Abstract
The utility model relates to a shedding motion mechanism for a rapier loom of cord fabric, which is characterized in that a rotatable power input shaft which is fixed on a casing is connected with a shaft I through a pair of spiral bevel gear pairs which are connected with a shaft key of each spiral bevel gear pair, the shaft I is connected with a shaft II through a driving gear pair and a driven gear pair which are respectively connected to the corresponding shafts through keys, a plurality of cams which rotate with the shaft II are arranged on the shaft II; a rocking arm shaft is parallel with the shaft II, and a plurality of rocking arms are arranged on the rocking arm shaft corresponding to relevant cams; one end of each rocking arm is respectively connected with a tension spring and a connecting rod corresponding to each rocking arm, and the other end of each rocking arm causes a movable roller which is arranged on the end part to be tightly contacted on the outer surface of each cam under the function of the tension spring. The installing mode of the structure can be mutually exchanged with a dobby, and can be universal with other connecting components, such as left rocker arms, right rocker arms, connecting rods, pull rods, heald frames, etc., and common rapier loom types. The utility model has the advantages of less parts, good versatility and low cost, and is used for weaving cord fabric.
Description
Affiliated technical field
The utility model relates to a kind of harness motion mechanism of cord fabric Rapier looms, is specially cord fabric Rapier looms cam shedding mechanism.
Technical background
At present, China's cord fabric loom major part is fly-shuttle loom and some low-grade low speed Rapier loomss.YJ-I type flexible rapier loom is on the basis of Italian import Rapier looms, and through improving a kind of medium-to-high grade Rapier looms of the market owning amount maximum grow up, this type is being weaved aspect the cord fabric still blank.Subject matter is the requirement of its shedding mechanism incompatibility cord fabric product.Former shedding mechanism exists manufacturing cost height, consumable accessory many, defectives such as unstable properties.
Summary of the invention
In order to overcome the problem that above-mentioned technology exists, the purpose of this utility model provides a kind of device mounting means and can exchange with dobbies, can be general with common type with other attaching parts such as left and right sides rocking arm, connecting rod, pull bar, brown frame etc.; Part is few, and versatility is good, the cord fabric Rapier looms cam shedding mechanism that cost is low.
The technical solution of the utility model is: this kind cord fabric Rapier looms cam shedding mechanism, the rotating power input shaft that it is characterized in that being fixed on the housing connects by a pair of spiral bevel gear parafacies that is connected with the place axle key with axle I, axle I is connected the driving gear, the driven gear parafacies that are arranged on its corresponding axis with axle II by key respectively and connects, and an II is provided with the cam of multi-disc with axle II rotation; Rocker arm shaft is parallel with axle II; corresponding corresponding cam is provided with the multi-disc rocking arm on the rocker arm shaft; an end of rocking arm connects corresponding tension spring and connecting rod respectively, and the other end abuts against on the cam outer face moveable trolley that is arranged on this end under the effect of tension spring.
The beneficial effects of the utility model are that mounting means can exchange with dobbies, can be general with common type with other attaching parts such as left and right sides rocking arm, connecting rod, pull bar, brown frame etc.; The utility model part is few, and versatility is good, low cost of manufacture.
For complete machine, after cord fabric Rapier looms development and Design is finished, reached desirable effect through test.This cord fabric Rapier looms has following advantage:
1, loom rotating speed height: maximum speed reaches 340 rev/mins at present, exceeds more than 1/2nd than existing similar cord fabric loom;
2, loom high efficiency: loom is easy to operate, dependable performance, and fault is few, and start efficient can reach more than 98%, improves 15% than existing similar cord fabric loom;
3, loom is changed fabric variety conveniently: can adjust the filling density size of manufacturing and the width of reed width easily;
4, use cost is low: reasonable in design, and few easy workout part, long working life, easy to maintenance, most mechanisms realize non-maintaining, use cost significantly reduces.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the A-A expanded view of Fig. 1.
Among the figure, 1 is small spiral bevel gear, and 2 is big spiral bevel gear, and 3 is axle I, and 4 is driving gear, and 5 is driven gear, and 6 is axle II, and 7 is cam, and 8 is rocking arm, and 9 is tension spring, and 10 is roller, and 11 is connecting rod, and 12 is power input shaft.
The specific embodiment
As Fig. 1, shown in Figure 2, the concrete structure of this kind cord fabric Rapier looms cam shedding mechanism is: the rotating power input shaft 12 that is fixed on the housing is connected by a pair of large and small spiral bevel gear pair 2,1 that is meshed that is connected with the place axle key with axle I3.The axle I3 with the axle II6 by bearing fixing on housing; Axle I3 is connected the driving gear 4, the driven gear 5 that are arranged on its corresponding axis with axle II6 by key respectively and is connected, and an II6 is provided with the cam 7 of multi-disc with axle II rotation; Rocker arm shaft is parallel with axle II; corresponding corresponding cam is provided with multi-disc rocking arm 8 on the rocker arm shaft; an end of rocking arm 8 connects corresponding tension spring 9 and connecting rod 11 respectively, and the other end abuts against on cam 7 outer surfaces moveable trolley 10 that is arranged on this end under the effect of tension spring.
Working method is to drive axle I3 by power transmission shaft through a pair of large and small spiral bevel gear 2,1 from the power that power output shaft 12 transmits, axle I3 drives axle II6 by driving gear 4, the driven gear 5 of pair of meshing, axle II goes up multi-disc cam 7 and rotates, multi-disc rocking arm 8 makes its upper roller 10 be close to cam 7 by corresponding tension spring 9 effects respectively, rotatablely moving of cam become the swing of rocking arm 8, and rocking arm 8 drivening rods 11 are realized the reciprocating motion that shedding mechanism needs.
Cam 7 and rocking arm 8 are through well-designed and process practical proof, can guarantee that running is steady under fast state, and its intensity also is much higher than at present general shedding cam mechanism, good reliability.This mechanism uses the spring return, and the cam required precision is reduced, and is convenient to processing and manufacturing.This mechanism structure is simple and practical, and working stability is reliable, is suitable for running up.This mechanism not only is exclusively used in plain weave and weaves, through more gear changing and cam can be realized twill-weave and twist the line tissue and weave.
