[0029] The “front”, “front side”, “rear” or “rear side” mentioned in the present application is determined by the running direction of the fiber line 17 from the dry glass fiber to the membrane element 13.
[0030] like Figures 1 to 3 As shown, an embodiment of the present application provides a scraper mechanism of a glass fiber dipping machine, comprising two mounting plates 1 arranged opposite to each other, at least two scraper shafts 2 are detachably provided between the two mounting plates 1, all of the scraper shafts 2 are staggeredly arranged on both sides of the fiber line 17 along the forward direction of the fiber line 17, the scraper shafts 2 are perpendicular to the fiber line 17, a scraper piece is fixedly provided on the scraper shaft 2, the scraper piece is provided with edges, and the edges of the scraper piece are used for scraping glue.
[0031] The scraper mechanism of the glass fiber dipping machine provided in this embodiment has a scraper shaft 2 that is detachably fixed on the mounting plate 1, and the angle of the scraper shaft 2 is adjustable. The scraper shaft 2 is rotated to adjust the contact position between the edge of the scraper and the glass fiber line 17. The scraper is fixed after the scraper is in a suitable position, thereby adjusting the tension and the angle of the glass fiber, so that the tension on the fiber line 17 is uniform and of appropriate size, and while scraping off the glue attached to the surface of the glass fiber line 17, the surface of the fiber line 17 can be kept smooth without damaging the fiber, and the scraping effect is good, which is beneficial to improving the quality of the membrane element 13 product.
[0032] Preferably, the cross section of the scraper is fan-shaped or triangular. Specifically, the scraper is integrally formed with the scraper shaft 2, and the edges of the scraper surface are in contact with the fiber line 17 to scrape off excess glue on the fiber line 17. The angle of the scraper can be adjusted by rotating the scraper shaft 2. The adjustment process is simple and convenient, and the fiber line 17 is at a suitable tension and angle, and the scraper effect can be adjusted. After the scraper is adjusted to a suitable position, the scraper shaft 2 is fixed to the mounting plate 1 by screws.
[0033] like Figures 4 to 6 As shown, the present embodiment also provides a glass fiber dipping device, including the above-mentioned scraping mechanism, and also includes a glue box 3, two mounting plates 1 are relatively arranged on both sides of the glue box 3, and the scraping shaft 2 is located at the upper part of the glue box 3, and at least one guide mechanism 4 is arranged at the lower part of the mounting plate 1, and the guide mechanism 4 is located inside the glue box 3, and is used to guide the fiber line 17 into the glue box 3.
[0034] The glue dipping device is used in conjunction with an unwinding mechanism and a rewinding mechanism. An appropriate amount of AB glue is placed in the glue box 3. The dry glass fiber roll is mounted on the unwinding mechanism and unwound by the unwinding mechanism. The unwound fiber line 17 is guided and tensioned by the guide mechanism 4 and dipped into the glue in the glue box 3. Then it passes around the scraping parts on the scraping shaft 2. The edges of the staggered scraping parts contact the fiber line 17 respectively, so that the fiber line 17 is evenly tensioned and the excess glue on the fiber line 17 is scraped off. The glue content on the fiber line 17 after scraping is uniform, and then it is wound in an orderly manner on the membrane element 13 supported by the rewinding mechanism. The rotating membrane element 13 is driven to rotate by the driving mechanism, such as Figure 5 and Figure 6 In the direction indicated by the middle arrow, the fiber line 17 is wound around the membrane element 13. In this embodiment, in order to better and evenly support the tensioned fiber line 17, five guide mechanisms 4 are sequentially arranged along the advancing direction of the fiber line 17. The middle three guide mechanisms 4 are located in the glue box 3, so that the fiber line 17 can be fully immersed in the glue. The other two guide mechanisms 4 are respectively arranged at the positions before and after the fiber line 17 is immersed in the glue, so as to better support the tensioned fiber line 17 and balance its force.
[0035] In this embodiment, the guide mechanism 4 preferably includes a guide shaft and a guide sleeve sleeved on the guide shaft, the guide shaft is perpendicular to the fiber line 17, and the guide sleeve can rotate relative to the guide shaft. The fiber line 17 is wound around the guide sleeve of the guide mechanism 4. During the process of the fiber line 17 moving forward, the guide sleeve can rotate relative to the guide shaft, which can reduce the friction between the fiber line 17 and the guide sleeve, reduce the resistance of the fiber line 17, and prevent the fiber line 17 from fluffing. The guide sleeve is preferably a stainless steel tube, and the guide shaft is also made of stainless steel, so that the guide mechanism 4 can clean the residual glue in a corrosive cleaning agent, making the cleaning more convenient and thorough.
[0036] In this embodiment, preferably, a line-dividing roller 5 is provided on the mounting plate 1, and the line-dividing roller 5 is located on the upper side of the scraping shaft 2. The surface of the line-dividing roller 5 is provided with at least one line-dividing groove, and the line-dividing roller 5 is used to evenly divide the fiber lines 17 into the line-dividing groove. Specifically, the number of line-dividing grooves on the line-dividing roller 5 may be greater than or equal to the number of groups of fiber lines 17, and each group of fiber lines 17 is evenly divided in a line-dividing groove on the line-dividing roller 5, so that each group of fiber lines 17 can be arranged in an orderly manner, ensuring that the fiber lines 17 soaked in glue will not be bonded together, so that the thickness of the membrane element 13 product winding is more uniform.
[0037] This embodiment optimizes the above technical solution. Figure 5 and Figure 6 As shown, at least two groups of line-dividing rollers 5 are arranged above and below, and each group includes at least one line-dividing roller 5. Specifically, along the advancing direction of the fiber line 17, line-dividing rollers 5 are arranged on both the front and rear sides of the guide mechanism 4. After the fiber line 17 is divided by the line-dividing roller 5 on the front side, it bypasses multiple guide mechanisms in sequence, immerses in glue, and then passes through the scraper and line-dividing rollers 5 on the rear side in sequence, so that the fiber line 17 is evenly wound on the membrane element 13 on the rear side. At least two groups of line-dividing rollers 5 are arranged above and below the rear side of the scraper shaft 2, and each group of line-dividing rollers 5 is provided with at least one line-dividing roller 5. The fiber line 17 can bypass one group of line-dividing rollers 5 and be wound on the membrane element 13, so as to adapt to membrane elements 13 of different sizes. In order to better support the tensioning fiber line, a guide light roller 15 can be arranged on the mounting plate, and the guide light rollers 15 are distributed along the fiber line 17.

[0039] Specifically, the glue box 3 is detachably fixed on the bottom plate 6 for easy disassembly and cleaning. Two mounting plates 1 are arranged on opposite sides of the glue box 3, and the two mounting plates 1 are respectively fixed to the corresponding side plates from above the glue box 3, so that the mounting plates 1 are installed in the glue box 3, and the two ends of the scraper shaft 2, the guide shaft, the second guide shaft and the line dividing roller 5 are respectively installed on the mounting plates 1 on both sides.
[0040] In order to fix the mounting plate 1 on the side plate, in this embodiment, an open groove 9 is provided on the side plate, and the mounting plate 1 can be removably clamped on the open groove 9 by the cooperation of bolts and nuts 16.

The mounting plate 1 can be quickly installed on the bracket or removed from the bracket. The mounting plate 1, the scraper shaft 2 and the scraper parts thereon, and the line dividing roller 5 are all made of metal materials, which are corrosion-resistant. The mounting plate 1 and the structure thereon are placed in the DMF solution as a whole to remove the residual glue, thereby reducing the work intensity of the maintenance personnel in cleaning the residual glue.
[0041] In this embodiment, in order to further scrape off the excess glue on the membrane element 13, a cylinder 10 is provided on the side panel, and a scraper blade 12 is provided on the cylinder 10.
