[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0022] Example 1
[0023] This utility model provides a pneumatic eight-sided slider tube expander for oxygen generator filter tubes, such as... Figures 1 to 4As shown, the system includes: a body 1 and a tube expansion assembly. The body 1 is used to expand the filter tube of the oxygen concentrator. The tube expansion assembly includes a booster cylinder 2, a connector 3, a limiting ring 4, a limiting component 5, a guide component 6, a movable component 7, and an elastic component 8. The booster cylinder 2 is located on the body 1. The connector 3 can be a rectangular block and is connected to the body 1. The limiting ring 4 is annular and is connected to the connector 3. The limiting component 5 is connected to the limiting ring 4 and can be a bolt with a limiting effect. The limiting component 5 is threaded into the limiting ring 4. The guide component 6 can be a guide rod with a guiding effect. The top diameter of the guide member 6 is smaller than the bottom diameter. A pneumatic lever cylinder is installed inside the guide member 6. The pneumatic lever cylinder is connected to the booster cylinder 2 through an air pipe. The guide member 6 is set on the connector 3. The movable member 7 can be a slider. The movable member 7 is movably set on the guide member 6. The elastic member 8 can be a return spring. The elastic member 8 is set on the limit ring 4. The booster cylinder 2 drives the movable member 7 to move laterally. Multiple movable members 7 are evenly spaced around the guide member 6. There are eight movable members 7. The elastic member 8 is set one-to-one with the movable member 7. The elastic member 8 is located inside the limit ring 4. The elastic member 8 keeps in contact with the movable member 7.
[0024] It can expand the filter tube of the oxygen generator through pneumatic principle, ensuring more stable product size. This not only effectively reduces equipment energy consumption, but also significantly reduces processing costs and significantly improves production efficiency.
[0025] In use, the booster cylinder 2 is activated. Since the guide component 6 is equipped with a pneumatic lever cylinder, which is connected to the booster cylinder 2 via an air pipe, the activation of the booster cylinder 2 will push the lever to pull the eight-sided movable component 7 to expand the mold core, thereby expanding the oxygen generator filter tube. At the same time, the movable component 7 will squeeze the elastic component 8, causing the elastic component 8 to deform. When the movable component 7 contacts the limit component 5, the expansion operation of the oxygen generator filter tube is completed. Then, the booster cylinder 2 is closed, and the oxygen generator filter tube is removed. At this time, due to its elasticity, the elastic component 8 will squeeze the movable component 7, causing the movable component 7 to move in the direction of the guide component 6. The reset operation of the movable component 7 is achieved by cooperating with the pneumatic lever cylinder.
[0026] Specifically, the bottom end of the booster cylinder 2 is fixedly installed on the top end of the machine body 1, the bottom end of the connecting piece 3 is fixedly installed on the top end of the machine body 1, the bottom end of the limit ring 4 is fixedly connected to the top end of the connecting piece 3, and the limit ring 4 is internally connected to the limit piece 5 via threads. The bottom end of the guide piece 6 is fixedly connected to the top end of the connecting piece 3, one end of the movable piece 7 is movably connected to the inside of the guide piece 6, and multiple elastic pieces 8 are fixedly connected inside the limit ring 4.
[0027] To ensure the smooth expansion of the oxygen generator filter tube, such as Figures 1 to 4As shown, a sliding assembly is provided on the limiting ring 4. The sliding assembly includes a guide rail 9, a slider 10, a roller 11, and a rubber component 12. The guide rail 9 is connected to the limiting ring 4. The slider 10 can be a sliding block and is movably disposed on the guide rail 9. The roller 11 is rotatably disposed on the slider 10. The rubber component 12 can be a rubber sheet and is bonded to the slider 10. The slider 10 moves along the guide rail 9 via the roller 11. Multiple guide rails 9 are evenly spaced on the limiting ring 4. The guide rail 9 is attached to the limiting component 5. The roller 11 is located above the limiting ring 4 and is attached to the limiting ring 4.
[0028] The sliding component effectively reduces the friction between the oxygen generator filter tube and the limiting ring 4, thereby reducing the pressure and wear on the oxygen generator filter tube during the tube expansion process, ensuring the smooth expansion of the oxygen generator filter tube, and thus improving the reliability of the equipment.
[0029] In use, first take out the oxygen concentrator filter tube that needs to be expanded, then align the oxygen concentrator filter tube with the guide 6, then move the oxygen concentrator filter tube downwards. The oxygen concentrator filter tube will contact and move along the outer surface of the guide 6. As the oxygen concentrator filter tube moves, it will also move along the outer surface of the movable part 7. Finally, the bottom end of the oxygen concentrator filter tube will contact the rubber part 12 on the sliding part 10. When the equipment expands the oxygen concentrator filter tube, the diameter of the oxygen concentrator filter tube will gradually increase. The bottom end of the oxygen concentrator filter tube will drive the sliding part 10 to move laterally. The sliding part 10 will drive the roller 11 to move along the outer surface of the limit ring 4.
[0030] Specifically, multiple guide rails 9 are fixedly connected to the top of the limiting ring 4 at the position inside the limiting member 5. A sliding member 10 is movably connected inside the guide rail 9. A roller 11 is rotatably connected to the bottom of the sliding member 10. The outer surface of the roller 11 is attached to the top surface of the limiting ring 4. A rubber member 12 is glued to the top of the sliding member 10.
[0031] Working Principle: In actual use, the oxygen concentrator filter tube to be expanded is first removed. Then, the filter tube is aligned with guide 6. Next, the filter tube is moved downwards, contacting and moving along the outer surface of guide 6. As the filter tube moves, it also moves along the outer surface of movable part 7. Finally, the bottom end of the filter tube contacts the rubber part 12 on sliding part 10. When the device expands the filter tube, its diameter gradually increases. The bottom end of the filter tube drives sliding part 10 to move laterally. Sliding part 10 drives roller 11 to move along the outer surface of limit ring 4. This effectively reduces the friction between the filter tube and limit ring 4, reducing pressure and wear on the filter tube during expansion, ensuring smooth expansion of the filter tube, and thus improving the reliability of the device.
[0032] Then, the booster cylinder 2 is activated. Since the guide component 6 has a pneumatic lever cylinder inside, which is connected to the booster cylinder 2 via an air pipe, the activation of the booster cylinder 2 will push the lever to pull the eight-sided movable component 7 to expand the mold core, thereby expanding the oxygen generator filter tube. At the same time, the movable component 7 will squeeze the elastic component 8, causing the elastic component 8 to deform. When the movable component 7 contacts the limit component 5, the expansion operation of the oxygen generator filter tube is completed. Then, the booster cylinder 2 is closed, and the oxygen generator filter tube is removed. At this time, due to its elasticity, the elastic component 8 will squeeze the movable component 7, causing the movable component 7 to move in the direction of the guide component 6. By cooperating with the pneumatic lever cylinder, the reset operation of the movable component 7 is achieved. The expansion operation of the oxygen generator filter tube can be realized through pneumatic principle, ensuring more stable product dimensions. This not only effectively reduces equipment energy consumption but also significantly reduces processing costs and significantly improves production efficiency.
[0033] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
