Description

Technical Field

[0001] This utility model relates to the field of metal slitting machine technology, and in particular to an ultra-thin metal strip longitudinal shearing and slitting machine unit. Background Technology

[0002] An ultra-thin metal strip slitting unit has wide applications in precision machining fields such as electronics, automobile manufacturing, and home appliances. Its core function is to longitudinally slit metal strips with a thickness of micrometers into strips of a specific width. As downstream industries continue to increase their requirements for the precision of metal parts, higher challenges are being placed on the slitting accuracy, changeover efficiency, and strip conveying stability of slitting equipment. In particular, for ultra-thin strips with a thickness of ≤0.1mm, how to achieve rapid adjustment of blade distance and adaptive compensation for tension fluctuations during high-speed slitting has become a key direction for industry technology optimization.

[0003] In the existing technology, slitting machines typically use a fixed rigid guide roller group and a cutter shaft spacing adjustment structure driven by a screw drive or hydraulic cylinder. The guide roller group is installed on the frame by a fixed bracket. When the strip is conveyed, the rigid roller surface constrains the travel path. The cutter spacing adjustment requires manual input of parameters through the operating table. The screw driven by the motor or hydraulic cylinder pushes the cutter shaft to move along the slide rail. The spacing adjustment is achieved through feedback from the displacement sensor.

[0004] However, the traditional structure mentioned above cannot simultaneously achieve rapid and precise adjustment of the slitting blade distance and adaptive tension guidance during strip conveying. On the one hand, screw or hydraulic adjustment requires multiple steps such as "stopping the machine - parameter input - mechanical adjustment - centering calibration", which takes a long time for each changeover, and manual operation is prone to causing large errors in blade parallelism. On the other hand, fixed rigid guide rollers cannot dynamically compensate for lateral offset or wrinkles caused by tension fluctuations during high-speed strip conveying. This often leads to strip width deviation due to the strip edge deviating from the center of the slitting blade, and may even cause strip breakage accidents, seriously affecting production efficiency and finished product yield. Therefore, an ultra-thin metal strip slitting unit is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an ultra-thin metal strip slitting machine, which aims to improve the problems of long time consumption and low accuracy in the prior art when manually adjusting the blade spacing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A slitting machine for ultra-thin metal strip includes a base plate, with support plates fixedly connected to both sides of the top of the base plate. A guide assembly and an adjustment assembly are arranged between the support plates, with the adjustment assembly located on the side of the guide assembly.

[0008] The adjustable distance assembly includes a guide plate, both sides of which are fixedly connected to the sidewalls of the support plate. Multiple sliders are slidably connected to the outer wall of the guide plate. A fixing block is fixedly connected to the top side of one slider. A hydraulic rod is provided on the side of the fixing block. The outer wall of the hydraulic rod is fixedly connected to the inside of the support plate on one side. The output end of the hydraulic rod is fixedly connected to the sidewall of the fixing block. Each slider has a connecting arm one and a connecting arm two rotatably connected to its top. The other end of each connecting arm one is rotatably connected to the other end of each connecting arm two. A knife holder is fixedly connected to the bottom of each slider. A slitting knife is rotatably connected inside the knife holder.

[0009] As a further description of the above technical solution:

[0010] The bottom of the slitting knife is provided with a bearing roller, both ends of which are rotatably connected to the side wall of the support plate. A power roller is provided on the side of the slitting knife, one end of which is rotatably connected to the side wall of the support plate.

[0011] As a further description of the above technical solution:

[0012] A drive motor is provided at the other end of the power roller. Multiple fixing plates are fixedly connected to the outer wall of the drive motor. The side wall of the fixing plate is fixedly connected to the side wall of the support plate. The output end of the drive motor is fixedly connected to the side wall of one end of the power roller.

[0013] As a further description of the above technical solution:

[0014] A control console is provided on the side of the drive motor, and the side wall of the control console is fixedly connected to the side wall of the support plate.

[0015] As a further description of the above technical solution:

[0016] The guiding assembly includes multiple guide rollers, which are distributed in a zigzag pattern between the support plates, and each guide roller is rotatably connected to a rotating seat at both ends.

[0017] As a further description of the above technical solution:

[0018] The sidewalls of the support plate are provided with multiple sliding grooves, the positions of which are consistent with the positions of the guide rollers, and the rotating seats are slidably connected inside the sliding grooves.

[0019] As a further description of the above technical solution:

[0020] Each rotating seat is equipped with a buffer spring at its bottom. One end of each buffer spring is fixedly connected to the inner wall of the slide groove, and the other end of each buffer spring is fixedly connected to the bottom of the rotating seat.

[0021] As a further description of the above technical solution:

[0022] Each of the rotating seats on one side is fixedly connected to a connecting seat, and each connecting seat is provided with an electric actuator at its bottom. The outer wall of each electric actuator is fixedly connected to the side wall of the support plate, and each electric actuator output end is fixedly connected to a push rod. The top of each push rod is fixedly connected to the bottom of the connecting seat.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the output end of the hydraulic rod first pushes the fixed block to move, which in turn drives the slider on one side to move, causing the connecting arms one and two at the top of the slider to rotate. Through the cooperation of multiple sets of connecting arms, the motion is transmitted to the other sliders, causing them to move inward or outward, thereby driving the knife holder and slitting knife to move, achieving the effect of rapid adjustment of the slitting knife spacing. This solves the problem of long time consumption and low accuracy in traditional manual adjustment of knife spacing, and improves slitting efficiency and changeover flexibility.

[0025] 2. In this utility model, when the metal strip shifts laterally or wrinkles due to tension fluctuations, the electric pusher drives the push rod to move, thereby causing the connecting seat to slide in the groove. The guide roller moves accordingly, achieving the effect that the guide roller can automatically compensate for the offset with the tension of the metal strip. This solves the problem that traditional rigid guides easily cause the strip to shift and wrinkle, and improves the slitting accuracy and conveying stability. Attached Figure Description

[0033] 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.

[0034] Reference Figures 1-3 The present invention provides an embodiment of an ultra-thin metal strip slitting machine unit, including a base plate 1, which is made of steel plate with a large thickness to ensure the stability of the entire unit. Support plates 2 are fixedly connected to the top two sides of the base plate 1 by welding. The support plates 2 are made of channel steel and have high strength and rigidity to provide support for other components. A guide component and an adjustment component are provided between the support plates 2. The guide component is used to guide the conveying direction of the metal strip, and the adjustment component is used to adjust the spacing of the slitting blades 15. The adjustment component is located on the side of the guide component.

[0035] The adjustable distance assembly includes a guide plate 8, which is made of stainless steel with a smooth surface. Both sides of the guide plate 8 are bolted to the sidewalls of the support plate 2 to guide the sliding of the slider 9. Multiple sliders 9 are slidably connected to the outer wall of the guide plate 8. The sliders 9 are made of wear-resistant engineering plastic and have a high precision fit with the guide plate 8 to ensure smooth sliding. A fixing block 10, also made of engineering plastic, is fixedly connected to the top side of one slider 9. This fixing block 10 connects the hydraulic rod 11 to the slider 9. The hydraulic rod 11, which is existing technology and will not be described in detail here, is used to move the slider 9. The hydraulic rod 11 provides power and is fixedly connected to the outer wall of a support plate 2 on one side. The output end of the hydraulic rod 11 is fixedly connected to the side wall of the fixed block 10. Each slider 9 has a connecting arm 12 and a connecting arm 23 rotatably connected to its top via a pin. The connecting arms 12 and 23 are made of alloy structural steel and have high strength and toughness. The other end of each connecting arm 12 is rotatably connected to the other end of each connecting arm 23 via a pin, together forming a linkage mechanism for transmitting motion and force. Each slider 9 has a tool holder 14 fixedly connected to its bottom via bolts. The tool holder 14 is made of high-strength alloy steel and is used to install slitting blades 15. The tool holder 14 has internal components... A slitting blade 15, made of hard alloy, is rotatably connected via bearings. Its sharp cutting edge is used to cut ultra-thin metal strips into slits. A support roller 7, made of stainless steel and hardened, is located at the bottom of the slitting blade 15. Both ends of the support roller 7 are rotatably connected to the side wall of the support plate 2 via bearings, supporting the metal strip and assisting the slitting blade 15 in cutting. A power roller 6, made of alloy steel, is located on the side of the slitting blade 15. One end of the power roller 6 is rotatably connected to the side wall of the support plate 2 via a bearing, and the other end is equipped with a drive motor 4, a three-phase asynchronous motor that provides stable power output. The drive motor 4 is existing technology and will not be described in detail here. Multiple fixing plates 5 are fixedly connected to the outer wall of the drive motor 4 by bolts. The side wall of the fixing plate 5 is fixedly connected to the side wall of the support plate 2 for fixing the drive motor 4. The output end of the drive motor 4 is fixedly connected to one side wall of the drive roller 6 by a coupling to transmit power to the drive roller 6. A control console 22 is set on the side of the drive motor 4. The outer shell of the control console 22 is made of cold-rolled steel plate and integrates a control system for operators to control the unit and set parameters. The control console 22 is existing technology and will not be described in detail here. The side wall of the control console 22 is fixedly connected to the side wall of the support plate 2 by bolts.

[0036] Specifically, when using this ultra-thin metal strip slitting unit, the operator first passes one end of the metal strip through the guide rollers 16, forming a zigzag guide path between the guide rollers 16. During this process, the metal strip is in close contact with the roller surface of the guide rollers 16. Due to the surface roughness of the guide rollers 16 and the tension of the metal strip itself, the frictional coupling between the metal strip and the roller surface of the guide rollers 16 is increased, so that the metal strip can be stably conveyed in the predetermined direction. After being guided by the guide rollers 16, the metal strip passes through the position of the slitting knife 15, which cuts the metal strip into strips. After that, the operator fixes the slitting metal strip on the outer wall of the carrying roller 7. At this time, the operator starts the drive motor 4 through the control console 22. The output end of the drive motor 4 drives the power roller 6 to rotate through the coupling. There is friction between the power roller 6 and the metal strip. The rotation of the power roller 6 drives the metal strip to wind through friction, and at the same time pulls the unslitting metal strip to move along the direction of the guide assembly, so as to realize the continuous slitting operation of the metal strip.

[0037] When the spacing of the slitting blades 15 needs to be adjusted to accommodate slitting operations of different widths, the operator inputs the corresponding control commands on the control panel 22. The control panel 22 transmits the command signals to the hydraulic rod 11. Under the pressure of hydraulic oil, the piston rod of the hydraulic rod 11 moves towards the fixed block 10. If the spacing of the slitting blades 15 needs to be reduced, it extends; if the spacing of the slitting blades 15 needs to be increased, it retracts. When the piston rod extends, it pushes the fixed block 10 to move. The displacement of the fixed block 10 causes the slider 9, which is fixedly connected to it, to slide along the guide direction of the guide plate 8 on the outer wall of the guide plate 8. The sliding of the slider 9 causes the connecting arm 12 and connecting arm 13, which are rotatably connected to it by a pin at their top, to move. The rotation is transmitted through the pins to the connecting arms 12 and 13 on the top of another slider 9. This rotation, caused by the connecting arms 12 and 13 connected to each other via the pins, allows the movement to occur simultaneously. Thus, under the coordinated action of the linkage mechanism composed of multiple connecting arms 12 and 13, the motion is sequentially transmitted to the remaining sliders 9. The displacement of the sliders 9 drives the knife holder 14 and the slitting blades 15 installed inside the knife holder 14 to move synchronously, thereby achieving the effect of quickly adjusting the spacing of the slitting blades 15 to adapt to different width slitting operations.

[0038] Reference Figure 4 and Figure 5The guiding assembly includes multiple guide rollers 16, which are made of stainless steel and chrome-plated to enhance wear resistance. The guide rollers 16 are arranged in a zigzag pattern between the support plates 2. Both ends of each guide roller 16 are rotatably connected to a rotating seat 17 via deep groove ball bearings. The rotating seat 17 is made of cast iron and has a dovetail groove structure at the bottom, forming a sliding fit with the grooves 3 on the sidewall of the support plate 2. This supports the guide rollers 16 and allows for longitudinal displacement. Multiple grooves 3 are formed on the sidewall of the support plate 2 by milling. The positions of the grooves 3 correspond to the positions of the guide rollers 16. The rotating seats 17 are slidably connected inside the grooves 3. Each rotating seat 17 has a buffer spring 21 at its bottom. Made of spring steel, one end of each buffer spring 21 is fixedly connected to the inner wall of the slide groove 3, and the other end of each buffer spring 21 is fixedly connected to the bottom of the rotating seat 17. A connecting seat 20 is fixedly connected to one side wall of the rotating seat 17 to reduce the vibration when the rotating seat 17 slides. An electric actuator 18 is provided at the bottom of each connecting seat 20. The electric actuator 18 is used to provide power for the displacement of the rotating seat 17. The electric actuator 18 is existing technology and will not be described in detail here. The outer wall of each electric actuator 18 is fixedly connected to the side wall of the support plate 2 through a ring bracket. A push rod 19 is fixedly connected to the output end of each electric actuator 18. The push rod 19 is made of alloy structural steel and is used to transmit precise linear driving force. The top of each push rod 19 is fixedly connected to the bottom of the connecting seat 20.

[0039] Specifically, when the metal strip shifts laterally or wrinkles due to tension fluctuations during high-speed conveying, the tension sensor integrated inside the guide roller 16 detects the tension change in real time and converts the analog signal into a digital signal, which is then transmitted to the control system of the control console 22. The control system calculates the required compensation displacement using a preset control algorithm and sends an action command to the electric actuator 18 in the corresponding area. Upon receiving the command, the output end of the electric actuator 18 drives the push rod 19 to move linearly. If the metal strip shifts to the left, the push rod 19 of the left electric actuator 18 extends forward, and the push rod 19 of the right electric actuator 18 retracts backward; and vice versa. The displacement of the push rod 19 is transmitted to the connecting seat 20 through a pin, and the connecting seat 20 drives the rotating seat 17 to slide laterally along the slide groove 3 of the support plate 2. The sliding direction of the rotating seat 17 in the chute 3 is opposite to the offset direction of the metal strip: when the metal strip offsets to the left, the rotating seat 17 of the left guide roller 16 slides to the left, and the rotating seat 17 of the right guide roller 16 slides to the right, forming a symmetrical tension compensation angle. During the sliding process, the buffer spring 21 at the bottom of the rotating seat 17 undergoes elastic deformation due to compression or stretching. The spring force helps adjust the displacement speed of the guide roller 16 to avoid rigid impact. After the guide roller 16 is displaced with the rotating seat 17, the angle between its axis and the running direction of the metal strip changes. Through the angle adjustment of the zigzag path, a reverse lateral force is applied to the metal strip to counteract the offset trend caused by tension fluctuation. When the sensor detects that the tension has recovered to the set threshold, the PLC system sends a command to stop the electric pusher 18. The guide roller 16 maintains its current position, completing the dynamic compensation of tension fluctuation, ensuring stable conveying of the metal strip, and avoiding the impact of offset or wrinkles on the slitting accuracy.

[0040] Working principle: When using this ultra-thin metal strip slitting unit, one end of the metal strip is first passed between the guide rollers 16 to form a zigzag guide path, which increases the frictional coupling between the metal strip and the roller surface of the guide rollers 16. Then, it is cut into strips by the slitting knife 15. The slitting metal strip is then fixed on the outer wall of the carrying roller 7. The output end of the drive motor 4 drives the power roller 6 to rotate. Subsequently, the power roller 6 winds the metal strip and pulls the unslitting metal strip to move.

[0041] When the metal strip is easily shifted laterally or wrinkled due to tension fluctuations during high-speed conveying, the sensor inside the guide roller 16 transmits the data to the control console 22. The control console 22 controls the corresponding electric pusher 18 to start working. The electric pusher 18 drives the push rod 19 to move, which in turn drives the connecting seat 20 to move. The displacement of the connecting seat 20 causes the rotating seat 17 to slide in the slide groove 3, which in turn causes the guide roller 16 to move as well. Thus, the guide roller 16 can automatically compensate for the offset according to the tension of the metal strip.

[0042] When it is necessary to adjust the spacing of the slitting blades 15 to adapt to slitting operations of different widths, the operator controls the hydraulic rod 11 through the control console 22. The output end of the hydraulic rod 11 pushes the fixed block 10 to move. The displacement of the fixed block 10 then drives the slider 9 on one side to slide on the outer wall of the guide plate 8. The displacement of the slider 9 causes the connecting arm 12 and connecting arm 23 at its top to rotate. The rotation of connecting arm 12 and connecting arm 23 drives the connecting arm 12 and connecting arm 23 at the top of another slider 9 connected to it to also rotate. Then, under the coordinated action of multiple connecting arms 12 and connecting arm 23, the motion is transmitted to the remaining multiple sliders 9 in sequence to move inward or outward, thereby driving the blade holder 14 and the slitting blades 15 to move, thus achieving the effect of quickly adjusting the spacing of the slitting blades 15.
