Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] Please refer to Figures 1-4 The present application provides an embodiment:

[0023] A kind of four fluorine material preforming mould for special-shaped pipe lining, including first mounting ring seat 1, the surface of first mounting ring seat 1 is movably connected with second mounting ring seat 2, first mounting ring seat 1 and second mounting ring seat 2 are fixedly connected with half ball cover 3 at upper and lower ends, the top of half ball cover 3 is fixedly connected with exhaust seat 4, the surface of exhaust seat 4 is provided with filter screen cover 5, the inner bottom wall of half ball cover 3 is fixedly connected with ventilation bottom cover 14, the surface of ventilation bottom cover 14 is provided with ventilation net 15, the back of half ball cover 3 is provided with air guide cover 16, heating air flow is inhaled from back through frame 6, then hot air flow enters exhaust seat 4 along with air guide cover 16, is filtered by ventilation bottom cover 14 and ventilation net 15 of the inner bottom wall of first mounting ring seat 1, and is uniformly flowed upwards, the heating operation of the special-shaped pipe in first mounting ring seat 1 and second mounting ring seat 2 is carried out, and finally is rapidly discharged from the half ball cover 3 and exhaust seat 4 on the surface of second mounting ring seat 2, to realize the more uniform heating operation of special-shaped pipe.

[0024] The back-through frame 6 is fixedly connected to the back of the first mounting ring seat 1. The back-through frame 6 is fixedly connected to the back of the back-through frame 6. A protective net bag 8 is provided at one end of the fan frame 7. A movable cover 9 is provided inside the fan frame 7. A heating unit 10 is provided inside the movable cover 9. A ventilation grille 11 is provided at the center of the front of the fan frame 7. A movable shaft 12 is provided on the surface of the back-through frame 6. A sealing ring 13 is provided between the first mounting ring seat 1 and the second mounting ring seat 2. When the fan and the heating unit 10 inside the fan frame 7 are started simultaneously, air can be drawn in from the protective net bag 8, heated, and then sent into the interior of the first mounting ring seat 1 and the second mounting ring seat 2 for heating. The heating unit 10 is designed to be movable inside the movable cover 9. The protective net bag 8 at one end of the fan frame 7 can also be quickly disassembled and reassembled for internal cleaning and maintenance.

[0025] Working Principle: During use, the operator first installs the shaped pipe fitting liner mold inside the first mounting ring seat 1. Then, the second mounting ring seat 2 is rotated and adjusted along the movable shaft 12 on the surface of the back-through frame 6, so that the second mounting ring seat 2 aligns with the first mounting ring seat 1. The connection is sealed by the sealing ring 13. At this time, the shaped pipe fitting is completely covered by the hemispherical covers 3 at the upper and lower ends of the first and second mounting ring seats 1 and the exhaust seat 4. Heated airflow is then introduced from the back-through frame 6. Subsequently, the hot airflow enters the exhaust seat 4 along with the air guide 16. After being filtered by the ventilation bottom cover 14 and ventilation mesh 15 on the inner bottom wall of the first mounting ring seat 1, it flows upwards evenly, heating the shaped pipe fitting inside the first and second mounting ring seats 1 and 2. Finally, the heated airflow exits through the hemispherical covers 3 on the surface of the second mounting ring seat 2. The exhaust is quickly discharged from the cover 3 and the exhaust seat 4, thereby achieving a more uniform heating operation on the irregularly shaped pipe fittings and improving the processing effect of the PTFE material lining. In daily use, the operator can connect the entire fan frame 7 to one end of the back frame 6 through the ventilation grille 11 on the front. At the same time, the fan and heating unit 10 inside the fan frame 7 are started, and air is drawn in from the protective net bag 8, heated and then sent into the interior of the first mounting ring seat 1 and the second mounting ring seat 2 for heating operation. The heating unit 10 is designed to be movable inside the movable cover 9. The protective net bag 8 at one end of the fan frame 7 can also be quickly disassembled and reassembled for internal cleaning and maintenance operations. At the same time, the design of the first mounting ring seat 1 and the second mounting ring seat 2 also facilitates the quick cleaning operation of the interior while loading and unloading materials. The above is the complete working principle of this utility model.

[0026] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
