[0002] The automatic fiberglass yarn hanging device is an automated equipment designed specifically for the fiberglass production industry. It aims to improve production efficiency, reduce labor intensity, and promote the automation upgrade of the fiberglass production line.

[0003] At present, the main method of hanging the yarn in glass fiber yarn production is to manually remove the yarn bundle from the roller and then guide it to the running machine head, resulting in low yarn hanging efficiency and safety risks in operation. Now, the yarn bundle is guided to the machine head by an automatic yarn hanging device with double rollers, thereby realizing automatic yarn hanging.

[0019] Before hanging the yarn, the waste yarn is flowed into the waste yarn barrel in the basement through the waste yarn guide plate 7, and then pushed forward by the yarn guide plate 3. After the yarn bundle is pushed to the position of the second roller 61 through the yarn guide round rod 4, the basic foundation for automatically hanging the yarn bundle can be completed.

[0023] The movement of the buffer spring 114 inside the second roller 61 can drive the slide bar 113 to slide on the fixed rod 11, which can effectively absorb the vibration and impact generated when the second roller 61 rotates, thereby stabilizing the tension of the yarn during the twisting process. At the same time, the elastic characteristics of the buffer spring 114 enable the two rollers to apply a more uniform and stable tension when twisting the yarn. This uniform tension helps the yarn to form a tighter and more uniform structure during the twisting process, thereby improving the twisting effect.

[0024] Embodiment 4 On the basis of the third embodiment, the outer wall of the main shaft 95 is fixedly connected with the mounting ring 10, the outer wall of one side of the mounting ring 10 is fixedly connected with the tooth claw 101, the outer wall of the tooth claw 101 is meshingly connected with the half gear 102, the axis positions of the two half gears 102 are fixedly connected with the connecting rod 103, the outer wall of one end of the connecting rod 103 is rotatably connected with the support plate 2, the outer wall of the bottom of the support plate is fixedly connected with the lower part of the interior of the protective outer cover 2, the lower part of the interior of the protective outer cover 2 is fixedly connected with the support plate 104, a through hole is opened on the support plate 104, the interior of the through hole is rotatably connected with the outer wall of the connecting rod 103, the interior of the protective outer cover 2 is fixedly connected with the support plate 3, the interior of the support plate 3 is rotatably connected with the yarn bundle pushing rod 8, the shape of the yarn bundle pushing rod 8 is L-shaped, and the yarn bundle pushing The outer wall of the rod 8 is fixedly connected to a fixed plate 107, and the outer wall of one side of the fixed plate 107 is fixedly connected to an electric push rod 108, and the output end of the electric push rod 108 is fixedly connected to a limiting block 106, and the interior of the limiting block 106 is slidably connected to the outer wall of the yarn bundle pushing rod 8, and a sliding groove 109 is provided on the side of the outer wall of the yarn bundle pushing rod 8 close to the fixed plate 107, and the interior of the limiting block 106 is fixedly connected to a square rod 1010, and the outer wall of the square rod 1010 is slidably connected to the outer wall of the sliding groove 109, and the outer wall of one side of the limiting block 106 is movably inserted into the limiting shell 105, and the outer wall of one side of the limiting shell 105 is fixedly connected to the outer wall of the other end of the connecting rod 103, and the outer wall of one side of the limiting shell 105 is provided with a square groove, and the outer wall of one end of the yarn bundle pushing rod 8 is movably inserted into the inside of the square groove.

[0025] Through the movement of the yarn bundle pushing rod 8, the driving rod at one end of the yarn bundle pushing rod 8 can make the yarn bundle stick to the edge of the machine head 5, and then the yarn bundle is wound up through the rapid rotation of the machine head 5, thereby completing the automatic yarn hanging process, avoiding the risk of yarn hanging failure when employees manually hang the yarn, causing waste yarn to fly around and causing employees to get pierced by waste yarn. The corresponding automatic yarn hanging reduces the chance of human operation and reduces the failure of yarn hanging due to human negligence or error. By realizing automatic yarn hanging, the production equipment can work continuously and stably, without being limited by the speed and accuracy of manual operation, thereby improving the production speed of the yarn bundle.

[0026] In actual use, first, before hanging the yarn, the waste yarn is flowed into the waste yarn barrel in the basement through the waste yarn guide plate 7, and then pushed forward by the yarn guide plate 3. After the yarn bundle is pushed to the position of the second roller 61 through the yarn guide round rod 4, the motor 9 can be started to rotate, and then the movement of the motor 9 will drive the conical wheel 91 to rotate, and then the rotation of the conical wheel 91 can simultaneously drive the driven wheel 92 and the driving wheel 93 to move, and then the movement of the driven wheel 92 and the driving wheel 93 can make the roller 1 6 and the roller 2 61 rotate accordingly, and the yarn can be twisted by the rotation of the two rollers, thereby reducing the need for manual intervention, improving production efficiency and automation level, and then reducing the downtime caused by yarn quality problems through the automated twisting and conveying process. When the yarn quality is stable and uniform, the failure rate in the weaving process is reduced, thereby improving the overall production efficiency.

[0027] It should be noted that the helix angles of the driving wheel 93 and the driven wheel 92 are opposite. When the driving wheel 93 rotates clockwise along with the conical wheel 91 , the driven wheel 92 rotates counterclockwise accordingly.

[0028] When roller 2 61 moves, through the cooperation of the fixed rod 11, the sliding rod 113 and the buffer spring 114 inside roller 2 61, when roller 2 61 is subjected to force during work, the internal buffer spring 114 can be squeezed, so that the buffer spring 114 is deformed under pressure, and then through the movement of the buffer spring 114, the sliding rod 113 can be driven to slide on the fixed rod 11, which can effectively absorb the vibration and impact generated when roller 2 61 rotates, thereby stabilizing the tension of the yarn during the twisting process. At the same time, the elastic characteristics of the buffer spring 114 enable the two rollers to apply more uniform and stable tension when twisting the yarn. This uniform tension helps the yarn to form a tighter and more uniform structure during the twisting process, thereby improving the twisting effect.

[0029] It should be noted that the internal structures of roller 1 6 and roller 2 61 are the same.

[0030] When the yarn twisting is completed, the machine is started, and then the work of the machine can drive the silk reel to start running. At this time, the electric push rod 108 is started, and then the movement of the electric push rod 108 can push the limit block 106 into the inside of the limit shell 105. Because one side of the limit block 106 and the inside of the limit shell 105 are both square, when the limit block 106 is inserted into the inside of the limit shell 105, it can move with the movement of the limit shell 105, thereby driving the yarn bundle pushing rod 8 to move.

[0031] At this time, the rotation of the main shaft 95 can drive the installation ring 10 to rotate, and then the movement of the installation ring 10 can make the tooth claw 101 move accordingly. When the tooth claw 101 moves to the position of the half gear 102, the meshing connection between the half gear 102 and the tooth claw 101 can make the half gear 102 rotate accordingly, and then the rotation of the half gear 102 can make the connecting rod 103 drive the limit shell 105 to move, and then the rotation of the limit shell 105 can make the square rod 1010 on the limit block 106 drive the yarn bundle pushing rod 8 to rotate on the support plate 3, and then the yarn bundle is pushed through The movement of the pushing rod 8 can make the driving rod at one end of the yarn bundle pushing rod 8 stick the yarn bundle to the edge of the machine head 5, and then the yarn bundle is wound up by the rapid rotation of the machine head 5, thereby completing the automatic yarn hanging process, avoiding the risk of yarn hanging failure when employees manually hang the yarn, causing waste yarn to fly around and causing employees to get pierced by waste yarn. The corresponding automatic yarn hanging reduces the chance of human operation and reduces the failure of yarn hanging due to human negligence or error. By realizing automatic yarn hanging, the production equipment can work continuously and stably, without being limited by the speed and accuracy of manual operation, thereby improving the production speed of the yarn bundle.

[0032] It should be noted that: when the toothed claw 101 passes through the first half gear 102, the connecting rod 103 can drive the yarn bundle pushing rod 8 to rotate upward; when the toothed claw 101 passes through the second half gear 102, the connecting rod 103 can drive the yarn bundle pushing rod 8 to return to its original position; the reciprocating motion of the yarn bundle pushing rod 8 can be realized through the cooperation of the toothed claw 101 and the half gear 102, so that the yarn bundle pushing rod 8 can return to its original position after completing pushing the yarn bundle.

[0033] Furthermore, the limit block 106 is in active contact with the limit shell 105. When the yarn bundle pushing rod 8 does not need to move, the limit block 106 can be driven by the electric push rod 108 to move back on the yarn bundle pushing rod 8, thereby releasing the connection between the limit block 106 and the limit shell 105, so that the yarn bundle pushing rod 8 can remain stationary, and the working state of the yarn bundle pushing rod 8 can be flexibly adjusted according to work requirements.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
