Problems solved by technology

[0004] In mechanical design, if it is necessary to make the follower move according to a certain motion law, a cam mechanism is generally used to realize it. However, the traditional cam mechanism can only realize the straight motion or swing of the follower, which is difficult to meet the diverse production requirements of modern looms. At the same time, the traditional process is easy to cause yarn breakage and weft yarn breakage, which affects the manufacturing quality and efficiency

Embodiment Construction

[0013] The heald lifting arm of the present invention moves with the eccentric disc, the disc-shaped connecting rod is looped on the eccentric disc, and the eccentric disc interacts with the driving disc through the control hook.

[0014] The driving disc is assembled on the spline shaft by spline connection, and the rotation law of the spline shaft is determined by the slider mechanism. Control the movement law of the heald lifting arm; the swing arm moves up and down under the action of the conjugate cam, driving the iron absorbing arm to move up and down. When the iron-absorbing arm moves upward, the iron-absorbing arm moves closer to the electromagnet. If the electromagnet is not magnetic, there will be no contact between the two. The iron-absorbing arm has a period of rest at the highest point, so that the electromagnet can absorb the iron-absorbing arm 1) If the electromagnet attracts, when the iron-absorbing arm resists the left angled rod and moves downward, the left a...

Abstract

The invention relates to a heald selecting control mechanism of a dobby transmission cam. In the heald selecting control mechanism, a heald lifting arm moves along with an eccentric disc, a disc-shaped connecting rod movably sleeves the eccentric disc, the eccentric disc and a driving disc interact through a control hook, and whether the heald lifting arm moves along with the eccentric disc or notis controlled by the heald selecting control mechanism. The new mechanism for converting constant-speed-rotation input movement into coaxial-rotation variable speed outputting is provided and designed, is compact in structure and stable in output, has good kinematic performance, and is particularly suitable for being applied to a high-speed-rotation dobby.

Description

technical field [0001] The invention relates to a selection control mechanism for a transmission cam of a dobby, belonging to the technical field of textiles. Background technique [0002] With the improvement of living standards, people have a greater demand for clothing fabrics with more complex patterns, and the dobby shed loom perfectly solves this problem. The dobby is an important part of textile machinery and has an important impact on improving textile efficiency and quality. High-speed rotary electronic dobby is the most advanced type of dobby, and it is widely used in high-speed textile weaving with its ingenious structural design and advanced manufacturing technology. The operating mechanism of the high-speed rotary dobby is a cam-slider pendulum-rod combination mechanism that can realize the conversion of uniform-speed rotary input motion into coaxial variable-speed rotary output-rotary speed change mechanism. This mechanism needs to have good kinematic perfo...
