[0017] To enable those skilled in the art to better understand the technical solutions of this disclosure, the following detailed, clear, and complete description of this disclosure is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this disclosure and are not intended to limit it.

[0018] In the description of this application, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0019] Those skilled in the art should understand that in the disclosure of this application, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0020] Example 1: This embodiment provides a fiber foreign matter sorting machine for using powder materials used in the production of negative or positive electrodes for lithium-ion batteries, such as... Figures 1-4 As shown, it includes: Foreign object collection system 1, used to collect and transport foreign objects; Discharge component 2 is used to generate electrostatic charge and produce an adsorption force on fibrous foreign matter; Electromagnetic vibrating feeder 3 is used for conveying materials; The electromagnetic vibrating feeder 3 includes a conveying channel 32, which has an installation port 31 and a tape inlet 321. The discharge assembly 2 is located on the installation port 31. The foreign object collection system 1 includes a frame 11 and an unwinding roller 12 and a winding roller 13 mounted on the frame 11. The unwinding roller 12 has a tape roll 19, and the tape on the tape roll 19 passes through the tape inlet 321 and connects to the winding roller 13. The tape inlet 321 extends through both sides of the conveying channel 32. The projection of the discharge assembly 2 on the horizontal plane covers the projection of the installation port 31 on the horizontal plane.

[0021] The unwinding roller 12 is used for unwinding the conveyor belt, and the winding roller 13 is used for winding the conveyor belt. The belt inlet 321 is used to pass the conveyor belt into the conveyor channel 32 from one side, collect fibers in the conveyor channel 32 using the surface of the belt, and then send the fiber-adhered belt out from the belt inlet 321 on the other side. The discharge assembly 2 is used to generate and accumulate electrostatic charge. The mounting port 31 is opened on the conveyor channel 32, which can realize electrostatic sorting while conveying, improving work efficiency. The discharge assembly 2 can completely cover the mounting port 31 to prevent foreign objects in the material from escaping from the mounting port 31. During use, charge is generated and accumulated on the discharge component 2. When the material in the conveying channel 32 passes through the area below the discharge component 2, foreign objects will be removed from the material and move toward the discharge component 2 by the attraction of electrostatic charge. During this process, the foreign objects will encounter the tape surface and be stuck to the tape surface. The material will move continuously, which will cause the foreign objects in the material passing below the discharge component 2 to be continuously removed. The tape surface will also move continuously under the drive of the unwinding roller 12 and the take-up roller 13, which can prevent too many foreign objects on the tape surface and ensure the adhesion effect.

[0022] For reliable feeding, such as Figure 5 As shown, the conveying channel 32 has an inlet 322 and an outlet 323 at both ends, and a material scraper 324 is provided on the conveying channel 32, extending towards the bottom surface of the conveying channel 32. The material scraper 324 effectively prevents material accumulation during the conveying process, ensuring a more uniform and efficient feeding process for the fiber foreign matter sorting machine. In use, materials are poured into the inlet 322 in batches, or directly fed through a pipe on the production line. Excess material will be transported along the conveying channel 32, and the material scraper 324 will block the material above, thus ensuring that the material passing below the material scraper 324 maintains a uniform thickness, thereby guaranteeing the subsequent removal effect of foreign matter.

[0023] A flow interceptor 33, which can extend or retract relative to the bottom surface of the conveying channel 32, is provided between the material scraper 324 and the discharge port 323; the material scraper 324 and the flow interceptor 33 are located between the belt inlet 321 and the feed inlet 322. The design of the flow interceptor 33 can effectively control the conveying thickness of the material in the conveying channel 32, thereby improving the sorting accuracy. By adjusting the extension or retraction degree of the flow interceptor 33, the thickness of the material layer can be flexibly adjusted, ensuring a more ideal separation effect between fibers and foreign matter.

[0024] To facilitate precise control of material thickness, the intercepting plate 33 is provided with a scale for displaying the size of the space through which the conveying channel 32 can pass. The scale displays the distance between the bottom surface of the intercepting plate 33 and the bottom surface of the conveying channel 32. When the position of the intercepting plate 33 is adjusted up and down, the position of the electromagnetic vibrating feeder 3 exposed by the intercepting plate 33 will change, thereby changing the position of the scale on the intercepting plate 33 that is blocked by the electromagnetic vibrating feeder 3, thus enabling the reading of the scale.

[0025] In this embodiment, the intercepting plate 33 is located next to the material scraper 324; the intercepting plate 33 is provided with an elongated hole 331, and the electromagnetic vibrating feeder 3 is provided with a fixing post 332 that cooperates with the elongated hole 331, with the fixing post 332 passing through the elongated hole 331; the top of the intercepting plate 33 is provided with a bending part 333; the electromagnetic vibrating feeder 3 is provided with a notch that matches the cross-sectional shape of the intercepting plate 33 so that the intercepting plate 33 can extend into the conveying channel 32. The cooperation between the elongated hole 331 and the fixing post 332 facilitates the fixing of the position according to actual needs, and the design of the bending part 333 enhances the structural strength while also improving the ease of operation.

[0026] To facilitate material feeding, a feeding guide 37 with a bottom opening is also included, which is connected to the discharge port 323. The feeding guide 37 includes a funnel-shaped concentrator 371, and the discharge port 323 is located above the concentrator 371. The feeding guide 37 is used to guide the feeding of material after fiber separation. The bottom opening ensures that the material is discharged from the bottom opening, while preventing dust from spreading to the outside. The funnel-shaped concentrator 371 facilitates the concentration of material, reducing scattering and waste. The discharge port 323 is located above, ensuring that the material passes through the concentrator 371.

[0027] In this embodiment, the discharge port 323 is connected to the side of the feeding guide 37. The material enters the concentrator 371 from the side, which allows the material to slide down along the side of the concentrator 371. Compared with direct falling, this can reduce dust.

[0028] To facilitate observation of the internal working status of the conveying channel 32, an observation port 326 is provided on the conveying channel 32, and a removable cover plate 38 is provided on the observation port 326. The design of the observation port 326 allows operators to easily check the internal condition at any time, and the removable cover plate 38 can close the observation port 326 when the operator is not observing, preventing dust or other impurities from entering the conveying channel 32, and also preventing dust in the conveying channel 32 from spreading to the outside.

[0029] To reduce the impact of dust, a dust buffer chamber 328 is provided on the conveying channel 32. The dust buffer chamber 328 is located between the material scraper 324 and the feed inlet 322. Specifically, an upward protrusion is provided on the conveying channel 32 to form the dust buffer chamber 328. A small portion of the dust raised by the vertical plate 342 will pass through the dust buffer chamber 328 and diffuse within it, reducing the probability of entering the subsequent conveying channel 32 and preventing the raised dust from affecting the adhesion of the tape to foreign objects. The observation port 326 is located at the top of the dust buffer chamber 328.

[0030] In this embodiment, the cover plate 38 is located at the highest point, that is, the observation port 326 is set at a high position, which can reduce the possibility of internal dust spreading to the outside.

[0031] To maintain the cleanliness of the conveying channel 32 and reduce the impact of dust on sorting efficiency, the conveying channel 32 is provided with at least one dust removal port 327. The dust removal port 327 is used to connect to external dust collection equipment, which can effectively reduce dust in the conveying channel 32, reduce dust adhesion on the tape surface, and ensure the reliability of fiber removal from the tape.

[0032] In this embodiment, two dust removal ports 327 are provided; one dust removal port 327 is located on the cover plate 38, and the other dust removal port 327 is located on the unloading guide 37. Both dust removal ports 327 are located at the top. The cover plate 38 and the unloading guide 37 are located on both sides of the tape opening 321, which means that the two dust removal ports 327 are located on both sides of the tape opening 321, which can reduce dust from both sides of the tape opening 321, reduce dust adhesion on the tape surface, and ensure the reliability of fiber removal from the tape.

[0033] At least one material lifting plate 325 is provided on the bottom surface of the conveying channel 32. In this embodiment, three material lifting plates 325 are provided, with the middle one located at the center of the conveying channel 32, and the material lifting plates 325 on both sides arranged symmetrically relative to the middle material lifting plate 325; the material lifting plates 325 are located between the intercepting plate 33 and the discharge guide 37; the material lifting plates 325 protrude from the bottom surface of the conveying channel 32 and are perpendicular to the bottom surface of the conveying channel 32; the material lifting plates 325 are located below the conveyor belt opening 321. When the material passes through the material lifting plate 325, the material lifting plate 325 will scoop up the material at the bottom, exposing the fibrous foreign matter at the bottom of the material, thereby improving the removal effect of foreign matter.

[0034] To prevent dust from being generated by the impact of material feeding and causing dust to stick to the tape surface, the feed inlet 322 faces upward and is equipped with a material buffer baffle 34 to prevent dust from being generated by material feeding. This baffle can effectively reduce the impact force when the material falls, reduce dust, and control the dust near the feed inlet 322 to prevent it from spreading to the tape surface.

[0035] The material buffer baffle 34 includes an inclined plate 341. The height of the inclined plate 341 gradually decreases from the outer side of the feed inlet 322 to the center of the feed inlet 322, and a space is left between the bottom of the inclined plate 341 and the edge of the feed inlet 322. The design of the inclined plate 341 can effectively guide the movement of materials and reduce the impact force when the materials fall, thereby further reducing the generation of dust. The space design between the bottom of the inclined plate 341 and the edge of the feed inlet 322 ensures that the materials can enter the conveying channel 32 through this space after being guided by the inclined plate 341.

[0036] The material buffer baffle 34 also includes a vertical plate 342, which is located below the inclined plate 341. At least part of the vertical plate 342 is located above the conveying channel 32, and the vertical plate 342 is connected to both sides of the conveying channel 32. The design of the vertical plate 342 serves two purposes: first, it strengthens the structural strength of the conveying channel 32; second, it prevents dust from entering the conveying channel 32. After the material enters the conveying channel 32 through the inclined plate 341 and the feed inlet 322, some of the material falls and is lifted up, while the lifted part is located at the top of the conveying channel 32. The vertical plate 342, located at the top of the conveying channel 32, can prevent dust from passing through the top of the conveying channel 32, while the material at the bottom of the conveying channel 32 can pass through normally.

[0037] In this embodiment, the distance between the bottom surface of the vertical plate 342 and the bottom surface of the conveying channel 32 is greater than the distance between the bottom surface of the material scraper 324 and the bottom surface of the conveying channel 32.

[0038] To ensure efficient feeding, a buffer chamber 35 is provided on the feed inlet 322; a rotary valve 36 is provided between the buffer chamber 35 and the feed inlet 322; the buffer chamber 35 and the feed inlet 322 are connected by a connecting pipe 351. The buffer chamber 35 can buffer the incoming material and temporarily store it; the rotary valve 36 is used to control the material in the buffer chamber 35 to enter the feed inlet 322, so that the material can fall in an orderly manner and prevent the material from accumulating in the feed inlet 322.

[0039] like Figure 8 , Figure 9As shown, to ensure reliable foreign object collection, the foreign object collection system 1 includes a tape height adjustment device 14. Transition rollers 15 are provided between the unwinding roller 12 and the tape height adjustment device 14, and between the take-up roller 13 and the tape height adjustment device 14. The tape height adjustment device 14 includes a drive cylinder 141, a slide rail 142, a slider 143, a linkage plate 144, and at least two guide rollers 145. The two guide rollers 145 are connected to the linkage plate 144, the slide rail 142 is connected to the frame 11, the slider 143 is slidably connected to the slide rail 142, and the linkage plate 144 is connected to the slider 143. The drive cylinder 141 is used to drive the linkage plate 144 to move. In this embodiment, two guide rollers 145 are provided, located on opposite sides of the electromagnetic vibrating feeder 3. The transition rollers 15 are rotatably connected to the frame 11. The drive cylinder 141 is a three-axis, three-bar cylinder with a guide rod. The extension and retraction direction of the drive cylinder 141 is perpendicular to the axial direction of the guide rollers 145.

[0040] The tape height adjustment device 14 is used to adjust the positional deviation of foreign objects adhering to the tape, ensuring that the tape always stays on the correct path and guarantees the adhesion effect. The transition roller 15 is used to guide the direction of the tape and reduce friction and tension changes during the tape's transmission process, thereby improving the stability and service life of the entire system. The drive cylinder 141 can drive the linkage plate 144, which in turn drives the guide roller 145 to adjust its position. The slider 143 and the slide rail 142 cooperate to ensure the reliable movement of the linkage plate 144. The entire system enables stable tape conveying, and the separated foreign objects are adhered to the tape surface and then conveyed to the take-up roller 13 for collection.

[0041] The unwinding roller 12 includes an unwinding air shaft 121 and a first drive motor 122. The unwinding air shaft 121 is rotatably connected to the frame 11, and the first drive motor 122 drives the unwinding air shaft 121 to rotate. The design of the unwinding air shaft 121 takes into account the need for quick replacement of the tape roll 19. The installation and removal of the tape roll 19 can be completed through simple operations, thereby improving work efficiency and reducing downtime. This structural design not only improves the overall performance of the equipment but also provides convenience for subsequent maintenance.

[0042] like Figure 10 As shown, in this embodiment, the first drive motor 122 is connected to the frame 11; the first drive motor 122 is connected to the unwinding air shaft 121. Specifically, the first drive motor 122 is provided with a drive wheel 123, and the unwinding air shaft 121 is provided with a driven wheel 124. The drive wheel 123 and the driven wheel 124 are connected by a belt 125.

[0043] The take-up roller 13 includes a take-up air shaft 131 and a second drive motor 132. The take-up air shaft 131 is rotatably connected to the frame 11, and the second drive motor 132 is used to drive the take-up air shaft 131 to rotate. The structural design of the take-up air shaft 131 fully considers the convenience of tape recycling.

[0044] In this embodiment, the second drive motor 132 is connected to the frame 11; the second drive motor 132 is connected to the take-up air shaft 131, and its specific transmission structure is the same as that of the first drive motor 122 and the unwind air shaft 121.

[0045] To ensure reliable tape operation, the frame 11 is also equipped with a traction device 16. The traction device 16 includes a first traction roller 161, a pressure roller 162, and a third drive motor 163. Both the first traction roller 161 and the pressure roller 162 are rotatably connected to the frame 11. The third drive motor 163 drives the first traction roller 161 to rotate, and the first traction roller 161 is in contact with the pressure roller 162. The tape is positioned between the first traction roller 161 and the pressure roller 162, ensuring a firm fit between the tape and the first traction roller 161. The third drive motor 163 drives the first traction roller 161 to rotate, which in turn drives the tape, thus achieving tape traction.

[0046] To improve the traction effect, the traction device 16 further includes a second traction roller 164, which is rotatably connected to the frame 11, and the first traction roller 161 is drive-connected to the second traction roller 164. When the third drive motor 163 drives the first traction roller 161 to rotate, the first traction roller 161 synchronously drives the second traction roller 164 to rotate, and the second traction roller 164 can then drive the conveyor belt on it, thereby improving the traction effect.

[0047] In this embodiment, the first traction roller 161 is connected to the second traction roller 164 via gear meshing. Specifically, the first traction roller 161 is provided with a first gear 167, and the second traction roller 164 is provided with a second gear 168. The first gear 167 and the second gear 168 mesh.

[0048] To ensure reliable installation of the first traction roller 161, a fixing plate 111 is provided on the side of the first traction roller 161 opposite to the frame 11. The first traction roller 161 is rotatably connected to the fixing plate 111. A connecting post 112 is provided between the fixing plate 111 and the frame 11, with both ends of the connecting post 112 connected to the fixing plate 111 and the frame 11, respectively. The end of the second traction roller 164 away from the frame 11 is rotatably connected to the fixing plate 111. The design of the fixing plate 111 ensures that both ends of the first traction roller 161 and the second traction roller 164 are supported, resulting in more reliable installation.

[0049] To ensure more reliable compression of the conveyor belt by the pressure roller 162, fine-tuning components are provided at both ends of the pressure roller 162. These components are used to adjust the distance between the pressure roller 162 and the first traction roller 161. Each fine-tuning component includes a telescopic cylinder 165, the telescopic end of which is connected to the pressure roller 162. The design of the telescopic cylinder 165 allows the pressure roller 162 to extend or retract relative to the first traction roller 161, thereby adjusting the degree of compression of the conveyor belt and ensuring effective compression.

[0050] In this embodiment, one end of the telescopic cylinder 165 is connected to the frame 11 via a bracket 166, and the other end of the telescopic cylinder 165 is connected to the fixing plate 111 via a bracket 166.

[0051] To ensure reliable tape delivery, a tape breakage detection device 17 is installed on the frame 11. This device detects tape breaks, ensuring normal tape delivery within the system. In this embodiment, the tape breakage detection device 17 uses an ultrasonic sensor.

[0052] To ensure testing effectiveness, the frame 11 is equipped with an extension column 171, one end of which is fixedly connected to the frame 11. The tape breakage detection device 17 is connected to the extension column 171 via a clamp 172. The extension column 171 provides the installation position for the tape breakage detection device 17, allowing it to be installed away from the frame 11. This ensures that the tape breakage detection device 17 can be directly aligned with the center of the tape for testing, guaranteeing testing effectiveness.

[0053] The first drive motor 122, the second drive motor 132, and the third drive motor 163 are servo motors. The servo motors have built-in pressure detection and can detect the tension of the tape.

[0054] like Figure 11 As shown, a tape roll 19 is provided on the unwinding roller 12. The tape passes through two transition rollers 15, two guide rollers 145, a second traction roller 164, a first traction roller 161 and two transition rollers 15 from the end where the unwinding roller 12 is located to the take-up roller 13.

[0055] The frame 11 includes a mounting plate 113, on which a tape height adjustment hole 1131 and a traction roller disassembly hole 1132 are provided. A traction roller disassembly groove 1111 is provided on a fixing plate 111. A guide roller 145 passes through the tape height adjustment hole 1131. Both ends of the first traction roller 161 and both ends of the second traction roller 164 are respectively provided on the traction roller disassembly hole 1132 and the traction roller disassembly groove 1111.

[0056] To ensure the proper position of the tape, a tape alignment device 18 is provided on the frame 11. The tape alignment device 18 drives the unwinding roller 12 to move axially. The tape breakage detection device 17 is also used for tape position detection. The tape alignment device 18 adjusts the tape's positional deviation to ensure the tape always stays on the correct path, guaranteeing adhesion and stable unwinding and rewinding.

[0057] In this embodiment, the tape correction device 18 includes a drive component 181. The frame 11 includes a support plate 114, a guide post 115, and two movable plates 116. The two movable plates 116 are located on both sides of the support plate 114. The guide post 115 passes through the support plate 114, and its two ends are connected to the two movable plates 116 respectively. The drive component 181 is fixedly connected to the support plate 114, and the telescopic end of the drive component 181 is connected to one of the movable plates 116. The unwinding air shaft 121 and the first drive motor 122 are both connected to the movable plate 116. The drive component 181 is an electric push rod. The tape breakage detection device 17 can also detect the position of the tape. After detecting a shift in the tape position, the drive component 181 pushes the movable plate 116, causing the movable plate 116 to move synchronously with the tape roll 19, thereby adjusting the position of the tape and ensuring reliable tape delivery.

[0058] In this embodiment, the first drive motor 122, the second drive motor 132, the third drive motor 163, the drive cylinder 141, the telescopic cylinder 165, and the tape breakage detection device 17 can all be controlled by a PLC.

[0059] For the discharge component 2 to be reliable, such as Figure 6 , Figure 7 As shown, the discharge assembly 2 includes a discharge mounting plate 21, an insulating plate 22, and an electrostatic carrier 23. The bottom of the insulating plate 22 and the top of the electrostatic carrier 23 are connected to form a mounting cavity 24. The discharge mounting plate 21 is located inside the mounting cavity 24, and the electrostatic carrier 23 is connected to the mounting port 31. The discharge mounting plate 21 is provided with a discharge needle 211 or a discharge plate, which faces the conveying channel 32. The insulating plate 22 can effectively prevent electrostatic leakage, and the electrostatic carrier 23 has a high charge adsorption capacity, which allows electrostatic charge to accumulate rapidly and maintain a stable electrostatic field. The insulating plate 22 and the electrostatic carrier 23 form a closed mounting cavity 24, protecting the internal components from interference from external dust or foreign objects.

[0060] In this embodiment, the discharge needles 211 are arranged in an array on the discharge mounting plate 21; the insulating plate 22 and the electrostatic carrier 23 are connected by adhesive; an inlet wire 241 is provided on one side of the mounting cavity 24, and the inlet wire 241 is connected to the discharge needles 211 or the discharge plate; the electrostatic carrier 23 is made of acrylic plate or PTFE, and the discharge needles 211 or the discharge plate can release 0-120kV adjustable static electricity.

[0061] To ensure reliable placement of the discharge needle 211, a groove 212 is provided on the discharge mounting plate 21. The discharge needle 211 is located at the bottom of the groove 212, and the length of the discharge needle 211 is less than the depth of the groove 212. The discharge end of the discharge needle 211 faces the conveying channel 32, and the other end is connected to the bottom surface of the groove 212. The discharge needle 211 is located on the groove 212, which provides good protection for the discharge needle 211. The length of the discharge needle 211 is less than the depth of the groove 212, which also prevents the discharge needle 211 from exceeding the depth of the groove 212. The bottom surface of the discharge mounting plate 21 can directly contact the top surface of the electrostatic carrier 23, facilitating the placement of the discharge mounting plate 21.

[0062] To ensure effective electrostatic separation, the projection of the electrostatic carrier 23 onto the horizontal plane overlaps the projection of the discharge mounting plate 21 onto the horizontal plane. The area of ​​the electrostatic carrier 23 is larger than the area of ​​the discharge mounting plate 21. A larger area of ​​the electrostatic carrier 23 results in a larger area above the material where electrostatic charge is present, thus expanding the electrostatic separation range and improving separation efficiency.

[0063] To improve the electrostatic sorting effect, the mounting port 31 is located on the top surface of the conveying channel 32, and extends to both sides of the conveying channel 32. Materials are conveyed on the bottom surface of the conveying channel 32. Since the mounting port 31 is located on the top surface, it covers the largest area of ​​the material. Simultaneously, the mounting port 31 extends to both sides of the conveying channel 32, maximizing its width. All materials on the conveying channel 32 pass under the mounting port 31, thus enabling the sorting of all fibrous foreign objects in the passing materials and ensuring effective sorting.

[0064] To improve the reliability of the discharge assembly 2 installation, the discharge assembly 2 is provided with at least two limiting plates 25, which are arranged opposite to each other; the outer sides of the two limiting plates 25 are respectively abutted against the two sides of the mounting opening 31. The design of the limiting plates 25 can restrict the movement of the discharge assembly 2, ensuring reliable installation of the discharge assembly 2. In use, the outer sides of the two limiting plates 25 are abutted against the two sides of the mounting opening 31, which can restrict the movement of the discharge assembly 2 to both sides.

[0065] To further improve the reliability of the installation of the discharge assembly 2, four limiting plates 25 are provided, forming a rectangular frame structure. The sides of the four limiting plates 25 furthest from the center are respectively attached to the four sides of the mounting opening 31. The rectangular frame design of the limiting plates 25 provides higher overall structural strength. The four limiting plates 25, respectively attached to the four sides of the mounting opening 31, can completely restrict the four-way movement of the discharge assembly 2, ensuring the accuracy and reliability of the installation.

[0066] The mounting port 31 is provided with a guide plate 311, which cooperates with the limiting plate 25. The guide plate 311 and the limiting plate 25 cooperate to guide the limiting plate 25 after it extends into the mounting port 31, ensuring reliable insertion of the limiting plate 25. Simultaneously, the outer surface of the limiting plate 25 fits against the inner surface of the guide plate 311, strengthening the limiting effect of the limiting plate 25.

[0067] In this embodiment, the guide plate 311 faces the bottom surface of the conveying channel 32; the guide plate 311 is a bent plate that bends at the mounting port 31 toward the conveying channel 32.

[0068] To ensure safety during use, the inner and outer surfaces of the electromagnetic vibrating feeder 3 are coated with an antistatic PTFE coating.

[0069] In this embodiment, the peel strength of the tape on tape roll 19 is <6N / in, and the initial viscosity is high, with a holding power >24 hours.

[0070] To enhance protection, a fully enclosed protective chamber 4 is also included. The foreign object collection system 1, the discharge component 2, and the electromagnetic vibrating feeder 3 are all located inside the protective chamber 4. The top of the protective chamber 4 is provided with a main inlet 41, which is connected to the buffer chamber 35 through a pipeline. The bottom of the protective chamber 4 is provided with a main outlet (not shown in the figure), which is connected to the bottom opening of the discharge guide 37 through a pipeline. The protective chamber 4 includes at least one operable protective door 42. In this embodiment, double protective doors 42 are installed on the sides of the protective chamber 4.

[0071] The protective chamber 4 is also equipped with an electrostatic detector 6 for detecting static electricity in the space. The electrostatic detector 6 is existing technology and will not be described in detail here. In this embodiment, the electrostatic detector 6 is located directly above the discharge assembly 2 and is connected to the frame 11.

[0072] The protective chamber 4 is also equipped with a static eliminator 5, which is existing technology and will not be described in detail here. In this embodiment, the static eliminator 5 is an ion fan, and the static eliminator 5 is connected to the frame 11.

[0073] It also includes a positive pressure system (not shown in the figure) that maintains positive pressure inside the protective chamber 4. This positive pressure system is existing technology and will not be described in detail here. In this embodiment, the positive pressure system can use an external air source or an external fan with a filter. The external air source or fan introduces clean, dry air into the protective chamber 4 through the air inlet pipe 7, maintaining positive pressure inside the protective chamber 4. This prevents fibrous foreign matter from the workshop environment from entering the equipment and affecting material quality.

[0074] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
