[0001] The utility model relates to the field of bonding machines, in particular to a bonding machine heated by a variable frequency electromagnetic system. Background Art
[0002] The working principle of the bonding machine is to place the materials to be bonded on a conveyor belt, which are usually pre-coated with adhesive; then, when the materials pass through the heating area of the bonding machine, the heating system will heat the materials; depending on the type of bonding machine, the heating method can be electric heating, steam heating, electromagnetic heating, etc.; the purpose of heating is to activate the adhesive and increase its viscosity and fluidity; while heating, the pressure system will apply a certain amount of pressure to ensure that the bonded materials are in close contact; the size of the pressure can be adjusted according to the properties of the materials and the bonding requirements; after the heating and pressurization process, the adhesive fully penetrates and solidifies, firmly bonding two or more layers of materials together; finally, the bonded materials are sent out of the bonding machine through the conveyor belt, completing the entire bonding process;
[0003] For example, in clothing manufacturing, when a bonding machine is used to bond interlining to fabric, the heating system melts the hot melt adhesive on the interlining, and the pressure system makes the fabric and interlining fit tightly together, and after cooling, a firm bond is achieved;
