Abstract

A simple overturn-preventive adjusting device relates to the metal processing field and is composed of a belt (1), a roller, an adjusting screw (4), a spring (9), a shaft sleeve, and a swing arm. By virtue of mounting the adjusting screw (4) and the spring (9) on the swing arm and rotating the adjusting screw (4) and the spring (9) on the swing arm, the problem that the swing arm of a mechanical type embracing device is easy to overturn excessively is solved. The simple overturn-preventive adjusting device is strong in practicality and relatively convenient to mount, maintain, and operate. Not only can the swing arm be prevented from excessive overturn when the embracing device is in the open state, but also the compaction degree of the roller (2) with respect to an embraced object (15) can be adjusted in the embracing state. Therefore, the production requirement is satisfied and the equipment security and production efficiency are improved.
