Abstract

A knitting machine for clothing has a needle module with a plurality of needle units. Each of the needle units has a needle hook and a plurality of protrusions. The machine also has a first actuation module with a carriage that has a track to connect to one of the protrusions. The carriage can move left and right, and this movement moves the needle units in a longitudinal direction. The machine also has a second actuation module with a connector that has a screw thread to mesh with another one of the protrusions. The connector can move up and down, and this movement moves the needle units.

First claim

The invention claimed is:

1. A knitting machine for clothing, comprising:
a needle module in which a plurality of needle units are arranged side by side, each one of the plurality of needle units comprising:
a main body,
a needle hook formed in an end portion of the main body, and
a plurality of protrusions formed in a middle region of the main body;

a first actuation module comprising a carriage, a rear of the carriage being formed with a track to be linked with a first protrusion of a selected needle unit of the plurality of needle units, and the carriage being provided to be movable left and right;
a second actuation module comprising a connector formed with a screw thread for meshing with a second protrusion of the selected needle unit, and an actuator for actuating the connector to move, and the connector being provided to be movable left and right;
a first movement unit allowing the first actuation module to move up and down to be in contact with the needle module; and
a second movement unit allowing the connector of the second actuation module to move up and down with respect to the needle module,
wherein, when the first protrusion of the selected needle unit is linked to the track as the first movement unit moves the first actuation module toward the needle module, the selected needle unit moves in a longitudinal direction of a main body of the selected needle unit by a connection between the track of the carriage and the first protrusion of the selected needle unit as the carriage moves left and right, and
wherein, when the second movement unit moves the connector of the second actuation module toward the needle module, the selected needle unit meshing with the screw thread that moves in the longitudinal direction of the main body of the selected needle unit as the actuator actuates the connector to rotate while the screw thread is connecting with the second protrusion of the selected needle unit.

2. The knitting machine for clothing according to claim 1 , wherein the connector is one of a plurality of connectors which are arranged side by side, wherein the plurality of connectors are fewer than the plurality of needle units.

3. The knitting machine for clothing according to claim 1 , wherein the actuator of the second actuation module is rotatable clockwise and counterclockwise, and comprises an encoder to sense a rotation number of the actuator.

4. The knitting machine or clothing according to claim 1 , wherein the first actuation module and the second actuation module are provided to reciprocate together in a direction crossing the longitudinal direction of the main body.

5. The knitting machine for clothing according to claim 1 , wherein the second movement unit is actuated by a solenoid valve.
