A surface surplus woolen trimming device for tires according to claim 7, characterized in that the trimming table (51) is further provided therein with a turning assembly (6), the turning assembly (6) comprising: upset clamp splice (61) and fourth electric jar (62), two upset chambeies (63) have been seted up to pruning platform (51) upper surface symmetry, fourth electric jar (62) set up in upset chambeies (63) and fourth electric jar (62) output shaft vertical upwards set up, fourth electric jar (62) upper end is provided with second supporting shoe (64), upset clamp splice (61) set up two one side that second supporting shoe (64) are close to each other, and be connected through second telescopic link (65) between upset clamp splice (61) and second supporting shoe (64), be provided with on second supporting shoe (64) be used for driving second telescopic link (65) pivoted fifth motor (66).

9. A surface surplus woolen trimming device for tires according to claim 8, characterized in that the turning clamp block (61) is arranged in a cambered surface structure with the center shaft (31) as the center, and the vertical interface of the turning clamp block (61) is also arranged in a concave cambered surface structure.

10. A method of trimming excess surface burrs of a tire, suitable for use in a surface excess burr trimming device for a tire as claimed in any one of claims 1 to 9, comprising the steps of:

step one: conveying and trimming, namely placing the processed tire on a first conveyor belt (52), driving the tire to move forwards by the first conveyor belt (52), and pushing the tire forwards by a third electric cylinder (53) to push the tire to a trimming table (51) at the side part when the tire moves to the third electric cylinder (53);

step two: and after the tire is pushed onto the trimming table (51), the overturning clamping blocks (61) are clamped from two sides to the middle simultaneously, so that the tire is pushed to be right below the central shaft (31), at the moment, the mechanical arm drives the central shaft (31) to move downwards so that the central shaft (31) is inserted into the positioning holes (56) to complete positioning, and then the second telescopic rods (65) extend to enable the supporting blocks (12) to be in butt joint with the inner wall of the tire to complete supporting:

step three: the single-sided trimming is carried out, then the cutter head assembly (2) is started, the first motor (22) drives the circular cutter head (21) to rotate so as to trim the rough materials on the surface of the tire, and in the process, the second motor (42) drives the connecting sleeve (44) to rotate so as to adjust the angle of the circular cutter head (21), so that the circular cutter head (21) can finish trimming the upper surface, the side surface and the arc edge of the tire;

step four: turning over and trimming, then starting a fourth electric cylinder (62) to drive a second supporting block (64) and a turning-over clamping block (61) to ascend and stretch out, then clamping the tire by the turning-over clamping block (61) from two sides, then starting a fifth motor (66) to drive the turning-over clamping block (61) to rotate so as to finish turning over the tire and enable the bottom surface to turn upwards, and then continuing trimming by a cutterhead assembly (2);

step five: and (3) carrying out subsequent processing, wherein the mechanical arm controls the central shaft (31) to lift, and then the third electric cylinder (53) pushes out a long stroke to push the tire to the position of the second conveyor belt (55), and the second conveyor belt (55) drives the tire to move forwards continuously to finish the subsequent processing.
