Description

Technical Field

[0001] This utility model relates to the field of battery electrode processing technology, specifically to a battery electrode waste extrusion molding device used in the battery electrode processing process. Background Technology

[0002] During the processing of battery electrodes, the electrode raw materials need to be cut, typically requiring the removal of the foil tabs on both sides of the lithium battery electrode. Traditional processes usually involve collecting waste materials by creating negative pressure inside a collection box. However, due to the limited space in the collection box, these lightweight and loose strip-shaped waste materials easily occupy space, causing the collection box to fill up quickly. Operators must frequently clean the collection box, which not only increases their workload and reduces work efficiency but also leads to production stoppages due to frequent cleaning, further reducing process efficiency, increasing production cycles and costs. This severely restricts lithium battery technology and has become one of the most pressing problems to be solved in the lithium battery industry.

[0003] In response to the problem that battery electrode waste is lightweight and fluffy, easily taking up space and causing the collection box to fill up in a short time, an improved structural form has been proposed in the existing technology. Patent application number 202210647012.8, entitled "A Battery Electrode Waste Collection Device," provides a battery electrode waste collection device that adjusts the braking distance of the push plate by controlling the different levels of extension and retraction of multi-stage telescopic sleeves. This achieves the dual purpose of pressing and pushing materials, improving the throughput and space utilization of the collection box. While this addresses the problem to some extent that lightweight and fluffy battery waste easily takes up space and fills the collection box quickly, in engineering practice, the use of different levels of extension and retraction of multi-stage telescopic sleeves to adjust the braking distance of the push plate inevitably leads to a gradually decreasing diameter of the telescopic sleeves. This limits the total stroke of the telescopic sleeves and, due to the structural limitations of the telescopic rods themselves, results in weak rigidity, failing to provide sufficient thrust for deep compaction of the fluffy waste. Consequently, the compaction rate of the collection device is not high, affecting the overall efficiency of battery electrode waste collection.

[0004] In view of this, there is an urgent need for a battery electrode waste extrusion molding device that can effectively solve the problem that battery electrode waste is lightweight and fluffy, and easily occupies space. At the same time, it can provide sufficient pressure while maintaining sufficient rigidity, and can further compress the waste in the receiving chamber, improve the throughput and space utilization of the receiving box, ensure service life, and achieve precise intelligent and automated control.

[0005] To address the aforementioned technical problems, this utility model provides a battery electrode waste extrusion molding device. The extrusion module for waste collection effectively solves the problem that battery electrode waste is lightweight and fluffy, easily taking up space. At the same time, it can provide sufficient pressure while maintaining sufficient rigidity, enabling further compression of the waste in the collection chamber, improving the throughput and space utilization of the collection box, ensuring service life, and achieving precise intelligent and automated control.

[0006] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0007] A battery electrode waste extrusion molding device includes a telescopic assembly, an extrusion chamber, and a flip-top door. The telescopic assembly includes a fixed part and a moving part. The fixed part of the telescopic assembly is fixed to the extrusion module housing, and the moving part of the telescopic assembly penetrates the internal cavity of the extrusion chamber and is telescopically oriented relative to the extrusion chamber. The flip-top door is fixed to the end side of the extrusion chamber away from the telescopic assembly and is foldably closed with the extrusion chamber. By having the moving part of the telescopic assembly penetrate the internal cavity of the extrusion chamber and working together with the foldably closed flip-top door, the battery waste is ensured to be fully compacted inside the cavity of the extrusion chamber. This solves the problem that lightweight and fluffy battery electrode waste easily occupies space, improving the throughput and space utilization of the receiving box.

[0008] Furthermore, the telescopic assembly includes a telescopic component, a flange, a piston head, and a pressing plate. The telescopic component passes through the flange and is integrated with the piston head, and is configured to move together. The piston head is fixed to the end side of the telescopic component and is located on the other side away from the telescopic component. The pressing plate is fixed to the telescopic component through the piston head and is located at the farthest end away from the flange.

[0009] Furthermore, the telescopic assembly is telescopically connected to the piston head.

[0010] Furthermore, the telescopic assembly also includes a connecting plate that is parallel to and spaced apart from the flange and located at the other end away from the piston head. At least two guide supports are also provided between the connecting plate and the flange. One end of the guide support is fixed against the end side of the connecting plate, and the other end of the guide support is fixed against the end side of the flange.

[0011] Furthermore, the telescopic component extends along the length of the guide support after passing through the through hole in the middle of the connecting plate, and is fixed to the flange.

[0012] Furthermore, the telescopic assembly also includes a cover plate fixed between the connecting plate and the flange, the cover plate being located above the top of the guide support.

[0013] Furthermore, the flip door includes a bolt plate, a movable plate, and at least one drive rod, wherein the bolt plate is fixed to the extrusion chamber and extends in a direction away from the telescopic assembly; the movable plate is rotatably disposed on the bolt plate and is configured to be closed with the extrusion chamber; one end of the drive rod is rotatably fixed to the extrusion chamber, and the other end is drivably connected to the movable plate.

[0014] Furthermore, the extrusion module also includes at least one locking device that is releasably locked to the flip-top door, one end of which is fixed to the extrusion chamber, and the other end of which is releasably locked to the flip-top door.

[0015] Furthermore, the locking device includes a second mounting base, a second telescopic cylinder, and a insert plate, wherein the second mounting base is fixed on the extrusion chamber and is disposed against the outer side of the flip-top door; the insert plate is fixed on the second mounting base by the second telescopic cylinder and is telescopically disposed relative to the second mounting base.

[0016] Furthermore, the locking device also includes a guide plate seat disposed at the edge of the through hole of the bolt plate, the guide plate seat being disposed on the outer side of the bolt plate and extending in a direction away from the bolt plate.

[0017] The battery electrode waste extrusion molding device provided in the above embodiments integrates different functions by dividing the extrusion chamber into a first observation chamber, a discharge chamber, and a molding chamber, ensuring the operability and maintainability of the extrusion chamber. The first and second observation plates installed in the first and discharge chambers allow for timely understanding and monitoring of the real-time situation in different processes within the extrusion chamber, improving the overall flexibility, reliability, and safety of the extrusion chamber operation. A linkage structure is formed between the first telescopic cylinder, the movable plate, and the extrusion chamber, enabling the movable plate to close and open under the extension and retraction of the telescopic end. A drive connection, with one end rotatably fixed to the extrusion chamber and the other end drivably connected to the movable plate, allows the movable plate to rotate relative to the extrusion chamber under the action of the drive rod, thus switching between the closed and open states of the extrusion chamber. Locking the flip-top door ensures that the internal cavity of the extrusion chamber remains fixed during operation, allowing for continuous compaction of the added electrode waste, further improving the throughput and space utilization of the receiving box.

Furthermore, if any description involving "first," "second," "S1," "S2," "step one," "step two," etc., is involved in the embodiments of this utility model, such description is only for descriptive purposes and should not be construed as indicating or implying their relative importance, or implicitly indicating the number of technical features indicated or the execution order of the method. Those skilled in the art will understand that anything that does not violate the essential points of the utility model within the scope of its inventive concept should be included within the protection scope of this utility model.

[0033] like Figure 1 As shown in the illustration, an automatic extrusion molding machine for recycling battery electrode waste, according to a partially exemplary embodiment, includes an extrusion module 20, an extrusion module housing 10 covering the extrusion module 20, and a feeding hopper assembly 30 disposed between the extrusion module housing 10 and the extrusion module 20. One end of the feeding hopper assembly 30 is connected to the extrusion module 20, and the other end, disposed opposite to it, penetrates the extrusion module housing 10 and is fixed to the top surface of the extrusion module housing 10, thereby forming a feeding channel for material to enter the extrusion module 20. Thus, battery electrode waste generated during the battery production process can conveniently enter the extrusion module through the feeding hopper assembly, and then be compressed by the extrusion module, improving the throughput and space utilization of the receiving bin.

[0034] In this embodiment of the application, the extrusion module housing 10 can be of various suitable structures, preferably, such as Figure 2 As shown, the extrusion module housing 10 is welded from a panel and supporting ribs, thus possessing sufficient rigidity to load and withstand uncertain positional loads. Specifically, the extrusion module housing 10 includes a housing frame 11, an electrical control room door 12, and a safety door 13. The housing frame 11 is a frame structure with a receiving cavity, formed by connecting angle steel end to end. The electrical control room door 12 and the safety door 13 are lockably and rotatably connected to the housing frame 11. Thus, the extrusion module housing, formed by welding the panel and supporting ribs, provides a support platform for accommodating the extrusion module, ensuring the safety of the extrusion module operation, and also providing an operational platform for the collection, temporary storage, and transfer of battery electrode waste, providing a carrier for achieving continuous automated operation.

[0035] In a preferred embodiment of this application, a battery electrode waste extrusion molding apparatus is provided, which uses an extrusion module 20 to compress and collect the battery electrodes. Figure 3 and Figure 4As shown, the extrusion module 20 includes a telescopic assembly 21, an extrusion chamber 22, and a flip-top door 23. The telescopic assembly 21 includes a fixed part and a moving part. The fixed part of the telescopic assembly 21 is fixed to the extrusion module housing 10, and the moving part of the telescopic assembly 21 penetrates the internal cavity of the extrusion chamber 22 and is telescopically oriented relative to the extrusion chamber 22. The flip-top door 23 is fixed to the end side of the extrusion chamber 22 away from the telescopic assembly 21 and is foldably closed with the extrusion chamber 22. Thus, by having the moving part of the telescopic assembly penetrate the internal cavity of the extrusion chamber and working together with the foldably closed flip-top door of the extrusion chamber, the battery waste can be fully compacted inside the cavity of the extrusion chamber, solving the problem that lightweight and fluffy battery electrode waste easily occupies space, and improving the throughput and space utilization of the receiving box.

[0036] Specifically, the telescopic assembly 21 includes a telescopic component 210, a flange 211, a piston head 212, and a compression plate 214. The telescopic component 210 passes through the flange 211 and is integrated with the piston head 212, and they move together. The piston head 212 is fixed to the end face of the telescopic component 210, located on the side furthest from the telescopic component 210. The compression plate 214 is fixed to the telescopic component 210 via the piston head 212 and is located at the furthest end from the flange 211. Thus, the piston head positioned between the compression plate and the telescopic component ensures a sufficient force-bearing area when pressure is transferred from the telescopic component to the compression plate, thereby ensuring stability and reliability during the compression process. Through the telescopic movement of the telescopic assembly, the piston head drives the compression plate to move retractably relative to the compression chamber, thereby compressing the battery electrode waste inside the compression chamber and solving the problem that lightweight and fluffy battery electrode waste easily occupies space.

[0037] Furthermore, to ensure the reliability and stability of force transmission between the telescopic assembly 210 and the compression plate 214, the telescopic assembly 210 and the piston head 212 are telescopically connected. Specifically, the telescopic assembly 210 is telescopically connected to the piston head 212 via a pin 213, allowing it to extend and retract.

[0038] To facilitate the fixing of the telescopic assembly 210, a connecting plate 215 is also included, which is parallel to and spaced apart from the flange 211, located at the end away from the piston head 212. At least two guide supports 216 are also provided between the connecting plate 215 and the flange 211. One end of each guide support 216 is fixed against the end side of the connecting plate 215, and the opposite end is fixed against the end side of the flange 211, forming a stable frame structure together with the connecting plate 215 and the flange 211. Thus, the stable frame structure formed by the at least two guide supports 216 between the connecting plate 215 and the flange 211 provides a fixed installation space for the telescopic assembly 210. Specifically, the telescopic assembly 210 passes through the through hole in the middle of the connecting plate 215, extends along the length of the guide support 216, and is fixed to the flange 211. Optionally, the telescopic assembly 210 is an electric cylinder assembly. The cylinder body of the electric cylinder assembly is fixed to the flange 211, and the piston rod of the electric cylinder assembly passes through the flange 211 and is telescopically extendable along the length of the guide support 216. Therefore, by selecting an electric cylinder assembly as the telescopic assembly, high-precision motion control can be achieved in complex working environments. It also features low noise, energy saving, and high rigidity, effectively solving the defects of existing multi-stage telescopic sleeve structures, such as insufficient rigidity, limited stroke, and inability to provide sufficient thrust, resulting in insufficient compaction of waste materials. This significantly improves the compaction rate of the collection equipment while enabling intelligent and automated control.

[0039] To prevent damage to the telescopic assembly 21 from falling foreign objects during operation, a cover plate 217 is also included, fixed between the connecting plate 215 and the flange 211. The cover plate 217 is located above the top of the guide support 216. This ensures comprehensive protection for the telescopic assembly 210 operating between the connecting plate 215 and the flange 211, ensuring continuous and safe operation of the telescopic assembly 21.

[0040] Optionally, to facilitate control and adjustment of the gap between the piston head 212 and the extrusion plate 214, and to avoid wear caused by direct contact between the piston head 212 and the extrusion plate 214, at least one detachable slider 218 is also included on the piston head 212. The sliders 218 are spaced apart on the outer peripheral side of the piston head 212 and abut against the extrusion plate 214. Specifically, the gap between the piston head 218 and the extrusion plate 214 can be adjusted by replacing sliders 218 of different thicknesses. Preferably, the sliders 218 are made of antistatic nylon material. Thus, the use of sliders made of antistatic nylon material effectively avoids the damage to equipment operation caused by static electricity generated by the piston head during the extrusion molding process.

[0041] Optionally, to ensure that the telescopic assembly 210 can smoothly compress the piston head 212, at least two guide shafts 219 are further included between the flange 211 and the piston head 212. One end of each guide shaft 219 is fixed against the side of the flange 211, and the other end is fixed to the side of the piston head 212. Preferably, the guide shafts 219 and guide supports 216 are coaxially arranged on both sides of the flange 211. Thus, the coaxial arrangement of the guide shafts and guide supports significantly improves the rigidity of the telescopic assembly after installation and fixation, ensuring smooth pressure transmission.

[0042] In the preferred embodiment of this application, such as Figure 5 As shown, the piston head 212 includes a base 2121, a first mounting plate 2122, a second mounting plate 2123, and a support plate 2124. The base 2121 is fixed to the end side of the first mounting plate 2122, and the second mounting plate 2123 is disposed on both sides of the first mounting plate 2122. The second mounting plate 2123 is spaced apart from the first mounting plate 2122 and is fixed to the first mounting plate 2122 as a whole by the support plate 2124, and is configured to move together.

[0043] Optionally, to ensure the reliability of the connection between the guide shaft 219 and the piston head 212, at least one guide sleeve 2126 is provided on the side of the first mounting plate 2122. The guide sleeve 2126 is adapted to the guide shaft 219, thereby ensuring that the guide shaft 219 can be quickly and reliably connected to the first mounting plate 2122, thereby ensuring the overall rigidity of the telescopic assembly 21.

[0044] In summary, the telescopic assembly provided by this utility model provides a fixed installation space for the telescopic component through at least two guide supports set between the connecting plate and the flange; a piston head is set between the extrusion plate and the telescopic component to ensure the force-bearing area when the pressure is transmitted from the telescopic component to the extrusion plate, thereby ensuring the stability and reliability of the compression process; through the telescopic movement of the telescopic assembly, the piston head drives the extrusion plate to move telescopically relative to the extrusion chamber, thereby extruding the battery electrode waste inside the extrusion chamber, solving the problem that the light and fluffy battery electrode waste easily occupies space; the guide shaft and guide supports set along the coaxial axis significantly improve the rigidity of the telescopic assembly after installation and fixation, ensuring the smooth transmission of pressure; by selecting an electric cylinder assembly as the telescopic component, high-precision motion control can be achieved in complex working environments, while having the advantages of low noise, energy saving, and high rigidity, effectively solving the defects of insufficient rigidity, limited stroke, and inability to provide sufficient thrust in the existing multi-stage telescopic sleeve structure, which leads to the inability to compact the waste, and can significantly improve the compaction rate of the collection equipment while providing intelligent and automated control.

[0045] In the preferred embodiment of this application, such as Figure 6 As shown, the extrusion chamber 22 includes a support 221, a chamber body 222, and a feed inlet 223. The support 221 is a supporting beam truss structure made of U-shaped steel connected by welding, riveting, or bolting. The chamber body 222 is set on the top surface of the support 221 and fixed to the support 221. The feed inlet 223 is an opening formed on the top surface of the chamber body 222 and connected to the internal cavity of the chamber body 222.

[0046] Optionally, to facilitate real-time monitoring of the operating conditions within the extrusion chamber 22, the chamber body 222 includes a first observation chamber 2221, a discharge chamber 2222, and a forming chamber 2223. The first observation chamber 2221 is connected to the forming chamber 2223 via the discharge chamber 2222, and the inlet 223 is located on the top surface of the first observation chamber 2221. Thus, after passing through the inlet 223, the material enters the discharge chamber 2222 under the action of the telescopic assembly 21, and then enters the forming chamber 2223 for further compaction and shaping. Therefore, by dividing the extrusion chamber into a first observation chamber, a discharge chamber, and a forming chamber, different functions are integrated, ensuring the operability and maintainability of the extrusion chamber.

[0047] Optionally, to enable timely assessment of the material condition inside the extrusion chamber 22, a first observation plate 2221a is provided on the side of the first observation chamber 2221. The first observation plate 2221a is made of transparent material to facilitate direct observation of the real-time operating conditions inside the first observation chamber 2221. Further, based on the same mechanism, a second observation plate 2222a is provided on the side of the discharge chamber 2222. The observation plate 2221a is also made of transparent material. Preferably, to improve operational convenience, the first observation plate 2221a and the second observation plate 2222a are located on the same side of the extrusion chamber 22.

[0048] In summary, the extrusion chamber provided by this utility model integrates different functions by dividing the extrusion chamber into a first observation chamber, a blanking chamber, and a forming chamber, thus ensuring the operability and maintainability of the extrusion chamber. The first observation plate and the second observation plate set on the first observation chamber and the blanking chamber can be used to understand and grasp the real-time situation of different processes inside the extrusion chamber in a timely manner, thereby improving the flexibility, reliability and safety of the overall extrusion chamber operation.

[0049] In the preferred embodiment of this application, such as Figure 3 , Figure 6 , Figure 7 and Figure 8As shown, the flip door 23 includes a latch plate 231, a movable plate 232, and at least one drive rod 233. The latch plate 231 is fixed to the extrusion chamber 22 and extends in a direction away from the telescopic assembly 21. The movable plate 232 is rotatably mounted on the latch plate 231 and is configured to be closed in conjunction with the extrusion chamber 22. One end of the drive rod 233 is rotatably fixed to the extrusion chamber 21, and the other end is drivably connected to the movable plate 233. In a preferred embodiment of this invention, the drive rod 233 is rotatably fixed to the bracket 221 of the extrusion chamber 22, thereby obtaining more stable support. Thus, by having one end rotatably fixed to the extrusion chamber and the other end drivably connected to the movable plate, the movable plate can rotate relative to the extrusion chamber under the action of the drive rod, thereby achieving the switching between the closed and open states of the extrusion chamber.

[0050] Optionally, the movable plate 232 is welded from a panel and a support beam, possessing sufficient rigidity to load and withstand uncertain positional loads. Specifically, it includes at least one rotary hole 2321 and at least one lifting hole 2322 formed on the support beam. The rotary hole 2321 is located on the end side of the support beam of the movable plate 232, and the lifting hole 2322 is located on the side side of the support beam of the movable plate 232, extending along the width direction of the movable plate 232. Specifically, the rotary holes 2321 are formed in pairs on the outermost support beam in the width direction of the movable plate 232, located on the top end side of the support beam. Preferably, the lifting holes 2322 are formed in pairs on the outermost support beam in the width direction of the movable plate 232, extending along the width direction of the movable plate 232 in a direction away from the movable plate 232. Further, it also includes at least one insertion hole 2323 formed on the outermost support beam in the width direction of the movable plate 232, the insertion hole 2323 being located at the other end away from the rotary hole 2321.

[0051] Optionally, the drive rod 233 includes a fixed base 2331 and a first telescopic cylinder 2332. One end of the first telescopic cylinder 2332 is rotatably connected to the extrusion chamber 22 via the fixed base 2331, and the other end, which is opposite to it, is driven to connect to the movable plate 232. Specifically, the fixed end of the first telescopic cylinder 2332 is rotatably connected to the extrusion chamber 22 via the fixed base 2331, and the telescopic end of the first telescopic cylinder 2332 is movably connected to the lifting hole 2322 of the movable plate 232. Thus, a linkage structure is formed between the first telescopic cylinder, the movable plate, and the extrusion chamber, and the opening and closing of the movable plate and the extrusion chamber are realized under the drive of the telescopic movement of the telescopic end.

[0052] In summary, the flip door provided by this utility model forms a linkage structure between the first telescopic cylinder, the movable plate, and the extrusion chamber. Driven by the telescopic movement of the telescopic end, the movable plate and the extrusion chamber are closed and opened. Through a drive connection that is rotatably fixed to the extrusion chamber at one end and drivably connected to the movable plate at the other end, the movable plate can be rotated relative to the extrusion chamber under the action of the drive rod, thereby realizing the switching of the extrusion chamber's closed or open state.

[0053] Optionally, to further improve the compaction of battery electrode waste and increase operational efficiency, such as... Figure 6 and Figure 8 As shown, the extrusion module 20 also includes at least one locking device 24 that is releasably locked to the flip-top door 23. One end of the locking device 24 is fixed to the extrusion chamber 22, and the other end, which is opposite to it, is releasably locked to the flip-top door 23. By locking the flip-top door, the internal cavity of the extrusion chamber is kept fixed during operation, so as to continuously compact the added electrode waste, further improving the throughput and space utilization of the receiving box.

[0054] Specifically, the locking device 24 includes a second mounting base 214, a second telescopic cylinder 243, and an insert plate 244. The second mounting base 214 is fixed to the compression chamber 22 and abuts against the outer side of the flip door 23. The insert plate 244 is fixed to the second mounting base 214 via the second telescopic cylinder 243 and is telescopically detachable relative to the second mounting base 214. Driven by the second telescopic cylinder 243, the insert plate 244 can switch between a locked and an open state with the flip door 23, thereby achieving locking and releasing of the flip door 23.

[0055] Optionally, the second mounting base 241 is welded from sheet metal and has a bracket with an internal cavity. The fixed end of the second telescopic cylinder 243 is detachably fixed to the side of the second mounting base 241 away from the flip door 23. The telescopic end of the second telescopic cylinder 243 is fixed integrally with the insert plate 244 and is movable. Thus, the telescopic end of the second telescopic cylinder 243 can drive the insert plate 244 to telescopically move relative to the flip door 23, thereby locking and releasing the flip door 23. For example, by driving the insert plate 244 through the bolt plate 231 and through the insert hole 2323 opened on the movable plate 232 in the flip door 23, a stable lock is achieved between the movable plate 232 and the bolt plate 231.

[0056] Optionally, in order to ensure that the insert plate 244 can accurately and conveniently pass through the through hole on the bolt plate 231, an insert plate guide seat 242 is also provided at the edge of the through hole of the bolt plate 231. The insert plate guide seat 242 is provided on the outer side of the bolt plate 231 and extends in a direction away from the bolt plate 231.

[0057] Furthermore, regarding the selection of the telescopic cylinder in the preferred embodiment of this utility model, it can be a pneumatic cylinder, a hydraulic cylinder, or a combination thereof, or a mechanical structure that achieves the same function. The specific structural design of the telescopic cylinder should be readily conceived by those skilled in the art, and therefore will not be described in detail here.

[0058] In summary, the battery electrode waste extrusion molding device provided by this utility model integrates different functions by dividing the extrusion chamber into a first observation chamber, a material discharge chamber, and a molding chamber, ensuring the operability and maintainability of the extrusion chamber. The first and second observation plates installed in the first and material discharge chambers allow for timely monitoring of the real-time situation in different processes within the extrusion chamber, improving the overall flexibility, reliability, and safety of the extrusion chamber operation. A linkage structure is formed between the first telescopic cylinder, the movable plate, and the extrusion chamber, enabling the movable plate to close and open under the extension and retraction of the telescopic end. A drive connection, with one end rotatably fixed to the extrusion chamber and the other end drivably connected to the movable plate, allows the movable plate to rotate relative to the extrusion chamber under the action of the drive rod, thus switching between the closed and open states of the extrusion chamber. Locking the flip-top door ensures that the internal cavity of the extrusion chamber remains fixed during operation, allowing for continuous compaction of the added electrode waste, further improving the throughput and space utilization of the receiving box.

[0059] In the preferred embodiment of this application, such as Figure 1 and Figure 9 As shown, the feed hopper assembly 30 is generally an inverted cone shape, including a feed hopper body 31, an air inlet pipe 32, and a transfer box 35. The feed hopper body 31 is a cavity formed by welding a panel and supporting ribs. The air inlet pipe 32 passes through the feed hopper body 31 and is connected to the inner cavity of the feed hopper body 31. One end of the transfer box 35 is open and connected to the inner cavity of the feed hopper body 31, while the other end extends away from the feed hopper body 31.

[0060] Optionally, the feed hopper assembly 30 also includes an isolation net 33 disposed in the inner cavity of the feed hopper body 31. The isolation net 33 is disposed below the connection between the transfer box 35 and the feed hopper body 31, thereby enabling the filtering of materials entering through the transfer box.

[0061] Optionally, to facilitate observation of the real-time operating conditions inside the feed hopper assembly 30, a second observation window 34 is also included, which is disposed on the side of the feed hopper body 31 and sealed to the feed hopper body 31. Preferably, the second observation window 34 is made of a transparent material to facilitate real-time monitoring of the conditions inside the feed hopper body 31.

[0062] Optionally, in order to improve the sealing of the feed hopper, an inlet flange 36 is also included at the connection between the air inlet pipe 32 and the feed hopper 31.

[0063] In summary, the feeding hopper assembly provided by this utility model facilitates real-time monitoring of the internal conditions of the feeding hopper through a second observation window set on the side of the feeding hopper body; and the isolation net set in the inner cavity of the feeding hopper body can filter the materials entering through the transfer box.

[0064] In the preferred embodiment of this application, such as Figure 1 and Figure 10 As shown, in order to improve the operating efficiency of the waste collection device, a recycling component 40 is also provided at the end of the discharge port of the extrusion module 20. The recycling component 40 is movably locked below the end of the discharge port of the extrusion module 20. The discharge port of the extrusion module 20 protrudes from the outer side of the extrusion module housing 10 and extends toward the internal cavity of the recycling component 40.

[0065] Specifically, the recycling assembly 40 includes a recycling vehicle body 41 and at least one set of reinforcing ribs 42. The recycling vehicle body 41 is formed by welding a panel and supporting ribs to form a storage cavity with an open top. The reinforcing ribs 42 are arranged at the corners of the recycling vehicle body 41 along the vertical direction to improve the impact resistance of the recycling body 41 in the vertical direction.

[0066] Optionally, to reduce damage to the recycling components caused by the falling of extruded waste material after processing by the extrusion module, an anti-collision strip 43 is also included, which is fixedly laid on the top surface of the recycling vehicle body 41 and covers the inner edge of the top surface of the recycling vehicle body 41. By covering the inner edge of the top surface of the recycling vehicle body with an anti-collision strip, damage to the recycling vehicle body, especially the fixed surface, is effectively avoided by the falling of battery waste material after processing by the extrusion module.

[0067] Optionally, to reduce the load during transport in the battery waste recycling process, the recycling assembly 40 also includes at least one omnidirectional caster 44 disposed on the bottom end face of the recycling vehicle body 41. Preferably, the recycling assembly 40 also includes at least one fixed caster 45 disposed on the bottom end face of the recycling vehicle body 41. Thus, by providing omnidirectional casters on the bottom end face of the recycling vehicle body, the recycling assembly can move freely, thereby facilitating the transfer of processed battery waste; at the same time, the fixed casters allow the recycling vehicle body to be fixed in a preset position, thereby improving the efficiency of the battery waste recycling process.

[0068] In summary, the recycling component provided by this utility model effectively prevents damage to the recycling vehicle body, especially the fixed surface, during the recycling process after the battery waste is processed by the extrusion module by covering the inner edge of the top surface of the recycling vehicle body with anti-collision rubber strips; by setting universal casters on the bottom surface of the recycling vehicle body, the recycling component can move freely, thereby realizing convenient transfer of the processed battery waste; at the same time, the fixed casters can fix the recycling vehicle body in a preset position, thereby improving the efficiency of the battery waste recycling process.

[0069] In the preferred embodiment of this application, such as Figure 1 and Figure 11 As shown, to ensure the safety of the operation process, a baffle assembly 50 is also included, which is disposed on the top surface of the recycling assembly 40. The baffle assembly 50 covers the top of the recycling assembly 40 and is detachably connected to the recycling assembly 40. Preferably, the top surface of the baffle assembly 50 is also provided with an observation window 51 so as to monitor the utilization of the internal space of the recycling assembly 40 in real time.

[0070] In the preferred embodiment of this application, such as Figure 1 and Figure 12 As shown, in order to avoid dust diffusion during the operation, a dust removal component 60 is also included, which is connected to the feed hopper component 30 through a pipe assembly 70. One end of the pipe assembly 70 is connected to the feed hopper 30, and the other end of the pipe assembly 70 is connected to the dust removal component 60.

[0071] Specifically, such as Figure 12 As shown, the dust removal assembly 60 includes a dust removal device 61, a dust recovery device 62, and an air inlet 63. The dust recovery device 62 is movably disposed in the bottom cavity of the dust removal device 61, and the dust removal device 61 is connected to the pipe assembly 70 through the air inlet 63. The air inlet 62 is disposed on the side of the dust removal device 61 and is connected to the internal cavity of the dust removal device 61.

[0072] Furthermore, the specific structure, model, power, etc. of the dust removal device 61 should be quite mature technology for those skilled in the art and easy to conceive of, so they will not be described in detail here.

[0073] In the preferred embodiment of this application, such as Figure 1 and Figure 13 As shown, the duct assembly 70 includes an inlet flange 71, a hose 72, and an outlet flange 73, wherein the inlet flange 71 and the outlet flange 73 are respectively located on the two ends of the hose 72.

[0074] In the preferred embodiment of this utility model, such as Figure 1 and Figure 12As shown, the system also includes a monitoring system 80 for intelligent control of the entire extrusion molding machine. This monitoring system 80 is integrated with the dust removal assembly 60 and includes a wind speed sensor 81, a differential pressure transmitter 82, a temperature sensor 83, and a photoelectric position switch 84, all mounted on the side of the dust removal assembly 60. These components are electrically connected to the extrusion module 20. Preferably, the wind speed sensor 81, differential pressure transmitter 82, temperature sensor 83, and photoelectric position switch 84 are located on the same side of the dust removal device 61 as the air inlet 63.

[0075] Furthermore, the specific implementation of the monitoring system 80, as well as the structure, principle, or other structural shape for converting electrical signals into manipulation and visual scenes to achieve the same function, should be easily conceived by those skilled in the art, and therefore will not be elaborated upon here.

[0076] In addition, it includes cables and other auxiliary equipment. For example, control switches, which should be easily conceived by those skilled in the art, will not be described in detail here.

[0077] The automatic recycling extrusion molding machine for battery electrode waste provided in the above embodiments of this application has at least the following characteristics:

[0078] The automatic extrusion molding machine for recycling battery electrode waste provided in this application embodiment, by using an electric cylinder assembly as the telescopic component, can achieve high-precision motion control in complex working environments. It also features low noise, energy saving, and high rigidity, effectively solving the defects of existing technologies using multi-stage telescopic sleeve structures, such as insufficient rigidity, limited stroke, and inability to provide sufficient thrust, leading to insufficient compaction of waste materials. This significantly improves the compaction rate of the collection equipment while providing intelligent and automated control. By dividing the extrusion chamber into a first observation chamber, a discharge chamber, and a molding chamber, different functions are integrated, ensuring the operability and maintainability of the extrusion chamber. The first and second observation plates installed in the first and discharge chambers allow for timely understanding and monitoring of the real-time situation in different processes within the extrusion chamber, improving the flexibility, reliability, and safety of the overall extrusion chamber operation. The first telescopic cylinder forms a linkage structure with the movable plate and the extrusion chamber, and the telescopic movement at the telescopic end drives… The system enables the opening and closing of the movable plate and the extrusion chamber. A drive connection, with one end rotatably fixed to the extrusion chamber and the other end drivably connected to the movable plate, allows the movable plate to rotate relative to the extrusion chamber under the action of a drive rod, thus switching the extrusion chamber between closed and open states. Locking the flip-top door ensures the internal cavity of the extrusion chamber remains fixed during operation, allowing for continuous compaction of the added electrode waste, further improving the throughput and space utilization of the collection box. Anti-collision strips covering the inner edge of the top surface of the recycling vehicle effectively prevent damage to the recycling vehicle body, especially the fixed surface, during the fall of the battery waste after processing by the extrusion module. Universal casters on the bottom surface of the recycling vehicle allow the recycling components to move freely, facilitating convenient transfer of processed battery waste. Simultaneously, fixed casters allow the recycling vehicle body to be fixed in a preset position, thereby improving the efficiency of the battery waste recycling process.

[0079] The above description is merely a specific embodiment of this utility model. The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should all be considered to be within the scope of this specification.

[0080] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
