Description

Technical Field

[0001] The present invention relates to the technical field of battery production and manufacturing, and particularly to a cutting waste and fume treatment system and a battery production line. Background Art

[0002] During the production process of the positive electrode sheet and the negative electrode sheet, it is necessary to cut the electrode sheet strip to process and form a single electrode sheet with tabs. Therefore, waste and fumes will inevitably be generated during the production process of the electrode sheet. In the prior art, a separate waste treatment device and a separate fume treatment device are usually set up to collect waste and fumes respectively, resulting in a complex overall structure, a large occupied space, and inconvenient centralized treatment of waste and fumes. Summary of the Invention

[0003] In view of this, the present invention provides a cutting waste and fume treatment system and a battery production line to solve the problems that the existing cutting waste and fume treatment system has a complex overall structure, a large occupied space, and inconvenient centralized treatment of waste and fumes.

[0004] In a first aspect, the present invention provides a cutting waste and fume treatment system, including: a hood, a partition structure is arranged inside the hood to divide the interior of the hood into a waste treatment chamber and a fume treatment chamber, a negative pressure interface and a dust suction port are opened on the hood, and both the negative pressure interface and the dust suction port are communicated with the fume treatment chamber; a waste recycling device, arranged inside the hood and corresponding to the waste treatment chamber, and adapted to separate solid waste and dust; the waste recycling device has a dust discharge port, and the dust discharge port penetrates through the partition structure to communicate with the fume treatment chamber; a fume collection device, arranged inside the hood and corresponding to the fume treatment chamber.

[0005] Beneficial effects: The waste recycling device is used to collect and treat the waste generated by tab cutting. The fumes carried during the waste recycling process are transported to the fume treatment chamber through the dust discharge port, and the fume collection device centrally treats the fumes inhaled from the dust suction port and the fumes input from the dust discharge port, simplifying the overall structure, reducing the occupied space, and facilitating the centralized treatment of waste and fumes.

[0006] In an optional embodiment, the fume collection device includes a plurality of filter elements, and the plurality of filter elements are distributed in the fume treatment chamber.

[0007] Beneficial effects: The filter elements are used to filter the fumes in the fume treatment chamber, so that the fume particles remain on the surface of the filter elements.

[0008] In an optional embodiment, the fume collection device further includes a blowing assembly, and the blowing assembly is communicated with the inner cavities of the plurality of filter elements.

[0009] Beneficial effect: When too much soot covers the surface of the filter element, a positive pressure is provided to the inner cavity of the filter element through the air blowing assembly, so that the soot on the surface of the filter element drops off, realizing the cleaning of the filter element and ensuring the filtering effect.

[0010] In an alternative embodiment, the soot collection device further includes a dust collection structure, and the dust collection structure is arranged in the hood and corresponds to the lower part of several filter elements.

[0011] Beneficial effect: When the surface of the filter element is cleaned, the dust collection structure can receive the dropped soot and realize the collection of the soot.

[0012] In an alternative embodiment, the waste recycling device includes a feed pipe, a cyclone separation structure and a dust discharge pipe. One end of the feed pipe is communicated with the cyclone separation structure, the other end of the feed pipe penetrates through the hood to communicate with the outside, the dust discharge pipe is communicated with the top outlet of the cyclone separation structure, and one end of the dust discharge pipe forms the dust discharge port.

[0013] Beneficial effect: Utilizing the cyclone centrifugal force of the cyclone separation structure, the waste sucked in by the feed pipe is transported downward under the action of centrifugal force and gravity, so that the soot particles synchronously sucked in by the feed pipe move upward and enter the soot treatment chamber through the dust discharge pipe, realizing the separation of waste and soot.

[0014] In an alternative embodiment, the waste recycling device further includes a compaction assembly, and the compaction assembly is arranged corresponding to the cyclone separation structure and is adapted to compact the waste in the cyclone separation structure.

[0015] Beneficial effect: Using the compaction assembly to compact the waste, reducing the occupied space of the waste, reducing the cleaning frequency of the waste, and facilitating the centralized treatment of the waste.

[0016] In an alternative embodiment, the compaction assembly includes: a feeding structure inserted into the cyclone separation structure, and the feeding structure is adapted to transport the waste in the cyclone separation structure towards the bottom outlet of the cyclone separation structure; an elastic opening and closing structure arranged corresponding to the bottom outlet of the cyclone separation structure, and the elastic opening and closing structure has a closed position and an open position; in the closed position, under the elastic force of the elastic opening and closing structure, the elastic opening and closing structure blocks the bottom outlet of the cyclone separation structure and cooperates with the feeding structure to compact the waste; in the open position, the extrusion force of the feeding structure and the gravity of the waste overcome the elastic force of the elastic opening and closing structure, and the elastic opening and closing structure cancels the blocking of the bottom outlet of the cyclone separation structure to make the bottom outlet of the cyclone separation structure communicate with the outside.

[0017] Beneficial effects: Waste materials are conveyed to the bottom outlet of the cyclone separation structure through the feeding structure. At this time, the elastic opening and closing structure is in the closed position, and the waste materials gradually accumulate on the elastic opening and closing structure and are gradually compacted under the extrusion force of the feeding structure. When the sum of the gravity of the accumulated and compacted waste materials and the extrusion force of the feeding structure reaches a certain value, the elastic force of the elastic opening and closing structure can be overcome, and the elastic opening and closing structure moves to the open position. Under the action of gravity, the waste materials fall. At this time, even if the elastic opening and closing structure is opened, since the feeding structure is filled with waste materials, the wind force will not drop suddenly. When the extrusion force of the feeding structure on the elastic opening and closing structure and the gravity of the waste materials are not greater than the elastic force of the elastic opening and closing structure after the waste materials fall, the elastic opening and closing structure moves to the closed position under the action of the elastic force, thereby blocking the bottom outlet of the cyclone separation structure and avoiding air volume loss. Therefore, during the process of treating waste materials, the air volume in the feeding pipe and the cyclone separation structure can be ensured not to be affected, the material suction effect of the feeding pipe is guaranteed, and the collection of waste materials is not affected.

[0018] In an optional embodiment, the compaction assembly includes: a feeding structure, which is communicatively arranged with the bottom outlet of the cyclone separation structure; a collection structure, located downstream of the feeding structure, and the collection structure has a material receiving position and a material discharging position; a cutting and blocking structure, arranged corresponding to the connection between the feeding structure and the collection structure, and the cutting and blocking structure has an avoidance position and a blocking position. When the cutting and blocking structure is in the avoidance position and the collection structure is in the material receiving position, the feeding structure is connected and communicated with the collection structure. When the cutting and blocking structure is in the blocking position, the cutting and blocking structure cuts off the waste materials between the feeding structure and the collection structure and separates the feeding structure and the collection structure, and the collection structure moves to the material discharging position.

[0019] Beneficial effects: Waste materials are continuously conveyed to the collection structure through the feeding structure. After the feeding structure continuously conveys for a predetermined time, the waste materials gradually fill the collection structure and are compacted in the collection structure. The cutting and blocking structure is moved from the avoidance position to the blocking position. The cutting and blocking structure blocks the outlet of the feeding structure and cuts off the waste materials between the feeding structure and the collection structure during the movement. The collection structure moves from the material receiving position to the material discharging position for discharging materials. During the discharging process, even if the collection structure is communicated with the outside, under the blocking action of the cutting and blocking structure, the feeding structure and the cyclone separation structure located upstream are not communicated with the outside, thereby avoiding air volume loss, ensuring the material suction effect of the feeding pipe, and not affecting the collection of waste materials.

[0020] In an optional embodiment, the collecting structure and the cutting and blocking structure are connected, and the compacting assembly also includes a first driving structure, which is transmission-connected to the collecting structure and / or the cutting and blocking structure, and is suitable for driving the cutting and blocking structure to move between the avoidance position and the blocking position, and simultaneously driving the collecting structure to move between the material receiving position and the material discharging position.

[0021] Beneficial effects: The collecting structure and the cutting and blocking structure are connected, and the first driving structure can be used to simultaneously drive the collecting structure and the cutting and blocking structure to transfer positions, thereby simplifying the overall structure and operating steps and facilitating the coordinated actions of cutting, blocking and discharging.

[0022] In a second aspect, the present invention also provides a battery production line, comprising the above-mentioned cutting waste and smoke treatment system. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] The following combines Figures 1 to 12 , and describes the embodiments of the present invention.

[0040] According to an embodiment of the present invention, on the one hand, a cutting waste and soot treatment system is provided, which includes a hood 1, a waste recycling device 2, and a soot collection device 3. A partition structure 11 is provided inside the hood 1 to divide the interior of the hood 1 into a waste treatment chamber 12 and a soot treatment chamber 13. A negative pressure interface 14 and a dust suction port 15 are provided on the hood 1, and both the negative pressure interface 14 and the dust suction port 15 are communicated with the soot treatment chamber 13. The waste recycling device 2 is arranged inside the hood 1 and corresponds to the waste treatment chamber 12, and is adapted to separate solid waste and dust. The waste recycling device 2 has a dust discharge port 21, and the dust discharge port 21 penetrates through the partition structure 11 to communicate with the soot treatment chamber 13. The soot collection device 3 is arranged inside the hood 1 and corresponds to the soot treatment chamber 13.

[0041] The waste recycling device 2 is used to collect and process the waste generated by the tab cutting. The soot carried during the waste recycling process is transported into the soot treatment chamber 13 through the dust discharge port 21. The soot collection device 3 centrally processes the soot inhaled from the dust suction port 15 and the soot input from the dust discharge port 21, simplifies the overall structure, reduces the occupied space, and facilitates the centralized treatment of waste and soot.

[0042] It is worth noting that the waste recycling device 2 and the soot collection device 3 share a negative pressure interface 14. However, in the related art, the waste recycling device 2 and the soot collection device 3 are far apart (not integrally arranged), resulting in a large pressure loss, which is not conducive to the collection and treatment of waste and soot.

[0043] In one embodiment, as Figure 1 and Figure 2 shown, the soot collection device 3 includes a plurality of filter elements 31, and the plurality of filter elements 31 are distributed in the soot treatment chamber 13. The filter elements 31 are used to filter the soot in the soot treatment chamber 13, so that the soot particles remain on the surface of the filter elements 31.

[0044] It should be noted that the gas containing soot particles flows from the surface of the filter element 31 to the inner cavity of the filter element 31, so that the soot particles remain on the surface of the filter element 31, and the filtered gas is discharged through the inner cavity of the filter element 31.

[0045] It is worth noting that the number of the filter elements 31 can be specifically set according to actual needs (such as the content of soot particles in the inhaled gas and the volume of the soot treatment chamber 13).

[0046] In one embodiment, as Figure 1 and Figure 2As shown, the soot collection device 3 further includes a blowing component 32, and the blowing component 32 is communicated with the inner cavities of a plurality of filter elements 31. When too much soot covers the surface of the filter element 31, positive pressure is provided to the inner cavity of the filter element 31 through the blowing component 32, so that the soot on the surface of the filter element 31 drops off, realizing the cleaning of the filter element 31 and ensuring the filtering effect.

[0047] Specifically, as Figure 1 shown, the blowing component 32 includes a main path 321 and a plurality of branch paths 322. One ends of the plurality of branch paths 322 are all communicated with the main path 321, and the other ends of the plurality of branch paths 322 are respectively and correspondingly communicated with the inner cavities of the plurality of filter elements 31.

[0048] In one embodiment, as Figure 2 shown, the soot collection device 3 further includes a dust collection structure 33, and the dust collection structure 33 is arranged in the hood 1 and correspondingly arranged below the plurality of filter elements 31. When the surface of the filter element 31 is cleaned, the dust collection structure 33 can receive the dropped soot particles to realize the collection of soot.

[0049] It should be noted that the dust collection structure 33 can be a dust collection hopper or a dust collection box, etc. Further, rollers are arranged at the bottom of the dust collection structure 33, which is convenient for moving the dust collection structure 33 out for cleaning.

[0050] In one embodiment, as Figures 5 to 12 shown, the waste recycling device 2 includes a feed pipe 22, a cyclone separation structure 23 and a dust discharge pipe 24. One end of the feed pipe 22 is communicated with the cyclone separation structure 23, the other end of the feed pipe 22 penetrates through the hood 1 to communicate with the outside, and the dust discharge pipe 24 is communicated with the top outlet of the cyclone separation structure 23. One end of the dust discharge pipe 24 forms a dust discharge port 21. By using the cyclone centrifugal force of the cyclone separation structure 23, the waste sucked in by the feed pipe 22 is conveyed downward under the action of centrifugal force and gravity, so that the soot particles synchronously sucked in by the feed pipe 22 move upward and enter the soot treatment chamber 13 through the dust discharge pipe 24, realizing the separation of waste and soot.

[0051] In one embodiment, as Figure 5 and Figure 9 shown, the inner wall of the cyclone separation structure 23 is in a cylindrical structure, and the feeding direction of the feed pipe 22 is tangentially arranged with the inner wall of the cyclone separation structure 23. Therefore, by using the negative pressure of the feed pipe 22, a cyclone centrifugal force is formed in the cyclone separation structure 23.

[0052] It should be noted that, please refer to Figure 9 , the dust discharge pipe 24 is arranged corresponding to the central position at the upper end of the cyclone separation structure 23.

[0053] In one embodiment, as Figures 5 to 7 and Figures 9 to 11As shown, the feed pipe 22 is arranged near the top of the cyclone separation structure 23, and the dust discharge pipe 24 extends downward from the top outlet of the cyclone separation structure 23 into the cyclone separation structure 23. Therefore, there is a certain distance between the pipe orifice of the feed pipe 22 and the pipe orifice of the dust discharge pipe 24 in the vertical direction, so as to prevent the waste sucked in by the feed pipe 22 from directly contacting the dust discharge pipe 24 and causing blockage of the dust discharge pipe 24.

[0054] It should be noted that in the first embodiment, please refer to Figures 5 to 7 , the dust discharge pipe 24 includes a first pipe body 241 and a second pipe body 242. One end of the first pipe body 241 is communicated with the top outlet of the cyclone separation structure 23, the other end of the first pipe body 241 extends towards the inside of the cyclone separation structure 23, one end of the second pipe body 242 forms a dust discharge port 21, and the other end of the second pipe body 242 is communicated with the top outlet of the cyclone separation structure 23. In the second embodiment, as Figures 9 to 11 shown, the dust discharge pipe 24 is an integral pipe body. One end of the dust discharge pipe 24 forms a dust discharge port 21, and the other end of the dust discharge pipe 24 extends into the cyclone separation structure 23.

[0055] In one embodiment, as Figure 7 shown, a filtering structure is arranged at the pipe orifice of the dust discharge pipe 24. Specifically, the filtering structure is a filter net. By arranging the filtering structure, the soot particles can enter the dust discharge pipe 24, while blocking the waste from entering the dust discharge pipe 24, thereby improving the collection effect of the waste.

[0056] In one embodiment, as Figures 5 to 12 shown, the waste recycling device 2 further includes a compaction assembly 25. The compaction assembly 25 is arranged corresponding to the cyclone separation structure 23 and is adapted to compact the waste in the cyclone separation structure 23. The waste is compacted by the compaction assembly 25, reducing the occupied space of the waste, reducing the cleaning frequency of the waste, and facilitating the centralized treatment of the waste.

[0057] Specifically, in the first embodiment, as Figures 5 to 8 shown, the compaction assembly 25 includes a feeding structure 251 and an elastic opening and closing structure 252. The feeding structure 251 is inserted into the cyclone separation structure 23, and the feeding structure 251 is adapted to convey the waste in the cyclone separation structure 23 towards the bottom outlet of the cyclone separation structure 23. The elastic opening and closing structure 252 is arranged corresponding to the bottom outlet. The elastic opening and closing structure 252 has a closed position and an open position. In the closed position, under the elastic force of the elastic opening and closing structure 252, the elastic opening and closing structure 252 blocks the bottom outlet of the cyclone separation structure 23 and cooperates with the feeding structure 251 to compact the waste; in the open position, the extrusion force of the feeding structure 251 and the gravity of the waste overcome the elastic force of the elastic opening and closing structure 252, and the elastic opening and closing structure 252 cancels the blockage of the bottom outlet of the cyclone separation structure 23 to make the bottom outlet of the cyclone separation structure 23 communicate with the outside.

[0058] The waste is conveyed to the bottom outlet of the cyclone separation structure 23 through the feeding structure 251. At this time, the elastic opening and closing structure 252 is in the closed position. The waste gradually accumulates on the elastic opening and closing structure 252 and is gradually compacted under the extrusion force of the feeding structure 251. When the sum of the gravity of the accumulated and compacted waste and the extrusion force of the feeding structure 251 reaches a certain value, it can overcome the elastic force of the elastic opening and closing structure 252, and the elastic opening and closing structure 252 transfers to the open position. Under the action of gravity, the waste drops. At this time, even if the elastic opening and closing structure 252 is opened, since the feeding structure 251 is filled with waste, the wind force will not drop suddenly. When the waste drops and the extrusion force of the feeding structure 251 on the elastic opening and closing structure 252 and the gravity of the waste are not greater than the elastic force of the elastic opening and closing structure 252, under the action of the elastic force, the elastic opening and closing structure 252 transfers to the closed position, thereby blocking the bottom outlet of the cyclone separation structure 23 and avoiding air volume loss. Therefore, during the process of treating the waste, the air volume in the feed pipe 22 and the cyclone separation structure 23 can be ensured not to be affected, the material suction effect of the feed pipe 22 is ensured, and the collection of the waste is not affected.

[0059] It should be noted that the waste is continuously conveyed towards the elastic opening and closing structure 252 through the feeding structure 251. As the waste on the elastic opening and closing structure 252 increases, the waste is gradually compacted under the extrusion of the feeding structure 251. When the sum of the extrusion force of the feeding structure 251 and the gravity of the waste is greater than the elastic force of the elastic opening and closing structure 252, under the extrusion force of the feeding structure 251 and the gravity of the waste, the elastic opening and closing structure 252 is opened, so that the waste drops.

[0060] It should be further noted that when the elastic opening and closing structure 252 is in the closed position, it not only receives the waste conveyed by the feeding structure 251, but also cooperates with the feeding structure 251 to compact the waste.

[0061] It should be noted that as Figure 3 shown, a waste bin 26 can be arranged below the elastic opening and closing structure 252 to collect the waste falling from the elastic opening and closing structure 252.

[0062] In the first embodiment, as Figure 8As shown in the figure, the elastic opening and closing structure 252 includes a mounting member 2521, a blocking member 2522, and an elastic member 2523. The mounting member 2521 and the blocking member 2522 are arranged around the bottom outlet of the cyclone separation structure 23. The mounting member 2521 is fixedly connected to the cyclone separation structure 23, and the blocking member 2522 is rotatably connected to the cyclone separation structure 23. The elastic member 2523 is connected between the mounting member 2521 and the blocking member 2522 and / or between the blocking member 2522 and the cyclone separation structure 23. By rotatably arranging the blocking member 2522, under the extrusion force of the feeding structure 251 and the gravity of the waste or the elastic force of the elastic member 2523, it is convenient to drive the blocking member 2522 to rotate, so that the blocking member 2522 can be transferred between the closed position and the open position.

[0063] Of course, in other alternative embodiments, the elastic opening and closing structure 252 may only include the blocking member 2522 and the elastic member 2523. The blocking member 2522 is rotatably connected to the cyclone separation structure 23, and the elastic member 2523 is connected between the blocking member 2522 and the cyclone separation structure 23. Specifically, the elastic member 2523 may be a torsion spring, and the torsion spring is arranged at the rotation connection of the blocking member 2522 and the cyclone separation structure 23; or, the elastic member 2523 may also be a tension spring, one end of the tension spring is connected to the side of the blocking member 2522 away from the rotation connection with the cyclone separation structure 23, and the other end of the tension spring is connected to the cyclone separation structure 23.

[0064] In the first embodiment, as Figure 8 shown, a plurality of mounting members 2521 and blocking members 2522 are provided. A mounting member 2521 is arranged between two adjacent blocking members 2522. The side of the blocking member 2522 is slidably abutted against the mounting member 2521, and the elastic member 2523 is connected to two adjacent blocking members 2522. By using the mounting member 2521 and the blocking member 2522, the waste is guided and restricted during the falling process of the waste, which is convenient for waste collection.

[0065] Specifically, as Figure 8 shown, two mounting members 2521 and two blocking members 2522 are provided, and they are sequentially arranged at intervals along the circumference of the bottom outlet of the cyclone separation structure 23. In the closed position, the two blocking members 2522 jointly block the bottom outlet of the cyclone separation structure 23, and the edges of the two blocking members 2522 close to each other are butted.

[0066] Of course, in other alternative embodiments, the number of the mounting members 2521 and the blocking members 2522 can also be set to other numbers, which can be set according to actual needs, such as three, four... etc.

[0067] In the first embodiment, as Figure 8As shown, a guide groove 2524 is provided on the mounting member 2521, and a lug 2525 is provided on the side of the blocking member 2522. One end of the lug 2525 away from the blocking member 2522 passes through the guide groove 2524, and the two ends of the elastic member 2523 are respectively connected to the two lugs 2525 of the two blocking members 2522. By providing the guide groove 2524 and the lug 2525 that cooperate with each other, the rotation of the blocking member 2522 is guided, thereby improving the stability of the rotation process of the blocking member 2522 and the accuracy of the position.

[0068] It is worth noting that the guide groove 2524 is an arc-shaped groove body, and the shape of the guide groove 2524 is compatible with the moving path of the lug 2525.

[0069] Please note that Figure 8 Two guide grooves 2524 are formed on each mounting member 2521 , and the two guide grooves 2524 are respectively matched with the two lugs 2525 of the two blocking members 2522 .

[0070] In a first embodiment, if Figure 7 As shown, the feeding structure 251 includes a screw rod 2511 and a second driving structure 2512. The second driving structure 2512 is suitable for driving the screw rod 2511 to rotate. The screw rod 2511 is rotatably arranged in the cyclone separation structure 23. The screw rod 2511 extends toward the bottom outlet of the cyclone separation structure 23. During the rotation of the screw rod 2511, the waste in the cyclone separation structure 23 is transported toward the bottom outlet.

[0071] It is worth mentioning that please refer to Figure 7 The spiral rod 2511 is extended in the vertical direction, the lower end of the spiral rod 2511 corresponds to the bottom outlet of the cyclone separation structure 23, and the second driving structure 2512 is transmission-connected to the upper end of the spiral rod 2511.

[0072] It should be further explained that the waste is pressed toward the blocking member 2522 by utilizing the spiral rod 2511, and the waste is compacted on the blocking member 2522 under the combined action of the extrusion force of the spiral rod 2511 and the inner wall of the blocking member 2522. Furthermore, the blocking member 2522 is arranged opposite to the extrusion outlet of the spiral rod 2511, and the extrusion force of the spiral rod 2511 is directly applied to the inner wall of the blocking member 2522, so that the waste is compressed more densely, and the compacted waste is approximately in a block structure.

[0073] Of course, in other alternative embodiments, the feeding structure 251 may also be other structures capable of conveying waste toward the bottom outlet of the cyclone separation structure 23, such as a push plate.

[0074] It should be noted that the surface of the screw rod 2511 is coated with Teflon, which can reduce the heat generated by friction with the waste material (metal material) and meet the explosion-proof requirements.

[0075] In the first embodiment, as Figures 5 to 7 shown, a bracket is provided above the cyclone separation structure 23, and the second driving structure 2512 is arranged on the bracket. The driving end of the second driving structure 2512 penetrates through the bracket and is connected to the upper end of the screw rod 2511.

[0076] In the first embodiment, the second driving structure 2512 includes a motor.

[0077] In the first embodiment, as Figure 7 shown, the screw rod 2511 includes a rod body and spiral blades. The spiral blades are connected to the rod body. Along the feeding direction of the feeding structure 251, the pitch of the spiral blades gradually decreases. During the process of the screw rod 2511 rotating to convey the waste material to the bottom outlet, the waste material flows along the spiral direction of the spiral blades, and through the spiral blades with gradually decreasing pitch, the scattered waste material is preliminarily compacted, and the final compaction is carried out during the process of the waste material accumulating on the elastic opening and closing structure 252 to ensure the compaction effect of the waste material.

[0078] It should be noted that the feeding direction of the feeding structure 251 is the extending direction of the screw rod 2511, that is, Figure 7 the vertical direction shown.

[0079] It should be noted that in the first embodiment, the waste material is made of metal. During the process of conveying the waste material through the spiral blades with gradually decreasing pitch, only the scattered waste material can be preliminarily compacted, and it cannot be completely compacted to avoid the situation of jamming the screw rod 2511. Therefore, by setting the elastic opening and closing structure 252, under the cooperation of the screw rod 2511 and the blocking member 2522, the compaction requirement of the waste material is met without affecting the normal operation of the screw rod 2511.

[0080] Specifically, in the second embodiment, as Figures 9 to 12As shown, the compaction assembly 25 includes a feeding structure 251, a collection structure 253, and a cutting and blocking structure 254. The feeding structure 251 is communicatively connected to the bottom outlet of the cyclone separation structure 23. The collection structure 253 is located downstream of the feeding structure 251 and has a material receiving position and a discharging position. The cutting and blocking structure 254 is disposed corresponding to the connection between the feeding structure 251 and the collection structure 253 and has an avoidance position and a blocking position. When the cutting and blocking structure 254 is in the avoidance position and the collection structure 253 is in the material receiving position, the feeding structure 251 is connected to the collection structure 253; when the cutting and blocking structure 254 is in the blocking position, the cutting and blocking structure 254 cuts off the waste between the feeding structure 251 and the collection structure 253 and separates the feeding structure 251 and the collection structure 253, and the collection structure 253 moves to the discharging position.

[0081] The waste is continuously conveyed to the collection structure 253 through the feeding structure 251. After the feeding structure 251 continuously conveys for a predetermined time, the waste gradually fills the collection structure 253 and is compacted therein; the cutting and blocking structure 254 is moved from the avoidance position to the blocking position, the outlet of the feeding structure 251 is blocked by the cutting and blocking structure 254, and the waste between the feeding structure 251 and the collection structure 253 is cut off during the movement, and the collection structure 253 moves from the material receiving position to the discharging position for discharging; during the discharging process, even if the collection structure 253 is in communication with the outside, under the blocking effect of the cutting and blocking structure 254, the feeding structure 251 located upstream and the cyclone separation structure 23 will not be in communication with the outside, thereby avoiding air volume loss, ensuring the material suction effect of the feed pipe 22, and avoiding affecting the collection of waste.

[0082] It should be noted that the waste is continuously conveyed towards the collection structure 253 through the feeding structure 251. As the waste in the collection structure 253 increases, the waste is gradually compacted in the collection structure 253; a preset feeding time is set for the feeding structure 251. When the predetermined time is reached, it is considered that the waste in the collection structure 253 has reached the compaction effect. At this time, the cutting and blocking structure 254 is transferred from the avoidance position to the blocking position, and the collection structure 253 is transferred from the material receiving position to the discharging position.

[0083] It should be further noted that when the collection structure 253 is in the material receiving position, it not only receives the waste conveyed by the feeding structure 251 but also compacts the waste.

[0084] In the second embodiment, as Figures 10 to 12As shown, the collection structure 253 and the cutting and blocking structure 254 are connected and arranged. The compaction assembly 25 further includes a first driving structure 255. The first driving structure 255 is in transmission connection with the collection structure 253 and / or the cutting and blocking structure 254, and is adapted to drive the cutting and blocking structure 254 to transfer between the avoidance position and the blocking position, and at the same time drive the collection structure 253 to transfer between the material receiving position and the material discharging position.

[0085] By connecting the collection structure 253 and the cutting and blocking structure 254, the first driving structure 255 can be used to drive the collection structure 253 and the cutting and blocking structure 254 to transfer positions simultaneously, which simplifies the overall structure and operation steps and facilitates the coordinated actions of cutting, blocking and discharging.

[0086] Of course, in other alternative embodiments, the collection structure 253 and the cutting and blocking structure 254 may not be connected, and driving structures may be respectively provided for the collection structure 253 and the cutting and blocking structure 254 to drive the collection structure 253 and the cutting and blocking structure 254 respectively. Further, the moving directions of the collection structure 253 and the cutting and blocking structure 254 may be the same or opposite.

[0087] In addition, in other alternative embodiments, the collection structure 253 and the cutting and blocking structure 254 may not be connected. A driving structure is provided for the cutting and blocking structure 254 to enable the cutting and blocking structure 254 to transfer between the avoidance position and the blocking position. The collection structure 253 includes an opening and closing door structure. When the collection structure 253 is in the material receiving position, the opening and closing door structure is closed to receive and compact the waste material. When the collection structure 253 is in the material discharging position, the opening and closing door structure is opened to discharge the compacted waste material. Further, the opening and closing door structure can be opened and closed by rotation or sliding, and a driving structure for driving its opening and closing can be provided for the opening and closing door structure.

[0088] In the second embodiment, as Figure 10 and Figure 11 shown, the collection structure 253 includes a receiving portion 2531. One side surface of the receiving portion 2531 has an opening, and the opening is arranged facing the feeding structure 251. When the collection structure 253 is in the material receiving position, the outlet of the feeding structure 251 is correspondingly communicated with the opening, and the cutting and blocking structure 254 is far away from the outlet of the feeding structure 251. When the collection structure 253 is in the material discharging position, the cutting and blocking structure 254 closes the outlet of the feeding structure 251, and the receiving portion 2531 moves away from the feeding structure 251 to communicate the opening with the outside. By providing an opening on the receiving portion 2531, it is convenient to collect waste material through the opening and discharge the compacted waste material in the receiving portion 2531 through the opening.

[0089] In the second embodiment, as Figure 10 and Figure 11As shown, the accommodating part 2531 is movably arranged in the vertical direction. When the accommodating part 2531 is transferred from the material receiving position to the material discharging position in the vertical direction, the opening of the accommodating part 2531 is gradually exposed, so that the waste is removed from the opening.

[0090] Of course, in other alternative embodiments, the accommodating part 2531 can be rotatably arranged, and through the rotation of the accommodating part 2531, the accommodating part 2531 is transferred between the material receiving position and the material discharging position.

[0091] In the second embodiment, as Figures 9 to 12 shown, the collecting structure 253 further includes a housing 2532. The housing 2532 is connected to the downstream of the feeding structure 251. The housing 2532 is provided with a communication port, and the communication port is correspondingly arranged with the outlet of the feeding structure 251. When the collecting structure 253 is in the material receiving position, the accommodating part 2531 is located inside the housing 2532, and the outlet of the feeding structure 251, the communication port and the opening are correspondingly communicated. The cutting blocking structure 254 moves outwards towards the outside of the housing 2532. When the collecting structure 253 is in the material discharging position, the accommodating part 2531 moves outwards towards the outside of the housing 2532, and the opening is communicated with the outside. The cutting blocking structure 254 is inserted into the housing 2532 and blocks the communication port. By providing the housing 2532, it is convenient to arrange the cutting blocking structure 254 and the accommodating part 2531 inside the housing 2532, and the movement of the cutting blocking structure 254 and the accommodating part 2531 can be limited and guided.

[0092] It should be noted that when the accommodating part 2531 is transferred from the material receiving position to the material discharging position in the vertical direction, the opening of the accommodating part 2531 is gradually separated from the coverage of the housing 2532 and exposed, so as to be communicated with the outside for discharging materials.

[0093] In the second embodiment, as Figure 10 and Figure 11 shown, when the collecting structure 253 is in the material discharging position, the accommodating part 2531 moves downwards out of the housing 2532, and one end of the bottom of the accommodating part 2531 close to the opening is inclined downwards. When the accommodating part 2531 moves downwards out of the housing 2532, the opening is communicated with the outside. Under the action of the self-gravity of the waste, the waste slides out along the inclined bottom, which is convenient for discharging materials.

[0094] It should be noted that please refer to Figure 10 and Figure 11 , the left side surface of the accommodating part 2531 is an opening, and the bottom of the accommodating part 2531 is inclined towards the lower left.

[0095] In the second embodiment, as Figures 10 to 12As shown, the accommodating portion 2531 and the cutting and blocking structure 254 are connected, and the first driving structure 255 is drivingly connected to the cutting and blocking structure 254. Therefore, driven by the first driving structure 255, the accommodating portion 2531 and the cutting and blocking structure 254 move upward or downward together. Specifically, for the cutting and blocking structure 254, the avoiding position is above the blocking position; for the accommodating portion 2531, the receiving position is above the discharging position.

[0096] Of course, in other alternative embodiments, for the cutting and blocking structure 254, the avoiding position can be set below the blocking position; for the accommodating portion 2531, the receiving position can be set below the discharging position.

[0097] In the second embodiment, as Figures 9 to 12 shown, the cutting and blocking structure 254 includes a blocking plate 2541 and a cutter 2542. The blocking plate 2541 is used to separate the feeding structure 251 and the collecting structure 253, and the cutter 2542 is disposed on one side of the blocking plate 2541 from the avoiding position towards the blocking position. The blocking plate 2541 and the cutter 2542 are integrally arranged. During the movement of the blocking plate 2541, the cutter 2542 is driven to move simultaneously to cut the waste material. When the cutting is completed, the blocking plate 2541 moves into place to block between the feeding structure 251 and the collecting structure 253. The structure of the cutting and blocking structure 254 is simple and convenient to use.

[0098] It should be noted that the blocking plate 2541 and the cutter 2542 can be integrally formed, that is, the cutter 2542 is directly formed at the side of the blocking plate 2541. Of course, the cutter 2542 can also be separately connected to the side of the blocking plate 2541.

[0099] It should be noted that in this embodiment, as Figure 10 and Figure 11 shown, the blocking plate 2541 moves downward from the avoiding position above to the blocking position below, so the cutter 2542 is located on the lower side of the blocking plate 2541.

[0100] Of course, in other alternative embodiments, the blocking plate 2541 can move upward from the avoiding position below to the blocking position above, and at this time the cutter 2542 is located on the upper side of the blocking plate 2541.

[0101] In the second embodiment, as Figures 10 to 12 shown, the upper side of the accommodating portion 2531 is connected to the side surface of the blocking plate 2541.

[0102] In the second embodiment, as Figures 10 to 12As shown, the cutting blocking structure 254 further includes a connecting plate 2543, which is connected to a side of the blocking plate 2541 away from the cutter 2542, and the connecting plate 2543 is connected to the driving end of the first driving structure 255. Specifically, in this embodiment, the connecting plate 2543 is connected to the upper end of the blocking plate 2541, and the first driving structure 255 is a cylinder.

[0103] In a second embodiment, if Figure 10 and Figure 11 As shown, the feeding structure 251 includes an outer cylinder 2513, a screw rod 2511 and a third driving structure 2514. The third driving structure 2514 is suitable for driving the screw rod 2511 to rotate. The screw rod 2511 is rotatably arranged in the outer cylinder 2513. The outer cylinder 2513 is correspondingly connected to the bottom outlet of the cyclone separation structure 23. The screw rod 2511 is arranged corresponding to the bottom outlet of the cyclone separation structure 23, and the screw rod 2511 is extended toward the collection structure 253. The cyclone separation structure 23 conveys the waste to the screw rod 2511. During the rotation of the screw rod 2511, the waste is conveyed toward the collection structure 253.

[0104] It is worth mentioning that please refer to Figure 10 and Figure 11 The spiral rod 2511 is extended in the horizontal direction, and the outer cylinder 2513 is also extended in the horizontal direction. The right end of the outer cylinder 2513 forms the outlet of the feeding structure 251, and the collecting structure 253 is arranged corresponding to the right end of the outer cylinder 2513.

[0105] It should be further explained that the waste is pressed into the receiving portion 2531 by the spiral rod 2511, and the waste is compacted in the receiving portion 2531 under the combined effect of the squeezing force of the spiral rod 2511 and the inner wall of the receiving portion 2531. Furthermore, the receiving portion 2531 is arranged directly opposite to the squeezing outlet of the spiral rod 2511, and the squeezing force of the spiral rod 2511 is directly applied to the inner wall of the receiving portion 2531, so that the waste is compacted more compactly, and the compacted waste is approximately in a block structure. For this compact block structure, during the cutting process of the cutter 2542, even if the receiving portion 2531 moves synchronously toward the discharge position, the waste in the receiving portion 2531 will not become loose.

[0106] Of course, in other alternative embodiments, the feeding structure 251 may also be other structures capable of conveying waste toward the collecting structure 253, such as a push plate.

[0107] It is worth noting that the surface of the spiral rod 2511 is coated with Teflon, which can reduce the heat generated by friction with the waste material (metal material) and meet the explosion-proof requirements.

[0108] It should be noted that in this embodiment, the waste is made of metal rather than plastic. In order to ensure that the waste can smoothly enter the collection structure 253 from the feeding structure 251, the outlet of the outer cylinder 2513, the connecting port on the outer shell 2532 and the opening of the accommodating portion 2531 all maintain a large opening area to avoid blockage.

[0109] It is worth noting that the waste is smoothly cut off under the shearing force provided to the waste by the cutter 2542 and the right end of the outer cylinder 2513.

[0110] In a second embodiment, the third drive structure 2514 includes a motor.

[0111] In a second embodiment, if Figure 10 and Figure 11 As shown, the screw rod 2511 includes a rod body and a spiral blade, the spiral blade is connected to the rod body, and the pitch of the spiral blade gradually decreases along the feeding direction of the feeding structure 251. In the process of the screw rod 2511 rotating to transport the waste to the collection structure 253, the waste flows along the spiral direction of the spiral blade, and the spiral blade with a gradually decreasing pitch performs preliminary compaction on the scattered waste, and the final compaction is performed when the waste fills the collection structure 253, thereby ensuring the compaction effect of the waste.

[0112] It is worth noting that the feeding direction of the feeding structure 251 is the extending direction of the screw rod 2511, that is, Figure 10 and Figure 11 Horizontal direction shown.

[0113] It should be noted that, driven by the first driving structure 255, the time required for the cutting and blocking structure 254 to transfer between the avoidance position and the blocking position and the collection structure 253 to transfer between the material receiving position and the material discharging position is very short, generally only 2s to 3s. Therefore, the process of the cutting and blocking structure 254 being in the blocking position will not affect the conveying of the waste by the feeding structure 251, and thus will not cause the feeding structure 251 to be blocked. Furthermore, when the cutting and blocking structure 254 is in the blocking position, under the action of the spiral rod 2511, the waste is squeezed on the blocking plate 2541, so that the pre-compression of the waste can be achieved. When the cutting and blocking structure 254 is transferred to the avoidance position and the accommodating portion 2531 is transferred to the material receiving position, even if the waste is not in contact with the inner wall of the accommodating portion 2531, the waste will not be loose.

[0114] It should be further explained that, because the time required for the transfer of the cutting blocking structure 254 between the avoidance position and the blocking position and the transfer of the collecting structure 253 between the material receiving position and the material discharging position is very short, and the feeding structure 251 is filled with waste materials, the air volume loss during the transfer process is very small.

[0115] It should be noted that, in this embodiment, the waste material is made of metal. During the process of conveying the waste material by the spiral blade with a gradually decreasing pitch, only the scattered waste material can be preliminarily compacted, rather than being completely compacted, so as to avoid the situation of jamming the screw rod 2511. Therefore, by providing the accommodating part 2531, under the cooperation of the screw rod 2511 and the accommodating part 2531, the compaction requirement of the waste material can be met without affecting the normal operation of the screw rod 2511.

[0116] When using the cutting waste and fume treatment system of this embodiment, negative pressure is provided to the negative pressure interface 14 and the feed pipe 22, so that the fume enters the fume treatment chamber 13 through the dust suction port 15, and the waste material (carrying fume particles) enters the cyclone separation structure 23 through the feed port; through the separation of the cyclone separation structure 23, the waste material moves towards the bottom outlet of the cyclone separation structure 23, and after being compacted by the compaction assembly 25, it is collected in the waste bin 26, and the fume particles move towards the top outlet of the cyclone separation structure 23 and are conveyed to the fume treatment chamber 13 through the dust exhaust pipe 24; the fume inhaled from the dust suction port 15 and the fume conveyed by the dust exhaust pipe 24 are filtered by the filter element 31 in the fume treatment chamber 13, so that the fume particles remain on the surface of the filter element 31.

[0117] According to an embodiment of the present invention, on the other hand, a battery production line is also provided, including the above-mentioned cutting waste and fume treatment system.

[0118] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
