technical field

The utility model relates to a buffer device for continuous cutting of filter bag strips.

Background technique

At present, in the forming process of filter bag strips, it is necessary to sew or fuse the two sides of the bag cloth along the length direction, then cut to form a bag strip with two ends open, and then use one end of the bag strip as an open bag mouth, The other end is closed to form the bottom of the bag.

Therefore, cutting is also one of the processes. But we all know that since the filter bag strips are processed continuously, the most common cutting method is to stop the filter bag strips, cut them and then continue to run; or through the synchronous movement of the cutter and the filter bag strips, the The cutting of filter bag strips is realized in relative motion.

However, the cutting method adopted by the former not only affects the work efficiency, but also shortens the service life of various electrical components due to repeated startup and shutdown; the cutting method adopted by the latter can realize cutting without stopping , but in order to make the cutting tool move synchronously, the complexity of the equipment structure is caused, which directly increases the cost of cutting the filter bag strips.
