Problems solved by technology
When the length of the sewing machine exceeds 8 meters, since the transmission points of the machine head on both sides of the machine are far away from the position of the transmission belt, the distortion of the transmission shaft is very large. At the same time sequence, the needle bar of the machine head is in the vertical direction The difference in position, especially when the machine is running at high speed, the relationship between the needle and the shuttle of the machine cannot be synchronized
Therefore, there is a high thread breakage rate in the super-long sewing machine, and it can only be operated at a low speed of 500-650 revolutions per minute, and the sewing efficiency is very low.

The invention discloses a multi-shaft synchronous driving structure of a sewing machine. The multi-shaft synchronous driving structure comprises a main beam with certain length arranged on a frame, a front shaft and a back shaft. The front shaft and the back shaft are respectively mounted to the front and the back end of the main beam by means of bearing seats. Multiple openings, at equal intervals, are arranged on the main beam in a penetrating mode side by side. Multiple synchronous belts are arranged between the front shaft and the back shaft side by side. Each synchronous belt penetrates through a corresponding opening of the main beam and is wound between the front shaft and the back shaft. Each synchronous belt is provided with a tension device. The front shaft is in drive joint with multiple machine head working shafts. The middle portion of the back shaft is in drive joint with a motor. The multi-shaft synchronous driving structure of the sewing machine has following beneficial effects: the problem that a driving shaft of a conventional sewing machine has different deflection angles at different sewing positions is solved; and by the mode of adding a second-stage driving rod, errors for upper and lower positions of a sewing needle are reduced in order to improve sewing efficiency and quality.
Description
technical field [0001] The invention relates to a sewing machine, in particular to a double-shaft multi-synchronous transmission structure of the sewing machine. Background technique [0002] Existing sewing equipment on the market usually adopts a belt to drive the working shaft of the machine head to work through side transmission or intermediate transmission. When the length of the sewing machine exceeds 8 meters, since the transmission points of the machine head on both sides of the machine are far away from the position of the transmission belt, the distortion of the transmission shaft is very large. At the same time sequence, the needle bar of the machine head is in the vertical direction The difference in position, especially when the machine is running at high speed, the relationship between the needle and the shuttle of the machine cannot be synchronized. Thereby, there is a high rate of thread breakage in the super-long sewing machine, which can only be operated a...
