A kind of card wire replacing structure
Art
The present invention relates to textile machine apparatus field, especially, is a kind of for comb and parallel cotton fibers prior to spinning card wire replacing structure mechanically.
Background technology
Comb and parallel cotton fibers prior to spinning utilizes cover-plate type or roller type carding machine, by dial motion, is filament state little flock combing, removes impurity and not spinnable staple fibre further, fibers parallel is stretched, finally makes sliver dish and enter in bar cylinder.After Blowing-carding Unit processing, in lap or loose wool, fiber is many in loose cotton block, flock state, and contain the impurity of 40% ~ 50%, wherein most is tiny, that adhesiveness is stronger fiber impurity (as band fiber breaks seed, mote, soft seed epidermis, cotton knot etc.), so fibre bundle thoroughly must be resolved into single fiber, remove the fine impurities that remains in wherein, the composition fiber that makes respectively to distribute cotton is fully mixed under filament state, makes uniform sliver to meet the requirement of later process.
The topmost functional component of carding machine is card wire, in whole carding process, card wire is all in the friction of cotton fiber, its life-span and operating condition are directly connected to carding machine efficiency and carding quality, therefore just must change when card wire causes during certain wearing and tearing, when combing being carried out to the fiber of different cultivars simultaneously, the card wire of different size need being adjusted, therefore for putting forward the efficiency of carding machine, quick-replaceable must be carried out to the card wire on needle stand.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide a kind of card wire replacing structure, this card wire replacing structure can quick-replaceable card wire.
The technical solution adopted for the present invention to solve the technical problems is:
This card wire replacing structure comprises card wire and tilting magnetic sheet, the magnet matched with described magnetic sheet is provided with in the needle point of described card wire, the attraction of described magnetic sheet to described magnet is less than or equal to the gravity of described card wire, the Lower Half surface of described magnetic sheet is evenly equipped with the cell body to downward-extension, described cell body is arranged side by side and groove width is successively decreased downwards, the end of described cell body be provided with to match with described card wire needle point and the locating recesses of taper, the bottom of described locating recesses is provided with the second magnet attracting described card wire inner magnet.
As preferably, described locating recesses is flexibly connected with described magnetic sheet.
As preferably, the edge of described locating recesses is provided with the first electrode, the bottom of described locating recesses is provided with monitoring chamber non-contacting with the needle point top of described card wire, the second electrode is provided with in described monitoring chamber, described second magnet is electromagnet, described electromagnet quits work when described first electrode and the second electrode short circuit, and described card wire is made up of conductive material.
As preferably, the described card wire of different size is equal in weight, the profile of needle point varies in size.
The advantage of invention is:
Promote card wire and be placed on the first half of described magnetic sheet, because the attraction of described magnetic sheet to described magnet is less than or equal to the gravity of described card wire, therefore the effect that card wire is subject to inertia or gravity enters described cell body, card wire continues to slide into described locating recesses, and card wire is arranged in row and can be mounted on needle stand.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
In the present embodiment, consult Fig. 1 and Fig. 2, this card wire replacing structure comprises card wire 500 and tilting magnetic sheet 100, the magnet 510 matched with described magnetic sheet 100 is provided with in the needle point of described card wire 500, the attraction of described magnetic sheet 100 to described magnet 510 is less than or equal to the gravity of described card wire 500, the Lower Half surface of described magnetic sheet 100 is evenly equipped with the cell body 110 to downward-extension, described cell body 110 is arranged side by side and groove width is successively decreased downwards, the end of described cell body 110 be provided with to match with described card wire 500 needle point and the locating recesses 200 of taper, the bottom of described locating recesses 200 is provided with the second magnet 400 attracting described card wire 500 inner magnet 510.
Above-mentioned card wire replacing structure, described locating recesses 200 is flexibly connected with described magnetic sheet 100, changes different locating recesses 200 to adapt to different size card wire 500.
Above-mentioned card wire replacing structure, the edge of described locating recesses 200 is provided with the first electrode 310, the bottom of described locating recesses 200 is provided with monitoring chamber 330 non-contacting with the needle point top of described card wire 500, the second electrode 320 is provided with in described monitoring chamber 330, described second magnet 400 is electromagnet, described electromagnet quits work when described first electrode 310 and the second electrode 320 short circuit, described card wire 500 is made up of conductive material, when the card wire 500 selected is not the card wire needing specification, and the needle point profile of this card wire is when being less than the card wire needing specification, card wire needle point inserts described monitoring chamber 330, first electrode 310 and the second electrode 320 short circuit, second magnet 400 lost efficacy, not need the card wire of specification to drop.
Above-mentioned card wire replacing structure, the described card wire 500 of different size is equal in weight, the profile of needle point varies in size, when the card wire 500 selected is not the card wire needing specification, and the needle point profile of card wire is when being greater than the card wire needing specification, because card wire 500 cannot insert described locating recesses 200 completely, because the distance of magnet 510 with described second magnet 400 increases, cause the attraction of card wire not enough, card wire drops.
The mode of operation of above-mentioned card wire replacing structure:
Consult Fig. 1 and Fig. 3 and promote card wire 500 and the first half being placed on described magnetic sheet 100, because the attraction of described magnetic sheet 100 to described magnet 510 is less than or equal to the gravity of described card wire 500, therefore the effect that card wire 500 is subject to inertia or gravity enters described cell body 110, card wire 500 continues to slide into described locating recesses 200, and card wire 500 is arranged in row and can be mounted on needle stand.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
