Description
Technical field
The present invention is a kind of color replacing mechanism, and particularly a kind of color replacing mechanism of embroidery machine needle line color, belong to the weaving field of mechanisms.
Background technology
Color replacing mechanism in embroidery machine of the prior art reaches the colour changing requirement by colour changing cam and common electric machine, due to the manufacturing deficiency of colour changing cam, makes it in the colour changing process, colour changing occurs not in place, reaches the situations such as colour changing screens, causes inefficiency.
Summary of the invention
The present invention solves the deficiencies in the prior art, provides a kind of colour changing fast and the color replacing mechanism that is used for embroidery machine of accurate positioning.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
a kind of color replacing mechanism for embroidery machine, comprise head, the side of described head is provided with needle bar frame, described needle bar frame is slidably connected by middle guide and lower guideway mutually with head, described needle bar frame is provided with shank, described head is provided with screw axis mechanism and grating encoder, described screw axis mechanism comprises screw axis, motor housing, stator, air-core armature, mother nut, bearing and rotor copper bush, be provided with the rotor copper bush in described motor housing, be fixed with air-core armature on described rotor copper bush, be provided with mother nut in described air-core armature, rotor copper bush and mother nut are crossed in described screw axis cross-under, described air-core armature is provided with the stator that fixes with it outward, the both sides of described air-core armature are respectively equipped with bearing, described bearing holder (housing, cover) is outside the rotor copper bush, described screw axis and needle bar frame fix, described grating encoder comprises grating disc, grating seat and photoelectricity generation receiver, and described grating seat is fixed on air-core armature, is provided with grating disc and photoelectricity generation receiver in described grating seat.
Being provided with some shanks in needle bar frame, is the line of different colours on shank, and color replacing mechanism is exactly mainly to come as required to carry out fast colour changing.
Screw axis mechanism, hollow turns under the drive of the rotary magnetic field force of stator, carry out rotational motion, be embedded with mother nut in the middle of air-core armature, mother nut rotates together with air-core armature, and screw axis two has been fixed on the screw mandrel frame, can not rotate, therefore, screw axis moving linearly under the effect of mother nut revolving force; Exist the gap between mother nut and screw axis, for eliminating this gap, right side at motor, secondary nut and spring are housed on air-core armature, under the effect of pressing force of the spring, produce a thrust in opposite directions between mother nut and secondary nut, thereby the gap of having eliminated between screw axis and mother nut has reached the purpose that gapless is rotated.The screw axis straight-line displacement is not rotated, and makes transmission more steady.Screw axis Linear transmission gapless makes transmission more accurate.Motor is controlled by computer automation, the deviation in the compensation colour changing, and colour changing is more accurate.
Grating encoder, grating seat are fixedly mounted on air-core armature, rotate together with air-core armature, and grating disc is arranged on grating seat, are carved with lenticular lenses on grating disc, and photoelectricity generation receiver is obtained rotation information by emission and the infrared light that receives lenticular lenses.
As preferably, described middle guide comprises guide rail coaster body, left socle, right support, circulating ball and correction guide rail, one end of described guide rail coaster body is provided with left socle, the other end of described guide rail coaster body is provided with right support, on described guide rail coaster body, cover has the correction guide rail, described correction guide rail slides on guide rail coaster body by circulating ball, and described correction guide rail is provided with the arc gap groove, and described arc gap groove is corresponding with shank.
To revise guide rail is fixed on head, guide rail coaster body is fixed on needle bar frame, needle bar frame is made horizontal rectilinear motion under the guide effect of revising especially big arc guide rail, guarantee that needle bar frame in precision and the load of horizontal straight line, requires line slideway to move agile undamped, and on existing head basis, needle bar frame moves to right-hand member from left end, keep not modification of linearity, but in fact because the gravity that carries has larger distortion, thereby the mobile accuracy of needle bar frame affected.
In order to overcome the above problems, we are to its stressed analysis, design the special shape that affects transmission accuracy because of stress deformation, this shape is that guide rail is revised, and makes the orthodrome shape, arc radius is different according to the pin number of needle bar frame, its size varies in weight to be out of shape and does not wait, and calculates the gained radius, and its scope is between R10m-100m, thereby after making the guide rail distortion, reach the linear precision of original setting.
Circulating ball makes slip more level and smooth light and handy.Especially big arc radius correction guide rail has the modification compensate function.Lengthen slide mass length, make carrying stronger.
As preferably, described guide rail coaster body fixes by left socle and right support and needle bar frame, and described correction guide rail and head fix.
As preferably, described arc gap groove comprises orthodrome gap slot and small arc-shaped gap slot, the top of described orthodrome gap slot is the small arc-shaped gap slot, described orthodrome gap slot and small arc-shaped gap slot are connected, the radius of described orthodrome gap slot is greater than the radius of small arc-shaped gap slot, and the sidewall of described orthodrome gap slot extends downward with guide rail coaster body and contacts.
As preferably, described rotor copper bush is outward extended with pullover, describedly is provided with secondary nut in pullover, and on described rotor copper bush, cover has spring, and described spring is by pullover and bearing crimping mutually.
As preferably, described bearing is located on bearing block, and described grating disc is enclosed within outside the rotor copper bush.
As preferably, described motor housing comprises front casing and rear casing, and described front casing and rear casing match fixing, described screw axis and needle bar frame bolt.
Therefore, the color replacing mechanism for embroidery machine provided by the invention, simple in structure, the colour changing accurate positioning is steady, and transmission is accurate, increases work efficiency.
