Description

Technical Field

[0001] This invention relates to the field of capacitor manufacturing technology, specifically to an aluminum foil removal device for a capacitor nailing machine. Background Technology

[0002] A capacitor nailing and winding machine is a device used to manufacture capacitors. A capacitor is an electronic component used to store and release electrical charge in a circuit. During the manufacturing process, 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 nailing and winding machine, aluminum foil comes into contact with other components, such as winding rollers and tensioning devices, which may cause friction. This friction may cause some tiny particles or shavings on the surface of the aluminum foil to fall off, forming aluminum foil dust. Aluminum foil dust may enter the inside of the capacitor, weakening its insulation and increasing the risk of capacitor breakdown or leakage. Therefore, the capacitor nailing and winding machine must ensure that there is no aluminum foil dust residue during production.

[0003] Traditional aluminum foil dust removal equipment, such as the aluminum foil removal device and capacitor nailing machine with publication number CN208460580U, uses roller brushes to clean the aluminum foil. However, because aluminum foil dust easily generates static electricity due to friction, the fine aluminum foil dust adheres to the capacitor winding through static electricity, making removal difficult. At the same time, traditional capacitor nailing machines also use air suction to remove aluminum foil dust, such as the dust removal device on an aluminum electrolytic capacitor nailing machine with publication number CN219738773U. However, these traditional cleaning devices are also difficult to effectively remove the electrostatically adsorbed aluminum foil dust, and the sucked-out aluminum foil dust can also cause blockages, requiring regular cleaning of the filter screen or filter bag. Maintenance requires machine shutdown, resulting in excessive maintenance costs.

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

[0005] To address the aforementioned problems, this invention discloses an aluminum foil removal device for a capacitor nail rolling machine, which improves aluminum foil removal efficiency and reduces capacitor quality issues.

[0006] The technical solution of the present invention is: an aluminum foil removal device for a capacitor nail rolling machine, including a capacitor nail rolling machine frame, a negative pressure cleaning box arranged below the capacitor nail rolling machine frame, a suspended support frame fixedly connected above the capacitor nail rolling machine frame, and an air jet cleaning box arranged on the suspended support frame; A drive roller is provided on one side of the negative pressure cleaning box, and a support roller is provided on the other side of the negative pressure cleaning box. A first filter adsorption belt and a second filter adsorption belt are provided outside the drive roller and the support roller. A first support roller is provided below the support roller, and a second support roller is provided below the drive roller. A first friction rod is provided between the first support roller and the second support roller. The drive roller, the support roller, the first support roller, the second support roller and the first friction rod cooperate to tension the first filter adsorption belt. A third support roller is provided below the support roller, and a fourth support roller is provided below the drive roller. A second friction rod is provided between the third and fourth support rollers. The drive roller, support roller, third support roller, fourth support roller and second friction rod cooperate to tension the second filter adsorption belt. The negative pressure cleaning box is equipped with an air extraction pipe. One end of the air extraction pipe is equipped with a centrifugal fan with an air outlet. The air outlet is connected to the air jet cleaning box through an air guide pipe. The other end of the air extraction pipe is equipped with a rotating pipe with an air extraction port.

[0007] Furthermore, the first filter adsorption belt is made of nylon material, the first friction rod is made of metal, and the first friction rod cannot rotate.

[0008] By adopting the above technical solution, the first filter adsorption belt can rub against the first friction rod when it rotates, and generate positive charge.

[0009] Furthermore, the second filter adsorption belt is made of silk material, the second friction rod is made of glass, and the second friction rod cannot rotate.

[0010] By adopting the above technical solution, the second filter adsorption belt can rub against the second friction rod when it rotates, and generate a negative charge.

[0011] Furthermore, the first and second filter adsorption belts are sequentially and alternately distributed within the negative pressure cleaning box, with no gaps between them.

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

[0013] Furthermore, a movable groove is provided inside 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 impact the first filter adsorption belt and the second filter adsorption belt, thereby removing the aluminum foil.

[0015] Furthermore, the centrifugal fan is equipped with a centrifugal turbine, and the rotating pipe is fixedly connected to the centrifugal turbine via a drive 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 rolling machine frame, one end of the drive roller is connected to the drive motor via a synchronous belt, the drive roller is connected to the nearest rotating tube via a synchronous belt, and adjacent rotating tubes are connected to each other via synchronous belts.

[0018] By adopting the above technical solution, the drive motor can simultaneously drive the roller and the rotating tube to rotate.

[0019] Furthermore, the rotating tube is located inside the first and second filter adsorption belts.

[0020] By adopting the above technical solution, when the rotating tube draws in air and generates negative pressure, the airflow will pass through the first and second filter adsorption belts, which facilitates the filtration of aluminum foil.

[0021] Furthermore, the first friction rod and the second friction rod respectively rub against the outer sides of the first filter adsorption belt and the second filter adsorption belt.

[0022] By adopting the above technical solution, when the first friction rod and the second friction rod rub against the first filter adsorption belt and the second filter adsorption belt respectively, the aluminum foil adsorbed on the outside of the first filter adsorption belt and the second filter adsorption belt can be scraped off, thus avoiding blockage.

[0023] Furthermore, the jet cleaning box has densely packed jet nozzles at its bottom, and the jet nozzles face different directions.

[0024] By adopting the above technical solution, airflow jets can be used to remove aluminum foil powder and dust.

[0025] Advantages of this invention: 1. The present invention provides an aluminum foil removal device for a capacitor nail rolling machine. By setting up a first filter adsorption belt and a second filter adsorption belt that are arranged in an alternating manner, the first filter adsorption belt made of nylon material can generate a positive charge with the first friction rod made of metal material, thereby adsorbing those negatively charged tiny dust particles and aluminum foil debris. Meanwhile, the second filter adsorption belt made of silk material generates a negative charge by rubbing with the second friction rod made of glass material, thereby adsorbing those positively charged tiny dust particles and aluminum foil debris, thus enhancing the removal ability and the ability to remove statically charged debris.

[0026] 2. The present invention provides an aluminum foil removal device for a capacitor nail rolling machine. By setting up a centrifugal fan, the first and second filter adsorption belts can rotate while the centrifugal fan can also draw in air, thereby reducing the pressure inside the negative pressure cleaning box. In turn, the air pressure can be used to draw dust and aluminum foil debris into the negative pressure cleaning box, thus enhancing the adsorption and cleaning capacity. Attached Figure Description

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

[0030] Combination Figure 1 - Figure 9A capacitor nail roll machine aluminum foil removal device includes a capacitor nail roll machine frame 1, a negative pressure cleaning box 2 is provided below the capacitor nail roll machine frame 1, the negative pressure cleaning box 2 is used to suck up aluminum foil debris and dust for cleaning, a suspended support frame 3 is fixedly connected above the capacitor nail roll machine frame 1, and an air jet cleaning box 4 is provided on the suspended support frame 3, the air jet cleaning box 4 is used to spray high-speed airflow to blow away and remove tightly adsorbed debris.

[0031] like Figure 5 and Figure 6 As shown, a drive roller 5 is provided on one side of the negative pressure cleaning box 2, and a drive motor 15 is provided on the capacitor nail rolling machine frame 1. One end of the drive roller 5 is connected to the drive motor 15 via a synchronous belt, so that the drive roller 5 can be driven to rotate. A support roller 6 is provided on the other side of the negative pressure cleaning box 2. A first filter adsorption belt 7 and a second filter adsorption belt 8 are provided outside the drive roller 5 and the support roller 6. A first support roller 9 is provided below the support roller 6, and a second support roller 10 is provided below the drive roller 5. A first friction rod 11 is provided between the first support roller 9 and the second support roller 10. The drive roller 5, the support roller 6, the first support roller 9, the second support roller 10 and the first friction rod 11 work together to tension the first filter adsorption belt 7, and the first friction rod 11 cannot rotate. In this way, when the drive 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 nylon material, and the first friction rod 11 is made of metal. When nylon rubs against metal, nylon may lose electrons and become positively charged, while metal will gain these electrons and become negatively charged. In this way, the positively charged first filter adsorption belt 7 can adsorb those negatively charged aluminum foil fragments and dust.

[0032] like Figure 5 and Figure 7 As shown, a third support roller 12 is arranged below the support roller 6, and a fourth support roller 13 is arranged below the drive roller 5. A second friction rod 14 is arranged between the third support roller 12 and the fourth support roller 13. The drive roller 5, support roller 6, third support roller 12, fourth support roller 13, and second friction rod 14 work together to tension the second filter adsorption belt 8. The second filter adsorption belt 8 is made of silk mesh, and the second friction rod 14 is made of glass and cannot rotate. Similarly, 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 become negatively charged, thus adsorbing the positively charged aluminum foil debris and dust.

[0033] Furthermore, those seemingly static-free aluminum foil scraps and dust aren't truly without charge; rather, they have an equal number of positive and negative charges, appearing neutral. Every atom has protons and electrons; protons are positively charged, and electrons are negatively charged, with equal numbers of charges. However, strictly speaking, the positions of the positive and negative charges don't perfectly coincide. Therefore, if this neutral atom is placed in an electric field, the protons will naturally be affected by the electric field force, shifting in the direction of the field, while the electrons will be affected by the opposite electric field 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 electrons of the insulating object while repelling the atomic 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 it's an insulator, the electrons can only be attracted but cannot move freely, so macroscopically, it manifests as an attractive force. If both objects are conductors, they won't attract each other. For example, a charged metal rod cannot attract tin foil because charges can move freely. When two conductors touch, they become charged with the same type of charge, but if they don't touch, there will still be an attraction. Therefore, the first filter adsorption band 7, which carries a positive charge, and the second filter adsorption band 8, which carries a negative charge, can also attract tiny debris that is not charged with static electricity, making it more thorough and efficient than traditional wind removal.

[0034] The negative pressure cleaning box 2 is equipped with an exhaust pipe 16. A centrifugal fan 17 is installed at one end of the exhaust pipe 16, and an air outlet 1702 is installed on the centrifugal fan 17. The air outlet 1702 is connected to the jet cleaning box 4 through an air guide pipe 20. A rotating pipe 18 is installed at the other end of the exhaust pipe 16, and an exhaust port 1803 is opened on the rotating pipe 18. The drive roller 5 is connected to the nearest rotating pipe 18 through a synchronous belt. Adjacent rotating pipes 18 are connected to each other through synchronous belts. A centrifugal turbine 1701 is installed inside the centrifugal fan 17. The rotating pipe 18 is fixedly connected to the centrifugal turbine 1701 through a drive shaft 19. The drive shaft 19 is located inside the exhaust pipe 16 and passes through the exhaust pipe 16. The drive motor 15 drives the drive roller 5 to rotate, and at the same time, it drives the rotating tube 18 to rotate through the synchronous belt drive. Then, the centrifugal turbine 1701 is driven to rotate through the transmission shaft 19 to extract air. The air is extracted through the air extraction port 1803. The rotating tube 18 is located inside the first filter adsorption belt 7 and the second filter adsorption belt 8. Therefore, the negative pressure generated by the air extraction 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 alternately in the negative pressure cleaning box 2, and there are no gaps 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 pumps the air into the jet cleaning box 4 through the air extraction port 1803 and the air guide pipe 20. In addition, jet cleaning box 4 has densely arranged jet ports 401 at the bottom, and the jet ports 401 face different directions, so aluminum foil and dust in different positions can be blown away.

[0036] Furthermore, the first friction rod 11 and the second friction rod 14 respectively rub against the outer sides of the first filter adsorption belt 7 and the second filter adsorption belt 8. When the first friction rod 11 and the second friction rod 14 rub against the outer sides of the first filter adsorption belt 7 and the second filter adsorption belt 8, they can scrape off the aluminum foil debris adhering to the outer sides of the first filter adsorption belt 7 and the second filter adsorption belt 8, preventing blockage. Additionally, a movable groove 1801 is provided inside the rotating tube 18, and a metal movable column 1802 passes through the movable groove 1801. Thus, when the rotating tube 18 rotates, the metal movable column 1802 moves up and down within the movable groove 1801, thereby cleaning the first filter adsorption belt 7 and the second filter adsorption belt 8 through gravity impact, also preventing blockage.

The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from the stated principles.
