The setting of protection portion makes the protection shield can play the effect of protection to the output, reduces and prevents even that external to the interference of output from making the output remove smoothly, reduces the fault rate to improve and paste a strip efficiency.

In the above-mentioned strip cutting device for sewing machine, the back of the protection plate facing the sewing platform is fixedly connected with an air suction joint which is arranged along the fixed plate in an inclined upward direction. The air suction joint is externally connected with an air suction pipe, and the thread ends and fragments can be sucked away through the air suction joint; the air suction joint is attached to the fixing plate, so that the space is reasonably utilized.

In the above device for cutting off the stick of the sewing machine, the driving member is a driving cylinder or an electromagnet.

In the above device for cutting off the welt of the sewing machine, the front end of the machine head is fixedly connected with the inductor. The inductor is the light eye, calculates the distance that the strip moved through the light eye, sends this signal and control driving piece work, makes the cutter cut off the strip, improves automatic efficiency to improve strip efficiency.

Compared with the prior art, the utility model provides a pair of sewing machine pastes strip cutting device has following advantage:

1. the cutting device automatically cuts off the strip, so that the sewing machine can continuously sew the strip without stopping the machine, thereby improving the strip sticking efficiency and the processing efficiency.

2. The cutting device reasonably utilizes space, so that the cutting device cannot be clamped when being installed in the machine head, and meanwhile, the cutting effect of the cutting device can be improved.
