Abstract
Description
Technical Field
[0001] This utility model belongs to the field of feeding machine technology, specifically relating to a vibrating feeder. Background Technology
[0002] A vibrating feeder, also known as a vibrating feeder, is a device that can uniformly, regularly, and continuously feed block or granular materials from a storage bin to a receiving device.
[0003] When vibrating feeders convey materials with high humidity or high viscosity, the materials are prone to caking, and existing vibrating feeders cannot break up the caking materials, resulting in uneven feeding.
[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content
[0005] The purpose of this invention is to provide a vibrating feeder that can solve the problem of uneven feeding caused by the feeder's inability to break up clumps of material.
[0006] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:
[0007] A vibrating feeder, comprising:
[0008] The feeder body includes a feeding trough, with a feeding bin installed above the feeding port side of the feeding trough. The bottom wall of the feeding trough is inclined downwards from the feeding port side to the discharging port side. After the material is fed in through the feeding bin, the material falls onto the feeding trough and is then conveyed through the feeding trough under the action of vibration. The inclined setting of the feeding trough improves the conveying effect of the material.
[0009] The material handling mechanism includes a first screen plate installed inside a feed hopper. The first screen plate has multiple annular screen holes, allowing material entering the feed hopper to undergo preliminary screening through these holes. A magnetic suction component is installed at the bottom of the first screen plate, filtering out metal impurities after material passes through it. A second screen plate is installed below the first screen plate inside the feed hopper, allowing the material after screening through the first screen plate to undergo secondary screening, thus achieving a stepped screening process. The second screen plate has multiple annular screen holes, allowing material to be screened through these holes. Multiple grinding balls are also installed on the second screen plate to break up agglomerated material, grinding and crushing it before it passes through the screen holes for final screening. The feed hopper is rotatably connected to a rotating shaft, and a crushing and dispersing component is installed on the side wall of the rotating shaft. The crushing and dispersing component is used to crush and disperse the material on the first screen plate and the second screen plate. By rotating the rotating shaft, the crushing and dispersing component crushes and disperses the material on the first screen plate and the second screen plate, thereby improving the screening efficiency of the first screen plate and the second screen plate while crushing and dispersing the agglomerated material.
[0010] Preferably, when the vibrating conveyor conveys materials, the conveying trough and the feed bin vibrate, which causes the first screen plate and the second screen plate installed in the feed bin to vibrate, so as to drive the material on the first screen plate and the second screen plate to vibrate, thereby improving the screening efficiency of the first screen plate and the second screen plate and avoiding the blockage of agglomerated material in the first screen hole and the second screen hole.
[0011] In one or more embodiments of this utility model, a support frame is provided at the bottom of the feeding trough, and multiple vibration mechanisms are installed between the feeding trough and the support frame.
[0012] In one or more embodiments of the present invention, the magnetic suction assembly includes a plurality of first magnetic suction rings, all of which are fixedly connected to the bottom of the first sieve plate.
[0013] In one or more embodiments of this utility model, a plurality of first magnetic rings are respectively disposed directly below a plurality of first screen holes, and a second magnetic ring is fixedly connected to the bottom of the first magnetic ring, so that after the material is screened through the first screen holes, it will flow downward from both sides of the first magnetic ring, so that the first magnetic ring and the second magnetic ring can better filter the metal impurities in the material.
[0014] In one or more embodiments of this utility model, the ratio of the aperture of the first screen hole to the aperture of the second screen hole is 5:1, which allows the first screen plate to break down and screen large pieces of material, and the first screen hole to break down and screen small pieces of material, thereby achieving a stepped breaking down and screening of the material. The ratio of the diameter of the second screen hole to the diameter of the grinding ball is 1:2, ensuring that the grinding ball can easily detach from the second screen hole when it rolls and grinds and crushes the material on the second screen plate.
[0015] In one or more embodiments of this utility model, the crushing and dispersing component includes a pair of first stirring plates and a pair of second stirring plates. The pair of first stirring plates and the pair of second stirring plates are fixedly connected to the side wall of the rotating shaft, so that the rotation of the rotating shaft can drive the first stirring plates and the second stirring plates to rotate.
[0016] In one or more embodiments of this utility model, a pair of first stirring plates are disposed above the first screen plate, so that the pair of first stirring plates can break up and crush the material on the first screen plate while improving the screening efficiency of the first screen plate. A pair of second stirring plates are disposed above the second screen plate, so that the pair of second stirring plates can drive the grinding balls to roll and grind and crush the material on the second screen plate, and will also drive the material on the second screen plate to move, thereby improving the screening efficiency of the second screen plate.
[0017] In one or more embodiments of this utility model, a plurality of first crushing blades are fixedly connected to the front and rear side walls of the first stirring plate in a horizontal manner, and a plurality of second crushing blades are fixedly connected to the front and rear side walls of the first stirring plate in a vertical manner. The rotation of the first stirring plate can drive the first and second crushing blades to rotate, so that the first and second crushing blades can break up the agglomerated material.
[0018] Preferably, the vibration of the feed hopper will cause the components installed in the feed hopper to vibrate, thereby preventing material adhesion and improving the material processing effect.
[0019] In one or more embodiments of this utility model, the lower end of the rotating shaft passes through the first sieve plate and is mounted on the second sieve plate, and the rotating shaft is rotatably connected on the first sieve plate and the second sieve plate.
[0020] In one or more embodiments of this utility model, a motor is installed at the upper end of the rotating shaft, and a plurality of support rods are installed between the motor and the feed hopper. The rotating shaft is driven to rotate by the motor, and the support rods are used to support and fix the motor.
[0021] Compared with the prior art, this utility model uses a screen plate to screen materials and a material dispersing component to break up and crush the materials during screening, thus achieving a step-by-step dispersing and screening of materials. This allows the lumpy materials to be broken up and screened before being conveyed through the conveying trough, resulting in a uniform distribution of materials conveyed by the conveying trough and, consequently, a uniform feeding by the feeder.

Detailed Implementation
[0032] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0033] like Figures 1-4 As shown, a vibrating feeder according to one embodiment of the present invention includes a feeder body 1 and a material handling mechanism 2.
[0034] like Figures 1-4 As shown, the feeder body 1 includes a feeding trough 11. A feeding bin 12 is installed above the feeding port side of the feeding trough 11. The bottom wall of the feeding trough 11 is inclined downward from the feeding port side to the discharging port side. After the material is fed into the feeding bin 12, the material falls onto the feeding trough 11 through the feeding bin 12 and is conveyed by the feeding trough 11 under the action of vibration. The inclined setting of the feeding trough 11 improves the conveying effect of the material.
[0035] like Figures 1-4 As shown, a support frame 13 is provided at the bottom of the feeding trough 11, and multiple vibration mechanisms 14 are installed between the feeding trough 11 and the support frame 13.
[0036] like Figures 1-4As shown, the material handling mechanism 2 includes a first screen plate 21, which is installed inside the feed hopper 12. The first screen plate 21 has multiple first screen holes 22 arranged in a ring pattern, allowing material entering the feed hopper 12 to undergo preliminary screening through the first screen holes 22. A magnetic suction component is installed at the bottom of the first screen plate 21, filtering out metal impurities after the material passes through it. A second screen plate 25 is installed at the bottom of the first screen plate 21 inside the feed hopper 12, allowing the material screened by the first screen plate 21 to undergo secondary screening through the second screen plate 25, thus achieving a stepped screening of the material. The second screen plate 25 has multiple second screen holes 26 arranged in a ring pattern, allowing the material to be screened through the second screen holes 26. Multiple grinding balls 27 are provided on the second screen plate 25. To facilitate the dispersing of agglomerated materials, the grinding balls 27 grind and crush the materials on the second screen plate 25, so that the ground materials can be screened through the second screen holes 26. A rotating shaft 28 is rotatably connected inside the feed hopper 12. Crushing and dispersing components are installed on the side wall of the rotating shaft 28. The crushing and dispersing components are used to crush and disperse the materials on the first screen plate 21 and the second screen plate 25. By rotating the rotating shaft 28, the crushing and dispersing components crush and disperse the materials on the first screen plate 21 and the second screen plate 25, thereby improving the screening efficiency of the first screen plate 21 and the second screen plate 25 while crushing and dispersing agglomerated materials.
[0037] Preferably, when the vibrating conveyor conveys materials, the conveying trough 11 and the feeding bin 12 will vibrate, thereby causing the first screen plate 21 and the second screen plate 25 installed in the feeding bin 12 to vibrate, so as to drive the material vibration of the first screen plate 21 and the second screen plate 25, thereby improving the material screening efficiency of the first screen plate 21 and the second screen plate 25 while avoiding the blockage of agglomerated material in the first screen hole 22 and the second screen hole 26.
[0038] like Figures 4-6 As shown, the magnetic suction assembly includes multiple first magnetic suction rings 23, all of which are fixedly connected to the bottom of the first sieve plate 21.
[0039] like Figure 4 and Figure 5 As shown, multiple first magnetic rings 23 are respectively disposed directly below multiple first screen holes 22. A second magnetic ring 24 is fixedly connected to the bottom of the first magnetic ring 23, so that after the material is screened through the first screen holes 22, it will flow downward from both sides of the first magnetic ring 23, so that the first magnetic ring 23 and the second magnetic ring 24 can better filter the metal impurities in the material.
[0040] Preferably, the ratio of the aperture of the first screen hole 22 to the aperture of the second screen hole 26 is 5:1, which allows the first screen plate 21 to break down and screen large pieces of material, while the first screen hole 22 breaks down and screens small pieces of material, thereby achieving a stepped breaking down and screening of the material. The ratio of the diameter of the second screen hole 26 to the diameter of the grinding ball 27 is 1:2, ensuring that the grinding ball 27 can easily detach from the second screen hole 26 when it grinds and crushes the material by rolling on the second screen plate 25.
[0041] like Figure 3 and Figure 4 As shown, the crushing and dispersing component includes a pair of first stirring plates 29 and a pair of second stirring plates 212. The pair of first stirring plates 29 and the pair of second stirring plates 212 are fixedly connected to the side wall of the rotating shaft 28, so that the rotation of the rotating shaft 28 can drive the first stirring plates 29 and the second stirring plates 212 to rotate.
[0042] like Figure 3 and Figure 4 As shown, a pair of first stirring plates 29 are disposed above the first screen plate 21, so that the pair of first stirring plates 29 can break up and crush the material on the first screen plate 21 while improving the screening efficiency of the first screen plate 21. A pair of second stirring plates 212 are disposed above the second screen plate 25, so that the pair of second stirring plates 212 can drive the grinding balls 27 to roll and grind and crush the material on the second screen plate 25, and will also drive the material on the second screen plate 25 to move, thereby improving the screening efficiency of the second screen plate 25.
[0043] like Figure 6 As shown, multiple first crushing blades 210 are fixedly connected to the front and rear side walls of the first stirring plate 29 in a horizontal manner, and multiple second crushing blades 211 are fixedly connected to the front and rear side walls of the first stirring plate 29 in a vertical manner. The rotation of the first stirring plate 29 can drive the first crushing blades 210 and the second crushing blades 211 to rotate, so that the first crushing blades 210 and the second crushing blades 211 can break up the agglomerated material.
[0044] Preferably, the vibration of the feed hopper 12 will cause the components installed in the feed hopper 12 to vibrate, thereby preventing the material from adhering and improving the material processing effect.
[0045] like Figure 3 and Figure 4 As shown, the lower end of the rotating shaft 28 passes through the first sieve plate 21 and is installed on the second sieve plate 25, and the rotating shaft 28 is rotatably connected on the first sieve plate 21 and the second sieve plate 25.
[0046] like Figures 1-4As shown, a motor 213 is installed at the upper end of the rotating shaft 28. Multiple support rods 214 are installed between the motor 213 and the feed bin 12. The rotating shaft 28 is driven to rotate by the motor 213, and the support rods 214 are used to support and fix the motor 213.
[0047] It should be noted that the model of motor 213 is selected based on the material throughput of the feed hopper 12. At the same time, the vibration of the vibrating feeder is existing technology and will not be described in detail in the manual.
[0048] In use, the vibrating feeder is started, causing the conveying trough 11 and the feeding bin 12 to vibrate. The motor 213 is also started, which drives the first stirring plate 29 and the second stirring plate 212 to rotate, feeding the material into the feeding bin 12. The material falls onto the first screen plate 21, which is driven to rotate by the rotation of the first stirring plate 29. At the same time, the first stirring plate 29 drives the first crushing blade 210 and the second crushing blade 211 to rotate, breaking up the lumps of material. The material falls through the first screen hole 22 and then falls down. As the material falls, it can pass through the first magnetic ring 23 and the second magnetic ring 24 to filter out metal impurities. When the material falls onto the second screen plate 25, the rotation of the second stirring plate 212 drives the multiple grinding balls 27 to rotate, which can grind and crush the material to break up small pieces. The crushed material falls through the second screen hole 26 and then falls onto the conveying trough 11. The vibration of the conveying trough 11 then transports the screened material.
[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0050] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
