A connecting mechanism is also provided on the top surface of the rubber block 17.

[0023] Preferably, the connecting mechanism includes: a positioning block 19, a positioning groove 20, a bolt 21 and a fixing hole 22.

[0033] Working principle: When using the electrode cold pressing and slitting tool with positioning function, start the motor 4 to drive the cold pressing roller 3 to rotate inside the first stand 2, so that when the electrode passes between the two cold pressing rollers 3, the cold pressing roller 3 will perform a cold pressing operation on the electrode, so that the electrode will be compressed and plastically deformed, so that the cold pressed electrode passes through the limiting roller 6 and the table body 1, so that the electrode can be moved to the knife groove 13, and then the electrode is connected to the set winding device. When the winding device is about to complete the winding of the electrode, it is necessary to perform a slitting operation on the electrode. At this time, start the second electric push rod 14 first, and let the movable end of the second electric push rod 14 drive the movable block 15 to slide in the slide groove 11, so that the movable block 15 can move downward with the pressure plate 16, so that the rubber block 17 at the bottom of the pressure plate 16 will contact the electrode on the top of the table body 1, so that by slightly squeezing By pressing the rubber block 17, the rubber block 17 will squeeze and fix the electrode of the cut part on the table body 1. At this time, the first electric push rod 8 is started, and the activity of the first electric push rod 8 drives the mounting plate 9 to move downward, so that one end of the slitting knife 12 at the bottom of the mounting plate 9 will pass through the through slot 18 and enter the knife slot 13. At this time, the slitting operation of the electrode can be completed, avoiding the displacement of the electrode when the slitting knife 12 contacts the electrode, thereby ensuring the flatness of the electrode cut. Secondly, when the rubber block 17 at the bottom of the pressure plate 16 is seriously aged and the use effect is poor, by screwing the bolt 21, one end of the bolt 21 is separated from the fixing hole 22, the positioning block 19 connected to the rubber block 17 can be separated from the positioning groove 20, so that the rubber block 17 can be removed, allowing the operator to maintain and replace the rubber block 17, thereby ensuring the use effect of the rubber block 17.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
