Description
Technical field
The utility model relates to a kind of Jacquard sley bar, particularly relates to a kind of Jacquard sley bar of warp knitting machine.
Background technology
Jacquard sley bar is suitable on tricot, make complicated flower pattern.In process of production, Jacquard sley bar can equally do overall transverse motion with other common sley bars.Meanwhile, each sley point be arranged on jacquard needle block can also be driven by piezoelectric element and do independent additional transverse motion.By the superposition of these two kinds of transverse motions, Jacquard sley bar can provide the flower pattern possibility abundanter than common sley bar.
Jacquard sley bar generally extends along the whole working width of warp knitting machine, the longlyest at present can reach 6 meters, and the cross sectional dimensions of Jacquard sley bar is much smaller than its length.This mechanical stability for Jacquard sley bar proposes very high requirement.The sley bar of Jacquard sley bar especially needs to have certain rigidity, can not exceedingly vibrate in the course of work again.On the other hand, sley bar matrix will have less quality.Because quality is less, the power in the course of the work for accelerating needed for sley bar is less, and the operating rate that warp knitting machine can reach is also higher.In addition, the thermal expansion of the Jacquard sley bar caused by variations in temperature also should be eliminated as far as possible, to prevent the change of needle gage between sley point.
Chinese patent CN201420102308, therefore suggestion carbon fibre reinforced plastic manufactures Jacquard sley bar.In practice, this technical scheme brings the mechanical stability problems of a sley bar.
Usually on warp knitting machine in order to make various knitting element, such as sley point, knitting needle, knocking-over bit etc. can closely cooperatings, and all knitting elements all concentrate in the woven extent of limited space.Multiple sley bars of warp knitting machine in fan-shaped arrangement, are outwards dispersed on its cross section by woven extent.Like this, each sley bar is assigned to an angular interval on sector.Such angular interval is usually less, is in general approximately 8 to 15 degree.Single sley bar cross section is narrowed to the part near woven extent gradually by the part away from woven extent.
Such space constraint brings mechanical stability problems to above-mentioned carbon fiber Jacquard sley bar.Because the jacquard needle block be fixed thereon has certain thickness, sley bar matrix must make very thin near the part of woven extent.Although and carbon fibre material has the rigidity higher than the traditional metal materials (such as magnesium alloy) of equal quality, equal volume relatively under then relatively weak.Therefore, can there is excessive vibration in the course of the work in the region that carbon fiber sley bar matrix is excessively thin, thus affect sley point and weave motion accurately, can affect fabric quality and even cause knitting element to collide time serious.
Utility model content
The utility model is intended to address the aforementioned drawbacks, and provides a kind of Jacquard sley bar of warp knitting machine.
In order to overcome the defect existed in background technology, the utility model solves the technical scheme that its technical problem adopts: the Jacquard sley bar of the Jacquard sley bar of this warp knitting machine comprises sley bar matrix that extend along machine length direction, that be made up of carbon fibre reinforced plastic, and multiple jacquard needle block along sley bar length thereof direction spread configuration, each jacquard needle block is connected with sley bar matrix phase by a connector be made up of metal material, is provided with gap between described adjacent connections.
According to another embodiment of the present utility model, comprise described connector further and be made up of magnesium alloy.
According to another embodiment of the present utility model, comprise described connector further and be fixed on sley bar matrix by screw.
According to another embodiment of the present utility model, comprise described connector further and clamp with jacquard needle block and be connected.
The beneficial effects of the utility model are: the Jacquard sley bar of this warp knitting machine is by using the connector of metal material formation, very thin thickness can be had in space limited near woven extent, there is enough rigidity simultaneously, to avoid vibration excessive in the course of work, the sley bar matrix that carbon fibre reinforced plastic is made then only is positioned at the more sufficient space away from woven extent, therefore the rigidity that enough volumes reach enough can be utilized, arranging gap between adjacent connections can prevent the thermal expansion of metal connecting piece from accumulating on the length direction of sley bar matrix, each connector allows thermal expansion to a certain degree, and the relative position of each jacquard needle block can not be affected, also sley bar matrix can not be made to bear load and be out of shape.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Wherein: 1, sley bar matrix, 2, connector, 3, screw, 4, jacquard needle block.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, Jacquard sley bar comprises sley bar matrix 1 that extend along machine length direction, that be made up of carbon fibre reinforced plastic, and multiple jacquard needle block 4 along sley bar matrix 1 length direction spread configuration, each jacquard needle block 4 is connected with sley bar matrix 1 by a connector be made up of metal material 2, is provided with gap between adjacent connections 2.Connector 2 is fixed on sley bar matrix 1 by screw 3.Connector 2 clamps with jacquard needle block 4 and is connected.
The connector 2 be made up of metal material can have very thin thickness in space limited near woven extent, but has enough rigidity simultaneously, to avoid vibration excessive in the course of work.Connector 2 can be made up of magnesium alloy.
The sley bar matrix be made up of carbon fibre reinforced plastic 1 is only positioned at away from woven extent, has in more sufficient space, therefore can utilize the rigidity that enough volumes reach enough.
Can prevent the thermal expansion of metal connecting piece 2 from accumulating on the length direction of sley bar matrix 1 by arranging gap between adjacent connections 2.Each connector 2 allows thermal expansion to a certain degree like this, and can not affect the relative position of each jacquard needle block 4, and sley bar matrix 1 also can not be made to bear load and be out of shape.
