AI Technical Summary

Technical Problem

The existing circular loom's heald belt drive mechanism is easily affected by inertial forces during operation, resulting in high vibration and noise. Furthermore, the high-pair contact between the planar cam and the rocker arm is prone to generating heat and wear, leading to a short service life.

Method used

It adopts a structure of planetary components and connectors. The planetary gears revolve around the input shaft and rotate on their own axis. The heddle belt moves up and down through the connectors, replacing the traditional rocker arm structure to realize power transmission.

Benefits of technology

It reduces vibration and noise, extends the service life of the helical belt and connectors, improves operational stability and load-bearing capacity, and has a compact structure that occupies little space.

Abstract

The utility model discloses a heald belt driving mechanism which comprises a planet assembly and a connecting piece, the planet assembly comprises an input shaft and a planet wheel, the input shaft is connected with the planet wheel to drive the planet wheel to revolve around the input shaft and rotate, one end of the connecting piece is connected to a center shaft of the planet wheel, and the other end of the connecting piece is arranged on a heald belt in a penetrating mode. And the rotating planet wheel drives the heald belt to reciprocate up and down through a connecting piece inserted on the heald belt. The driving mechanism for driving the heald belt to move up and down is arranged into a structure in which the planet wheel assembly is matched with the connecting piece, and the planet wheel assembly is adopted for transmission, so that the heald belt driving mechanism is compact in structure, operation is not easily influenced by inertia force, the heald belt driving mechanism occupies a small space on a circular weaving machine, and power transmission can be efficiently carried out; the bearing capacity is high, the operation stability is high, and vibration and noise can be greatly reduced in the power transmission process through the planet assembly.
