Description

Technical Field

[0001] This utility model relates to the technical field of dynamic balancing calibration machines for paper roll conveyor shafts, and in particular to a dynamic balancing calibration machine for paper roll conveyor shafts. Background Technology

[0002] On a paper production line, the roll conveyor shaft needs to rotate at high speed and stably to ensure the flatness and continuous transport of the paper. Due to uneven material, processing errors, assembly errors, and other reasons, unbalanced forces can be generated. Therefore, the roll conveyor shaft needs to be installed on a dynamic balancing machine. By measuring the vibration signals generated by the rotating shaft during rotation, the magnitude and location of the unbalance can be determined. Then, based on the measurement results, the rotating shaft can be adjusted by removing or adding weight, so that the center of gravity of the rotating shaft coincides with the center of rotation, thereby achieving dynamic balance.

[0003] The existing paper roll conveyor shaft is placed on a roller support on a dynamic balancing calibration machine and installed on the dynamic balancing calibration machine through the cooperation of a lead screw and a fixture. However, the vibration force generated by the high-speed rotation of the paper roll conveyor shaft will be transmitted to the fixture and the lead screw, which will easily cause the lead screw to rotate. This will result in the paper roll conveyor shaft being unstable on the dynamic balancing calibration machine, thus affecting the accuracy of the measurement. Utility Model Content

[0004] Therefore, it is necessary to provide a dynamic balancing calibration machine for the paper roll conveyor shaft to address the problem of instability when mounted on the dynamic balancing calibration machine.

[0005] The device includes: a calibration platform, a driving mechanism on the top of which is fixedly connected to a fixed block; a lead screw rotatably connected to the inner wall of the fixed block; and a clamping block threaded onto the surface of the lead screw. It also includes an anti-deviation mechanism, comprising a fixed frame fixedly connected to one side of the fixed block; an anti-slip rod and a rubber plate slidably connected to the inner wall of the fixed frame; a rubber rod rotatably connected to the inner wall of the rubber plate; an iron block fixedly connected to the front end of the fixed frame; the surface of the rubber rod slidably connected to the inner wall of the iron block; a driving disk fixedly connected to one end of the lead screw; and the surface of the anti-slip rod engaging with the inner wall of the driving disk.

[0006] In one embodiment, a magnetic block is slidably connected to the inner wall of the iron block, and the surface of the magnetic block is engaged with the inner wall of the rubber rod, and the surface of the magnetic block is magnetically attracted to the inner wall of the iron block.

[0007] In one embodiment, a rubber block is slidably connected to the inner wall of the iron block, and the surface of the rubber block is engaged with the inner wall of the magnetic block.

[0008] In one embodiment, a limiting ring is fixedly connected to the top of the rubber plate. The limiting ring precisely limits the rotation of the rubber rod, ensuring that the rubber rod can quickly slide out of the iron block.

[0009] In one embodiment, a coil spring is fixedly connected to the surface of the rubber rod, and the other end of the coil spring is fixedly connected to the inner surface of the limiting ring.

[0010] In one embodiment, a spring is fixedly connected to one side of the anti-slip rod, and the other end of the spring is fixedly connected to the inner wall of the fixed frame. The elastic force of the spring pushes the anti-slip rod to move automatically and lock into the drive plate, and the elastic force of the coil spring pushes the rubber rod to rotate automatically within the rubber plate and iron block, so that the end of the rubber rod abuts against the bottom of the iron block.

[0011] In one embodiment, the inner surface of the clamping block is slidably connected to the outer surface of the fixing block.

[0012] In one embodiment, the driving mechanism includes a positioning block fixedly connected to the top of the calibration platform, and the inner walls of the positioning block and the clamping block are rotatably connected to limit sleeves.

[0013] In one embodiment, a servo motor is fixedly connected to one side of the positioning block, and the output shaft of the servo motor is fixedly connected to one end of one of the limiting sleeves.

[0014] In one embodiment, a support block is fixedly connected to the top of the calibration platform. The top of the support block is recessed in a "V" shape, and two support wheels are rotatably connected to the inner wall of the support block.

[0015] Beneficial effects 1. By cooperating with the rubber plate and the rubber rod, the anti-slip rod is locked, which makes the anti-slip rod stably stuck in the drive plate, thereby locking the lead screw and ensuring stable clamping of the paper roll conveyor shaft. This prevents the paper roll conveyor shaft from shifting during rotation on the dynamic balancing calibration machine and ensures the accuracy of the measurement of the paper roll conveyor shaft. 2. By cooperating with the rubber block and the magnetic block, the rubber rod is self-locked, preventing it from rotating and detaching from the iron block. This ensures stable locking of the rubber plate, keeping the anti-slip rod securely locked in the drive disc, and thus achieving stable locking of the lead screw, thereby ensuring stable clamping of the paper roll conveyor shaft.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] The following is combined Figures 1-5 This invention describes a dynamic balancing calibration machine for a paper roll conveyor shaft.

[0021] In one embodiment, a dynamic balancing calibration machine for a paper conveyor shaft includes: a calibration platform 100, a drive mechanism 200 on the top of the calibration platform 100, a fixed block 400 fixedly connected to the top of the calibration platform 100, a lead screw 500 rotatably connected to the inner wall of the fixed block 400, and a clamping block 300 threadedly connected to the surface of the lead screw 500; it also includes an anti-deviation mechanism 600, which includes a fixed frame 607 fixedly connected to one side of the fixed block 400, an anti-slip rod 602 and a rubber plate 603 slidably connected to the inner wall of the fixed frame 607, a rubber rod 605 rotatably connected to the inner wall of the rubber plate 603, an iron block 604 fixedly connected to the front end of the fixed frame 607, a surface of the rubber rod 605 slidably connected to the inner wall of the iron block 604, a drive disk 601 fixedly connected to one end of the lead screw 500, and a surface of the anti-slip rod 602 snapped into the inner wall of the drive disk 601.

[0022] It should be noted that rubber corrugated sleeves are fixedly connected to both sides of the clamping block 300, and the other end of the rubber corrugated sleeve is fixedly connected to one side of the fixing block 400. The surface of the lead screw 500 is located inside the rubber corrugated sleeve.

[0023] In this embodiment, when the paper conveyor shaft needs to be positioned on the calibration table 100, the paper conveyor shaft is placed on the drive mechanism 200, the drive disk 601 is rotated, and the lead screw 500 rotates to drive the clamping block 300 to move laterally to a suitable position, thereby clamping the paper conveyor shaft. The anti-slip rod 602 is pushed to move laterally within the fixed frame 607 and is locked within the drive disk 601. The rubber plate 603 is pushed to move down within the fixed frame 607 and abut against the inner wall of the fixed frame 607, so that the rubber rod 605 moves down to the iron block 604. The rubber rod 605 is rotated so that the end of the rubber rod 605 abuts against the bottom of the iron block 604, thereby locking the rubber plate 603 longitudinally, so that the anti-slip rod 602 is stably locked within the drive disk 601.

[0024] like Figure 3-4 As shown, a magnetic block 606 is slidably connected to the inner wall of the iron block 604. The surface of the magnetic block 606 is engaged with the inner wall of the rubber rod 605. The surface of the magnetic block 606 is magnetically attracted to the inner wall of the iron block 604. A rubber block 608 is slidably connected to the inner wall of the iron block 604. The surface of the rubber block 608 is engaged with the inner wall of the magnetic block 606. A limit ring 609 is fixedly connected to the top of the rubber plate 603. A coil spring 610 is fixedly connected to the surface of the rubber rod 605. The other end of the coil spring 610 is fixedly connected to the inner surface of the limit ring 609. A spring 611 is fixedly connected to one side of the anti-slip rod 602. The other end of the spring 611 is fixedly connected to the inner wall of the fixed frame 607.

[0025] In this embodiment, the restriction on the anti-slip rod 602 is loosened, and the elastic force of the spring 611 pushes the anti-slip rod 602 to move laterally and lock it in the drive disk 601. The restriction on the rubber rod 605 is loosened, and the elastic force of the coil spring 610 pushes the rubber rod 605 to rotate within the rubber plate 603 and the iron block 604. The rubber rod 605 automatically rotates and abuts against the surface of the limiting ring 609, stopping its automatic rotation. This causes the end of the rubber rod 605 to abut against the bottom of the iron block 604, pushing the magnetic block 606 to move laterally within the iron block 604 and lock it in the rubber rod 605. This pushes the rubber block 608 to move downward within the iron block 604 and lock it in the magnetic block 606, thereby locking the rubber rod 605 and stably locking the anti-slip rod 602 in the drive disk 601.

[0026] like Figure 2 As shown, the inner surface of the clamping block 300 is slidably connected to the outer surface of the fixing block 400. The driving mechanism 200 includes a positioning block 201 fixedly connected to the top of the calibration platform 100. The positioning block 201 and the inner wall of the clamping block 300 are rotatably connected to the limiting sleeve 202. A servo motor 203 is fixedly connected to one side of the positioning block 201. The output shaft of the servo motor 203 is fixedly connected to one end of one of the limiting sleeves 202. A bearing block 204 is fixedly connected to the top of the calibration platform 100. The top of the bearing block 204 is recessed in a "V" shape. Two bearing wheels 205 are rotatably connected to the inner wall of the bearing block 204.

[0027] It should be noted that a dynamic balancing calibration machine typically consists of a calibration platform 100, a positioning block 201, a limit sleeve 202, a servo motor 203, a bearing block 204, a bearing wheel 205, a clamping block 300, and a lead screw 500. The R5200 series of dynamic balancing calibration machines can be selected, as these are relatively mature devices with existing technology. The specific model can be selected according to actual needs.

[0028] In this embodiment, the paper roll drive shaft is placed on the bearing wheel 205 and one end of the paper roll drive shaft is locked in the limiting sleeve 202 on the positioning block 201. The screw 500 drives the clamping block 300 and the corresponding limiting sleeve 202 to move laterally, so that the corresponding limiting sleeve 202 is locked in the other end of the paper roll drive shaft. At this time, the PLC controller on the calibration table 100 is controlled to adjust the speed of the servo motor 203 and make the output shaft of the servo motor 203 rotate, driving the limiting sleeve 202 on the positioning block 201 to rotate, thereby making the paper roll drive shaft start to rotate. The selection of the speed is usually determined according to the working speed of the paper roll drive shaft and the requirements of the calibration machine. Generally, it should be close to the actual working speed of the shaft to more accurately simulate the working state of the shaft.

[0029] The measurement system on the dynamic balancing calibration machine collects vibration signals generated by the paper conveyor shaft during rotation using accelerometers and displacement sensors. Accelerometers measure the shaft's vibration acceleration, and displacement sensors measure its vibration displacement. The accelerometers and displacement sensors convert the collected vibration signals into electrical signals and transmit them to the signal processing device.

[0030] The signal processing unit analyzes and processes the electrical signals collected by the sensors, and calculates the magnitude and location of the imbalance on the paper roll conveyor shaft using a specific algorithm. The calculated imbalance result is displayed on the PLC controller, and the result can also be recorded for subsequent analysis and processing. Operators can use the displayed results to determine whether the shaft imbalance meets the requirements.

[0031] If the measurement results show that the imbalance of the paper roll conveyor shaft exceeds the allowable range, a correction operation is required. Correction methods typically include the weight removal method and the weight addition method. The weight removal method involves removing a portion of the material from the shaft through drilling, grinding, or other means to reduce the imbalance; the weight addition method involves adding counterweights to the shaft to increase the weight at the corresponding locations, thus achieving balance. After correction, measurements must be taken again until the shaft imbalance meets the requirements.

[0032] Working principle: Rotating the drive disk 601 causes the lead screw 500 to rotate, which in turn moves the clamping block 300 laterally to a suitable position, thereby clamping the paper conveyor shaft and loosening the restriction on the anti-slip rod 602. The elastic force of the spring 611 pushes the anti-slip rod 602 to move laterally and lock it inside the drive disk 601, pushing the rubber plate 603 down within the fixed frame 607 and abutting against the inner wall of the fixed frame 607. This causes the rubber rod 605 to move down to the iron block 604, loosening the restriction on the rubber rod 605. The coil spring 610... The elastic force pushes the rubber rod 605 to rotate within the rubber plate 603 and the iron block 604. The rubber rod 605 automatically rotates and abuts against the surface of the limiting ring 609, so that the end of the rubber rod 605 abuts against the bottom of the iron block 604. This pushes the magnetic block 606 to move laterally within the iron block 604 and lock it inside the rubber rod 605. It also pushes the rubber block 608 to move downward within the iron block 604 and lock it inside the magnetic block 606, thereby locking the rubber rod 605 and making the anti-slip rod 602 stably locked within the drive disc 601.

[0033] It should be noted that the calibration platform 100, positioning block 201, limit sleeve 202, servo motor 203, bearing block 204, bearing wheel 205, clamping block 300, lead screw 500, coil spring 610, and spring 611 mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the servo motor 203 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
