Description

Technical Field

[0001] This application relates to the field of oiling equipment technology, and in particular to an oiling equipment for uniformly applying a wetting agent. Background Technology

[0002] Glass fiber is a high-performance inorganic non-metallic material that is commonly used as a reinforcing material in composite materials, an electrical insulation material, a thermal insulation material, and a circuit board in various sectors of the national economy.

[0003] During the fiber drawing process, an oiler is used to coat the surface of the glass fiber with a sizing agent, which serves to lubricate, bond, and protect the glass fiber. Related technologies have proposed an oiler comprising an oil box and an oiling roller. The oiling roller is rotatably connected to the oil box, and its lower part is immersed in the sizing agent within the oil box. When a motor drives the oiling roller to rotate, the glass fiber passes through the oiling roller, thus achieving the oiling process for the glass fiber.

[0004] Regarding the aforementioned technologies, although the oiling roller can coat glass fibers, the method of coating one side can easily lead to uneven coating of the glass fibers with sizing agent. One side is too thick, which can cause the glass fibers to stick together; the other side is too thin or even has no sizing agent, which cannot play a protective role and causes abnormalities such as glass fiber flying, breaking, and fuzzing, affecting the production and quality of glass fibers. Utility Model Content

[0005] In order to improve the problem that unilateral oiling by oiling roller affects the yield and quality of glass fibers, this application provides an oiler for uniformly coating the wetting agent.

[0006] The oiling device for uniformly coating wetting agent provided in this application adopts the following technical solution:

[0007] An oiler for uniformly coating a wetting agent includes an oil box and a single-sided oiling mechanism symmetrically arranged on both sides of the oil box. The oil box is connected to an inlet pipe and an outlet pipe. The single-sided oiling mechanism includes a drive roller, a driven roller, a coating ring, and a first rotating motor. The first rotating motor is located on the oil box, and the drive roller is connected to the rotating shaft of the first rotating motor. The lower part of the drive roller is located inside the oil box. The driven roller is located on the oil box, and the coating ring is arranged around the drive roller and the driven roller. A gap is left between the two coating rings to allow glass fibers to pass through.

[0008] By adopting the above technical solution, this oiler uses symmetrically arranged single-sided oiling mechanisms on both sides of the oil box. The active roller, in conjunction with the first rotating motor, drives the coating ring to move, thereby ensuring that the sizing agent is evenly distributed on the surface of the coating ring. This ensures that both sides of the glass fiber can fully and evenly contact the sizing agent when passing through the gap of the coating ring, allowing both sides of the glass fiber to be uniformly coated with sizing agent. This improves the problem of single-sided oiling by the oiling roller affecting the output and quality of glass fiber. The driven roller ensures the stable operation of the coating ring and prevents glass fiber breakage from falling into the oil box, reducing the probability of broken glass fiber clogging the feed pipe and discharge pipe, thus ensuring the normal supply of sizing agent in the oil box.

[0009] Optionally, the oil box has an arc-shaped through groove corresponding to each driven roller, and a slider is slidably engaged in the arc-shaped through groove. Each driven roller is rotatably connected to the corresponding slider around its own axis. The oil box is provided with a drive mechanism for synchronously driving the two sliders to move closer or further apart.

[0010] By adopting the above technical solution, the arc-shaped through-slot and slider configuration enable the driven roller to move along the arc-shaped path, achieving adjustable position of the driven roller. This allows for adjustment of the spacing between the coating rings to accommodate glass fibers of different diameters. The introduction of the drive mechanism further ensures the synchronous movement of the two sliders, maintaining the symmetry of the coating rings on both sides, thereby improving the working stability and coating uniformity of the oiler.

[0011] Optionally, the driving mechanism includes a slide and two connecting rods. The slide is slidably connected to the oil box, and both connecting rods are rotatably connected to the slide. One connecting rod is rotatably connected to a slider, and the other connecting rod is rotatably connected to another slider. The oil box is provided with a moving component for driving the slide to move.

[0012] By adopting the above technical solution, the slide block slides along the oil box under the drive of the moving component, causing two connecting rods to rotate. One end of the connecting rod is rotatably connected to the slide block, and the other end is rotatably connected to the two sliders respectively, thereby realizing the synchronous movement of the two sliders towards or away from each other. This movement mode can synchronously and precisely adjust the distance between the two sliders, thereby adjusting the spacing between the coating rings so that the coating rings are tightly pressed against both sides of the glass fiber, ensuring that the glass fiber can be evenly coated with wetting agent when passing through the gap. At the same time, the smooth movement of the sliders helps to maintain the stability of the overall structure of the oiler and improves the reliability of the coating effect.

[0013] Optionally, the moving component includes a second rotating motor and a lead screw. The lead screw is rotatably connected to the oil box about the sliding direction of the slide block. The lead screw passes through the slide block and is threadedly connected to the slide block. The second rotating motor is located on the oil box, and the rotating shaft of the second rotating motor is connected to the lead screw.

[0014] By adopting the above technical solution, the second rotary motor drives the lead screw to rotate, and the threaded connection between the lead screw and the slide converts the rotational motion into the linear motion of the slide, thereby achieving precise control of the slide position; and by utilizing the self-locking characteristic of the threaded connection, the slide position can be relatively locked when the second rotary motor is not started, further improving the stability of the driven roller position adjustment.

[0015] Optionally, the slider has an insertion hole, a rotating cylinder is inserted into the insertion hole, and a compression spring is connected between the rotating cylinder and the inner wall of the insertion hole; the driven roller is rotatably connected to the rotating cylinder through a bearing.

[0016] By adopting the above technical solution, the driven roller can be made to float elastically, ensuring that the coating rings on the driving roller and the driven roller always maintain appropriate tension, further improving the contact uniformity between the coating rings and the glass fiber, thereby improving the wetting agent coating effect.

[0017] Optionally, a first rotating rod is rotatably connected to the oil box around a vertical axis, and the first rotating rod is provided with a spiral blade; the driving roller is provided with a driving bevel gear, and the first rotating rod is provided with a driven bevel gear, and the driving bevel gear meshes with the driven bevel gear.

[0018] By adopting the above technical solution, the meshing transmission structure between the first rotating rod and the active roller can effectively stir the wetting agent in the oil box. The spiral blades allow the wetting agent to flow vertically in the oil box, thereby preventing the wetting agent from stratifying due to static placement and ensuring uniform distribution of the wetting agent on the coating ring surface. The cooperation between the active bevel gear and the driven bevel gear further improves the stability of power transmission, ensuring the stirring effect without affecting the normal operation of the active roller.

[0019] Optionally, a second rotating rod is rotatably connected to the oil box in a vertical direction. Multiple second rotating rods are arranged axially around the first rotating rod. The second rotating rod is provided with stirring blades. The first rotating rod is provided with a driving gear, and the second rotating rod is provided with a driven gear. The driving gear and the driven gear mesh.

[0020] By adopting the above technical solution, the second rotating rod is equipped with stirring blades, which can stir the wetting agent in the oil box in multiple directions, avoiding the problem of layering or sedimentation of the wetting agent due to standing, and ensuring the uniformity of the concentration of the wetting agent in the entire oil box. The first rotating rod is connected to the driven gear on the second rotating rod through the meshing of the driving gear, forming a stable transmission structure. This allows the power of the first rotating rod to be effectively transmitted to multiple second rotating rods, thereby driving multiple stirring blades to work synchronously, improving the stirring efficiency and reducing the probability of blockage of the feed pipe and discharge pipe due to sedimentation of the wetting agent. The multiple second rotating rods are arranged axially around the first rotating rod, further enhancing the stirring coverage and uniformity, providing a high-quality wetting agent environment for subsequent glass fiber coating, and ensuring the stability of the coating effect.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The two sets of symmetrically arranged single-sided oiling mechanisms can uniformly coat both sides of the glass fiber with sizing agent, which improves the problem of single-sided oiling by oiling roller affecting the output and quality of glass fiber. The driven roller ensures the stable operation of the coating ring and prevents the glass fiber from falling into the oil box when it breaks, reducing the probability of broken glass fiber clogging the feed pipe and discharge pipe, thereby ensuring the normal supply of sizing agent in the oil box.

[0023] 2. The matching arrangement of the arc-shaped through groove, slider and drive mechanism realizes the adjustability of the driven roller position, thereby adjusting the spacing between the coating rings to accommodate glass fibers of different diameters and improve the applicability of the oiler of this application;

[0024] 3. The arrangement of the first rotating rod, spiral blades, driving bevel gear and driven bevel gear enables effective stirring of the wetting agent in the oil box, and the spiral blades allow the wetting agent to flow vertically in the oil box, thereby preventing the wetting agent from stratifying due to standing and ensuring uniform distribution of the wetting agent on the surface of the coated rubber ring.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] Example 1:

[0032] This application discloses an oiler for uniformly coating a wetting agent. (Refer to...) Figure 1-2 An oiler for uniformly applying wetting agent includes an oil box 1 and single-sided oiling mechanisms 2 symmetrically arranged on the left and right sides of the oil box 1. The oil box 1 has a wire-passing groove 11 in the middle, an inlet pipe 3 connected to the bottom left side of the oil box 1, and an outlet pipe 4 connected to the bottom right side of the oil box 1. The wetting agent enters the oil box 1 through the inlet pipe 3 and flows out of the oil box 1 through the outlet pipe 4, thus achieving the storage and circulation of the wetting agent.

[0033] The single-sided oiling mechanism 2 includes a drive roller 21, a driven roller 22, a coating ring 23, and a first rotating motor 24. The first rotating motor 24 is mounted on the oil box 1, and the drive roller 21 is connected to the rotating shaft of the first rotating motor 24. The lower part of the drive roller 21 is located in the wetting agent inside the oil box 1. The driven roller 22 is rotatably connected to the oil box 1 and is located above the threading groove 11. The coating ring 23 is wound around the drive roller 21 and the driven roller 22, and multiple coating rings 23 are spaced apart along the length of the drive roller 21. A gap is left between the two coating rings 23 in the two single-sided oiling mechanisms 2 to allow glass fibers to pass through. The coating ring 23 is usually made of flexible polymer material, which has good elasticity and adsorption capacity. The thickness of the coating ring 23 is generally 2mm to 5mm. The surface of the coating ring 23 can be increased with microporous structure to improve its adsorption capacity for the wetting agent.

[0034] The first rotating motor 24 within the two single-sided oiling mechanisms 2 rotates in opposite directions, thereby driving the coating ring 23 to absorb the sizing agent. When the glass fiber passes through the threading groove 11, the coating ring 23 contacts the glass fiber, and the sizing agent is evenly transferred to the surface of the glass fiber by the pressing action of the driven roller 22. The structure is relatively simple and easy to use, improving the problem of affecting the output and quality of glass fiber by using a single-sided oiling method with an oiling roller. Furthermore, since the driven roller 22 is located above the threading groove 11, if the glass fiber breaks during the drawing process, the broken glass fiber will fall through the threading groove 11 and will not fall into the oil box 1, reducing the risk of clogging the feed pipe 3 and the discharge pipe 4.

[0035] Furthermore, a first rotating rod 12 is vertically rotatably connected inside the oil box 1. The rotating rod is equipped with helical blades 121. A driving bevel gear 211 is coaxially connected to the driving roller 21, and a driven bevel gear 13 is coaxially connected to the first rotating rod 12. The driving bevel gear 211 and the driven bevel gear 13 mesh. When the driving roller 21 rotates, it drives the driving bevel gear 211 to rotate, which in turn drives the driven bevel gear 13 to rotate. This, in turn, drives the rotating rod and its helical blades 121 to rotate, allowing the wetting agent to circulate vertically while being stirred. This prevents the wetting agent from separating due to static conditions, ensuring uniform distribution of the wetting agent on the surface of the coating ring 23 and improving the coating effect.

[0036] In addition, a second rotating rod 14 is vertically rotatably connected inside the oil box 1. Multiple second rotating rods 14 are axially arranged around the first rotating rod 12, and each second rotating rod 14 is equipped with stirring blades 141. A drive gear 122 is coaxially connected to the first rotating rod 12, and driven gears 142 are coaxially connected to the second rotating rods 14. The drive gear 122 meshes with all the driven gears 142. While the first rotating rod 12 rotates, under the meshing transmission of the drive gear 122 and the driven gears 142, it synchronously drives all the second rotating rods 14 and their stirring blades 141 to rotate. This provides comprehensive and large-area stirring of the wetting agent in the oil box 1, enhancing the stirring coverage and uniformity, improving stirring efficiency, and reducing the probability of blockage in the feed pipe 3 and discharge pipe 4 due to sedimentation of the wetting agent. This provides a high-quality wetting agent environment for subsequent glass fiber coating, ensuring the stability of the coating effect.

[0037] The implementation principle of the oiler for uniformly coating the sizing agent in this embodiment is as follows: During use, the sizing agent enters the oil box 1 through the feed pipe 3 and flows out of the oil box 1 through the discharge pipe 4, realizing the storage and circulation of the sizing agent in the oil box 1; then, the glass fiber is passed through the threading groove 11 and through the gap between the coating rings 23 on the left and right sides, and the glass fiber is in close contact with the coating rings 23. The two first rotating motors 24 are started to rotate in opposite directions, thereby driving the coating rings 23 to rotate in a cycle. The sizing agent is uniformly transferred to the surface of the glass fiber by the pressing action of the driven roller 22, which improves the problem of affecting the output and quality of glass fiber by unilateral oiling by the oiling roller. While the drive roller 21 rotates, it drives the spiral blades 121 on the first rotating rod 12 to rotate through the meshing of the drive bevel gear 211 and the driven bevel gear 13. It also drives the stirring blades 141 on the second rotating rod 14 to rotate through the meshing of the drive gear 122 and the driven gear 142. This achieves large-scale uniform stirring of the wetting agent in the oil box 1, reduces the probability of blockage of the feed pipe 3 and the discharge pipe 4 due to the sedimentation of the wetting agent, and provides a high-quality wetting agent environment for the subsequent coating of glass fiber, ensuring the stability of the coating effect.

[0038] Example 2:

[0039] This application discloses an oiler for uniformly coating a wetting agent. The difference between Embodiment 2 and Embodiment 1 is that, referring to... Figure 3 The oil box 1 has arc-shaped slots 15 corresponding to each driven roller 22. The center of the arc-shaped slot 15 on the left is located on the axis of the driven roller 21 on the left, and the center of the arc-shaped slot 15 on the right is located on the axis of the driven roller 21 on the right. A slider 5 is slidably engaged in the arc-shaped slot 15. An insertion hole 51 is opened on the upper side of the slider 5, and a rotating cylinder 52 is inserted into the insertion hole 51. Multiple compression springs 53 are connected between the rotating cylinder 52 and the inner wall of the insertion hole 51. The arrangement of the compression springs 53 allows the rotating cylinder 52 to have a certain degree of positional adjustability. The driven roller 22 on the left is rotatably connected to the rotating cylinder 52 on the left via a bearing, and the driven roller 22 on the right is rotatably connected to the rotating cylinder 52 on the right via a bearing. The oil box 1 is provided with a drive mechanism for synchronously driving the two sliders 5 to move closer or further apart.

[0040] In use, the two sliders 5 are driven by the drive mechanism to slide along the corresponding arc-shaped through grooves 15, moving closer or further apart. This allows the distance between the two driven rollers 22 to be adjusted, thereby adjusting the minimum distance between the coating rings 23 on the left and right sides. This adapts to the sizing of glass fibers of different diameters, making it more versatile. Furthermore, the combination of the rotating drum 52 and the compression spring 53 ensures that the coating rings 23 are firmly pressed against the glass fibers, maintaining contact between the coating rings 23 and the glass fibers, further improving the stability and effectiveness of the glass fiber sizing.

[0041] For example, the driving mechanism includes a slide 6 and two connecting rods 7. The slide 6 is slidably connected to the side wall of the oil box 1 in a vertical direction. One end of each of the two connecting rods 7 is rotatably connected to the slide 6. The other end of the left connecting rod 7 is rotatably connected to the left slider 5, and the other end of the right connecting rod 7 is rotatably connected to the right slider 5. The oil box 1 is provided with a moving component for driving the slide 6 to rise and fall. The moving component drives the slide 6 to rise and fall, and under the action of the connecting rods 7, the two sliders 5 can be synchronously driven to move closer or further apart. The structure is simple and practical.

[0042] Specifically, the moving component includes a second rotary motor 8 and a lead screw 9. The lead screw 9 is rotatably connected to the oil box 1 about the sliding direction of the slide 6. The lead screw 9 passes through the slide 6 and is threadedly connected to the slide 6. The second rotary motor 8 is mounted on the oil box 1, and its rotating shaft is connected to the lead screw 9. When the second rotary motor 8 is started, it drives the lead screw 9 to rotate. Under the transmission action of the threaded connection between the lead screw 9 and the slide 6, the slide 6 moves along the length of the lead screw 9. The threaded transmission method makes the movement of the slide 6 stable and precise and can form a self-locking mechanism, improving the accuracy of the movement of the slide 6.

[0043] The implementation principle of the sizing agent applicator in this embodiment is as follows: When it is necessary to apply sizing agent to glass fibers of different diameters, the second rotating motor 8 can be directly started, driving the lead screw 9 to rotate, thereby causing the slide block 6 to move up and down. Under the action of the connecting rod 7, the two sliders 5 can move closer or further apart, thereby adjusting the distance between the two coating rings 23 to adapt to glass fibers of different diameters. Furthermore, with the rotating cylinder 52 and the compression spring 53, the coating rings 23 can be tightly pressed against the glass fibers, ensuring that the coating rings 23 and the glass fibers remain in contact, further improving the stability and effect of the glass fiber sizing agent coating.

[0044] The above are all optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
