Abstract

The invention discloses a banding moving object tightening differential adjustment method, which comprises the following steps: monitoring bias condition of banding moving object and reducing tensile force of stretch roll in bias direction. The device comprises bias sensor, stretch roll and tensile force driving device connected with the two sides of stretch roll. Bias sensor connects control device of tensile force, via which tension-adjusting gear connects with tensile force driving device. Compared with existing technology, the greatest difference is that, according to bias condition of banding moving object, the invention adjusts tensile force of tension roll in time to ensure tensile force bias of the two sides and achieve correcting error. The invention has the advantages of simplicity of structure, low error rate, high reliability, no limitation of width of banding moving object, wide application area and so on.

Description

Technical field: [0001] The invention relates to a deviation-correcting method and equipment for a belt-shaped moving object, in particular to a method and equipment for adjusting the deviation-correcting tension difference of a belt-shaped moving object with simple structure, wide application range and good deviation-correcting effect. Background technique: [0002] At present, in metallurgy, chemical industry, printing, printing and dyeing, environmental protection and other industries, there is a belt movement process. For example, the sludge dehydration in the environmental protection industry uses a filter belt dehydrator with a belt movement process. The filter belt dehydrator uses upper and lower filter belts with strong water permeability. Through the gravity, pressing force and shear force between the two filter belts, the water in the mud is pressed out to achieve the purpose of sludge dehydration. The upper and lower filter belts are the moving belts. During the ...
