Tension-adjustable two-roller active scutching device

Abstract

The invention provides a tension-adjustable two-roller active scutching device which comprises a rack, an integral frame, a transmission mechanism, an upper scutching roller and a lower scutching roller; the integral frame comprises a left fulcrum, a right fulcrum, a left lateral plate, a right lateral plate and a connecting prop; the middle parts of the left lateral plate and the right lateral plate are connected into a rigid integral by the connecting prop; the left fulcrum and the right fulcrum are respectively mounted at outsides of the left lateral plate and the right lateral plate, and respectively propped by a bearing seat and a worm gear reducer; the upper scutching roller and the lower scutching roller are mounted between the left lateral plate and the right lateral plate in symmetry with the connecting prop as the center; the transmission mechanism comprises a decelerating motor, an upper scutching roller gear, a lower scutching roller gear and transition gears; and the decelerating motor and the upper scutching roller gear are connected, the upper scutching roller gear mounted on the upper scutching roller is connected with the lower scutching roller gear mounted on the lower scutching roller via a pair of transition gears. The invention is reasonable in structure, convenient in operation, and simple in tension adjustment, the two rollers have equivalent speed and no tension difference, and the scutching and de-wrinkling effects are good.

Description

Technical field [0001] The invention relates to an opening device, in particular to a double-roller active opening device with adjustable tension. Background technique [0002] At present, during the processing of webs, films, non-woven fabrics, woven fabrics and other roll materials, it is often necessary to be equipped with active opening devices. Most of the active opening mechanisms currently in use are single-roller active opening devices. In order to better open and flatten the web, a dual-roller active opening mechanism is usually used. However, the existing dual-roller active opening mechanism only It is a combination of two sets of single-roller opening devices, which not only increases equipment investment, but also is inconvenient to operate. The two sets of single-roller opening devices also have the problems of speed difference that is not easy to adjust, and the ideal opening effect is not ideal. Summary of the invention [0003] In order to overcome the shortcoming...

Most of the active opening mechanisms currently used are single-roller active opening devices. In order to better flatten the coil material, it is usually necessary to use a double-roller active opening mechanism. However, the existing two-roller active opening mechanisms only It is a combination of two sets of single-roller opening devices, which not only increases equipment investment, but also is inconvenient to operate. The two sets of single-roller opening devices also have the problems of difficult adjustment of speed difference and unsatisfactory opening effect.
