[0023] Please see Figure 1-4As shown, this utility model is a nitrocellulose membrane slitting device. When the nitrocellulose membrane is guided and transported by the rotating roller 1, it is slitted by a row of cutting ring blades 3 installed on the slitting roller 4. The blades of the cutting ring blades 3 are close to the rotating roller 1, and the rotation directions of the cutting ring blades 3 and the rotating roller 1 are opposite.

[0024] Both ends of the rotating roller 1 and the slitting roller 4 are stepped ends 401, which are installed in the bearing housing 2. Specifically, the stepped ends 401 are fitted into the bearings of the bearing housing 2. The rotating roller 1 and the slitting roller 4 are driven by two independent drive devices, and the power source of the drive devices is an electric motor.

[0025] A row of equally spaced concave rings 402 are provided on the slitting roller 4. A transverse groove 404 is provided on the slitting roller 4 in the axial direction. The transverse groove 404 connects the concave rings 402. Notches 403 are provided on the two ring walls of the concave rings 402.

[0026] Both the stepped clamping ring 5 and the limiting ring 6 have locking blocks 603 inside. The cutting ring blade 3 is held in the concave ring 402 by the stepped clamping ring 5 and the limiting ring 6. The locking blocks 603 are engaged with the notch 403. The stepped clamping ring 5 and the limiting ring 6 form a clamp. The clamp is used to hold the cutting ring blade 3. During installation, the locking blocks 603 of the stepped clamping ring 5 move along the transverse groove 404 to the concave ring 402. Then, the stepped clamping ring 5 is rotated so that the locking blocks 603 face the notch 403. The cutting ring blade 3 is engaged on the stepped clamping ring 5.

[0027] Additionally, the limiting ring 6 includes a second plate ring 605, a locking block 603 is disposed on the inner arc surface of the second plate ring 605, the second plate ring 605 is provided with a clamping arc plate 602, the clamping arc plate 602 abuts against the cutting ring blade 3, the limiting ring 6 includes a first half ring 601, the ends of the first half ring 601 and the second plate ring 605 are both provided with ear plates 604, and the first half ring 601 and the second plate ring 605 are connected by bolts.

[0028] The cutting ring blade 3 is then clamped and fixed by bolting the limiting ring 6. The limiting ring 6 can be made of polyoxymethylene plastic, which ensures high rigidity and high hardness while having excellent creep resistance and elastic recovery ability.

[0029] Install the appropriate number of cutting ring blades 3 according to the cutting requirements. In addition, for cutting nitrocellulose membranes of different sizes, three concave rings 402 with a spacing of 25mm, 18mm or 20mm respectively need to be designed to load the cutting ring blades 3.
