Description

Technical Field

[0001] This utility model relates to an adjustable slitting tool structure and belongs to the technical field of slitting equipment. Background Technology

[0002] In the industrial production process of aluminum foil, the slitting process is one of the core processing steps. It mainly uses the cooperation of slitting rollers and slitting cutters to cut wide aluminum foil rolls into narrow aluminum foil strips of various specifications to meet the needs of subsequent deep processing and use.

[0003] Currently, the commonly used aluminum foil slitting equipment in the industry mainly adopts a blade structure in which a slitting shaft is set on one side below the slitting roller, and at least one circular blade that can be adjusted in position axially and rotated around the slitting shaft for adjustment and locking. To meet the slitting requirements of aluminum foil of various specifications, slitting grooves that precisely match the circular blade are evenly opened on the surface of the slitting roller. However, due to the process requirements of narrow-width aluminum foil slitting, the spacing between adjacent slitting grooves is extremely small, resulting in a thin dividing ring structure between adjacent slitting grooves and low structural strength.

[0004] Existing slitting cutter structures have significant technical defects. Traditional circular blades can only achieve coarse axial position adjustments over a wide range, failing to perform high-precision fine-tuning. During actual production and debugging, misalignment of the circular blades easily occurs, preventing them from accurately engaging within the slitting groove of the slitting roller. The circular blades directly rub and compress against the thin dividing ring of the slitting roller, causing scratches, chipping, and deformation on the roller surface, significantly reducing its lifespan, increasing equipment maintenance costs and downtime, and leading to burrs, off-center cutting, and breakage at the aluminum foil slitting edges. This affects the processing accuracy and product yield of the finished aluminum foil, failing to meet the demands of high-precision, high-stability aluminum foil slitting production. Utility Model Content

[0005] This invention provides an adjustable slitting tool structure to solve the problems existing in the background art.

[0006] This utility model relates to an adjustable slitting tool structure, including a slitting shaft disposed below one side of a slitting roller, and at least one set of slitting tool assemblies disposed on the slitting shaft. Both ends of the slitting shaft are rotatably mounted on a frame and one end is connected to a flip-drive locking mechanism. The slitting tool assembly includes a transverse adjustment locking mechanism disposed on the slitting shaft that can be adjusted and locked axially. A transverse fine-tuning self-locking mechanism is connected to the transverse adjustment locking mechanism. A longitudinal fine-tuning self-locking mechanism is connected above the transverse fine-tuning self-locking mechanism. A tool holder plate is connected to the longitudinal fine-tuning self-locking mechanism. A mounting shaft is fixed on the upper part of the tool holder plate, and a detachable circular blade is fixed on the mounting shaft.

[0007] As a preferred embodiment, the lateral adjustment and locking mechanism includes a movable slide rail fixed to the slitting shaft, a movable slider on the slide rail, a movable plate fixed to the top of the movable slider, and a locking plate fixed to the bottom of the movable plate. The lower end of the locking plate extends to the lower part of the slide rail and is threadedly connected to a locking bolt. The movable slide rail and movable slider work together to achieve a wide range of axial sliding coarse adjustment of the blade, providing a large adjustment stroke and wide compatibility with various specifications, allowing for quick initial position adjustment of multi-specification aluminum foil slitting. Combined with the locking bolt on the locking plate, rapid locking can be achieved.

[0008] As a preferred embodiment, the lateral fine-tuning self-locking mechanism includes a lateral fine-tuning slide rail fixed on a movable slide plate, a lateral fine-tuning slider on the slide rail, and a lateral fine-tuning screw connected to the lower center of the slider via a nut. The screw is rotatably mounted on the movable slide plate. This screw-nut drive achieves lateral micro-feed adjustment, providing high transmission accuracy and uniform feed, enabling precise lateral fine-tuning of the blade and compensating for positional deviations caused by coarse adjustments. Simultaneously, the screw and nut possess mechanical self-locking properties, automatically locking the position after fine-tuning to maintain stable lateral alignment accuracy of the blade.

[0009] As a preferred embodiment, the longitudinal fine-tuning self-locking mechanism includes a longitudinal fine-tuning slide rail fixed to the top of the transverse fine-tuning slider. A longitudinal fine-tuning slider is mounted on the slide rail, and a longitudinal fine-tuning screw is connected to the lower middle part of the slider via a nut. The two ends of the screw are rotatably mounted on the ends of the slide rail via mounting plates. This independent longitudinal screw fine-tuning structure enables precise adjustment of the blade's longitudinal position, overcoming the limitation of traditional blades that can only be adjusted in one direction. It achieves high-precision alignment in both transverse and longitudinal directions, adapting to the working conditions of narrow-pitch slitting rollers and thin dividing rings.

[0010] As a preferred embodiment, a Z-shaped connecting plate is fixed to the top of the longitudinal fine-tuning slider, and the outer end of the connecting plate is fixed to the tool holder plate.

[0011] As a preferred embodiment, one end of both the longitudinal and transverse fine-tuning screws is fixed with a fine-tuning wheel, which facilitates the rotation of the longitudinal and transverse fine-tuning screws.

[0012] As a preferred embodiment, limit discs are fitted on the mounting shafts on both sides of the circular blade. The left limit disc is fixed on the mounting shaft, while the right limit disc is movably fitted onto the mounting shaft. A clamping nut with a thread on the outside of the right limit disc is installed on the mounting shaft. The clamping and fixing structure with double limit discs and clamping nuts can accurately limit and clamp the circular blade axially. At the same time, the detachable locking structure is easy to disassemble and assemble, which facilitates blade grinding, replacement and maintenance, and effectively reduces equipment operation and maintenance costs.

[0013] As a preferred embodiment, the flip-drive locking mechanism includes a worm gear reducer connected to one end of the slitting shaft. A support is rotatably mounted on the outer end of the worm shaft of the worm gear reducer, and the support is fixed to the frame. A locking bolt for locking the worm shaft is provided on the outer side wall of the support, and a rotating handwheel is fixed to the outer end of the worm shaft. The worm gear reducer has a self-locking characteristic, enabling multi-angle flip-drive adjustment and passive self-locking of the slitting shaft, adapting to the slitting angle requirements of aluminum foils of different thicknesses. Combined with the end fixing bolt, it forms a double mechanical locking mechanism, maintaining a constant slitting angle.

[0014] As a preferred embodiment, the slitting roller is fitted with support sleeves at both ends, which are fixed to the frame. The top inner end of each support sleeve has a semi-circular pick-and-place notch, and a semi-circular pressure sleeve is located at the pick-and-place notch. The pressure sleeve has clamping bolts. Both the support sleeve and the pressure sleeve have limiting annular grooves on their inner walls, and the outer walls at both ends of the slitting roller have limiting bosses that mate with the limiting annular grooves. This combined support sleeve and pressure sleeve enveloping structure provides stable support and radial limiting for the slitting roller. Combined with the engaging structure of the limiting annular grooves and limiting bosses, it effectively restricts the axial movement and radial runout of the slitting roller. The top pick-and-place notch structure facilitates the disassembly and maintenance of the slitting roller, improving equipment maintenance convenience while ensuring operational accuracy.

[0015] This utility model has the following beneficial effects: This utility model features a hierarchical adjustment structure. A lateral adjustment locking mechanism enables a wide range of coarse axial positioning of the blade. A lateral fine-tuning self-locking mechanism and a longitudinal fine-tuning self-locking mechanism enable high-precision fine-tuning and locking in the lateral and longitudinal directions, respectively. Combined with a flip-drive locking mechanism, it solves the problems of traditional blades being unable to fine-tune and having poor alignment accuracy. This allows the circular blade to accurately extend into the slitting groove of the slitting roller, effectively preventing the blade from colliding and rubbing against the thin dividing ring of the slitting roller, thus avoiding damage to the slitting roller and reducing equipment maintenance costs and downtime losses.

[0019] Example 1, as Figures 1 to 4 As shown, this utility model is an adjustable slitting tool structure, including a slitting shaft 5 disposed below one side of the slitting roller 3. The slitting shaft 5 is provided with at least one set of slitting tool assemblies. Both ends of the slitting shaft 5 are rotatably mounted on the frame 1 and one end is connected to a flip-drive locking mechanism. The slitting tool assembly includes a transverse adjustment locking mechanism disposed on the slitting shaft 5 that can be adjusted and locked along the axial direction. A transverse fine-tuning self-locking mechanism is connected to the transverse adjustment locking mechanism. A longitudinal fine-tuning self-locking mechanism is connected above the transverse fine-tuning self-locking mechanism. A tool holder plate 16 is connected to the longitudinal fine-tuning self-locking mechanism. A mounting shaft 18 is fixed on the upper part of the tool holder plate 16.

[0020] Before starting work, first, according to the aluminum foil slitting specifications, release the locking mechanism of the lateral adjustment mechanism, push the blade holder plate 16 to move quickly along the axial direction to complete the axial coarse positioning of the circular blade 6, and lock the lateral adjustment mechanism after moving it to the vicinity of the required adjustment position; then adjust the flip angle of the slitting shaft 5 by flipping the driving locking mechanism so that the circular blade 6 is close to the slitting roller 3, and then complete the high-precision fine adjustment of the blade in the lateral and longitudinal directions by using the lateral fine adjustment self-locking mechanism and the longitudinal fine adjustment self-locking mechanism respectively, so that the circular blade 6 is accurately aligned with the slitting groove on the surface of the slitting roller 3; start the equipment to perform high-precision aluminum foil slitting operation.

[0021] In Example 2, based on Example 1, the lateral adjustment locking mechanism includes a movable slide rail 4 fixed on the cutting shaft 5.

Then, the clamping nut 19 is unscrewed, the right limiting disc is removed, and then the circular blade 6 is removed for replacement.

[0027] The flip-drive locking mechanism includes a worm gear reducer 11 connected to one end of the slitting shaft 5.
