AI Technical Summary
Existing material cutting equipment is difficult to adjust when adjusting the cutting size, has poor positioning accuracy, and requires secondary disassembly of the blades, which is time-consuming and labor-intensive.
The system employs a synchronous transmission feeding roller mechanism, a slitting mechanism, and a pushing mechanism, combined with a lifting assembly, a locking assembly, and a protective cover assembly. The slitting width and height are adjusted via a handwheel and a handle. A combination of angular contact bearings and deep groove ball bearings is used to stabilize the transmission. The protective cover assembly uses a spring support plate structure to simplify the adjustment process.
It enables rapid adjustment and stabilization of slitting dimensions, ensuring slitting accuracy, simplifying equipment operation, and reducing vibration and disassembly frequency in vibrating environments.

A slitting size adjustment mechanism comprising a worktable, a slitting mechanism, a synchronous transmission feed press roller mechanism, and a pushing mechanism, characterized in that, Two sets of synchronously driven feeding roller mechanisms are arranged horizontally on the workbench. A slitting mechanism and a pushing mechanism are arranged in the middle of the workbench between the two sets of synchronously driven feeding roller mechanisms. The slitting mechanism and the pushing mechanism are arranged longitudinally at intervals. The cutting mechanism includes a circular saw, an outer casing, a protective cover assembly, a lifting assembly, and a locking assembly. The upper end of the outer casing is fixedly connected to the bottom of the worktable, and the circular saw is connected above the outer casing. A circular saw drive mechanism is installed inside the outer casing, and the circular saw drive mechanism is connected to a motor installed in the machine housing via a synchronous belt. The motor drives the circular saw to rotate. A protective cover assembly is installed above the circular saw, and the outer casing is connected to the lifting assembly and the locking assembly. The lifting assembly can adjust the height of the circular saw, and the locking mechanism can lock the height of the circular saw.
2. A slitting size adjustment mechanism according to claim 1, wherein The drive assembly of the circular saw includes an outer sleeve, a main shaft, a timing belt, a bushing, and bearings. A main shaft is coaxially arranged inside the outer sleeve. The upper end of the main shaft is fixedly connected to the circular saw, and a drive wheel is fixedly installed at the lower end of the main shaft. The drive wheel is connected to a motor through the timing belt. The motor drives the main shaft to rotate, thereby driving the circular saw to rotate. A bushing is coaxially fitted between the main shaft and the outer sleeve. Bearings are arranged vertically and vertically on the inner circumference of the bushing between the main shaft and the bushing. The main shaft and the bushing are axially limited and fixed, while the main shaft can rotate flexibly coaxially within the bushing.
3. A slitting size adjustment mechanism according to claim 2, wherein, A deep groove ball bearing is installed between the lower part of the inner circumference of the bushing and the main shaft, and two opposing oblique ball bearings are mirror-arranged between the upper part of the inner circumference of the bushing and the main shaft.
4. A slitting size adjustment mechanism according to claim 2, wherein The lifting assembly includes a lifting handle, a lifting gear, and a rack. A rack is provided on the outer wall of the mirror side of the bushing, and a lifting gear is provided in the inner sleeve corresponding to the rack. The lifting gear meshes with the rack. The axle of the lifting gear extends to the outside of the chassis and is connected to a lifting handle. Rotating the lifting handle can drive the lifting gear to rotate.
5. A slitting size adjustment mechanism according to claim 1, wherein The locking assembly includes a locking handle, which is connected to an elliptical limiter.
6. A slitting size adjustment mechanism according to claim 1, wherein The pushing mechanism includes a trapezoidal nut, a pushing screw, a pushing handwheel, and a pushing baffle. The trapezoidal nut is fixedly connected to the workbench. A pushing screw is rotatably installed inside the trapezoidal nut. The pushing screw is arranged longitudinally.
