Description

Multi-roller clamping and conveying straightener Technical Field The invention relates to the technical field of cold rolling treatment equipment, in particular to a multi-roller pinch straightening machine. Background The straightening machine is one of professional equipment for adjusting the shape of a strip and a plate, and comprises a frame, a plurality of top straightening rollers, a plurality of bottom straightening rollers, at least two pinch rollers (the bottom pinch rollers and the top pinch rollers), a straightening roller top carrier, a pinch roller top carrier and a pinch roller top carrier, wherein the straightening roller top carrier is positioned on the frame and used for driving the top straightening rollers to move up and down, the straightening roller top carrier is positioned on the frame and used for driving the top pinch rollers to move up and down, and side openings which are convenient for loading and unloading the rollers are arranged on the frame on the side surface of the straightening machine. In the prior art, a hard rod body with a transverse rod-shaped main body and ventilation grooves arranged at the top and/or the bottom is arranged on a rack in general, and the roller is cleaned and maintained (dedusted) regularly and automatically in a blowing or sucking mode, but due to the self structure, the air inlet and outlet positions are difficult to flexibly adjust, more air inlet and outlet positions are required to be arranged to barely meet the use requirement, the cost is high, and the maintenance difficulty is high. The rollers are in direct contact with the strip steel in the rolling production process, gradually wear in the operation process, and the rollers need to be replaced regularly in order to ensure the product quality; When the straightening machine changes rolls, the top straightening roller carrier is controlled to move downwards so as to be placed on the bottom straightening roller (the upper roller system is enabled to fall on the lower roller system), then the top straightening roller is detached from the top straightening roller carrier, after bearings and bearing supports on the top straightening roller are detached, the top straightening roller is pulled out of side ports one by one manually, and the detached rollers are carried away by using a clamp roll changing device or a lifting device so as to leave a space for detaching the bottom straightening roller; The roll replacing process by means of the roll replacing equipment is relatively complicated, the adjusting and controlling difficulty is high (particularly, when the top pinch roll is replaced, the space is small, the operation difficulty is high), the efficiency is low due to the operation difficulty, and the dangerous roll is high and easy to damage due to manual operation when the roll is pulled out and pushed in. Therefore, a multi-roller clamping and conveying straightener which can automatically and conveniently remove dust without arranging more dust removing equipment, is convenient and efficient to change rollers and is not easy to damage the rollers during roller changing is needed. Disclosure of Invention The technical problems of high maintenance difficulty and poor dedusting effect of the dedusting functional parts of the straightener and the technical problems of high roller changing difficulty, complex process, high danger and low efficiency in the prior art are solved by the multi-roller clamping straightener, and the technical effects that the multi-roller clamping straightener can automatically, efficiently and conveniently remove dust, is convenient and efficient to change rollers and is not easy to damage rollers during roller changing are achieved without arranging more dedusting equipment. The embodiment of the application provides a multi-roller pinch straightener, which comprises a rack, a straightening roller set, a pinch roller set, a bottom lifting shifting assembly, a carrying roller assembly, a dust removing assembly and a temporary lifting assembly, wherein a side opening is arranged on the rack; a mounting position of the temporary lifting component is arranged on the frame close to the bottom of the side opening; the bottom lifting shifting component is positioned at the bottom of a roller of the multi-roller clamping and straightening machine and is used for changing the space positions of the roller carrying component and the dust removing component carried by the self through self movement and deformation; The support roller assembly is positioned at the top of the bottom lifting and shifting assembly and comprises a top supporting plate and a bottom wheel body positioned on the top supporting plate, wherein the top supporting plate is a transversely-arranged hard plate body, and the longitudinal section of the top supporting plate is arc-shaped and the opening of the top supporting plate is upward; The dust removing component removes iron oxide powder adhered on the
