Description

A reciprocating large-roll heavy-duty fiber drawing machine for fiberglass heads Technical Field

[0001] This utility model relates to the field of glass fiber drawing machine technology, and in particular to a glass fiber drawing machine with a reciprocating large roll weight. 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, mainstream fiber drawing machines on the market primarily produce yarn by using a traversing and reciprocating mechanism combined with a rotating main shaft impeller mechanism. This results in small yarn roll weights, which is detrimental to yarn untying in subsequent processes. Furthermore, uneven yarn distribution and short winding times make the production cycle time at the drawing site, the automated logistics cycle time for yarn roll handling / transfer, and the cycle time of subsequent processes extremely tight. Precise coordination between each link is essential to ensure production efficiency. Therefore, increasing the roll weight and quality of yarn produced by fiberglass drawing machines is crucial for improving production efficiency. Summary of the Invention

[0004] To address the aforementioned problems, this utility model provides a reciprocating large-winding fiber drawing machine for glass fiber heads.

The rodless cylinder 44 drives the clamping block 45 to slide the fiber-blocking rod 43 within the linear bearing, thereby moving the fiber-blocking plate 47. This allows the glass fiber bundle to be pushed onto the winding ring 302 at the front end of the impeller for winding and fixing, and then the glass fiber bundle is released for winding, making the process convenient and efficient.

[0042] The reciprocating shift fork mechanism 50 includes a shift fork 51, an annular slide rail 52, and a reciprocating assembly 53. There are two shift forks 51, which are respectively fixedly sleeved on the rear ends of the main shaft sleeves 22 of the two main shaft mechanisms 20. Two anti-rotation guide rails 55 are symmetrically arranged on the flip shaft 12 with the same length direction as the guide rails. Guide sliders 56 are slidably arranged on the anti-rotation guide rails 55. The shift fork 51 and the corresponding guide slider 56 are connected by a guide seat 57, thereby guiding the shift fork 51 and preventing the shift fork 51 from rotating.

[0043] The annular slide rail 52 is fixedly installed inside the frame 1, and two notches 521 are opened on it corresponding to the positions of the two shift forks 51. The shift forks 51 are provided with U-shaped seats 54 and are slidably connected to the annular slide rail 52 through the U-shaped seats 54. The reciprocating assembly 53 includes a reciprocating bracket 532, a reciprocating plate 533, and a reciprocating connecting plate 531. The reciprocating bracket 532 is fixedly mounted on the top of the frame 1. The reciprocating plate 533 is horizontally arranged on the reciprocating bracket 532. A reciprocating lead screw 534, which is arranged along the length of the main shaft 23, is rotatably mounted on the reciprocating plate 533. A reciprocating driven pulley 5341 is provided at one end of the reciprocating lead screw 534. A reciprocating motor 535 is also mounted on the reciprocating plate 533. A reciprocating driving pulley 5351 is provided on the output shaft of the reciprocating motor 535. The reciprocating driving pulley 5351 and the reciprocating driven pulley 5341 are connected by a reciprocating synchronous belt 5352. The reciprocating motor 535 drives the reciprocating driving pulley 5351 to rotate, and the reciprocating synchronous belt 5352 drives the reciprocating driven pulley 5341 and the reciprocating lead screw 534 to rotate. A nut slide block 536 is helically connected to a reciprocating screw 534. Two reciprocating slide rails 537, arranged parallel to each other along the length of the main shaft 23, are arranged on the bottom surface of the reciprocating plate 533. A reciprocating slide block 538 is slidably mounted on the two reciprocating slide rails 537. A slotted hole 539 is formed at the beginning of the reciprocating plate 533. The reciprocating slide block 538 is fixedly connected to the nut slide block 536, and the connection point is located within the slotted hole 539. When the reciprocating screw 534 rotates, the nut slide block 536 moves, thereby driving the reciprocating slide block 538 to slide on the reciprocating slide rails 537. A reciprocating connecting plate 531 is mounted on the reciprocating slide block 538 and moves along the length of the main shaft 23 with the reciprocating slide block 538. The thickness of the reciprocating connecting plate 531 is the same as that of the annular slide rail 52, and it is initially located at the notch 521 on the upper side of the annular slide rail 52.

[0044] The auxiliary unloading mechanism 60 includes an unloading bracket 62 installed in the frame 1. An unloading slide rail 63 with the length direction of the main shaft 23 is installed on the unloading bracket 62. An unloading slide seat 64 is slidably installed on the unloading slide rail 63. An unloading screw 65 with the length direction of the main shaft 23 is rotatably installed on the unloading bracket 62. An unloading driven pulley 651 is installed at one end of the unloading screw 65. An unloading motor 66 is also installed on the unloading bracket 62. An unloading drive pulley 661 is installed on the output shaft of the unloading motor 66. The unloading drive pulley 661 and the unloading driven pulley 651 are connected by an unloading synchronous belt 662. A nut connecting seat 67 is screwed onto the unloading screw 65. The nut connecting seat 67 is fixedly connected to the unloading slide seat 64. An unloading connecting plate 61 is installed on the unloading slide seat 64. The unloading drum motor 66 drives the unloading drum drive pulley 661 to rotate, which in turn drives the unloading drum driven pulley 651 and the unloading drum screw 65 to rotate via the unloading drum synchronous belt 662. This drives the nut connecting seat 67 to move the unloading drum slide 64 along the unloading drum slide rail 63, causing the unloading drum connecting plate 61 to move along the length of the main shaft 23. The thickness of the unloading drum connecting plate 61 is the same as that of the annular slide rail 52, and it is initially located at the notch 521 on the lower side of the annular slide rail 52.

[0045] The reciprocating connecting plate 531 and the unloading connecting plate 61 are used to fill the two gaps 521 on the annular slide rail 52. In the working state, the reciprocating connecting plate 531 is locked in the U-shaped seat 54 of the upper shift fork 51, and the unloading connecting plate 61 is locked in the U-shaped seat 54 of the lower shift fork 51. Driven by the reciprocating motor 535 of the reciprocating assembly 53, the reciprocating connecting plate 531 drives the upper shift fork 51 to reciprocate, thereby driving the main shaft sleeve 22 of the upper working position to reciprocate, and then driving the corresponding impeller to reciprocate, realizing the reciprocating motion of the impeller in the working position for yarn drawing during the yarn drawing process. The unloading connecting plate 61 is driven by the unloading motor 66 to drive the lower shift fork 51 to move horizontally, thereby driving the main shaft sleeve 22 of the lower spare position to move horizontally, and then driving the corresponding impeller to move horizontally, which can push out the spare impeller for easy yarn unloading and pull back the spare impeller mechanism 30 after yarn unloading. After the impeller at the work station finishes pulling the yarn, the turntable 11 is driven to rotate by the flip motor 15, so that the main shaft 23 and the impeller in the working position and the standby position are swapped. At this time, the U-shaped seat 54 on the shift fork 51 slides on the annular slide rail 52, and the position is swapped synchronously with the main shaft 23 and the impeller.
