An easy-print packaging sheet and a manufacturing method therefor. Raw materials of the easy-print packaging sheet contain polyethylene; the smoothness of the packaging sheet is 70-250 seconds; the drape coefficient of the packaging sheet is 78-92%; the burst index of the packaging sheet is 8-15 kPa·m2 / g; and the light shielding rate of the packaging sheet is 85-95%. The packaging sheet having good comprehensive performance is prepared by means of a flash spinning process and the improvement of raw materials and a spinning process.

This application provides a storage device, a warehousing robot, and a warehousing system, relating to the field of warehousing technology. The storage device includes a crossbeam and two extension arms. The crossbeam extends along a first direction, and the two extension arms are arranged at intervals relative to each other along the first direction. Each extension arm includes a first end and a second end. The first end is fixedly connected to the crossbeam, and the second end extends away from the crossbeam along a second direction. Both the first and second directions are located on a horizontal plane, and the first and second directions form an angle. Each extension arm includes a bearing surface, and the bearing surfaces of the two extension arms together form a storage position for holding a material box. Each extension arm includes a first guide portion and a second guide portion. The first guide portion guides the material box into the storage position when its entry direction is parallel to the vertical direction, and the second guide portion guides the material box into the storage position when its entry direction is parallel to the second direction. This storage device can adapt to various application scenarios and improve the user experience.

This utility model relates to the field of steam turbine technology, specifically to a fir-tree type blade root structure, blades, and a steam turbine. The fir-tree type blade root structure provided by this utility model includes a blade root with a first side and a second side arranged opposite to each other. The first side is located on the back arc side of the blade root, and the second side is located on the inner arc side of the blade root. The second side has a protruding structure, and the first side has grooves corresponding to the protruding structures. The blade roots of each pair of adjacent blades interlock through the protruding and groove structures. The interlocking of the blade roots between each pair of blades, through the protruding and groove structures, allows the blade roots to mutually restrain each other during operation, limiting the circumferential sway range of the blades, thereby solving the problem of blade swaying due to low centrifugal force when the blades are lightweight or operate at low speeds.

This invention relates to an explosive granulation device, comprising a reciprocating arm (1), a screen (2), a grinding wheel (3), and an adjusting component (4); the reciprocating arm (1) comprises a symmetrically arranged left arm and a right arm, which reciprocate up and down in opposite directions around the center point where they connect; the two ends of the strip screen (2) are respectively fixed on the left and right arms of the reciprocating arm (1), forming a V-shaped structure; the grinding wheel (3) is disposed on the inner surface of the V-shape of the strip screen (2), and a spindle (7) is disposed on the axis of the grinding wheel (3); the adjusting component (4) is connected to both ends of the spindle (7) of the grinding wheel (3) and is used to adjust the contact pressure between the grinding wheel (3) and the surface of the strip screen (2). This invention has a simple structure, is easy to form a continuous production line with upstream and downstream equipment, is easy to control, and has high reliability; it occupies little space, has a wider range of product size applicability, good safety, and is convenient to maintain.

This utility model relates to the field of vehicle parts technology, and in particular to an anti-slip sleeve for a side support bracket. It includes a sleeve body, which is hollow in shape. An installation hole is provided on its outer side wall, and a kicking device is provided on the opposite side of the installation hole. A plastic base is provided on the bottom surface of the sleeve body, and a metal anti-slip plate is fitted and snapped onto the bottom surface of the base. The anti-slip plate enhances the friction and stability between the side support bracket and the ground. This anti-slip sleeve improves wear resistance and anti-slip properties, and extends its service life.
