Description

Revolving flat for waste-silk card

The utility model belongs to the special part of textile machine, particularly a kind of carding machine revolving flats.

The carding machine revolving flats is crucial carding element, and it has finished the most careful and intimate last combing with cylinder, is determining the quality of product.In view of the special status of revolving flats at the special part of textile industry conduct, be to improve to divide the comb quality, it just becomes the professional manufacturer in countries in the world and uses factory to study the focus and the focus of transformation.Adopted as Japan and other countries specialty manufacturer and to have presorted the comb securing cover plate, be used for alleviating the operating pressure of revolving flats, improve the purpose of dividing the comb quality to reach, but, its pin tooth can not keep sharp keen, fill brokenly phenomenons such as seed, operation is inconvenient, obstruction is squeezed oneself into a croweded bus and perplexing people always, therefore, fail to be extensive use of.At present, the main direction of expert's research both at home and abroad mainly is to plant needle material, plant the aciculiform shape, plant the faller gill row, tempering aspect such as maintenance, though obtained certain effect, all do not having the breakthrough of matter.As facet at flat-clothing card wire heel end mill 2.5～3mm, space, improve branch comb quality though can reduce the branch comb,, all do not control big facet at present both at home and abroad and once temper successful experience, if adopt and temper for twice syntheticly, increased recruitment and labour intensity, and can not ensure the quality of products, in case connect pin, not only temper difficulty, two dial precision are difficult to guarantee that the card clothing life-span shortens greatly, therefore, mill facet cover plate also fails to promote.In a word, the transformation to this important step of physical dimension of cover plate own has all been left in above-mentioned corrective measure, and in the last hundred years, the geometry of cover plate does not almost change.At present, the revolving flats of domestic most carding machines is that poor (0.84～0.9mm), the gagger width is 33.3mm to big heel toe, and it is 22mm that card clothing is planted the pin width.Its major defect is: 1. cover plate and cylinder on average space greatlyyer, space that it is bigger to change, and divide comb second-rate, divide the comb quality if improve, and take tightly to space technology, very easily cause to connect pin, make card clothing be difficult to repair, and can reduce branch comb quality on the contrary; 2. traditional correction position that spaces can cause artificial amplification to space because of the easily random pin of card wire heel end pin, reduces and divides the comb quality; 3. big, the weight of cover plate size greatly, consume material more, cause zero, component wear is big, service life is short.

The purpose of this utility model is at the deficiencies in the prior art, and provide a kind of cover plate and cylinder on average to space little and change mild, divide the comb quality higher carding machine revolving flats.Its card clothing work gross area and size and existing homemade carding machine are basic identical, and flat-clothing divides the comb load constant substantially, is suitable for the supporting and improving old machine of homemade new machine.

The purpose of this utility model is achieved through the following technical measures: a kind of carding machine revolving flats that is made of cover plate gagger and flat-clothing, mainly be that cover plate gagger heel toe difference is changed into: 0.40～0.54mm, branch comb after the change spaces and changes gently, on average spacing than heel toe difference is that the cover plate of 0.84mm descends more than 45%, cover plate and cylinder point of contact on cover plate card covering needling from card wire a distance of card wire heel end, branch comb quality be can obviously improve, cotton knot and fault reduced.

The further technical measures of the utility model are: adopt further preferred cover plate gagger heel toe difference and gagger width, heel toe difference is 0.42～0.46mm, and the gagger width is 29.5～30.5mm.With this understanding, divide comb to space to change the common cover of more slowly, on average spacing and descend more than 55% than big heel toe poor (0.84mm).Both can significantly improve branch comb quality, can guarantee again the gagger width that suits can not increase the flat-clothing load.Because heel toe difference is bad too greatly, the too little flat-clothing that can increase is loaded, and can reduce branch comb quality on the contrary.Gagger width suitably reduction can make the reduction of on average spacing, and also can save material, but the gagger width is too narrow also not all right, because of the gagger width directly affects the cover plate card covering needling width, plants too narrow its branch comb that can increase of pin width and loads, and influence divides combs quality.In addition, too narrow its intensity of gagger width also can reduce.

Another technical measures of the present utility model are: along with cover plate gagger narrowed width, the cover plate card covering needling width is also corresponding to be reduced, when the cover plate gagger is called in person the toe difference at 0.42～0.46mm, the gagger width is when 29.5～30.5mm, card clothing is planted the pin width and is chosen as 19.6～20.4mm, and card wire heel end distance cover plate gagger heel end distance is 3.8～4.2mm from (needleless district).Plant the pin position change, suitable width, to be equipped with preferred heel toe poor, changed the conventional cover plate correction position that spaces, becoming the side of spacing a little has tight point to be both sides all have tight point (when having avoided effectively that correction is spaced on card wire heel end line, because of the artificial amplification that the easy random pin of heel end line causes is spaced, thereby the phenomenon that causes branch comb quality to descend takes place).Simultaneously, space about the 1.5mm after spacing a little and tightly distinguish, can grip or discharge lentamente fiber effectively, the characteristics of utilizing two cover plates distance to dwindle prevent to amplify suddenly because of the space, and it is too high that fiber is floated repeatedly, cause time of staying weak point on the cover board, transfer number too much is twisted into cotton knot repeatedly between cylinder and cover plate, is perhaps taken out of the cover plate workspace in the same commentaries on classics of cylinder, perhaps directly takes the cover plate workspace out of by cylinder and reduces branch comb quality.

When adopting abovementioned technology, divide comb quality, the utility model also to take these technical measures of facet of tempering into 2.5～3mm apart from a few row's pins of heel end place at flat-clothing for further improving.

Below in conjunction with accompanying drawing the utility model embodiment is described in further detail.

Fig. 1 is the utility model cover plate and cylinder relative position schematic diagram;

Fig. 2 is common cover and cylinder relative position schematic diagram;

Fig. 3 is the coordinate diagram of cover plate gagger width and the average mark comb relation of spacing.

With reference to Fig. 1, the utility model cover plate gagger (1) width EF is 30mm, and heel toe poor (m-n) is 0.44mm, and the aspect ratio common cover suitably reduces, and other physical dimensions are basic identical; It is 20mm that flat-clothing (2) is planted pin width B C, and card wire heel end distance cover plate gagger (1) heel end distance is from BE(needleless district) be 4mm, it is 1.5mm apart from BA that cover plate and cylinder (3) point of contact A holds the B point to the card wire heel.

M be cylinder (3) to cover plate toe-end distance, n be cylinder (3) to cover plate heel end distance from, cover plate heel toe difference then of the present utility model can be calculated by following formula:

$m-n=\sqrt{{\mathrm{AF}}^2+R^2}-\sqrt{{\mathrm{<figure-callout\; id="2"\; label="AE"\; filenames="942259637\_DRIMG2.png"\; state="\{\{state\}\}">AE</figure-callout>}}^2+{\mathrm{<figure-callout\; id="2"\; label="R"\; filenames="942259637\_DRIMG2.png"\; state="\{\{state\}\}">R</figure-callout>}}^2}$ ……（1）

R is cylinder (a 3) radius (645mm) in the formula, and the heel toe that can draw 0.44mm in the above-mentioned relevant data substitution formula (1) is poor.

Among Fig. 1, establish the D point on flat-clothing (2) dial more arbitrarily, the x that spaces of D point and cylinder (3) can be obtained by following formula:

x＝ $\sqrt{{(\mathrm{BD}-\mathrm{BA})}^2+R^2}$ －R……（2）

In relevant data substitution formula (2), space numerical value and the average mark comb that both can obtain each point on flat-clothing (2) dial and cylinder (3) value of spacing.

With reference to Fig. 2, when cover plate heel toe difference is 0.84mm, cylinder (3) is at cover plate gagger (1) heel end with the point of contact of cover plate, and still, flat-clothing (2) card wire heel end distance cover plate gagger heel end has 5.6mm needleless district, so, cylinder (3) and flat-clothing (2) dial space when being zero at the heel end, and cover plate dial and cylinder (3) are not tangent, are planting under the wide more situation of pin width, it is obvious more to plant the variation of spacing in the pin width, and it is big more on average to space.

Fig. 2, establish the D point on the cover plate dial more arbitrarily, the D point can be obtained by following formula to the x that spaces of cylinder (3):

x＝ $\sqrt{{(\mathrm{BD}+\mathrm{AB})}^2+{\mathrm{OA}}^2}$ －R……（3）

(3) OA=in the formula

, R is cylinder (a 3) radius (645mm), in relevant data substitution (3) formula, can obtain each point and cylinder (3) on the cover plate dial space and the average mark comb spaces.Subordinate list is called in person on average spacing of toe difference cover plate dial and cylinder (3) for the difference that is calculated by formula (2), formula (3).

Subordinate list unit: mm

Find from table 1: the toe difference of calling in person greatly cover plate is compared with other heel toe difference, and it on average spaces is respectively their 1.814 times, 1.928 times, 2.767 times, and card wire on average spaces in 6mm apart from the heel end distance and is respectively 4.388 times, 5.181 times and 14 times.Finding in the calculating that the utility model cover plate spaces changes slowly especially, and almost constant in the both sides, point of contact, the branch that tightly spaces comb becomes a reality finally.

Find in the test: when spinning No. 14.6 cotton yarns, adopt the little heel toe of 0.55mm difference cover plate to compare with the big heel toe of 0.84mm difference cover plate, cotton knot and fault sum reduce by 27.66% and 17.22% respectively.The cover plate heel toe difference scope that the utility model is selected is between 0.40～0.54mm, and it on average spaces littler, divides the comb quality further to improve.

With reference to Fig. 3, topmost a curve is represented conventional cover plate, it and cylinder (3) point of contact on cover plate gagger (1) heel end line, from top to bottom the cover plate of second to the 4th curve representative and cylinder (3) position, point of contact on the cover plate dial with card wire call in person end distance separate be not 0,1.5mm, 2mm.Above-mentioned four curves all are illustrated under the indeclinable situation of cover plate and cylinder (3) point of contact, change cover plate gagger (1) width, the correspondence situation of change of on average spacing.From the variation of four curves as can be seen, no matter which kind of cover plate, cover plate gagger (1) is when the width 30mm left and right sides, and it is preferable on average to space, and reduces width again, the curve trend is mild, on average spacing, it is very little to descend, and cover plate gagger (1) is when width is too narrow, and it is very narrow that flat-clothing (2) also will become, cover plate dial load can be increased like this, branch comb quality can be reduced on the contrary.Therefore, cover plate gagger (1) width that the utility model is selected is 30mm, and planting the pin width is 20mm, and carding machine revolving flats sum increases to 116, the work cover plate increases to 44, it is 2320mm that flat-clothing (2) is planted the pin overall width, has reduced 12mm than common cover, but both work cover plate to plant the pin width identical, all be 880mm, both saved and planted needle material, the load of needle point does not change again fully, and this also is to improve the essential condition of dividing the comb quality.

For implementing main equipment and the spare part that the utility model must be supporting:

1, blind flange card clothing;

2, cover plate Chain link for chain grate (cover plate chain and other part need not changed);

3, cover plate changes wheels (the new making);

4, cover plate changes wheels strut (the new making);

5, stay nut (standard component boring);

6, cover plate drive sprocket (the new making);

7, cover plate transmission pallet (the new making);

8, nut pin (standard component);

9, clad plate card clothing groove (the new making).

In necessary accessories and spare part, except that flat-clothing need card clothing factory manufactured specially, all the other accessories were all very simple.

The utility model compared with prior art has many advantages and good effect:

1, in the situation that does not increase cover plate dial load, strong purpose of dividing comb has realized tightly spacing.

2, the change of cover plate and position, cylinder point of contact has the effect of facet cover plate, is better than again the facet cover plate.

3, cover plate and the cylinder workspace equal in length after the improvement divides the comb gross area constant, can not affect adjacent and the installations holding parts, and plant transformation easy to use and frame manufactory adopt, small investment, instant effect.

4, especially adaptation matches with combing machine and rotor spinning machine, is conducive to improve output and quality.

5, cover plate size reduction is saved material, alleviates parts wear, increases the service life. The cover plate body is closer to equilateral triangle, thereby more firm.

6, the spatial operation area strengthens, and is convenient to workman's operation, proofreaies and correct and space.

7, avoided traditional correction position of spacing, can because of card wire heel end easily random pin cause artificial amplification to space, reduces to divide the phenomenon generation of comb quality.
