Abstract
The utility model discloses a jacquard guide needle of a warp knitting machine. The jacquard guide needle of the warp knitting machine comprises a piezoelectric ceramic piece and a needle rod connected with the piezoelectric ceramic piece, wherein the piezoelectric ceramic piece is sheet-shaped, a needle hole for a yarn to penetrate is formed at the lower end of the needle rod, and shock-absorption damping parts made from shock-absorption damping materials are arranged on one side face or two side faces of the piezoelectric ceramic piece. The shock-absorption damping parts can be sponge or rubber which adheres to and is fixed on one side face or two side faces of the piezoelectric ceramic piece through an adhesive. The shock-absorption damping parts can be damping grease which is coated on one side face or two side faces of the piezoelectric ceramic piece. The thickness of the shock-absorption damping parts is 1mm preferably. The oscillation amplitude, the oscillation time and shift positioning time of the jacquard guide needle are decreased, friction and collision between the jacquard guide needle and a knitting needle when the jacquard guide needle performs high-speed shift motion are avoided, the service life of the jacquard guide needle is prolonged, and the operation efficiency of a device and the product quality are improved.
Description
Technical field
The utility model relates to a kind of knitting component of warp knitting machine, particularly relates to the Jacquard sley point in the warp knitting machine knitting component.
Background technology
The existing employed Jacquard sley point of jacquard warp, comprise piezoelectric ceramic piece and the shank that links to each other with this piezoelectric ceramic piece, described piezoelectric ceramic piece in the form of sheets, the lower end of described shank is provided with the pin hole for interspersed yarn, when mounted, some Jacquard sley point space certain distances are installed on the needle stand.In use there is following shortcoming in the Jacquard sley point of this structure: i.e. the oscillation amplitude of Jacquard sley point generation when energising is done to be offset at a high speed is big, duration of oscillation is long, cause the offset orientation action of Jacquard sley point in the lopping requirement stipulated time still not have end so on the one hand, cause the Jacquard sley point when skew, to collide with knitting needle generation phase scrape along on the other hand, thereby damage sley point.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of and can reduce oscillation amplitude and reduce duration of oscillation, can avoid the warp knitting machine Jacquard sley point that collides with knitting needle generation phase scrape along when being offset at a high speed.
For solving the problems of the technologies described above, the utility model adopts a kind of like this warp knitting machine Jacquard sley point, comprise piezoelectric ceramic piece and the shank that links to each other with this piezoelectric ceramic piece, described piezoelectric ceramic piece in the form of sheets, the lower end of described shank is provided with the pin hole for interspersed yarn, is provided with shock-absorbing, the damped part of being made by shock-absorbing, damping material in a side or the two sides of described piezoelectric ceramic piece.
As a kind of preferred embodiment of the present utility model, described shock-absorbing, damped part are sponge or rubber, and described sponge or rubber are pasted and fixed on the side or two sides of described piezoelectric ceramic piece by adhesive.
As another kind of preferred embodiment of the present utility model, described shock-absorbing, damped part are damping grease, and described damping grease is coated on the side or two sides of described piezoelectric ceramic piece.
Shock-absorbing of the present utility model, damped part thickness are preferably 1 millimeter between 0.3～1.5 millimeter.
After adopting such structure, since the piezoelectric ceramic piece in the utility model Jacquard sley point in a side or two sides arrange by shock-absorbing, the shock-absorbing that damping material is made, damped part, described shock-absorbing, damped part is preferably sponge or rubber or damping grease, thereby the space certain distance is installed in Jacquard sley point on the needle stand in when work, by shock-absorbing, damped part absorbs the impulsive force of Jacquard sley point when being offset at a high speed, make the oscillation amplitude of Jacquard sley point, duration of oscillation and offset orientation time significantly reduce, thereby knitting needle can not take place to wipe mutually and collide with the Jacquard sley point when guaranteeing high-speed motion, avoid the damage of Jacquard sley point, improved operational efficiency and the product quality of equipment.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is a kind of structural representation of the utility model warp knitting machine Jacquard sley point.

Referring to a kind of warp knitting machine Jacquard sley point shown in Fig. 1,2, comprise piezoelectric ceramic piece 1 and the shank 2 that links to each other with this piezoelectric ceramic piece 1, described piezoelectric ceramic piece 1 in the form of sheets, the lower end of described shank 2 is provided with the pin hole 2-1 for interspersed yarn, is provided with shock-absorbing, the damped part of being made by shock-absorbing, damping material 3 in a side or the two sides of described piezoelectric ceramic piece 1.
In the utility model, described piezoelectric ceramic piece 1 preferably links to each other with shank 2 through faller gill 4, described faller gill 4 is provided with for the slot 4-1 that inserts described shank 2, the upper end of described faller gill 4 is connected by being adhesively fixed with the lower end of described piezoelectric ceramic piece 1, described shank 2 inserts and is fixedly mounted in the described slot 4-1, as shown in Figure 1.In the utility model, described piezoelectric ceramic piece 1 also can directly link to each other with shank 2 by bonding.
As a kind of preferred embodiment of the present utility model, described shock-absorbing, damped part 3 are sponge or rubber, and described sponge or rubber are pasted and fixed on the side or two sides of described piezoelectric ceramic piece 1 by adhesive.
As another kind of preferred embodiment of the present utility model, described shock-absorbing, damped part 3 are damping grease, and described damping grease is coated on the side or two sides of described piezoelectric ceramic piece 1.
As another preferred embodiment of the present utility model, described shock-absorbing, damped part 3 are spring, and an end of described spring is installed on the side or two sides of described piezoelectric ceramic piece 1 by adhesive.
Shock-absorbing of the present utility model, damped part 3 thickness are preferably 1 millimeter between 0.3～1.5 millimeter.
When work, some described Jacquard sley point space certain distances are installed in and form Jacquard pin piece on the needle stand as yarn guide member, and are not shown in the figures.
Through on probation at jacquard warp, the utility model has reduced oscillation amplitude and the duration of oscillation of Jacquard sley point, avoid the Jacquard sley point when skew, to collide with knitting needle generation phase scrape along, improved operational efficiency and the product quality of equipment, obtained good effect.
