When customers purchase an uncoiler, Henli will not only ask about the basic properties of material width, material thickness, material, inner diameter and outer diameter, but also ask whether the surface of the material is covered with film and whether it is conductive.
This question needs to be asked because the standard uncoiler cannot uncoil non-conductive materials. At present, standard uncoilers basically use 12V DC induction voltage. In order to realize the automatic start and stop action of this induction method, the surface of the material must be conductive, so the non-conductive material cannot be uncoiled by the standard uncoiler.
Of course, it is also very simple to unwind non-conductive materials. The automatic unwinding of silicon steel sheets, non-conductive materials, surface-mounted film materials, and non-metallic materials can be realized simply by changing the sensing method of the uncoiler. There are three types of changes in the induction mode of the uncoiler, mainly three types: micro switch induction, proximity switch induction and photoelectric switch induction.
1. The uncoiler is replaced by the micro switch induction method, which is the most commonly used induction method for uncoiling non-conductive materials.
2. The uncoiler is replaced by the proximity switch induction method, which is used to unwind non-conductive metal materials (special attention: it cannot be used for non-metallic materials).
3. The uncoiler is replaced by the photoelectric switch induction method, which is used for uncoiling non-conductive metal materials and non-metal materials with high surface precision. There are two options: through-beam photoelectricity and diffused photoelectricity. The principle is that the material sags to a certain extent and stops the uncoiler after blocking the light of the photoelectric switch.
