[0028] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0029] Combine Figure 1 and Figure 2 As shown, an adjustable roller group mechanism 10 of an embodiment includes a swing arm shaft 300, a first fixing member 100, a second fixing member 200 and a stretching roller group 400, and the stretching roller group 400 includes a connecting rod 410 and a guide roller 420; the first fixing member 100 and the second fixing member 200 are both fixed to the swing arm shaft 300, and the first fixing member 100 and the second fixing member 200 are arranged in parallel; the guide roller 420 is rotatably sleeved on the connecting rod 410, and the stretching roller group 400 is located between the first fixing member 100 and the second fixing member 200, and the two ends of the connecting rod 410 are respectively protruded with a fixed end 4110 and an adjustment end 4120; the fixed end 4110 is fixedly connected to the first fixing member 100, and the adjustable roller group mechanism 10 also includes a first adjustment block 500, a second adjustment block 600, a connecting block 700, The tensioning member 800 and the adjustment block 900; the first adjustment block 500 and the second adjustment block 600 are both installed on the second fixing member 200, the adjustment end 4120 of the first adjustment block 500 is connected to the horizontal side of the adjustment block 900, so that the adjustment block 900 can be adjusted horizontally relative to the connecting block 700; the adjustment end 4120 of the second adjustment block 600 is connected to the vertical side of the adjustment block 900, so that the adjustment block 900 can be adjusted vertically relative to the connecting block 700; the first adjustment block 500 is provided with a tensioning through-hole 530, and the adjustment block 900 is provided with a tensioning lock hole 910, the tensioning member 800 is screwed to the tensioning lock hole 910 through the tensioning through-hole 530, the connecting block 700 and the adjustment block 900 jointly form a connecting cavity 4121, and the adjustment end 4120 is fixed in the connecting cavity 4121.

[0030] The guide roller 420 is adjustably mounted between the first fixing member 100 and the second fixing member 200 through the first fixing member 100 and the second fixing member 200, and the guide roller 420 is connected by the connecting rod 410. Because the adjusting end 4120 of the first adjusting block 500 is connected to the horizontal side of the adjusting block 900, the adjusting block 900 can be adjusted in the horizontal direction relative to the connecting block 700, so that the guide roller 420 can move left and right relative to the first fixing member 100 through the first adjusting block 500. At the same time, the adjusting end 4120 of the second adjusting block 600 is connected to the vertical side of the adjusting block 900, so that the adjusting block 900 can be adjusted in the vertical direction relative to the connecting block 700, so that the guide roller 420 can move up and down relative to the first fixing member 100 through the second adjusting block 600; because the first adjusting block 500 A tightening through-hole 530 is opened, and the tightening piece 800 is screwed to the tightening lock hole 910 through the tightening through-hole 530. The guide roller 420 can be adjusted left and right by twisting the locking piece, and the connecting block 700 and the adjusting block 900 form a connecting cavity 4121, so that the adjusting end 4120 of the connecting rod 410 is fixed in the connecting cavity 4121. The position of the adjusting end 4120 of the connecting rod 410 in the connecting cavity 4121 is adjusted by the first adjusting block 500 and the second adjusting block 600, thereby changing the position relationship of the guide roller 420 relative to the first fixing piece 100. When the operator disassembles the guide roller 420 to replace the electrode, the position of the guide roller 420 can be changed by adjusting the first adjusting block 500 and the second adjusting block 600 according to the requirements of the battery electrode specifications, thereby meeting the requirements of battery electrode rollers of various specifications.

[0031] Combine Figure 2 As shown, in one embodiment, the first adjustment block includes a first fixing block 510 and a first adjusting bolt 520. The first fixing block 510 is detachably connected to the second fixing member 200. The first fixing block 510 is provided with a first through-hole 511. The vertical side of the adjustment block 900 is provided with a first locking hole 930. The first adjusting bolt 520 is screwed into the first locking hole 930 through the first through-hole 511. It can be understood that the first fixing block 510 is provided on the second fixing member 200, and the first fixing block 510 is provided with a first through-hole 511. The vertical side of the adjustment block 900 is provided with a first locking hole 930. The first adjusting bolt 520 is screwed into the first locking hole 930 through the first through-hole 511, so that the left and right position of the adjustment block 900 relative to the second fixing member 200 can be adjusted by screwing the first adjusting bolt 520, thereby changing the position of the guide roller 420.

[0032] Combine Figure 1 and Figure 2As shown, in one embodiment, a reference surface 210 is provided at the bottom of the second fixing member 200, and the second adjustment block 600 is mounted on the reference surface 210. It can be understood that the reference surface 210 is provided at the bottom of the second fixing member, and the second adjustment block 600 is mounted on the reference surface 210. The second adjustment block 600 is always fixed on the reference surface 210. When the second adjustment block 600 is used to change the positional relationship of the guide roller 420, the reference surface 210 serves as the installation reference of the second adjustment block 600, which helps to ensure the accuracy of the second adjustment block 600 during the adjustment process. By precisely controlling the relative position between the second adjustment component and the reference surface 210, fine adjustment of the position of the stretching roller group 400 can be achieved.

[0033] Combine Figure 2 and Figure 3 As shown, further, the second adjustment block 600 of the adjustable roller assembly mechanism 10 includes a second fixed block 610, an adjustment block 900, and a second adjustment bolt 620. The second fixed block 610 and the adjustment block 900 are attached to the reference surface 210 and are detachably connected to the second fixing member 200. The second fixed block 610 and the adjustment block 900 are provided with a second through hole 6110. The adjustment block 900 is provided with a second locking hole 920. The second adjustment bolt 620 is screwed into the second locking hole 920 through the second through hole 6110. It can be understood that because the second adjustment block 610 is provided with the second through hole 6110 and the adjustment block 900 is provided with the second locking hole 920, when the second adjustment bolt 620 is turned, the height of the guide roller 420 can be changed up and down through the second adjustment block 600.

[0034] Combine Figure 2 As shown, specifically, the adjustment block 900 is slidably abutted against the upper surface of the second fixed block 610. It can be understood that by sliding the adjustment block 900 against the upper surface of the second fixed block 610, the position of the adjustment block 900 can be changed when the second adjustment bolt 620 is screwed. At the same time, the sliding abutment against the upper surface of the second fixed block 610 can adjust the tightness of the second adjustment block 600, thereby changing the tightness of the guide roller 420 with respect to the second adjustment block 600 as needed.

[0035] like Figure 1As shown, in one embodiment, the connecting rod 410 includes a connecting rod 410 body and a rotating bearing 4140. The outer ring of the rotating bearing 4140 is sleeved on the guide roller 420, and the inner ring of the rotating bearing 4140 is sleeved in the mounting hole of the guide roller 420. It can be understood that by providing the rotating bearings 4140 at both ends of the guide roller 420, and the rotating bearings 4140 are sleeved on the connecting rod body 4130, and the inner ring of the rotating bearings 4140 is sleeved in the mounting hole of the guide roller 420, when the battery electrode sheet is installed on the guide roller 420, the situation of excessive friction between the guide roller 420 and the connecting rod 410 due to long-term operation of the guide roller 420, thereby avoiding damage to the guide roller 420 and the connecting rod 410. The rotating bearing 4140 is sleeved on the connecting rod 410, ensuring that the connecting rod 410 can stably support the guide roller 420.

[0036] like Figure 2 As shown, the drive assembly 1000 further includes a drive connector 1300 and a cylinder driver 1400. The cylinder driver 1400 is mounted on a machine frame. A power output end 1410 of the cylinder driver 1400 is rotatably connected to one end of the drive connector 1300, and the other end of the drive connector 1300 is rotatably connected to the swing arm shaft 300. It can be understood that when the cylinder driver is mounted on a machine frame, and the power output end 1410 of the cylinder driver 1400 is rotatably connected to the drive connector 1300, and the other end of the drive connector 1300 is rotatably connected to the swing arm shaft 300, when the power output end 1410 of the cylinder driver 1400 rotates, the drive connector 1300 is driven to move. At the same time, because the other end of the drive connector 1300 is rotatably connected to the swing arm shaft 300, the swing arm shaft 300 moves along the direction of movement of the drive connector 1300.

[0037] Combine Figure 1 and Figure 2As shown, in one embodiment, the driving assembly 1000 also includes a convex cover 1100 and a swing bearing member 1200, the convex cover 1100 is provided with a accommodating cavity 1110, the outer ring of the swing bearing member 1200 is arranged in the accommodating cavity 1110, the inner ring of the swing bearing member 1200 is sleeved on the swing arm shaft 300, and the convex cover 1100 is connected to the driving connecting member 1300. It can be understood that a convex cover 1100 is provided on the side of the first fixing member 100 and the side of the second fixing member 200 respectively, and a swing bearing member 1200 is provided in the convex cover 1100. The two ends of the swing arm shaft 300 are respectively rotatably connected to the swing bearing members 1200 where the first fixing member 100 and the second fixing member 200 are located. When the swing arm shaft 300 rotates, because the two ends of the swing arm shaft 300 are rotatably connected to the swing bearing members 1200, the swing arm shaft 300 can swing more smoothly and reduce the burden of the force on the swing arm shaft 300.

[0038] Combine Figure 1 and Figure 2 As shown, specifically, the driving assembly 1000 also includes a pivot member 1500, the power output end 1410 of the cylinder driver 1400 is provided with a connected pivot hole 1510 and a rotation avoidance opening 1520, the driving connecting member 1300 is provided with a rotation hole 1521 at the end of the rotation avoidance opening 1520, and the pivot member 1500 is respectively penetrated through the pivot hole 1510 and the rotation hole 1521. It can be understood that the cylinder driver 1400 is connected to the pivot member 1500 through the pivot hole 1510. When the cylinder driver 1400 moves upward, it drives the pivot member 1500 to move. At the same time, the pivot member 1500 is rotationally connected to the driving connection member 1300 through the rotating hole 1521, further enabling the pivot member 1500 to drive the driving connection member 1300 to move, and the pivot member 1500 is provided with a rotation avoidance opening 1520. When the driving connection member 1300 moves, the rotation avoidance opening 1520 avoids the pivot member 1500 from colliding with the driving connection member 1300.

[0039] A pole piece pressing roller device includes the adjustable roller assembly mechanism 10 described in any of the above embodiments. It is understood that the position of the adjusting end 4120 of the connecting rod 410 in the connecting cavity 4121 is adjusted by the first adjustment block 500 and the second adjustment block 600, thereby changing the positional relationship of the guide roller 420 relative to the first fixing member 100. When the operator removes the guide roller 420 to replace the pole piece, the position of the guide roller 420 can be changed by adjusting the first adjustment block 500 and the second adjustment block 600 according to the required specifications of the battery pole piece, thereby meeting the requirements of various specifications of the battery pole piece pressing roller.

[0040] Compared with the prior art, the present disclosure has at least the following advantages:

[0041] The guide roller 420 is adjustably mounted between the first fixing member 100 and the second fixing member 200 through the first fixing member 100 and the second fixing member 200, and the guide roller 420 is connected by the connecting rod 410. Because the adjusting end 4120 of the first adjusting block 500 is connected to the horizontal side of the adjusting block 900, the adjusting block 900 can be adjusted in the horizontal direction relative to the connecting block 700, so that the guide roller 420 can move left and right relative to the first fixing member 100 through the first adjusting block 500. At the same time, the adjusting end 4120 of the second adjusting block 600 is connected to the vertical side of the adjusting block 900, so that the adjusting block 900 can be adjusted in the vertical direction relative to the connecting block 700, so that the guide roller 420 can move up and down relative to the first fixing member 100 through the second adjusting block 600; because the first adjusting block 500 A tightening through-hole 530 is opened, and the tightening piece 800 is screwed to the tightening lock hole 910 through the tightening through-hole 530. The guide roller 420 can be adjusted left and right by twisting the locking piece, and the connecting block 700 and the adjusting block 900 form a connecting cavity 4121, so that the adjusting end 4120 of the connecting rod 410 is fixed in the connecting cavity 4121. The position of the adjusting end 4120 of the connecting rod 410 in the connecting cavity 4121 is adjusted by the first adjusting block 500 and the second adjusting block 600, thereby changing the position relationship of the guide roller 420 relative to the first fixing piece 100. When the operator disassembles the guide roller 420 to replace the electrode, the position of the guide roller 420 can be changed by adjusting the first adjusting block 500 and the second adjusting block 600 according to the requirements of the battery electrode specifications, thereby meeting the requirements of battery electrode rollers of various specifications.
