[0047] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0048] In related technologies, when loading ternary cathode material precursors and materials such as lithium hydroxide, the ton bags are made of two layers of bags. Ternary cathode material precursors and lithium hydroxide are prone to absorbing moisture, deteriorating, and electrostatic agglomeration.

[0049] Therefore, the feeding device requires a high degree of sealing during the feeding process. Nanoscale dust is generated during the feeding process of the ton bag, and inhalation of this dust by operators can harm their health. Materials such as lithium hydroxide are highly corrosive, and contact with them can cause burns to operators. Operators cut and re-bag the ton bags through the glove box of the feeding device. However, during the feeding process, material leakage generates nanoscale dust, which escapes through various connections in the feeding device, resulting in poor sealing and consequently affecting the environment and the health of operators.

[0050] In view of this, the ton bag feeding device provided in this application sequentially arranges the ton bag, the second sealing element, the first sealing element, and the discharge pipe on a support frame. During the ton bag feeding process (cutting and attaching the inner bag), the first and second pressing plates of the first sealing element approach each other, and the first and second pressing plates are used to squeeze and seal the ton bag, preventing the material from moving downwards, preventing dust generation, improving the sealing performance of the ton bag feeding device during the feeding process, and preventing environmental pollution and affecting the health of operators. The sealing plate of the second sealing element and the discharge pipe jointly squeeze and seal the ton bag, allowing the material to flow from inside the ton bag to the discharge pipe, preventing it from escaping from the connection between the ton bag and the discharge port, further improving the sealing performance of the ton bag feeding device during the feeding process, preventing environmental pollution and affecting the health of operators.

[0051] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0052] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0053] Reference Figure 1 As shown, this application embodiment provides a ton bag feeding device 1, which mainly transfers the material inside the ton bag 60 to a downstream processing system or equipment. The ton bag feeding device 1 ensures that the material can be discharged from the ton bag 60 relatively quickly, improving production efficiency. Furthermore, the ton bag feeding device 1 reduces reliance on manual operation and lowers labor intensity.

[0054] The ton bag 60 is equipped with an outer bag and an inner bag. The outer bag is made of polyethylene woven bag to enhance the strength of the ton bag, and the inner bag is made of aluminum foil bag to prevent damage to the material. The ton bag 60 of this application adopts the form of sealing the inner bag when feeding. This can prevent the material from flowing too fast when the bag is cut open, which would cause pressure on the hands and inconvenience in operation.

[0055] The ton bag feeding device 1 includes a support frame 10, a discharge pipe 20, a first sealing element 30, and a second sealing element 40. The support frame 10 supports the various structural components of the ton bag feeding device 1. The discharge pipe 20, the first sealing element 30, and the second sealing element 40 are mounted on the support frame 10 to ensure the stability of the structure during feeding and prevent tipping or displacement.

[0056] Because the material inside the ton bag 60 is relatively heavy, the support frame 10 can be used to support the ton bag 60. The ton bag 60 is placed on the upper part of the support frame 10, and the material inside the ton bag 60 will move downwards under the action of gravity.

[0057] For example, the support frame 10 can be welded from steel pipes. Using steel pipes for the support frame 10 can ensure its strength and reduces the difficulty of processing and design.

[0058] The support frame 10 is equipped with a protective cover 110, which can be used to cover the discharge pipe 20 or other components. The protective cover 110 is used to prevent dust from flying out during the feeding process, prevents operators from direct contact during operation, and also keeps the environment clean.

[0059] The protective cover 110 has an opening at its top for the ton bag 60 to pass through. An operating window 120 is located on the side of the protective cover 110, opposite to the discharge pipe 20. The operator uses the operating window 120 to attach the inner bag opening of the ton bag 60 to the inlet end of the discharge pipe 20.

[0060] In some embodiments, the support frame 10 can be height-adjusted to match the height of the operator with that of the operating window 120, allowing for comfortable operation in an ergonomic posture.

[0061] The discharge pipe 20 can be configured as a hollow pipe of a certain length. The inlet end of the discharge pipe 20 is connected to the outlet 610 of the ton bag 60. The discharge pipe 20 can move the material in the ton bag 60 to downstream equipment or containers under the action of gravity.

[0062] The outer surface of the feed end of the discharge pipe 20 is used to fit the ton bag 60 so that the feed end of the discharge pipe 20 is connected to the discharge port 610 of the ton bag 60.

[0063] The first seal 30 ensures the sealing of the ton bag 60 when the discharge pipe 20 is installed and before material feeding. The first seal 30 is positioned above the second seal 40. The first seal 30 includes a cooperating first clamping plate 310 and a second clamping plate 320. By bringing the first clamping plate 310 and the second clamping plate 320 close to each other, the first clamping plate 310 and the second clamping plate 320 are used to compress and seal the ton bag 60, preventing material from moving downwards.

[0064] When the operator places the inner bag opening of the ton bag 60 onto the inlet end of the discharge pipe 20, the first sealing element 30 ensures the airtightness of the ton bag 60, preventing the material from moving downwards and preventing dust generated by the ton bag feeding device 1 from harming the operator's health. Because the first pressing plate 310 and the second pressing plate 320 are spaced apart, the ton bag 60 can unfold without compression, allowing the material to flow out from inside the ton bag 60 for feeding.

[0065] In some embodiments, the first pressing plate 310 is provided with a pressing groove, the opening of which faces the second pressing plate 320. The second pressing plate 320 is provided with a protrusion that can be close to or away from the pressing groove. The protrusion cooperates with the pressing groove to compress and seal the ton bag 60.

[0066] When the first clamping plate 310 and the second clamping plate 320 approach each other, the protrusion is located in the clamping groove, and part or all of the protrusion can abut against the inner wall of the clamping groove. When the protrusion is fully or partially embedded in the clamping groove, the contact area between the two increases, the area of ​​the ton bag 60 located in the protrusion and the clamping groove increases, the sealing performance of the ton bag 60 is improved, and dust is prevented from being generated from the opening of the ton bag 60.

[0067] The second seal 40 is disposed on the support frame 10 and located above the feed end of the discharge pipe 20. The second seal 40 includes a sealing plate 410, which can be close to or away from the feed end of the discharge pipe 20. When the inner bag sleeve of the ton bag 60 is disposed outside the feed end of the discharge pipe 20, the sealing plate 410 and the discharge pipe 20 work together to compress and seal the ton bag 60. The second seal 40 provides a seal between the discharge port 610 of the ton bag 60 and the discharge pipe 20. Since the material inside the ton bag 60 is prone to generating dust, the first seal 30 prevents the material from being exposed to the air and causing harm to the health of the operators.

[0068] For example, the sealing plate 410 can be configured as an annular plate that can be pressed against the inlet end of the discharge pipe 20. This can reduce the processing difficulty of the sealing plate 410. The sealing plate 410 can also be configured as a pressure ring with a "U" shaped cross-section. By placing the pressure ring close to the discharge pipe 20 and fastening it to the inlet end of the discharge pipe 20, the sealing performance of the first sealing element 30 can be improved.

[0069] In some embodiments, a U-shaped sealing ring is provided at the inlet end of the discharge pipe 20. The U-shaped sealing ring is fixed to the inlet end of the discharge pipe 20 by its own elasticity. When the sealing plate 410 presses against the inlet end of the discharge pipe 20, the U-shaped sealing ring undergoes elastic deformation and tends to return to its original state, making the discharge pipe 20 and the ton bag 60 in close contact, which can improve the sealing performance of the second sealing element 40.

[0070] The ton bag feeding device 1 provided in this application arranges the ton bag 60, the second sealing element 40, the first sealing element 30, and the discharge pipe 20 sequentially on the support frame 10. During the ton bag feeding process (cutting and attaching the inner bag), the first pressing plate 310 and the second pressing plate 320 of the first sealing element 30 approach each other, and the first pressing plate 310 and the second pressing plate 320 are used to squeeze and seal the ton bag 60, preventing the material from moving downwards, preventing dust generation, improving the sealing performance of the ton bag feeding device 1 during the feeding process, and preventing environmental pollution and affecting the health of operators. When the material in the ton bag 60 moves downwards, the sealing plate 410 of the second sealing element 40 and the discharge pipe 20 work together to squeeze and seal the ton bag 60, causing the material to flow out from the ton bag 60 to the discharge pipe 20, preventing it from escaping from the connection between the ton bag 60 and the discharge port 610, further improving the sealing performance of the ton bag feeding device 1 during the feeding process, preventing environmental pollution and affecting the health of operators.

[0071] The first seal 30 and the second seal 40 will be described in detail below.

[0072] Reference Figure 2As shown, in some embodiments, the first pressing plate 310 and the second pressing plate 320 are arranged opposite each other. That is, the first pressing plate 310 is located opposite the second pressing plate 320, and they can cooperate to perform a pressing operation. The arrangement of the first pressing plate 310 and the second pressing plate 320 helps to maintain the stability of the first sealing member 30 when squeezing and sealing the ton bag 60, and prevents the ton bag feeding device 1 from tilting or deforming due to uneven force.

[0073] The first pressing plate 310 is movably disposed on the support frame 10 in a direction that approaches or moves away from the second pressing plate 320, and the second pressing plate 320 is movably disposed on the support frame 10 in a direction that approaches or moves away from the first pressing plate 310, so as to compress and seal the ton bag 60. The spacing between the first pressing plate 310 and the second pressing plate 320 can be adjusted by moving them closer or further apart to accommodate ton bags 60 of different sizes, thereby improving the versatility of the ton bag feeding device 1.

[0074] For example, the support frame 10 can be equipped with gears, and the first pressing plate 310 can be equipped with a rack. The gears and racks work together to move the first pressing plate 310. The gears and racks work together to achieve smoother movement, which improves the response speed of the ton bag feeding device 1 and thus improves the efficiency of the feeding operation.

[0075] For example, the support frame 10 can be equipped with gears, and the second pressing plate 320 can be equipped with a rack. The gears and racks work together to move the second pressing plate 320. The gears and racks work together to achieve fast and smooth movement, which improves the response speed of the ton bag feeding device 1, thereby improving the efficiency of the feeding operation.

[0076] The first sealing element 30 includes a first driving element 330 and a second driving element 340. The first driving element 330 and the second driving element 340 respectively drive the first pressing plate 310 and the second pressing plate 320 to move. The first driving element 330 and the second driving element 340 can respectively realize automated control of the first pressing plate 310 and the second pressing plate 320, making the movement of the first pressing plate 310 and the second pressing plate 320 faster and more accurate, improving the response speed of the ton bag feeding device 1, and thus improving the efficiency of the ton bag 60 feeding operation.

[0077] The first driving component 330 is disposed on the support frame 10 to fix the first driving component 330. The driving end of the first driving component 330 is used to drive the first pressing plate 310 to move, thereby realizing the control of the closing and opening of the ton bag 60.

[0078] Similarly, the second driving component 340 is disposed on the support frame 10 to fix the second driving component 340. The driving end of the second driving component 340 is used to drive the second pressing plate 320 to move, thereby realizing the control of the closing and opening of the ton bag 60.

[0079] The first driving member 330 and the second driving member 340 can precisely control the moving distance and speed of the first pressing plate 310 and the second pressing plate 320, thereby achieving control over the closing and opening of the ton bag 60. The first driving member 330 and the second driving member 340 can control the first pressing plate 310 and the second pressing plate 320 to move in a direction perpendicular to the axial direction of the discharge pipe 20.

[0080] For example, the first drive component 330 and the second drive component 340 can be configured as cylinders, connected to the first clamping plate 310 or the second clamping plate 320 via an output rod. Cylinders have the advantages of simple structure and easy maintenance, facilitating the maintenance or replacement of the first drive component 330 and the second drive component 340.

[0081] The first seal 30 also includes a control valve, which enables unified control of the first drive element 330 and the second drive element 340. The control valve can adjust the flow rate and pressure of the fluid as needed, thereby achieving precise control of the speed and force of the first drive element 330 and the second drive element 340.

[0082] The inlet of the control valve is at least connected to an air source. The first outlet of the control valve is connected to the first actuator 330, and the second outlet is connected to the second actuator 340. By connecting the first actuator 330 and the second actuator 340 through the control valve, the first actuator 330 and the second actuator 340 can be operated simultaneously, improving the accuracy of their synchronization. The control valve can simultaneously control the movement of the first actuator 330 and the second actuator 340, simplifying the control system and reducing the cost of the first seal 30.

[0083] In the second seal 40, the sealing plate 410 extends along the first direction. In other words, the sealing plate 410 extends circumferentially along the feed end of the discharge pipe 20 to form a sealing ring. This ensures that the sealing plate 410 can press against the feed end of the discharge pipe 20, making the discharge pipe 20 and the ton bag 60 in close contact, thereby improving the sealing performance of the first seal 30.

[0084] The second sealing element 40 includes multiple fourth driving elements 420, which can drive the sealing plate 410 to move axially along the discharge pipe 20. The multiple fourth driving elements 420 are arranged sequentially at intervals along the first direction. The driving end of the fourth driving element 420 is connected to the sealing plate 410, so that when the sealing plate 410 presses against the feed end of the discharge pipe 20, the force is uniform and the sealing performance is uniform, preventing dust from occurring during feeding.

[0085] For example, the number of fourth drive components 420 can be set to two, and the fourth drive component 420 can be set as a cylinder, which is connected to the sealing plate 410 through an output rod. Cylinders have the advantages of simple structure and easy maintenance, which facilitates the maintenance or replacement of the fourth drive component 420.

[0086] In some embodiments, the fourth driving member 420 is fixedly disposed on the outer surface of the discharge pipe 20. The fourth driving member 420 is closer to the inlet end of the discharge pipe 20, reducing the distance between the fourth driving member 420 and the sealing plate 410, allowing the sealing plate 410 to respond faster and press the inlet end of the discharge pipe 20 more quickly, thus improving feeding efficiency. Furthermore, by fixing the fourth driving member 420 to the outer surface of the discharge pipe 20, the space of the ton bag feeding device 1 can be fully utilized, helping to avoid a chaotic layout of the ton bag feeding device 1.

[0087] Reference Figure 3 As shown, the ton bag feeding device 1 also includes a pushing component 50, which allows the material to move downwards more smoothly during feeding and prevents the material from bridging inside the ton bag 60. The pushing component 50 is mounted on the support frame 10 to ensure stability during operation.

[0088] The pushing assembly 50 includes a movable pushing component 510, located on the side of the first seal 30 away from the discharge pipe 20. The pushing component 510 can be used to push the ton bag 60. The position and force of the pushing component 510 can be adjusted according to the amount of material in the ton bag 60 and the size of the ton bag 60, thereby achieving precise pushing. Through automated pushing, the pushing assembly 50 can improve the feeding efficiency of the ton bag feeding device 1.

[0089] There are multiple pusher components 510. Multiple pusher components 510 can simultaneously push the ton bag 60 inward, thereby accelerating the feeding speed. Therefore, the pusher assembly 50 also includes multiple third drive components 520 for driving the pusher components 510 to move.

[0090] The third drive unit 520 is disposed on the support frame 10, and the drive end of each third drive unit 520 is used to drive a pusher 510 to move. By controlling the output of the third drive unit 520, the moving speed and position of the pusher 510 can be controlled according to the amount of material in the ton bag 60.

[0091] The following describes the operation of the ton bag feeding device 1.

[0092] First, the ton bag 60 is transferred to the support frame 10 of the ton bag feeding device 1 using a forklift or overhead crane. The operation window 120 is opened, and the outer bag discharge port 610 of the ton bag 60 is rolled up through the operation window 120.

[0093] Then, the discharge port 610 of the inner bag of the ton bag 60 is turned downwards. The first driving member 330 and the second driving member 340 drive the sealing plate 410, the first pressing plate 310 and the second pressing plate 320 to move closer to each other. The protrusion of the second pressing plate 320 presses the inner bag of the ton bag 60 into the pressing groove of the first pressing plate 310, thereby sealing the inner bag of the ton bag 60 and preventing the material from moving downwards.

[0094] Next, the operator cuts open the opening of the inner bag of the ton bag 60 and places it over the inlet port of the discharge pipe 20. Multiple fourth drive components 420 drive the sealing plate 410 and the inlet port of the discharge pipe 20 to squeeze and seal the inner bag of the ton bag 60 together.

[0095] Subsequently, the operation window 120 is closed to seal the ton bag feeding device 1. The first drive component 330 and the second drive component 340 drive the sealing plate 410, the first pressing plate 310, and the second pressing plate 320 to move away from each other. The material inside the ton bag 60 moves downwards under the influence of gravity.

[0096] Finally, the third drive component 520 drives the pusher component 510 to move, which pushes the ton bag 60 to prevent material bridging inside the ton bag 60, thus accelerating the downward movement of the material. After the material in the ton bag 60 is completely fed, multiple fourth drive components 420 drive the sealing plate 410 to rise, removing the ton bag 60 and completing the ton bag feeding process.
