Description
Technical field
The utility model belongs to textile machine, particularly relates to a kind of Flexible Rapier in Inserting Weft device of belt carcass loom.
Background technology
It all is rigid rapier weaving machine that present no shuttle-type belt carcass loom used more, and what its weft inserting apparatus used is rigid rapier, and its mechanism mainly contains following several at present: a kind of is the eccentric ratio formula.Drive eccentric ratio and diagonal control arm by shaft transmission gear in the loom, drive throwing sword plate by angle type swing arm again and swing, throw the hinge joint of sword plate top and rigid rapier, make rigid rapier, finish wefting insertion along the reciprocating motion of reed direction.Throwing sword plate bottom has a slide block to slide up and down in slide.This mechanism more complicated must be moved with slay, and arrow shaft motion has bigger empty traverse, does not have the dead time during lock seaming, and the loom lateral dimension is bigger simultaneously.
Another kind is a conjugate cam type.A pair of conjugate cam is housed on loom main shaft, and two forks and rocking bar by connecting together make rigid rapier along the reciprocating motion of reed direction by straight connecting rod and straight-line motion mechanism again.Though this mechanism can reduce the empty traverse of arrow shaft and the arrow shaft characteristics of motion that can be reasonable in design, but reasons such as inertia resistance that the space is loosening, rotating part is bigger between the not enough and wearing and tearing owing to the machining accuracy of conjugate cam mechanism, each part often, the stability of arrow shaft motion can not reach desirable requirement.
Also having a kind of is cam, fan-shaped wheeled.Make the forward and reverse swing of sectional wheel by connecting rod again by the cam driven swing arm, the shape of sectional wheel is that the part, top has tooth, and a rotary middle spindle is arranged at the bottom, and connecting rod is an end and swing arm hinge joint then, the middle part hinge joint of the other end and sectional wheel.The tooth of sectional wheel is meshed with the input gear of rapier transmission box, makes the rigid rapier reciprocating motion by sword transmission wheel at last.At this moment the direction of rotation of the direction of rotation of sectional wheel and sword transmission wheel is perpendicular.This kind mechanism complexity, drive disk assembly is many, and consumed energy is big, and need occupy bigger space.
The deficiency that exists for the shortcoming that overcomes above rigid rapier weft insertion mechanism device and prior art promptly is a purpose of the present utility model.
Summary of the invention
The utility model is for solving the above technical problem that exists in the known technology, and provide a kind of Flexible Rapier in Inserting Weft device of belt carcass loom, the technical scheme that the utility model is taked is: comprise loom main shaft 9, wallboard 6, slay 15 and reed 13, by belt wheel support 3, constant diameter cam 10, rack bar 1, gear shaft 7, sword belt wheel 2, sword belt 4, sword head 5, twizzle 14, sword belt storehouse 12, the location is adjusted cover 16 and is formed, it is characterized in that rack bar 1 bottom is provided with rectangular groove 1a, rotor hole 1b, sword belt wheel 2 is provided with gear teeth 2a, sword belt 4 is provided with sword belt and takes turns a plurality of oblong aperture 4a that 2 phase shift cooperate, constant diameter cam 10 end faces are provided with through hole 10a, the location is adjusted cover 16 and is provided with open trough 16a, platform 16b, deck hole 16c, screwed hole 16d, side screwed hole 16e, constant diameter cam 10 is housed on the loom main shaft 9, driving rack bar 1 by the rotor on the rack bar 1 11 moves up and down along gathering sill seat 8, tooth driving gearshaft 7 on the rack bar 1 drives sword belt and takes turns 2 forward and reverse rotations, sword belt wheel 2 drives sword belt 4 again and sword head 5 back and forth moves horizontally, sword belt wheel 2 is installed on the loom side 6 by belt wheel support 3, and sword belt storehouse 12 is fixed on belt wheel support 3 and the loom side 6.
The utility model has also adopted following technical measures: the constant diameter cam 10 that contains the circular curve characteristics of motion is set, uses bolt and location adjustment cover 16 to cooperate to adjust and fix; Sword belt 4 is a flexible material, and an end and sword head 5 are connected to a fixed; Sword belt 4 be installed on the loom block 15, a plurality of staggered in opposite directions and be parallel to Loom reed 13 and move in the middle of the guide hook 14 arranged.
Advantage that the utlity model has and good effect
It is convenient that the utility model is tied simple Installation and Debugging, saved equipment investment and improved production efficiency.

The specific embodiment
Understand content of the present utility model, characteristics and effect for further, and conjunction with figs. 1 is described in detail as follows:
At first should make the debugging that corresponding parts are assembled then accordingly by drawing and specification requirement.Its emphasis describes in detail: the beating-up mechanism that comprises because of the belt carcass loom is a separate type, also is unidirectional wefting insertion simultaneously, and used weft insertion device is not swung with slay, so belt wheel support 3 is packed on the wallboard 6.Gear shaft 7 is contained on the belt wheel support 3 by double-row bearing and bearing block, and at this moment gear shaft 7 can be with respect to 3 rotations of belt wheel support.One end of gear shaft 7 has profile of tooth, and the other end has ladder, utilizes the screw of the location and the side of ladder side, utilizes four screws that sword belt wheel 2 is fixed together with gear shaft 7 by being incorporated in sword belt wheel 2 and joining of gear shaft the outside ring flange that uses of sword belt wheel.The rotation of gear shaft comes transmission by rack bar 1.Tooth is arranged at the top of rack bar 1, and two rotors that match with constant diameter cam that centre-to-centre spacing is constant are equipped with in the bottom, has an elongated slot 1a on the rack bar 1 of two rotor centres, and loom main shaft therefrom passes.Move by the above-below direction of constant diameter cam 10 driving rack bars 1 along gathering sill seat 8 regulations when main shaft 9 rotates, the driving gearshaft 7 final sword belt wheels 2 that drive rotate.
The location of constant diameter cam 10 utilizes a location to adjust cover 16, this cover has an open trough 16a along the circular hole direction, one side of groove has screw, opposite side is established platform and through hole, by the effect of screw, make open trough 16a slit diminish, positioning sleeve is held main shaft tightly and is positioned, and constant diameter cam links together by screw and location adjustment cover, can regulate easily.
When sword belt wheel 2 rotation drive sword belts 4 moved, the twizzle 14 that is installed on the slay 15 by relative interlaced arrangement led, and guarantees wefting insertion reliably.Sword belt 4 is stored among the sword belt storehouse 12 that is installed on belt wheel support 3 and the wallboard 6 after sword head 5 is return.
