Description

Technical Field

[0001] The invention relates to the technical field of capacitor production and manufacturing, in particular to an aluminum foil removing device for a capacitor nailing and coiling machine. Background Art

[0002] A capacitor winding machine is a device used to manufacture capacitors. A capacitor is an electronic component used to store charge and release it in a circuit. During the manufacturing process of the capacitor, dielectric materials, electrodes and other components need to be wound together to increase the capacitance of the capacitor. During the winding process of the capacitor winding machine, the aluminum foil comes into contact with other components, such as the winding roller and tensioning device, and friction may occur. This friction may cause some tiny particles or debris on the surface of the aluminum foil to fall off, forming aluminum foil powder. The aluminum foil powder may enter the interior of the capacitor, causing the insulation capacity to weaken and increasing the risk of breakdown or leakage of the capacitor. Therefore, the capacitor winding machine needs to ensure that no aluminum foil powder remains during production.

[0003] Traditional aluminum foil dust removal equipment, such as the capacitor coiling machine aluminum foil removal device and capacitor coiling machine with publication number CN208460580U, uses a roller brush to clean the aluminum foil. However, since aluminum foil dust easily generates static electricity due to friction, the fine aluminum foil dust adheres to the capacitor winding through static electricity, making it difficult to remove. At the same time, traditional capacitor coiling machines also remove aluminum foil dust by suction, such as the dust removal device on an aluminum electrolytic capacitor coiling machine with publication number CN219738773U. However, this type of traditional cleaning device is also difficult to effectively remove aluminum foil dust adsorbed by static electricity, and the sucked-out aluminum foil dust can also cause blockage, requiring regular cleaning of the filter screen or filter bag, and requiring shutdown for maintenance, resulting in excessively high maintenance costs.

[0004] Therefore, in order to solve the above problems, a new technical solution is provided to meet the needs. Summary of the Invention

[0012] By adopting the above technical solution, aluminum foil powder can be intercepted more effectively.

[0013] Furthermore, a movable groove is provided in the rotating tube, and a metal movable column passes through the movable groove.

[0014] By adopting the above technical solution, the rotation of the rotating tube can be used to make the metal movable column move along the movable groove and hit the first filter adsorption belt and the second filter adsorption belt, thereby removing the aluminum foil.

[0015] Furthermore, a centrifugal turbine is provided in the centrifugal fan, and the rotating tube is fixedly connected to the centrifugal turbine via a transmission shaft.

[0016] By adopting the above technical solution, the rotating tube can drive the centrifugal turbine to rotate through the transmission shaft, thereby generating negative pressure.

[0017] Furthermore, a drive motor is provided on the capacitor nail roll frame, one end of the drive roller is connected to the drive motor through a synchronous belt, the drive roller is connected to the nearest rotating tube through a synchronous belt, and adjacent rotating tubes are connected through a synchronous belt.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0030] Combine Figure 1 - Figure 9A capacitor nail roll machine aluminum foil cleaning device includes a capacitor nail roll machine frame 1, a negative pressure cleaning box 2 is arranged under the capacitor nail roll frame 1, the negative pressure cleaning box 2 is used to suck in aluminum foil debris and dust for cleaning, and a suspended support frame 3 is fixedly connected above the capacitor nail roll frame 1, and a jet cleaning box 4 is arranged on the suspended support frame 3, and the jet cleaning box 4 is used to eject a high-speed airflow to blow away and remove tightly adsorbed debris.

[0031] like Figure 5 and Figure 6 As shown, a driving roller 5 is provided on one side of the negative pressure cleaning box 2, and a driving motor 15 is provided on the capacitor nail roll frame 1. One end of the driving roller 5 is connected to the driving motor 15 through a synchronous belt, so that the capacitor nail roll frame 1 is provided with a driving motor 15, and one end of the driving roller 5 is connected to the driving motor 15 through a synchronous belt to drive the driving roller 5 to rotate. A supporting roller 6 is provided on the other side of the negative pressure cleaning box 2, and a first filter adsorption belt 7 and a second filter adsorption belt 8 are provided outside the driving roller 5 and the supporting roller 6. A first supporting roller 9 is provided below the supporting roller 6, and a second supporting roller 10 is provided below the driving roller 5. A first friction rod 11 is provided between the first support roller 9 and the second support roller 10. The driving roller 5, the supporting roller 6, the first support roller 9, the second support roller 10 and the first friction rod 11 cooperate to tension the first filter adsorption belt 7, and the first friction rod 11 cannot rotate. In this way, when the driving roller 5 drives the first filter adsorption belt 7 to rotate, the first friction rod 11 can rub against the first filter adsorption belt 7. The first filter adsorption belt 7 is made of a nylon filter mesh, and the first friction rod 11 is made of metal. When nylon rubs against metal, the nylon may lose electrons, making it positively charged, while the metal will gain these electrons, thus becoming negatively charged. In this way, the positively charged first filter adsorption belt 7 can adsorb the negatively charged aluminum foil fragments and dust.

[0032] like Figure 5 and Figure 7 As shown, a third support roller 12 is provided below the support roller 6, a fourth support roller 13 is provided below the drive roller 5, and a second friction rod 14 is provided between the third support roller 12 and the fourth support roller 13. The drive roller 5, the support roller 6, the third support roller 12, the fourth support roller 13, and the second friction rod 14 cooperate to tension the second filter adsorption belt 8. The second filter adsorption belt 8 is made of a silk filter mesh, and the second friction rod 14 is made of glass and cannot rotate. The reason is that when glass rubs against silk, glass usually loses some electrons, leaving a positive charge, while silk gains these extra electrons, resulting in a negative charge. Therefore, after the second filter adsorption belt 8 rubs against the second friction rod 14, the second friction rod 14 will be negatively charged, thereby being able to absorb the positively charged aluminum foil debris and dust.

[0033] Furthermore, aluminum foil scraps and dust that don't carry static electricity aren't truly uncharged. Rather, they have an equal number of positive and negative charges, appearing neutral. Every atom consists of protons and electrons, with protons carrying a positive charge and electrons carrying a negative charge. While these charges are equal in number, strictly speaking, the positions of the positive and negative charges don't exactly coincide. Therefore, if a neutral atom is placed in an electric field, the protons will naturally be affected by the electric force and deflect in the direction of the field, while the electrons will be affected by the opposite force, shifting their center of motion in the opposite direction. Imagine a positively charged object approaching a small insulating object. The positive charge will attract the object's electrons while simultaneously repelling the object's nucleus. Since the electrons are closer to the charged object than the nucleus, the attractive force is slightly greater than the repulsive force, resulting in attraction. Because the object is an insulator, the electrons can only be attracted but cannot move freely, resulting in a macroscopic appearance of attraction. If both objects were conductors, contact would prevent attraction. For example, a charged metal rod cannot attract tinfoil because charges can move freely. When two conductors touch each other, they carry the same charge. However, if they are not touching, there will still be attraction. Therefore, the positively charged first filter adsorption belt 7 and the negatively charged second filter adsorption belt 8 can also generate adsorption force for those tiny debris that are not statically charged, which is more thorough and efficient than traditional wind removal.

[0034] An exhaust pipe 16 is provided in the negative pressure cleaning box 2, and a centrifugal fan 17 is provided at one end of the exhaust pipe 16. An air outlet 1702 is provided on the centrifugal fan 17, and the air outlet 1702 is connected to the jet cleaning box 4 through the air guide pipe 20. A rotating pipe 18 is provided at the other end of the exhaust pipe 16, and an exhaust port 1803 is provided on the rotating pipe 18. The driving roller 5 is connected to the nearest rotating pipe 18 through a synchronous belt, and the adjacent rotating pipes 18 are connected by a synchronous belt transmission. A centrifugal turbine 1701 is provided in the centrifugal fan 17, and the rotating pipe 18 is fixedly connected to the centrifugal turbine 1701 through a transmission shaft 19. The transmission shaft 19 is provided inside the exhaust pipe 16 and passes through the exhaust pipe 16. Therefore, while the driving motor 15 drives the driving roller 5 to rotate, it will also drive the rotating tube 18 to rotate through the synchronous belt transmission, and then drive the centrifugal turbine 1701 to rotate through the transmission shaft 19 to extract air, and extract the air through the exhaust port 1803. The rotating tube 18 is located on the inner side of the first filter adsorption belt 7 and the second filter adsorption belt 8. Therefore, the negative pressure generated by the exhaust will cause the air to flow through the first filter adsorption belt 7 and the second filter adsorption belt 8 into the negative pressure cleaning box 2. At the same time, the first filter adsorption belt 7 and the second filter adsorption belt 8 are distributed in the negative pressure cleaning box 2 in sequence, and there is no gap between the first filter adsorption belt 7 and the second filter adsorption belt 8. In this way, the first filter adsorption belt 7 and the second filter adsorption belt 8 can intercept the aluminum foil.

[0035] After the centrifugal fan 17 draws out the air, it will pump the air into the jet cleaning box 4 through the air exhaust port 1803 and the air duct 20. In addition, the jet cleaning box 4 is densely provided with jet ports 401 at the bottom, and the jet ports 401 face different directions, so that the aluminum foil and dust at different positions can be blown away.

[0036] In addition, the first friction rod 11 and the second friction rod 14 are in frictional contact with the outside of the first filter adsorption belt 7 and the second filter adsorption belt 8, respectively. Thus, when the first friction rod 11 and the second friction rod 14 are in friction with the outside of the first filter adsorption belt 7 and the second filter adsorption belt 8, respectively, the aluminum foil debris adhering to the outside of the first filter adsorption belt 7 and the second filter adsorption belt 8 can be scraped off to prevent clogging. A movable groove 1801 is provided in the rotating tube 18, and a metal movable column 1802 runs through the movable groove 1801. In this way, when the rotating tube 18 rotates, the metal movable column 1802 will move up and down in the movable groove 1801, and then the first filter adsorption belt 7 and the second filter adsorption belt 8 are cleaned by gravity impact, which can also prevent clogging.

The objectives of the present invention have been fully and effectively achieved.
