Description

Technical Field

[0001] The utility model belongs to the technical field of papermaking machinery and relates to a double-scraper film transfer sizing machine. Background Art

[0002] Due to the special processability of the raw materials, the oil filter paper and fuel filter paper are relatively loose and thick, and they are required to have a high dust holding capacity. The traditional dipping and extrusion gluing method will reduce the dust holding effect of the finished paper, and the glue coating is uneven, which is difficult to adjust during production; the current coating sizing machine simply applies resin glue on the filter paper. If air or paper hair is mixed in the resin glue, it will cause uneven glue thickness on the filter paper surface, resulting in white paper disease, which seriously affects the appearance and quality of the paper. In addition, when splicing the paper rolls, it is necessary to scrape off the excess resin glue on the glue roller. When splicing paper rolls, it is necessary to separate the glue rollers to avoid paper breakage during splicing. The existing utility model patent with patent number CN219824739U, the splicing scraper device of the four-roller film transfer coating machine includes a control system and an equipment frame, and the equipment frame is rotatably connected to two mutually cooperating glue rollers, and each glue roller is provided with a metering roller next to each other, and each metering roller is rotatably connected to the equipment frame, and the equipment frame is provided with a scraping glue bracket corresponding to the glue roller one by one, and each scraping glue bracket is provided with a scraping glue mechanism, and the scraping glue mechanism is connected to the control system.

[0003] The prior art has the following technical defects:

[0004] The above technical solution solves the problem of needing to stop the machine when splicing paper rolls. However, when the paper passes through the glue roller, impurities such as paper fibers will be left on the glue roller. When the paper rotates again to apply glue, the glue liquid will be impure, thus affecting the product quality caused by appearance defects or uneven glue thickness. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a double-scraper film transfer glue applicator.

[0006] The double-scraper film transfer glue applicator described in the utility model comprises an equipment frame, on which two glue coating rollers that cooperate with each other are rotatably connected, a metering roller is arranged beside each glue coating roller, and each metering roller is rotatably connected to the equipment frame, and an upper glue scraping bracket and a lower glue scraping bracket corresponding to the glue coating rollers are arranged on the equipment frame, an upper scraper is arranged on the upper glue scraping bracket, and a lower scraper is arranged on the lower glue scraping bracket, and both the upper scraper and the lower scraper are connected with an adjustment component.

[0007] Working process or working principle:

[0008] When in use, the paper is coated with glue through two glue rollers. After the paper passes through the glue rollers, the upper scraper is used to scrape off the residual glue and stained paper fibers on the glue rollers to avoid the paper fibers from covering the new paper surface when gluing again, thereby avoiding streaks on the paper and ensuring the workshop environment when downstream customers fold paper. At the same time, the lower scraper can be used to achieve splicing without separating the glue rollers when splicing paper rollers.

[0009] The adjustment component includes a rotating shaft and a cylinder bracket respectively arranged on the upper scraper bracket and the lower scraper bracket. The upper scraper and the lower scraper are respectively hinged to the corresponding rotating shafts. An adjustment cylinder is hinged on the cylinder bracket. The adjustment cylinder is hinged to the corresponding upper scraper and lower scraper. The gap between the upper scraper and the lower scraper and the glue roller is controlled by controlling the adjustment cylinder, thereby realizing the production requirements of paper of different specifications.

[0010] The metering roller is provided with a gap adjustment and digital display device. Since the gap between the gluing roller and the metering roller is set differently for papers of different thicknesses, workers control the amount of glue applied to the paper by controlling the gap between the gluing roller and the metering roller during production. This part is prior art and will not be described in detail here.

[0011] The equipment frame is also provided with a scraper assembly corresponding to the metering roller, which scrapes off excess resin glue, controls the amount of glue on the glue coating roller, and ultimately controls the amount of glue coated on the finished paper. This part is prior art and will not be repeated here.

[0012] The upper scraper, the lower scraper and the scraper assembly are all made of steel ink scraper blades.

[0013] The equipment frame is provided with a glue receiving groove, and a glue groove recovery device is arranged under the glue coating roller and the metering roller, so that the scraped glue passes through the recovery groove and enters the recovery glue tank for repeated use.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The scraper arranged above the glue coating roller of the utility model can scrape off the paper hair on the glue coating roller, ensure the purity of the glue liquid, avoid the occurrence of streaks on the paper, and thus ensure the workshop environment when the downstream customers fold the paper.

The gap size between the two rollers can realize the production requirements of different specifications of paper; the metering roller 10 is provided with a gap adjustment and digital display device. Since the gap between the glue roller 2 and the metering roller 10 is different for papers of different thicknesses, workers control the amount of glue applied to the paper 3 by controlling the gap size between the glue roller 2 and the metering roller 10 during production. This part is the prior art and will not be described in detail here; the equipment frame 1 is also provided with a scraper assembly corresponding to the metering roller 10, which scrapes off excess resin glue, controls the amount of glue on the glue roller 2, and finally controls the amount of glue applied to the finished paper. This part is the prior art and will not be described in detail here; the upper scraper 6, the lower scraper 9 and the scraper assembly are all made of steel ink scraper blades; the equipment frame 1 is provided with a glue connection groove, and a glue groove recovery device is set under the glue roller 2 and the metering roller 10, and the scraped glue passes through this recovery groove and enters the recovery glue tank for reuse.

[0021] Working process or working principle:

[0022] When in use, the paper 3 is coated with glue through two glue coating rollers 2. After the paper 3 passes through the glue coating rollers 2, the upper scraper 6 is used to scrape off the residual glue and stained paper fibers on the glue coating rollers to avoid the paper fibers from covering the new paper surface when coating with glue again, thereby avoiding streaks on the paper 3, thereby ensuring the workshop environment when downstream customers fold paper. At the same time, when splicing paper rollers, the lower scraper 9 can be used to achieve splicing without separating the glue coating rollers 2.

[0023] The scraper arranged above the glue coating roller 2 of the utility model can scrape off the paper hair on the glue coating roller 2, ensure the purity of the glue liquid, avoid the occurrence of streaks on the paper 3, and thus ensure the workshop environment when the downstream customers fold the paper.
