Hose core stripping machine integrates the five stations of cutting, ring cutting, core cutting, core stripping, pressure test and water blowing in one. A complete set of closed loop process flow from the separation of the shaft core and the hose to the pressure holding test of the hose is realized to ensure the production of qualified and stable products. Core blowing station: the cylinder and core blowing die are used to locate the hose, and the shaft core is blown out by pressure water; Pressure test station: the use of PLC and detection components to achieve accurate control of pressure and pressure holding time; Water blowing station: The residual water in the empty pipe is blown out by compressed air. The equipment integrates precise PLC control, humanized touch screen operation and high-precision pressure detection elements. It can not only select different pipe diameters, different pressures and different pressure holding times through the touch screen, but also store and trace the product test results.
