During the operation of the PP yarn string wound filter cartridge making machine, the mixed material is usually placed in a hopper, and the material is conveyed to the extrusion barrel through the feeding screw in the feeding screw barrel, and is extruded outside the screw barrel. A heating coil is arranged, and the rubber powder is melted under the action of the heating coil, and is extruded through an extrusion screw, and the PP yarn of the corresponding size and shape is extruded around the filter in the head.
The setting of the feeding screw and the feeding screw in the production line of the PP yarn string wound filter cartridge making machine makes the mixing of the raw materials more uniform, and the groove depth of the melting section screw in the extrusion screw is shallower and deeper in the extrusion direction, maintaining the intergranularity. The gap is used to achieve a better filtering effect, and the process is simple and the work efficiency is high.
In the composition of the new PP yarn string wound filter cartridge making machine production line, the cooling forming device comprises a cooling water jacket, the cooling water jacket is arranged at the discharge end of the machine head, the water in the cooling water jacket cools the filter core, and the filter element passes through the cooling water jacket. When there is a certain resistance, the pressure of the machine head is increased, and the change of the pressure of the machine head causes the density and strength of the filter to change. Therefore, the pressure of the head can be changed by adjusting the length of the cooling water jacket, and the production is required. A filter with a certain degree of compactness and strength.
