Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined to clearly and completely describe the technical solutions of the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In this embodiment, the warp-knitted artificial turf is woven.

As shown in fig. 1-2, a two-needle bed warp knitting mechanism based on a knife needle comprises a latch needle 1 and a knife needle 2 arranged opposite to the latch needle 1, and a guide bar mechanism arranged above the latch needle 1 and the knife needle 2, one side of the latch needle 1 is provided with a sinker 3 matched with the latch needle, the knife needle 2 can move up and down and reciprocally and move towards or away from the latch needle 1, the guide bar mechanism comprises a base cloth guide bar capable of swinging above the latch needle 1 and laying yarn on the latch needle 1, and a yarn feeding guide bar 4 capable of swinging above the latch needle 1 and the knife needle 2 and carrying out laying yarn and feeding yarn, the knife needle 2 comprises a knife needle body 21 and a needle knife 22 obliquely arranged on the top of the knife needle body 21, and a cutting edge 23 of the needle knife 22 is arranged on the side edge thereof.

The base cloth guide bar comprises a looping guide bar 5 and a weft insertion guide bar 6, the looping guide bar 5 and the weft insertion guide bar 6 are used for carrying out yarn laying on the weaving of the base cloth, in the looping process, the looping guide bar 5 and the weft insertion guide bar 6 need to carry out yarn laying on a latch needle 1, a yarn feeding guide bar 4 is used for winding grass filaments on a cutter needle 2 and carrying out yarn laying on the latch needle 1, and the number of yarn laying can be determined according to the distance between adjacent clustered grass filaments. The feed bar 4 and the backing bar are therefore not synchronized in their movement, and therefore the backing bar and the feed bar 4 employ respective bar drive mechanisms.

The latch needle 1 is mounted on a latch needle bed 7.

Referring to fig. 2, in order to ensure the cutting effect of the looped grass, the included angle between the needle knife 22 and the knife needle body 21 is 120-140 °.

Preferably, the included angle between the needle knife 22 and the knife needle body 21 is 130-135 degrees.

The included angle between the needle knife 22 and the knife needle body 21 is 133 degrees.

The cutting edge 23 is double-faced in order to ensure the lengths of the two clusters of grass filaments to be equal because of the looped grass filaments or the two clusters of grass filaments formed after cutting.

In order to facilitate the installation of the knife needle 2, a needle butt 24 is arranged at the lower part of the knife needle body 21, and the knife needle 2 is installed on the needle groove plate 8 through the needle butt 24.

In the warp knitting process, in order to ensure the width of the warp-knitted lawn, a plurality of knife needles 2 need to be installed on the needle groove plate 8 in parallel, so that the hammer 24 is arranged to facilitate the matching of the knife needles 2 and the needle groove plate 8, thereby fixing the knife needles 2. And the needle hammer 24 is arranged on the side of the needle body 21 opposite to the extending direction of the needle knife 22.

When cutting off the looped grass, the cutter needle 2 needs to move downwards, in order to realize the downward movement of the cutter needle 2, a cam 9 is arranged on one side of the slot plate 8, which is far away from the latch needle 1, a convex block 10 matched with the cam 9 is arranged on the side surface of the slot plate 8, which faces the cam 9, and a return spring 11 is arranged at the bottom of the slot plate 8.

When the cam 9 rotates, the lug 10 is hit downwards to drive the slot plate 8 and the cutter needle 2 to move downwards rapidly, and the return spring 11 is compressed, so that the cutting edge 23 of the cutter needle 2 is used for cutting off the ring-shaped grass filaments, and after the grass filaments are cut off, the slot plate 8 can rise through the elasticity of the return spring 11 to return, and the grass filaments in the next cycle are cut off.

In order to provide power for the rotation of the cam 9, the needle groove plate 8 is slidably mounted on a needle bed 12, and a servo motor 13 in transmission connection with the cam 9 is arranged on the needle bed 12.

Specifically, a driving wheel 14 is mounted on an output end of the servo motor 13, the driving wheel 14 is connected with a driven wheel 16 through a transmission belt 15, the driven wheel 16 rotates coaxially with the cam 9, and therefore the rotation of the servo motor 13 drives the cam 9 to rotate, so that the downward movement of the needle groove plate 8 and the knife needle 2 is realized.

In order to realize the guiding effect on the movement direction of the knife needle 2, a vertical sliding groove 17 is arranged on the knife needle bed 12, a sliding block 18 matched with the sliding groove 17 is arranged on the needle groove plate 8, and the sliding block 18 is slidably arranged in the sliding groove 17.

Preferably, the sliding groove 17 is a convex sliding groove, and the sliding block 18 is a convex sliding block matched with the convex sliding groove, so that the needle groove plate 8 can be prevented from being separated from the needle bed 12.

In order to adjust the length of the grass filaments conveniently, the knife and needle bed 12 is installed on the support 19, a telescopic rod 20 is arranged on one side, away from the latch needle, of the knife and needle bed 12, and the telescopic rod 20 is fixed on the support 19.

Preferably, the contact surface between the needle bed 12 and the holder 19 is provided with a sliding member such as a slide rail, which ensures the smoothness of movement of the needle bed 12.

The telescopic end of the telescopic rod 20 is connected with the knife needle bed 12, and the distance between the knife needle 2 and the latch needle 1 can be controlled through the telescopic end, so that the length of the grass filaments can be adjusted.

The telescopic rod 20 can select the components capable of realizing linear motion, such as an air cylinder, an oil cylinder, an electric push rod and the like.

Before knitting the artificial warp-knitted lawn, the length between the cutter needle 2 and the latch needle 1 is first adjusted by the telescopic rod 20 according to the length of the required filament. During weaving, backing fabric sley bar and yarn feeding sley bar 4 are laid yarn on latch needle 1, thereby latch needle 1 carries out the lopping, moves back the knitting of circle realization backing fabric, and at the in-process that the backing fabric was woven, yarn feeding sley bar 4 can be walked around the grass silk on cutter needle 2, and after latch needle 1 moved back the circle a plurality of times, cutter needle 2 moved down rapidly, cut apart the circle form grass silk and form two independent grass silks of cluster. The times of looping and looping back on the knife needle 2 and the times of lapping on the latch needle 1 can be determined according to the grass filament density of the warp-knitted artificial lawn.

This embodiment is illustrated with a warp knitted turf, and pile fabrics or other fabrics of similar construction are equally suitable.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
