Abstract
The utility model relates to the technical field of sley bar, particularly relates to a kind of piezoelectric jacquard sley bar.The centre of sley bar matrix is provided with the cavity extended along whole sley bar length, and sley bar matrix is made up of carbon fibre reinforced composite.This piezoelectric jacquard sley bar has very high robustness, and its quality significantly reduces compared to light metal material, thus need not increase substantially driving power, and improves the operation of a machine speed.In addition, due in machine operation temperature range, expanding with heat and contract with cold of carbon fibre reinforced composite is almost negligible, so can get rid of the problem causing needle gage to change by variations in temperature.
Description
Technical field
The utility model relates to a kind of sley bar, particularly relates to a kind of piezoelectric jacquard sley bar.
Background technology
Piezoelectric jacquard sley bar is usually used on tricot, make complicated flower pattern.Knitting needle on piezoelectric jacquard sley bar can be driven by piezoelectric element, while do whole lateral moving motion along with sley bar matrix, does specific additional traversing separately individually.These two kinds of transverse motions can overlap each other, thus produce abundant flower pattern possibility.
Piezoelectric jacquard sley bar is everlasting on the one hand in multi-bar warp knitting machine and is come into operation.In multi-bar warp knitting machine, piezoelectric jacquard sley bar is arranged on fixed suspension bracket together with other sley bar.In volume process, piezoelectric jacquard sley bar only moves on sideslip direction, and can not do oscillating motion perpendicular to sideslip direction.On the other hand, piezoelectric jacquard sley bar is also everlasting, and some have in the Raschel looms of less sley bar and come into operation, the RSJ series warp knitting machine such as produced by Ka Er Meyer company.In this class warp knitting machine, piezoelectric jacquard sley bar is arranged in swing arm together with other sley bar.In volume process, piezoelectric jacquard sley bar not only moves on sideslip direction, and also can do oscillating motion perpendicular to sideslip direction.
Piezoelectric jacquard sley bar generally can extend with longer length, such as the length of whole warp knitting machine fuselage.On rare occasion, its length can reach 6 meters.Even it is not under shorter situation, low to the requirement of piezoelectric jacquard sley bar matrix in mechanical stability yet.Sley bar matrix especially need have certain rigidity, can not vibrate in the course of the work.In addition, sley bar matrix also 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 therefore the warp knitting machine operating rate that can reach is larger.
The sley bar matrix of piezoelectric jacquard sley bar is made up of light metal usually, such as magnesium or aluminium.Although these materials are comparatively light comparatively speaking, the sley bar matrix made still has considerable quality.In addition, the thermal expansion of these materials is higher, because variations in temperature causes expanding with heat and contract with cold of sley bar matrix to be easy to change the needle gage between sley point placed on it, thus affects the quality of fabric, even causes the accidents such as striker.
Summary of the invention
The technical problems to be solved in the utility model is: existing piezoelectric jacquard sley bar is made up of light metal, not only there is considerable quality, and variations in temperature causes expanding with heat and contract with cold of sley bar matrix to be easy to change the needle gage between sley point placed on it, thus affect the quality of fabric, even cause the accidents such as striker, a kind of piezoelectric jacquard sley bar is provided.
In order to overcome the defect existed in background technology, the utility model solves the technical scheme that its technical problem adopts and is: comprise sley bar matrix, sley bar matrix is made up of carbon fibre reinforced composite.
According to another embodiment of the invention, the centre comprising described sley bar matrix is further provided with the cavity extended along whole sley bar length,
According to another embodiment of the invention, comprise further in described carbon fibre reinforced composite and be provided with at least one deck carbon fiber and arrange along the length direction of sley bar.
According to another embodiment of the invention, the parts of plastics comprising described carbon fibre reinforced composite further adopts polyester, epoxy resin, polyimides or BMI.
The beneficial effects of the utility model are: this piezoelectric jacquard sley bar has very high robustness, and its quality significantly reduces compared to light metal material, thus need not increase substantially driving power, and improves the operation of a machine speed.In addition, due in machine operation temperature range, expanding with heat and contract with cold of carbon fibre reinforced composite is almost negligible, so can get rid of the problem causing needle gage to change by variations in temperature.
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;
Fig. 2 is the structural representation of the utility model local;
Wherein: 1, sley bar matrix, 2, cavity.
Detailed description of the invention
As depicted in figs. 1 and 2, figure comprises sley bar matrix 1, and the centre of sley bar matrix is provided with the cavity 2 extended along whole sley bar length, and sley bar matrix 1 is made up of carbon fibre reinforced composite.Be provided with at least one deck carbon fiber in carbon fibre reinforced composite to arrange along the length direction of sley bar.The parts of plastics of carbon fibre reinforced composite can adopt polyester, epoxy resin, polyimides or BMI.
The sley bar matrix that this piezoelectric jacquard sley bar makes by such manner has very high robustness.Its quality significantly reduces compared to light metal material, thus need not increase substantially driving power, and improves the operation of a machine speed.In addition, due in machine operation temperature range, expanding with heat and contract with cold of carbon fibre reinforced composite is almost negligible, so can get rid of the problem causing needle gage to change by variations in temperature.
