Abstract

The invention discloses a heat sealing knife device, which comprises a fixed frame, a sealing knife assembly, a heating and heat preservation assembly and a pressurizing assembly. The sealing knife assembly includes a sealing knife and a sealing knife lifting module, and the sealing knife lifting module is fixed On the fixed frame, the sealing knife lifting module drives the sealing knife to lift; the heating and heat preservation component includes a heating module and a heat preservation module, the heating module is connected with the sealing knife, and the heating module The group heats the sealing knife, the heat preservation module keeps the sealing knife warm; the pressurizing component applies pressure to the sealing knife, so that the sealing knife seals the PE plastic bag. The sealing knife of the invention heats up quickly, the temperature is stable and not easy to lose, the temperature recovery after heat sealing is accelerated, and the temperature of the sealing knife can be monitored at all times, the heating time can be controlled, the pressure is stable and controllable, and the heat sealing quality is high.

Description

technical field [0001] The invention relates to the field of heat sealing welding equipment, in particular to a heat sealing knife device. Background technique [0002] PE (Polyethylene) plastic bags are mainly composed of high-molecular organic compound polyethylene. PE plastic bags are widely used in medical device packaging, medical product packaging, sterile product packaging, dust-free product packaging, electronic industry parts packaging, semiconductor packaging, optical Various industries such as instrument packaging, hard drive packaging and leveling packaging. PE plastic bags are sealed in two forms: hot-press sealing and cold-sealing. Hot-press sealing is used to seal PE plastic bags, which has requirements for sealing knife temperature, heating time and pressure. In particular, PE plastic bags for medical use need to be kept sterile until the packaging bag is opened. The packaging bag must not have the chance of being invaded by air pollution, dust, microorganis...
