[0014] The electrode slitting device 10 according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0015] Reference Figures 1-6 As shown, the electrode slitting device 10 includes a slitting mechanism 2 and an outlet adjustment mechanism 1. The slitting mechanism 2 is used to slit the electrode 201 into multiple sub-electrodes 202 in the width direction of the electrode 201. The outlet adjustment mechanism 1 is located on the side where the slitting mechanism 2 outputs the multiple sub-electrodes 202. The outlet adjustment mechanism 1 includes a support shaft 11, an outlet height adjustment component 14, multiple eccentric sleeves 12, and multiple rollers 13. The axial direction of the support shaft 11 is parallel to the width direction of the electrode 201, and the multiple eccentric sleeves... 12. Multiple rollers 13 and multiple sub-electrode pieces 202 correspond one-to-one. An eccentric sleeve 12 is sleeved and fixed to the support shaft 11. The projections of two adjacent eccentric sleeves 12 on a plane perpendicular to the axis of the support shaft 11 do not completely overlap. The rollers 13 are rotatably sleeved on the corresponding eccentric sleeves 12. The sub-electrode pieces 202 are in contact with part of the outer roller surface of the corresponding rollers 13. The outlet height adjustment component 14 is connected to the support shaft 11. The outlet height adjustment component 14 is used to adjust the position of the support shaft 11 in the first direction.

[0016] Specifically, the electrode cutting device 10 can cut the electrode 201 through the cutting mechanism 2, so that the electrode 201 is cut in its width direction ( Figure 1 The electrode is divided into multiple sub-electrodes 202 in the left-right direction. The outlet adjustment mechanism 1 is located on the side where the multiple sub-electrodes 202 are output from the slitting mechanism 2. The outlet adjustment mechanism 1 can make the conveying direction of the slitting sub-electrodes 202 staggered to avoid adjacent sub-electrodes 202 colliding and rubbing against each other during conveying. The outlet adjustment mechanism 1 can also adjust the wrap angle formed by the electrode 201 with the cutter of the slitting mechanism 2 to ensure the slitting quality of the electrode 201 by the slitting mechanism 2.

[0017] In the outlet adjustment mechanism 1, the support shaft 11 can be fixed on the outlet height adjustment component 14. The eccentric sleeve 12 can be a hollow cylindrical mechanism, and the axis of the outer peripheral surface 121 of the eccentric sleeve 12 is parallel to and not collinear with the axis of the inner peripheral surface 122. The inner peripheral surface 122 of the eccentric sleeve 12 is sleeved and fixed to the support shaft 11, that is, the axis of the inner peripheral surface 122 of the eccentric sleeve 12 is collinear with the axis of the support shaft 11. The roller 13 can be rotatably sleeved on the outer peripheral surface 121 of the corresponding eccentric sleeve 12 through the connecting bearing 15. The sub-electrode 202 is in contact with part of the outer roller surface of the corresponding roller 13. When the electrode slitting device 10 is working, the sub-electrode 202 is driven around the corresponding roller 13, and the roller 13 rotates around the axis of the outer peripheral surface 121 of the eccentric sleeve 12.

[0018] The projections of two adjacent eccentric sleeves 12 onto a plane perpendicular to the axis of the support shaft 11 are not completely coincident. In other words, the installation angles of the two adjacent eccentric sleeves 12 are different in the circumferential direction of the support shaft 11. That is, the axes of the outer circumferential surfaces 121 of the two adjacent eccentric sleeves 12 are not collinear, which makes the rotation axes of the two adjacent rollers 13 different. This results in the belt-running directions of the two adjacent sub-electrodes 202 being staggered to avoid collisions and friction between the adjacent sub-electrodes 202.

[0019] The outlet height adjusting component 14 is connected to the support shaft 11. The outlet height adjusting component 14 is used to adjust the position of the support shaft 11 in a first direction, which can be... Figure 3 In the vertical direction, the outlet height adjustment component 14 can drive the support shaft 11 to move up and down in the vertical direction, thereby changing the overall direction of the conveyor belt of each sub-electrode 202. This allows the wrap angle formed by the section electrode 201 and the cutter of the slitting mechanism 2 to be a preset slitting wrap angle, so as to ensure the slitting quality of the electrode 201 by the slitting mechanism 2.

[0020] According to the embodiment of the present utility model, the electrode cutting device 10 has an outlet adjustment mechanism 1 that can adjust the wrap angle formed by the electrode 201 with the cutter of the cutting mechanism 2. By setting oblique sleeves with different installation angles on the support shaft 11, the conveying directions of two adjacent sub-electrodes 202 can be staggered. The outlet adjustment mechanism 1 has a simple structure and occupies little space. When the electrode 201 or sub-electrodes 202 needs to be re-threaded, the operator can easily perform the threading operation at the outlet adjustment mechanism 1.

[0021] In some embodiments, the outlet height adjustment component 14 is constructed as a ball screw, and the slider of the ball screw can be connected to the support shaft 11. The screw can drive the slider to move the support shaft 11 up and down in the vertical direction. The ball screw has high adjustment accuracy and reliability.

[0022] In other embodiments, the outlet height adjustment member 14 is configured as a hydraulic telescopic rod, one end of which is connected to the support shaft 11. The hydraulic telescopic rod can drive the support shaft 11 to move up and down in the vertical direction by extending and retracting.

[0023] In some embodiments of this utility model, reference is made to Figure 3 As shown, there are two outlet height adjustment components 14. The two outlet height adjustment components 14 are respectively connected to the two ends of the axial direction of the support shaft 11. The two outlet height adjustment components 14 can synchronously drive the support shaft 11 to rise and fall.

[0024] In some embodiments of this utility model, reference is made to Figures 1-3 As shown, each sub-electrode 202 is in contact with a portion of the outer roller surface of the corresponding roller 13 on the same side of the support shaft 11. That is, in the circumferential direction of the support shaft 11, the angle difference between the contact area of ​​each sub-electrode 202 and the outer roller surface of the roller 13 does not exceed 180°, so as to avoid multiple sub-electrodes 202 being distributed on the upper and lower sides of the support shaft 11 and reduce the difficulty of threading the sub-electrodes 202 at the outlet adjustment mechanism 1.

[0025] In some embodiments of this utility model, the installation angle of the eccentric sleeve 12 relative to the support shaft 11 is adjustable in the circumferential direction of the support shaft 11.

[0026] Specifically, when adjusting the installation angle of the eccentric sleeve 12 relative to the support shaft 11 in the circumferential direction of the support shaft 11, the axial position of the outer circumferential surface 121 of the eccentric sleeve 12 changes accordingly, thereby changing the rotation axis of the roller 13 sleeved on the eccentric sleeve 12, thereby realizing the individual adjustment of the belt-carrying direction of the sub-electrode 202, so as to improve the adjustment flexibility of the outlet adjustment mechanism 1.

[0027] In some embodiments of this utility model, reference is made to Figures 3-6As shown, the eccentric sleeve 12 has a radial connecting hole 123. The radial connecting hole 123 is selectively fixed to the support shaft 11 by fasteners, so that the installation angle of the eccentric sleeve 12 relative to the support shaft 11 can be adjusted.

[0028] Specifically, when the fastener is tightened, it securely connects the eccentric sleeve 12 to the support shaft 11, preventing the eccentric sleeve 12 from rotating relative to the support shaft 11. When it is necessary to adjust the installation angle of the eccentric sleeve 12, the fastener can be loosened, allowing the eccentric sleeve 12 to rotate around the support shaft 11, thereby changing the axial position of the outer circumferential surface 121 of the eccentric sleeve 12. The fastener can be a screw or a pin.

[0029] In some embodiments of this utility model, reference is made to Figure 4 and Figure 6 As shown, there are multiple radial connecting holes 123, which are arranged at intervals along the circumferential direction of the eccentric sleeve 12. Each radial connecting hole 123 can be connected to the support column by a corresponding fastener, so as to improve the stability and reliability of the connection between the eccentric sleeve 12 and the support shaft 11, and improve the load-bearing capacity of the eccentric sleeve 12.

[0030] In some other embodiments of this utility model (not shown in the figures), the eccentric sleeve 12 can also be selectively fixed to the support shaft 11 by a ratchet and pawl mechanism, so as to realize that the installation angle of the eccentric sleeve 12 relative to the support shaft 11 is adjustable.

[0031] In some embodiments of this utility model, in the circumferential direction of the support shaft 11, the installation angles of two adjacent eccentric sleeves 12 differ by 90° to 270°.

[0032] Specifically, in the circumferential direction of the support shaft 11, when the installation angles of two adjacent eccentric sleeves 12 differ by 0°, the projections of the two adjacent eccentric sleeves 12 onto the plane perpendicular to the axis of the support shaft 11 completely coincide. At this time, with one eccentric sleeve 12 fixed, and the other eccentric sleeve 12 rotated 90° to 270° around the axis of the support shaft 11, the installation angles of the two adjacent eccentric sleeves 12 will differ by 90° to 270° respectively. (Refer to...) Figure 3 As shown, the installation angles of two adjacent eccentric sleeves 12 differ by 180°, so that the direction of the belt travel of the two adjacent sub-electrodes 202 is offset by a larger angle, thereby reducing the risk of the two adjacent sub-electrodes 202 colliding and rubbing against each other.

[0033] In some embodiments of this utility model, reference is made to Figure 7 As shown, the slitting mechanism 2 includes a first blade group 21 and a second blade group 22, which are arranged opposite to each other in the thickness direction of the electrode sheet 201.

[0034] The first blade assembly 21 includes: a first driver 211, a first spindle 212, a first cutter 213, and a first bracket 214. The first driver 211 is connected to the first spindle 212 in a transmission manner. The first cutter 213 is sleeved and fixed on the first spindle 212. The first spindle 212 is rotatably inserted through the first bracket 214.

[0035] Specifically, the first driver 211 can be a motor or an engine. The first driver 211 can be connected to the first spindle 212 via the first coupling 215. The first driver 211 can drive the first spindle 212 to rotate around its axis. The first cutter 213 is sleeved and fixed on the first spindle 212. The first cutter 213 can rotate synchronously with the first spindle 212 to cut the electrode sheet 201. The first bracket 214 can be provided with multiple first bearing seats 2141. The first spindle 212 passes through each first bearing seat 2141 and is rotatably connected to the first bearing seat 2141 via the corresponding first bearing 2142. The structure of the first cutter group 21 is simple and reliable.

[0036] The second blade assembly 22 includes: a second driver 221, a second spindle 222, a second cutter 223, and a second bracket 224. The second driver 221 is connected to the second spindle 222 in a transmission manner. The second cutter 223 is sleeved and fixed on the second spindle 222. The second spindle 222 is rotatably inserted through the second bracket 224.

[0037] Specifically, the second driver 221 can be a motor or an engine. The second driver 221 can be connected to the second spindle 222 via the second coupling 225. The second driver 221 can drive the second spindle 222 to rotate around its axis. The second cutter 223 is sleeved and fixed on the second spindle 222. The second cutter 223 can rotate synchronously with the second spindle 222 to cut the electrode 201. The second bracket 224 can be provided with multiple second bearing seats 2241. The second spindle 222 passes through each second bearing seat 2241 and is rotatably connected to the second bearing seat 2241 through the corresponding second bearing 2242. The structure of the second cutter group 22 is simple and reliable.

[0038] In some embodiments of this utility model, reference is made to Figure 7 As shown, the first blade assembly 21 further includes: a plurality of first spacers 216, in the axial direction of the first spindle 212, both sides of the first cutter 213 are connected to the first spindle 212 through at least one first spacer 216. The second blade assembly 22 further includes: a plurality of second spacers 226, in the axial direction of the second spindle 222, both sides of the second cutter 223 are connected to the first spindle 212 through at least one second spacer 226.

[0039] Specifically, the axial directions of the first spindle 212 and the second spindle 222 are both parallel to the width direction of the electrode 201. The left and right sides of the first cutter 213 are clamped by the first spacers 216. The first cutter 213 can be fixedly connected to the first spindle 212 through the first spacers 216. By increasing or decreasing the number of first spacers 216 on each side, the position of the first cutter 213 in the axial direction (left and right direction) of the first spindle 212 can be adjusted. The left and right sides of the second cutter 223 are clamped by the second spacers 226. The second cutter 223 can be fixedly connected to the second spindle 222 through the second spacers 226. By increasing or decreasing the number of second spacers 226 on each side, the position of the second cutter 223 in the axial direction (left and right direction) of the second spindle 222 can be adjusted. Thus, by adjusting the positions of the first cutter 213 and the second cutter 223 in the left and right directions, the cutting position of the electrode 201 by the slitting mechanism 2 in the left and right directions can be adjusted, thereby improving the versatility of the slitting mechanism 2. In addition, by adjusting the positions of the first cutter 213 and the second cutter 223 in the left and right directions, the cutting amount of the slitting mechanism 2 can also be adjusted.

[0040] In some embodiments of this utility model, reference is made to Figure 1 , Figure 2 and Figure 8 As shown, the electrode slitting device 10 further includes an inlet adjustment mechanism 3. The inlet adjustment mechanism 3 is located on the side of the electrode 201 input by the slitting mechanism 2. The inlet adjustment mechanism 3 includes an adjustment roller 31 and an inlet height adjustment member 32. The axial direction of the adjustment roller 31 is parallel to the width direction of the electrode 201. The electrode 201 is in contact with part of the outer roller surface of the adjustment roller 31. The adjustment roller 31 is rotatably connected to the inlet height adjustment member 32. The inlet height adjustment member 32 is used to adjust the position of the adjustment roller 31 in a first direction.

[0041] Specifically, the inlet adjustment mechanism 3 can adjust the direction of the belt when the electrode 201 enters the electrode slitting device 10, so as to improve the adjustable range of the wrap angle formed by the cutter of the slitting mechanism 2 on the electrode 201, and ensure the slitting quality of the electrode 201 by the slitting mechanism 2.

[0042] The adjusting roller 31 is rotatably connected to the inlet height adjusting member 32, which is used to adjust the position of the adjusting roller 31 in a first direction. The first direction can be... Figure 8 In the vertical direction, the inlet height adjustment component 32 can drive the adjustment roller 31 to rise and fall in the vertical direction, thereby changing the overall direction of the electrode sheet 201 that is in contact with the outer roller surface of the adjustment roller 31. This can increase the adjustable range and flexibility of the wrap angle formed by the electrode sheet 201 with the cutter of the slitting mechanism 2, so that the wrap angle formed by the electrode sheet 201 with the cutter of the slitting mechanism 2 is a preset slitting wrap angle, thus ensuring the slitting quality of the electrode sheet 201 by the slitting mechanism 2.

[0043] In some embodiments of this utility model, the outlet adjustment mechanism 1 and the inlet adjustment mechanism 3 adjust the wrap angle formed by the electrode 201 and the cutter of the slitting mechanism 2 to between 150° and 175°.

[0044] It should be noted that the wrap angle formed by the electrode 201 and the cutter of the slitting mechanism 2 can be the angle between the electrode 201 and the sub-electrode 202, that is... Figure 2 α1 and α2 are both located between 150° and 175°.

[0045] In some embodiments, the inlet height adjustment member 32 is constructed as a ball screw, and the adjustment roller 31 is rotatably connected to the slider of the ball screw mechanism. The screw can drive the slider to move the adjustment roller 31 up and down in the vertical direction. The ball screw adjustment has high accuracy and reliability.

[0046] In other embodiments, the inlet height adjustment member 32 is constructed as a hydraulic telescopic rod, one end of which is connected to the adjusting roller 31. The hydraulic telescopic rod can drive the adjusting roller 31 to move up and down in the vertical direction by extending and retracting.

[0047] In some embodiments of this utility model, reference is made to Figure 8 As shown, there are two inlet height adjusting components 32. The two inlet height adjusting components 32 are respectively connected to the two ends of the axial direction of the adjusting roller 31. The two inlet height adjusting components 32 can synchronously drive the adjusting roller 31 to rise and fall.

[0048] Reference Figure 1 As shown, the electrode slitting device 10 also includes multiple rollers 4, which can be located outside the inlet adjustment mechanism 3 and the outlet adjustment mechanism 1 to control the belt direction of the electrode 201 or sub-electrode 202, so that the corresponding electrode 201 or sub-electrode 202 is taut.
