Description
Technical field
The present invention relates to the auxiliary mechanism of weaving loom warp harness motion, particularly relate to the electronic cutting mouth mechanism of a kind of Direct driver heald frame, belong to technical field of textile machine.
Background technology
Weaving loom warp harness motion is one of big basic motion of weaving loom five. Weaving loom opening mechanism has a variety of, and the complicated big flower-shape of weaving adopts jacquard weave opening mechanism, and little flower-shape of weaving adopts type dobby shedding mechanism, and the former produces senior fabric, and the latter produces conventional fabric. So being called as dobbies, because the warp of this kind of weaving loom is by the dynamic heald frame of mechanical pendulum arm straps, then is driven by heald frame and realize harness motion. Type dobby shedding mechanism consumption is maximum, and form has mechanical lever aperture, cam shedding different types of machines. Along with the development of electronic technology, electronic dobby machine occurred, electronic dobby machine is by computer input program, so that it may to produce the fabric of different flower-shapes, be the inexorable trend of textile manufacturing machine electronization.
But, existing electronic dobby machine, complex structure, in restriction heald frame 12 millimeters of spacing, too much part makes its thickness be restricted. Under the impact force action repeated at a high speed, it may also be useful to the life-span is restricted. China copied through the more than ten years, did not still realize production domesticization. The patent of invention that patent is ZL.201310751696.7 discloses one " electric cam " swing type dobbies, is a kind of technical scheme separately warding off path, which solves the problem that foreign country rotates electronic dobby machine complex structure. Along with the development of technology, in restriceted envelope, strength and the stroke of linear voice coil motor and electro-magnet do bigger and bigger. According to the principle that the machine design when content with funtion requires must be more simple more good, adopt the mode of Direct driver heald frame, it is achieved weaving loom warp harness motion, it should be the simplest, the warp opening machinery of most direct electron.
Realizing the ideal of Direct driver heald frame, first to be found a kind of electric driving force element, it can be manufactured in the space limited, volume is little, strength is enough big, and stroke must be over 120 millimeters (exceeding general weaving loom, the maximum open size of warp). Along with the development of art technology, at present, the electro-magnet of stroke more than 120 millimeters and linear voice coil motor has been produced. Possibility is brought like this to the Direct driver realizing heald frame. But the Direct driver realizing heald frame still needs to address the problem technically: one is adopt anything to connect structure to drive heald frame; Two is the resistance of motion how reducing and driving heald frame; Three is how to arrange to open electric driving force element in 12 millimeters of spacing.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, it is provided that a kind of compact construction, the electronic cutting mouth mechanism being convenient to the Direct driver heald frame driven.
