Description
Technical Field
The invention relates to the technical field of tire retreading and new process tire production, in particular to an annular tread grinding machine.
Background
With the continuous development of the tire retreading industry, the technology of attaching the tire body to the tread is continuously being renovated. The traditional tyre retreading industry basically uses a strip-shaped tread to be attached to a waste tyre body to realize the retreading and recycling of the tyre. The advent of endless annular treads now further improves the control accuracy and fit tightness of retreaded tire tread fit pretension. However, before the annular tire tread is attached to the polished tire body, the attaching surface of the annular tire tread needs to be polished, and after the tire tread is polished to a certain roughness, the adhesive can be applied, and the process is completely to improve the adhesive force of the attaching surface of the tire tread after the adhesive is applied.
As the annular tire tread is in an emerging tire tread form, no related automatic annular tire tread polishing equipment is available in the market at present, and the whole annular tire tread polishing is in a manual or semi-automatic state.
Such as the annular tread dust removing and grinding machine disclosed in patent CN108942444A, which does not have a tread tension device, because the tread is a flexible body, the tread always keeps a loose state, and it is impossible to directly grind with grinding heads as described in the patent. In addition, the axis of rotation of the grinding heads described in patent CN108942444A is perpendicular to the central axis of the annular tread, so that in this case and enabling both grinding of the tread, there is only a small portion of grinding, and the tread must be turned and adjusted in position each time a portion is ground. In addition, in the grinding process of the device, the grinding head brings lateral force to the tire tread, the whole annular tire tread can shift towards the rotation direction of the grinding head in the grinding process, and finally the tire tread and the grinding head can be separated, so that the device does not have the practical grinding purpose of CN 108942444A.
Patent CN203543148U discloses a full-automatic equipment of polishing of annular prevulcanized tread for tire refabrication, this patent has practical use value than patent CN108942444A relatively, but this patent still has the shortcoming, for example, the wheel of polishing directly presses on the tread medial surface, there is not support piece to prevent the tread deformation in the point of polishing tread outside, because the tread produces vibration during the polishing, so the pressfitting power between wheel of polishing and tread changes constantly, lead to very easily that whole tread polishing in-process produces vibration and tread thickness is inhomogeneous in every place after polishing, the tread is thinner than the place thickness that polishing pressure is little in the place that polishing pressure is big. In addition, in the polishing state, the polishing wheel is almost in line contact with the contact point of the tire tread, and the polishing efficiency is low.
