Description
Technical field
The present invention relates to the equipment on flat caiding machine capable or roller and clearer card, wherein have an operation element and/or function element at least, such as, fix combing element, rotary cap lath.The operation element of carding machine and/or function element have the load-carrying unit of elongation usually between two end regions for being supported on carding machine, this element has the region pointing to inner (in the working region of carding machine), and this region and Bearded-needle knitted cloth are oppositely arranged and are spaced from.
Background technology
In the carding machine nowadays designed, the combing element for carding process has the cover plate (revolving flats) of flexible needle cloth and/or has the fixing combing element of all-steel card clothing, and actual pin cloth is kept by high accuracy load bearing component.Extruded aluminium profile accustomed to using is as load bearing component now.This section bar has plurality of advantages, such as lightweight, rigidity is high, but also has its shortcoming, when being heated in side (situation as in carding process), they are towards side distortion of being heated.Parts are higher, and rigidity is larger, but it is also larger by being out of shape under heat effect.This distortion causes combing jaw no longer constant, and then the technology carding effect of making is not optimum.
Nowadays, for the form of carrying section bar in the extruded aluminium profile closed on all sides of combing element.The heat produced in carding process is fallen apart to the external world to a great extent by fixing combing element.Thermograde for this purpose and in required transverse section of section material causes fixing combing element to be out of shape.Gradient is larger, is out of shape also larger.
Such as, but heating not only makes to produce thermal expansion on the whole working width of carding machine, and the various parts causing carding machine multi-form all produce thermograde, and, the temperature on cylinder surface can reach 45 DEG C.The combing element relative with cylinder also reaches approximate temperature in Bearded-needle knitted cloth side, and the side of cylinder is deviated from combing element, due to reasons in structure (working width and precision due to parts), have the base of several centimetres high, temperature can reach obvious lower value (such as 28 DEG C).Therefore, the temperature difference on combing element have several degrees Celsius so large.Temperature extent depends on the character (structure, material) of element, the combing work (rotating speed, productivity ratio) carried out, the spacing of element and roller and the heat produced that how to leave.
It is lax that this thermograde causes element on carding machine width to produce.This relaxing makes the combing jaw at center narrower than outside, and cause combing jaw uneven, it broadens towards outside.Carding quality is reduced for this and/or the of inferior quality of cotton knot is untied.This also can cause fiber produce " side direction flyings ", namely fiber in marginal zone especially working width outside assemble, even deposit.This effect occurs on the carding machine with 1m working width, and working width is larger, and effect will be larger, and such as working width is greater than 1m, such as, when being 1.2m or larger.The change that above-mentioned effect produces can not be ignored, but concerns the problem of the overall carding quality of carding machine.Hot wire-CVD problem except mechanical relaxation increases with working width and becomes more serious.
Due in the carding machine course of work, fixing combing element and rotary cap lath become very hot, the extruded aluminium profile of fixing combing element or rotary cap lath (deviates from the side of cylinder) as cooling body outside it, is dispersed in surrounding air by its heat by free convection.As a result, little thermograde is produced in extrudate inside.Side towards cylinder is hotter, and therefore there is more expansion specific surface side laterally, and fixing combing element or rotary cap lath are bent to cylinder.This bending (and expansion of cylinder) makes the combing jaw of machine center narrow, and thus, fiber web becomes uneven, and quality is also deteriorated.In addition, also side direction flyings can be produced.
WO2004/106602A discloses a kind of element for carding machine, and this element at least contacts with fibrous material on side, and element has sag vertical curve on this side on the whole working width of carding machine.For this reason, active side is machined or aims at and produce spill.This element can be wrapped by element or the band element of shell, combing fragment, cover plate, the blade may with aspirator, induction element or operation element.Its shortcoming is, when machine is in cold state, produces and is preset as the identical sag vertical curve of all working state.The different heats produced in fibrous material (as cotton and/or the synthetic fiber) period that process is different can not be adjusted.
Summary of the invention
