Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber composite felt processing devices, in particular to a PTFE auxiliary impregnation device for making glass fiber composite felt. Background Art

[0002] Glass fiber composite felt is made of glass fiber untwisted roving arranged in unidirectional parallel, the outermost layer of composite short-cut glass fiber yarn or chopped short mat is sewn with organic fiber, and in order to improve the tensile properties of glass fiber composite felt, the composite felt is usually immersed in PTFE resin solution to make the internal structure of the composite felt more stable.

[0003] However, when using the existing PTFE-assisted impregnation device for making glass fiber composite felt, an ordinary conveyor roller is usually used to press the composite felt fabric downward into the PTFE resin solution. Since the liquid level of the solution will drop as the composite felt is impregnated and absorbed, and the height of the conveyor roller is fixed, the composite felt that subsequently enters the device cannot be completely immersed in the resin solution, resulting in a poor impregnation effect of the glass fiber composite felt. In addition, when the existing glass fiber composite felt slides out of the device after the impregnation is completed, the surface usually brings out the unabsorbed resin solution, and since the inside of the composite felt is soaked with the resin solution, the resin solution on the surface will flow to the edge of the composite felt and drip to the ground, causing unnecessary waste of the resin solution.

[0023] like Figures 1 to 4As shown, the PTFE auxiliary impregnation device for making glass fiber composite felt in this embodiment includes a bottom box 1, a vertical frame 2 is set at the top of the bottom box 1, two brackets 6 are set at the bottom of the vertical frame 2, an electric roller 8 is installed at the bottom of the bracket 6, a plurality of needles 9 are fixedly connected to the outer wall of the electric roller 8, vertical rods 3 are fixedly connected to both sides of the top of the bracket 6, the interior of the bottom box 1 is filled with a PTFE resin solution 15, a screen 17 is set at the bottom of the inner side of the bottom box 1, and thin ropes 16 are movably connected at the four corners of the screen 17, a feed port 13 is opened at the top of one side wall of the bottom box 1, and a discharge port 18 is opened on the other side wall of the bottom box 1, and an inclined plate 11 is clamped on one side wall of the discharge port 18, a smoothing roller 10 is rotatably connected to the junction of the inclined plate 11 and the discharge port 18, and two clamping rollers 12 are rotatably connected to the inner wall of the inclined plate 11 away from the discharge port 18.

[0024] Specifically, an inner cavity is provided at the top of the bottom box 1 for containing the PTFE resin solution 15, and at the same time, it is beneficial for the glass fiber composite felt entering the device to be immersed in the PTFE resin solution 15, thereby realizing the impregnation of the glass fiber composite felt. The function of the vertical frame 2 is to support the card frame 6, so that the height of the card frame 6 can be flexibly adjusted with the change of the liquid level height of the resin solution in the inner cavity. The electric roller 8 can rotate on the card frame 6 after being connected to the external power supply, so that the glass fiber felt entering the device can be pierced with fine holes by the needle 9, thereby facilitating the resin solution to penetrate into the interior of the glass fiber felt through the fine holes, accelerating the infiltration speed of the resin solution, and at the same time, it is beneficial to improve the impregnation effect of the glass fiber composite felt. The diameter of the needle 9 is small, and the fine holes pierced will not cause structural damage to the interior of the glass fiber composite felt. The function of the vertical rod 3 is to reinforce the card frame 6, so that the card frame 6 maintains better stability during the up and down movement. PTFE is a polymer. Tetrafluoroethylene is relatively stable in nature and is usually used as a surface coating. The mesh size of the screen 17 is 100 meshes, which can promptly pick up the granular impurities deposited at the bottom of the resin solution, so that the impurities in the resin solution are reduced, which is beneficial to the subsequent reuse of the resin solution to reduce unnecessary waste. The thin rope 16 is in a relaxed state when the bracket 6 is lower than the height of the top of the bottom box 1, and will not interfere with the downward movement of the cross plate 14 and the bracket 6. It will only be straightened when the horizontal height of the bracket 6 is higher than the bottom box 1, so that the screen 17 can be pulled out from the inside of the bottom box 1, so that the sediment in the resin solution can be cleaned out in time, which is beneficial to the reuse of the resin solution. The function of the inclined plate 11 is to drain the unsoaked resin solution squeezed out by the clamping roller 12 back to the inside of the bottom box 1, thereby avoiding the situation where the resin solution drips to the ground along the surface of the glass fiber composite felt, reducing unnecessary waste of the resin solution.

[0025] Furthermore, a spring 4 is provided on the top movable sleeve of the vertical rod 3, and a circular plate 5 is fixedly connected to the top of the vertical rod 3. The spring 4 can pull the vertical rod 3 through its own deformation, so that the vertical rod 3 can maintain stable sliding in the vertical direction, which is beneficial for the vertical rod 3 to maintain the stability of the bracket 6.

[0026] Furthermore, the bottom end of the spring 4 is fixedly connected to the vertical frame 2, the vertical rod 3 is movably connected to the vertical frame 2, and the bracket 6 is movably connected to the vertical frame 2 through the vertical rod 3 and the spring 4. When the bracket 6 slides up and down, the vertical rod 3 also slides up and down at the top of the vertical frame 2, thereby helping to maintain the stability of the bracket 6 when it slides up and down.

[0027] Furthermore, a transverse plate 14 is fixedly connected to the middle of the two brackets 6, and the top end of the thin rope 16 is fixedly connected to the bracket 6. The transverse plate 14 can increase the synchronization of the two brackets 6 when sliding up and down, so that both ends of the glass fiber composite felt entering the device can be immersed in the resin solution at the same time, thereby improving the impregnation effect of the glass fiber composite felt.

[0028] Furthermore, an electric push rod 7 is fixedly installed in the middle of the vertical frame 2, and the output end of the electric push rod 7 is engaged with the cross plate 14, and the screen 17 is movably embedded in the bottom box 1 through the cross plate 14. The electric push rod 7 can drive the cross plate 14 to move up and down, so that the brackets 6 at both ends of the cross plate 14 can drive the electric roller 8 to move up and down, thereby realizing flexible adjustment of the height of the electric roller 8, which is beneficial to keep the glass fiber composite felt immersed in the resin solution.

[0029] Furthermore, an opening is provided on one side wall of the inclined plate 11, and the opening is connected to the discharge port 18. The inclined plate 11 is connected to the interior of the bottom box 1 through the opening and the discharge port 18. The resin solution dripping on the inclined plate 11 can flow back to the bottom box 1 along the inclined surface of the inclined plate 11, thereby reducing the probability of the resin solution dripping onto the ground.

[0030] Furthermore, the screen 17 is located at the bottom of the PTFE resin solution 15, and the screen 17 is movably connected to the PTFE resin solution 15 through the thin rope 16. When the screen 17 is pulled upward by the thin rope 16, it will slide along the PTFE resin solution 15, pick up the sediment in the resin solution, and clean the resin solution, which is beneficial to the subsequent reuse of the resin solution.

[0031] The method of using this embodiment is as follows: when using the PTFE auxiliary impregnation device for making glass fiber composite felt, it is necessary to first connect the device to an external power supply, and then the glass fiber composite felt will enter the bottom box 1 from the feed port 13 under the action of the driving structure, and then start the electric push rod 7 to drive the cross plate 14 and the bracket 6 to move downward, so that the bracket 6 drives the electric roller 8 to move downward, so that the electric roller 8 presses the glass fiber composite felt into the PTFE resin solution 15 of the bottom box 1, and then start the electric roller 8 so that the electric roller 8 rolls along the surface of the glass fiber composite felt, driving the needle 9 to pierce fine holes on the surface of the glass fiber composite felt, so that the PTFE resin solution 15 quickly penetrates into the interior of the glass fiber composite felt through the fine holes, and when the liquid level of the resin solution becomes low, the electric push rod 7 can be controlled to continue to extend, so that the cross plate 14 and the bracket 6 continue to move downward. , so that the glass fiber composite felt is always immersed in the PTFE resin solution 15. After the glass fiber composite felt is completely immersed, it will slide out from the discharge port 18, and then move to the clamping roller 12 through the smoothing roller 10. At this time, the clamping roller 12 will roll the impregnated glass fiber composite felt, so that the PTFE resin solution 15 that is not absorbed on the surface of the glass fiber composite felt is squeezed out, and then flows to the inclined plate 11, and then flows back to the bottom box 1 along the inclined surface of the inclined plate 11. After use, the electric push rod 7 can be controlled to retract, so that the bracket 6 is lifted up, so that the thin rope 16 is straightened, and the screen 17 is driven to slide up along the inner cavity of the bottom box 1, so that the sediment in the PTFE resin solution 15 is picked up by the screen 17, and then the sediment on the screen 17 can be cleaned, so that the resin solution inside the bottom box 1 can be reused.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
