Abstract
Disclosed is a computerized electromagnetic weft-selecting device, the aluminum positioning plate of which is evenly distributed with electromagnets aligned radially. A guiding rack is provided between the aluminum positioning plate and an aluminum covering plate; the inside of the electromagnet is provided with a coil and a stationary iron core; the stationary iron core is fixed on the end part of the electromagnet body; one end of a movable iron core inserts the coil arranged inside the electromagnet body to connect with weft-feeding needles; the other end of the weft-feeding needle inserts the guiding groove of the guiding rack. The computerized electromagnetic weft-selecting device of the utility model is written with a flower-shaped program by a flower-shaped storage chip and then is triggered and output by a hall sensor at the specified corner of a loom, and the flower-shaped storage chip is arranged inside a special-use computer controller, which controls the electromagnet to directly drive a weft-selecting needle; the electromagnet is aligned radially; the plurality of weft-feeding needles are sent at one point, and the weft-feeding needles extend and contract at the different guiding grooves of one same guiding rack, so as to avoid the mutual interference; the weft-selecting needle can stop at the working position when does not change weft under the control of the high and low voltage of the computer, so as to reduce the friction of a weft yarn. The electromagnet has quick reaction rate, and thus can adapt to the high-speed requirement of looms.
Description
Technical field
The utility model relates to a kind of computer electromagnetism weft-selecting mechanism, belongs to the weaving and knitting preparation field, mainly is applicable to the weft color selection of shuttleless loom such as Rapier looms gripper shuttle loom.
Background technology
Shuttleless loom is Rapier looms for example, and different weft yarns is delivered to the operating position, is sent in the shed open by the sword head, needs to adopt weft-selecting mechanism.International and domestic weft-selecting mechanism such as SMIT, SOMET weft-selecting mechanism, though useful computer control, but mechanical mechanism is more complicated all, and send moving up and down that the latitude bar do not stop, when not changing weft yarn, send the latitude bar also will swing up and down, increased the friction of weft yarn, improved end breakage rate, and arrange difficulty and the fault rate that has also increased the accent machine before and after sending the latitude bar, therefore a lot of users like using the machinery by the pulling of dobbies harness threading arm to select latitude, but have taken the harness threading arm of dobbies like this, have weakened the function of multi-arm.
Summary of the invention
The purpose of this utility model just provides a kind of simple in structure, with low cost, long service life, computer electromagnetism weft-selecting mechanism that reliability is high.
Computer electromagnetism weft-selecting mechanism of the present utility model is a uniform electromagnet on location-plate, the electromagnet arranged radially, cover plate is set on the electromagnet, establish guide bracket between location-plate and patch ends, electromagnet comprises electromagnet, be provided with coil in the electromagnet, secured core, the secured core of hollow is fixed on the end of electromagnet, be cast into copper sheathing in the coil rack, copper sheathing one end is located by secured core, the other end and electromagnet end are fixed, one end of movable core is inserted in the interior coil of electromagnet, its end links to each other with sending the latitude pin, send the other end of latitude pin pass secured core be inserted in leading of guide bracket poor in, leading the poor angle of inclination that has on the guide bracket, this inclination angle design can avoid selecting the mutual interference of latitude pin phase, secured core one end on the electromagnet end is fixed with nut, location one extension spring on the nut, and the other end of extension spring is fixed on and send on the latitude pin.
Computer electromagnetism weft-selecting mechanism of the present utility model triggers output at the regulation corner of loom by Hall element by the colored type program that flower type storaging chip in the special purpose computer controller writes, the control electromagnet, electromagnet directly drives and selects the latitude pin, because electromagnet becomes arranged radially, many are sent the latitude pin to send in a bit (center of circle), it is flexible to send the latitude pin to lead in poor in the difference of same guide bracket, has avoided mutual interference.Under the control of computer high-low pressure, select the latitude pin when not changing latitude, can stop in the operating position, reduce the weft yarn friction, the effect of screwed pipe power simultaneously, make the move distance of movable core reach 40 millimeters (or longer), movable core moves in copper sheathing, has high abrasion long-life characteristics, the reaction speed of this kind electromagnet is fast, can adapt to loom requirement at a high speed.
Computer electromagnetism weft-selecting mechanism of the present utility model is owing to adopt said structure, makes it compared with prior art have simple in structure, with low cost, long service life, high reliability features.
