Description

Technical Field

[0001] The utility model relates to the technical field of rubber testing, in particular to a multi-sample roller type abrasion machine. Background Technique

[0002] The abrasion resistance of rubber is an important performance index. The roller type abrasion machine is an instrument for testing the abrasion resistance of rubber. Its main principle is to cut and grind a cylindrical sample horizontally on the surface of the roller sandpaper under a certain load for a certain stroke, measure the mass abrasion of the sample, calculate the volume abrasion and the abrasion resistance index. At present, the more commonly used method for testing the abrasion resistance of vulcanized rubber is GB / T 9867 "Determination of Abrasion Resistance of Vulcanized Rubber or Thermoplastic Rubber (Rotating Roller Type Abrasion Machine Method)". Each rubber compound needs to make three samples, that is, three tests are required, and the working efficiency is relatively low. During the test, a large amount of rubber compound debris is generated by the friction between the sample and the surface of the sandpaper. Attaching to the surface of the sandpaper will affect its friction coefficient, and the experimental personnel need to constantly clean it, which is time-consuming and laborious. The rubber chips generated by the lateral movement of the sample on the surface of the sandpaper roller will splash with the rotation of the roller. Splashing onto the guide rod and lead screw at the rear of the equipment inside will cause blockage, and it is necessary to clean the rubber chips inside the equipment after stopping the machine.

[0003] In a patent with the patent publication number CN220455095U, a rubber roller abrasion machine with a protective structure is recorded. It reduces the pollution of the equipment to the environment through a protective cover, isolates the wear impurities from being discarded during the abrasion process, and ensures the operation of the equipment through the collection of the exhaust fan. This rubber roller abrasion machine with a protective structure performs abrasion on the abrasion disc and the fixed runner. During the abrasion process, the waste generated will splash along the surface of the fixed runner, and the waste will accumulate on the surface of the protective cover and the moving column, causing blockage, reducing the abrasion quality, and being inconvenient for the abrasion work.

[0004] Based on this, a multi-sample roller type abrasion machine is now provided, which can eliminate the drawbacks of the existing device. Content of the Utility Model
