Description

Technical Field

[0001] This application relates to the field of lithium battery metal powder processing equipment technology, specifically to an anti-clogging feeding station for lithium battery metal powder processing. Background Technology

[0002] A lithium battery is a battery that contains lithium (including metallic lithium, lithium alloys, lithium ions, and lithium polymers) in its electrochemical system. Lithium batteries can be broadly classified into two categories: lithium metal batteries and lithium-ion batteries. Lithium metal batteries are typically non-rechargeable and contain metallic lithium. Lithium-ion batteries do not contain metallic lithium and are rechargeable. Lithium batteries are widely used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants; uninterruptible power supplies for telecommunications; and in power tools, electric bicycles, electric motorcycles, electric cars, military equipment, aerospace, and many other fields. Due to their unique performance advantages, lithium-ion batteries have been widely used in portable electronic devices such as laptops, cameras, and mobile communications. Currently, high-capacity lithium-ion batteries are being tested in electric vehicles, becoming one of the main power sources for 21st-century electric vehicles, and will also be used in satellites, aerospace, and energy storage. With energy scarcity and global environmental pressures, lithium batteries are now widely used in the electric vehicle industry, especially with the emergence of lithium iron phosphate batteries, which has further promoted the development and application of the lithium battery industry.

[0003] Patent CN 213699750 U discloses an anti-clogging material mixing device for powder metallurgy processing. The device includes a mixing unit. When material is fed into the inner cavity of the feed inlet through a spiral shaft, an upper cam and a lower cam are installed on one side of the outer surface of the spiral shaft. When the spiral shaft rotates, it drives the upper cam and the lower cam to rotate. When the upper cam and the lower cam rotate, they drive the connecting assembly to move. The connecting assembly enables the lifting rod to move up and down. The lifting rod moves up and down in the inner cavity of the material, thereby preventing blockage when the material is fed. The upper cam and the lower cam work together, and the up-and-down movement provides a better anti-clogging effect. The applicant's prior patent application CN 221543382 U discloses an adjustable ton bag feeding device, belonging to the field of ton bag feeding stations. Its key technical features include a support frame with a feeding box mounted on it, several tapping mechanisms mounted on the support frame, each tapping mechanism including a base, a mounting plate rotatably connected to the base, a tapping cylinder mounted on the mounting plate, a positioning component for adjusting the angle of the mounting plate between the base and the mounting plate, and the tapping mechanisms slidably mounted on the support frame. The support frame also has an adjusting component for fixing the position of the tapping mechanisms. This utility model, by setting the positioning component and the adjusting component, allows the tapping mechanisms to be adjusted on the support frame, and the tapping cylinders to be flexibly adjusted to any angle, meeting the needs of ton bags of different sizes, thus offering greater applicability and higher utilization. However, this equipment can only meet the feeding requirements of products with general flowability. For lithium battery metal powder materials that are heavy, difficult to handle, and prone to clumping due to their high humidity, stickiness, and small particle size, it is more likely to cause slow feeding and blockage. In particular, the material at the bottom of the ton bag is more difficult to discharge under heavy pressure for a certain period of time. Existing feeding and conveying devices are difficult to meet the feeding requirements of such heavy ton bags. Summary of the Invention

[0029] Reference Figure 1-8 A non-clogging feeding station for processing lithium battery metal powder includes a frame 1, a crushing chamber 2, a feeding mechanism 3, an auxiliary feeding mechanism 4, and a control box (not shown). The crushing chamber 2 is located at the lower part of the frame 1, the auxiliary feeding mechanism 4 is located at the top of the frame 1, and the feeding mechanism 3 is located above the crushing chamber 2 and connected to the frame 1. The crushing chamber 2 is provided with a feed inlet 21, a discharge outlet 22, a distribution grid 23, a chamber door 24, a pushing assembly 25, and a bag clamping assembly 26. The feed inlet 21 and the discharge outlet 22 are positioned opposite each other at the upper and lower ends of the crushing chamber 2. The distribution grid 23 is laid horizontally inside the crushing chamber 2. The chamber door 24 is located on the front of the crushing chamber 2. The bag clamping assembly 26 is located between the crushing chamber 2 and the feeding mechanism 3. The pushing assembly 25 is provided with a pushing plate 251 and a pushing cylinder 252. The pushing plate 251 is located on the upper surface of the distribution grid 23. The pushing cylinder 252 is located on one side of the crushing chamber 2 and connected to the frame 1, with the cylinder rod passing through the crushing chamber 2 and connected to the pushing plate 251. The bag clamping assembly 26 is provided with a bag clamping ring 261 and a bag clamping cylinder 262. The bag clamping ring 261 is positioned opposite to the feed inlet 21. The bag clamping cylinder 262 is located on both sides of the crushing chamber 2 and connected to the bag clamping ring 261. The material-tapping mechanism 3 is provided with a discharge platform 31, a tapping cylinder 32 and an adjusting cylinder 33. The discharge platform 31 is located above the bag clamping ring 261. The center of the discharge platform 31 is provided with a discharge port 311 opposite to the feed port 21. The tapping cylinder 32 is located around the discharge platform 31 and its lower end is hinged to the frame 1. The lower end of the adjusting cylinder 33 is hinged to the frame 1 and the cylinder rod is connected to the upper part of the tapping cylinder 32. The auxiliary feeding mechanism 4 includes a bag-lifting cylinder 41, a weight sensor 42, a hook 43, a longitudinal adjustment assembly 44, a transverse adjustment assembly 45, and a discharge assembly 46. Four sets of bag-lifting cylinders 41 are symmetrically arranged above the discharge platform 31. The cylinder rod of each set of bag-lifting cylinders 41 is connected to the hook 43 via the weight sensor 42. Two sets of bag-lifting cylinders 41 are respectively arranged on the longitudinal adjustment assemblies 44 on both sides. The transverse adjustment assembly 45 is mounted on the frame 1. Adjustment component 44 is mounted on horizontal adjustment component 45; unloading component 46 is provided with unloading motor 461, unloading rod 462 and unloading cylinder 463. Unloading motor 461 is located directly above unloading port 311. Unloading rod 462 is connected to unloading motor 461. Unloading cylinder 463 is located on both sides of unloading motor 461 and is connected to unloading motor 461 through motor plate 4611. Unloading cylinder 463 is provided with unloading frame 4631 and connected to frame 1.

[0030] The longitudinal adjustment assembly 44 includes a guide plate 441, a longitudinal lead screw 442, a longitudinal slider 443, a longitudinal motor 444, and a mounting frame 445. The guide plate 441 is connected to the transverse adjustment assembly 45. The longitudinal lead screw 442 is mounted on the guide plate 441. The longitudinal slider 443 and the bag-lifting cylinder 41 are respectively fixed to the inner sides of the upper and lower ends of the mounting frame 445. The longitudinal slider 443 is connected to the longitudinal lead screw 442. The guide plate 441 is located between the longitudinal slider 443 and the bag-lifting cylinder 41. The longitudinal motor 444 is mounted on one end of the longitudinal lead screw 442 and connected to the frame 1. The spiral directions of the longitudinal lead screw 442 corresponding to the strokes of the two sets of bag-lifting cylinders 41 mounted on the longitudinal adjustment assembly 44 on the same side are opposite.

[0031] The longitudinal slider 443 and the bag-lifting cylinder 41 are respectively fixed to the inner side of the upper and lower ends of the mounting frame 445. The guide plate 441 is located between the longitudinal slider 443 and the bag-lifting cylinder 41. The gap between the longitudinal slider 443 and the bag-lifting cylinder 41 forms the slide of the guide plate 441, so that the longitudinal slider 443 slides smoothly on the longitudinal lead screw 442.

[0032] The longitudinal adjustment component 44 is used to adjust the longitudinal distance of the hook 43. On the one hand, it is to adapt to ton bags of different widths and sizes. On the other hand, it is to shake and sway the bag body. Combined with the lifting cylinder 41, it can lift and lower the bag body to adjust according to the amount of material in the ton bag. When there is little material, lifting the ton bag will cause the material to gather at the bag mouth, which is conducive to discharge. By shaking the ton bag up and down, the material in the bag can be loosened, which is conducive to unloading.

[0033] The lateral adjustment assembly 45 includes a lateral lead screw 451, a lateral slider 452, a lateral motor 453, a guide rod 454, and a guide block 455. The guide rods 454 are respectively located on the front and rear sides of the frame 1. The guide rods 454 are connected to the guide plate 441 of the longitudinal adjustment assembly 44 through the guide block 455. There are two sets of the lateral lead screw 451, lateral slider 452, and lateral motor 453, which are located on the front and rear sides of the frame 1, or respectively on the front and rear sides. The lateral lead screw 451 is connected to the frame 1. One set of lateral sliders 452 is located on the lateral lead screw 451 and connected to the guide plate 441 of the longitudinal adjustment assembly 44 on one side. The other set of lateral sliders 452 is located on the lateral lead screw 451 and connected to the guide plate 441 of the longitudinal adjustment assembly 44 on the other side. The lateral motor 453 is located at one end of the lateral lead screw 451 and connected to the frame 1.

[0034] The lateral adjustment component 45 has the same function as the longitudinal adjustment component 44, and works with the longitudinal adjustment component 44 to improve the feeding speed and enhance the feeding effect.

[0035] The unloading rod 462 is provided with a stirring blade 4621. The stirring blade 4621 is "S" shaped, and the upper and lower parts of the "S" shaped stirring blade 4621 have opposite spiral directions. There are at least 3 stirring blades 4621. The stirring blade 4621 is provided with a fixing ring 4622, which is located on the upper, middle and lower parts of the stirring blade 4621.

[0036] When the mixing blade 4621 of the discharge rod 462 rotates forward, it can push the material at the bottom downward and increase the discharge volume, while pushing the material at the top upward and reducing the compression on the material at the bag opening. This can loosen the bag opening, unlike the existing mixing blades which stir downward as a whole, causing the material to accumulate at the bag opening and making the bag opening more blocked. During the mixing process, the discharge cylinder 463 moves up and down, which can loosen the material in the entire ton bag and gradually discharge it to the bag opening.

[0037] The spiral height of the upper part of the "S"-shaped stirring plate 4621 is less than that of the lower part, with a preferred height ratio of 1:3; the spiral angle of the upper part of the "S"-shaped stirring plate 4621 is less than that of the lower part, with the spiral angle of the upper part being 45°-60° and the spiral angle of the lower part being 60°-75°.

[0038] The frame 1 is provided with a first frame 11 and a second frame 12. The crushing chamber 2 and the feeding mechanism 3 are provided on the first frame 11. The auxiliary feeding mechanism 4 is provided on the second frame 12. The second frame 12 is provided with a rotating brake wheel (not shown).

[0039] The pushing cylinder 252, bag clamping cylinder 262, tapping cylinder 32, adjusting cylinder 33, bag lifting cylinder 41, weight sensor 42, longitudinal motor 444, transverse motor 453, unloading motor 461 and unloading cylinder 463 are electrically connected to the control box.

[0040] The main purpose of the "S"-shaped agitator 4621 is to quickly discharge materials from the ton bag. Therefore, the spiral height of the lower half of the "S"-shaped agitator 4621 should be greater, and the spiral angle should be larger, so that the discharge speed is greater when rotating at the same angle, thus increasing the discharge volume.

[0041] The curved shape of the mixing blade 4621 is designed to improve mixing efficiency and quality. The curved shape of the mixing blade 4621 generates greater centrifugal and cutting forces during mixing, thus more effectively mixing materials. This design allows the mixing blade 4621 to not only cut materials during rotation but also generate a large amount of energy through collisions, which is rapidly transferred to the surrounding materials, causing disturbance and mixing throughout the entire material system. Furthermore, the upper surface of the impeller of the curved mixing blade 4621 adopts a hyperboloid structure formed by rotating a hyperbola around the impeller axis. This design maximizes the combination of fluid characteristics and mechanical motion, allowing the materials to reach equilibrium under motion.

[0042] In short, the curved shape of the mixing blade 4621 enhances the mixing effect and improves mixing efficiency. The curved shape of the mixing blade 4621 better adapts to the shape of the mixing container, ensuring that materials are fully mixed during the mixing process, reducing dead zones, and thus improving mixing efficiency. The curved design increases the contact area between the mixing blade 4621 and the material, making the mixing more uniform, especially for high-viscosity or easily agglomerated materials, where the effect is more significant. In addition, spatial layout is an important consideration in the design of mixing equipment. The design of the curved mixing blade 4621 can better adapt to the overall layout of the mixing equipment, reducing the space occupied by the equipment.

[0043] The ton bag containing lithium battery metal powder is placed on the feeding mechanism 3 and hung by the hook 43 of the auxiliary feeding mechanism 4. Since the ton bag is a heavy packaging bag, it is equipped with double openings at both the top and bottom to prevent it from being difficult to turn upside down for unloading if one end is open. The top opening of the ton bag is opened, and the unloading rod 462 is inserted into the bag. The bottom opening of the ton bag is clamped to the feed port 21 by the bag clamping assembly 26.

[0044] During the unloading process, the side of the bag opening is patted by the patting cylinder 32 to squeeze, break, and clear the internal material. As needed, the patting can be set to work simultaneously, in turn, or alternately, or a combination of the above methods can be used for sequential patting. The patting process can be coordinated with the bag lifting action and the movement of the longitudinal adjustment component 44 and the lateral adjustment component 45 to lift, lower, and shake the bag to assist in unloading. At the same time, the unloading motor 461 drives the unloading rod 462 to rotate, loosening and clearing the material inside the bag, especially at the bag opening, and controlling the unloading cylinder 463 to lift and lower to improve the clearing effect.

[0045] After the material enters the crushing chamber 2, which is a closed chamber, the dust generated during the unloading process is prevented from spreading. The distribution grid 23 crushes the agglomerated material, and the pushing component 25 spreads the material out to avoid stacking and increase the feeding speed. The pushing action also has a certain crushing effect on the agglomerated material.

[0046] The longitudinal slider 443 and the bag-lifting cylinder 41 are respectively fixed to the inner side of the upper and lower ends of the mounting frame 445. The guide plate 441 is located between the longitudinal slider 443 and the bag-lifting cylinder 41. The gap between the longitudinal slider 443 and the bag-lifting cylinder 41 forms the slide of the guide plate 441, so that the longitudinal slider 443 slides smoothly on the longitudinal lead screw 442.

[0047] The longitudinal adjustment component 44 is used to adjust the longitudinal distance of the hook 43. On the one hand, it is to adapt to ton bags of different widths and sizes. On the other hand, it is to shake and sway the bag body. Combined with the lifting cylinder 41, it can lift and lower the bag body to adjust according to the amount of material in the ton bag. When there is little material, lifting the ton bag will cause the material to gather at the bag mouth, which is conducive to discharge. By shaking the ton bag up and down, the material in the bag can be loosened, which is conducive to unloading.

[0048] The lateral adjustment component 45 has the same function as the longitudinal adjustment component 44, and works with the longitudinal adjustment component 44 to improve the feeding speed and enhance the feeding effect.

[0049] The unloading rod 462 is provided with a stirring blade 4621. The stirring blade 4621 is "S" shaped, and the upper and lower parts of the "S" shaped stirring blade 4621 have opposite spiral directions. There are at least 3 stirring blades 4621. The stirring blade 4621 is provided with a fixing ring 4622, which is located on the upper, middle and lower parts of the stirring blade 4621.

[0050] When the mixing blade 4621 of the discharge rod 462 rotates forward, it can push the material at the bottom downward and increase the discharge volume, while pushing the material at the top upward and reducing the compression on the material at the bag opening. This can loosen the bag opening, unlike the existing mixing blades which stir downward as a whole, causing the material to accumulate at the bag opening and making the bag opening more blocked. During the mixing process, the discharge cylinder 463 moves up and down, which can loosen the material in the entire ton bag and gradually discharge it to the bag opening.

[0051] The main purpose of the "S"-shaped agitator 4621 is to quickly discharge materials from the ton bag. Therefore, the spiral height of the lower half of the "S"-shaped agitator 4621 should be greater, and the spiral angle should be larger, so that the discharge speed is greater when rotating at the same angle, thus increasing the discharge volume.

[0052] The curved shape of the mixing blade 4621 is designed to improve mixing efficiency and quality. The curved shape of the mixing blade 4621 generates greater centrifugal and cutting forces during mixing, thus more effectively mixing materials. This design allows the mixing blade 4621 to not only cut materials during rotation but also generate a large amount of energy through collisions, which is rapidly transferred to the surrounding materials, causing disturbance and mixing throughout the entire material system. Furthermore, the upper surface of the impeller of the curved mixing blade 4621 adopts a hyperboloid structure formed by rotating a hyperbola around the impeller axis. This design maximizes the combination of fluid characteristics and mechanical motion, allowing the materials to reach equilibrium under motion.

[0053] In short, the curved shape of the mixing blade 4621 enhances the mixing effect and improves mixing efficiency. The curved shape of the mixing blade 4621 better adapts to the shape of the mixing container, ensuring that materials are fully mixed during the mixing process, reducing dead zones, and thus improving mixing efficiency. The curved design increases the contact area between the mixing blade 4621 and the material, making the mixing more uniform, especially for high-viscosity or easily agglomerated materials, where the effect is more significant. In addition, spatial layout is an important consideration in the design of mixing equipment. The design of the curved mixing blade 4621 can better adapt to the overall layout of the mixing equipment, reducing the space occupied by the equipment.

[0054] The crushing chamber 2, the feeding mechanism 3, and the auxiliary feeding mechanism 4 are set on different frames 1 to reduce the impact of the vibration generated by the pneumatic hammer 29 and the feeding mechanism 3 on the weight sensor 42 on the auxiliary feeding mechanism 4; the rotating brake wheel is used to move the second frame 12 to facilitate the hoisting of the ton bag onto the unloading platform 31 of the first frame 11, or to the height of the hook 43 of the auxiliary feeding mechanism 4, and then move the platform above the unloading platform 31.

[0055] In some embodiments of this application, the unloading platform 31 is provided with a support leg 312, a support rod 313 and a feeding support 314. The support leg 312 and the tapping cylinder 32 are respectively arranged on the frame 1. The support rod 313 is arranged on the upper end of the support leg 312. The feeding support 314 is arranged opposite to the feed port 21 and connected to the support rod 313. At least one of the tapping cylinder 32, the adjusting cylinder 33 and the support leg 312 is provided with a pressure sensor 5 between itself and the frame 1.

[0056] The ton bag is received by the feeding support 314. The bag opening passes through the discharge port 311 in the center of the feeding support 314 and the bag clamping ring 261 at the bottom. The bag clamping cylinder 262 descends to press the bag opening tightly against the feed port 21. The pressure sensor 5 is used to sense the weight of the material in each direction of the unloading platform 31. When the material in a certain direction is heavier than in other directions, it indicates that the material discharge speed on that side is slow. Then, the tapping cylinder 32 on that side is activated or its tapping frequency is increased. At the same time, the discharge angle is adjusted up and down by the adjusting cylinder 33 to find different discharge angles until the pressure in each direction is equal, and the original tapping steps are resumed. The pressure sensor 5 on the tapping cylinder 32 and the adjusting cylinder 33 can detect the tapping direction. If the pressure value detected at a certain position is low, it indicates that the angle is too large and the material is not being effectively tapped; the tapping angle needs to be adjusted downwards. Similarly, if, when the angles of all cylinders are the same, the pressure ratio of the adjusting cylinder 33 to the tapping cylinder 32 in a certain direction is less than the values ​​in other directions, it indicates that the tapping cylinder 32 in that direction is obstructed by clumps and has a short propulsion length; in this case, the frequency of the tapping cylinder 32 in that direction should be increased to break up the clumps. If the pressure values ​​of the adjusting cylinder 33 and the tapping cylinder 32 in a certain direction are greater than those in other directions, it indicates that the material is shifting to that side or the material feeding speed on that side is slow; in this case, the frequency of the tapping cylinder 32 should be increased, or the angle of the tapping cylinder 32 should be increased to push the material to the other side. The pressure sensor 5 and the weight sensor 42 jointly acquire the material status in the ton bag and comprehensively control the operation of the tapping mechanism 3.

[0057] In some embodiments of this application, the tapping cylinder 32 is provided with a support plate 321, a cylinder plate 322, a tapping plate 323, and a rubber pad 324. The support plate 321 is connected to the frame 1, the cylinder plate 322 is hinged to the upper support plate 321, the tapping cylinder 32 is fixed on the cylinder rod, the tapping plate 323 is provided at the front end of the tapping cylinder 32, and the rubber pad 324 is provided on the tapping plate 323. The front end of the adjusting cylinder 33 is connected to the cylinder plate 322.

[0058] The tapping cylinder 32 achieves different tapping methods for the material in the ton bag through the control box, and controls it in conjunction with the weight sensor 42 and the pressure sensor 5. Together with the auxiliary feeding mechanism 4, it realizes the feeding of material into the ton bag.

[0059] In some embodiments of this application, the pusher plate 251 is provided with a silicone plate, the lower end of which is arc-shaped or triangular.

[0060] The pusher plate 251 flattens the material on the distribution grid 23 and can also crush and squeeze the material, improving the separation effect of the material; the silicone plate reduces wear, and the arc or triangle shape can push and squeeze the material when pushing back and forth, improving the material feeding speed.

[0061] In some embodiments of this application, the door 24 is provided with an observation window 241 and a glove opening 242. A scraper 2411 is provided through the center of the observation window 241. The outer end of the scraper 2411 is provided with a rotating rod 2412 and the inner end is provided with a scraper 2413 that fits into the observation window 241. A gasket 211 is provided between the feed inlet 21 and the bag clamping ring 261.

[0062] The observation window 241 is used to observe the material condition inside the crushing chamber 2. The scraper 2411, controlled by the rotating rod 2412, cleans the dust inside the observation window 241 using the scraper 2413. Glove openings 242 are located on both sides of the observation window 241 and are equipped with operating gloves for cleaning materials that the pushing assembly 25 cannot handle. The gasket 211 better clamps the bag opening and prevents damage.

[0063] In some embodiments of this application, the crushing chamber 2 is further provided with a small door 27, an exhaust filter 28 and a pneumatic hammer 29. The small door 27 is located on one side of the crushing chamber 2, the exhaust filter 28 is located on the rear side of the crushing chamber 2, and the pneumatic hammer 29 is located on both sides of the discharge port 22. A vibration damping pad (not shown) is provided between the pressure sensor 5 or the tapping cylinder 32, the adjusting cylinder 33, the support leg 312 and the frame 1.

[0064] The small door 27 can quickly process the material in the crushing chamber 2; the exhaust filter 28 discharges the air pressure generated during the feeding process, which is beneficial for material feeding; the pneumatic hammer 29 can assist the material to pass through the distribution grid 23 and the discharge port 22. The vibration damping pad reduces the impact of the vibration of the pneumatic hammer 29 on the weight and pressure value.

[0065] During operation, the ton bag is hoisted onto the unloading platform 31, and the bag opening is pressed against the feed inlet 21 by the bag clamping ring 261; or it is hoisted to the height of the hook 43 of the auxiliary unloading mechanism 4, and then the platform is moved above the unloading platform 31, the height of the ton bag is lowered, and the bag opening is pressed against the feed inlet 21 by the bag clamping ring 261; the upper opening of the ton bag is opened, the unloading motor 461 is turned on, the unloading rod 462 is rotated, and the unloading cylinder 463 is lowered simultaneously, so that the unloading rod 462 is slowly inserted into the material in the ton bag, and the stirring plate 4621 is located at the lower opening of the ton bag. During material feeding, the pushing component 25 and the tapping mechanism 3 are activated to open the bottom opening of the ton bag for feeding. The pneumatic hammer 29 is activated simultaneously. The tapping method of the tapping cylinder 32 can be configured to tap simultaneously, tap sequentially, or tap alternately as needed, or a combination of the above methods can be used for alternating tapping. The tapping process can be coordinated with the bag lifting action and the movement of the longitudinal adjustment component 44 and the lateral adjustment component 45 to lift, lower, and shake the bag to assist in material feeding. At the same time, the unloading motor 461 drives the unloading rod 462 to rotate, clearing the material at the bag opening and controlling the unloading cylinder 463 to lift and lower to improve the material loosening effect.

[0066] During the feeding process, pressure sensor 5 mainly controls the action and angle of the tapping cylinder 32. If the pressure sensor 5 has a larger weight in a certain direction, the tapping cylinder 32 in the corresponding direction will tap at a higher frequency. Meanwhile, weight sensor 42 mainly controls the action of the bag-lifting cylinder 41. If the weight sensor 42 has a larger weight in a certain direction, it indicates that there is more material in that direction, so it will be lifted upwards, causing the material to shift to other directions. The tapping mechanism 3 and the auxiliary feeding mechanism 4 also interact. Under the combined action of pressure sensor 5 and weight sensor 42, if the values ​​of pressure sensor 5 and weight sensor 42 are both large in a certain direction, the adjusting cylinder 33 will adjust the angle of the tapping cylinder 32 to increase, thereby pushing the material on that side to the other side through tapping. When there is a lot of material in the ton bag, the auxiliary feeding mechanism 4 controls the longitudinal adjustment component 44 and the lateral adjustment component 45 to pull the ton bag outward. When the material decreases, the hook 43 is controlled to retract inward, and the bag lifting cylinder 41 moves upward. As the material decreases, the ton bag is lifted upward, causing the material to gather towards the center, which is conducive to feeding. During the feeding process, especially in the later stage, the bag body is shaken by simultaneously controlling the longitudinal adjustment component 44 and the lateral adjustment component 45, which promotes feeding and prevents the material from sticking to the inside of the bag. The bag lifting cylinder 41 moves up and down to make the material fall. When the weight sensor 42 or the pressure sensor 5 detects a sudden decrease in the rate of weight drop, it indicates that a blockage has occurred. At this time, the unloading motor 461 and the unloading cylinder 463 are started. The unloading cylinder 463 moves up and down, causing the stirring plate 4621 to penetrate the upper surface of the material in the ton bag and enter the feed inlet 21 to clear the material. In the absence of material blockage, the position of the ton bag can be adjusted by the longitudinal adjustment component 44 and the transverse adjustment component 45, while controlling the unloading cylinder 463 to move up and down, so that the stirring plate agitates the material inside the bag, loosening the material on the one hand and breaking up the lumpy material on the other, thereby improving the feeding speed and effect.
