Description

Technical Field

[0001] The utility model belongs to the technical field of sewing machines, and in particular relates to a cloth moving device of a sewing machine. Background Art

[0002] Automatic sewing machine is controlled by computer and equipped with automatic monitoring system, feeding system, automatic sewing start, sewing according to set trajectory, needle stopping, thread cutting and other functions, which can automatically complete certain sewing processes.

[0003] The existing cloth moving device is driven independently along the X-axis (the width direction of the operating table) and the Y-axis (the length direction of the operating table). Usually, driving mechanisms are set on the X-axis and Y-axis respectively. When moving the cloth, it is usually moved step by step (for example, the cloth placing plate is first driven to move along the X-axis direction, and after it moves into position in the X-axis direction, the cloth placing plate is driven to move along the Y-axis). However, after the needle and the rotary shuttle of the sewing machine complete the sewing in sequence, the cloth needs to be moved to the next sewing point immediately, and the sewing work requires frequent changes of points. Therefore, the independent driving devices make the cloth placing plate move more slowly when driving the cloth, and the interval time between two sewing actions is long. Utility Model Content
