Description

Technical Field

[0001] This utility model relates to the field of sagger loading technology, specifically to a sealed loading system. Background Technology

[0002] Currently, in the production of powder materials such as positive and negative electrode materials for lithium-ion batteries, the materials to be sintered must first be loaded into saggers before being sintered at high temperatures in a kiln. To ensure the consistency and quality of the sintered material, there are requirements for the loading speed and conveying of the material into the saggers. Based on this, a production line has been applied to the field of sagger loading technology. A production line, also known as an "assembly line," is a production method in industry. It is a streamlined batch production route that processes materials from their initial state through a series of production processes, including processing, transportation, assembly, and inspection, to achieve the desired product. By utilizing each unit to focus on a specific task, the goal of improving work efficiency is achieved.

[0071] Example

[0072] like Figure 1-8This embodiment provides a sealed loading system suitable for feeding lithium battery material fillers into a crucible under sealed conditions. It also supports vacuum suction dust removal from the crucible supply device to prevent dust spillage and supports vacuum processing, facilitating rapid loading and preventing material oxidation and deterioration. The sealed loading system includes: a frame 10; a hopper device mounted on the frame 10; a loading mechanism at the outlet of the hopper device for storing and supplying materials to the loading mechanism; a crucible supply device mounted on the frame 10; the crucible supply device is connected to the loading mechanism and has a sealing door 21; a vacuum tube 16 located on the crucible supply device for evacuating the device; and a vacuum dust collection device located at the bottom of the crucible supply device for negative pressure suction of dust-laden air within the device, filtering and collecting the dust. The sealed loading system operates as follows: the hopper stores materials and supplies them to the loading mechanism, which then loads the saggers conveyed by the sagger supply device. Since the sagger supply device can be sealed by the sealing door 21, the feeding and loading processes can be performed in a closed environment, preventing dust escape and air pollution. Furthermore, a vacuum dust collection device can be activated promptly to extract and filter air from the sagger supply device; the filtered dust can be collected and reused. The negative pressure environment effectively prevents material oxidation and deterioration; it also facilitates the smooth and rapid output of materials by the loading mechanism for sagger loading. Simultaneously, the vacuum tube 16's vacuuming action allows the sagger supply device to quickly switch to a negative pressure environment, increasing the sagger conveying and loading speeds. Sagger supply and loading are guaranteed, and their cycles are effectively coordinated. Combined with vacuuming and negative pressure dust collection, this significantly improves the production efficiency of sagger loading.

[0073] like Figure 1-3 In one embodiment shown, the silo device includes a weighing silo 5 mounted on a frame 10. A ring plate 7 is provided on the frame 10 to support the weighing silo 5. The weighing silo 5 includes a weighing silo 5 body and multiple weighing sensors 6 arranged around the outer wall of the weighing silo 5 body. The bottom of the weighing silo 5 body passes through the ring plate 7, which can be flexibly positioned at the center of the weighing silo 5 body. The multiple weighing sensors 6 support the weighing silo 5 body on the ring plate 7 and are used to weigh the weighing silo 5 body and the material inside it. The weight of the material is obtained by subtracting the weight of the weighing silo 5 body itself during weighing. The weighing method using multiple weighing sensors 6 is called multi-point weighing. Processing the signals transmitted by each weighing sensor 6 allows for the calculation of an accurate weighing weight. This technology is prior art, and such equipment can be purchased directly. However, it is important to ensure the matching of the weighing range with the weighing capacity.

[0074] like Figure 4In one embodiment shown, the weighing hopper 5 body includes: a first conical shell 26 and a first top cover 51 located at the large end of the first conical shell 26. The small end of the first conical shell 26 is a discharge port, which is connected to a first transverse conveyor 11 via a discharge valve. The first top cover 51 is provided with a feed port. To prevent material agglomeration and improve the uniformity of the material, a first stirring mechanism 52 is disposed on the first top cover 51. The first stirring unit of the first stirring mechanism 52 extends into the first conical shell 26 to stir the material. The first stirring unit includes: a first drive shaft 521 and a first inclined rod 522 disposed on the first drive shaft 521. The rod body of the first inclined rod 522 is engaged with the inner wall of the first conical shell 26, and the first inclined rod 522 is used to stir the material. In addition, a first motor is disposed on the first top cover 51, and the first motor is connected to the first drive shaft 521 to drive the first drive shaft 521 to rotate the first inclined rod 522 to stir the material. Preferably, the first mixing unit includes an auger 524; the auger 524 is mounted on the first drive shaft 521 and cooperates with the discharge port, the auger 524 is used to mix materials and push materials out of the discharge port. Alternatively, the first mixing unit may include a mixing plate 523, the mixing plate 523 is located between the first drive shaft 521 and the first inclined rod 522, the mixing plate 523 is used to improve the degree of mixing, and the efficiency of material mixing is improved. Preferably, the mixing plate 523 is in an inclined state, the inclined surface of the mixing plate 523 makes pushing materials more effortless and efficient.

[0075] like Figure 1-3 In one embodiment shown, the silo device includes: a weighing buffer silo 2 disposed on the frame 10; the weighing buffer silo 2 is disposed on the frame 10 and connected to the feed inlet of the weighing silo 5, and the weighing buffer silo 2 is used to buffer materials for supplying the weighing silo 5.

[0076] Similarly, such as Figure 5 In one embodiment, the weighing buffer hopper 2 includes: a second conical shell 26, a second top cover 202 located at the large end of the second conical shell 26, and a second stirring mechanism 203 located on the second top cover 202; the small end of the second conical shell 26 is an outlet, and the second top cover 202 is an inlet; the second stirring unit of the second stirring mechanism 203 extends into the second conical shell 26. In one embodiment, the second stirring unit includes: a second drive shaft 2032 and a second inclined rod 2031 located on the second drive shaft 2032; the rod body of the second inclined rod 2031 engages with the inner wall of the second conical shell 26, and the second inclined rod 2031 is used to stir the material. Furthermore, a second motor 201 is located on the second top cover 202, and the second motor 201 is connected to the second drive shaft 2032 to drive the second drive shaft 2032 to rotate the second inclined rod 2031 and stir the material. The weighing buffer silo 2 enables continuous supply and buffering of materials, improving production efficiency; the optimized design of the second stirring mechanism 203 further improves the stirring effect and uniformity of materials.

[0077] like Figure 1-3 In one embodiment shown, the sealing and filling system includes a storage silo 1; the storage silo 1 is disposed on the frame 10 and used for storing materials. The storage silo 1 is located above the weighing buffer silo 2 and can supply materials to the weighing buffer silo 2. The design of the storage silo 1 realizes centralized storage and unified management of materials, which can improve the automation level and efficiency of the filler production process.

[0078] like Figure 1-3 In one embodiment shown, a first transverse conveyor 11 is arranged between the loading and displacing chamber 15 and the weighing silo 5. The loading and displacing chamber 15 and the weighing silo 5 are located at opposite ends of the first transverse conveyor 11, with the loading and displacing chamber 15 positioned below the weighing silo 5. The first end of the first transverse conveyor 11 is connected to the outlet of the weighing silo 5 via a first flexible connection mechanism 12, and the second end of the first transverse conveyor 11 is connected to the top of the loading and displacing chamber 15. The weighing silo 5 conveys materials to the loading and displacing chamber 15 via the first transverse conveyor 11, which facilitates a rational spatial arrangement of the two and enables efficient and stable material conveying. The first transverse conveyor 11 is a screw conveyor, particularly a tubular screw conveyor. The tubular screw conveyor uses a closed tubular shell with rotating helical blades inside. The material is propelled within the tube by the rotation of the helical blades. Whether the material is powdery, granular, or in small lumps, the tubular screw conveyor can achieve efficient conveying. The tubular screw conveyor adopts a fully enclosed structure, preventing material leakage into the external environment during conveying and also preventing external impurities from entering the conveyor. This sealed design not only reduces material waste and environmental pollution but also ensures the purity of the conveyed material. Similarly, a second transverse conveyor 3 is installed between the weighing buffer silo 2 and the weighing silo 5, with the weighing buffer silo 2 and the weighing silo 5 located at opposite ends of the second transverse conveyor 3. The first end of the second transverse conveyor 3 is connected to the outlet of the weighing buffer silo 2, and the second end of the second transverse conveyor 3 is connected to the inlet of the weighing silo 5 via a second flexible connection mechanism 4. The selection of the second transverse conveyor 3 is based on the first transverse conveyor 11.

[0079] like Figure 1 , 2In one embodiment shown in Figures 6-8, the sagger supply device includes: a sagger inlet replacement chamber 14 and a loading replacement chamber 15; the sagger inlet replacement chamber 14 is located on the frame 10, and a first conveying mechanism 17 is provided at the bottom of the sagger inlet replacement chamber 14; the loading replacement chamber 15 is located on the frame 10 and docks with the sagger inlet replacement chamber 14, and a second conveying mechanism 18 is provided at the bottom of the loading replacement chamber 15; the loading replacement chamber 15 is used to convert the sagger into a production environment suitable for the sagger inlet replacement chamber 14 before conveying saggers to the sagger inlet replacement chamber 14; wherein, both the sagger inlet replacement chamber 14 and the loading replacement chamber 15 are equipped with vacuum tubes 16. Both the first conveying mechanism 17 and the second conveying mechanism 18 are roller conveyors, which are mature products and readily available. A sealing door 21 is provided between the sagger inlet replacement chamber 14 and the loading replacement chamber 15, and the sealing door 21 is used to close the sagger inlet replacement chamber 14 and / or the loading replacement chamber 15. The sealing door 21 can connect the sagger inlet replacement chamber 14 and the loading replacement chamber 15, or it can be separated into an independent production environment unit. The specific implementation is as follows: The loading replacement chamber 15 has an environment conversion function. Before conveying saggers to the sagger inlet replacement chamber 14, it can be adjusted to a first production environment that is consistent with or basically consistent with the loading replacement chamber 15 (the parameters of the production environment, such as temperature, pressure, atmosphere, etc.). Then, the saggers are conveyed into the loading replacement chamber 15 via the first conveying mechanism 17. Subsequently, the sealing door 21 separates the sagger inlet replacement chamber 14 and the loading replacement chamber 15. The loading replacement chamber 15 performs production operations in the first production environment, and the sagger inlet replacement chamber 14 is converted to the second production environment and receives the next sagger. Repeating the above process can ensure the process continuity of saggers during the cross-functional area (i.e., the sagger inlet replacement chamber 14 is used for sagger inlet, and the loading replacement chamber 15 is used for loading) conveying process.

[0080] like Figure 3In one embodiment shown, the loading port of the loading mechanism is located in the loading and dispensing chamber 15. When the loading and dispensing chamber 15 is sealed, the loading mechanism drives the loading port to engage with the inlet of the sagger to be loaded in the loading and dispensing chamber 15 and load material. The loading mechanism is preferably a movable loading mechanism 9, which includes a support plate 92 located at the top of the loading and dispensing chamber 15 and a movable top cover 95 located within the loading and dispensing chamber 15. The support plate 92 serves as a support carrier and is opposite to the movable top cover 95. The movable top cover 95 can be driven to move downwards and close the inlet of the sagger to be loaded in the loading and dispensing chamber 15. A lifting unit 91 is provided on the support plate 92. The actuator of the lifting unit 91 passes through the support plate 92 and is connected to the movable top cover 95. The lifting unit 91 drives the movable top cover 95 to move up and down. The mobile loading mechanism 9 fills the saggers to be loaded in the loading replacement chamber 15 through a flexible loading channel 93. The first end of the flexible loading channel 93 is located on the support plate 92 and connected to the outlet of the weighing silo 5. The second end passes through the support plate 92 and connects to the loading port on the mobile top cover 95. The flexible loading channel 93 can be a corrugated pipe or a pipe made of flexible material. During filling, after the mobile top cover 95 moves down to engage with the inlet of the sagger to be loaded, the material output from the weighing silo 5 after weighing flows out (quantitatively) from the loading port of the mobile top cover 95 into the sagger to be loaded, thus completing the filling process.

[0081] like Figure 3 In one embodiment shown, the lifting unit 91 includes: a push rod 913 and a linear bearing passing through the top corner of the support plate 92; the first end of the push rod 913 is connected to the movable top cover 95; each top corner of the support plate 92 is correspondingly provided with a push rod 913; the linear bearing is sleeved on the outside of the push rod 913, with one linear bearing corresponding to one push rod 913, ensuring the smooth lifting and lowering of the push rod 913. The second ends of the two push rods 913 on the same side are connected to the same drive rod 911. A first linear actuator 912 is provided on the support plate 92, and the actuating end of the first linear actuator 912 is connected to the bottom of the drive rod 911. The first linear actuator 912 is used to push the drive rod 911 to drive the two push rods 913 to lift and lower synchronously. The first linear actuator 912 can be a cylinder or a hydraulic cylinder. The synchronous drive design of the lifting unit 91 ensures the smooth movement and precise docking of the movable top cover 95, improving the efficiency and accuracy of the filling.

[0082] like Figure 2 , 6In one embodiment shown, a sealing door 21 is provided between the sagger inlet replacement chamber 14 and the charging replacement chamber 15, and the sagger inlet replacement chamber 14 is used to seal the sagger inlet replacement chamber 14 and / or the charging replacement chamber 15; a transition chamber 25 is provided at the junction of the sagger inlet replacement chamber 14 and the charging replacement chamber 15; the first end of the transition chamber 25 is connected to the sagger inlet replacement chamber 14, and the second end is connected to the charging replacement chamber 15; wherein, the door panel 214 of the sealing door 21 between the sagger inlet replacement chamber 14 and the charging replacement chamber 15 is located inside the transition chamber 25. Preferably, the sealing door 21 includes: a first sealing door 24, a second sealing door 22, and a third sealing door 23. The first sealing door 24 is located at the inlet end of the sagger inlet replacement chamber 14 and is used to isolate the external environment. The second sealing door 22 is located between the inlet sagger replacement chamber 14 and the loading replacement chamber 15, achieving dynamic isolation between the two functional areas. The door panel 214 of the second sealing door 22 is located within the transition chamber 25. The second linear actuator is located outside and at the top of the transition chamber 25. A portion of the push rod 2112 passes through the top of the transition chamber 25 and connects to the actuating rod 2111 at the top of the outer side of the transition chamber 25. A mechanical seal is provided at the junction of the push rod 2112 and the top of the transition chamber 25. The third sealing door 23 is located at the outlet end of the loading replacement chamber 15, ensuring the output of the sagger after loading. The sagger supply device can separate the sagger inlet replacement chamber 14 and the loading replacement chamber 15 into independent production environment units through the cooperation of the first sealing door 24 and the second sealing door 22. After adjusting the production environment of the sagger inlet replacement chamber 14 to be consistent with that of the loading replacement chamber 15, the two are connected and the sagger is transported into the loading replacement chamber 15. Then, the second sealing door 22 separates the sagger inlet replacement chamber 14 and the loading replacement chamber 15 into independent production environment units. The sagger inlet replacement chamber 14 and the loading replacement chamber 15 each perform different processes. For example: when the second sealing door 22 and the third sealing door 23 are closed, the loading and replacement chamber 15 is in a vacuum environment; the sagger enters the sagger replacement chamber 14 through the first sealing door 24, the first sealing door 24 is closed, and the sagger replacement chamber 14 is evacuated to match the loading and replacement chamber 15; the second sealing door 22 is opened, the sagger is fed into the loading and replacement chamber 15, the second sealing door 22 is closed, and the sagger performs the loading process in the loading and replacement chamber 15; the first sealing door 24 is opened, the next sagger is fed into the sagger replacement chamber 14, the first sealing door 24 is closed, and a vacuum is evacuated; at the same time as the next sagger is fed into the sagger replacement chamber 14, the loading and replacement chamber 15 is completed and output from the third sealing door 23, the third sealing door 23 is closed, and a vacuum is evacuated; then, the second sealing door 22 is opened, and the next sagger enters the loading and replacement chamber 15 from the sagger replacement chamber 14, and so on, continuously completing the sagger input, sagger loading, and sagger output. Of course, the third sealing door 23 mentioned above can be eliminated. After the sagger is loaded, it returns to the sagger replacement chamber 14 and is then output. After that, the sagger replacement chamber 14 sends the next sagger into it. Of course, this design has a lower production efficiency than the above scheme.

[0083] like Figure 7 , 8 In one embodiment shown, the sealing door 21 includes: a frame 212; and a moving mechanism 213 disposed within the frame 212 and moving along a first direction. Figure 7 , 8 The first direction of movement is vertical, meaning the moving mechanism 213 moves in a lifting motion. The moving mechanism 213 can drive the door panel 214 to move synchronously. The door panel 214 is movably connected to the side of the moving mechanism 213 via multiple hinge rods 2133. The door panel 214 is opposite to the passage openings of the inlet sagger replacement chamber 14 and the loading replacement chamber 15. The limiting member 216 is located at the bottom of the frame 212 and is used to stop the door panel 214 from moving downward. The multiple hinge rods 2133 can be distributed on the upper and lower sides and the left and right sides of the door panel 214 to provide sufficient support. When the door panel 214 moves synchronously with the moving mechanism 213 along the first direction to the position of the limiting member 216, the limiting member 216 prevents the door panel 214 from moving forward. At this time, the door panel 214 stops in the first direction, the moving mechanism 213 continues to move along the first direction and drives the hinge rod 2133 to deflect. The first end of the hinge rod 2133 is driven by the moving mechanism 213 to move downward, and the second end of the hinge rod 2133 deflects and pushes the door panel 214 connected to the second end toward the passage opening, squeezing and sealing the passage opening.

[0084] like Figure 7 In one embodiment shown, the sealing door 21 includes a moving drive mechanism 211; the moving drive mechanism 211 is used to drive the moving mechanism 213 to move along a first direction. The moving drive mechanism 211 includes push rods 2112; the push rods 2112 are located on both sides of the moving mechanism 213 and are arranged in pairs, preferably symmetrically to ensure smooth and stable movement of the moving mechanism 213; the first end of each push rod 2112 is connected to the moving mechanism 213, and the second end passes through the top frame of the frame 212 and forms a sliding fit with the top frame; a linear bearing can be installed on the top frame to cooperate with the push rod 2112. Further, the second ends of the paired push rods 2112 are connected to the same actuating rod 2111, and a second linear actuator is provided on the top frame. The actuating end of the second linear actuator is connected to the bottom of the actuating rod 2111, and the second linear actuator is used to push the actuating rod 2111 to drive the paired push rods 2112 to move synchronously up and down. Among them, the second end of the pair of push rods 2112 is synchronized through the action rod 2111. By pushing the action rod 2111, the pair of push rods 2112 are driven to lift and lower, thereby driving the overall displacement of the moving mechanism 213 and the door panel 214 assembly.

[0085] like Figure 7In one embodiment shown, the moving mechanism 213 includes: a connecting plate 2131; a support plate 2134 disposed on the connecting plate 2131 and arranged along a first direction; the support plate 2134 comprises multiple pieces spaced apart, preferably evenly arranged; a first connecting rod 2132 passes through the support plate 2134; the first end of the hinge rod 2133 is rotatably engaged with the first connecting rod 2132, and the first connecting rod 2132 provides a fulcrum for rotation of the hinge rod 2133. Preferably, a sufficient number of support plates 2134 are provided to provide sufficient strength support for the first connecting rod 2132 to pass through and lift the door panel 214. Preferably, two first connecting rods 2132 are provided, corresponding to the upper and lower sides of the door panel 214.

[0086] like Figure 1 , 7 In one embodiment shown in Figure 8, the vacuum dust collection device adopts the following structure: a negative pressure fan is used to generate suction for the sagger supply device; a multi-stage filter is used to filter the dust-containing air drawn in by the suction; and a dust collection device collects the dust separated by the multi-stage filter. The vacuum dust collection device operates as follows: the strong suction generated by the negative pressure fan draws dust-containing air from the loading replacement chamber 15 and the sagger inlet replacement chamber 14 into the interior. After filtration by the multi-stage filter, the dust is separated and collected in the dust collection device. Specifically, vacuum dust collection devices can be provided at the bottom of both the loading replacement chamber 15 and the sagger inlet replacement chamber 14, and these devices are connected via a conical shell 26 and are attached to the small end of the conical shell 26.

[0087] The sealing and filling system works as follows: the storage silo 1 stores the material and conveys the material to the weighing buffer silo 2. After being buffered in the weighing buffer silo 2, the material is conveyed into the weighing silo 5 by the second transverse conveyor 3. The weighing silo weighs the material and discharges a fixed amount of material to the first conveying mechanism 17 through the valve at the lower end. The moving filling mechanism 9 loads the received fixed amount of material into the sagger below it. During the material conveying process described above, the sagger supply device delivers saggers to the mobile loading mechanism 9 for loading. Specifically, a sagger is placed into the sagger replacement chamber 14, the first sealing door 24 and the second sealing door 22 close the sagger replacement chamber 14, and the third sealing door 23 closes the loading replacement chamber 15. The sagger replacement chamber 14 and the loading replacement chamber 15 are evacuated. Once the vacuum environments of the two chambers are consistent or approximately consistent, the second sealing door 22 is opened, the sagger enters the sagger replacement chamber, and the second sealing door 22 is closed. The mobile loading mechanism 9 loads the saggers under vacuum. After loading is completed, the third sealing door 23 is opened, and the loaded sagger is transferred away through the third sealing door 23. Afterward, the loading replacement chamber 15 is evacuated again. While the mobile loading mechanism 9 is loading the saggers, the first sealing door 24 is opened, the vacuum is lost, and the next sagger is placed in. Then, the process is repeated, with the saggers entering the sagger replacement chamber, being loaded, and then transferred away. Simultaneously with the vacuuming process, the vacuum dust collection device is activated to draw in filtered dust from the air entering the sagger replacement chamber 14 and the loading replacement chamber 15. It also assists the vacuuming equipment on the vacuum tube 16 in quickly evacuating the sagger replacement chamber 14 and the loading replacement chamber 15, significantly improving production efficiency. Furthermore, the three production processes described above are synchronized and coordinated, greatly enhancing overall production efficiency. The processes of sagger supply, hopper supply, sagger loading, and sagger removal all operate under sealed conditions, limiting dust escape and preventing air pollution. Additionally, under vacuum, the material will not oxidize or deteriorate.
