TECHNICAL FIELD

[0001] The application relates to the technical field of slitting, in particular to a flow regulator, an alcohol dripping device and a slitting equipment. BACKGROUND

[0002] In the lithium battery manufacturing industry, coated and dried pole pieces need to be slitted into different width film rolls according to process requirements, and a slitting tool, i.e., a slitting knife, is used for slitting. The slitting quality directly relates to the safety and performance of the battery, and one of the key factors affecting the slitting quality is the cleaning, cooling and static electricity removal of the slitting knife. The current device for cleaning, cooling and static electricity removal of the slitting knife is an alcohol dripping device. The alcohol dripping device uses the self-weight of alcohol as power to control the alcohol dripping onto the felt of the slitting knife in a time-on and time-off manner.

[0003] However, the current alcohol dripping device cannot accurately control the alcohol dripping amount of the slitting knife, and thus cannot guarantee the quality and consistency of the slitting products. SUMMARY

[0013] When the magnetic attraction rolling member is located at the first end of the sealed cavity, the opening degree of the flow regulator is maximum, and when the magnetic attraction rolling member is located at the second end of the sealed cavity, the opening degree of the flow regulator is minimum.

[0014] In one embodiment, the cavity wall of the sealed cavity is provided with a flow guide groove, the length direction of the flow guide groove is consistent with the length direction of the flow regulator, and the length direction of the flow guide groove is communicated with the first end and the second end respectively, and the cross-sectional area of the flow guide groove gradually decreases from the first end to the second end.

[0019] In one embodiment, the sealing part comprises a first sealing member and a second sealing member, the first sealing member and the second sealing member are connected in a covering manner along the thickness direction of the flow regulator, and the first sealing member and the second sealing member enclose the sealed cavity.

[0020] The cavity wall of the sealed cavity is further provided with a first rolling groove and a second rolling groove, the first rolling groove is arranged on the first sealing member, the second rolling groove is arranged on the second sealing member, and the first rolling groove and the second rolling groove are arranged in a facing manner along the thickness direction of the flow regulator.

[0021] The magnetic rolling member comprises a rolling protrusion, and the rolling protrusion is closely engaged with the first rolling groove and the second rolling groove.

[0022] In one embodiment, the push slide is made of rubber material.

[0023] In one embodiment, the two infusion catheters are located between the first seal and the second seal and are tightly clamped by the first seal and the second seal, and the two ends of the two infusion catheters communicating with the sealed cavity are clamped and fixed with the first seal and the second seal.

[0024] In one embodiment, the shell comprises a first cover and a second cover, the first cover covers one side of the first seal away from the second seal, and the second cover covers one side of the second seal away from the first seal, and the first cover and the second cover are tightly connected and tightly clamp the first seal, the second seal and the two infusion catheters.

[0025] In a second aspect, the embodiments of the present application provide an alcohol infusion device. The alcohol infusion device comprises a storage container, a solenoid valve, a plurality of hoses and the flow regulator, the storage container, the solenoid valve and the flow regulator are connected in sequence through the hoses, the two infusion catheters of the flow regulator are in communication with the two hoses respectively, the storage container contains alcohol, the alcohol is subjected to the action of gravity and flows from the storage container through the hoses in sequence to the solenoid valve and the flow regulator, and the solenoid valve controls the on-off of the alcohol in the hoses.

[0026] When the magnetic attraction rolling member is located at the first end of the sealed cavity, the alcohol infusion amount through the flow regulator is the largest, and when the magnetic attraction rolling member is located at the second end of the sealed cavity, the alcohol infusion amount through the flow regulator is the smallest.

[0027] In one embodiment, the alcohol infusion device further comprises a flow divider, which divides the alcohol into a plurality of flow paths.

[0028] The number of flow regulators is multiple, and each flow regulator is arranged on one flow path.

[0029] In one embodiment, the alcohol infusion device further comprises a dropper, and the dropper is connected with the flow divider and the flow regulator through the hoses; the dropper is made of transparent material.

[0030] In a third aspect, the embodiments of the present application provide a slitting device. The slitting device comprises a device body, a slitting knife and the alcohol dripping device, the solenoid valve, the storage container and the slitting knife of the alcohol dripping device are all mounted on the device body, the slitting knife is located below the alcohol dripping device, and two knife surfaces in the thickness direction of the slitting knife are respectively provided with a wool felt, and the two wool felts can move relative to the knife surface of the slitting knife.

[0031] The opening degree of the flow regulator is adjusted to make the alcohol drip on the wool felt in different dripping amounts.

[0032] In an embodiment, the solenoid valve is always open when the slitting device is running, and the solenoid valve is closed when the solenoid valve encounters a shutdown or the solenoid valve is abnormally running.

[0033] In an embodiment, the number of flow regulators and the number of slitting knives are both multiple, and each slitting knife corresponds to a flow regulator.

[0034] In the related art, the device for cleaning, cooling and removing static electricity of the slitting knife is an alcohol dripping device. In the alcohol dripping device, alcohol flows out from an alcohol barrel by gravity, and then flows through a solenoid valve, a flow divider, a throttle valve and a dripping pot in sequence through a hose, and finally drips on the wool felt on the slitting machine knife below the dripping pot. However, the existing alcohol dripping device cannot accurately control the alcohol dripping amount on the slitting knife, so it cannot guarantee the quality and consistency of the slitting products.

[0035] In this embodiment, the alcohol dispensing device incorporates a flow regulator between the dripper and the felt. The flow regulator achieves synchronous linkage between the magnetic pusher and the magnetic rolling element to adjust the alcohol dispensing volume. Specifically, based on the required alcohol dispensing volume, the magnetic pusher is pushed up and down to slide on the housing, causing the magnetic rolling element within the sealing section to occupy different positions within the sealing cavity. This precisely controls the opening of the flow regulator, thus precisely adjusting the amount of alcohol dispensed onto the felt on the slitting blade per unit time. This ensures the alcohol is dispensed evenly and slowly, preventing excessive alcohol dispensing that could saturate the felt and cause it to drip onto the electrode, leading to electrode demolding. It also prevents a large amount of residual alcohol on the slitting blade from adhering to metal shavings from the slitting foil, which cannot be removed by the negative pressure suction, resulting in metal shavings accumulation and viscous electrode entanglement in the battery cell, posing a product safety risk. This improves the stability and safety of the alcohol dispensing device during operation. Simultaneously, it avoids insufficient alcohol dispensing that could cause the slitting blade to overheat, shorten its lifespan, and reduce the quality of the slitting electrode end face. In this embodiment, the flow regulator can precisely control the amount of alcohol dripped, and the alcohol can be dripped evenly and slowly into the wool felt through the flow regulator. This ensures that the slitting blade always has a uniform and appropriate amount of alcohol for cleaning, cooling and removing static electricity during operation, which improves the cleaning, cooling and static electricity removal effect of the slitting blade, thereby ensuring the quality and consistency of the slitting products after being slitted by the slitting blade.

And the "same", "equal" or "parallel" used in the following text allows a certain tolerance to exist.

[0060] It should be noted that the terms "first", "second" and the like are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" and the like can explicitly or implicitly include at least one of the features.

[0061] Please refer to Figure 1 , Figure 1 The structural schematic diagram of part of the structure of the slitting device provided by the embodiment of the application is shown in the figure.

[0062] The slitting device 1000 includes a device body 300, an alcohol dripping device 100 and a plurality of slitting knives 402. The alcohol dripping device 100 and the slitting knives 402 are both mounted on the device body 300. The slitting knives are located below the alcohol dripping device 100, and the alcohol dripping device 100 is used to drip alcohol 201 to the slitting knives 402.

[0063] In the embodiment, two wool felts 401 are arranged on the thickness direction of the two knife surfaces of the slitting knives 402, i.e. the slitting knives 402 are clamped between the two wool felts 401. With the rotation of the slitting knives 402, the two wool felts 401 can move relative to the knife surface of the slitting knives 402, and the two wool felts 401 are arranged in a wool felt box (not shown in the figure). The wool felt box is located above the slitting knives 402 and is mounted on the device body 300. By dripping alcohol 201 to the position between the two wool felts 401, the slitting knives 402 are protected and cleaned, thereby ensuring the slitting quality of the slitting knives 402. The number of the slitting knives 402 is three.

[0064] The alcohol dripping device 100 comprises a storage container 20, a solenoid valve 30, a flow divider 40, a throttle valve 50, a drip pot 60, a flow regulator 10 and a plurality of hoses 70. The storage container 20 and the solenoid valve 30 are mounted on the device body 300. The storage container 20, the solenoid valve 30, the flow divider 40, the throttle valve 50, the drip pot 60 and the flow regulator 10 are sequentially connected by the hoses 70. The storage container 20 is filled with alcohol 201. The alcohol 201 is subjected to the action of gravity and flows from the storage container 20 through the hoses 70, the solenoid valve 30, the flow divider 40, the throttle valve 50, the drip pot 60 and the flow regulator 10 in sequence, and finally drips onto the wool felt 401 under the slitting knife 402 to clean, cool and remove static electricity from the slitting knife 402. The solenoid valve 30 is a switch for controlling the flow of alcohol 201 in the hose 70 between the storage container 20 and the flow divider 40. The flow divider 40 is used to flow the alcohol 201 to different flow paths through different hoses 70, and each flow path corresponds to a slitting knife 402. The number of throttle valves 50, drip pots 60 and flow regulators 10 is the same as the number of slitting knives 402. That is, one throttle valve 50, one drip pot 60 and one flow regulator 10 correspond to one flow path. The throttle valve 50 is fixed on the device body 300 and is used to control the on-off of the alcohol 201 in the hose 70 between the drip pot 60 and the flow divider 40. The drip pot 60 is hung below the throttle valve 50 through the hose 70. The flow regulator 10 is located between the drip pot 60 and the slitting knife 402 and is used to accurately control the amount of alcohol 201 dripping onto the wool felt 401 of the slitting knife 402. In this embodiment, corresponding to three slitting knives 402, the flow divider 40 divides three flow paths, i.e. the number of throttle valves 50, drip pots 60 and flow regulators 10 is three. The three drip pots 60 are all made of transparent material.

[0065] Please refer to Figure 2 , Figure 3 and Figure 4 , Figure 2 for the structure of the flow regulator of the alcohol dripping device shown in Figure 1 , Figure 3 for the exploded structure of the flow regulator shown in Figure 2 , Figure 4 for the exploded structure of the flow regulator shown in Figure 3 from another angle.

[0066] For ease of description, the thickness direction of the flow regulator 10 is defined as the Z-axis direction, the length direction is defined as the Y-axis direction, and the width direction is defined as the X-axis direction. Among them, the X-axis direction, the Y-axis direction and the Z-axis direction are perpendicular to each other.

[0067] The flow regulator 10 comprises a housing 101, a sealing part 102, a regulating part 103, and two infusion catheters 7. The sealing part 102 has a sealing cavity M. A part of the regulating part 103 is located in the sealing cavity M of the sealing part 102 and is assembled in the housing 101 together with the sealing part 102. The part of the regulating part 103 is tightly connected with the cavity wall of the sealing cavity M and can roll in the sealing cavity M. Another part of the regulating part 103 is located outside the housing 101 and is assembled on the side of the housing 101 away from the sealing part 102 in the thickness direction of the housing 101. The part of the regulating part 103 is slidingly connected with the housing 101.

[0068] In the embodiment, the housing 101 comprises a first cover 1 and a second cover 2. The sealing part 102 comprises a first sealing member 3 and a second sealing member 4. The regulating part 103 comprises a magnetic rolling member 5 and a magnetic pusher 6. The first sealing member 3 and the second sealing member 4 are connected in a covering manner along the thickness direction (i.e. the Z-axis direction) of the flow regulator 10. The first sealing member 3 and the second sealing member 4 enclose the sealing cavity M. The magnetic rolling member 5 is assembled in the sealing cavity M enclosed by the first sealing member 3 and the second sealing member 4 and is tightly connected with the first sealing member 3 and the second sealing member 4. Along the length direction (i.e. the Y-axis direction) of the flow regulator 10, the magnetic rolling member 5 can roll in the sealing cavity M relative to the first sealing member 3 and the second sealing member 4. The first cover 1 is arranged on the side of the first sealing member 3 away from the second sealing member 4, and the second cover 2 is arranged on the side of the second sealing member 4 away from the first sealing member 3. The first cover 1 and the second cover 2 are tightly connected by a plurality of fixing members 8, so that the first cover 1 and the second cover 2 tightly clamp the first sealing member 3 and the second sealing member 4, the first sealing member 3 and the second sealing member 4 are tightly connected, and the leakage of the alcohol 201 passing through the flow regulator 10 from the gap between the first sealing member 3 and the second sealing member 4 is prevented. The magnetic pusher 6 is arranged on the side of the second cover 2 away from the first cover 1, and the magnetic pusher 6 can slide relative to the second cover 2 along the length direction of the flow regulator 10. In the present disclosure, the tightly connection refers to the sealing and the gap-free passage of the alcohol 201, and the tightly clamping refers to the sealing and the gap-free passage of the alcohol 201.

[0069] In the embodiment, the magnetic rolling member 5 has magnetism and can generate a magnetic force with the magnetic pusher 6. When the magnetic pusher 6 is pushed to slide relative to the second cover 2 along the length direction of the flow regulator 10, under the interaction of the magnetic force, the magnetic pusher 6 can drive the magnetic rolling member 5 to roll in the sealing cavity M along the length direction of the flow regulator 10. It can be understood that the position of the magnetic rolling member 5 in the sealing cavity M can be adjusted by adjusting the position of the magnetic pusher 6 of the flow regulator 10.

[0070] In this embodiment, two infusion tubing 7 are located at opposite ends of the flow regulator 10 along its length. The two tubing 7 are connected to the sealing cavity M and extend through the sealing part 102 and the housing 101. The end of each infusion tubing 7 furthest from the flow regulator 10 along its length is connected to the flexible tubing 70. One infusion tubing 7 is used to allow alcohol 201 from the drip chamber 60 to flow into the sealing cavity M, and the other infusion tubing 7 is used to allow alcohol 201 from the sealing cavity M to flow out of the flow regulator 10.

[0071] It is understood that a portion of each infusion tubing 7 is located between the first seal 3 and the second seal 4, and is tightly clamped by the first seal 3 and the second seal 4; another portion is located between the first cap 1 and the second cap 2, and is also tightly clamped by the first cap 1 and the second cap 2. This not only secures the infusion tubing 7, but also prevents alcohol 201 passing through the flow regulator 10 from leaking from the gap between the infusion tubing 7 and the housing 101 and the sealing portion 102. Furthermore, a portion of each infusion tubing 7 is located outside the flow regulator 10 and is used to connect to the tubing 70.

[0072] like Figure 3 and 4 As shown, the infusion tubing 7 includes a main body section 71 and a fixing section 72. The main body section 71 and the fixing section 72 are connected sequentially along the length of the infusion tubing 7. The fixing section 72 is coaxially arranged and communicates with the main body section 71. In this embodiment, the infusion tubing 7 is used to supply alcohol 201. Both the main body section 71 and the fixing section 72 are circular tubes. The end of the main body section 71 away from the fixing section 72 is used to communicate with the flexible tube 70. The outer diameter of the fixing section 72 is larger than the outer diameter of the main body section 71, that is, along the radial direction of the infusion tubing 7, the outer surface of the fixing section 72 protrudes from the outer surface of the main body section 71. The fixing section 72 is used to snap and fix the infusion tubing 7 onto the first sealing member 3 and the second sealing member 4, preventing the infusion tubing 7 from falling off the first sealing member 3 and the second sealing member 4, thus affecting the flow of alcohol 201.

[0073] In this embodiment, there are two infusion tubing 7s, and the two infusion tubing 7s have roughly the same structure. The main body section 71 of one infusion tubing 7 is connected to the drip chamber 60 via a hose 70, so that the alcohol 201 in the drip chamber 60 flows into the flow regulator 10 from the hose 70 and the infusion tubing 7. The main body section 71 of the other infusion tubing 7 is connected to another hose 70, and the hose 70 is connected to the felt 401 of the slitting blade 402, so that the alcohol 201 in the flow regulator 10 drips onto the felt 401 through the infusion tubing 7 and the hose 70, thereby cleaning, cooling and removing static electricity from the slitting blade 402.

[0074] In this embodiment, the sealed cavity M includes a first end M1 and a second end M2. The first end M1 and the second end M2 are respectively two ends of the sealed cavity M in the length direction. When the magnetic rolling member 5 is located at the first end M1 of the sealed cavity M, the opening of the flow regulator 10 is the largest, and the dripping amount of the alcohol 201 through the flow regulator 10 is the largest. When the magnetic rolling member 5 is located at the second end M2 of the sealed cavity M, the opening of the flow regulator 10 is the smallest, and the dripping amount of the alcohol 201 through the flow regulator 10 is the smallest. When the magnetic rolling member 5 moves from the first end M1 to the second end M2, the opening of the flow regulator 10 gradually decreases, and the dripping amount of the alcohol 201 through the flow regulator 10 gradually decreases.

[0075] Please refer to Figure 5 , Figure 6 and Figure 7 , Figure 5 the structure diagram of the first sealing member of the flow regulator shown in Figure 3 , Figure 6 the cross-sectional view of the first sealing member along A-A shown in Figure 5 , Figure 7 the cross-sectional view of the first sealing member along B-B shown in Figure 5 .

[0076] The first sealing member 3 includes a first sealing surface 31 and a first connecting surface 32. The first sealing surface 31 and the first connecting surface 32 are arranged back to back in the thickness direction (i.e. the Z-axis direction) of the first sealing member 3. The first sealing member 3 further includes two first side surfaces 33. The two first side surfaces 33 are arranged back to back in the length direction (i.e. the Y-axis direction) of the first sealing member 3. The two first side surfaces 33 are connected to the first sealing surface 31 and the first connecting surface 32. In this embodiment, the first sealing member 3 has a substantially long rectangular structure. The first sealing member 3 is made of an elastically deformable plastic material.

[0077] The first sealing member 3 further comprises a first sealing groove 34. The first sealing groove 34 is concavely disposed on the first sealing surface 31 of the first sealing member 3 and recessed towards the first connecting surface 32. In the present embodiment, the first sealing groove 34 is substantially a rectangular groove. The length direction of the first sealing groove 34 is substantially the same as the length direction of the first sealing member 3, and the first sealing groove 34 is located at the middle position of the first sealing member 3. The length of the first sealing groove 34 is less than the length of the first sealing member 3, and the width of the first sealing groove 34 is less than the width of the first sealing member 3. The first sealing groove 34 is used for accommodating part of the magnetic rolling member 5. The first sealing groove 34 comprises a first groove bottom surface 341, two first groove side surfaces 342 and two second groove side surfaces 343. The orientation of the first groove bottom surface 341 is the same as the orientation of the first sealing surface 31.

[0092] It can be understood that the first sealing groove 34 and the second sealing groove 44 constitute a part of the sealing cavity M, and the first rolling groove 36, the second rolling groove 45 and the flow guide groove 35 can be regarded as grooves provided on the cavity wall of the sealing cavity M. The first end a of the flow guide groove 35 communicates with the first end portion M1 of the sealing cavity M, and the second end b communicates with the second end portion M2 of the sealing cavity M. In some embodiments, the flow guide groove 35 can be provided on the second sealing member 4 and recessed in the second groove bottom surface 441 of the second sealing groove 44.

[0093] Two infusion catheters 7 are respectively located at two ends of the sealing cavity M in the length direction, and both of the two infusion catheters 7 communicate with the sealing cavity M. A part of each infusion catheter 7 is arranged in a first pipe groove 37 of the first sealing member 3 and a second pipe groove 46 of the second sealing member 4, and another part of the infusion catheter 7 extends out of the first pipe groove 37 and the second pipe groove 46 and is located outside the sealing cavity M. Specifically, a part of the main body segment 71 of each infusion catheter 7 is located in a first sub-groove 371 of a first pipe groove 37 and a third sub-groove 461 of a second pipe groove 46, and is tightly clamped by the first sub-groove 371 and the third sub-groove 461. Another part of the main body segment 71 of each infusion catheter 7 extends out of the first sub-groove 371 and the third sub-groove 461 in a direction away from the sealing cavity M. The fixed segment 72 of each infusion catheter 7 is located in the first clamping groove 373 of the first pipe groove 37 and the second clamping groove 463 of the second pipe groove 46, and is tightly clamped by the first clamping groove 373 and the second clamping groove 463. In the embodiment, the fixed segment 72 of each infusion catheter 7 is accommodated in the first clamping groove 373 of the first sealing member 3 and the second clamping groove 463 of the second sealing member 4, and is clamped and matched with the first clamping groove 373 and the second clamping groove 463, so as to realize clamping and limiting of the infusion catheter 7 with the first sealing member 3 and the second sealing member 4, and prevent the infusion catheter 7 from falling off from the first sealing member 3 and the second sealing member 4, thereby affecting the flow effect of the alcohol 201.

[0094] As Figure 11 and Figure 12As shown, the magnetic rolling member 5 is installed in the sealed cavity M, and the magnetic rolling member 5 covers part of the slot 352 of the flow guide groove 35. The circumferential side surface 511 of the rolling body 51 is tightly connected with the first groove bottom surface 341 of the first sealing groove 34 and the second groove bottom surface 441 of the second sealing groove 44. The magnetic rolling member 5 rolls in the sealed cavity M along the direction from the first end to the second end M2 of the sealed cavity M, and the distance between the circumferential side surface 511 of the rolling body 51 and the flow guide groove wall 351 of the flow guide groove 35 gradually decreases, that is, the opening of the flow regulator 10 gradually becomes smaller, and vice versa. Each end surface 512 of the rolling body 51 is tightly connected with one second groove side surface 343 of the first sealing groove 34 and one fourth groove side surface 443 of the second sealing groove 44. Each rolling protrusion 52 of the magnetic rolling member 5 is tightly engaged with one first rolling groove 36 of the first sealing member 3 and one second rolling groove 45 of the second sealing member 4. In this embodiment, the rolling protrusions 52 of the magnetic rolling member 5 and the first rolling groove 36 and the second rolling groove 45 cooperate to ensure the movement track of the magnetic rolling member 5 when rolling along the Y-axis direction in the sealed cavity M. That is, the magnetic rolling member 5 can only roll along the length direction of the first rolling groove 36 and the second rolling groove 45.

[0095] In this embodiment, the first sealing member 3 and the second sealing member 4 both have the ability of elastic deformation, and can tightly clamp a part of the two infusion catheters 7 and the magnetic rolling member 5, and have interference fit with the part of the two infusion catheters 7 and the magnetic rolling member 5, so that the alcohol 201 flows into the flow guide groove 35 through one infusion catheter 7 and then flows out through the other infusion catheter 7, without leaking from the assembly gap between the first sealing member 3, the second sealing member 4 and the two infusion catheters 7, or flowing through the assembly gap between the magnetic rolling member 5 and the first sealing groove 34 and the second sealing groove 44, thereby realizing precise control of the opening of the flow regulator 10, that is, precise control of the alcohol 201 infusion amount.

The two side surfaces 613 are connected to the first surface 611 and the second surface 612. In the embodiment, the magnetic block 61 is substantially a rectangular block, and the magnetic pole center of the magnetic block 61 is located at the middle position of the magnetic block 61. That is, the center position of the magnetic block 61 has the maximum magnetic field strength.

[0111] The magnetic block 61 further comprises a limiting groove 614. The limiting groove 614 is recessed on the first surface 611 of the magnetic block 61 and recessed towards the second surface 612. The limiting groove 614 penetrates through the two side surfaces 613 of the magnetic block 61. The limiting groove 614 is used to accommodate part of the push slide 62, so as to ensure that the push slide 62 drives the magnetic block 61 to move when the push slide 62 is pushed. The groove bottom wall of the limiting groove 614 is recessed with a first accommodating groove 615. The number of the first accommodating groove 615 is one or more. The first accommodating groove 615 is used to accommodate part of the spring 63. In the embodiment, the number of the first accommodating groove 615 is two. Each first accommodating groove 615 is used to accommodate part of one spring 63.

[0112] The push slide 62 comprises a sliding body 621 and a pushing part 622. The sliding body 621 comprises a second limiting surface 623 and an assembly surface 624. The second limiting surface 623 and the assembly surface 624 are oppositely arranged along the thickness direction (i.e. the Z-axis direction) of the sliding body 621. The pushing part 622 is protruded on the second limiting surface 623 of the sliding body 621. In the embodiment, the sliding body 621 is a rectangular plate body, and the pushing part 622 is a cylindrical body with a semicircular cross section. Along the Z-axis direction, the pushing part 622 is provided with a scale arrow q at the end away from the sliding body 621, so as to clearly point to the scale on the second cover body 2 corresponding to the position of the magnetic pusher 6, and then the size of the opening of the flow regulator 10 at this time and the dripping amount of the alcohol 201 from the flow regulator 10 to the wool felt 401 on the slitting knife 402 can be inferred.

[0113] As shown in Figure 18 The sliding main body 621 further comprises a second accommodating groove 625. The second accommodating groove 625 is recessed on the assembly surface 624 of the sliding main body 621 and is recessed towards the pushing part 622. The number of the second accommodating groove 625 is one or more. The second accommodating groove 625 is used for accommodating a part of the spring 63. In the embodiment, the number of the second accommodating groove 625 is two. Each of the second accommodating groove 625 is used for accommodating a part of the spring 63.

[0114] In the embodiment, the sliding main body 621 of the pushing sliding cover 62 is assembled in the limiting groove 614 of the magnetic block 61, and the assembly surface 624 of the sliding main body 621 is opposite to the groove bottom wall of the limiting groove 614. The sliding main body 621 can move away from or close to the groove bottom wall of the limiting groove 614 along the thickness direction (i.e. the Z-axis direction) of the magnetic pushing device 6. Along the thickness direction of the magnetic pushing device 6, each of the second accommodating groove 625 of the sliding main body 621 is opposite to and coaxially arranged with one of the first accommodating groove 615 of the magnetic block 61. A part of each of the spring 63 is assembled in one of the second accommodating groove 625, and another part is assembled in one of the first accommodating groove 615. When the magnetic pushing device 6 needs to be pushed or does not need to be pushed, the spring 63 is always in a compressed state and generates a spring force along the Z-axis direction on the pushing sliding cover 62.

[0115] Please refer to Figure 19 , Figure 19 The partial structure of the flow regulator shown in Figure 2 is a cross-sectional view along E-E. It should be noted that Figure 19 the cross-sectional structure of the magnetic pushing device during being pushed.

[0116] In the embodiment, the magnetic pushing device 6 is slidingly connected to the second cover 2. Specifically, the magnetic block 61 and the sliding main body 621 of the pushing sliding cover 62 are both assembled in the sliding groove 27 of the second cover 2 and are clamped by the sliding bottom wall 271 of the sliding groove 27 and the two limiting protrusions 28. The second surface 612 of the magnetic block 61 abuts against the sliding bottom wall 271 of the sliding groove 27. The two side surfaces 613 of the magnetic block 61 respectively abut against the two sliding groove walls 272 of the sliding groove 27. The second limiting surface 623 of the sliding main body 621 is opposite to the first limiting surface 281 of the two limiting protrusions 28. The pushing part 622 of the pushing sliding cover 62 penetrates through the interval between the two limiting protrusions 28 and is clamped by the two limiting protrusions 28, so as to facilitate manually pressing the pushing sliding cover 62 and pushing the magnetic pushing device to slide along the length direction of the sliding groove 27. Moreover, the pushing part 622 is clamped by the two limiting protrusions 28, and the magnetic block 61 and the pushing sliding cover 62 are both limited in the sliding groove 27, so as to ensure the sliding track of the magnetic pushing device 6 when sliding in the sliding groove 27.

[0117] When the magnetic pusher 6 does not need to be pushed, the spring 63 will push the sliding cover 62 up and make the sliding body 621 abut against the two limiting protrusions 28. The sliding cover 62 is made of rubber material with large damping, and the sliding body 621 has large friction with the two limiting protrusions 28, so as to prevent the sliding cover 62 from sliding relative to the second cover 2, ensure the structural stability of the flow regulator 10, and further ensure the stability of the alcohol 201 infusion amount per unit time. When the magnetic pusher 6 needs to be pushed, the sliding cover is pressed in the direction of the Z axis to the direction of the magnetic block 61, the assembly surface 624 of the sliding body 621 abuts against the groove bottom wall of the limiting groove 614, and then the pushing part 622 is manually pushed to slide along the length direction of the sliding groove 27. According to actual needs, the scale arrow q of the magnetic pusher 6 points to the required scale on the second cover 2. During the process of pressing the sliding cover 62 in the direction of the Z axis, the spring 63 is gradually compressed, and the elastic force of the spring 63 on the sliding cover 62 gradually increases. After the adjustment of the scale arrow of the magnetic pusher 6 is completed, the Z-direction pressing force on the sliding cover 62 is released, and the elastic force of the spring 63 will push the sliding cover 62 in the direction of the Z axis away from the magnetic block 61, so that the sliding cover 62 abuts against the two limiting protrusions 28 again, that is, returns to the state when the magnetic pusher 6 does not need to be pushed.

[0118] Please refer to Figure 2 、 Figure 11 and Figure 20 , Figure 20 the cross-sectional view of the flow regulator along D-D shown in Figure 2 .

[0119] As shown in Figure 2 and Figure 20 , the first cover 1 covers the first sealing member 3. The second cover 2 covers the second sealing member 4. The first cover 1 and the second cover 2 are tightly connected by a plurality of fixing members 8, the first cover 1 and the second cover 2 are relatively closed, and tightly hold a part of the two infusion catheters 7, the first sealing member 3, the second sealing member 4 and the magnetic rolling member 5 in the sealing cavity M. In the embodiment, the fixing member 8 can be but is not limited to an internal hexagonal taper end set screw.

[0120] Specifically, in the embodiment, the first cover 1 and the second cover 2 are relatively closed along the Z-axis direction. The length of the first cover 1 and the length of the second cover 2 are substantially the same, and the width of the first cover 1 and the width of the second cover 2 are substantially the same. The first mounting surface 11 of the first cover 1 and the second mounting surface 21 of the second cover 2 are relatively abutted. The first surface 12 and the third side surface 13 of the first cover 1, and the second surface 22 and the fourth side surface 23 of the second cover 2 jointly constitute part of the outer surface of the shell 101. Each fixing hole 16 of the first cover 1 and one fixing groove 26 of the second cover 2 are coaxial and communicate. A part of each fixing member 8 is accommodated in one fixing hole 16 and one fixing groove 26, so as to realize the fastening connection of the first cover 1 and the second cover 2. Each third pipe groove 15 of the first cover 1 and one fourth pipe groove 25 of the second cover 2 are opposite and communicate.

[0121] The first sealing member 3 is accommodated in the first mounting groove 14 of the first cover 1, and the first connecting surface 32 of the first sealing member 3 is tightly connected with the groove bottom wall of the first mounting groove 14. The second sealing member 4 is accommodated in the second mounting groove 24 of the second cover 2, and the second connecting surface 42 of the second sealing member 4 is tightly connected with the groove bottom wall of the second mounting groove 24. A part of the infusion catheter 7 passing through the first pipe groove 37 of the first sealing member 3 and the second pipe groove 46 of the second sealing member 4 is located in the third pipe groove 15 of the first cover 1 and the fourth pipe groove 25 of the second cover 2, and another part passes through the third pipe groove 15 and the fourth pipe groove 25 to communicate with the hose 70.

[0122] In the embodiment, the magnetic block 61 of the magnetic pusher 6 and the magnetic rolling member 5 both have magnetism. The magnetic pusher 6 is installed on the second cover 2 and generates magnetic force with the magnetic rolling member 5 in the sealing cavity M. When the magnetic pusher 6 is pushed to slide along the length direction of the sliding groove 27, the magnetic rolling member 5 rolls along the length direction of the sealing cavity M under the interaction of the magnetic force.

[0123] In the embodiment, the magnetic pole center of the magnetic block 61 is arranged at the center position of the magnetic block 61. At this time, the magnetic force of the magnetic block 61 on the magnetic rolling member 5 is the largest, which ensures that the magnetic rolling member 5 can always be kept in the central alignment with the magnetic block 61 during the process that the magnetic pusher 6 is pushed and stationary, that is, the magnetic pusher 6 and the magnetic rolling member 5 are synchronously linked, which is beneficial to realize the precise adjustment of the opening of the flow regulator 10, that is, the precise adjustment of the alcohol 201 infusion amount.

[0124] In the embodiment, the scale mark Q on the second cover 2 cooperates with the scale arrow q on the magnetic pusher 6, and the flow regulator 10 is synchronously linked through the magnetic force of the magnetic pusher 6 and the internal magnetic roller 5. When it is necessary to adjust the infusion amount of the alcohol 201, it is only necessary to point the scale arrow q of the magnetic pusher 6 to the target scale on the second cover 2 according to the requirement, and the magnetic pusher 6 synchronously drives the magnetic roller 5 to move, so as to adjust the opening degree of the flow regulator 10, and then the required infusion amount of the alcohol 201 is obtained. Not only the structural sealing of the flow regulator 10 is not affected, but also the structural sealing failure is avoided to cause the alcohol 201 in the sealed cavity M to leak, and the infusion amount of the alcohol 201 in unit time can be accurately controlled.

[0125] In the process of adjusting the opening degree of the flow regulator 10, the first cover 1 and the second cover 2 tightly hold the first sealing piece 3 and the second sealing piece 4, and the first sealing piece 3 and the second sealing piece 4 do not slide relative to each other, which avoids the poor structural sealing caused by the dislocation between the first sealing piece 3 and the second sealing piece 4, and avoids the abrasion caused by the friction between the first sealing piece 3 and the second sealing piece 4, improves the service life of the entire flow regulator 10, and reduces the risk of the alcohol 201 leaking from the flow regulator 10 and dripping on the pole piece.

[0126] In the embodiment, one infusion catheter 7 close to the first end a of the flow guide groove 35 is in communication with the hose 70 connected to the drip bottle 60, and the other infusion catheter 7 close to the second end b of the flow guide groove 35 is in communication with the hose 70 connected to the slitting knife 402. When the slitting device 1000 is running, the alcohol 201 flows from the drip bottle 60 to the first end a of the flow guide groove 35 through the hose 70 and the infusion catheter 7, and flows from the second end b of the flow guide groove 35 to the slitting knife 402 through the infusion catheter 7 and the hose 70. When the magnetic roller 5 is located at the first end a of the flow guide groove 35, the opening degree of the flow regulator 10 is maximum, that is, the infusion amount of the alcohol 201 to the slitting knife 402 is maximum. When the magnetic roller 5 is located at the second end b of the flow guide groove 35, the opening degree of the flow regulator 10 is minimum, that is, the infusion amount of the alcohol 201 to the slitting knife 402 is minimum. In some embodiments, one infusion catheter 7 close to the first end a of the flow guide groove 35 can be in communication with the hose 70 connected to the slitting knife 402, and the other infusion catheter 7 close to the second end b of the flow guide groove 35 can be in communication with the hose 70 connected to the drip bottle 60.

[0127] In the related art, the device for cleaning, cooling and removing static electricity of the slitting knife is an alcohol dripping device. In the alcohol dripping device, alcohol flows out from the alcohol barrel by gravity, and flows through the electromagnetic valve, the flow divider, the throttle valve and the dropper in turn through the hose, and finally drips onto the wool felt on the slitting machine knife below the dropper. However, as the alcohol liquid level in the alcohol barrel decreases, the amount of alcohol dripping from the alcohol barrel gradually decreases, making the dripping amount of alcohol unstable. Moreover, alcohol forms different flow paths through the flow divider, and is affected by various factors such as the length, curvature, input and output distances of the hose, and the alcohol dripping amount through different flow paths to the corresponding slitting machine table has a large difference; further, the existing alcohol dripping device cannot accurately control the alcohol dripping amount of the slitting knife, so it cannot guarantee the quality and consistency of the slitting product.

[0128] In the embodiment of the present application, the alcohol dripping device 100 is provided with a flow regulator 10 between the dropper 60 and the wool felt 401, and the flow regulator 10 is synchronously linked by the magnetic force between the magnetic pusher 6 and the magnetic roller 5 to adjust the dripping amount of alcohol 201. Specifically, according to the demand for the dripping amount of alcohol 201, the magnetic pusher 6 is pushed up and down to slide on the shell 101, so that the magnetic roller 5 in the sealing cavity M in the sealing part 102 is in different positions, and the opening of the flow regulator 10 is accurately controlled, that is, the dripping amount of alcohol 201 per unit time from the flow regulator 10 to the wool felt 401 on the slitting knife 402 is accurately adjusted, so that alcohol 201 is evenly and slowly dripped, avoiding the saturation of alcohol 201 on the wool felt 401 after the dripping amount of alcohol 201 is too much, causing the electrode sheet to fall off, and also avoiding the fact that a large amount of alcohol 201 remaining on the slitting knife 402 will adhere to the metal scraps of the slitting foil and cannot be sucked away by the negative pressure dust collector, causing the metal scraps to accumulate and the viscosity electrode sheet to be wrapped into the battery cell, resulting in product safety risks, improving the stability and safety of the alcohol dripping device 100 during the working process. At the same time, it also avoids the fact that too little dripping amount of alcohol 201 causes the slitting knife 402 to overheat, shortens the service life, and reduces the quality of the slitting electrode sheet end surface 512. In the embodiment, the flow regulator 10 can accurately control the dripping amount of alcohol 201, and alcohol 201 can be evenly and slowly dripped to the wool felt 401 through the flow regulator 10, ensuring that the slitting knife 402 always has uniform and appropriate alcohol 201 for cleaning, cooling and removing static electricity during the working process, improving the cleaning, cooling and static electricity removal effect of the slitting knife 402, and further ensuring the quality and consistency of the slitting product after being cut by the slitting knife 402.

[0129] Moreover, even if the alcohol dripping device 100 is used for alcohol 201 dripping of multiple slitting knives 402, since the dripping amount of alcohol is controlled by the flow regulator 10, and the dripping mode is uniform and continuous dripping, the flow of alcohol 201 in the flow regulator 10 is less than the flow of alcohol 201 after the shunt 40, not only ensuring that the shunt 40 can sufficiently supply the alcohol 201 capacity in the flow regulator 10 of each shunt path, but also weakening the phenomenon that the dripping amount of alcohol 201 exists due to different shunt paths after shunting, realizing the consistency control of the dripping amount of alcohol 201 of each slitting knife 402, improving the slitting quality of different slitting knives 402, and further improving the quality and consistency of the slitting products after slitting of different slitting knives 402.

[0130] In addition, in the existing alcohol dripping device, the electromagnetic valve controls the intermittent and large amount of alcohol dripping onto the wool felt of the slitting knife through the timing on-off control logic, and too much alcohol dripping amount can easily affect the slitting effect of the slitting knife, and further affect the quality and consistency of the slitting product. Moreover, the existing alcohol dripping device cannot accurately observe the amount of alcohol dripping, and further cannot visually judge whether the dripping amount of alcohol meets the standard.

[0131] In the embodiment of the present application, the electromagnetic valve 30 is changed from timing on-off control to always open when the slitting equipment 1000 is running, and the electromagnetic valve 30 is disconnected when the slitting equipment 1000 is running abnormally. When the slitting equipment 1000 is running, the electromagnetic valve 30 is opened, cooperating with the precise control of the flow regulator 10 on the dripping amount of alcohol 201, realizing the quantitative dripping of alcohol 201 in unit time, avoiding too much alcohol 201 dripping amount affecting the slitting effect of the slitting knife 402, and further ensuring the quality and consistency of the slitting product. Moreover, the dropper 60 in the embodiment is made of transparent material, after adjusting the scale corresponding to the magnetic pusher 6 according to the actual demand, the number of alcohol 201 drops in unit time is visually observed through the transparent dropper 60, and the point inspection (such as opening class point inspection, process inspection, etc.) is carried out, which can realize the quantitative dripping of alcohol 201 and the visual and standardized control of alcohol 201 dripping.

[0132] The above is only part of the embodiments and implementation modes of the present application, the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
