Description

Technical Field

[0001] This utility model relates to equipment for producing thin ceramic fiber felt, and in particular to a thin ceramic fiber felt slitting device that is not prone to chipping. Background Technology

[0002] Thin ceramic fiber felt needs to be cut to the target width by a slitting device during the production process. Existing slitting blades are prone to collisions with other devices during installation, resulting in blade breakage. The fragments of the broken slitting blade can easily injure people nearby, posing a safety hazard. Summary of the Invention

[0003] The purpose of this invention is to provide a thin ceramic fiber felt slitting device with high safety and resistance to chipping.

[0004] The technical solution to achieve the purpose of this utility model is as follows:

[0005] A thin ceramic fiber felt slitting device that is not prone to blade breakage includes two frames and a first mounting rod and a second mounting rod disposed between the frames. The first mounting rod is positioned above the second mounting rod. Two slitting blades are mounted on the first mounting rod, and two slitting blocks corresponding to the slitting blades are mounted on the second mounting rod. Each slitting block is provided with a slitting groove, which is V-shaped. Each slitting blade includes a circular blade body and a cutting edge disposed on the outer edge of the blade body. The lowest point of the cutting edge extends into the slitting groove. The thickness of the cutting edge gradually decreases in the radial direction outward from the blade body. The width of the opening of the slitting groove is d, the thickness of the blade body is D, the ratio of d to D is 0.66-0.8, the width of the cutting edge in the radial direction of the blade body is H, and the depth of the slitting groove in the radial direction of the blade body is h, where H is less than h.

[0006] With the above structure, during the assembly of the slitting device, the cutting edge of the slitting knife extends into the slitting knife groove, and the cutting edge does not contact the slitting block to cut the ceramic fiber station between the slitting knife and the slitting block. The cutting edge is not easily damaged. Even if the slitting knife accidentally comes into contact with the slitting block during assembly, the thicker part of the cutting edge that is closer to the blade body will contact the opening of the slitting knife groove, avoiding the occurrence of damage or chipping of the thinner part of the cutting edge due to force. This utility model can reduce the occurrence of chipping of the slitting knife due to accidental collision, has high safety, and increases the service life of the slitting knife.

[0007] Preferably, in order to further protect the blade, a rubber gasket is provided at the opening of the slitting groove.

[0008] Preferably, to facilitate adjustment of the width of the cut fiberglass mat, both ends of the first and second mounting rods are rotatably connected to the frame. The first mounting rod is provided with a first threaded section and a second threaded section, the threads of which are opposite in direction. Each of the first and second threaded sections is threadedly connected to one of the two slitting blades. The second mounting rod is provided with a third threaded section and a fourth threaded section, the threads of which are opposite in direction. Each of the third and fourth threaded sections is threadedly connected to one of the two slitting blocks. The threads of the first and third threaded sections are opposite in direction, and the threads of the second and third threaded sections are opposite in direction. A first guide rod is provided below the first mounting rod, passing through the two slitting blades. The slitting blades slide against the first guide rod. The first mounting rod is fixedly connected to the frame at both ends. A second guide rod is provided below the second mounting rod. The second guide rod passes through two slitting blocks. The slitting blocks slide with the second guide rod. The two ends of the second guide rod are fixedly connected to the frame. A first driven wheel is provided at the end of the first mounting rod. A second driven wheel is provided at the end of the second mounting rod below the first driven wheel. A motor mounting plate is provided on the outside of the first driven wheel. A motor is fixed on the motor mounting plate. The motor has a rotating shaft. A drive wheel is fixedly mounted on the rotating shaft. The drive wheel is located between the first driven wheel and the second driven wheel and meshes with both the first driven wheel and the second driven wheel at the same time. In this way, the position of the slitting blade and the slitting blocks can be adjusted simultaneously by the motor. When the slitting blade moves left and right, the corresponding slitting blocks also move synchronously, avoiding the collision between the blade edge and the slitting groove of the slitting blade and causing blade breakage.
