[0001] The invention belongs to the technical field of sandpaper production, and in particular relates to an automatic deviation-correcting sand-planting device for sandpaper production. Background Art

[0002] As an important abrasive tool, sandpaper is widely used in industrial production and daily life. It is mainly used for grinding, polishing and deburring various materials to improve the surface quality and precision of the materials. Sandpaper is an indispensable tool in metal processing, wood processing, automobile manufacturing, furniture manufacturing, electronics industry and other fields.

[0003] The sandpaper planting process is one of the key links that determine the quality of sandpaper. High-quality sandpaper planting should ensure that the abrasive particles are evenly and firmly attached to the sandpaper base to achieve good grinding performance. However, since the sandpaper planting process involves multiple links and factors, such as abrasive placement, adhesive coating, conveying speed, etc., various problems are prone to occur, among which deviation is one of the important issues affecting sandpaper planting quality and production efficiency.

[0004] However, in the process of conveying the existing sandpaper forward, the sandpaper may have position deviation or the tension at both ends of the sandpaper may be different, the sandpaper may move or the sandpaper may be wrinkled, resulting in uneven spraying of abrasive particles during the sanding process of the sandpaper, resulting in poor sanding effect of the sandpaper.

[0008] The sandpaper is conveyed forward to correct the left and right positions, and the sandpaper conveyed forward is placed in a middle position to ensure the accuracy of the sandpaper during the conveying and sand planting process, and the position of the sandpaper will not deviate due to the sandpaper shifting to one side or the other.

[0009] Furthermore, the sandpaper limiting component includes a limiting plate, a lower bearing plate and an upper bearing plate, the lower bearing plate and the upper bearing plate are symmetrically arranged on the correction plate, the upper bearing plate is provided with a limiting electric cylinder, and the limiting plate and the correction plate are slidably fitted on the telescopic end of the limiting electric cylinder.

[0010] Furthermore, a moving space for sandpaper to move is provided between the upper bearing plates.

[0011] Furthermore, the tension correction assembly includes an installation frame, an adjusting motor, an adjusting screw, a correction wheel and an adjusting block.

[0012] According to the tension of the sandpaper detected by the two tension detection sensors, the rotation of the corresponding adjustment motors on both sides can be controlled, so that the tension on both sides of the sandpaper is the same, ensuring that the tension of the sandpaper is consistent during the conveying process, and will not cause the sandpaper to wrinkle.

[0013] Furthermore, the sand planting conveying assembly includes a conveying seat, a lower conveying roller and an upper conveying roller, the conveying seat is vertically arranged, the upper conveying roller and the lower conveying roller are symmetrically rotatably connected to the conveying seat, the conveying seat is provided with a conveying motor that is transmission-connected to the lower conveying roller, and the lower conveying roller is provided with two installation spaces.

[0018] Secondly, when the present invention adjusts the tension of sandpaper and the position of sandpaper, the sandpaper rotates on the top of the two correcting wheels to adjust the position height of the correcting wheels. At this time, the adjusting motor drives the adjusting screw to rotate on the mounting frame, which can drive the adjusting block to move up and down on the limiting rods at both ends of the mounting frame, thereby driving the position of the vertical plate to move up and down, thereby causing the position of the correcting wheel to move up and down. The upward movement of the correcting wheel will increase the tension of the sandpaper, and the downward movement of the correcting wheel will reduce the tension of the sandpaper. During use, the rotation of the adjusting motors on the corresponding two sides can be controlled according to the tension detected by the two tension detection sensors on the sandpaper, so that the tension on both sides of the sandpaper is the same, ensuring that the tension of the sandpaper during the transportation process remains consistent, and will not cause wrinkling of the sandpaper.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] Reference Figures 1 to 8As shown, an embodiment of the present invention provides an automatic deviation correction and sand planting device for sandpaper production, comprising a deviation correction seat 1, left and right deviation correction components 2, a tension deviation correction component 3 and a sand planting and conveying component 4, the deviation correction seat 1 is horizontally arranged, the left and right deviation correction components 2 are arranged on the deviation correction seat 1, the left and right deviation correction components 2 are slidably matched with the deviation correction seat 1, two tension deviation correction components 3 are provided, the two tension deviation correction components 3 are horizontally arranged and a mounting seat 30 is provided underneath, and the two tension deviation correction components 3 respectively perform deviation correction movements on the two ends of the sandpaper; the sand planting and conveying component 4 is located beside the two tension deviation correction components 3, and a tension detection structure is provided on the sand planting and conveying component 4.

[0033] Specifically, the left and right correction components 2 include a rotating motor 21, a rotating gear 22, two correction plates 23 and two rotating tooth plates 24. The rotating motor 21 is located on the correction seat 1, and the rotating gear 22 is located on the main shaft of the rotating motor 21. The two rotating tooth plates 24 are symmetrically slidably connected to the correction seat 1. The rotating gear 22 is meshed with the two rotating tooth plates 24. Each of the correction plates 23 is respectively provided with two sliding rods 25, and the two sliding rods 25 are horizontally slidably connected to the correction seat 1. The two rotating tooth plates 24 are respectively connected to the two correction plates 23, and each of the correction plates 23 is provided with a sandpaper limiter 5.

[0034] When correcting the left and right positions of the sandpaper, the rotating motor 21 drives the rotating gear 22 to rotate, which drives the two rotating tooth plates 24 to move relative to each other or toward each other, thereby driving the two correcting plates 23 to move horizontally on the correcting seat 1 through the corresponding two sliding rods 25, so that the moving space 54 formed on the upper supporting plate 53 and the lower supporting plate 52 contacts the two ends of the sandpaper, and the sandpaper is conveyed forward to correct the left and right positions, and the sandpaper conveyed forward is in the middle position, ensuring the accuracy of the sandpaper during the conveying and sand planting process, and the position of the sandpaper will not deviate due to the sandpaper moving to one side or the other.

[0035] Specifically, the sandpaper limiting member 5 includes a limiting plate 51, a lower bearing plate 52 and an upper bearing plate 53. The lower bearing plate 52 and the upper bearing plate 53 are symmetrically arranged on the correction plate 23. The upper bearing plate 53 is provided with a limiting electric cylinder 55. The limiting plate 51 and the telescopic end of the limiting electric cylinder 55 are slidably matched with the correction plate 23.

[0036] During use, the limit electric cylinder 55 drives the movable plate to move on the correction plate 23, which will change the size and position of the movable space 54, so that during the transportation of the sandpaper, the distance thickness between the limit plate 51 and the lower bearing plate 52 can be adjusted according to the thickness of the sandpaper, ensuring that the sandpaper will not warp during the transportation process, affecting the quality of the sandpaper transportation and resulting in poor effect of the subsequent sandpaper planting.

[0037] Specifically, a moving space 54 for the sandpaper to move is provided between the upper bearing plates 53 ; when the positions of the two ends of the sandpaper are corrected and adjusted, the sandpaper moves forward horizontally in the moving space 54 .

[0038] Specifically, the tension correction assembly 3 includes a mounting frame 31, an adjusting motor 32, an adjusting screw 33, a correction wheel 34 and an adjusting block 35. The mounting frame 31 is vertically arranged at the top of the mounting seat 30, the adjusting screw 33 is rotatably connected to the mounting frame 31, the adjusting motor 32 is located at the top of the mounting frame 31 and is transmission-connected to the adjusting screw 33, two symmetrically arranged limit rods 37 are arranged in the mounting frame 31, the adjusting block 35 is threadedly connected to the adjusting screw 33 and slidably cooperates with the two limit rods 37, a vertically arranged vertical block 36 is arranged on the top of the adjusting block 35, and the correction wheel 34 is horizontally rotatably connected to the vertical block 36.

[0039] When the tension of the sandpaper and the position of the sandpaper are adjusted, the sandpaper rotates on the top of the two correcting wheels 34 to adjust the position height of the correcting wheels 34. At this time, the adjusting motor 32 drives the adjusting screw rod 33 to rotate on the mounting frame 31, which can drive the adjusting block 35 to move up and down on the limit rods 37 at both ends of the mounting frame 31, thereby driving the position of the vertical plate to move up and down, so that the position of the correcting wheel 34 moves up and down. The upward movement of the correcting wheel 34 will increase the tension of the sandpaper, and the downward movement of the correcting wheel 34 will reduce the tension of the sandpaper. During use, the rotation of the adjusting motors 32 on the corresponding two sides can be controlled according to the tension detected by the two tension detection sensors 6 on the sandpaper, so that the tension on both sides of the sandpaper is the same, ensuring that the tension of the sandpaper is consistent during the transportation process, and will not cause the sandpaper to wrinkle.

[0040] During the adjustment process, the adjusting block 35 is threadedly connected to the adjusting screw 47.

[0041] The rotation of the adjusting screw 47 can achieve a small and precise displacement adjustment. By precisely controlling the rotation angle and direction of the screw, the tension of the sandpaper can be finely adjusted to ensure that the tension value is stable within the ideal range; in some precision processing occasions that require extremely high tension on the sandpaper, the screw adjustment can meet the high-precision tension control requirements to ensure that the sandpaper always maintains a moderate tension during the conveying process, avoiding deformation and breakage of the sandpaper due to excessive tension, or loosening and deviation due to insufficient tension.

[0042] The adjusting screw 47 can be adjusted continuously and gradually according to actual needs. During the sandpaper conveying process, as the production conditions change, such as the change of sandpaper material and thickness, the adjustment of conveying speed, etc., the tension can be fine-tuned in real time by turning the adjusting screw 47 to adapt to the new production requirements. This continuous fine-tuning feature makes the production process more flexible, can respond to various changes in a timely manner, and ensure the stability and reliability of sandpaper conveying.

[0043] Specifically, the sand planting conveying assembly 4 includes a conveying seat 41, a lower conveying roller 42 and an upper conveying roller 43. The conveying seat 41 is vertically arranged, and the upper conveying roller 43 and the lower conveying roller 42 are symmetrically rotatably connected to the conveying seat 41. The conveying seat 41 is provided with a conveying motor 48 that is transmission-connected to the lower conveying roller 42, and the lower conveying roller 42 is provided with two installation spaces 44.

[0044] During the conveying process of sandpaper, the conveying motor 48 drives the lower conveying roller 42 to rotate on the conveying seat 41, thereby driving the sandpaper to move forward and cooperate with the rotation of the upper conveying roller 43 to continuously move the sandpaper forward for sand planting. The two tension detection sensors 6 on the lower conveying roller 42 can detect the tension on the conveyed sandpaper to ensure that the tension on both sides of the sandpaper is the same, and will not cause the sandpaper to deform, wrinkle or break, affecting the subsequent sand planting work of the sandpaper.

[0045] Specifically, the tension detection structure includes two annular tension detection sensors 6, and the two tension detection sensors 6 are respectively arranged in two installation spaces 44. The model of the tension detection sensor 6 is BLH NOBEL KIS-2.

[0046] The two tension detection sensors 6 can detect the tension on the sandpaper that needs to be sanded in real time, and correct the deviation by adjusting the tension of the sandpaper. If the tension on one side of the sandpaper is too large, it will cause deviation to the other side. The tension on both sides of the sandpaper can be balanced by adjusting the speed of the deviation correction wheel 34 or the tension device.

[0047] For example, increase the tension on one side of the deviation or reduce the tension on the other side to keep the sandpaper stable during transportation.

[0048] Specifically, two sliding blocks 45 are respectively provided at both ends of the upper conveying roller 43, and a slide groove 46 for sliding cooperation of the sliding blocks 45 is provided on the conveying seat 41. The upper conveying roller 43 is rotatably connected with the two sliding blocks 45, and an adjusting screw 47 rotatably connected to the top of the sliding block 45 is provided on the conveying seat 41, and the adjusting screw 47 is threadedly connected to the conveying seat 41.

[0049] When sanding sandpapers of different thicknesses, it is necessary to adjust the spacing distance between the upper conveying roller 43 and the lower conveying roller 42. At this time, the two adjusting screws 47 can be rotated respectively to drive the two sliding blocks 45 to move up and down in the two sliding grooves 46 respectively. The up and down movement of the two sliding blocks 45 will drive the position of the upper conveying roller 43 to move, thereby ensuring that during the conveying of the sandpaper, the upper conveying roller 43 can contact the top of the sandpaper, and the conveying motor 48 drives the lower conveying roller 42 to rotate to convey the sandpaper forward, thereby performing the sanding work on the sandpaper.

[0050] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
