Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic substrate glass transportation, in particular to a synchronous paper feeding mechanism. Background Art

[0002] When photovoltaic substrate glass is successfully manufactured by a supplier and shipped to the next manufacturer, in order to prevent scratches and other damages caused by direct contact during transportation, a layer of paper will be placed between the two pieces of photovoltaic substrate glass to prevent direct wear of the glass. This is how paper laying machines came into being.

[0003] Patent No. CN112978390B discloses an automated paper laying machine for glass stacking. By combining a paper placing mechanism with a flattening mechanism, the paper is flattened and laid over the glass, preventing wrinkles and gaps between the two panes of glass. This can easily damage the glass during transport. However, conventional paper laying machines have a significant problem: excessively large sheets of paper often shift during laying, resulting in poor laying and requiring readjustment. To address this, we propose a synchronized paper feeding mechanism. Utility Model Content

[0035] See also Figure 1-Figure 7A synchronous paper feeding mechanism includes a workbench 1, a pressure wheel assembly 5 and a supporting wheel assembly 6. The supporting wheel assembly 6 is installed on the workbench 1, and the supporting wheel assembly 6 is used to support the pressure wheel 9. The workbench 1 is fixedly connected to the support frame 2, and the support frame 2 is rotatably connected to the paper reel 3. The workbench 1 is also fixedly connected to the frame 4. The pressure wheel assembly 5 is installed on the frame 4, and the pressure wheel assembly 5 includes multiple groups of servo motors 7 installed on one side of the frame 4. The output end of the servo motor 7 is connected to the servo reduction motor 8, and the output end of the servo reduction motor 8 is connected to the pressure wheel 9. The pressure wheel assembly 5 rotates the multiple groups of pressure wheels 9 by starting the servo motor 7, and the paper on the paper reel 3 is transported by the rotation of the pressure wheel 9, and cooperates with the servo reduction motor 8 The speed adjustment changes the speed of multiple groups of pinch rollers 9. The angle of the paper can be adjusted by adjusting the speed. The pinch roller 9 is lifted by the support roller assembly 6. During the paper conveying process, the pinch roller 9 is rotated by the servo motor 7 and the servo reduction motor 8, and the paper is conveyed by the rotation of the pinch roller 9. When the paper deviates during the conveying process, the speed of the servo reduction motor 8 on both sides of the frame 4 is controlled to make the speed of the pinch rollers 9 on both sides inconsistent. When the paper deviates to the right, the speed of the pinch roller 9 on the left is lower than that of the right pinch roller 9. The conveying angle of the paper is corrected by the difference in speed. Otherwise, the speed of the pinch roller 9 on the left is greater than that of the right pinch roller 9.

[0036] In the embodiment of the present application, the pressure wheel assembly 5 includes multiple groups of support plates 10 slidably connected to the frame 4, an adjusting member 11 connected to the frame 4 is installed on one side of the support plate 10, and a swing arm bracket 12 is fixedly connected to the other side of the support plate 10, the swing arm bracket 12 is rotatably connected to a rotating shaft 13, and the rotating shaft 13 is fixedly connected to a swing arm 14 fixedly connected to the servo reduction motor 8, and a rotating member 15 for driving the swing arm 14 to rotate is installed on the swing arm 14, and the rotating member 15 is connected to the support plate 10, and the rotating The component 15 includes a telescopic rod 16 fixedly connected to the support plate 10, the top of the telescopic rod 16 is fixedly connected to a connecting column 17 slidably connected to the swing arm 14, the swing arm 14 is provided with a movable groove 18 adapted to the connecting column 17, and the top of the connecting column 17 is fixedly connected to a movable block 19 movably connected to the swing arm 14, the roller assembly 6 includes a support seat 32 fixedly connected to the workbench 1, the support seat 32 is rotatably connected to a rotating roller 33, and the rotating roller 33 is fixedly connected to a plurality of groups of rollers 34, the number of which is greater than The number of pinch rollers 9 is set. During the paper conveying process, the pinch roller 9 rotates normally to convey the paper. When the width of the substrate glass changes, the required paper width is also inconsistent. The paper needs to be replaced, and the positions of multiple sets of pinch rollers 9 are adjusted at the same time. During the paper replacement process, paper of appropriate width is placed on the paper winding roller 3. At this time, the telescopic rod 16 contracts to move the connecting column 17. The swing arm 14 is pulled to rotate through the action of the connecting column 17 and the movable block 19, thereby causing the servo reduction motor 8 and the pinch roller 9 to rotate away from the support roller 34, thereby facilitating the placement of the paper between the support roller 34 and the pinch roller 9. After that, the telescopic rod 16 is reset to reset the pinch roller 9 to convey the paper normally. After that, the position of the pinch roller 9 needs to be adjusted according to the width of the paper. During the adjustment process, the position of the support plate 10 is adjusted through the action of the adjusting member 11, so that the position of the pinch roller 9 moves with the support plate 10, so that the two outermost sets of pinch rollers 9 can press on both sides of the paper, and the remaining pinch rollers 9 are arranged as evenly as possible.

[0037] In the embodiment of the present application, the adjusting member 11 includes a sliding block 20 fixedly connected to the support plate 10, the sliding block 20 is slidably connected to the frame 4, and a sliding groove 25 adapted to the sliding block 20 is provided on the frame 4, a spring 21 is fixedly connected to the sliding block 20, the end of the spring 21 is fixedly connected to a sliding column 22 slidably connected to the sliding block 20, the end of the sliding column 22 is rotatably connected to a ball 23 movably connected to the frame 4, a ball groove 24 adapted to the ball 23 is provided on the frame 4, and a reinforcement 26 for fixing the sliding block 20 is also installed on the sliding block 20, the reinforcement 26 includes a slide rail 27 fixedly connected to the frame 4, and a plurality of groups of threaded blocks 28 are slidably connected in the slide rail 27, and the number of threaded blocks 28 is the same as that of the sliding The number of blocks 20 is the same, and a threaded column 29 is threadedly connected to the threaded block 28, and the top of the threaded column 29 is fixedly connected to the rotating block 30. During the adjustment process, the support plate 10 slides by sliding the sliding block 20. During the sliding process of the sliding block 20, the ball 23 will squeeze the spring 21 to cause the ball 23 to shrink. After the position is determined, the ball 23 is pushed into the ball groove 24 again due to the action of the spring 21 to initially limit the sliding block 20. Then, the threaded column 29 corresponds to the sliding block 20 through the movement of the threaded block 28. At this time, the rotating block 30 rotates to drive the threaded column 29 to rotate, so that the threaded column 29 squeezes the sliding block 20. Therefore, the sliding block 20 is reinforced by the squeezing effect, thereby improving its stability during operation.

[0038] In some embodiments, the bottom end of the threaded column 29 is fixedly connected to an anti-skid pad. The anti-skid pad improves the friction between the threaded column 29 and the sliding block 20, thereby facilitating the reinforcement of the sliding block 20.

[0039] In some embodiments, the outer side of the rotating block 30 is provided with anti-slip grooves to increase the friction between the rotating block 30 and the hand, thereby facilitating the rotation of the rotating block 30 .

[0040] In some embodiments, two groups of springs 21 and balls 23 are provided, so that the resistance of the sliding block 20 when adjusting the position is increased, thereby making the sliding block 20 more stable and not randomly displaced.

[0041] In some embodiments, there are multiple groups of support seats 32, and all of them are rotatably connected to the rotating roller 33. The rotating roller 33 in this solution is relatively long, so multiple groups of support seats 32 are provided to improve the stability of the rotating roller 33.

[0042] During the implementation process, when conveying paper, appropriate paper is selected according to the width of the substrate glass. The width of the paper required for different substrate glass widths is also inconsistent, and the paper needs to be replaced, and at the same time, the positions of multiple sets of pinch rollers 9 need to be adjusted so that the outermost pinch roller 9 can press on the edge of the paper. In the process of replacing the paper, the paper of appropriate width is placed on the paper reel 3. At this time, the telescopic rod 16 contracts to move the connecting column 17. The swing arm 14 is pulled to rotate through the action of the connecting column 17 and the movable block 19, thereby causing the servo reduction motor 8 and the pinch roller 9 to rotate away from the support roller 34, and the paper is wound. It is convenient to place the paper between the support roller 34 and the pinch roller 9, and then the telescopic rod 16 is reset to reset the pinch roller 9. At this time, the paper is between the pinch roller 9 and the support roller 34. Then the position of the pinch roller 9 needs to be adjusted according to the width of the paper. During the adjustment process, the sliding of the sliding block 20 causes the support plate 10 to slide, and the position of the pinch roller 9 moves with the support plate 10. During the sliding process of the sliding block 20, the ball 23 will squeeze the spring 21 to make the ball 23 contract. After the position is determined, the two outermost groups of pinch rollers 9 can be pressed on both sides of the paper, and the remaining pinch rollers 9 are arranged as evenly as possible. , the ball 23 is pushed into the ball groove 24 again due to the action of the spring 21 to initially limit the sliding block 20, and then the threaded column 29 is made to correspond to the sliding block 20 through the movement of the threaded block 28. At this time, the rotation of the rotating block 30 drives the threaded column 29 to rotate, so that the threaded column 29 squeezes the sliding block 20, thereby reinforcing the sliding block 20 through the squeezing effect, improving its stability during work, and then starts to transport paper. At this time, the servo motor 7 is started, and the paper pressing wheel 9 is rotated by the action of the servo motor 7 and the servo reduction motor 8. At this time, the paper pressing wheel 9 and the supporting roller 34 cooperate correctly The paper is often conveyed, and the speed of laying the paper can be more simply controlled according to the speed of the servo reduction motor 8. When the paper deviates during the conveying process, the speed of the servo reduction motor 8 on both sides of the frame 4 is controlled to make the speed of the pressure rollers 9 on both sides inconsistent. When the paper deviates to the right, the speed of the pressure roller 9 on the left is lower than that of the pressure roller 9 on the right. The conveying angle of the paper is corrected by the difference in speed. On the contrary, the speed of the pressure roller 9 on the left is greater than that of the pressure roller 9 on the right. Then, the deviated paper is corrected by controlling the speed of the servo reduction motor 8.

[0043] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and illustrated in the embodiments.
