Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0032] Figures 1 to 4 The papermaking felt edge-sealing machine shown includes a worktable 1 and a fixing assembly 5. A machine body 2 is located on one side of the worktable 1, and a needle 3 is located on one side of the machine body 2. A limiting device 4 is located on one side of the worktable 1 via the fixing assembly 5. The limiting device 4 limits the edge of the felt through a limiting plate 44 and a pressing assembly 45. When sealing the papermaking felt, the limiting device 4 is fixed to one side of the worktable 1 via the fixing assembly 5. Then, the edge of the felt is placed on the worktable 1, and the edge is limited by the limiting assembly. The needle 3 at the upper end of the machine body 2 on the worktable 1 sews thread to the edge of the felt for sealing. The felt is then moved to complete the sealing of the entire edge area.
[0033] Figures 1 to 4The limiting device 4 shown includes a slide rail 41, a sliding block 42, a first bolt 43, a limiting plate 44, and a pressing component 45. The sliding block 42 slides inside the slide rail 41 to drive the limiting plate 44 to change its position. The first bolt 43 passes through the sliding block 42 and contacts the slide rail 41 to fix the positions of the sliding block 42 and the limiting plate 44. The pressing component 45 is located on the side of the limiting plate 44 near the needle 3 to flatten the upper end of the blanket that is attached to the edge of the limiting plate 44. Before using the limiting device 4, move the limiting plate 44 so that the sliding block 42, which is fixed to the limiting plate 44, slides inside the slide rail 41. Then, move the limiting plate 44 closer to or further away from the needle 3 so that the distance between the limiting plate 44 and the needle 3 matches the distance that the blanket needs to be sewn and sealed. Then, rotate the first bolt 43 so that the first bolt 43 passes through the sliding block 42 and abuts against the slide rail 41 to fix it, thus completing the fixation of the position of the sliding block 42 and the limiting plate 44. By using the limiting device 4, the blanket on the worktable 1 can be limited, so that the blanket can move more stably and avoid the position of the blanket shifting when it moves, which would affect the sealing effect, thereby improving the use effect of the sealing machine.
[0034] Figures 1 to 4 The pressing assembly 45 shown includes an extension plate 451, a spring 452, and a pressure plate 453. The extension plate 451 is located on the side of the limiting plate 44 away from the sliding block 42. The spring 452 is located on the side of the extension plate 451 closer to the worktable 1. The pressure plate 453 is located on the side of the extension plate 451 closer to the worktable 1. The spring 452 presses down the pressure plate 453 to flatten the edge of the blanket moving on the worktable 1. When the edge of the blanket is placed on the side of the limiting plate 44, the pressure plate 453 needs to be lifted. At this time, the spring 452 is compressed. Then, after the edge of the blanket is on the side of the limiting plate 44, the pressure plate 453 is released, and the spring 452 fixed on the side of the extension plate 451 will return to its original position, causing the pressure plate 453 to fit against the upper end of the blanket. When the blanket moves, the pressure plate 453 flattens the edge of the blanket, which facilitates the subsequent sewing and sealing of the blanket edge.
[0035] Figures 1 to 4A stabilizing rod 454 is fitted inside the spring 452, which restricts the shape of the spring 452. By fitting inside the spring 452, sliding within the extension plate 451, and fixing one end to the pressure plate 453, the stabilizing rod 454 restricts the shape of the spring 452, preventing bending and ensuring its continued usability. A guide plate 455 is provided on the side of the pressure plate 453 near the sliding block 42. The guide plate 455 is inclined on one side of the pressure plate 453 to increase the opening size on one side. By fixing the guide plate 455 to one side of the pressure plate 453, one end of the pressure plate 453 can be better inserted into the edge of the blanket, thus improving the usability of the pressure plate 453. An operating block 46 is provided on one side of the first bolt 43, which increases the size of one side of the first bolt 43. By fixing the operating block 46 to one side of the first bolt 43, the increased size of one side of the first bolt 43 makes it easier to rotate the first bolt 43. A rubber pad 47 is provided on the side of the slide rail 41 near the first bolt 43. The rubber pad 47 increases the friction on one side of the slide rail 41. By fixing the rubber pad 47 on one side of the slide rail 41, the friction between the first bolt 43 and the slide rail 41 is increased, so that the first bolt 43 can better abut and fix with the slide rail 41.
[0036] Figures 1 to 4 The fixing component 5 shown includes a square tube 51, a second bolt 52, a mounting plate 53, and a washer 54. The square tube 51 is located on one side of the workbench 1, and the mounting plate 53 is connected to the slide rail 41 on one side. The second bolt 52 fixes the mounting plate 53, which is inserted into the square tube 51. The washer 54 is located in the gap between the second bolt 52 and the square tube 51. When the limiting device 4 is in use, the mounting plate 53, which is fixed on one side of the slide rail 41, can be inserted into the square tube 51. Then, the second bolt 52 is rotated so that it passes through the washer 54 and the square tube 51 to reach the inside of the mounting plate 53. At this time, the washer 54 increases the contact area between the square tube 51 and the second bolt 52. Then, the second bolt 52 is threaded and fixed to the mounting plate 53, thus quickly fixing the position of the slide rail 41. By using the fixing component 5, the limiting component can be quickly installed and fixed to one side of the workbench 1, making it convenient for operators to use the limiting device 4 later.
[0037] Working principle: When sealing the edges of the papermaking felt, the limiting device 4 is fixed to one side of the worktable 1 by the fixing component 5. Then, the edge of the felt is placed on the worktable 1, and the edge of the felt is limited by the limiting component. Then, the needle 3 at the upper end of the machine body 2 of the worktable 1 sews the thread to the edge of the felt to seal it. Then, the felt is moved to complete the sealing of the entire edge area. Before using the limiting device 4, the limiting plate 44 is moved so that the sliding block 42 fixed to the limiting plate 44 slides inside the slide rail 41. Then, the limiting plate 44 is moved closer to or away from the needle 3 so that the distance between the limiting plate 44 and the needle 3 is adapted to the distance of the felt to be sealed. Then, the first bolt 43 is rotated so that the first bolt 43 passes through the sliding block 42 and abuts against the slide rail 41 to fix the position of the sliding block 42 and the limiting plate 44. When the edge of the felt is placed on one side of the limiting plate 44, the pressure plate 453 needs to be lifted. At this time, the spring 452 is compressed. After the edge of the blanket is on one side of the limiting plate 44, the pressure plate 453 is released, and the spring 452 fixed on one side of the extension plate 451 will reset, so that the pressure plate 453 will be in contact with the upper end of the blanket. When the blanket moves, the pressure plate 453 flattens the edge of the blanket, which makes it easier to sew and seal the edge of the blanket later. By using the limiting device 4, the blanket on the worktable 1 can be limited, so that the blanket can move more stably and avoid the position of the blanket shifting when it moves, which would affect the sealing effect, thereby improving the use effect of the sealing machine.
[0038] When the limiting device 4 is in use, the mounting plate 53 fixed on one side of the slide rail 41 can be inserted into the square tube 51, and then the second bolt 52 can be rotated so that the second bolt 52 passes through the washer 54 and the square tube 51 to reach the inside of the mounting plate 53. At this time, the washer 54 increases the contact area between the square tube 51 and the second bolt 52, and then the second bolt 52 is threaded to the mounting plate 53, and then the position of the slide rail 41 is quickly fixed. By using the fixing component 5, the limiting component can be quickly installed and fixed to one side of the workbench 1, and then it is convenient for the operator to use the limiting device 4 in the future.
