Description

Technical Field

[0001] This invention relates to a vibratory feeder based on a multi-stage dust reduction and wear-resistant design, belonging to the technical field of automated feeding equipment. Background Technology

[0002] Vibratory feeders are widely used material sorting and conveying equipment in automated production and assembly lines. They rely on vibration to achieve orderly feeding and directional conveying of small materials and are commonly used in industries such as hardware, electronics, and precision machining.

[0003] Existing vibratory feeders lack a complete dust collection and guidance structure. Dust is conveyed synchronously with the material and is difficult to detach from the material conveying path on its own, which easily leads to dust backflow and secondary adhesion to the material. Some simple dust removal structures can only achieve local dust cleaning and cannot achieve full-process, multi-stage dust separation. Dust scattering can also pollute the working environment and endanger operational safety. Furthermore, there is no pre-dust removal in the feeding stage, which increases the dust removal load of subsequent dust removal. The feeding structure of conventional feeders only has a single feeding function. Dust generated during the feeding and initial conveying process cannot be removed in advance and directly enters the vibratory feeder body, greatly increasing the dust removal pressure of the main equipment and resulting in a significant reduction in the overall dust reduction effect.

[0004] Therefore, there is an urgent need to improve a vibratory feeder device based on multi-stage dust reduction and wear prevention design to solve the above-mentioned problems. Summary of the Invention

[0006] The vibrating material conveying mechanism includes a vibrating plate and a vibrating material tray. The vibrating plate is fixedly installed on the upper end of the vibrating material tray. A spiral track is fixedly installed on the inner side wall of the vibrating plate. Several evenly distributed spiral track dust leakage ports are opened on the spiral track. A threaded ball groove is opened at the bottom end of the vibrating plate. The threaded ball groove is distributed in a tornado-shaped spiral trajectory around the center of the vibrating plate. The groove gradually extends from the center to the outside. A threaded ball groove leakage port is opened at the end of the threaded ball groove away from the center of the vibrating plate. The threaded ball groove leakage port penetrates the bottom end of the vibrating plate.

[0007] Preferably, a tapered dust storage tray is fixedly installed inside the vibrating material tray, and a plurality of vacuum dust discharge holes are opened at the bottom end of the tapered dust storage tray. The vacuum dust discharge holes penetrate through the outside of the vibrating material tray, and a vibrating material seat is fixedly installed at the bottom end of the vibrating material tray. The vibrating material seat is fixedly installed on the equipment base.

[0008] Preferably, the vibratory feeder has a discharge port on one side of the upper port, and a conveying component is fixedly installed on the outside of the discharge port. The conveying component has a U-shaped mesh groove, which is located at one end of the discharge port.

[0009] Preferably, an air blowing component is fixedly installed on the outside of the material conveying component, and the air blowing component is located on the outside of the U-shaped mesh channel.

[0010] Preferably, the feeding mechanism includes a column fixing base and a fixing column. The column fixing base is fixedly installed on the equipment base, and the fixing column is fixedly installed on the column fixing base. A lower adjustment component is fixedly installed on the fixing column by bolts, and the lower adjustment component is located above the column fixing base.

[0011] Preferably, a feeding mechanism fine-tuning bracket is fixedly installed on the lower adjusting member, and a feeding trough is slidably installed on the feeding mechanism fine-tuning bracket.

[0012] Preferably, an upper adjusting component for the feeding hopper is fixedly installed on the fixed column by bolts. The upper adjusting component for the feeding hopper is located above the lower adjusting component. A feeding hopper is fixedly installed on the upper adjusting component for the feeding hopper, and the material leakage hole of the feeding hopper is located inside the feeding trough.

[0013] Preferably, the bottom of the feeding trough is provided with a plurality of evenly distributed dust leakage holes, the dust leakage holes are located at the end away from the discharge hopper, a dust storage device is fixedly installed at the bottom of the feeding trough, the dust storage device is located below the dust leakage holes, and a plurality of dust discharge holes are provided on one side of the dust storage device.

[0014] Preferably, a discharge guide groove is rotatably installed at one end of the feeding trough, and the discharge guide groove is located at one end of the dust leakage hole.

[0015] Preferably, a plurality of leveling feet are fixedly installed at the bottom of the equipment base, and the leveling feet are evenly distributed at the four right angles of the equipment base.

[0016] This invention has at least the following beneficial effects:

[0017] 1. This invention uses a spiral trajectory design with a tornado-shaped threaded ball groove at the bottom of the vibratory plate, which is highly compatible with the vibration direction of the vibratory plate. It can quickly collect dust at the bottom of the plate and achieve rapid material discharge with the threaded ball groove discharge port. There are no dead corners with dust residue. The overall dust removal structure relies on the vibration operation of the equipment itself, without the need for additional complex power. The equipment operates stably and has high dust removal efficiency.

[0018] 2. This invention adopts a five-stage dust removal structure, including pre-dust removal before feeding, track dust blocking, bottom-guided dust removal, negative pressure active dust collection, and end-of-pipe airflow purging. It treats dust in stages throughout the entire process from feeding and conveying to discharging, completely blocking the path of dust conveying, accumulation and secondary adhesion, eliminating dust leakage and pollution, and greatly improving the cleanliness of the discharged material to meet the environmental protection requirements of precision feeding.

[0019] 3. The present invention is equipped with a U-shaped mesh channel and an air blowing component at the discharge end to achieve precise blowing of residual dust on the surface of the material, thoroughly remove adhering dust, ensure the cleanliness of the discharged material, avoid dust affecting the accuracy of subsequent processing and assembly, and improve the product qualification rate of the entire production line.

[0020] 4. This invention achieves sealed dust collection through a tapered dust storage tray and dust storage components. Combined with a vacuum dust discharge port and a dust discharge port, dust can be discharged quickly and centrally without the need for frequent manual cleaning of the tray. There are no dust residue dead corners, reducing the difficulty of daily equipment maintenance and optimizing the production operation environment.

[0021] 5. This invention uses POM engineering plastic balls of suitable specifications as a buffer medium to fill the gaps between workpieces. The plastic balls have an appropriate diameter and fall back into the vibratory feeder through a spiral rail that climbs at an angle along the side wall of the vibratory feeder. During the vibration conveying process, they replace the rigid contact between workpieces, absorb vibration collision energy, and significantly reduce secondary wear, chipping, and scratches on the workpieces. At the same time, they eliminate the new dust generated by hard friction of the workpieces, achieving the dual effects of wear prevention and dust suppression. Attached Figure Description

[0033] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0034] like Figures 1-8 As shown, a vibratory feeder based on multi-stage dust reduction and wear prevention design includes a base 1, a vibratory material conveying mechanism 3 fixedly installed on the upper surface of the base 1, and a feeding mechanism 2 fixedly installed on the upper surface of the base 1, with the feeding mechanism 2 located on one side of the vibratory material conveying mechanism 3.

[0035] The vibrating material conveying mechanism 3 includes a vibrating plate 4 and a vibrating material tray 10. The vibrating plate 4 is fixedly installed on the upper end of the vibrating material tray 10. A spiral track 5 is fixedly installed on the inner side wall of the vibrating plate 4. Several evenly distributed spiral track dust leakage ports 8 are opened on the spiral track 5. A threaded ball groove 7 is opened at the bottom end of the vibrating plate 4. The threaded ball groove 7 is distributed in a tornado-shaped spiral trajectory around the center position of the vibrating plate 4. The groove gradually extends from the center to the outside. A threaded ball groove leakage port 6 is opened at the end of the threaded ball groove 7 away from the center position of the vibrating plate 4. The threaded ball groove leakage port 6 penetrates the bottom end of the vibrating plate 4.

[0036] Thus, when this vibratory feeder, based on a multi-stage dust reduction and wear-resistant design, is in operation, the equipment base 1 serves as the overall support base. The feeding mechanism 2 completes the feeding operation of the products to be conveyed, sending the products into the vibratory conveying mechanism 3 on one side for continuous feeding. The vibratory conveying mechanism 3 supports the top vibratory feeder 4 through the vibratory tray 10, providing vibration driving force to the vibratory feeder 4 and driving the products to achieve spiral feeding and conveying. The equipment achieves dust source suppression through source friction reduction and dust reduction layer. The surface and internal sidewalls of the vibratory feeder 4 are made of special materials with high hardness and high wear resistance, and all surfaces in contact with the products are treated with ultra-precision polishing, with the surface roughness controlled below Ra0.2μm, significantly reducing the coefficient of friction and reducing frictional dust generation from the root. At the same time, during the vibration and climbing process, the products in the vibratory feeder 4 are mixed with POM engineering plastic balls of appropriate diameter, filling the gaps between products, buffering hard collisions between products, reducing collision wear and new dust generation. Under the action of the component spiral track 5, the conveyor rises spirally. It relies on the track-level dust blocking, separation and online cleaning system to achieve secondary dust removal. The spiral track dust leakage port 8 opened on the component spiral track 5 forms a dust blocking structure, interrupting the path of dust rising with the product and forcing the dust to fall to the bottom of the tray. The small ball grooves on the side wall of the track use the difference in size, mass and inertia between the product and the dust to achieve physical separation of the product and the dust, reducing secondary dust adhesion. In conjunction with the compressed air blowing port to blow the surface of the product, the residual dust adhering is removed. The dust falling to the bottom of the vibrating plate 4 achieves primary dust removal through the tray-level dust guiding and collection system. The spirally distributed spiral ball grooves 7 at the bottom of the tray are adapted to the vibration direction to guide the dust flow and quickly discharge it through the end spiral ball groove leakage port 6. The vibrating tray 10 below the vibrating plate 4 serves as a sealed tray. Its internal negative pressure dust suction device generates negative pressure airflow to suck away the dust falling from the leakage port in time, realizing active and continuous dust collection.

[0037] Furthermore, such as Figures 2-6 As shown; a tapered dust storage tray 12 is fixedly installed inside the vibrating tray 10. Several vacuum dust discharge holes 13 are opened at the bottom of the tapered dust storage tray 12. The vacuum dust discharge holes 13 penetrate through the outside of the vibrating tray 10. A vibrating seat 11 is fixedly installed at the bottom of the vibrating tray 10. The vibrating seat 11 is fixedly installed on the equipment base 1. A discharge port 9 is opened on one side of the upper port of the vibrating plate 4. A conveying component 14 is fixedly installed on the outside of the discharge port 9. A U-shaped mesh groove 16 is opened on the conveying component 14. The U-shaped mesh groove 16 is located at one end of the discharge port 9. An air blowing component 15 is fixedly installed on the outside of the conveying component 14. The air blowing component 15 is located outside the U-shaped mesh groove 16.

[0038] Thus, as the material rises along the spiral conveyor track, the dust at the bottom of the tray is directed along the spirally distributed threaded ball grooves 7, and finally discharged downwards from the threaded ball groove discharge port 6, falling into the tapered dust storage tray 12 inside the vibrating tray 10. The tapered dust storage tray 12, in conjunction with an external negative pressure dust extraction system, actively sucks out and collects the dust through the vacuum dust discharge port 13 at its bottom, achieving a closed-loop dust discharge and preventing dust leakage and backflow. The material is then conveyed via the spiral conveyor track to… The material enters the discharge port 9 at the upper end of the vibratory feeder 4 and then enters the conveying component 14 outside the discharge port 9. It continues to be conveyed along the U-shaped mesh trough 16 on the conveying component 14. At this time, the air blowing component 15 outside the conveying component 14 is activated, spraying high-pressure airflow onto the material surface in the U-shaped mesh trough 16. Combined with electrostatic neutralization and technology, the static electricity on the material surface is eliminated, the magnetic adsorption force of dust is broken, and the residual dust on the material surface is blown off. The dust falls off and is discharged through the holes of the U-shaped mesh trough 16, further completing the online cleaning of the material end.

[0039] Furthermore, such as Figures 7-8 As shown; the feeding mechanism 2 includes a column fixing base 21 and a fixing column 19. The column fixing base 21 is fixedly installed on the equipment base 1, and the fixing column 19 is fixedly installed on the column fixing base 21. A lower adjusting component 20 is fixedly installed on the fixing column 19 by bolts. The lower adjusting component 20 is located above the column fixing base 21. A feeding mechanism fine-tuning bracket 24 is fixedly installed on the lower adjusting component 20, and a feeding trough 22 is slidably installed on the feeding mechanism fine-tuning bracket 24. An upper adjusting component 18 for the feeding hopper is fixedly installed on the fixing column 19 by bolts. The upper adjusting component 18 for the feeding hopper is located above the lower adjusting component 20, and a feeding hopper 1 is fixedly installed on the upper adjusting component 18 for the feeding hopper 1. 7. The material discharge hole of the hopper 17 is located inside the feeding trough 22. Several evenly distributed dust discharge holes 26 are opened at the bottom of the feeding trough 22. The dust discharge holes 26 are located at the end away from the hopper 17. A dust storage component 27 is fixedly installed at the bottom of the feeding trough 22. The dust storage component 27 is located below the dust discharge holes 26. Several dust discharge holes 28 are opened on one side of the dust storage component 27. A discharge guide groove 23 is rotatably installed at one end of the feeding trough 22. The discharge guide groove 23 is located at one end of the dust discharge holes 26. Several horizontal adjustment cups 25 are fixedly installed at the bottom of the equipment base 1. The horizontal adjustment cups 25 are evenly distributed at the four right angles of the equipment base 1.

[0040] Thus, this device is a vibratory feeder based on multi-stage dust reduction and wear prevention design. The four corners of the bottom of the equipment base 1 are evenly equipped with leveling feet 25, which can finely adjust and correct the overall level of the machine, ensuring stable operation and preventing material swaying, severe friction, and dust generation caused by machine tilt. This provides a basic support for stable material feeding. A feeding mechanism 2 is fixedly installed on the equipment base 1. The feeding mechanism 2 is fixed to the upper surface of the equipment base 1 via a column fixing seat 21. A fixing column 19 is fixedly connected to the upper end of the column fixing seat 21. A lower adjusting component 20 and an upper adjusting component 18 of the discharge hopper are bolted to the outside of the fixing column 19. The upper adjusting component 18 of the discharge hopper is adjusted upwards... The section 18 is arranged above the lower adjusting member 20. The upper adjusting member 18 has a fixedly installed feeding hopper 17 at its end. The discharge end of the feeding hopper 17 extends into the feeding trough 22, allowing the material to fall quantitatively into the feeding trough 22. The upper end of the lower adjusting member 20 is fixedly equipped with a feeding mechanism fine-tuning bracket 24. The feeding trough 22 is slidably mounted on the feeding mechanism fine-tuning bracket 24, allowing for fine-tuning of its front and rear positions. It can precisely adjust the feeding position and feeding stroke according to the workpiece specifications, adapting to different material conveying needs. During the sliding conveying of material inside the feeding trough 22, floating dust and processing debris adhering to the workpiece surface can pass through the dust leakage holes 26 evenly opened at the bottom of the feeding trough 22. As the material falls downwards, the dust passes through the dust leakage hole 26 and falls into the dust storage unit 27 at the bottom for centralized collection. Several dust discharge holes 28 are provided on the side wall of the dust storage unit 27 to discharge the accumulated dust uniformly, achieving pre-dust removal during front-end feeding and reducing dust and impurities brought into the vibrating plate 4 at the source. The discharge end of the feeding trough 22 is rotatably equipped with a discharge guide groove 23. After the material passes through the dust leakage hole 26 for dust removal, it is guided by the discharge guide groove 23 into the vibrating plate 4, preventing material scattering and splashing, ensuring orderly and stable feeding. When starting the formal vibrating feeding operation, an appropriate amount of PO with a matching diameter is added to the vibrating plate 4. M-type polyoxymethylene (POM) engineering plastic balls enter the conveying process along with the workpiece and fall completely back into the vibratory feeder 4. During the high-frequency vibration feeding process of the vibratory feeder 4, the POM balls fill the gaps between workpieces and between workpieces and equipment structures. Utilizing their own highly lubricating and highly tough flexible media properties, they absorb and buffer the hard collision impact force generated between workpieces, avoiding direct rigid impact, squeezing and friction of workpieces, greatly reducing bumping wear and scratches during workpiece conveying, and effectively suppressing the new dust generated by workpiece collision and friction. Combined with the pre-dust removal structure of the front-end feeding mechanism 2, a multi-stage dust reduction and two-way anti-wear working mechanism is formed.

[0041] The principle of the vibratory feeder based on multi-stage dust reduction and wear prevention design provided in this embodiment is as follows: When the equipment is running, the material falls from the discharge hopper 17 into the feeding trough 22. The upper adjustment component 18 and the lower adjustment component 20 of the discharge hopper can precisely adjust the position of the discharge hopper 17 and the feeding trough 22 to control the feeding amount. A dust leakage hole 26 is opened at the bottom of the feeding trough 22. During the material conveying process, the floating dust and processing debris attached to the surface of the material will fall into the dust storage component 27 below through the dust leakage hole 26 and be discharged through the dust discharge hole 28, completing the first stage of pre-dust removal. At the same time, a certain amount of POM (polyoxymethylene) balls are put into the vibratory feeder 4. The balls fill the gaps between the workpieces in advance to prevent dust accumulation during vibration. The process is buffered to prevent collisions; the discharge guide trough 23 can guide the material to avoid feeding, scattering, and dust generation, further reducing dust diffusion. After the material enters the vibrating plate 4, it is conveyed upward along the spiral track 5 under vibration drive. The dust leakage port 8 on the spiral track will directly leak the dust and debris that falls off during the conveying process, realizing the second stage of track dust removal; the bottom of the vibrating plate 4 is equipped with a tornado-shaped spiral ball groove 7, which extends outward from the center. The diameter of the POM small balls that convey the falling dust and debris is larger than the spiral ball groove 7 at the bottom of the vibrating plate 4 and the dust leakage port 8 on the spiral track. The small balls fall back and remain in the vibrating plate 4, and are collected by negative pressure through the vacuum dust discharge hole 13, completing the third stage of bottom dust removal. Dust; POM engineering plastic balls mixed in with the material are evenly filled in the gaps between workpieces and between workpieces and the inner wall of the vibrating plate 4. When the vibrating plate 4 generates high-frequency vibration, the impact force generated by the direct rigid collision and friction of the workpieces will be absorbed and buffered by the flexible POM balls, avoiding surface wear and chipping caused by hard impact of the workpieces, thus reducing the generation of dust from the source; at the same time, after the dust content is reduced, it can avoid dust particles being trapped between workpieces and aggravating friction and wear, realizing the dual function of dust control and workpiece protection. The material is conveyed along the spiral track 5 to the discharge port 9 and enters the U-shaped mesh trough 16 of the conveying component 14. The fine dust remaining in the material can be leaked out through the mesh trough; outer side The air blowing component 15 blows air in a directional manner to remove residual dust from the surface of the workpiece, completing the fourth stage of end dust removal. Finally, clean and low-wear workpieces are stably discharged. The vibrating tray 10 and vibrating seat 11 stably support the vibrating plate 4. The horizontal adjustment cups 25 of the equipment base 1 can adjust the level of the equipment to ensure stable vibration and avoid the equipment tilting, which will aggravate the collision and wear of the material. The tapered dust storage tray 12 and each leakage hole form a closed-loop dust collection channel, and the dust is discharged in a concentrated manner without secondary dust. With the help of the POM ball buffer system, multi-stage dust reduction and dual-dimensional wear prevention are achieved. This not only reduces the frictional damage of dust to the workpiece, but also inhibits collision and wear through the flexible buffer medium, thereby improving the quality of the workpiece and the service life of the equipment.
