The mechanism that in described driving, crochet hook (7-3) swings, generally be arranged on the both sides in machine-wide direction, and have that two groups of identical mechanisms are parallel to each other to be synchronized with the movement respectively, in common driving, crochet hook needle-bar 7-2 swings, described upper crochet hook 7-3 is provided with many pieces according to the fabric width of institute's making fishing net, order is arranged on crochet hook needle-bar 7-2, and installs side by side along machine length direction.
Of the present invention have crochet hook swing mechanism on knot fishing net machine, and the course of work is as follows:
Axle A0 is driven by motor, it is fixed with driving gear 1, drives the driven gear 2 be engaged with to rotate.The wheel body of driven gear 2 is processed with grooved cam 3, and wherein, 3-1 is outer contour, and 3-2 is inner outline.Driving gear 1 to be slowed down rear drive through V belt translation by motor, grooved cam 3(outer contour 3-1 and inner outline 3-2) structure on driven gear 2 wheel body, the shape fixed pivot together on main shaft B0 in aggregates rotates.
The groove that 3-1 and 3-2 that second roller 6 is placed in grooved cam 3 is formed, the diameter of the second roller 6 is identical with the width of groove, and it is hinged that the center of the second roller 6 and guide rod 5 pass through revolute pair at C pin joint.When grooved cam 3 rotates with driven gear 2, driving cam means driven member and guide rod 5 move linearly.Because the second roller 6 and guide rod 5 are hinged by revolute pair at C point, so, be rolling friction between the inside and outside outline line (3-1 and 3-2) of the second roller 6 and grooved cam 3.Because the first roller 4 empty set is at main shaft B
0on, do asynchronous rotation with main shaft, therefore when guide rod 5 up and down reciprocatingly moves linearly, the first roller 4 is also rolling friction with the frame-shaped construction (5-1) of guide rod 5.
Guide rod 5 has frame-shaped construction (5-1) in the middle of its two-end-point, the width of frame-shaped construction (5-1) is identical with the diameter of the first roller 4, during installation, the first roller 4 is placed in the frame-shaped construction (5-1) of guide rod 5, and also namely the frame-shaped construction (5-1) of guide rod 5 is enclosed within the first roller 4.The center empty set of the first roller 4 is arranged on main shaft B0, i.e. the asynchronous rotation with main shaft.Such structure makes guide rod 5 one aspect can swing around B0 axle along with the first roller 4, meanwhile, makes again guide rod 5 up and down reciprocatingly be moved linearly by B0 point.One end of guide rod 5 is connected with revolute pair at D1 point with side link 7-1, and side link 7-1 swings around upper crochet hook needle-bar swinging axle D0.When guide rod 5 moves as reciprocating linear under the driving of grooved cam 3, drive side link 7-1 reciprocally swinging.Side link 7-1 is fixedly mounted on crochet hook needle-bar swinging axle D0, and when side link 7-1 swings, upper crochet hook needle-bar swinging axle D0 swings thereupon.Side link 7-1 and upper crochet hook needle-bar 7-2 is an entirety, the fixed pivot spot wobble together on D0 axle.Upper crochet hook 7-3 is fixedly mounted on crochet hook needle-bar 7-2, and swings with upper crochet hook needle-bar 7-2 and side link 7-1.
