Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments of the present invention.

Referring to fig. 1, the automatic webbing embroidery tension adjusting system comprises a tension adjusting front cover 10, a support base 20 and a pair of webbing discs 1, wherein the support base 20 is arranged on the inner side of the tension adjusting front cover 10, and the pair of webbing discs 1 are respectively arranged on two sides of the support base 20.

As shown in fig. 1, motor bases 30 are respectively arranged on two sides of the upper end surface of the support base 20, a stepping motor 2 is arranged at the inner end of each motor base 30, a motor transmission shaft 40 is connected to an output shaft of each stepping motor 2, and the corresponding motor transmission shaft 40 is sleeved with the tape weaving disc 1.

In the present embodiment, the stepping motor 2 is a 57-step motor.

In this embodiment, the inner end of the motor base 30 is provided with a pair of optical couplers 3, and the pair of optical couplers 3 is located above the stepping motor 2.

As shown in fig. 1, the inner end of the motor base 30 is connected with a tension adjusting block 4 through a tension adjusting shaft 50, the tension adjusting block 4 is located on the inner side of the pair of optical couplers 3, and a light blocking sheet 5 is arranged at the upper end of the tension adjusting block 4.

In this embodiment, the light blocking sheet 5 acts on the pair of optical couplers 3 to output a signal to the stepping motor 2, so that the stepping motor 2 continuously rotates forward and backward and drives the transmission shaft 40 to rotate forward and backward, thereby completing tension control of the webbing.

In this embodiment, two pairs of first spring washers 60 and two pairs of second flat washers 70 are disposed between the support base 20 and the tension adjusting front cover 10, four pairs of second spring washers 80 and four pairs of second flat washers 90 are disposed between the stepping motor 2 and the motor base 30, and a pair of retaining rings 100 is disposed between the tension adjusting block 4 and the motor base 30.

In this embodiment, the tension adjusting block 4 is connected to the motor base 30 through a pin 110.

In the structure, in the process of ribbon embroidery, when the tension of the ribbon is small, the ribbon drives the tension adjusting shaft 50 to rotate, so that the tension adjusting block 4 deflects downwards around the pin shaft 110, the light blocking sheet 5 swings upwards to block the optical coupler 3 positioned above, the motor transmission shaft 40 of the stepping motor 2 rotates clockwise, and the ribbon is tensioned; when the tension of the mesh belt is too large, the mesh belt drives the tension adjusting shaft 50 to rotate, so that the tension adjusting block 4 deflects upwards around the pin shaft 110, the light blocking sheet 5 swings downwards to block the optical coupler 3 positioned below, the motor transmission shaft 40 of the stepping motor 2 rotates anticlockwise, and the mesh belt is loosened.

It should be noted that the described embodiments of the invention are only preferred ways of implementing the invention, and that all obvious modifications, which are within the scope of the invention, are all included in the present general inventive concept.
