Abstract
Description
Technical Field
[0001] This utility model belongs to the field of glass fiber production technology, and specifically relates to a glass fiber impregnation device. Background Technology
[0002] Glass fiber is a high-performance inorganic non-metallic material with many varieties. Its advantages include good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength. It is made from seven minerals—pyrophyllite, quartz sand, limestone, dolomite, borosilicate, and boromagnesia—through high-temperature melting, drawing, winding, and weaving processes. To enhance the performance of glass fiber, it is often coated or impregnated with a modifying solution during production.
[0003] When glass fibers are immersed, they need to be air-dried, which results in low work efficiency. Furthermore, the immersion liquid on the glass fibers is prone to dripping after they are removed, and residue is easily generated when the glass fibers pass through the immersion tank, leading to pollution and waste of the immersion liquid. Utility Model Content
[0004] The purpose of this invention is to provide a glass fiber impregnation device with a simple structure that can rapidly cool the impregnation liquid on the surface of the glass fiber, prevent the impregnation liquid from dripping out, and filter out glass fiber residue in the impregnation liquid, thus preventing waste of the impregnation liquid. It is highly practical and suitable for widespread application.
[0005] This utility model provides the following technical solution: a glass fiber impregnation device, including an impregnation tank, on which two symmetrically arranged downward pressure rollers are provided through an upward-opening slot, the downward pressure rollers are penetrated by a shaft, and retaining rings are fixed at both ends of the shaft, and a connecting arm is fixed between the two retaining rings on the same side, and a limiting seat is provided on the side wall of the impregnation tank above the connecting arm;
[0006] The immersion tank has an upward-sloping chute on one side, and a support frame is fixedly installed at the top of the chute. A drive roller is installed at the top of the support frame, and blower bars are installed on both sides of the support frame below the drive roller via rotating arms.
[0007] The immersion tank is located below the lower pressure roller and has a filter tank. The side wall of the filter tank is in contact with the tank wall of the immersion tank, and the bottom of the immersion tank is a filter screen that is in contact with the bottom of the immersion tank.
[0008] Preferably, a drive motor is provided on one side of the drive roller, a friction surface is provided on the side wall of the drive roller, and a guide roller is mounted on the side of the immersion tank away from the drive roller.
[0009] Preferably, the rotating arm is rotatably connected to the support frame via a rotating shaft, and the two sides of the blower strip are rotatably connected to the rotating arm via rotating shafts. One side of the blower strip is connected to an air supply pipe, which supplies hot air to the blower strip. The blower strip is provided with a strip-shaped air outlet, which is angled downward and directed towards the passing glass fiber.
[0010] Preferably, a stop block is slidably provided inside the limiting seat, and a support spring is fixedly provided inside the limiting seat for the stop block. The upper end of the part of the stop block extending out of the limiting seat is an inclined pressing surface, and the plane of the lower end of the stop block is in contact with the connecting arm.
[0011] The beneficial effects of this utility model are: simple structure, rapid cooling of the impregnation liquid on the surface of glass fiber, prevention of impregnation liquid dripping, and filtration of glass fiber residue in the impregnation liquid, preventing waste of impregnation liquid. It is highly practical, as detailed below:
[0012] (1) This utility model is equipped with an immersion tank. When the glass fiber passes through the immersion tank, it is pressed under the lower pressure roller and immersed in the immersion liquid in the immersion tank. After immersion, the glass fiber disc passes around the upper drive roller and is extracted by the rotation of the drive roller. There are blower strips on both sides of the glass fiber below the drive roller. They spray hot air onto the glass fiber after the immersion liquid is extracted, and the immersion liquid on the surface is dried quickly. After the glass fiber section is dried, the glass fiber under the two lower pressure rollers is immersed and can be dried. This speeds up the work. The immersion liquid falling from the surface of the extracted glass fiber will be caught by the inclined groove to prevent waste.
[0013] (2) This utility model is equipped with a filter tank, which is attached to the bottom of the immersion tank. When the immersion tank is removed, the filter screen below it will filter out the glass fiber residue. When the filter screen needs to be removed, press the stop block to make it retract into the limiting seat, and then lift the connecting arm to remove the lower pressure roller. At this time, the filter tank can be lifted upward. When installing it, press the filter tank to the bottom of the immersion tank, align the retaining ring of the guide roller with the retaining groove and press it down. When the rotating arm moves to the stop block, squeeze the inclined pressing surface to make the stop block retract into the limiting seat. After the rotating arm passes, the stop block blocks the rotating arm, so that the guide roller is fixed in position, which is convenient for disassembling and assembling the filter tank. The filter tank filters out the impurities in the immersion liquid, so that it maintains its purity and does not need to be replaced frequently. Attached Figure Description

[0022] The structural features of this utility model will now be described in detail with reference to the accompanying drawings.
[0023] See Figure 1-3A glass fiber impregnation device includes an impregnation tank 1. Two symmetrically arranged downward pressure rollers 3 are provided on the impregnation tank 1 through upward-opening slots 2. The downward pressure rollers 3 are penetrated by a shaft, allowing them to rotate freely. The downward pressure rollers 3 press down on the glass fiber 15 below, immersing it in the liquid. Clamping rings 4 are fixed at both ends of the shaft. A connecting arm 5 is fixed between the two clamping rings 4 on the same side. A limiting seat 6 is provided on the side wall of the impregnation tank 1 above the connecting arm 5. A stop block 17 is slidably arranged within the limiting seat 6. A support spring 18 is fixedly arranged within the limiting seat 6. The upper end of the stop block 17 extending out of the limiting seat 6 is a sloping pressure surface 19. The plane of the lower end of the stop block 17 is in contact with the connecting arm 5. When the rotating arm 11 moves to the stop block 17, it squeezes the sloping pressure surface 19, causing the stop block 17 to retract into the limiting seat 6. After the rotating arm 11 passes, the stop block 17 blocks the rotating arm 11, fixing the position of the guide roller 7.
[0024] See Figure 1-2 The immersion tank 1 has an upward-sloping trough 8 on one side to catch the dripping immersion liquid. A support frame 9 is fixed at the top of the trough 8, and a drive roller 10 is installed at the top of the support frame 9. A drive motor is installed on one side of the drive roller 10, and a friction surface is provided on the side wall of the drive roller 10. The drive roller 10 pulls the glass fiber 15. A guide roller 7 is installed on the side of the immersion tank 1 away from the drive roller 10. The glass fiber 15 rolls in from above the guide roller 7. The support frame 9 is located below the drive roller 10. Blower bars 12 are installed on both sides of the support frame 9 through rotating arms 11. The rotating arms 11 are rotatably connected to the support frame 9 through a rotating shaft. The two sides of the blower bars 12 are rotatably connected to the rotating arms 11 through rotating shafts. An air supply pipe is connected to one side of the blower bars 12, which supplies hot air to the blower bars 12. The blower bars 12 have strip-shaped air nozzles 16 that are angled downward and directed towards the passing glass fiber 15. The hot air from the blower bars 12 quickly dries the immersion liquid on the surface of the glass fiber 15.
[0025] The glass fiber impregnation device of this invention has a simple structure, can quickly cool the impregnation liquid on the surface of the glass fiber and prevent the impregnation liquid from dripping out, and can filter out glass fiber residue in the impregnation liquid to prevent waste of the impregnation liquid. It is highly practical and suitable for widespread application.
[0026] For specific usage, please refer to... Figure 1-2 When the glass fiber 15 passes through the immersion tank 1, it is pressed under the lower pressure roller 3 and immersed in the immersion liquid in the immersion tank 1. After immersion, the glass fiber 15 is coiled around the upper drive roller 10. The glass fiber 15 is extracted by the rotation of the drive roller 10. There are blower strips 12 on both sides of the glass fiber 15 below the drive roller 10. They spray hot air onto the glass fiber 15 that has been extracted from the immersion liquid to quickly dry the immersion liquid on the surface. After the glass fiber 15 is dried, the glass fiber 15 located under the two lower pressure rollers 3 is immersed and can be dried.
[0027] Reference Figure 1-3 The filter tank 13 is attached to the bottom of the immersion tank 1. When the immersion tank 1 is removed, the filter screen 14 below it filters out the residue that falls from the glass fiber 15. When the filter screen 14 needs to be removed, the connecting arm 5 can be lifted and the lower pressure roller 3 can be removed by pressing the stop block 17 to retract it into the limiting seat 6. At this time, the filter tank 13 can be lifted upward. When installing it, press the filter tank 13 to the bottom of the immersion tank 1, align the retaining ring 4 of the guide roller 7 with the retaining groove 2 and press it down. When the rotating arm 11 moves to the stop block 17, the inclined pressing surface 19 is squeezed to retract the stop block 17 into the limiting seat 6. After the rotating arm 11 passes, the stop block 17 blocks the rotating arm 11, fixing the position of the guide roller 7, thus completing the disassembly and assembly of the filter tank 13.
