Description

Warp yarn distributing system

Technical Field

The invention relates to a plastic circular weaving machine, in particular to a warp yarn and cloth yarn system.

Background

The commonly known plastic circular weaving machine has the common problem of warp yarn scraping when the warp yarn of the circular weaving machine is opened and moved, the warp yarn is directly fluffed and broken, the weaving performance and speed are influenced, particularly, when thick yarns and thin yarns are woven, the circular weaving machine can only reduce the speed to operate, and otherwise, the circular weaving machine is frequently stopped when the warp yarn is broken. The main reasons are as follows: 1. the inner palm fiber, the outer palm fiber and the jumper bar are arranged wrongly, the inner palm fiber and the outer palm fiber are generally arranged at equal intervals, the number of guide grooves of a jumper bar guide plate is larger than that of the jumper bar, the angles of the guide grooves are not correct, the guide grooves are not distributed along the radial direction of the jumper bar, the warp fibers and palm fiber eyes are scratched, and the jumper bar and the wall of the guide grooves are rubbed to play a role in guiding; 2. when the plastic circular weaving machine is introduced, the structure of the door ring reed is not available originally, and the door ring reed is arranged later for safety protection. The setting of door ring reed door influences the threading convenience, for the drawing is convenient, often reduces the reed number of teeth, and some suddenness do not establish the reed door. In fact, the coil reed is very important for the weaving performance. When the shuttle moves circularly, the guide rod of the shuttle is always attached to the warp yarn, and the friction force of the guide rod causes the warp yarn to be deviated forwards, so that the warp yarn on the outer palm yarn is scratched with the eye of the adjacent inner palm yarn to be wound or broken.

Although the national patent of heald belt assembly and circular weaving machine (201820657468.1) improves the palm fiber arrangement of the palm belt, the palm fiber can be prevented from being scratched, but the problem of the scratch of the warp fiber can not be thoroughly solved without the correct arrangement of a jumper bar and a door ring reed door.

Disclosure of Invention

The invention aims to provide a warp yarn distribution system which can avoid the scratch between warp yarns and inner and outer palm yarns and improve the weaving performance.

In order to achieve the purpose, the invention adopts the following technical scheme that a warp yarn wire distribution system comprises a door ring, reed teeth, inner palm yarns and outer palm yarns on a palm belt, and further comprises a jumper bar and a jumper bar guide plate, wherein the inner palm yarns, the outer palm yarns and the jumper bar are provided with warp yarns, the jumper bar guide plate is provided with a guide groove, the jumper bar is arranged in the guide groove, the inner palm yarns and the outer palm yarns are arranged according to an equal central angle α, the inner palm yarns are circumferentially deflected α/2 relative to the outer palm yarns, the number of the guide groove is equal to the sum of the inner palm yarns and the outer palm yarns, an included angle 68 of the guide groove is equal to α/2, reed teeth are arranged on the same circumference of the door ring, the number of the reed teeth is equal to the number of the guide grooves or equal to 1/2, the central angle of the reed teeth is equal to 352 when the number of the corresponding reed teeth is equal to the number of the guide grooves, the central angle of the reed teeth is equal to an included angle 2 of the guide groove when the number of the reed teeth is equal to the number of the guide grooves, the inner reed teeth and the outer teeth are equal to the number of the guide groove angle of the inner reed teeth and the inner teeth and the outer teeth and the inner teeth and the outer teeth are equal to the peripheral angle of the guide groove of the reed teeth of the guide groove, the reed teeth of.

Furthermore, the jumper bar is movably matched with the guide groove, so that the flexible and reliable work of the jumper bar is ensured.

After the technical scheme is adopted, the invention has the following advantages: when the warp yarn is in the alternative movement, the warp yarn does not interfere with the inner palm yarn eye and the outer palm yarn eye, so that the scratch is minimized, the defects of warp breakage, warp yarn winding by the palm yarn eyes and the like are greatly reduced, the knitting performance is improved, and the knitting speed can be further improved.

Drawings

The invention will be further described with reference to the accompanying drawings in which:

FIG. 1 is a schematic structural diagram according to a first embodiment of the present invention;

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

fig. 3 is a top view of another structure of fig. 1.

Detailed Description

The first embodiment is as follows:

the warp yarn distribution system comprises reed dent 2, inner palm yarn 31, outer palm yarn 32 and a guide plate 5 for guiding a skipping rod 6 on a door ring 1, wherein the number of the inner palm yarn and the outer palm yarn is 6 respectively, the central angles α corresponding to adjacent palm yarns in each group of the palm yarns are equal and equal to 0.8 degrees, the guide plate is provided with 12 guide grooves 7, each guide groove is internally provided with a skipping rod, the included angle β of the adjacent guide grooves is equal to 0.4 degrees, the number of the reed dent 2 is 12, the adjacent included angle β is 0.4 degrees and is arranged on the same circumference of the door ring, the reed dent is circumferentially deflected by 0.2 degrees relative to the guide grooves, the positioning circular radius R of the skipping rod is 900mm, the central angle (namely the guide groove included angle β) of the adjacent skipping rod is equal to 0.4 degrees, the thickness h of the skipping rod is equal to 0.4/180 degrees, the thickness h of the skipping rod is equal to 3.14 mm, 6.2mm, the accuracy is enough to ensure that the skipping rods are arranged in the radial direction, the warp yarn distribution is not equal to the inner palm yarn scraping eyes, and the warp yarn is not mutually interfered with the shuttle eyes of the door ring, and the warp yarn scraping effect of the warp yarn is avoided, and the warp yarn scraping is not equal to the shuttle pushing eyes of the warp yarn scraping.

Furthermore, the diameter of the steel wire of the jumper 6 is 2mm, and the width of the guide groove 9 is 2.1mm, so that the gap fit between the jumper and the guide groove is ensured.

Example two:

as shown in fig. 3, the invention provides a warp yarn distributing system, which reduces the number of dents by half, the number of dents 2 by 6, the adjacent included angle is equal to 0.8 degrees, and the number of dents is reduced by half, thereby simplifying the structure.
