Abstract
The invention discloses a device with two upper openings and a lower opening. The device is formed by connecting a rotary disk rotating guide rod mechanism and four connecting rod mechanisms in series. The rotary disk guide rod mechanism comprises a rotary disk which is provided with two sliding grooves, two sliders which can slide in the sliding grooves are arranged in the two sliding grooves respectively, the rotary disk rotates around the center thereof, the two sliders are respectively hinged with a guide rod, the guide rod rotates around a second center, and the rotary disk and the second center are fixed to a frame respectively. Each of the four connecting rod mechanisms comprises a crank hinged to the second center, the cranks are hinged to a connecting rod and a swinging rod sequentially, and the swinging rods are hinged to the frame. Starting from a high-speed angle of a loom, in order to adapt to high revolution speed of the existing air-jet loom of 900-1000rpm, cam mechanisms are replaced by the connecting rod mechanisms, and accordingly the requirement for weaving process is met while vibration sources such as a cam and a cam rotor is also eliminated and other parts of the air-jet loom are prevented from damage.
Description
Technical field
The invention belongs to loom field, relate to a kind of flat shedding mechanism, relate to specifically shedding motion once on a kind of two.
Background technology
Air-jet loom shedding mechanism majority cam shedding mechanism, with the cam shedding mechanism of higher pair, the fine technological requirement that realizes integrated box movement of energy, but at a high speed inadaptable.Cam is responsive especially to manufacturing the precision of processing, and cam will adapt to 600 revs/min of above high speeds, and the necessary high accuracy of cam, manufactures high accuracy cam difficult especially.Once cam precision does not reach the accuracy of manufacture, do not meet the demands, just produce destructive dynamic force, especially conjugate cam, has become the great resistance that shedding mechanism develops.
Use the shedding mechanism of Tape movement pair to substitute cam mechanism, in design some difficult point.Every page of heald frame has a set of independently cam drive mechanism, every page of corresponding a slice cam of heald frame.For fabric tissue, cam has all styles of, as plain weave, twill etc., as on two once, two inferior on two times, two on one, the cam of various shapes can meet woven kinds of processes requirement.With linkage, substitute cam, a difficult point is that each cam must have special linkage to substitute.
The flat shedding mechanism of Tape movement pair is applied on air-jet loom.Shedding mechanism completes the alternately lifting of levels warp thread, a loom rotating speed 100-200 rev/min in the past, and after having improved the cam accuracy of manufacture, the speed of cam shedding mechanism is applicable to be still limited in below 600 revs/min.The rotating speed 900-1000 rev/min of present air-jet loom, loom speed is high, uses cam shedding mechanism but to bring damage and impulsive force, and cam and cam follower become the vibration source of loom, become the root of various another parts damages.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides shedding motion once on a kind of two, with linkage, substitute cam mechanism, be well positioned to meet the technological requirement of integrated box movement.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
Shedding motion once on two, is composed in series by dial rotation guide-bar mechanism and quadric chain;
Described dial rotation guide-bar mechanism comprises a rotating disk, described rotating disk is provided with the first chute and the second chute, in described the first chute and described the second chute, be respectively equipped with the first slide block and second slide block that can slide in its groove, described rotating disk rotates around center of turntable, described the first slide block and described the second slide block are hinged with guide rod respectively, described guide rod is around the second center rotating, and described center of turntable and described the second center are individually fixed in frame;
Described quadric chain comprises and is articulated with bicentric crank, and described crank is articulated linkage and rocking bar successively, and described rocking bar hinged hinge is in frame.
Further, described the first chute is mutually vertical with described the second chute.
Further, the first support arm of the distance between described center of turntable and described the second center and described guide rod and the second support arm is equal in length.
Compared with prior art, the present invention has following beneficial effect:
The present invention is from weaving machine high-speed angle, in order to adapt to the high rotating speed of present air-jet loom 900-1000 rev/min, linkage is replaced to cam mechanism, when meeting weaving process requirement, also eliminate the such vibration source of cam and cam follower, avoided the damage of other parts of air-jet loom.
