The invention discloses a transsclera continuous drug delivery device for eye disease treatment and a preparation method thereof. The device comprises an arc body, a wing-shaped fixing plate and a fixing band. A groove is formed in the bottom surface of the arc body; the two wing-shaped fixing plates are symmetrically arranged on the two sides of the arc body. The two wing-shaped fixing plates are respectively accommodated under the abdomen of the external rectus and under the abdomen of the lower rectus; the fixing belts are fixedly connected to the bottom face of the arc body, and gaps are formed between the fixing belts and the inner wall of the groove and used for storing medicine films; the ends, away from the arc body, of the two-wing-shaped fixing plates are spaced, and the arc body and the two-wing-shaped fixing plates are integrally in a C shape. The eye drops can be well attached to eyeballs, compression on the eyeballs is reduced, free rotation of the eyeballs is not affected, wearing comfort and medicine bioavailability are improved, medicine components are prevented from leaking to the keratoconjunctival surface and fascia tissue, medicine is prevented from going into blood pressure circulation through conjunctival blood vessels and lymphatic vessels, and the risk of side effects of the whole body is reduced; and toxicity and adverse reactions are reduced.

The present application provides a kind of composite material laminated board for shoe, including multiple carbon fiber layers and multiple polyimide fiber layers, adjacent fiber layers are bonded together by resin adhesive, multiple polyimide fiber layers are not adjacent to each other, and each polyimide fiber layer is separated from another polyimide fiber layer by multiple carbon fiber layers;The present application also provides a kind of sole component comprising the above laminated board;A kind of shoe product comprising the above sole component;And the method for preparing the laminated board, by controlling the sequence, uniformity, direction and the like of fiber laying in laminated board, the mechanical properties of composite material laminated board are improved, a kind of polyimide fiber / carbon fiber hybrid reinforced resin matrix composite laminated board with high strength, high toughness and light weight is prepared, and the comprehensive performance and service life of the laminated board for shoe are further improved.

This invention provides a composite material laminate for footwear, comprising multiple carbon fiber layers and multiple polyimide fiber layers. Adjacent fiber layers are bonded together with a resin adhesive. The multiple carbon fiber layers include multiple paired adjacent carbon fiber layers. In each paired carbon fiber layer, the fibers of one carbon fiber layer are laid at an acute clockwise angle α relative to the front-back direction, and the fibers of the other carbon fiber layer are laid at an acute counterclockwise angle α relative to the front-back direction. This invention also provides a sole component including the above-mentioned laminate; a shoe product including the above-mentioned sole component; and a method for preparing the laminate. By controlling the direction, sequence, and uniformity of fiber laying, the mechanical properties of the composite material laminate are improved, resulting in a high-strength, high-toughness, and lightweight polyimide fiber / carbon fiber hybrid reinforced resin-based composite material laminate, thereby improving the overall performance and service life of the footwear laminate.

The application discloses a kind of automatically slitting inductance protection bearing tape preparation equipment and preparation method thereof, comprising: conveying table, heat pressing device, cutting device and cooling device are sequentially arranged in conveying table two sides from left to right;Including the following steps: S1, accurate positioning is carried out to bearing tape by positioning structure and position is corrected;S2, bearing tape is contacted with heater by positioning pressing plate and is pressed down, and the edge of bearing tape is softened;S3, the both sides of bearing tape are cut simultaneously by blade;S4, bearing tape is rapidly frozen and cooled by liquid nitrogen injection part, and then the bearing tape piece is blown to the blanking transmission part by air injection part, and the blanking of single bearing tape piece is completed.The application effectively solves the problem of curling caused by uneven stress distribution by combining heating treatment, arc cutting and air blowing blanking, improves production efficiency, improves product quality and stability, reduces manual operation and error, and reduces production cost.
