Description

Technical Field

[0001] This utility model relates to the field of glass fiber drawing machine technology, and in particular to an auxiliary fiber feeding device for a glass fiber drawing machine. Background Technology

[0002] A glass fiber drawing machine is a mechanical device that draws molten glass into fiber filaments at high speed and winds them into fiber rolls according to a certain pattern.

[0003] Currently, there are many types of fiberglass drawing machines on the market. Traditional fiberglass drawing machines still rely on manual fiber drawing and loading, resulting in high labor intensity and low production efficiency. Some companies have begun to install traction and positioning mechanisms below the impeller mechanism. These mechanisms guide the fiber bundle into the traction groove via a horizontal swing arm, and then use active and passive rollers for traction to assist in automatic loading. However, in existing traction and positioning mechanisms, the compressed air and water pipes are exposed, making them susceptible to burns from high-temperature glass shards, affecting performance. Utility Model Content

[0004] To address the aforementioned problems, this invention provides an auxiliary fiber feeding device for a glass fiber drawing machine.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an auxiliary yarn feeding device for a glass fiber drawing machine, comprising a support sleeve that passes through the lower side of the side plate of the drawing machine frame, a connecting flange between the support sleeve and the side plate of the frame, a traction frame at the outer end of the support sleeve, a guide assembly, a yarn-laying assembly and a traction assembly on the traction frame, a drive shaft rotatably disposed inside the support sleeve, a drive motor for driving the drive shaft to rotate at the inner end of the support sleeve, a traction assembly connected to the outer end of the drive shaft, a protective sleeve covering the support sleeve, one end of the protective sleeve being connected to the connecting flange and the other end being connected to the traction frame, a cavity being formed between the protective sleeve and the support sleeve, and through holes communicating with the cavity on the connecting flange and the traction frame, the cavity being used for the passage of an air supply pipe and a water pipe.

[0006] By adopting the above technical solution, a protective sleeve is installed on the support sleeve to form a clamping cavity, and through holes on the connecting flange and the traction frame communicate with the clamping cavity. In this way, the air pipe and water pipe can be passed into the clamping cavity through the through hole of the connecting flange and out through the through hole of the traction frame, thereby guiding the air pipe and water pipe onto the traction frame. Under the protection of the protective sleeve, the high temperature glass shards can be prevented from burning the air pipe and water pipe, ensuring the normal operation of the air pipe and water pipe.

[0007] Furthermore, the guiding assembly includes a horizontal guide plate disposed on the traction frame, the guide plate being provided with an arc-shaped guide groove, and a U-shaped open guide plate being disposed on the guide plate at the inner end of the arc-shaped guide groove.

[0008] By adopting the above technical solution, a guide plate, an arc-shaped guide groove, and an open guide plate are set to guide the filament bundle, which facilitates the filament bundle traction and positioning.

[0009] Furthermore, the yarn arranging assembly includes a fixing plate disposed on the guide plate, the fixing plate being provided with a horizontal yarn arranging unit and a vertical yarn arranging unit, and the fixing plate being provided with a waterproof cover covering the horizontal yarn arranging unit and the vertical yarn arranging unit.

[0010] By adopting the above technical solution, a horizontal yarn-laying unit and a vertical yarn-laying unit are set on the fixed plate to guide the yarn bundle in the horizontal and vertical directions, respectively; and a waterproof cover is set to protect the horizontal yarn-laying unit and the vertical yarn-laying unit.

[0011] Furthermore, the horizontal yarn-swinging unit includes a first yarn-swinging shaft that is vertically rotatably mounted on a fixed plate. The lower end of the first yarn-swinging shaft passes through the fixed plate and the guide plate and is provided with a yarn-swinging plate. A first gear is provided on the shaft of the first yarn-swinging shaft located on the fixed plate. A first cylinder is horizontally arranged on the fixed plate. A first rack is provided at the end of the piston rod of the first cylinder. The first rack meshes with the first gear.

[0012] By adopting the above technical solution, a first yarn-swinging shaft, a yarn-swinging plate, a first gear, a first cylinder, and a first rack are set up. The first cylinder drives the first rack to move horizontally, which in turn drives the first gear to rotate, thereby driving the first yarn-swinging shaft and the yarn-swinging plate to rotate, thus causing the yarn bundle to swing in the horizontal direction.

[0013] Furthermore, the vertical yarn-swinging unit includes two support plates spaced apart on a fixed plate. A horizontally arranged second yarn-swinging shaft is rotatably arranged between the two support plates. One end of the second yarn-swinging shaft passes through the support plate and is provided with a yarn-swinging rod. A yarn-swinging hook is provided at the end of the yarn-swinging rod away from the second yarn-swinging shaft. A second gear is provided on the shaft of the second yarn-swinging shaft located between the two support plates. A second cylinder is horizontally arranged on the fixed plate. A second rack is provided at the end of the piston rod of the second cylinder. The second rack meshes with the second gear.

[0014] By adopting the above technical solution, a support plate, a second yarn-shaping shaft, a yarn-shaping rod, a yarn-shaping hook, a second gear, a second cylinder, and a second rack are set up. The second cylinder drives the second rack to move horizontally, which in turn drives the second gear to rotate, thereby driving the second yarn-shaping shaft to rotate. This causes the yarn-shaping rod to drive the yarn-shaping hook to move the yarn bundle in the vertical direction, thereby adjusting the angle of the yarn bundle at the opening guide plate and reducing the friction between the yarn bundle and the opening guide plate.

[0015] Furthermore, the traction assembly includes a mounting plate disposed at the end of the support sleeve. A drive roller is rotatably disposed on the mounting plate. The outer end of the drive shaft is connected to the drive roller shaft. A U-shaped seat is disposed on the side of the mounting plate. A swing seat is rotatably disposed inside the U-shaped seat via a swing shaft. A threaded rod is protruding from the side of the mounting plate below the U-shaped seat. A through hole is disposed on the swing seat corresponding to the threaded rod. A nut is threadedly connected to the rod body passing through the through hole. A compression spring is disposed on the rod body between the nut and the swing seat. The two ends of the compression spring abut against the nut and the swing seat respectively. A driven roller is rotatably disposed on the swing seat. The drive roller meshes with the driven roller, and the meshing point is located directly below the inner end of the arc-shaped guide groove.

[0016] By adopting the above technical solution, a driving roller and a driven roller are set up. The filament bundle is clamped between the driving roller and the driven roller through meshing, thereby realizing the traction of the filament bundle. A U-shaped seat, a swing seat, a threaded rod, a through hole, a nut, and a compression spring are set up. The degree of meshing between the driven roller and the driving roller can be adjusted by adjusting the position of the swing seat relative to the driving roller.

[0017] Furthermore, the guide plate is provided with a nozzle connected to the water pipe in the clamping cavity, and the spray direction of the nozzle is towards the open guide plate.

[0018] By adopting the above technical solution, a nozzle is installed on the guide plate, which can spray water onto the yarn at the opening of the guide plate, thereby achieving the purpose of cooling the yarn.

[0019] In summary, this utility model has the following beneficial effects: In this application, by providing a protective sleeve over the support sleeve to form a clamping cavity, and by having through holes on the connecting flange and the traction frame that communicate with the clamping cavity, the air pipe and water pipe can be inserted into the clamping cavity through the through hole of the connecting flange and out through the through hole of the traction frame, thereby guiding the air pipe and water pipe onto the traction frame. Under the protection of the protective sleeve, the high-temperature glass shards can be prevented from burning the air pipe and water pipe, ensuring the normal operation of the air pipe and water pipe.

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] like Figure 1-4 As shown in the illustration, this application discloses an auxiliary fiber feeding device for a glass fiber drawing machine, including a support sleeve 10, a traction frame 20, a guide assembly 30, a yarn-aligning assembly 40, and a traction assembly 50. The support sleeve 10 is disposed through the lower side of the side plate of the drawing machine frame, and a connecting flange 11 is provided between the support sleeve 10 and the side plate of the frame to fix the support sleeve 10. The traction frame 20 is disposed at the outer end of the support sleeve 10, and is used to mount the guide assembly 30, the yarn-aligning assembly 40, and the traction assembly 50. The guide assembly 30 is used to guide the fiber bundle, the yarn-aligning assembly 40 is used to drive the fiber bundle to move along the guide assembly 30, and the traction assembly 50 is used to pull and position the fiber bundle at the desired position, thereby assisting the fiber feeding on the drawing machine head.

[0026] The setup involves a protective sleeve 14 covering the support sleeve 10. One end of the protective sleeve 14 is connected to the connecting flange 11, and the other end is connected to the traction frame 20, thus forming a cavity 15 between the protective sleeve 14 and the support sleeve 10. The cavity 15 is used for the passage of air and water pipes. Through holes 60 communicating with the cavity 15 are provided on the connecting flange 11 and the traction frame 20. During installation, the air and water pipes are inserted into the cavity 15 through the through hole 56 of the connecting flange 11 and exit through the through hole 56 of the traction frame 20, thereby guiding the air and water pipes onto the traction frame 20 to provide air and water sources for the air-using and water-using components on the traction frame 20. By arranging the air and water pipes within the cavity 15 and protecting them with the protective sleeve 14, burns from high-temperature glass shards can be prevented, ensuring the normal operation of the air and water pipes.

[0027] Specifically, the guiding assembly 30 includes a horizontal guide plate 31 mounted on the traction frame 20. The guide plate 31 has an arc-shaped guide groove 32. One side of the arc-shaped guide groove 32 is mounted on the guide plate 31 body, and the other side has an arc-shaped guide rod. The distance between the end of the arc-shaped guide rod furthest from the guide plate 31 and the guide plate 31 gradually increases, thus making the arc-shaped guide groove 32 flared outwards and inwards, allowing the filament bundle to be better guided into the arc-shaped guide groove 32. A U-shaped open guide plate 33 is mounted on the guide plate 31 at the inner end of the arc-shaped guide groove 32. The inner opening of the open guide plate 33 is smoothly designed to reduce friction with the filament bundle, thereby reducing the risk of filament bundle breakage. A nozzle 34 is also provided on the guide plate 31. The spray direction of the nozzle 34 is towards the open guide plate 33. The lower end of the nozzle 34 is connected to the water pipe in the clamping cavity 15. That is, water is supplied to the nozzle 34 through the water pipe in the clamping cavity 15, so that water is sprayed onto the yarn at the open guide plate 33 through the nozzle 34, thereby achieving the purpose of cooling the yarn.

[0028] The yarn-laying assembly 40 includes a fixed plate 41 mounted on a guide plate 31. The fixed plate 41 is equipped with a horizontal yarn-laying unit 42 and a vertical yarn-laying unit 43, which guide the yarn bundle in the horizontal and vertical directions, respectively. A waterproof cover 44 is also mounted on the fixed plate 41, covering the horizontal yarn-laying unit 42 and the vertical yarn-laying unit 43 to protect them.

[0029] The horizontal yarn-swinging unit 42 includes a first yarn-swinging shaft 421 vertically rotatably mounted on a fixed plate 41. The lower end of the first yarn-swinging shaft 421 passes through the fixed plate 41 and the guide plate 31 and is fitted with a yarn-swinging plate 422. A first gear 423 is mounted on the shaft of the first yarn-swinging shaft 421 located on the fixed plate 41. A first cylinder 424 is horizontally arranged on the fixed plate 41. A first rack 425 is mounted on the piston rod end of the first cylinder 424, and the first rack 425 meshes with the first gear 423. The first cylinder 424 drives the first rack 425 to move horizontally, thereby rotating the first gear 423, which in turn drives the first yarn-swinging shaft 421 and the yarn-swinging plate 422 to rotate, thus oscillating the yarn bundle in the horizontal direction and guiding the yarn bundle along the arc-shaped guide groove 32 into the U-shaped opening of the open guide plate 33.

[0030] The vertical yarn-swinging unit 43 includes two support plates 431 spaced apart on the fixed plate 41. A horizontally arranged second yarn-swinging shaft 432 is rotatably arranged between the two support plates 431. One end of the second yarn-swinging shaft 432 passes through the support plate 431 and is provided with a yarn-swinging rod 433. A yarn-swinging hook 434 is provided at the end of the yarn-swinging rod 433 away from the second yarn-swinging shaft 432. A second gear 435 is provided on the shaft of the second yarn-swinging shaft 432 located between the two support plates 431. A second cylinder 436 is horizontally arranged on the fixed plate 41. A second rack 437 is provided at the end of the piston rod of the second cylinder 436. The second rack 437 meshes with the second gear 435. The second cylinder 436 drives the second rack 437 to move horizontally, which in turn drives the second gear 435 to rotate, thereby driving the second yarn shaft 432 to rotate. This causes the yarn rod 433 to drive the yarn hook 434 to move the yarn bundle in the vertical direction, thereby adjusting the angle of the yarn bundle at the opening guide plate 33 and reducing the friction between the yarn bundle and the opening guide plate 33.

[0031] The traction assembly 50 includes a drive roller 52 and a driven roller 59. The drive roller 52 and the driven roller 59 mesh with each other, and the meshing point is located directly below the inner end of the arc-shaped guide groove 32. When the filament is guided into the U-shaped opening of the open guide plate 33, the filament at the lower end of the open guide plate 33 is just located at the meshing point of the drive roller 52 and the driven roller 59. In this way, the filament can be wound around the drive roller 52 under the meshing rotation of the drive roller 52 and the driven roller 59, thereby achieving the traction and positioning of the filament. With the rotation of the drawing machine head, the filament can be fed.

[0032] Specifically, the traction assembly 50 includes a mounting plate 51 disposed at the end of the support sleeve 10, and a drive roller 52 rotatably disposed on the mounting plate 51. A drive shaft 12 is rotatably disposed inside the support sleeve 10, and a drive motor 13 for driving the drive shaft 12 is disposed at the inner end of the support sleeve 10. The outer end of the drive shaft 12 is connected to the axle of the drive roller 52 of the traction assembly 50, so that the drive motor 13 can drive the drive shaft 12 to drive the drive roller 52 to rotate.

[0033] A U-shaped seat 53 is provided on the side of the mounting plate 51. A swing seat 55 is rotatably provided inside the U-shaped seat 53 via a swing shaft 54. A threaded rod 511 is protruding from the side of the mounting plate 51 below the U-shaped seat 53. A through hole 56 is provided on the swing seat 55 corresponding to the threaded rod 511. A nut 57 is threadedly connected to the rod body of the threaded rod 511 passing through the through hole 56. A compression spring 58 is provided on the rod body of the threaded rod 511 located between the nut 57 and the swing seat 55. The two ends of the compression spring 58 abut against the nut 57 and the swing seat 55 respectively. A driven roller 59 is rotatably provided on the swing seat 55. With the arrangement of U-shaped seat 53, swing seat 55, threaded rod 511, through hole 56, nut 57 and compression spring 58, the position of nut 57 on threaded rod 511 can be adjusted by rotating nut 57, thereby driving swing seat 55 to rotate around swing shaft 54, so as to adjust the position of swing seat 55 relative to driving roller 52, thereby adjusting the meshing degree between driven roller 59 and driving roller 52.
