Speed-variable cutting integrated paper feed roll for paper machine

Abstract

The invention provides a speed-variable cutting integrated paper feed roll for a paper machine. The speed-variable cutting integrated paper feed roll comprises the paper feed roll, a belt pulley, a linking rod, limiting guide slots, a cutter, a variable speed loop bar, a limiting extension sleeve, a first right-angled transmission gear, a second right-angled transmission gear, a third right-angled transmission gear, an output end rod, a cutting port, fixed gears, touch surfaces, piston rods, passive plates, a change gear, linkage limiting teeth and a linkage limit groove, wherein the surface of the paper feed roll is provided with the cutting port in an open manner; the belt pulley is integrally arranged on one side of the paper feed roll. The first right-angled transmission gear is linked with the second right-angled transmission gear and the third right-angled transmission gear, and further the linking rod changes the rotating speed by using the rotating speed of the paper feed roll, and the device cuts more accurately; the cutting time of the cutter is prevented from being affected whether the rotating speed of the paper feed roll is increased or reduced, so that the device is simpler in control and lower in fault rate.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a variable speed cutting integrated paper feed roller for a paper machine. Background technique [0002] The complete set of equipment that makes pulp into paper web is collectively called a paper machine, including headbox, wire section, press section, drying section, calender, reel, transmission section and other hosts and steam, water, Auxiliary systems such as vacuum, lubrication, heat recovery, etc. [0003] The paper feed roller is a transition piece that transports the paper to the paper cutting system after the paper is formed, but the current cutting of the paper is to use the paper feed roller to cut while conveying, while the existing cutting system uses two power One component provides power to the paper feed roller, and the other provides power to the cutting knife, and this situation causes the paper feed roller to be used. It is necessary to control two power ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a variable-speed cutting integrated paper feed roller for a paper machine, so as to solve the problem of laborious control of two power outputs, and when the rotation of the paper feed roller increases or decreases, the cutting knife cannot be matched quickly and synchronously. The rotation speed of the paper feed roller causes the problem that the cutting position of the cutting knife is not accurate enough
