Description

Technical Field

[0001] The invention relates to the technical field of cutting devices, and in particular to an automatic heat shrink tube cutting device based on a single chip microcomputer. Background Art

[0002] In electromechanical decoration and renovation projects, heat shrink tubing is widely used for insulating wires and cables, playing the role of moisture-proof, anti-corrosion and insulation. In the support and hanger brackets of pipelines and bridge frames, it is often used to prevent rust and corrosion of wire hangers. Usually, the cutting method of heat shrink tubing is manual measurement and then cutting, which is easy to cause measurement errors and uneven cuts. At present, the cost of finished heat shrink tubing cutting devices is relatively high and cannot be widely used. Conventional manpower uses a cutter to cut heat shrink tubing, which depends entirely on manual experience, so that the shape and size of the heat shrink tubing after cutting cannot be unified, and it is difficult to ensure the cutting effect of the heat shrink tubing. A large number of heat shrink tubing with uniform specifications and uniform lengths are required in electromechanical engineering. If all of them are cut manually, it will consume a lot of labor.
