The utility model relates to an executing device for a monorail lower hook motion mechanism of a netting machine. The executing device comprises a lower hook assembly mechanism, a left-and-right guide rail for supporting the lower hook assembly mechanism, a front-and-back driving mechanism for enabling the lower hook assembly mechanism to perform front-and-back reciprocating motion along the guide rail and an up-and-down rotation driving mechanism for enabling the guide rail to perform up-and-down oscillation, wherein the guide rail meets the following requirement: when a lower hook moves to the corner where unweaving is performed in a shuttle, the guide rail is bent by 12-18 degrees in the position of the guide rail of the lower hook assembly mechanism at the time. According to the executing device disclosed by the utility model, by arranging a bent part at the tail part of the guide rail, when the unweaving is performed, the motion trajectory of the lower hook assembly mechanism can be bent due to the bending of the guide rail and can perform obliquely downward motion to smoothly complete the unweaving, so that the executing device disclosed by the utility model can greatly improve unweaving efficiency and quality in comparison with a traditional unweaving form.
Description
Technical field
The utility model relates to hook motion actuating unit under a kind of netting machine monorail, belongs to the netting machine technical field.
Background technology
The lower hook motion actuating unit of existing netting machine is comprised of following mechanism: front and back cam rocker arm mechanism, quiet moving lead mechanism, lower hook assembly mechanism.In the prior art, the situation of these four mechanisms is that cam rocker arm mechanism is that camshaft bearing assembly, rocking bar, kinematic link form up and down up and down, the bearing assembly that fixedly is equipped with of fork one end embeds up and down in the cam, rocking bar middle part activity is contained on the lining, the rear end of rocking bar is hinged with transmission connecting rod one end, and the kinematic link other end is hinged with moving guide rail.Promote up and down rocking bar during cam drive and swing up and down, make by kinematic link to be bearing in that the lower total journey of hook swings up and down in the moving guide rail.
There is following shortcoming in this motion: cam base circle is little, the stressed large easily damage of bearing assembly, and movement velocity is slow, and efficient is low, and lower hook breaks off relations and easily hinders line, and the net tablet quality is poor.The total journey two supports of lower hook on quiet moving guide rail, swing arm swing before and after promoting when the front and back cam rotates, by kinematic link make the total journey of lower hook on quiet guide rail in horizontal direction before and after back and forth movement.The shortcoming of this mechanism is: because to be subjected to structural limitations, shuttle shape can only be boat-shaped.Drum in the shuttle can't become greatly, and wire containing is few, the workman changes that the drum number of times is frequent, labour intensity is large, change drum often, artificial knot is many, the net tablet quality is also poor.This structure causes the total Cheng Hangcheng length of lower hook, line is slow excessively, speed is slow.
The patent No. is 2007200334671 drive units that a kind of bottom hook frame in net knitting machine is provided for this reason, and it is done and seesaw and move up and down by driving lower hook housing, can make netting machine select the larger arc back of the body formula shuttle of line capacity, increases work efficiency.
But also there is following defective in the said structure form: 1) because when lower hook off-line, because the existence of version makes hyposulculus keep original movement locus, do not form along the oblique lower movement tendency of shuttle, off-line efficient and off-line quality have been affected, strengthened operating personnel's workload, remained to be further improved; 2) lower hook assembly mechanism does not have guide supporting, and the rocking bar support near both sides in lower hook assembly mechanism reciprocating motion process, causes the damage of the parts such as spring bearing so easily, brings adverse effect to production.
The utility model content
The utility model is for defects, and purpose is to provide hook motion actuating unit under a kind of netting machine monorail that can increase substantially off-line efficient.
The technical solution adopted in the utility model is for this reason: the utility model comprises lower hook assembly mechanism, supports the left and right guide rail of lower hook assembly mechanism, and make lower hook assembly mechanism along the front and back driving mechanism of guide rail front and back back and forth movement, the up and down rotating drive mechanism that each guide rail is swung up and down, it is characterized in that, described guide rail satisfies following requirement, when hook moves to the corner of off-line place in the shuttle instantly, corresponding this at present the hook assembly mechanism bending of one 12 o-18 o is arranged at the position at guide rail place guide rail.
Described front and back driving mechanism: comprise that the lower end is fixed on the swing arm that forms moving fulcrum on the supporting seat, cam disc before and after the middle part of swing arm connects by bearing, described bearing is arranged in the cam dish type groove of front and back, the upper end of swing arm connects the front-rear linkage that drives lower hook housing motion by intermediate connecting rod, is provided with lower hook on the described lower hook housing.
Described up and down rotating drive mechanism: be a quadric chain, the bearing about wherein the drive end of quadric chain is embedded in by in the cam dish type groove is by up and down cam disc driving.
Described lower hook assembly mechanism: comprise hook under the n root, hook is fixed on the lower hook housing under the n root, the hinged m root movable rod suspension bracket in lower hook housing upper end, m root movable rod suspension bracket connects by a travelling cradle pipe, on fixed axis, fixed axis is movably connected on the upper beam by bearing the travelling cradle pipe by rod hinge connection.
The utility model has the advantages that: 1) the utility model is by arranging a bending part at the guide rail afterbody, its objective is when off-line, because the bending of guide rail, make lower hook assembly mechanism movement locus that bending occur thereupon, make its oblique lower motion to finish smoothly off-line, so the utility model is compared traditional off-line form, its off-line efficient and quality all increase substantially; 2) longer because of lower hook assembly length, in order to keep its each synchronized movement, make it in motion process, not produce inclination, improve its rigidity, the utility model addresses the above problem by the connection of a suspension bracket pipe, so that lower its rigidity of hook assembly of the present utility model improves greatly, each one can keep good synchronism.
