Description

Technical Field

[0001] This utility model relates to the technical field of doctor blade mechanisms, specifically a doctor blade mechanism for coating release paper. Background Technology

[0002] Existing scraper mechanisms typically place components such as sliders, side plates, and platform plates on the left and right sides of the lifting plate. While this layout allows for left and right adjustment, it has significant drawbacks in practical operation. Firstly, this design results in a larger overall width of the equipment, occupying more space and hindering compact layout and placement, especially in environments with limited production space, thus increasing the equipment's footprint. Secondly, when disassembling or installing the scraper, operators must work from both sides of the equipment in confined space, making operation inconvenient and increasing maintenance and adjustment time costs. Therefore, a scraper mechanism that optimizes space layout, is easy to operate, and offers convenient adjustment is needed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a doctor blade mechanism for release paper lamination, which can solve the problems in the prior art.

[0004] This utility model is achieved through the following technical solution: A scraper mechanism for release paper lamination according to this utility model includes a lifting plate, a scraper mounting groove is provided in the lifting plate, and a scraper is snapped into the scraper mounting groove. The scraper is characterized in that two protrusions are fixedly provided on the front side of the scraper, and an inner groove is provided in the protrusion. A sliding limiting component is provided on the lifting plate to limit and fix the scraper when it is snapped into the scraper mounting groove and to limit and fix the inner groove and the protrusion.

[0005] A further technical solution includes a right-angle plate, on which a locking block is fixedly mounted. The right-angle plate and the locking block are guided and slid by a guide rail slider structure. After sliding, the locking block engages with the inner groove, and the right-angle plate abuts against the side end face of the protrusion. The front side of the lifting plate is also provided with a threaded shaft structure for adjusting the guide rail slider structure.

[0006] A further technical solution includes a guide rail slider structure comprising a slide rail fixedly disposed on the front side of the lifting plate, a slider slidably disposed on the slide rail, and the slider being fixedly connected to the right-angle plate through a connecting plate assembly.

[0007] A further technical solution is that the connecting plate assembly includes a side plate fixedly disposed on the lower side of the slider, a platform plate perpendicular to the side plate is fixedly disposed on the rear side of the side plate, and a right-angle plate is fixedly disposed on the upper surface of the platform plate.

[0008] A further technical solution includes a threaded shaft structure comprising a rotating shaft disposed on the front side of the lifting plate, a threaded shaft rotatably disposed on the front side of the slide rail, the threaded shaft passing through the slider, the threaded shaft being threadedly connected to the slider, the threaded shafts on the left and right sides having opposite thread directions, and a coupling being disposed between the threaded shaft and the rotating shaft, the coupling being a power connection between the rotating shaft and the threaded shaft.

[0009] In a further technical solution, a rotating seat is provided on the front side of the slide rail and the lifting plate, and the rotating seat is rotatably connected to the threaded shaft.

[0010] In a further technical solution, a first rotating wheel is fixedly disposed on the outer surface of the rotating shaft.

[0011] The beneficial effects of this utility model are: First, by setting a rotating shaft, a first rotating wheel, a coupling and a lifting plate on the front side of the lifting plate, the slider, side plate, platform plate, locking block and right angle plate can be adjusted to move closer or further away at the same time, so as to facilitate the convenient disassembly or installation of the scraper.

[0012] Second, the slider, side plate, platform plate, locking block, and right-angle plate are configured to move horizontally and vertically. These components are positioned on the front side of the lifting plate. When they move to the left or right, the scraper disengages from the inner groove, allowing it to be removed directly from the underside of the inner groove. This spatial design is reasonable and avoids the limitations of traditional methods that place these components on the left or right sides of the lifting plate, resulting in a wider mechanism. Furthermore, the movement of these components increases the overall width of the mechanism, making it inconvenient for placement and use.

[0013] Third, by setting the shape structure of the side plate and platform plate, the slider, side plate, platform plate, locking block and right angle plate can be set on the front side of the lifting plate for sliding. On the one hand, it satisfies the support stability of the locking block and right angle plate, and on the other hand, it makes the structure of the equipment more compact.
