no. 1 Embodiment

[0088] Such as figure 2 As shown, the sewing machine 1 of the present invention also has a platform 18 arranged horizontally, and the platform 18 is used to place the cloth 4 to be sewed. As mentioned above, the motor 13 of the sewing machine 1 is mainly installed in the main shaft 14 of the sewing machine, and the main shaft 14 of the sewing machine is connected to the needle bar 21 vertically arranged on the platform 18 through a linkage member (not shown in the figure), and the needle bar 21 is positioned close to the platform. One end of 18 is provided with the sewing needle 22 . When the motor 13 is in operation, it can drive the sewing machine main shaft 14, and the sewing machine main shaft 14 can drive the needle bar 21 and the sewing needle 22 to move up and down, thereby sewing the cloth 4 on the platform 18 through the sewing needle 22.

[0089] Such as figure 2 As shown, the bottom surface of the platform 18 is provided with a cloth feeding dog 19 , and the clo...

Abstract

The invention discloses a sewing machine with an automatic control mechanism and an automatic control method thereof. The sewing machine with the automatic control mechanism is used for sewing cloth and at least has a control unit, an operation interface, a cloth sensing unit, a motor drive unit and a motor. The cloth sensing unit is used for sensing the thickness of the currently sewn cloth. When the thickness of the fabric falls within the threshold value, the control unit receives an instruction from the operation interface and sends a corresponding operation signal to the motor driver, and the motor driver correspondingly controls the rotation speed of the motor according to the operation signal from the control unit. When the cloth sensing unit senses that the thickness of the cloth changes, the control unit automatically generates a deceleration signal and sends it to the motor driver. Excessive speed may damage the sewing machine.

Description

technical field [0001] The invention relates to a sewing machine, in particular to a sewing machine with an automatic control mechanism and an automatic control method for the sewing machine. Background technique [0002] Under normal conditions without special requirements, the sewing machine operator usually operates the sewing machine at the highest speed in order to run the sewing machine at full speed and obtain the highest working efficiency. Under certain circumstances, the operating technician will appropriately reduce the operating speed of the sewing machine so that the sewing machine will not have problems such as damage to the organic parts that will cause the production schedule to stop. [0003] Specifically, when the sewing machine is in operation, the reaction force suffered by the sewing needle when piercing the cloth will increase as the operating speed of the motor increases, and when the thickness of the cloth is thicker, the above-mentioned reaction forc...
