Description

Technical Field

[0001] The invention relates to the technical field of steel plate coil processing, in particular to an automatic belt threading device for a slitting machine. Background Art

[0002] The slitting machine is an important machine in metal sheet processing equipment. The main function of the slitting machine is to cut wide metal coils, such as steel strips, aluminum strips, etc., longitudinally according to the set width to make them into narrow strips of coils or plates. It usually consists of an uncoiling part, a feeding part, a shearing part, a coiling part, etc.

[0003] The slitting machine does not clearly distinguish between oriented silicon steel and non-oriented silicon steel when shearing silicon steel. They are all collectively referred to as silicon steel shearing. Silicon steel has different thicknesses and is divided into two types of materials. Oriented silicon steel has high hardness, brittle material, and a magnesium oxide coating on the surface; non-oriented silicon steel is soft and easy to twist and deform. Due to the difference in physical properties, when threading the belt, it is necessary to follow its physical properties to avoid problems such as oriented silicon steel coating loss and non-oriented silicon steel bending.

[0004] In the prior art for shearing silicon steel, the uncoiled part of the metal coil is first unfolded, and then threaded by a manual machine, and the coil is transported to the shearing part.
