Description

A kind of sinker of Computerized flat knitting machine

Technical field

This utility model relates to the sinker of flat machine technical field, specifically Computerized flat knitting machine.

Background technology

Sinker is the important component part of Computerized flat knitting machine, and effect is to block yarn to make it non-rising, Yi Jixiang Lower pressure fabric thus play certain pushing effect, assisted braid movement.During work, rising of sinker Sheet bell is by a triangle orbits controlling on head, and triangle makes sinker swing, and grips when fabric rises and knits Thing, auxiliary is moved back circle, or the rollback when knitting needle declines, is prepared for knocking over.Existing sinker as shown in Figure 4, Defect is: 1, amplitude of fluctuation is limited, and yarn may float, and yarn easily with knitting needle and needle-bar generation Friction, causes yarn to fluff, affects product quality；2, the spring bottom sinker is flat spring C1, sheet bullet The welded top of spring is in sinker side, and the force direction of flat spring and sinker be not in a plane, long After time uses, the force application angle between sinker and flat spring easily produces change, and one is to cause sinker Action levels of precision reduce, two is to shorten the service life causing flat spring, above-mentioned wait improvement.

Utility model content

Technical problem to be solved in the utility model is the deficiency overcoming above-mentioned background technology, it is provided that Yi Zhong electricity The improvement of the sinker of brain straight-bar machines, the sinker after improvement can swing in a big way, reduces on yarn Floating, and can effectively prevent yarn and knitting needle and needle-bar friction, improve service life, it is ensured that product Quality.

This utility model have employed techniques below scheme: the sinker of a kind of Computerized flat knitting machine, including being hinged on pin Sinker body on the inserted sheet of bed and be fixed on the spring of sinker body bottom portion, it is characterised in that: heavy The downside of the press section of fall sheet body is provided with a gear tongue.

As preferably, the distance risen between sheet bell and pin joint of sinker body, equal to press section with hinged The 40～60% of the spacing of point；Line between press section and pin joint, and rise between sheet bell and pin joint The angle of line is 60～90 degree.

As preferably, the base of both sides, described sinker body articulated section offers the first recess and respectively Two recesses, described spring is shaped with the first bending section and second bending section of protrusion, and the first bending section embeds first In recess, the second bending section embeds interior and with the second recess the profile of the second recess and adapts, and articulated section embeds Concave part between the first bending section and the second bending section；The end of the second bending section stretches out and supports Lean against on the tooth form piece of needle-bar.

As preferably, a length of the 1～8cm of described gear tongue.

The beneficial effects of the utility model are: in this utility model, and sinker body is provided with gear tongue, weaves In journey, yarn is stopped by gear tongue, will not rub with knitting needle and needle-bar, it is to avoid fluffiness occurs； And, the distance risen between sheet bell and pin joint (can play less than the distance between press section and pin joint Leverage) and angle be acute angle, when head to rise sheet bell force time, the action of press section can be exaggerated, Reduce the phenomenon that yarn floats, improve product quality；It addition, this utility model changes spring into continuous bend Flat spring, spring is resisted against base rather than the side of sinker body, the force direction of spring and sedimentation Sheet always can be in a plane, and force application angle will not produce change, can be effectively improved the dynamic of sinker Make precision and service life.

Detailed description of the invention

Below in conjunction with Figure of description, the utility model is described in further detail, but this utility model not office It is limited to following example.

As shown in Figure 1 and Figure 2, the sinker of Computerized flat knitting machine described in the utility model, including sinker body A1 and spring A2, sinker body uses metal material to make (such as iron plate, steel disc), this sinker Body is hinged on the inserted sheet of needle-bar 6 (mounting means is similar with existing sinker), and a sheet of sinker Bell 1 is driven by the head 5 of Computerized flat knitting machine.

In this utility model, the downside of the press section 3 of sinker body is provided with a gear tongue 4, and (press section has The coupler body of held loop), gear tongue 4 and this body by integral forming of sinker, the length of gear tongue is according to the rule of sinker Lattice determine, it is recommended that a length of 1～8cm (the most a length of 3cm or 4cm).In order to reduce frictional force, gear Curved grinding process can be made in the edge of tongue and yarn contacts.

Distance A risen between sheet bell and pin joint 2 of sinker body, equal between press section and pin joint The 40～60% of distance B；Line between press section and pin joint, and the line risen between sheet bell and pin joint Angle β be 60～90 degree.When head is to when playing sheet bell force, and the action of press section can be exaggerated, and reduces The phenomenon that yarn floats, improves product quality.

As shown in Fig. 3-1 and 3-2, described spring is formed through bending several times by steel wire or steel disc, thus There is elasticity.It is recessed that described sinker body A1 offers first on the base of A1-3 both sides, articulated section respectively Mouth A1-1 and the second recess A1-2, described spring is shaped with the first bending section A2-1 and second bending section of protrusion A2-2.First bending section embeds in the first recess, and, more than width, (degree of depth is the degree of depth of the first recess 2 to 3 times of width), the first bending section keeps the potential energy externally opened, thus is clamped on first after insertion In recess, also function to the effect of fixing spring.Second bending section embeds in the second recess, and articulated section is embedded into Concave part A2-4 between first bending section and the second bending section；The end A2-3 of the second bending section is to extension Stretch and be resisted against on the tooth form piece of needle-bar.When sinker swings, spring applies active force to sinker body.

Finally it should be noted that listed above is only specific embodiment of the utility model.Obviously, This utility model is not limited to above example, it is also possible to have many variations.Those of ordinary skill in the art's energy The all deformation directly derived from this utility model disclosure or associate, are all considered as this practicality Novel protection domain.
