8. The production equipment of the mildew-proof preservative film according to claim 7, wherein the production equipment comprises the following components: a positioning sliding groove (602) is formed between two adjacent groups of positioning hole grooves (601), and the inside of the positioning sliding groove (602) is of a slope structure facing the rotation direction of the support shaft (6).

9. The production equipment of the mildew-proof preservative film according to claim 1, which is characterized in that: the material rod assembly comprises a winding rod (801), and rotating parts (8) are fixed at two ends of the winding rod (801); the feeding device comprises a material rack (902), a long slot capable of accommodating the rotating piece (8) is formed in the material rack (902), and a second pushing piece (903) is fixedly arranged at one end of the outer side of the material rack (902); the auxiliary device comprises a first pushing piece (9) fixedly connected with the external supporting structure, and an auxiliary rotating rod (901) is rotatably arranged on an expansion joint of the first pushing piece (9).

10. A production process of a mildew-proof preservative film, comprising the production equipment of the mildew-proof preservative film as claimed in claims 1-9, and is characterized in that: the winding flow is as follows

S1, placing a plurality of groups of rod assemblies in a feeding device, rotating a threaded pin (703) 703 to enable a positioning ball (702) 702 and a positioning hole groove (601) to achieve proper force required by separation, and controlling a first pushing piece (9) 9 to adjust an auxiliary rotating rod (901) 901;

S2, when the feeding device is used for the first time, a second pushing piece (903) 903 is started to enable a material rod to be pushed into one group of clamp assemblies, then the supporting shell (1) is manually rotated to enable the next group of clamp assemblies to face the output end of the feeding device, and the operation is repeated until all the clamp assemblies clamp the material rod device;

s3, referring to FIG. 2, wrapping the preservative film to be rolled on a group of material rod assemblies positioned on the right side of the transfer device, starting a driving motor (501), driving the driving motor (501) to drive a driving shaft (5) and a driving disc (4) 4 to rotate, driving the driving disc (4) 4 to drive a group of driving wheels (304) 304 on the driving assembly in a sliding bar (3), driving the driving wheels (304) 304 to drive another group of driving wheels (304) to drive through a driving part (305), and driving the driving wheels (304) 304 to abut against a rotating piece (8) 8 on the material rod assemblies to drive, so as to realize the rotating and rolling action of a rolling rod (801);

S4, referring to FIG. 2, when a group of material rod assemblies at the upper right corner is wound to a certain amount, the weight of the material rod assemblies and the preservative film is larger than the clamping force between the positioning balls (702) 702 and the positioning hole slots (601), at the moment, the positioning balls (702) 702 are separated from the positioning hole slots (601), the material rod assemblies with the preservative film wound at the upper right corner are originally rotated to the lower part, and due to the larger weight, the first elastic piece (306) 306 in the sliding bar (3) is powerless to pull the sliding bar (3), at the moment, the two groups of clamping pincers (202) 202 are opened at the upper top of the clamp assembly, and the material rod assemblies with the preservative film wound are separated;

S5, after the steps, the original upper left corner material rod assembly rotates to the upper right corner to be matched with the auxiliary rotating rod (901) to conduct rolling action, the auxiliary rotating rod (901) can assist rolling, the material rod assembly for rolling the preservative film can be supported, stress of the clamp assembly is reduced, and accordingly reciprocation is achieved, and continuous rolling of the preservative film is achieved.
