Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a ribbon weaving machine. Background Technology

[0002] A ribbon weaving machine is a device used to produce various types of ribbons. Its structure mainly consists of multiple sets of hem frames that drive the warp yarns to move up and down to form openings, and the weft yarns are woven by moving weft through the openings.

[0003] When using a ribbon weaving machine, the pattern plate chain is usually arranged manually, and the rocker arm drives the warp yarns on the frame to move up and down to achieve different ribbon patterns. However, the pattern changes are limited and the cycle is short, which is far from meeting the needs of the current ribbon weaving industry. In addition, the need for manual operation increases the time and labor costs considerably.

[0004] Currently, most ribbon looms on the market use a swing arm to reciprocate and move the warp yarns on the frame up and down. One end of the swing arm is hinged to the frame, and the other end is linked to the frame. A transmission mechanism is set below the swing arm, which includes an extension roller, a sprocket, and a patterned chain that works with both. The two ends of the patterned chain are respectively fitted onto the extension roller and the sprocket. The patterned chain consists of several chain plates. The movement trajectory of the swing arm is controlled by the shape of the chain plates, which extends the frame travel to three positions: upper, middle, and lower. However, the pattern cycle is short, the pattern complexity is limited, and the adjustment time is long. Utility Model Content
