Abstract

The utility model relates to a simplified weft selecting device for a rapier loom. A deflector rod 6 is connected with one end of a connecting rod 16, the other end of the connecting rod 16 is directly connected with the tail end of a rocking arm 2, and one end of a return spring S3 of the rocking arm 2 is directly connected with the middle part of the rocking arm 2. Compared with the original parts, the parts of the utility model are reduced by one quarter; the connecting points are reduced to one half of the original connecting points. The accumulated error of the action of members is reduced by the structure, the motion precision of weft selecting fingers is increased, and the workload of the corrective maintenance of the weft selecting device is reduced.

Description

Simple and easy Rapier looms weft-selecting mechanism

One, technical field

The utility model relates to a kind of color selecting apparatus of weaving loom, specifically a kind of simple and easy Rapier looms weft-selecting mechanism.

Two, background technology

At present, the weft-selecting mechanism of domestic Rapier looms carries out the transition to electronic type by fully mechanical, and electronic type has been improved to two cams of eight look weft-selecting mechanisms configuration from cam of every look weft-selecting mechanism configuration, as Chinese patent ZL97242020.7, it comprise select latitude refer to 1 with select latitude to refer to that 1 connects firmly rocking arm 2 together, cam 5 by the external impetus driving, be controlled by the electromagnet 10 of peripheral control unit and inhale iron 11, inhaling iron 11 is that the oscillating rod type that an end is linked on the support 3 is inhaled iron, each driving lever 6 is sleeved on the same shift lever axis 8, and this shift lever axis 8 places guide chute 9 again.But because its transmission mechanism is by driving lever 6, two connecting rods 16 and 17, fork 14; rocking arm 2 is formed, and its structure is complicated, and linking point is many: as driving lever 6 and connecting rod 16; connecting rod 16 and fork 14; fork 14 and connecting rod 17, and connecting rod 17 is connected with rocking arm 2, therefore; the wear point of loom high-frequency action causing hinged place is also many; the accumulated error that this has not only strengthened mechanism action, has influenced to select latitude to refer to 1 accuracy of working, and has also increased the workload that loom is maintained.

Three, summary of the invention

The utility model is many at electronic weft selection device transmission mechanism complexity, the pin joint of Rapier looms, has influenced and has selected latitude to refer to 1 work accuracy, and the technical scheme of proposition is to overcome the defective that prior art exists, and a kind of simple and easy Rapier looms weft-selecting mechanism is provided.

The technical scheme of the simple and easy Rapier looms weft-selecting mechanism of the utility model is: comprise and select latitude to refer to 1, refer to that with selecting latitude 1 connects firmly rocking arm 2 together, cam 5 by the external impetus driving, be controlled by the electromagnet 10 of peripheral control unit and inhale iron 11, inhaling iron 11 is that the oscillating rod type that an end is linked on the support 3 is inhaled iron, each driving lever 6 is sleeved on the same shift lever axis 8, this shift lever axis 8 places guide chute 9 again, it is characterized in that it comprises that also transmission mechanism is by driving lever 6, compositions such as connecting rod 16 and rocking arm 2 and back-moving spring S3 thereof, driving lever 6 links with connecting rod 16 1 ends, connecting rod 16 other ends are direct and rocking arm 2 tail ends are hinged, and the end of the back-moving spring S3 of rocking arm 2 directly links to each other with the middle part of rocking arm 2.The simple and easy Rapier looms weft-selecting mechanism of this kind has been simplified the transmission mechanism of former weft-selecting mechanism, part is than original minimizing 1/4th in addition, and the pin joint of driving member has reduced half, has reduced the accumulated error of mechanism action, improve the operation precision that selects latitude to refer to, reduced the workload of weft-selecting mechanism maintenance.

Four, description of drawings

Fig. 1 is the electronic weft selection device structure chart of original Rapier looms.

Fig. 2 is the simple and easy Rapier looms weft-selecting mechanism of a utility model topology view.

Among the figure: 1, select latitude to refer to; 2, rocking arm; 19, limited block; 3, frame; 5, cam; 11, inhale iron; 10, electromagnet; 9, guide chute; 6, driving lever; 16, connecting rod; 8, shift lever axis; The S3 back-moving spring.

Five, the specific embodiment

Below in conjunction with Fig. 2 the utility model specific implementation process is described further.

When electromagnet 10 energisings, to inhale iron 11 and be attracted, cam 5 promotes driving lever 6, and driving lever 6 is that fulcrum is swung to the right with the left end of inhaling iron 11, and then moves right by the connecting rod 16 direct lower ends that drive rocking arm 2, makes and selects latitude to refer to that 1 works downwards; When electromagnet 10 outages, to inhale iron 11 and lift, the upper end of driving lever 6 is a free end, and connecting rod 16 is failure to actuate, and selects latitude to refer to 1 akinesia, and the switching electricity of electromagnet 10 is controlled by the loom controller.

Claims

1. simple and easy Rapier looms weft-selecting mechanism, comprise and select latitude to refer to 1, refer to that with selecting latitude 1 connects firmly rocking arm 2 together, cam 5 by the external impetus driving, be controlled by the electromagnet 10 of peripheral control unit and inhale iron 11, inhaling iron 11 is that an end is linked at the swing suction iron on the support 3, each driving lever 6 is sleeved on the same shift lever axis 8, this shift lever axis 8 places guide chute 9 again, it is characterized in that it comprises that also driving lever 6 and connecting rod 16 1 ends link, connecting rod 16 other ends are direct and rocking arm 2 tail ends are hinged, and the end of the back-moving spring S3 of rocking arm 2 links to each other with the middle part of rocking arm 2.
