AI Technical Summary

Technical Problem

Existing tire inner liner production line defect detection suffers from problems such as large workload and inaccuracy in manual identification, and inaccurate defect location due to different shrinkage ratios of inner liners of different specifications.

Method used

A detector is used to detect defects in the inner lining layer, and the defect locations are marked from the side and top surfaces respectively by first and second markers. The position of the markers is adjusted by an adjustment mechanism to ensure that the marks remain aligned with the defects after the inner lining layer shrinks. The marking is done using an inkjet printer, and the defect locations are recorded by a take-up and metering mechanism.

Benefits of technology

This technology enables accurate location of defects even after the inner lining layer has curled, preventing missed defects and ensuring that defect-free inner lining layers can proceed to the next process, thus improving the accuracy and efficiency of defect detection.

Abstract

The application discloses a defect positioning device for a tire inner liner production line, and belongs to the technical field of tire production, which comprises an inner liner production line and a detection mechanism, the inner liner production line is used for producing an inner liner, the detection mechanism is provided with a detector, and the detector is used for detecting defects of the inner liner, characterized in that the device further comprises a marking mechanism, the marking mechanism comprises a first marker, the first marker is opposite to an outer side of the inner liner, and the first marker is used for marking a side of the defect; after the inner liner is shrunk, the marked position is also correspondingly shrunk; after the inner liner is curled into a roll, the marking can be guaranteed to be opposite to the position of the defect, and the accuracy of defect positioning is guaranteed; when the defect is cut, the position of the defect can be seen from the side, the defect can be avoided from being missed, and then the inner liner with the defect can be avoided from flowing to a next process.
