Abstract
An up-and-down swing mechanism for separated heald frames of a sample fabrics machine, which includes a plurality of heald frames fitted to a sample fabrics machine. A lower end of each of the heald frames is respectively fitted with a clutch and a swing arm, and controlling a portion of the clutches to engage/separate from the swing arms causes two swing arms to swing/not swing, which then drive a portion of the heald frames to enable up and down swing/no swing thereof through two transmission arms, thereby weaving the required fabric according to the style of sample fabric to be produced.
Claims4
An up-and-down swing mechanism for separated heald frames of a sample fabrics machine, comprising:
- a plurality of heald frames fitted to a sample fabrics machine, a lower end of each of the heald frames is connected to a fixed plate, and two sides of the lower end of each of the fixed plates are respectively pivotal located to a transmission arm;
- a master drive, the master drive is fitted within the sample fabrics machine corresponding to positions of the two transmission arms, the master drive is driven by a power device, a swing arm is pivotal located to the master drive, and a clutch is located between the power device and the swing arm, thereby enabling the clutch to engage with or separate from the swing arm to cause up and down swing or no swing thereof,
- a slave drive, the slave drive is fitted within the sample fabrics machine juxtaposed to one side of the master drive, another swing arm is fitted to the slave drive, and semicircular rows of teeth are respectively located on corresponding ends of the swing arm and the other swing arm, the two rows of teeth are disposed to mutually engage, thus, when the swing arm swings, then the other swing arm is actuated and swings in synchronization therewith;
- furthermore, the upper end of one of the transmission arms is pin connected to one side of the lower end of the fixed plate, and the lower end is pin connected to the other end of the swing arm relative to the row of teeth, while the upper end of the other transmission arm is pin connected to the other side of the lower end of the fixed plate, and the lower end is pin connected to the other end of the other swing arm relative to the row of teeth,
- whereby, according to the style of sample fabric to be produced, controlling a portion of the clutches to engage or separate from the swing arms within a period of time causes the two swing arms to swing or not swing, which then drives a portion of the heald frames to cause up and down swing or no swing thereof through the two transmission arms within a period of time, thereby weaving the required style of fabric.
