9. The preparation method of the polyvinyl chloride alloy and modified material preparation device is characterized by comprising the following steps:

step one, taking down a sealing cover (22), guiding required raw materials into a mixing barrel (2) through a feeding pipe (21), then resetting the sealing cover (22) and opening a heating mechanism and a first motor (33), wherein the heating mechanism heats the raw materials in the mixing barrel (2), meanwhile, the first motor (33) drives a wedge-shaped sleeve (35) and a main synchronizing wheel (310) to rotate through a driving rod (34), when a roller (37) moves from the bottom end to the top end of the inclined plane of the wedge-shaped sleeve (35) during the rotation of the wedge-shaped sleeve (35), one end of a rotating plate (36) far away from the mixing barrel (2) is driven to move upwards so as to drive a balancing weight (38) to move upwards, and then a connecting column (313) is driven to move downwards through a sliding block (314), the rotating rod (312) and a mixing blade (315) are further driven to move downwards, and when the roller (37) moves from the top end to the bottom end of the inclined plane of the wedge-shaped sleeve (35), the balancing weight (38) drives one end of the rotating plate (36) far away from the mixing barrel (2) to move downwards, so that the rotating rod (312) and the mixing blade (315) can be driven to move upwards through the connecting column (313), during the period, the main synchronizing wheel (310) drives the auxiliary synchronizing wheel (39) to rotate through the synchronous belt (311), so that the sleeve (32) is driven to rotate, the mixing blade (315) is driven to rotate through the rotating rod (312), raw materials are further mixed and stirred, and the raw materials are conveniently and fully mixed;

step two, after the raw materials are fully mixed at a high temperature, the first motor (33) can be closed, the electromagnetic valve is opened, so that the mixed raw materials are guided into the cooling box (4), then the second motor (54) and the fan (67) can be opened, at the moment, the second motor (54) drives the driving column (56) to rotate through the driving plate (55), so that the driving column rolls up and down along the inner wall of the driving ring (52), the driving ring (52) is driven to do circular reciprocating motion during the rolling of the driving column (56), so that the first rack (57) is driven to do circular reciprocating motion, the first gear (58) is driven to do circular reciprocating motion, the stirring piece (59) is further driven to do circular reciprocating motion through the cross rod (53), so that the high-temperature raw materials in the cooling box (4) can be stirred, and heat of the high-temperature raw materials can be radiated by the high-temperature raw materials;

and step three, the driving ring (52) is driven to do circular reciprocating motion through the side rod (61) while doing circular reciprocating motion, so that the screw rod (62) can be driven to do circular reciprocating rotation through the second gear (64), and then the moving block (65) can be driven to do circular reciprocating motion along the guide rod (68) by matching with the use of the guide rod (68), so that the fan (67) can be driven to do circular reciprocating motion through the clamping plate (66), and further the cooling of the raw materials can be accelerated, during the cooling period, the temperature of the raw materials needs to be synchronously monitored by workers, when the temperature of the raw materials is reduced to a proper temperature, the second motor (54) and the fan (67) are closed, and meanwhile, the raw materials are quickly led out of the cooling box (4) and are subjected to subsequent processing.
