[0002] A bag making machine is a machine for making various non-woven fabric packaging bags or other material packaging bags. Its processing range includes non-woven fabric or other material packaging bags of various sizes and thickness specifications. Generally, non-woven fabric packaging bags are the main products. During the bag making process, the non-woven fabric packaging bags and other material packaging bags need to be ultrasonically sealed or heat sealed.

[0003] The existing bag making machine sealing stations mainly adopt the following two methods:

[0004] First, seal first and then cut. There are problems that the cutting position after sealing is inaccurate, and a relatively wide cutting size needs to be left at the cutting position, wasting materials;

[0005] Second, an integral sealing and cutting die. There are problems that the cutting edge of the die is not durable and there are burrs in the cutting effect. After the cutting edge is worn, the whole set of die needs to be replaced, thus increasing the production cost and wasting materials.

[0006] Both of the above two methods currently have relatively large drawbacks, and this patent is designed to solve the above problems. Content of the Utility Model

[0007] The utility model provides a replaceable blade split sealing and cutting die to solve the problems in the background technique.

[0012] Further, the countersunk holes on the front mold correspond one-to-one with the threaded holes on the rear mold, and the length of the front mold is the same as the length of the rear mold.

[0013] Further, the head end of the hexagon socket head bolt sequentially passes through the countersunk hole and the mounting hole, and is threadedly connected to the threaded hole.

[0014] Compared with the prior art, the present utility model provides a replaceable blade split sealing and cutting mold, which has the following beneficial effects:
