Mounting structure of opening rubber roller of filter stick forming machine

Abstract

The invention relates to the technical field of filter stick forming machines, in particular to a mounting structure of an opening rubber roller of a filter stick forming machine. The mounting structure comprises a large support for mounting the opening rubber roller and a small support for connecting a fixed support; the large support is provided with a first end and a second end which are positioned on two sides of the axis of the opening rubber roller respectively; the first end is movably connected with a driving piece through a hinge piece; the second end is hinged to the small support through a hinge shaft; and the axis of the hinge shaft is perpendicular to the axis of the opening rubber roller in the horizontal plane. Through the split structure that the large support is hinged to the small support, and the movable connection between the large support and the driving piece, the large support can drive the opening rubber roller to rotate in the direction perpendicular to the axis of the opening rubber roller in the vertical plane relative to the small support and the driving piece, so that the self-adjustment of the parallelism of the opening rubber roller and a threaded roller is achieved, the error of the parallelism of the opening rubber roller and the threaded roller cannot be generated, and the opening quality of a tow belt can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of filter rod forming machines, in particular to an installation structure of an opening rubber roller of a filter rod forming machine. Background technique [0002] In the filter rod forming process, the opening of the tow is mainly to make the tow belt successively pass between the front and rear two sets of opening rubber rollers and the threaded rollers, and through the change of the speed of the front and rear opening rubber rollers, the surface of the opening rubber rollers is relatively small. The large coefficient of friction makes the tow belt stretch under a certain pressure, turning the raw silk belt into a loose tow. The uniformity of the stretching of the tow belt and the thickness of the tow belt directly affects the suction resistance and hardness quality index of the filter rod, and the parallelism of the axes of the opening rubber roller and the threaded roller determines the degree of stabi...

AI Technical Summary

Problems solved by technology

This method cannot completely eliminate the parallelism error between the opening rubber roller and the threaded roller. Generally, there is an error of 0.05mm-0.10mm in the parallelism between the opening rubber roller and the threaded roller after more accurate adjustment.

Since the front and rear opening rubber roller brackets are hinged and connected to the fixed bracket, after the installation is completed, the opening rubber roller bracket can only move up and down with the opening rubber roller driven by the cylinder to make the opening rubber roller Play the role of pressing the tow belt, can not change the parallelism of the opening rubber roller relative to the threaded roller, and can not make the same degree of compression of each part of the tow belt when the opening rubber roller is worn

As a result, the tow belt is stretched on the outer circumferential surface of the opening rubber roller with uneven pressure for a long time, and cannot be opened evenly in thickness, and because the pressure at the gap between the opening rubber roller and the threaded roller changes. If the friction force is small, the friction force will become smaller, resulting in faster wear. When the wear reaches a certain level, it is necessary to replace the opening rubber roller to meet the product quality requirements.
