when turning, the needle is at the needle-setting position, the first roller is lifted, the second roller presses down the envelope, at this time, the envelope is only limited by two points, the needle and the second roller are limited, the motor rotates anticlockwise, the second roller rotates anticlockwise under the transmission of the second synchronous belt, at this time, the second roller drives the envelope to move anticlockwise under the friction force, but as the needle is inserted in the envelope, the envelope can only rotate around the circumference of the needle, the radius is the distance between the needle and the second roller, when the envelope turns a first corner to shield the first detector and the second detector, the motor stops, the first cylinder presses down, the first roller and the second roller press the envelope simultaneously, the motor rotates clockwise to drive the envelope to sew a second edge, the actions before repeating are finished, the second corner, the third corner, the fourth corner and the rest edges, all cylinders lift up to drive the rollers to lift up and leave the envelope, and finishing sewing.
When sewing the great strip of paper used for sealing of thickness difference, because first gyro wheel and second gyro wheel are located same straight line, two gyro wheels can fall simultaneously in thicker department or thinner department, the gyro wheel is in the downhill path state and rotates normally when thicker toward thinner sewing, but be in when thinner toward thicker sewing, two gyro wheels are in the climbing state, it is not smooth to appear to send the cloth, the phenomenon that the gauge needle diminishes, third cylinder pushes down and drives the third gyro wheel rotation this moment, the third gyro wheel is located first gyro wheel and second gyro wheel the place ahead, be in thick position, do benefit to and send the cloth, can assist first gyro wheel and second gyro wheel climbing, solve the phenomenon that the gauge needle is littleer.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
