Abstract

The invention discloses an RCA paper tape friction machine which comprises a machine base, a paper placing mechanism, a storage table, a conveying mechanism, a weight adjuster, a counter and a paper collecting mechanism. The weight adjuster comprises a cross rod, a sliding block capable of moving in the length direction of the cross rod, a push rod fixedly connected with the sliding block, and a locking mechanism used for fixing the position of the sliding block. The sliding block is arranged outside the cross rod in a sleeving mode, and a plurality of weight grooves are formed in the slidingblock. By arranging the weight adjuster, the load adjusting range is enlarged, so that more accurate load is set according to the specific hardness of a to-be-measured piece, and the accuracy of a measurement result is improved.

Description

Technical field [0001] The invention belongs to the technical field of testing equipment, and particularly relates to an RCA paper tape friction machine. Background technique [0002] RCA paper tape abrasion tester is suitable for testing the abrasion resistance of plastic surface coatings. It is mostly used for mobile phone key printing, mobile phone shells, MP3, CD players, laptop computers, PDAs, electrical appliances shells and other products. Due to the different soft and hard textures of the coatings of different parts under test, the load of the parts under test needs to be adjusted in the wear test to meet the friction requirements of different parts under test. [0003] The existing RCA paper tape abrasion tester will roughly classify the coating layer of the test piece when performing the load test, and divide the texture into three categories: hard, normal, and soft. If the texture is normal, the arm will be Hang a weight of 55g on the left lever. If the texture is soft...
