Description

Technical Field

[0001] The utility model relates to the field of electromechanical control, in particular to a belt detection sample making machine. Background Art

[0002] At present, belt testing samples are cut manually with a sealing knife. Since a belt requires multiple models and specifications of testing samples, including roller friction test, tension, adhesion, resistance, flame retardant and other projects. The samples that need to be sampled are dozens of large, small, long and wide. They are all cut by two people, one person cuts, and the other helps to press the cut to open the inner layer one by one, which is time-consuming and laborious. Sometimes there is a risk of the sealing knife scratching the air during cutting, and the blade hurts people. The wrist of the person will be injured after working for a long time. The work efficiency is low.

[0003] When it is hot, the belt is softer and it is easier to prepare samples. When it is cold, it is harder and often more difficult to prepare samples. Since the samples cut manually are not very vertical and meet the standard specifications of the sample, they need to be clamped on the vise again for cutting. Samples are prepared using shearing equipment. Since the shearing equipment is hard extrusion for cutting, the belt is soft and elastic, the cutting surface is uneven or large or small, and the cut surface is not vertical. There are many nylon threads in the belt. Extrusion cutting will change the force point of the nylon thread. The two belts that are cut will bring out multiple nylon threads of each other, so the test data will be seriously biased. Samples are prepared using a cutting machine. The samples prepared by this method are relatively regular, and the disadvantages are also obvious. Since the cutting machine is a high-speed rotating device, the friction with the belt will generate high temperature and produce very thick smoke. First of all, the thick smoke will cause harm to the human body, and secondly, it will pollute the air. Utility Model Content
