Technical Field

The utility model belongs to the technical field of warp knitting machine equipment technique and specifically relates to a merchant card warp knitting machine let-off motion.

Background

In textile manufacturing, a warp knitting machine is a very important apparatus for simultaneously forming knitted fabrics by knitting a plurality of sets of parallel arranged yarns on all the working needles of a warp feed machine. In a typical large warp let-off mechanism of a warp knitting machine, yarn is continuously fed out in a rotating manner, the diameter of the yarn wound off the entire let-off roller is gradually reduced, the angular speed of rotation of the let-off roller is not changed, but the yarn take-off speed is reduced with the reduction of the diameter of the yarn wound off, and the yarn which is originally tensed may be loosened.

SUMMERY OF THE UTILITY MODEL

In order to overcome current tricot machine and reduce and then lead to the loose not enough of yarn along with yarn book diameter reduction back yarn tensile force at the let-off process, the utility model provides a let-off device for jacquard warp knitting machine carries out the let-off in-process at let-off roller and warp book section of thick bamboo, pushes down the tensile force that realizes the yarn on the yarn with its tensioning compression roller at its spring unit's the support of dragging, and spring unit's elasticity can be adjusted according to its quantity and change.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a merchant card warp knitting machine is with sending warp device, includes the tricot machine frame, rotates in the tricot machine frame to be connected with the let-off roll and send the warp roller on coaxial being provided with a warp beam section of thick bamboo, it is equipped with the bracing piece just to be located the let-off roll top in the tricot machine frame, the bracing piece both ends are fixed in the tricot machine frame through two supporting shoes, send the warp roller both sides and be located and be fixed with two spacing dishes in the tricot machine frame, and spacing dish center has the rotary rod through rotation axis connection, connects a tensioning compression roller of fixedly connected with between two rotary rods on two spacing dishes, be connected through spring unit between bracing piece and the tensioning compression roller.

Furthermore, the limiting plate comprises limiting holes which are arranged on the circumference of the limiting plate in a circumferential and circumferential manner and are used for limiting the position of the rotating rod.

Further, the spring assembly is composed of at least two telescopic springs and is connected between the supporting rod and the tensioning and compressing roller.

Furthermore, both ends of the telescopic spring are provided with hooks.

Furthermore, the supporting rod and the tensioning compression roller are hinged with shackles, the number of which corresponds to that of the extension springs.

The beneficial effects of the utility model are that, the utility model discloses a merchant card warp knitting machine is with let-off device sends the in-process at let-off roller and a book warp section of thick bamboo, with its tensioning compression roller at its spring unit pull support push down the tensile force that realizes the yarn on the yarn, spring unit's elasticity can be adjusted according to its quantity and change, and then the yarn that adapts to different density is woven, provides its suitable tensile force, the effectual warp knitting machine of having avoided of the device can loose problem at the yarn that send the warp in-process original tensioning.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the present invention;

FIG. 2 is a side view of FIG. 1;

fig. 3 is a partially enlarged view of a portion a in fig. 1.

In the figure, 1, a warp knitting machine frame, 2, a let-off roller, 3, a warp winding drum, 4, a support rod, 5, a support block, 6, a limiting disc, 7, a rotating shaft, 8, a rotating rod, 9, a tensioning compression roller, 10, a spring assembly, 11, a limiting hole, 12, an expansion spring, 13, a hook and 14, and a hook ring are arranged.

Detailed Description

As fig. 1 is the utility model discloses a structure schematic diagram, a merchant card warp knitting machine warp feeding device, including tricot machine frame 1, rotate on the tricot machine frame 1 and be connected with let-off roller 2 and go up coaxial being provided with warp winding drum 3, be equipped with bracing piece 4 just be located let-off roller 2 top on the

tricot machine frame

1, 4 both ends of bracing piece are fixed on tricot machine frame 1 through two supporting shoes 5, let-off roller 2 both sides just are located and are fixed with two spacing dishes 6 on the tricot machine frame 1, and spacing dish 6 center is connected with rotary rod 8 through rotation axis 7, connects tensioning compression roller 9 of fixedly connected with between two rotary rods 8 on two spacing dishes 6, be connected through spring assembly 10 between bracing piece 4 and the tensioning compression roller 9.

Referring to fig. 1 and 2, the limiting disc 6 is circumferentially and circumferentially provided with limiting holes 11 for limiting the position of the rotating rod 8. Spacing hole 11 is used for carrying out limiting displacement to rotary rod 8, when placing tensioning compression roller 9 on rotary rod 8 to the position when realizing the tensioning to the yarn, inserts in the spacing hole 11 of the rotary rod 8 left and right sides with the round pin axle, realizes that rotary rod 8's scope nature is spacing, has avoided tensioning compression roller 9 turned angle too big to hinder to the yarn or the too big yarn that breaks of its tensioning force of rotation angle messenger.

As shown in fig. 1 to 3, the spring assembly 10 is composed of at least two extension springs 12 and is connected between the support rod 4 and the tension and compression roller 9. The two ends of the extension spring 12 are provided with hooks 13. The supporting rod 4 and the tension compression roller 9 are both hinged with shackles 14 with the number corresponding to the number of the extension springs 12. The hook-and-loop connection of the hook 13 and the hook ring 14 is convenient for connection and disassembly, and the pressing tension of the tension compression roller 9 on the yarn can be controlled and adjusted by adjusting the number of the extension springs 12.

When the device is used, in the process of sending warp by the warp sending roller 2 and the warp winding drum 3, the tensioning compression roller 9 is pressed down on a yarn under the pulling support of the spring assembly 10 to ensure that the yarn has enough tension, in the whole process of sending warp, when the diameter of the yarn which is reeled out is reduced and the yarn becomes loose, the tensioning compression roller 9 continues to press down under the influence of gravity to ensure that the yarn continues to keep enough tension, in the process, a certain gap exists between pin shafts in the limiting holes 11 on two sides of the rotating rod 8 to facilitate the small-amplitude pressing rotation of the tensioning compression roller 9, the elasticity of the spring assembly 11 can be adjusted and changed according to the quantity of the spring assembly, so that the device is suitable for knitting yarns with different densities to provide proper tension, and the device effectively avoids the problem that the originally tensioned yarn of a warp knitting machine can be loose in the process of sending warp.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
