On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0030] Embodiment 1:

[0031] Reference Figure 1 and Figure 3 The present embodiment provides a glass fiber sizing device, including a slurry pool 1, at least one sizing roller 3, at least one homogenizing roller 4 and at least one scraping part 5. The slurry pool 1 is used to hold slurry. The sizing roller 3 is located upstream of the homogenizing roller 4, and the sizing roller 3 can be raised and lowered in the vertical direction to enter and exit the slurry. The homogenizing roller 4 is suspended above the liquid surface of the slurry pool 1, and the scraping part 5 is arranged adjacent to the homogenizing roller 4, and the scraping part 5 maintains a preset distance from the homogenizing roller 4 to allow the glass fiber to pass between the two and to scrape off part of the slurry on the glass fiber, so that the sizing of the glass fiber 8 after sizing is uniform; the preset distance can be adjusted according to the sizing thickness requirements of the glass fiber 8, and the device is highly flexible in use.

[0032] Here, when only one homogenizing roller 4 is provided, one scraping part 5 cooperates with the homogenizing roller 4 to scrape. When multiple homogenizing rollers 4 are provided, multiple scraping parts 5 may be provided correspondingly, so that one homogenizing roller 4 is provided correspondingly to one scraping part 5; or a part of the homogenizing rollers 4 may be provided correspondingly to the scraping parts 5, which is not specifically limited here and is configured according to scraping requirements and space conditions.

[0033] A sizing roller 4 is arranged downstream of the sizing roller 3 to carry out a second winding of the sizing-applied glass fibers 8. The sizing roller 4 cooperates with the scraping part 5 to set a suitable preset distance, and the sizing-applied glass fibers 8 are uniformly scraped to finally obtain glass fibers with uniform sizing. At the same time, the scraping part 5 cooperates with the arc-shaped roller body in the sizing roller 4 to make the scraping process smoother, effectively avoid the occurrence of broken wires, improve the sizing quality of the glass fibers, and reduce cost losses.

[0034] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 , this embodiment provides a glass fiber sizing device, which also includes an upper frame 6, which is arranged above the pulp pool 1 to provide support. The scraping part 5 includes a pressing plate 51 and a support member 52. The upper end of the support member 52 is connected to the upper frame 6, and the lower end is hinged to the first end of the pressing plate 51. The second end of the pressing plate 51 points to the homogenizing roller 4 and maintains a preset distance therefrom. Specifically, the pressing plate 51 is located obliquely above the homogenizing roller 4, and the second end of the pressing plate 51 is provided with a notch 511. The notch 511 is adapted to the outer periphery of the homogenizing roller 4. At the same time, the notch 511 maintains a preset distance from the outer periphery of the homogenizing roller 4, so that the scraping is more uniform.

[0035] Further, refer to Figure 5 The second end of the pressing plate 51 is an elastic structure, such as silicone. The elastic material is softer, so that the glass fiber is not easy to break during the scraping process. At the same time, a non-stick layer 512, such as a Teflon coating, is provided on the side of the notch 511 facing the homogenizing roller 4. The non-stick property of Teflon can solve the problem of difficulty in cleaning after the sizing rubber solidifies.

[0036] Reference Figure 1 This embodiment provides a glass fiber sizing device, and the support member 52 includes a first rod body 521 and a second rod body 522 which are vertically arranged. The first rod body 521 is vertically arranged below the upper frame body 6, and the first rod body 521 plays a basic supporting role. One end of the second rod body 522 is hinged below the first rod body 521 and extends toward the homogenizing roller 4, and the other end is hinged to the pressing plate 51. Both ends of the second rod body 522 are connected in a hinged manner, which is convenient for adjusting the angle and preset distance of the pressing plate 51 relative to the homogenizing roller 4. When the pressing plate 51 is adjusted to the required position, both ends of the second rod body 522 can be fixed in the form of bolts to prevent the pressing plate 51 from moving. The cooperation of the first rod body 521 and the second rod body 522 improves the flexibility of the pressing plate 51 relative to the homogenizing roller 4, can adapt to different sizing thicknesses, and has a wider range of applications.

[0037] Reference Figure 1 and Figure 3This embodiment provides a glass fiber sizing device, which also includes two guide rollers 2, which are mounted at both ends of the pulp pool 1 in the upstream-to-downstream direction, and are used to control the moving direction of the glass fiber as a whole.

The axes of the guide roller 2, the sizing roller 3 and the homogenizing roller 4 are parallel to each other, which is conducive to the winding and movement of the glass fiber.

[0038] Reference Figure 1 and Figure 3 , this embodiment provides a glass fiber sizing device, which is provided with three sizing rollers 3 arranged from upstream to downstream and two homogenizing rollers 4 arranged from upstream to downstream; the three sizing rollers 3 make the glass fiber S-shaped winding, and the three sizing rollers 3 are slidably arranged on the side wall of the pulp pool 1 in the vertical direction. When the three sizing rollers 3 move down along the side wall of the pulp pool 1 and immerse in the slurry, the three sizing rollers 3 roll at the same time, and the sizing is uniform and free of bubbles; when sizing is not required or the machine is shut down for maintenance, the three sizing rollers 3 move out the slurry along the side wall of the pulp pool 1. The sizing rollers 3 move along the side wall of the pulp pool 1, which is more stable. Two homogenizing rollers 4 are provided, wherein the homogenizing roller 4 located upstream (left side) cooperates with the pressure plate 51 to scrape the slurry, and the homogenizing roller 4 located downstream (right side) plays the role of an intermediate support, and at the same time further strengthens the homogenizing effect of the glass fiber after scraping the slurry, and can change the movement direction of the glass fiber, and transfer the glass fiber to the downstream guide roller 2.

The opposing screws 34 are arranged on the upper frame body 6 along the axial direction of the sizing roller 3, and screw sleeves 35 are provided at both ends of the opposing screws 34. The upper ends of the two lifting rods 33 are hinged one-to-one to the bottom of the screw sleeves 35, and the two ends of the lifting frame 32 along the axial direction of the sizing roller 3 are hinged one-to-one to the lower ends of the two lifting rods 33. The two ends of the three sizing rollers 3 are connected to the lifting frame 32 at the same time. The three sizing rollers 3 can be located at the same height or have a height difference with each other. The adaptability of the lifting frame 32 can be improved as needed; the area on the side wall of the pulp pool 1 corresponding to the end of the middle sizing roller 3 is provided with a slide in the vertical direction. For specific reference Figure 2When the sizing roller 3 needs to be lifted, the opposing screw rod 34 rotates, and the screw sleeves 35 at both ends of the opposing screw rod 34 move in opposite directions, thereby pulling the two lifting rods 33 away from each other, and then the lifting rod 33 lifts the lifting frame 32. At this time, the two ends of the sizing roller 3 located in the middle move up along the slideway on the side wall of the pulp pool 1, and at the same time, the sizing rollers 3 located on both sides also move up under the drive of the lifting frame 32, thereby lifting the sizing roller 3. When the sizing roller 3 needs to be lowered, the opposing screw rod 34 rotates in the opposite direction, and the screw sleeves 35 move toward each other, thereby pulling the two lifting rods 33 close to each other, and then the lifting rod 33 lowers the lifting frame 32.
