[CN 201711243845.3] A Steel Strap Shearing Machine and a Shearing Control Method for Preventing Loose Roll Slippage Title: A Steel Strap Shearing Machine and a Shearing Control Method for Preventing Loose Roll Slippage Application Number: CN 201711243845.3 Applicant: Shanghai Meishan Iron and Steel Co., Ltd. Application Date: 2017-11-30 Patent Type: Application for the Invention The present invention relates to a Steel Strap Shearing Machine and a Shearing Control Method for Preventing Loose Roll Slippage. The steel strap shearing machine of the present invention includes a base and a shearing mechanism, a strap storage mechanism and a control cabinet sequentially installed on the base. The strap storage mechanism includes a bottom plate, and the top of the bottom plate is close to the shearing mechanism. A guide groove is provided on one side, and a T-shaped partition is vertically installed on the horizontal center line of the upper end surface of the bottom plate, and the middle part of the T-shaped partition is a semicircular notch, A semi-circular plate-type permanent magnet is nested on the notch, a symmetrically installed magnetic roller is arranged at the lower part of the T-shaped partition, and a pneumatic brake is correspondingly arranged on each magnetic roller. At the same time, an encoder for detecting the rotation speed of the roller is installed on the output shaft side of the magnetic roller. The invention solves the technical problem that the cutting length is not accurate and the blade gap cannot be adjusted quickly due to the slippage and loose coil in the automatic cutting process of the existing steel strap.
