7results about How to "Avoid affecting the printing effect" patented technology

This application belongs to the field of semiconductor processing technology, specifically relating to a backlight reflective layer printing device and its application. This application effectively controls the vibration generated during the printing process by optimizing the mechanical structure and position design of the frame, support plate device, and multi-axis spindle, reducing the deviation between the actual operating path and the planned path of the piezoelectric jet valve. This significantly improves the stability of the piezoelectric jet valve operation and the printing accuracy. Furthermore, this application, by setting up a micro-adjustment device, a positioning system, an inkjet calibration system, and a needle alignment device, and utilizing their coordinated relationship, can precisely correct printing parameters such as the jetting position or jetting volume of the piezoelectric jet valve. Therefore, based on the aforementioned stable printer body structure, the coating quality of the backlight reflective layer obtained by piezoelectric jet printing will be further improved. Thus, the backlight reflective layer prepared using this invention has better thickness uniformity and a better reflective effect.

This utility model relates to the field of 3D printers, specifically to a base structure for an LCD photopolymerization 3D printer. It includes a material tank, which is a through-frame structure with a pressing frame fixedly connected to its lower surface. The pressing frame presses and fixes a release film to the bottom surface of the material tank. A base, which is a through-platform structure, has a mounting platform on its top surface for mounting an LCD screen. An annular groove A surrounds the mounting platform on the base, the size of which matches the lower structure of the pressing frame. A through-hole is provided on the mounting platform for the LCD screen's ribbon cable to pass through. When the material tank is installed on the base, the release film adheres to the LCD screen and covers the mounting platform. The release film is an oxygen-permeable membrane. This utility model allows oxygen to pass through the breathable release film because of the resin's oxygen-inhibiting properties, preventing a single ultra-thin layer of liquid resin from curing.

The present application relates to the technical field of photographic paper coating, and particularly relates to a water-based coating for dye ink special PP synthetic photographic paper for increasing the film covering firmness of hot mounting film and a preparation method thereof, the water-based coating for dye ink special PP synthetic photographic paper for increasing the film covering firmness of hot mounting film contains the following components in 100% by mass: modified silicon dioxide 10-20%, polyvinyl alcohol 25-35%, polyurethane-acrylic hybrid emulsion 8-15%, nano boehmite 2.5-3.5%, dispersant 1.5-2.5%, thickening agent 0.5-0.7%, leveling agent 0.2-0.4%, defoaming agent 0.3-0.5%, expanding agent 2-4%, accelerator 0.5-1.5%, mildew-proof agent 0.1-0.3%, ammonia water 0.1-0.3%, and the rest is deionized water. The water-based coating prepared by the present application has good ink absorbability, strong film covering firmness after hot mounting film covering, and high ink adaptability.

This utility model relates to the field of garment processing technology and discloses a flattening device for handling wrinkles in garment fabrics. It solves the problem that existing garment fabric printing devices cannot effectively flatten the fabric before printing, causing wrinkles to affect the printing effect and reduce printing quality. The device includes a worktable, with a support frame fixedly installed on one side of the top of the worktable. Support legs are fixedly installed at both ends of the bottom of the worktable. A pneumatic push rod is fixedly installed on the top of the support frame. The transmission end of the pneumatic push rod passes downward through the support frame and is fixedly installed with a connector. Insert rods are fixedly installed on both sides of the connector via connecting strips. Insertion holes are opened on both sides of the top of the support frame, and two insert rods are slidably installed inside the two insertion holes. A printing machine is fixedly installed at the bottom of the connector. This garment fabric printing device can effectively flatten the fabric before printing, avoiding wrinkles from affecting the printing effect, thereby improving printing quality.

The application provides a high-flame-retardant wear-resistant nylon engineering blanket printing production device, which comprises, in sequence along a feeding direction, an upper blanket mechanism, an inkjet mechanism, a high-temperature color fixing mechanism and a washing mechanism. The upper blanket mechanism comprises, in sequence along a feeding direction, an unfolding assembly, a soaking assembly and a pressing assembly. The inkjet mechanism comprises a conveying assembly, a nozzle assembly and a moving assembly. The conveying assembly comprises a conveying frame, a front conveying roller group arranged on the front side of the conveying frame and a rear conveying roller group arranged on the rear side of the conveying frame. The moving assembly is arranged on the upper side of the conveying frame. The nozzle assembly is mounted on the moving assembly and is driven by the moving assembly to move on the base blanket to print patterns. The unfolding assembly is arranged. A loose winding motor drives a loose winding roller to rotate and drive the base blanket roll to be automatically loosened. The unfolding frame can unfold the base blanket and flatten the base blanket from a curled state. Then, the base blanket is conveyed in a forward direction and a reverse direction through a plurality of unfolding rollers to ensure that the base blanket is fully unfolded for printing.
