Description

Technical Field

[0001] This utility model belongs to the field of leveling machine technology, and in particular relates to a leveling device. Background Technology

[0002] In the processing and production of materials such as metal sheets, films, and paper, leveling devices are indispensable key equipment. Their core function is to eliminate defects such as bending, wrinkles, and wavy edges caused by rolling, storage, or transportation, ensuring the flatness of the material surface and providing qualified blanks for subsequent cutting, stamping, printing, and other processes.

[0003] Existing leveling devices generally suffer from asynchronous feeding and leveling actions. Most devices use independent drives for the feeding rollers and leveling rollers, or are connected by simple gear transmissions. This easily leads to transmission gaps or speed differences, causing material to stretch or accumulate during transport. This not only affects leveling accuracy but may also cause scratches on the material surface. Regarding the adjustment of the leveling roller gap, traditional adjustment mechanisms are mostly manual screw adjustments. These are prone to jamming or misalignment during adjustment, making it difficult to accurately adapt to materials of different thicknesses. Furthermore, the adjustment efficiency is low, making it unsuitable for the frequent material changes required in mass production.

[0004] To address this problem, we provide a leveling device. Utility Model Content

One end of the leveling roller 41 extends through the outside of the worktable 1 and the mounting frame 32 and is fixedly connected to a drive synchronizing sprocket 33. A driven synchronous sprocket 42 is fixedly connected, and a synchronous chain belt is sleeved between the driven synchronous sprocket 42 and the driving synchronous sprocket 33. A gap adjusting component 43 is fixedly connected to the surface of the mounting frame 32, and a first motor 44 is fixedly connected to the surface of the gap adjusting component 43. The feeding direction adjusting assembly 5 includes a screw tube 51 fixedly connected to the front and rear ends of the inner cavity of the worktable 1 through bearings. A worm gear 52 is fixedly connected to the bottom of the surface of the screw tube 51, and a worm 53 is meshed on the surface of the worm gear 52. A second motor 54 is fixedly connected between the front and rear worms 53. A lead screw 55 is threadedly connected to the inner cavity of the screw tube 51, and a mounting plate 56 is fixedly connected to the top of the lead screw 55. A direction adjusting roller 57 is fixedly connected between the front and rear mounting plates 56 through bearings.

[0027] Specifically: the components are arranged in sequence along the material conveying direction, with the auxiliary roller 2 located near the feed end of the worktable 1, the feeding direction adjustment component 5 located near the discharge end of the worktable 1, the axes of the upper and lower feeding rollers 31 being kept parallel, the outer diameters of the driven synchronous sprocket 42 and the active synchronous sprocket 33 being the same, and an annular synchronous chain belt being fitted between them to achieve synchronous power transmission, the second motor 54 driving the front and rear worm gears 53 to rotate synchronously, and the front and rear mounting plates 56 being arranged symmetrically.

[0028] The four corners of the bottom of the workbench 1 are fixedly connected to support legs. The surface of the support legs is provided with anti-slip texture, which can improve the overall stability of the device.

[0029] The gap adjustment component 43 includes a hydraulic telescopic rod 431 fixedly connected to one side of the bottom of the mounting frame 32. The bottom of the hydraulic telescopic rod 431 is fixedly connected to the worktable 1. Slide rods 432 are slidably connected to both sides of the inner cavity of the mounting frame 32 and the hydraulic telescopic rod 431. The bottom of the slide rods 432 is fixedly connected to the worktable 1. The hydraulic telescopic rod 431 provides stable adjustment power, and the slide rods 432 play a guiding and limiting role, which can prevent the mounting frame 32 from tilting or shifting during the lifting process, thereby improving the accuracy and stability of the gap adjustment.

[0030] The gap adjusting component 43 also includes a first gear 433 fixedly connected to the end of the output shaft of the first motor 44. The top of the first gear 433 is meshed with a second gear 434, a third gear 435 is meshed with one side of the first gear 433, and a fourth gear 436 is meshed with one side of the second gear 434.

The first gear 433, the second gear 434 and the fourth gear 436 are movably connected by a connecting rod. By driving the gear set through the first motor 44, the upper and lower feeding rollers 31 can be synchronously rotated in opposite directions to ensure uniform feeding force.

[0031] The bottom of the first motor 44 and the top of the second motor 54 are fixedly connected to the worktable 1 by bolts. This design improves the stability of the installation of the first motor 44 and the second motor 54.

[0032] The inner cavity of the worktable 1 and the front and rear ends of the side near the leveling roller 41 are provided with mounting holes for the installation of the solenoid 51. The mounting holes provide a precise installation positioning reference for the solenoid 51.

[0034] The surfaces of the feeding roller 31 and the direction adjusting roller 57 are both treated with sandblasting and electroplating hard chrome, while the surfaces of the leveling roller 41 and the auxiliary roller 2 are treated with thickened electroplating hard chrome. Different surface treatment processes are adopted for different rollers. Sandblasting and electroplating hard chrome on the feeding roller 31 and the direction adjusting roller 57 can improve surface roughness and wear resistance, while thickened electroplating hard chrome on the leveling roller 41 and the auxiliary roller 2 can enhance compressive strength and wear resistance, extend the service life of each roller, and ensure the stability of the leveling effect.

[0035] The working principle of this utility model is as follows: The material is first initially guided by the auxiliary roller 2 at the feeding end of the workbench 1, and then enters between the upper and lower feeding rollers 31 of the feeding assembly 3. After the first motor 44 starts, it drives the active synchronous sprockets 33 of the top and bottom feeding rollers 31 to rotate through the gear set. The active synchronous sprockets 33 drive the driven synchronous sprockets 42 and the leveling rollers 41 of the leveling assembly 4 to rotate synchronously through the synchronous chain belt, so as to realize the synchronous operation of feeding and leveling. The gap adjustment component 43 can adjust the upper and lower feeding rollers 31 and the leveling rollers 41 by lifting the mounting frame 32 through the hydraulic telescopic rod 431 according to the thickness of the material. The gap between the flat rollers 41 and the slide bar 432 ensure that the lifting and lowering process of the mounting frame 32 is stable and does not deviate. After the material is leveled by the leveling rollers 41, it enters the area of ​​the feeding direction adjustment component 5. The second motor 54 starts to drive the front and rear worm gears 53 to rotate. The worm gears 53 drive the meshing worm wheel 52 and the screw tube 51 to rotate. The screw tube 51 and the lead screw 55 are threaded together to realize the lifting and lowering of the lead screw 55. Then, the mounting plate 56 drives the direction adjustment roller 57 to move up and down to adjust the material conveying angle and realize the precise correction of the feeding direction. Finally, the leveled and oriented material is output from the discharge end to provide qualified blanks for subsequent processes.
