7results about How to "Guaranteed surface flatness" patented technology

This utility model relates to the field of building decoration and discloses an elevated adjustable floor system, including a support plate, a panel on top of the support plate, and a bracket below the support plate for supporting the support plate. The panel is magnetically attached to the top surface of the support plate. The panel can be fixed to the top surface of the support plate by magnetic attachment, replacing the traditional leveling layer. This ensures a flat floor while enabling rapid installation and facilitates individual panel replacement, simplifying the process and avoiding wasted labor. Furthermore, the modular design allows for pre-processing of corresponding panels, reducing on-site construction and pollution, and significantly improving construction speed. The bracket and support plate are fixed by pins, requiring only plug-in assembly, making construction convenient and quick. This simplifies the process and reduces project costs.

The invention relates to the technical field of lined paper processing equipment, in particular to a rolling device for lined paper production, which comprises a side connecting frame, a rolling roller is rotatably connected to the inner end face of one side of the side connecting frame, a shaft rod is fixedly connected to one side of the middle of the rolling roller, and the inner arc surface of the rolling roller is sleeved with an arc-shaped pressure relief shaft sleeve. An air cavity is formed in the inner arc face of the arc-shaped pressure relief shaft sleeve, and a shaft moving block is slidably connected to the upper end of the outer arc face of the shaft rod. Through a cooperative stress absorption structure of the arc-shaped pressure relief shaft sleeve and the arch-shaped bomb frame, the top of the arch-shaped bomb frame sinks and the bottom of the arch-shaped bomb frame expands outwards to deform in a self-adaptive mode by means of pressure transmission of the air cavity. The structure can actively absorb outer-layer extrusion stress borne by the inner-layer coiled material, the stress is synchronously dispersed to the elastic roller surface through reverse supporting of the arch-shaped elastic frame on the arc-shaped pressure relief plate, creep deformation of the inner-layer coiled material is effectively relieved, the problem that the tightness degree inside and outside the coiled material is inconsistent is solved, and the quality defect of edge cracking and warping in the subsequent slitting process is reduced.

The application discloses a transfer glue special for transfer high-gloss tipping paper and a preparation method thereof, and aims to solve the defects of poor environmental protection, insufficient water resistance, large curing shrinkage and the like of the existing transfer glue.
