Abstract
The utility model is to change the present 1515K shuttle loom into the flexible rapier loom; the utility model is characterized in that the rapier leading system is a four-rods mechanism of the crank short connecting rod; the four-rods mechanism of the crank short connecting rod transmits through the gear rack and is combined with the swing of the sley. The utility model is also characterized in that a similar stop movement is arranged outside the cloth edge when the rapier moves away from the shuttle port. The mechanism can keep the components of the original machine in the largest degree and adopt a pair of changing tooth gears; therefore, the utility model can be used for the requirements of different sley waves.
Description
The utility model relates to existing 1515K fly-shuttle loom and transform flexible rapier loom as, and particularly drawing the sword system is the flexible rapier loom of crank short connecting rod four-bar mechanism by tooth bar transmission sword belt.
At present, domestic 1515K fly-shuttle loom only is used to knit sheetings, though its reed width is wide by (2.3; 2.5; 2.8 three kinds in rice), productivity ratio higher (people's latitude rate is higher than 1511,1515 looms between 334～378 meters/minute), but belong to loose reed, there is not colour changing latitude mechanism again, an incandescence in can only being applicable to.And present international novel flexible rapier loom such as TP500, SM92 etc., reed width are between 2～4 meters, and all coloured knitting changed latitude mechanism, all is fast reed, and product scope is wide.
The utility model is to change flexible rapier (fast reed) loom on the 1515K loom into.The domestic report that does not still have this respect work at present.
Though TP400 that external Italian Nuove pignone produces and TP500 also pass sword with crank short connecting rod four-bar mechanism, but they are without the tooth bar transmission, but with sector gear and the transmission of internal gear planetary mechanism, so can not be suitable for to the beating-up mechanism of traditional long lay sword.The Italy's CINCLA CTR of company flexible rapier loom is reciprocal by self swinging by flexible band transmission sword belt of slay.The easily elongation of flexible band, sword head overshoot is big, and the sword belt traverse is difficult to regulate, and the idle running that the sword head leaves behind the fell is bigger, and the floor space of machine is big.And the described weft insertion device of European patent 21-720 on March 7 in 1979 is used for the rigid rapier transmission, and is also inapplicable.
It is the flexible rapier loom that crank, short connecting rod four-bar mechanism pass through tooth bar transmission sword belt with the 1515K weaving loom modification that the purpose of this utility model provides a kind of, and the sword head equation of motion is:
S＝X· (2R)/(mZ

After GH value substitution (1), (2) formula, can obtain tooth bar traverse and arrow shaft traverse respectively.(1) Z in the formula

The utility model relatively is applicable to the four connecting rods loom that beats up, and can keep the characteristics of long lay sword, is suitable for the transformation of fly-shuttle looms such as 1515K.The sheerly positive drive of its rapier transmission mechanism, sword belt traverse are convenient to regulate, and idle running and floor space are less.
The utility model has at utmost kept the parts of original loom, adopts original lay sword, hand in hand, and mobile 100～200 millimeters backwards of rocker centers, and original opening, batch, mechanism such as the warp let-off all can be constant substantially.Because the characteristics of this rapier transmission mechanism are to be combined to off-centre and short connecting rod mechanism driving and with the swing of slay; make the motion of sword head after it leaves shed open; one approximate dead time was arranged outside selvedge; this can make time that the sword head enters shed open later; withdrawing from the time of shed open does sth. in advance a little; can suitably reduce the extruding of warp thread, shorten the lateral dimension of loom simultaneously the sword head.Because of adopting the tooth bar transmission to prolong component's life, adopting positive drive not exist because of cog belt in use produces elongation influences the normal problem that joins of sword head.The utility model also adopts Couple Change Gear, need applicable to the production of different reed widths.
The sword mechanism of drawing of the present utility model does following detailed description with implementing in conjunction with the accompanying drawings:
Of the present utility modelly draw sword mechanism as shown in drawings.ABCD is a beating-up mechanism among the figure, and wherein D is the rocker center, and its position is moved 100～200 millimeters backward on former machine.Bar 2,3 is for leading along by hand and crank, and is all same with former machine.Bar 4,5,6 and frame are formed AEFG wefting insertion quadric chain.Bar 5 is wefting insertion short connecting rod EF, and bar 4 is wefting insertion crank AE, and bar 6 is the dihedral bar.The length ratio of EF/AE is 1.7～2.7.The fulcrum of dihedral bar GH is arranged in the lower-shaft in the heart.During bar 4 revolutions, angular pole 6 is swung, driven upper and lower slip in the guide groove of tooth bar 9 on lay sword 1 through connecting rod 7, this motion drives pinion 10(Z with the synthetic back of the motion of lay sword 1
1), again through a pair of gear 11(Z

3The coaxial sword wheel 14 that draws is made reciprocating rotating, drives sword belt and carries out wefting insertion.
Is the 1515K weaving loom modification flexible rapier loom of crank short connecting rod four-bar mechanism by tooth bar transmission sword belt (12), is listed as follows corresponding to some mechanism parameters of different reed widths, the reference value of technological parameter:
