Description
Technical Field
[0001] This utility model relates to the field of circular blade scraper waste removal technology, and in particular to a digital display device for circular blade scrapers. Background Technology
[0002] The main function of the scraper on the circular blade is waste removal and peeling. Currently, the scraper is adjusted by technicians based on experience. It usually requires repeated fine-tuning of the angle between the scraper and the circular blade to find the working condition that achieves the best waste removal effect. Because everyone's familiarity with and understanding of the process is different, each adjustment of the scraper angle requires multiple attempts, which affects adjustment and production efficiency. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies where, due to varying levels of familiarity and understanding of the process, multiple attempts are required each time the scraper angle is adjusted, affecting adjustment and production efficiency. Therefore, a digital display device for circular scrapers is proposed.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a digital display device for a circular scraper, comprising a support rod, with rotating arms fixed on both sides of the support rod, a scraper body mounted on one side of the support rod, a first rotating plate at one end of the scraper body, and a second rotating plate at the other end of the scraper body, four movable slots on the top surface of the second rotating plate, each movable slot having a return spring installed inside, and a nut on the top of each of the four movable slots, a mounting plate on the top of the second rotating plate, guide rods at each corner of the bottom surface of the mounting plate, blocking blocks on the bottom surface of each of the four guide rods, a limiting and receiving groove on the top surface of the mounting plate, a digital display level mounted on the top of the mounting plate, a base plate at the bottom of the digital display level, and a strong magnet at the bottom of the base plate.
[0005] Preferably, both ends of the support rod are bolted to the two rotating arms, and the support rod passes through one end of the first rotating plate and the second rotating plate.
[0006] Preferably, the top surface of the scraper body is bolted to the bottom surface of the first rotating plate and the second rotating plate at the end away from the support rod.
[0007] Preferably, the nuts on the top of the second rotating plate are all threadedly connected to the second rotating plate, and the four reset springs are all fixed in the movable grooves on the top surface of the second rotating plate by nuts.
[0008] Preferably, the guide rods at each corner of the bottom surface of the mounting plate are integrally formed with the mounting plate, and the bottom ends of the guide rods are all inserted through nuts and installed into movable grooves.
[0009] Preferably, the four blocking blocks on the bottom surface of the guide rod are welded to the guide rod, and the blocking blocks are all installed in the movable groove. The bottom surface of the blocking block is in contact with the top surface of the return spring, and the top surface of the blocking block is in contact with the nut.
[0010] Preferably, the base plate of the digital display level is installed on the bottom surface of the digital display level and is bolted to the digital display level. The strong magnet at the bottom of the base plate is fitted into the base plate and is bolted to the base plate. The strong magnet is installed into the limiting storage groove on the bottom surface of the mounting plate.
[0011] Beneficial effects In this invention, when a digital display level is mounted on a mounting plate, the base plate of the level is entirely attached to the top surface of the mounting plate. A strong magnet for attracting metal surfaces is mounted on the bottom surface of the base plate, with the bottom end of the magnet partially protruding from the base plate. A pre-drilled limiting and receiving groove matching the shape of the magnet is provided on the top surface of the mounting plate, allowing the protruding end of the strong magnet to be precisely embedded within this groove during installation. Because the mounting plate is made entirely of metal, a reliable magnetic attraction is generated between the protruding part of the magnet and the mounting plate. Combined with the positioning and limiting of the magnet around its perimeter by the limiting and receiving groove, the assembly of the digital display level on the mounting plate is both stable and less prone to displacement. The digital display level is calibrated for absolute level at the factory. When adjusting the scraper angle, the adjustment mechanism simultaneously drives the first and second rotating plates to rotate synchronously, causing a change in the tilt angle of the two rotating plates relative to the horizontal reference. The digital display level, fixed to the mounting plate on the second rotating plate, reads and displays the angle change value of the rotating plate in real time, thus forming an angle reference that can be directly observed and repeatedly aligned. Once the scraper achieves optimal waste removal during the initial machine setup, simply record the corresponding digital display angle. Subsequent setups can then quickly rotate to the same angle based on the recorded data, eliminating the need for multiple trial cuts and repeated fine-tuning to restore the optimal scraper state. This significantly reduces setup time and improves production efficiency. It also solves the problem of requiring multiple attempts to adjust the scraper angle each time, which negatively impacts setup and production efficiency due to varying levels of familiarity and understanding of the process.

Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.
[0015] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1: Reference Figure 1-6A digital display device for a circular scraper includes a support rod 1, with rotating arms 2 fixed to both sides of the support rod 1. A scraper body 3 is mounted on one side of the support rod 1. A first rotating plate 4 is provided at one end of the scraper body 3, and a second rotating plate 5 is provided at the other end of the scraper body 3. The top surface of the second rotating plate 5 has four movable slots 6, each with a return spring 7 installed inside. Nuts 8 are provided on the top of each of the four movable slots 6. A mounting plate 11 is provided on the top of the second rotating plate 5. Guide rods 10 are provided at each corner of the bottom surface of the mounting plate 11, and blocking blocks 9 are provided on the bottom surface of each of the four guide rods 10. A limiting storage slot 12 is provided on the top surface of the mounting plate 11. A digital display level 13 is mounted on the top of the mounting plate 11. A base plate 14 is provided at the bottom of the digital display level 13, and a strong magnet 15 is provided at the bottom of the base plate 14. Both ends of the support rod 1 are bolted to the two rotating arms 2, and the support rod 1 passes through one end of the first rotating plate 4 and the second rotating plate 5. The top surface of the scraper body 3 is connected to the first rotating arm 2. The bottom surfaces of the rotating plate 4 and the second rotating plate 5 are bolted together at the ends away from the support rod 1. Nuts 8 on the top of the second rotating plate 5 are threaded onto the second rotating plate 5. Four return springs 7 are fixed in the movable grooves 6 on the top surface of the second rotating plate 5 via nuts 8. Guide rods 10 at each corner of the bottom surface of the mounting plate 11 are integrally formed with the mounting plate 11, and the bottom ends of the guide rods 10 pass through the nuts 8 and are installed into the movable grooves 6. The blocking blocks 9 on the bottom surfaces of the four guide rods 10 are connected to the guide rods 10. Welding is performed, and all blocking blocks 9 are installed into the movable groove 6. The bottom surface of the blocking block 9 is in contact with the top surface of the return spring 7, and the top surface of the blocking block 9 is in contact with the nut 8. The base plate 14 at the bottom of the digital display level 13 is installed on the bottom surface of the digital display level 13, and the base plate 14 is bolted to the digital display level 13. The strong magnet 15 at the bottom of the base plate 14 is embedded in the base plate 14, and the strong magnet 15 is bolted to the base plate 14. The strong magnet 15 is installed into the limiting storage groove 12 on the bottom surface of the mounting plate 11.
[0017] The support rod 1 is positioned at the center of the device, serving as the rotational axis for the first rotating plate 4 and the second rotating plate 5. Both ends of the support rod 1 are bolted to the two rotating arms 2, ensuring the rotating arms 2 are stably fixed to the equipment frame and providing the rotational fulcrum for the entire scraper. The scraper body 3 is located on one side of the support rod 1, with its top surface bolted to the bottom surfaces of the first rotating plate 4 and the second rotating plate 5, respectively, at the ends furthest from the support rod 1. This allows the scraper body 3 to rotate synchronously with the two rotating plates and change angles during adjustment. The first rotating plate 4 and the second rotating plate 5 jointly perform the rotational adjustment function of the scraper body 3. The support rod 1 passes through both plates and serves as the pivot, allowing the rotating plates to rotate around the support rod 1, thereby adjusting the angle of the scraper body 3. The top of the second rotating plate 5 has four movable slots 6, each containing a return spring 7. The tops of the four return springs 7 are respectively attached to the bottom surface of the blocking block 9. The blocking block 9 is welded to the bottom surface of the guide rod 10. The guide rod 10 is integrally formed with the mounting plate 11. The guide rod 10 passes through the nut 8 and is inserted into the movable slot 6, allowing the mounting plate 11 to be limited and guided along the direction of the guide rod 10. When the mounting plate 11 undergoes slight displacement due to adjustment or vibration, the return spring 7 in the movable slot 6 pushes upward against the blocking block 9, the blocking block 9 supports the guide rod 10, and the guide rod 10 drives the mounting plate 11 back to its original position. This ensures that the mounting plate 11 remains stably attached to the top of the second rotating plate 5, without any tilting or loosening, and protects the digital display level 13 from damage caused by the strong vibration of the circular knife machine. Nut 8 is fixed to the second rotating plate 5 by threads, ensuring that the compression of the return spring 7 in the movable groove 6 remains consistent. Simultaneously, nut 8 blocks the blocking block 9, restricting the vertical movement of the guide rod 10 and the blocking block 9, thus ensuring the stable and reliable vertical position of the mounting plate 11. The mounting plate 11 is fixedly installed on the top of the second rotating plate 5, and its top surface has a limiting storage groove 12. The depth and contour of the storage groove match the shape of the strong magnet 15 below the base plate 14 of the digital level 13. When the digital level 13 is installed, its base plate 14 is in contact with the top surface of the mounting plate 11. The strong magnet 15 embedded below the base plate 14 protrudes from the base plate 14 and is embedded in the limiting storage groove 12, causing the magnet to attract the mounting plate 11. Because the mounting plate 11 is made of metal, a stable magnetic attraction is formed between the strong magnet 15 and the mounting plate 11, allowing the digital level 13 to be firmly attached to the mounting plate 11. Simultaneously, the limiting and receiving groove 12 limits the circumferential position of the strong magnet 15, preventing the digital level 13 from slipping or rotating horizontally, ensuring that the measuring direction of the level is consistent with the rotation direction of the rotating plate. The digital level 13 is mounted on the top surface of the base plate 14 and is fixed to the base plate 14 with bolts, enabling it to accurately read the angle of the mounting plate 11.The digital level 13 is factory-calibrated for absolute leveling. Therefore, when the first rotating plate 4 and the second rotating plate 5 rotate around the support rod 1, the mounting plate 11 rotates with the second rotating plate 5, causing the digital level 13 to rotate at the same angle. The digital level 13 can then display the angle change value in real time. The base plate 14 and the strong magnet 15 are integrally mounted on the bottom surface of the digital level 13. The strong magnet 15 is embedded in the limiting and receiving groove 12. Through magnetic attraction and the limiting effect within the groove, the posture of the digital level 13 is kept stable, making the angle display accurate and reliable. Specific Implementation Example 2: Reference Figure 1-6 A digital display device for a circular scraper, further based on the basic structure in Specific Embodiment 1, includes a highly sensitive tilt sensing unit internally configured in the digital display level 13. This unit is typically composed of a liquid capacitive sensing module or a MEMS micromechanical accelerometer. Its internal sensing core continuously detects changes in the component of gravity along the sensor coordinate axis. When the digital display level 13 is fixed on the mounting plate 11, the orientation of the mounting plate 11 tilts as the second rotating plate 5 rotates around the support rod 1, causing a change in the tilt angle of the sensing chip inside the digital display level 13 relative to the direction of gravity. This tilt angle change is acquired in real time by the tilt sensing unit and converted into a corresponding analog electrical signal. The internal circuitry filters, amplifies, and digitizes this analog signal. The built-in A / D conversion module converts the analog voltage content into digital data, and then the processing chip of the digital display level 13 converts the tilt angle into an angle value according to a preset algorithm and calibration data. The processing chip continuously calculates the proportions of the gravity component along the X and Y axes of the level's own coordinate system, obtains the current tilt angle through inverse trigonometric functions, and then outputs the calculated angle as a numerical value on the display screen. The digital level 13 has undergone absolute leveling by a reference instrument at the factory and internally stores the initial zero point and error compensation curve, ensuring reliable angle readings without manual calibration during subsequent use. When the mounting plate 11 rotates around the support rod 1 following the second rotating plate 5, the mounting plate 11 maintains a rigid connection with the level and remains stable under the dual fixation of the strong magnet 15 and the limiting storage slot 12, ensuring that the tilt angle change of the level's internal sensor completely corresponds to the actual tilt angle of the rotating plate. When the rotating plate rotates slightly, the internal sensor immediately senses the slight change in the direction of gravity, and the processing chip updates the angle value in real time using a high sampling rate algorithm, ensuring that the angle change caused by each scraper angle adjustment is accurately displayed on the screen. Since the angle value read by the digital display level 13 directly corresponds to the actual angle of the scraper body 3, the operator can record this angle after adjusting the scraper to the best waste removal effect for the first time. When adjusting the machine again, the operator only needs to rotate the scraper mechanism to the same angle to restore the same process state. This eliminates the need to rely on experience or repeated trial cuts, effectively avoids angle errors, and improves the efficiency of machine adjustment.
[0019] In summary: 1. When the digital display level 13 is mounted on the mounting plate 11, the base plate 14 of the digital display level 13 is completely attached to the top surface of the mounting plate 11. A strong magnet 15 for attracting metal surfaces is installed on the bottom surface of the base plate 14, and the bottom end of the strong magnet 15 protrudes from the base plate 14. The top surface of the mounting plate 11 is pre-cut with a limiting and receiving groove 12 that matches the shape of the magnet. The protruding end of the strong magnet 15 is precisely embedded in the limiting and receiving groove 12 during installation. Since the mounting plate 11 is made entirely of metal, a reliable magnetic attraction force is generated between the protruding part of the magnet and the mounting plate 11. Combined with the positioning and limiting of the magnet around the perimeter by the limiting and receiving groove 12, the assembly of the digital display level 13 on the mounting plate 11 is both stable and not prone to displacement. The digital display level 13 is factory-calibrated for absolute level. When adjusting the scraper angle, the adjustment mechanism simultaneously drives the first rotating plate 4 and the second rotating plate 5 to rotate synchronously, causing the tilt angle of the two rotating plates relative to the horizontal reference to change. The digital display level 13, fastened to the mounting plate 11 of the second rotating plate 5, reads and displays the angle change value of the rotating plate in real time, thus forming an angle reference that can be directly observed and repeatedly aligned. After the scraper achieves the best waste removal effect during the initial machine adjustment, only the corresponding digital display angle needs to be recorded. Subsequent machine adjustments can quickly rotate to the same angle according to the recorded data, eliminating the need for multiple trial cuts and repeated fine adjustments to restore the optimal scraper state, significantly reducing adjustment time and improving production efficiency. This solves the problem that due to varying levels of familiarity and understanding of the process, multiple attempts are required each time the scraper angle is adjusted, affecting adjustment and production efficiency.
