2results about How to "Solve bridging" patented technology

The present application relates to the technical field of furniture surface decoration, and particularly relates to a production process of gold foil and silver foil pasting on the surface of wooden furniture, which comprises primer sanding treatment, intelligent glue spraying and thickness control, foil pasting and drying, special adhesive enhancement intermediate layer construction for silver foil and PU topcoat spraying. The intelligent glue spraying adopts a laser displacement sensor to detect the wet glue film thickness in real time, to adjust the spraying gun parameters through closed-loop feedback, and to automatically identify the edge and corner areas through an edge detection algorithm to independently control the spraying amount, thereby solving the problem of edge and corner bridging. When pasting the silver foil, a polyurethane modified acrylic resin intermediate layer is sprayed, and a chemical bond is formed after baking, thereby enhancing the adhesion of the silver foil. The drying process adopts normal temperature waiting for drying, medium temperature baking and secondary pressing after cooling. The present application realizes high uniformity control of the glue thickness, reduces the edge and corner bridging rate to below 0.5%, enhances the adhesion of the silver foil to level 0, and significantly improves the product quality consistency and weather resistance.

The application discloses an on-line feeding device of a continuous emulsification process and relates to the technical field of on-line feeding devices.The on-line feeding device comprises a chassis, a material conveying unit arranged on the surface of the chassis and used for material processing and conveying, a hopper fixed to the surface of the chassis, a first valve rotatably connected to the bottom of the hopper and a fixing frame fixed to the top end of the hopper, the inside of the fixing frame is equipped with three hoppers, the surface of each hopper is provided with a feeding opening, and the bottom of each hopper is rotatably connected with a second valve; the inside of each hopper is commonly provided with a dredging unit used for preventing the bridging of the hopper, and the inside of each hopper is provided with a discharging unit used for accelerating the discharging of the hopper, and the discharging unit is linked with the dredging unit, the scraper is arranged, when the scraper is driven to rotate by the motor through the gear and the gear ring, the scraper can automatically move around the inner wall of the hopper, the bridging problem in the hopper can be effectively solved, and the problem that the discharging opening of the hopper is blocked can be avoided.
