Abstract
The invention relates to a crank rocker weft insertion mechanism for a rapier loom. The crank rocker weft insertion mechanism consists of a crank, a rocker, a giant swing, a connecting rod, a sector gear, a driving plate shaft, a rapier band and a rapier head, wherein the crank is fixed on a main shaft and is connected with the rocker; the rocker is connected with the giant swing; the connecting rod and the giant swing are connected with the sector gear; the driving plate shaft is meshed with the sector gear and is connected with the rapier band and the rapier head. By the weft insertion mechanism, the weft insertion speed of the rapier loom is improved, so that the rotation speed of the loop can be improved, and the weaving speed can reach 500 to 700 revolutions/minute; and the crank rocker weft insertion mechanism is compact in structure, simple in parts and low in manufacturing cost.
Description
Affiliated technical field
The present invention relates to a kind of Rapier looms, particularly a kind of weft insertion device that is consisted of by crank rocker of flexible rapier loom.
Technical background
Flexible rapier loom has the developing history in 60 years till now from invention, the technological progress of Rapier looms is immediately following the progress of industrial level, and at present, Rapier looms has developed into electromechanical integration, intelligentized new high-tech product.Rotating speed develops into present 500～700 rev/mins from initial 50～60 rev/mins, and technological innovation and technological progress are endless.The rotating speed of previous generation flexible rapier loom is 200～350 rev/mins, in order to improve its rotating speed, different trials has been done by each company, but the further raising of its rotating speed is subject to the restriction of its general structure, especially it is impossible that the restriction of weft insertion device, rotating speed are brought up to 500～700 rev/mins.So must design and a kind ofly be more suitable for high-revolving weft insertion device and replace old weft insertion device.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of crank rocker weft insertion device that can effectively increase Rapier looms rotating speed and compact conformation.
Technical scheme of the present invention is a kind of crank rocker weft insertion device of flexible rapier loom, by crank, rocking bar, put on, connecting rod, sector gear, driver plate axle, sword belt and sword head form, crank is fixed on the main shaft, crank connects rocking bar, rocking bar connects to be put on, connecting rod is connected with putting on sector gear, driver plate axle and sector gear engagement, and the driver plate axle is connected with sword belt and sword head.
The operation principle of this weft insertion device is that crank rotates under the driving of main shaft, drive rocking bar and do spatial movement, the rocking bar motion drives to put on does swing, connecting rod is connected with putting on sector gear, connecting rod passes to sector gear to the swing of putting on, reciprocating rotation is done in driver plate axle and sector gear engagement, drives sword belt and sword head and does linear reciprocating motion, reaches the purpose of wefting insertion.
The invention has the beneficial effects as follows: compare with the wefting insertion sword head motion of previous generation loom, under identical loom rotating speed, speed, the acceleration peak value of this mechanism are little, so be more suitable for the high-speed motion of sword head.And this mechanism is simpler than weft insertion device compact conformation, the part of previous generation loom, manufacturing expense is low.
For complete machine, after this nested structure development and Design is finished, reached desirable effect through test.This crank rocker weft insertion device has following advantage:
1, improved the loom filling insertion rate, and then can improve the rotating speed of loom, weaving speed can reach 500～700 rev/mins;
2, compact conformation, part is simple, low cost of manufacture.
Description of drawings
Fig. 1 is the structure diagram of crank rocker weft insertion device.
Fig. 2 is A-A revolved sectional view among Fig. 1.
Fig. 3 is the kinetic characteristic figure of crank rocker weft insertion device wefting insertion sword head.
Among the figure, 1 crank, 2 rocking bars, 3 put on, 4 connecting rods, 5 sector gears, 6 driver plate axles, 7 sword belts and sword head.
The specific embodiment
As Figure 1-3, a kind of crank rocker weft insertion device of flexible rapier loom, by crank 1, rocking bar 2, put on 3, connecting rod 4, sector gear 5, driver plate axle 6, sword belt and sword head 7 form, crank is fixed on the main shaft, crank connects rocking bar, and rocking bar connects to be put on, and connecting rod is connected with putting on sector gear, driver plate axle and sector gear engagement, the driver plate axle is connected with sword belt and sword head.
This kind crank rocker weft insertion device specific works process is: the crank 1 that is fixed on the main shaft rotates under the driving of main shaft, drive rocking bar 2 and do spatial movement, rocking bar motion drive is put on 3 and is done swing, connecting rod 4 is connected with putting on to be connected with sector gear, connecting rod 4 passes to sector gear 5 to the swing of putting on 3, driver plate axle 6 is done reciprocating rotation with sector gear 5 engagements, drives sword belt and sword head 7 and does linear reciprocating motion, reaches the purpose of wefting insertion.Sword head speed when entering shed open and withdrawing from shed open is maximum, and the advance and retreat motion of sword head is symmetrical.
