Description

Technical Field

[0001] This invention belongs to the field of kiln facilities technology, and specifically relates to a sagger feeding device for a sagger conveying production line. Background Technology

[0002] The aforementioned sagger feeding device can also be called a sagger loading device or a sagger filling device. As those skilled in the art know, a sagger conveying device (also called a "sagger conveying mechanism," hereinafter the same) is usually provided between the furnace inlet and furnace outlet of a tunnel kiln used for calcining various electronic materials, lithium battery anode materials, etc. On the path of the sagger conveying device frame (also called a "sagger conveying mechanism frame," hereinafter the same), i.e., the channel, according to process requirements, there are not limited to, such as the sagger calcining material crushing mechanism, the sagger unloading mechanism, and the sagger cleaning mechanism, as listed below. The saggers containing calcined materials are transported from the furnace to the sagger calcination material crushing mechanism by the sagger conveyor. The crushed material is crushed (because many materials will form stubborn lumps after calcination). After crushing at the sagger calcination material crushing station, the sagger conveyor sends it to the sagger unloading mechanism to unload the material from the sagger (or the material can be sucked out directly by the suction pipe at the crushing station). Then, the sagger conveyor transports the unloaded saggers to the sagger cleaning station, where the aforementioned sagger cleaning mechanism cleans them. The sagger conveyor then transports the saggers to the feeding station, where the sagger feeding device feeds them. Finally, the sagger conveyor sends the material into the furnace from the furnace inlet, thus forming a cyclical, highly efficient production line process. Of course, if a non-damaged sagger inspection mechanism is added between the sagger cleaning mechanism station and the feeding station, then the saggers will enter the feeding station after passing through the damaged sagger inspection mechanism.

[0003] When the aforementioned crucibles are conveyed to the feeding station by the crucible conveying device of the crucible conveying production line, the crucible arrival signal collector, such as a photoelectric switch, installed on the frame of the crucible conveying device collects the signal and feeds it back to the electrical controller. The electrical controller then sends a signal to the crucible stop and release mechanism to raise it, stopping the crucible from moving forward, so that the crucibles temporarily stop at the feeding station to receive feeding from the feeding device.

[0004] As is known to those skilled in the art, some materials, such as graphene (often referred to as "graphite material") in the category of lithium-ion battery anode materials, are modified and removed by high-temperature calcination to change and remove the microstructure and impurities in graphite, thereby improving the conductivity, antioxidant properties, density and mechanical strength of the raw material, and so on. Currently, the aforementioned feeding stations all use a single-point center feeding method (i.e., feeding material directly into the center of the sagger) to load materials such as graphite powder into the sagger. Specifically, the material is loaded into the sagger in a quantitative manner (the material in each sagger is the same during the same batch of product production) through a loading port connected to the material cylinder. This loading method often results in a peak-shaped situation in the material in the sagger. The so-called peak-shaped situation means that the material in the middle or center of the sagger cavity is significantly higher than the upper surface of the sagger, forming a peak, while the surrounding area of ​​the sagger cavity is severely lacking in material, forming a trough. Therefore, the usual practice is to assign a worker to the aforementioned sagger loading mechanism station to scrape the material evenly using appropriate tools. However, the aforementioned disposal method has at least the following technical problems: First, it requires the assignment of additional workers to level the material in the sagger, thus wasting valuable labor resources; second, during the manual leveling process, slight carelessness can cause relatively expensive material to be scraped out of the sagger, resulting in waste; third, some materials, such as the aforementioned graphene material, are relatively loose due to their high air content. Therefore, during the manual leveling process, the dust generated not only severely damages the working environment but also poses a significant health risk to the workers. For example, workers who engage in this work for a long time may be at risk of developing pneumoconiosis. Another technical problem is that, since materials such as graphene (not limited to those mentioned above, which fall under the category of lithium-ion anode materials) are relatively porous, if the feeding device completes the feeding at the feeding station without proper compaction, material overflow from the sagger during its journey from entering to exiting the furnace will inevitably occur due to factors such as bumps or vibrations. This results in resource waste, and over time, as more material overflows from the sagger into the furnace cavity, it can lead to blockage of the furnace passages. Based on the foregoing, exploring measures to remedy these technical problems is of positive significance, and the technical solution described below arose in this context. Summary of the Invention

[0005] The objective of this invention is to provide a sagger feeding device for a sagger conveying production line that can simultaneously feed material into the sagger from multiple feeding points to make the material plane in the sagger more uniform, and can also compact the material in the sagger after feeding to prevent overflow into the furnace.

[0016] The technical advantages of the present invention are as follows: Because a sagger feeding mechanism that meets the requirements of multi-point synchronous feeding is used in the structural system of the sagger feeding device, the situation in the prior art where single-point feeding causes the material in the sagger to significantly exceed the sagger cavity opening due to redundancy, forming a peak, while the area around the sagger cavity far from the feeding point forms a valley due to severe material shortage, is avoided. This ensures that the material plane in the sagger is basically consistent with minimal differences. Furthermore, because a sagger material compaction sleeve is used, the material compaction is achieved... After the material is poured into the sagger, when the feeding valve plate actuation mechanism drives the feeding valve plate to close the lower outlet of the degassing screw mechanism, the feeding valve plate is simultaneously closed to the feeding valve plate mating cavity. When the sagger lifting mechanism at the feeding station is in the state of pushing the sagger upward, the feeding valve plate, in conjunction with the sagger material compaction sleeve, compacts the material in the sagger, preventing the material in the sagger from overflowing due to vibration and bumping in the furnace. This not only prevents waste of resources but also avoids clogging of the furnace passage over time. Attached Figure Description

The helical direction of the left thread 251 of the opening and closing screw at the left end of the opening and closing screw 25 of the crucible feed pipe fixing plate is opposite to the helical direction of the right thread 252 of the opening and closing screw at the right end of the opening and closing screw 25 of the crucible feed pipe fixing plate.

[0025] In this embodiment, a left feed tube sliding plate front slider position signal collector 1211 is provided on the upward-facing side of the left end of the aforementioned connecting column front beam left guide rail 121, and a right feed tube sliding plate front slider position signal collector 1221 is provided on the right guide rail 122 of the connecting column front beam, and on the left side of the aforementioned right feed tube sliding plate front slider 321 corresponding to the aforementioned left and right feed tube sliding plates 31, 32 of the feed tube in the closed state; the aforementioned feed tube fixing plate opening and closing drive Motor 21 is a motor with forward and reverse rotation functions; the aforementioned sagger feed pipe fixing plate opening and closing drive drive wheel 22 and sagger feed pipe fixing plate opening and closing screw drive wheel 23 are synchronous belt pulleys, and the aforementioned sagger feed pipe fixing plate opening and closing screw drive wheel transmission belt 24 is a synchronous belt; the aforementioned sagger feed pipe fixing plate opening and closing drive motor 21, sagger left feed pipe sliding plate front slider position signal acquisition device 1211 and sagger right feed pipe sliding plate front slider position signal acquisition device 1221 are electrically connected to the electrical controller in use.

[0026] When the feeder frame 61 at the aforementioned feeder station 6 detects (senses) that the crucible being conveyed to the left by a set of feeder station crucible conveyor rollers 62 has moved to the crucible position signal collector (not shown in the figure), and the photoelectric switch can collect the signal, the crucible position signal collector will feed the signal back to the electrical controller. The electrical controller will then issue a command to the feeder station crucible stop and release mechanism 66, thereby causing the feeder station crucible stop and release mechanism 66 to rise upward, preventing the crucible from continuing to move from right to left. Simultaneously, the electrical controller sends a signal to a pair of feeding station crucible clamping mechanisms 65, which clamp the front and rear outer walls of the crucible and immediately release them after clamping. This ensures that the crucible is positioned precisely in the center of the feeding station crucible conveying roller 62, preventing any tilting or horizontal movement. Therefore, the pair of feeding station crucible clamping mechanisms 65 described in this invention, whose function is to straighten the position of the crucible, can be called a "crucible alignment mechanism" or "crucible centering mechanism." The electrical controller also sends a signal to the aforementioned feeding station crucible lifting mechanism 64, causing it to raise the crucible so that its bottom is suspended above the feeding station crucible conveying roller 62 and approaches the bottom of the aforementioned crucible compaction sleeve 9.

[0027] After the aforementioned feeding station's sagger lifting mechanism 64 rises to the level set by the electrical controller (depending on the rotation speed and time of the sagger lifting drive motor 642 set by the PLC), the electrical controller simultaneously sends a signal or work command to the sagger feeding pipe fixing plate opening and closing drive motor 21. The sagger feeding pipe fixing plate opening and closing drive motor 21 operates clockwise, driving the sagger feeding pipe fixing plate opening and closing drive reduction gearbox 27. The final stage power output shaft 272 of the sagger feeding pipe fixing plate opening and closing drive reduction gearbox drives the sagger feeding pipe fixing plate opening and closing drive drive wheel 22. The sagger feeding pipe fixing plate opening and closing drive drive wheel 22 drives the sagger feeding pipe fixing plate opening and closing screw drive wheel 23 via the sagger feeding pipe fixing plate opening and closing screw drive wheel transmission belt 24. The sagger feeding pipe fixing plate opening and closing screw drive wheel 23 drives the sagger feeding pipe fixing plate opening and closing screw 25 to rotate, thus opening and closing the sagger feeding pipe fixing plate. The left thread 251 of the opening and closing screw at the left end of the screw 25 drives the left nut block 26b of the opening and closing screw, while the right thread 252 of the opening and closing screw at the right end of the screw 25 of the crucible feed pipe fixing plate drives the right nut block 26c of the opening and closing screw. Since the helical directions of the left and right threads 251 and 252 of the opening and closing screw are opposite, in the aforementioned process, the rotation of the screw 25 of the crucible feed pipe fixing plate causes the left and right nuts of the opening and closing screw to move. Blocks 26b and 26c move towards each other. As the left and right nut blocks 26b and 26c of the opening and closing screw move towards each other, they respectively drive the left and right feed pipe sliding plates 31 and 32 of the crucible to move towards each other. This continues until the signal from the aforementioned right feed pipe sliding plate front slider position acquisition device 1221 is detected by the device, indicating that the left and right feed pipe sliding plates 31 and 32 have moved towards each other and are now in a closed position. Simultaneously, the right feed pipe sliding plate front slider position acquisition device 1221 feeds back the collected signal to the electrical controller, which then sends a stop command to the crucible feed pipe fixing plate opening and closing drive motor 21. In this state, the closing of the left and right feed pipe sliding plates 31 and 32 causes the pair of left feed pipes 33 and the pair of right feed pipes 34 to also move towards each other accordingly. Figure 2 The shown approaching state is essentially a state in which the aforementioned saggers, located simultaneously below a pair of left feed pipes 33 and a pair of right feed pipes 34, are fed. In this state, feeding into the saggers is possible. During this feeding state, the feed opening / closing valve plate actuation mechanism 5, which will be described in detail below, drives the feed opening / closing valve plate 4, causing it to open and enter the position described below. Figure 5 As shown, the sagger is fed into the sagger by a pair of left sagger feed pipes 33 and a pair of right sagger feed pipes 34.

[0028] In this embodiment, the aforementioned slider position signal acquisition devices 1211 and 1221 in front of the left and right feed tube sliding plates of the sagger are micro switches, but limit switches, position proximity switches, reed switches or Hall effect sensors can also be used.

[0033] When the aforementioned left and right feed pipe sliding plates 31 and 32 of the crucible close together and the slider 321 of the right feed pipe sliding plate of the crucible touches the position signal acquisition device 1221 of the aforementioned right feed pipe sliding plate sliding plate, or when the position signal acquisition device 1221 of the right feed pipe sliding plate sliding plate of the crucible collects the position signal of the slider 321 of the crucible, the position signal acquisition device 1221 of the right feed pipe sliding plate sliding plate of the crucible feed pipe collects the signal and feeds the signal back to the electrical controller. The electrical controller then feeds the signal back to the aforementioned crucible feed pipe. The feed pipe fixing plate opening and closing drive motor 21 sends a stop signal and simultaneously sends a working command to the gas generating device, causing the aforementioned four feed opening and closing valve plate actuation mechanisms 5 to work simultaneously and synchronously. Specifically, the feed opening and closing valve plate actuation cylinder 52 works, causing the feed opening and closing valve plate actuation cylinder column 522 to move upward into the cylinder body. The feed opening and closing valve plate actuation cylinder column 522 drives the cylinder column length adjusting rod hinge joint 54 through the cylinder column length adjusting rod 53.

During this process, the degassing interfaces 816 and 825 of the upper and lower degassing screw cylinder cavities are in a state of negative pressure extraction of air from the material in the upper and lower degassing screw filter sleeve cavities 831 and 841. The air in the material cylinder 10 is introduced by a degassing actuator (not shown in the diagram).

[0034] After feeding the crucible is completed, the aforementioned feed opening and closing valve plate actuating cylinder 52 reverses its operation, causing the aforementioned feed opening and closing valve plate 4 to return to its original position according to the reverse process. Figure 4 The lower part of the degassing screw cylinder cavity 821 shown is in a closed state relative to the feeding hollow cavity 82413. This state means that the feeding valve plate 4 is in a closed state relative to the feeding valve plate mating cavity 91. At the same time, under the reverse operation of the crucible feeding pipe fixing plate opening and closing drive motor 21, the aforementioned crucible left and right feeding pipe sliding plates 31 and 32 are pushed apart and form a closed state. Figure 3 The state shown is such that the pair of left feed pipes 33 and the pair of right feed pipes 34 of the saggers are moved away from the area above the sagger cavity corresponding to the saggers until the slider 311 of the left feed pipe sliding plate is able to be acquired by the position signal acquisition device 1211 of the left feed pipe sliding plate. Only then will the position signal acquisition device 1211 of the left feed pipe sliding plate sliding plate feeder ...

Each modular dust collection hood 50 has a dust collection cavity suction outlet 503 at a corner of its top surface. In use, a suction pipe connected to the dust collection cavity suction outlet 503 is connected to a negative pressure suction device. The lower parts of each pair of adjacent modular dust collection hoods 50 are interconnected via dust collection hood splicing connecting ears 504. Dust generated during the feeding process into the crucibles via the aforementioned pair of left and right feeding pipes 33 and 34 enters the dust collection hood cavity 502 and is sucked out by the aforementioned suction pipe connected to the dust collection cavity suction outlet 503 using the negative pressure suction device.

When the crucible moves to a position where a signal can be acquired by the crucible position signal acquisition device (such as a photoelectric switch) mounted on the feeding station frame 61, as mentioned above, the acquisition device feeds back the signal to the electrical controller, causing the aforementioned feeding station crucible stop and release mechanism 66 to rise, preventing the crucible from moving further to the left. When the crucible touches the buffer damping block 6651, it also aligns precisely between the pair of feeding station crucible clamping mechanisms 65, which clamp and release the crucible as described above, ensuring the crucible's position meets the alignment requirements.

The sagger lifting drive motor mounting base 6421 is fixed on the sagger lifting base platform 6411 on the upper part of the sagger lifting base 641. The front end of the linkage worm gear 643 is connected to the front of the front worm gear box 646a. The worm gear box 646a is equipped with a worm gear drive, and the upper end of the front worm gear shaft 646e of the front worm gear box 646a is fixed to the lower side of the front center of the crock lifting frame fixing plate 646c. The rear end of the linkage worm 643 is equipped with the rear worm gear box 646b, and the upper end of the rear worm gear shaft 646f of the rear worm gear box 646b is fixed to the lower side of the rear center of the rear end of the crock lifting frame fixing plate 646c. The front worm gear box 646a is fixed to the upper side of the front end of the aforementioned crock lifting base platform 6411, and the rear worm gear box 646b corresponds to the front worm gear box 646a and is fixed to the upper side of the rear end of the crock lifting base platform 6411.The active synchronous pulley 644a is fixed to the aforementioned crucible lifting drive motor shaft 6422, and the driven synchronous pulley 644b is fixed to the middle of the linkage worm gear 643 along its length. One end of the synchronous belt 645 is sleeved on the active synchronous pulley 644a, and the other end is sleeved on the driven synchronous pulley 644b. The crucible lifting frame fixing plate 646c floats up and down above the crucible lifting base platform 6411.

During the feeding and weighing process of the crock, the pair of feeding station crock clamping mechanisms 65 do not contact the sides of the crock.

[0040] In this embodiment, the aforementioned sagger lifting drive motor 642 is a servo motor with forward and reverse rotation functions. When the sagger lifting drive motor 642 receives a working command from the electrical controller, it enters the working state and the sagger lifting drive motor shaft 6422 drives the active synchronous pulley 644a, which in turn drives the driven synchronous pulley 644b via the synchronous belt 645. The driven synchronous pulley 644b drives the linkage worm gear 643, which in turn drives the front worm gear box 646a and the rear worm gear box 646b. The worm wheels in the front and rear worm gear boxes 646a and 646b respectively drive the front and rear worm gear shafts 646e and 646f, which serve as worm gear shafts, to move upward. The upward displacement of the front and rear worm gear shafts 646e and 646f causes the sagger support fixing plate 646c, along with the sagger support 646d fixed on its upward-facing side, to move upward at the position corresponding to the conveyor roller space 621. The sagger support 646d (three in total) lifts the sagger upward, that is, pushes the empty sagger waiting to be filled upward, so that the bottom surface of the sagger leaves the sagger conveyor roller 62 at the feeding station and is in the receiving state. As mentioned above, when the feeding valve plate 4 is in the open state, and when a pair of sagger left feeding pipes 33 and a pair of sagger right feeding pipes 34 are simultaneously feeding into the sagger, the aforementioned stirring screw 40 is in the working state, and the spiral blades 401 drive the material downward. When the material level in the sagger reaches the weight set value of each pair of front and rear weighing sensors 648a and 648b, the sensors feed back signals to the electrical controller. The electrical controller then sends signals to the four feed valve plate actuation cylinders 52, causing them to operate and close the feed valve plate 4. Specifically, the feed valve plate 4 is in a closed state, sealing the discharge cavity 82413. Figure 1 and Figure 4 The diagram shows the closed state of the feed valve plate mating cavity 91. Simultaneously, under the command of the electrical controller, as described above by the applicant, the left and right feed pipe sliding plates 31 and 32 of the crucible are moved by the operation of the crucible feed pipe fixing plate opening and closing drive mechanism 2. Figure 3The open state is shown so that the left and right feed pipes 33 and 34 of each pair of saggers are removed from the area corresponding to the upper cavity of the sagger. When the sliding plates 31 and 32 of each pair of saggers are in the open state, the position of the front slider 311 of the left feed pipe is such that the signal can be collected by the position signal acquisition device 1211 of the left feed pipe sliding plate and the collected signal is sent to the electrical controller. The electrical controller issues a command to stop the sagger feed pipe fixing plate opening and closing drive motor 21 of the sagger feed pipe fixing plate opening and closing drive mechanism 2. At the same time, the electrical controller issues a command to the sagger lifting drive motor 642 to push the sagger upward again in the same manner as described above, so that the feed opening and closing valve plate 4, which is in the closed state, cooperates with the sagger material compaction sleeve 9 at the position corresponding to the feed opening and closing valve plate mating cavity 91 to compact the material in the sagger. After a set delay time, such as 1-3 seconds, the sagger lifting drive motor 642 reverses its operation, performing the opposite action process to place the sagger filled with material onto the sagger conveying roller 62 at the feeding station. At this time, the sagger stop and release mechanism 66 at the feeding station moves downward under the instruction of the electrical controller to open the sagger travel channel, allowing the sagger to carry the material into the furnace.

[0041] The applicant needs to clarify that, in this embodiment, the above description refers to the compaction action performed when the sagger is filled with material all at once, i.e., when the weight sensing value set by the pair of sagger material weighing sensors 648a and 648b is reached. However, under the guidance of the foregoing content of this invention, material can be introduced into the sagger in several stages, and the material in the sagger can be compacted. That is, the introduction of material into the sagger and the compaction of the sagger material can be alternated multiple times until the final material quantity value of the pair of sagger material weighing sensors 648a and 648b is reached. The sagger to be filled moves out of the pair of feeding station 6 and enters the furnace through the sagger stop and release mechanism 66. The next sagger to be filled then arrives and arrives above the sagger lifting mechanism 64 corresponding to the feeding station and simultaneously between the sagger clamping mechanism 65 corresponding to the feeding station, repeating the above process for feeding. Furthermore, based on professional knowledge, whether to fill the sagger with material all at once and then compact it, or to fill and compact the material in two or more processes until the sagger is full to the set weight, depends on the material or the requirements of the process.

[0044] As mentioned above, when the sagger position signal acquisition device, such as the photoelectric switch, located on the feeding station frame 61 at feeding station 6 (as mentioned twice above) acquires the position of the sagger moving from right to left, it indicates that the sagger has reached the position required by the process, that is, the sagger has reached the position above the aforementioned feeding station sagger lifting mechanism 64 and between the pair of feeding station sagger clamping mechanisms 65.
