Abstract

The utility model discloses a sinker of a flat knitting machine, which belongs to the technical field of textile machinery. The sinker comprises a needle bell part, a pressing part and a rotatable part; wherein, the pressing part is provided with two pressing ends; the rotatable part of the sinker is oppositely mounted on the upper end of a needle plate by a rotary shaft; a plurality of sinkers form an extended strip; both the needle bell part and the pressing part of the sinker can rotate along with the rotary shaft for a certain angle; the pressing ends of the two oppositely arranged sinkers are contacted with each other. The pressing part of the sinker of the flat knitting machine has a double-pressing effect, pressing not only a coil on the owned side but also a coil on the opposite side; even though the pull of a traction device is too low, the pressing part of the sinker can still firmly press the coils; consequently, even though pull is not pressed, the coils cannot be lifted along with crochet hooks, thus avoiding the occurrence of coil accumulation.

Description

The sinker of straight-bar machines

Technical field

The utility model relates to a kind of textile machine, particularly relates to a kind of sinker of straight-bar machines.

Background technology

As shown in Figure 1, the sinker of existing straight-bar machines generally has rotation section 1, needle central portion 2, press section 3, and sinker 4 is opposition by rotation section 1 and is installed on the needle-bar 5 of straight-bar machines, change by the operation of needle central portion 2 in the sedimentation track, realize that the coil on the 3 pairs of crochet hooks 6 in press section is pushed.The defective of the existence of existing sinker is: the press-side 8 of the press section 3 of sinker 4 also has certain distance with the back side of opposite crochet hook 6, when crochet hook 6 and crochet hook 9 risings, the press-side 7 of sinker 4 can be pushed the coil on the crochet hook 9, and press-side 8 can not be pushed the coil on the crochet hook 6, therefore, sinker 4 can only be pushed the coil of this face, if coil is pine too, the pushing the position and just can not effectively push or leak pressure of sinker 4 to coil, like this, if the pulling force of pulling device is too small, coil will be followed crochet hook and be risen together and cause the tuck phenomenon, influences the quality of knitting.

The utility model content

For solving the existing defective of above-mentioned existing issue, the purpose of this utility model provides a kind of sinker of straight-bar machines, comprise needle central portion 20, press section 30, rotation section 40, press section 30 has press-side 31, press-side 32, the rotation section 40 of sinker 10 is on the spot being installed in the upper end of needle plate 60 by rotating shaft 50, form one by a plurality of sinkers 10 and extend band, the needle central portion 20 of sinker and press section 30 can rotate to an angle along with rotating shaft 50, and the press-side 31 that is two sinkers 10 of opposition setting contacts.

During work, when crochet hook 70 rises, the press-side 31 of sinker can be pushed the coil on the crochet hook 70, simultaneously, when crochet hook crochet hook 80 rose, the press-side 32 of sinker 10 also can be pushed the coil on the crochet hook 80, therefore, when if crochet hook 70 and crochet hook 80 rise simultaneously, the press-side 31 of sinker 10, press-side 32 can both be pushed the coil on crochet hook 70, the crochet hook 80.

The sinker that is suitable for braiding flat-bed machine described in the utility model, the position of pushing of sinker has dual effect of pushing, it not only can push the coil of this face, can also push the coil on opposite, even the pulling force of pulling device is too small, the pushing the position and also can push coil firmly of sinker, like this, even do not having under the situation of pulling force, coil can not followed crochet hook yet and be risen together, and the phenomenon that does not just have tuck takes place.

Below in conjunction with Fig. 2 and Fig. 3 the utility model is described further.

Description of drawings

Fig. 1 is the fundamental diagram of existing straight-bar machines sinker;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is a fundamental diagram of the present utility model.

The specific embodiment

As shown in Figure 2, sinker 10 described in the utility model comprises needle central portion 20, press section 30, rotation section 40, and press section 30 has press-side 31, press-side 32.

Please again in conjunction with shown in Figure 3, the rotation section 40 of sinker 10 is on the spot being installed in the upper end of needle plate 60 by rotating shaft 50, form one by a plurality of sinkers 10 and extend band, the needle central portion 20 of sinker and press section 30 can rotate to an angle along with rotating shaft 50, and the press section 30 that is two sinkers 10 of opposition setting contacts.As seen from Figure 3, during work, when crochet hook 70 rises, the press-side 31 of sinker 10 can be pushed the coil on the crochet hook 70, simultaneously, and when crochet hook crochet hook 80 rises, the press-side 32 of sinker 10 also can be pushed the coil on the crochet hook 80, therefore, if when crochet hook 70 and crochet hook 80 rise simultaneously, the press-side 31 of sinker 10, press-side 32 can both be pushed the coil on crochet hook 70, the crochet hook 80.Like this, even do not having under the situation of pulling force, coil can not followed crochet hook yet and be risen together, and the phenomenon that does not just have tuck takes place.

Claims

1, a kind of sinker of straight-bar machines, comprise needle central portion 20, press section 30, rotation section 40, sinker 10 is needle plate 60 upper ends on the spot being installed in straight-bar machines by rotation section 40, it is characterized in that: the press section 30 of sinker 10 is provided with press-side 31, press-side 32, and the press-side 31 that is two sinkers 10 of opposition setting contacts.
