Safety chuck device allowing wound and unwound roll materials to be conveniently stored, clamped and taken out

Abstract

The invention discloses a safety chuck device allowing wound and unwound roll materials to be conveniently stored, clamped and taken out. The safety chuck device comprises a drive end chuck and a supporting end safety chuck, and a mandrel or an expansion shaft is clamped between groove blocks at the shaft ends of the drive end chuck and the supporting end safety chuck. The safety chuck device hasthe advantages that the structure is compact, the design is reasonable, a threaded hole is formed in a clamping opening, and the length deviation of the gas expansion shaft or the mandrel can be compensated by adjusting the depth of a screw; the safety chuck device has high bearing capacity and is made of high-quality steel, and the bearing weight is greatly improved due to the special structure;the service life is long, maintenance is easy, the clamping opening is subjected to high-frequency quenching treatment, all parts can be exchanged for use, and thus maintenance is convenient; and theusage precision is high, the parts are chromeplated, blackened and quenched to achieve abrasion resistance, the parts are high in precision, high in deformation resistance and small in circular runout, irregular winding and overhigh pendulum amplitude of unwound rolls are effectively avoided, and thus the product quality can be prevented from dropping.

Description

technical field [0001] The invention relates to the technical field of winding and unwinding machinery, in particular to a safety chuck device that facilitates the placement and removal of winding and unwinding materials. Background technique [0002] According to the type, the safety chuck can be divided into shaft seat type, flange type, or horizontal installation and vertical installation. The simple, practical and easy-to-install design of the standard safety chuck provides fast, safe, reliable and simple coupling and disengagement operations for frequent actions such as coupling transmission and disengagement. [0003] The safety chuck provides a fast, accurate, simple and safe connection device for frequent connection, transmission and disengagement actions. It can be connected with air shaft or square steel. There are two installation methods, divided into shaft seat type and flange type. [0004] When installing the shaft seat type safety chuck, fix the foot seat,...

AI Technical Summary

Problems solved by technology

[0006] Since the current safety chuck is composed of a support end safety chuck and a transmission end safety chuck, and the roller mandrel is clamped between the support end safety chuck and the transmission end safety chuck, due to the different specifications of the mandrel and the wear and tear The end of the mandrel becomes shorter due to other reasons, resulting in a gap between the chuck and the mandrel, and the torque transmitted from the transmission safety chuck to the mandrel will increase, which will lead to uneven winding or unwinding. When rolling, the swing range of the roll increases, which brings inconvenience to the subsequent production and leads to a decrease in product quality, etc.
