Description

Technical Field

[0001] This utility model relates to the field of coal powder processing technology, specifically to an automatic coal powder packaging device. Background Technology

[0002] Powdered coal is a granular material made from coal through crushing, grinding, and other processing techniques. It is widely used in industrial boiler combustion, coal chemical raw materials, and metallurgical auxiliary fuel. Due to its small particle size and high fluidity, it easily generates dust during storage and transportation, which not only causes material loss but may also affect the operating environment and personnel health. Therefore, it is necessary to achieve standardized management through specific packaging methods.

[0003] Coal powder packaging is a key link between coal powder production and use. Its core purpose is to reduce dust, ensure material purity, and facilitate subsequent storage and transportation.

[0004] Currently, most coal powder packaging operations on the market are still mainly manual, with a low degree of automation and obvious technical defects: the feeding process relies on manual labor to move empty coal powder barrels to the filling position, the unloading process requires manual transfer of the packaged barrels, and the capping and sealing process requires manual alignment of the barrel caps. Each process is operated independently without a continuous automated flow mechanism, resulting in a fragmented overall operation process, high labor intensity, and low efficiency. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an automatic coal powder packaging device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic coal powder packaging device, comprising a main body, inside which are respectively arranged a feeding component, a transfer component, a powder loading component, a hanger, a top cover component, a sealing component, and a discharging component; the transfer component includes an electric turntable installed at the lower part of the main body, a photoelectric proximity switch installed on one side of the main body, and four ultrasonic sensors installed on the top of the hanger, and the output end of the electric turntable is connected to the turntable body, the top of the turntable body is respectively connected to a positioning plate and a sensing plate; the powder loading component includes a powder inlet opened at the top of the main body, a dustproof brush connected to the upper part of the main body, and a mounting plate. The equipment includes a lifting cylinder located below the main body, with a weighing device installed at its output end; the upper cover assembly includes an upper cover compartment connected to one side of the top of the main body, and two positioning cylinders installed on the other side of the main body and one on the top of the hanger, with a cover storage rack connected below the upper cover compartment; the upper cover compartment contains two upper cover cylinders and two cover clamping cylinders, with baffle plates connected to the output ends of both upper cover cylinders; the pressing assembly includes a top pressing cylinder installed below the main body, with a top pressing plate connected to its output end; the pressing assembly also includes a bottom pressing cylinder installed on the top of the main body, with a bottom pressing frame connected to its output end.

[0007] By adopting the above technical solutions, the electric turntable of the transfer component drives the coal powder bucket to move across workstations, replacing manual transfer; the dust brush of the powder loading component reduces dust during powder loading, and the weighing device combined with the lifting cylinder achieves accurate measurement and automatic reset; the positioning cylinder of the top cover component ensures the positioning accuracy of the bucket lid, and the lid clamping cylinder and the cover plate work together to separate a single lid and avoid multiple lids falling off accidentally; the top pressure plate and the lower pressure frame of the lid pressing component apply pressure in both directions to improve the tightness of the lid fastening. All components work together to greatly reduce manual intervention and solve the problem of low automation in traditional packaging.

[0008] Furthermore, the feeding assembly includes a feeding conveyor installed inside one side of the equipment body, and an electric slide is installed on the top of the feeding conveyor. The output end of the electric slide is connected to a feeding push plate, and a feeding bridge is connected to one side of the feeding conveyor. The unloading assembly includes an unloading cylinder installed on the top of the hanger and an unloading conveyor installed on the outer surface of the equipment body, and the output end of the unloading cylinder is connected to a unloading push plate.

[0009] By adopting the above technical solution, the feeding conveyor automatically transports empty barrels, and the electric slide table drives the feeding pusher plate to complete the transfer of the barrel from the conveyor to the turntable. The feeding bridge fills the gap to reduce the risk of the barrel falling. The unloading cylinder pushes the packaged barrel to the unloading conveyor through the unloading pusher plate, and the conveyor sends it out of the equipment, replacing manual handling and pushing, reducing labor intensity, and ensuring the stability of the feeding and unloading process, connecting the overall packaging process.

[0010] Furthermore, there are eight positioning plates and eight sensing plates, and the eight positioning plates and eight sensing plates are arranged in a circular array, with the eight positioning plates and eight sensing plates being staggered.

[0011] By adopting the above technical solution, the eight positioning plates have only one gap reserved to support seven coal powder barrels at the same time. The circular array distribution, combined with the rotation of the turntable, enables the synchronous circulation of multiple barrels and avoids the fragmentation of single-barrel operation. The positioning plates and sensing plates are staggered, which not only limits the barrels through the positioning plates, but also detects the turntable angle through the sensing plates and photoelectric proximity switches, ensuring that each barrel is accurately connected to different processes and improving the overall operation efficiency.

[0012] Furthermore, the photoelectric proximity switch corresponds to one of the sensing plates.

[0013] By adopting the above technical solution, when the turntable drives the induction plate to rotate, the photoelectric proximity switch senses the position of the corresponding induction plate and sends a real-time feedback signal to the control unit to determine whether the turntable has reached the preset stopping angle. This ensures that the coal powder bucket in the positioning plate can be accurately aligned with the powder loading, cover, pressure cover or unloading components each time it stops, reducing workstation docking deviation and avoiding process errors or equipment idling caused by misalignment.

[0014] Furthermore, the positioning plate has an "n" shaped cross-section, and both sides of the outer surface of the positioning plate are sloped.

[0015] By adopting the above technical solutions, the n-shaped structure can circumferentially limit the coal powder bucket, reducing the lateral displacement of the bucket during the transfer process; the sloping design on both sides can automatically calibrate the position of the bucket through the inclined guide when the feeding push plate pushes the bucket, so that the bucket can fall into the reference position of the positioning plate without manual adjustment, laying the foundation for the precise operation of subsequent processes such as filling powder and covering.

[0016] Furthermore, the longitudinal section of the cover plate is L-shaped.

[0017] By adopting the above technical solution, the L-shaped longitudinal section supports the stacked bucket lids through the horizontal section and achieves translation through the vertical section in cooperation with the top cover cylinder. This ensures that only a single bucket lid falls when the baffle plate is removed, and that it can accurately return to the bottom of the remaining bucket lids when reset, avoiding sealing errors caused by multiple lids falling at the same time and improving the reliability of the top cover process.

[0018] Furthermore, the top pressure plate corresponds to the position of the lower pressure frame.

[0019] By adopting the above technical solution, the top pressure plate and the lower pressure frame are aligned vertically. When the lid is pressed, the top pressure plate pushes the coal powder bucket upward under the drive of the top pressure cylinder, and the lower pressure frame presses the lid downward under the drive of the lower pressure cylinder. The bidirectional synchronous pressure makes the lid and the bucket body fit tightly together. Compared with unidirectional pressure, it is easier to eliminate the gap between the fit and reduce the problem of loose sealing, ensuring that the coal powder is not easily leaked or damp during storage and transportation.

[0020] Furthermore, a control cabinet is installed on one side of the top of the main body of the equipment, and the feeding conveyor, electric slide table, electric turntable, photoelectric proximity switch, lifting cylinder, weighing device, positioning cylinder, cover cylinder, cover clamping cylinder, top pressing cylinder, bottom pressing cylinder, unloading cylinder and unloading conveyor are all electrically connected to the control cabinet; a coal powder bucket is placed on the top of the feeding conveyor and the unloading conveyor, and a bucket lid is connected to the top of the coal powder bucket and the inside of the storage cover rack.

[0021] By adopting the above technical solution, the control cabinet, as the core control unit, receives feedback signals from each component and sends start / stop or action commands to each execution component to ensure the coordinated operation of processes such as feeding, transfer, and pulverizing. The preset placement positions of the pulverized coal bucket and lid directly connect to the material requirements of each process, forming a complete material flow closed loop from empty bucket feeding to lid replenishment, avoiding process interruptions caused by material shortages.

[0022] Furthermore, the transfer assembly also includes four damping springs connected to both sides inside the main body of the equipment, and one end of each of the four damping springs is connected to a roller frame. The four damping springs and roller frames are arranged in a circular array.

[0023] By adopting the above technical solution, when the barrel body deviates, the damping spring undergoes elastic deformation along the axial direction, which drives the roller frame to apply a reverse thrust to the barrel body, pushing the deviated barrel body back to the reference position, ensuring the stability of the barrel body during the revolution process, and avoiding the deviation from affecting subsequent processes.

[0024] Furthermore, both the feeding conveyor and the unloading conveyor are powered roller conveyors.

[0025] By adopting the above technical solutions, the powered roller conveyor can withstand greater barrel weight, avoiding barrel tilting, jamming, or conveying interruption due to insufficient load capacity. At the same time, the stability of the roller conveyor can reduce the shaking of the coal powder barrel during the conveying process. Especially for heavy barrels filled with coal powder, it can ensure smooth material feeding and further guarantee the reliability of the overall packaging process.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model, through the arrangement of a powder loading assembly, a top cover assembly, and a pressure cap assembly, addresses the issue of dust generation during the loading process. In the powder loading assembly, the dust brush fits snugly against the top of the pulverized coal bin, reducing material loss and environmental impact. The weighing device, driven by a lifting cylinder, fits snugly against the bottom of the pulverized coal bin. After zeroing the weight of the bin, it performs real-time measurement of the pulverized coal, minimizing uneven loading and ensuring consistent weight for each bin. The lifting cylinder drives the weighing device to lower and reset after loading, preventing interference with subsequent transport of the pulverized coal bin. In the top cover assembly, two positioning cylinders... The system enables precise positioning of the pulverized coal bucket, reducing alignment deviations when the lid falls. The clamping cylinder, in conjunction with the baffle plate, allows for single-lid separation of stacked lids, preventing sealing errors caused by multiple lids falling simultaneously. The top-lid cylinder drives the baffle plate to slide and reset, preparing for the next lid placement and improving automation. In the lid-pressing assembly, the bidirectional pressure design—with the top-pressing cylinder driving the top plate upwards and the bottom-pressing cylinder driving the bottom frame downwards—improves the tightness of the lid's fit with the pulverized coal bucket, reducing issues of insecure sealing and ensuring sealing quality. It facilitates automated filling and is easy to operate.

[0028] 2. This utility model, through the setting of the transfer components, uses an electric turntable to drive the turntable body to rotate slowly, causing the pulverized coal bucket to revolve between four core workstations, replacing the traditional manual transfer method and reducing human intervention. The photoelectric proximity switch, in conjunction with the sensing plate, can accurately determine the rotation angle of the turntable body, ensuring that the pulverized coal bucket accurately aligns with the filling, capping, pressing, and unloading components each time the turntable stops, reducing workstation docking deviations. Ultrasonic sensors can detect the presence of pulverized coal buckets at the four workstations, ensuring that the corresponding components only activate when a bucket is present or absent, avoiding energy waste and equipment damage caused by idling. The positioning plate determines the reference position of the pulverized coal bucket when the feeding pusher delivers the bucket, laying the foundation for precise operation in subsequent processes. Simultaneously, the design of eight positioning plates on the turntable body reserves space only between the pressing and unloading components and the feeding components for buckets without buckets; the other seven positioning plates can support the pulverized coal buckets, enabling continuous packaging operations and significantly improving overall production efficiency. It facilitates automatic transfer and continuous processing, improving efficiency.

[0029] 3. This utility model, through the setting of a feeding component and a discharging component, allows the feeding conveyor in the feeding component to automatically send empty coal powder buckets into the equipment, replacing manual handling; the electric slide table drives the feeding pusher plate to transfer the coal powder buckets from the conveyor to the top of the turntable body without manual assistance; the feeding bridge fills the gap between the feeding conveyor and the turntable body, reducing the risk of coal powder buckets falling during the transfer process and ensuring the stability of the feeding process; in the discharging component, the discharging cylinder can automatically push the sealed coal powder buckets to the discharging conveyor through the discharging pusher plate, and then the discharging conveyor sends the finished buckets out of the equipment, realizing the automatic transfer of the sealed buckets; the automation of the feeding and discharging links not only seamlessly connects the start and end of the entire sealing process, but also reduces the amount of manual labor, lowers labor costs, and further improves the continuity and efficiency of the overall operation.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The embodiments of this utility model will be described below based on its overall structure.

[0040] Example 1:

[0041] An automatic coal powder packaging device, such as Figures 1-7 As shown, the equipment includes a main body 1, and the main body 1 is equipped with a feeding assembly 2, a transfer assembly 5, a powder loading assembly 6, a hanger 7, a top cover assembly 8, a cover pressing assembly 9, and a discharging assembly 10.

[0042] Specifically, the feeding assembly 2 includes a feeding conveyor 201 installed inside one side of the equipment body 1, an electric slide table 202 installed on the top of the feeding conveyor 201, a feeding push plate 203 connected to the output end of the electric slide table 202, and a feeding bridge 204 connected to one side of the feeding conveyor 201.

[0043] Specifically, the transfer assembly 5 includes an electric turntable 501 installed inside the lower part of the equipment body 1, a photoelectric proximity switch 505 installed inside one side of the equipment body 1, and four ultrasonic sensors 508 installed on the top of the hanger 7. The photoelectric proximity switch 505 corresponds to one of the sensing plates 504. The output end of the electric turntable 501 is connected to the turntable body 502. The top of the turntable body 502 is connected to a positioning plate 503 and a sensing plate 504, respectively. The positioning plate 503 has an "n"-shaped cross-section, and both sides of the outer surface of the positioning plate 503 are sloped. The electric turntable 501 drives the turntable body 502 to rotate slowly, causing the pulverized coal bucket 3 inside the positioning plate 503 to revolve, realizing cross-station transfer. The slow rotation avoids generating large centrifugal forces that could cause the pulverized coal bucket 3 to shift. The eight positioning plates 503 on the top of the turntable body 502 are arranged in a staggered ring array. Except for the gap between the station of the capping unloading component 10 and the station of the loading component 2, which does not contain a pulverized coal bucket 3, the other seven positioning plates 503 all carry pulverized coal buckets 3, thereby achieving continuous transfer and providing support for subsequent continuous packaging. The positioning plates 503 and the induction... Each plate 504 is equipped with eight positioning plates 503 and eight sensing plates 504 arranged in a circular array. The eight positioning plates 503 and eight sensing plates 504 are staggered. The photoelectric proximity switch 505 cooperates with the eight sensing plates 504 on the turntable body 502 to detect the rotation angle of the turntable body 502 in real time, ensuring that the coal powder bucket 3 can accurately correspond with the coal powder loading component 6, the top cover component 8, the pressure cover component 9, and the unloading component 10 each time the turntable stops rotating. Meanwhile, the four ultrasonic sensors 508 on the top of the hanger 7 simultaneously detect the coal powder loading component 2 and the coal powder loading component 10. The sensor detects whether there is a coal powder hopper 3 at the four stations: Component 6, Top Cover Component 8, Covering Component 9, and Discharge Component 10. If there is no hopper at the station where Component 6, Top Cover Component 8, Covering Component 9, and Discharge Component 10 are located, the sensor will send a signal to the control cabinet 11. The control cabinet 11 will then control the corresponding components to temporarily stop starting to avoid energy waste and equipment damage caused by idling. If there is a hopper at the station where Discharge Component 2 is located before discharging, the control cabinet 11 will alarm and stop the machine. The operator needs to manually remove the hopper. If there is no hopper at the station where Discharge Component 2 is located, the discharging operation will proceed normally.

[0044] Specifically, the powder loading assembly 6 includes a powder inlet 601 located at the top of the main body 1, a dust brush 602 connected to the upper part of the main body 1, and a lifting cylinder 603 installed at the lower part of the main body 1. A weighing device 604 is installed at the output end of the lifting cylinder 603. The lifting cylinder 603 first extends upward, driving the weighing device 604 through the round hole at the bottom of the turntable body 502 until it is tightly fitted with the bottom of the coal powder bucket 3. The weighing device 604 then automatically resets to zero, removing the weight of the coal powder bucket 3, i.e., removing the gross weight, to ensure that subsequent measurement is only based on the weight of the coal powder. Afterwards, the external pneumatic conveyor and The coal powder inlet 601 is connected to transport coal powder into the coal powder bucket 3. During this process, the dust brush 602 is close to the coal powder bucket 3 to reduce dust in the main body 1 of the equipment when the coal powder falls, thereby reducing material loss and environmental impact. At the same time, the weighing device 604 monitors the weight change of the coal powder bucket 3 in real time. When the weight reaches the preset value, that is, the coal powder is filled in place, the weighing device 604 sends a signal to the control cabinet 11. The control cabinet 11 controls the pneumatic conveyor to stop feeding coal powder. Then the lifting cylinder 603 retracts downward, driving the weighing device 604 to move down and reset, so as to avoid the weighing device 604 from obstructing the subsequent revolution and transfer of the coal powder bucket 3.

[0045] Specifically, the cover assembly 8 includes a cover chamber 802 connected to one side of the top of the equipment body 1, and two positioning cylinders 801 installed inside the equipment body 1 on the other side and on one side of the top of the hanger 7. A cover storage rack 806 is connected to the lower part of the cover chamber 802. Two cover cylinders 803 and two cover clamping cylinders 805 are installed inside the cover chamber 802. The output ends of the two cover cylinders 803 are connected to baffle plates 804. The longitudinal section of the baffle plates 804 is "L" shaped. The two positioning cylinders 801 first extend towards the coal powder bucket 3 to push the coal powder bucket 3 to further calibrate its position and reduce the alignment deviation when the bucket cover 4 falls. Then the cover clamping cylinders 805 are activated. The cylinder 805 clamps the second bucket lid 4 from the bottom up inside the lid rack 806 to prevent the stacked bucket lids 4 from falling as a whole. Then, the lid cylinder 803 drives the baffle plate 804 to move horizontally, so that the baffle plate 804 moves away from the bottom of the bottom bucket lid 4. The bottom bucket lid 4 falls to the top of the coal powder bucket 3 under the influence of gravity. After the lid is installed, the lid cylinder 803 immediately drives it to move horizontally and reset, returning to the bottom of the remaining stacked bucket lids 4 for support. Finally, the lid clamping cylinder 805 releases the clamp on the second bucket lid 4, and the remaining bucket lids 4 fall one position under the action of gravity, preparing for the next lid installation. At the same time, the positioning cylinder 801 retracts and resets, ending the positioning of the coal powder bucket 3.

[0046] Specifically, the capping assembly 9 includes a top-pressure cylinder 901 installed inside the lower part of the equipment body 1, with a top-pressure plate 902 connected to the output end of the top-pressure cylinder 901. The capping assembly 9 also includes a bottom-pressure cylinder 903 installed on the top of the equipment body 1, with a bottom-pressure frame 904 connected to the output end of the bottom-pressure cylinder 903. The top-pressure plate 902 and the bottom-pressure frame 904 are positioned correspondingly. The top-pressure cylinder 901 extends upward, driving the top-pressure plate 902 to move upward and apply upward pressure to the bottom of the pulverized coal bucket 3. At the same time, the bottom-pressure cylinder 903 extends downward, driving the bottom-pressure frame 904 to move downward and apply downward pressure to the lid 4 on the top of the pulverized coal bucket 3. Through bidirectional synchronous pressure application, the lid 4 and the pulverized coal bucket 3 are tightly fastened, reducing the problem of insecure sealing and completing the capping sealing operation.

[0047] Specifically, the feeding assembly 10 includes a feeding cylinder 1001 installed on the top of the hanger 7 and a feeding conveyor 1003 installed on the outer surface of the equipment body 1. The output end of the feeding cylinder 1001 is connected to a feeding push plate 1002. The feeding cylinder 1001 drives the feeding push plate 1002 to move towards the coal powder bucket 3, pushing the sealed coal powder bucket 3 from the positioning plate 503 to the top of the feeding conveyor 1003. Finally, the control cabinet 11 controls the feeding conveyor 1003 to operate, sending the sealed coal powder bucket 3 out of the equipment body 1, completing the entire automatic coal powder sealing process.

[0048] See 1- Figure 7 In the above embodiment, a control cabinet 11 is installed on one side of the top of the main body 1. The feeding conveyor 201, electric slide table 202, electric turntable 501, photoelectric proximity switch 505, lifting cylinder 603, weighing device 604, positioning cylinder 801, cover cylinder 803, cover clamping cylinder 805, top pressing cylinder 901, bottom pressing cylinder 903, feeding cylinder 1001 and feeding conveyor 1003 are all electrically connected to the control cabinet 11 to facilitate the automated operation of the equipment. Coal powder buckets 3 are placed on the top of the feeding conveyor 201 and the feeding conveyor 1003. The top of the coal powder buckets 3 and the inside of the cover rack 806 are connected to bucket lids 4 to facilitate the sealing of coal powder.

[0049] Example 2:

[0050] Based on the above embodiment one, the following settings are now implemented to increase stability during transportation.

[0051] See Figure 2 and Figure 3In the above embodiment, the transfer component 5 also includes four damping springs 506 connected to both sides inside the main body 1. One end of each of the four damping springs 506 is connected to a roller frame 507. The four damping springs 506 and the roller frame 507 are arranged in a circular array. The damping springs 506 and the roller frame 507 work synchronously. The rollers on the roller frame 507 will be in contact with the outer wall of the rotating coal powder bucket 3. If the coal powder bucket 3 is displaced, the damping springs 506 will undergo elastic displacement along their own axial direction, driving the roller frame 507 to apply a reverse thrust to the coal powder bucket 3, pushing the displaced coal powder bucket 3 back to the reference position, reducing the impact of bucket displacement on subsequent processes.

[0052] Example 3:

[0053] Based on the above embodiment one, the following settings are now made for ease of use.

[0054] See Figure 1 and Figure 2 In the above embodiments, both the feeding conveyor 201 and the unloading conveyor 1003 are powered roller conveyors. The feeding conveyor 201 and the unloading conveyor 1003 are powered roller conveyors, which, with their superior load-bearing capacity, stably support the coal powder bucket 3 and prevent the bucket from tilting or the conveying from jamming due to insufficient load during the conveying process.

[0055] The implementation principle of this utility model is as follows: First, after completing the preliminary preparation operations, the staff opens the door of the upper cover 802 and stacks the barrel lids 4 into the lid storage rack 806. At this time, the bottom of the stacked barrel lids 4 is supported and limited by the baffle plate 804 to prevent the barrel lids 4 from falling directly into the main body of the equipment 1. Then, the staff connects the external pneumatic conveyor used to transport coal powder to the powder inlet 601, and a discharge valve is set between the pneumatic conveyor and the powder inlet 601 to control the on and off. Finally, the staff turns on the equipment and links the external pneumatic conveyor through the control cabinet 11.

[0056] After preparation, the equipment enters the automated operation process; the feeding conveyor 201 operates, conveying the coal powder bucket 3 into the equipment body 1; then the feeding conveyor 201 stops operating, and the electric slide table 202 drives the feeding push plate 203 to move horizontally, pushing the coal powder bucket 3 from the conveyor towards the turntable body 502. At this time, the feeding bridge 204 fills the gap between the feeding conveyor 201 and the turntable body 502, reducing the risk of the coal powder bucket 3 falling. Finally, the coal powder bucket 3 is pushed into the positioning plate 503 on the top of the turntable body 502. The positioning plate 503 automatically calibrates the reference position of the coal powder bucket 3 through its own n-shaped structure and the sloping design on both sides, laying the foundation for precise docking in subsequent processes; after feeding is completed, the electric slide table 202 drives the feeding push plate 203 to move horizontally in the opposite direction to reset, and the feeding conveyor 201 resumes operation to prepare for the next feeding.

[0057] Subsequently, the transfer component 5 begins operation. The electric turntable 501 drives the turntable body 502 to rotate slowly, causing the coal powder bucket 3 inside the positioning plate 503 to revolve, realizing cross-station transfer. The slow rotation avoids generating large centrifugal forces that could cause the coal powder bucket 3 to shift. The eight positioning plates 503 on the top of the turntable body 502 are arranged in a staggered ring array. Except for the gap between the station of the capping unloading component 10 and the station of the loading component 2, which does not contain the coal powder bucket 3, the other seven positioning plates 503 all carry the coal powder bucket 3, thus achieving continuous transfer and providing support for subsequent continuous packaging. During this process, the damping spring 506 and the roller frame 507 work synchronously. The rollers on the roller frame 507 will be in contact with the outer wall of the revolving coal powder bucket 3. If the coal powder bucket 3 shifts position, the damping spring 506 will elastically displace along its own axis, causing the roller frame 507 to apply a reverse thrust to the coal powder bucket 3, pushing the shifted coal powder bucket 3 back to the reference position, reducing the impact of bucket shift on subsequent processes.

[0058] Meanwhile, the photoelectric proximity switch 505 works in conjunction with the eight sensing plates 504 on the turntable body 502 to detect the rotation angle of the turntable body 502 in real time, ensuring that the coal powder bucket 3 can accurately correspond to the coal powder loading component 6, the top cover component 8, the capping component 9, and the unloading component 10 each time the turntable stops rotating. The four ultrasonic sensors 508 on the top of the hanger 7 simultaneously detect whether there is a coal powder bucket 3 at the four stations of the unloading component 2, the coal powder loading component 6, the top cover component 8, the capping component 9, and the unloading component 10. If there is no bucket at the station of the coal powder loading component 6, the top cover component 8, the capping component 9, and the unloading component 10, the sensor will send a signal to the control cabinet 11, and the control cabinet 11 will then control the corresponding component to temporarily not start, avoiding energy waste and equipment failure caused by idling. If there is a bucket at the station of the unloading component 2 before unloading, the control cabinet 11 will alarm and stop the machine, and the staff will need to manually remove the bucket. If there is no bucket at the station of the unloading component 2, the unloading operation will proceed normally.

[0059] When the pulverized coal bin 3 rotates with the turntable body 502 to the pulverized coal loading station, the pulverized coal loading component 6 is activated; the lifting cylinder 603 first extends upward, driving the weighing device 604 through the round hole at the bottom of the turntable body 502 until it is tightly fitted with the bottom of the pulverized coal bin 3; the weighing device 604 then automatically resets to zero, removing the weight of the pulverized coal bin 3, i.e., removing the gross weight, to ensure that subsequent measurement is only based on the weight of the pulverized coal; then, an external pneumatic conveyor connects to the pulverized coal inlet 601, conveying the pulverized coal into the pulverized coal bin 3. During this process, the dust brush... 602 is positioned close to the pulverized coal bucket 3 to reduce dust generation inside the main body 1 when pulverized coal falls, thereby reducing material loss and environmental impact. Simultaneously, the weighing device 604 monitors the weight change of the pulverized coal bucket 3 in real time. When the weight reaches the preset value, indicating that the pulverized coal is fully loaded, the weighing device 604 sends a signal to the control cabinet 11. The control cabinet 11 then controls the pneumatic conveyor to stop feeding pulverized coal. Subsequently, the lifting cylinder 603 retracts downward, causing the weighing device 604 to move down and reset, thus preventing the weighing device 604 from obstructing the subsequent rotation and transfer of the pulverized coal bucket 3.

[0060] After the pulverized coal bucket 3 is filled with pulverized coal, it revolves with the turntable body 502 to the upper cover station, and the upper cover assembly 8 begins to operate. The two positioning cylinders 801 first extend towards the pulverized coal bucket 3, pushing the pulverized coal bucket 3 to further calibrate its position and reduce the alignment deviation when the lid 4 falls. Then, the lid clamping cylinder 805 is activated, clamping the second lid 4 from the bottom up in the lid storage rack 806 to prevent the stacked lids 4 from falling as a whole. Subsequently, the upper cover cylinder 803 drives the baffle plate 804 to move horizontally, so that the baffle plate 804... 04 Remove the bottom of the bottom cover 4, and the bottom cover 4 falls to the top of the coal powder bucket 3 under the influence of gravity; after the cover is installed, the cover cylinder 803 immediately drives it to move and reset, returning to the bottom of the remaining stacked cover 4 for support; finally, the cover clamping cylinder 805 releases the clamp on the second cover 4, and the remaining cover 4 falls one position under the action of gravity, preparing for the next cover installation, while the positioning cylinder 801 retracts and resets, ending the positioning of the coal powder bucket 3;

[0061] The coal powder bucket 3, with its top cover completed, continues to revolve with the turntable body 502 to the capping and unloading station. The capping assembly 9 starts first; the top pressure cylinder 901 extends upward, driving the top pressure plate 902 to move upward, applying upward pressure to the bottom of the coal powder bucket 3; simultaneously, the bottom pressure cylinder 903 extends downward, driving the bottom pressure frame 904 to move downward, applying downward pressure to the bucket cover 4 on top of the coal powder bucket 3; through bidirectional synchronous pressure, the bucket cover 4 and the coal powder bucket 3 are tightly fastened, reducing the problem of insecure sealing and completing the capping and sealing operation; after the capping is completed, the unloading assembly 10 starts; the unloading assembly 901 starts... The material cylinder 1001 drives the material pusher plate 1002 to move towards the coal powder bucket 3, pushing the sealed coal powder bucket 3 from the positioning plate 503 to the top of the material conveyor 1003; finally, the control cabinet 11 controls the operation of the material conveyor 1003 to send the sealed coal powder bucket 3 out of the main body of the equipment 1, completing the entire automatic coal powder sealing process; the feeding conveyor 201 and the discharging conveyor 1003 adopt a powered roller conveyor, which, with its superior load-bearing capacity, stably supports the coal powder bucket 3, avoiding the bucket tilting or conveying jamming due to insufficient load during the conveying process.
