Description

Technical Field

[0001] This utility model relates to the field of metal slitting equipment technology, specifically a metal slitting machine with adjustable spacing. Background Technology

[0002] A metal slitting machine is a device used in metal processing to cut wide metal coils into multiple narrow strips. Its structure mainly includes an uncoiler that carries the metal coil and controls the unwinding tension to ensure smooth material transport; a straightening unit that eliminates bending stress in the coil and improves cutting accuracy through a multi-roller straightening mechanism; and a slitting system. The mechanical blades within the slitting system are typically fixed-mount disc cutters.

[0003] A search revealed a metal slitting machine with adjustable spacing in patent application CN217253211U. The machine includes a combination mechanism, an adjustment mechanism, and a bonding mechanism. The adjustment mechanism is located on the upper left side of the combination mechanism, and bonding mechanisms are located on both sides of the adjustment mechanism. The adjustment mechanism includes a slitting roller, a groove, slitting blades, guide holes, and fasteners. The slitting roller has a groove in its center, and slitting blades are located on its outer wall, with guide holes on both sides of each blade. In this metal slitting machine with adjustable spacing, the slitting blades are wrapped around the slitting roller. The guide holes connect to the groove, and then the fasteners are extended to rotate and tighten the slitting blades, preventing them from wobbling or shifting during rotation. The rotation of the slitting roller drives several slitting blades to rotate, slitting the metal sheet. These slitting blades can move within the groove on the slitting roller, allowing for slitting of metal sheets to different sizes.

[0004] This metal slitting machine uses grooves on the outer wall of the slitting roller to allow the slitting blades to slide within the grooves, thus adjusting the spacing between the blades. However, this structure requires direct fixing of the blades during adjustment, and the blades are prone to longitudinal displacement when moving, making the adjustment neither safe nor quick. Utility Model Content

[0005] The purpose of this invention is to provide a metal slitting machine with adjustable spacing. By setting spacers on both sides of the slitting blade to clamp and limit the blade, the blade will not tilt during horizontal adjustment. The spacing can be adjusted by rotating the external top rod using an adjusting screw, thereby improving the adjustment speed.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a metal slitting machine with adjustable spacing, comprising a frame, a rotating roller rotatably connected inside the frame, a drive motor for driving the rotating roller to rotate installed inside the frame, two sets of rotating rollers, and a slitting blade set fixed on the outer wall of each rotating roller;

[0007] The slitting blade assembly includes a fixed slitting blade and a movable slitting blade. The outside of the rotating roller is provided with a fixing structure for fixing the fixed slitting blade to the outer wall of the rotating roller. An adjustment structure for adjusting the position of the movable slitting blade is provided between the fixed slitting blade and the movable slitting blade.

[0008] Preferably, the fixing structure includes a fixed spacer, the fixed slitting blade is clamped between two fixed spacers, the outer wall of the fixed spacer is provided with screw holes, and the fixed spacer is fixedly connected to the outer wall of the rotating roller by screws.

[0009] Preferably, the adjusting structure includes an adjusting screw, one end of which is threadedly connected to a top rod, and the other end of which is rotatably connected to one side of a fixed spacer.

[0010] Preferably, the adjustment structure further includes a movable spacer sleeve, which is sleeved on the outer wall of the rotating roller. The end of the top rod away from the adjusting screw is rotatably connected to one side of the movable spacer sleeve, and the movable slitting blade is clamped between two adjacent movable spacers sleeves.

[0011] Preferably, every two fixed spacers and the fixed slitting blade clamped between the two fixed spacers constitute a fixed blade group, and there are three fixed blade groups, which are located in the middle and at both ends of the rotating roller, respectively.

[0012] Preferably, each set of fixed blade assembly and movable spacer has two sets of adjusting screws, and the two sets of adjusting screws are equidistant.

[0013] Preferably, the outer wall of the rotating roller is provided with a keyway, and the inner cavities of the fixed slitting blade, the fixed spacer, the movable slitting blade, and the movable spacer are all provided with protrusions, which are located within the keyway.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model employs a dual clamping design with both fixed and movable spacers, enabling the slitting blade to be stably clamped at three points on the outer wall of the rotating roller. Specifically, two spacers clamp one blade, effectively preventing longitudinal offset during horizontal adjustment and ensuring the straight-line accuracy of the slitting operation. The fixed blade assembly, distributed in the middle and at both ends of the roller body, enhances the structural stability of the blade assembly.

[0016] 2. Employing a linkage structure between the adjusting screw and the push rod, the operator only needs to rotate the adjusting screw to move the movable spacer via threaded transmission, achieving continuous adjustment of the blade spacing. Compared to traditional adjustment methods that require disassembling fasteners, this structure improves the efficiency of spacing adjustment and supports online fine-tuning without disassembly.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a metal slitting machine with adjustable spacing, including a frame 1, a rotating roller 2 rotatably connected inside the frame 1, a drive motor 3 for driving the rotating roller 2 to rotate inside the frame 1, two sets of rotating roller 2, and a slitting blade set 4 fixed on the outer wall of each rotating roller 2.

[0024] The drive motor 3 drives two sets of symmetrically arranged rotating rollers 2 to rotate synchronously, and the slitting blades 4 on the two sets of rotating rollers 2 form a shearing action.

[0025] The slitting blade assembly 4 includes a fixed slitting blade 5 and a movable slitting blade 6. The outside of the rotating roller 2 is provided with a fixing structure 7 for fixing the fixed slitting blade 5 to the outer wall of the rotating roller 2. An adjustment structure 8 for adjusting the position of the movable slitting blade 6 is provided between the fixed slitting blade 5 and the movable slitting blade 6.

[0026] The fixed structure 7 includes a fixed spacer 701, the fixed slitting blade 5 is clamped between two fixed spacers 701, the outer wall of the fixed spacer 701 is provided with a screw hole 702, and the fixed spacer 701 is fixedly connected to the outer wall of the rotating roller 2 by screws.

[0027] The fixed spacer 701 is machined with high precision, and its axial length tolerance is controlled within ±0.02mm. A preload torque of 20-30 N·m is applied by engaging an M8 countersunk hexagonal screw with the threaded hole of the rotating roller 2. The two fixed spacers 701 prevent the fixed slitting blade 5 from tilting during horizontal movement.

[0028] The adjustment structure 8 includes an adjustment screw 801, one end of which is threadedly connected to a top rod 802, and the other end of which is rotatably connected to one side of a fixed spacer 701.

[0029] By adjusting the two sets of symmetrically arranged adjusting screws 801, the internal push rod 802 moves left and right after the adjusting screws 801 are rotated, which allows the movable spacer 803 to move axially.

[0030] The adjustment structure 8 also includes a movable spacer 803, which is sleeved on the outer wall of the rotating roller 2. The end of the top rod 802 away from the adjusting screw 801 is rotatably connected to one side of the movable spacer 803. The movable slitting blade 6 is clamped between two adjacent movable spacers 803.

[0031] The push rod 802 inside the adjusting screw 801 squeezes the movable spacer 803 tightly, and the two movable spacers 803 clamp the movable slitting blade 6.

[0032] Every two fixed spacers 701 and the fixed slitting blade group 4 clamped between the two fixed spacers 701 form a fixed blade group 9. There are three fixed blade groups 9, which are located in the middle and at both ends of the rotating roller 2, respectively.

[0033] Each set of fixed blade assembly 9 and movable spacer 803 has two sets of adjusting screws 801, and the two sets of adjusting screws 801 are equidistant.

[0034] By setting two sets of adjusting screws 801, the clamping force of the movable slitting blade 6 by the movable spacer 803 is made even.

[0035] The outer wall of the rotating roller 2 is provided with a keyway 10, and the inner cavities of the fixed slitting blade 5, the fixed spacer 701, the movable slitting blade 6 and the movable spacer 803 are all provided with protrusions 11, which are located in the keyway 10.

[0036] By setting the keyway 10 and the protrusion 11, the movable slitting blade 6 and the movable spacer 803 are limited to prevent rotation.

[0037] When in use, when it is necessary to adjust the slitting distance, manually rotate the adjusting screw 801 to screw out or in the top rod 802 connected to the internal thread of the adjusting screw 801, thereby changing the position of the movable spacer 803 and the movable slitting blade 6 as a whole, and realizing the position adjustment between the movable slitting blade 6 and the fixed slitting blade 5.

[0038] Compared to the traditional adjustment method that requires disassembling fasteners, operators can continuously adjust the blade spacing simply by rotating the adjusting screw 801, which can improve the efficiency of spacing adjustment.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
