Groove for automatically adjusting viscosity of PVC material

The utility model belongs to the field of production of polyvinyl chloride (PVC) gloves, and in particular relates to a groove for automatically adjusting the viscosity of a PVC material. The groove comprises a groove body, wherein a viscometer is arranged on the inner wall of the groove body and is connected with a control system; a plurality of material storage devices which are provided with the PVC materials with different viscosity are arranged above the groove body; and sensors are arranged on material inlet valves of the material storage devices and are connected with the control system. A viscosity signal detected by the viscometer is transmitted to the control system, and the sensors on the material inlet valves are controlled by the control system, so that proper PVC materials are added into a PVC material groove according to actual conditions, the viscosity of the PVC material is detected and adjusted timely, and the aim of effectively controlling the gram weight of the PVC gloves is fulfilled.
