Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, specifically a handwheel-type feeder. Background Technology

[0002] In the production and manufacturing process of lithium batteries, the precise selection of positive and negative electrode materials is one of the key links to ensure battery performance and quality. These materials usually have fine particle size and special physicochemical properties, which places high demands on the stability, accuracy and ease of operation of the material selection process.

[0003] Currently, the lithium battery positive and negative electrode material feeders widely used in the industry generally adopt a pull-out structure. This type of feeder has significant inconveniences in actual operation. Because the pull-out action requires the operator to apply considerable pushing or pulling force, and the lack of effective guiding and limiting mechanisms during the process makes it prone to jamming, tilting, and other problems, increasing the operator's workload and making it difficult to accurately control the amount of material picked up. At the same time, the pull-out structure has poor sealing performance, which can easily lead to material spillage and dust generation during the feeding process, resulting in material waste, potentially affecting the cleanliness of the production environment, and even posing a potential threat to the health of operators. In addition, frequent pull-out operations will accelerate the wear and tear of components, shorten the feeder's service life, and increase equipment maintenance costs.

[0004] Therefore, developing a feeder that is easy to operate, accurate in picking materials, and has good sealing performance has become an urgent need to solve the current problem of picking positive and negative electrode materials for lithium batteries. Utility Model Content

[0005] To address the problems in related technologies, this utility model provides a handwheel-type feeder, which solves the problems of jamming, tilting, and difficulty in operation that easily occur during the sampling process.

[0006] To solve the above problems, the following technical solutions are provided:

[0007] This utility model's handwheel-type feeder includes a first cylinder body disposed on one side of a discharge cylinder. A lead screw is disposed inside the first cylinder body, and a helical blade is fixedly disposed on the outer circumferential surface of the lead screw. An annular notch is provided on the outer circumferential surface of the lead screw near the end of the discharge cylinder. A bushing is rotatably connected to the outer circumferential surface of the lead screw corresponding to the annular notch. A sealing plate is fixedly sleeved on the outside of the bushing. A feed plate is disposed below the lead screw, and the sealing plate is fixedly connected to the feed plate. A nut is disposed on the side of the lead screw near the discharge cylinder, and the nut abuts against the outer wall surface of the sealing plate. A hopper is connected to the bottom of the first cylinder body. A drive mechanism is disposed on the side of the lead screw away from the discharge cylinder so that the lead screw can extend into the discharge cylinder.

[0008] In the above solution, the material-receiving plate and spiral blades are used. The drive mechanism drives the lead screw and the material-receiving plate to extend into the discharge cylinder, and at the same time drives the lead screw to rotate. The material-receiving plate can pick up the material, and the spiral blades are used to transport the material. The operation is more labor-saving and convenient. The cooperation of the bushing, sealing plate and nut enhances the sealing performance of the feeder and limits the sealing plate, reducing the spillage and dust of material during the feeding process. This avoids material waste and maintains the cleanliness of the production environment. The hopper connected to the bottom of the first cylinder can collect the transported material in time, thus solving the problems of jamming, tilting and difficulty in operation that easily occur during the sampling process of the feeder.

[0009] The drive mechanism includes a threaded rod and a threaded sleeve. The threaded sleeve is sleeved around the threaded rod and the threaded sleeve and the threaded rod are in a rotatable engagement. A connecting shaft is fixed between the threaded sleeve and the lead screw. A handle is provided at the end of the threaded rod away from the connecting shaft.

[0010] The above solution improves operational convenience by using a threaded rod and threaded sleeve in conjunction with a handle drive. Operators can rotate the threaded rod by turning the handle, which in turn drives the lead screw through the threaded sleeve and connecting shaft. The transmission is smooth and labor-saving. Compared with the direct force application of traditional pull-out structures, the strength is significantly reduced. This rotary drive mechanism makes the extension and retraction control of the lead screw more precise, allowing operators to accurately adjust the length of the lead screw extending into the discharge cylinder according to actual needs, thereby better controlling the amount of material taken out and improving the controllability of the material taking process.

[0011] The threaded sleeve is connected to a second cylindrical body, the inner wall of the second cylindrical body abuts against the outer wall of the threaded sleeve, and the end of the second cylindrical body away from the handle is fixedly connected to the end of the first cylindrical body near the connecting shaft.

[0012] In the above solution, the second cylinder is fixedly connected to the first cylinder, and its inner wall abuts against the outer wall of the threaded sleeve. This provides stable support and guidance for the threaded sleeve, enhances the structural stability of the drive mechanism, prevents the threaded sleeve from shaking or deviating during rotation, ensures the smoothness of the transmission between the threaded rod and the threaded sleeve, and thus guarantees the stability of the screw extension and material conveying. Furthermore, the second cylinder protects the threaded sleeve, reduces interference from the external environment on the drive mechanism, and extends the service life of the feeder.

[0013] The hopper is fixedly connected to the first cylinder, and a receiving cylinder is provided below the hopper. The hopper and the receiving cylinder are detachably connected.

[0014] In the above solution, the hopper is fixedly connected to the first cylinder by the setting of the receiving cylinder, which ensures the stability of the material conveying process from the first cylinder to the hopper and avoids material leakage at the connection. The hopper and the receiving cylinder are detachably connected, which greatly improves the convenience of operation after material collection. When the material in the receiving cylinder reaches a certain amount, the operator can easily remove the receiving cylinder from the hopper to transfer or process the material, and then reinstall it in its original position to continue material collection. This reduces the operation steps and time costs, and facilitates the cleaning and maintenance of the receiving cylinder.

[0015] The outer diameter of the bushing is smaller than the outer diameter of the lead screw. An annular plate is fixedly provided on the side of the bushing near the nut. The outer wall surface of the sealing plate near the nut abuts against the annular plate, and the outer wall surface of the other side of the sealing plate abuts against the inner wall surface of the annular notch.

[0016] By adopting the above scheme, the sealing plate is limited, and the material is effectively prevented from leaking from the gap between the screw and the first cylinder during the conveying process.

[0017] The cross-section of the material receiving plate is arc-shaped.

[0018] In the above solution, the curved cross-section of the material receiving plate better matches the shape of the lead screw and helical blades, allowing for smoother material reception during the material receiving process and reducing material retention and accumulation on the plate. Furthermore, the curved structure increases the contact area with the material compared to a planar structure, improving the stability and efficiency of material receiving and ensuring that the material is uniformly and continuously conveyed to the hopper.

[0019] The above solution has the following advantages:

[0020] 1. Because the handwheel-type feeder of this utility model has a feeding plate and spiral blades, the drive mechanism drives the screw and feeding plate to extend into the discharge cylinder, and at the same time drives the screw to rotate. The feeding plate can pick up the material, and the spiral blades realize the material conveying. The operation is more labor-saving and convenient. The cooperation of the bushing, sealing plate and nut enhances the sealing performance of the feeder and limits the sealing plate, reducing the spillage and dust of material during the feeding process. This avoids material waste and maintains the cleanliness of the production environment. The hopper connected to the bottom of the first cylinder can collect the conveyed material in time.

[0021] 2. The drive mechanism includes a threaded rod and a threaded sleeve. A handle is provided at one end of the threaded rod. The use of the threaded rod, threaded sleeve, and handle for drive further improves the ease of operation. The operator can rotate the threaded rod by turning the handle, which in turn drives the lead screw through the threaded sleeve and connecting shaft. The transmission is smooth and labor-saving. Compared with the direct force application of the traditional pull-out structure, the strength is greatly reduced. This rotary drive mechanism makes the extension and retraction control of the lead screw more precise. It is convenient for the operator to accurately adjust the length of the lead screw extending into the discharge cylinder according to actual needs, thereby better controlling the amount of material taken out and improving the controllability of the material taking process.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In specific embodiment 1, such as Figures 1-5As shown, the handwheel-type feeder of this utility model includes a first cylinder 2 disposed on one side of the discharge cylinder 1. A lead screw 3 is disposed inside the first cylinder 2. A spiral blade 4 is fixedly disposed on the outer circumferential surface of the lead screw 3. An annular notch is provided on the outer circumferential surface of the lead screw 3 near the discharge cylinder 1. A bushing 5 is rotatably connected to the outer circumferential surface of the lead screw 3 corresponding to the annular notch. A sealing plate 6 is fixedly sleeved on the bushing 5. A feeding plate 7 is disposed below the lead screw 3. The sealing plate 6 is fixedly connected to the feeding plate 7. A nut 8 is disposed on the side of the lead screw 3 near the discharge cylinder 1. The nut 8 abuts against the outer wall surface of the sealing plate 6. The feeding plate 7 can pick up materials. The spiral blade 4 is used to realize the material conveying, making the operation more labor-saving and convenient. The cooperation of the bushing 5, the sealing plate 6 and the nut 8 enhances the sealing performance of the feeder and limits the sealing plate 6, reducing the spillage and dust of materials during the feeding process, thus avoiding material waste and maintaining the cleanliness of the production environment.

[0031] like Figure 1 As shown, a hopper 9 is connected to the bottom of the first cylinder 2, and the hopper 9 can collect and transport materials in a timely manner.

[0032] like Figure 3 As shown, a drive mechanism is provided on the side of the lead screw 3 away from the discharge cylinder 1. The drive mechanism includes a threaded rod 10 and a threaded sleeve 11. The threaded sleeve 11 is sleeved on the outside of the threaded rod 10, and the threaded sleeve 11 and the threaded rod 10 are in a rotating engagement. A connecting shaft 12 is provided between the threaded sleeve 11 and the lead screw 3. A handle 13 is provided on the end of the threaded rod 10 away from the connecting shaft 12. The use of the threaded rod 10, the threaded sleeve 11, and the handle 13 for driving further improves the convenience of operation. The operator can rotate the threaded rod 10 by turning the handle 13, which in turn drives the lead screw 3 through the threaded sleeve 11 and the connecting shaft 12. The transmission is smooth and labor-saving. Compared with the direct force application of the traditional pull-out structure, the strength is greatly reduced. This rotating drive engagement makes the extension and retraction control of the lead screw 3 more precise, allowing the operator to accurately adjust the length of the lead screw 3 extending into the discharge cylinder 1 according to actual needs, thereby better controlling the amount of material taken out and improving the controllability of the material taking process.

[0033] like Figure 3As shown, a second cylindrical body 14 is connected to the threaded sleeve 11. The inner wall of the second cylindrical body 14 abuts against the outer wall of the threaded sleeve 11. The end of the second cylindrical body 14 away from the handle 13 is fixedly connected to the end of the first cylindrical body 2 near the connecting shaft 12. The fixed connection between the second cylindrical body 14 and the first cylindrical body 2, and the abutment between the inner wall of the second cylindrical body 14 and the outer wall of the threaded sleeve 11, provides stable support and guidance for the threaded sleeve 11, enhances the structural stability of the drive mechanism, avoids shaking or deviation of the threaded sleeve 11 during rotation, ensures the smoothness of the transmission between the threaded rod 10 and the threaded sleeve 11, and thus ensures the stability of the extension and retraction of the lead screw 3 and the material conveying. In addition, the second cylindrical body 14 protects the threaded sleeve 11, reduces the interference of the external environment on the drive mechanism, and extends the service life of the feeder.

[0034] like Figure 4 As shown, the outer diameter of the bushing 5 is smaller than the outer diameter of the lead screw 3. An annular plate 16 is fixedly installed on the side of the bushing 5 near the nut 8. The outer wall surface of the sealing plate 6 near the nut 8 abuts against the annular plate 16, and the outer wall surface of the other side of the sealing plate 6 abuts against the inner wall surface of the annular notch, thereby limiting the sealing plate 6 and effectively preventing material from leaking from the gap between the lead screw 3 and the first cylinder 2 during the conveying process.

[0035] In a specific embodiment 2, such as Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the hopper 9 is fixedly connected to the first cylinder 2, and a receiving cylinder 15 is provided below the hopper 9. The hopper 9 and the receiving cylinder 15 are detachably connected. The fixed connection between the hopper 9 and the first cylinder 2 ensures the stability of the material conveying process from the first cylinder 2 to the hopper 9 and avoids material leakage at the connection point. The detachable connection between the hopper 9 and the receiving cylinder 15 greatly improves the convenience of operation after material collection. When the material in the receiving cylinder 15 reaches a certain amount, the operator can easily remove the receiving cylinder 15 from the hopper 9 to transfer or process the material, and then reinstall it in its original position to continue material collection. This reduces the number of operation steps and time costs, and facilitates the cleaning and maintenance of the receiving cylinder 15.

[0036] In a specific embodiment 3, such as Figure 5 As shown, the difference between this embodiment and embodiments 1 and 2 is that the cross-section of the material receiving plate 7 in this embodiment is arc-shaped. The arc-shaped cross-section of the material receiving plate 7 fits the shape of the lead screw 3 and the spiral blade 4 better, allowing for smoother material reception during the material receiving process and reducing material retention and accumulation on the material receiving plate 7. Moreover, the arc-shaped structure increases the contact area with the material compared to the planar structure, improving the stability and efficiency of material receiving and ensuring that the material can be uniformly and continuously conveyed to the hopper 9.

[0037] During operation, the operator turns handle 13 to drive the threaded rod 10 to rotate, thereby driving the threaded sleeve 11 to rotate and move along the length of the threaded rod 10. This causes the lead screw 3 and the spiral blade 4 to rotate synchronously and move horizontally. At this time, the material receiving plate 7 moves horizontally synchronously. When the material receiving plate 7 extends into the discharge cylinder 1, it can collect and remove the material in the discharge cylinder 1. The operator turns handle 13 in the opposite direction to drive the material receiving plate 7 to retract into the first cylinder 2. At this time, the spiral blade 4 rotates around the lead screw 3, which can transfer the material into the hopper 9 and finally fall into the receiving cylinder 15 for collection.

[0038] In the description of this utility model, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

For example, they can refer to mechanical or electrical connections, or internal connections between two components, and can be direct connections or indirect connections through an intermediate medium. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0039] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation. For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all implementation methods here, and any obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
