Tow extending device on KDF4 forming machine unit

Abstract

The invention provides a tow extending device on a KDF4 forming machine unit. The tow extending device on the KDF4 forming machine unit comprises a braking roller, an input roller, an extending roller, a guide roller and a pre-forming roller in sequential arrangement in the tow transmission direction, wherein the braking roller is arranged on the machine frame; an installing hole is formed in a position, corresponding to the end part of the braking roller, on the machine frame; a tow position limiting stop block is arranged on the installing hole, and comprises a threaded seat and a screw rod;a through hole is formed in the threaded seat in the axial direction; one end of the screw rod is connected with the through hole; the other end of the screw rod is connected with a screw cap; the threaded seat comprises a body and a flange extending out from one side of the body in the axial direction; and a rotatable stop roller is arranged on the flange. The tow extending device on the KDF4 forming machine unit related by the invention can achieve the goal of reducing the machine unit halt frequency due to tow damage fracture caused by long-time friction temperature rise of the stop blockand a tow; the production continuity is guaranteed; the effective operation rate of the equipment is greatly improved; meanwhile, the product quality is improved; and the loss is reduced.

Description

technical field [0001] The invention relates to the technical field of a cigarette filter rod, in particular to a tow stretching device used on a KDF4 forming unit. Background technique [0002] The working principle of the KDF4 filter rod forming unit in the prior art to produce filter rods is to open the tow, spray glycerin ester, wrap the molding paper, cut the cutter head and other processes, and then push the filter rods into the filter rods by the accelerator disk In the slot of the smoke wheel, the suction air makes the pushed filter rod decelerate, calibrate, stay on the grooved drum and transport it to the transfer wheel, which uses the suction air to receive the filter rod and transfer it To the conveyor belt, enter the tray system for tray loading and packaging. [0003] At present, the function of the tow stop installed on the two-stage opening roller is to fix the position of the tow after being fully opened, so as not to make it deviate from the normal positio...

AI Technical Summary

Problems solved by technology

Long-term friction can easily cause the temperature of the block to rise, thereby increasing the wear of the tow, and frequent automatic shutdown of the tow break unit
