Description

Technical Field

[0001] The utility model relates to a positioning device, and in particular to a metering roller positioning device which can control the position of a metering roller and adjust a predetermined gap between two rollers. Background Art

[0002] In the technical field of impregnation process (or coating process), after the cloth is coated with the coating material, it needs to pass through a metering roller to remove the excess coating material on the surface of the cloth to produce a finished product that meets the predetermined specifications. In a common cloth winding mechanism including a metering roller, a cylinder is usually used as a power source to drive the metering rollers to move relative to each other, thereby adjusting the gap between the two metering rollers, so that the cloth with the coating material on its surface can have a coating material thickness that meets the predetermined specifications after passing between the two metering rollers. However, due to the mechanical characteristics of the cylinder, there may be an error between the actual gap and the expected gap between the two metering rollers. This error will cause a series of problems in the coating process of the cloth, such as cloth extrusion, uneven cloth guiding, or uneven coating thickness, which will affect the smoothness of the production process and may cause defects in the final product.

[0003] Therefore, how to design a metering roller positioning device that can accurately control the position of the metering roller to adjust the predetermined gap between the two metering rollers, thereby solving the technical problems of the prior art, is an important topic studied by the inventor of the present utility model.
