Automatic scale breaking roller replacing mechanism of steel plate surface rust removing device

Abstract

The invention relates to an automatic scale breaking roller replacing mechanism of a steel plate surface rust removing device. The automatic scale breaking roller replacing mechanism comprises an upper beam, a main working beam, bearing pedestals and a scale breaking roller, wherein the main working beam moves up and down relative to the upper beam; the bearing pedestals are arranged at the two ends of the main working beam; the upper beam drives the main working beam to move horizontally; the bearing pedestals comprise the first bearing pedestal and the second bearing pedestal; the first bearing pedestal moves left and right relative to the main working beam; the two bearing pedestals are each provided with an elastic auxiliary mechanism; each elastic auxiliary mechanism comprises a base;each base drives an inner gear to rotate through a screw; a gear shaft is engaged in each inner gear; outer gears are fixed to the two ends of the scale breaking roller; and the exposed ends of the gear shafts retract inwards relative to the front end faces of the inner gears to reserve spaces. During roller assembling, the inner gears rotate and get close to the outer gears at the same time, theinner gears retreat under the pressure action of the outer gears when the inner gears and the outer gears are not engaged, and when teeth of the outer gears are aligned with gear tooth gaps of the inner gears, the inner gears reversely push under the elastic action to enable the outer gears to enter the spaces and be engaged with the inner gears. Manual work is replaced, and time and labor are saved.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to an automatic scale-breaking roller replacement mechanism of a steel plate surface derusting device. Background technique [0002] It often takes a period of time before the steel plate is produced and actually used. During this period, due to the properties of the steel plate itself, the surface of the steel plate will be rusted, which will affect the actual use. Rust treatment. [0003] At present, the method for removing rust on the surface of steel plates is generally pickling and rust removal. The principle is to use the acid in the pickling solution to chemically react with the metal oxide to dissolve the metal oxide and remove the rust and dirt on the steel surface. However, after the steel plate is pickled and derusted, it must be cleaned with a large amount of water and passivated. The large amount of waste water, waste acid, and acid mist fo...

[0004] Of course, there are also some physical rust removal methods. At present, the rust removal and polishing process on the steel plate surface in this technical field uses a disc brush or an abrasive belt rust removal mechanical device. Poor, the efficiency of rust removal is low and the surface of the steel plate cannot be fully cleaned; on the other hand, when the disc brush or the abrasive belt needs to be replaced due to wear and tear, it often requires manual operation for a long time, which is time-consuming and laborious

[0005] Now the scale-breaking roller is used to peel off or loosen the iron oxide scale on the strip steel billet to achieve the rust removal effect. The scale-breaking roller is equipped with a nylon material brush stick, which is used to grind the brush stick There will be gradual wear and tear. Therefore, the operation of changing the roll is required. Previously, manual assistance was required, which was very time-consuming, laborious and inefficient.
