Problems solved by technology

Traditional tread rubber mainly includes butadiene rubber, natural rubber and styrene-butadiene rubber. Among them, BR has small rolling loss but poor wet grip; SBR has good wet grip but high rolling resistance; in between
To reduce the rolling loss of the tread without sacrificing wet grip, traditional single polymer materials are incapable

Embodiment Construction

[0011] The present invention will be further explained below.

[0012] A tread length measurement system suitable for tread loading, comprising a CCD / CMOS black-and-white camera, a graphics acquisition card, an image processing module, a size calculation module and a controller. Draw a grid and determine datum points on the surface of the conveyor belt connected to the tread compound extruder. The CCD / CMOS black and white camera faces the conveyor belt, and is fixed on the top of the conveyor belt by a bracket and away from the exit of the tread rubber extruder. Since the deformation of the tread from the tread rubber extruder has not been fully finalized, it is not suitable to measure the size at the exit of the tread rubber extruder, so this system is set far away from the exit of the tread rubber extruder Position, usually can be extruded in the tread rubber extruder outside the position of 5 treads.

[0013] The controller includes a photoelectric detection sensor. The p...

Abstract

The invention discloses a tread length measuring and calculating system suitable for tread loading. The tread length measuring and calculating system comprises a CCD / CMOS black-and-white camera, a graph acquisition card, an image processing module, a size calculation module and a controller. According to the system, the CCD / CMOS black-and-white camera is used for shooting the image of a tread on aconveyor belt connected with a tread rubber extruder, a black-white contour image of the tread is obtained by processing the shot image, corresponding calculation is performed by combining the grid size of the surface of the conveyor belt and the black-white contour size of the tread in the image, and then the accurate length size of the tread is obtained. The system utilizes a machine vision principle to realize accurate detection of the tread length, and has higher precision compared with detection and amplification through an angle encoder in the prior art.

Description

technical field [0001] The invention relates to a tread length measurement system suitable for tread loading. Background technique [0002] With the rapid development of the automobile industry and the transportation industry, road construction, especially the rapid development of expressways, various high-performance tires are urgently needed. Various new tires such as so-called safety tires, energy-saving tires, high-performance tires, winter tires, all-weather tires or all-season tires and environmental tires have occurred successively. After entering the 1990s, the widespread development of the green movement has enabled people to have a better understanding of fuel-saving benefits, and so-called "green tires" have appeared. In recent decades, research on tire performance at home and abroad has focused on rolling loss, wet skid resistance and wear resistance, especially wet skid resistance. These three performances are also called the three major driving performances o...
