Abstract

The invention discloses improvement on a bag making machine capable of continuously sealing bags. Primarily, a roll shaft and a rotating shaft are arranged on the bag making machine; the rotating shaft is provided with a sealing knife assembly consisting of a heater, a bracket and a sealing knife; compressed gas is heated by the heater and then is sprayed out by a sealing knife port; continuous sealing can be realized after a thin film passes through the roll shaft; plastic bags of any length can be manufactured; since the hot-gas sealing knife is not directly contacted with the roll shaft and the plastic bag, scratches or stripping of printing ink is not caused on the surface of the plastic bag; and the compressed gas has certain impact force, so that hot gas sprayed out by the sealing knife port can quite firmly seal thicker plastic bags.

Description

technical field [0001] The present invention relates to an improved invention of a bag-making machine, in particular to an improved invention of a heat-sealing knife for continuous heat-sealing of films on the bag-making machine. Background technique [0002] Due to the wide use of plastic bags, for example, the use of plastic bags such as European-style baby diaper bags, rope-through plastic garbage bags and DHL express bags is very widely used and very light. [0003] At present, the existing bag making machine seals the side of the film with a longitudinal sealing knife, seals the secondary film with the main film, and then seals and cuts the side of the film with a 90-degree sealing knife to make a bag. The length of the sealing film is limited by the length of the sealing knife and cannot be used more flexibly. Since the length of the plastic film is limited by the length of the sealing knife, there is a considerable limitation in use. The existing bag body Firstly, a ...
