Description

Technical Field

[0001] The utility model relates to the technical field of gluing production, in particular to a metering roller glue scraping device for a high-speed gluing machine. Background Art

[0002] In the process of manufacturing copper clad laminates, prepreg is one of its important raw materials, wherein the prepreg is formed by vacuum lamination of one or more layers of thermosetting resin (epoxy resin, hydrocarbon resin, polyphenylene ether resin, etc.) containing glass fiber cloth (base cloth).

[0003] Before vacuum lamination, glue coating is required, that is, the glue formed by thermosetting resin is coated on the glass fiber cloth. During the glue coating process, the excess glue on the glass fiber cloth needs to be squeezed out by two rotating metering rollers. It should be noted that in a low-speed coating machine, which usually runs at a speed of 2-20 meters per minute, the metering roller runs at a relatively low speed in the opposite direction of the glass fiber cloth. As the speed increases, the metering roller should generally drop to zero and then start to run in the same direction as the glass fiber cloth.

[0004] After extrusion, the residual glue on the metering roller generally needs to be scraped off with a scraper. However, in the prior art, there are many existing designs of scrapers based on low-speed gluing machines and in the opposite direction of the fiberglass cloth. The glue can be removed by gravity. However, there are fewer designs of scrapers for high-speed gluing machines and in the same direction as the fiberglass cloth, and it is more difficult to remove the glue. For example, when scraping the glue off the metering roller surface, if the blade and the metering roller surface are not well fitted, the glue is difficult to scrape clean and streaks will remain (similar to the streaks produced when the wiper is not wiped clean); if the fitting pressure between the blade and the metering roller surface is too large, the roller surface will be worn. Utility Model Content

[0039] The working process and principle of the metering roller glue scraping device for the high-speed glue applicator of the utility model are described in detail below.

[0040] First, pull the fixed column 501 through the pull ring 505 and overcome the elastic force of the fixed spring 502, so that the inner end of the fixed column 501 is completely retracted into the mounting hole 405, adjust the adjustment plate 402 to a suitable position, and make the adjustment hole 403 coaxial with the mounting hole 405, loosen the pull ring 505, and use the elastic force of the fixed spring 502 to push the fixed column 501 through the moving block 503 until the fixed column 501 is inserted into the adjustment hole 403, and use the corresponding cooperation between the fixed column 501 and the adjustment hole 403 to adjust the position of the adjustment plate 402 in the adjustment box 401, so that the scraper 3 can fit the roller surface of the metering roller body 7.

[0041] During actual use, the compression spring 103 uses its own elastic force to push the moving bar 102 outward, and uses the spring plate 105 to push the mounting bar 2, so that the scraper 3 on the mounting bar 2 can always fit the roller surface of the metering roller body 7, and the elasticity of the compression spring 103 is used to automatically adjust the pressure of the scraper 3 to always fit the roller surface of the metering roller body 7, so as to avoid the scraper 3 from failing to scrape off the glue or scratching the roller surface.

[0042] Finally, the external tube 603 is connected to an external vacuum pump, and the vacuum pump is used to exhaust air on the surface of the scraper 3 through the glue suction head 602 to suck the glue on the surface of the scraper 3 into the glue storage box 601. The glue is filtered through the filter net 605 and remains in the glue storage box 601 to prevent the glue from entering the vacuum pump, so that the glue scraped off by the scraper 3 will not drip onto other parts.
