Description

Technical Field

[0001] This utility model belongs to the technical field of drying equipment, and specifically relates to a glass fiber impregnation and drying device. Background Technology

[0002] Glass fiber impregnation and drying equipment is a key piece of equipment used in the production of glass fiber reinforced composites. Its core function is to uniformly impregnate glass fiber bundles with resin solution, followed by drying and pre-curing to form a continuous prepreg semi-finished product. In the glass fiber production process, the initial state of glass fibers is usually a tightly bundled structure. After being drawn from molten glass, hundreds to thousands of monofilaments are bonded together into a fiber bundle by a binding agent. Undispersed glass fiber bundles typically consist of hundreds to thousands of tightly arranged monofilaments with small internal gaps and dense arrangement, making it difficult for the resin to fully penetrate. Therefore, existing glass fiber impregnation processes may lead to the formation of bubbles and gaps, thus reducing the impregnation quality. Therefore, a new structure is proposed to solve these problems. Utility Model Content

The take-up roller has the same specifications as the unwinding roller, and the rear side of the take-up roller is driven by a motor.

[0029] An extrusion roller assembly for scraping off excess resin is installed inside the transfer port 202.

[0032] The first split roller 210 is installed at the center of the lower inner side of the soaking tank 200. The bottom of the first split roller 210 does not contact the lower inner surface of the soaking tank 200. The first split roller 210, the second split roller 220, and the third split roller 230 are parallel to each other.

[0033] The adjustment assembly 400 also includes an electric push rod 410 and a push rod. The electric push rod 410 is located at the top of the soaking tank 200. The output end of the electric push rod 410 is connected to the push rod, and the bottom of the push rod is fixed to the support plate 430.

[0034] A reinforcing plate is provided at the front and rear positions of the connection between the push rod and the support plate 430, and a triangular stable structure is formed between the reinforcing plate, the push rod and the support plate 430.

[0035] Four sets of guide posts 420 are provided at the four corners of the top of the support plate 430. Each set of guide posts 420 is provided with a limit block at the top. An adjusting roller 440 is installed on the left and right sides below the support plate 430. The two sets of adjusting rollers 440 are located on the left and right sides of the split roller 210.

[0036] Example 1: Please refer to Figures 1 to 3 In actual use, the coating box 100 is located at the top center of the workbench. An unwinding roller is installed on the right side of the coating box 100 for holding the glass fibers to be soaked, and a winding roller is installed on the left side for winding the soaked and dried glass fiber bundles. An soaking tank 200 is located on the right side inside the coating box 100, filled with resin for soaking. A drying chamber 300 is located on the left side of the soaking tank 200, with a discharge port 301 on the left side. A discharge guide roller 310 is installed on the outside of the discharge port 301. The drying chamber 300 contains a heating module and a hot air guide plate, and is equipped with a guide roller for the glass fibers. The guide roller assembly of the drying box 300 is existing technology, and its internal structure and working principle will not be described in detail here. The drying box 300 and the soaking tank 200 are separated by a heat insulation plate. A transfer port 202 is provided on the side of the heat insulation plate. A splitting roller 3 230 is installed on the right side of the transfer port 202. A feed port 201 is provided on the right side of the soaking tank 200. A splitting roller 220 is installed on the outside of the feed port 201. A splitting roller 1 210 is installed in the center of the lower part of the inner side of the soaking tank 200. The structures of splitting roller 1 210, splitting roller 220 and splitting roller 3 230 are the same and are all parallel to the take-up roller and the unwinding roller. A number of splitting grooves are opened from front to back on the curved surface of splitting roller 220.

[0037] In actual use, the glass fibers first pass through the splitting roller 220 from the outside of the unwinding roller to the left. They are then split by several splitting grooves on the surface of the splitting roller 220, thus separating the agglomerated glass fibers into several glass fiber bundles. The number of glass fiber bundles is the same as the number of splitting grooves. These glass fiber bundles enter the soaking tank 200 through the feed inlet 201 on the left side of the splitting roller 220. Then, the glass fiber bundles pass under the splitting roller 210, and are positioned inside the several splitting grooves on the outside of the splitting roller 210. The glass fiber bundles that pass over the splitting roller 210 continue to pass to the left. Below the third splitting roller 230 on the right side of the transfer port 202, the glass fiber bundles enter the drying chamber 300 through the transfer port 202. It should be noted that several strands of glass fiber will stay in the soaking tank 200 for 15 to 30 seconds for thorough soaking. The movement of the glass fiber bundles is driven by the rotation of the take-up roller. Compared with direct soaking, the glass fiber is split into several strands by the second splitting roller 220, the first splitting roller 210 and the third splitting roller 230, which greatly increases the soaking surface area of ​​the glass fiber, thereby reducing the generation of air bubbles and gaps on the glass fiber surface due to insufficient soaking and improving the soaking quality.

[0038] Example 2: Please refer to Figure 1 and Figure 4 When several glass fiber bundles are immersed in the immersion tank 200, the contact area between the fiber bundles and the resin is limited because a triangular structure is formed between the splitting rollers 220, 210, and 230. This contact area can be increased by the adjusting assembly 400, which includes a support plate 430, a guide column 420, and an adjusting roller 440. A push rod connects the top center of the support plate 430 to the bottom output end of an electric push rod 410 at the top of the immersion tank 200. The push rod connects to the top of the support plate 430 at the front and rear ends. A reinforcing plate is provided at each position, forming a triangular stable structure with the reinforcing plate, the support plate 430, and the push rod. This increases the connection stability between the push rod and the top of the support plate 430 and makes the downward thrust of the push rod more evenly distributed on the upper surface of the support plate 430. A guide post 420 is provided at each of the four corners of the top of the support plate 430. The four sets of guide posts 420 pass upward through the top of the soaking tank 200, and the top of the guide post 420 is provided with a limiting block. An adjusting roller 440 is installed on the left and right sides below the support plate 430. The specifications of the adjusting roller 440 are the same as those of the split roller 220.

[0039] In actual use, the electric push rod 410 can be activated (the electric push rod 410 is existing technology, and its internal structure and working principle will not be described in detail here). The electric push rod 410 pushes the support plate 430 downward inside the soaking tank 200 through the push rod. During the movement, the four sets of guide columns 420 can make the downward movement of the support plate 430 more stable, and can make the several bundled grooves on the surface of the adjusting roller 440 accurately dock with several strands of glass fiber when it moves downward. The support plate 430 drives the two sets of adjusting rollers 440 to move downward, and makes the several bundled grooves on the surface of the two sets of adjusting rollers 440 dock with several strands of glass fiber respectively. Therefore, through the two sets of The adjusting roller 440 presses down several strands of glass fiber, so that several strands of glass fiber on both sides of the splitting roller 210 are immersed in the resin inside the soaking tank 200. It should be noted that when the two sets of adjusting rollers 440 move downward, the horizontal height of their bottom will not be lower than the horizontal height of the bottom of the splitting roller 210. This is because the limiting block at the top of the guide column 420 can limit the guide column 420, thereby limiting the support plate 430, and then limiting the two sets of adjusting rollers 440. Therefore, the final effect is that by setting the adjusting component 400, the immersion surface area of ​​several strands of glass fiber can be significantly increased, thereby greatly increasing the immersion efficiency and improving the immersion quality.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
