The tail end of the material receiving roller way is provided with a profile length control mechanism, and the end, close to the cutting table, of the material receiving roller way is provided with a waste length control mechanism. The waste material length fixing mechanism comprises a first mounting seat, a first length fixing baffle and a lifting driving part; the lifting driving part is mounted on the first mounting seat in a position adjustable manner; the lifting driving part is used for driving the first fixed-length baffle to penetrate out of the position below the conveying face of the material receiving roller way and driving the first fixed-length baffle to descend to the position below the conveying face of the material receiving roller way. According to the fixed-length cutting machine for the aluminum profile, the length of a deformed part of the aluminum profile and the length of the whole aluminum profile are fixed, the cutting efficiency is improved, and the waste quantity is reduced.

The utility model relates to the technical field of medical auxiliary tools, in particular to a medical fixing adhesive tape for a dynamic glucometer. The medical fixing adhesive tape for the dynamic glucometer comprises a protective layer, an adhesive layer, a release film and a fixing bracket, the protective layer is rhombic, and a plurality of micropores are formed in the protective layer; the adhesive layer is laid on one side of the protective layer, and the release film is attached to one side, far away from the protective layer, of the adhesive layer; the fixing support comprises a plurality of bottom fixing strips and a plurality of side fixing strips. The multiple bottom fixing strips are arranged in a crossed mode, the two ends of each bottom fixing strip are connected with side fixing strips, the ends, away from the bottom fixing strips, of the side fixing strips are fixed to the edges of the mounting holes, and the side fixing strips extend in the opening direction of the mounting holes so that the bottom fixing strips can extend out of the side, away from the pasting layer, of the protection layer. A mounting cavity is formed between the side fixing strip and the bottom fixing strip, and the mounting cavity is used for mounting the dynamic glucometer. The medical fixing adhesive tape for the dynamic glucometer is good in stability and air permeability.

The present invention discloses a reconfigurable ultra-wideband dipole antenna and a communication system. The reconfigurable ultra-wideband dipole antenna includes: a first radiation section, a second radiation section and a third radiation section arranged in sequence; a first switching matcher, located between the first radiation section and the second radiation section, electrically connected to the first radiation section and the second radiation section respectively, for controlling the working mode of the first radiation section and the second radiation section; a second switching matcher, located between the second radiation section and the third radiation section, electrically connected to the second radiation section and the third radiation section respectively, for controlling the working mode of the second radiation section and the third radiation section; wherein the working mode includes a high-frequency dipole antenna mode composed of the first radiation section and the second radiation section, and a low-frequency dipole antenna mode composed of the first radiation section, the second radiation section and the third radiation section. The embodiment of the present invention can ensure the gain and reliability of the antenna and reduce the volume of the antenna on the basis of ensuring the working frequency bandwidth of the antenna.

The application discloses a flange-free pipe expanding machine and method for heat exchangers, which comprises a stamping mechanism and a supporting tool, the supporting tool comprises a fixed seat, the upper side of the fixed seat is connected with a sliding plate through a slide rail, the upper side of the sliding plate is connected with a bottom plate, the upper side of the bottom plate is connected with a plurality of longitudinally arranged floating blocks, and the upper side of the bottom plate is also provided with supporting blocks; the stamping mechanism comprises a supporting frame, the supporting frame is connected with a stamping driving device, the driving end of the stamping driving device is connected with a lifting positioning plate, the lower side of the lifting positioning plate is connected with a plurality of stamping rods, and the lower end of the stamping rod is connected with a pipe expanding end; the floating blocks arranged on the bottom plate offset the downward pressure of the stamping rods on the cooling pipe during pipe expanding, so that the length of the upper end of the cooling pipe extending out of the tube plate after pipe expanding is sufficient and in a uniform alignment state, and the sealing property and corrosion resistance of the tube plate are ensured.

The utility model discloses a spraying moisturizing device which comprises a cart, an adjusting seat and a water tank, connecting grooves are formed in the two side faces of the adjusting seat, rotating blocks are installed in the connecting grooves, the rotating blocks are connected with a spraying seat, a spraying head is installed on one surface of the spraying seat, a motor is installed on one surface of the adjusting seat, and the motor is connected with a gear. Racks are installed on the two side faces of the inner wall of the adjusting base, one surface of each rack is fixedly connected with a limiting block, and one surface of each limiting block is connected with a connecting rod.
