Abstract
The utility model relates to a fiber bundle loosening device, which comprises a pre-tension roller pair, an input roller pair, a stretching roller pair and a steering roller pair. The engagement tangent line of the steering roller pair is in the same straight line with the engagement tangent line of the input roller pair and the stretching roller pair. A collection roller driven by a drive motor is arranged between the steering roller pair and the stretching roller pair. The axis of the collection roller is positioned below the engagement tangent line of the steering roller pair. According to the technical scheme of the utility model, a fiber bundle is stretched, expanded and collected by means of a loosening mechanism. Therefore, the fiber bundle is higher in power curve and more stable in suction resistance, so that a filter stick of a higher quality can be obtained.
Description
Technical field
The utility model relates to a kind of fibre bundle fibre-opening unit having, for fibre bundle being upset to curling arrangement, thereby obtains effective shredding also finally for forming machine is produced the ready a kind of device of filter stick for cigarettes.
Background technology
At present domestic existing 400 meters of fibre bundle opening mechanisms exist because of phenomenons such as insufficient the produced moulding filter stick for cigarettes resistance to suction of tow opening are unstable.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of fibre bundle fibre-opening unit having, and this opening mechanism is by tow is stretched, expands, collected, thereby makes tow obtain higher power curve and more stable resistance to suction, obtains higher-quality filter stick.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: a kind of fibre bundle fibre-opening unit having, comprise tension rollers to, input roller to, worm felt roll to slewing rollers pair, the engagement tangent line between slewing rollers pair and input roller to the right engagement tangent line of worm felt roll on same straight line; Slewing rollers pair and worm felt roll between be also provided with the collecting drum being driven by drive motors, the axis of collecting drum is positioned at the below of slewing rollers to engagement tangent line.
This fibre bundle fibre-opening unit having adopts increases collecting drum on original mechanism basis, makes tow opening apart from increasing, and tow progresses into forming machine through the transition of collecting drum, makes tow mobile phone obtain buffering, and simple in structure, workable.
Accompanying drawing explanation
Fig. 1 is the structural representation of fibre bundle fibre-opening unit having.
Fig. 2 is the A-A cutaway view of Fig. 1, the i.e. structural representation of collecting drum.
The specific embodiment
As shown in Figure 1, a kind of fibre bundle fibre-opening unit having, comprise tension rollers to 5, input roller to 4, worm felt roll to 3 and slewing rollers to 1, the engagement tangent line between slewing rollers pair and input roller to 4 and worm felt roll to 3 engagement tangent line on same straight line; Slewing rollers to 1 and worm felt roll be also provided with the collecting drum 6 being driven by drive motors between to 3, the axis of collecting drum 6 is positioned at the below of slewing rollers to 1 engagement tangent line.This collecting drum is the V-groove roller without clamping force.
As shown in Figure 2, the axle center of collecting drum 6 is connected with the rotating shaft of drive motors 9, and drive motors 9 is connected with fibre bundle fibre-opening unit having with pivot flange 8 by gripper shoe 10, thereby guarantees drive motors 9 even runnings.
Its concrete course of work is: tow first through tension rollers to 5 pretensions after, enter input roller to 4 and worm felt roll to 3, carry out shredding, then through slewing rollers, to 1, turn to, then collect through collecting drum 6, finally enter the formation system moulding of forming machine." pulley " effect due to collecting drum, makes tow constant tension when entering forming machine forming cavity, extended simultaneously input roller to 4 and worm felt roll to 3 spacing, reduced the function influence of pulling force to fibre bundle, it is retained certain curling and unlikely impaired.
