Abstract
Description
Technical Field
[0001] The invention relates to the technical field of polypropylene filament production, and in particular to an integrated device for winding and changing polypropylene filaments. Background Art
[0002] In the production process of polypropylene (PP) filament, winding and changing are the key links that determine the final quality of the product and production efficiency. Polypropylene filament is widely used in industrial ropes, filter materials, home textiles and other fields due to its light weight, high strength and corrosion resistance.
[0003] However, its smooth surface and low friction coefficient make it easy to slip and loosen the package during high-speed winding, which puts higher requirements on the stability and tension control of the winding equipment. Traditional winding and changing technology mostly adopts manual operation mode, which has the following significant defects: 1. Limited production efficiency: When changing rolls, the production line needs to be stopped, and then the winding roller needs to be replaced. However, the existing winding roller is often connected to the device by bolts and threads. When replacing it, it is often necessary to manually release the connection part of the winding roller with tools, and then disassemble it, which will greatly affect the disassembly speed and effect of the winding roller, and affect the winding roller replacement speed; 2. Loose winding: Due to the high elasticity of polypropylene filaments and the smooth surface of polypropylene, this will lead to the expansion of the roll body due to material rebound after winding and insufficient friction between layers, which will cause loose sliding. Summary of the invention

[0021] Reference Figure 1-Figure 7A polypropylene filament winding and changing integrated device comprises a mounting plate 2, the upper end of the mounting plate 2 is provided with two sets of connecting mechanisms, each set of connecting mechanisms comprises a moving groove 13, a mounting frame 1, a mounting groove 9, a mounting block 4, a press slot 29, a magnetic plug-in block 11 and a plug-in groove 19, the mounting frame 1 is fixedly connected to the upper end of the mounting plate 2, the mounting groove 9 and the moving groove 13 are both opened at one end of the mounting frame 1, the mounting block 4 is slidably connected to the mounting groove 9, the press slot 29 and the plug-in groove 19 are respectively opened in the upper inner portion of the moving groove 13 The magnetic plug-in block 11 is slidably connected to the movable groove 13, and the magnetic plug-in block 11 is movably plugged into the press slot 29 and the plug-in slot 19. One end of the mounting block 4 is rotatably connected to the winding roller 5 through the first bearing 30. A tensioning mechanism for preventing the polypropylene filament from loosening is provided on one side of the mounting frame 1. Each set of driving mechanisms includes an active groove 21, a screw rod 22, a second motor 23, a placement groove 25 and a screw rod nut 24. The active groove 21 is opened on the inner wall of one side of the movable groove 13, and the screw rod 22 is rotatable. The second motor 23 is fixedly connected to the mounting groove 25, and the output end of the second motor 23 is fixedly connected to the lower end of the screw rod 22, the screw nut 24 is threadedly connected to the circumferential surface of the screw rod 22, and the screw nut 24 is fixedly connected to the magnetic plug-in block 11. When the winding roller 5 needs to be disassembled, the second motor 23 is driven to rotate, and then its output shaft drives the screw rod 22 to rotate, and at this time, the screw nut 24 is threadedly connected to the circumferential surface of the screw rod 22. The connected lead screw nut 24 moves downward in the movable groove 21. After the magnetic attraction plug-in block 11 is completely pulled out of the pressing slot 29 and the mounting block 4, the magnetic attraction plug-in block 11 will release the magnetic connection with the mounting block 4, so the mounting block 4 can be easily pulled upward from the mounting groove 9, thereby replacing the winding roller 5. When installation is required, only the above steps need to be reversed to complete the installation of the winding roller 5. Through the above design, the replacement of the winding roller 5 is simpler and more efficient, shortening the required time and improving efficiency.
[0022] In particular, in the present invention, a placement groove 26 is provided at one end of one of the mounting frames 1, a first motor 16 is fixedly connected in the placement groove 26, a second gear 18 and a first gear 17 are fixedly connected to the output end of the first motor 16 and the circumferential surface of the first bearing 30, respectively, the tensioning mechanism comprises a spring 14, a mounting column 6, a connecting rod 7, a connecting frame 8, two second bearings 31 and a tensioning roller 12, the spring 14 is fixedly connected to one end of another mounting frame 1, the mounting column 6 is fixedly connected to one end of the spring 14, the connecting rod 7 is fixedly connected to one end of the mounting column 6, the connecting frame 8 is fixedly connected to one end of the connecting rod 7, and the tensioning roller 12 is connected to the second bearing 31 through two second bearings 31. The bearing 31 is rotatably connected to the connecting frame 8. When the winding roller 5 is required to be wound up, the first motor 16 is started to rotate its output shaft and drive the second gear 18 to rotate. At this time, the first gear 17 meshing therewith drives the first bearing 30 and the winding roller 5 to rotate, thereby winding up the polypropylene filament. Through the elasticity of the spring 14, the spacing between the tensioning roller 12 and the connecting frame 8 and the winding roller 5 can be adjusted. When the winding roller 5 is gradually wound up, the thickness of the polypropylene filament will gradually increase, and the tensioning roller 12 will maintain the contact with the polypropylene filament, thereby preventing the polypropylene filament from loosening during winding and improving the winding stability.
[0023] It should be noted that one end of the other mounting frame 1 is fixedly connected to a telescopic rod 15, a spring 14 is sleeved on the circumferential surface of the telescopic rod 15, a mounting circular plate 28 is fixedly connected to the connection between the connecting frame 8 and the connecting rod 7, and the mounting circular plate 28 is connected to one end of the connecting frame 8 by a threaded connection, a fixing groove 20 is provided at one end of the magnetic plug-in block 11 and the mounting block 4, a threaded rod 10 is threadedly connected to the fixing groove 20, and a nut 27 is fixedly connected to one end of the threaded rod 10, and a plurality of connecting holes 3 are provided at the lower end of the mounting plate 2, through which a plurality of connecting holes 3 are provided. The telescopic rod 15 can prevent the spring 14 from being damaged due to bending and deformation. The connecting rod 7 and the connecting frame 8 can be fixed and installed more stably by installing the circular plate 28. The mounting block 4 can be more firmly fixed in the mounting groove 9 and the outer surface of the magnetic plug-in block 11 through the threaded connection between the threaded rod 10 and the fixing groove 20. The threaded connection of the threaded rod 10 can facilitate the rotation and threaded connection of the threaded rod 10. The mounting plate 2 and the multiple connecting holes 3 opened at its upper end can facilitate the installation and connection of the mounting plate 2 and the part to be installed.
[0024] The working principle of the present invention is as follows: during use, when the winding roller 5 needs to be disassembled, the second motor 23 is driven to rotate, and then its output shaft drives the lead screw 22 to rotate. At this time, the lead screw nut 24 threadedly connected thereto moves downward in the movable groove 21. After the magnetic attraction plug-in block 11 is completely pulled out of the pressing slot 29 and the mounting block 4, the mounting block 4 can be easily pulled upward from the mounting slot 9 because the magnetic attraction plug-in block 11 will release the magnetic connection with the mounting block 4, thereby replacing the winding roller 5. When installation is required, the above steps only need to be reversed to complete the installation of the winding roller 5. Through the above design, the replacement of the winding roller 5 is simpler and more efficient, shortening the required time and improving efficiency.
