The card clothing that is used for combing machine
The present invention relates to a kind of card clothing of form of the pin that is used for punching out combing machine, a toothed segment or saw tooth belt or compacting.
Such card clothing obtains its application in the machine of textile treatment and textiles processing, ribbon obtains combing there, so that fiber alignment and remove impurity.
Therefore the objective of the invention is, improve the result, particularly remove staple fibre and the impurity that (zurueckzuhalten) comb falls reliably.
Realize by such method that according to this purpose of the present invention promptly tooth or pin intersect with the combing direction in the zone that it freely protracts.
By reaching by this structure of the present invention, can spur fiber smoothly by card clothing, so thus on the other hand raising removes and combs the filter effect, the promptly feasible projected area that reduces free flow.Reduce the absolute value of combing waste material (Kaemmling) thus, this is more important than the long fiber composition that reduces in the combing waste material at the combing technical elements.The cotton seed hulls part is less stuck, so card clothing not quite too stops up, and reaches long service life because whole comb stress is less.
Imagine in another kind of structure of the present invention, tooth longitudinally successive in toothed segment or Saw blade alternately intersects to different directions.
Imagine in a kind of card clothing of being made up of the pin of punching out or compacting, the pin that is arranged side by side mutually of a pin bar or top comb intersects to same direction, i.e. their distributions that is parallel to each other.
The backstay (Riegel) of toothed segment or toothed segment is placed with respect to combing direction slight inclination ground in circular comb as everyone knows.By a kind of structure imagination of the present invention, the intersection of needle point and this obliquity overlaid.
In conjunction with the accompanying drawings the present invention is done more detailed explanation by means of preferred embodiment below.Wherein expression:
Fig. 1 presses the side view of fret-saw frame of the present invention,
Fig. 2 is along the cutaway view of II-II line among Fig. 1,
Fig. 3 is along the cutaway view of III-III line among Fig. 1,
The enlarged drawing in IV zone among Fig. 4 Fig. 2,
Fig. 5 has a view that the part of combing disconnects of the pin of punching out,
The vertical view of the narrow side of Fig. 6 top comb,
Fig. 7 one side view.
Local expression one fret-saw frame or sawtooth punching out part for no reason in Fig. 1 to 4, it has a base band 2 and a plurality of from the upwardly extending sawtooth 3 of base band.These sawtooth 3 are arranged in the plane usually in parallel to each other traditionally.
Different from therewith the present invention's imagination, the free end that tooth 3 protracts with respect to combing direction (arrow 4), just intersects with respect to the direction of relative movement between ribbon and the tooth 3 above base band 2.This means that tooth 3 is compiled with respect to the longitudinal axis 5 of this direction (arrow 4) or base band 2 changes an angle [alpha] and β.That is to say tooth 3 around its longitudinal axis, that is when comb circle during around a longitudinal axis, in top comb around one perpendicular to axis tilt longitudinally.Angle [alpha] is the same with β big in described embodiment, but extends along opposite direction with respect to the longitudinal axis 5.In other words alternately deflection or intersection to the left or to the right of tooth 3.
Expression one top comb in Fig. 5 to 7, it have many pins 3 ', they are in line mutually side by side, and are hidden by two cover plates 6,7.
Pin 3 ' have the free end 8 that protracts, that is the zone of playing combing effect, it is not hidden by cover plate 6,7.The pin of making the punching out metal sheet in these free end that protracts 8 zones intersects, and that is to say with respect to its bottom surface to distinguish crooked one identical angle.
