The heat-seal belt driving wheels play a very critical role in the existing sealing machine, a pair of heat-seal belt driving wheels are usually arranged on the sealing machine, a driving belt groove matched with the driving belt and a heat-seal belt groove matched with the heat-seal belt are respectively arranged on the circumferential surface of the heat-seal belt driving wheels, and the pair of heat-seal belt driving wheels clamp the heat-seal belt to press and bond the mouth of the film packaging bag and simultaneously convey the film packaging bag forwards. In order to ensure the heat-sealing effect, the groove bottom of the heat-sealing groove is usually arc-shaped with the middle high and two sides low, and in order to prevent the heat-sealing belt from deviating and slipping towards two sides during the working process due to the two sides low, the two sides of the heat-sealing groove are provided with retaining rings slightly protruding, but lower than the part protruding from the middle arc of the heat-sealing groove. Because the plastic film packaging bag is heated by the heating part in the heat sealing process, the plastic film becomes soft, the phenomenon that the plastic film is wound by the driving wheel of the heat sealing belt in a winding manner and is wound on the driving wheel frequently occurs in the conveying process, and particularly when the film packaging bag is made of a thin material, the thin material is particularly prominent, so that the film packaging bag cannot normally work, and meanwhile, a large number of unqualified products are caused. Once the film winding phenomenon occurs, or when the equipment is stopped or overhauled, the heat sealing wheel needs to be separated, the film between the heat sealing wheel and the heat sealing wheel is taken out, and the film is rearranged. However, in the conventional heat sealing mechanism, one of the two heat sealing rollers is fixed and the other is movable. When the heat-sealing wheels are separated, only the movable wheel leaves the film, and the other fixed heat-sealing wheel does not leave the film. Because the heat-sealing wheel is powered off, the film is continuously baked by the residual heat, the film is easily deformed, and the film is adhered to the heat-sealing wheel after being melted even if a fire disaster happens in serious cases, so that the film is required to be further improved.
