Air floating type double-roller flexible paper unwinding frame

Abstract

The invention relates to the technical field of air floating type automatic paper unwinding, in particular to an air floating type double-roller flexible paper unwinding frame. Comprising a machine frame, a horizontal conveying plate is arranged at the top end of the machine frame, an avoiding gap is formed in the middle of the horizontal conveying plate in the direction perpendicular to the coated paper conveying direction, the paper unwinding device further comprises a paper unwinding mounting frame and two sets of flexible rollers, and the paper unwinding mounting frame comprises a first mounting groove and a first connecting bearing seat; the flexible roller comprises an inner shaft and outer shafts which are coaxially arranged, the two ends of the inner shaft are fixedly connected with the paper unwinding mounting frame through two first connecting bearing seats correspondingly, an air injection driving device used for driving the outer shafts to rotate is arranged in the inner shaft, and a working gap allowing coating paper to penetrate through is reserved between the two outer shafts. The paper unwinding process is achieved through the air floating type flexible rollers, the friction force between the flexible rollers and the surface of paper can be automatically and accurately adjusted during paper unwinding, it is guaranteed that the surface of the paper is not damaged, the layer number of the paper passing through the flexible rollers is automatically and accurately detected, the distance between the flexible rollers is controlled accordingly, and the paper unwinding precision is improved.

Description

technical field [0001] The invention relates to the technical field of air-floating automatic paper unwinding, in particular to an air-floating double-bar flexible paper unwinding stand. Background technique [0002] The unwinding stand is a commonly used equipment in the paper industry. The traditional unwinding stand adopts hydraulic ejector type unwinding, and the hydraulic arm is cast iron. [0003] The unwinding stand in the prior art has a relatively large and constant friction force on the paper during the paper pushing process, which is easy to damage the paper and cause economic losses, and the unwinding stand in the prior art cannot accurately detect the number of sheets passed through, The frictional force during the paper-backward process cannot be adjusted automatically. [0004] Therefore, it is necessary to design an air-floating double-rod flexible unwinder to solve the above problems. SUMMARY OF THE INVENTION [0005] Based on this, it is necessary to pr...
