[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0030] like Figure 1 - Figure 7 As shown, a fiberglass bundling device for producing tubular yarn includes an operating structure 1. Movable structures 2 are bolted to both sides of the top of the operating structure 1. A collecting structure 3 is bolted to the outer wall of the movable structure 2. A drawing machine 5 is bolted to the top of the operating structure 1, and a bundling structure 4 is bolted to the bottom of the operating structure 1. The operating structure 1 includes an operating platform 11 bolted to the bottom of the drawing machine 5. The bundling structure 4 includes a No. 4 drive motor 41 bolted to the bottom of the operating platform 11. One end of the No. 4 drive motor 41 is connected to a bundling disk 42. A bundling column 43 is welded to the outer wall of the top of the bundling disk 42. The collecting structure 3 includes a collecting frame 31, and a shovel plate 32 is bolted to the bottom of the collecting frame 31.
[0031] It should be noted that in this embodiment, the glass fiber produced inside the drawing machine 5 is stretched out and initially guided through the clamping column 44. Then, the fourth drive motor 41 is started, which drives the bundling disk 42 to rotate. The bundling disk 42 drives the bundling column 43, so that the glass fiber will wrap around the outer wall of the two bundling columns 43 and be collected. The moving structure 2 drives the shovel plate 32 to move and control it, so that the shovel plate 32 removes the glass fiber from the outer wall of the bundling column 43.
[0032] A clamping post 44 is bolted to the center of the top of the cluster disk 42. A motor 441 is bolted to the inner side of the bottom of the clamping post 44. One end of the motor 441 is connected to a rotating disk 442. A rotating post 443 is rotatably connected to the outer wall of one side of the rotating disk 442. A sliding rod 444 is slidably connected to the inner side of the rotating post 443. A limit plate 446 is fixedly sleeved on the outer wall of one end of the sliding rod 444. Limit grooves 445 are formed on the outer wall of the inner side of the bottom of the clamping post 44 and on the outer wall at both ends of the sliding rod 444. A bolt is bolted to the outer wall of the top of the sliding rod 444. A rubber bottom pressure block 449 is installed. A toothed block 4461 is welded to one side of the inner top of the limiting plate 446. A third rotating rod 447 is rotatably connected to the inner top of the clamping column 44. A synchronous gear 4471 is fixedly sleeved on the outer wall of the third rotating rod 447 and located inside the limiting plate 446. A pressure plate 448 is fixedly sleeved on the outer wall of the third rotating rod 447 and located on one side of the synchronous gear 4471. A rubber top pressure block 4481 is bolted to the middle of the bottom of the pressure plate 448. A rubber bottom pressure block 449 is bolted to the inner side of the outer wall of the clamping column 44.
[0033] It should be noted that in this embodiment, the starting motor 441 drives the rotating disk 442 to rotate, which in turn controls the rotating column 443 to move the slide rod 444 up and down. At the same time, both ends of the slide rod 444 are limited inside the limiting groove 445, thereby driving the limiting plate 446 to move up and down. When the limiting plate 446 moves up and down, the toothed block 4461 on the inner side of the top of the limiting plate 446 meshes with the synchronous gear 4471 on the outer wall of the third rotating rod 447, thereby controlling the rotation direction of the third rotating rod 447, raising the pressure plate 448, and then placing the fiberglass thread into the upper surface of the rubber bottom pressure block 449. At the same time, the starting motor 441 rotates in the opposite direction, controlling the pressure plate 448 to drive the rubber top pressure block 4481 to press the fiberglass thread on the upper surface of the rubber bottom pressure block 449.
[0034] A motor frame 311 is bolted to the bottom of the inner side of the top of the collection rack 31. A third drive motor 312 is bolted to the top of the motor frame 311. A transmission rod 313 is connected to one end of the third drive motor 312, located on the inner side of the bottom of the motor frame 311. A first helical gear 314 is welded to one end of the transmission rod 313, located at the bottom of the collection rack 31. An adjusting frame 33 is bolted to the bottom of the collection rack 31. A first rotating rod 331 is rotatably connected to the inner side of the outer wall of the adjusting frame 33. A fifth helical gear 339 is fixedly sleeved on the outer wall of the first rotating rod 331. The outer wall of the fifth helical gear 339 meshes with the outer wall of the transmission rod 313. A second helical gear 332 is fixedly sleeved on one end of the first rotating rod 331. Two second rotating rods 335 are rotatably connected to the inner side of the outer wall of the adjustment frame 33 and on the left and right sides of the lower surface of the first rotating rod 331. One end of the second rotating rod 335 on the left is fixedly sleeved with a fourth inclined gear 334, and one end of the second rotating rod 335 on the right is fixedly sleeved with a third inclined gear 333. The outer wall of the third inclined gear 333 meshes with the outer wall of the fourth inclined gear 334. The outer wall of the second inclined gear 332 meshes with the outer wall of the third inclined gear 333. A clamping plate 336 is fixedly sleeved in the middle of the second rotating rod 335 and located inside the adjustment frame 33. An anti-slip block 337 is bolted to the outer wall of one side of the clamping plate 336. A scissor blade 338 is bolted to the end of the second rotating rod 335 away from the second rotating rod 335.
[0035] It should be noted that in this embodiment, by starting the No. 3 drive motor 312, the transmission rod 313 is driven to rotate, causing the outer wall of the No. 1 inclined gear 314 at its bottom to mesh with the outer wall of the No. 5 inclined gear 339, thereby controlling the rotation of the No. 1 rotating rod 331. When the No. 1 rotating rod 331 rotates, it drives the outer wall of the No. 2 inclined gear 332 to mesh with the outer wall of the No. 3 inclined gear 333. When the No. 3 inclined gear 333 meshes with the No. 2 inclined gear 332, the outer wall of the No. 3 inclined gear 333 meshes with the outer wall of the No. 4 inclined gear 334, causing it to drive the two No. 2 rotating rods 335 to rotate. This controls the clamping plate 336 to drive the anti-sliding block 337 to clamp the fiberglass thread. At the same time, the outer wall of the other end of the No. 2 rotating rod 335 drives the scissor blade 338 to cut the fiberglass thread and separate it.
[0036] The movable structure 2 includes mounting brackets 21 bolted to both sides of the top of the operating platform 11. A second drive motor 24 is bolted to the outer wall of the bottom of the operating platform 11. A second threaded rod 23 is connected to the top of the second drive motor 24. A limit frame 22 is threaded to the outer wall of the second threaded rod 23. A first drive motor 222 is bolted to the outer wall of the inner side of the limit frame 22. A first threaded rod 221 is connected to the inner side of the first drive motor 222. A threaded moving block 223 is threaded to the outer wall of the first threaded rod 221. A connecting bracket 224 is bolted to the outer wall of one side of the threaded moving block 223.
[0037] It should be noted that in this embodiment, the second drive motor 24 drives the second threaded rod 23 to rotate. When the second threaded rod 23 rotates, its outer wall thread connects with the inner side of the limiting frame 22, causing it to control the limiting frame 22 to move up and down. When the first drive motor 222 is started, one end of the drive motor drives the first threaded rod 221 to rotate, causing the outer wall of the first threaded rod 221 to rotate with the inner side of the threaded moving block 223, causing it to control the connecting frame 224 to move left and right, thus controlling the collecting structure 3 to move down. The fiberglass cable is lowered to one side of the clustering plate 42. Then, the connecting frame 224 is controlled to drive the shovel plate 32 to insert into the bottom between the two clustering columns 43. Then, the collecting structure 3 is controlled to rise, which will drive the fiberglass cable to rise and thus detach the collected fiberglass cable. Then, while the collecting structure 3 is holding the fiberglass cable body, it is driven to move the fiberglass cable body to the other side, thereby guiding the fiberglass cable through the clustering columns 43. The fiberglass cable body is then inserted into the inner side of the top of the clamping column 44. After the clamping of the fiberglass cable body is released, the fiberglass on the upper surface of the shovel plate 32 is manually collected and reset.
[0038] The working principle of this invention is as follows: Glass fibers produced inside the drawing machine 5 are stretched out and initially guided through clamping posts 44. Then, the fourth drive motor 41 is activated, driving the bundling disk 42 to rotate. The bundling disk 42 then drives the bundling posts 43, causing the glass fibers to wrap around the outer walls of the two bundling posts 43, thus collecting them. The moving structure 2 then moves the scraper plate 32, which removes the glass fibers from the outer walls of the bundling posts 43.
[0039] By starting the motor 441, one end of the motor 441 drives the rotating disk 442 to rotate, which in turn controls the rotating column 443 to move the sliding rod 444 up and down. Simultaneously, both ends of the sliding rod 444 are limited within the limiting groove 445, causing the limiting plate 446 to move up and down. As the limiting plate 446 moves up and down, the toothed block 4461 on the inner side of the top of the limiting plate 446 meshes with the synchronous gear 4471 on the outer wall of the third rotating rod 447, thus controlling the rotation direction of the third rotating rod 447. This raises the pressure plate 448, and the fiberglass thread is placed on the upper surface of the rubber bottom pressure block 449. Simultaneously, the motor 441 is started and rotated in the opposite direction, controlling the pressure plate 448 to press the top rubber pressure block 4481 against the fiberglass thread on the upper surface of the bottom rubber pressure block 449.
[0040] The second drive motor 24 drives the second threaded rod 23 to rotate. When the second threaded rod 23 rotates, its outer wall thread connects with the inner side of the limiting frame 22, causing the limiting frame 22 to move up and down. When the first drive motor 222 is started, one end of the drive motor drives the first threaded rod 221 to rotate, causing the outer wall of the first threaded rod 221 to rotate with the inner side of the threaded moving block 223, causing the connecting frame 224 to move left and right, thus controlling the collecting structure 3 to descend to the clustering disk 42. On one side, the connecting frame 224 drives the shovel plate 32 to insert into the bottom between the two bundle pillars 43. Then, the collecting structure 3 is raised to lift the fiberglass line, thereby detaching the collected fiberglass line. Then, with the collecting structure 3 clamping the fiberglass line, the fiberglass line is moved to the other side, guiding it through the bundle pillars 43. The fiberglass line is then inserted into the inner side of the top of the clamping pillar 44. After the clamping of the fiberglass line is released, the fiberglass on the upper surface of the shovel plate 32 is manually collected and reset.
[0041] By starting the No. 3 drive motor 312, the transmission rod 313 is driven to rotate, causing the outer wall of the No. 1 inclined gear 314 at its bottom to mesh with the outer wall of the No. 5 inclined gear 339, thereby controlling the rotation of the No. 1 rotating rod 331. When the No. 1 rotating rod 331 rotates, it drives the outer wall of the No. 2 inclined gear 332 to mesh with the outer wall of the No. 3 inclined gear 333. When the No. 3 inclined gear 333 meshes with the No. 2 inclined gear 332, the outer wall of the No. 3 inclined gear 333 meshes with the outer wall of the No. 4 inclined gear 334, causing the two No. 2 rotating rods 335 to rotate. This controls the clamping plate 336 to drive the anti-slip block 337 to clamp the fiberglass thread. At the same time, the outer wall of the other end of the No. 2 rotating rod 335 drives the scissor blade 338 to cut the fiberglass thread and separate it.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
