Through starting the second motor, it rotates to drive the second motor shaft, thereby it stirs the cooling once more to drive second stirring vane to the material, simultaneously the second motor shaft drives first bevel gear and rotates, first bevel gear rotates and drives the third bevel gear rotation of meshing with it, third bevel gear drives the second bevel gear rotation of meshing with it, thereby it rotates to drive the second axis of rotation, the second axis of rotation drives the head rod and rotates, thereby it rotates to drive the scraper blade on the second connecting rod, through the setting of telescopic link and first expanding spring, make the scraper blade can be fine when the pivoted hug closely the inner wall of cooling chamber, make the material attached to on the inner wall of cooling chamber clear away, also can guarantee the cleanness and the stability of device when avoiding the material extravagant.

The first straight gear is driven to rotate through the rotation of the second rotating shaft, so that the second straight gear meshed with the second rotating shaft is driven to rotate, the second straight gear drives the fan blades on the third rotating shaft to rotate, the air circulation inside the cooling chamber is increased, and the cooling efficiency is further improved.

The fan is used for radiating heat of the second motor, the material cooling efficiency is improved, the third handle is pulled to separate the second sliding rod from the second clamping groove, simultaneously, the second handle is pulled to enable the first sliding rod to be separated from the first clamping groove, the bottom end of the second sliding rod can slide in the bottom end of the sixth through hole while the first sliding rod is pulled until the bottom end reaches the upper part of the other second clamping groove, the second sliding rod is clamped in the second clamping groove through the matching of the sliding block and the second telescopic spring, at the moment, the fixation of the fan is released, after the fan is adjusted to a required angle by rotating the first handle, the third handle is pulled and the second handle is pushed to enter the other first clamping groove at the same time, then the second sliding rod is placed into the second clamping groove to be fixed, fix the fan to the completion is to the regulation of fan angle, realizes improving cooling efficiency to the diversified heat dissipation of second motor.
