The invention discloses an automatic sewing device. The automatic sewing device comprises a sewing machine body; the sewing machine body is composed of a first sensor, a second sensor and a control device, wherein the first sensor is used for detecting whether the sewing turning corner of cloth reaches a reducing position, which is away from a needle position at a preset distance; the second sensor is used for detecting whether the sewing turning corner reaches a position corresponding to a machine needle; the control device is connected with the first sensor and the second sensor and also connected with a needle driving device of the sewing machine body, controls the needle driving device to reduce the speed according to signals detected by the first sensor and controls the needle drivingdevice to stop according to signals detected by the second sensor. The automatic sewing device enables the machine needle to automatically stop in position, thereby being capable of reducing labor intensity and ensuring open thread stitch quality. The invention also discloses an automatic sewing equipment comprising the automatic sewing device.
Description
technical field [0001] The invention relates to the technical field of mechanical cutting automation equipment, and more specifically, relates to an automatic sewing device. In addition, the present invention also relates to an automatic sewing device comprising the above automatic sewing device. Background technique [0002] In the process of shirt making, the topstitching of the collar and sleeves is mainly manual sewing. This is mainly because the topstitches of collars and sleeves are multi-segment continuous stitches, that is, there is a corner between two adjacent stitches. Therefore, during the topstitching process, the needle needs to stop at the corner of the stitches In order to adjust the position of the fabric and then sew another stitch. [0003] However, in the prior art, during normal sewing, the needle speed is usually very fast. In order to avoid the needle not being easy to stop due to inertia, it is usually necessary to manually slow down the needle firs...
