Abstract
The utility model relates to a rapier loom in modern shuttleless looms, belonging to the textile industry weaving devices, wherein a rapier and a set of rapier mechanism are shared by two looms, a rapier transmitting wheel 26 is arranged in the middle of the two looms, and can finish a reciprocating motion according to the set principles in a rotation circle of a spindle, and drives a rapier 25 whose two end portions are all provided with drawing rapier heads 25.1, 25.2 to finish the full range reciprocating motion in passing in and out a left and a right sheds, thereby finishing the weaving motions of two cloths, wherein 24 and 27 are respectively a left beating-up reed and a right beating-up reed, 23 and 28 are respectively a left feeding device and a right feeding device, 21 and 29 are respectively a left weft cylinder and a right weft cylinder, and 20 and 30 are respectively a right weft cutter and a left weft cutter.
Description
Technical field
The purpose of this utility model provides a kind of duplex Rapier looms, belongs to a kind of Rapier looms in the modern shuttleless loom.
Background technology
The traditional structure that textile industry is used modern widely Rapier looms rapier transmission mechanism is as shown in Figure 1:
In the left side of the loom cloth width of cloth left sword transmission wheel 11 is arranged, left sword belt 12 coats on it.The left sword belt end is installed and is sent sword head 12.1.When left side sword transmission wheel 11 rotated, transmission left sword belt 12 sent sword head 12.1 band weft yarns 14 to enter the open shed open of warp thread 15 layerings.Simultaneously the right side of the cloth width of cloth right sword belt that has right sword transmission wheel 18 will have in the same way to connect sword head 17.1 17 is sent into shed open from opposite side.When left sword belt 12 send the connecing sword head 17.1 and meet of sword head 12.1 and right sword belt 17 in the cloth width of cloth central authorities time, the weft yarn end just from left sword belt 12 send that sending of sword head 12.1 transfer to right sword belt 17 the latitude jaw connect the connecing in the latitude jaw of sword head 17.1.Withdraw from separately then, finish the wefting insertion process one time.
This filling insertion way has following shortcoming:
1. weft yarn is when the handing-over of cloth width of cloth central authorities, and the speed of two sword belts all is zero, and one time the wefting insertion process has the speed peak value twice, and velocity peak values and acceleration are all very big, and the weft tension fluctuation is fierce, is unfavorable at a high speed.
2. a loom has two covers to pass the sword system, mechanism's complexity, and power consumption is big.
3. the machine floor space is big, and not fitting into China's fly-shuttle loom especially has the board of right-hand man's branch to arrange, and the workshop area utilization is low, is unfavorable for modernizing and expanding the existing factory.
Summary of the invention
The purpose of this utility model provides a kind of duplex Rapier looms, this duplex Rapier looms is equivalent to the production capacity of two conventional art Rapier loomss and has only the floor space of two fly-shuttle looms, be specially adapted to the renewal of the equipment of China textile enterprise, have good and economic.
The duplex Rapier looms that the utility model provides is as shown in Figure 2:
A kind of duplex Rapier looms is by left board 01 and sword transmission wheel 26 that right board 02, one cover is installed in two loom central authorities and the weft insertion system that double end arrow shaft 25 is formed relatively independent, symmetric arrangement.
The left end of the double end arrow shaft 25 of straight reciprocating motion is equipped with a left side and connects latitude pincers 25.1, and right-hand member is equipped with the right side and connects latitude pincers 25.2.
About a shared arrow shaft of two boards and a cover rapier transmission mechanism, two shed opens and weft traction enter shed open about alternately entering.Sword transmission wheel 26 is placed in the central authorities of two looms, in main shaft one-period (changes), it finishes a reciprocating motion according to the rule that designs, and the transmission two ends all have the arrow shaft 25 that connects latitude pincers to shuttle back and forth between the shed open of left and right board, alternately finishes the wefting insertion process of two width of cloth fabrics.
About two boards opening respectively arranged independently, beat up, the warp let-off, spooler and weft yarn feed system, symmetric arrangement, its motion phase difference are 180 degree of main shaft.Wherein 24,27 is respectively the left and right reed that beats up; 23,28 is respectively left and right yarn feeder; 21,29 is respectively left and right weft yarn bobbin; 20,30 is respectively that cut on left and right limit.
Description of drawings
Fig. 1 is traditional Rapier looms weft insertion system sketch.
Fig. 2 is " duplex Rapier looms " weft insertion device and course of work schematic diagram.
The specific embodiment
The weft insertion device of duplex Rapier looms is as shown in Figure 2:
By about two duplex Rapier loomss that Rapier looms relatively independent, symmetric arrangement is formed, a shared cover rapier transmission mechanism is installed in two loom central authorities.
2. the two ends of the double end arrow shaft 25 of straight reciprocating motion all are equipped with one and are connect the latitude pincers, and left end has a left side to connect latitude pincers 25.1, and right-hand member has the right side to connect latitude pincers 25.2.
3. be installed in sword transmission wheel 26 transmission arrow shafts 25 left and right sides alternating movements of the rapier transmission mechanism of two loom central authorities: when moving right; connecing latitude jaw 25.1 is made up of the stator and the activity template that have the little wedge shape mouth of outer imperial palace; can catch on the end of the weft yarn 22 that weft yarn draws from left weft yarn bobbin 21, weft traction 22 enters the left side shed open.At this moment, left side reed 24 is still in the rear position, and shed open is opened; Right side reed 27 retreats into the rearmost position later on fast carrying out beating motion; The heald frame up and down of right side shed open is alternately basic to be finished, and it is " sky " that the right side that enters the right side shed open connects 25.2 on latitude pincers.When arrow shaft 25 enters the right side shed open fully, the wefting insertion process of left shed open is finished, left reed 24 beginning beating-ups, and with 22 dozens of weft yarns introducing shed open forwards (fell), the left side fabric is finished and is once weaved circulation.Then, main shaft begins to enter down half period, and sword transmission wheel 26 beginning turning anticlockwises drive arrow shaft 25 and move from right to left, and the process of motion of weft-insertion is identical, direction is opposite, finishes the wefting insertion of right side fabric and weaves circulation.So go round and begin again, realize the weaving process of two width of cloth fabrics.
Opening except rapier transmission mechanism, beat up, the warp let-off, spooler and weft yarn feed system, independent separately, symmetric arrangement.Main shaft contact of nationality, the phase difference of the period of motion are main shaft 180 degree.
The present invention has the following advantages:
1) two looms share an arrow shaft and a cover rapier transmission mechanism, and than the mechanism simplifying of two looms, the machine material loss reduces.
2) floor space obviously reduces than two looms, and the board that particularly adapts to China's fly-shuttle loom of the branch that the right-hand man is arranged is arranged Tradition, workshop area utilization height, good economy performance.
3) arrow shaft does not have bending, indefatigability, long service life; It is light to pass the sword system weight, and living load is little, energy savings.
4) under same rotational speed and the identical amplitude of weaving, the arrow shaft acceleration of motion of Chained Rapier Loom is not higher than traditional arrow shaft Loom, motion frequency reduces half, and the board vibrations reduce.
