When in use, when the condensing plate comes out of the first process, it will be transferred to the turning and unloading machine. Roller drive mechanism 1 , the condensing plate is laid flat on the roller 18, The driving motor 1111 drives the reducer 1110 to rotate, thereby driving the roller drive gear 1114 at the end of the output shaft 1113 of the reducer to rotate. Due to the effect of the transmission chain 112, the driven roller gear 19, the roller 18 and the gear adjustment assembly 110 are driven to be synchronized. Rotate, the gear adjustment assembly 110 can automatically adjust the tension of the transmission chain 112 according to the motion state of the gear transmission, so that the gear transmission presents a compact and orderly rotation state, when the condensation plate was shipped to the Buffer protection device 34 corresponds to position, Roller Drive Cylinder 15 Adjust downwards to drive the entire upper frame 11 to translate downwards. At this time, the condensing plate will smoothly fall to the roller shaft interspersed in the transmission mechanism 1.
