Description

Technical Field

[0001] The utility model relates to the technical field of rewinding machines, in particular to a slitting rewinding machine with an automatic deviation correction function. Background Art

[0002] A slitting rewinding machine is a mechanical device used to slit wide materials such as paper, film, aluminum foil, non-woven fabric, etc. into narrower strips and rewind these strips into compact rolls. Such machines are very common in packaging, printing, textile and other related industries for producing final products or preparing materials for subsequent processing steps.

[0003] Currently, the existing slitting rewinding machines cannot achieve multi-dimensional flexible adjustment and precise positioning of the ultrasonic deviation corrector under various working conditions, resulting in a reduction in deviation correction accuracy and efficiency, and affecting the linearity and quality stability of material transportation. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defect in the prior art that the ultrasonic deviation corrector cannot achieve multi-dimensional flexible adjustment and precise positioning under various working conditions, resulting in a reduction in deviation correction accuracy and efficiency, and to propose a slitting rewinding machine with an automatic deviation correction function.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A slitting rewinding machine with an automatic deviation correction function, comprising:

[0007] A frame and an ultrasonic deviation corrector. One side of the frame is fixedly provided with a support frame. A pay-off roll is rotatably arranged on the side of the support frame close to each other. On the other side of the frame, two groups of card slots are longitudinally symmetrically arranged. The inside of the two groups of card slots can be detachably provided with take-up rolls. Four universal brake wheels are fixedly arranged at the bottom of the frame in a rectangular shape;

[0008] A tension adjustment assembly, which is arranged on the frame and is used to adjust the tension of the conveyed material;

[0009] A driving mechanism, which is arranged on the frame and is used to drive the take-up roll to rotate;

[0010] A position adjustment assembly, which is arranged on the frame and is used to adjust the position of the ultrasonic deviation corrector.

[0011] In a possible design, the tension adjustment assembly includes two same movable frames rotatably arranged on both sides of the inner wall of the frame. The same pressure roll is rotatably arranged on the side of the movable frames close to each other. The same cross bar is fixedly arranged on both sides of the inner wall of the frame, and an electric push rod is hinged on one side of the cross bar. The output end of the electric push rod is hinged to one side of the movable frame.

[0012] In a possible design, the driving mechanism includes two rotating shafts longitudinally arranged on one side of the frame below the two card slots. Active gears are fixedly arranged on the outer parts of the two rotating shafts. Synchronous wheels are fixedly arranged on the outer parts of the two rotating shafts outside the active gears. The outer parts of the two synchronous wheels are sleeved with the same first synchronous belt. A driven pulley is fixedly arranged on the outer part of one of the rotating shafts below between the synchronous wheel and the active gear. An installation frame is fixedly arranged on one side of the frame. A second motor is fixedly arranged on the top of the installation frame. A driving pulley is fixedly arranged on the outer part of the output shaft of the second motor. The outer parts of the driving pulley and the driven pulley are sleeved with the same second synchronous belt. Driven gears are fixedly arranged on the outer parts of one ends of the two winding rollers. The driven gears and the active gears can be disengaged from meshing with each other.

[0013] In a possible design, the position adjustment assembly includes two frames symmetrically and fixedly arranged on both sides of the frame. Fixed frames are fixedly arranged on the outer sides of the two frames. Sliders are slidably arranged on both sides of the inner walls of the two fixed frames. Threaded rods penetrate and are connected to one sides of the two fixed frames. The inner ends of the threaded rods are rotatably connected to the sliders. Adjusting blocks are fixedly arranged at the outer ends of the threaded rods. Threaded rods penetrate and are connected to one sides of the two sliders. Handwheels are fixedly arranged at the outer ends of the two threaded rods. Sleeve tubes are sleeved on the inner ends of the two threaded rods. Adjusting bolts penetrate and are connected to one sides of the two sleeve tubes. The two ultrasonic deviation rectifiers are respectively fixedly arranged at one ends of the two sleeve tubes.

[0014] In a possible design, two limiting rollers are symmetrically and rotatably arranged on both sides of the inner wall of the frame beside the unwinding roller. Two guiding rollers are symmetrically and rotatably arranged on both sides of the inner wall of the frame beside the ultrasonic deviation rectifier.

[0015] In a possible design, two rotating rollers are symmetrically and rotatably arranged in the middle of the two guiding rollers on both sides of the inner wall of the frame. A plurality of circular knives are slidably arranged on the outer part of the upper rotating roller. A plurality of knife seats equal in number to the circular knives are slidably arranged on the outer part of the lower rotating roller. Locking bolts are arranged on the plurality of knife seats and the plurality of circular knives. A first motor is fixedly arranged on one side of the frame. One end of the output shaft of the first motor is fixedly connected to the upper rotating roller.

[0016] In this application, when starting to use, first, the parts with bearings at both ends of the two winding rollers are respectively clamped into the card slots on both sides of the frame, and it is ensured that the driven gears on the two winding rollers are engaged with the driving gear. Subsequently, the material to be slit and rewound is placed on the unwinding roller, and it is ensured that the material enters the equipment stably through the limiting roller. Subsequently, according to needs, an appropriate number of circular knives and corresponding tool holders are adjusted on the rotating roller, and the circular knives and tool holders are slid on the rotating roller to a suitable position. Subsequently, the positions of the circular knives and tool holders are locked using locking bolts;

[0017] Then start the electric push rod. The output end of the electric push rod expands and contracts to push the movable frame to move, thereby adjusting the pressure of the pressure roller on the material and realizing the tension adjustment during the material conveying process. Then rotate the adjustment block. While the adjustment block rotates, it drives the threaded rod to rotate. While the threaded rod rotates, it pushes the slider to slide inside the fixed frame, thereby driving the ultrasonic deviation rectifier to move horizontally towards the material. Subsequently, rotate the hand wheel. While the hand wheel rotates, it drives the lead screw to rotate. While the lead screw rotates, it pushes the ultrasonic deviation rectifier to move towards the material and approach the material. Subsequently, rotate the ultrasonic deviation rectifier until the material is located between the ultrasonic deviation rectifiers. After the position of the ultrasonic deviation rectifier is adjusted, the position of the ultrasonic deviation rectifier is locked through the adjustment bolt, so that the edge position of the material is located at the best monitoring positions of the two ultrasonic deviation rectifiers;

[0018] Then start the second motor. The output shaft of the second motor drives the driving pulley to rotate. While the driving pulley rotates, it drives the driven pulley and the lower rotating shaft to rotate through the second synchronous belt. While the rotating shaft rotates, the synchronous pulley on it drives another synchronous pulley to rotate through the first synchronous belt and transmits the power to its rotating shaft, so that the two rotating shafts rotate synchronously. While the two rotating shafts rotate synchronously, the driving gears on the rotating shafts rotate synchronously. Since the driving gears are engaged with the driven gears at one end of the winding rollers, when the two driving gears rotate, they respectively drive the two winding rollers to rotate, and the rewinding process of the material starts;

[0019] Then drive the upper rotating roller to rotate through the first motor. While the rotating roller rotates, it drives the circular knives on it to rotate synchronously. When the material enters the slitting area through the guiding roller, the slitting and cutting are completed by the cooperation of the circular knives and the tool holders. The slit material continues to be conveyed forward and is then sent into the winding area, where it is rewound by the two winding rollers respectively;

[0020] When the material deviates, the ultrasonic deviation rectifier emits a signal, and through the control system, the guiding roller or other relevant components are adjusted to make the material return to the predetermined position, realizing automatic deviation rectification. When the material rewinding is completed, stop the second motor, turn off all power sources, take out the rewound material roll, replace the new winding rollers and / or adjust the circular knife configuration, and prepare for the next round of work.

[0021] The utility model has the following beneficial effects:

[0022] In the present utility model, through the setting of the tension adjustment component, by utilizing the telescopic function of the electric push rod, the movable frame is flexibly pushed to move, thereby accurately adjusting the pressure of the pressure roller on the material, realizing the dynamic adjustment and stable control of the tension during the material conveying process, effectively solving the problems of inaccurate and fluctuating tension adjustment in traditional equipment, improving the smoothness of material conveying and processing accuracy, laying a solid foundation for the subsequent processing process, and significantly enhancing the production efficiency and product quality;

[0023] In the present utility model, through the setting of the drive mechanism, after starting the second motor, its power is transmitted to the rotating shaft through the driving belt pulley, the second synchronous belt and the driven belt pulley, and then the power synchronization transmission between the two rotating shafts is realized by using the first synchronous belt. In this process, the driving gear on the rotating shaft is accurately meshed with the driven gear at the end of the rewinding roller, ensuring that the two rewinding rollers can rotate synchronously and stably, thereby starting the rewinding operation of the material, and realizing the high-efficiency synchronous rotation of the two rewinding rollers, which not only simplifies the transmission structure, improves the energy transmission efficiency, but also ensures the smoothness and consistency of the rewinding process, and significantly enhances the production efficiency and product quality;

[0024] In the present utility model, through the setting of the position adjustment component, by rotating the adjustment block and the hand wheel, the rotation of the threaded rod and the screw rod are respectively driven, and then the slider and the ultrasonic deviation corrector are driven to move smoothly along the preset track until they are accurately positioned at the best monitoring position on the edge of the material. Subsequently, by directly rotating the ultrasonic deviation corrector itself, its angle and position can be finely adjusted to ensure that the material is exactly within its best monitoring range, and the ultrasonic deviation corrector is firmly locked by using the adjustment bolt to ensure its stable position during the working process, thereby realizing the multi-dimensional flexible adjustment and precise positioning of the ultrasonic deviation corrector under various working conditions, not only simplifying the installation and debugging process of the deviation corrector, but also significantly improving the deviation correction accuracy and efficiency, and effectively ensuring the straightness and quality stability of the material conveying;

[0025] In the present utility model, through the setting of the position adjustment component, the multi-dimensional flexible adjustment and precise positioning of the ultrasonic deviation corrector under various working conditions are realized, which not only simplifies the installation and debugging process of the deviation corrector, but also significantly improves the deviation correction accuracy and efficiency, and effectively ensures the straightness and quality stability of the material conveying.

On both sides of the inner wall of the frame 1, adjacent to the unwinding roller 3, two limiting rollers 4 are symmetrically and rotatably arranged through bearings or similar devices. The main function of the limiting rollers 4 is to limit the lateral deviation of the material released from the unwinding roller 3 during the conveying process, ensuring that the material can stably enter the subsequent processing or rewinding process.

[0040] On both sides of the inner wall of the frame 1, beside the ultrasonic deviation corrector 31, two guiding rollers 9 are also symmetrically and rotatably arranged through bearings or similar devices.
