Abstract
The invention discloses a cutting knife of a lithium battery anode plate and cathode plate pair-roll mill. The parting tool comprises knife rest fixing rods and a knife rest fixing device arranged on the knife rest fixing rods. A perpendicular knife rest is arranged on the lower portion of the knife rest fixing device. An upper knife wheel and a lower knife wheel are arranged on the perpendicular knife rest in sequence. The upper knife wheel is fixed on the perpendicular knife rest through a shaft of the upper knife wheel, and the lower knife wheel is fixed on the perpendicular knife rest through a shaft of the lower knife wheel. The lower knife wheel is connected with an adjustable-speed motor. The lower knife wheel contacts with the upper wheel. The adjustable-speed motor drives the lower knife wheel to rotate. The lower knife wheel drives the upper knife wheel to rotate relative to the lower knife wheel. Due to the fact that the upper knife wheel and the lower knife wheel are all fixed on one knife rest, the upper knife wheel and the lower knife wheel are an integral whole. Therefore, in the process of production, the upper knife wheel and the lower knife wheel just need adjusting well, materials just need to be replaced, knifes do not need regulating again, and just the whole knife rest needs moving. Moreover, the upper knife wheel and the lower knife wheel are convenient to replace.
Description
Technical Field
The invention relates to a pair-roller machine cutter for trimming redundant pole piece scraps of positive and negative pole pieces of a lithium battery before continuous pair roller.
Background
The general structure of the cutter of the roll mill in the prior art is as follows: 1: the lower cutter wheel shaft is carried by a motor. Two blades (one on the left and the right) 2 are arranged on the lower cutter wheel shaft: the upper knife wheel is arranged on an upper knife wheel frame which is composed of a bracket. Two cylinders.
Wherein, one cylinder can make the upper knife flywheel move up and down, and one cylinder can make the upper knife flywheel move left and right.
And during working, the lower cutter wheel is adjusted to the position of the pole piece to be trimmed, and then the upper cutter wheel and the lower cutter wheel are adjusted (the cutting depth of the upper cutter wheel and the lower cutter wheel and the gap between the upper cutter wheel and the lower cutter wheel are adjusted) so that the upper cutter wheel and the lower cutter wheel can cut off the copper foil or the aluminum foil.
And after the upper knife flywheel and the lower knife flywheel are adjusted, the motor can carry the lower knife flywheel to rotate. The lower knife flywheel can carry the upper knife flywheel to rotate by rotating. Therefore, the upper and lower cutter wheels form a hob which can roll and cut the edge material of the pole piece.
The technical defects of the prior art are as follows:
1: the upper cutter wheel and the lower cutter wheel are separated, and the lower cutter wheel is moved to a position where the material scraps are cut and fixed during operation. Then the upper knife wheel frame is moved to make the upper knife wheel and the lower knife wheel matched well. This is inconvenient, i.e. it is time consuming to adjust each time another roll of material (pole piece) is replaced.
2: the cutter is inconvenient to adjust, namely the contact depth of the upper cutter wheel and the lower cutter wheel is adjusted by adjusting the upper position and the lower position of an upper adjusting piece and a lower adjusting piece of the upper cutter wheel. And the upper and lower adjusting parts of the upper cutter wheel are fixed by 1M 6 screw, so that the adjustment is inconvenient. It is difficult to adjust to the proper position. The adjustment is easy to loose.
3: the upper knife wheel frame is unstable and weak, namely the upper knife wheel shaft is arranged on the rod of an upper knife wheel cylinder (the cylinder with the diameter of 20 x 5). The upper knife wheel frame part is unstable because the upper knife wheel cylinder is connected with the other cylinder of the upper knife wheel through 1M 4 screw. The upper knife flywheel can be shaken by hands, so that the upper knife flywheel and the lower knife flywheel are not well matched, and faults often occur.
4: the lower cutter wheel is damaged and is inconvenient to replace. The lower cutter wheel is arranged on the lower cutter wheel shaft. The lower cutter wheel shaft is firstly detached when the cutter wheel is detached. And the lower cutter wheel shaft is provided with a bearing, a gear and the like, so that the lower cutter wheel shaft is not easy to disassemble.
