This utility model provides an extrusion molding machine for tote bags, relating to the technical field of extrusion molding machines for tote bags. The utility model includes an extruder, a cooling rack, and a molding machine. One end of the extruder is fixedly connected to an outlet, and a fan duct is installed at the top of the outlet. A cutter is installed at the top of the molding machine. A cooling rack is installed on the side of the extruder, and a take-up roller is installed on the side of the cooling rack. A cooling device is installed on the surface of the cooling rack. The cooling device includes a rectangular plate fixedly connected to the side of the cooling rack, an air ring fixedly connected to the side of the rectangular plate, an air pump fixedly connected to the bottom of the air ring, a through groove on the inner wall of the air ring, and an adjusting ring rotatably connected inside the air ring. A through groove is also installed on the side of the adjusting ring. This utility model solves the problem of inconvenient cooling of extruded films.

This utility model relates to the field of medical device technology, specifically a postoperative prone device for ophthalmic surgery. It includes a mattress and a head support assembly. The mattress comprises a main body and three detachably mounted first, second, and third pads. Each of the main, first, second, and third pads has an inflation / deflation assembly on its side. The head support assembly includes an adjustable bracket and a prone pillow. The adjustable bracket is placed at the head of the main body, and the prone pillow is detachably mounted on the adjustable bracket and is tilted. The prone pillow has a notch facing the main body. This postoperative prone device for ophthalmic surgery maintains the main, first, second, and third pads in a suitable inflation state, and the air volume of the first, second, and third pads can be adjusted as needed. Obese patients can also adjust the angle of the prone pillow themselves, providing support and fixation for their heads.

This invention provides a vacuum composite LNG cryogenic pipeline, comprising four functional layers from the inside out: an inner composite pipeline layer, a vacuum layer, an outer composite pipeline layer, and an outer sheath layer. The inner composite pipeline layer consists of an inner spiral wire layer, a sealing layer, a braided layer, another sealing layer, and an outer spiral wire layer, arranged sequentially from the inside out. The vacuum layer is formed by an annular area between the inner and outer composite pipeline layers, supported by an insulating gasket ring, providing vacuum insulation. The outer composite pipeline layer consists of inner and outer spiral wire layers as its innermost and outermost layers, a sealing layer as its second layer, and a braided layer as its third layer. The outer sheath layer comprises an outer sheath. This invention offers superior bending flexibility and low bending stiffness, making it less prone to fatigue damage under external tensile and bending cyclic loads. It also provides excellent insulation, more rational stress transmission in cryogenic pipelines, and a wider range of applications.
