Description

Technical Field

[0001] This invention relates to the field of magnetic core screening equipment technology, specifically a magnetic core screening and feeding device. Background Technology

[0002] A magnetic core is a sintered magnetic metal oxide composed of various iron oxide mixtures. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical magnetic core materials. At the same time, the processing of magnetic cores requires the participation of screening devices, drying devices, curing devices, etc.

[0003] A Chinese patent (publication number CN212397314U) discloses a magnetic core appearance screening device. By setting a base, a slide, and a mounting plate around the turntable to support the various nozzles, the position of each nozzle can be adjusted simultaneously according to magnetic cores of different thicknesses, diameters, and shapes by adjusting the slide to move radially along the turntable and the mounting plate to move up and down. This makes it suitable for screening magnetic cores of various models and specifications and is very convenient to use.

[0004] However, when the magnetic core appearance screening device designed above is used, different magnetic cores are screened by setting up various nozzles. After screening, the magnetic cores rely on their own gravity to slide down into the receiving box during feeding. When the shape of the magnetic core is irregular, it is easy to get stuck and accumulate in the inclined track between the receiving box and the turntable, which affects the feeding rate of the magnetic core.

[0005] To address this problem, we designed a magnetic core screening and feeding device. Summary of the Invention

[0006] The purpose of this invention is to provide a magnetic core screening and feeding device to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides a magnetic core screening and feeding device, including a feeding pipe, a groove on one side of the feeding pipe, a sliding rod slidably inserted inside the groove, a lever fixedly connected to the bottom of the sliding rod, a sliding member fixedly connected to one end of the sliding rod, a rack fixedly installed on one side of the inner wall of the sliding member, a half gear meshing with one side of the rack, the half gear being rotatably installed on one side of the feeding pipe, and a drive assembly provided on one side of the half gear.

[0008] Furthermore, an mounting plate is fixedly installed on one side of the feeding tube, and a rotating rod is rotatably installed on one side of the mounting plate. A cam is sleeved in the middle of the rotating rod, and the cam movably abuts against one side of the outer wall of the feeding tube. There are two mounting plates, one of which has a rotating motor fixedly installed on its outer side, and the drive end of the rotating motor is fixedly connected to the rotating rod.

[0009] Furthermore, the drive assembly includes a pulley fixedly mounted on one side of the half gear, and there are two pulleys, one of which is located on one side of the mounting plate, and a belt is tensioned on the outer sides of both pulleys.

[0010] Furthermore, a mounting block is fixedly mounted on one side of the mounting plate, and a pulley is rotatably mounted on one side of the mounting block. The pulley is fixedly connected to a rotating rod via a rotating shaft.

[0011] Furthermore, a filter plate is fixedly installed on one side of the bottom of the feeding pipe, and an installation box is fixedly installed at the bottom of the feeding pipe, with a dust collection box slidably inserted into the interior of the installation box.

[0012] Furthermore, a guide slider is fixedly connected to one side of the slide rod, and a guide groove is provided on one side of the slide groove, with the guide slider slidably connected to the guide groove.

[0013] Furthermore, a handle is fixedly installed on one side of the dust collection box, and the handle is provided with an integrally formed anti-slip texture.

[0014] Furthermore, the lever is slidably connected to the bottom of the inner wall of the feed tube, and the lever is made of rubber.

[0015] Furthermore, a flexible metal strip is provided on the bottom surface of the feeding tube. In the conveying direction of the feeding tube, both ends of the flexible metal strip are fixedly connected to the bottom surface of the feeding tube. The length of the flexible metal strip is greater than the distance between its two fixed points. The flexible metal strip is provided corresponding to the cam.

[0016] Furthermore, the rotating rod has multiple cams, and the mounting angles of the multiple cams on the rotating rod are consistent. A pressure plate is provided in the middle of the flexible metal strip, and the two ends of the pressure plate are fixedly connected to the bottom surface of the feeding tube. The cams are correspondingly provided with the flexible metal strip on one side of the pressure plate, and the flexible metal strip can slide between the pressure plate and the feeding tube.

[0017] A first magnet is embedded in the tip of the cam, and a second magnet is fixedly disposed below the flexible metal strip corresponding to the position of the cam. When the tip of the cam contacts the bottom surface of the feed tube, the first magnet and the second magnet repel each other. A spring is disposed between the flexible metal strip and the bottom surface of the feed tube, and the spring is located at the second magnet. When the tip of the cam moves away from the bottom surface of the feed tube, the spring contracts.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: when the good product discharge nozzle sprays air onto the magnetic core to make the magnetic core detach from the turntable, the magnetic core slides down the inner wall of the inclined feed tube. When it slides to the end, the half gear can be driven to rotate through the belt pulley. The rack is meshed by the half gear, and the sliding part moves synchronously with the rack, which drives the sliding rod to move synchronously. The lever at the bottom of the sliding rod can move the magnetic core during the movement, so that the magnetic core can fall from the feed tube into the receiving bucket for receiving the magnetic core.

[0019] Compared with the prior art, the beneficial effects of the present invention are: starting the rotating motor can drive the rotating rod to rotate, and the rotating rod drives the cam to rotate at the same time. When the cam rotates, it intermittently contacts the feeding tube, causing the feeding tube to vibrate, which facilitates increasing the feeding speed of the magnetic core in the feeding tube.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-4The present invention provides a technical solution comprising a feeding pipe 1, a groove 5 on one side of the feeding pipe 1, a sliding rod 3 slidably inserted inside the groove 5, a lever 4 fixedly connected to the bottom of the sliding rod 3, a sliding member 6 fixedly connected to one end of the sliding rod 3, a rack 7 fixedly installed on one side of the inner wall of the sliding member 6, a half gear 8 meshing with one side of the rack 7, the half gear 8 rotatably mounted on one side of the feeding pipe 1, a drive assembly provided on one side of the half gear 8, the drive assembly including a pulley 9 fixedly mounted on one side of the half gear 8, two pulleys 9 being provided, one of the pulleys 9 being located on one side of the mounting plate 2, a belt 10 being tensioned together on the outer sides of the two pulleys 9, a mounting block 12 fixedly mounted on one side of the mounting plate 2, the pulley 9 rotatably mounted on one side of the mounting block 12, the pulley 9 being fixedly connected to a rotating rod 13 via a rotating shaft, and the lever 4 being slidably connected to the bottom of the inner wall of the feeding pipe 1, the lever 4 being made of rubber.

[0028] It should be noted that the top end of the feed pipe 1 should be located on one side of the magnetic core screening device, below the device for placing magnetic cores such as the turntable. The magnetic cores are screened by nozzles on the turntable. This is existing technology and will not be described in detail here.

[0029] In practice, the magnetic core is located on an external turntable, with the feeding pipe 1 positioned on one side of the turntable of the magnetic core screening device. When the good product discharge nozzle sprays air onto the magnetic core, causing it to detach from the turntable, the magnetic core falls onto the feeding pipe 1 and slides down the inclined inner wall of the feeding pipe 1. When the magnetic core slides down to a section at the end of the feeding pipe 1, to prevent the magnetic core from accumulating, the rotating motor 15 can be started. The rotating motor 15 drives the rotating rod 13 to rotate, and simultaneously drives the pulley 9 to rotate. The two pulleys 9 are driven by the belt 10, and one of the pulleys 9 drives the half gear. When the gear 8 rotates, the half gear 8 and the pulley 9 rotate synchronously. The rack 7 is meshed by the half gear 8. There are two racks 7, which are symmetrically arranged on both sides of the inner wall of the sliding member 6 with the half gear 8 as the center. During the intermittent meshing process between the rack 7 and the half gear 8, the sliding member 6 is driven to move synchronously with the rack 7. The sliding member 6 drives the sliding rod 3 to move synchronously. The sliding rod 3 slides in the sliding groove 5. The lever 4 at the bottom of the sliding rod 3 can move the magnetic core during the movement, so that the magnetic core can fall from the feed tube 1 into the storage bucket that receives the magnetic core.

[0030] See Figure 1 and Figure 3 A mounting plate 2 is fixedly installed on one side of the feeding pipe 1. A rotating rod 13 is rotatably installed on one side of the mounting plate 2. A cam 14 is sleeved in the middle of the rotating rod 13. The cam 14 movably abuts against one side of the outer wall of the feeding pipe 1. There are two mounting plates 2. A rotating motor 15 is fixedly installed on the outer side of one of the mounting plates 2. The drive end of the rotating motor 15 is fixedly connected to the rotating rod 13.

[0031] By setting cam 14, starting the rotating motor 15 can drive the rotating rod 13 to rotate. While the rotating rod 13 rotates, it drives cam 14 to rotate. When cam 14 rotates, it intermittently contacts the feeding tube 1, causing the feeding tube 1 to vibrate, which facilitates increasing the feeding speed of the magnetic core in the feeding tube 1.

[0032] See Figure 3 and Figure 4 A filter plate 16 is fixedly installed on one side of the bottom of the feed pipe 1. An installation box 17 is fixedly installed on the bottom of the feed pipe 1. A dust collection box 18 is slidably inserted into the inside of the installation box 17. A handle is fixedly installed on one side of the dust collection box 18. The handle is provided with an integrally formed anti-slip texture.

[0033] By setting up a filter plate 16, when the magnetic core slides down the inclined section of the feeding pipe 1 to the bottom, the powder adhering to the magnetic core will slide from the top to the bottom of the feeding pipe 1. The filter plate 16 has small filter holes, and the powder can slide through the filter holes and fall into the dust collection box 18. The staff can remove the dust collection box 18 to empty the powder, and the magnetic core can slide from the bottom end of the feeding pipe 1 to the external storage bucket.

[0034] See Figure 2 A guide slider is fixedly connected to one side of the slide rod 3, and a guide groove 11 is provided on one side of the slide groove 5. The guide slider is slidably connected to the guide groove 11.

[0035] By providing guide sliders at both the upper and lower ends of the slide rod 3 inside the slide groove 5, and making the guide sliders slidably connected to the guide groove 11, the stability of the slide rod 3 can be improved.

[0036] Working principle: When the device is in use, the magnetic core is located on the external turntable, with the feeding pipe 1 positioned on one side of the turntable of the magnetic core screening device. When the good product discharge nozzle sprays air onto the magnetic core, causing it to detach from the turntable, the magnetic core falls onto the feeding pipe 1 and slides down the inclined inner wall of the feeding pipe 1. When the magnetic core slides down to a section at the end of the feeding pipe 1, to prevent the magnetic core from accumulating, the half gear 8 can be driven to rotate. The half gear 8 and the pulley 9 rotate synchronously, and the rack 7 is meshed with the half gear 8. During the intermittent meshing process between the rack 7 and the half gear 8... The sliding member 6 moves synchronously with the rack 7, and the sliding member 6 drives the sliding rod 3 to move synchronously. The sliding rod 3 slides in the sliding groove 5. The lever 4 at the bottom of the sliding rod 3 can move the magnetic core during the movement, so that the magnetic core can fall from the feeding tube 1 into the receiving bucket for receiving the magnetic core. Starting the rotating motor 15 can drive the rotating rod 13 to rotate. When the rotating rod 13 rotates, it drives the cam 14 to rotate. When the cam 14 rotates, it intermittently contacts the feeding tube 1, causing the feeding tube 1 to vibrate, which helps to increase the feeding speed of the magnetic core in the feeding tube 1.

[0037] Preferred, such as Figure 5As shown, a flexible metal strip 19 is provided on the bottom surface of the feeding tube 1. The flexible metal strip 19 is made of beryllium bronze with a thickness of 0.8 mm and a length redundancy of 5-10%. In the conveying direction of the feeding tube 1, both ends of the flexible metal strip 19 are fixedly connected to the bottom surface of the feeding tube 1. The length of the flexible metal strip 19 is greater than the distance between its two fixed points. The flexible metal strip 19 is set in accordance with the cam 14, so that it forms a certain relaxed state to facilitate subsequent elastic deformation.

[0038] Furthermore, multiple cams 14 are provided on the rotating rod 13. The cams 14 are made of 45 steel. The installation angles of the multiple cams 14 on the rotating rod 13 are consistent. A pressure plate 20 is provided in the middle of the flexible metal strip 19. The two ends of the pressure plate 20 are fixedly connected to the bottom surface of the feed tube 1. The cams 14 are correspondingly provided with the flexible metal strip 19 on one side of the pressure plate 20. The flexible metal strip 19 can slide between the pressure plate 20 and the feed tube 1. The pressure plate 20 is made of 304 stainless steel. The distance between the pressure plate 20 and the bottom surface of the feed tube 1 is 2mm.

[0039] A first magnet 21 is embedded in the tip of the cam 14. A second magnet 22 is fixedly disposed below the flexible metal strip 19 corresponding to the position of the cam 14. Multiple second magnets 22 can be arranged in an array to adapt to the deformation of the flexible metal strip 19. The first magnet 21 and the second magnet 22 are neodymium iron boron magnets. When the tip of the cam 14 contacts the bottom surface of the feed tube 1, the first magnet 21 and the second magnet 22 repel each other. A spring 23 is disposed between the flexible metal strip 14 and the bottom surface of the feed tube 1. The spring 23 is located at the second magnet 22. When the tip of the cam 14 moves away from the bottom surface of the feed tube 1, the spring 23 contracts.

[0040] During operation, when the rotating rod 13 drives the cam 14 to rotate until it contacts the bottom surface of the feeding pipe 1, the tip of the cam 14 collides with the bottom surface of the feeding pipe 1 and vibrates. At the same time, the repulsive force between the first magnet 21 and the second magnet 22 causes the flexible metal strip 19 to undergo elastic deformation. The flexible metal strip 19 corresponding to the second magnet 22 protrudes upward, and another part of the flexible metal strip 19 is straightened. When the cam 14 rotates until the tip is far away from the bottom surface of the feeding pipe 1, the repulsive force between the magnets disappears, the spring 23 begins to contract, and the flexible metal strip 19 at the second magnet 22 returns to its original position. The other part of the flexible metal strip 19 protrudes upward. The rotating rod 13 drives the cam 14 to rotate continuously, realizing a reciprocating vibration effect, thereby applying a certain vibration and disturbance to the material in the feeding pipe 1, improving the smoothness of the feeding pipe 1 in the material transmission process, and effectively preventing the occurrence of blockage.
