Novel tyre renovating sander

Abstract

The grinding machine for retreading tire includes one machine body, one grinding head and one feeding mechanism, and features its automatic control system comprising one data processing device and one set of detecting heads, and one servo control device to control the grinding head based on the command from the data processing device. The grinding machine of the present invention has the features of automation and high efficiency.

Description

technical field [0001] The invention relates to the technical field of tire retreading, in particular to a novel tire retreading grinding machine. Background technique [0002] With the continuous growth of my country's economy, road vehicles undertake a large number of freight transport tasks, and the continuous growth of vehicle ownership leads to a rapid increase in the use and consumption of automobile tires. The reuse of tire carcass can not only save a lot rubber and metal resources, and can avoid environmental pollution caused by tire exhaust, which has extremely huge economic and social benefits. [0003] At present, the main recycling method for the tire carcass is to achieve the purpose of recycling by grinding, repairing, and pasting pattern rubber, that is, tire retreading. [0004] In the existing tire retreading process, since the surface of the tire carcass is worn through use, a new layer of tread rubber needs to be pasted on the surface of the carcass, so th...

Problems solved by technology

[0007] One is to rely on simple manual visual inspection to manually control tire grinding. This grinding machine completely relies on the operator's judgment and manual inspection to control the grinding arc of the tire and the thickness of the remaining tire base after grinding, while the operator's own technology The level of performance will inevitably lead to uncertainty in the effect of tire grinding, which will greatly affect the effect of tire retreading;

[0008] The other is to make a profiling radian template in advance according to the model of the tire to be polished, and the die head will be polished according to the shape of the radian template during grinding. Although this method can better control the radian of grinding, but because each tire requires Prepare the corresponding template radian, and the template must be replaced frequently during grinding, which not only increases the operating strength, but also increases the cost of making the radian template, which is not economical and practical, and this kind of radian template cannot effectively control the remaining tires after grinding The thickness of the base, when the base rubber is polished too thick or too low will directly affect the quality of the retread tire, too thick will affect the heat dissipation performance of the tire and reduce the wear life, and too low will affect the quality of the tread bonding and cause quality problems such as tread falling off

[0009] The existing two types of grinding machines cannot effectively control the grinding temperature generated during tire grinding, and both types of grinding machines completely rely on the operator to judge the grinding temperature by visual inspection or feeling the smoke on the grinding surface

It is difficult to accurately judge the temperature of the grinding surface of the carcass by visual inspection or feeling. Because the blade of the grinding head of the grinding machine is continuously working and the amount of grinding feed is uneven, it often causes the temperature of the blade of the grinding head to be too high, and the grinding surface smokes, burns, and carbonizes. Phenomenon, too high surface temperature directly affects the bonding quality of new tread
