Description

Technical Field

[0001] This utility model relates to the field of vibratory feeder silos, and in particular to a multi-stage flexible vibratory feeder silo. Background Technology

[0002] In the field of industrial automation production, vibratory feeder hoppers, as core equipment for material conveying and sorting, are widely used in industries such as electronics, automobiles, and hardware. Their performance directly affects the efficiency and precision of subsequent processes.

[0003] However, the limitations of traditional vibratory feeder hoppers are becoming increasingly apparent when dealing with sheet-like materials (such as stamped metal sheets and plastic films), especially those with multi-faceted or hook-like structures. Traditional hoppers often employ a single cavity or a gentle conveying channel design, lacking a targeted dispersing structure. Under high-frequency vibration, materials tend to clump together and aggregate, often falling in clusters without achieving single-particle, orderly conveying. This disrupts subsequent sorting and gripping processes, severely limiting the continuous operating efficiency of automated production lines. Therefore, a multi-stage flexible vibratory feeder hopper is urgently needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-stage flexible vibratory feeder hopper. Its objective is to efficiently solve the problem of piling up thin, multi-faceted, and hook-shaped materials through a stepped hopper body, differentiated distributed components, and flexible buffering and spiral flow design of the components, achieving orderly material conveying while reducing material damage and jamming, and improving feeding efficiency and quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multi-stage flexible vibratory feeder hopper includes a vibrator, a connecting plate fixedly connected to the top outer wall of the vibrator, and a hopper body for conveying materials fixedly connected to the top of the connecting plate. The interior of the silo is equipped with multiple dispersion components for dispersing materials.

[0006] The above technical solutions can solve the problem of piling up thin, multi-faceted, and hook-shaped materials, enabling orderly material conveying, reducing material damage and jamming, and improving feeding efficiency and quality.

[0007] Preferably, the cross-section of the silo body is stepped, and the silo body includes a first stepped section, a second stepped section, and a third stepped section.

[0008] The above technical solutions can change the traditional straight-channel conveying mode of the feeding silo, allowing materials to fall step by step along the steps, avoiding the material from piling up and sliding down at once due to gravity. At the same time, each step can form an independent material temporary storage and dispersion space, creating conditions for subsequent differentiated dispersion processing, and structurally reducing the possibility of material agglomeration and accumulation.

[0009] Preferably, the dispersing components are distributed in an isosceles triangle on the first step and in a straight line on the second step.

[0010] Through the above technical solutions: the dispersion components can coarsely disperse large clumps of material from multiple angles, expand the dispersion coverage, and prevent material from clogging. At the same time, the second stage receives the coarsely dispersed material, and the linearly distributed dispersion components can finely sort the material, further breaking up small clumps of material that are not completely dispersed, ensuring that the dispersion of the material entering the third stage meets the standards.

[0011] Preferably, a partition is fixedly connected inside the hopper, and the partition is located directly above the second step.

[0012] The above technical solutions aim to prevent the dispersion components from failing to function properly due to material overload in the second step, while also preventing excessive material accumulation at the junction of the second and third steps, thus ensuring the smooth flow of materials along the steps.

[0013] Preferably, the dispersion component includes a fixed cylinder, a spring is fixedly connected to the bottom inner wall of the fixed cylinder, a circular plate is fixedly connected to the top of the spring, and a dispersion column is fixedly connected to the top outer wall of the circular plate.

[0014] Through the above technical solutions: the spring has elastic buffering capacity. When the material hits the dispersion column, the spring can drive the dispersion column to expand and contract adaptively through the circular plate, avoiding hard contact between the dispersion column and the material, which may cause material damage or bouncing. At the same time, the dispersion column is in direct contact with the material, and the material agglomeration is broken through the dual action of vibration and buffering.

[0015] Preferably, the end of the dispersion column away from the circular plate is provided with an arc-shaped portion, and the arc-shaped portion is hemispherical.

[0016] Through the above technical solutions: the hemispherical arc part can eliminate the sharp edges at the top of the dispersion column. When the material with hook-like structure comes into contact with the dispersion column, the arc part can guide the material to slide, avoiding the material with hook-like structure from getting caught on the dispersion column and causing the material to get stuck.

[0017] Preferably, the outer circumferential wall of the fixed cylinder is provided with a first guide groove.

[0018] The above technical solutions aim to guide the flow so that the material contacts the dispersion column more evenly, thereby improving the dispersion efficiency of the dispersion components and ensuring that no local congestion occurs during the material conveying process.

[0019] Preferably, the outer circumferential wall of the dispersion column is provided with a second guide groove, and both the first guide groove and the second guide groove are spiral-shaped.

[0020] Through the above technical solution: the spiral first guide channel and the second guide channel form a synergistic guiding effect. The material slides along the spiral trajectory under the action of vibration. On the one hand, it can prolong the contact time between the material and the dispersing component, so that the dispersion is more complete. On the other hand, the spiral trajectory can generate a gyratory force, which further disperses the stacked thin sheet material, realizes single-particle conveying, and reduces the friction between the material and the outer wall of the component, avoids scratches on the material surface, and ensures the quality of material conveying.

[0021] The beneficial effects of this utility model are as follows: In this invention, the synergistic effect of a stepped silo and differentiatedly distributed dispersing components effectively addresses the industry pain point of lumpy material feeding, particularly thin, multi-faceted, and hook-shaped materials. The stepped structure of the silo guides the material through progressive conveying. The dispersing components are arranged in isosceles triangles in the first step, efficiently coarsely dispersing large initial clumps of material and preventing material from clogging the conveying channel. Subsequently, they are arranged in a straight line in the second step, further refining the coarsely dispersed material. A baffle above the second step limits the conveying volume, preventing overloading of subsequent steps and ensuring uniform material dispersion and no accumulation throughout the conveying process, thus guaranteeing continuous material supply.

[0022] In this invention, the spring built into the dispersing component can adaptively extend and retract according to the impact force of the material. When the clump of material impacts the dispersing column, the spring drives the dispersing column to buffer and retract through the circular plate, preventing the material from bouncing or deforming due to hard resistance. At the same time, the hemispherical arc-shaped part at the top of the dispersing column can effectively avoid the problem of hook-shaped materials getting caught, reducing the frequency of material jamming. In addition, the spiral guide groove on the outer wall of the fixed cylinder and the dispersing column guides the material to slide along the spiral trajectory, greatly reducing the friction between the material and the component, avoiding scratches on the material surface. It is especially suitable for conveying precision thin sheet materials, ensuring the integrity of the material after conveying. Attached Figure Description

[0025] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0026] Reference Figures 1-4 A multi-stage flexible vibratory feeder hopper includes a vibrator 2, a connecting plate 5 fixedly connected to the top outer wall of the vibrator 2, and a hopper body 1 for conveying materials fixedly connected to the top of the connecting plate 5. The silo 1 is equipped with multiple dispersion components 3 for dispersing materials. The vibration energy generated by the vibrator 2 can be stably transmitted to the silo 1 through the connecting plate 5, providing a power basis for the material conveying in the silo 1. The dispersion components 3 inside the silo 1 can directly act on the materials, initially breaking the material agglomeration state and laying the foundation for subsequent orderly conveying. This can effectively solve the problem that traditional feeding silos rely on only a single vibration and lack a targeted dispersion structure.

[0027] To reduce the possibility of material agglomeration and accumulation, please refer to the appendix. Figure 1 , Figure 3 The cross-section of the silo 1 is stepped, and the silo 1 includes a first step, a second step and a third step. The stepped structure of the silo 1 (including the first step, the second step and the third step) can change the traditional straight channel conveying mode of the feeding silo, so that the material falls down step by step, avoiding the material from falling in a pile at once due to gravity. At the same time, each step can form an independent material temporary storage and dispersion space, creating conditions for subsequent differentiated dispersion processing, and structurally reducing the possibility of material agglomeration and accumulation.

[0028] To improve the dispersion effect of materials, refer to the appendix. Figure 3 The dispersion components 3 are distributed in an isosceles triangle on the first step and in a straight line on the second step. The dispersion components 3 adopt a differentiated distribution in different steps to adapt to the state of the material in different conveying stages. That is, the first step is the initial entry area of ​​the material. The dispersion components 3 distributed in an isosceles triangle can coarsely disperse large clumps of material from multiple angles, expand the dispersion coverage, and prevent material from clogging. At the same time, the second step receives the coarsely dispersed material. The straight-lined dispersion components 3 can finely sort the material and further break up the small clumps of material that are not completely dispersed, ensuring that the dispersion of the material entering the third step meets the standard.

[0029] In order to limit the flow of materials during the conveying process, please refer to the appendix. Figure 3 The internal structure of the silo 1 is fixedly connected to a partition 4, which is located directly above the second step. The partition 4 located directly above the second step can play a role in flow control, limiting the amount of material entering the second step from the first step, preventing the second step from being overloaded by material and causing the dispersion component 3 to not function fully, and preventing too much material from accumulating at the junction of the second step and the third step, thus ensuring the smooth conveying of material along the steps.

[0030] To address the issue of traditional rigid dispersion structures easily damaging materials, refer to the appendix... Figure 4 The dispersion component 3 includes a fixed cylinder 301. A spring 303 is fixedly connected to the bottom inner wall of the fixed cylinder 301. A circular plate 307 is fixedly connected to the top of the spring 303. A dispersion column 302 is fixedly connected to the top outer wall of the circular plate 307. The fixed cylinder 301 provides a stable installation base for the dispersion component 3. The spring 303 has elastic buffering capacity. When the material hits the dispersion column 302, the spring 303 can drive the dispersion column 302 to adaptively extend and retract through the circular plate 307, avoiding hard contact between the dispersion column 302 and the material, which would cause material damage or bouncing. At the same time, the dispersion column 302 is in direct contact with the material, and the material agglomeration is broken through the dual action of vibration and buffering.

[0031] To reduce the frequency of malfunctions during the material feeding process and improve equipment operational stability, please refer to the appendix. Figure 4 The end of the dispersion column 302 away from the circular plate 307 is provided with an arc-shaped part 306. The arc-shaped part 306 is hemispherical. The hemispherical arc-shaped part 306 can eliminate the sharp edges at the top of the dispersion column 302. When the material with hook-like structure comes into contact with the dispersion column 302, the arc-shaped part 306 can guide the material to slide, avoiding the material with hook-like structure from getting caught on the dispersion column 302 and causing the material to get stuck.

[0032] To improve the dispersion efficiency of the dispersion component 3 and ensure that no local congestion occurs during material conveying, please refer to the appendix. Figure 4 The outer circumferential wall of the fixed cylinder 301 is provided with a first guide groove 304. The first guide groove 304 can guide the material in the first step to flow orderly along the outer wall of the fixed cylinder 301, avoid the material from accumulating around the fixed cylinder 301, and at the same time, through the guiding effect, make the material contact the dispersing column 302 more evenly, improve the dispersing efficiency of the dispersing component 3, and ensure that no local congestion occurs during the material conveying process.

[0033] To further improve the dispersion uniformity and integrity of materials during the conveying process, and to avoid secondary agglomeration or surface damage to thin, layered materials due to disordered conveying trajectories, please refer to the appendix. Figure 4The outer circumferential wall of the dispersing column 302 is provided with a second guide groove 305. Both the first guide groove 304 and the second guide groove 305 are spiral in shape. The spiral first guide groove 304 and the second guide groove 305 form a synergistic guiding effect. Under the action of vibration, the material slides along the spiral trajectory. On the one hand, it can prolong the contact time between the material and the dispersing component 3, so that the dispersion is more complete. On the other hand, the spiral trajectory can generate a rotational force, further dispersing the stacked thin sheet material, realizing single-particle conveying, while reducing the friction between the material and the outer wall of the component, avoiding scratches on the material surface, and ensuring the quality of material conveying.

[0034] Working principle: When in use, the vibrator 2 will generate high-frequency vibration after starting. The vibration energy is transmitted to the chamber 1 with a stepped cross-section through the connecting plate 5, so that the material in the chamber 1 is conveyed down step by step along the first step, the second step and the third step. During the conveying process, multiple dispersing components 3 inside the chamber 1 play a core dispersing role. The fixed cylinder 301 of the dispersing component 3 provides stable support for the overall structure. The spring 303 inside it can adaptively extend and retract according to the impact force of the material. When the clump of material hits the dispersing column 302, the spring 303 drives the dispersing column 302 to buffer and retract through the circular plate 307, so as to avoid the material from bouncing or being damaged due to hard resistance. The hemispherical arc part 306 at the top of the dispersing column 302 can effectively avoid the problem of hook-shaped materials getting tangled, further reducing the risk of material jamming. Meanwhile, the dispersion component 3 is distributed in an isosceles triangle in the first step, which can efficiently disperse the initial large clumps of material and prevent the material from clogging the conveying channel. In the second step, it is distributed in a straight line, which can further refine the dispersion of the material after coarse dispersion. In conjunction with the partition 4 directly above the second step, the material conveying volume can be limited to avoid overloading of the material in the subsequent steps and ensure stable dispersion effect. Furthermore, the spiral first guide groove 304 on the outer circumference of the fixed cylinder 301 and the spiral second guide groove 305 on the outer circumference of the dispersing column 302 work together to guide the material along the spiral trajectory. This reduces frictional damage between the material and the components and further disperses the stacked material through the spiral guide. Ultimately, the material falls into the subsequent flexible vibrating plate in a single, undamaged state, which is convenient for the subsequent external industrial suction nozzle to accurately grasp it. This solves the defects of traditional feeding methods where thin sheet materials are piled up and cannot be properly conveyed and sorted, and greatly improves the feeding efficiency and material conveying quality.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
