High speed one drag one servo motor inner ear automatic mask machine, is a highly efficient and highly practical model. After the mask body is made in mask cutting machine, the assembly servo inner ear loop welding machine which can automatically complete ear loop welding, mainly includes a mask transfer belt, an ear loop pulling mechanism, an ultrasonic welding mechanism, a mask receiving mechanism. The design concept of this one drag one connection machine: simple and easy to use, automatic mask production, stable and reliable, with good versatility, compatibility, and cost performance. Only one operator is needed to operate the machine.
