There is the energy-conservation lower crochet hook motion of knot fishing net machine
Technical field
The present invention relates to a kind of energy-conservation lower crochet hook motion of knot fishing net machine that has, belong to aquatic products articles for use technical field.
Background technology
Reticulated is divided into be had junction type and without junction type, is applicable to respectively different use occasions.If claimed structure is more stable, as net, used for aquiculture net cage etc. for fishing, general use has junction type reticulated.In architectural engineering with safety net, other occasion with sunshade net etc., generally adopt knotless net shape fabric.Knotless net shape fabric generally weaves by few guide bar warp knitting machine, has knot reticulated general using to have knot fishing net machine to weave.In order to realize, be woven with knot reticulated, in having junction type fishing net machine, the motion of lower crochet hook is one of main movement of complete machine, and its effect is knitmesh warp to be tempted to shuttle box rear portion from rising to the bait, and send warp downwards.
And existing to have the key operations of latch needle mechanism under knot fishing net machine be to be mentioned from top to bottom, fallen by the vertical rod of back, the impetus of action is at back, and course of work middle machine body is unstable, for improving its stability, must increase fuselage weight, make machine become heavy, not only power consumption is large, and installation is inconvenient, investment is large, and easily cause warp uneven, online occur large ommatidium, and the effective speed of complete machine is slow, fault is many, yield poorly, has had a strong impact on the serviceability of complete machine.

Of the present invention have a knot fishing net machine energy-conservation lower crochet hook motion, and the course of work is as follows:
Axle (A
0) by motor, driven, on it, be fixed with driving gear 1, drive the driven gear 2-1 being engaged with to rotate.On the wheel body of driven gear 2-1, be processed with grooved cam, wherein, 2-2 is grooved cam outer contour, and 2-3 is grooved cam inner outline.The first roller 3-2 is placed in grooved cam, when grooved cam rotates with driven gear 2-1, drives the first oscillating follower 3-1 around the first fixed pivot C
0point reciprocally swinging.
The first oscillating follower 3-1, first connecting rod 4-1, the second roller 4-2 and fixed guide frame 11 have formed swing slide block mechanism, and first connecting rod 4-1 is by the second pin joint C on the first oscillating follower 3-1
2hinged with it, the other end of first connecting rod 4-1 is hinged at the 3rd pin joint D and the second roller 4-2 center, the second roller 4-2 is placed in fixed guide frame 11, and fixed guide frame 11 maintains static, so, by driving gear 1, driven gear 2-1, grooved cam, the first oscillating follower 3-1, first connecting rod 4-1 and the second roller 4-2, be converted to the second roller 4-2 by the rotation of motor and as reciprocating linear, move fixed guide frame 11 is interior.The central point of the second roller 4-2 is hinged at the 3rd pin joint D with lower crochet hook needle-bar 8-1 again, and therefore, the reciprocating linear transverse motion of the second roller 4-2 in fixed guide frame 11, also makes lower crochet hook needle-bar 8-1 make straight line transverse motion along fixed guide frame 11.
Oscillating cam 2-4 and driven gear 2-1 are fixedly mounted on same axis B simultaneously
0upper, driven gear 2-1, grooved cam and oscillating cam 2-4 rotate together with as a whole, but have phase angle relationship between oscillating cam 2-4 and grooved cam.Oscillating cam 2-4 drives the second oscillating follower 5-1 around the second fixed pivot E
0spot wobble, in order to reduce friction, the second oscillating follower 5-1 is at the 4th pin joint E
1point is provided with three rollers 5-2, and the second oscillating follower 5-1 is at the second fixed pivot E
0point opposite side be the first fork 5-3, the second oscillating follower 5-1 be an integral body with the first fork 5-3 together with around the second fixed pivot E
0spot wobble.The first fork 5-3 and second connecting rod 6 are at the 5th pin joint E
2hinged, second connecting rod 6 and the second fork 7 are hinged at the 6th pin joint F.By the first fork 5-3, second connecting rod 6, the second fork 7 and the second fixed pivot (E

0.The first fork 5-3 swings together with the second oscillating follower 5-1, and the second fork 7 is swung.The end of the second fork 7 has radial slot, is called sheave radial slot.Upper the 7th pin joint G of lower crochet hook needle-bar 8-1 and the 4th roller 8-2 center are hinged, the 4th roller 8-2 is placed in the sheave radial slot of the second fork 7, when the second fork 7 swings, lower crochet hook needle-bar 8-1 swings thereupon together, thereby has realized the oscillating motion requirement of time crochet hook.Generally, the width of the sheave radial slot of the second fork 7 is identical with the width of fixed guide frame 11, and the diameter of the second roller 4-2 and the 4th roller 8-2 is also identical.When lower crochet hook needle-bar 8-1 makes straight line transverse motion, the sheave radial slot of the second fork 7 overlaps with the center line of fixed guide frame 11, when crochet hook needle-bar 8-1 straight line transverse motion arrives in Fig. 2 rightmost side extreme position instantly, lower crochet hook needle-bar 8-1 straight line transverse motion stops, lower crochet hook needle-bar 8-1 to lower swing, breaks off relations the warp on lower crochet hook with the second fork 7.Obviously, in lower crochet hook needle-bar 8-1 reciprocating linear transverse motion process, the second fork 7 keeps transfixions, and the sheave radial slot of the second fork 7 and the center line of fixed guide frame 11 always keep overlapping.Suppose that the second roller 4-2 keeps maintaining static, by the second fork 7 and lower crochet hook needle-bar 8-1, form Geneva mechanism, lower crochet hook needle-bar 8-1 is swung.
On lower crochet hook needle-bar 8-1, be installed with lower crochet hook 8-3, on whole lower crochet hook needle-bar 8-1, along machine-wide direction, according to Density, require to determine the installation interval between pin and pin, i.e. needle gage.
Because lower crochet hook needle-bar 8-1 only need to have two freedoms of motion, and lower crochet hook needle-bar 8-1 integral body is done plane motion, altogether by 3 freedoms of motion, so, must further limit its one degree of freedom, structurally take an additional II level bar group HJJ who is formed by third connecting rod 9 and the 3rd fork 10
0, as shown in Figure 2.Third connecting rod 9 is hinged at the 8th pin joint H with lower crochet hook needle-bar 8-1, and third connecting rod 9 and the 3rd fork 10 are hinged at the 9th pin joint J, and the 3rd fork 10 is around the 4th fixed pivot J
