TECHNICAL FIELD
[0001] The utility model belongs to foil cutting knife adjusting technical field, specifically a new type sodium ion battery foil cutting upper and lower knife adjusting device. BACKGROUND
[0002] In the production process of sodium ion battery, cutting pole piece as a key process is concerned, and good pole piece cutting effect plays a vital role in the quality of battery. As a very important component of cutting device, cutting knife is extremely important. The installation of cutting knife and cutting knife holder is also very important. A good installation method can avoid damage to the cutting knife and reduce the rejection rate of the cut pole piece. The cutting knife is divided into upper knife and lower knife, which are installed on the upper and lower knife shafts, respectively, and fixed on the knife seat by the square blocks on both sides of the knife shaft.
[0003] A patent with publication number CN117584189A discloses a capacitor positive and negative material and battery positive and negative sheet material cutting device and method, relating to capacitor aluminum foil cutting technology, comprising a knife mold base and two knife shafts arranged above the knife mold base. The upper end of the knife mold base is provided with a group of knife mold supports on both sides, and each group of knife mold supports has two. The present application realizes the cutting of aluminum foil by rotating the upper and lower knife shafts. Before cutting, the knife mold is adjusted by the front and rear knife mold pressure rollers on the blocking ring on the knife shaft. The upper and lower knife suction ports are rolled and cut, and the knife blade is flat. This structure can avoid the material entering the knife gap during rolling, and can also guide the cut aluminum / foil strip after cutting to better separate the cut aluminum / foil strip. The specific position of the knife mold pressure roller can be adjusted according to the actual adjustment requirements, making the adjustment of the knife mold pressure roller position more accurate, and better adjusting the blocking ring in the up-down and left-right angles.
[0004] At present, in the prior art, the knife shaft of the cutting knife is usually made of high-strength steel to ensure that it does not deform during operation. The cutting mechanism is composed of upper shaft, lower shaft, left and right fixed seat, base, cutting knife, etc. The upper and lower cutting knives are installed on the upper and lower shafts, respectively, and the shear force generated by rotation separates the pole piece. Therefore, the upper and lower knives need to overlap. The existing installation method is to install the cutting knife on the knife shaft, then manually lift it to the knife seat, and then manually adjust the screw bolts on the left and right fixed seats to adjust the gap between the upper and lower knives. It takes a lot of time, and if not careful, the upper and lower knives will be damaged at the same time.

[0031] When working, the upper cover plate 4 is opened together with the bolt 1 when installing the knife shaft, and the lower axle fixed seat 102 is first installed in the middle of the right and left fixed plates 2 and 3. After the lower axle is installed, the high-strength spring 105 is fixedly installed in the middle of the lower axle fixed seat 102, which has an area for placing the spring. After the high-strength spring 105 is installed, the left and right pad blocks 103 and 104 are tightly attached to the right and left fixed plates 2 and 3. After the pad blocks are installed, the upper axle is then placed after being aligned with the upper axle fixed seat 101. After the upper and lower axles are installed, the previously removed bolt 1 and the upper cover plate 4 are installed. After the left and right bolts 1 are tightened, the bolt 1 is adjusted, the screw is pressed down, the upper axle fixed seat 101 moves downward, and the upper axle is supported by the high-strength spring 105 and does not directly fall, but slowly descends. The left and right pad blocks 103 and 104 serve as limiters, and when the bolt 1 cannot be moved, it indicates that the upper and lower positions have been adjusted to the appropriate position, and the distance between the upper and lower axles is determined.
