Combined tensile force control device for coiled material

Abstract

The invention relates to the technical field of waterproof coiled material production devices, and specifically provides a combined tensile force control device for a coiled material. The combined tensile force control device has the advantages that the mechanical contact like a bearing is saved, and the noncontact detecting mode of a differential transformer is performed, so that lag is nearly not caused, and the response performance is outstanding; in addition, the size is small, thus a small mounting space is needed, and the mounting can be performed in any angle; the detection ranges from a low tensile force to a high tensile force. The combined tensile force control device is characterized in that all sensors are equipped with essential safe explosion-proof structures; the structure is firm and can bear super instantaneous overload; the performance of the tensile force sensor is controlled through a spring bearing and a bearing differential transformer; the differential transformer has high oscillating frequency, so that the accurate tensile force value can be obtained, and the thermal properties are outstanding; the rich product array for detecting from low tensile force to high tensile force is provided, thus the tensile force of the waterproof coiled material can be controlled well, and as a result, the quality of the waterproof material can be ensured.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled material production devices, in particular to a coiled material composite tension control device. Background technique [0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering basis There is no leakage connection between the building and it is the first barrier for the waterproofing of the whole project. It plays a vital role in the whole project. The thickness of the waterproof membrane is an important indicator of the waterproof membrane. In the process of uncoiling or rewinding coils such as film and rubber, the tension of the coils also changes with the change of the coil diameter. At this time, if the tension is not effectively controlled, wrinkling, Bending, thickness changes and other phenomena, t...

[0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering basis There is no leakage connection between the building and it is the first barrier for the waterproofing of the whole project. It plays a vital role in the whole project. The thickness of the waterproof membrane is an important indicator of the waterproof membrane. In the process of uncoiling or rewinding coils such as film and rubber, the tension of the coils also changes with the change of the coil diameter. At this time, if the tension is not effectively controlled, wrinkling, Bending, thickness changes and other phenomena, the coiled material even breaks, and the expansion and contraction of the coiled material caused by the change of tension is the cause of the offset of the printing position, which seriously affects the quality of the coiled material
