Description
Technical Field
[0001] This utility model relates to the field of slitting blade technology, and in particular to a high-precision slitting blade adjustment device. Background Technology
[0002] In the manufacturing of electronic cables, communication optical cables, fiber optic assemblies, and various tapes, slitting is a crucial precision cutting process. This process requires accurately dividing rolls of sheathing materials (such as aluminum foil, copper tape, insulating film, braided tubing, etc.) or cable sheaths into narrow strips of designed width. The precision and quality of slitting directly affect the electrical performance, mechanical strength, sealing performance, and appearance quality of the final product. One of the core elements for achieving high-quality slitting is the highly precise adjustment of the slitting blade installation angle and its long-term stable locking and retention capability.
[0003] Traditional slitting blade adjustment devices generally suffer from low precision, cumbersome operation, and poor stability, mainly in the following aspects: Coarse-grained adjustments are ill-suited for handling minute angular errors: Traditional adjustment methods often involve either integral movement or simple angle adjustment mechanisms. Integral movement requires moving the entire tool holder assembly, resulting in excessively large adjustment granularities that make it difficult to compensate for minute angular deviations. Furthermore, some simple angle adjustment mechanisms often have large adjustment increments (e.g., friction plates adjusting the depth of a single locking screw or simple locating pins), which cannot meet the demands of fine-tuning angles in modern high-precision slitting processes.
[0004] Unreliable locking and susceptibility to vibration: Existing adjustment devices often use friction clamping (such as multiple disc springs clamping friction plates) or a single screw to lock the blade angle. Under actual high-speed operation and long-term working conditions, the inherent vibration, impact, and fluctuations in cutting load can easily lead to insufficient locking force, causing the blade angle to slowly shift or momentarily loosen. This unstable "displacement" phenomenon significantly reduces slitting quality, leading to increased burrs on the cut, fluctuations in strip width, material waste, and accelerated blade wear or even chipping. Therefore, a high-precision slitting blade adjustment device is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.
[0006] Therefore, one objective of this utility model is to provide a high-precision slitting blade adjustment device to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.
[0007] To achieve the above objectives, one embodiment of the present invention provides a high-precision slitting blade adjustment device, including a main seat and a slider, wherein a transverse slider is fixedly connected to the back of the main seat; A central seat is fixedly connected to the top of the main seat, and an upper tooth seat is fixedly connected to the bottom of the central seat. Several serrated protrusions are fixedly connected to the edge of the bottom surface of the upper tooth seat. The main seat has a track inside, a guide block is movably connected in the track, a lifting seat is fixedly connected to the front of the guide block, and the lifting seat is movably connected inside the main seat. A rotating seat is movably connected to the center of the lifting seat, and a connector is fixedly connected to the bottom of the rotating seat. A blade is detachably connected to the inner side of the bottom end of the connector. A handle seat is fixedly connected to the top of the rotating seat, and a lower tooth seat is fixedly connected to the top of the handle seat. Several serrated protrusions are fixedly connected to the top edge of the lower tooth seat. The upper part of the lower tooth seat is joined with the upper tooth seat. Angle brackets are fixedly connected to both sides of the lifting seat. The angle brackets are fixed to the surface of the main seat by fasteners.
[0008] Preferably, in any of the above solutions, the main seat and the slider are connected by screws, and the slider is made of stainless steel.
[0009] The above technical solution is adopted: the main body of this device is a blade, which is mainly used to cut cable sheathing.
[0010] The main seat has a slider on its back, which allows the main seat to be adjusted to a straight position on the gantry frame and then locked in place with screws.
[0011] The blade can be rotated to adjust the angle, and the adjustment is precise. After adjustment, it is firmly matched and locked. The adjustment process is as follows: unscrew the fasteners. The angle bracket is now movably connected to the surface of the main seat. Operate the lifting seat and guide block to slide down. The lower tooth seat disengages from the upper tooth seat. At this time, the blade, rotating seat, connector, and lower tooth seat can be rotated as a whole. After adjusting to the appropriate angle, the lifting seat and guide block are raised to make the lower tooth seat move upward and mate with the upper tooth seat to lock the angle. The blade after rotation adjustment can better compensate for installation angle errors.
[0012] Preferably, in any of the above solutions, the lower part of the upper tooth seat is always matched with the lower tooth seat, and the guide block and the lifting seat can be freely raised and lowered after unlocking.
[0013] The above technical solution is adopted: Device composition: Main structure: The back of the main seat is fixed with a horizontal slider (made of stainless steel). The slider is installed on the gantry frame by bolts, and the straight position of the main seat can be adjusted laterally (Implementation method: After the main seat slides along the gantry frame guide rail to the target position, the slider is locked with bolts).
[0014] Angle locking unit: A center seat is fixed to the top of the main seat, and the center seat is connected to the upper gear seat. The bottom surface of the upper gear seat has a circular array of serrated protrusions. The lower gear seat is connected to the rotating seat through the handle seat, and its top surface serrations are precisely matched with those of the upper gear seat.
[0015] Blade adjustment mechanism: The bottom of the rotary table is connected to a connector, and the tungsten carbide blade is installed through the connector by a lock nut.
[0016] The rotating seat is nested in the center of the lifting seat, and the two sides of the lifting seat are fixed to the surface of the main seat by fasteners (internal hex screws) via corner brackets.
[0017] The bottom of the lifting seat is connected to a guide block, which slides with the track inside the main seat to form a vertical lifting path.
[0018] Preferably, the blade is made of tungsten steel, and the blade shaft is inserted into the connector and then tightened with a nut.
[0019] Preferably, the minimum adjustment angle of the lower gear seat is 0 degrees.
[0020] Preferably, in any of the above solutions, the fastener is a hex socket screw, the fastener is inserted into the corner bracket, and the fastener is threaded to the surface of the main seat.
[0021] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: This high-precision slitting blade adjustment device allows the blade to be rotated and adjusted at a precise angle. Once adjusted, the blade is securely locked in place. The adjustment process is as follows: unscrew the fasteners, at which point the angle bracket is movably connected to the main seat surface. Operate the lifting seat and guide block to slide down, disengaging the lower gear seat from the upper gear seat. At this point, the blade, rotating seat, connector, and lower gear seat can be rotated as a whole. After adjusting to the appropriate angle, the lifting seat and guide block are raised, causing the lower gear seat to move upward and engage with the upper gear seat, thus locking the angle. The blade adjusted by rotation can effectively compensate for installation angle errors.

The angle brackets 13 are fixed to the surface of the main seat 1 by fasteners 14.
[0028] Example 1: The main seat 1 and the slider 2 are connected by screws. The slider 2 is made of stainless steel. The lower part of the upper gear seat 4 always matches the lower gear seat 12. The guide block 6 and the lifting seat 7 can be freely raised and lowered after unlocking. The blade 10 is made of tungsten steel.

[0029] Example 2: The main body of this device is a blade 10, which is mainly used to cut cable sheathing. Device composition: Main structure: The back of the main seat 1 is fixed with a horizontal slider 2 (made of stainless steel).

Once adjusted, it is securely locked in place. The adjustment process is as follows: unscrew the fastener 14, at which point the angle bracket 13 is movably connected to the surface of the main seat 1. Operate the lifting seat 7 and guide block 6 to slide down, causing the lower gear seat 12 to disengage from the upper gear seat 4. At this point, the blade 10, rotating seat 8, connector 9, and lower gear seat 12 can be rotated as a whole. After adjusting to the appropriate angle, the lifting seat 7 and guide block 6 are raised, causing the lower gear seat 12 to move upward and engage with the upper gear seat 4, thus locking the angle. The blade 10 after rotational adjustment can better compensate for installation angle errors.
