6results about How to "Easy to creasing" patented technology

This utility model discloses a cardboard box creasing device for cardboard box production, comprising: a base, a worktable at the upper end of the base, a placement platform rotatably connected to the upper surface of the worktable, two vertical plates slidably connected to the upper surface of the placement platform, horizontal plates fixedly connected to the side walls of the two vertical plates, a movable groove in the middle of each of the two horizontal plates, a limiting groove on the lower surface of a mounting rod, two limiting blocks slidably connected inside the limiting groove, a first creasing rod fixedly connected to the lower end of each of the two limiting blocks, a locking groove at both ends of each of the two first creasing rods, a locking block inside the locking groove, and a second creasing rod fixedly connected to the side wall of the locking block. This structure facilitates the adjustment of the cardboard box position, and by adding creasing rods, the length of the creasing rods can be increased, allowing them to creasing boxes of different sizes, thus improving the utilization rate of the device.

The utility model discloses a 2.5 D glass diaphragm laminating device, which comprises a workbench, the glass is horizontally placed on the workbench; the bearing film is horizontally laid on the plane, away from the workbench, of the glass, and a rectangular groove is formed in the plane, located on one side of the glass, of the bearing film; the diaphragm is adaptively placed in the rectangular groove; the driving assembly is installed on the workbench and connected with the roller, the lowest point of the roller makes contact with the side, away from the glass, of the bearing film, the axial direction of the roller shaft is consistent with the width direction of the glass, and the driving assembly can drive the roller to move in the extending direction of the bearing film and meanwhile drive the roller to rotate around the axis of the roller; compared with the prior art, the bearing film is additionally arranged outside the diaphragm creatively; by means of the design, direct contact between the roller and the membrane is effectively avoided, so that indentation caused by friction between the membrane and the roller when the membrane is rolled and attached is avoided, and bubbles caused by direct contact between the roller and the membrane in the initial pressing stage are also prevented.

This utility model discloses a cardboard creasing device, comprising two side frames arranged symmetrically to the left and right, with a top plate connecting the side frames. A pressure plate is located at the bottom of each side frame, and wheel holes are formed on the pressure plate. Wheel frames are located on the left and right sides of the wheel holes, respectively, and guide wheels extending out of the wheel holes are rotatably connected between the wheel frames. A wheel axle extending laterally through the side frames passes through the side frames, and a rolling roller is rotatably connected to the wheel axle. A horizontally oriented "E"-shaped composite hole is formed on each side frame, and the wheel axle is slidably connected within the composite hole. The composite hole includes an upper adjustment hole extending vertically to the highest position, a lower adjustment hole extending vertically to the lowest position, and a middle adjustment hole extending vertically to the middle position. A mounting ring is fitted onto the wheel axle between the side frames and rotatably connected to the wheel axle. A tension spring connects the mounting ring to the top plate. This creasing mechanism features adjustable creasing depth, convenient adjustment, complete overall function, and strong practicality.

The present application relates to the technical field of food contact packaging material preparation, and discloses a preparation method of a food contactable heat preservation and insulation carton of spray coating aerogel. After the surface of a paper base material is cleaned and activated, a bottom coating layer containing a cellulose affinity group, a bio-based polysaccharide cross-linked heat insulation coating layer containing food contact grade silica aerogel particles and a food contact grade transparent protective layer are formed in sequence. The obtained carton can reduce the risk of migration of aerogel particle pulverization, maintain the stability of the paper base interface bonding, and form a heat preservation and insulation surface that can contact food.
