the rubber that has completed the second dehydration for the third time. At the same time, the cleaning roller 806 is driven to rotate synchronously to clean the rubber remaining on the surface of the pressing roller 802 and wipe off the water stains remaining on the surface of the pressing roller 802. The cleaning roller 806 drives the protrusion 807 to rotate synchronously, and with the cooperation of the spring 813, drives the connecting rod 808 to drive the blanking plate 805 to swing back and forth to prevent the rubber from accumulating on the surface of the blanking plate 805.
