Abstract

The embodiment of the invention provides an automatic sampling machine for separating and sampling multiple parts of a tire. The automatic sampling machine comprises a power distribution control box 1, a workbench 2, a sample placing table 3, a positioning and adjusting device 6 and a sampling and cutting device 7, wherein a contact type displacement sensor 13 is used for measuring the contour height of a cutting position on the upper surface of a to-be-sampled tire assembly 18; the power distribution control box is used for determining the cutting depth of the to-be-sampled tire assembly 18 according to the parameter mapping table after a user determines a tire part corresponding to the to-be-sampled tire assembly 18, and adjusting the target height of the sampling cutting device 7 in the Z-axis direction according to the measured contour height and the cutting depth, so that a cutting tool bit 71 is in contact with the upper surface of the to-be-sampled tire assembly 18, and a Z-axis driving hand wheel 8 is adjusted in real time in the cutting sampling process to change the target height so as to ensure that the cutting depth is not changed in the one-time cutting sampling process.

Description

technical field [0001] The present application relates to the technical field of tire testing, in particular, to an automatic sampling machine for separate sampling of multiple parts of tires. Background technique [0002] The European Tire and Rubber Manufacturers Association (ETRMA) conducted large-scale spot checks on tires in the EU market for two consecutive times. A total of 184 tests were conducted on 110 tires of 45 brands, among which PAHs in 21 parts of 12 tires were found to exceed the standard, with a failure rate of 10.9%. All substandard tires are produced in China. In order to meet the testing requirements of the EU standard ISO 21461, it is necessary to carry out cutting and sampling tests on each part of each layer structure of the tire according to the size and thickness required by the standard. The current common practice is manual sampling. Manual sampling is inefficient and prone to work-related accidents. Sampling is difficult due to the structure ...
