Abstract
The utility model relates to a rapier loom weft insertion system, in particular to a guide hook. The guide hook comprises a guide hook body, and the lower portion of the guide hook body is in a type like the Arabic numeral seven. An installation hole is formed in the lower portion of the guide hook body in the vertical direction. Two wedge-shaped protrusions are arranged on the left side and the right side of the upper portion of the guide hook body in the horizontal direction of the type like the Arabic numeral seven. The two wedge-shaped protrusions are the left end wedge-shaped protrusion and the right end wedge-shaped protrusion respectively. The left end wedge-shaped protrusion and the right end wedge-shaped protrusion are respectively perpendicular to the guide hook body. A U-shaped groove is formed in the root of the left end wedge-shaped protrusion of the upper portion of the guide hook body and concaved toward the guide hook body. A required rapier band is light and thin, a rapier head is long, narrow and light in weight, inertia in the movement is reduced, the friction environment is improved, original three-face friction is improved to be single-face friction, in this way, friction is reduced, and service life of the rapier tape is prolonged. Due to the fact that guide hooks in a back row do not exist, the problem that the guide hooks in the back row hook weft yarn does not exist, loop rising will not happen on a fabric, and quality and weaving efficiency of the fabric are improved.
Description
Technical field
The utility model relates to a kind of rapier loom weft insertion system, specifically a kind of hook of leading.
Background technology
What the weft insertion system application of current Rapier looms was maximum is the double hook of leading, two row are led hook and are separately fixed at sword plate both sides, sword belt is led hook side and passes through above lower layer warp yarns from two row, this hook of leading is large to the frictional force of sword belt two sides, cause sword belt quick abrasion, service life is short, also can make weft transfer fault rate increase, impact start efficiency, in addition, sword belt bottom surface and lower layer warp yarns friction not only cause warp thread burst rate to increase, impact start efficiency, also make sword belt temperature rise fast, be difficult for high-speed cruising, moreover, weaving special kinds (as Woven glass cloth, large satin shelves fabric) time, rear row leads hook weft yarn easy to hang makes fabric play cover, cause very high float rate, thereby affect fabric quality.
Summary of the invention
The utility model is in order to make up deficiency of the prior art, provide a kind of row's guiding without issue not hang weft yarn, can improve sword belt friction environment, enhance productivity and fabric quality lead hook.
The technical scheme in the invention for solving the technical problem is: a kind of hook of leading, comprise and lead hook body, described bottom of leading hook body is " 7 " font, and be provided with installing hole on the vertical direction of bottom, described top of leading hook body is provided with two wedge shape projections along " 7 " font horizontal direction left and right sides, be respectively left end wedge shape projection and right-hand member wedge shape projection, described left end wedge shape projection and right-hand member wedge shape projection are respectively with to lead hook body perpendicular, described root of leading hook body top left end wedge shape projection is provided with a recessed guide hook intrinsic " U " shape groove.
Further, described right-hand member wedge shape projection is higher than left end wedge shape projection, and rib is led respectively in the side of described right-hand member wedge shape projection.
Further, described in lead hook body and be fixedly installed on and lead on hook installing plate through installing hole by the first bolt, described in lead hook installing plate and be fixedly installed on guide rail beam by the second bolt.
Further, on described " U " shape groove, be provided with sword belt base plate.
The beneficial effects of the utility model are: the desired sword belt of the utility model is frivolous, the long and narrow quality of gripper head is light, has reduced the inertia in motion, has improved friction environment, by three original frictions, be improved as single-sided friction and reduced frictional force, sword belt is extended service life.Owing to arranging and leading hook without male offspring, do not exist rear row to lead hook weft yarn problem, fabric can not play cover, has improved fabric quality and weaving efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is mounting structure schematic diagram of the present utility model;
In figure: 1, right-hand member wedge shape projection, 2, left end wedge shape projection, 3, " U " shape groove, 4, lead hook body, 5, installing hole, 6, sword belt base plate, 7, lower layer warp yarns, the 8, first bolt, 9, lead hook installing plate, the 10, second bolt, 11, guide rail beam.
The specific embodiment
Below in conjunction with accompanying drawing 1 to 2 pairs of the utility model of accompanying drawing, be further described:
A kind of hook of leading, comprise and lead hook body 4, described bottom of leading hook body 4 is " 7 " font, and on the vertical direction of bottom, be provided with installing hole 5, described top of leading hook body 4 is provided with two wedge shape projections along " 7 " font horizontal direction left and right sides, be respectively left end wedge shape projection 2 and right-hand member wedge shape projection 1, described left end wedge shape projection 2 and right-hand member wedge shape projection 1 be respectively with to lead hook body 4 perpendicular, described in lead hook body 4 top left end wedge shape projections 2 root be provided with " U " shape groove 3 in recessed guide hook body 4.
In the utility model, described right-hand member wedge shape projection 1 is higher than left end wedge shape projection 2, and rib is led respectively in the side of described right-hand member wedge shape projection 1.
In the utility model, described in lead hook body 4 and be fixedly installed on and lead on hook installing plate 9 through installing hole 5 by the first bolt 8, described in lead hook installing plate 9 and be fixedly installed on guide rail beam 11 by the second bolt 10.
In the utility model, on described " U " shape groove 3, be provided with sword belt base plate 6.
Operation principle of the present utility model is: the top of leading hook body 4 is provided with two wedge shapes and is raised with and is beneficial to separately lower layer warp yarns 7, the root of left end wedge shape projection 2 has " U " shape groove 3 in recessed guide hook body 4 for locating sword belt base plate 6, the robust motion that sword belt and sword belt base plate 6 are connected has increased sword belt with its motion has increased start efficiency, reduced wearing and tearing probability, increased the service life of sword belt, rib is led respectively in the side of right-hand member wedge shape projection 1 can make lower layer warp yarns 7 by smooth.
Other parts in the utility model adopt prior art, do not repeat them here.
