Description

Technical Field

[0001] This utility model relates to the field of material handling technology, and more specifically, to a feeding device. Background Technology

[0002] In the field of battery material production, the feeding device plays an indispensable role as a key unloading equipment. The feeding device receives materials into its feeding space and then discharges the materials to the equipment below. Specifically, when the material in the hopper flows to the feeding device, the material can enter the space inside the feeding device and then be discharged in a measured amount as the internal rotation of the feeding device occurs.

[0003] However, the feeding volume of the feeding device is fixed, which limits its application under different production needs. Especially when production requires a lower feeding speed, simply adjusting the motor speed is insufficient, thus limiting the flexibility of the production line. In other words, when the feeding speed of the feeding device cannot meet production demands, companies often need to purchase or customize feeding devices with smaller volumes. This not only increases investment costs but also leads to production stoppages and affects production efficiency.

[0004] In other words, existing feeding devices have a fixed feeding volume, making it difficult to meet different feeding speed requirements. Utility Model Content

[0005] The main objective of this invention is to provide a feeding device to solve the problem that the fixed feeding volume of the feeding device in the prior art makes it difficult to meet the requirements of different feeding speeds.

[0006] To achieve the above objectives, this utility model provides a feeding device, which includes a housing with an inlet and an outlet. The feeding device also includes an impeller, which includes a shaft, blades, and spacers. The blades are spaced apart circumferentially along the shaft, and the spacers are located between adjacent blades. The spacers are detachably connected to the blades. The feeding device also includes a drive mechanism, which is drivenly connected to the shaft.

[0007] Furthermore, slots are provided on the blades, and spacers are inserted into the slots.

[0008] Furthermore, the housing includes a body and a side plate. The body has a disassembly port on one axial side of the rotating shaft. The side plate covers the disassembly port and is detachably connected to the housing. The slot is positioned facing the disassembly port.

[0009] Furthermore, the drive mechanism is located on the side of the body away from the disassembly port, and the drive mechanism passes through the body and is connected to the rotating shaft.

[0010] Furthermore, the spacer is spaced apart from the rotating shaft, and the spacer is in contact with two adjacent blades. The length of the spacer in the axial direction of the rotating shaft is greater than or equal to the length of the blade in the axial direction of the rotating shaft.

[0011] Furthermore, the two ends of the spacer along the axial direction of the rotating shaft are spaced at the same distance from the rotating shaft.

[0012] Furthermore, the spacer includes a first end and a second end disposed along the axial direction of the rotating shaft, wherein the distance between the first end and the rotating shaft is greater than the distance between the second end and the rotating shaft.

[0013] Furthermore, the spacer is a plate-like structure; or the spacer includes at least two connected plate-like members, with adjacent plate-like members arranged at an included angle.

[0014] Furthermore, the impeller is located between the feed inlet and the discharge outlet. Along the flow direction of the material, the opening area of ​​the feed inlet near the impeller end is smaller than the opening area away from the impeller end, and / or the opening area of ​​the discharge outlet near the impeller end is larger than the opening area away from the impeller end.

[0015] Furthermore, the inlet is located at the top of the housing, and the outlet is located at the bottom of the housing, with the inlet and outlet positioned opposite each other; or the inlet is located at the top of the housing, and the outlet is located on the side wall of the housing.

[0016] According to the technical solution of this utility model, the feeding device includes a housing with an inlet and an outlet; the feeding device also includes an impeller, which includes a shaft, blades and spacers, the blades are spaced apart circumferentially along the shaft, the spacers are located between two adjacent blades and the spacers are detachably connected to the blades; the feeding device also includes a drive mechanism, which is drivenly connected to the shaft.

[0017] The feeding device of this application has an inlet and an outlet on its housing to allow material in the upper hopper to enter and exit through the housing. An impeller with blades is installed inside the housing. The drive mechanism of the feeding device drives the impeller's shaft to rotate, which in turn drives the blades mounted on the shaft to rotate. The blades are spaced circumferentially along the shaft to provide landing points for the material, ensuring that the material falls evenly into the space between adjacent blades after entering the housing. Spacers are located between adjacent blades and are detachably connected to the blades. This arrangement reduces the volume between the blades, thereby reducing the amount of material passing through the impeller with each rotation. Furthermore, by inserting or removing the spacers, the feeding volume between adjacent blades can be flexibly adjusted to meet the feeding speed requirements of different products, greatly improving the applicability and production efficiency of the feeding device. In addition, the detachable design of the spacers not only facilitates daily maintenance and cleaning but also supports quick replacement, significantly reducing maintenance costs.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0034] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0035] To address the problem that the fixed feeding volume of existing feeding devices makes it difficult to meet different feeding speed requirements, this utility model provides a feeding device.

[0036] like Figures 1 to 11 As shown, the feeding device includes a housing 100, on which an inlet 11 and an outlet 12 are provided; the feeding device also includes an impeller 20, which includes a rotating shaft 21, blades 22 and spacers 23, the blades 22 are spaced apart circumferentially along the rotating shaft 21, the spacers 23 are located between two adjacent blades 22, and the spacers 23 are detachably connected to the blades 22; the feeding device also includes a drive mechanism 200, which is drivenly connected to the rotating shaft 21.

[0037] The feeding device of this application has an inlet 11 and an outlet 12 on its housing 100, allowing material in the upper hopper 400 to enter and exit through the housing 100. An impeller 20 with blades 22 is disposed inside the housing 100. The drive mechanism 200 of the feeding device can drive the rotating shaft 21 of the impeller 20 to rotate, thereby driving the blades 22 mounted on the rotating shaft 21 to rotate. The blades 22 are spaced circumferentially along the rotating shaft 21, providing landing points for the material so that the material, after entering the housing 100, can fall evenly into the space between adjacent blades 22. Spacers 23 are located between adjacent blades 22 and are detachably connected to the blades 22. This arrangement reduces the volume between the blades 22, thereby reducing the amount of material passing through the impeller 20 with each rotation. Furthermore, by inserting or removing the spacers 23, the feeding volume between adjacent blades 22 can be flexibly adjusted, thus meeting the feeding speed requirements of different products and greatly improving the applicability and production efficiency of the feeding device. In addition, the detachable design of the spacer 23 not only facilitates daily maintenance and cleaning, but also supports quick replacement, significantly reducing maintenance costs.

[0038] The aforementioned housing 100 comprises a main body 10 and a side plate 30. The inlet 11 and outlet 12 are both located on the main body 10, while the impeller 20 is located inside the main body 10, specifically in the space between the inlet 11 and outlet 12. This arrangement ensures that material continuously and evenly enters the feeding space between two adjacent blades 22 from the inlet 11, and then rotates with the blades 22 to the outlet 12. This enables precise metering and stable conveying of the material, preventing material accumulation or dead zones within the main body 10, which would affect the feeding speed. Furthermore, the side plate 30 provides support, reducing vibration of the main body 10 during high-speed rotation, thereby improving the operational stability and reliability of the feeding device. In some embodiments, the inlet 11 is located at the top of the main body 10, and the outlet 12 is located at the bottom of the main body 10.

[0039] exist Figures 2 to 4 In the illustrated embodiment, the main body 10 has a disassembly port 13 on one axial side of the rotating shaft 21, and the side plate 30 covers the disassembly port 13 and is detachably connected to the main body 10. Since the disassembly port 13 of the main body 10 is located on one axial side of the rotating shaft 21, the operator only needs to remove the side plate 30 to remove the spacer 23 from the disassembly port 13 side of the main body 10. This allows for replacement of the impeller 20, repositioning of the spacer 23, or inspection of the wear of internal components, facilitating timely replacement or maintenance and improving the flexibility and adaptability of the feeding device. Furthermore, the detachable side plate 30 makes the installation and removal of the spacer 23 more convenient, eliminating the need to disassemble the entire housing 100, reducing the time required for maintenance and adjustment, and improving production continuity.

[0040] exist Figure 1 , Figure 4In the illustrated embodiment, the drive mechanism 200 is located on the side of the body 10 away from the disassembly port 13, and passes through the body 10 to connect with the rotating shaft 21. The drive mechanism 200, located on the side of the body 10 away from the disassembly port 13, includes a motor and a reducer. The reducer of the drive mechanism 200 is connected to the body 10 via a flange structure 300. Positioning the disassembly port 13 and the drive mechanism 200 on opposite sides of the body 10 ensures the side plate 30 is removable while preventing interference between them, thus rationally distributing the maintenance area and the power area. The drive mechanism 200's connection to the rotating shaft 21 through the body 10 ensures efficient and stable power transmission.

[0041] Optionally, the side plate 30 is detachably connected to the body 10, including but not limited to bolt fixing and snap locking, to ensure a stable connection between the side plate 30 and the body 10 during operation, preventing material leakage, and facilitating disassembly when necessary. Furthermore, the edge of the side plate 30 has a sealing ring or sealing material to ensure a good seal when the side plate 30 covers the disassembly port 13, preventing material leakage from the disassembly port 13 or the introduction of dust contamination.

[0042] Optionally, the body 10 can be a hollow tube, or other geometric shapes can be selected according to actual production needs and space constraints, including but not limited to cylindrical, square, etc. The design of the body 10 shape must ensure that it matches the outer contour of the impeller 20 so that the material can flow smoothly in the gap of the impeller 20 without dead corners, while meeting the requirements of feeding volume and rate in different application scenarios.

[0043] Specifically, a slot 24 is provided on the blade 22, facing the disassembly port 13, and the spacer 23 is inserted into the slot 24. The slot 24 is fixedly set on the blade 22, so that the spacer 23 can be easily inserted or removed, and the slot 24 and spacer 23 remain stable during the feeding process. By setting the slot 24 on the blade 22 and inserting the spacer 23, the feeding space between two adjacent blades 22 can be reduced as needed, thereby controlling the feeding volume and achieving precise adjustment of the feeding speed; by setting the slot 24 facing the disassembly port 13, it is convenient for the operator to pull out or remove the spacer 23 from the slot 24 through the disassembly port 13, thereby improving the efficiency of installation and disassembly. In some embodiments, as long as it is possible to install or remove the spacer 23 in the slot 24 from the direction of the disassembly port 13, the shape of the slot 24 can be set accordingly.

[0044] like Figures 6 to 11In the specific embodiment shown, the spacer 23 is spaced apart from the rotating shaft 21, and the spacer 23 is in contact with two adjacent blades 22. The length of the spacer 23 in the axial direction of the rotating shaft 21 is greater than or equal to the length of the blade 22 in the axial direction of the rotating shaft 21. The spacer 23 is spaced apart from the rotating shaft 21, located within the space between two adjacent blades 22, and in close contact with these two adjacent blades 22. That is, changing the minimum distance between the spacer 23 and the rotating shaft 21 can change the size of the feeding space between two adjacent blades 22, thereby changing the total space between the spacer 23 and the inner wall of the body 10, ultimately achieving adjustment of the feeding volume.

[0045] Along the axial direction of the rotating shaft 21, the length of the spacer 23 is greater than or equal to the length of the blade 22. This arrangement ensures that when the spacer 23 is inserted into the slot 24, it can completely cover the space between adjacent blades 22, preventing material on the spacer 23 from leaking into the space between the spacer 23 and the rotating shaft 21 and forming stagnation in that space, thereby improving the utilization efficiency of the material.

[0046] Optionally, the spacer 23 can be a plate-like structure. The spacer 23 is not limited to a single plate-like structure; it can also consist of at least two connected plate-like components, with adjacent plate-like components arranged at an included angle. The spacer 23, composed of multiple plate-like components, not only allows for flexible configuration adjustments as needed but also better adapts to different material characteristics, expanding the applicability of the feeding device. The included angle between two adjacent plate-like components can be from 90° to 270°.

[0047] Preferably, the included angle between two adjacent plate-shaped members can be 90°, 100°, 120°, 150°, 180°, 210°, 240°, 260°, 270°, or any angle between them.

[0048] Furthermore, in high-dust environments, to ensure the cleanliness of the feeding space and stabilize the position of the spacer 23, the blade 22 and the spacer 23 can be fixed by using threads. Through the pre-designed threaded interface, the spacer 23 can be securely screwed in or out, preventing loosening caused by high-dust environments. The threaded connection also facilitates regular maintenance and cleaning.

[0049] Optionally, the spacer 23 can be made of stainless steel, titanium, plastic, etc.

[0050] Optionally, the inlet 11 and outlet 12 can be openings only on the main body 10, or they can be guide pipes with an extended distance. The guide pipes are connected to the interior of the main body 10, which facilitates smooth material entry and efficient discharge, reduces the risk of blockage during unloading, and enhances the operational stability and reliability of the feeding device. Furthermore, the guide pipes can be configured according to the spatial layout of the production process, flexibly connecting to other equipment on the production line, improving the integration and automation level of the production line.

[0051] It should be noted that when the inlet 11 and outlet 12 are guide pipes with an extended distance, their diameters can be the same or different. When the diameters of the inlet 11 and outlet 12 are different, one or both of the following configurations can be included. Specifically, one configuration is that, along the material flow direction, the opening area of ​​the inlet 11 near the impeller 20 can be smaller than the opening area away from the impeller 20; another configuration is that the opening area of ​​the outlet 12 near the impeller 20 can be larger than the opening area away from the impeller 20. Adjusting the opening areas of the inlet 11 and outlet 12 can control the material entry and discharge speeds.

[0052] In other words, when the opening area of ​​the feed inlet 11 near the impeller 20 is smaller than the opening area away from the impeller 20, the diameter of the feed inlet 11 gradually decreases as the material approaches the impeller 20. This arrangement helps to slow down the speed at which the material enters the body 10, especially when the impeller 20 is rotating at high speed, preventing excessive material from rushing in at once, causing blockages or affecting the uniform discharge of the impeller 20. Conversely, the opening area of ​​the discharge outlet 12 near the impeller 20 is larger than the opening area away from the impeller 20 to ensure that the material can leave the discharge space smoothly and quickly, avoiding accumulation or stagnation at the discharge outlet 12.

[0053] like Figure 5 In one embodiment shown, the feed inlet 11 is connected to the upstream silo 400, and a valve is installed between the feed inlet 11 and the silo 400 to reasonably control the material discharge speed. The discharge outlet 12 of the feeding device is connected to the downstream receiving equipment for further processing of the material.

[0054] In some alternative embodiments, such as Figure 1As shown, the feed inlet 11 is located at the top of the body 10, and the discharge outlet 12 is located at the bottom of the body 10, with the feed inlet 11 and discharge outlet 12 positioned opposite each other. Along the axial direction perpendicular to the rotating shaft 21, the highest point or near the highest point of the body 10 is the top of the body 10, and the feed inlet 11 is located at the top of the body 10. At this point, the material enters vertically from above the body 10, utilizing gravity to accelerate the material flow. Along the axial direction perpendicular to the rotating shaft 21, the lowest point or near the bottom of the body 10 is the bottom of the body 10. At this point, the material rotates through the gaps in the impeller 20 to the bottom and is discharged vertically. This arrangement effectively utilizes natural gravity, reduces the resistance to material flow, and improves unloading efficiency.

[0055] In one embodiment (not shown), the feed inlet 11 is located at the top of the body 10, and the discharge outlet 12 is located on the side wall of the body 10. The side wall of the body 10 forms a certain angle with the axial direction of the rotating shaft 21. With the discharge outlet 12 located on the side wall of the body 10, the material can flow out at an angle along the side wall after entering vertically from above the body 10. This arrangement ensures a smoother outflow path, reduces unnecessary dwell time within the body 10, reduces the workload of the drive mechanism 200, thereby saving energy consumption and improving the efficiency of the entire feeding device.

[0056] Optionally, the included angle between the sidewall portion and the axial direction of the rotating shaft 21 can be set to 45° to 85°. Preferably, the included angle between the sidewall portion and the axial direction of the rotating shaft 21 can be set to 45°, 55°, 65°, 75°, 85°, and any angle in between.

[0057] Optionally, the impeller 20 can be equipped with multiple sets of slots 24 and matching spacers 23 as needed to provide more options for discharge volume.

[0058] Example 1

[0059] like Figures 6 to 7 The image shows an embodiment of the spacer 23 in the feeding device. The spacer 23 has a plate-like structure, and the two ends of the spacer 23 along the axial direction of the rotating shaft 21 are spaced at the same distance from the rotating shaft 21.

[0060] In Embodiment 1, there are multiple spacers 23, which adopt a cuboid plate structure. Along the axial direction of the rotating shaft 21, the two ends of the spacers 23 are spaced equidistant from the rotating shaft 21. This arrangement ensures that each spacer 23 is centered when inserted between two adjacent blades 22, and that the spacers 23 can evenly divide the space between two adjacent blades 22. In other words, the feeding space between each pair of adjacent blades 22 is consistent, thereby achieving uniform feeding.

[0061] In addition, such as Figure 7As shown, in Embodiment 1, the distance between the slot 24 on the blade 22 and the rotating shaft 21 is the same. A single slot 24 is formed by two spaced triangular plates fixed to the blade 22. This spacer is adapted to the thickness of the spacer 23 to prevent displacement during rotation. When disassembly or maintenance is required, the spacer 23 can be removed from the disassembly port 13 side of the body 10.

[0062] Example 2

[0063] In one embodiment not shown, a second embodiment of the spacer 23 of the feeding device is described. The difference between the second embodiment and the first embodiment is that the distances between the slots 24 on both sides of the blade 22 and the rotating shaft 21 are different.

[0064] In Embodiment 2, the distance between the connection point of a single spacer 23 on two adjacent blades 22 and the rotating shaft 21 is different, in order to meet the material feeding volume and material feeding flow rate required for production.

[0065] Example 3

[0066] like Figures 8 to 9 The image shows a third embodiment of the spacer 23 in the feeding device. The difference between the third embodiment and the first embodiment is that the spacer 23 includes a first end 211 and a second end 212 arranged along the axial direction of the rotating shaft 21. The distance between the first end 211 and the rotating shaft 21 is greater than the distance between the second end 212 and the rotating shaft 21.

[0067] In Embodiment 3, along the axial direction of the rotating shaft 21, the first end 211 of the spacer 23 is closer to the disassembly port 13 than the second end 212, and the distance between the second end 212 and the rotating shaft 21 is smaller than the distance between the first end 211 and the rotating shaft 21. In the feeding space between two adjacent blades 22, the feeding space of the second end 212 is larger than that of the first end 211. When the material falls from the top feed port 11 to the position of the second end 212, a relatively large feeding space is formed due to the larger distance between the second end 212 and the rotating shaft 21; when the material falls from the top feed port 11 to the position of the first end 211, the feeding space is correspondingly smaller because the distance between the first end 211 and the rotating shaft 21 is smaller. This arrangement results in different discharge velocities of the material at the discharge port 12, thereby achieving non-uniform feeding.

[0068] Example 4

[0069] like Figures 10 to 11 The image shows a fourth embodiment of the spacer 23 in the feeding device. The difference between the fourth embodiment and the first embodiment is that the spacer 23 consists of two connected plate-shaped members, with adjacent plate-shaped members arranged at a 90° angle.

[0070] In embodiment four, the right-angled design of the spacer 23 can better utilize the feeding space between two adjacent blades 22. Compared with the plate structure, the spacer 23 has an outwardly protruding right angle, which can divide the feeding space between two adjacent blades 22, thereby effectively blocking the material flow and slowing down the feeding speed.

[0071] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0072] 1. The feeding device of this application has an inlet 11 and an outlet 12 on its housing 100, so that the material in the upper hopper 400 can enter and exit through the housing 100. An impeller 20 with blades 22 is disposed inside the housing 100. The drive mechanism 200 of the feeding device can drive the rotating shaft 21 of the impeller 20 to rotate, thereby driving the blades 22 sleeved on the rotating shaft 21 to rotate. The blades 22 are spaced apart circumferentially along the rotating shaft 21 to provide landing points for the material, so that the material can fall evenly in the space between two adjacent blades 22 after entering the housing 100.

[0073] 2. The spacer 23 is located between two adjacent blades 22 and is detachably connected to the blades 22. This arrangement can reduce the volume between the blades 22, thereby reducing the amount of material passing through the impeller 20 each time it rotates. The material discharge volume between two adjacent blades 22 can also be flexibly adjusted by inserting or removing the spacer 23, thereby meeting the material discharge speed requirements of different products and greatly improving the applicability and production efficiency of the material discharge device.

[0074] 3. The detachable design of the spacer 23 not only facilitates daily maintenance and cleaning, but also supports quick replacement, significantly reducing maintenance costs.
