Description

Circular knitting machine transmission structure

The utility model relates to a transmission structure of a circular knitting machine, in particular to a transmission structure of a circular knitting machine which has a more compact component, a faster assembly, a lighter overall weight, and can reduce the power required for operation and has an energy-saving effect.

According to the general circular loom, it can be used for automatic and rapid production of woven bags. The principle of the circular loom is mainly to drive the upright type jumper arranged in a ring shape by the transmission device, so that the warp on the jumper is actuated and used. The drive shuttle drives the weft thread to continuously patrol the warp between the upper and lower movements to form the upper and lower cross weaving to complete the weaving bag operation.

For example, the TW 415919 Taiwan Patent Case is a patent case filed and approved by the applicant. The case is mainly based on the machine with a main power wheel and two intermediate wheels. The main power wheel is connected with the two intermediate wheels. The intermediate wheel is respectively meshed with the passive wheel, whereby the power can be transmitted to the intermediate wheel via the main power wheel, then transmitted to the passive wheel by the intermediate wheel, and finally driven by the passive wheel to drive the ring on the machine. The group is actuated, and the two movable links assembled by the combination of the upper and lower crankshaft links are reciprocated up and down to perform the weaving.
