Description
[Technical Field]
[0001] This utility model relates to the field of hydrogen energy membrane electrode manufacturing, specifically a rolling cutter for cutting membrane electrodes. [Background Technology]
[0002] Currently, hydrogen energy membrane electrode cutting primarily employs die-cutting. This method involves manually fixing the die to the lower platform of a rocker arm press, then placing the raw material onto the die according to process requirements. A POM (Polymer Oxide Material) plate is then pressed on top of the material (this plate is a consumable part; it will leave cutting marks during the cutting process, and must be replaced if the marks become too dense). Finally, the upper rocker arm is moved above the POM plate, the start button is pressed down, and the die-cutting is complete. This die-cutting method for membrane electrodes has the following main drawbacks:
[0003] (1) The cutting method of the membrane electrode die cutting is complicated, with many cutting tools and complex cutting steps;
[0004] (2) Alignment is difficult, the alignment and cutting of the membrane electrode and the die takes a long time and the production efficiency is low;
[0005] (3) The quality of products cut by die-cutting is greatly affected by the product placement position, the pressure of the rocker arm, and the number of times the die-cutting is performed, which can easily lead to product quality accidents.
[0006] (4) High production cost, POM board is a vulnerable part with short replacement cycle and large loss;
[0007] Therefore, this cutting method is inefficient and cannot guarantee consistent product quality. Based on the above, providing a more scientific, efficient, and consistent cutting device would be of great significance. [Utility Model Content]

The pressure bearing 19 installed on the pressure roller 20 of the pressure mechanism is used to press the cutting roller 16 and provide cutting pressure to the cutting roller 16. The membrane electrode 22 to be cut enters between the cutting roller 16 and the cutting back roller 10.

The drive motor 6 drives the drive roller 5 and the cutting back roller 10 to rotate simultaneously.
[0012] Furthermore, the cutting roller mechanism includes a cutting roller gear 15 and a cutting roller 16. The cutting roller gear 15 is mounted on the cutting roller 16. A left fine-tuning bearing seat 13 is mounted on the left side end of the cutting roller 16, and a right fine-tuning bearing seat 14 is mounted on the right side end of the cutting roller 16.

The back roller gear 9 meshes with the cutting roller gear 15, thereby driving the cutting roller 16 and the cutting back roller 10 to rotate simultaneously.
[0013] Furthermore, a fine-tuning screw 12 is installed on the left fine-tuning bearing seat 13, and the left and right positions of the cutting roller 16 are adjusted by the fine-tuning screw 12 to correct the cutting offset error.
[0014] Furthermore, the clamping mechanism includes a clamping bearing 19 and a clamping roller 20. The clamping bearing 19 is installed on the left and right sides of the clamping roller 20. Bearing retaining rings 18 are installed on both sides of the clamping bearing 19. Sliding bearing seats 11-2 are installed at both ends of the clamping roller 20.
