Due to its small size, the temperature control is convenient, the preheating time is short, and it is more energy-efficient. The flattening seat 32 can press the welding piece 33 onto the welding seat 31, ensuring the flatness of the zipper and the fabric during welding. The tensioning mechanism 40 tightens the welding piece 33 to ensure that the welding piece 33 does not bend or deform, which is conducive to ensuring the welding quality.

The positioning mechanism 20 can be used to position the zipper, the welding mechanism 30 can be used to weld the zipper and fabric (such as plastic, cloth) together, and the tensioning mechanism 40 can keep the welding part 33 in a tensioned state at all times to ensure that the welding machine does not deform. During welding, only the welding part 33 generates heat. The size of the mechanism is small, the temperature control is very convenient, the heating is faster, and it is more energy-efficient. At the same time, the flattening seat 32 can press the welding part 33 onto the welding seat 31, so that the zipper and the fabric can fit flatly. The tensioning mechanism 40 tightens the welding part 33, so that the welding part 33 is always in a tensioned state, there is no bending deformation, and the welding quality is guaranteed. Preferably, the welding steps of the zipper welding machine are as follows: 1. Put the zipper into the zipper positioning device 220, and then press the welding edge positioning frame 210 downward so that the welding edge of the zipper and the fabric is pressed against the welding seat 31. 2. The flattening seat 32 and the welding piece 33 move toward the welding seat 31 together, and the heated welding piece 33 welds the edges of the fabric and the zipper together smoothly. 3.
