Guiding pinch straight head roll device

Abstract

The invention relates to a guide pinch straight head roller device, in particular to an auxiliary device in the front of a broadband narrow-trip wrap-up machine used on a broadband slitting line. The device is characterized in that a material guide plate assembly is hinged with a guide roller shaft and the material guide plate can rotate around the guide roller shaft under the action of a hydrocylinder. A guide roller is connected to a machine seat through a guide roller bearing and a bearing seat. Both ends of a pinch straight head roller are provided with a pinch roller bearing and the bearing seat respectively, and one end of the pinch straight head roller is provided with a hydraulic motor. The pinch roller bearings and the bearing seats can slide in a left frame and a right frame, and synchronous connecting rods are arranged on the two pinch roller bearings and the bearing seats. A pinch roller swinging cylinder is arranged on the frames, and a piston rod is connected with the pinch roller bearings and the bearing seats. A pinch roller pressing cylinder is arranged on the frames and the piston rod is hinged with the pinch roller bearings and the bearing seats. The device has the advantages of high response speed, short correction time and high sensitivity, and can greatly reduce manual auxiliary working time and improve the wrap-up quality of broadband materials.

Description

technical field [0001] The invention relates to a guide and pinch straight head roller device, in particular it is used in a wide-band strip processing (rolling, recoiling, slitting or surface treatment, etc.) Auxiliary device before the strip winder. Background technique [0002] In the prior art, the wide-band strip processing (rolling, recoiling, slitting or surface treatment, etc.) production line, especially the wide-band narrow strip coiler used on the wide-band slitting line, often has a large structure. At present, the traditional single-roller guide mechanism is generally used in front of this kind of winder, and a large amount of manual assistance must be relied on when threading the tape, which increases the auxiliary man-hours and reduces the quality of strip winding. In extreme cases (such as: strip Very thin, slit into many narrow strips, etc.), it is even difficult to complete the threading. Contents of the invention [0003] The object of the present inve...
