Description
Technical field
The present invention relates to the equipment on flat caiding machine capable or the roller and clearer card, wherein have an operation element and/or function element at least, for example fixedly 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 that are used to be supported on the carding machine; This element has the zone of pointing to inner (in the working region of carding machine), and this zone and Bearded-needle knitted cloth are oppositely arranged and are spaced from.
Background technology
In the carding machine of design nowadays, the combing element that is used for carding process is cover plate (revolving flats) with flexible card clothing and/or the fixedly combing element with all-steel card clothing, and actual card clothing is kept by the high accuracy load bearing component.Custom uses extruded aluminium profile as load bearing component now.This section bar has plurality of advantages, and is for example in light weight, rigidity is high, but its shortcoming is also arranged, and when when a side is heated (as the situation in the carding process), they are towards the side distortion of being heated.Parts are high more, and rigidity is big more, but it is receiving under the heat effect distortion also bigger.This distortion causes the combing jaw no longer constant, and then makes that technological carding effect is not optimum.
Nowadays, the carrying section bar that is used for combing element is the form of the extruded aluminium profile of on all sides, sealing.The heat that produces in the carding process is through fixedly combing element is diffusing to a great extent to extraneous.For this purpose and the thermograde in the essential transverse section of section material causes fixedly combing element to be out of shape.Gradient is big more, is out of shape also big more.
Yet heating not only makes and on the whole working width of carding machine, produces thermal expansion, and causes the multi-form various parts of carding machine all to produce thermograde, and for example, the temperature on cylinder surface can reach 45 ℃.The combing element relative with cylinder also reaches approximate temperature in the Bearded-needle knitted cloth side; And deviate from a side of cylinder at combing element; Owing to reasons in structure (because working width and precision of parts), have several centimetres high base, temperature can reach obviously than low value (for example 28 ℃).Therefore, the temperature difference on the combing element has several degrees centigrade so big.The temperature extent depends on the spacing of the character (structure, material) of element, the combing work (rotating speed, productivity ratio), element and the roller that are carried out and the heat that how to leave and produce.
It is lax that this thermograde causes on the carding machine width element to produce.This relaxing makes that the combing jaw at center is narrower than the outside, causes the combing jaw inhomogeneous, and it broadens towards the outside.This makes carding quality reduce and/or the of inferior quality of cotton knot untied.This also can cause fiber to produce " side direction flyings ", and promptly fiber is distinguished especially outside gathering of working width even deposition on the edge of.This effect occurs on the carding machine with 1m working width, and working width is big more, and effect will be bigger, and for example working width is greater than 1m, for example is 1.2m or when bigger.The variation that above-mentioned effect produces can not be ignored, but concerns the problem of the whole carding quality of carding machine.Hot relaxation problem except mechanical relaxation becomes more serious with the working width increase.
Because in the carding machine course of work; Fixedly combing element and rotary cap lath become very hot; Fixedly the extruded aluminium profile of combing element or rotary cap lath, is dispersed into its heat in the surrounding air through free convection as cooling body in its outside (side that deviates from cylinder).As a result, in the little thermograde of the inner generation of extrudate.Side towards cylinder is hotter, so a specific surface side laterally has more expansion, makes fixedly combing element or rotary cap lath to the cylinder bending.This bending (and expansion of cylinder) narrows down the combing jaw of machine center, and thus, it is inhomogeneous that fiber web becomes, and quality is variation also.In addition, also can produce the side direction flyings.
WO 2004/106602A discloses a kind of element that is used for carding machine, and this element contacts with fibrous material on a side at least, and element has sag vertical curve on the whole working width at carding machine on this side.For this reason, active side is by machined or aligning and produce spill.This element can be by element, combing fragment, cover plate, the blade that possibly have aspirator, induction element or the operation element of packing element or band shell.Its shortcoming is that when machine was in cold state, generation was preset as for the identical sag vertical curve of all working state.Can not be adjusted at and handle the different heats that produce during the different fibrous materials (like cotton and/or synthetic fiber).
