Slitting machine

Abstract

A slitting machine is used for slitting paper webs. The slitting machine comprises a first traction mechanism, a second traction mechanism, a buffer mechanism and a cutting mechanism. The second traction mechanism and the buffer mechanism are arranged between the first traction mechanism and the cutting mechanism. The buffer mechanism is arranged between the first and second traction mechanisms. The second traction mechanism is arranged between the buffer mechanism and the cutting mechanism. The second traction mechanism is used for changing the conveying speed of the paper webs according to the cutting requirement. The buffer mechanism is used for reserving or releasing the paper webs according to the cutting requirement. Compared with the prior art, the traction mechanisms and the buffer mechanism matched with the traction mechanisms are arranged, the traction mechanisms are used for tracking the cutting mechanism so as to change the feed amount of the paper webs, and therefore the cut paper webs of different specifications are obtained. The slitting machine has the advantages of being low in energy consumption, small in vibration and capable of reducing noise.

Description

technical field [0001] The invention relates to the field of slitting web materials such as paper, in particular to a slitting machine capable of cutting various specifications of web materials such as paper. Background technique [0002] The slitting machine usually includes components such as an unwinding mechanism, a traction mechanism and a cutting mechanism. A cutting mechanism of an existing slitting machine for slitting paper includes two cutter units, which can cut papers of different sizes on one production line. [0003] The driving motor of the cutter unit can be a frequency modulation motor or a servo motor according to different needs, and the power is generally between 38KW and 62KW. The traction mechanism is used to pull the paper to run. The driving motor of the traction mechanism is generally a frequency modulation motor with a power ranging from 11KW to 21KW. The two cutter units operate at high and low speeds relative to the traction mechanism, and synch...

AI Technical Summary

Problems solved by technology

When the cutter unit is synchronized with the traction mechanism and after the synchronization, the power loss at the moment of starting and braking is huge, and a considerable part of the energy is consumed in the form of heat through components such as resistors or capacitors.

This energy-intensive production method for paper processing does not meet the current requirements for energy conservation, emission reduction, and green development, and seriously restricts the development and progress of enterprises.

In addition, the noise and vibration caused by the cutter unit at the moment of starting / braking are unfavorable factors, which affect the working environment and machine life
