Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber reinforced plastic production equipment, in particular to a tension regulating device for a glass fiber line. Background Art

[0002] Fiberglass thread is a linear material made of glass fiber, which is made by processing extremely fine glass fiber filaments through a specific processing technology.

[0003] The existing Chinese patent application number CN202221772290.8 discloses a tension adjustment device and system for glass fiber yarn, including an adjuster; a ring buckle, the bottom of which is connected to the top of the adjuster; a support frame, which is respectively connected to a branch plate and a tension roller; a tension rod, the bottom of which is connected to the top of the support frame, and the tension rod abuts against the ring buckle through the glass fiber yarn. The glass fiber yarn is placed on the wire tube placement frame and fixed with a barb. The glass fiber yarn preferentially passes through the branch plate to prevent the glass fiber yarn from tangling during the weaving process. The glass fiber yarn passing through the branch plate passes through the ring buckle. The adjuster applies tension to the glass fiber yarn through its own weight. The glass fiber yarn then passes through the top of the tension rod. The tension rod is used to adjust the tension of the glass fiber yarn again. The glass fiber yarn passing through the top of the tension rod then passes through the bottom of the tension roller, marking the final adjustment of the glass fiber yarn tension.

[0004] In the above technology, the rotation of the tension roller is achieved by pulling the glass fiber line. During the pulling process, the glass fiber line generates a large friction with the tension roller and the tension rod, which can easily cause wear on the surface of the glass fiber line. Excessive friction can easily cause static electricity to be generated and accumulated on the outer surface of the glass fiber. The accumulation of static electricity not only easily attracts dust and other particles, affecting the cleanliness and appearance of the product, but also easily causes the fiber lines to attract each other, resulting in wire knotting, affecting production continuity and product quality.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example 1:

[0026] See also Figure 1-Figure 5The static elimination component 6 includes a first motor 61 fixedly connected to the bottom end of the inner wall of the first groove 11, a threaded rod 62 fixedly connected to the output end of the first motor 61, a first slider 63 threadedly connected to the outer surface of the threaded rod 62, a guide rod 64 fixedly connected to the inner wall of the second groove, a second slider 65 slidably connected to the outer surface of the guide rod 64, a second motor 66 fixedly connected to one side of the first slider 63, a first rotating shaft 67 fixedly connected to the output end of the second motor 66, a connecting column 68 rotatably connected to one side of the second slider 65, and a static elimination bar 69 movably arranged between the first rotating shaft 67 and the connecting column 68. The threaded rod 62 is rotatably connected to the top end of the inner wall of the first groove 11, and the threaded rod 62 is driven to rotate by the first motor 61, thereby performing The first slider 63 is driven to move up and down along the first groove 11. At this time, the second slider 65 slides along the guide rod 64 to play a guiding role. The movement of the first slider 63 and the second slider 65 drives the static elimination rod 69 to move up and down, which is convenient for adjusting the height of the static elimination rod 69, thereby facilitating fine-tuning the tension of the glass fiber line. The second motor 66 drives the first shaft 67 to rotate, thereby driving the static elimination rod 69 to rotate, so as to effectively contact and neutralize the static electricity on the outer surface of the glass fiber line. At the same time, when contacting the glass fiber line, it is convenient to reduce the friction between the wire and the static elimination rod 69, so that the glass fiber line is easier to be pushed through smoothly, reducing fiber damage or production blockage caused by large friction, and improving the continuity and stability of the production process.

[0027] One end of the first rotating shaft 67 is fixedly connected to the first mounting plate 671, and one end of the connecting column 68 is fixedly connected to the second mounting plate 681. Both ends of the static elimination rod 69 are fixedly connected to the connecting plates 691. A first locking bolt 6711 is threadedly connected between one group of connecting plates 691 and the first mounting plate 671, and a second locking bolt 6811 is threadedly connected between the other group of connecting plates 691 and the second mounting plate 681. When the static elimination rod 69 needs to be cleaned, inspected or replaced, the first locking bolt 6711 and the second locking bolt 6811 are loosened to facilitate quick disassembly of the static elimination rod 69.

[0028] A third motor 9 is fixedly connected to the outside of the connecting plate 3, and a second rotating shaft is fixedly connected to the output end of the third motor 9. The tension roller 7 is fixedly connected to the second rotating shaft. The second rotating shaft passes through the connecting plate 3, and the glass fiber line passes through the top of the tension roller 7. The tension roller 7 is driven to rotate by the third motor 9, which facilitates the pushing of the glass fiber line and reduces the friction between the wire and the tension roller 7.

[0029] A compression assembly 4 for compressing the glass fiber line is provided on the inner side of the connecting plate 3. The compression assembly 4 includes a connecting rod 41 passing through the top plate 31, a mounting bracket 42 fixedly connected to the bottom end of the connecting rod 41, a first rotating rod 43 rotatably connected to the inner side of the mounting bracket 42, and a pressure roller 44 fixedly connected to one end of the first rotating rod 43. The pressure roller 44 is in contact with the tension roller 7. The pressure roller 44 and the tension roller 7 facilitate compacting the glass fiber line at the top end of the tension roller 7, ensuring that the glass fiber line is stably transmitted at the top end of the tension roller 7 to prevent it from becoming loose.

[0030] A third groove 32 is provided on the inner side of the connecting plate 3, and a connecting block 421 is fixedly connected to the side of the mounting frame 42 close to the third groove 32. A first spring 321 is fixedly connected between the connecting block 421 and the top end of the inner wall of the third groove 32, and a second spring 322 is fixedly connected between the connecting block 421 and the bottom end of the inner wall of the third groove 32. The automatic expansion and contraction of the first spring 321 and the second spring 322 facilitates the adjustment of the pressure of the pressure roller 44 on the glass fiber line, thereby ensuring that the pressure is moderate and stable.

[0031] An anti-winding component 5 for preventing winding is provided at the top of the support plate 2. The anti-winding component 5 includes a fixed plate 51 fixedly connected to the top of the support plate 2, a second rotating rod 52 passing through the fixed plate 51, a fiber splitting plate 53 fixedly connected to the outer surface of the second rotating rod 52, and a limit block 54 movably connected to the outer surface of the second rotating rod 52. Fiber splitting grooves 531 are provided on the outer surface of the fiber splitting plate 53. There are multiple groups of fiber splitting grooves 531. Loosen the limit block 54 and rotate the second rotating rod 52 to drive the fiber splitting plate 53 to rotate, which is convenient for adjusting the angle of the fiber splitting plate 53. Passing the glass fiber line through the multiple groups of fiber splitting grooves 531 reduces the disorder and winding of the wire during processing.

[0032] During use, the glass fiber line first passes through the fiber splitter plate 53, and then passes through the multi-component fiber slot 531 to reduce the disorder and entanglement of the wire during the processing. The glass fiber line is then passed through the top of the tension roller 7 and the bottom of the static elimination rod 69 in sequence. The third motor 9 drives the tension roller 7 to rotate, which facilitates the pushing of the glass fiber line so that the glass fiber line is smoothly pushed through the tension roller 7. During this process, the automatic expansion and contraction of the first spring 321 and the second spring 322 facilitate the adjustment of the pressure of the pressure roller 44 on the glass fiber line. The first motor 61 drives the threaded rod 62 to rotate, thereby driving the first slider 63 and the second slider 65 to move up and down. The movement of the first slider 63 and the second slider 65 facilitates the adjustment of the height of the static elimination rod 69, thereby facilitating fine-tuning the tension of the glass fiber line. The second motor 66 drives the first rotating shaft 67 to rotate, thereby driving the static elimination rod 69 to rotate, facilitating effective contact and neutralization of static electricity on the outer surface of the glass fiber line. At the same time, when contacting the glass fiber line, it facilitates reducing the friction between the wire and the static elimination rod 69, thereby improving the continuity and stability of the production process.
