Description

Technical Field

[0001] The utility model relates to the technical field of sealing equipment, in particular to an end sealing device for a steel wire framework plastic composite pipe. Background Art

[0002] The steel wire framework plastic composite pipe uses high-strength over-plastic steel wire mesh and thermoplastic polyethylene as raw materials. The steel wire winding mesh serves as the framework reinforcement of the polyethylene plastic pipe. Since the steel wire framework plastic composite pipe has a steel wire framework as the reinforcement layer and polyethylene plastic is coated on the inner and outer walls, after being produced in a fixed length, the steel wire framework will be exposed at both ends. Therefore, it is necessary to seal the end faces.

A threaded rotating shaft is fixedly connected to the output shaft of the servo motor. An adjusting sleeve is threadedly connected to the outside of the threaded rotating shaft. A connecting block is fixedly connected to the outside of the adjusting sleeve. One end of the connecting block away from the adjusting sleeve is fixedly connected to a first mounting plate. By starting the driving motor, the grinding disc grinds the pipe orifice to be flat, and the heating disc heats the PE sealing ring and the pipe orifice of the steel wire mesh framework plastic composite pipe. When the heating is completed, the first electric push rod is started to make the PE sealing ring contact the pipe orifice of the steel wire mesh framework plastic composite pipe.

[0004] When the device is in use, the end of the steel wire framework plastic composite pipe is ground flat by the rotating grinding disc. However, when grinding and leveling by the rotating grinding disc, waste chips may fly, polluting the working site, which is inconvenient for subsequent workers to clean up the splashed processing waste chips and increases the workload of the workers.

Two threaded rods 18 are symmetrically and rotatably arranged on the upper surface of the workbench 1 in a limited manner. A lifting block 17 is sleeved and connected with a threaded sleeve on the outer sides of the two first chutes 8. A protective cover 16 is jointly connected between the two lifting blocks 17. The protective cover 16 is located directly above the grinding disc assembly 14. An activity port 19 is opened on one side wall of the protective cover 16. Finally, a transparent observation window 20 is arranged on the other side wall of the protective cover 16. Through the arrangement of the transparent observation window 20, the inside of the protective cover 16 can be observed;

[0021] When it is necessary to polish the end of the steel wire skeleton plastic composite pipe flat by the grinding disc assembly 14, first adjust and rotate the two threaded rods 18. Then, drive the lifting block 17 through the two threaded rods 18 in a threaded manner to drive the protective cover 16 arranged between the two lifting blocks 17 to move downward. At this time, the outside of the steel wire skeleton plastic composite pipe passes through the activity port 19, and the polishing end is left inside the protective cover 16. At the same time as the protective cover 16 moves downward, the grinding disc assembly 14 is covered. Then, the end of the steel wire skeleton plastic composite pipe is polished by the grinding disc assembly 14. At this time, the protective cover 16 covers the processing debris to prevent splashing. At the same time, the polishing situation of the grinding disc assembly 14 inside the protective cover 16 is observed through the transparent observation window 20. After polishing, adjust the protective cover 16 to move upward, so as to facilitate the subsequent processing of the end of the steel wire skeleton plastic composite pipe;

[0022] As a further implementation manner of this embodiment, such as Figures 1-4As shown in the figure, two mounting brackets 2 are provided on the upper surface of the workbench 1 and on one side of the protective cover 16. Then, a lower fixing block 3 is fixedly provided on the inner bottom wall of each of the two mounting brackets 2. Next, a hydraulic push rod 5 is provided on the inner top wall of each of the two mounting brackets 2, and an upper fixing block 4 is connected to the free end of each of the two hydraulic push rods 5. At the same time, a first electric push rod 6 is provided on the upper surface of the workbench 1 and on one side of the two mounting brackets 2, and a push plate 7 is connected to the free end of the first electric push rod 6. Then, a second electric push rod 21 is provided on the upper surface of the workbench 1 and on one side of the grinding wheel assembly 14 and the heating plate assembly 15. Next, a suction cup 22 is connected to the free end of the second electric push rod 21, and a PE sealing ring is provided on the suction cup 22. During use, the PE sealing ring is pushed by the second electric push rod 21 to seal the end of the steel wire skeleton plastic composite pipe;

[0023] During adjustment and use, first place the steel wire skeleton plastic composite pipe on the two lower fixing blocks 3. Then, drive the two upper fixing blocks 4 to move downward by the two hydraulic push rods 5, so as to limit and fix the steel wire skeleton plastic composite pipe through the lower fixing blocks 3 and the upper fixing blocks 4. Next, polish the end of the steel wire skeleton plastic composite pipe flat by the grinding wheel assembly 14. Subsequently, heat the end of the steel wire skeleton plastic composite pipe by the heating plate assembly 15. Then, push the PE sealing ring by the second electric push rod 21 to seal the end of the steel wire skeleton plastic composite pipe;

[0024] Specific working principle:

[0025] During adjustment and use, first place the steel wire skeleton plastic composite pipe on the two lower fixing blocks 3. Then, drive the two upper fixing blocks 4 to move downward through the two hydraulic push rods 5, so as to limit and fix the steel wire skeleton plastic composite pipe through the lower fixing blocks 3 and the upper fixing blocks 4. Next, threadedly drive the slider 11 and the connecting plate 12 through the lead screw 10 to drive the grinding disc assembly 14 on the fixing plate 13 to move to the end of the steel wire skeleton plastic composite pipe. Then, threadedly drive the lifting blocks 17 through the two threaded rods 18 to drive the protective cover 16 arranged between the two lifting blocks 17 to move downward. At this time, the outer side of the steel wire skeleton plastic composite pipe passes through the movable opening 19, while the grinding end is left inside the protective cover 16, and the protective cover 16 covers the grinding disc assembly 14 while moving downward. Then, grind the end of the steel wire skeleton plastic composite pipe through the grinding disc assembly 14. After grinding, adjust the protective cover 16 upward. Similar to the movement and adjustment of the grinding disc assembly 14, adjust and move the heating disc assembly 15 to the end of the steel wire skeleton plastic composite pipe. At this time, release the limitation of the lower fixing blocks 3 and the upper fixing blocks 4 on the steel wire skeleton plastic composite pipe. Drive the push plate 7 through the first electric push rod 6 to push the steel wire skeleton plastic composite pipe, so that the end of the steel wire skeleton plastic composite pipe approaches and contacts the heating disc assembly 15. Heat the end of the steel wire skeleton plastic composite pipe through the heating disc assembly 15. Subsequently, limit and fix the steel wire skeleton plastic composite pipe again. Then, drive the PE sealing ring through the second electric push rod 21 to seal the end of the steel wire skeleton plastic composite pipe.
