Description

Technical Field

[0001] This invention relates to the field of thinning and gap elimination technology, and in particular to a thinning roller gap elimination structure. Background Technology

[0002] In the field of material thinning processing, thinning rollers are core processing components, and their operational stability and precision directly determine the quality of product processing.

[0003] In traditional thinning roll structures, the thinning roll is mostly a single roll design, lacking an effective supporting and reinforcing structure. This makes it prone to deformation under high-speed operation or processing loads, affecting processing accuracy. At the same time, the gap between the thinning roll and the support roll is difficult to eliminate precisely, and impact vibration is easily generated during operation, which not only aggravates roll surface wear but also leads to uneven thickness of the processed material. In addition, the drive device of the traditional structure lacks an effective anti-rotation and adaptive adjustment mechanism, which can easily cause unstable power transmission during gap adjustment. Processing waste is prone to adhere and accumulate on the surface of the thinning roll and the support roll, affecting the matching accuracy of the roll system and increasing the difficulty of equipment maintenance. Moreover, existing gap elimination devices mostly use a single drive structure, which makes it difficult to simultaneously eliminate gap and correct the posture of the support components, further limiting the improvement of processing accuracy. In addition, the traditional roll gap adjustment operation is complex and requires high operator skills, which is not conducive to improving production efficiency. Summary of the Invention

[0010] A further improvement to the above technical solution is that a second scraper is disposed on one side of the upper support roller, the blade of the second scraper being adapted to and arranged in a close fit with the roller surface of the upper support roller; a second adjusting cylinder is connected to each end of the second scraper, the second adjusting cylinder being used to drive the second scraper to move along the direction closer to or farther from the roller surface of the upper support roller, so as to adjust the fit gap between the scraper and the roller surface; a second waste collection box is disposed directly below the second scraper, and a second grip handle is provided on one side of the second waste collection box.

[0011] A further improvement to the above technical solution is that a third scraper is disposed on one side of the lower support roller, the blade of the third scraper being adapted to and arranged in a close fit with the roller surface of the lower support roller; a third adjusting cylinder is connected to each end of the third scraper, the third adjusting cylinder being used to drive the third scraper to move along the direction of approaching or moving away from the roller surface of the lower support roller, so as to adjust the fit gap between the scraper and the roller surface; a second waste guide plate is provided on the side of the third scraper away from the lower support roller, the second waste guide plate being adapted to and guiding the first waste collection box, and being used to guide the waste scraped off by the third scraper into the first waste collection box.

[0021] like Figures 1 to 6As shown in the figure, this is an embodiment of the present invention, which relates to a thinning roller gap elimination structure, including a structural body 10. The structural body 10 includes a thinning composite roller 20, an upper support roller 30, a lower support roller 40, a support bearing seat 11, and a gap elimination device 50. The thinning composite roller 20 is correspondingly disposed on the same side of the upper support roller 30 and the lower support roller 40. The upper support roller 30 and the lower support roller 40 are arranged symmetrically in the vertical direction and respectively abut against the thinning composite roller 20 to enhance the rigidity of the thinning composite roller 20. The support bearing seat 11 is connected to the upper support roller 30 and the lower support roller 40 respectively through bearings. The gap elimination device 50 is connected to the support bearing seat 11 and is used to translate along the direction close to or away from the thinning composite roller 20 to adjust and eliminate the fitting gap between the upper support roller 30, the lower support roller 40 and the thinning composite roller 20. Specifically, by placing the thinning composite roller 20 on the same side as the upper support roller 30 and the lower support roller 40, and symmetrically arranging the upper support roller 30 and the lower support roller 40 to abut against the thinning composite roller 20, the problem of insufficient rigidity of the thinning roller caused by reducing the roller diameter to improve thinning efficiency is solved, thus preventing deformation when it is running at high speed or under processing load. The support bearing seat 11 provides a stable assembly base for the upper support roller 30 and the lower support roller 40 through the bearing, ensuring smooth rotation of the roller system. The clearance elimination device 50 is connected to the support bearing seat 11 and drives its translation, which can accurately adjust and eliminate the fitting clearance between the upper and lower support rollers 40 and the thinning composite roller 20, reduce the impact and vibration during the operation of the roller system, improve the processing accuracy and operational stability of the equipment, and extend the service life of the roller system.

[0022] like Figure 1 As shown, the main body 10 also includes a drive device 60, which is connected to the thinning composite roller 20 and is used to drive the thinning composite roller 20 to rotate. Specifically, the addition of the drive device 60 connected to the thinning composite roller 20 provides stable and continuous rotational power to the thinning composite roller 20, ensuring that the thinning composite roller 20 can operate at a preset speed, adapting to the thinning processing requirements of materials of different thicknesses. At the same time, the power transmission is direct, reducing energy loss and improving equipment operating efficiency.

[0023] like Figures 1 to 4As shown, the driving device 60 includes a connecting plate 61, a driving motor 62, a motor anti-rotation plate 63, a slider 64, and a linear guide rail 65. One end face of the connecting plate 61 is fixedly connected to the driving motor 62, and the other end is assembled and connected to the linear guide rail 65. The output end of the driving motor 62 passes through the connecting plate 61 and is connected to the thinning composite roller 20. One end of the motor anti-rotation plate 63 is fixedly connected to the support bearing seat 11, and the other end is connected to an expansion sleeve 66. The slider 64 is connected to the end of the expansion sleeve 66 that is away from the motor anti-rotation plate 63. The linear guide rail 65 and the slider 64 are slidably engaged. Specifically, the drive unit 60 achieves a stable assembly of the drive motor 62 and the linear guide rail 65 through the connecting plate 61, ensuring the coaxiality of the power output end and the thinning composite roller 20; the motor anti-rotation plate 63 is fixedly connected to the support bearing seat 11 and connected to the slider 64 through the expansion sleeve 66, effectively preventing the drive motor 62 from rotating off-center during operation and improving the stability of power transmission; the sliding cooperation between the slider 64 and the linear guide rail 65 enables the drive unit 60 to adapt to the translational movement of the support bearing seat 11, ensuring uninterrupted power transmission and smooth operation during the backlash elimination adjustment process, further improving the overall reliability of the equipment operation.

[0024] like Figure 1 As shown, the thinning composite roller 20 has thinning bearing seats 21 connected to both ends of the roller via bearings. The thinning bearing seats 21 and the supporting bearing seats 11 form a guiding sliding fit. The thinning composite roller 20 passes through the thinning bearing seats 21 and is connected to the drive motor 62. A first thin-type hydraulic cylinder 22 is connected to the rear side of the thinning bearing seats 21 to drive the thinning bearing seats 21 to translate along a preset direction, thereby adjusting the position of the thinning composite roller 20. Specifically, the thinning composite roller 20 has thinning bearing seats 21 connected to both ends of the roller via bearings, and the thinning bearing seats 21 and the supporting bearing seats 11 form a guiding sliding fit, providing precise assembly guidance for the thinning composite roller 20 and ensuring its rotational accuracy. The first thin-type hydraulic cylinder 22 is connected to the rear side of the thinning bearing seats 21 and can drive the thinning bearing seats 21 to translate precisely along a preset direction, thereby realizing the fine adjustment of the position of the thinning composite roller 20. This can adapt to the position compensation requirements under different processing conditions and effectively improve the dimensional accuracy and consistency of material thinning processing.

[0025] like Figure 4As shown, a first scraper 23 is disposed on one side of the thinning composite roller 20. The blade surface of the first scraper 23 is adapted to the roller surface of the thinning composite roller 20 and is arranged in a close fit. The two ends of the first scraper 23 are respectively connected to a first adjusting cylinder (not shown in the figure). The first adjusting cylinder (not shown in the figure) is used to drive the first scraper 23 to move along the direction close to or away from the roller surface of the thinning composite roller 20, so as to adjust the fit gap between the scraper and the roller surface. A first waste guide plate 24 is provided on the side of the first scraper 23 away from the thinning composite roller 20. A first waste collection box 25 is arranged directly below the first waste guide plate 24. A first grip handle 26 is provided on both sides of the first waste collection box 25. Specifically, the first scraper 23 on one side of the thinning composite roller 20 is arranged with its blade surface adapted to and in close contact with the roller surface, which can scrape off the waste and impurities attached to the surface of the thinning composite roller 20 in real time, avoiding the waste from affecting the surface quality of the processed material and the precision of the roller system. The two first adjusting cylinders (not shown in the figure) arranged at both ends can drive the first scraper 23 to move in the direction close to or away from the roller surface of the thinning composite roller 20, and can precisely adjust the contact gap between the scraper and the roller surface according to the actual working conditions to adapt to different waste adhesion conditions, ensuring the cleaning effect while avoiding excessive wear of the scraper. The first waste guide plate 24 can accurately guide the scraped waste into the first waste collection box 25 below, realizing the centralized collection of waste and preventing waste from scattering and polluting the equipment or processing environment. The first grip handles 26 on both sides of the first waste collection box 25 facilitate operators to quickly pick up and put in the collection box, simplifying the waste cleaning process and improving equipment maintenance efficiency.

[0026] like Figure 6 As shown, a second scraper 31 is disposed on one side of the upper support roller 30. The blade surface of the second scraper 31 is adapted to the roller surface of the upper support roller 30 and is arranged in a close fit. A second adjusting cylinder 32 is connected to each end of the second scraper 31. The second adjusting cylinder 32 is used to drive the second scraper 31 to move along the direction close to or away from the roller surface of the upper support roller 30 to adjust the fit gap between the scraper and the roller surface. A second waste collection box 33 is disposed directly below the second scraper 31. A second grip handle 34 is provided on one side of the second waste collection box 33. Specifically, the second scraper 31 on one side of the upper support roller 30 can selectively scrape off waste and impurities from the surface of the upper support roller 30, ensuring the cleanliness of the roller surface and preventing uneven force on the thinning composite roller 20 due to foreign matter adhering to the roller surface; the two second adjusting cylinders 32 arranged at both ends can drive the second scraper 31 to move in a direction closer to or further away from the roller surface of the upper support roller 30, and can precisely adjust the contact gap between the scraper and the roller surface according to the actual working conditions to adapt to different waste adhesion conditions, ensuring cleaning effect while avoiding excessive wear of the scraper; the second waste collection box 33 is specially designed to collect the waste scraped off from the upper support roller 30, realizing classified collection, and the second grip handle 34 improves the convenience of picking up and putting down the collection box, further optimizing the equipment maintenance experience.

[0027] like Figure 4 and Figure 6 As shown, a third scraper 41 is disposed on one side of the lower support roller 40. The blade surface of the third scraper 41 is adapted to and arranged in a close fit with the roller surface of the lower support roller 40. A third adjusting cylinder 42 is connected to each end of the third scraper 41. The third adjusting cylinder 42 is used to drive the third scraper 41 to move along the direction close to or away from the roller surface of the lower support roller 40 to adjust the fit gap between the scraper and the roller surface. A second waste guide plate 43 is provided on the side of the third scraper 41 away from the lower support roller 40. The second waste guide plate 43 is adapted to and guides the first waste collection box 25 to guide the waste scraped off by the third scraper 41 into the first waste collection box 25. Specifically, the third scraper 41 on one side of the lower support roller 40 can effectively clean the roller surface of the lower support roller 40, ensuring the bonding accuracy between the lower support roller 40 and the thinning composite roller 20, and reducing processing errors caused by impurities on the roller surface; the two third adjusting cylinders 42 arranged at both ends drive the third scraper 41 to adjust the bonding gap, adapting to the operating conditions of the lower support roller 40 and the waste adhesion situation, improving the targeting and reliability of cleaning; the second waste guide plate 43 corresponds to and is adapted to the first waste collection box 25, guiding the waste scraped off by the third scraper 41 into the existing first waste collection box 25, realizing centralized waste collection without the need to add an additional independent collection box, saving equipment installation space, simplifying the waste handling process, and improving collection efficiency.

[0028] like Figure 1 As shown, two support bearing seats 11 are provided, respectively arranged on both ends of the upper support roller 30 and the lower support roller 40. Each support bearing seat 11 is simultaneously fitted and assembled with the corresponding end of the upper support roller 30 and the corresponding end of the lower support roller 40. Specifically, the two support bearing seats 11 are respectively arranged on both ends of the upper and lower support rollers 40, and each support bearing seat 11 is simultaneously fitted and assembled with the corresponding end of the upper and lower support rollers 40. This ensures the coaxiality assembly accuracy of the upper and lower support rollers 40, simplifies the assembly structure of the roller system, and reduces the number of parts. The symmetrically arranged support bearing seats 11 provide stable end support for the upper and lower support rollers 40, further enhancing the overall rigidity and running stability of the roller system, reducing the vibration amplitude during high-speed operation, and extending the service life of the roller system and bearings.

[0029] like Figure 1As shown, the backlash elimination device 50 includes a pressure cylinder 51 and a second thin cylinder 52; the pressure cylinder 51 is coaxially disposed in the center of the support bearing seat 11 and is used to apply the main pressure to the support bearing seat 11; there are two second thin cylinders 52, which are symmetrically arranged on both sides of the pressure cylinder 51 and are used to apply fine adjustment pressure to the support bearing seat 11 to correct its posture. Specifically, the gap elimination device 50 is configured in two sets, both of which adopt a combination design of pressure cylinder 51 and second thin cylinder 52. The pressure cylinder 51 is coaxially located in the center of the support bearing seat 11, which can apply stable main pressure to the support bearing seat 11 and quickly eliminate the initial gap between the rollers. The two second thin cylinders 52, which are symmetrically arranged on both sides of the pressure cylinder 51, can apply fine adjustment pressure to accurately correct the posture of the support bearing seat 11, avoid tilting during the translation of the support bearing seat 11, ensure the uniformity of the fit between the upper and lower support rollers 40 and the thinning composite roller 20, improve the gap elimination accuracy and the stability of the roller system, and reduce local wear on the roller surface.

[0030] like Figure 1 As shown, the pressure cylinder 51 is an AGC cylinder, used to improve the stability of the roll gap between the upper support roller 30, the lower support roller 40, and the thinning composite roller 20, and to simplify the gap adjustment operation. Specifically, the pressure cylinder 51 is selected as an AGC cylinder. Utilizing its high-precision pressure control and position adjustment characteristics, it can not only accurately provide the main pressure required for gap elimination, but also respond in real time to minute changes in the roll gap during processing, dynamically adjusting the pressure to maintain roll gap stability, effectively improving the thickness consistency of material thinning processing. At the same time, the integrated design of the AGC cylinder simplifies the complex operation process of traditional roll gap adjustment, reduces the adjustment difficulty for operators, and improves production efficiency and the controllability of processing quality.

[0031] The working principle of this invention is as follows: The upper support roller 30 and the lower support roller 40 are arranged symmetrically and abut against the same side of the thinning composite roller 20. Two support bearing seats 11 are respectively fitted to the two ends of the upper and lower support rollers 40, forming a stable roller support structure and significantly enhancing the rigidity of the thinning composite roller 20. When the clearance elimination device 50 is working, the central pressure cylinder 51 applies the main pressure to the support bearing seat 11, driving the support bearing seat 11 to move horizontally towards the thinning composite roller 20, initially eliminating the fit clearance between the rollers. Simultaneously, the second thin-type cylinders 52 on both sides apply fine-tuning pressure to correct the posture of the support bearing seat 11, ensuring uniform contact between the upper and lower support rollers 40 and the thinning composite roller 20. The drive device 60 fixes the drive motor 62 and the linear guide rail 65 through the connecting plate 61. The motor output end is connected to the thinning composite roller 20 to provide rotational power. The motor anti-rotation plate 63 is connected to the slider 64 through the expansion sleeve 66 to prevent the motor from rotating off-center. The slider 64 and the linear guide rail 65 slide... The dynamic coordination ensures that the drive device 60 can adapt to the backlash-free translational movement of the support bearing seat 11, achieving stable power transmission; the thinning bearing seats 21 at both ends of the thinning composite roller 20 are guided and slidably engaged with the support bearing seat 11, and the first thin-type hydraulic cylinder 22 drives the thinning bearing seat 21 to translate, precisely adjusting the position of the thinning composite roller 20 to adapt to different processing requirements; during the processing, the first scraper 23, the second scraper 31, and the third scraper 41 respectively adhere to the roller surfaces of the thinning composite roller 20, the upper support roller 30, and the lower support roller 40, scraping off surface waste in real time. The first waste guide plate 24 guides the waste from the thinning composite roller 20 to the first waste collection box 25, and the second waste guide plate 43 also guides the waste from the lower support roller 40 to the first waste collection box 25 for centralized collection. The waste from the upper support roller 30 falls into the second waste collection box 33. The operator can easily pick up and put down the collection box to clean the waste by holding the handle, thus achieving high-precision, stable, and convenient material thinning processing.

[0032] The above description merely illustrates preferred technical solutions of the present invention, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and the present invention also intends to include these modifications and variations.
