In the above structure, the upper roller 95 is an idler and does not have the function of actively pushing and feeding. The lower roller 951 is driven by another gear 952 driven by the belt pulley (not shown in the figure), so that the upper roller 95 drives the working material to be rolled and fed. , but the upper and lower rollers 95, 951 cannot adjust their abutment positions or make them relatively close to the pressure roller 93 as much as possible to reduce wrinkles, and the pulley drives the gear 952 and the lower roller 951, which will also be caused by belts and gears. Abrasion produces mechanical damage, which causes the rolling and feeding to lag or slip. Therefore, the welded working materials are prone to wrinkles and unevenness. Moreover, for thicker working materials or two different thicknesses, it is different from the upper and lower parts. The rollers 95 and 951 produce relatively large or uneven frictional forces, which will affect the flatness of the welding work pieces. At the same time, the pushing and pulling of the welding machine will not be smooth, which will affect the quality and bonding effect of the finished product.
