Description

The sinker of knitting machine

The utility model relates to a kind of sinker of knitting machine.

Sinker is the aid of manufacturing yarn ring, the machine difference of complying with its application target and matching, and different designs is arranged, but existing this type of sinker can be divided into two classes haply:

(1) compress sinker: in the chute of its sinker ring surface of can packing into, utilize the protruding rail operation, reciprocating motion takes place, thereby generate the function of grasping fabric.General sinker structure is provided with belly 91 at sinker 90 front ends shown in Figure 14 and 15, be one to the nose 92 that protracts above belly 91, is recessed into to be a throat 93, the protruding upward one protruding pin 94 at the proximal end place again between belly 91 and nose 92.In Figure 15, then below belly 91, stretch out a guiding pin 95 forward.

The effect of compress sinker:

(1) when knitting needle rises, sinker slips into interior position, utilizes the compacting strength of nose to yarn interannular connection yarn, and old yarn ring can not risen with pin, in order to avoid cause floating of fabric;

(2) when knitting needle descends, sinker withdraws from outer position, utilizes the stop strength of belly to yarn interannular connection yarn, old yarn ring can not descended with pin, and can successfully break away from syringe needle; Simultaneously, the existence of this belly is obstructed the new yarn of being left behind by pin, is bent to ring.

(2) make the ring sinker: its installation and motion and aforementioned compress sinker are similar, but its effect then is: push away effect before the utilization, feeding the yarn that draws in nose the place ahead, on the shank that circumnutates, form the yarn ring, in order to the hook pulling process of knitting needle.Because this type of kind of making the ring sinker is extremely many, be to lift shown in the accompanying drawing 16 to explain for example, its basic structure and compress sinker are roughly the same, have structures such as belly 91, nose 92, throat 93 and protruding pin 94 equally, just in order to adapt to the demand of operating effect, be provided with two noses 92, and be formed with two throats 93.

Existing towel kind is extremely many, according to machine and the weave difference that different vendor adopted, and produces different products.Modern just general more general " Towel gasket formula decorative pattern plain weave FIGURED CLOTH " for example explains, the cloth cover decorative pattern of this kind fabric is to be assembled by the Towel gasket that long sedimentation ring forms to form.

This kind fabric utilizes the degree of advancement of change proboscis sinker during the system of knitting, so that: sinker enters leading position, and nose is hooked veil, forms a regular Towel gasket (as shown in figure 17); Sinker enters normal position, and nose can't hook veil, thereby makes it inweave in the cloth (as shown in figure 18, it weaves the style of finishing promptly as shown in Figure 19) in company with filling.

This type of Towel gasket formula FIGURED CLOTH also can partly impose cropping to its decorative pattern, so can become lint formula FIGURED CLOTH.

But analyzed as can be known with regard to this type of cloth cover structure, though its veil is fixed by the filling knotting, but when making lint formula FIGURED CLOTH carrying out cropping, its veil fixed effect through cropping is promptly tested, just with the structure view shown in Figure 19 it, if the veil at Towel gasket place is cut off, then its base portion only can be fixed by simple weaver's knot, promptly might deviate from case be subjected to external force, obviously still dislike not enough on its structural strength.

In addition, existing lint formula FIGURED CLOTH is to be undertaken by the sheet of cutting off that another sheet is arranged on the knitting machine when cutting off Towel gasket, and it often can't quite positively be cut off Towel gasket when operation, and can form faulty materials, this is again that existing knitting machine is not attained on structural design and improved part.

Main purpose of the present utility model is: a kind of sinker of knitting machine is provided, and makes the towel structure more strengthen, and can form the towel cloth of lint formula.

The purpose of this utility model is achieved through the following technical solutions, a kind of sinker of knitting machine is provided, its front end is the belly that protracts, the belly top is a nose, between belly and nose, be recessed throat, at sinker proximal end place protruding upward one protruding pin, below belly, stretch out a guiding pin again forward, wherein:

The nose of sinker is the shape of a bending, it has a nose that slightly lets droop, upper limb at this bending position is provided with the upwards protruding nose of boss again, and the inclined-plane that formation one is risen between nose and protruding nose, throat is provided with and is an arc-shaped slot again, be the protuberance of two arcs in this throat's lower edge setting, and form separation trough respectively and reverse groove in the front end of two protuberances.

In addition, also can one broken yarn portion be set at the terminal upper limb of nose.And, also can be provided with a upper flange protruding upward at the belly upper limb, the peak height of this upper flange is high than nose.

Advantage of the present utility model is, because the nose of sinker and the design of throat can make veil and filling form anti-package twice in knotting place, and make the towel structure more strengthen when veil form Towel gasket.Because veil is made ring when finishing, can the veil at Towel gasket place be cut off again, thereby form the towel cloth of lint formula by broken yarn portion.And, so can make veil more firmly be combined on the towel, can not be drawn out, thereby can provide quality more excellent towel cloth because of external force easily because the veil of knotting place is through twice anti-package.

Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing.

Figure 19 is general " Towel gasket formula decorative pattern plain weave FIGURED CLOTH " structural representation.

See also shown in Figure 1, it is sinker 10 planar structure schematic diagrames of the present utility model, wherein can see its basic structure and roughly the same existing, at sinker 10 front ends is the belly 11 that protracts, belly 11 tops are nose 12, be recessed throat 13 again between belly 11 and nose 12, the protruding upward one protruding pin 14 at the proximal end place stretches out a guiding pin 15 again forward below belly 11.

But can see belly 11 upper limbs of the present utility model in the drawings and be a upper flange 111 protruding upward, nose 12 is the shape of a bending, it has a nose that slightly lets droop 121, upper limb at this bending position is provided with the upwards protruding nose 122 of boss again, and form an inclined-plane that rises betwixt, at nose 12 terminal upper limbs one broken yarn portion 123 is set again, in addition throat 13 is provided with and is an arc-shaped slot, and be the protuberance of two arcs in these throat's 13 lower edge settings, and form separation trough 131 respectively and reverse groove 132 in the front end of two protuberances, this a part of structure is architectural feature of the present utility model place.

For ease of service behaviour of the present utility model is had more deep understanding, the special action schematic diagram of the utility model sinker 10 when weaving with Fig. 2～13 explains.When sinker 10 begins to advance as shown in Figure 2, can touch the rising ramp of 122 in nose 121 on the nose 12 and protruding nose by the veil 30 of feed (not shown) feeding, filling 31 then can abut in belly 11 upper limbs, and the opening of knitting needle 20 then just can be included veil 30 and filling 31 between pinhock and the needle latch in;

As sinker 10 move on (in figure left side move), 20 on knitting needle continues to move down, be subjected to sinker 10 noses 12 rising ramps and knitting needle 20 relativities that move down because of veil 30 this moment, abut in the inboard upper limb of pinhock and make it be tensioned state, filling 31 then is subjected to the sluggishness of separation trough 131 and abuts in the vertical place (as shown in Figure 3) of pinhock inboard.Even veil 30 all abuts in the inboard upper limb of pinhock with filling 31 when knitting needle 20 continues to descend, and filling 31 preceding (left side among the figure) veil 30 after.Then, because the reach that sinker 10 continues, and knitting needle 20 slightly rises, the vertical motion that makes veil 30 be positioned at nose 12 rising ramp sections slightly stagnate and its tight state slightly loose, but 31 of fillings are subjected to the traction of knitting needle 20 and break away from separation trough 131, and along separation trough 131 and reverse on the protuberance of 132 of grooves and move.At this moment, because filling 31 abuts in the friction that is produced when mobile on sinker 10 protuberances and reels, and with the friction guidance of 30 on the veil of reclining mutually, and make and make clockwise anti-package (veil 30 as shown in Fig. 5～Fig. 7 and filling 31 in knitting needle 20 pinhocks exchange front and back position) mutually at the veil 30 relative fillings 31 of knitting needle 20 pinhock inboards.

When position shown in Fig. 6 to Fig. 7, knitting needle 20 moves down once more, because filling 31 was positioned at separation trough 131 and reversed on the mild position of protuberance of 132 of grooves, so it is more loose state this moment.Veil 30 then between knitting needle 20 and nose 12 rising ramps by tight rapidly, so promptly can allow the veil 30 in knitting needle 20 pinhocks that filling 31 is pushed into the position shown in Fig. 8.

In the position shown in Fig. 9, veil 30 just moves to protruding nose 122 places of peak above nose 12, and knitting needle 20 is also by the extreme lower position bottom out, and this also is specification setting place of Towel gasket.Filling 31 then just is positioned at and reverses groove 132 places, because this moment, veil 30 was in the most tight position, so be positioned at peak in knitting needle 20 pinhock inboards, and filling 31 that will be more loose is pushed to rear side (side that takes among the figure).

Continue to move forward and knitting needle 20 when continuing to move up at sinker 10, veil 30 breaks away from protruding nose 122 positions of noses 12 peaks and is relaxed state, and filling 31 then disengaging reverses groove 132 and second protuberance in the throat 13 that reclining moves.So, promptly reeling because of the friction of filling 31 makes the filling 31 that is arranged in knitting needle 20 pinhocks do secondary anti-package action with respect to veil 30, be that veil 30 is made clockwise place-exchange with filling 31 in the pinhock of knitting needle 20, thereby form the state shown in Figure 11.

In Figure 11, for the ease of showing the relativeness of veil 30 and filling 31, so adopt the diagramatic way of exaggeration.In fact, this moment, veil 30 formed twice anti-package in the knotting position with filling 31, and the structure of knotting position is more strengthened.Then, promptly can make veil 30 and filling 31 be subjected to the drive of knitting needle 20 and shift to broken yarn portion 123 as shown in Figure 12 because of moving on of sinker 10.

As making cloth with Towel gasket, then need not broken yarn portion 123 to be set at nose 12 ends of the present utility model, so, when sinker 10 is return once more, promptly can form complete Towel gasket.As will make the towel cloth of fine hair formula the time, can cooperate 123 designs of the terminal upper limb broken yarn of nose 12 portion, when sinker 10 advances to position shown in Figure 13, veil 30 can stretch downwards because of 13 guiding of the throat of arc groove shape with knotting place of filling 31, formed Towel gasket top then just moves to broken yarn portion 123 places thereby veil 30 is positioned at nose 12 tops, thereby can positively veil 30 be cut off by broken yarn portion 123, be formed the towel cloth of lint formula.

Again among sinker 10 advances, this broken yarn portion 123 fails once veil 30 with Towel gasket when cutting off, and this Towel gasket promptly can be deviate from the belly 11 of sinker 10 when sinker 10 is stepped back.But when sinker 10 carries out when ring of making of next Towel gasket, the belly 11 of sinker 10 can penetrate earlier in the not cut Towel gasket, and Towel gasket is upwards strutted by the upper flange 111 of belly 11, because the peak height of this upper flange 111 will be high than nose 121, so can make this Towel gasket when sinker 10 advances, be sheathed with above the nose 12, can not enter in the throat 13 along belly 11, so can make the Towel gasket cut-out that before not cut off in the ring operation, and can guarantee to make the quality of lint formula towel cloth product at another.
