Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass fiber production technology, specifically to a long glass fiber feeding device that prevents fiber breakage. Background Technology
[0002] The anti-breakage long glass fiber feeding device is a specialized device for feeding long glass fibers. Its core function is to ensure that the long glass fibers do not break during the feeding process, while achieving stable and precise feeding. The anti-breakage long glass fiber feeding device is usually composed of a feeding mechanism, an anti-breakage mechanism, and a control system. In use, the long glass fibers are first stored in a specific container or roll and then enter the feeding mechanism through an appropriate guide device. The feeding mechanism conveys the long glass fibers to the processing equipment. When excessive tension of the long glass fibers is detected, the anti-breakage mechanism may automatically adjust the feeding speed or increase lubrication to reduce friction.
[0003] For example, Chinese patent CN222312307U, entitled "A Fiber-Preventing Fiber-Length Feeding Device," includes a bracket and a mounting frame. A telescopic plate is fixedly installed on the side wall of the mounting frame, and a ratchet is rotatably installed inside the mounting frame. A plug-in block is fixedly installed on the side wall of the ratchet. A rotating mechanism, including a handle, is fixedly installed at the end of the ratchet away from the plug-in block. A rotating roller is slidably installed on the side wall of the plug-in block. A wedge-shaped block is inserted into the top of the ratchet. A T-shaped rod is rotatably installed on the top of the wedge-shaped block. A disc is fixedly installed on the side wall of the T-shaped rod, and a spring is fixedly installed on the top of the disc. A mounting bracket is fixedly installed on the top of the mounting frame.
[0004] While the existing technologies can feed long glass fibers, in practical use, the fiber breakage prevention effect is not good enough. The tension of the fiber is usually adjusted manually, which can lead to fiber breakage after the tensioning drum rotates excessively. On the other hand, the take-up drum is not convenient to replace. Usually, the take-up drum needs to be removed from the support when replacing it, which requires disassembling and assembling multiple fixing mechanisms, thus reducing the efficiency of take-up replacement. Therefore, it does not meet the current needs. In response, we propose a fiber-breakage-preventing long glass fiber feeding device. Utility Model Content
[0005] The purpose of this invention is to provide a fiber-length feeder that prevents fiber breakage, in order to solve the problems mentioned in the background art, such as insufficient fiber breakage prevention and inconvenient replacement of the winding drum.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a fiberglass feeding device for preventing fiber breakage, comprising an operating table, a frame fixedly mounted at the lower end of the operating table, and fixed posts fixedly mounted at the front and rear ends of the upper center position of the operating table. A sliding groove is provided inside the fixed post, and a lead screw is provided inside the sliding groove. The upper and lower ends of the lead screw are rotatably connected to the inner wall of the sliding groove, respectively. A movable seat is sleeved on the outside of the lead screw, and the movable seat slides and limits the sliding of the sliding groove. One end of the movable seat extends to the outside of the sliding groove. An L-shaped fixing plate is fixedly mounted on the outside of one end of the movable seat. A third fixing frame is provided above the L-shaped fixing plate, and a tensioning cylinder is provided between the third fixing frames. The front and rear ends of the tensioning cylinder are rotatably connected to the third fixing frame. A servo motor is fixedly mounted at the upper end of the fixed post.
[0007] Preferably, mounting seats are fixedly provided on both sides of the L-shaped fixing plate. A hydraulic telescopic device is fixedly provided at one end of the mounting seat near the outside of the operating table. The telescopic end of the hydraulic telescopic device extends to the other end of the mounting seat. A limit ring is fixedly provided at one end of the telescopic end of the hydraulic telescopic device. The limit ring is sleeved on the outside of the tensioning cylinder, and the limit ring slides with the tensioning cylinder.
[0008] Preferably, the operating platform has two positioning cavities inside the fixed pile side, and the positioning cavities are symmetrically arranged. The operating platform has a fixing groove inside the lower end of the positioning cavity. The fixing groove is a through structure. The positioning cavity has a first fixing frame inside, and the upper end of the first fixing frame extends to the outside of the positioning cavity. A winding drum is arranged between the first fixing frames, and the front and rear ends of the winding drum are rotatably connected to the first fixing frame.
[0009] Preferably, a bolt is fixedly provided at the lower end of the first fixing frame, the lower end of the bolt extends to the bottom of the operating table through a fixing groove, and a nut is sleeved on the outside of the lower end of the bolt.
[0010] Preferably, a pressure sensor is fixedly installed at the lower end of the third fixing frame, and the lower end of the pressure sensor is fixedly connected to the L-shaped fixing plate.
[0011] Preferably, the operating platform is fixedly provided with two second fixing frames at the upper end on the other side of the fixing pile. The second fixing frames are symmetrically distributed, and a fixing cylinder is provided between the second fixing frames. The front and rear ends of the fixing cylinder are rotatably connected to the second fixing frames.
[0012] Preferably, control panels are fixedly installed at both the front and rear ends of the operating platform, and the control panels are electrically connected to the hydraulic telescopic device, servo motor, and pressure sensor.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) This utility model can adjust the position of the tensioning cylinder through the lead screw and the L-shaped fixing plate. When feeding fibers, if the pressure data exceeds the appropriate range, the operator can turn on the servo motor through the control panel, so that the output shaft of the servo motor drives the lead screw to rotate. The rotation of the lead screw drives the moving seat to move up and down inside the slide groove. At the same time, the L-shaped fixing plate fixedly connected to the moving seat moves together. At this time, the third fixing frame set on the L-shaped fixing plate moves up and down with the tensioning cylinder until the tensioning cylinder is moved to the appropriate position. At this time, the data monitored by the pressure sensor returns to the appropriate range, avoiding fiber breakage during feeding, thereby improving the efficiency of fiber production.
[0015] (2) This utility model can quickly position and install the take-up drum through bolts and positioning cavity. When installing a new take-up drum after feeding a roll of fiber, first align the lower end of the first fixing frame with the opening of the positioning cavity and push it into the positioning cavity so that the lower end of the first fixing frame contacts the inner wall of the positioning cavity. At the same time, the bolt at the lower end of the first fixing frame extends to the lower part of the operating table through the fixing groove. Then, the operator adjusts the position of the take-up drum in the Y-axis direction until the take-up drum is moved to correspond to the position of the tensioning drum. At this time, the operator puts the nut on the outside of the bolt and rotates it so that the nut moves upward outside the bolt until the nut contacts the lower end of the operating table, thus completing the fixing of the take-up drum and improving the flexibility of take-up drum replacement.
[0016] (3) This utility model is equipped with a pressure sensor to monitor the tension of the fiber. When feeding the fiber, the fiber is placed between the tensioning cylinder and the fixed cylinder and adjusted to a suitable position. The lower end of the fiber is in contact with the upper end of the tensioning cylinder and the upper end of the fiber is in contact with the lower end of the fixed cylinder. The limit ring is adjusted to a suitable position by the hydraulic telescopic device. At this time, the operator records the pressure data on the control panel. When feeding the fiber, the operator observes the pressure data on the control panel in real time. If the data exceeds the suitable range, the operator adjusts the tension of the fiber until the pressure data returns to the suitable range, thereby improving the accuracy of fiber tension observation.

[0024] Please see Figure 1 , Figure 2 and Figure 3 The fixed pile 10 has a sliding groove 11 inside, and a lead screw 12 inside the sliding groove 11. The upper and lower ends of the lead screw 12 are rotatably connected to the inner wall of the sliding groove 11, respectively. A movable seat 13 is sleeved on the outside of the lead screw 12. The movable seat 13 slides and limits the sliding of the sliding groove 11, and one end of the movable seat 13 extends to the outside of the sliding groove 11. An L-shaped fixing plate 14 is fixedly installed on the outside of one end of the movable seat 13. A third fixing frame 15 is installed above the L-shaped fixing plate 14. A tensioning cylinder 16 is installed between the third fixing frames 15. The front and rear ends of the tensioning cylinder 16 are connected to the third fixing frame 15. The fixed frame 15 is rotatably connected, and a servo motor 20 is fixedly installed at the upper end of the fixed pile 10. Mounting seats 18 are fixedly installed on both sides of the L-shaped fixed plate 14. A hydraulic telescopic device 19 is fixedly installed at one end of the mounting seat 18 near the outside of the operating table 1. The telescopic end of the hydraulic telescopic device 19 extends to the other end of the mounting seat 18. A limit ring 17 is fixedly installed at one end of the telescopic end of the hydraulic telescopic device 19. The limit ring 17 is sleeved on the outside of the tensioning cylinder 16, and the limit ring 17 slides with the tensioning cylinder 16, so as to facilitate the adjustment of the fiber tension through the tensioning cylinder 16.
[0025] Please see Figure 1 and Figure 4 The operating platform 1 has two positioning cavities 4 inside one side of the fixed pile 10. The positioning cavities 4 are symmetrically arranged. The operating platform 1 has a fixing groove 5 inside the lower end of the positioning cavity 4. The fixing groove 5 is a through structure. The positioning cavity 4 has a first fixing frame 6 inside. The upper end of the first fixing frame 6 extends to the outside of the positioning cavity 4.

[0027] Working principle: During use, the fiber is placed between the tensioning cylinder 16 and the fixed cylinder 9 and adjusted to a suitable position, with the lower end of the fiber contacting the upper end of the tensioning cylinder 16 and the upper end of the fiber contacting the lower end of the fixed cylinder 9. The limiting ring 17 is adjusted to a suitable position through the hydraulic telescopic device 19. At this time, the operator records the pressure data on the control panel 3. When feeding the fiber, the operator observes the pressure data on the control panel 3 in real time. If the data exceeds the appropriate range, the operator activates the servo motor 20 through the control panel 3, causing the output shaft of the servo motor 20 to drive the lead screw 12 to rotate. The rotation of the lead screw 12 drives the moving seat 13 to move up and down inside the slide groove 11. At the same time, the L-shaped fixing plate 14, which is fixedly connected to the moving seat 13, moves together. The third fixing bracket 15 on the fixing plate 14 moves up and down with the tensioning cylinder 16 until the tensioning cylinder 16 is moved to the appropriate position. At this time, the data monitored by the pressure sensor 21 returns to the appropriate range. When installing a new take-up drum 7, first align the lower end of the first fixing bracket 6 with the opening of the positioning cavity 4 and push it into the positioning cavity 4 so that the lower end of the first fixing bracket 6 contacts the inner wall of the positioning cavity 4. At the same time, the bolt 22 at the lower end of the first fixing bracket 6 extends to the lower part of the operating table 1 through the fixing groove 5. Then, the operator adjusts the position of the take-up drum 7 in the Y-axis direction until the take-up drum 7 is moved to correspond to the position of the tensioning cylinder 16. At this time, the operator puts the nut 23 on the outside of the bolt 22 and rotates it so that the nut 23 moves upward outside the bolt 22 until the nut 23 contacts the lower end of the operating table 1.
